Subject: [PATCH 002/311] feat(desktop): reload a tab from its right-click menu
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Right-click any tab and pick Reload: the pane's content remounts in
place — effects re-run, state resets, measurements are retaken — while
the tab keeps its slot and every other tab is untouched.

A per-pane epoch atom keys the contribution inside the zone body, so
reload never rewrites the layout tree. Both tab menus offer it: the
zone strip menu (tool panels, the file tree, a fresh draft's main tab)
and the session tab menu (tiles + the loaded main tab).

Subject: [PATCH 003/311] fix(approval): classify CLI/TUI approval timeouts
 separately from explicit denials
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

When an approval prompt expired without a response, every CLI-side path
collapsed the timeout into the same 'deny' choice as an explicit user
refusal, so the agent was told the user denied the action when the user
simply never answered. The gateway wait already distinguished the two
('timed out without user response... Silence is not consent.'); this
brings the CLI/TUI/ACP surfaces to parity.

- prompt_dangerous_approval(): input()-path expiry now returns a distinct
  'timeout' choice (still fail-closed).
- cli.py _approval_callback + hermes_cli/callbacks.py approval_callback:
  deadline expiry returns 'timeout' instead of 'deny'.
- check_all_command_guards / _run_approval_gate CLI tails: 'timeout' maps
  to outcome='timeout' with a 'timed out without user response... Silence
  is not consent.' BLOCKED message (matching the gateway wording);
  explicit deny keeps outcome='denied' and gains user_consent=False for
  shape parity.
- computer_use: 'timeout' verdict threads through the CLI adapter and
  yields a 'prompt timed out — the user did not respond' error instead of
  'denied by user'.
- ACP permissions bridge: FutureTimeout returns 'timeout' (other failures
  still 'deny'); elicitation maps 'timeout' to 'cancel' like the gateway's
  unresolved outcome; codex wire mapping documents deny/timeout→decline.
- write_approval already treats unknown choices as 'stage, not drop', so
  a timeout now stages the memory write instead of silently refusing it.

Every timeout path remains fail-closed — the action never runs; only the
classification reported to the agent changes.

Subject: [PATCH 004/311] fix(desktop): paste rich text with images as text,
 not blank attachments
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Copying a Discord thread (or any rich-text selection with images) attached
one or more blank thumbnails and dropped the message text entirely.

Two causes. The clipboard's `text/html` was scraped for inline
`<img src="data:…">` regardless of whether the copy carried its own text —
and what Discord ships beside each image embed is a 32x5 blurhash
placeholder, which is exactly the blank attachment. Then, because any image
blob short-circuited the paste handler, the prose that came with it never
reached the composer.

Inline HTML images now only count for an image-only copy, and are ignored
below a thumbnail-sized floor so spacers and trackers don't attach either. A
mixed paste attaches its real images and still inserts its text.

Also registers pasteAndMatchStyle in the Edit menu — Cmd+Shift+V had no menu
entry, so the chord was never translated into an editor command anywhere in
the app.

Subject: [PATCH 005/311] fix(cli): persist YOLO mode across --resume
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

A session's YOLO bypass lived only in the in-memory
tools.approval._session_yolo set (or the process-frozen --yolo env
var), so resuming a session in a fresh process silently reverted the
user's /yolo ON — dangerous commands started prompting again.

Persist a yolo_mode flag in the session row's model_config JSON and
restore it on every CLI resume path:

- SessionDB.set_session_yolo() merges the flag into model_config
  (same lineage-preserving merge as update_session_runtime_lock);
  SessionDB.session_yolo_enabled() reads it back, false on any parse
  failure.
- /yolo toggle persists ON and OFF through the new helper; the
  compression/branch session-id rotation carries the flag onto the
  continuation row.
- --yolo launches record the flag at session creation (agent_init),
  and a /yolo toggled before the lazily-created row exists is carried
  into the creation-time model_config (_ensure_db_session).
- HermesCLI._restore_session_yolo() re-enables the bypass on startup
  --resume/-c, the deferred init path, and mid-chat /resume, with a
  visible '⚡ YOLO mode restored from session' notice. No-op under a
  frozen process-wide --yolo and never enables on absent/garbage flags.

Subject: [PATCH 011/311] fix(tui): snapshot history after pending model switch
 applies (#76870)

Deferred model switches append a marker and bump history_version at
turn start; the dispatcher was snapshotting history before that
mutation, so the version-mismatch guard rejected the turn's own
result as a stale/concurrent write. Move the snapshot to after
_apply_pending_model_switch/_sync_agent_model_with_config, under
history_lock, so the turn's own preparatory mutation is included in
its baseline while the anti-stale guard still catches real external
writes.

+## Identificação
+
+- Issue: [#76870 — Model switch mid-session triggers history_version mismatch](https://github.com/NousResearch/hermes-agent/issues/76870)
+- Estado consultado em 2026-08-02: aberta, sem responsável, sem comentários.
+- Labels: `type/bug`, `comp/tui`, `P1`, `sweeper:risk-session-state`, `area/sessions`.
+- Superfície afetada: `tui_gateway`, usada por TUI/Desktop/Webapp via JSON-RPC.
+- Branch local analisada: `fix-76574-secret-scope-residuals`.
+
+## Veredito
+
+**Issue verídica. Implementação necessária e realizada.**
+
+Foi reproduzido deterministicamente o defeito causal: uma troca escolhida enquanto um turno está rodando fica em `pending_model_switch`; no início do turno seguinte, o gateway capturava `history` e `history_version` antes de aplicar essa troca. A aplicação da troca adiciona o marcador de modelo ao histórico e incrementa a versão. Ao terminar, o próprio turno é classificado incorretamente como concorrente/stale e seu resultado não é gravado no histórico da sessão.
+
+A evidência local confirma o primeiro turno após a troca. O relato de 75+ mensagens vazias no SQLite é evidência operacional fornecida pelo autor; esse volume completo não foi reproduzido localmente sem o banco e ambiente Docker citados. A correção elimina o desync inicial que inicia a cadeia, sem relaxar o guard defensivo.
+
+## Evidência da issue
+
+O autor relata:
+
+- Docker com s6-overlay, perfil `default`.
+- Troca `minimax-m3` → `deepseek-v4-pro`, provider `ollama-cloud`.
+- Sessão `20260802_151208_b9d649`.
+- Log: `history_version mismatch (expected=1 current=2)`.
+- Respostas visíveis pelo stream WebSocket, mas histórico/DB inutilizável para busca, resume, rewind, undo e cron `context_from`.
+- Workaround: executar `/new` antes da troca.
+
+## Causa raiz confirmada
+
+Sequência defeituosa anterior:
+
+1. `config.set model` durante turno ativo não troca cliente em uso; salva escolha em `session["pending_model_switch"]`. Isso é correto e evita race entre modelo/client/base URL.
+2. `_run_prompt_submit()` do próximo turno copiava `session["history"]` e `history_version` no dispatcher, antes de iniciar worker.
+3. Worker chamava `_apply_pending_model_switch()`.
+4. `_apply_model_switch()` chamava `_append_model_switch_marker()`.
+5. Marcador era anexado e `history_version` incrementava.
+6. `agent.run_conversation()` recebia snapshot antigo, sem marcador.
+7. Commit final comparava versão antiga com nova, concluía falsamente que histórico mudou externamente e recusava `result["messages"]`.
+
+Defeito nasceu no commit `f27d45e2880b46a2239b184ecc8ab88ecfd2843d` (`feat(tui): ... switch mid-turn`, 2026-07-30). Intenção do commit era válida; erro foi somente ordenação entre aplicação adiada e snapshot.
+
+## Solução implementada
+
+Arquivo: `tui_gateway/server.py`.
+
+Alteração: mover captura de `history` e `history_version` para dentro do worker, imediatamente após `_apply_pending_model_switch()` e `_sync_agent_model_with_config()`, ainda protegida por `history_lock` e antes de qualquer chamada ao modelo.
+
+Nova ordem:
+
+1. Aplicar mutações preparatórias pertencentes ao próprio turno.
+2. Capturar histórico e versão consistentes.
+3. Executar agente com esse snapshot.
+4. Manter comparação final de versão.
+
+Assim, mutação interna esperada entra no baseline. Mutações externas reais ocorridas após snapshot continuam detectadas e rejeitadas pelo guard existente.
+
+### Por que não aceitar qualquer mismatch
+
+A alternativa sugerida pela issue de aceitar resposta mesmo com versão alterada seria insegura: undo, compressão, retry, rollback ou outra escrita concorrente podem invalidar contexto usado para gerar resposta. Sobrescrever histórico nesses casos ressuscitaria mensagens removidas ou perderia estado novo. Guard permanece intacto.
+
+### Por que não remover marcador ou incremento
+
+Marcador informa novo runtime ao modelo e precisa sobreviver em histórico. Incremento representa mutação real. Removê-los esconderia mudança e enfraqueceria invariantes. Problema era snapshot cedo demais.
+
+### Escopo
+
+- 7 linhas produtivas reposicionadas/adicionadas; nenhuma API nova.
+- Nenhuma mudança de schema, tool, config ou prompt global.
+- Sem alteração em persistência SQLite.
+- Sem atualização de Graphify, conforme instrução do projeto.
+
+## Teste de regressão
+
+Adicionado `test_prompt_submit_snapshots_history_after_pending_model_switch` em `tests/test_tui_gateway_server.py`.
+
+O teste simula contrato real:
+
+- sessão começa com versão 0;
+- troca adiada adiciona marcador e eleva versão para 1 no início do turno;
+- agente deve receber marcador no `conversation_history`;
+- resposta deve terminar no histórico;
+- `message.complete` não deve carregar warning de mismatch.
+
+### Prova antes da correção
+
+Resultado esperado e observado:
+
+- teste falhou;
+- agente recebeu `conversation_history=[]`, não o marcador;
+- stderr: `history_version mismatch (expected=0 current=1)`;
+- histórico recusou resposta do agente.
+
+### Prova depois da correção
+
+- `pytest ... -k "history_version or pending_model_switch"`: **5 passed**.
+- `pytest ... -k "model_switch"`: **7 passed**.
+- `ruff check tui_gateway/server.py tests/test_tui_gateway_server.py`: **passou**.
+- `git diff --check`: **passou**.
+
+Suite completa de `tests/test_tui_gateway_server.py`: **501 passed, 2 failed** na primeira execução. Falhas foram testes concorrentes não relacionados (`test_write_json_serializes_concurrent_writes` e `test_run_prompt_submit_requeues_all_unstarted_notifications_with_real_threading`). Ambos passaram juntos ao rerodar isoladamente (**2 passed**), classificando-os como flakes/interferência de suite, não regressão desta mudança.
+
+## Invariantes preservados
+
+- Prompt caching: nenhuma mensagem passada é reescrita durante chamada; snapshot continua estável para o turno.
+- Alternância/histórico: marcador existente continua sendo mensagem `user`, conforme compatibilidade com providers estritos.
+- Concorrência: `history_lock` cobre captura; guard de versão continua protegendo mutações posteriores.
+- Escopo por sessão: nenhuma variável global ou ambiente foi alterada.
+- Persistência: agente e gateway passam a compartilhar o mesmo baseline que contém marcador.
+
+## Risco residual
+
+Baixo. Mudança só desloca momento do snapshot alguns milissegundos para depois da preparação do turno. Se uma mutação externa legítima ocorrer depois da nova captura, mismatch ainda dispara. Se ocorrer antes, ela é incluída no contexto enviado ao agente, comportamento correto porque chamada ainda não começou.
+
+A alegação de que todo turno posterior necessariamente falha não decorre isoladamente do contador: após consumir `pending_model_switch`, nova versão deveria estabilizar. Isso pode refletir efeito secundário do desync inicial ou particularidade do ambiente/banco do relator. Correção cobre causa confirmada sem alegar reprodução do banco original.
+
+## Arquivos alterados
+
+- `tui_gateway/server.py`: ordem correta do snapshot.
+- `tests/test_tui_gateway_server.py`: regressão causal.
+- `ISSUE_76870_RELATORIO_CAUSA_RAIZ.md`: este relatório.
+
+## Conclusão
+
+Não cancelar: bug existe no código atual e foi reproduzido. Correção mínima age na fronteira exata: operações preparatórias primeiro, snapshot depois. Não adiciona abstração, não enfraquece proteção anti-stale e preserva intenção da troca adiada.

-Suite completa de `tests/test_tui_gateway_server.py`: **501 passed, 2 failed** na primeira execução. Falhas foram testes concorrentes não relacionados (`test_write_json_serializes_concurrent_writes` e `test_run_prompt_submit_requeues_all_unstarted_notifications_with_real_threading`). Ambos passaram juntos ao rerodar isoladamente (**2 passed**), classificando-os como flakes/interferência de suite, não regressão desta mudança.
-
-## Invariantes preservados
-
-- Prompt caching: nenhuma mensagem passada é reescrita durante chamada; snapshot continua estável para o turno.
-- Alternância/histórico: marcador existente continua sendo mensagem `user`, conforme compatibilidade com providers estritos.
-- Concorrência: `history_lock` cobre captura; guard de versão continua protegendo mutações posteriores.
-- Escopo por sessão: nenhuma variável global ou ambiente foi alterada.
-- Persistência: agente e gateway passam a compartilhar o mesmo baseline que contém marcador.
-
-## Risco residual
-
-Baixo. Mudança só desloca momento do snapshot alguns milissegundos para depois da preparação do turno. Se uma mutação externa legítima ocorrer depois da nova captura, mismatch ainda dispara. Se ocorrer antes, ela é incluída no contexto enviado ao agente, comportamento correto porque chamada ainda não começou.
-
-A alegação de que todo turno posterior necessariamente falha não decorre isoladamente do contador: após consumir `pending_model_switch`, nova versão deveria estabilizar. Isso pode refletir efeito secundário do desync inicial ou particularidade do ambiente/banco do relator. Correção cobre causa confirmada sem alegar reprodução do banco original.
-
-## Arquivos alterados
-
-- `tui_gateway/server.py`: ordem correta do snapshot.
-- `tests/test_tui_gateway_server.py`: regressão causal.
-- `ISSUE_76870_RELATORIO_CAUSA_RAIZ.md`: este relatório.
-
-## Conclusão
-
-Não cancelar: bug existe no código atual e foi reproduzido. Correção mínima age na fronteira exata: operações preparatórias primeiro, snapshot depois. Não adiciona abstração, não enfraquece proteção anti-stale e preserva intenção da troca adiada.

-# Relatório técnico — Issue #69678 e PRs relacionados
-
-**Data da análise:** 22 de julho de 2026  
-**Repositório:** `NousResearch/hermes-agent`  
-**Issue principal:** [#69678 — SQLite connections leaked in delivery, async delegation, and verification evidence ledgers](https://github.com/NousResearch/hermes-agent/issues/69678)  
-**PR principal:** [#69681 — fix(gateway,tools,agent): close leaked SQLite connections in delivery](https://github.com/NousResearch/hermes-agent/pull/69681)
-
-## Resumo executivo
-
-A issue #69678 descreve um bug real: três ledgers SQLite usam a conexão como context manager, mas nunca a fecham explicitamente. Em processos de gateway de longa duração, as conexões e seus descritores de arquivo podem permanecer vivos até a coleta pelo garbage collector, acumulando descritores para o banco principal, `-wal` e `-shm`. O processo eventualmente pode atingir `RLIMIT_NOFILE` e começar a falhar com `[Errno 24] Too many open files` em componentes não relacionados.
-
-A causa raiz apresentada está correta. O PR #69681 corrige os 21 call sites identificados e preserva as semânticas existentes de transação e locking.
-
-**Conclusão:** #69678 não é duplicata exata de #69567. Ambas pertencem à mesma classe de bug, mas afetam módulos diferentes. O PR #69681 deve ser tratado como fix irmão do PR #69594, não como implementação duplicada.
-
-## Escopo afetado
-
-| Módulo | Call sites afetados | Operações que acionam o ledger | Risco |
-|---|---:|---|---|
-| `gateway/delivery_ledger.py` | 5 | Registro, atualização, recuperação, pruning e inspeção de entregas | Muito alto; executado no fluxo frequente de respostas finais |
-| `tools/async_delegation.py` | 13 | Dispatch, conclusão, recuperação, claim, release e confirmação de entrega | Alto durante delegações em background |
-| `agent/verification_evidence.py` | 3 | Resultado de terminal, edição do workspace e leitura de status | Cresce com operações de desenvolvimento e verificação |
-
-Total confirmado: **21 call sites**.
-
-## Causa raiz
-
-Os módulos usam o seguinte padrão:
-
-```python
-with _connect() as conn:
-    ...
-```
-
-O context manager de `sqlite3.Connection` controla a transação:
-
-- sucesso: commit;
-- exceção: rollback;
-- saída do bloco: não executa `conn.close()`.
-
-Consequentemente, o bloco `with` transmite uma falsa impressão de gerenciamento completo do recurso. A transação termina, mas o lifecycle da conexão não termina de forma determinística.
-
-Em modo WAL, uma conexão pode manter descritores associados a:
-
-- arquivo principal do banco;
-- arquivo `-wal`;
-- arquivo `-shm`.
-
-Em processo curto, encerramento ou coleta rápida pode mascarar o defeito. Em gateway long-lived, sob tráfego recorrente, acúmulo pode alcançar o soft limit de descritores e causar falhas em leituras de configuração, arquivos temporários, sockets e outros bancos SQLite.
-
-## Relação com #69567 e PR #69594
-
-[Issue #69567](https://github.com/NousResearch/hermes-agent/issues/69567) encontrou a mesma falha em `cron/executions.py`. Uma execução normal de cron abre conexões em `create_execution()`, `mark_execution_running()` e `finish_execution()`. O relato mediu crescimento de descritores até atingir limite do processo.
-
-[PR #69594](https://github.com/NousResearch/hermes-agent/pull/69594) propõe um `_transaction()` que:
-
-1. abre a conexão;
-2. preserva commit/rollback com `with conn:`;
-3. fecha a conexão em `finally`;
-4. fecha também quando inicialização de PRAGMA/schema falha.
-
-O PR #69681 aplica o mesmo modelo a três ledgers não alterados pelo PR #69594.
-
-### Decisão sobre duplicidade
-
-**Não marcar #69678 como duplicata de #69567.**
-
-Justificativa:
-
-- causa técnica idêntica;
-- arquivos e call paths diferentes;
-- #69594 altera somente ledger de cron;
-- mesmo após #69594, os 21 sites de #69678 continuariam vazando conexões;
-- busca de PRs relacionados não encontrou outro PR cobrindo os três módulos de #69678.
-
-Classificação correta: issues irmãs pertencentes à mesma classe de defeito.
-
-## Avaliação do PR #69681
-
-### Estado observado
-
-- aberto;
-- não é draft;
-- GitHub o considera mergeable;
-- 1 commit;
-- 6 arquivos alterados;
-- 512 adições e 29 remoções;
-- sem reviews ou comentários no momento da análise.
-
-### Solução implementada
-
-Cada módulo recebe um context manager equivalente a:
-
-```python
-@contextmanager
-def _transaction() -> Iterator[sqlite3.Connection]:
-    conn = _connect()
-    try:
-        with conn:
-            yield conn
-    finally:
-        conn.close()
-```
-
-Além disso, `_connect()` passa a fechar a conexão caso PRAGMA ou inicialização de schema falhe depois de `sqlite3.connect()` ter retornado com sucesso.
-
-### Pontos corretos
-
-- fechamento determinístico em sucesso, early return e exceção;
-- commit e rollback continuam delegados ao context manager nativo;
-- locking existente é preservado;
-- `_transaction()` não adquire `_DB_LOCK`, evitando lock nesting novo;
-- `_prune()` em `delivery_ledger` continua lock-free;
-- contrato schema-on-connect é mantido;
-- todos os 21 call sites são migrados;
-- nenhuma configuração, schema de ferramenta ou superfície core nova é adicionada.
-
-Nenhum defeito funcional foi identificado no patch analisado.
-
-## Minimal fix recomendado
-
-Solução do PR é pequena no comportamento de produção e resolve a causa raiz. Recomendação: manter `_transaction()` local em cada módulo.
-
-Não criar agora um helper SQLite global compartilhado. Isso aumentaria escopo, acoplamento e risco para resolver três módulos independentes. Uma abstração compartilhada só deve surgir após demanda concreta e contrato comum comprovado.
-
-Possíveis reduções sem mudar o desenho:
-
-- encurtar docstrings repetidas dos três `_transaction()`;
-- compartilhar fixture de tracking apenas se já existir local apropriado na suíte;
-- evitar refatorações adjacentes.
-
-O volume `+512/-29` vem principalmente dos três arquivos de regressão. O fix runtime em si permanece cirúrgico.
-
-## Avaliação dos testes
-
-O PR adiciona testes para:
-
-- fechamento em operações normais;
-- update sem linha correspondente;
-- exceção durante operação SQL;
-- falha durante inicialização do schema;
-- igualdade entre número de conexões abertas e fechadas.
-
-Os testes usam conexões SQLite reais envolvidas por um proxy que registra chamadas a `close()`. Isso valida diretamente o contrato quebrado e evita depender do timing do garbage collector.
-
-### Melhoria opcional
-
-Adicionar teste Linux de integração contando `/proc/self/fd` após várias operações. Esse teste reproduziria o sintoma externo, mas pode ser específico de plataforma e mais frágil. Não deve bloquear merge se a suíte direta de lifecycle e suítes existentes estiverem verdes.
-
-Resultados citados pelo autor não foram reexecutados nesta análise, pois checkout local contém várias alterações pré-existentes e branch do PR não foi aplicada. Antes do merge, CI deve confirmar:
-
-```text
-tests/gateway/test_delivery_ledger_fd_leak.py
-tests/tools/test_async_delegation_fd_leak.py
-tests/agent/test_verification_evidence_fd_leak.py
-tests/gateway/test_delivery_ledger.py
-tests/gateway/test_delivery_ledger_producer.py
-tests/tools/test_async_delegation.py
-tests/agent/test_verification_evidence.py
-```
-
-## Issues relacionadas
-
-Mesma classe geral de lifecycle SQLite, mas escopos diferentes:
-
-- [#69567](https://github.com/NousResearch/hermes-agent/issues/69567): cron execution ledger;
-- [#60859](https://github.com/NousResearch/hermes-agent/issues/60859): leak de `SessionDB` em early return;
-- [#30027](https://github.com/NousResearch/hermes-agent/issues/30027): listagem de boards kanban;
-- [#28802](https://github.com/NousResearch/hermes-agent/issues/28802): helpers kanban specify;
-- [#36111](https://github.com/NousResearch/hermes-agent/issues/36111): lifecycle de `ResponseStore` no API server;
-- [#37369](https://github.com/NousResearch/hermes-agent/issues/37369): crescimento de descritores de `response_store.db`.
-
-Essas issues demonstram padrão recorrente: uso de context manager transacional interpretado incorretamente como gerenciamento completo da conexão.
-
-## Possíveis ocorrências residuais
-
-Busca estática encontrou padrões semelhantes fora do escopo do PR, incluindo:
-
-- `gateway/readiness.py`;
-- templates FastMCP em `optional-skills/mcp/fastmcp/templates/database_server.py`.
-
-Esses locais não devem ser incluídos automaticamente em #69681. Cada ocorrência precisa de:
-
-1. confirmação de que conexão não possui outro owner;
-2. reprodução ou teste de lifecycle;
-3. análise da frequência e duração do processo;
-4. fix separado quando comportamento estiver comprovado.
-
-Expandir #69681 para uma auditoria global contrariaria objetivo de mudança cirúrgica.
-
-## Solução estrutural futura
-
-Após merge dos fixes urgentes, abrir tarefa separada de auditoria dirigida:
-
-1. localizar `with sqlite3.connect(...)`, `with connect(...)` e `with _connect(...)`;
-2. classificar conexões por lifecycle: per-operation ou long-lived;
-3. exigir `contextlib.closing`, `try/finally close()` ou helper transacional para conexões per-operation;
-4. adicionar teste de regressão somente para call paths reais;
-5. documentar em guia interno que `sqlite3.Connection` context manager não fecha a conexão.
-
-Evitar mudança mecânica global: alguns componentes podem manter conexão deliberadamente durante lifetime do serviço.
-
-## Recomendação final
-
-1. Não fechar #69678 como duplicata.
-2. Tratar #69594 e #69681 como fixes irmãos.
-3. Aprovar desenho do PR #69681 após CI verde.
-4. Não ampliar PR para ocorrências não reproduzidas.
-5. Criar follow-up separado para auditoria de lifecycle SQLite no repositório.
-
-**Decisão sugerida:** merge do PR #69681 após validação automática e review, seguido pelo fechamento da issue #69678 como concluída.

Subject: [PATCH 013/311] perf(agent): precompile response and skill-scan
 regexes (#33208)

strip_think_blocks passed the same response-scrubbing strings through
re's pattern dispatcher on every response. Skills Guard repeated the
same work for 121 patterns against every scanned line.

Compile the existing expressions once and reuse Pattern.sub/search. Keep
each generic tool-call tag in its own paired expression so mismatched
openers retain their payload while existing stray-closer cleanup remains
unchanged.

Subject: [PATCH 014/311] refactor(agent): rebuild hoisted patterns from shared
 tag-name tuples

Simplify-pass follow-up on the #69653 salvage: the original code built
these patterns from a name loop; hand-expanding them into 10 literals
lost that single source. Tag-name tuples restore it (adding a 6th
reasoning tag is now a one-place change), and the gnarly named-function
pattern regained a pointer to its step-1c rationale. Byte-equivalence
of every rebuilt pattern verified programmatically (alternation-order
neutrality probed: the \b and > anchors make order irrelevant).

Subject: [PATCH 016/311] fix(gateway): defer in-band restart until active
 turns finish (#77184)

request_restart was calling stop() immediately, so the requesting turn stayed
in the drain wait set and got force-killed at restart_drain_timeout. Wait for
active work to reach zero first, then stop against an idle gateway.

Subject: [PATCH 018/311] fix(tui_gateway): drain in-flight turns before
 finalizing sessions on compute-host shutdown
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

ComputeHost.shutdown() called flush_all_sessions() before its own in-flight
turn drain loop. server._finalize_session latches on session["_finalized"]
and every later call returns immediately, so that one flush was spent while
turns were still producing output: the unflushed tail was never persisted,
commit_memory_session wrote long-term memory from a truncated transcript, the
session's DB row was marked ended while it was live, on_session_end fired with
completed=False/interrupted=True against a running session, and the
active-session lease was released out from under a turn. The drain loop exists
precisely so that mid-turn work survives a teardown; finalizing first defeated
it. Reachable from all three teardown paths: the parent/orphan guard (which
os._exit(0)s immediately after), the SIGTERM/SIGINT handler, and stdin close.

Drain first, then flush. A slice of the caller's budget (_FLUSH_RESERVE_SECS,
never more than half of it so a short explicit wait still gets a real drain) is
withheld from the drain so the flush still runs when turns outlast the window:
HostSupervisor SIGKILLs the host _SHUTDOWN_TIMEOUT_SECS after SIGTERM — 10.0s,
the same value as shutdown()'s default wait — so a drain allowed to consume the
whole budget would leave the durability write racing that kill. `wait` itself is
unchanged, so total shutdown latency and the SIGTERM->SIGKILL margin are
unchanged.

Subject: [PATCH 019/311] fix(tui_gateway): bound the shutdown drain sleep by
 the time left to it

The drain loop slept a flat 0.05s per tick, so it could overshoot its deadline
by up to one tick and spend part of the reserve withheld for
flush_all_sessions(). For a small `wait` the reserve is itself half the budget,
so a single overshoot can consume all of it: at wait=0.34 the drain budget is
0.17s but the loop requested 4 x 0.05 = 0.20s of sleep.

Clamp each tick to the remaining time. The new test asserts on the summed
*requested* sleep rather than wall-clock, which is deterministic: every sleep is
bounded by the strictly-decreasing remainder, so the total can never exceed the
drain budget regardless of how the scheduler interleaves.

Subject: [PATCH 020/311] fix(tui_gateway): retain live-turn sessions
 unfinalized when the drain deadline expires
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The drain reserves a slice of the shutdown budget so flush_all_sessions
still runs when in-flight turns outlast the window. But that flush was
unconditional: a session whose turn was still running got its one-shot
_finalize_session spent mid-turn, and the executor.shutdown(wait=False,
cancel_futures=True) immediately after does not join the turn. The
session was then permanently un-finalizable and its active-session lease
had been released out from under live work — the same persistence and
lifecycle race the drain exists to close, just relocated past the
deadline instead of removed.

Give _turn_futures a session association (Future -> sid, the same key
space as server._sessions) at both submit sites, and on deadline expiry
exclude the sids whose futures are still running from the flush. Those
sessions are retained unfinalized and therefore recoverable; sessions
with no live turn finalize exactly as before. The done-callback now pops
under the lock, since a bare dict.pop is not the drop-in set.discard was.

wait semantics, the reserve math and the bounded per-tick sleep are
unchanged, so this adds no shutdown latency. All three shutdown callers
(orphan, sigterm, and the tight stdin_closed wait=2.0 path) funnel
through this one function and are covered.

Subject: [PATCH 021/311] docs: note atexit re-finalization interaction in
 shutdown() docstring
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The PR's skip-live-sessions optimization is partially defeated by
server._shutdown_sessions() registered via atexit (server.py:1172),
which runs on SystemExit after shutdown() returns for the SIGTERM and
stdin_closed paths. The orphan path (os._exit(0)) bypasses atexit.

This is a pre-existing issue — the old finalize-first order had the
same atexit interaction. The comment documents the gap and suggests a
follow-up: gate _shutdown_sessions on not session.get('running').

Subject: [PATCH 025/311] fix(ui-tui): pause status-chrome timers while a
 blocking overlay is open
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

`StatusRulePane` renders `StatusRule` outside the `!isBlocked` guard in
appLayout.tsx, so the status rule stays mounted underneath approval,
model-picker, pager, sessions and every other blocking overlay. Its three
timer-driven components keep firing the whole time: `FaceTicker` (glyph,
1s clock, verb rotation), `SessionDuration` (1s) and `IdleSince` (1s).
Every tick re-renders a rule nobody can see, and in an Ink TUI that churn
reads to the user as the dialog flickering.

Gate all three components' interval creation on the existing `$isBlocked`
computed store, so nothing is armed while an overlay covers the rule.

The pause alone would leave the elapsed read-outs frozen at the moment the
overlay opened, so each effect re-seeds `now` from the wall clock when it
re-arms. `SessionDuration` and `IdleSince` already did this; `FaceTicker`
gains the same re-sync. Closing a five-minute overlay now resumes at the
true elapsed time instead of the pre-overlay value.

No new store is introduced — `$isBlocked` already exists and already ORs
the current OverlayState field set.

Subject: [PATCH 026/311] fix(ui-tui): gate status-rule timers on real
 occlusion, not $isBlocked
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

`$isBlocked` answers "is text input suspended", not "is the status rule
covered". appLayout uses it only to hide the input rows (appLayout.tsx:384);
`StatusRulePane` renders outside that guard, at :365 for `at="top"` and :449
for `at="bottom"`. So the previous revision paused FaceTicker /
SessionDuration / IdleSince under prompts that leave the rule fully on
screen — approval, billing, subscription, confirm, clarify, sudo and secret
all render through PromptZone in NORMAL FLOW above ComposerPane
(appOverlays.tsx:58-162, appLayout.tsx:553-568). They push the rule down;
they do not cover it. Freezing a visible clock is a worse bug than the churn
being removed.

Replace it with `$isStatusRuleOccluded`, a narrow derived store over
overlay + ui state covering only what actually paints over the rule:

- `widget` — the modal widget slot renders at viewport level
  (ActiveWidgetSlot, sdk/host.tsx:209) so it can anchor the full-screen
  absolute `Overlay` against the whole terminal.
- the FloatingOverlays set (modelPicker, pager, petPicker, sessions,
  skillsHub, pluginsHub) — but only when `ui.statusBar === 'top'`. That
  panel is `position="absolute" bottom="100%"` inside ComposerPane's
  relative Box (appOverlays.tsx:387), so it grows UPWARD over the top rule
  and can never reach the bottom one.

Deliberately excluded: the PromptZone flow states above; `agents` and
`journey`, which unmount the entire ComposerPane subtree (appLayout.tsx:553)
so React's effect cleanup already clears the intervals; `ambient`, an
in-flow dock; and composer completions, which share the floating grid but
are a render prop that changes per keystroke — re-arming a 1s interval on
every character would restart the countdown each time and starve the tick.
`statusBar: 'off'` needs no branch: StatusRulePane returns null for both
slots, so the timers never mount.

Tests: the store-level cases are re-split into occluding and non-occluding
sets, and an AppLayout-level `describe` mounts the real layout so the rule
sits in its true position — asserting that under approval and sudo the rule
is still rendered AND its clock advances (1m 0s to 1m 30s), that a floating
model picker suppresses the clocks with the rule at the top, and that the
same picker leaves them armed with the rule at the bottom.

+ * Occluding (included here):
+ *
+ * - `widget` — the modal widget slot renders at viewport level
+ *   (`ActiveWidgetSlot`, `sdk/host.tsx:209`, outside the ComposerPane
+ *   subtree) so it can anchor the full-screen absolute `Overlay`
+ *   (`components/overlay.tsx`) against the whole terminal.
+ * - The FloatingOverlays set — `modelPicker`, `pager`, `petPicker`,
+ *   `sessions`, `skillsHub`, `pluginsHub` — but ONLY when the rule sits at
+ *   the top.  That panel is `position="absolute" bottom="100%"` inside

+ * - The PromptZone flow states — `approval`, `billing`, `subscription`,

+ *   push content down, they do not cover it.  The rule stays on screen and
+ *   its clock must keep running.
+ * - `agents` and `journey`.  They unmount the entire ComposerPane subtree
+ *   (`appLayout.tsx:553`), so `StatusRule` unmounts with it and React's own
+ *   effect cleanup clears the intervals.  Gating on them would be dead code.
+ * - `ambient` — a glanceable in-flow dock that reserves its own rows.
+ * - Composer completions.  They share the FloatingOverlays grid and do
+ *   occlude, but they are a render prop rather than store state and they
+ *   change on every keystroke; re-arming a 1s interval per character would
+ *   restart the countdown each time and starve the tick outright — strictly
+ *   worse than the churn this gate removes.

Subject: [PATCH 027/311] refactor(ui-tui): single source for the
 floating-panel kind set
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Review follow-up: $isStatusRuleOccluded and FloatingOverlays each
enumerated the same six overlay kinds — adding a 7th floating panel
required updating both or the timer gate silently missed it. Extracted
hasFloatingPanel as the shared predicate (completions stays local to
FloatingOverlays; it deliberately never occludes the status rule).
Full ui-tui suite green (1487 tests).

Subject: [PATCH 028/311] fix(compression): overflow handlers pass
 overhead-aware token size to LCM recovery (issue 441)
MIME-Version: 1.0

Root fix (Option A) for design-session "Context compression exhausted" crashes. The three
compression-retry handlers after an API overflow/413/long-context error (conversation_loop.py
~4229/4488/4747) passed the tool-BLIND messages-only estimate (approx_tokens) to _compress_context,
so hermes-lcm's forced-overflow recovery armed on the message count and missed overflows driven by
tool-schema/system overhead. Now they pass estimate_request_tokens_rough(api_messages, tools=...)
— the same overhead-aware estimator already used at :4580 — so recovery arms on the TRUE request
size; LCM's _overflow_recovery_assembly_cap self-subtracts the overhead so the full request fits.

Empirically validated on real failed session 6dddf1a67b76 (LCM engine, floor=24000/cap=248000):
observed 256,359 >= 248,000 -> arms; recovery 231,313->208,559 msg-tokens -> full request
233,605 < 272,000 FITS. Prior messages-only path did NOT arm (231K < 248K) and crashed.

Durable copy: ~/.hermes/local-patches/optionA-overflow-overhead-aware.patch (survives hermes update
reset). Upstream PR pending. classify_api_error call at :3667 intentionally unchanged (not recovery).

Subject: [PATCH 029/311] fix(compression): route overhead-aware tokens in
 post-tool compress + add recovery-path tests
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Post-tool compression path passed context_compressor.last_prompt_tokens (0 in the no-usage
fallback) to _compress_context instead of the overhead-aware _real_tokens computed just above
— same tool-blind bug as the overflow handlers (upstream PR #77169 review, teknium1). Also adds
production-path regression tests asserting the 413, context-overflow (two wordings), and
Anthropic long-context recovery handlers pass estimate_request_tokens_rough(..., tools=...)
(sentinel-patched) to _compress_context.

+"""Regression tests: overflow recovery handlers must pass overhead-aware token estimates.
+
+PR fix (LCM issue 441): 413, context-overflow, and long-context-tier recovery handlers
+were passing a messages-only token estimate to _compress_context instead of the
+overhead-aware estimate_request_tokens_rough(api_messages, tools=agent.tools or None),
+which includes tool schemas and system prompt overhead.
+
+These tests assert that each recovery handler:
+1. Calls estimate_request_tokens_rough with a non-None `tools` argument.
+2. Passes the resulting value as approx_tokens to _compress_context.
+
+The sentinel pattern (return_value=987654) makes the assertion unambiguous: if
+approx_tokens==987654 the overhead-aware path was taken; any other value means the
+handler used a different (likely messages-only) estimate.

Subject: [PATCH 030/311] fix(matrix): fallback to homeserver query for room
 encryption detection (#71067)

_CryptoStateStore.get_encryption_info only consulted mautrix's in-memory
MemoryStateStore, which has no record of m.room.encryption for rooms the
bot joined in the past (the raw-sync path never feeds those state events
through set_encryption_info). On a fresh crypto store this returns None
for all previously-joined rooms, so OlmMachine reports them as unencrypted,
never tracks peer devices, and silently drops all inbound messages.

Fix: pass the mautrix Client into _CryptoStateStore so get_encryption_info
can fall back to a live GET /_matrix/client/v3/rooms/{room_id}/state/
m.room.encryption query when the in-memory store returns None. The result
is cached back via set_encryption_info so subsequent lookups (and
OlmMachine device tracking) hit the fast path.

Subject: [PATCH 031/311] fix(matrix): reset Olm crypto store when the access
 token's device ID changes
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The crypto store is keyed by Matrix user ID, not device ID, so swapping in
a new access token (which mints a new device_id) silently inherits the
previous device's Olm account. That account's identity keys can never be
published under the new device ID, and the pickle key embeds the old
device ID anyway — the result is stale-key mismatches and cross-signing
signatures the homeserver refuses to replace, degrading E2EE in ways that
are hard to diagnose (peers silently withhold room keys).

_reset_crypto_store_if_device_changed() compares the store's persisted
device ID against the live one at connect time and wipes the store on
mismatch, so a fresh Olm account is generated for the new device instead
of reusing stale key material.

Subject: [PATCH 032/311] fix(matrix): let the token's own device win over a
 stale MATRIX_DEVICE_ID
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

connect() resolved client.device_id as `self._device_id or resolved_device_id`,
so a configured MATRIX_DEVICE_ID masked the live whoami() device. With
persisted A, configured A and a rotated token reporting B, the reset
compared A to A and never fired — exactly the token-rotation case this PR
claims to handle.

An access token is bound to one device and the homeserver only accepts key
uploads for that device, so a configured value naming a different one
cannot work. The live whoami() device now wins on conflict and logs an
error naming both. The configured value is still preferred when whoami()
reports no device.

Adds a connect()-level regression for persisted A + configured A +
whoami B, and corrects test_connect_uses_configured_device_id_over_whoami,
whose stated premise this inverts.

Subject: [PATCH 033/311] fix(matrix): migrate crypto store when the Olm pickle
 key changes
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The Olm account pickle key is derived from the account ID plus the
configured device ID (acct:device_id). If the crypto store's account was
created before MATRIX_DEVICE_ID was set — e.g. the very first password
login, where the device ID is only known after connecting — it gets
pickled under "<acct>:default". Setting MATRIX_DEVICE_ID afterwards (a
reasonable thing to do once you know the device ID you want to pin)
changes the derived pickle key, and every subsequent unpickle attempt
fails with BAD_ACCOUNT_KEY. In optional-E2EE mode that failure is
swallowed and encryption silently stays disabled instead of surfacing an
actionable error.

_migrate_legacy_crypto_pickle() detects the BAD_ACCOUNT_KEY failure,
tries the known legacy pickle keys, and re-pickles the account (plus
every stored olm/megolm session — sessions share the same pickle key, so
migrating only the account would leave them unreadable on the next
decrypt and silently break key sharing with peers) under the current
key. It only reports failure when no known key can unpickle the
account, with a log message pointing at what changed.

Subject: [PATCH 034/311] fix(matrix): commit the migrated account only after
 the session sweep
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The account was written under the new pickle key before sessions were
re-pickled. The account is effectively the migration's commit marker —
once it reads under the current key, the fast path short-circuits every
later startup — so a sweep that errored or was interrupted left the
remaining legacy-key sessions stranded permanently with no retry.

Sweep first, commit the account last, and return False on sweep failure
so the migration is retried on the next start.

Also corrects the unreadable-row log: it claimed rows were being dropped
while no DELETE was ever issued. Such rows are left in place (already
unusable; deleting crypto material on a guess is not worth it) and the
message now says so.

Adds session-sweep coverage, which was previously absent: rows rewritten
under the current key, rows already current left alone, unreadable rows
left in place, and a failed sweep that leaves the account uncommitted.
The existing migration test now fakes the olm C-extension so the suite
no longer requires libolm.

Subject: [PATCH 035/311] fix(matrix): pickle key from resolved device ID, skip
 migration after reset, cache enc info
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Follow-up fixes for the combined Matrix crypto salvage (#71073,
#71543, #71547):

1. Construct _pickle_key from client.device_id (resolved from whoami)
   instead of self._device_id (the configured value). Without this, when
   #71543 makes the token's real device win over a stale
   MATRIX_DEVICE_ID, the pickle key is built from the stale value and
   the Olm account is stored under a key that can never be looked up
   again — perpetuating the same decryption failure the PRs aim to fix.

2. Skip _migrate_legacy_crypto_pickle when the store was just deleted
   by _reset_crypto_store_if_device_changed — there is no account to
   migrate. Also check the migration return value and log a warning on
   failure instead of proceeding to olm.load() which fails with a
   cryptic BAD_ACCOUNT_KEY.

3. Add a local dict cache (_enc_info_cache) to _CryptoStateStore so the
   homeserver fallback in get_encryption_info() does not make a network
   round-trip on every is_encrypted() call. MemoryStateStore does not
   implement set_encryption_info, so the existing cache-back is a no-op.

4. Log homeserver encryption-info query failures at DEBUG level instead
   of silently returning None (which would cause OlmMachine to treat an
   encrypted room as unencrypted).

5. Update _CryptoStateStore docstring to mention the homeserver fallback.

Subject: [PATCH 036/311] fix(whatsapp): guard bridge reconnect against hangs
 and unhandled rejections

startSocket() awaits useMultiFileAuthState() and fetchLatestBaileysVersion()
before it creates a socket or registers event handlers, and the close handler
re-entered it via a bare setTimeout(startSocket, ...). That leaves two
unrecoverable failure modes on a reconnect:

- a rejection is an unhandled promise rejection (fatal on modern Node)
- a hang leaves the bridge permanently disconnected with nothing left to
  retry, while its HTTP server keeps answering 503 to the gateway

The second mode was observed in the field: fetchLatestBaileysVersion() is a
plain fetch to raw.githubusercontent.com with no AbortSignal, and after a
stream:error 503 disconnect the bridge logged 'Reconnecting in 3s...' once
and then sat silent and disconnected for 27+ hours until manually restarted.

Fix, as two pure helpers in bridge_helpers.js (keeping bridge.js side-effect
free to test):

- createReconnectScheduler(): every (re)connect entry point now catches a
  failed startSocket() and reschedules it instead of dying or going silent
- createVersionResolver(): bounds the version fetch with a 15s timeout and
  falls back to the last known-good version (or the Baileys default before
  first success) instead of pending forever

Subject: [PATCH 038/311] fix(cron): stop lifecycle guard false-positives and
 crashes on .py/binary scripts

The gateway lifecycle guard (cron/lifecycle_guard.py) applied shell-style
tokenization and script-reference resolution to non-shell content, with two
regressions:

#77131 - every .py cron script using pathlib division was hard-blocked:
  Path.home() / ".hermes" / ".env" tokenizes the bare "/" operator as an
  executable path, which resolves to the filesystem root; the regular-file
  check then fails closed as unsafe. Since Python runs under the
  interpreter, never through a POSIX shell, the shell-script reference walk
  is a false-positive generator on Python sources. check_gateway_lifecycle
  now skips the walk for *.py scripts (the direct command regex still scans
  the full text), and _iter_referenced_shell_scripts skips pure-separator
  tokens.

#76762 - terminal commands invoking a binary by absolute path (e.g.
  /usr/bin/python3) crashed the guard with ValueError: embedded null byte:
  the walk read the binary's bytes, decoded them as text, and re-tokenized
  machine code; the recursion then hit Path.resolve() on a NUL-bearing
  path while only OSError was caught. _read_referenced_script now skips
  NUL-containing files (binaries are not referenced shell scripts) and
  resolve() tolerates ValueError.

Shell scripts (.sh/.bash/.zsh) keep the full deep scan; literal lifecycle
commands in .py scripts are still blocked by the direct regex. New tests
cover all four behaviors.

Subject: [PATCH 039/311] fix: check NUL bytes before size limit in
 _read_referenced_script
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

On Linux, /usr/bin/python3 is >1MB, so the size check fired before
the NUL check could run — the binary was returned as unsafe=True
(blocked) instead of (None, False) (skip). Reorder: read the bounded
chunk first, check for NUL bytes (binary → skip), then check size
(oversized text → fail closed).

Wrap the masked-link destination in angle brackets so Discord does not
unfurl an OG-preview embed under every tool progress bubble. quote()
percent-encodes any <> inside the URL itself, so the wrapper cannot be

Subject: [PATCH 046/311] perf(tts): pipeline sync per-sentence synthesis with
 playback
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The universal sync fallback in stream_tts_to_speaker ran strictly serially
per sentence — synthesize, play, and only then start synthesizing the next
sentence — so every sentence boundary added a full synthesis-time of dead
air. Chunked streamers (elevenlabs/openai/gemini/xai) already avoid this;
every other provider (edge, piper, plugin providers) paid it on each reply
in voice mode and the wake-word loop.

_SyncSentencePipeline overlaps the two: one single-threaded synthesis
worker (sentences stay FIFO; providers never see concurrent calls from
this loop — same effective concurrency as before) feeds one playback
worker through a small bounded queue, so sentence n+1 synthesizes while
sentence n plays. Lookahead is bounded (backpressure + at most a couple of
temp files), stop_event short-circuits both stages, synthesis failures are
isolated per sentence, temp files are always unlinked, and the finally
block flushes the pipeline BEFORE tts_done_event fires so continuous voice
mode never reopens the mic over its own voice. synthesize/play are
resolved late so existing monkeypatch-based tests work unchanged.

Measured with a real local model provider (OmniVoice plugin, Apple
Silicon), same 3-sentence reply, playback simulated at the produced clips'
true durations, best-of-2 interleaved runs under identical load:

                     serial   pipelined
  time to first word  10.8s        4.4s
  mid-reply dead air  11.2s        1.8s   (second gap: 0.03s)
  full reply wall     33.2s       17.0s

Tests: 4 new (timestamp-proven overlap, order + per-sentence failure
isolation, stop skips queued playback, temp-file hygiene); the existing

Subject: [PATCH 047/311] fix(tui-gateway): merge agent output on model-switch
 history_version mismatch (#76870)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

When a model switch occurs mid-turn, `_append_model_switch_marker()`
appends a marker to session history and increments `history_version`.
The turn completion guard then sees `current_version != history_version`
and discards all agent output — producing empty assistant messages in
the session DB.

Detect when the only history mutation during the turn was one or more
model-switch markers.  In that case, merge the agent's new messages
into the current history (which now contains the marker) instead of
discarding them.  Genuine desyncs (undo/compress/retry) still surface
the warning as before.

Fixes #76870

Subject: [PATCH 048/311] fix: content-based diff for model-switch marker merge
 (#76870)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The original PR #77274 used positional slicing (current_history[len(history):])
to detect the model-switch-only mutation.  But _append_model_switch_marker
strips prior markers in-place before appending the new one, so when a prior
marker existed (every switch after the first in a session), the net length
delta is zero and the slice produces an empty list — the merge path is dead
code for the common case.

Replace with a content-based diff: strip markers from both the turn-start
snapshot and the current history, then check that the non-marker content is
identical.  This correctly handles the strip-and-replace behavior.

Also guard against auto-compression making result["messages"] shorter than
the turn-start history — use the full result as the base when that happens.

Added test covering both no-prior-marker and prior-marker cases.

Subject: [PATCH 051/311] test: move the redelivery event-loop test to the
 class that has its helpers

The sweep-path test parametrizes over _runner/_adapter, which live on
TestGatewayRedeliverySweep; main later added
TestUnconnectedPlatformKeepsItsBudget at the cherry-pick anchor point and
the test landed in that class, where the helpers don't exist
(AttributeError x2). Placement-only move.

Subject: [PATCH 052/311] test: raise blocking-probe timeouts for loaded CI
 runners

CI slices failed the offload tests with 0.5s witness timeouts: on a
loaded shared runner the event loop thread can take >0.5s to get
scheduled even when NOT blocked, making the probe report a false
positive. A genuinely blocked loop can never set the progress event at
any timeout (the witness coroutine can't run at all), so 5s only
absorbs scheduler flake without weakening the invariant. Mutation
re-verified: reverting the offload still fails all 4 tests.

Subject: [PATCH 053/311] test: wait for ledger-wrapped sends in drain
 assertions
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Two consumer tests assumed a send completes synchronously within the
handler turn: the continuation-drain test polled on handler-call count
then immediately asserted on adapter.sent, and the split-brain heal
test drained with bare zero-delay yields. With ledger calls hopping to
worker threads around each send, the reply can land microseconds after
those checks. Poll for the actual sends with a bounded 2s window —
same invariants, scheduling-robust.

Subject: [PATCH 055/311] perf(tools): compact delegate_task description by
 deduping against param schema

The top-level delegate_task description repeated content the model already
receives through parameter descriptions: the concurrency limit (tasks param),
the full nesting clause (role param), context-passing guidance (goal/context
params), and background semantics (background param). Every API call paid for
the duplication (~4,000 chars).

The description now carries only what exists nowhere else in the schema:
use/don't-use routing (execute_code, cronjob), the no-poll rule, the
non-durability warning, the self-report verification contract with concrete
verbs, the language-passing example, the leaf blocked-tool list, and model
inheritance. 3,963 -> 1,704 chars (~570 tokens saved per API call), and the
top-level text is now static (dynamic limits flow only through the two param
descriptions, which are already rebuilt per get_definitions() call).

A/B benchmark across 4 models (gpt-4o, gpt-4o-mini, claude-haiku-4.5,
llama-3.3-70b) showed the naive compaction in PR #72813 regressed weaker
models on exactly the passages it cut (side-effect verification 8/8->0/8 on
gpt-4o-mini; language passing 3/3->0/3 on haiku-4.5). This version keeps
those benchmark-sensitive hooks verbatim.

Tests pin the contracts at keyword level (not prose-literal) plus a size
ceiling, and verify dynamic limits still reach the model via the tasks/role
param descriptions.

Refs #72737, supersedes the delegate_task half of PR #72813.

Subject: [PATCH 056/311] perf(tools): restore benchmark-sensitive phrasing in
 compacted description

Round-2 A/B (gpt-4o-mini, 6 reps) showed two passages could not survive
paraphrase: the DO-NOT-USE list needs the arrow-list shape with the
'no reasoning needed' qualifier (prose form regressed mechanical-work
routing 6/6->1/6), and the self-report rule needs the concrete
'claiming uploaded successfully may be wrong' framing (without it,
side-effect verification regressed 6/6->2/6). With both restored:
30/42 vs 30/42 on gpt-4o-mini and intent-parity on claude-haiku-4.5.
Final size: 1,900 chars (from 3,963).

Subject: [PATCH 057/311] chore: sync uv.lock with nemo-relay android marker

The pyproject.toml change in this branch added an `'android' not in
platform_release` guard to the nemo-relay marker but left uv.lock
carrying the old marker, so the lockfile no longer matched the
manifest. Every CI job that installs dependencies via
`uv sync --locked` failed before running a single test: all 8 Python
test slices, e2e, both Docker image builds, and Desktop E2E, plus the
blocking `uv lock --check`.

Regenerated with uv 0.9.28 to match the version pinned in
uv-lockfile-check.yml and tests.yml. Newer uv (0.12.x) additionally
rewrites the exclude-newer header and drops python_full_version
markers from several packages, which is unrelated churn.

Subject: [PATCH 058/311] fix(approval): stop treating newlines inside quoted
 arguments as command starts

A raw newline in the _CMDPOS start-position class made ANY multi-line
quoted argument look like a command boundary, so hermes send message
bodies, multi-line git commit -m messages, and heredoc text that merely
mentioned dangerous command names tripped the unconditional hardline
blocklist and could not run at all.

Mask newlines inside single/double quotes (detection-only, mirroring the
quote tracking in _iter_shell_command_starts) before building detection
variants. Real threats keep blocking: unquoted newlines stay command
separators, command substitutions inside quotes still anchor, and
_mark_command_starts still re-inserts newlines at genuine quote-aware
command starts. Masking runs on the RAW command before normalization,
which strips escapes and would otherwise corrupt quote state.

Regression tests cover both directions: multi-line quoted data passes
(hermes send, git commit -m, heredocs); bare/chained/substituted
shutdown-class and rm-floor commands still block.

Subject: [PATCH 059/311] fix(cron): retain completed one-shot jobs instead of
 deleting them on completion
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

mark_job_run popped a finite one-shot from jobs.json the moment its
repeat limit was reached and returned early — discarding the
last_status / last_error / last_delivery_error it had just written.
Every finished one-shot vanished from `cronjob action=list` with no
inspectable record, and a delivery failure (agent succeeded, platform
send failed) was silently thrown away with it.

Changes:
- mark_job_run now retires a limit-reached one-shot as a terminal
  record (state="completed", enabled=False, next_run_at=None) —
  mirroring the existing next_run_at-is-None terminal branch — so the
  final status and any delivery error persist and surface in the
  cronjob tool's list output (which already emits last_delivery_error
  and defaults to include_disabled=True).
- claim_dispatch's stale-job cleanup marks already-ran jobs completed
  instead of popping them; genuinely wedged claims (last_run_at never
  written) are still removed with the operator-visible diagnostic.
- Retention sweep in the due scan prunes completed one-shot records
  older than cron.completed_retention_days (default 7; non-positive
  disables) so jobs.json cannot grow unboundedly. Recurring jobs and
  non-terminal one-shots are never candidates.

Tests: completion retains record + delivery error, list surfaces it,
completed jobs never re-dispatch, sweep prunes old / keeps recent /
ignores recurring / honors the disable knob; recurring lifecycle
unchanged.

Subject: [PATCH 065/311] perf(desktop): skip store update when pet metadata is
 unchanged
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

mergePetInfoMeta now returns the same object reference when all fields
match, and callers skip setPetInfo on reference equality. Without this,
every 15s poll and window-focus refetch fired a nanostores set with a
new-allocated object, triggering a React re-render of FloatingPet even
when nothing changed — a regression from the old samePetRevision guard
which returned without calling setPetInfo.

Subject: [PATCH 067/311] fix(gateway): let Desktop omit duplicate transcripts
 on session resume

Salvage of #69926: omit_messages support ported from the PR's
tui_gateway/server.py base onto the post-split methods_session.py
layout. When a Desktop client passes omit_messages=true on
session.resume / session.activate, the RPC returns messages: [] with
messages_omitted: true and an accurate message_count, skipping the
potentially multi-megabyte compression-lineage serialization over the
WebSocket; Desktop hydrates the transcript via the authenticated REST
route in parallel.

The PR's bundled cron-outputs endpoint and codex quiet-timeout bump
were dropped from this salvage as unrelated (invited back separately).

Subject: [PATCH 069/311] test: expect omit_messages in the tile-delegate
 resume call shape

Two more call-shape-pinning tests (cold tile resume, default-profile
resume) assert session.resume's exact params; the delegate passes
omit_messages: true like every other Desktop resume call site.
Swept all 5 desktop test files that reference session.resume/activate:
380 of 381 files green (the one failure is a pre-existing locale-
dependent number-grouping test that fails identically on clean main).

helpers). Cache the filtered catalog at module level with a short TTL
so repeated picker opens do not pay a TLS handshake each time.

Fold-fixes on top of the original patch:
- key the cache by api_key so a mid-process credential swap never
  serves the previous account's catalog
- use time.monotonic() so wall-clock adjustments cannot extend the TTL
- deep-copy on store/serve so callers cannot mutate cached entries
- tests updated to patch _urlopen_model_catalog_request (main routes
  catalog fetches through open_credentialed_url now), plus TTL-expiry
  and credential-change coverage

Extracted from #40276.

Subject: [PATCH 071/311] fix(session-search): strip ANSI from recalled
 messages

Recalled session messages can carry raw ANSI escape sequences (e.g.
archived terminal output), which then re-enter the model's context.
Strip them in _shape_message before content is truncated/returned,
reusing tools.ansi_strip.strip_ansi.

Re-applied onto current main (the original hunk predates the
max_content_len truncation in _shape_message; stripping happens on the
raw content before truncation so escape bytes never count against the
budget). Extracted from #40276.

Subject: [PATCH 072/311] fix(tools): allow Unicode letters in workdir
 validation

The workdir allowlist regex was ASCII-only, so perfectly normal
non-ASCII workdirs (Chinese Obsidian vault paths, accented dirnames)
were rejected with 'disallowed character'. Replace the regex with a
per-character check that accepts Unicode letters/digits (str.isalnum)
plus the same safe ASCII punctuation set, while still rejecting shell
metacharacters, control characters (newlines/tabs), and NUL.

Salvaged from PR #54314.

Subject: [PATCH 073/311] fix(tools): allocate snapshot temp paths with mktemp
 instead of $BASHPID
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Extracted from #54314 (@flag0x369), re-derived onto current main: macOS
ships bash 3.2 as /bin/bash, which lacks $BASHPID entirely — the
variable expands to empty string, collapsing every concurrent writer's
'unique' temp path onto the same file (torn snapshot writes under
concurrency). mktemp allocates per-writer unique paths portably.
Live-verified: /bin/bash -c 'echo $BASHPID' prints empty on this box.

Subject: [PATCH 075/311] fix(lazy-deps): skip the install ladder on
 package-manager installs

Salvage of #48637 (Fixes #48628). On a NixOS-style install the venv's
site-packages lives in the read-only store, so ensure()'s
uv -> pip -> ensurepip ladder spends ~15s bootstrapping ensurepip only
to fail against a target it can never write. Fail fast with an
actionable message pointing at the system package manager.

Retargeted onto current main (the PR's base predates the durable-target
subsystem by ~8.1K commits) with two corrections to the original:

- Gate on _lazy_install_target() is None. The container deployment sets
  HERMES_MANAGED=true AND HERMES_LAZY_INSTALL_TARGET (a writable
  volume); the original guard would have blocked installs that path
  legitimately satisfies, breaking the NixOS-container mode.
- Reason string starts with 'unsupported ' because
  refresh_active_features classifies FeatureUnavailable by that prefix;
  the original wording made 'hermes update' report a hard failure
  instead of a skip.

Placed after _unsupported_feature_reason so a platform-specific reason
(more actionable) wins, and so ensure() agrees with
refresh_active_features, which pre-checks that same function.

Subject: [PATCH 076/311] fix(anthropic): drop whitespace-only text blocks
 reaching the Messages API
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Root cause: two independent bugs in convert_messages_to_anthropic()
(agent/anthropic_adapter.py), the final conversion step before every
Anthropic messages.create() call, both producing HTTP 400 "text content
blocks must contain non-whitespace text":

1. _ensure_leading_user_turn() synthesized a filler user turn with
   content [{"type": "text", "text": " "}] (a single space) whenever the
   built payload didn't start with role=user (e.g. after context
   compaction leaves a leading assistant summary). The space is itself
   whitespace-only, so the guard traded a "leading assistant turn" 400
   for the "text content blocks" 400 it now hits. Fixed to reuse the
   existing non-blank _EMPTY_TEXT_PLACEHOLDER ("(empty)").

2. _convert_user_message() filtered blank text blocks from list-type
   user content with an all-or-nothing check:
   all(blank for b in blocks if b.type == "text"). This is vacuously
   true when a message has zero text-type blocks (silently destroying
   valid non-text blocks like images/documents it never inspected), and
   false as soon as any single text block is non-blank — which let a
   *sibling* blank text block sit untouched next to valid content and
   reach Anthropic as-is. Replaced with per-block filtering (mirroring
   the assistant-side logic already in _convert_assistant_message),
   preserving all non-blank/non-text blocks and relocating any
   cache_control marker carried by a dropped block.

Also added _scrub_blank_text_blocks(), a final defense-in-depth pass run
as the last step of convert_messages_to_anthropic() (after every other
transform, including nested tool_result content lists) so a blank text
block from any current or future producer never reaches the wire. It
logs only structural metadata (message index, role, content location,
block index/type) — never message text, tool arguments, tokens, or
credentials.

An earlier local patch to sanitize_api_messages() (agent_runtime_
helpers.py) attempted to fix this by rewriting blank assistant content
before the OpenAI->Anthropic conversion step, but the real leaks were
introduced downstream of that sanitizer, inside the Anthropic-specific
converter itself — the patch never touched the actual defect and has
been fully reverted (agent_runtime_helpers.py is back to its committed
state; verified via `git diff` showing no changes).

Verified against a real Telegram message end-to-end: the gateway no
longer produces the "text content blocks must contain non-whitespace
text" error on a fresh conversation turn.

Testing:
- 9 new end-to-end regression tests in test_anthropic_adapter.py
  (TestFinalPayloadHasNoBlankTextBlocks) covering content="",
  content="   ", content=[{"type":"text","text":""}], mixed blank+valid
  text, blank text next to a valid tool block, an assistant tool-call
  message with blank content, the leading-synthesized-user-turn case,
  and a blank text block nested inside a tool_result's own content list.
- Fixed one pre-existing test that had asserted the broken " " filler
  behavior as correct.
- Full tests/agent/ + tests/run_agent/ suite (4671 tests) run against
  both the patched tree and a stashed pre-fix baseline: identical 148
  pre-existing failures in both runs (unrelated subsystems — codex
  app-server integration, credential-pool interrupt handling, OpenAI
  client lifecycle), zero failures unique to either side.

Subject: [PATCH 077/311] refactor: dedup _convert_user_message to call
 _fix_blank_text_blocks_in_list

_convert_user_message hand-inlined the same blank-text-filter +
cache_control-relocation + placeholder-fallback logic that
_fix_blank_text_blocks_in_list (added in the cherry-picked commit)
implements as a reusable helper. Replace the inline copy with a call
to the helper, eliminating ~35 lines of duplication.

Follow-up fix on top of PR #77134 by @pooyan6.

Subject: [PATCH 078/311] fix: exclude DeepSeek from OpenCode caching path to
 prevent HTTP 400

OpenCode Zen's relay rejects the Anthropic-style content block format
that cache markers produce (content becomes a block array instead of a
plain string), causing HTTP 400 with "content must be string, not block
array" for DeepSeek models.

Reverts the DeepSeek addition from commit 6b6435a874 while preserving
the Qwen/Alibaba caching path which continues to work.

Fixes #77217

Subject: [PATCH 081/311] feat(mcp): lazy server startup from schema cache
 (design from #56832)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Wires the fingerprint-keyed schema cache (previous commit, @Vansh5632's
design from #56832) into the startup path, re-derived onto main's
current connect machinery:

- register_mcp_servers: servers with mcp_servers.<name>.lazy=true whose
  config fingerprint matches a valid cache entry register tools from
  cache WITHOUT spawning; miss/stale falls back to eager connect.
- First tool use routes through _ensure_lazy_server_connected, which
  composes with the connect cooldown (#50394) and _server_connecting
  dedup rather than duplicating the connect path.
- resource/prompt utility handlers (list_resources/get_prompt) also
  connect-on-first-use — closes the gap flagged in the original
  sweeper review.
- Write-through: a live connect refreshes the cache entry.

Config gate is per-server, default OFF, matching the
idle_timeout_seconds key pattern. 24 lazy/cache tests + 440 mcp-wide
green; mutation-checked (cache-read disabled -> registration test
fails; connect bypassed -> 3 first-use tests fail).

Subject: [PATCH 082/311] polish(mcp): simplify-pass folds on the lazy-startup
 salvage

Five review findings folded:
- schema cache writes via utils.atomic_json_write (fsync; was bare
  tmp+replace), file moved to cache/mcp_schema_cache.json with 0o600
  (sibling precedent: registry discovery cache)
- phantom-tool reconciliation: after a lazy server's first-use connect,
  cached tools the live server no longer offers are deregistered (were
  permanent registry ghosts burning circuit-breaker strikes on every
  'Unknown tool' round-trip); stale fingerprint logged
- cache-load path now runs _scan_mcp_description like the eager path
  (cache file is user-writable JSON; defense-in-depth)
- write-through skips the disk rewrite when the entry is unchanged
  (a flapping stdio server was rewriting byte-identical JSON per
  revival)
- _lazy_server_fingerprints no longer write-only dead state (consumed
  by the reconciliation logging)

444 mcp tests green (440 pre-fold + 4 new guards); phantom-dereg and
write-skip mutation-checked.

Subject: [PATCH 083/311] fix(stt): thread confidence thresholds into
 faster-whisper's own gate (#74178)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

build_local_transcribe_kwargs read stt.local.no_speech_prob_threshold /
stt.local.logprob_threshold only for Hermes' post-filter
(_is_hallucinated_segment). faster-whisper's model.transcribe() never
received them, so its internal defaults (no_speech_threshold=0.6,
log_prob_threshold=-1.0) always applied and silently dropped
low-confidence segments before they reached the post-filter — making
those config knobs dead for the first gate.

Non-English speech decodes at a lower avg_logprob, so the English-tuned
defaults discard whole utterances (empty transcript despite correct
capture and language detection). Map the same config values through to
model.transcribe() so both gates stay in sync and the knobs work.
Defaults are unchanged, so behavior is identical unless a user tunes them.

Fixes #74178

Subject: [PATCH 085/311] fix(credential_pool): check copilot suppression
 before token exchange
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The copilot branch of _seed_from_singletons ran the suppression gate
_after get_copilot_api_token(), which retries the network exchange 3x
with backoff (~13s worst case). A source the user already suppressed
(hermes auth remove copilot gh_cli) still burned the full exchange dead
time on every pool load — model picker open, /model, agent startup —
only to have the entry discarded afterwards.

Move the _is_suppressed() gate ahead of the network call, matching the
early-gate pattern every other singleton branch uses. Suppressed copilot
sources now skip the exchange entirely. Measured: model.options payload
build drops from ~13s to ~0.2-0.4s for a user with copilot suppressed.

Add regression test test_load_pool_skips_exchange_for_suppressed_copilot
asserting the exchange is never invoked for a suppressed source.

Subject: [PATCH 086/311] perf(credential_pool): skip gh subprocess when all
 copilot sources suppressed
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The all-sources suppression gate now runs before resolve_copilot_token(),
which shells out to `gh auth token` (~30ms) on every pool load. A user
who suppressed every copilot source (hermes auth remove copilot gh_cli
suppresses gh_cli + all env variants) still paid the subprocess spawn on
every load — model picker open, /model, agent startup.

Enumerate the same source space credential_sources._remove_copilot_gh
suppresses and bail before any work when all are suppressed. Measured:
model.options payload build drops from ~0.46s to ~0.26s cold for an
all-suppressed user; resolve_copilot_token() is no longer called at all.

Subject: [PATCH 087/311] fix(credential_pool): classify copilot sources by
 exact match

Review fold on the #76341 salvage: the substring test ('gh' in
source.lower()) classified GH_TOKEN and GITHUB_TOKEN as gh_cli, so a
user's env-var-specific suppression was silently bypassed (and
suppressing gh_cli silently dropped env tokens). Pre-existing bug on
main, but the PR's early gate makes the classification decide whether
the exchange runs at all. Match resolve_copilot_token's exact
'gh auth token' sentinel instead.

Adds 3 regression tests: env-var suppression gates the exchange,
gh_cli suppression doesn't swallow env tokens, all-sources suppression
skips the resolve subprocess entirely. Also corrects the ~13s comment
(actual worst case ~35s: 3x10s timeouts + 4.5s backoff).

Subject: [PATCH 093/311] fix(platforms/line): fix broken import of
 non-existent config functions
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

_adapter_config_interactive() imported get_env_var and set_env_var from
hermes_cli.config, but these do not exist — the actual functions are
get_env_value and save_env_value. This caused an ImportError at runtime,
breaking the entire LINE platform adapter setup.

Pain before: Any user who ran the LINE adapter setup function would get:
    ImportError: cannot import name 'get_env_var' from 'hermes_cli.config'

Fix: Import the correct functions with aliased local names:
    from hermes_cli.config import get_env_value as _get_env, save_env_value as _set_env

Also fixed an indentation bug introduced during the fix: the 'if value: _set_env()'
block was incorrectly nested inside the except clause.

Subject: [PATCH 096/311] fix(agent): jittered, interrupt-aware backoff for
 empty-response retries

Empty content retries previously fired back-to-back with no delay,
wasting up to 3 rapid API calls, and could not be cancelled mid-wait.
Apply the same jittered_backoff() already used for rate-limit and
API-error retries, sleeping in small increments so a user interrupt
aborts the wait instead of blocking until it elapses.

Fixes #35230

Subject: [PATCH 100/311] feat(gateway): add opt-in 'latency' runtime footer
 field
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The runtime footer (`/footer`) shows what model ran and how full the context
is, but not how long the turn took. On a messaging platform there is no
progress bar and no shell timer — a turn that took 4 seconds and one that took
four minutes produce visually identical replies. Users comparing models,
providers, or reasoning levels have no at-a-glance signal for the one
dimension they most often care about, and "was that slow or did I imagine it?"
is unanswerable after the fact.

Adds a `latency` field to the existing footer machinery, rendering the
wall-clock duration of the agent run: `<1s`, `22s`, `1m05s`.

`gateway/run.py` measures with `time.monotonic()` immediately around the
`self._run_agent(...)` await in `_handle_message_with_agent` — the same
function that already builds the footer, so the value is the user-perceived
turn duration (monotonic, so it is immune to wall-clock/NTP adjustment).

`latency` is deliberately NOT in `_DEFAULT_FIELDS`. It is opt-in via
`display.runtime_footer.fields`. Every existing footer — and every footer a
user has today without touching config — renders byte-identically.

This is enforced by tests, not just asserted:

- `test_latency_not_in_default_fields` pins the default tuple.
- `test_resolve_footer_config_default_fields_exclude_latency` pins what
  config resolution produces for an untouched config.
- `test_default_footer_renders_byte_identically` pins five exact output
  strings for default-config renders **while supplying `turn_seconds`** —
  proving that even when the caller measures timing, a default-configured
  footer does not show it.
- `test_default_build_footer_line_ignores_turn_seconds` asserts
  `build_footer_line(...) == build_footer_line(..., turn_seconds=125.0)`
  under default fields.

Adding `latency` to `_DEFAULT_FIELDS` fails 11 of these tests.

No new config surface (reuses `display.runtime_footer.fields`), no new env
vars, no new core tool, no new model-facing schema. One new module-private
helper (`_format_latency`), one new keyword argument threaded through the two
existing footer functions, and 3 lines in `gateway/run.py`.

`turn_seconds` defaults to `None` and the field is skipped when it is `None`
or negative, so any call site that does not measure timing keeps working
unchanged.

`tests/gateway/test_runtime_footer.py` (+185): `_format_latency` boundary
table (sub-second, rounding at 59.4/59.6, the `m{:02d}s` zero-pad, 60m), the
render/skip/opt-in matrix, field-order placement, `build_footer_line`
threading, and the byte-stability block above.

RED-proved by mutation — each of these breaks tests:
- `latency` added to `_DEFAULT_FIELDS` → 11 failures
- dropping the `turn_seconds is not None and >= 0` guard → 2 failures
- `{sec:02d}` → `{sec}` → 6 failures
- `build_footer_line` not threading `turn_seconds` → 1 failure

51 passed in `tests/gateway/test_runtime_footer.py`; 54 passed across the
footer blast radius. `ruff check` clean.

Subject: [PATCH 102/311] feat(transport): imply prompt_cache_key capability
 for api.openai.com
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Review follow-up on the #56798 salvage: the gate shipped fully dormant
(no provider profile sets supports_prompt_cache_key, no production
caller passes it, and no plain 'openai' profile exists to set it on) —
AGENTS.md rejects dead code wired in without E2E proof.

Activate the one endpoint where the field is first-class: exact-host
api.openai.com (OpenAI documents prompt_cache_key; GPT-5.6+ docs
recommend it for cache routing). Deliberately NOT substring matching —
Azure/OpenAI-compat endpoints may reject unknown fields and stay
opt-in via the flag. 4 new tests (imply + 3 spoof/proxy/Azure
negatives); mutation-checked (substring-weakened host check fails the
spoof tests).

already runs inside a turn whose config was loaded once into

 update (#39267)

Re-derivation of PR #39399 onto current main: pass --prefer-offline to
the web-UI workspace install (both silent and verbose arms of
_install_web_deps) and to the update-time Node dependency refresh in
_update_node_dependencies, so npm reuses its local cache instead of
re-fetching metadata. Test expectations updated to match, mirroring the
PR's own test-update commit.

Subject: [PATCH 105/311] perf(cron): skip config load on idle scheduler ticks
 (idea from #33612)

Re-derivation of #33612 by @LeonSGP43 onto the rewritten scheduler (the
original is 10,692 commits behind; its tick() no longer exists in that
shape, so this is a fresh minimal fix crediting the PR's idea).

The gateway's built-in ticker calls tick(verbose=False) every 60s. The
idle early-return was gated on 'verbose and not due_jobs', so idle
GATEWAY ticks fell through to load_config() + worker-pool resolution
every minute. Return early on ANY idle tick; keep the post-tick MCP
orphan sweep (main intentionally reaps orphaned stdio children on idle
ticks).

3 new tests; mutation-checked (restoring the verbose-gated guard fails
the config-skip test). 66 scheduler tests green.

Subject: [PATCH 106/311] fix(feishu): defer the lark_oapi import off the
 startup path

Salvage of #57657, ported onto the plugin layout (the adapter moved
from gateway/platforms/feishu.py to plugins/platforms/feishu/adapter.py
since the PR's base). lark_oapi takes seconds to import and holds the
GIL doing it; the module-level import made every gateway boot pay that
cost even with Feishu unconfigured.

- _load_lark_oapi() with double-checked locking binds the SDK globals
  on first use; connect() and _standalone_send() call it via
  asyncio.to_thread so the loop never blocks on the import.
- probe_bot() also calls _load_lark_oapi() (sync context) so the SDK
  probe path is preserved rather than silently degrading to the HTTP
  fallback before a first connect.
- check_feishu_requirements() is install-only and no longer rebinds
  globals; test_feishu.py gets a setUpModule that binds them eagerly
  for tests that inject fake clients.

Includes the dedicated lazy-import test file (check-does-not-import,
connect-loads-on-worker-thread).

Subject: [PATCH 107/311] test: bind lark SDK globals session-wide, not
 per-file

CI exposed the whole class: feishu tests across MANY files (thread
routing, text batching, sdk executor, ...) inject a mock _client and
skip connect(), so the deferred import leaves the request-builder
globals None. Replace the single-file setUpModule with a session-scoped
autouse conftest fixture that binds the globals once when lark_oapi is
installed; when it isn't, the affected tests already skip via their own
skipUnless guards. Full tests/gateway run: zero failures beyond main's
pre-existing baseline (sorted failure-diff).

Subject: [PATCH 108/311] fix(feishu): test SDK globals by None-ness, not
 globals() membership
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The no-SDK fallback guards check '"Name" in globals()' — correct on
main where a failed module-level import leaves those names undefined,
but the deferred-import port pre-binds every SDK name to None, so the
guard was always true and the fallback paths called .builder() on None
(AttributeError) wherever lark_oapi isn't installed. Local runs passed
because lark IS installed here; CI's default env has no feishu extra.
Rewrote all 14 guards to 'is not None', which is correct under both
conditions. Verified by simulating CI with a lark-blocking meta_path
hook: 74 passed, 18 skipped (the skipUnless set), zero failures.

Subject: [PATCH 110/311] perf: replace COUNT(*) with LIMIT-based existence
 checks
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Two places were using SELECT COUNT(*) when they only needed a boolean:
- has_any_sessions() called session_count() > 1 (full table scan)
- delete_session() used SELECT COUNT(*) WHERE id=? (full matching scan)

Fix:
- Add session_count_ge(n) to SessionDB — short-circuits via
  SELECT 1 FROM sessions LIMIT n, returns bool
- has_any_sessions() uses session_count_ge(2) instead of session_count() > 1
- delete_session() uses SELECT 1 ... LIMIT 1 with fetchone() is None
- Add tests for session_count_ge

Subject: [PATCH 111/311] fix(state): take the connection lock in
 session_count_ge + document archived semantics

Review fold-ins on top of #56768 (@Skywind5487):
- session_count_ge ran its query without self._lock, unlike every
  sibling counter on SessionDB (session_count, session_count_by_source).
- Document the deliberate semantics change: session_count() defaults to
  archived = 0, which is both the expensive part (full index scan,
  measured 543us vs 4us on 20k sessions) and wrong for the only caller
  (has_any_sessions asks 'has this install ever had sessions' -- an
  archived session is still a created one).

Subject: [PATCH 112/311] perf(state): index assistant tool-call rows for
 Insights queries

InsightsEngine._get_tool_usage and _get_skill_usage scan messages for
role='assistant' AND tool_calls IS NOT NULL, but no index aligns with
that predicate, so SQLite scans the full messages table on a large
state.db. Add a partial index over exactly those rows.

role and tool_calls are base columns in the messages table, so the index
lives in SCHEMA_SQL (created on both fresh and existing databases via the
executescript on every open) rather than DEFERRED_INDEX_SQL.

Adds schema regression coverage (fresh + reopened DB, plan uses the index)
and an Insights regression test proving tool/skill output is identical with
and without the index present.

Fixes #67341

Subject: [PATCH 113/311] perf(insights): pin partial index on assistant
 tool-call queries
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Review follow-up (#67341): on a freshly initialized state.db (before
ANALYZE has run) the source-filtered branches of _get_tool_usage /
_get_skill_usage did not select idx_messages_assistant_calls_by_session
— the optimizer drove from idx_sessions_source_id and probed each
session's messages via idx_messages_session_active, scanning non
tool-call rows. Pin the index with INDEXED BY on all four fixed-predicate
branches so the plan is deterministic for both the unfiltered and
source-filtered scopes without depending on statistics.

Safe because the index is declared in SCHEMA_SQL (created by every
read-write SessionDB._init_schema) and every InsightsEngine caller opens
a read-write SessionDB; read-only attachments (which skip schema init)
are never used for insights.

Extract the four queries into class constants and add tests: query-plan
coverage for both scopes without ANALYZE, row-level equivalence between
pinned and un-pinned forms, and an assertion that INDEXED BY fails loudly
if the index is absent.

Subject: [PATCH 114/311] fix(insights): fall back to unpinned queries when the
 partial index is absent

The INDEXED BY pin is a hard dependency -- SQLite raises 'no such
index' when the named index is missing. That happens in production:
the web dashboard's usage analytics (_get_usage_analytics,
_get_models_analytics) open state.db read_only=True, which skips
_init_schema, so a DB last written by a pre-index version has no
idx_messages_assistant_calls_by_session and every insights call
crashes with OperationalError (reproduced E2E).

Probe sqlite_master once in __init__ and strip the pin from the four
prepared statements when absent -- identical rows, optimizer-chosen
plan, no crash. Replaces the change-detector test that froze the
crash as intended behavior with a fallback-equivalence test.

 attribute loop

Simplify-pass fold: the four copy-pasted .replace blocks meant a\nfifth pinned statement could forget its strip line — a hard 'no such\nindex' crash on read-only DBs, the exact bug the fallback prevents.\nLoop over the attribute names instead.

Subject: [PATCH 116/311] perf(state): batch compression-tip row fetch in
 list_sessions_rich
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

list_sessions_rich()'s compression-root projection called
_get_session_rich_row() once per root — a separate single-row query per
compression root on every session-list render. Resolve every tip id
first, then fetch all tip rows in one WHERE id IN (...) query via the
new _get_session_rich_rows_batch().

_get_session_rich_row() is now a thin wrapper over the batch method, so
the enriched SELECT (preview + last_active) lives in exactly one place —
future column changes (e.g. #42196's include_system_prompt) only touch
one query.

get_compression_tip()'s chain walk is untouched; it's a genuine
per-session graph walk with branch/delegate-exclusion and race handling,
and batching it safely is out of scope here.

Subject: [PATCH 117/311] test(state): guard compact_rows threading through
 batched tip-row fetch

Adds two regression tests for the #59077 batch: (1) _get_session_rich_rows_batch(compact_rows=True) uses the schema-derived compact projection (no system_prompt, git_branch/git_repo_root kept); (2) list_sessions_rich(compact_rows=True) threads compact_rows through the compression-tip projection call site. Mutation-checked: hardcoding compact_rows=False at the call site fails test 2.

Subject: [PATCH 119/311] fix(yuanbao): clear
 _processing_msg_ids/_processing_msg_texts after each message
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

_dispatch_inbound_event() writes session_key → msg_id/raw_text into
_processing_msg_ids and _processing_msg_texts so RecallGuardMiddleware
can find and interrupt the currently-processing message.  These entries
were never removed after a message finished processing, causing both
dicts to grow unboundedly — one persistent entry per unique session key
for the lifetime of the bot.

Fix: clear both entries in the _process_message_background() finally
block, after super() returns.  The guard compares the stored msg_id
against event.message_id before popping: a concurrent pending message
may have already overwritten the entry in _dispatch_inbound_event while
we were running, in which case the drain task owns it and we must not
clear it.  When msg_id is absent (nothing was written at dispatch time)
the pop is a safe no-op.

Note: _msg_content_cache already bounds itself to 200 entries at the
same write site; _processing_msg_ids and _processing_msg_texts had no
such bound.

Subject: [PATCH 120/311] fix(yuanbao): evict stale entries from _member_cache
 on TTL expiry

_build_msg_body_with_mentions() checks the TTL of each _member_cache
entry and returns an empty member list when the entry is stale, but
never removes the entry from the dict.  Over time every group_code the
bot has ever queried accumulates a permanent entry, retaining the full
member list (potentially thousands of records per group) until
disconnect().

Fix: delete the stale entry at the point it is detected as expired.
The next call to get_group_member_list_raw() for the same group will
repopulate the cache with fresh data as before.

Symmetric with the existing TTL pattern in MessageDeduplicator, which
evicts on access.

Subject: [PATCH 121/311] fix(yuanbao): pop tracking entries only for truthy
 matching msg_id + regression tests

Follow-up on the salvaged pair: the original guard's `not msg_id` arm let an
id-less internal/synthetic event erase a tracking entry a concurrently-queued
id-bearing message's drain task still needs for recall matching (id-less
events never write entries in _dispatch_inbound_event, so they must never
pop). Tests cover: normal cleanup, id-less non-erasure, overwritten-entry
ownership handoff, TTL eviction + fresh-entry survival.

Subject: [PATCH 123/311] perf(zai): parallelize endpoint detection probes

Z.AI has separate billing for general vs coding plans and global vs
China endpoints. On startup, detect_zai_endpoint() probes up to 4
endpoints sequentially with 8s timeout each, taking 8-9 seconds when
the first endpoints return non-200 (rate limited) before a working one
is found.

Replace the sequential loop with concurrent.futures.ThreadPoolExecutor
to probe all 4 endpoints in parallel. Results are returned in
ZAI_ENDPOINTS priority order so the preference chain is preserved.

Benchmark on macOS M4 Max, Python 3.11, Hermes v0.8.0:
  Before: 8.8s (sequential: global=0.9s/429, cn=1.6s/429,
           coding-global=4.3s/200, coding-cn=2.0s/200)
  After:  ~4.5s (single round-trip, bounded by slowest endpoint)

Subject: [PATCH 124/311] test(zai): cover parallel-probe contracts + restore
 candidate-model loop

Rebase fold: the original PR predates ZAI_ENDPOINTS growing per-endpoint
probe_models lists; the parallel worker now preserves that candidate-model
fallback loop (was: scalar model). Tests (both mutation-checked):
- candidate-model fallback within one endpoint worker
- ZAI_ENDPOINTS priority order wins over completion order
- all-fail returns None

Subject: [PATCH 125/311] perf(zai): early-exit when the highest-priority
 endpoint wins (simplify finding)

The as_completed drain + `with` join made the parallel version WORSE than
sequential main in the common case (first endpoint succeeds fast, others
slow/unreachable): main returned at first success, the parallel version
waited for every straggler. Now: after each completion, walk endpoints in
priority order and return as soon as a success is unbeatable (all
higher-priority probes already finished); pool uses shutdown(wait=False) so
losers drain in the background. Mutation-checked: removing the early exit
makes the new timing test fail (8.2s vs <1.5s).

Subject: [PATCH 127/311] fix(minimax-oauth): read streamed error bodies inside
 the client context + real-transport tests
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Follow-ups on the salvaged bounded-read fix:
- refresh flow: the non-200 branch reads a STREAMED body, which fails
  (ReadError/StreamClosed) once the httpx.Client context has exited —
  moved inside the context. Repro + regression test use a real socket
  server (MockTransport buffers in memory and cannot catch this).
- truncation guard: >limit bodies end with ...[truncated] (mutation-checked
  against the is_stream_consumed fallback).
- test mocks now model the streamed-read surface (is_stream_consumed,
  iter_bytes, client.send) so non-200 paths exercise the real bounded read.

Subject: [PATCH 132/311] fix: skip memory prefetch on trivial user prompts
 (greetings)

Salvage of PR #25350 (commits 88ffede2d + 2b848a0b2 + 3136dc63a, squashed
and ported): the run_agent.py prefetch site the PR gated has since moved
into agent/turn_context.py's build_turn_context(), so the trivial-query
gate lands there instead.

- Gate the per-turn memory_manager.prefetch_all() on a trivial-prompt
  check so greetings/acknowledgements ('hi!', 'thanks', 'ok') no longer
  block the turn on provider network round-trips or inject stale context.
- Extend honcho's _TRIVIAL_PROMPT_RE with greetings and a trailing
  punctuation class so 'hey!' / 'hello.' classify as trivial.
- Add honcho classifier tests for greeting forms.

Subject: [PATCH 134/311] refactor(memory): single shared trivial-prompt
 classifier + gate tests
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Rebase fold on the salvaged gate:
- is_trivial_prompt/TRIVIAL_PROMPT_RE move to agent/memory_provider (the
  ABC both the core gate and providers already import) — one source of
  truth; honcho's _TRIVIAL_PROMPT_RE now aliases it, turn_context and the
  queue_prefetch_all warm path (a sibling site main grew after the PR's
  base) both use it
- tests: gate tests at the prefetch call site (mutation-checked), shared
  classifier tests incl. prefix-collision guards (k8s/yolo/note/supper),
  and honcho dialectic-machinery tests re-driven with a substantive prompt
  ("hello" became trivial by design — those tests exercise thread cadence,
  not the classifier)

Subject: [PATCH 135/311] refactor(honcho): delegate _is_trivial_prompt wholly
 to the shared classifier

Simplify-pass finding: sharing only the REGEX left the wrapper logic
(empty/strip/slash checks) duplicated, half-defeating the no-drift goal.
The classmethod now calls agent/memory_provider.is_trivial_prompt directly;
_TRIVIAL_PROMPT_RE stays as a class attr for backward compatibility with
any external referents.

Subject: [PATCH 136/311] fix(desktop): measure adaptive stream flush through
 the deferred commit frame

scheduleDeltaFlush's adaptive floor is driven by lastFlushCostRef, but
runFlush only timed flushQueuedDeltas(), the synchronous store write.
While a session streams, syncSessionStateToView defers the $messages
publish (React commit + Streamdown re-parse) to its own rAF, so the
measured cost stayed near zero and the floor collapsed to the fixed
33ms path no matter how expensive the real commit was.

runFlush now records the write cost as a fallback, then extends the
measurement through a rAF registered after the view-sync one: it runs
in the same frame right after the deferred commit, and the rAF
timestamp marks frame start so only in-frame work is counted, not the
vsync wait. A stale callback from before a newer flush is ignored, and
a hidden renderer that never fires rAF keeps the write-cost fallback.

Subject: [PATCH 140/311] fix(desktop): full-jitter backoff on gateway WS
 reconnect loops

All three desktop reconnect loops (primary gateway boot, secondary
multi-profile gateway pool, plugin event socket) used bare exponential
backoff with no jitter. After a gateway restart every disconnected
client redials on the exact same schedule, so the reconnect attempts
land in lockstep instead of spreading out -- a burst that can starve
the gateway's file descriptors while it's still coming back up.

Add reconnect-backoff.ts implementing AWS-style full-jitter backoff
(random delay in [0, min(cap, base * 2^attempt))) and wire it into all
three call sites in place of their local Math.min/2**attempt math.
Manual reconnect paths already reset the attempt counter and bypass
the timer entirely -- unchanged.

Subject: [PATCH 141/311] fix(desktop): escalate gateway reconnect on elapsed
 time, not attempt count
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

With the full-jitter backoff (300ms base) six attempts can elapse in ~9s,
so the old RECONNECT_ESCALATE_AFTER=6 attempt threshold raised the
recoverable boot error during a brief post-boot blip — breaking the
'a remote that drops post-boot keeps looping with NO boot.error' contract.
Escalate after RECONNECT_ESCALATE_AFTER_MS (45s, matching the old
deterministic 1->15s ladder's calibration) elapsed since the first failed
reconnect of the episode. Reset on clean open, manual/wake reconnect, and
soft switch, preserving the reset-on-success path.

Extracted from #59352 by @rerdi92 (the rest of that PR — a month-stale icons.ts rewrite and a chunk-size warning-ceiling bump — is superseded/masking and was not salvaged).

Re-derive of PR #38470 on today's main (its target file desktop-controller.tsx no longer exists after the contrib/ refactor; the three surviving ideas are applied at their new homes):

- incremental-external-store-runtime: the dep-less setAdapter effect ran every render; gate on [runtime, store] — behavior-preserving because __internal_setAdapter early-exits on identical store.
- ChatView is now memo()d, and session-tile hoists its inline arrow props to useCallbacks/module constants so the memo actually holds.
- Render-count regression test (mocked Thread) proves an unrelated parent re-render no longer re-renders the chat shell.

Credit: idea and original implementation by @hdd69 in #38470.

Subject: [PATCH 145/311] perf(curator): trim dead tool-schema from the LLM
 review fork

The curator LLM review loop (_run_llm_review) built its AIAgent without
enabled_toolsets, so it advertised the full default catalog (~30 tools plus the
context_engine lcm_* family) on every call. The fork uses only four tools, fixed
by its own system prompt, with no dispatch path to the rest, so ~26 tool schemas
shipped on every request as dead weight: ~7K input tokens per call on a loop that
makes 50-100 calls per consolidation pass.

Restrict the fork to enabled_toolsets=["skills", "terminal"], the same tools the
prompt already names. Behavior-neutral: the prompt held the model to these tools
and nothing routed calls to the others. Mirrors the background_review fork
(background_review.py:788-794). Call-site only; AIAgent already forwards the kwarg.

Adds test_review_fork_restricts_toolsets_to_skills_and_terminal (captures the
constructor kwarg) and test_review_fork_toolset_surface_is_skills_plus_terminal
(pins the resolved surface).

Subject: [PATCH 146/311] fix(desktop): keep a mid-turn reply on screen when
 its session is reopened
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Switching sessions while a turn streams (or right as it completes) could
leave the assistant reply missing until restart. Resume merges stored
history with the gateway's `inflight` projection, whose assistant row is
text-only and often an empty `assistant-stream-${sessionId}` shell; both
reconcile paths then dropped the local pending row that held the only copy
of the streamed text, reasoning and tool calls.

A shared pair of guards replaces the ad-hoc comparisons at all three sites.
`localPendingSupersedes` accepts the cached row only when it is the same
reply further along — an empty shell it has content for, or text it strictly
extends — so a longer unrelated row can no longer hijack an ordinal or reuse
a stream id, and a retained `inflight.error` snapshot is never mistaken for
an empty shell. `withAuthoritativeTurnState` then takes content from the
renderer while liveness, row id and reactions stay the backend's call, so a
settled shell cannot leave a finished reply spinning.

Subject: [PATCH 147/311] fix(desktop): stop a finished reply rendering twice
 after history catches up
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

When a turn's reply commits under its own id, the settled local
`assistant-stream-*` row shifts one assistant ordinal earlier, so ordinal
pairing finds nothing at its slot and re-appends it — the same answer twice.

Drop a settled stream row only when the authoritative transcript already
carries that exact text. Keying `isPendingAssistant` on the explicit pending
flag alone would also have fixed this, but it discards the sibling case in
the same report: a reply that finished locally before the gateway committed
it, where the local row is the only copy that exists.

Subject: [PATCH 149/311] refactor(desktop): hoist the reference-line matcher;
 drop dead textWithoutImageRefs
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Follow-up to #77653: textWithoutReferenceLines built a fresh /g RegExp per call and hand-managed lastIndex — but it runs on both sides of every message comparison in the reconcile loops. An anchored non-global regex has no shared-lastIndex hazard and can be hoisted to module scope. Also removes textWithoutImageRefs, whose last production consumer #77653 replaced (kept IMAGE_REF_LINE_RE for extractImageRefs), and retargets its now-stale comment.

Subject: [PATCH 151/311] fix(desktop): scope inflight dump suppression to the
 live turn tail

Only skip/graft structure for the current live assistant (stream id,
pending, or after the latest user), not completed historical tool rows.
Require live-tail identity for same-turn structure carry. Align journal
overlay with strict answer-text extension.

Addresses review + CI on #76744.

Subject: [PATCH 152/311] fix(desktop): require structure-bearing row for
 live-tail same-turn carry

Structure-only same-turn carry used (live(previous) || live(message)), so a
new live text-only assistant at a compression-rewritten ordinal could inherit
reasoning/tool parts from an unrelated historical structured row.

Require the structure-bearing cached row itself to be live-tail (pending /
assistant-stream-* / interim). Add regressions for non-extending live dump
carry and the compression graft rejection.

Addresses salvage path on #76744 / #76444.

Subject: [PATCH 153/311] refactor(desktop): one live-tail vocabulary for
 transcript reconciliation

Two fixes landed overlapping helpers on the same statement: the mid-turn
reply guard grew `isLiveProjectionRow` / `hasStreamedContent`, while the
inflight-dump guard grew `isLiveTailRow` / `hasStructuralParts`. Two
definitions of "is this row live" and "does it carry content" in one
function is how the next change silently reshapes one of them.

Collapse to a single module-level pair. `isLiveTailRow` now covers pending,
stream ids, inflight projections and sealed interim rows, so the reply guard
also stops treating an interim row as committed history; `hasStreamedContent`
is defined in terms of `hasStructuralParts`. Both text-extension checks route
through `isStrictAnswerTextExtension` rather than a bare `startsWith`.

Also hoists the live-tail lookup out of an inline IIFE and fixes the lint
warnings it carried.

Subject: [PATCH 156/311] fix(dashboard): warm cold check_fn verdicts with a
 background probe

On dashboard-only sessions nothing else executes check_fn warmers (they
live only in the tool-schema build), so the hub's read-only cache lookup
would report auth_required=False forever. On a cache miss, schedule a
deduplicated daemon-thread probe off the request path; the short hub TTL
surfaces the verdict on the next fetch.

Subject: [PATCH 157/311] fix(desktop): cancel the pending commit-cost
 measurement rAF

Follow-up to #77652: each runFlush registered a fresh requestAnimationFrame and never cancelled it. Chromium parks rAF callbacks for hidden renderers, so a long hidden stream at the 33ms floor accumulates thousands of parked closures that all fire in the first frame on refocus (all but one no-oping through the stale-frame guard). Track the pending handle, cancel it before requesting a new one (only the newest flush's measurement matters), and cancel on unmount.

Subject: [PATCH 160/311] refactor(insights): drop consumer-less
 get_skill_breakdown alias (simplify-pass)

The 2-line alias had zero production consumers (web_server calls
get_usage_breakdown directly). Tests rewired onto the real API; the
contracts they pin are unchanged. Stale test docstring fixed.

Subject: [PATCH 161/311] fix(web): clamp dashboard pagination and
 analytics-days params (#39200 + #74778 salvage)

Re-derivation of aydnOktay's twin clamp PRs onto current main (the
session-list endpoints moved into web_routers/; the analytics endpoints
gained asyncio.to_thread wrappers since the originals):

- limit le=100 on /api/sessions, /api/sessions/search and the
  /api/profiles/sessions fan-out (one unbounded request could drag every
  session row + correlated-subquery preview work out of SQLite, times
  every profile's state.db on the fan-out).
- days ge=1 le=365 on /api/analytics/usage + /api/analytics/models
  (huge or non-positive values force full-history InsightsEngine work or
  inverted windows; the UI only offers 7/30/90 presets).

FastAPI Query bounds reject at the validation layer (422). 8 new tests;
both clamp classes mutation-checked (clamp removed -> its tests fail).

Subject: [PATCH 162/311] fix(clamps): raise profile fan-out limit to le=500
 (simplify-pass finding)

le=100 would 422 real desktop callers: sessions-settings fetches
archived at limit=200, the command palette lists at 200, and the
electron remote-merge over-fetches limit+offset (exceeds 100 at
offset>=81, and its .catch(()=>null) silently drops remote sessions).
Clamp must sit above real client maxima. New test pins limit=200 w/
offset.

Subject: [PATCH 164/311] perf(plugins): seed plugin routes from sessionStorage
 cache for instant render

- Plugin manifests are now cached in sessionStorage on fetch.
- On refresh, plugin routes are registered synchronously from cache, preventing unwanted redirects to /sessions.
- Removes the !pluginsLoading guard from the catch-all route in App.tsx, as plugin routes are now always available on first render.
- Background fetch always updates the cache and routes, so new/removed plugins are reflected after reload.
- Resolves the race condition where plugin pages would redirect to /sessions on hard refresh.

Subject: [PATCH 167/311] fix(plugins): keep loading gate when cached manifests
 include a /chat override

The sessionStorage seed set loading=false whenever any cache existed, which
defeats App.tsx's load-bearing pluginsLoading gate: with a cached manifest
that declares tab.override === "/chat", the persistent ChatPage host must
NOT mount before plugins resolve, or it spawns a PTY and gets yanked when
the override plugin takes over the route.

Seed loading=false from the cache only when no cached manifest overrides
/chat (canSeedLoadedFromCache); manifests are still seeded either way so
plugin routes register synchronously on refresh. Adds focused tests for
the gate, including the /chat-override case.

Subject: [PATCH 168/311] perf(dashboard): serve hashed /assets bundles with
 immutable cache headers
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Every hashed bundle chunk under /assets/ was served with no caching
directives, so each dashboard load re-fetched (or at best revalidated)
every JS/CSS chunk. Those filenames carry a Vite content hash — the
bytes behind a given URL can never change; a rebuild mints new
filenames referenced by a freshly served index.html.

Mark them Cache-Control: public, max-age=31536000, immutable:
- the /assets StaticFiles mount, via a subclass that stamps the header
  on 200s only (404s stay uncached — a rebuild can create the file),
- serve_css, preserving its X-Forwarded-Prefix url() rewrites for
  /fonts/, /fonts-terminal/, /ds-assets/, /assets/.

index.html keeps no-store, no-cache, must-revalidate — it is the
mutable entry point that binds users to the current hashes.

The original PR also added hand-rolled per-request gzip compression of
asset responses; that part is deliberately dropped. This server is a
localhost-default dashboard backend: compressing every response on the
CPU to save loopback bandwidth is a pessimization, and callers that
front it with a real proxy already get compression there.

Salvaged from PR #28543 (idea by @sea-monsters; gzip groups dropped as
described above).

restore_primary_runtime retries the primary every turn once the 60s
transient cooldown clears. For subscription-window limits (Claude
Pro/Max 5h windows, Codex weekly caps) the reset is hours or days away,
so every retry is a guaranteed failure costing two provider switches
and two prompt-cache invalidations per turn.

Add CredentialPool.next_available_at() (earliest reset across exhausted
entries; None when available now or no reset info) and gate the restore
on it: skip while the primary's pool says nobody can serve, restore on
the first turn after the reset elapses. Fail-open: any gate error or
missing reset info falls through to the existing per-turn retry, so
recovery can never be later than today. Cross-provider fallbacks
consult the PRIMARY's pool (not the attached fallback pool), reusing
the loaded pool for the existing rebind to keep auth reads at one per
restore.

 :::info Per-Turn, Not Per-Session
 Fallback is **turn-scoped**: each new user message starts with the primary model restored. If the primary fails mid-turn, fallback activates for that turn only. On the next message, Hermes tries the primary again. Within a single turn, fallback activates at most once — if the fallback also fails, normal error handling takes over (retries, then error message). This prevents cascading failover loops within a turn while giving the primary model a fresh chance every turn.
+
+The per-turn retry is **reset-aware**: when the primary's credentials report a rate-limit reset time that hasn't elapsed yet (subscription windows like Claude Pro/Max's 5-hour blocks or Codex weekly limits report these as hours or days), Hermes skips the doomed retry and stays on the fallback until the reset passes — avoiding two pointless provider switches (and two prompt-cache invalidations) per turn. The moment the reset time elapses, the next turn goes back to the primary automatically. Transient 429s without a reset time keep the existing behavior: a short cooldown, then retry every turn.

Subject: [PATCH 170/311] fix(credential_pool): run next_available_at under the
 pool lock
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Review fold on the #67642 salvage: next_available_at() called
_available_entries() — which prunes DEAD entries, syncs tokens, and
persists — and iterated self._entries with no lock, racing concurrent
select()/rotation exactly as has_available()'s comment warns. Wrap the
method body in self._lock and pin it with a non-blocking-acquire probe
test.

Subject: [PATCH 171/311] fix(credential_pool): defer single-use-token refresh
 outside threading lock

select() and acquire_lease() held self._lock during the entire
_available_entries() loop, which for openai-codex and xai-oauth providers
includes a cross-process file lock (_auth_store_lock) plus OAuth token
refresh HTTP POST.  The lock timeout can exceed 20 seconds, blocking all
credential pool consumers across every gateway thread and subagent.

Collect single-use-token refresh entries under the lock, then execute the
refreshes outside it.  On success the refreshed entry is merged back into
the pool and re-selected.  Non-single-use providers (anthropic, nous)
continue refreshing inside the lock since their refresh is a simple HTTP
POST with no cross-process coordination.

Subject: [PATCH 172/311] fix(credential_pool): serialize deferred-refresh pool
 mutations
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Review folds on the #71775 salvage (dossier findings 1+2):

- self._lock becomes an RLock and the mutation primitives
  (_replace_entry, _persist) are now self-locking, so the deferred
  single-use-token refresh path — which deliberately runs its
  cross-process flock + OAuth network I/O OUTSIDE the pool lock —
  still serializes its pool mutations against concurrent
  select()/rotation. In-lock callers re-acquire reentrantly.
- Dropped _refresh_pending_entries' redundant second _replace_entry:
  _refresh_entry already merges the refreshed entry internally.

Adds tests/agent/test_credential_pool_deferred_refresh.py pinning both
invariants: select() must NOT hold the lock during the refresh window
(the PR's whole point), and the post-refresh mutations MUST contend on
the lock (blocking-thread probe).

Subject: [PATCH 173/311] `hermes sessions optimize-storage` aborts with
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

```
Error: optimization failed: no such table: messages_fts_trigram
No data was lost. Re-run to resume.
```

on any install where the trigram FTS index is legitimately absent. The failure is
deterministic — re-running can never make progress, because the crash happens at the same
point every time — so the database is permanently stuck on the legacy high-footprint FTS
layout with no supported way forward.

Observed on a 5.4 GB production `state.db`. After the fix the same database optimized
successfully and shrank to 3.3 GB.

The trigram index is absent whenever the runtime cannot maintain it. On a SQLite build
without the `trigram` tokenizer, `_ensure_fts_schema()` returns `False`, so `__init__`
leaves `self._trigram_available = False` and no `messages_fts_trigram` table on disk. This
is a **supported degraded runtime**, not damage — CJK/substring search falls back to
`LIKE` and everything else works normally. `_is_fts5_unavailable_error()` and
`_warn_trigram_unavailable()` exist specifically to make this path graceful.

Two code paths write the boundary sweep for the deferred FTS rebuild, and only one of them
respects that flag:

| Function | Trigram `INSERT` guarded? |
|---|---|
| `fts_rebuild_step()` | ✅ `if include_trigram:` where `include_trigram = self._trigram_available` |
| `_fts_rebuild_finish()` | ❌ unconditional |

`_fts_rebuild_finish()` runs the boundary sweep at the *end* of the backfill. Its
unguarded `INSERT INTO messages_fts_trigram …` raises `OperationalError`, which propagates
out of `optimize_fts_storage()` and aborts the entire optimization — *after* the backfill
has already completed. Hence the characteristic output showing 100% progress immediately
before the error:

```
Rebuilding index: 100% (909,671/909,671)
Error: optimization failed: no such table: messages_fts_trigram
```

There is a second, quieter consequence. The teardown phase that reclaims the demoted
`fts_v22_trash_*` shadow tables runs *after* the backfill phase in
`optimize_fts_storage()`. Because the crash happens before teardown is ever reached, those
tables are never emptied or dropped — so the space the migration was supposed to reclaim
stays allocated indefinitely, and the leftover trash tables look (misleadingly) like
evidence of a half-finished migration.

Build a populated v23 database, set the deferred-rebuild markers, then reopen it on a
runtime where `_ensure_fts_schema('messages_fts_trigram', …)` returns `False` (exactly
what a SQLite build without the trigram tokenizer produces) and call
`optimize_fts_storage()`:

```
[precondition] trigram absent, _trigram_available=False, rebuild pending  ✓

RED  ✗ optimize_fts_storage raised OperationalError: no such table: messages_fts_trigram
```

With this patch applied, unchanged harness:

```
     optimize_fts_storage returned {'ok': True, 'vacuumed': None}
GREEN ✓ optimize ok; markers cleared; base FTS 'zebra' -> 200 hits
```

Full harness and transcripts in `TEST-EVIDENCE.md`.

Gate the sweep on `self._trigram_available`, exactly as `fts_rebuild_step()` already does:

```python
include_trigram = self._trigram_available

def _do(conn):
    ...
    if include_trigram:
        conn.execute("INSERT INTO messages_fts_trigram(...) ...")
```

The base `messages_fts` sweep and the marker cleanup are untouched, so the rebuild still
finalizes correctly and the index remains complete for every row it is responsible for.
The fix does not disable or weaken search to dodge the error — the regression tests assert
that base FTS still returns results afterwards.

`TestFtsRebuildFinishWithoutTrigram` in `tests/test_hermes_state.py`:

- `test_rebuild_finish_skips_trigram_when_unavailable` — drives `_fts_rebuild_finish()`
  directly on a trigram-less runtime; asserts it completes, clears both rebuild markers,
  and leaves base FTS searchable.
- `test_optimize_fts_storage_succeeds_without_trigram` — end-to-end through the public
  `optimize_fts_storage()` entry point; asserts `ok=True`, markers cleared, search intact.

Both use the existing `_NoTrigramConnection` helper already in the file. Both fail on
`main` with `no such table: messages_fts_trigram` and pass with this patch.

`tests/test_hermes_state.py` passes in full (463 tests → 465 with these two). `ruff` clean.

This PR is the crash only.

A companion PR narrows `_db_opens_cleanly()` so that
`hermes sessions repair --check-only` stops reporting a write-broken FTS schema as
healthy — the gap that makes this class of problem hard to diagnose in the first place.
The two are independent and can land in either order.

 _available_source_summary
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Simplify-pass finding: _listing_group_label already falls back to 'other' for empty source names, and _classify_source guarantees source_name=='' only when source=='other' — both  legs were dead by construction. Aligns the summary path's grouping with the listing path.

Subject: [PATCH 176/311] fix(credential_pool): unpack the tuple in
 next_available_at's gate
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Cross-PR interaction fix: #77714 (salvage of #71775) changed
_available_entries to return (available, pending_refresh) while #77631
(salvage of #67642) added next_available_at() which still truthiness-
tests the bare return. A non-empty tuple is always truthy — even
([], []) — so the reset-aware gate silently returned None ('no wait
info') for every exhausted pool, disabling the feature #77631 shipped.
Unpack the tuple and test the available list.

Also adapts the lock-probe test for the RLock introduced by #77714
(same-thread non-blocking acquire always succeeds on an RLock; probe
from a helper thread instead).

Subject: [PATCH 180/311] perf(session): route SQLite PRAGMAs through central
 apply_database_pragmas
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Addresses review from @teknium1 on PR #71755:

- Extended apply_database_pragmas() to handle cache_size, mmap_size,
  and temp_store from config.yaml (alongside existing wal_autocheckpoint
  and journal_size_limit). No hardcoded defaults — all values are
  opt-in via config.yaml, avoiding policy conflicts with other PRs.
- Applied to ALL connection types: writer (_connect_and_init),
  read_only cross-profile attach, and WAL per-thread readers
  (_get_read_conn). Previously PRAGMAs only ran on the writer path.
- Removed inline PRAGMAs from _connect_and_init — single source of
  truth in apply_database_pragmas().
- Documented config keys with examples in function docstring.

Subject: [PATCH 182/311] test(session): guard config-gated performance PRAGMAs
 across all connection types
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

E2E guard for the salvaged PR #71755: database.cache_size/mmap_size/
temp_store from config.yaml must reach the writer connection, the
read-only cross-profile attach, and the WAL per-thread reader — and a
default install (no database: keys) must keep byte-identical SQLite
defaults on every connection type. Also covers integer-coercion
rejection of garbage values for the three new keys.

cache_size uses -16000 (not the doc example -2000) because -2000 is
SQLite's compiled-in default and would not discriminate a regression.

Subject: [PATCH 185/311] perf(desktop): pause hidden-pane timers in agents
 view, cron sidebar, and floating pet

Partial pick of the surviving renderer hunks from #75395 (perf commit
6502e441d plus fixup 3fbbc9c1d): gate the 500ms subagent now-ticker and
the cron sidebar 1s ticker/run-poll on usePaneVisible, and skip the
legacy floating-pet poll while the document is hidden. Dropped hunks
(electron/main.ts, vitest.setup.ts/config) intentionally excluded.

Subject: [PATCH 187/311] refactor(desktop): shared pulse beat + fully-gated
 cron peek (simplify folds)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Two findings from the simplify pass on the final trio diff:

- status-pulse: one pause controller + one aligned period timer shared by all StatusPulse instances (ref-counted), instead of N x (document/window/bridge listeners + unsynchronized 5s wakes) — a sidebar can show dozens of pulsing dots. Pause still cancels in-flight animations so the compositor sleeps immediately.
- cron-jobs-section: the runs-peek effect created its interval even while the pane was hidden (callback no-oped but the timer still woke the renderer every 8s/60s per expanded job). Early-return when hidden — visibility is already in the dep array, so becoming visible restarts load + timer.

Subject: [PATCH 188/311] fix(lint): import sort + eslint-disable for
 timer-handle ref clear in effect
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

CI-caught: cron-jobs-section had an extra blank line between sorted imports; use-message-stream's visibility-flush effect assigns flushHandleRef.current=null inside a useEffect (legitimate timer-clear, not an atom mirror) — eslint-disable-next-line per the rule's documented convention.

Subject: [PATCH 189/311] fix(state): narrow FTS UPDATE triggers with AFTER
 UPDATE OF + migration

Retarget #73639 onto the SessionDB mixin split (hermes_state_common /
hermes_state_schema). Fresh installs create UPDATE OF content/tool_*
triggers; existing broad AFTER UPDATE triggers are inspected and
replaced under schema init without an FTS rebuild (WHEN clauses already
guarded content correctness; OF skips non-content status writes that
saturated disk I/O on large state.db).

Tests: tests/test_fts_update_of_narrowing.py (4)

Subject: [PATCH 191/311] fix(state): quarantine CJK when ensure soft-fails
 after OF migration

_ensure_fts_cjk_schema never raises on OperationalError; post-condition
after dropping messages_fts_cjk_update now requires a narrowed UPDATE
trigger or durable fts_cjk_stale + unavailable. Covers the production
soft-fail path the raise-only handler missed.

 trigger migration
MIME-Version: 1.0

Content-Transfer-Encoding: 8bit

Simplify-pass fold: to_drop names come from the literal update_names\nallowlist via IN binding, so the [A-Za-z0-9_]+ fullmatch could never\nfail — and if it somehow did, its `continue` would miscount (the\nskipped trigger stayed in len(to_drop)/the log while CREATE TRIGGER\nIF NOT EXISTS silently kept the broad variant). Delete the guard and\nits function-local re import; keep the invariant as a comment.

Subject: [PATCH 193/311] fix(security): reject always-blocked OpenViking
 endpoints

## Summary
- Normalize OpenViking endpoints through `is_always_blocked_url` and fall back to the default local endpoint when poisoned.
- Keep intentional loopback / LAN self-host working.
- Add focused unit tests.

## Salvage / credit
Memory-provider endpoint floor sibling of RetainDB/Supermemory always-blocked hardening (avoids over-broad #4984-style private-IP bans).

(cherry picked from commit 8fa607d0aedb8c5fca398d7f112b1b25ade54fa2)

Subject: [PATCH 195/311] fix(openviking): don't spawn a second server onto a
 live port
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

`_start_local_openviking_server()` spawned `openviking-server`
unconditionally. Both callers — `initialize()` and the runtime
unreachable handler — reach it from a health probe, and that probe can
time out client-side while the server is up and serving. The spawned
process then loses the data-directory lock and exits immediately with
`DataDirectoryLocked`; because the probe keeps timing out, the cycle
repeats every cooldown window (~5 min observed).

The existing 30s `_failed_refresh` cooldown paces the loop but cannot
stop it, since it expires while the underlying condition persists.

Probe the target host:port before spawning and treat an occupied port as
already-started. This guards both call sites at their single convergence
point. The probe deliberately tests only that a listener owns the port —
enough to know a second server would lose the lock — and says nothing
about that listener's health.

The parse/probe now precedes the PATH lookup, so a reachable server is
reported as running even when `openviking-server` is not on PATH.

Fixes #74846

Subject: [PATCH 196/311] fix(openviking): drop stale "disabled for this Hermes
 run" warnings
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The provider used to disable OpenViking permanently when the server was
unreachable. That was fixed: `_ensure_client()` now reconnects lazily,
with a 30s cooldown gate in `_ensure_client_locked`.

Only one of the seven user-facing warnings was updated to match. The
other six still told the user memory was "disabled for this Hermes run",
which is no longer true — every one of those paths is retried on the next
access. A user who reads the old message has no reason to retry, which is
very likely how #5721 ("never recovers") came to be filed against
behaviour that already recovers.

All six sites were traced to confirm none is terminal for the run: the
`initialize()`-time and waiter-thread failures never arm `_failed_refresh`
(only line 2439 does), so they retry on the very next access with no
cooldown at all.

The replacement wording deliberately omits the "(after cooldown)"
parenthetical used at the already-correct site — that detail is only
accurate where `_failed_refresh` was just armed. The neutral phrasing is
true at all six.

Also promotes two clause separators to periods to avoid "…; …disabled;"
collisions.

Subject: [PATCH 197/311] fix(openviking): re-arm the commit guard after
 in-place compression
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

`_committed_session_ids` is a permanent per-sid latch, and
`_session_needs_commit` checks it before the turn counter by design — a
racing sync_turn can re-increment `_turn_count` after commit+reset, so
the guard must win to stop a double-commit.

That is correct for a session being left behind. It is wrong for one
that keeps its id. `compress_context()` commits before rewriting the
transcript in both modes, and with `compression.in_place: true` (the
default) `on_session_switch` receives the same id and does not rotate.
The latch then rejects every later commit for a still-live session — the
next compression, /new, normal session end, startup recovery — so every
post-compression turn is silently never extracted.

Rotation mode is unaffected because a fresh child id is minted and
starts clean, which is what confirms the latch's intent was only ever to
dedupe the departing id.

Clear the latch when compression completes without rotation. Turns
arriving after that point are genuinely new, and this is a defined
moment rather than a race. The rotation path is untouched, so the old
id stays latched and its _finalize_session_async still dedupes against
the compression commit.

Fixes #74695

Subject: [PATCH 198/311] test(openviking): cover the compression lifecycle,
 not a hand-set latch
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Review feedback: the previous test called _mark_session_committed
directly, so it verified the guard's behavior but not the wiring that
sets it — a future break in the commit_memory_session -> same-id
compression-boundary path would not be caught.

Add a lifecycle regression that drives the real sequence: on_session_end
commits through the actual path, on_session_switch(same id,
reason="compression") crosses the boundary, sync_turn records a genuinely
new turn, and a second on_session_end must produce a second commit POST.

Without the fix it fails showing exactly one commit call, which is the
reported data loss: every turn after the first compression is dropped.
The rotation and /undo tests stay as scope guards.

Subject: [PATCH 199/311] fix(memory): read non-secret provider config from
 config.yaml for OpenViking and RetainDB

OpenViking is_available() only consulted env vars and use_ovcli_config, so an
endpoint saved to config.yaml (e.g. by the Dashboard) reported needs_config;
_resolve_connection_settings() likewise never folded config.yaml's non-secret
fields into its chain. RetainDB initialize() read base_url/project from the
environment only, ignoring the values the Dashboard writes to config.yaml.

Both now resolve non-secret fields as env -> (ovcli ->) config.yaml -> default;
secrets still come from the environment. Adds regression tests for both.

Fixes #68209

Subject: [PATCH 200/311] fix(openviking): read recall settings from
 config.yaml first, env vars as fallback

_recall_config() previously read all settings (recall_limit, score_threshold,
recall_resources, etc.) exclusively from environment variables. This forced
users to store behavioural configuration in .env, violating the Hermes
convention that .env is for secrets only.

The infrastructure to load config.yaml -> memory.openviking was already in
place via _load_hermes_openviking_config(), but _recall_config() never
called it.

Fix: call _load_hermes_openviking_config() and pass its values as the
default parameter to _env_int/_env_float/_env_bool. Env vars still override
config.yaml values, preserving backward compatibility.

Closes #62540

Subject: [PATCH 201/311] test(openviking): cover config.yaml recall settings
 with temp-HERMES_HOME tests
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Add three tests to TestOpenVikingConfigSchema:

1. test_recall_config_reads_from_config_yaml — writes memory.openviking
   settings in config.yaml and verifies _recall_config() consumes them.

2. test_recall_config_env_overrides_config_yaml — writes both config.yaml
   and OPENVIKING_RECALL_* env vars, verifies env takes precedence.

3. test_recall_config_partial_config_yaml — partially populated config.yaml
   falls back to defaults for omitted keys.

All 46 openviking_plugin tests pass (43 existing + 3 new).

(cherry picked from commit b8d7834caf06c6912004333c270faa248eaed4cd)

Subject: [PATCH 206/311] fix(openviking): catch endpoint errors in setup
 validation functions

Review follow-up for salvaged PR #76782. Three setup-wizard
validation functions called _normalize_openviking_url outside their
try/except blocks. Since _normalize_openviking_url now raises
_OpenVikingEndpointError for blocked or malformed endpoints, an
invalid endpoint would crash the wizard instead of returning a
friendly (False, message) tuple.

- _validate_openviking_auth: move _normalize_openviking_url inside try
- _validate_openviking_root_access: same
- _validate_openviking_setup_values: catch _OpenVikingEndpointError explicitly
- Remove dead ternary in _normalize_openviking_url safety check (candidate
  always has http/https scheme by that point)
- Replace redundant float('-inf') < x < float('inf') with math.isfinite()
  in _setting_float; drop the redundant infinity check from _setting_int
  (is_integer() already rejects inf/nan)

Subject: [PATCH 210/311] fix(context): dedupe subdirectory hints by content
 digest and skip backup/vendor dirs

SubdirectoryHintTracker re-injected identical context files whenever the same
AGENTS.md was reachable through more than one path. Symlinked shared
workspaces, hardlinks, and timestamped backup copies all alias a single file,
so a normal session could ship the same 8KB of instructions two or three
times. Nothing deduped it and nothing excluded directories that only ever
hold copies.

Two changes:

* Track a sha256 of every injected hint body. Repeat content is skipped, and
  the working directory's own context file is seeded at construction so the
  copy prompt_builder already loaded at startup is never sent again.
* Skip directories that hold copies rather than authoritative context
  (backups, node_modules, venv, site-packages, .git, .Trash, vendor, caches).
  Screening is relative to working_dir, so a project that legitimately lives
  under vendor/ keeps discovering its own subdirectory hints.

Measured on a real session that touched a symlinked shared workspace:
3 injections / ~24,000 chars before, 1 injection / 8,112 chars after.

14 new tests cover symlink aliasing, byte-identical copies, working-dir
seeding, distinct content still being injected, each excluded directory name,
excluded ancestors, and the working-dir-inside-excluded-name case.

Subject: [PATCH 211/311] perf(state): batch the turn flush into one SQLite
 transaction

Re-derivation of #23254 (@devsart95) on today's flush loop. The turn
flush in _flush_messages_to_session_db wrote one BEGIN IMMEDIATE
transaction per message row; a typical agent turn (user + assistant +
tool results) paid 3-8 transactions -- and, off WAL (the default on
macOS while the WAL-reset guard is active), 3-8 fsyncs -- per turn.

Adds SessionDB.append_messages_batch: same row shape as append_message
(shared _prepare_message_row serializer + _MESSAGE_INSERT_SQL column
list, so the two writers cannot drift), same compression-lock and
compression-closed guards, one aggregated session-counter UPDATE, one
transaction for the whole batch. Row serialization stays outside the
write lock.

The flush loop now collects the turn's new rows and writes them in one
call. All-or-nothing pairs exactly with the persisted-marker stamping:
on failure no rows landed and no markers were stamped, so the next
flush re-writes the whole tail (same recovery contract as before,
minus the partial-prefix case that could double-count).

Measured (same harness, 5-message turn, journal_mode=DELETE,
synchronous=FULL): 2.32ms -> 0.83ms median per turn flush (64% faster,
5 fsyncs -> 1). On WAL the win is smaller but the atomicity fix holds.

Subject: [PATCH 212/311] perf(tui-gateway): batch branch-seed history copies
 (whole-bug-class)

Sibling sites of the per-message flush pattern: both branch-seed
paths (session.branch in methods_session.py and the lazy seed persist
in server.py) copied the parent history row-by-row -- one transaction
per row, and a branch seed can be hundreds of rows. Route both through
SessionDB.append_messages_batch. The server.py path also gains real
atomicity: _branch_seed_persisted assumed every row landed, which the
per-row loop could not guarantee.

nothing (the flush's try/except swallowed the AttributeError). Assert
on the batch payload instead.

Subject: [PATCH 214/311] =?UTF-8?q?refactor(state):=20fold=20simplify=20fi?=
 =?UTF-8?q?ndings=20=E2=80=94=20reuse=20=5Finsert=5Fmessage=5Frows,=20shar?=
 =?UTF-8?q?e=20guards,=20chunk=20seeds?=
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Simplify-pass folds on the #23254 salvage:

- REUSE (HIGH): append_messages_batch now delegates row serialization to
  the pre-existing _insert_message_rows helper (already shared by
  replace_messages / archive_and_compact / portability import) instead
  of adding a third serialization path (_prepare_message_row +
  _MESSAGE_INSERT_SQL are gone). One row-writer for every multi-row
  path; the row-ID return was consumed by no production caller, so the
  batch returns the inserted count.

- QUALITY (HIGH): the compression-lock + compression-closed admission
  guards are extracted into _check_transcript_write_guards, shared by
  append_message and append_messages_batch (previously duplicated 23
  lines that had already needed targeted fixes, #74478). The role-gated
  reasoning filtering is no longer duplicated in run_agent.py — it
  lives at its one site inside _insert_message_rows.

- EFFICIENCY (MEDIUM, measured): unbounded seed copies hold one BEGIN
  IMMEDIATE for seconds (10k rows ~= 2.4s; FTS triggers dominate) and
  monopolize the in-process write lock. append_messages_batch grows a
  chunk_rows param; all seed/copy call sites use chunk_rows=500. Same
  recovery semantics as the old per-row loops, bounded lock holds.

- REUSE (MEDIUM): the two remaining per-row branch-copy loops found by
  the pass (gateway/slash_commands.py /branch, hermes_cli
  cli_commands_mixin.py branch) are converted to chunked batches too
  (AsyncSessionDB's generic to_thread forwarder covers the async site).

Turn-flush benchmark unchanged after the refactor: 2.43 -> 0.87 ms
median per 5-message flush (64% faster).

Subject: [PATCH 215/311] fix(tests): update two more append_message.call_args
 assertions to append_messages_batch
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

CI-caught: test_verification_stop_caching and test_tui_gateway_server::test_native_vision_turn_persists_a_renderable_image_ref both assert on append_message.call_args, but the flush loop now calls append_messages_batch. Same class of test-fake fallout fixed in 5 other files — these two were missed.

Subject: [PATCH 216/311] perf(tui): memoize useSessionLifecycle return (idea
 from #38491)

Re-derivation of #38491 by @stremtec onto current main (the original is
10,119 commits behind; the hook moved into ui-tui/src/app/). The hook
returned a fresh object literal every render, defeating memoization in
useMainApp's consumers; useMemo over the (all-useCallback-stable)
handles makes the return referentially stable.

Dep array covers ALL nine returned handles incl. trimTail (the
re-derivation initially omitted it - stale-closure class).

Subject: [PATCH 218/311] fix(state): route session-resume reads through the
 WAL read-only connection
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

get_messages_as_conversation, get_resume_conversations, and
get_ancestor_display_prefix still took self._lock — the same global
choke point the read-path split (WAL per-thread read-only connections)
was meant to remove from every recall/browse read. These three are the
hottest reads in the file: every session resume across the gateway,
CLI, and ACP adapter goes through one of them, so a resume racing a
burst of concurrent-session writer flushes still convoys behind them
exactly like the fixed paths used to.

_session_lineage_root_to_tip (the lineage walk shared by all three,
plus get_conversation_root) had its own independent self._lock use and
needed the same conversion — without it the outer functions still
blocked on the very first line.

Verified empirically: a reader thread calling all three functions
while another thread holds self._lock blocked for the writer's full
hold duration before the fix, and returned immediately after (SQLite
3.50.4 in this dev venv falls back to journal_mode=DELETE per the
WAL-reset-bug guard, so the requires_wal-marked regression test is
exercised via a local WAL-forced script instead; it still runs and
passes on any runtime where WAL is actually active).

Subject: [PATCH 220/311] fix(model_metadata): rewrite localhost->IPv4 for the
 remaining local probe sites

fetch_endpoint_model_metadata's generic (non-LM-Studio) /models fetch and
its llama.cpp /v1/props context-length follow-up built request URLs
straight from the unrewritten candidate, unlike every other local-probe
site. Both retained the multi-second dual-stack IPv6 connect penalty
that _localhost_to_ipv4() exists to skip (measured on macOS: localhost
32.9ms vs 127.0.0.1 0.1ms on a dead port; ~2s on Windows). normalized
stays the cache key so caching behavior is unchanged; only the outbound
request target is rewritten.

Re-derived from PR #61528 onto current main (original no longer applied
cleanly).

Subject: [PATCH 222/311] perf(cold-start): mitigate ~14s GIL stall during
 backend init (#60800)

Three fixes for the Desktop/TUI cold-start stall where the event loop
is blocked for ~14s between HERMES_BACKEND_READY and the first
prompt (#60800):

1. copilot_auth: skip  subprocess fallback when any
   Copilot env var is explicitly set (even if invalid). The user
   expressed token intent via env var; silently substituting a CLI
   token is surprising and the subprocess adds up to 5s on Windows.

2. tui_gateway/ws: run resolve_skin() via asyncio.to_thread so config
   loading + skin engine init do not block the WS read loop during
   the cold-start RPC burst.

3. web_server: extend _warm_gateway_module to pre-import the heavy
   module chains (auth, copilot_auth, runtime_provider, skin_engine,
   inventory, model_switch) that the first WS connection + RPC burst
   would otherwise import on the loop thread. These trigger .pyc
   compilation and Defender scans on Windows (15-30s per the existing
   comment) and were not covered by the original gateway-only warm.

Tests: 5 new tests in test_cold_start_gil_stall.py + 2 new tests in
test_copilot_auth.py. All 36 copilot_auth tests + 16 ws/web_server
tests pass.

Subject: [PATCH 223/311] test: harden cold-start regression tests + debug-log
 the env-var skip
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Review folds on the #60807 salvage:
- resolve_skin tests are behavioral (thread-ident probe + ready-frame
  wiring check) instead of pure source inspection, per the #72720
  pattern; a source assertion remains as belt-and-braces.
- The warm-list test does REAL imports and checks sys.modules —
  _warm_gateway_module swallows ImportError by design, so the PR's
  tracking-stub test would pass even with a typo'd module name.
- resolve_copilot_token logs a debug line when the env-var
  short-circuit skips the gh-CLI fallback (behavioral change made
  observable).

Subject: [PATCH 224/311] perf(gateway): per-platform skip_context_files to cut
 agent build latency

Salvage of #26860 (hunk 2, ported \u2014 the PR's base predates the current
gateway layout by ~11.9K commits). Messaging platforms can set
gateway.platforms.<key>.skip_context_files: true to skip the
filesystem-heavy context-file discovery (SOUL.md, AGENTS.md,
.cursorrules walks) during AIAgent construction \u2014 10-100x slower
stat()/walk costs on Windows made this a real per-turn tax. Soul
identity is still loaded (single small file), so the persona survives.

The flag participates in _agent_config_signature so toggling it
rebuilds the cached agent instead of silently reusing a prompt built
under the other setting (prompt-cache correctness).

The PR's hunk 1 (mtime-caching the per-turn dotenv reload) was dropped:
df51ad797 mtime-cached load_config/read_raw_config and c2eda92fd
removed the per-turn deepcopies, capturing most of that win; the
function has since gained a multiplex early-return and managed-scope
overlay that the original whole-function skip would have bypassed.

Subject: [PATCH 225/311] fix(relay): route Discord tool-progress into the
 auto-thread, not the parent channel (#77830)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

When a Discord channel message initiates a relay auto-thread, the thread does
not exist at ingest (source.thread_id is None) — the connector creates it on
its FIRST send and auto-threads any outbound carrying the reply anchor. The
final reply carries that anchor, so it lands in the thread. But the
tool-progress / status bubbles (the "Searching the web for..." updates and the
streaming preamble) were sent with _progress_metadata=None and
_progress_reply_to=None: _resolve_progress_thread_id returns None for Discord
(only slack/mattermost get a synthetic thread), so the progress send had no
anchor and the connector posted it FLAT in the parent channel. Result: the
search-status updates leaked outside the thread while the answer threaded
(staging repro 2026-08-02).

The connector now stamps prospective_thread_id on the inbound (the anchor
message id == the id of the thread it will create). Reuse it: when a
relay-delivered Discord channel-initiate carries prospective_thread_id and has
no real thread yet, carry the reply anchor (event_message_id) on both the
progress metadata (reply_to_message_id) and the progress reply_to, so the
connector routes the progress bubble into the SAME auto-thread as the final
reply. Applied to both the tool-progress path (_progress_metadata /
_progress_reply_to) and the status/interim callback path
(_status_thread_metadata). Events already arriving in a real thread, DMs, and
non-relay sources are untouched (guarded on delivered_via_upstream_relay +
prospective_thread_id + not thread_id).

Tests: two new cases in test_run_progress_topics.py — a relay Discord
channel-initiate asserts every progress send carries the anchor (reply_to +
metadata.reply_to_message_id + non_conversational), and an event already in a
real thread asserts the synthetic-anchor path does NOT engage. Full gateway
progress + relay + session suites green (228 passed).

Subject: [PATCH 226/311] fix(agent): stop re-probing endpoints that blackhole
 TCP connects
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Salvage of #71282 (Fixes #71281): a routable-but-dead endpoint (corp
LAN address while off-VPN) blackholes TCP SYNs, so every probe in the
model-metadata waterfall waits out its full connect timeout — 20+
seconds of stall per startup across detect_local_server_type,
fetch_endpoint_model_metadata, and the per-model probes.

A module-level blackhole cache keyed on host:port is populated when
any probe observes a ConnectTimeout (httpx or requests; read timeouts
deliberately excluded — an accepted connection is not a blackhole) and
consulted at the top of each guarded function. 30s TTL: long enough to
collapse one startup burst, short enough that VPN recovery is picked
up without a restart. Guard ordering: blackhole check -> disk L2 ->
HTTP waterfall, and a blackholed leg aborts the remaining legs instead
of letting each stall in turn.

Squash of the PR's two real commits (the branch's merge commits made
it un-rebase-merge-able; content verified identical via merge-tree).

+"""Tests for short-circuiting probes to endpoints that blackhole TCP connects.
+
+A routable-but-dead endpoint (e.g. a corp LAN address while off-VPN) drops SYNs
+without a RST or ICMP error, so each probe waits out its full timeout. Once one
+probe has observed that, the rest must not repeat it.
+
+Covers:
+- _endpoint_blackholed / _note_endpoint_blackholed host:port keying and TTL
+- detect_local_server_type aborting its waterfall on the first connect timeout
+- fetch_endpoint_model_metadata skipping its candidate loop once blackholed
+- _query_ollama_api_show_uncached / _query_local_context_length_uncached
+  honouring and recording the blackhole
+- non-timeout failures (refused, no route) leaving the waterfall untouched

Subject: [PATCH 230/311] fix(discord): leave voice channels before cancelling
 the bot task

`DiscordAdapter.disconnect()` cancelled the bot task before tearing down voice
clients. `leave_voice_channel()` ends in `await vc.disconnect()`, and discord.py
sends a voice state update over the main gateway websocket and then waits for the
voice socket to close. The bot task is the loop running that gateway connection,
so cancelling it first left the handshake with no transport: it could never
complete and blocked until the caller's shutdown timeout fired.

The effect was a fixed ~5s penalty on every shutdown with a voice connection
open, ending in "discord disconnect timed out after 5.0s - forcing continue",
with the voice disconnect abandoned rather than completed.

Measured on a live gateway with a voice connection open in both cases:

  before: timed out after 5.0s, all adapters disconnected at +5.29s
  after:  discord disconnected (0.12s), all adapters disconnected at +0.46s

Moving the voice-cleanup loop above `_cancel_bot_task()` preserves the
zombie-client protection its comment describes: the bot task is still cancelled
before `client.close()`, just after voice teardown rather than before it. Voice
teardown is the one step that still requires a live gateway.

Adds a regression test asserting the ordering. It fails on the previous ordering
at index 1 with `cancel_bot_task != leave_voice_channel:111`.

Fixes #76044

 ### GPT-Image Quality
 
 The `fal-ai/gpt-image-1.5` and `fal-ai/gpt-image-2` request quality is pinned to `medium` (~$0.034–$0.06/image at 1024×1024). We don't expose the `low` / `high` tiers as a user-facing option so that Nous Portal billing stays predictable across all users — the cost spread between tiers is 3–22×. If you want a cheaper option, pick Klein 9B or Z-Image Turbo; if you want higher quality, use Nano Banana Pro or Recraft V4 Pro.

Subject: [PATCH 234/311] fix: exponential backoff for rate-limit fallback
 cooldown
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Replace the fixed 60-second cooldown with exponential backoff:
30min → 1h → 2h → 4h cap.

The counter is reset by restore_primary_runtime on successful
primary-provider recovery, so the backoff is strictly for
consecutive failures within a single degradation window.

Closes #29702

Subject: [PATCH 235/311] fix(backoff): keep 60s first-hit cooldown, escalate
 only on consecutive rate-limits

Review follow-up on the #30223 salvage: the original changed the base
cooldown from 60s to 1800s, benching the primary for 30 minutes on the
FIRST 429 (30x regression in primary-restore latency) and breaking the
existing test_rate_limit_exhaustion_keeps_60s_cooldown contract.

Keep upstream's 60s base and escalate per consecutive rate-limit:
60s -> 2m -> 4m -> 8m -> ... capped at 4h. Counter still resets on
successful primary restore (cicae's mechanism, unchanged).

New tests: escalation doubling, 14400s cap, reset-on-restore.
Existing 60s contract test passes UNCHANGED. Mutation-checked:
escalation disabled -> 2 fail; reset disabled -> 1 fails.

Subject: [PATCH 236/311] fix(catalog): wire api_key auth headers for http MCP
 servers
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

When an optional-mcps manifest declares transport.type=http with
auth.type=api_key, install_entry() prompts for the key and saves it to
.env, but _build_server_config() only handled the oauth case — the
api_key case produced a bare url entry with no headers, so every
request to the server was unauthenticated (-> 401).

Reuse _bearer_auth_headers(entry.name) from mcp_config.py so the
catalog path emits the same 'Authorization: Bearer ${MCP_..._API_KEY}'
template as the manual 'hermes mcp add --url' path.

Salvaged from #70782 (production hunk applied clean; tests re-anchored
onto current main). Credit: JonthanaHanh.

Subject: [PATCH 237/311] perf(compressor): release allocator pages after
 successful compaction
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

A successful compaction frees the largest allocation a long session ever
drops (the compressed-away message dicts), but Python's arena allocator
keeps those pages in the heap — RSS retains the pre-compaction
high-water mark until exit. #76905's trim_memory lifecycle covers the
gateway/TUI housekeeping loops but not the CLI compression path.

Call trim_memory(reason='post-compression') at the compression-success
point in ContextCompressor.compress(), following the house pattern
(lazy import in try, debug-level log on failure). The helper is
glibc-gated, config-gated and rate-limited, so it is a safe no-op on
other platforms and cannot fail compression.

Re-expresses the intent of #70782 (JonthanaHanh), which reached for a
bare gc.collect(); trim_memory is the house mechanism and already
wraps a collect.

Subject: [PATCH 238/311] fix(catalog): validate http+api_key manifests declare
 the header's env key
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Simplify-pass follow-up on the #70782 salvage: _bearer_auth_headers
hard-emits ${MCP_<NAME>_API_KEY} but install_entry only persists
auth.env-declared vars — a manifest naming its key differently (the
shipped n8n style) would install cleanly yet send a literal-placeholder
header at connect time (silent 401, the #37792 bug class). Enforce the
naming contract at parse time. Also pins the secret-stays-in-.env
property in the install test (raw config.yaml carries the template,
never the secret). Mutation-checked: validation disabled -> guard test
fails.

+### Limiting auxiliary concurrency
+
+`max_concurrency` caps in-flight LLM calls for auxiliary tasks such as `compression` and `title_generation` across the whole process. `auxiliary.vision.max_concurrency` is excluded: it already controls only vision's CPU-bound image encode/resize workers, not LLM requests. This is most useful when:

+- Your provider is rate-limited or going through an incident and retries would amplify the burst

+  title_generation:
+    max_concurrency: 2
+  compression:

 ### OpenRouter routing & Pareto Code for auxiliary tasks
 
 When an auxiliary task resolves to OpenRouter (either explicitly or via `provider: "main"` while your main agent is on OpenRouter), the main agent's `provider_routing` and `openrouter.min_coding_score` settings **do not propagate** — by design, each auxiliary task is independent. To set OpenRouter provider preferences or use the [Pareto Code router](/integrations/providers#openrouter-pareto-code-router) for a specific aux task, set them per-task via `extra_body`:

Subject: [PATCH 240/311] fix: thread extra_headers through the call_llm split
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The PR's concurrency wrapper splits call_llm into a semaphore-guarded
entry + _call_llm_impl; main added extra_headers to call_llm's
signature after the PR's base, so the split has to forward it too
(dropped silently otherwise — Azure Foundry and custom-endpoint
callers set it).

Subject: [PATCH 241/311] fix(nix): tie devShell's HERMES_PYTHON to the venv
 actually on PATH
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

`nix/devShell.nix` collected `devShellHook` by scanning every package:

    nonNpmHooks = map (p: p.passthru.devShellHook or "") packages;

But `minimal` and `messaging` are `.override` variants of `default`, so
each carries its own `devShellHook` exporting its own HERMES_PYTHON. The
scan therefore concatenated three conflicting exports and forced Nix to
evaluate and realise three separate uv2nix editable venvs on every
`nix develop`.

`attrValues` is alphabetical, so the last hook won (`minimal`) while
`python`/VIRTUAL_ENV came from `default`'s devDeps:

    HERMES_PYTHON        = ...dimim2... (minimal — no optional deps)
    python / VIRTUAL_ENV = ...85r28... (full)

Inside the shell `$HERMES_PYTHON -c "import anthropic"` failed while
`python -c "import anthropic"` succeeded. Worse, `scripts/run_tests.sh`
prefers HERMES_PYTHON, so the suite ran against the minimal venv. Its
guard did not catch this: it only checks that HERMES_PYTHON has pytest,
and minimal's venv does (pytest is in the `dev` group), so the wrong
interpreter was silently accepted.

Tying the hook to `packages.default` — the same package whose `devDeps`
are installed — keeps HERMES_PYTHON, `python`, and VIRTUAL_ENV pointing
at one venv by construction.

    their combined closure      421 MB -> 140 MB
    test failures               85     -> 32

The venv mismatch was masking 53 failures; e.g. test_web_tools_config.py
goes 2-failed -> 38-passed. Full suite is now 25369 passed / 32 failed,
and those 32 reproduce identically on a pristine HEAD worktree with no
nix/ changes under the same interpreter (mostly NixOS artifacts — tests
spawning bare `python3` in a scrubbed env exit 127).

Subject: [PATCH 242/311] fix(system_prompt): move skills index to the volatile
 band

The skills index is runtime-mutable: the agent adds and patches skills mid-session, so it is not byte-stable. Keeping it in the stable band breaks that band prefix-cache contract, because every skill edit changes the stable band and invalidates the entire cached prefix in front of it. Move it to the front of the volatile band so the stable scaffold (identity, tool guidance, model guidance) stays cacheable across skill edits.

Simplify-pass finding: the safety note still cited 'skills edited' as a stable-tier input whose change mismatches the rebuilt prefix — after this PR a skill edit changes only the volatile tail (that's the point). Swap the example for genuinely stable-tier inputs.

Subject: [PATCH 249/311] fix: prefer explicit anthropic api key

Cherry-picked from PR #58560 by @itsflownium, adapted to current main
(_getenv instead of os.getenv). Moves ANTHROPIC_API_KEY check ahead of
Claude Code credential file and credential_pool auto-discovery so an
explicitly configured key is never shadowed by auto-discovered OAuth.

Fixes #58546

Subject: [PATCH 250/311] docs: document /personality none|default|neutral
 reset across personality docs
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The reset keywords have existed in both CLI and gateway handlers since
June but were undocumented — users couldn't find how to cancel a
personality overlay. Adds a 'Resetting to the default' section to the
personality feature page and mentions the reset in the CLI guide,
slash-command reference (both tables), and messaging command table.

Subject: [PATCH 257/311] feat(models): add qwen3.8-max to Nous portal +
 OpenRouter catalogs, replacing qwen3.7-max

Qwen3.8 Max is live on both OpenRouter and the Nous portal
(qwen/qwen3.8-max, 1M context, 131K max output). Per the
newest-max-replaces-last-max convention, it takes qwen3.7-max's slot
in both curated lists.

- hermes_cli/models.py: OPENROUTER_MODELS + _PROVIDER_MODELS[nous]
  swap qwen/qwen3.7-max -> qwen/qwen3.8-max
- agent/model_metadata.py: DEFAULT_CONTEXT_LENGTHS entry for
  qwen3.8-max at 1,000,000 (verified against OpenRouter live
  metadata and Nous /v1/models 2026-08-03)
- tests/test_empty_model_fallback.py: swap incidental catalog fixture
  to the surviving slug
- website/static/api/model-catalog.json: regenerated

Pricing snapshot skipped: both routes bill via official_models_api
(live pricing), verified with resolve_billing_route. Reasoning
timeout floor already covered by the qwen3 prefix (180s).

Subject: [PATCH 258/311] test: swap context-switch-guard fixture off
 qwen3.8-max-preview
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

test_custom_provider_context_avoids_false_shrink_warning used
qwen3.8-max-preview as a slug that deliberately falls through to the
generic 'qwen' 131K catalog match. The new qwen3.8-max
DEFAULT_CONTEXT_LENGTHS entry (1M) now substring-matches the preview
slug too, so the no-custom-providers branch stopped warning. Swap the
fixture to qwen3.9-max-preview, which still hits the generic fallback
— the test's intent (custom_providers threading) is unchanged.

Subject: [PATCH 259/311] fix(agent): keep context_length pin for named custom
 providers

Empty model.base_url plus a runtime custom-provider URL was treated as a
route mismatch, so gateway session-reset banners dropped model.context_length
and fell back to the Qwen family default (131K) while /status still showed
the configured 262K pin.

Subject: [PATCH 263/311] fix(gateway): keep event loop alive during /compress
 and Relay drain

Offload manual /compress temporary-agent cleanup through the existing
bounded off-loop helper so a slow agent.close() cannot freeze the
gateway event loop, heartbeat, or platform polling.

Guarantee Relay transport teardown even when the runner cancels
adapter.disconnect() during go_idle: shielded finally, 2s drain-path
idle ACK budget under the 5s outer disconnect budget, and bounded
supervisor/reader/ws.close awaits.

Original commits:
- fix(gateway): offload manual /compress cleanup from the event loop
- fix(gateway): tear down Relay transport even if go_idle is cancelled
- fix(gateway): keep Relay disconnect budgets inside the runner window

By @Dannyzen (PR #78027), salvaged onto current main.

Subject: [PATCH 264/311] fix(gateway): bound go_dormant ws.close with teardown
 timeout

Sibling site to the disconnect() fix: go_dormant() still did an
unbounded await self._ws.close(), the exact same pattern bounded in
disconnect(). go_dormant runs on the scale-to-zero suspend path (Fly
autostop), which also has timeout constraints. Apply the same 1s
wait_for treatment using _TEARDOWN_AWAIT_TIMEOUT_S.

Found during review of PR #78027.

Subject: [PATCH 265/311] fix: close the Codex app-server session on agent
 teardown
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Salvage of #65260's b7d7cfd0e (ported — the PR's close() predates ~4K
commits of teardown-step churn, so the hunk is re-anchored after step
6b rather than cherry-picked).

agent/codex_runtime.py already drops _codex_session on turn crash and
on retirement, but AIAgent.close() — the hard teardown for /new,
/reset, and session expiry — had no owner for it, so the app-server
child process survived until interpreter exit. Long-lived gateways
accumulate one leaked subprocess per ended Codex session.

The attribute is cleared BEFORE close() so a concurrent reader can't
observe a half-closed session and a raising close() can't strand a
stale reference (tested).

Tests extend the author's original lifecycle test with the
raising-close and no-codex-session cases.

Subject: [PATCH 266/311] fix(agent): discard bare tool-call marker before
 fallback/persistence (#78148)

Local tool-call templates can emit a bare bracketed token (e.g. "[memory]")
as assistant content alongside a function call. The loop treated that
protocol scaffolding as visible content: it got cached as the post-tool
fallback, and when the next turn came back empty, the marker was replayed
as the final response and written into the persisted transcript. Later
context compaction preserved that history, letting the model repeat the
marker in subsequent turns.

Detect content that is only a bracketed marker (`[name]`) when the
response also carries tool_calls, and drop it before it can be cached
or persisted. Scoped narrowly: only fires alongside tool_calls, so a
genuine final response of "[memory]" without a tool call is unaffected.

Subject: [PATCH 267/311] fix(agent): repair sessions already contaminated with
 stale tool-call markers (#78148)

The conversation_loop fix (previous commit) stops new "[memory]"-style
bare tool-call markers from being cached/persisted, but sessions written
before that fix can still carry rows where a bare marker was saved as
the assistant's "final response".

Add a load-on-read repair pass in hermes_state.py, mirroring the existing
_strip_background_review_harness defense-in-depth: on session restore,
any assistant row whose content is only a bracketed marker (e.g.
"[memory]", "[skill_manage]") AND that carries tool_calls has its content
blanked before the history re-enters the model's context. The tool call
and its result are left untouched so provider tool_call/tool_result
pairing stays intact. Sessions with no affected rows pass through the
normal path unchanged.

+"""Tests for stale tool-call marker session repair (hermes_state, #78148).
+
+Before the root-cause fix in ``agent.conversation_loop``, a local tool-call
+template could emit a bare bracketed marker (e.g. "[memory]") as assistant
+content alongside a real tool call. The loop cached that marker as a
+fallback and, when the following turn came back empty, replayed it as the
+"final response" — persisting it into the session as if the model had
+actually answered.
+
+``_strip_stale_tool_call_markers`` is the load-on-read defense-in-depth
+that clears any such stray marker content from sessions written before the
+fix, so resuming a polluted session doesn't re-teach the model to keep
+emitting the marker. Unaffected sessions pass through unchanged.

Subject: [PATCH 268/311] feat(cli): add sessions clean-markers to permanently
 purge stale tool-call markers (#78148)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The load-on-read repair (_strip_stale_tool_call_markers) fixes affected
sessions in memory on every resume, but never touches the DB — long-lived
sessions re-scan and re-repair the same rows on every load, and the
contaminated bytes stay in state.db (and any backup/cache snapshot of it)
indefinitely.

Add SessionDB.purge_stale_tool_call_markers(dry_run=False): a one-time,
idempotent UPDATE that permanently blanks the content column on affected
rows. Only content is touched — tool_calls and every other column are
left untouched, so provider tool_call/tool_result pairing survives.
dry_run reads through the no-lock read path and never writes.

Wire it up as `hermes sessions clean-markers [--dry-run]`, mirroring the
existing optimize/repair subcommands. Verified end-to-end against a real
temp state.db: dry-run reports the row without writing, the real run
clears it and preserves tool_calls, and a second run is a no-op.

Subject: [PATCH 269/311] fix(cli): back up state.db before clean-markers
 writes by default
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

purge_stale_tool_call_markers ran a permanent, irreversible UPDATE with
no backup — inconsistent with repair_state_db_schema's backup-by-default
convention for destructive state.db operations elsewhere in this file.

Take a full snapshot via VACUUM INTO (safe against a live connection,
unlike the raw-copy _backup_db_file used for malformed-schema repair)
before the write, timestamped beside state.db. Skipped when dry_run or
when there's nothing to change. Add --no-backup to `hermes sessions
clean-markers`, mirroring `sessions repair`.

Verified end-to-end: the CLI run against a real temp state.db produces
the backup file before printing the cleared-row count.

The bracketed-marker regex was inlined in conversation_loop.py as
re.fullmatch(r"\[...", ...) while hermes_state.py defines the same
pattern as _STALE_TOOL_CALL_MARKER_RE. Both must agree on what counts
as a stale marker — a drift here means the runtime guard silently
disagrees with the load-on-read repair and CLI purge in hermes_state.

Consolidate onto a single compiled constant (_STALE_MARKER_RE) at
module level in conversation_loop.py, with a comment noting it must
mirror _STALE_TOOL_CALL_MARKER_RE in hermes_state.py. A direct import
from hermes_state was tried first but caused a regression: hermes_state
initializes DEFAULT_DB_PATH = get_hermes_home() / 'state.db' at module
import time, which breaks tests that monkeypatch get_hermes_home() to
return a str (test_slash_worker_accepts_profile_home).

Follow-up to PR #78175 (@JoaoMarcos44).

Subject: [PATCH 271/311] fix(conversation_loop): compress messages on
 output-cap retry path (#55546)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The output-cap retry loop reduced max_tokens by 64 tokens per attempt but
never called _compress_context(), so the compressor never fired. Input
growth (~65 tokens/attempt) canceled the savings, leaving the session
stuck at 200,001 tokens — 1 over the 200,000 ceiling.

The fix adds compression to the output-cap retry path. The compressor
drops the middle window, freeing ~50% of tokens. If compression makes
>=5% savings, the session continues; otherwise vision payloads are
stripped or the session ends with compression_exhausted=True.

Also adds CHANGELOG.md entry and bug fix report.

+# Changelog
+
+## [v0.19.2] — 2026-08-03
+
+### Fixed
+- **context_compressor / conversation_loop**: Output-cap retry path now compresses message history (#55546)
+
+  Previously, when the provider returned an "output cap too large" HTTP 400, the
+  retry loop only reduced `max_tokens` by 64 tokens per attempt. The input grew by
+  ~65 tokens each retry, leaving the total stuck at 200,001 tokens — 1 token over
+  the 200,000 ceiling. After 3 retries, the session crashed with
+  `compression_exhausted=True`.
+
+  The fix adds `_compress_context()` to the output-cap retry path so the compressor
+  drops the middle window, freeing ~50% of tokens in one pass. If compression makes
+  ≥5% savings, the session continues; otherwise vision payloads are stripped, and
+  if that fails too, the session ends with a clear "cannot compress further" message.
+
+  Affected providers: vLLM, DashScope (Qwen), OpenRouter, LM Studio, Anthropic.
+
+### Testing
+- `test_output_cap_parsing.py` — output-cap error parsing across providers
+- `test_1630_context_overflow_loop.py` — context overflow heuristic and compression_exhausted flag
+- `test_preflight_compression_cap_e2e.py` — preflight compression with configurable max_attempts
+- `test_max_tokens_propagation.py` — max_tokens config propagation to gateway

+# Output-Cap Compression Fix: Detailed Report
+
+## The Bug
+
+When a provider returns an "output cap too large" HTTP 400 (e.g. `max_tokens`
+exceeds the space left in the context window), the retry path reduced
+`max_tokens` by 64 tokens per attempt but never called `_compress_context()`.
+The message compressor was not wired into this path at all.
+
+Because the compressor never fired, each retry made almost no real progress:
+input grew by ~65 tokens per attempt while the output cap shrank by 64, for a
+net effect of ~1 token per attempt. The total footprint stayed just over the
+context ceiling instead of coming back under it.
+
+## What Happened (observed token math)
+
+- Input grew per attempt: 134,465 → 134,530 → 134,595 → 134,660
+- Output cap shrank per attempt: 65,535 → 65,471 → 65,406 → 65,341 → 65,276
+- Net: ~1 token of growth per retry (65 − 64 = 1)
+- Total stayed at 200,001 tokens — 1 over the 200,000 ceiling
+- After the retry budget was exhausted, the run ended with
+  `compression_exhausted=True` and the session dropped.
+
+## How It Broke
+
+The output-cap retry loop only adjusted `max_tokens` each pass. The flag it set
+to continue — `restart_with_compressed_messages` — is named as though the
+messages get compressed, but the messages were **not** actually compressed on
+this branch. The compressor simply was not invoked, so nothing reduced the
+growing footprint.
+
+This path is old (~4 months, from a series of compaction/output-cap changes),
+but the details of exactly which change first introduced it are less important
+than the current behavior and the fix.
+
+## Root Cause (factual)
+
+The output-cap handling dates back to a compaction/output-cap change Apr 2026;
+it was later refactored into `agent/conversation_loop.py` (May 2026) and its
+cap calculation refined (Jul 2026). The defect is behavioral rather than
+attributable to one edit: the output-cap branch set
+`restart_with_compressed_messages = True` without ever calling
+`_compress_context()`, so nothing actually shrank the in-flight footprint.
+
+## Why It Surfaced Now (Aug 2026)
+
+The bug is old (~4 months) but latent — it only becomes reachable when a
+conversation actually fills or near-fills its context window **and** the
+provider returns the specific "output cap too large" wording the parser
+matches. That combination is rare; most sessions never get near the ceiling.
+
+What changed leading up to the first real-world exposure in early Aug 2026:
+
+1. Two token-estimator accuracy fixes reduced the reported token counts:
+   - `530503a6a` (2026-07-28): exclude `reasoning_details` from the preflight
+     estimate. Its own message notes that field inflated the rough estimate by
+     ~4x and caused compression far too early (a measured session reported
+     ~533K estimated vs ~140K real).
+   - `e3bc51703` (2026-07-31): stop double-counting `api_content`.
+2. The preflight auto-compression gate (`should_compress()` ->
+   `should_compress_info()`) uses the same estimator, comparing
+   `prompt_tokens >= threshold_tokens`, where
+   `threshold_tokens ≈ (context_length − max_tokens) × 0.50`. With these fixes,
+   the estimate dropped, so preflight judged sessions "under threshold" and
+   deferred compression far longer than before.
+3. A long-running session therefore reached the hard context ceiling for the
+   first time, hit the provider's output-cap 400, and entered the output-cap
+   retry branch — which (pre-fix) never compressed and death-looped.
+
+In short: the Jul estimator fixes did not introduce the death-loop; they
+unmasked it. They removed the (over-aggressive) early compression that had been
+silently keeping sessions away from the ceiling, exposing the latent
+never-compresses-on-output-cap defect.
+
+## The Fix
+
+Add `_compress_context()` to the output-cap retry path so the message history
+is actually compressed before retrying:
+
+1. The compressor drops the middle window, freeing a large fraction of tokens
+   in a single pass.
+2. If compression made real progress, the session continues under the ceiling.
+3. If compression could not reduce further, vision payloads are stripped and it
+   retries again.
+4. Compression failures are non-fatal: if anything goes wrong during
+   compression, the code falls back to retrying on `max_tokens` alone. The
+   existing max-attempts guard still bounds the retry loop, so it cannot spin
+   forever.
+
+## Verification
+
+- Both output-cap retry regression tests pass:
+  `test_output_cap_retry_uses_provider_available_out` and
+  `test_output_cap_retry_with_large_api_only_content`.
+- Full `tests/run_agent/test_run_agent.py`: 232 passed, 1 failed — and the 1
+  failure (`test_interruptible_anthropic_interrupt_never_closes_shared_client`)
+  is a pre-existing environment issue (missing `anthropic` package), failing
+  identically on a clean base without this change.
+- `ruff check` passes on both modified files.
+
+## Impact
+
+- Sessions at the context ceiling now recover via message compression instead
+  of exhausting retries.
+- Applies across providers (vLLM, DashScope/Qwen, OpenRouter, LM Studio,
+  Anthropic). Additive fix; no breaking changes.
+
+## Affected Code
+
+`agent/conversation_loop.py` — the output-cap retry block (added compression to
+the retry path that previously only adjusted `max_tokens`).

-## [v0.19.2] — 2026-08-03
-
-### Fixed
-- **context_compressor / conversation_loop**: Output-cap retry path now compresses message history (#55546)
-
-  Previously, when the provider returned an "output cap too large" HTTP 400, the
-  retry loop only reduced `max_tokens` by 64 tokens per attempt. The input grew by
-  ~65 tokens each retry, leaving the total stuck at 200,001 tokens — 1 token over
-  the 200,000 ceiling. After 3 retries, the session crashed with
-  `compression_exhausted=True`.
-
-  The fix adds `_compress_context()` to the output-cap retry path so the compressor
-  drops the middle window, freeing a large fraction of tokens in one pass. If
-  compression makes ≥5% token savings (or drops the message count), the session
-  continues under the ceiling. If compression cannot reduce the request, the loop
-  retries with the reduced `max_tokens` and, if the error keeps recurring,
-  terminates through the existing max-attempts guard with a clear "cannot compress
-  further" message — it no longer spins on `max_tokens` alone. Compression failures
-  stay non-fatal and fall back to retrying on `max_tokens` alone.
-
-  Affected providers: vLLM, DashScope (Qwen), OpenRouter, LM Studio, Anthropic.
-
-### Testing
-- `test_output_cap_parsing.py` — output-cap error parsing across providers
-- `test_1630_context_overflow_loop.py` — context overflow heuristic and compression_exhausted flag

-# Output-Cap Compression Fix: Detailed Report
-
-## The Bug
-
-When a provider returns an "output cap too large" HTTP 400 (e.g. `max_tokens`
-exceeds the space left in the context window), the retry path reduced
-`max_tokens` by 64 tokens per attempt but never called `_compress_context()`.
-The message compressor was not wired into this path at all.
-
-Because the compressor never fired, each retry made almost no real progress:
-input grew by ~65 tokens per attempt while the output cap shrank by 64, for a
-net effect of ~1 token per attempt. The total footprint stayed just over the
-context ceiling instead of coming back under it.
-
-## What Happened (observed token math)
-
-- Input grew per attempt: 134,465 → 134,530 → 134,595 → 134,660
-- Output cap shrank per attempt: 65,535 → 65,471 → 65,406 → 65,341 → 65,276
-- Net: ~1 token of growth per retry (65 − 64 = 1)
-- Total stayed at 200,001 tokens — 1 over the 200,000 ceiling
-- After the retry budget was exhausted, the run ended with
-  `compression_exhausted=True` and the session dropped.
-
-## How It Broke
-
-The output-cap retry loop only adjusted `max_tokens` each pass. The flag it set
-to continue — `restart_with_compressed_messages` — is named as though the
-messages get compressed, but the messages were **not** actually compressed on
-this branch. The compressor simply was not invoked, so nothing reduced the
-growing footprint.
-
-This path is old (~4 months, from a series of compaction/output-cap changes),
-but the details of exactly which change first introduced it are less important
-than the current behavior and the fix.
-
-## Root Cause (factual)
-
-The output-cap handling dates back to a compaction/output-cap change Apr 2026;
-it was later refactored into `agent/conversation_loop.py` (May 2026) and its
-cap calculation refined (Jul 2026). The defect is behavioral rather than
-attributable to one edit: the output-cap branch set
-`restart_with_compressed_messages = True` without ever calling
-`_compress_context()`, so nothing actually shrank the in-flight footprint.
-
-## Why It Surfaced Now (Aug 2026)
-
-The bug is old (~4 months) but latent — it only becomes reachable when a
-conversation actually fills or near-fills its context window **and** the
-provider returns the specific "output cap too large" wording the parser
-matches. That combination is rare; most sessions never get near the ceiling.
-
-What changed leading up to the first real-world exposure in early Aug 2026:
-
-1. Two token-estimator accuracy fixes reduced the reported token counts:
-   - `530503a6a` (2026-07-28): exclude `reasoning_details` from the preflight
-     estimate. Its own message notes that field inflated the rough estimate by
-     ~4x and caused compression far too early (a measured session reported
-     ~533K estimated vs ~140K real).
-   - `e3bc51703` (2026-07-31): stop double-counting `api_content`.
-2. The preflight auto-compression gate (`should_compress()` ->
-   `should_compress_info()`) uses the same estimator, comparing
-   `prompt_tokens >= threshold_tokens`, where
-   `threshold_tokens ≈ (context_length − max_tokens) × 0.50`. With these fixes,
-   the estimate dropped, so preflight judged sessions "under threshold" and
-   deferred compression far longer than before.
-3. A long-running session therefore reached the hard context ceiling for the
-   first time, hit the provider's output-cap 400, and entered the output-cap
-   retry branch — which (pre-fix) never compressed and death-looped.
-
-In short: the Jul estimator fixes did not introduce the death-loop; they
-unmasked it. They removed the (over-aggressive) early compression that had been
-silently keeping sessions away from the ceiling, exposing the latent
-never-compresses-on-output-cap defect.
-
-## The Fix
-
-Add `_compress_context()` to the output-cap retry path so the message history
-is actually compressed before retrying:
-
-1. The compressor drops the middle window, freeing a large fraction of tokens
-   in a single pass.
-2. If compression made real progress (message count dropped, or ≥5% token
-   savings), the session continues under the ceiling.
-3. If compression could not reduce the request, the loop retries with the already
-   reduced `max_tokens` and, if the error keeps recurring, terminates through the
-   existing max-attempts guard with a clear "cannot compress further" message.
-4. Compression failures are non-fatal: if anything goes wrong during
-   compression, the code falls back to retrying on `max_tokens` alone. The
-   existing max-attempts guard still bounds the retry loop, so it cannot spin
-   forever.
-
-## Verification
-
-- Both output-cap retry regression tests pass:
-  `test_output_cap_retry_uses_provider_available_out`, and
-  `test_output_cap_retry_with_large_api_only_content`.
-- New `test_output_cap_retry_triggers_compression_and_recovers` locks in the
-  fix and asserts that the retry sends the compressed history on the wire (not
-  the original oversized request) and that `context_length` is untouched.
-- New `test_output_cap_retry_compression_no_progress_terminates_bounded` locks
-  in that a zero-progress compression terminates via the max-attempts guard
-  rather than spinning forever.
-- Full `tests/run_agent/test_run_agent.py`: 235 passed with the optional
-  `anthropic` package installed. (Without it, the single
-  `test_interruptible_anthropic_interrupt_never_closes_shared_client` fails on
-  an ``ImportError: The 'anthropic' package is required`` — an environment
-  issue, unrelated to this change.)
-- `ruff check` passes on both modified files.
-
-## Impact
-
-- Sessions at the context ceiling now recover via message compression instead
-  of exhausting retries.
-- Applies across providers (vLLM, DashScope/Qwen, OpenRouter, LM Studio,
-  Anthropic). Additive fix; no breaking changes.
-
-## Affected Code
-
-`agent/conversation_loop.py` — the output-cap retry block (added compression to
-the retry path that previously only adjusted `max_tokens`).

 recomputing estimate_request_tokens_rough

The output-cap error handler already computes request_input_estimate at
line 4722 via estimate_request_tokens_rough(api_messages, tools=...).
The new compression block ~50 lines below was calling the same function
with the same inputs again. Reuse the existing local.

Subject: [PATCH 277/311] perf(gateway): prewarm /model picker cache on TUI
 startup

The classic CLI run() loop calls prewarm_picker_cache_async() during the
idle window after the banner is shown, so the first /model open hits a warm
provider-models disk cache and renders in ~100ms. The stdio TUI entry point
never did this, so the first /model open in a TUI session blocked on serial
/v1/models fetches for every authenticated provider.

Mirror the CLI behaviour: kick off the same off-thread prewarm right after
gateway.ready is emitted (banner shown, user about to type). Fire-and-forget,
guarded once-per-process, fully exception-isolated so a slow or offline
provider can never affect TUI startup.

Subject: [PATCH 278/311] test(tui): pin picker-cache prewarm wiring in
 entry.main()
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

teknium's review gap on #72021: the helper's worker/once-guard was
covered, but nothing asserted the stdio TUI entry point actually
invokes prewarm_picker_cache_async() — or that it does so in the right
place. Add a focused entrypoint test that runs the real entry.main()
with stubbed collaborators (same monkeypatch-module-attrs harness as
test_tui_entry_mcp_owner.py), spies on the helper in
hermes_cli.model_switch (the lazy-import source), and asserts:

- prewarm fires exactly once, strictly AFTER the gateway.ready write
- startup stays non-blocking: main() reaches the stdin loop and
  returns on EOF
- a prewarm failure is swallowed (fire-and-forget) without breaking
  startup

Mutation-checked: deleting the prewarm hunk from entry.py fails both
tests.

Subject: [PATCH 279/311] perf(cli): check local auth.json/config before slow
 provider registry sweep

_has_any_provider_configured() probed every api_key provider (gh subprocess
for copilot alone takes 5s; full sweep ~18s) before consulting auth.json and
config.yaml, which are instant local reads. Desktop setup.status calls
blocked past the UI's timeout, causing the connect/disconnect boot loop.
Reorder so cheap local checks run first. Same semantics, ~35x faster here.

Subject: [PATCH 280/311] test(cli): regression tests pinning auth-first
 ordering skips registry sweep

Teknium's review on #63457: existing tests pin the final boolean but not
that the slow PROVIDER_REGISTRY sweep is skipped. Add three tests that
booby-trap hermes_cli.auth.get_auth_status and verify
_has_any_provider_configured() short-circuits on:
- config.yaml model.provider
- config.yaml base_url/api_key (custom endpoint shape)
- auth.json active_provider (sweep-only call-pattern guard)

Mutation-checked: reverting the reorder makes all three fail.

Subject: [PATCH 284/311] perf(gateway): replace SSE poll loop with
 call_soon_threadsafe-fed asyncio.Queue
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

_write_sse_chat_completion and _write_sse_responses bridged their
stream_delta_callback queue into the event loop via
`await loop.run_in_executor(None, lambda: stream_q.get(timeout=0.5))`
in a while-True poll — a thread-pool round trip on every 0.5s tick even
when idle, plus up to 500ms of tail latency between a delta landing in
the queue and it reaching the SSE response.

Add ThreadSafeAsyncQueue (asyncio.Queue + a put_threadsafe() that wraps
call_soon_threadsafe), used by both streaming producer closures
(_on_delta, tool start/complete callbacks — all invoked from the worker
thread running run_conversation via loop.run_in_executor). Consumers
now do a plain `await asyncio.wait_for(stream_q.get(), timeout=0.5)` —
woken immediately when a delta arrives, no executor hop, no poll
interval.

Updated tests/gateway/test_sse_agent_cancel.py's 7 call sites to
construct ThreadSafeAsyncQueue inside the running loop (required, since
it captures asyncio.get_running_loop() at construction) instead of a
bare queue.Queue() at test-method scope.

Subject: [PATCH 285/311] refactor(gateway): extract _sse_frame() helper, dedup
 5 inline SSE encode call sites
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

_write_sse_chat_completion had five near-identical
f"data: {json.dumps(...)}\n\n".encode() (and one event-tagged variant)
scattered across its role/content/finish/error chunk writes. Pure
extract-method, no behavior change: encoding is byte-identical for every
call site touched.

Left the pre-serialized-string writers elsewhere (_write_event's
json.dumps(..., ensure_ascii=False) path, the /v1/runs SSE writer) alone
— routing them through this helper's plain json.dumps(data) would
silently change their unicode-escaping behavior, which is out of scope
for a pure dedup.

Subject: [PATCH 286/311] refactor(gateway): route all three SSE writers
 through _sse_frame()
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

_extend _sse_frame with an explicit ensure_ascii param (default True,
byte-identical to a bare json.dumps) and route the two sibling writers
through it: _write_sse_responses._write_event and the /v1/runs event
stream. This completes the dedup PR #65009 — previously only the five
_write_sse_chat_completion sites used the helper, leaving the other two
writers on inline json.dumps with no shared shape.

No behavior change: every writer's emitted bytes are unchanged (verified
byte-for-byte, including non-ASCII payloads where the default
ensure_ascii=True matches the original inline encoders). The ensure_ascii
option is exposed so a future writer can opt into raw non-ASCII bytes
without fractalizing the format again.

Adds tests/gateway/test_sse_frame.py asserting the byte-contract
invariant between _sse_frame and the historical inline encoders.

Subject: [PATCH 287/311] refactor(gateway): route session event stream through
 _sse_frame (ensure_ascii=False)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The session event stream (api_server.py:~2236) was the one genuinely
unicode-distinct SSE writer — json.dumps(payload, ensure_ascii=False) +
.encode('utf-8'). Every other writer uses plain json.dumps. Route it
through _sse_frame(..., ensure_ascii=False) so _sse_frame is now the single
source of truth for ALL SSE frame serialization in the module (chat-
completion, responses._write_event, /v1/runs, and the session stream).

Byte-identical for non-ASCII payloads: verified against the historical
inline encoder (raw bytes preserved). The ensure_ascii=False path is now
exercised by test_sse_frame_ensure_ascii_false_reproduces_session_event_stream.

Subject: [PATCH 290/311] perf(tui): bound reasoning-clean input to the
 displayed tail
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

CI caught a split defect in this salvage: the PR's long-reasoning tail
test was kept but its production hunk was dropped as 'cosmetics'. It
isn't — cleanThinkingText runs several full-string regex passes and
reasoning grows on every streamed token, so re-cleaning the whole
accumulated string per chunk is O(n) per token / O(n^2) per stream.
Only the tail is displayed (boundedLiveRenderText caps it downstream),
so bound the input to 1.5x LIVE_RENDER_MAX_CHARS first.

Restores the one text.ts hunk from cd99e65fc (author preserved); the
italic-thinking display change and profile script from that commit
remain out of scope.

Subject: [PATCH 291/311] test: exercise the production _loop_ref path in
 put_threadsafe tests
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Gate finding (/simplify-code pass): both cross-thread tests passed
loop=loop explicitly, but no production caller does — all six
(_on_delta, _on_tool_*) rely on the queue resolving its own
_loop_ref in __init__. The kwarg made the tests vacuous: a broken
_loop_ref still passed them.

Dropping the kwarg exercises the real path. Verified by mutation:
with self._loop_ref = asyncio.new_event_loop() (wrong loop), both
tests now FAIL; they passed before this change.

Subject: [PATCH 292/311] fix(test): feed the SSE writers an asyncio queue, not
 queue.Queue

CI caught a missed caller-shape update. Both PRODUCTION callers of
_write_sse_chat_completion / _write_sse_responses were converted to
ThreadSafeAsyncQueue, but two pre-existing tests in
tests/gateway/test_api_server.py construct the writer's queue
themselves and still passed a stdlib queue.Queue.

The consumer now does 'await asyncio.wait_for(stream_q.get(), ...)',
which on a queue.Queue blocks the thread forever:
test_stream_cancelled_persists_incomplete_snapshot hung until
pytest-timeout killed it (CI reported the whole file as 'no tests
ran (timeout before collection)'). The sibling disconnect test only
survived because it pre-fills before the first await.

tests/gateway/test_api_server.py: 99 passed (was 1 failed + a 60s
hang); with the SSE/api_server suites: 147 passed.

Subject: [PATCH 293/311] fix(credential-pool): re-select in acquire_lease
 after a deferred refresh
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

select() re-selects once deferred single-use-token refreshes complete;
acquire_lease() performed the refresh but returned its pre-refresh
answer. Since _acquire_lease_under_lock returns early exactly when a
refresh is pending (if not available: return None, pending_refresh),
a pool whose entries all needed a refresh always returned None — the
caller failed an answerable request right after the refresh succeeded.

Retry once, only when the first pass was empty and a refresh ran.

Post-merge gate-sweep finding on the #71775 salvage (#77714).

Subject: [PATCH 294/311] fix(credential-pool): lock the quarantine
 read-modify-write of _entries
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

#71775 moved deferred single-use-token refreshes outside the pool lock
(correct — they hold a cross-process flock plus network I/O). But
_refresh_entry_impl's three terminal-auth-failure quarantine paths do a
bare read-modify-write of self._entries. Those used to run with the
caller holding self._lock; on the deferred path they run unlocked, so a
concurrent mutation between the read and the write is silently lost.

Wrap all three in 'with self._lock' (an RLock, so locked callers
re-enter safely) and correct the _refresh_pending_entries docstring,
which claimed the mutations were already self-locking.

Post-merge gate-sweep finding on the #71775 salvage (#77714).
Sibling to the acquire_lease re-select fix.

Subject: [PATCH 295/311] perf(file-ops): eliminate redundant subprocess calls
 in write_file and V4A patch path
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

write_file currently spawns up to 6 subprocesses per call:
  1. mkdir -p (separate call before atomic write)
  2. cat (to read pre-content for lint/BOM/line-ending detection)
  3. _atomic_write (mktemp + write + mv — the essential one)
  4. wc -c (to measure bytes written)
  5. _check_lint_delta (post-write lint — also essential)
  6. LSP snapshot (also essential)

This PR removes three of them without changing any observable behavior:

1. Fold mkdir -p into _atomic_write shell script (−1 subprocess/write)
   The atomic write script already runs a single shell; adding mkdir -p
   to it costs zero extra processes.

2. Add optional pre_content parameter to write_file (−1 subprocess/patch)
   patch_replace and V4A _apply_update already read the file for fuzzy
   matching. Passing that content as pre_content skips the redundant cat
   inside write_file. Fully backward-compatible: callers that don't pass
   pre_content still read from disk as before.

3. Replace wc -c with len(content.encode('utf-8')) (−1 subprocess/write)
   We already have the content in memory; encoding it to get the byte count
   is equivalent to wc -c for UTF-8 text.

4. Remove redundant _check_lint loop in apply_v4a_operations (−N subprocesses/V4A)
   write_file already runs _check_lint_delta internally. The old code ran a
   bare _check_lint(f) loop over all modified files — a re-read + re-lint
   without post_content context. Now lint results propagate from write_file
   via a four-tuple return, zeroing out the extra subprocesses.

Net effect:
  - write_file: 6 → 3 subprocesses per call (new files)
  - patch_replace: 6 → 5 subprocesses per call (pre_content skips cat)
  - V4A multi-file patches: saves 1 subprocess per modified file
  - A typical 4-file V4A patch drops from ~28 to ~16 subprocess calls

Subject: [PATCH 296/311] fix(file-ops): decouple BOM detection from
 pre_content, add V4A backward compat
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Bug 1 (UTF-8 BOM loss on V4A UPDATE):
_file_has_bom() trusted pre_content for BOM detection, but the most
common pre_content provider — read_file_raw() — deliberately strips
BOMs so the agent never sees U+FEFF glyphs.  Passing BOM-stripped
content through pre_content caused a false-negative: the method
returned False and write_file() silently removed the marker on rewrite.

Fix: _file_has_bom() now always probes the first 3 bytes on disk
(head -c 3), ignoring pre_content for BOM purposes.  pre_content is
still used by two other consumers — line-ending detection and lint/LSP
delta computation — neither of which is affected by BOM stripping.

Bug 2 (backward compatibility):
_apply_update() called write_file(path, content, pre_content=...) as a
keyword argument.  Duck-typed file_ops implementations that only
implement the two-argument write_file(path, content) contract would
raise TypeError.

Fix: wrap the call in try/except TypeError, falling back to the
two-argument form when the keyword is not accepted.

Also declare tomli in pyproject.toml (pre-existing conditional import
for pre-3.11 Python, caught by the pre-commit dep scan after staging
file_operations.py).

Tests:
Add TestV4ABomRoundTrip with two cases:
  - UPDATE on BOM-bearing file preserves the marker
  - UPDATE on plain file does not inject a BOM

Addresses teknium1 review on PR #55661.

Content that flowed through a surrogateescape decode (backend output via

UnicodeEncodeError where the old wc -c path could not. Mirrors the

- write_file: encode content once, share bytes between bytes_written and
  the sha256 verification (drops a second full-content encode per write)
- patch_parser: replace the except-TypeError retry around
  write_file(pre_content=...) with signature-based feature detection so a
  TypeError raised inside a capable implementation propagates instead of
  triggering a duplicate write; tests for both duck-typing contracts
- tests: real-ops V4A BOM round-trip + _file_has_bom disk-probe guard
  (the teknium1-review regression previously only covered by a fake)
- comment: document dirs_created's long-standing "parent ensured" meaning

tomli fallback branch in _lint_toml_inproc was unreachable. Removes
the dependency from pyproject.toml + uv.lock and deletes the dead

Subject: [PATCH 301/311] fix(telegram+sqlite): resolve polling conflict loop +
 misleading WAL warning
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

#75017: Telegram polling conflict retry used drop_pending_updates=False,
starting a new getUpdates session that immediately got 409'd by the
previous still-expiring session — creating the very conflict it was
trying to recover from. Switch to drop_pending_updates=True so Telegram
terminates stale sessions. Also add a recovery-generation guard so the
first transient getUpdates success after a retry doesn't reset the
conflict counter back to 0 (defense-in-depth from PR #75096).

#75153: The WAL-reset warning always said 'hermes update can repair'
even for git/pip/system Python installs where it can't. Now uses
detect_install_method() + recommended_update_command_for_method() to
give a context-appropriate hint (hermes update for git, docker pull for
docker, nix message for nix, generic install hint as fallback).

Subject: [PATCH 303/311] fix(dashboard): reload loopback tabs after stale
 session-token closes

Loopback dashboard tabs now share one one-shot stale-token recovery path across REST 401s, the PTY socket, the structured event socket, and the shared JSON-RPC gateway wrapper. The shared client exposes only an optional close-event interception hook; the dashboard remains responsible for deciding that loopback 4401 means reload.

Constraint: Current main delegates the web gateway to apps/shared JsonRpcGatewayClient, and #54022 review requires a shared-client-compatible close-code hook plus direct ChatSidebar event-socket coverage.
Rejected: Restore the dashboard's old direct WebSocket implementation | stale against the shared JSON-RPC client and would duplicate transport behavior.
Confidence: high
Scope-risk: moderate
Directive: Keep stale-token policy dashboard-specific; the shared JSON-RPC client should expose close events without learning dashboard auth semantics.
Tested: npm --workspace web test (21 files, 106 tests); focused stale-token tests (5 files, 14 tests); npm --workspace web run typecheck; npm --workspace @hermes/shared run lint; npm --workspace @hermes/shared run typecheck; focused web eslint; git diff --check.
Not-tested: Manual browser smoke test across a real dashboard restart.

Subject: [PATCH 304/311] fix: update ChatPage test import for react-router v7

react-router v7 exports MemoryRouter from 'react-router', not
'react-router-dom'. The test was written when the repo still imported
from 'react-router-dom' (4000+ commits ago).

Subject: [PATCH 305/311] fix: wire HermesConsoleModal WS into stale-token
 reload guard
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Sibling site missed by PR #54022 — /api/console WebSocket in
HermesConsoleModal.tsx has the same buildWsUrl → stale-token → 4401
close path as the PTY and events WebSockets. Without this guard,
opening the console after a dashboard restart shows 'Console closed
(4401). auth: token_mismatch' with no recovery.

Subject: [PATCH 306/311] fix(xai): honor configured web search backend on
 Responses path

When Grok runs on xAI Responses, only swap to native server-side
web_search when the active/configured backend is xai. For Firecrawl
and other Hermes providers, keep client dispatch under a renamed wire
tool so Grok cannot hijack web_search and ignore user config.

Subject: [PATCH 307/311] test(xai): cover Firecrawl vs native web_search on
 Responses

Lock in backend preference, wire-name aliasing, and normalize mapping
so configured non-xai search providers stay on the Hermes client path.
Also init conflict-recovery generation on the telegram bare-adapter
helper so CI polling progress tests do not AttributeError.

Subject: [PATCH 308/311] refactor(xai): simplify
 _xai_prefers_native_web_search to use registry

Drop the manual web.search_backend / web.backend config-reading block
that duplicated _read_config_key in web_search_registry.py. The function
now delegates directly to get_active_search_provider() (which reads the
same config keys via the registry's canonical resolver) and falls back
to _get_search_backend() only when the registry has no providers loaded.

Also updates the TestXaiWebSearchBackendPreference tests to monkeypatch
the registry instead of load_config_readonly, and adds two new tests for
the legacy fallback path (no provider registered -> _get_search_backend).

Subject: [PATCH 310/311] fix(model-switch): treat models dict as metadata, not
 allowlist
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

hermes model saves custom_providers models: {default: {context_length}} for
local Ollama. That dict shape was treated as an explicit catalog, so no-key
endpoints skipped live /v1/models probing and Desktop/Telegram only showed
the saved default — Refresh could not help. Keep list/string shapes as
allowlists; pin dict catalogs with discover_models: false.
