kshitij 321cbcc2e2 test(redact): add YAML ReDoS test, strengthen existing test with keyword
- Relax timing bound from 1.0s to 2.0s (CI machine robustness).
- Add test_long_dotted_run_with_keyword_completes_fast: includes a secret
  keyword so the pre-gate does NOT skip _CFG_DOTTED_RE — directly exercises
  the possessive-quantifier regex, not just the pre-gate.
- Add test_yaml_assign_redos_resistance: _YAML_ASSIGN_RE was modified but
  had no ReDoS test — add 100-line stress input.
- Add test_yaml_assign_secret_still_redacted: verify YAML matching behavior
  preserved with possessive quantifiers.

carlotestor 13ad903a3c perf(redact): eliminate exponential backtracking in config-key patterns
_CFG_DOTTED_RE's nested quantifier (?:[A-Za-z0-9_\-]+\.)+ backtracks
exponentially on long non-matching dotted runs (doubles every ~4
segments). Flatten it and use possessive quantifiers (py3.11+) in
_CFG_DOTTED_RE and _YAML_ASSIGN_RE wherever the successor is disjoint.

Zero behavior change: equivalence fuzz-verified over 120k structured
and random inputs comparing full sub() output including groups. Adds a
ReDoS regression test.

kshitij 536754919d fix(auxiliary): replan cache sections on the async fallback path too
_call_fallback_candidate_sync replans messages/tools for each resolved
destination, but its async mirror still shipped the caller's decorated
sections verbatim — the primary destination's markers (including a
direct-native tool marker) leaked to fallback candidates with different
cache contracts, and the relay saw the display label instead of the
resolved provider/api_mode. Mirror the sync path: resolve the
destination, replan both sections, thread provider/api_mode through
_relay_async_completion, and replan again for the auth-refresh retry
client. Mutation-checked: the new parity test fails on the verbatim
pass-through shape.

Follow-up to #76032 (#20880).

kshitij 7ae4a5efba fix(prompt-caching): consolidate static-prefix split, guard empty volatile suffix
_apply_static_prefix_marker duplicated _apply_system_cache_markers' split
logic minus its empty-suffix guard: when the stored system prompt equals
the static prefix exactly, the tool-cache plan emitted a two-part split
with a trailing empty text block — HTTP 400 on native Anthropic. Fold the
tool-cache layout into the existing helper via mark_suffix /
fallback_to_whole flags; the empty-suffix case now marks the prompt as
one whole block. Behavior-parity verified against the merged planner for
every non-empty-suffix shape.

kshitijk4poor e078c8c6ef fix: widen fallback warning to the sibling custom-endpoint 256K path
Review pass 2 (reuse reviewer HIGH): the step-3b probe-down fallback for
custom/local endpoints returns the same silent 256K default but only
logged at INFO - invisible by default, and it is the MORE common path
for small local models (the exact users the warning exists for).

Extract _warn_context_length_fallback() (deduped per model+base_url)
and call it from both fallback sites, per the fix-the-whole-bug-class
rule. Regression test drives the custom-endpoint path and fails without
the widening (mutation-checked).

kshitijk4poor 4c2d0c7fd8 refactor: dedupe fallback warning per model, drive pool-cleanup tests through real run()
Review follow-up:
- Warn once per (model, base_url) at the step-9 fallback via a module-level
  dedup set (established _WARNED_* idiom). The fallback result is
  deliberately never cached, so the un-deduped warning fired on every
  resolution - e.g. once per gateway message via the session-hygiene path.
- Replace the three inline-mock pool-cleanup tests (which reproduced the
  try/except block against a MagicMock and passed even with the production
  code reverted) with a parametrized test that drives the real
  BatchRunner.run() with a patched Pool; drop the CPython stdlib
  signature change-detector test.
- Add a once-per-model warning regression test; clean up dead imports.

All tests verified to fail against pre-PR batch_runner.py/model_metadata.py
and pass with the fix (mutation check).

kshitijk4poor a1ff62a139 fix: context-length fallback logging, batch trajectory durability, pool cleanup
Salvage of #6629 by aaronlab (kshitijk4poor reworked against current main).

Three concerns from the original PR, reworked to address review feedback:

1. Context-length fallback diagnostic (agent/model_metadata.py):
   get_model_context_length() silently returned 256K when all 9 detection
   methods failed. Users with small-context models (8K, 32K) would get 256K
   silently, causing hard-to-debug API context-length errors. Added a
   warning log at the step 9 fallback with model name, base_url, and the
   correct config override hint (model.context_length, not context_length).
   The token-estimation ceiling-division fix from the original PR already
   landed on main (5c2ecdec) with CJK handling — not duplicated here.

2. Fsync for batch trajectory writes (batch_runner.py):
   Trajectory entries were written without flush/fsync, but the checkpoint
   immediately marked them as completed. A crash between write and disk
   sync would leave the checkpoint claiming completion with no trajectory
   data on disk. Added flush() + os.fsync() before checkpoint update.

3. Pool cleanup on interruption (batch_runner.py):
   Ctrl+C during pool.imap_unordered() relied on context manager cleanup
   which can hang. Added explicit pool.terminate() + pool.join() for both
   KeyboardInterrupt and Exception paths. The original PR used
   pool.join(timeout=10) which is invalid — CPython's Pool.join() takes
   no timeout parameter. Fixed to use pool.join() without arguments.

Tests:
  - test_warning_emitted_on_fallback: verifies warning fires at step 9
  - test_no_warning_when_cached: verifies no false warning when cache hits
  - test_trajectory_entry_is_synced_to_disk: verifies os.fsync is called
  - test_pool_terminate_called_on_exception: verifies cleanup on RuntimeError
  - test_pool_terminate_called_on_keyboard_interrupt: verifies cleanup on Ctrl+C
  - test_pool_join_called_without_timeout: verifies no timeout arg to join()
  - test_real_pool_join_accepts_no_timeout: integration check on CPython API

ajzrva-sys 34c11fa689 fix(terminal): honor explicit config keys over stale env
Let terminal keys explicitly present in config.yaml override matching stale TERMINAL_* values while preserving environment values for omitted keys. Merged defaults remain backfill-only.

hans f09c56c003 fix(gateway): dedup model-switch markers so they don't accumulate in history
Each mid-session `/model` switch appended a `[System: The active model for
this chat has changed to …]` user-role marker to the live conversation history
and never removed the prior one. N switches left N stale markers, all re-sent
to the provider on every subsequent turn — the issue measured ~80-120 tokens
each (Chinese+English), so 5 MoA-preset switches burned ~400-600 context
tokens per API call, permanently. Only the newest marker is meaningful (it
names the currently-active model); the rest are pure waste. Fixes #65891.

`_append_model_switch_marker` now strips any earlier markers from
`session["history"]` (in place, under the existing history_lock) before
appending the new one, so the live payload carries exactly one marker. This is
the payload re-sent each turn, and it's self-healing across resumes: whatever
markers a history reload brings back, the next switch collapses to one.

A stable `_MODEL_SWITCH_MARKER_PREFIX` constant is shared by the builder and
the `_is_model_switch_marker` predicate so the two can't drift; the marker
string itself is byte-for-byte unchanged. Existing behavior (role='user' per
the single db.append_message persistence) is preserved.

Scope note: this dedups the in-memory history (the per-turn cost the issue
quantifies). The DB still persists one row per switch for audit/resume; I did
NOT soft-archive prior marker rows because `active=0, compacted=0` is the
repo's rewind/undo sentinel (hermes_state.py get_messages docs), so
deactivating a marker naively would make it look rewound — a follow-up that
needs its own archive semantics.

Tests (tests/tui_gateway/test_model_switch_marker_role.py, +5): second switch
replaces (not stacks) the marker; the issue's exact 5-MoA-switch sequence
leaves one marker naming the last model; real conversation turns are preserved
in order; a stale marker sitting between turns is stripped; history_version
increments once per switch. `pytest test_model_switch_marker_role.py` → 13
passed (8 existing unchanged). Authored on Windows.

BB-light e9d52d2bda fix(caching): honor prompt_caching.cache_ttl disable in config
Setting prompt_caching.cache_ttl to a falsy value (false, null, off,
disabled, no, none) now fully disables prompt caching instead of
being silently ignored.

The disable propagates through anthropic_prompt_cache_policy() (early
return when _cache_disabled flag is set) and restore_primary_runtime()
(override after snapshot restore), so it survives /model switches and
fallback re-derivation — the gap that caused #56105 to be reverted in
#56126.

Salvage of #33555 by @BB-light, with model-switch/fallback survival
gap fixed on top.

kshitijk4poor 23c13589dd fix(acp): serialize late MCP refresh with turn start + self-sufficient agent-build wait
Review follow-ups on the #32811 salvage:
- Hold state.runtime_lock and bail on is_running so the pre-first-turn
  guard can't race the first prompt dispatch (a refresh publishing
  mid-turn would swap tools= and break the just-created cache prefix).
  Regression test mutation-checked (guard removed -> test fails).
- In-memory-only session lookup in the daemon: get_session() falls
  through to a DB restore that builds a whole new AIAgent just to
  decide no-op (TUI equivalent also checks its in-memory dict only).
- Pass quiet_mode=True explicitly, matching the TUI/gateway callers.
- Use ensure_mcp_discovery_before_agent_build() (landed on main after
  the PR) instead of bare wait_for_mcp_discovery() so the ACP agent
  build is self-sufficient and gets the retry-after-zero-connected
  allowance, matching CLI/one-shot construction sites.

Sergey Prontsevich 640de6562e fix(acp): add bounded wait + late-refresh for configured MCP servers
ACP entry.py fires MCP discovery in a background daemon thread, but
_make_agent snapshots tools once at build and never re-reads the registry.
Unlike CLI/TUI, ACP had no bounded wait before the snapshot and no
late-refresh for configured (config.yaml) MCP servers — a reachable-but-
slow server that finished after agent build was invisible for the whole
session.

Changes:
- acp_adapter/session.py (_make_agent): call wait_for_mcp_discovery()
  before AIAgent construction, bounded by mcp_discovery_timeout (default
  ~1.5s). A dead server can't block; servers that miss the bound are
  picked up by the late-refresh below.
- acp_adapter/server.py (_schedule_mcp_late_refresh): new method on
  HermesACPAgent — if discovery is still in flight after session creation,
  spawns an off-critical-path daemon that joins it (bounded 30s), then
  rebuilds the tool snapshot via the shared refresh_agent_mcp_tools helper.
  Cache-safe: only runs pre-first-turn (_user_turn_count/_api_call_count
  both 0); once the user has sent a message the snapshot is frozen, exactly
  as TUI PR #48403 does.
- Called from new_session, load_session, resume_session.
- Mirrors the TUI pattern (tui_gateway _schedule_mcp_late_refresh, PR
  #48403) and the CLI pattern (get_tool_definitions → wait_for_mcp_discovery).

Tests:
- Replace the AST-based test (source-text inspection) with three
  behavioral regression tests in tests/acp_adapter/test_acp_mcp_discovery.py:
  1. Blocked discovery does not block startup (non-blocking contract)
  2. Delayed discovery lands tools via late-refresh (pre-first-turn)
  3. Late-refresh is cache-safe: skips rebuild after first turn

HeLLGURD d109138ef5 fix(mcp): avoid replaying historical events on startup (#13414)
EventBridge initialized each session's last_seen timestamp to 0.0, so
the first poll after 'hermes mcp serve' starts treated every saved
user/assistant message in state.db as a fresh events_poll event.

The fix establishes a per-session timestamp baseline on startup via
_establish_baseline(), recording the latest existing message timestamp
without emitting events. Only messages written after the baseline are
delivered on subsequent polls.

Also hoists _ts_float to module-level (needed by _establish_baseline)
and adds ImportError fallbacks for hermes_constants imports so the
bridge works in environments where the module isn't on the path.

kshitij 3572d4bca1 fix(mcp): ensure MCP discovery completes before agent build in non-interactive sessions
Non-interactive sessions (hermes chat -q, hermes -z) snapshot the tool
registry at AIAgent construction time. If background MCP discovery hasn't
finished, MCP tools are invisible for the entire session — and unlike
interactive mode, there is no between-turns late-binding refresh to recover.

Root cause: wait_for_mcp_discovery() only joins an already-created discovery
thread, so it no-ops if a direct/single-query path reaches agent construction
before MCP startup created that thread. Oneshot._run_agent() didn't call it
at all.

Fix:
- Add ensure_mcp_discovery_before_agent_build() helper to mcp_startup.py:
  idempotently starts discovery if needed + bounded wait. Fail-open on errors.
- Add single_query parameter to _resolve_discovery_timeout/wait_for_mcp_discovery:
  uses mcp_single_query_discovery_timeout (default 15s) instead of the
  interactive mcp_discovery_timeout (1.5s) because one-shot sessions have no
  second turn to recover.
- Wire into CLI _init_agent (single_query from _single_query_mode flag set
  in cli.py's single-query path) and oneshot._run_agent (single_query=True).
- Interactive sessions unchanged: keep 1.5s bound (between-turns refresh covers).

webtecnica 4be138eb03 fix(config): skip URL alias without extra_headers instead of returning early (#74465)
get_custom_provider_extra_headers() was returning the result of
normalize_extra_headers() on the first matching base_url, even when
that entry had no extra_headers configured. A later providers.<name>
entry sharing the same URL but with headers set was therefore ignored.

Fix: store the normalized headers and only return when non-empty,
otherwise continue searching the remaining entries.

Eugeniusz Gilewski 64dd865912 fix(deps): repair Google transitive security floors (#72108)
Google API and authentication packages permit vulnerable httplib2 and pyasn1
transitives, while the Workspace and Google Chat runtime installers previously
treated any importable version as sufficient. Existing environments could
therefore remain vulnerable after the project dependency pins were repaired.

Carry the fixed versions through the Google and Vertex extras, lazy feature
requirements, lockfile, and both runtime installers. Route the documented
Google Chat installation path through its maintained secure requirements
instead of an unconstrained direct pip command.

Detect stale distributions, install only unsatisfied requirements, and verify
the result before continuing. Behavioral tests cover those repair invariants
without freezing manifests, lockfiles, or complete package sets.

RelaxJonh b6ca4fc856 fix(state): heal session_model_usage PK unconditionally to restore token/cost accounting
Installs whose state.db reached schema_version >= 22 before the task
dimension was added carry a 5-column PRIMARY KEY on
session_model_usage. The column reconciler ADDs task as a bare
nullable, but SQLite cannot ALTER a primary key, and the version-gated
v22 rebuild is unreachable (current_version < 22 already false), so
the composite 6-column key never lands. Every upsert in
_record_model_usage then fails with 'ON CONFLICT clause does not match
any PRIMARY KEY or UNIQUE constraint', aborting the enclosing write
transaction — token/cost accounting permanently dead (#73823).

Add an idempotent _heal_session_model_usage_pk() modeled on
_heal_gateway_routing_pk(), run unconditionally from _init_schema on
every open. Salvaged from #73838 with fix-ups:

- ported to SessionSchemaMixin in hermes_state_schema.py (the schema
  code moved out of hermes_state.py in 21c7ae8563; the PR targeted the
  old location)
- rebuild wrapped in a PRAGMA foreign_keys=OFF/ON window: the
  connection enables FKs before _init_schema and OR IGNORE does NOT
  suppress FK violations, so a single orphaned usage row (session
  pruned while accounting was broken) would have aborted the heal
- COALESCE('') on the nullable reconciler-added task column (and the
  billing columns) during the copy
- stale-v22+ regression tests: rebuilt PK + restored upsert, orphan
  rows survive the FK window, healthy-DB no-op, no legacy leftover

Dannoob 14eca89779 fix(state): retry transient 'no more rows available' across all sqlite3.Error classes
Under dual gateway/agent WAL contention (FTS5 trigram sync holding the
write lock on large appends) the SQLite engine can raise a transient
'no more rows available' error. The exception CLASS varies with the
build — some surface it as InterfaceError, a SIBLING of DatabaseError —
so it escaped both existing retry branches in _execute_write on attempt
0 and killed the turn as session_persistence_failed even though the
identical write succeeds standalone.

Port of #74934 onto the deadline-patience rewrite (8da8a7887d): the
PR's attempt-counted constants (60 retries / 300ms jitter / 2.0s engine
timeout) predate that rewrite and are superseded by the patience
budget, so they are intentionally NOT carried over. Instead the check
is message-scoped and rides the existing deadline/patience loop:

- extract the jittered-sleep-within-deadline logic into a shared
  _sleep_before_retry helper (behavior-preserving for locked/busy)
- retry 'no more rows available' from OperationalError, DatabaseError
  (checked BEFORE the FTS-corruption rebuild path so it is not
  misrouted), and a message-scoped sqlite3.Error catch-all
- any other error in any class propagates untouched on attempt 0

Tests: transient InterfaceError retried to success; unrelated
InterfaceError propagates immediately; DatabaseError variant retried;
exhausted patience surfaces the original error.

Teknium d5463e5f6d fix(agent): invalidate flush-scan cursor at the defrag marker-pop sibling site
The micro-compaction defrag pass (_defrag_rolling_summary) rewrites the
newest MICRO marker's content and pops _DB_PERSISTED_MARKER from the
LIVE dict in place — the same in-place pop class finalize_turn's fill
site was fixed for in #75170. Without invalidation the bounded
flush-scan cursor identity-skips the rewritten marker row and the
defragged rolling summary never reaches state.db (resume rehydrates a
stale summary).

The compressor holds no agent reference, so the pop site raises
_flush_scan_cursor_invalidated and the finalize_turn micro-compaction
block consumes it, setting agent._db_flush_scan_prefix = None.

The module-scope pop sites (context_compressor.py:175/224) operate on
fresh copies — identity-breaking by construction — and need no flag.

Follow-up to #75170 (fix-the-class sweep of _DB_PERSISTED_MARKER
in-place pops).

spfcraze 2aaeee2ee5 fix(agent): invalidate flush-scan cursor when finalizer pops db marker
The bounded flush-scan in _flush_messages_to_session_db_unlocked skips
the identity-matched prefix of its previous snapshot, on the documented
assumption that no code path pops _DB_PERSISTED_MARKER from a live dict
in place. finalize_turn's pure-tool-call-tail fill is exactly that path:
it pops the marker so the filled content gets re-persisted — but the
cursor then skips the row anyway, so the delivered final response never
reaches state.db and /resume replays content="" (the #43849/#44100
class resurfacing via the perf cursor). Invalidate the cursor at the
pop site so the filled row is re-examined.

Brooklyn Nicholson 609cd28b17 feat(tui): rank the slash menu by the skills you actually use
The `/` menu was a flat first-30 slice of the completer's output, and the
completer emits every registry command before the first skill. On a
230-skill install that meant a bare `/` filled all 30 rows with commands
and offered no skill at all, while `/p` cut off inside the alphabetical
skill block — dropping /proving-a-fix-works (471 invocations) and
/pr-update (160) but keeping /pretext (2).

Spend the limit per kind and rank the skill block by recorded usage
(the same .usage.json count Capabilities shows), most-used first and A-Z
within a tie. A bare `/` is browsing, so bundled skills that shipped with
Hermes and were never opened are dropped as noise; a typed query is a
search, and a search that hides a match is broken, so there nothing is
pruned and the ranking only reorders. An argument stage keeps the order
its own command chose.

Teknium 3b9cf56aff fix(agent): exclude reasoning_details envelope from tail-budget walk (#73298)
Companion to the preflight fix: _estimate_msg_budget_tokens charged
reasoning_details at chars/4 via _REPLAY_BUDGET_KEYS, so the signed/base64
envelope (measured 72% of the reasoning mass on Anthropic-wire sessions)
consumed the tail budget and _find_tail_cut_by_tokens summarized away real
transcript to make room for tokens that are never sent (69 messages on the
measured session; up to ~4.8x budget inflation on thinking-heavy histories).

Per the #51800 counter-argument, actual thinking TEXT stays visible to the
budget: _reasoning_details_text_chars counts thinking/text/summary fields
and skips signature/data/encrypted blobs, and the text is skipped entirely
when reasoning/reasoning_content already carries the identical prose (so it
is charged once, not twice). codex_reasoning_items remains fully charged —
Codex Responses genuinely replays it every request (#55572).

Sabotage-verified: restoring reasoning_details to _REPLAY_BUDGET_KEYS fails
the new envelope and double-charge tests.

Fix-up for the cherry-picked cooldown persistence: the PR's tests mocked
the DB (SimpleNamespace(_db=MagicMock())), which cannot prove the cooldown
survives a restart. Replace with the production shape — a real SessionDB

regression: fail a hygiene compression on runner #1, tear it down, build a
fresh GatewayRunner on the SAME database, and assert the cooldown is still
honored (no compression agent instantiated). Also updates the timeout test
to assert the DB-backed record_compression_failure_cooldown write instead
of the removed in-memory dict.

When a short conversation ends in a tool-call/result group and the

_find_tail_cut_by_tokens() could return len(messages) + 1. This
happened because the final return used max(cut_idx, head_end + 1)
which could push past the array length when head_end >= len(messages).

The out-of-range value then propagated into _find_context_summaries()
which iterated range(start, end) and indexed messages[idx] without
clamping, raising IndexError and failing the active gateway turn.

## Fix

Two-layer defense:
1. Source fix: _find_tail_cut_by_tokens() now clamps its return to
   min(n, ...) so it never exceeds len(messages).
2. Defensive clamp: _find_context_summaries() now bounds start/end
   to [0, len(messages)] so even if a future caller passes bad values,
   it cannot crash.

## Verification
- 7 new regression tests for the exact boundary conditions
- All 214 existing test_context_compressor.py tests pass

Yuanang Yang b5ca19118e fix(mcp): guard against duplicate spawns and stale connecting entries (#58862)
Three fixes for concurrent MCP server spawn races in register_mcp_servers()
and discover_mcp_tools():

1. register_mcp_servers: add k not in _server_connecting guard to the
   new_servers filter. Without this, a concurrent second call sees the
   same servers as 'new' and spawns duplicate stdio subprocesses.

2. discover_mcp_tools: same _server_connecting guard in the
   new_server_names filter. This entry point is called from CLI, TUI,
   gateway, and cron — any two racing would double-spawn.

3. Stale _server_connecting cleanup on TimeoutError/InterruptedError.
   When _run_on_mcp_loop times out or is interrupted, _discover_all's
   gather may not have finished, leaving entries stranded in
   _server_connecting that block future reconnection attempts. The
   cleanup clears only entries added by this call (not external ones),
   logs a warning, and records connect errors.

Salvage of #58879 by @nanami7777777 (superset of #58867 by @liuhao1024).

Israel Lot 5c45d9c208 fix(agent): mirror substitute_api_content's guard in the estimator shadow
Review follow-up on #75102. The shadow substituted the sidecar whenever
the ``api_content`` key was merely PRESENT, but the wire only substitutes
a non-empty string sidecar on a user/assistant row (see
``turn_context.substitute_api_content``). For any other shape the sidecar
is popped and discarded while the clean ``content`` is sent -- so the
shadow dropped real content from the estimate and UNDERcounted, the
dangerous direction: compaction fires too late and the turn dies on a
hard context-length error instead of merely compressing early.

Gate the substitution on the same predicate, and cover the divergent
shapes (None, empty string, int, list, non-user/assistant role) with a
test that fails against the unconditional version.

Also rename the image test: it never carried a sidecar, so it was not
testing what its name claimed. It is a non-regression pin on the flat
per-image accounting that moved into ``_wire_message_shadow()``, and is
now named for that.

Israel Lot e3bc517034 fix(agent): stop double-counting api_content in the token estimator
`api_content` is a SUBSTITUTE for `content`, not an addition to it.
`turn_context.substitute_api_content()` pops the sidecar and overwrites
`content` at every API-bound message-build site (the `api_messages` build
in `conversation_loop`, the max-iterations summary in
`chat_completion_helpers`, the chat-completions transport), so exactly one
of the two is ever sent to the provider.

The preflight estimator counted both, because both `_estimate_message_chars`
and `_estimate_message_tokens_without_images` walked every key of the
persisted dict with a single-entry denylist (`_anthropic_content_blocks`).
Any message whose sidecar differs from its clean stored content was counted
twice — exactly 2.00x on a 40KB sidecar.

The sidecar exists to keep the provider prompt-cache prefix byte-stable, so
it is written on precisely the long, cache-pinned messages where the
doubling hurts most. Because `estimate_messages_tokens_rough()` also feeds
the compaction threshold via `context_compressor` and `conversation_loop`,
the inflated estimate makes compression fire on phantom bytes.

Fix: substitute rather than sum, mirroring the wire. The two estimator
helpers had drifted into near-identical copies of the same shadow-building
loop, so this factors the shared logic into `_wire_message_shadow()` and
fixes the class once instead of patching one site and leaving the other.

Image accounting is unchanged: base64 payloads are still replaced with a
placeholder and charged at the flat `_count_image_tokens` rate, and the
`_multimodal` text_summary path is preserved.

Tests: three cases in `TestEstimateMessagesTokensRough` — sidecar equal to
content is counted once, a sidecar that DIFFERS is still counted (a lower
bound, so it fails if the field were dropped rather than substituted, which
would undercount the real request), and a sidecar cannot smuggle raw base64
past the flat image rate.

Verified on Linux (Python 3.11): 53 passed in
tests/agent/test_model_metadata.py, 57 passed with
tests/agent/test_context_breakdown.py, 656 passed / 3 skipped across the
compression/context/token/estimate/prune surface of tests/agent.
Mutation-tested: reverting the substitution fails the new equality test.
`scripts/check-windows-footguns.py` is not applicable — no file I/O,
process management, terminal handling, subprocesses, or signals.

Teknium fae0c4f5f4 fix(hindsight): create embedded profile env file owner-only (0600)
The embedded Hindsight daemon's profile env file carries the plaintext
HINDSIGHT_API_LLM_API_KEY but was written via bare write_text(), leaving
it with umask-derived (typically world-readable) permissions.

- Create/truncate the file via os.open(..., 0o600); chmod a pre-existing
  file to 0600 BEFORE writing new secret bytes.
- Post-write validation on POSIX: verify 0600, retry chmod, and raise if
  the file still isn't owner-only.
- If validation fails, unlink the secret file so a plaintext key is never
  left behind with unverified permissions.
- Regression tests under tests/plugins/ for fresh-write mode, tightening a
  pre-existing 0644 file, and cleanup on validation failure.

Narrowed reimplementation of #74236 confined to plugins/memory/hindsight/;
the core utils.py atomic-replace opt-out from the PR was dropped.

Teknium ee5a66ae3e fix(distribution): path-aware allowlist; preserve legacy copy-everything when omitted
Follow-ups to the previous commit (#74414 by @webtecnica, re #74373):

- When distribution_owned is OMITTED, restore the legacy contract: every
  staged entry outside USER_OWNED_EXCLUDE is copied. The cherry-picked
  filter consulted owned_paths(), which silently narrowed omitted-list
  distributions to DEFAULT_DIST_OWNED and dropped undeclared payload
  (extra top-level files/dirs existing distributions legitimately ship).
- Make explicit allowlists path-aware so documented nested entries like
  skills/research/ and cron/digest.json select exactly that subtree/file
  instead of being dropped by the top-level name comparison. Traversal
  segments (.., absolute) and USER_OWNED_EXCLUDE roots are still rejected.
- Regression tests: omitted-list legacy behavior + nested-path allowlist.

webtecnica a42e3e8ba4 fix(distribution): respect distribution_owned allowlist in _copy_dist_payload
_copy_dist_payload() in profile_distribution.py iterated all staged
entries without consulting the manifest's distribution_owned allowlist,
so manifests that restricted distribution_owned only had cosmetic effect.

Fix: compute manifest.owned_paths() at the top of _copy_dist_payload()
and skip entries not in that set, after the USER_OWNED_EXCLUDE check.

The owned_paths() method already existed on DistributionManifest and
correctly falls back to DEFAULT_DIST_OWNED when no explicit
distribution_owned is set, so the new filter preserves backward
compatibility for existing manifests.

Teknium a0b29343b4 fix(gateway): offload preflight-compression warning enrichment; behavioral offload tests
Follow-ups to the previous commit (#74155 by @Drexuxux):

- enrich_model_switch_warnings_for_gateway() -> merge_preflight_compression_warning()
  still called the sync resolve_display_context_length() provider probe ladder
  inline in both async /model call sites; dispatch it via asyncio.to_thread.
- Replace the inspect.getsource() test (source-reading tests are banned by
  AGENTS.md) with behavioral tests that drive the real _handle_model_command:
  assert the resolver runs off the loop thread and that the warning enrichment
  is dispatched through asyncio.to_thread.

Drexuxux 95eae03883 fix(gateway): offload /model context-length resolution off the event loop
resolve_display_context_length() runs two blocking chains: the route
comparison in should_clear_context_pin() and the provider probe ladder in
get_model_context_length() (blocking requests calls to Anthropic /v1/models,
Copilot, Nous, Codex, GMI, Ollama, models.dev and OpenRouter).

The gateway message path already offloads both via
get_model_context_length_async() and should_clear_context_pin_async(), but
the /model slash-command handlers (_handle_model_command, _finish_switch)
called the sync helper directly, freezing the whole event loop for the
duration of the probe ladder - no messages processed on any platform, and
the Discord heartbeat timeouts that get_model_context_length_async() was
introduced to prevent.

Add resolve_display_context_length_async(), a thin asyncio.to_thread wrapper
mirroring the two existing *_async helpers (no logic duplication), and await
it at both handlers.

Chen Jin 4aa029bfab fix(install): expose hermes-agent and hermes-acp launchers on PATH
setup_path() only wrote a 'hermes' launcher into the command-link dir,
even though pyproject.toml declares three [project.scripts]:
hermes, hermes-agent (run_agent:main), hermes-acp (acp_adapter.entry:main).

Fresh venv installs (the common case on macOS/Linux) leave
~/.local/bin/{hermes-agent,hermes-acp} empty, so external tools
expecting 'hermes-acp' as a standalone command (documented as
first-tier supported in website/docs/user-guide/features/acp.md)
fail to find it after a fully successful install.

Loop over the three console-script names, writing a shim per entry
that exec's the venv interpreter with the right checked-in
entrypoint. --no-venv keeps the old single-shim behaviour since
it does not manage the venv and only 'hermes' is guaranteed on PATH.

Drexuxux 4a1bff642a fix(cli): heal a bare custom provider to its config key, not its display name
7b5a18817 migrated the sibling slug sites to custom_provider_slug, which
keeps a keyed providers: entry's config key as its durable identity. It
covered find_custom_provider_identity_by_model; canonical_custom_identity's
third recovery source - the configured-provider fallback - still built
f"custom:{normalized}" out of whatever string the caller happened to hold.

_get_named_custom_provider matches on either spelling, so a display name
that differs from its config key matches the entry and then heals to
custom:<display-name>. That is a second identity for one endpoint: the
endpoint- and model-based sources of the same function return
custom:<config-key>, and so does everything that persists or restores a
session's provider override. canonical_custom_identity exists precisely to
make a bare "custom" routable again, and tui_gateway calls it on the
session-persist, resume and recovery paths - so the divergence lands in
stored session identity.

Re-resolve through the endpoint the matched entry owns, reusing the
function's own URL-based canonicaliser rather than duplicating the match
logic. Legacy unkeyed custom_providers: entries keep their name identity,
and an unconfigured candidate still returns None.

Drexuxux 57a807373d fix(telegram): send_image uploads still went out on the short read timeout
524ab5399 widened the media read timeout from send_video to "all upload send
paths" - send_voice/send_audio/send_photo/send_document/send_media_group/
send_animation. Both send_photo calls inside send_image() were missed, so
they still ran on the short timeout the rest of the Bot API is tuned for
while the sibling media paths already pass it.

The missed pair is the worst one to miss: send_image tries a URL send first,
then falls back to downloading the image and uploading the bytes - the path
documented as "supports up to 10MB", i.e. the slowest send in the file and
the one whose server-side processing wait most often outlasts the short
budget. When it times out the handler's last resort posts the bare URL as
text, so the picture silently never arrives as a picture.

Pass _MEDIA_SEND_READ_TIMEOUT on both, covered by two behavioral tests that
drive send_image for real - the URL send and the forced byte-upload fallback
- and assert the read_timeout that actually reaches the Bot API.
