Salvaged from PR #97815 by @itsflownium, slimmed to the schema-free core:
- TodoStore gains a monotonic in-memory revision; the todo tool result
returns it so clients can reject stale updates
- tui_gateway emits a dedicated todo.updated full-snapshot event that
bypasses optional tool-progress display settings
- session resume/activate responses attach the authoritative todo
snapshot; renderer restores it with revision arbitration
- desktop store tracks per-session revisions and rejects regressions
The session_todo_state DB table from the original PR is intentionally
dropped: canonical todo tool results already persist in conversation
history, so resume paths derive the snapshot from the stored transcript
instead of a parallel store.
_runtime_model_config merges the agent's current identity onto the row's
existing model_config JSON. For model and provider it only SET the key
when the agent attribute was truthy, while base_url/api_mode/
reasoning_config/service_tier already deleted stale values when falsy.
When an agent rebuilt with an empty provider (inheriting the profile
default) was persisted, the previous provider/endpoint survived in
model_config while _persist_live_session_runtime updated the model
column separately. Resume then read the fresh model from the column but
the STALE provider from model_config, silently routing the resumed chat
to the wrong endpoint (e.g. a VeniceAI/empero route under a model that
should run on the profile default).
Apply the same delete-on-falsy rule to model and provider, mirroring the
or-None deletion the CLI path (_persist_model_switch_to_session) already
uses, so a stale session state can never survive into a resume override.
Existing desynced rows self-heal on the next live metadata persist.
Adds regression tests: merge drops stale provider/model when the agent
attribute is falsy, a truthy provider overwrites the stale value, resume
overrides fall back to the billing provider instead of the stale
endpoint, a real-DB round trip heals an already-desynced row, and a
first write (existing=None) reflects only the agent's current identity.
Bot Chats created before the follow_profile_config marker existed carry no
contract in model_config, so they would stay pinned to a stale stored
provider until deleted — the exact shape of the live reports (#89497,
#94818). Mirror the plugin's own identity rule (the profile's session
titled exactly 'Bot Chat') as a legacy fallback in
_stored_session_runtime_overrides, matching the room-plumbing legacy
'Group:' title fallback.
Follow-up to the salvaged #90343 (@curator8888) and #96111 (@lorzl).
Bot-Mode canonical chats (the ONE forever DM per bot) and room plumbing
sessions are plugin-owned scratch conversations. They are now created with
an explicit follow_profile_config contract, persisted in the session row's
model_config, so session.resume rebuilds from the member profile's CURRENT
config instead of restoring the stored model/provider pin from an old row.
That stale pin is what left bot DMs stuck on a dead provider (e.g. 'out of
Nous credits' after the profile was switched to ollama-cloud) while the
same bot worked fine in rooms — the mirror image of the room-plumbing bug
(#89497 class). Normal 1:1 user chats keep the stored-runtime restore:
opening an older chat must show the model it actually used.
- tui_gateway/methods_session.py: accept follow_profile_config on session.create
- tui_gateway/server.py: persist the marker in the row; skip stored-runtime
overrides on resume when present
- apps/desktop/src/plugins/hermes-bots/plugin.js: send the contract from
createCanonicalChat and ensureGroupChatSession
- tests: backend override + row-persist coverage; desktop source-contract
coverage for both session kinds
Room member sessions in Bot Mode are per-member scratch conversations
inside a group chat. session.resume restored their stored model/provider
pin from the row's model_config, so a room bot stayed stuck on whatever
provider was pinned when the row was first written — even after the
profile was switched. Every room message then failed on the stale
provider (e.g. 'out of Nous credits' after switching a profile from
Nous to ollama-cloud) while the same bot worked fine in DMs.
Add an explicit room_plumbing contract:
- session.create accepts room_plumbing: true, persisted in model_config
- _stored_session_runtime_overrides() returns {} for marked rows, so a
room session always rebuilds from the member profile's CURRENT config
- hidden + 'Group:' title shape is kept as a legacy fallback for rows
created by older desktop builds that never sent the marker; hidden
non-room chats keep the stored-runtime restore
- Desktop Bot Mode sends room_plumbing: true when creating the hidden
per-member room sessions
Fixes#89497
A session row persists the provider identity a chat actually used. When that
provider is later renamed or removed (e.g. a custom_providers:/providers:
entry deleted, or a provider renamed oldone->newone), Desktop/TUI resume
restores the stale name into agent init and dies with:
agent init failed: Unknown provider '<name>'
while the CLI resumes the same session fine with the configured default.
- runtime_provider: add is_routable_provider() (full resolution chain:
built-in -> providers: -> custom_providers: -> models.dev)
- _stored_session_runtime_overrides: heal a non-routable provider via
canonical_custom_identity (base_url -> model -> configured provider),
drop to the configured default when unrecoverable, and clear the stale
base_url after healing so a dead endpoint cannot override the registry URL
- _start_agent_build: gate deferred-resume overrides on provider routability;
when the stored provider is gone, prefer the model the user picked for THIS
session, else the configured default
- tests: is_routable_provider cases, heal/fallback round-trips, gate checks

Independent review finding on the merged #95980:
_apply_live_compression_config only acted on PRESENT keys, so removing
tail_mode / model.context_length / target_ratio / model_thresholds /
proactive_prune_* / protect_last_n / min_tail_user_messages / threshold /
idle_compact_after_seconds from config.yaml left stale values active in
live sessions forever (probe-verified: all six stale after applying
empty mappings).
Absence now restores the normalized default — or the model-derived
value — through the SAME derivation the construction path uses:
- ContextCompressor ctor defaults read off its real __init__ signature
(no hardcoded copies to drift)
- compression.threshold removal re-derives via agent_init's
_resolve_compression_threshold (Codex gpt-5.4/5.5 + spark autoraise
included)
- model.context_length removal drops the config override and forces
re-inference through the deferred get_model_context_length resolution,
which also re-applies the small-context threshold floor
- model_thresholds removal clears stale per-model overrides from the
live threshold; tail_mode falls back to the ctor's 'lean' (the old
present-key path normalized invalid values to 'legacy', diverging
from the compressor's own fallback)
Also fixes proactive_prune_min_reclaim_tokens's present-but-null default
(was 0; the real default is 4096).

A hermes serve killed mid-update lost every un-flushed in-memory session
(#94724 item 2, reported by @ruangraung): the next RPC failed with
'session-scoped RPC rejected: not in memory (detached/reaped runtime)'
and no store held the transcript. #95576 made serves survive future
updates; this closes the kill path itself:
- install chaining SIGTERM/SIGINT handlers (hermes serve / dashboard
startup, before uvicorn's capture_signals) that first persist
in-memory session transcripts to state.db — bounded by
HERMES_TUI_EXIT_FLUSH_BUDGET_S (default 5s, daemon worker + join) so
a hung SQLite write can never block exit
- _shutdown_sessions (atexit) runs the same bounded flush FIRST, before
the slow per-session teardown a supervisor may SIGKILL mid-way
- the idle-reaper scan piggybacks a periodic incremental flush
(marker-deduped agent._persist_session, running sessions skipped) so
even a SIGKILL loses at most one flush interval — no new timer
subsystem
Refs #94724
Sibling site of the same class fixed in the previous commit: a failed
profile-store open during _init_session fell back to _get_db(), hydrating
and persisting a named-profile session's cwd row against the launch
state.db. Fail closed instead — skip the hydration (log a warning) so
nothing ever reads or writes the wrong profile's store. The other
profile-store open sites (_db_for_profile, _ensure_session_db_row,
_session_db) already degrade to None/skip and were left as-is.
A deferred agent build for a named-profile session swallowed a failed
profile-store open (except Exception -> session_db = None), so _make_agent
silently bound the launch _get_db() handle and every turn bled into the
wrong profile's state.db exactly when the profile store was briefly
unopenable. Opening the named profile then looked blank.
Route the open through _open_profile_session_db, which raises a clear
'profile session store unavailable' error instead; the deferred build's
existing except path turns that into agent_error + an error event, so the
user gets a clear failure and no agent turn against the wrong store.
Salvaged from #90219 (hardening half), adapted to main's current
deferred-build/_transfer_db_to_agent structure.
Related to #87723 and #89789. #88532 covered SessionStore only.
* fix(tui_gateway): ask before queueing a guarded model picked mid-turn
config.set model on a running session cannot swap the agent in place, so it
stashes the pick in session["pending_model_switch"] and applies it at the
next turn start. That branch answered confirm_required=False without ever
running the selection guards.
A client that implements the confirm round-trip was therefore told no
consent was needed and never prompted. One turn later
_apply_pending_model_switch ran the guards with the stashed (unconfirmed)
flag, saw the warning, and dropped the switch by design. The model reverted
with no confirm ever offered, because the only moment a round-trip was
possible had already passed.
Evaluate the guards before stashing, where the client still has a live
response to turn into a prompt. Nothing is queued for an unconfirmed
guarded pick, so the session is left exactly as it was and the re-send
carrying confirm_expensive_model queues it for real. The apply-time check
stays as the backstop for guards that can only decide after resolution.
The data-policy guard keys on the model id alone, which is all this branch
can see before resolution. The cost guard returns None when pricing is
unknown and its models.dev lookup is allow_network=False, so calling it
early can only under-fire and never blocks the RPC thread.
* test(tui_gateway): pin provider forwarding, name the canonical confirm field
Two review follow-ups, no behavior change.
_pending_switch_selection_warning forwards `provider=provider or None`, but
nothing asserted it: a guarded model id fires the data-policy guard on the
model alone, so the existing tests passed with `provider` dropped entirely.
Record the kwargs instead. Dropping the argument fails the first test;
removing the `or None` normalization fails the second.
The confirm responses carry `warning` and `confirm_message` with identical
text, which reads like an accident. Name which one clients should read
(`confirm_message`; `warning` is the pre-confirm-era alias that
_apply_pending_model_switch already treats as a fallback) so the two do not
drift apart later.
Both raised by @Enough1122 in review.
The composer status stack polls `process.list` every 5s while a background
process row is on screen. `process.list` is session-scoped, so against a
runtime id the gateway no longer holds it returns 4001 "session not found".
`refreshBackgroundProcesses` swallowed *every* failure with a bare `catch {}`
commented "transient socket loss". A gone session is not transient: the poll
re-sent the same dead runtime id every 5 seconds for the lifetime of the
window. On one machine this produced 31,518 gateway rejections in a day
(vs 663 the day before), 18,614 of them against a single runtime id, and it
is what users see reported as "sessions stopped with a session not found
error" after an update.
The trigger is a reconnect, not the poll itself: anything that mints a fresh
runtime (gateway restart, the #94219 reconnect/replay work, an idle-reaped
pooled backend) strands the id the status stack is still holding, and nothing
in this path ever re-checked it.
Distinguish the two failure classes:
- 4001 / "session not found" is TERMINAL for that runtime id — latch the id
and stop polling it.
- A timeout or transport error is transient — keep retrying, since the
session may well still be alive. Misclassifying that direction would
silently freeze the status stack on a healthy session.
The latch is cleared when the status stack (re)binds a session id, so a
session that comes back under a fresh runtime resumes polling normally
rather than staying dark for the life of the app.
Also name the method in the gateway's 4001 warning. That line was added in
c305839442 "for diagnosability", but without the RPC name it cannot say WHICH
client call is looping — the reason this storm could not be attributed from
the logs alone. A ContextVar set in `handle_request` carries it; it is
diagnostic only and never used for authorization.
Tests:
- composer-status: 4001 stops the poll, a timeout does not, one gone session
never suppresses a healthy sibling, and a rebind resumes polling.
- tui_gateway: the rejection warning names the method.
Chat/event-plane quality work for the amended Phase 1 scope of #94484
(maintainer restructure: lean chat/event plane, no control-plane
changes). Three fixes came out of a source-level comparison against
OpenHands, Chainlit, VS Code, Zed, LangGraph, and Goose.
1. Per-turn trace_id + active-turn telemetry: _start_inflight_turn mints
a 12-hex trace_id; _event_frame stamps it on every event frame in the
turn, so a client can correlate the full lifecycle (dispatch -> first
token -> tool calls -> complete) from one identifier — none of the six
surveyed projects has frame-level turn correlation.
session.events.stats now reports active_turns (session_id, trace_id,
elapsed_s, streaming).
2. Transient vs durable events (OpenHands StreamingDeltaEvent pattern):
message.delta / thinking.delta are stamped with seqs (live ordering
holds) but never buffered — one streaming turn emitted hundreds of
delta frames and evicted every durable control event from the
512-slot ring, defeating replay for the exact reconnect window it
exists to cover. The ring now evicts manually and records the highest
DURABLE seq dropped, so truncated means real data loss and delta-only
gaps no longer false-positive.
3. Seq-namespace epoch (Goose stale-cursor recovery): event_replay.EPOCH
(8-hex per boot) is announced in gateway.ready and echoed by
session.events.since; the client drops its seq watermarks when the
epoch changes, so a stale HIGH watermark from a previous gateway
process can no longer suppress replay/gap-detection forever. Legacy
backends without an epoch are unaffected (client keeps watermarks).
Validation: Python 85/85 across replay/entry_ws/keepalive/protocol
(12 replay tests, 3 new); vitest 9/9 shared (2 new epoch tests), 66/66
desktop; full tui_gateway sweep 614/615 (1 known ordering flake, passes
in isolation). Live e2e on this tree: 12-event turn -> seqs contiguous
1..12, 8 durable frames buffered + 4 deltas live-only, single trace_id
on all frames, active_turns elapsed_s matches the real turn duration.
Research provenance: NousResearch/hermes-agent#94484 (comparative-scan
comment); techniques credited to OpenHands (transient split), Goose
(epoch/stale-cursor), per maintainer-restructured plan.
The function _persist_live_session_system_prompt runs on the RPC
dispatcher thread. A model switch calls it. On that thread the
_SESSION_CWD contextvar is not set. Because of this,
resolve_agent_cwd() falls back to the process TERMINAL_CWD value.
The desktop pins TERMINAL_CWD to the home directory. The rebuilt
prompt then records the home directory as the working directory.
The wrong prompt persists to the session database. Later turns
restore the stored bytes without change, because the turn prologue
rebuilds the prompt only when the cache is empty. The wrong line
never heals. The terminal tool is not affected, because it reads
the per-session cwd record.
The desktop composer sends a model switch before the first turn
when its model differs from the config default. Because of this,
a new project session can show the wrong working directory for
its full life.
Fix: bind the session context around the rebuild, in the same way
the function already binds the profile home for issue #50233. The
test drives the real function from a bare thread and asserts the
persisted prompt carries the session cwd.
The desktop app spawns `hermes serve --ws-only` instead of `hermes serve`.
The slim server (tui_gateway/entry_ws.py) uses the bare websockets library
to call handle_ws directly — same dispatch surface, same 158 RPCs, same
events, zero HTTP framework. tui_gateway.server has zero FastAPI imports;
the slim server never touches web_server.py (19.8K lines) at all.
Full backward compat: older runtimes strip --ws-only and fall back to
regular serve (still headless, just through uvicorn).
Server: per-session monotonic seq on every routed event frame, bounded
512-frame replay ring (64 sessions, FIFO eviction), plus two new RPCs —
session.events.since (replay newer-than-watermark, reports latest_seq +
truncated so clients detect gaps) and session.events.stats (telemetry).
Client: per-session seq watermarks recorded from live frames; after any
successful reconnect a fire-and-forget fetchReplay() drains missed events
through the normal dispatch path (recordSeq ignores non-increasing seqs,
so stale replay can never regress a watermark); focus-triggered reconnect
nudge in use-gateway-boot for the Electron unfocused case where macOS wake
skips visibilitychange.
Replay failures are swallowed by design: lossless resume is an upgrade
over the previous lossy reconnect, never a new failure mode.
macOS sleep/wake (or a silent network drop) can leave the renderer's
WebSocket half-open: no close event fires, so connectionState stays
'open' while every RPC hangs until its per-call timeout. prompt.submit's
timeout is 30 minutes, so the user's next message reads as "enter does
nothing until I restart the app".
- Add a minimal ping RPC (tui_gateway/server.py) answered synchronously
on the WS reader thread.
- On wake signals, reconnectNow now probes the open-looking socket with a
5s-bounded ping and force-closes it on failure, letting the existing
reconnect machinery (backoff, tile rebinding, session refresh) take
over. A pre-ping backend answering -32601 is treated as healthy.
- Tests: half-open socket force-reconnects; healthy socket untouched;
method-not-found backend untouched; backend ping envelope contract.
Reimplements the concept from #77129 on the current structure (viewer
rebinding from #83716 and _client_gone_interrupt_requested clearing are
preserved).
_close_sessions_for_transport snapshots owned sessions under
_sessions_lock, then wrote session['transport'] = _detached_ws_transport
WITHOUT re-checking that the session still pointed at the disconnecting
transport. A session.resume that rebinds the session to a new live
transport between the snapshot and the stomp got knocked back onto the
drop sentinel with an orphan-reap Timer armed against a client that is
attached right now.
The park now happens under _sessions_lock and first revalidates
ownership: if the session already moved to a different live transport,
the disconnect has nothing to tear down — skip the sentinel park AND the
reap scheduling. Regression test simulates the rebind landing between
snapshot and stomp.

Follow-up to the #65422 salvage:
- startup_orphan_reap joins _RECOVERABLE_END_REASONS (kept distinct from
ws_orphan_reap for forensics): every recovery fence
(find_latest_gateway_session_for_peer, unarchive_recoverable_session,
promote_to_session_reset) now treats a startup-swept row as an
accidental end, so a sweep never makes a session unresumable.
- Config key moves from sessions.orphan_reaper to
dashboard.startup_orphan_sweep in DEFAULT_CONFIG, next to its siblings
ws_ping_interval / ws_ping_timeout / ws_orphan_reap_grace_s; the raw
loader in tui_gateway.server reads the new key (fail-open on missing).
cli-config.yaml.example and website/docs/user-guide/configuration.md
follow the dashboard.* documentation pattern.
- New regression test: a stranded 'active' row (ended_at NULL, no live
runtime) is swept AND still recoverable via peer-keyed lookup and fully
revivable via reopen_session afterward.
Close session rows left ended_at IS NULL when the in-process websocket
orphan timer dies with the process (#65194). Dual-clock staleness
(started_at AND newest message), desktop included, live in-memory
sessions excluded, scheduled once from both entry.main and the WS
sidecar so desktop/dashboard boots also run the sweep.
Messages sent into a session whose in-memory runtime was detached on WS
disconnect and orphan-reaped vanished silently: _sess_nowait returned
4001 with no log line, so 'request arrived and was rejected' was
indistinguishable from 'request never arrived' in a 'message vanished'
report. Log a WARNING with the session id and request id on every
session-scoped RPC rejected against an unknown runtime id.
Adds a regression test asserting the 4001 response and the warning.
Closes#90428
- New dashboard.ws_ping_interval / dashboard.ws_ping_timeout defaults
(20.0/20.0) in DEFAULT_CONFIG; hermes_cli/web_server.py reads them for
non-loopback binds. Loopback keeps ws_ping=None (event-loop stalls must
never kill a healthy local connection).
- New dashboard.ws_orphan_reap_grace_s (20.0): tui_gateway/server.py's
_WS_ORPHAN_REAP_GRACE_S now resolves from config via
_resolve_ws_orphan_reap_grace(); the HERMES_TUI_WS_ORPHAN_REAP_GRACE_S
env var is kept as an internal override for backward compat and wins
when set.
- tests/test_ws_keepalive_config.py: real load_config against a temp
HERMES_HOME yaml — defaults, propagation, deep-merge, env override,
invalid-value fallback.
Storm killer for the reap->broadcast->auto-re-resume feedback loop:
- New _pending_ws_reaps registry (sid -> Timer): _schedule_ws_orphan_reap
registers, _reap pops, and _cancel_ws_orphan_reap(sid) is called from
every resume/reuse/rebind path — the session.resume fast-path reuse
(methods_session.py), _claim_or_reuse_live winners, and the
_live_session_payload live-transport rebind.
- When a resume mints a fresh runtime for stored session id S, any prior
runtime for S still parked on the detached-WS sentinel is claimed under
the resume lock, its reap Timer cancelled, and the record finalized
quietly with end_reason superseded_by_resume — NOT in
_RECLAIM_END_REASONS, so no session.reclaimed broadcast fires and the
client's auto-re-resume can't storm.
- superseded_by_resume added to _RECOVERABLE_END_REASONS in
hermes_state_common.py so canonical Bot Chat resurrection still applies.
Unit tests: resume cancels the reap timer, superseded runtimes finalize
without a reclaimed broadcast, and the normal orphan reap still fires
when nobody re-resumes.
Live sessions hold one transport; a pop-out window's session.resume
rebinds it, and on pop-out close the disconnect path parked the session
on the drop sentinel — the original window never received stream events
again until a manual re-resume (#83716).
Sessions now track every transport that has shown them (viewers, stamped
in _live_session_payload). _close_sessions_for_transport re-binds to the
most recent surviving viewer instead of detaching when one exists; dead
viewers are filtered; the drop sentinel + grace reap remain the path for
the last viewer. Root cause and repro by CharlesR-sudo on #83716.
If an interrupted turn never settles (agent thread hung in a syscall,
supervisor lost), the 1s poll chain rescheduled forever — trading the old
leak-one-worker bug for leak-one-session-plus-timer-chain. After
_WS_ORPHAN_INTERRUPT_REAP_MAX_POLLS (60 = ~60s, 3x the default grace) the
reaper logs loudly and force-reaps, mirroring the pre-existing stuck-running
safety net's deadlock-breaking role. Focused suite 4 passed, 1 skipped.
After the existing reconnect grace, route a still-detached running session through the same interrupt mechanism as session.interrupt. Preserve delegation deferral, sidecar teardown, partial history, and single-owner reap semantics.
Verified on upstream main: RED 4 failed/2 passed without production changes; GREEN 603 related gateway/compute-host tests. Ruff and py_compile passed. Momus pass 2: APPROVE.
The grace timer treated mid-turn detached sessions as not-orphaned and
returned without arming another timer. Eviction paths also skip
running sessions, so the in-memory agent leaked until process restart.
Fixes#85578
/review takes the last 10 chat messages plus optional instructions,
spawns a full-privilege background subagent (the async delegation
rail) that investigates the referenced work (PR, code, docs), and its
complete review re-enters the spawning session as a normal
async-delegation completion the primary agent can act on.
- agent/review_engine.py: shared engine (snapshot, briefing,
auxiliary.review credential resolution, dispatch, note formatting)
- tools/delegate_tool.py: internal credentials_cfg per-call override
(never model-facing) resolved through the same credential system as
delegation.provider pins
- auxiliary.review config block (provider/model/base_url/api_key/
api_mode); provider auto + empty model = inherit the main model
- Surfaces: CLI process_command, gateway run.py dispatch +
slash_commands handler (binds the approval session key so the
completion routes back), TUI/Desktop live dispatch in
tui_gateway/server.py, CommandDef registry (+Slack /hermes-only cap)
- Docs: delegation.md section + slash-commands.md (both tables)
- Tests: 15 engine tests (sabotage-verified: credentials_cfg and
dispatch tests fail without the fix), 4 gateway handler tests
through the real async rail
Cross-connection DMs were pure polling: the Desktop drains every gateway's
bot_relay outbox on a 4s interval, so each hop eats up to 4s outbound plus
4s for the reply leg (#92760 'bots reply slowly').
Emission point: the gateway's existing change watcher (_CHANGE_WATCHES in
tui_gateway/server.py). Envelopes are written by the AGENT process
(message_agent -> tools.bot_relay.enqueue_envelope), not the gateway, so no
gateway RPC is on the enqueue path and an in-process emit is impossible.
That is exactly the situation the change watcher already solves for the
pairing store (pairing.changed: 'written by a different process; the files
are the only shared signal') - so a new bot_relay.outbox.pending entry in
the existing watch table is the smallest correct diff: one cheap 1s-interval
stat probe folded into the existing 0.5s watcher tick, no new thread, no new
RPC, and _broadcast_global_event fans it to every connected WS client for
free. The signature is monotone (newest envelope mtime ever seen) so a
drain emptying outbox/ never re-fires the event.
Desktop (hermes-bots plugin): subscribe via the existing host.onEvent tap
(feature-detected - older shells lack it) and run drainRelayOutboxes through
a 250ms trailing debounce so a burst of signals collapses to one drain.
The 4s interval poll is intentionally UNCHANGED as the backstop: the event
tap only hears the active gateway socket, so per-connection push detection
would be complex and wrong to trade the poll against - push simply makes
the common case near-instant while older backends keep working exactly as
before.
Tests: 3 new watcher contracts (fires on enqueue, monotone across drain,
silent with no outbox) and a new relay-push-drain.test.mjs (debounce burst
-> one drain, re-arm after window, disposed no-op, poll backstop intact).
Connections ARE the peer set: every gateway connected to the Desktop
(local, remote URL, SSH, Hermes Cloud, docker) is now message_agent-
reachable. The Desktop relays over the persistent sockets it already
holds — roster sync per connection, envelope drain/deliver/reply loops —
so cross-connection DMs work exactly like local ones, replies included.
Also fixes the legacy-SOUL gate bug: profiles whose SOUL.md carries the
old plugin-appended protocol silently lost the message_agent tool
because the injection/execution gates keyed on protocol-section
non-emptiness instead of managed-install.
The eager session.resume path called _transfer_db_to_agent(agent, db)
unconditionally. With no non-launch profile selected, db resolves to the
SHARED launch handle (_get_db()), so the transfer succeeded on identity
alone — the agent IS holding that handle — and session.close() then
closed the process-wide database under every unrelated session:
subsequent writes failed with "'NoneType' object has no attribute
'execute'" and the Desktop could not open chats until restart (#91610).
This directly violated _transfer_db_to_agent's own contract ("Never
called for the shared launch handle", introduced with the ownership
lifecycle in #81071).
Gate the transfer on owns_db (dedicated handles only), and add defense
in depth: _transfer_db_to_agent now refuses db is _get_db() even when a
caller invokes it incorrectly.
Turn errors now carry a structured {layer, code, retryable} descriptor
(agent/error_surface.py) built from the same classifier the retry loop
uses. The tui_gateway stamps it on terminal error frames, retained
failed-turn snapshots, and resume replay; the Desktop error card renders
the layer title (provider / endpoint / streaming / auth / billing /
gateway / runtime / disk) plus matched actions: Retry, Switch provider,
Open logs, Copy diagnostics.
Older backends that omit the descriptor keep today's behavior (generic
title, string-sniff fallbacks) — the field is advisory on both sides.
