The pane, in-app browser, and reaction tools were gated on HERMES_DESKTOP=1 —
an env var set only on backends Electron spawns itself (local and SSH). A
desktop client connected to a plain URL gateway or Hermes Cloud lost all six:
they were stripped from the schema before the model saw them, on the same
backend whose platform hint was telling it "you are chatting inside the Hermes
desktop app". open_preview, read_preview, read_terminal, close_terminal,
focus_pane, and react_to_message were all silently absent.
The client is not the host. Capability now resolves from the session's own
source, which session.create already carries:
- The six tools move into a `desktop_ui` toolset, off _HERMES_CORE_TOOLS so no
other platform pays their schema.
- _gui_surface_toolsets(platform) folds `desktop_ui` (and the existing
`project` tools) into the GUI gateway's resolution when the session's
platform is the desktop app — the same answer on every topology.
- check_fn drops the env probe. It kept the one thing that is genuinely a
per-process/user fact: react_to_message's display.message_reactions opt-in,
which the desktop mirrors onto whichever gateway it is connected to.
react_to_message was doubly broken: it read that toggle behind the env gate, so
even a local-backend user's Settings toggle could not reach a remote session.
The embedded terminal pane keeps working correctly the other way round: it runs
`hermes --tui` against a desktop-spawned backend, and a tui-sourced session
gets no GUI tools even though HERMES_DESKTOP=1 is set on that process.
The turn finalizer already hands back steer text that queued after the
final tool batch — result["pending_steer"], with the comment "hand it
back to the caller so it can be delivered as the next user turn instead
of being silently lost." Every interactive surface honors that contract
(cli.py, gateway/run.py, tui_gateway/server.py all requeue it). The
delegation layer doesn't: _run_single_child never reads it, so a steer
queued into a delegated child that finishes first vanishes with no trace
in the completion entry. There is also no sanctioned sender: the registry
has interrupt_subagent() but no redirection-side mirror, and session.steer
cannot reach children (lazy watch sessions have agent=None, so it 4010s).
Complete the contract for delegated children — both halves:
- steer_subagent(subagent_id, text): redirection-side mirror of
interrupt_subagent(). Resolves the live child in _active_subagents and
queues text via AIAgent.steer(). True means queued, not delivered.
- missed_steer retention: when the child's result carries pending_steer,
_run_single_child names it on the completion entry (missed_steer field
plus a summary note) so the parent can re-issue the guidance instead of
trusting it landed. This is what makes adding a sender safe: without it
the finish-before-drain race silently loses the text — the exact loss
the finalizer contract exists to prevent.
- subagent.steer gateway RPC beside subagent.interrupt so programmatic
hosts (dashboard, voice layers, ACP bridges) get an in-tree caller;
catalogued in programmatic-integration.md.
- docs: "Steering a Running Subagent" section in delegation.md covering
the queued-vs-delivered semantics.
Tests: registry-level steer coverage (delivery, unknown id, empty text,
dead record, raising agent), the finish-before-drain race retaining
missed_steer, and the RPC contract (4000/4002 validation, queued and
rejected envelopes).
* feat(agent): read_preview — the desktop-gated tool that reads the in-app browser
The agent could open the preview pane (open_preview) and read the embedded
terminal (read_terminal), but the browser it had just opened was a black box —
'what does this page say?' had no answer. read_preview mirrors read_terminal
end to end: HERMES_DESKTOP-gated via check_fn (zero schema footprint outside
the GUI), dispatched through the same agent callback pattern, windowed with
start/count so a long page pages instead of flooding context.
* feat(gateway): preview.read blocking bridge
Same lifecycle as terminal.read: the tool blocks on preview.read.request, the
renderer answers preview.read.respond (allow_expired — a slow page extraction
losing the 45s race must not surface a raw 4009), and a timeout emits
preview.read.expire so late answers resolve quietly.
* feat(desktop): the renderer serializes the active preview tab for the agent
preview-reader.ts is the preview analog of the terminal's buffer registry: the
URL pane registers a page reader (webview executeJavaScript → title + visible
innerText) keyed by tab id; readActivePreview resolves the ACTIVE tab, windows
the text (24k cap per read), and answers file/artifact tabs with identity plus
a note pointing at the tool that reads that content directly. The gateway
event handler answers preview.read.request beside terminal.read.request.
Sending one 80 ms frame per RPC is ~12.5 gateway calls/s for as long as the
ear is armed. Drain up to 4 queued frames into a single wake.feed payload
(backend feed() already splits long buffers into engine frames) — ~3 RPCs/s
steady-state. Fix the wake.feed size-cap comment (64000 bytes = 2 s, not
0.5 s).
- wake.status reports effective capture from the armed detector (client vs
local), plus frame_length/sample_rate; GUI status probes prefer client
- Gateway test doubles accept external_audio on start_listening
- Desktop PCM feeder uses a bounded ordered queue instead of dropping frames
while a wake.feed RPC is in flight
- /wake on and status/re-arm paths pass client_capture so remote reattach works
Remote headless backends have no PortAudio mic, so "hey hermes" fails even
when openWakeWord is installed. Let the desktop stream 16 kHz int16 PCM via
wake.feed while detection stays server-side.
- wake_word.capture: auto|local|client (+ GUI client_capture prefer)
- WakeWordDetector external_audio queue + feed_audio API
- wake.feed RPC; wake.start/status report capture + frame_length
- Desktop getUserMedia feeder; stop on wake.detected, re-arm after voice
- Docs + unit tests (26 pass in tests/tools/test_wake_word.py)
A session created in the wrong directory needs its cwd corrected after the
fact. session.cwd.set only reaches live runtime sessions, so cold rows were
stuck. The new RPC targets the persisted row by session_key, validates the
folder, and REPLACES the git branch/root identity (update_session_cwd grows a
replace_git_meta flag) so the project tree's grouping follows the move instead
of pinning the session under the project it left via a stale git_repo_root.
A live idle agent bound to the row is re-anchored through the runtime path;
a mid-turn session refuses with 'session busy'. Runs on the RPC pool — the
git probes are subprocesses.
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.
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.
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).
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.
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).
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.
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
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').
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.
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.
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.
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.

Unify @null-runner's selector approach with the merged #77019 keepalive:
the reapers now match live delegations by origin UI sid AND (when the TUI
owns the durable lifecycle, never for gateway-viewer tabs, #60609) by the
durable session_key, so a delegation dispatched from an earlier tab of
the same resumed session still keeps it alive. has_live_for_session also
counts 'stalling' to match the #77019 live-state set. Explicit teardown
(_finalize_session) interrupt semantics unchanged.
Replace the process-global HERMES_CRON_SESSION env var with a per-session
ContextVar so a cron tick in the gateway process cannot leak into unrelated
live gateway/API/TUI turns. The cron scheduler now sets the ContextVar
inside the job's try/finally scope and resets it on cleanup. Gateway, API
server, ACP adapter, and TUI gateway all pass cron_session='' to explicitly
mark their sessions as non-cron, masking any stale process env.

Closes#37968
Simplify-pass follow-up on the #66355 salvage:
1. _config_settings runs on EVERY trim attempt (before the cooldown
check) and only reads — swap load_config for load_config_readonly.
Deep-copying the whole config per attempt generates exactly the
allocator garbage this module exists to release. Tests re-seamed.
2. Trim-failure logs demoted warning->debug at all 3 periodic sites
(gateway housekeeping, idle reaper, slash worker): sibling failure
branches in the same loops log at debug, and a persistent failure
(e.g. broken import after a partial update) would otherwise warn
every 60s forever.
3. The frame-inspection test now asserts the expected locals exist
before reading them — a rename in _run_prompt_submit fails the test
loudly instead of vacuously passing on None.
Add config-driven glibc malloc_trim for long-lived Hermes processes:
- hermes_cli/mem_trim.py: trim_memory() with configurable cooldown,
RSS snapshot telemetry, and forced-trim INFO logging
- gateway/run.py: periodic trim in gateway housekeeping loop
- tui_gateway/server.py: trim in idle reaper (~every 5 min)
- tui_gateway/slash_worker.py: trim on turn boundary
- run_agent.py: force trim on agent close
- hermes_cli/config.py: context.memory_trim config section
(enabled, cooldown_seconds, log_every_n, info_log_min_delta_mb)
CSA tier-4 reviewed (4 rounds, 0 HIGH/MEDIUM/CRITICAL remaining).
Supersedes PR #63708 + #64591 with enhanced telemetry and gateway/slash_worker coverage.
NOTION_API_KEY/LINEAR_API_KEY defaults, DEEPINFRA_API_KEY model gate, FAL_KEY via the file's own _scoped_credential helper, XAI/VERCEL/DAYTONA presence checks, GITHUB_TOKEN/GH_TOKEN + GitHub App creds in tirith/skills_hub, and the masked HERMES_API_KEY display in tui_gateway config.show all route through get_secret.
alongside every set_hermes_home_override() call site on the tui_gateway
path, and converted session.create, session.resume (both the _make_agent
and _init_session scopes), the lazy _build resume and the per-turn submit
handler. session.branch was missed.
The branch handler already binds the parent's HERMES_HOME and its
profile-scoped state.db — its own comment says it mirrors
session.create/resume — but builds the branched agent with no secret scope.
get_secret() then falls through to process os.environ, which in an
app-global/remote backend is the LAUNCH profile's environment: a session
branched off profile X authenticates with profile Y's credentials. That is
the same cross-profile resolution #67605 fixed for the sibling paths, and it
is silent (multiplexing is only activated by the messaging gateway, so the
fail-closed UnscopedSecretError path never fires here).
Install set_secret_scope(build_profile_secret_scope(parent_home)) for the
build and release it in the same finally block as the home override.
Salvage-note: code relocated from tui_gateway/server.py to tui_gateway/methods_session.py (session handlers moved after the PR was opened); test patch targets unchanged — HandlerRegistry rebinds handlers onto server.py globals
Makes interrupt-protected context compression cancellable by an explicit
user or lifecycle stop, without weakening protection against ordinary
incoming messages, voice interjections, or active-turn redirects.
Separates explicit hard cancellation from ordinary interrupt/redirect
state with a dedicated threading.Event; introduces
AuxiliaryExplicitCancellation as an attempt-local frozen-cause signal;
isolates the synchronous provider callback in a bounded daemon worker
during protected compression; atomically linearizes Codex timeout
cleanup against explicit cancellation; propagates hard cancellation
through child agents and explicit stop surfaces; serializes hard-cancel
admission against compression commit admission with
CompressionCommitFence; aborts before session rotation or late DB commit,
restores in-place transcript mutations and compressor state, and releases
the heartbeat and compression lease.
Based on #74449 by @suparious. Resolved merge conflicts in
agent/context_compressor.py (feasibility check + try/except) and
tui_gateway/methods_session.py.
Desktop edit / regenerate / restore-checkpoint send truncate_before_user_ordinal
on prompt.submit. The handler rewrote session['history'] first, then called
replace_messages, and on failure only printed to stderr and still started the
turn. When the durable write fails, in-memory history is already truncated
and history_version is bumped while state.db still holds the pre-edit tail.
The agent flush is append-only for history-dict identities, so the new
exchange is appended on top of the 'undone' turns — durable zombie history.
Fix: persist first; only then mutate memory. On failure return 5008 and
leave memory/DB unchanged.
Based on #72876 by @necoweb3. Adapted: the handler moved from
tui_gateway/server.py to tui_gateway/methods_prompt.py since the PR's base.
Builds on #72787's current_root guard (cherry-picked with authorship
preserved). Two further hardenings for #72776:
- require the settled cwd and the workspace to share the same common .git
dir (the shape 'git worktree add' produces), so a git workspace visiting
an UNRELATED repo is a browsing visit, not a re-home (repro'd by
Johnny-xuan in the issue thread);
- never reconcile over an explicitly chosen workspace (explicit_cwd),
while a settle-adopted cwd stays followable via a cwd_from_settle
marker cleared by _set_session_cwd / project switch.
Fixes#72776
`_reconcile_session_cwd_from_terminal()` treats a settled terminal cwd in a
different git working tree than the session's workspace as a relocation. But
when the session's workspace is not itself in a git repo, `_git_repo_root_for_cwd(current)`
is None, so the `landed == _git_repo_root_for_cwd(current)` guard never matches
and the FIRST git directory a tool call steps into hijacks the session: its
cwd/git_repo_root flip to that repo, later tools run from the wrong place, and
the repo's AGENTS.md gets injected into an unrelated conversation.
Only reconcile when both the current and settled cwds resolve to valid, differing
git roots. A non-git workspace visiting a git repo to read a file or run a command
is a browsing visit, not a re-home — matching the docstring's own intent that
`cd`-ing away must not re-home the chat. The intended "follow into a worktree"
behavior is unaffected: that path starts from a git checkout, so current_root is
valid there.
Adds a regression test covering a non-git workspace that touches a git repo.
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.

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.
The salvaged commit renamed server.py's private _INDICATOR_STYLES/_INDICATOR_DEFAULT
to the shared hermes_constants imports, but methods_config.py (extracted after the
original PR was authored) still referenced the old private names through the
server-globals rebinding. Import the shared constants directly.
The /indicator command was registered in COMMAND_REGISTRY, listed in
/help, offered by tab-completion, recommended by the tips system, and
even documented in config.py — but it had no actual handler. Running
/indicator in the CLI produced "Unknown command: indicator".
Add _handle_indicator_command to CLICommandsMixin that:
- Shows the current indicator style when called with no args or "status"
- Validates the requested style against the shared INDICATOR_STYLES
allowlist (ascii | emoji | kaomoji | unicode)
- Persists the choice to display.tui_status_indicator in config.yaml
via the existing save_config_value helper
- Falls back to session-only when config save fails
The indicator-style allowlist is defined once in hermes_constants as
INDICATOR_STYLES + DEFAULT_INDICATOR_STYLE and imported by all three
consumers (CLI handler, command registry, TUI gateway config handler),
preventing drift between the TUI and CLI validation.
Also adds tests/cli/test_indicator_command.py covering dispatch,
validation, persistence, and registry integration.

Disk-full / ENOSPC / SQLITE_FULL on first-message session persist used to be
swallowed as a debug log while prompt.submit still returned streaming, so the
send vanished with no error. Re-raise those failures, return a real RPC error,
and stamp session_persistence_failed turns with error so clients get a terminal
error frame.
The idle-TTL reaper, the LRU cap, and the WS-orphan reap tear down a
live session without the client asking. Nothing was pushed, so a client
kept a runtime id the backend had already forgotten and only found out
by failing a later prompt. Broadcast session.reclaimed with the runtime
id and the reason; client-initiated closes stay silent.
* fix(vision): mount images/ upload dir into sandboxes and permit host read (#69575)
Desktop, clipboard, and PDF uploads land in the flat top-level
HERMES_HOME/images/ dir, but Docker sandboxes only mounted the cache/
subtree and the vision resolver only permitted host reads from the media
caches. So vision_analyze on any desktop-app upload failed under a Docker
backend with "not reachable inside the sandbox".
- Add ("images", "images") to _CACHE_DIRS so the uploads dir is bind-mounted
into sandbox containers through the existing profile-scoped cache-mount and
reverse-mapping mechanism.
- Add home/"images" to _media_cache_roots() so the non-local host-read
allowlist permits reading uploads directly from the host filesystem.
- Cover the mount entry, the container path mapping, and the Docker-mode
resolver read for a profile-scoped upload.

* fix(tui_gateway): write image uploads under the session's profile home (#69575)
The attach RPCs (image.attach_bytes, clipboard.paste, pdf.attach) wrote
uploads to the gateway's module-cached launch home via _hermes_home/"images".
Those RPCs run before prompt.submit installs the session's profile HERMES_HOME
override, so in a multi-profile / root-gateway deployment the file landed in
the launch home while the sandbox mount and the vision host-read allowlist
both resolve the session profile's images/ at run time — the agent could
never see the upload it was handed.
Add _session_images_dir(session), which anchors the write on the session's
stored profile_home when present (matching the mount/read scope) and falls
back to the launch home otherwise. Route both write sites through it, keeping
per-profile isolation.

A model picked mid-turn is applied at the next turn start, but the end-of-turn
session.info (_emit_settled_session_info) reads the still-live agent — the OLD
model — and clobbered the optimistic paint, so the UI showed the new model, then
snapped back to the old one when the turn ended, then switched for real on the
next turn. Report the queued pick's model/provider in _session_info while a
switch is pending (it IS the model the next turn runs), so the display stays on
the user's choice through the settle. Cleared once the switch applies.
* feat(tui): Ctrl+O opens the model picker without clearing your draft
Reaching the model picker meant typing /model, which forces you to wipe
whatever you'd already drafted. Bind Ctrl+O to open the same picker overlay
directly, leaving the composer untouched. Ctrl+O is added to the textInput
pass-through allowlist so the composer doesn't swallow it, mirroring the
existing Ctrl+X session-switcher path.
* feat(tui): apply a mid-turn model switch at the next turn instead of rejecting it
Picking a model while a turn was streaming hit a 4009 'session busy' reject:
switch_model() mutates the agent's model/provider/base_url/client in place and
the worker thread reads those every iteration. Now config.set queues the pick
in session[pending_model_switch] and _apply_pending_model_switch applies it on
the turn thread at the next turn start, before any model call — no race, no
interrupt, no waiting on the client rebuild. The TUI paints the pick optimistically
and notes '(applies next turn)'.
Slice 1 fell over on eight DB fakes with frozen get_messages_as_conversation
signatures — the new opt-in kwarg is part of the method's contract now, so
the fakes accept **_kwargs like the real SessionDB. Also opts the child-watch
resume projection into row ids: it feeds the same _history_to_messages as the
desktop resume, so reactions on a watched child session address rows the same
way.
One lever, every surface. The renderer toggle persists locally and mirrors
into display.message_reactions; the backend gates the agent's
react_to_message tool (check_fn) and the model-context annotation on the same
key, and the ':' composer trigger reads the store at detection time. Off
means off everywhere: no ☺ slot, no right-click picker, no :shortcode:
popover, no agent reactions, and the model hears nothing — while reactions
already persisted keep rendering so history doesn't lose data. Also fixes the
import-order lint error CI flagged in composer/index.tsx.
CI caught ACP session restore seeing an unexpected _row_id in restored
history — get_messages_as_conversation feeds more than the desktop, and
changing the default shape broke the strictest consumer. Row ids are now
include_row_ids=True, requested only by the gateway's resume/display
projections; ACP restore, export, and inspection get the transcript in its
historical shape.
