Follow-up hardening for the C13 log-noise cluster:
- plugins/platforms/slack/adapter.py: clarify button resolution logged
the full chosen option text at INFO (choice=%r). Choice text is user
content — log the choice INDEX at INFO and the (truncated, %.100r)
text at DEBUG only. Widens #58478's principle: no message content
above DEBUG level anywhere in the adapter.
- tests/gateway/test_slack_log_noise.py (new): behavioral suite pinning
the cluster's invariants:
* catch-all ack registered AFTER every named handler (registration
order is bolt's dispatch priority — no shadowing);
* catch-all fires for an unsubscribed event type (reaction_added),
logs only a DEBUG line naming the type, and never logs content;
* named handlers still dispatch (message → _handle_slack_message);
* end-to-end inbound message run leaves NO message text or block
content in any adapter log record (caplog at DEBUG);
* #30185's event-arrival diagnostic is metadata-only;
* clarify resolution: INFO carries index/user only, text is
DEBUG-only (fails with the adapter fix reverted — A/B verified).
Content-leak audit of all 139 logger call sites in the adapter found
two above-DEBUG leaks: the clarify choice line (fixed here) and none
else carrying message text; remaining sites log error strings, URLs
via safe_url_for_log, ids, and counts. The block-extraction DEBUG
preview was already removed by #58478 (chars= length only).
Regression test for the catch-all ack: a re.compile(r'.*') event matcher
must be registered (after every named handler, so it never shadows
message/app_mention/reaction/file routing) and must match unhandled
subscribed event types like member_joined_channel / channel_archive /
pin_added.
Salvaged from #64218 (test half only — its adapter-side catch-all is a
duplicate of #38847, which landed as the base commit of this cluster
with first-submitter credit). Fixes#6572.

Slack posts are durable workspace messages, not an ephemeral terminal
status area. Default long_running_notifications and busy_ack_detail to
off for Slack so long-running agent work does not leave permanent
operational breadcrumbs like 'Working — 9 min — iteration 12/90' in
channels. Both remain opt-in per platform via
display.platforms.slack.*.
Also covers the platform-generic shutdown-notification mute path with a
regression test (gateway_restart_notification=false must suppress both
the active-session interruption notice and the home-channel copy).
Salvaged from #69028 (quiet-defaults half only). The PR's other half —
the channel_session_scope_channels session-scoping feature — is a new
config feature outside this log-noise cluster and overlaps the session
scoping territory reworked by merged wave-1/2 Slack session work; it is
deliberately not taken here.
Without a catch-all handler, slack-bolt returns HTTP 404 for every
unhandled bot event (user_change, user_huddle_changed, reaction_added,
etc.) and never sends the Socket Mode ack. On active Slack workspaces
where the app is subscribed to high-volume events, this produces a
near-100% un-acked failure rate that crosses Slack's >95%/60-min
threshold and triggers automatic disabling of the app's Event
Subscriptions — silently killing all inbound event delivery.
Place a catch-all re.compile(r".*") handler AFTER the specific event
handlers so bolt's router matches those first. Truly unhandled events
are silently acked (200) and logged at DEBUG. The failure rate stays
near 0% regardless of which events the Slack app manifest subscribes to.
Fixes#6572
Treat Slack users.conversations missing_scope as an expected limited-scope app condition and fall back to session history without recurring warnings.
Add tests for not-ok and SlackApiError-like missing_scope responses.
Follow-up to the #68627 cherry-pick (cluster C15 — Slack platform
capability-note accuracy; earliest report/fix: #6545 by @daikeren):
1. Session/prompt stability: the pinned session-context render
(_pinned_session_context_prompt) is keyed by _ephemeral_change_key,
whose contract requires every rendered input to appear in the key.
The new _slack_tools_loaded() gate reads config + the live MCP
registration map, so its state is now hashed into the key exactly
like the existing Discord gate — a gate flip re-renders ONCE (a
legitimate bust); within a session the note stays byte-stable for
the life of the conversation (A/B: the new parity test fails with
this key change reverted, passes with it).
2. Derived, non-overpromising positive note: rather than hardcoding a
capability list that can drift stale again (the original bug class),
the tools-present note tells the agent to consult the actual loaded
Slack tool schemas for supported operations — the schemas ARE the
source of truth, so the note cannot overclaim ops a given Slack
toolset/MCP server doesn't expose (e.g. a read-only history server).
3. Tests: parity test proving a gate flip changes both render and key;
byte-stability test proving three consecutive turns in one Slack
session return the identical pinned object (sha256-equal); autouse
fixture pins the new gate so key<->render parity is env-independent.
Ports #63234 forward onto current main per teknium1's review.
gateway/session.py hard-coded the stale-API disclaimer for every Slack
session regardless of whether Slack tools were actually loaded. This
contradicted the system prompt when MCP or native slack tools were
present, causing the agent to refuse Slack API actions it could
actually perform (issue #6536).
Per review, the original predicate only checked the native 'slack'
toolset, missing Slack MCP servers (registered under mcp-<server> in
tools/mcp_tool.py) entirely. _slack_tools_loaded() now checks two
independent paths:
1. Native 'slack' toolset + SLACK_BOT_TOKEN (as before, but now calls
_get_platform_tools() with include_default_mcp_servers=True instead
of False, so a default-enabled MCP server also counts).
2. A connected MCP server that has ACTUALLY registered tools into the
live registry (new tools.mcp_tool.get_registered_mcp_server_names()),
whose name suggests Slack. This is session-scoped in the sense that
matters here: MCP servers connect once per gateway process (not
per-session), so checking the live per-server tool-registration map
is the correct availability-filtered signal -- unlike the earlier
get_all_tool_names() approach this replaces, which conflated ALL
built-in tool names process-wide, this only inspects the small,
purpose-built MCP server-name map.
Added a real regression test that registers a tool via the actual
tools.mcp_tool._track_mcp_tool_server() tracking function (not a mock
of the capability check) to verify a genuine Slack MCP server is
detected, plus a negative case for an unrelated MCP server.
5/5 Slack-specific tests pass; 126/126 in the full
tests/gateway/test_session.py file.
Follow-up to the salvaged PR #57320 commit: the PR bridged port/host/secret
for MSGRAPH_WEBHOOK but only tested webhook and api_server. Adds a test
covering the msgraph_webhook branch including extra-precedence, plus the
contributors/emails mapping for kjames2001.
WebhookAdapter and ApiServerAdapter read port/host from config.extra, but
PlatformConfig.from_dict only populates extra from the 'extra:' sub-key in
the YAML platform section. Top-level keys like port and host are silently
ignored, causing the adapter to fall back to DEFAULT_PORT (8644).
This causes silent port conflicts in multi-profile setups: a profile that
configures 'platforms.webhook.port: 8649' still binds 8644, colliding with
the default profile's webhook on the same port.
Fix: extend the shared-key bridging loop in load_gateway_config() to bridge
top-level port/host/secret into extra for WEBHOOK, MSGRAPH_WEBHOOK, and
API_SERVER platforms, following the same pattern already used for
dm_policy, allow_from, gateway_restart_notification, and other keys.
The extra dict takes precedence: if port is already under 'extra:', the
top-level value does not clobber it.
Documents user-facing wave-1+2 Slack behavior that had no docs coverage:
- decision table for require_mention / free_response_channels /
require_mention_channels / thread_require_mention / strict_mention /
ignore_other_user_mentions and how they compose
- 'Accepting messages from other bots' section with the post-#69483
semantics: allow_bots=mentions requires a CURRENT mention from
peer bots (text or Block Kit blocks); thread state never admits them
- clarify one-tap buttons (choice buttons + Other free-text mode,
in-place resolution, double-click guard, expiry message)
- slash replies are ephemeral: replace-ack, chunking, 5-post cap with
explicit truncation notice, postEphemeral fallback, never-public rule
- cron deliver targeting (slack -> home channel, slack:C... channel,
slack:U... resolved to DM) incl. standalone sender + MEDIA uploads
- send_message media + bare-user-ID DM resolution and caption behavior

Salvaged from #45765 by @navahc09 — kept the PR's callout structure
and placement, rewrote the content to match current behavior:
Slack blocks native slash commands in threads and never delivers them,
so Hermes recognises a leading '!' as an alternate command prefix.
Post-C3 command fixes the bang form also works behind a mention
(@Hermes !cmd) and with leading whitespace; unknown '!' tokens pass
through to the agent unchanged. Cross-linked the detailed
slack.md section.
0.15s missed by 1-8ms on busy CI shards twice today (runs 30025889952,
30026770278 — branches not touching this file). The assertion pins
'handler did not block on the timeout path' (blocking = seconds); 2.0s
keeps the contract per the loose-bounds flake policy.
A user who configured a provider only inside a MoA preset (advisor or
aggregator slot) has explicitly opted into that provider — the consent
gate (is_provider_explicitly_configured) now scans moa.reference_models,
moa.aggregator, and all moa.presets.* slots, so Claude Code OAuth pool
seeding and the auxiliary auto-fallback chain treat MoA-only Anthropic
users consistently with model.provider users.
Salvaged from PR #57778 (trimmed): the auxiliary_client fallback half of
the original PR was independently landed on main in ddd3a2d247 and is
dropped here; a secret-scrubber artifact in the gate test fixture is
restored to the real placeholder token.
_apply_env_overrides() force-set ``api_server.enabled = True`` whenever
API_SERVER_KEY (or API_SERVER_ENABLED) was present in the environment.
In multiplex mode, a secondary profile pins
``platforms.api_server.enabled: false`` in its config.yaml so that it
shares the default profile's API-server listener instead of binding its
own port. That profile still inherits the process-level env, including
API_SERVER_KEY, so the unconditional re-enable flipped api_server back on
and tripped the MultiplexConfigError check.
Honor an explicit disable, flagged by ``_enabled_explicit`` in the
platform's extra. Use ``extra.pop("_enabled_explicit", False)``: the
api_server branch is terminal (unlike the migrated plugin platforms, no
later registry pass re-enables api_server), so popping consumes the flag
in a single read and avoids the double-read hazard, while the final
per-platform cleanup remains a no-op.
Adds a regression test asserting that with API_SERVER_KEY set, a config
with api_server explicitly enabled:false + _enabled_explicit:true survives
_apply_env_overrides() as enabled=False (fails without the fix), while the
key is still wired through for the shared listener.

Follow-up to #60168's salvage: aggregate_moa_context() is the third
independent MoA call path; assert its aggregator call receives the
custom-provider request_overrides.extra_body via **agg_runtime.
'auto' is a sentinel meaning "inherit from main runtime / auto-detect",
not a literal model id -- already handled for cfg_model (config-derived)
in _resolve_task_provider_model, but not for the explicit `model` kwarg.
MoA reference/aggregator slots (agent/moa_loop.py's _slot_runtime) forward
a preset's `model:` field as this explicit argument rather than through
auxiliary.<task> config, so a MoA preset configured with `model: auto`
(a natural thing to try given the existing auxiliary.*.model: auto
convention) reached this function as the explicit `model` arg and took
the `model or cfg_model` branch, bypassing the cfg_model-only sentinel
check entirely -- sending the literal string "auto" to the wire as a
model id.
Normalize both the explicit `model` and `cfg_model` the same way, fixing
this at the single chokepoint every caller (MoA included) already goes
through, rather than patching moa_loop.py separately.
Extends the desktop backend's root-cause fix (aa2ae36c3f) to all remaining
console-less parent launch paths. The Windows console-flash class
(#54220/#56747) is governed by the PARENT's console: a DETACHED_PROCESS or
pythonw.exe daemon has no console, so every console-subsystem descendant
(git, gh, cmd, node, wmic, powershell) allocates its own visible conhost —
one flash per spawn, unreachable by any per-call-site CREATE_NO_WINDOW
sweep. Worse, MSDN specifies CREATE_NO_WINDOW is IGNORED when combined
with DETACHED_PROCESS, so the hide bit in the old detach bundle was dead.
Changes:
- _subprocess_compat: drop DETACHED_PROCESS from windows_detach_flags()
and windows_detach_flags_without_breakaway(); the daemon now owns a
single hidden console (CREATE_NO_WINDOW) that all descendants inherit.
- gateway_windows: _resolve_detached_python() returns the venv console
python.exe (no pythonw/base-interpreter detour — the uv-shim flash
premise only held while DETACHED_PROCESS was masking the hide bit);
UAC handoff launches console python under SW_HIDE; cmd/vbs launchers
render console python (vbs runs it window-style 0).
- gateway/run.py: restart watcher keeps sys.executable instead of
swapping in GUI-subsystem pythonw.
- web_server: dashboard actions spawn sys.executable (already carries
windows_detach_flags()).
Tests updated to pin the new invariants, including an explicit
DETACHED_PROCESS-must-stay-out regression guard.
Follow-up to the #62614 salvage: try_refresh_matching (added by the
#69843 salvage after this PR's base) calls self.current() while already
holding the now-locking non-reentrant pool lock — a guaranteed deadlock
that git merges silently (no textual conflict). Use _current_unlocked()
and cover the method in the no-deadlock test.
Follow-up to review feedback:
- Acquire self._lock in the remaining public pool-state methods:
has_credentials, reset_statuses, remove_index, resolve_target, and
add_entry. All of them read or rebind self._entries (and the mutating
ones persist auth.json), so they now hold the same lock as select()
and the query methods. None are called from within the lock, so no
unlocked helpers are needed.
- Make the blocking test deterministic: an instrumented lock records the
acquire attempt, and the test first waits for the worker to actually
reach self._lock before asserting it blocks. Previously an unlocked
method could pass if the worker thread was scheduled late.
- Extend the lock test matrix to all nine public methods; the five newly
locked ones fail the test without this fix.

`has_available()`, `peek()`, `current()` and `entries()` read (and, via
`_available_entries()`, mutate and persist) `self._entries` without holding
`self._lock`, while every other entry point — `select()`,
`mark_exhausted_and_rotate()`, `acquire_lease()`, `try_refresh_current()` —
guards the exact same access with the lock.
`_available_entries()` is not read-only: it prunes aged-out DEAD manual
entries (rebinding `self._entries` at the prune step) and calls `_persist()`
(writes auth.json). The gateway runs platform adapters in threads and cron
runs jobs in a ThreadPoolExecutor, so a status probe via `has_available()`
or `peek()` can race a concurrent `select()`/rotation: torn iteration of
`self._entries`, interleaved auth.json writes, or a lost token rotation.
Fix: take `self._lock` in all four query methods. Because the lock is
non-reentrant and `peek()` composes `current()` + `_available_entries()`,
add a lock-free `_current_unlocked()` helper and route the already-locked
internal callers (`_select_unlocked`, `mark_exhausted_and_rotate`,
`_try_refresh_current_unlocked`) through it to avoid self-deadlock.
Added regression tests: a no-deadlock check (peek re-entrancy) and a
lock-held-blocks-the-call check for each of the four methods.
Decompose children inherit the root's literal workspace_path (#37172),
so every sibling of a worktree-kind root points at the SAME checkout.
_resolve_worktree_workspace's existing-checkout shortcut then reuses
that directory on whatever branch is currently checked out, ignoring
the task's own branch_name. Net effect: sibling workers — which can be
promoted and dispatched concurrently — run in one directory on the
first sibling's branch, with no lock. Work lands on the wrong task's
branch (provenance corruption) and concurrent siblings trample each
other's index/tree.
Fix, two layers:
- decompose_triage_task: worktree-kind children no longer inherit the
root's literal path; each child materializes its own
<repo>/.worktrees/<child-id> at dispatch (dir/scratch inheritance
unchanged — children legitimately share those).
- _resolve_worktree_workspace: when the requested path is an existing
checkout of a DIFFERENT branch, fall back to a fresh
<repo>/.worktrees/<task-id> instead of silently reusing it (heals
rows that already carry a shared path). Same-branch reuse and the
no-repo/own-path degenerate cases keep the legacy behaviour.
Tests: tests/hermes_cli/test_kanban_worktree_isolation.py (5); full
test_kanban_db.py + test_kanban_decompose_db.py suites pass unchanged.

Follow-up to the #65844 salvage: the new anthropic pool test must stub
read_claude_code_credentials like the sibling tests, otherwise a dev
machine's live claude_code singleton seeds a third entry and the
no-benching assertion fails outside CI.
Two related races in credential-pool cooldown state:
1. Lost update across processes: write_credential_pool merged only
entries missing from the caller's snapshot; for entries present on
both sides the caller's in-memory copy won wholesale. A process
holding a snapshot taken before another process marked a key
exhausted would, on its next persist (e.g. a round-robin rotation),
write the key back as healthy — erasing the cooldown so every
process resumes hammering a rate-limited key. Merge status fields by
last_status_at recency: adopt the on-disk status only when it is
strictly newer AND still binding (DEAD, or EXHAUSTED with an
unexpired cooldown), and never onto re-authed (token-changed)
entries, so legitimate expiry-clears and fresh logins are preserved.
2. Wrong-key quarantine: when mark_exhausted_and_rotate received an
api_key_hint that matched no entry, it fell through to
current()/_select_unlocked() — on a freshly loaded pool that selects
the NEXT healthy key and benches it for the full cooldown TTL,
punishing an innocent credential. When a hint is provided but
unmatched, rotate without marking anything instead of guessing.
Includes regression tests.

git stash push --include-untracked exits non-zero when it saved
everything but could not DELETE some swept untracked files from the
working tree (e.g. a root-owned packaging/ directory left behind by a
sudo'd build: 'warning: failed to remove ...: Permission denied').
The updater ran the push with check=True, so this benign partial
failure raised CalledProcessError and aborted the whole update before
it even fetched — reliably, on every run, for any user with an
undeletable untracked path in the checkout.
Fix, both ends of the class:
- _stash_local_changes_if_needed: probe refs/stash before/after the
push. Non-zero push + fresh stash entry = changes are saved; warn,
reset the tracked-side leftovers (they're in the stash), and
continue the update. Non-zero push + NO stash entry = real failure;
keep aborting.
- _restore_stashed_changes: on restore, those same undeletable files
still sit in the tree, so 'git stash apply' exits 1 with 'already
exists, no checkout' even though every tracked change applied and
nothing was lost. Classify that stderr shape (strictly — any other
error line still routes to the conflict path) as restored instead
of resetting the tree and telling the user the restore failed.
Repro'd both halves with real git; behavioral E2E test covers
stash -> checkout -> restore round-trip with an undeletable dir.
A 402/429/401 is an API-key–level failure (account out of balance,
rate-limited, or key rejected), but the same key can back more than one
pool entry — e.g. an explicit pool entry plus a `model_config` entry
auto-seeded from `model.api_key`, both carrying the identical
`runtime_api_key`.
`mark_exhausted_and_rotate(api_key_hint=...)` only marked the *first*
matching entry, leaving the sibling OK. `_select_unlocked()` then kept
handing back the same depleted key, so the billing-recovery `continue`
loop in the conversation retry path never converged: the request hung
until the client disconnected (~2.5min observed against DeepSeek),
emitting only `response.created` with no 402 ever surfaced to the user.
Mark every entry sharing the failed key so the pool can reach the
"no available entries" state and let the error propagate immediately.
Adds a regression test covering two entries backed by the same key.
The dedup-reset calls assumed a full AIAgent; gateway/loop test doubles
built via object.__new__ lack _clear_context_overflow_warn and crashed
in build_turn_context (caught by test_api_content_sidecar on CI slice 3).
getattr-guard all four call sites per the established test-double pitfall
pattern (AGENTS.md #17).
Follow-up fixes for the #62625 salvage:
- Dedup-reset gap (sweeper review): when the block clears while the
context is STILL over threshold, execution enters the compression
branch — the PR's 'else' reset never ran, so the warning stayed
suppressed forever after the first block. _clear_context_overflow_warn()
now fires on every automatic compression path: turn-context preflight,
conversation_loop pre-API gate, and the post-tool loop-compaction gate.
- should_compress_info on current main: main refactored should_compress
into _automatic_compression_blocked()/_locally(); the tuple variant now
derives its reason from the same in-memory state via
_compression_block_reason(), keeping cooldown:<s>/ineffective shapes.
- ContextEngine.should_compress_info ABC default now actually returns
(should_compress(tokens), None) — the PR's default had a docstring but
no return (returned None, would crash tuple-unpacking call sites).
- Below-threshold guard: the turn-context persisted-cooldown branch and
the conversation_loop pre-API cooldown branch no longer warn when the
estimate is under threshold (should_compress_info returns a None
reason; the preflight pre-check is not a threshold guarantee). The
pre-API guard also honors compression.max_attempts instead of a
hardcoded 3, and no longer fabricates a cooldown reason.
- Noise-filter survival (#69550 composition): warning text is now a
template constant (CONTEXT_OVERFLOW_BLOCKED_WARNING_TEMPLATE) marked
FAILURE-CLASS, pinned un-swallowed in VISIBLE_COMPRESSION_MESSAGES and
in new tests that execute the real _TELEGRAM_NOISY_STATUS_RE +
_prepare_gateway_status_message.
- Contributor mapping for stanislav@local -> sl4m3.
- ContextEngine.should_compress_info() default impl so plugin engines
(e.g. _StubEngine) don't raise AttributeError at the call site.
- Centralise warning/reset in AIAgent._warn_context_overflow_blocked /
_clear_context_overflow_warn so turn-context and conversation-loop guards
share identical dedup logic and reset on the real compression boundary.
- Cover conversation_loop.py pre-API (~L1007) and loop-compaction (~L4774)
guards, not just the turn-context preflight.
- _FakeAgent mirrors the two helpers; test suite green (219 passed).
Fixes#62708
Previously, when a session crossed the compression threshold but compression
was skipped (summary-LLM cooldown, #11529, or anti-thrashing, #40803), the
model kept accumulating context until it hit the hard provider token limit and
silently stopped answering — with no signal to the user about why.
Changes:
- context_compressor.should_compress_info() returns a (should_compress, reason)
tuple. reason is 'cooldown:<seconds>' or 'ineffective' when compression is
needed but blocked. should_compress() keeps its bool contract so existing
callers (conversation_loop.py) and regression #29335 are unaffected.
- turn_context.build_turn_context() emits a deduped _emit_warning when the
context is over threshold but compression is blocked, advising /new or
/compress. Dedup keys on the block *kind* (cooldown/ineffective), not the
ticking countdown, so a cooldown doesn't re-fire the warning every turn.
- Adds tests/agent/test_turn_context_overflow_warning.py covering the tuple
shape, both block kinds, dedup, and re-fire-after-clear.
Default kanban_create children now keep fresh scratch paths, while explicit dir sharing remains supported and project context resolves to a per-task worktree. Surface resolved workspace fields in create responses/events and cover scratch mutation, nesting, explicit sharing, and project inheritance.
Fixes#67567
Dispatcher-spawned Kanban workers are finite one-shot processes, so detached delegation completions can outlive their only consumer.

Extend the existing candidate-name resolver in _supports_vision_override
to accept 'vision' as an alias for 'supports_vision' on per-model config,
for both the providers.<name>.models dict and the legacy list-style
custom_providers form.
Per review feedback on #31912: this extends the current resolver rather
than replacing its candidate-name logic. Named custom providers resolve
to the runtime value provider='custom' while the config keeps the
user-declared name under model.provider; that lookup path is preserved.
Adds regression tests covering model.provider=my-vllm with runtime
provider='custom' for both config shapes.
The bare truthiness test on _compression_skipped_due_to_lock is fooled
by MagicMock auto-attributes on test-double agents (skill pitfall:
MagicMock defeats hasattr/truthiness duck-typing) — the type-ahead CLI
test's MagicMock agent took the lock-skip branch and skipped the
transcript commit. Real values are None/True/holder-string; pin the
check to 'is True or isinstance(str)' at all three consumer sites.
Follow-up to the salvaged #57634 commits:
- agent/manual_compression_feedback.py: new describe_compression_lock_skip()
— single source of truth for lock-skip wording. A descriptive holder
string means another compressor CONFIRMED holds the lock ('already in
progress (holder: ...)'); True/None means acquisition failed without a
confirmed holder (hermes_state.try_acquire_compression_lock catches
sqlite3.Error internally and returns False), so the message says
'could not acquire ... the lock check failed' instead of falsely
claiming a concurrent compression is running.
- cli.py, gateway/slash_commands.py, tui_gateway/server.py (all three
in-process consumers: session.compress RPC, command.dispatch compress
branch, slash.exec mirror) now route through the shared helper.
- tui_gateway/server.py command.dispatch compress branch: catch
CompressionLockHeld explicitly — it previously fell into the generic
'compress failed' error handler.
- Deferred-notify contract (#69324): lock-skip discards the pending
context-engine notification (committed=False) in _compress_session_history
and the CLI path before returning.
- tests: lock-skip wording pins per surface, VISIBLE_COMPRESSION_MESSAGES
noise-filter carve-outs for both wordings, MagicMock signal opt-outs for
sibling tests added on main after the original PR.
