Two tests on main pinned the pre-#20583 bare-ts marker mechanism
(_mentioned_threads entries and _slash_command_contexts key shape).
The salvaged workspace scoping intentionally changes both:
- _mentioned_threads now records (team_id, ts) markers when the event
carries a team id, so the top-level-mention test asserts the scoped
tuple.
- _slash_command_contexts keys are (team_id, channel, user) 3-tuples
when the slash payload includes team_id.
Follow-up to the #20583 cherry-pick (jordanhubbard).
origin_session_id (the api_server wake self-post target) lived only in
the in-memory record: durable dispatch persistence and abandoned-
delegation recovery omitted it, leaving completions recovered after a
process restart unroutable to api_server sessions. Persist it in the
async_delegations table (CREATE TABLE + ALTER TABLE migration for legacy
DBs), restore it on recovery, and expose it via get_durable_delegation.
Also adds the contributors mapping for ianks (PR #64998 author).
Follow-up to #64998 (sweeper review F3).
/v1/runs bound only session_key at its _bind_api_server_session call, so
tools.async_delegation._current_origin_session_id() — which reads the
request-scoped HERMES_SESSION_CHAT_ID — returned "" on that route and
runs-originated background delegations stayed forced-sync with no wake
target. Bind chat_id/session_id the same way the other agent-entry routes
do via _run_agent(). Follow-up to #64998 (sweeper review F2).
On non-push adapters (api_server) the wake self-post IS the delivery, but
the cursor advanced before the self-post ran and a failed/exhausted post
was swallowed by the best-effort except — permanently losing the event.
Reorder the else-branch: for non-push adapters run the self-post FIRST and
only advance the cursor once it succeeds. A failure rewinds the pre-send
claim (same guarantee as the existing SendResult(success=False) path) so
the next tick retries, with the same MAX_SEND_FAILURES drop threshold.
Push-capable adapters keep the pre-existing advance-then-best-effort-wake
behavior. Follow-up to #64998 (sweeper review F1).
Wake-ups for kanban notifications and background delegation completions were
injected via handle_message() using a build_session_key()-derived key, which
can never match the raw X-Hermes-Session-Id key that api_server sessions run
under — so the wake landed in a session nobody was reading. On top of that,
ApiServerAdapter.send() reports failure without raising, and that was treated
as a successful delivery, so the notify cursor advanced past events that were
permanently lost; and background delegation was forced synchronous on
api_server since there was no way to wake the session afterward.
Fix: route wake-ups for non-push adapters through a self-post to
/v1/chat/completions with the original session id, treat non-raising send
failures as failures (rewind instead of advancing the cursor), and re-enable
background delegation whenever a session id is available to wake.
The origin session id is captured from the request-scoped api_server chat_id
binding rather than HERMES_SESSION_ID: constructing a child agent calls
set_current_session_id() with the subagent's internal id, clobbering that
variable right before dispatch would read it and misrouting the wake into
the subagent's own session.

Correction to the previous commit (PR #68402): the claim that api_server
never intercepts MEDIA: tags is inaccurate on current main.
_resolve_media_to_data_urls() (gateway/platforms/api_server.py) DOES
inline image MEDIA: tags (<=5MB, image extensions only) as base64 data
URLs on the four main endpoints (_handle_session_chat,
_handle_session_chat_stream, _handle_chat_completions, _handle_responses).
The real gaps elphamale's PR points at are narrower:
- the /v1/runs output path (_handle_runs) never calls the resolver;
- non-image filetypes are never resolved anywhere (_MEDIA_IMG_EXT is
image-only).
Reword the hint to teach both halves: images via MEDIA: work on the
chat/completions/responses endpoints; non-image files and anything on
the runs endpoint must fall back to plain file paths in the response
text. Update the test to pin the scoped guidance instead of a blanket
prohibition.
Every PLATFORM_HINTS entry for a messaging platform (Telegram, WhatsApp,
Discord, Slack, Signal, WebUI, desktop) teaches the model the MEDIA:/path
convention because an interception mechanism actually resolves it there
(native attachment delivery, or a validated/inlined data URL). The cli
entry, which has no such mechanism, explicitly tells the model NOT to use
it and to state the path in plain text instead.
The api_server entry had neither instruction. Its /v1/runs handler never
routes the final response through any MEDIA: resolver (confirmed against
source: none of the four call sites of the api_server module's media-tag
resolver are inside its runs-endpoint handler), so a MEDIA:/path tag there
renders as inert literal text in the API response — exposing a raw host
filesystem path to the caller with no delivery ever taking place. Nothing
platform-specific told the model not to use a convention it's correctly
taught for several sibling platforms in this same dict, so the general
cross-platform habit could surface here too, unlike cli where an explicit
prohibition already closes the gap.
Mirrors cli's prohibition, adapted for api_server's actual constraint: no
"state the path in plain text" fallback, since a typical API caller has no
filesystem access to the host at all. Points at "a registered file-delivery
tool" generically rather than naming any specific tool, since api_server
toolsets are deployment-defined.
The api_server adapter returned error code "invalid_api_key" for
API_SERVER_KEY authentication failures, which the Desktop error
classifier misidentified as a provider (OpenRouter/OpenAI) key
problem — showing "OpenRouter API key missing" when the real issue
was gateway auth.
Changes:
- gateway/platforms/api_server.py: return "gateway_auth_failed" code
with descriptive message for API_SERVER_KEY auth failures
- apps/desktop/src/store/notifications.ts: add "gateway_auth_failed"
handler before "invalid_api_key" to show correct error message
- agent/error_classifier.py: add "gateway_auth_failed" to auth patterns
- tests: update test_session_api.py to expect new error code
Fixes#39365
When _api_key_passes_startup_guard() rejects the key (missing,
placeholder/too short, or fail-closed unverifiable strength), connect()
returned a bare False with no fatal-error info. gateway.run's reconnect
watcher treats that as transient and re-queues with backoff forever —
each retry re-instantiating the adapter and its ResponseStore sqlite
connection. Observed in production (#37011): ~501 leaked connections
(1002 fds) over ~2.5 days until EMFILE made the whole gateway
unresponsive.
Set a non-retryable fatal error (api_server_key_invalid) in connect()
when the guard rejects, covering all three rejection branches, so the
platform drops from the reconnect queue; recover with
`/platform resume api_server` after fixing the key. Same treatment as
the port-conflict guard (api_server_port_in_use, #65665 / bda8bd76a8).
Tests mirror the port-conflict precedent: each rejection path asserts
connect() is False, has_fatal_error True, fatal_error_retryable False,
and fatal_error_code api_server_key_invalid, plus a strong-key control.
Re-implementation of #38803 by @cifangyiquan against current main —
their patch targeted the old inline guard in connect() which was since
extracted to _api_key_passes_startup_guard() (and gained the
fail-closed branch in 683059feb5), so the original diff no longer
applies. Their production diagnosis and non-retryable direction
preserved.
Refs: #38803, #37011
Salvaged from PR #36180 (commits 68dfeb4b16 and 86f437509b by arimu1),
re-applied onto current main with the incidental black-reformat churn
stripped out (~1,700 lines -> the semantic change + tests).
Previously gateway/config.py enrolled the api_server platform on
`api_server_enabled or api_server_key`, so API_SERVER_ENABLED=true with
no key (or a weak/placeholder key) still loaded the platform: the
adapter is instantiated (ResponseStore/SQLite opened in __init__), the
reconnect watcher spins, and the startup guard refuses at connect() —
logging errors forever. Now the platform is enrolled only when
API_SERVER_KEY passes the same strength bar as the adapter's startup
guard (has_usable_secret, min_length=16), via a shared
_has_usable_api_server_key() helper.
The no-op `lambda cfg: True` connected-checker for API_SERVER is also
replaced with the same key check, so get_connected_platforms() only
reports the platform "up" when it could actually start.
Known limitation (intentionally out of scope): a YAML config with
`platforms.api_server.enabled: true` and no key still loads the
platform; this gate covers the env-override path only.
Dropped from the original PR: EMAIL/SMS checker additions (scope creep
beyond the PR title; absent on current main) and the wholesale black
reformat of gateway/config.py and tests.

Also fixes the TestFormatMessageTableIntegration fixture to match
PlatformConfig's current signature (no 'name' kwarg).
Widen #48476's fence guarantees to the two splitters that still emitted
fence-broken chunks:
* GatewayStreamConsumer._split_text_chunks (fallback final send): close
the orphaned ``` at each chunk boundary and reopen it — with the
original language tag — on the next chunk, mirroring
BasePlatformAdapter.truncate_message's contract. Headroom is reserved
so balanced chunks stay within the platform limit.
* Slack block_kit._split_text (3000-char section chunking): same
close/reopen balancing for mrkdwn section text carrying fences.
With these, every chunk boundary — non-streaming send
(truncate_message), streaming overflow (_truncate_for_stream via
adapter.truncate_message per #45938), fallback final
(_split_text_chunks), final-send balance (ensure_closed_code_fences),
and Block Kit section splits — delivers fence-balanced chunks.
Regression tests probe each path with fenced fixtures, assert per-chunk
balance, limit compliance, language-tag reopening, and prose passthrough.
Slack's Block Kit `markdown` block accepts standard markdown (tables,
headers, task lists, fenced code with syntax highlighting, links) and
lets Slack translate it natively — eliminating the lossy markdown→mrkdwn
conversion for the rendered layout. Enable via
platforms.slack.extra.markdown_blocks.
Safety rails added on top of the original design:
* opt-in (default off) — Slack documents the block for 'apps that use
platform AI features' and does not guarantee availability across all
app types / surfaces, so unconditional adoption is not safe yet
* the mrkdwn-converted text field is ALWAYS kept as the
notification/search/accessibility fallback
* content over Slack's 12k cumulative markdown-block cap declines to the
rich_blocks renderer / plain text path
* the existing block-rejection retry (invalid_blocks / msg_too_long /
too_many_blocks) re-sends the plain mrkdwn payload, so an unsupported
surface degrades gracefully instead of dropping the message
* when both modes are enabled, markdown_blocks is preferred over the
local rich_blocks renderer; rich_blocks remains the fallback
Adapted from #8554 by @shivasymbl — the original patched the deleted
gateway/platforms/slack.py and switched unconditionally; reimplemented
against the plugin adapter's _maybe_blocks/sanitize_blocks pipeline.
Fixes#8552.
Slack mrkdwn has no table syntax — GFM pipe tables render as literal-pipe
noise with a raw |---|---| separator row. Wrap detected tables in ```
fences so they render as monospace preformatted text, and pad cells to
per-column max display width (East-Asian Wide / Full-width chars counted
as 2 columns) so columns stay aligned even with CJK content.
Tables already inside fenced code blocks are left untouched, and the
emitted fences carry no language tag so they compose with the
lang-tag-strip pass. This covers the plain-mrkdwn text path; the opt-in
rich_blocks path already renders native Block Kit table blocks.
Reapplied from #16648 by @kylezh — the original patched
gateway/platforms/slack.py, which was migrated to
plugins/platforms/slack/adapter.py in the plugin migration.
Fixes the non-rich_blocks table path described in #8552.
ensure_closed_code_fences previously only handled triple-backtick
(```) code-block fences. Single backtick (`) inline-code spans have
the same problem: an orphaned opening backtick causes the remainder
of the message to render as inline code on Discord and other platforms.
After balancing triple-backtick fences, strip complete ```...```
regions and count remaining standalone backtick markers. If odd,
append a closing backtick. Same trade-off as the triple-backtick fix:
a stray closing backtick may create a brief empty inline-code span,
which is far less harmful than the rest of the message being inline code.
B1: When reasoning content contains ``` e.g. model quoting code in
its thinking, wrapping it in an outer ``` for display causes the
inner fence to break the outer block.
Adds escape_code_fences_for_display() in gateway/stream_consumer.py,
called from gateway/run.py before wrapping reasoning in the outer
``` display block.
Slack's mrkdwn does not strip the optional language tag from fenced
code blocks like GitHub-flavored markdown does — it renders
```text\nfoo\n``` as a code block whose literal first line is "text".
The agent emitted ```text fences around raw command output, which
surfaced "text" as the first line of every such block.
Drop the tag from the opening fence in format_message() before stashing
the block behind a placeholder. Stripping only fires for a genuine
opening fence — a ``` at the start of a line, tagged with a single
token (no spaces or backticks) — and the original line ending is
preserved. The fence-protection regex deliberately matches loosely, so
a mid-line ``` (e.g. an inline ```span``` wrapping across a newline)
can be grouped as an "opening fence" whose first line is real content;
differential fuzzing against the pre-change formatter (40k generated
messages) confirms the only behavioral delta is the tag strip itself.
The Block Kit renderer is unaffected: render_blocks() intercepts fences
itself before mrkdwn_fn is applied, so this only changes the mrkdwn
surfaces that still go through format_message() — the plain-text
fallback field (notifications, search indexing, accessibility),
slash-command ephemeral replies, and standalone cron delivery.
Originally written against gateway/platforms/slack.py; ported to
plugins/platforms/slack/adapter.py after the adapter migration in
5600105478.
Manually verified against a live Slack workspace (pre-migration
adapter; the ```text case strips identically) — code blocks no longer
carry a literal "text" first line.
format_message unescapes already-escaped input before re-escaping, so that
pre-escaped text doesn't get double-escaped. That unescape was three
sequential str.replace calls, which re-scan each other's output:
"&lt;" --(& -> &)--> "<" --(< -> <)--> "<"
The & produced by the first replace pairs with the following "lt;" and
decodes a second time. "&lt;" is the wire form of the literal text
"<", so the text is silently destroyed: Slack receives "<" and renders
"<". Anyone writing about HTML or markup ("&lt;b&gt;" -> "<b>")
loses their literal text, with no error.
re.sub scans left-to-right and never re-scans its own replacements, so a
single pass fixes it. The escape pass on the next line is left untouched --
it is correctly ordered (& first, so the &s it inserts aren't re-escaped).
Only the double-decode cases change; every other input is byte-identical
before and after. This is the same round-trip invariant the neighbouring
test_pre_escaped_{ampersand,lt,gt}_not_double_escaped tests already assert,
extended to the case they miss. Affects the plain mrkdwn path (send,
edit_message) and Block Kit sections, which route section text through
format_message.
Build the full reaction pipeline on top of the #29916 base:
- Opt-in gate: slack.reaction_triggers (default OFF — reaction events
stay acked-and-dropped so busy channels don't wake the agent on every
emoji). 'true' routes reactions on the bot's OWN messages; an explicit
emoji-name list routes those emojis from any message (handoff flows).
- reaction_removed events now route too, distinguished by the
cross-platform text convention reaction:added:<emoji> /
reaction:removed:<emoji> (matches the Feishu and Photon adapters, so
agents and skills see one shape everywhere).
- Authorization: the reactor becomes the synthesized message's user, so
the early _is_user_authorized gate and allowed_channels whitelist
apply exactly as for typed messages. _hermes_force_process only skips
the mention requirement (a reaction on the bot's own message is
definitionally addressed to the bot), mirroring Feishu/Photon.
- Gateway hooks (#33111 by @johnkattenhorn): every human reaction on a
message item fires reaction:added / reaction:removed through the new
BasePlatformAdapter.set_reaction_handler → GatewayRunner
._handle_reaction_event → HookRegistry.emit, independent of the
routing opt-in. Documented in hooks.md.
- Channel handoff (#45265 by @Kev-fs): slack.reaction_trigger_target
routes the reaction turn to a configured channel (top-level via
_hermes_no_thread_response + reply-anchor suppression in
gateway/platforms/base.py) or C123:<ts> thread.
- Manifest: reaction_removed event subscription added alongside
reaction_added/reactions:read.
- Docs: slack.md Reaction Triggers section; hooks.md event table rows.

handling — same plumbing class, superseded by this consolidated shape).

Slack reaction_added events were explicitly acked and dropped, so a user
reacting to a bot message (👍 to approve, ✅ to acknowledge) produced
nothing. Forward them through the normal message pipeline as synthesized
MessageEvents whose text is the reaction emoji (translated to unicode
for common names), keeping the downstream auth gate, thread-context
fetch, dedup, and skill routing unchanged.
- Self-reactions and non-message items are dropped; reactions on
messages not sent by this bot are dropped (Feishu-adapter parity).
- The reacted-to message's thread parent becomes the synthesized
thread_ts so the reaction lands in the same session as a reply would.
- Manifest gains reactions:read scope + reaction_added bot event.

Salvaged from PR #36220, ported onto the current SessionStore (SQLite-
backed get_or_create_session; activity check is last_prompt_tokens) and
the sidecar-note reset path (context notes now ride turn_sidecar_notes
instead of prepending to context_prompt).
Long-lived Slack/Discord channels/threads lose their context on
daily/idle session resets, and the agent can bind a new request to an
unrelated recent session (observed: a Discord thread reset caused a PR
in the wrong repository). Record prev_session_id when an auto-reset
replaces a session with real activity, persist it, and append a
deterministic one-line hint to the auto-reset context note pointing the
agent at session_search for that specific prior session. No LLM calls,
no channel-history APIs, no extra DB lookups; other platforms and
activity-free resets are untouched.

Salvaged from PR #45702 (heartbeat half). A multi-minute turn showed a
static 'is thinking...' assistant status that reads as stuck and provokes
mid-turn 'you there?' pings. Derive the fallback status label from the
turn's elapsed time (>=30s → 'still working… (NmSSs)'), riding the
existing _keep_typing refresh — zero extra API calls.
Ported onto the current plugin adapter: the start time rides the tracked
_active_status_threads entry (workspace-scoped key), so it shares the
existing bounds/eviction and resets when stop_typing clears the status.
Explicit live-status phrases (set_status_text) and configured
typing_status_text always win; only the built-in default label changes.
The PR's other half (top-level channel follow-up coalescing) is NOT
included — dispatch semantics changed on main (busy-input active-turn
redirect, #30170 demotion) and need a fresh design pass.

Issue #47699 reported Slack /goal continuations being enqueued by
_post_turn_goal_continuation -> _enqueue_fifo but never drained until the
next real inbound message woke the session. On the current tree the
continuation lands in the adapter pending slot while the
_process_message_background frame is still live, so the in-band pending
drain (and the finally-block late-arrival drain) spawns the follow-up
turn automatically — the reported stall is not reproducible on main.
Pin the two halves of that contract so it can't silently regress:
1. a continuation placed in the FIFO during the handler frame is
consumed as a second turn without any new user message, and
2. the runner's goal hook enqueues under the same session key the
adapter drain resolves (key mismatch would orphan the event).
Refs #47699. Reported-by: joesu-angible
process(wait) marks a completion consumed and returns the exit code +
output inline. The gateway process watcher's agent-notify branch honored
that (skipping the synthetic agent turn), but its skip FELL THROUGH to
the plain text-notification branch, which re-sent the same completion to
the chat as a raw '[Background process ... finished with exit code ...]'
message — a duplicate delivery of output the agent had already read and
was summarizing (observed on Slack with
display.background_process_notifications: all, but platform-agnostic).
Guard the raw-notification branch on is_completion_consumed(), same as
the agent-notify branch. poll() stays read-only and never marks consumed
(#10156), so status checks still can't suppress autonomous delivery.

* fix(desktop): hide persisted agent-only history scaffolding
Filter verification-stop nudges and context-compaction handoffs at the

* fix(timeline): persist typed display events
* fix(timeline): strip display-only fields from provider payloads, preserve through rewrites, fix /resume display history
Three review findings from PR #69771:
1. Provider payload leak: display_kind and display_metadata were forwarded
to the provider API as unknown message fields. Strict OpenAI-compatible
backends can reject the next request after a model switch or resumed
typed event. Strip both from the per-request api_msg copy in
conversation_loop alongside the existing api_content pop.
2. Rewrite/import data loss: _insert_message_rows preserved display_kind
but silently dropped display_metadata. After replace_messages,
archive_and_compact, or session import, async-delegation completion
events lost their task counts and fell back to generic display text.
Add display_metadata to the INSERT columns and bind tuple.
3. CLI /resume stale recap: startup --resume A set _resume_display_history
from A's lineage. A subsequent in-session /resume B loaded B only into
conversation_history via get_messages_as_conversation, leaving the stale
A display projection. _display_resumed_history preferentially read the
stale attribute, showing A's recap for B. Switch /resume to
get_resume_conversations and update _resume_display_history alongside
conversation_history.
Tests: 890 Python (5 files), 35 desktop TS — all green.
* feat(tui): render typed display events as ◈ markers in the Ink TUI
The TUI was not handling display_kind at all — model switch markers and
async delegation completions rendered as opaque user messages with the
full [System: ...] text, and hidden compaction handoffs were visible.
Wire display_kind through the full TUI chain:
- _history_to_messages (tui_gateway/server.py) forwards display_kind
and display_metadata to the gateway transcript payload.
- GatewayTranscriptMessage (gatewayTypes.ts) gains both fields.
- Msg.kind (types.ts) gains 'event' value.
- toTranscriptMessages (domain/messages.ts) maps:
- hidden → skip entirely
- model_switch → event "model changed"
- async_delegation_complete → event "N background agents finished"
(or "background agent work finished" without metadata)
- messageGroup (blockLayout.ts) routes event to its own group, with
SELF_SPACED + PAINTS_TRAILING_GAP so it owns its margins.
- messageLine.tsx renders event-kind as a dim ◈ marker with no gutter,
matching the CLI's ◈ event rendering.
- 4 new TUI tests for hidden/model_switch/async_delegation mapping.
TUI typecheck: clean. TUI lint: 0 errors (2 pre-existing warnings).
TUI tests: 9 passed (1 pre-existing failure on main, unrelated).
Claude-on-Bedrock already gets prompt caching via the AnthropicBedrock
SDK path. This adds it to the raw Converse API path used for non-Claude
models (Amazon Nova, and Claude when bearer-token auth forces Converse
routing, #28156) — a conservative model allowlist inserts cachePoint
blocks after tools, system, and the message before the newest turn, and
extracts cacheReadInputTokens/cacheWriteInputTokens into usage so cost
accounting picks them up through the existing Anthropic-style fallback.

Follow-up hardening on top of the C14 cherry-picks (#57860/#44026/#66742/#60009):
- Slack file downloads (_download_slack_file/_download_slack_file_bytes)
now require an https URL on a Slack CDN host (files.slack.com,
*.slack.com Enterprise Grid, *.slack-files.com legacy shares) before
attaching the bot token. url_private/url_private_download only ever
point at the Slack CDN, so a forged file object from a malicious
workspace app or compromised event stream pointing the Bearer-token
download at an arbitrary PUBLIC host (token exfiltration) is now
refused — a hole #44026's generic private-IP SSRF check alone could
not close.
- The same two download paths now use create_ssrf_safe_async_client
(from #57860) so the preflight-validated hostname is resolved once,
validated, and dialed by IP — closing the DNS-rebinding TOCTOU window
for the token-bearing inbound fetches as well.
- #60009's slack_tokens.json permission warning is generalized into
utils.warn_if_credential_file_broadly_readable() (POSIX-only,
fail-quiet) and wired into the other read path with the same gap:
google_chat's load_user_credentials(). google_chat already writes
0o600 via _write_private_json; the read-time warning covers
hand-provisioned/legacy files. Nothing in-repo writes
slack_tokens.json (user/OAuth-provisioned), so there is no write
path to chmod for Slack.
Security tests both directions: non-CDN/lookalike/http URLs and
connect-time DNS rebinds are blocked before any TCP connect; real
files.slack.com, Enterprise Grid, and slack-files.com URLs still reach
the network layer; 0o600 files stay silent while 0o644/0o640 warn with
a chmod hint. A/B: all 10 new download-guard tests fail with the
hardening reverted and pass with it applied.
`SlackAdapter._fetch_thread_context` formats each prior thread message as
`{name}: {msg_text}` and joins them with newlines into the block the call
site prepends *raw* into the model turn (`text = thread_context + text`).
Both fields are attacker-influenceable — any thread participant sets their
own Slack display name and message text — and neither was neutralized, so
an embedded newline let a thread message break out of its line and pose as
a fresh markdown section (a fake "## SYSTEM" / "## Override" heading) inside
the context the model reads when first mentioned mid-thread.
This is the same indirect-prompt-injection vector already closed for the
sibling untrusted sinks: the sender-name prefix
(`neutralize_untrusted_inline_text`), the reply quote, and the relay
channel-context renderer. The Slack thread-context backfill — the default
whenever the bot is mentioned in a thread with no active session — was the
missed sink. (The existing `[unverified]` tagging marks *who* a message is
from; it does nothing about newline structure, so an authorized sender can
inject just as easily.)
Flatten both fields with `neutralize_untrusted_inline_text` before
interpolation. The body uses `max_chars=0` so message text is not truncated
(thread context caps the message *count*, never per-message length); the
display name keeps the default bound. `parent_text` keeps the raw message
(its own reply-context sink neutralizes separately). A well-behaved message
is preserved byte-for-byte.
Adds a regression test covering a hostile display name, a hostile message
body, benign passthrough, and the no-truncation guarantee.
_download_slack_file and _download_slack_file_bytes fetched Slack-supplied URLs with the bot token attached and follow_redirects=True, but without the is_safe_url pre-flight check or per-redirect guard that the outbound send_image path already uses. A URL that resolves to (or 3xx-redirects into) a private/internal address could reach internal services and leak the bot token (CWE-918). Add the same pre-flight + _ssrf_redirect_guard hook to both inbound sibling paths.
Several platform fetch paths called is_safe_url before constructing ordinary httpx clients, leaving a second DNS lookup at connection time. This preserved the rebinding window for Slack batch images, Feishu documents, Telegram URL-photo fallback, and WeCom remote media.
Route each path through create_ssrf_safe_async_client and the shared redirect guard so direct connections validate and dial vetted IPs while configured proxies remain an explicit trusted egress boundary. Add per-path regressions that change DNS from public at preflight to metadata at connect time.
The Skills Hub provenance fixture intentionally serves content over loopback. Opt that test-scoped server into private-address access so it keeps exercising the real HTTP transport without weakening production blocking.

Install connect-time DNS validation for Hermes-owned direct httpx clients so SSRF-sensitive fetch paths dial a vetted IP instead of re-resolving after preflight. This preserves Host/SNI semantics for direct HTTP(S) connections and keeps proxy routing as an explicit trusted egress boundary.
Wire the guarded clients into media cache downloads, vision downloads, Skills Hub direct/raw fetches, and platform attachment fetch paths that already perform SSRF preflight and redirect validation.

CI shards run without the slack extras; the two #64267 tests import the
real SDK (SlackApiError, the lazy-rebind path) and errored with
ModuleNotFoundError. Skip on bare environments — classification coverage
for stdlib exception types (OSError/TimeoutError/cert errors) still runs
everywhere.
Widening for #24117 ('is thinking...' stuck after the response was
sent): the stuck-thinking class is a missing-cleanup-on-error-path bug.
send()'s status clear was gated on thread_ts already being resolved and
on reaching the normal post-message path, which left the Slack
Assistant status visible when a turn ended through any sibling exit:
- exception BEFORE _resolve_thread_ts (slash-context handling,
formatting, DM resolution) — the 'if thread_ts: stop_typing' clear
never ran
- empty/whitespace-only final response (no_text guard early-return)
- ephemeral slash replies (Slack only auto-clears assistant status on
real thread replies; ephemerals never count)
Add _clear_thread_status_quietly() — a best-effort stop_typing wrapper
that never masks the caller's SendResult — and wire it at every send()
exit plus the finalize paths of edit_message. stop_typing already
handles the untracked-thread fallback (clearing an unset status is a
no-op on Slack's side), so this is pure coverage widening.
Also add the #18859 unit tests for _resolve_progress_thread_id's new
reply_in_thread gate (synthetic-thread drop, real-thread keep, event-id
fallback suppression, default unchanged).
A/B: 3 of the 4 new status-clear tests fail with the adapter widening
reverted and pass with it applied; the fourth pins the existing
cleanup-must-not-mask-result contract.
When reply_in_thread=false, top-level channel events carry their own
message ts as metadata.thread_id for session keying. Calling
assistant.threads.setStatus on that ts activated a Slack assistant
thread ('is thinking...') before the actual response was sent, and the
flat reply then never cleared it.
send_typing now routes through the same _resolve_thread_ts synthetic-
thread guard as message sending, and the gateway threads message_id
through progress/status metadata so the adapter can distinguish real
threads from synthetic top-level session keys.
Reapplied from #18859-sibling PR #17184 by @dorukardahan (both commits:
fix + progress-metadata test) onto current main via 3-way apply — the
original patched gateway/platforms/slack.py, moved to
plugins/platforms/slack/adapter.py in the plugin migration.
Progress/status callbacks (context-pressure, compression retries,
model fallback) route through _send_or_update_status_coro, which
edits the previous bubble for the same status_key when the adapter
implements send_or_update_status — but only Telegram did. On Slack
every status event posted a fresh thread message, so a compression
retry loop spammed a dozen out-of-order bubbles into the thread
('Context too large 1/3... 2/3... 3/3', fallback switches, etc.).
Implement send_or_update_status on the Slack adapter following the
Telegram pattern (#30045): first call posts and caches the message ts
per (channel, thread, status_key); subsequent calls edit that message
via chat.update. Edit failure drops the cached ts and falls back to a
fresh send. Cache is FIFO-bounded.
Covers cluster C1-images (#69185, #32315, #66136):
- _slack_file_marker unit tests: typed markers per mimetype family,
hostile-filename sanitization (newlines/brackets can't fake context
structure).
- _render_message_text appends markers; a caption-less image post no
longer vanishes from thread context.
- Cold-start hydrate integration: prior-message images surface as
markers in channel_context; the thread root's image is downloaded,
delivered as media_urls, and upgrades message_type to PHOTO.
- Failure path: root-image download failure degrades to the marker,
never blocks the turn.
- Bounds: root delivery capped at _THREAD_ROOT_IMAGE_MAX; non-image
root attachments stay marker-only (no download).
- One-time delivery: active thread session skips the hydrate → no
re-download/re-delivery on later turns.
- Composition: the trigger's own event files still ride alongside a
delivered root image; Slack Connect stubs resolve via files.info;
the collector never issues its own conversations.replies call.
- Delta refresh (#23918 path): images in new replies past the watermark
surface as markers, with no root re-download.
A/B: 14 of 15 tests fail with the adapter fix reverted, all pass with
it applied.
#58478's caplog test predates main's unlabeled-bot users.info probe
(#69xxx wave-2 gating): events without client_msg_id now hit
_resolve_user_is_bot, which the fixture's mock client doesn't wire up
(AttributeError on _user_is_bot_cache). Real human-authored Slack
messages carry client_msg_id — add it to the fixture so the test
exercises the intended block-extraction path.
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.
