+"""Shared helper for loading platform-plugin ``adapter.py`` modules in tests.
+
+Every platform plugin under ``plugins/platforms/<name>/`` ships its own
+``adapter.py``. If two tests independently do::
+
+    sys.path.insert(0, "plugins/platforms/irc")
+    from adapter import IRCAdapter
+
+    sys.path.insert(0, "plugins/platforms/teams")
+    from adapter import TeamsAdapter
+
+…then whichever collects first in an xdist worker wins
+``sys.modules["adapter"]``, and the other raises ``ImportError`` at
+collection time. The fallout cascades across unrelated tests sharing that
+worker because ``sys.path`` is still polluted.
+
+Use :func:`load_plugin_adapter` instead of ad-hoc ``sys.path`` tricks.
+It loads the adapter from an explicit file path under a unique module
+name (``plugin_adapter_<plugin_name>``), so it cannot collide with any
+other plugin's adapter module.
+
+The ``tests/gateway/conftest.py`` guard rejects the anti-pattern at
+collection time so this can't regress when new plugin adapter tests are
+added.

+
+The ``_ensure_telegram_mock`` helper guarantees that a minimal mock of
+the ``telegram`` package is registered in :data:`sys.modules` **before**
+any test file triggers ``from plugins.platforms.telegram.adapter import ...``.
+
+Without this, ``pytest-xdist`` workers that happen to collect
+``test_telegram_caption_merge.py`` (bare top-level import, no per-file
+mock) first will cache ``ChatType = None`` from the production
+ImportError fallback, causing 30+ downstream test failures wherever
+``ChatType.GROUP`` / ``ChatType.SUPERGROUP`` is accessed.
+
+Individual test files may still call their own ``_ensure_telegram_mock``
+— it short-circuits when the mock is already present.
+
+Plugin-adapter anti-pattern guard
+---------------------------------
+Tests for platform plugins (``plugins/platforms/<name>/adapter.py``)
+must load the adapter via
+:func:`tests.gateway._plugin_adapter_loader.load_plugin_adapter`, not by
+adding the plugin directory to ``sys.path`` and doing a bare
+``from adapter import ...``. The guard at the bottom of this file
+scans test module ASTs at collection time and fails collection with a
+pointer to the helper if the anti-pattern is detected.
+
+Rationale: every plugin ships its own ``adapter.py``, and two tests each
+inserting their plugin dir on ``sys.path[0]`` race for
+``sys.modules["adapter"]`` in the same xdist worker. Whichever collects
+first wins; the other fails with ``ImportError``, and the polluted
+``sys.path`` cascades into unrelated tests. See PR #17764 for the
+incident.

+Three modes:
+  1. Generic OAuth2 client_credentials when gateway.idp.token_url (or

+     (air-gapped / self-hosted-IdP).

+     The metadata-server pattern (e.g. Domino's $DOMINO_API_PROXY/access-token).
+  2. Nous Portal (resolve_nous_access_token) otherwise — the default.
+
+The HTTP calls and the Nous resolver are monkeypatched; these prove the mode

+"""Regression: the transport's timeout-shaped RESULT is ambiguous, not a
+rejection (PR 85796 review round 2, finding 1).
+
+The production ws transport does not raise on ack timeout — it returns
+{"success": False, "error": "relay outbound timed out", "ambiguous": True}.
+The round-1 fixes keyed ambiguity handling entirely on the exception
+channel, so the shape production actually produces was misclassified:
+
+  - a lost SEAL ack skipped the idempotent retry and fell straight to a
+    plain send (duplicate final whenever the seal had actually applied);
+  - a lost FRAME ack was treated as a definite connector rejection and
+    DISARMED interception — frozen native stream beside a plain final
+    (the original G-D1 ambiguous-ack defect, moved to the result channel).
+
+Contract now: transport tags ack-timeouts ambiguous=True (fail-fast
+closing/not-connected results stay unmarked — nothing was sent); the
+adapter retries the idempotent seal frame on ambiguous results exactly as
+for exceptions, and disarms interception only on definite rejections.

+"""A2 outbound capability action: the token-less ``follow_up`` op.
+
+Proves the gateway can act on a shared-identity capability (e.g. a Discord
+interaction follow-up token) WITHOUT ever holding the credential: it names the
+session it is in plus the capability ``kind``, and the connector resolves the
+real value from its vault and egresses. See gateway/relay/transport.py
+(send_follow_up) and docs/relay-connector-contract.md §4.
+
+The gateway side is what's exercised here (against the stub connector); the
+connector's resolve + tenant-match enforcement lives in the connector repo
+(resolveOutboundCapability). The key gateway-side guarantees:
+  - the wire action carries NO token (only session_key + kind + content),
+  - success/failure surfaces from the connector's resolve result,
+  - a failed resolve (absent/expired/tenant mismatch) returns success=False
+    with nothing for the gateway to retry with.

+"""Per-platform capability descriptors on the relay (multi-platform Phase 1.5).
+
+The bug class: one relay adapter fronts N platforms on one WS, but the
+capability surface (``MAX_MESSAGE_LENGTH`` / ``message_len_fn``) was a SCALAR
+from whichever descriptor resolved the handshake — so a Discord chat on a
+gateway whose primary identity was Telegram inherited Telegram's 4,096-char
+cap and over-sent into Discord's 2,000-char API 400 (observed live: 2,543 and
+2,641-char sends rejected).
+
+Covers:
+  - the transport accumulating one descriptor per platform (first = session
+    default, later frames must NOT overwrite it),
+  - the map resetting on a re-dial,
+  - RelayAdapter.max_message_length_for_chat / message_len_fn_for_chat
+    resolving from the chat's inbound platform,
+  - fallback to the scalar descriptor for unknown chats / transports without
+    the map,
+  - the stream consumer's _raw_message_limit honoring the per-chat cap.

+  - No ``scope_id``; isolation between chats comes from ``chat_id`` alone.
+  - Forum topics live inside ONE ``chat_id`` and isolate by ``thread_id`` (the
+    Telegram analog of Discord's per-scope isolation).
+  - Forum/thread sessions are shared across participants by default
+    (``thread_sessions_per_user=False``) — user_id is NOT appended in a thread.
+  - ``len_unit="utf16"`` (Telegram counts UTF-16 code units) and
+    ``markdown_dialect="markdown_v2"`` — distinct from Discord's chars/discord.
+
+If the descriptor or session-keying only worked for Discord, these fail.

+Reported symptom (live): agent responses stream progressively (edit-based) in a

+
+Root cause: a DM turn's streaming reply is sent with

+``initial_reply_to_id`` — its edit anchor). The connector's slackRestSender maps
+a raw ``reply_to`` to a Slack ``thread_ts``, so a plain DM reply gets threaded

+first send loses the progressive edit streaming the user sees in a real thread.

+thread anchor; the relay lane had no such disambiguation.

+"""Slack relay: interactive prompts follow the turn's thread stamp.
+
+The threading MODE (flat DM vs thread-per-message) is decided in exactly ONE
+place: run.py's ``_resolve_progress_thread_id``, which reads
+``platforms.slack.extra.reply_in_thread`` and encodes the verdict into the
+outbound ``metadata`` stamp:
+
+  * flat mode  -> the synthetic self-anchor is suppressed in run.py, so prompt
+    metadata arrives with NO ``thread_id`` and the card posts at the DM root;
+  * thread-per-message (default) -> ``metadata.thread_id`` is stamped for the
+    whole turn; on the FIRST turn it legitimately equals the triggering
+    message's ts (the synthetic root IS the thread).
+
+The prompt lane must TRUST that stamp, like ``_resolve_reply_to_for_send``
+does. Re-deriving the mode here (the old unconditional
+``thread_id == message_id`` strip) exiled the approval card and its
+resolved-state swap to the DM root while progress bubbles honoured the thread
+(the 2026-07-27 mixed-placement report).
+
+These are behaviour-contract tests: they assert how the outbound ``prompt``
+frame relates to the inherited thread metadata (the invariant the connector
+depends on), not a snapshot. They drive the REAL ``RelayAdapter`` +
+``StubConnector`` end to end.

+"""Relay Phase 4 tests — thread lifecycle ops, reply_to enrichment parse,
+auto-thread markers, and the hello command manifest.
+
+Covers:
+  - create_handoff_thread routes through `thread_create` (op-gated; None
+    fallback contract preserved for the handoff watcher);
+  - rename_thread routes through `thread_rename` with the
+    only_if_current_name guard on the wire (op-gated; False on decline);
+  - the relay semantic-rename lane parity: a relay source carrying the
+    connector-stamped auto-thread markers satisfies the same field contract
+    the native _is_discord_auto_thread_lane reads;
+  - _event_from_wire maps reply_to {text,author,is_own} onto the native
+    MessageEvent reply-context fields and the auto-thread markers onto
+    SessionSource;
+  - the ws transport sends command_manifest on the DISCORD hello only;
+  - the manifest builder satisfies Discord CHAT_INPUT naming rules.

+"""Regression: per-TURN stream/card identity (PR 85796 review, B2).
+
+Keying coordination state on the thread anchor alone is simultaneously:
+
+  - too coarse: two parallel turns replying INSIDE ONE Slack thread share
+    thread_ts — turn A's final sealed turn B's stream with A's content
+    while A's own stream stayed open (live probe on the review branch);
+  - too fragile: a flat DM with no thread metadata degraded to the bare
+    chat id, re-creating the original finding-#10 collision.
+
+The key now prefers the triggering inbound message id (message_id /
+reply_to_message_id — per-turn by construction), falling back to the
+thread anchor, then the bare chat. Legacy callers with placement-only
+metadata still seal via _match_open_draft's single-open-stream fallback,
+but NEVER when multiple streams are open (a duplicate message is
+recoverable; sealing someone else's stream is not).

+"""Unit tests for relay voice-note + per-attachment media-type mapping.
+
+The relay contract gained ``message_type: "voice"`` (connector PR: voice
+notes on Discord/Telegram/WhatsApp classify distinctly from audio-file
+uploads). The gateway side has two obligations:
+
+1. ``MessageType("voice")`` must parse — it already does, since the enum
+   predates the wire value — and
+2. the connector's rich ``media[]`` array (each entry carries the
+   per-attachment ``mime``) must land on ``event.media_types`` so run.py's
+   per-attachment classifiers (``_event_media_is_stt_input``, image vs
+   document routing) work for relayed events, not just native adapters.
+
+Live-verified failure (staging 2026-08-26): a voice note arrived as
+``MessageType.AUDIO`` with ``media_types == []`` — STT never fired and the
+agent got a "the user sent an audio file attachment" note instead.

+"""Regression tests for the relay WS transport hardening fix.
+
+Coatue incident 2026-08-18: WAN latency / event-loop stalls tripped the
+websockets library's default 20s pong deadline, closing customer-gateway
+sockets with `1011 keepalive ping timeout`. On top of the spurious close,
+every in-flight outbound then hung for the full _outbound_timeout_s (~30s)
+because only disconnect() failed pending futures — an unexpected socket drop
+left them stranded — and sends issued while the reconnect supervisor was
+backing off registered futures no reader could ever resolve.
+
+Three hardening changes under test:
+  1. _read_loop fails all in-flight _pending futures on ANY exit path with
+     the dict shape callers expect ({"success": False, ...}).
+  2. _request_response fails fast while the reconnect supervisor is
+     mid-redial (live supervisor task = the redial window).
+  3. connect() passes explicit WAN-friendly keepalive tuning
+     (ping_interval=30, ping_timeout=60) to websockets.connect().

+"""Regression test for #10710 — stale context summary leak after auto-reset.
+
+The gateway agent cache is keyed on the stable chat ``session_key``, which does
+NOT change when a session is auto-reset (daily schedule / idle timeout /
+suspended). So unless the cached agent is explicitly evicted on auto-reset, the
+NEXT message reuses the old ``AIAgent`` instance — carrying its
+``context_compressor._previous_summary`` — and prior-conversation content leaks
+into the new session's compaction summaries.
+
+Manual ``/reset`` and the compression-exhausted path (#9893) already evict the
+cached agent. This pins the matching eviction onto the auto-reset cleanup block
+in ``_handle_message_with_agent``.
+
+These are AST invariants — load-bearing pins that fail if the eviction is
+removed from the cleanup block (mirrors

+"""Regression tests for #13121 — gateway restart/shutdown must persist an
+in-flight (interrupted) turn's transcript to the SQLite session store so the
+immediate pre-restart context survives ``load_transcript()`` on resume.
+
+The bug: every normal/graceful turn exit funnels through
+``turn_finalizer.finalize_turn`` which calls ``_persist_session`` →
+``_flush_messages_to_session_db`` (the only place a turn is written to
+state.db).  During the tool loop only the *in-memory* ``_session_messages``
+reference is refreshed per round — there is no incremental SQLite flush
+mid-turn.
+
+When the gateway drain times out it marks the session ``resume_pending``,
+interrupts the running agents, waits a short grace window, then tears them
+down via ``_finalize_shutdown_agents`` → ``_cleanup_agent_resources``.  An
+agent blocked in a tool call that does not abort within the grace window
+never reaches ``finalize_turn``, so its in-flight tool rounds live only in
+``_session_messages`` and are never written to state.db.  On resume,
+``load_transcript()`` (state.db is now the canonical store — the legacy
+JSONL fallback was dropped) returns the pre-turn state, dropping the
+immediate pre-restart turn.
+
+The fix flushes ``_session_messages`` to the session DB in
+``_finalize_shutdown_agents`` before teardown.  The flush is idempotent
+(identity-tracked in ``_flush_messages_to_session_db``), so agents that DID
+finish gracefully re-flush nothing.
+
+These tests exercise BOTH a lightweight unit path (the flush hook is invoked
+with the in-flight messages) AND a true E2E path (a real ``AIAgent`` flush
+against a real ``SessionDB`` in a temp ``HERMES_HOME``, read back through the
+real ``SessionStore.load_transcript``).

+"""Regression tests for #25107: gateway /model switch left a stale
+``base_url``/never persisted ``api_mode`` in config.yaml when switching to a
+custom provider whose resolver returned an empty ``base_url``.
+
+Root cause: both the picker-tap path (``_on_model_selected`` in
+``gateway/slash_commands.py``) and the typed ``/model X --global`` path
+(``_finish_switch``) guarded the persist block with two *independent*
+``if``s:

+
+For a NAMED provider the second ``if`` always clears any stale value, so the
+bug was invisible there. But for a ``custom`` provider with an empty
+resolved ``base_url``, NEITHER branch fires: the old base_url survives
+untouched, and ``api_mode`` was never written to ``model_cfg`` at all in
+either branch (only present in the in-memory session override).
+
+Fix: an explicit set-or-clear for both fields when the target provider is
+custom, so a genuine switch always leaves config.yaml coherent with the
+resolved result.

+"""Regression tests for #35809 — compression-exhaustion auto-reset loop.
+
+After compression is exhausted the gateway auto-resets the session so the
+next message starts on a fresh, empty conversation (#9893 / #10063). That
+guarantee regressed once the Telegram topic-binding heal landed
+(#20470 / #29712 / #33414):
+
+    1. Compression rotates ``session_entry.session_id`` to an oversized
+       compressed *child* session mid-turn and the agent-result sync rewrites
+       the ``(chat_id, thread_id) -> child`` topic binding.
+    2. ``reset_session`` swaps in a clean, parentless session — but its return
+       value was discarded and the topic binding was left pointing at the
+       bloated child.
+    3. On the next inbound message in that topic, the binding-heal walk
+       ``switch_session``'d the freshly-reset lane *back* onto the bloated
+       child, ``load_transcript`` reloaded the oversized transcript, and
+       compression exhaustion re-fired — a new session id every loop.
+
+The fix captures the fresh entry from ``reset_session`` and re-syncs the
+topic binding to it (a no-op on non-topic lanes).
+
+Two tests:
+
+* ``TestAutoResetBlockReSyncsBinding`` — an AST invariant on
+  ``gateway/run.py`` (mirrors ``test_compression_session_id_persistence.py``):
+  the compression-exhausted auto-reset block must capture
+  ``reset_session(...)`` and call ``_sync_telegram_topic_binding`` afterward.
+  This is the load-bearing regression pin.
+* ``TestAutoResetLoadsCleanContext`` — a behavioral contract on the real
+  ``SessionStore``: after ``reset_session`` the next turn loads an EMPTY
+  transcript for the new session_id, never the bloated child's transcript.

+"""Regression test for #48031 — /model switch lost after session auto-reset.
+
+When `/model X` is the FIRST message after an idle/daily/suspended auto-reset,
+it stores a session model override but the `was_auto_reset` flag is left True
+(the slash-command path doesn't pass through the message handler that consumes
+it). On the NEXT regular message, the auto-reset cleanup block in
+`_handle_message_with_agent` pops the freshly-stored override BEFORE the flag
+is consumed, so the switch is silently lost and resolution falls back to the
+config default — while the session DB still shows the switched model (a
+two-sources-of-truth divergence).
+
+The fix consumes `was_auto_reset` at two sites:
+  1. the cleanup block in gateway/run.py captures it into a local and sets the
+     attribute False immediately (so it can't re-fire next message);
+  2. the slash-command model path in gateway/slash_commands.py consumes it
+     before storing the override (so a /model-first-after-reset isn't wiped).
+
+These are AST invariants — load-bearing pins that fail if either consume is
+removed (mirrors test_35809_auto_reset_clean_context.py's approach).

+``_cleanup_agent_resources`` (agent.close() tears down terminal sandboxes /
+browser daemons / background processes; shutdown_memory_provider() may do
+SQLite / network IO via a memory plugin) was still called INLINE on the event
+loop from three other places:

+  * ``_handle_message_with_agent`` cache-hygiene re-eviction — live loop
+  * ``_finalize_shutdown_agents`` / ``stop()`` idle-cache loop — shutdown
+
+A wedged provider on any of these froze the whole loop: the bot went silent,
+the runtime-status ``updated_at`` heartbeat stopped advancing (the symptom the
+reporter's watchdog keyed on), and SIGTERM could not be serviced (requiring
+``kill -9``).
+
+The fix routes all four call sites through ``_cleanup_agent_resources_off_loop``
+which offloads to a worker thread under a bounded ``asyncio.wait_for``, so the
+loop is never blocked and a stuck teardown degrades gracefully.
+
+These tests drive that shared helper directly — it is the single chokepoint
+every fixed call site now uses.

+
+When gateway.multiplex_profiles is on and TELEGRAM_BOT_TOKEN lives only in a
+secondary profile's .env, the default-profile primary adapter used to start
+with an empty token, log "No bot token configured", and queue an infinite
+reconnect loop. Secondary profiles already load under _profile_runtime_scope;
+this suite locks the complementary primary-path fixes:
+
+1. load_gateway_config_for_runner reloads under the default profile secret scope
+   when multiplex is on (so default .env tokens resolve like secondary loads).
+2. Primary startup skips token platforms that still have no credential under
+   multiplex instead of connecting-and-failing forever.

+
+The gateway's ``_cleanup_agent_resources`` (the cleanup chokepoint that
+``/reset`` and every other gateway session rotation invokes to tear down the
+cached agent) used to call ``shutdown_memory_provider()`` WITHOUT first
+draining the memory manager's serialized background write worker.
+``shutdown_memory_provider`` -> ``shutdown_all`` only gives that worker a
+bounded (~5s) drain and abandons whatever is still queued past it, so a
+/reset could silently drop writes the session had already handed off — the
+next session then loaded stale memory.

+The CLI exit path already drains via ``MemoryManager.flush_pending`` before
+shutdown (cli.py); these tests pin the same contract on the gateway path.

+"""Regression tests for #73771 — session-wide MEDIA dedup swallowing
+explicit resend requests.
+
+The history-dedup guard in the delivery pipeline used to drop ANY
+``MEDIA:<path>`` whose path appeared earlier in the session transcript —
+unconditionally, silently, for the whole session lifetime. A user asking
+"send me that file again" got a reply reading "here it is" with no
+attachment and nothing in the logs.
+
+Fix (salvaged from PR #74158 by @webtecnica, widened to the streaming
+sibling):
+
+* Non-streaming (``BasePlatformAdapter._process_message_background``):
+  explicit MEDIA tags are NO LONGER filtered against history. Stale
+  auto-appended tags are already deduped upstream in
+  ``_collect_auto_append_media_tags``.
+* Streaming (``GatewayRunner._deliver_media_from_response``): same filter
+  removed — that rescan is explicit-only by design (#20834), so anything
+  it finds is a deliberate attachment request.
+* Bare local file paths (auto-detected, not explicit) KEEP the history
+  dedup on the non-streaming path, and the suppression is now logged.

+"""Connect-failure classification + reconnect-queue escalation (OOF-156).
+
+Four platforms (telegram, discord, photon, email) used to funnel every
+startup failure into an indefinitely-retried state — including permanent
+failures like revoked tokens, missing privileged intents, and sidecar deps
+that can never install on an immutable image. Fleet triage found agents that
+had been silently "retrying" for weeks (OOF-151/152/153).
+
+Two-part fix, both covered here:
+
+1. Per-adapter classification: auth/permission/deterministic failures are
+   classified by exception TYPE (never message text) as ``retryable=False``
+   so they exit via the existing non-retryable fatal path.
+2. Gateway escalation: platforms continuously in the reconnect queue past a
+   threshold get ``needs_attention`` flagged in runtime status. Retries never
+   stop — the deliberate removal of auto-pause stands (a transient outage
+   must self-heal without operator action).

+The gateway reconnect watcher forwards ``is_reconnect=True`` to every

+``QQAdapter`` and was only discovered after messages stopped flowing on

+To prevent this class of bug from regressing, we statically parse every
+``adapter.py`` under ``gateway/platforms/`` and ``plugins/platforms/``

+session id per request even when the request declared its conversation with
+``X-Hermes-Session-Key``.  Every conversation-affinity hint Hermes sends is

+
+These tests pin the identity contract itself rather than the four consumers:

+
+When gateway.multiplex_profiles is on, get_secret fails closed without a
+profile secret scope. Requests with a ``/p/<profile>/`` prefix are scoped by
+``_profile_scope(profile)``, but plain requests on the default listener used
+to get ``nullcontext()`` — so agent runs crashed with UnscopedSecretError on
+their first credential read (e.g. OPENROUTER_BASE_URL). ``_profile_scope``
+now enters the DEFAULT profile's runtime scope when multiplex is active and
+no profile was requested.
+
+Adapted from PR #61283 by @giggling-ginger (originally targeting a
+pre-``_profile_scope`` helper); no live gateway or network.

+"""A ``/p/<profile>/`` prefix on a non-multiplexed gateway must not misdeliver.

+The prefix is an address: the caller is naming WHICH agent the request is

+off and answered as the process's own (single) profile — so a request
+explicitly addressed to one agent was silently answered by a different one.
+Observed live (Aug 2026): ``hermes peer dm mini/researcher`` was answered by
+the mini's *default* agent, with no error on either side, because the mini
+runs one LaunchDaemon per profile and only the default daemon hosted an
+api_server.
+
+The contract now: with multiplexing off, a prefix naming this process's own
+profile is honored (peers address single-profile daemons this way without
+knowing the host's topology); any other name fails closed with the existing
+404, because a wrong-agent answer is strictly worse than an error.

+"""Regression test for approval prompt credential redaction (issue #48456).
+
+When Tirith flags a command for containing a credential-shaped pattern, the
+gateway approval prompt must redact the credential from the command text
+before sending it to the chat platform. Without this fix, the raw command
+(with the credential in plaintext) is sent verbatim to Telegram/Discord/etc.,
+undoing Tirith's redaction one layer up.
+
+The redaction is wired through the module-level ``_redact_approval_command``
+seam. These tests bind that seam -- the production wiring -- not just the
+underlying ``redact_sensitive_text`` helper, so they fail if the redaction
+call is removed from either approval path.
+
+Credential fixtures are built at runtime from a benign prefix + a run of

+send is AMBIGUOUS (possibly delivered). The gateway must NOT fall back /
+re-send; the prompt registration stays live so the user's tap on the
