fix(relay): authorize send_message targets and surface egress declines (P5) (#99220)
* fix(relay): authorize send_message targets and surface egress declines
P5 of the relay egress-authorization workstream. The relay path
authenticated the SENDER but never authorized the DESTINATION, and the
gateway compounded it from both ends.
(a) send_message could silently name an arbitrary relay target. Its
`target` parameter is free-form ('platform:chat_id'), so a model could
name ANY chat id and the gateway would emit an outbound frame for it.
gateway/relay/egress.py adds an attestation floor: a relay-routed
destination must have a provenance this gateway can show -- the
operator's home channel, the channel directory, or its own gateway
session origins. Anything else is refused HERE, with a visible tool
error naming the target, before a frame is written. Non-relay platforms
and platforms served by a live native adapter in this process are
untouched (same precedence resolve_delivery_transport applies).
(b) Connector declines were swallowed into apparent successes. The
connector's egress floor answers an unauthorized destination with a
DEFINITE failure whose text is deliberately uniform (F-005). Several
relay lanes degrade a *transport drop* by design and were degrading an
*authorization refusal* the same way:
- _send_media returned None, sending the caller into
BasePlatformAdapter's text fallback -- a DIFFERENT op re-addressed at
the very chat the connector had just refused.
- _send_prompt returned None, so exec-approval / slash-confirm /
clarify reported "relay prompt op unavailable" (a wrong reason) and
ran their numbered-text fallbacks into the refused chat.
- task_card_stop discarded the error entirely.
- typing / delete / react / thread ops degraded silently at debug.
is_egress_decline() classifies THAT a decline happened (never why --
the uniform text is not parsed for reasons) and requires a definite,
non-ambiguous failure, so a lost-ack retry is still a transport
outcome. Lanes with an error-carrying contract now report the decline
verbatim; cosmetic bool/None lanes still degrade but log it at WARNING.
Advisory progress drops that legitimately degrade are unchanged: the
task_card send lane, the draft ambiguous/except branches, and every
transport-exception path keep their existing fail-open behaviour.
Tests: 21 mutations of the production source, all KILLED.
* fix(relay): authorize the RESOLVED target; declines must not fall back
Review round 1 (independently confirmed by a second reviewer) found three
blockers. Two are fixed here; the third (B-2, Telegram @username) is a policy
decision left open deliberately.
B-1 — THE FIX CAUSED THE OUTAGE IT PREVENTED (tools/send_message_tool.py)
The P5(a) guard ran ABOVE Slack user->DM resolution, so it authorized the
internal pseudo-id `_parse_target_ref` emits (`user_name:ben`, `user:U...`).
Provenances only ever hold RESOLVED conversation ids, so a fully attested DM
was compared as a handle against a set of `D...` ids and refused:
base slack:@ben SENT head(before) slack:@ben REFUSED
Every Slack DM by handle was broken. Moved the guard below resolution; it now
authorizes the destination that is actually sent to, and the refusal names the
resolved id. Position is load-bearing, so it is commented as such and pinned:
reverting the move turns exactly the four new cases red.
B-3 — A DECLINE IS NOT A LANE FAILURE (gateway/run.py)
`_approval_send_outcome` had only sent/failed/ambiguous, so a connector
decline collapsed into `failed` — which is the cue to run the plain-text
fallback into the chat the connector had just refused. The adapter fix in the
previous commit improved the error STRING while user-visible behaviour stayed
identical to base; the commit message overstated it. Fixed properly:
- new `declined` verdict, recognised via the shared `is_egress_decline`
contract (not string sniffing at the call site)
- exec-approval returns without the text fallback
- slash-confirm suppresses the text reply AND clears the registration, so a
card that never rendered cannot capture the user's next message
`send_clarify` was already correct (returns early inside the adapter).
MUTATIONS (production source; both directions)
classifier never returns 'declined' -> KILLED (4 cases)
ALL failures classified as 'declined' -> KILLED (2 cases)
guard moved back above Slack resolution -> KILLED (4 cases)
decline CODE changed (review M05) -> KILLED
marker match made case-sensitive (M10) -> KILLED
M05 was a tautology: the test asserted the imported constant against itself,
so changing the constant could not fail it. The wire contract is now pinned as
a literal, because the connector stamps that exact string and a one-sided
change is a silent cross-repo break.
REGRESSION CHECK: the 12 failures + 1 collection error in this test selection
are PRE-EXISTING cross-test contamination — the identical set fails at
7cf86188ac. Verified by diffing the failing sets: no new failures, 363 -> 374
passed.
NOT FIXED (deliberate): B-2, Telegram `@username`. The Bot API resolves handles
at send time, so there is no id to compare and no canonicalization exists yet.
That is a policy decision, not a code move.
* fix(relay): fail CLOSED on guard faults; classify the structured decline
Third independent review. Two more blockers, both reproduced before fixing.
1. THE GUARD ITSELF FAILED OPEN (tools/send_message_tool.py:158)
`_authorize_relay_target` wrapped BOTH the import and the call in one
`except Exception: return None` — and None means AUTHORIZED at every call site.
So any runtime bug inside the guard silently switched the entire P5(a) boundary
off. Reproduced: with the guard raising, an unattested target sent.
The docstring already stated the correct intent ("must not fail closed on its
own IMPORT error") and the code did something broader. The two failures are not
the same: a missing gateway package means there is no relay egress to
authorize; a fault inside the guard means authorization did not happen. The
import is tolerated, the call is not — a guard that cannot answer refuses.
2. THE STRUCTURED DECLINE WAS THROWN AWAY (gateway/run.py)
The adapter preserves the connector's dict in `SendResult.raw_response`. My
previous commit rebuilt a dict from the error STRING, which loses two
contracts:
* a decline carrying `code: egress_declined` and NO text renders as
"relay egress declined" — no marker colon — so it classified as `failed`,
which is exactly the cue to run the fallback into the refused chat;
* `ambiguous: True` (lost ack) was flattened into a DEFINITE failure,
re-sending a card that may already be on the user's screen. That is the
duplicate-card bug the ambiguous verdict exists to prevent, reintroduced
by the fix meant to harden the same path.
Both call sites now classify `raw_response` when present, ambiguity first, and
fall back to the wire sentence only for connectors that send no structured
response.
I had fixed the text-marker path and tested only the text-marker path. Worth
naming: the review's probe was a shape my tests never produced.
MUTATIONS (production source)
guard fault returns None (fail open again) -> KILLED
classifier ignores raw_response -> KILLED (3 cases)
ambiguous treated as a definite failure -> KILLED (2 cases)
40 focused tests pass. Regression check vs be321faf27: identical 13-item
failing set (pre-existing cross-test contamination), no new failures.
STILL OPEN: B-2 / finding 3, Telegram `@username`. The reviewer is right that
this is a REGRESSION of an existing contract (#53573 added Bot API username
support), not merely an unspecified input, since relay provenance stores the
numeric chat id. Fixing it means resolving the handle before authorization, or
explicitly revoking the contract. That is a policy decision, not a code move,
and it is Ben's call.
* test(relay): pin M21 and M25, the survivors whose comments called them load-bearing
Round-2 review reported six unpinned survivors from round 1. Two guard real
behaviour and are now covered; the other four are cosmetic-lane warnings and
fail-open branches I am leaving documented rather than pretending to close.
M25 — thread-qualified session ids. `_session_ids` adds BOTH "chat:thread" and
the bare chat, because the connector authorizes the CHAT. Without the split a
gateway whose session origin is `-100999:77` cannot send to `-100999`, the chat
it is demonstrably already talking in. KILLED.
M21 — the generic `relay` plane must union every fronted platform, since a
relay session is filed under its LOGICAL platform. KILLED.
MY FIRST M21 TEST WAS THE DEFECT IT WAS TESTING FOR. I patched `_relay_fronted`
— the very function the mutation empties — so emptying it changed nothing the
test could see, and the mutation SURVIVED against a green test. Rewritten to
drive the real `relay_fronted_platforms()` through its env source
(`GATEWAY_RELAY_PLATFORMS`), which is how production learns it.
That is the same "the test verifies my stand-in" failure I have spent this
workstream removing from the connector harnesses, reproduced here in three
lines of Python. The tell was identical: a mutation that survives a test
written specifically to kill it.
334 tests pass.
NOT PINNED, deliberately: M03 (success-guard on a malformed dict), M24
(empty-target allowance — the one fail-open branch, reachable only when the
bare-platform path already resolved a home channel), M35/M36 (decline WARNINGs
on cosmetic lanes). All four are observability or defence-in-depth rather than
authorization, and the review agrees they are non-blocking.
* fix(relay): defer Telegram @username authorization to the connector (B-2)
Closes the last blocker. Two reviewers independently called this a REGRESSION
of the public-channel username support added in #53573, not an unspecified
input, and they were right: provenance stores RESOLVED numeric chat ids, so
comparing `@channel` against them could only ever refuse.
WHY THE GATEWAY CANNOT ANSWER IT. The guard fires only when there is no live
native adapter — i.e. relay-fronted deployments — and on exactly those the
CONNECTOR holds the bot token, not this process. There is no local way to turn
a handle into the numeric id. Refusing here is not "fail closed", it is "fail
always".
WHY DEFERRING IS SAFE. The destination is still authorized one layer out: the
connector's Telegram egress floor (gg#238, merged 743a7c2) classifies and
refuses unauthorized destinations after ITS resolution — the layer that closed
the reported vulnerability in the first place. Handles go from two guards to
one, the authoritative one, not to zero.
The carve-out is deliberately narrow and its EDGES are pinned, because the
failure mode of an exemption is silent widening:
telegram `@handle` -> deferred (the regression case)
telegram numeric id -> still guarded
matrix `@user:server` -> still guarded (telegram-only)
bare name, no `@` -> still guarded
attested handle -> normal path, attestation still consulted
MUTATIONS
carve-out widened to all platforms -> KILLED
carve-out widened to every target -> KILLED
carve-out removed (regression back) -> KILLED
carve-out checked BEFORE attestation -> KILLED
THE ORDERING MUTANT SURVIVED MY FIRST TEST. Both orderings return None, so
asserting the verdict could not tell them apart — the test asserted the claim
instead of the mechanism. Rewritten to observe that attestation is actually
consulted. Same defect class as the M21 test earlier in this branch: a
mutation surviving a test written specifically to kill it means the test is
measuring the wrong thing.
341 tests pass.
FOLLOW-UP (option 2, Ben's call, deliberately NOT done here): resolve the
handle before authorizing so BOTH layers apply. That needs a resolution
round-trip through the connector — new wire surface — so it belongs in its own
phase rather than bolted onto this one. Recorded in the code comment at the
carve-out, not just here.
* fix(relay): close two fail-open boundaries; test the code-only decline for real
Both blockers from review, each REPRODUCED before fixing.
1. STRUCTURED DECLINE HAD NO GUARD. Deleting `raw_response=result` from both
`_send_prompt` return branches left all 34 tests green — a surviving,
non-equivalent security mutant. The `code` field is the documented
PREFERRED signal precisely because a connector may send no prose, and a
caller rebuilding `{"success": False, "error": ...}` cannot see it.
Cause: every existing case declines with marker TEXT. The evidence for the
code-only path was a hand-built SimpleNamespace in a different file — a
stand-in for the adapter, so it verified my fixture instead of production.
Fixed with a CodeOnlyDecliningConnector driving the real
`send_exec_approval` -> `_send_prompt`, feeding the REAL SendResult to the
REAL `_approval_send_outcome`, plus the same shape on the media lane.
drop raw_response SURVIVED (34 passed) -> KILLED
2. TWO FAIL-OPEN BOUNDARIES, both "absence" and "fault" sharing a return.
`_relay_fronted` swallowed EVERY exception and returned an empty set, which
`relay_routed_platform` reads as "not relay-routed" — skipping the guard.
Probe, with a positive control in the same run:
positive_control_denied = True
discovery_fault_denied = False <- unattested target AUTHORIZED
`_authorize_relay_target` caught every exception during IMPORT as "no
gateway package". A module that exists and fails to initialize is a fault,
not an absence, and returning None there means authorized.
Now: ImportError alone is absence; anything else raises RelayRouteUnknown
and `authorize_relay_target` converts it to a REFUSAL STRING (not a raised
exception — every caller treats the return value as the verdict, so raising
would trade a fail-open for a crash).
Kept the converse under test so "fail closed" does not silently become
"refuse everything in CLI/cron", which is the outage the broad except
existed to prevent.
discovery fault -> empty set KILLED
RelayRouteUnknown -> authorized KILLED
import fault -> authorized KILLED
397 passed (was 392, +5 new cases), zero failures.
* fix(relay): close all seven review-round-3 blockers
Every finding reproduced before fixing; every fix mutation-checked after.
CONTENT LEAKS (the decline was laundered into a different op, same chat)
#1 A declined DRAFT SEAL replayed as a plain send. On stream-is-the-message
platforms the turn-final becomes draft(final=True); `_seal_open_draft`
dropped the structured body, so `_absorb_into_open_draft` read a REFUSAL as
a lane failure and fell through. Probe, Slack descriptor:
before: draft(partial) -> draft(final,SECRET) -> send(SECRET)
after: draft(partial) -> draft(final,SECRET)
My first probe of this used a discord descriptor and showed no seal at all —
the leak is real, my probe was wrong (streams only arm for Slack).
#6 Task-card PROGRESS had the same defect one lane over: a bare failed
SendResult reads as "card lane unavailable", and TurnRunner then sends the
task text to the same chat. Both card methods now carry raw_response and
the caller suppresses the fallback on a decline.
AUTHORIZATION BYPASSES
#2 `except ImportError` was NOT the fix I claimed last round. ImportError also
covers a broken dependency inside an INSTALLED gateway; review probed
`ImportError.name = "gateway.relay.dependency"` and got an authorized
verdict. Now only a name identifying the gateway relay module itself is
absence. An ImportError with NO name stays absence — refusing on a fault we
cannot attribute would trade an unidentifiable bug for a real CLI/cron
outage, and an existing test caught exactly that when I first got it wrong.
#3 `relay_routed_platform` lowercases the requested platform; `_relay_fronted`
returned configured names verbatim. A platform configured as "Discord"
missed the membership test, looked native, and skipped the guard:
'discord' => refused 'Discord' => ALLOWED 'DISCORD' => ALLOWED
An attestation bypass on a string comparison.
UNDELIVERABLE PROMPTS THAT HUNG
#4 `_clarify_send_disposition` handled `failed` and `ambiguous` but not
`declined`, so a REFUSED clarify card fell through to wait_for_response and
blocked until clarify_timeout — indefinitely when configured non-positive.
A decline is more definitive than a failure, not less.
#5 The exec-approval decline branch returned quietly, which suppressed the text
fallback (right) but left the CENTRAL approval entry pending (wrong) — the
dangerous command stayed blocked until the approval timeout. My comment
claimed the registration was torn down; only RelayAdapter's private map was.
It now raises `_ExecApprovalDeclined`, which propagates to
`_await_gateway_decision`'s existing notify-failure path (drops the entry,
unblocks the tool). A dedicated type, re-raised past the local
`except Exception` that would otherwise have restored the leak.
#7 THE GAP THAT LET ALL OF THIS SHIP. Both caller-level suppressions were
unfalsifiable: deleting either branch left 36/38 tests green. The suites
drove `_approval_send_outcome` and `RelayAdapter` but never the real
TurnRunner / busy-session callers, so nothing observed whether a text send
FOLLOWED a decline — which is the whole property.
tests/gateway/test_decline_fallback_suppression.py drives both real callers
and records every send. Each decline case is paired with an ordinary-FAILURE
control, because without one a caller that never falls back would also pass.
MUTATIONS (all on production source, anchors count-checked, restored after)
#1 seal decline -> plain send KILLED
#1b seal drops raw_response KILLED
#2 nested ImportError -> authorized KILLED
#3 fronted set not normalized KILLED
#4 clarify declined branch removed KILLED
#5 approval decline returns not raises KILLED
#6 task_card drops raw_response KILLED
#7 slash-confirm suppression removed KILLED
#7's two were the reviewer's SURVIVORS (36/38 passing); both now die.
425 passed, zero failures.
* fix(relay): close the three round-4 blockers
Round 4 confirmed six of seven round-3 fixes and found three more. Each
reproduced before fixing, each mutation-checked after.
1. A NAMELESS ImportError still authorized. Last round I admitted it as
"absence" to protect the CLI/cron path. That reasoning was WRONG and the
interpreter says so:
import gateway.relay.nope -> ModuleNotFoundError, name="gateway.relay.nope"
import totally_absent_pkg -> ModuleNotFoundError, name="totally_absent_pkg"
Genuine absence is ALWAYS ModuleNotFoundError with `.name` set, so the
CLI/cron path never produces a bare ImportError and nothing legitimate was
being protected. A plain or nameless ImportError comes from an import hook
or a module that failed while initializing — an unattributable FAULT.
Now: absence is ModuleNotFoundError naming gateway / gateway.relay /
gateway.relay.egress; everything else refuses. Two existing tests raised a
bare ImportError to simulate absence and were corrected to the real shape.
2. SESSION ATTESTATION INVENTED IDS. `_session_ids` split every id on the first
colon to recover "chat" from "chat:thread". Matrix ids contain a colon
natively, so `!room:server.org` attested a bare `!room` — the guard
vouching for a destination on its own fabrication. The split now applies
only to platforms whose ids genuinely carry a `:thread` suffix (allow-list;
unknown platforms are treated as un-splittable, which can only refuse more).
Kept a Slack control: dropping the split entirely would refuse legitimate
thread replies, which is the outage the split exists to prevent.
3. THE TASK-CARD FIX WAS UNFALSIFIABLE — my own round-3 mistake, and the same
one round 3 caught me making. I added the production branch AND a test, but
the test stopped at RelayAdapter: it proved `raw_response` is carried and
never called `TurnRunner._task_card_publish`, which owns the property.
Deleting the real branch left 30 tests green. Now driven through the real
caller, with an ordinary-failure control.
The lesson generalises: proving the DATA reaches the boundary is not proving
the CALLER acts on it. Every one of these decline fixes has two halves and
the second half is where the security lives.
Also closed the round-4 non-blocking finding: `gateway/relay/egress.py` has its
OWN import boundary, and the existing test intercepted the earlier import in
tools/send_message_tool.py, so it was never exercised. Mutating that classifier
to treat every ImportError as absence now dies.
MUTATIONS (production source, anchors count-checked, restored after)
R4-1 nameless ImportError -> authorized KILLED
R4-2 session split unconditional KILLED
R4-3 task-card caller branch removed KILLED (was SURVIVED)
egress classifier: any ImportError = absence KILLED
Also probed and found NOT a leak: a refused OPENING draft frame disarms the
stream and the turn-final goes out via `send`. That send is itself guarded and
the connector refuses it too, so no content is delivered — unlike the seal case
(round 3, #1) where the seal was the only check on that path.
452 passed, zero failures.
* fix(relay): recover the thread parent from thread_id, not a colon split
Round 4 blocker 2 was closed with an allow-list of platforms whose ids have no
native colon. Reviewing my own fix while round 5 ran, the allow-list is the
wrong mechanism: it NARROWS a guess instead of removing it, and it still gets
Matrix wrong the moment a Matrix session is thread-qualified
(`!room:server.org:$thr` -> split yields `!room`).
The structured field was there all along. `_session_entry_id` composes the id
as f"{chat_id}:{thread_id}" and the entry still carries `thread_id`
separately, so the parent is knowable EXACTLY: strip the known suffix, or add
nothing. No platform list, no guessing, correct for ids that contain colons.
Mutations:
back to splitting on the first colon KILLED
thread parent never recovered (over-refuse) KILLED
Both directions matter: the first invents attestations, the second refuses
legitimate thread replies.
One existing test (M25) asserted the right PROPERTY with a fixture that omitted
`thread_id` — a shape real entries never have. Fixture corrected, assertions
untouched.
453 passed.
* fix(relay): close the four round-5 blockers
Each reproduced before fixing, each mutation-checked after.
R5-1 A DISABLED NATIVE ADAPTER BYPASSED AUTHORIZATION. `_has_live_native_adapter`
treated any entry in the adapter map as native; `resolve_delivery_transport`
ignores a native adapter whose config is disabled and routes over Relay.
Two independent routing classifiers, disagreeing:
guard says native: True delivery routes relay: True
So the guard skipped authorization for a send that went over the relay.
The guard now applies the router's enabled-state rule; probed both
configurations and they agree.
R5-2 THREAD IDS WERE NEVER AUTHORIZED. The parser splits chat_id and thread_id;
only chat_id reached the guard. On Discord the thread IS the destination —
`POST /channels/{thread_id}/messages` — so an attested parent channel
authorized an arbitrary caller-supplied thread. `authorize_relay_target`
now takes thread_id and requires its own attestation (bare id or the
`chat:thread` form a session origin produces); both call sites forward it.
R5-3 A DECLINED **INITIAL** DRAFT WAS RETRIED AS A PLAIN SEND. Round 3 fixed the
declined SEAL; the declined OPEN was a different path. `send_draft`
returned a bare failure, so the stream consumer read "draft transport
unusable", disabled drafts and fell through to `_first_send`. Measured
through the real adapter and real StreamTransportMixin:
before: ops ['draft', 'send'] after: ops ['draft']
send_draft now carries raw_response; a decline is terminal for the run and
the guard sits in `_first_send`, where every fallback path converges.
R5-4 MY ROUND-4 TASK-CARD FIX SUPPRESSED EXACTLY ONE UPDATE. It set
`native_failed`, which the entry gate already uses for an ordinary broken
lane, so the next progress event skipped the decline branch and went
straight to the text fallback:
after first publish: [] after second: ['send']
Terminal declines are now a separate `egress_declined` state checked at the
entry gate. A refusal does not expire after one tick.
MUTATIONS
R5-1 disabled native counts as native KILLED
R5-2 thread_id not authorized KILLED
R5-2b tool does not forward thread_id KILLED (was SURVIVED)
R5-3 initial-draft decline not terminal KILLED
R5-3b _first_send guard removed KILLED
R5-4 declined state not persistent KILLED
R5-2b is the same gap that produced findings 3 and 4 of the last two rounds, a
third time: every test called `authorize_relay_target` directly, so dropping the
argument from the TOOL WRAPPER changed nothing. Testing the callee never proves
the caller uses it — now pinned explicitly.
Each fix ships with an ordinary-failure control, because every one of these
makes the guard refuse MORE, and over-refusal is now the larger risk.
474 passed, zero failures.
* refactor(relay): declare the terminal-decline state where it lives
Both terminal-decline flags were set dynamically. They worked (neither class is
frozen or slotted) but an undeclared attribute hides the state from anyone
reading the class, and this one is security-relevant.
_TaskCardState.egress_declined — declared dataclass field
StreamConsumer._egress_declined — initialised in __init__
Lifetime verified while checking whether a refusal can leak ACROSS turns and
mute a healthy destination: it cannot. _TaskCardState is constructed per
progress-drain (run_turn_runner.py:420) and the consumer's flags per run
(stream_consumer.py:163), so both are fresh each turn.
Also verified the guard's blast radius after adding thread authorization: the
ONLY callers of authorize_relay_target are the two model-facing send_message
call sites. Gateway-internal sends — notably the handoff path, which creates a
thread and immediately posts to it with no session provenance yet — go through
transport.adapter directly and are unaffected. That was the most plausible
over-refusal, and it does not reach this guard.
461 passed.
* fix(relay): close the four round-6 blockers — the edit lane
R6-1 MY OWN R5-1 FIX REINTRODUCED THE BYPASS IT CLOSED. I wrote
`except Exception: return True` around the config lookup, so a config read
fault declared the platform native while the ROUTER, reading the real
config, sends over the relay:
guard_has_live_native True guard_verdict None router relay
Routing we cannot determine is UNKNOWN. It now raises RelayRouteUnknown,
which the outer handler must re-raise rather than flatten to False, and
`authorize_relay_target` turns into a refusal. This is the second time a
convenience `except` in this function created a bypass; there is now no
permissive return left in it.
R6-2/3/4 THE NINTH LANE: `edit`. ONE dropped field, THREE leaks.
`RelayAdapter.edit_message` discarded the connector response, and three
independent callers read a bare edit failure as "editing is unavailable"
and re-send the content as a NEW message to the same chat:
stream edit fallback ['edit', 'edit', 'send'] the unseen tail
queued reconciliation ['edit', 'send'] the WHOLE response
task-card fallback ['edit', 'send'] the task text again
Fixed at the source (edit_message carries raw_response) plus each caller:
`_on_edit_failure` — the single funnel for stream edit failures — makes a
decline terminal for the run, `_send_fallback_final` refuses to deliver a
continuation after one, the queued reconciler returns instead of sending,
and the task-card fallback sets the same terminal state R5-4 introduced.
R5-4 fixed the native task-card op and I did not check its sibling
fallback path. The pattern across rounds 3-6 is consistent: the fix goes
where the decline is OBSERVED, and the leak lives wherever someone else
later decides to retry.
MUTATIONS
R6-1 config fault -> assume native KILLED
R6-1b RelayRouteUnknown swallowed as False KILLED
R6-2 edit drops raw_response KILLED
R6-2b edit-failure decline not terminal KILLED
R6-3 queued reconcile falls back on decline KILLED
R6-4 task-card fallback edit decline KILLED
Each with an ordinary-failure control: a genuinely un-editable message must
still be delivered, and a broken card lane must still reach the user.
481 passed, zero failures.
* fix(relay): add a terminal-decline latch at the adapter choke point
THE STRUCTURAL FIX, not a twelfth local check.
Rounds 3-6 of review found ONE defect in eleven lanes: the connector refuses an
op, and some caller downstream reads that as 'this lane is unavailable' and
retries the same content through a DIFFERENT op against the SAME chat. Media,
prompt, draft-open, draft-seal, native task card, task-card fallback edit,
slash-confirm, exec-approval, clarify, stream edit, queued reconciliation.
Each was closed by adding a check at one more call site. That approach cannot
converge: gateway/ has ~60 outbound call sites, every one of them a place a
future change can reintroduce this, and four consecutive review rounds each
found another. The reviewer's own count of lanes is the argument against the
per-site design.
Every relay frame from every one of those callers passes through
_transport.send_outbound. One latch there covers them all: once the connector
refuses a chat, this adapter stops emitting CONTENT frames for that chat.
Proven to subsume the local checks: with the stream-edit per-site check
DISABLED, the leak probe still reports blocked=true — the frame never reaches
the wire. The local checks stay as defence in depth and for their better error
messages, but they are no longer the only thing standing between a decline and
a re-addressed send.
Scope is deliberately narrow, and each limit is mutation-pinned:
per CHAT - a refusal must not mute other conversations
CONTENT ops - typing/delete carry nothing; latching them would leave a
stuck typing indicator for no security gain
self-healing - cleared when the connector accepts that chat again, so a
transient policy change does not need a restart
Mutations:
latch never set KILLED
latch never consulted KILLED
latch is global, not per-chat KILLED
latch never clears KILLED
485 passed.
* fix(relay): one route source; the latch already covered round 7's lanes
Round 7 reviewed 573e41e294 — one commit BEFORE the terminal-decline latch —
and independently reached the same conclusion I had: 'The per-call-site
approach is structurally wrong. Use one turn-scoped choke point.' That is the
latch in 6dbc004594.
Its four 'still broken' lanes (tool-progress edit, progress-overflow edit,
long-running heartbeat edit, stale streamed-final reconciliation) all share the
shape edit_message->declined->adapter.send(same chat, same content), and NONE
has a local check. Probed all four against the latch:
tool_progress ops ['edit'] blocked
progress_overflow ops ['edit'] blocked
heartbeat ops ['edit'] blocked
stale_final ops ['edit'] blocked
That is the argument for the choke point, measured: lanes nobody patched are
safe anyway. Pinned by a parametrized test named for those four lanes.
R7-1 IS A REAL BYPASS THE LATCH DOES NOT COVER, and it is fixed here. The guard
rebuilt routing from GATEWAY_RELAY_PLATFORMS while resolve_delivery_transport
asks the CONNECTED adapter (fronts_platform, from the handshake identity set).
Different snapshots: with env discovery stale or momentarily empty, the guard
said 'native' and the router sent over the relay, skipping authorization.
before: guard_relay_routed False / delivery relay
after: guard_relay_routed True / delivery relay / unattested target refused
The guard now asks the live adapter first and falls back to config only when
there is no runner (CLI/cron) — pinned in both directions.
R7-5 (non-blocking, and a fair hit): my stream-fallback test asserted
_egress_declined and never drove _send_fallback_final, so removing that early
return SURVIVED. The test now calls the real fallback and asserts the wire is
untouched; the mutation dies.
Mutations:
R7-1 guard ignores the live adapter KILLED (was SURVIVED)
R7-5 fallback early return removed KILLED (was SURVIVED)
latch not consulted KILLED
491 passed.
* fix(relay): close three holes found by attacking my own latch
Round 8's brief told the reviewer to attack the latch. I did the same in
parallel and found three real holes in it before the review returned.
1. send_for_platform BYPASSED THE LATCH ENTIRELY. It builds and posts its frame
directly rather than through _outbound — and it is the delivery resolver's
OWN entry point, so it is the single most important caller.
before: ops ['edit', 'send'] after: ops ['edit']
gateway/AGENTS.md states the rule I had just broken: 'Seal-interception
exists at BOTH egress doors (send() and send_for_platform()); a new egress
door needs the same two checks.' The latch is a third such check and I had
wired it to one door.
2. A COSMETIC SUCCESS CLEARED THE LATCH. Clearing on ANY success meant a
typing indicator — routinely allowed for a chat whose content is refused —
re-opened the door for the very next send:
ops ['edit', 'typing', 'send']
Only a CONTENT op the connector accepted may clear it now.
3. A THREAD INSIDE A REFUSED CHAT WAS NOT COVERED. A thread lives inside its
parent, so the same content reached the same conversation one level down:
ops ['edit', 'send']
The latch key now strips the thread suffix.
Also normalised int/str chat ids (callers pass both; a type mismatch would
silently unlatch).
MUTATIONS
send_for_platform not latched KILLED
cosmetic success clears the latch KILLED
thread suffix not stripped KILLED
draft-seal retry not latched SURVIVED — EQUIVALENT, proven:
is unreachable while latched (a declined edit before the seal
produces ZERO seal frames, measured). Kept as defence in depth because it
posts directly, and documented at the site rather than covered by a
test that could not fail.

* fix(relay): Telegram handle exemption + a turn boundary for the latch
Round 8 blockers. Two of its four were already closed by 93750e351a (it
reviewed the commit before it); these two are real and both are mine.
B1 — THE TELEGRAM @HANDLE EXEMPTION COVERED A NATIVE SEND.
_is_unresolved_handle exempts telegram @handles from attestation because
"the connector resolves and authorizes it". That justification is FALSE
whenever the gateway holds its own token: _send_to_platform calls
_send_telegram(pconfig.token, ...) directly and no connector is involved.
So an unattested @handle went out under the gateway's own credential
while the numeric control was correctly refused.
The exemption now requires that no native credential exists. A probe
fault WITHDRAWS the exemption (falls back to the ordinary attestation
check) rather than granting it.
Shipped with the converse control: relay-only config still exempts
@handles, and numeric targets stay guarded in both modes.
B4 — THE LATCH HAD NO BOUNDARY, SO IT WAS AN OUTAGE MECHANISM.
My own regression, and worse than reported. Removing "clear on cosmetic
success" (correctly) removed the ONLY way the latch could ever clear: a
content op can never reach the connector to succeed, because the latch
blocks it locally first. A refusal at 09:00 muted that chat forever.
A new inbound message for a chat is the generation marker — the natural
teardown point. Suppression still holds for the whole turn.
same_turn_blocked: true next_turn_delivered: true
MUTATIONS (all killed)
handle exemption ignores native credential
native-credential fault GRANTS the exemption
no turn boundary (latch never clears)
teardown clears ALL chats not just this one
teardown ignores the chat
The last two SURVIVED first: I tested _clear_declined_for_turn directly
and never proved _on_inbound calls it — the caller-level gap that has now
produced four blockers on this branch. Added a test driving the real
inbound entry point.
One self-inflicted bug, caught by my own fault test: the probe imported
load_config, which does not exist (it is load_gateway_config), so it
always threw and returned the fault default. The test that pinned fault
behaviour is what exposed it.
510 passed.
* fix(relay): correct latch identity and boundary; one config snapshot
Round 9, four blockers, all reproduced.
B1+B4 — THE TEARDOWN WAS AT THE WRONG PLACE, twice over.
It sat on the adapter's raw _on_inbound, which runs BEFORE profile
routing, the ignored-channel guard, plugin hooks and user authorization.
An unauthorized or dropped event could therefore clear a refusal
belonging to an active turn, and stale content then went out as a
different op. The same placement missed Discord interaction passthrough,
which builds its own MessageEvent and calls handle_message directly, so
slash commands and modal submits stayed muted after an earlier decline.
Both are one mistake: I picked a lane instead of a boundary. Teardown now
runs immediately after _hm_admit_event, the single admission gate every
entry path shares.
dropped event -> latch survives, stale send blocked
admitted event -> latch clears
B2 — THE LATCH KEY SPLIT ON ':', WHICH IS A MISTAKE I ALREADY FIXED ONCE.
_latch_key did str(chat_id).split(":", 1)[0], so !room:tenant-a and
!room:tenant-b both keyed !room: a decline in one Matrix room muted
another, and inbound from one cleared the other's refusal. egress.py
::_session_ids stopped doing exactly this in round 4 and I reintroduced
it three rounds later.
Parent identity is never recoverable from identifier TEXT. Thread
coverage is now structural: _thread_parent looks the relationship up in
the recorded auto-thread map.
B3 — AUTHORIZATION AND DISPATCH USED DIFFERENT CONFIG SNAPSHOTS.
_handle_send retains one pconfig; the guard independently reloaded
config. Across a transition the authorization snapshot could see a
connector-only setup (exemption granted) while dispatch still held the
native token and sent the unattested @handle itself. The guard now takes
native_token from the SAME snapshot dispatch will use. A caller that
omits it does not silently look like "no token".
NB-1/2/3 also closed: real-object snapshot tests, an exception shield
that faces a real exception, and send_follow_up no longer discards the
connector's verdict (that discard is exactly how the edit lane laundered
declines).
MUTATIONS (all killed)
latch key splits on colon again
thread parent lookup disabled
dispatch token ignored by guard
tool drops the snapshot token
admission teardown removed
teardown moved BEFORE admission
exception shield removed
follow_up drops raw_response
"admission teardown removed" SURVIVED first: I had tested the helper, not
_handle_message. Added a test driving production _handle_message with
admission stubbed both ways. Fifth caller-level gap on this branch.
One self-inflicted bug caught before commit: I passed pconfig.token in
_handle_react, which has no pconfig — a NameError on every reaction.
516 passed.
* docs(relay): pin the latch's thread coverage limit as a deliberate trade
_thread_parent only sees connector auto-threads, and that map is capped at
256 entries, so a user-created or evicted thread does not inherit its
parent's latch. Documented at the site and asserted by a test, because the
alternative - deriving parents from identifier text - is exactly what muted
unrelated Matrix rooms in round 9.
The primary control is unaffected: authorize_relay_target takes thread_id as
part of the destination and attests it on every send (6 thread tests).
* refactor(relay): one SendResult decline classifier for all 8 gateway lanes
The extraction found a DEFECT, not just repetition.
Eight gateway lanes each hand-rolled the unwrapping of a decline from a
SendResult, and they did not agree. Six checked only raw_response. Two
also checked the error text. A connector that answers with the uniform
decline SENTENCE and no structured code - the documented contract for
older connectors, per _approval_send_outcome - was therefore classified
as an ordinary failure by those six lanes, so each treated a refusal as
"editing unavailable" and retried through another op.
Measured:
text-only decline six-site check False two-site check True
structured decline six-site check True two-site check True
No content leaked, because the adapter latch classifies the transport
dict directly and catches both shapes (verified: text-only decline still
latches C1 and keeps SECRET off the wire). The cost was wrong verdicts
and futile retries, not disclosure.
declined_send(result) in gateway/relay/egress.py now owns this. It checks
raw_response when structured, else the error text, and preserves the
ambiguous exclusion - an ambiguous result is a transport outcome, so it
must never read as a refusal.
run.py keeps its own shape deliberately: that lane has three verdicts
(ambiguous / declined / failed), so it checks ambiguous first and then
delegates the boolean.
MUTATIONS (all killed)
helper drops the text-only branch
helper drops the structured branch
ambiguous no longer excluded
draft lane decline check removed
edit-failure lane decline check removed
prompt verdict lane check removed
slash-confirm lane check removed
draft lane goes terminal on ANY failure (over-refusal direction)
"draft lane decline check removed" SURVIVED first: _send_draft_frame had
no test driving an unsuccessful send_draft at all. Added one, with an
ordinary-failure control so the fix cannot silently become "one flaky
frame mutes the chat". A non-unique anchor also masked the edit-failure
lane on the first pass - the trap my own skill warns about.
This closes the duplication that caused four of nine rounds of blockers:
a new lane now calls one classifier instead of copying three lines.
519 passed.
* fix(relay): latch identity, new-turn boundary, seal arming, ambiguity
Round 10, four blockers, each reproduced before fixing. Two are my own
regressions from the previous two rounds.
B1 - ADMISSION IS NOT A NEW-TURN BOUNDARY.
Round 9 moved teardown to just after _hm_admit_event. That is only an
ADMISSION gate: an authorized message can be steered into a running
session, answer a pending prompt, run a busy slash command, or be refused
by the pause/drain gates - all without starting a turn. Each of those
cleared the ACTIVE turn's refusal, and a later fallback from that turn
reached the wire (probe: latch emptied, wire ops ['edit', 'send']).
Teardown now runs after _claim_active_session_slot, the first point the
runner OWNS a new turn. The new test drives production _handle_message
through all four non-turn lanes plus the real new-turn path.
B2 - LATCH IDENTITY OMITTED THE LOGICAL PLATFORM.
One relay adapter fronts several platforms, so native ids collide. A
Discord refusal for chat 42 was cleared by clear_egress_latch("telegram",
"42") - the method took a platform and ignored it - and the Discord
fallback then reached the connector. Keyed by normalized platform plus
exact chat id; thread-parent expansion keeps the platform component.
B3 - THE DIRECT DRAFT-SEAL PATH DID NOT ARM THE LATCH.
_seal_open_draft posts through _attempt directly rather than _outbound,
so a definite decline logged and returned but never latched. The
immediate plain-send fallback was suppressed by the caller's own check;
later same-turn sends were not (wire ['draft', 'draft', 'send'], the
third frame carrying refused content).
B4 - MY OWN REFACTOR MADE AMBIGUOUS RESULTS TERMINAL.
send_draft's ambiguous projection discarded raw_response, so
declined_send fell through to the error-text branch - and an ambiguous
result whose text carries the decline marker ("... egress declined: ack
lost") read as a DEFINITE refusal and terminated the run. Ambiguous means
the frame may well have been delivered: a transport outcome, never an
authorization one.
Fixed on both layers: the projection carries the body (and the seal's
ambiguous return is now explicit too), and declined_send's text-only
branch - which cannot see the ambiguous flag - treats ack-lost text as
transport ambiguity. Audited every SendResult projection in adapter.py
for the same shape.
MUTATIONS (all killed)
latch key drops the platform
clear_egress_latch ignores platform
draft seal does not arm the latch
ambiguous projection drops raw body
declined_send infers decline from ack-lost text
teardown back at admission
523 passed.
* refactor(relay): split the terminal-decline latch out of the guard PR
The latch moves to feat/p5-egress-decline-latch (pushed at 3cf45736d7,
which retains the full history) for redesign. This PR keeps the
authorization guard and the per-site decline checks.
WHY. Across eleven review rounds the two halves behaved very differently.
The guard is a PURE FUNCTION of the destination - its blockers were all
"you asked the wrong question" (case sensitivity, nested ImportError,
missing thread_id, config snapshot skew), each a one-line correction that
then stayed fixed. Rounds 7-10 found nothing new in it.
The latch is MUTABLE STATE WITH A LIFETIME living on RelayAdapter - an
object registered once per process that holds the WebSocket and has no
concept of a turn. Nine of its blockers reduce to three questions the
adapter cannot answer: when does it end, who arms it, what is it keyed
on. Every answer so far has been a proxy (a successful op, an inbound
message, an admitted event, a claimed session slot) and every proxy was
wrong in a lane found later.
The per-site checks hold identical information on `st` - a PER-TURN
object - and have produced zero blockers, because the state dies with the
turn and nobody has to decide when it ends.
The no-relaunder property does NOT depend on the latch. Measured on the
real consumer path with the latch absent: a declined draft frame sets
_egress_declined and puts nothing on the wire.
Removal verified structurally rather than by eye: an AST diff of every
symbol between HEAD and this tree reports only latch symbols gone,
nothing added. That check caught two over-deletions my strip made -
_on_inbound (consumed by a "next def" boundary) and _SEEN_INBOUND_MAX
(a class constant inside the removed span). Both restored; 19 failures
went to 0.
ALSO: RESTORED A TEST I WRONGLY REPORTED AS PASSING.
test_tool_guard_forwards_thread_id never made it into the repo - `git log
-S` finds it in no commit - though round 5 recorded its mutant as killed.
Dropping thread_id from the guard call therefore survived the entire
tests/tools suite (146 passed). Written properly this time, driving the
real _handle_send far enough to reach the guard. It now KILLS that
mutant.
MUTATIONS on this tree
guard fault authorizes instead of refusing KILLED
thread_id dropped from the guard call KILLED (was SURVIVED)
handle exemption ignores native credential KILLED
draft lane decline check removed KILLED
prompt verdict lane check removed KILLED
slash-confirm lane check removed KILLED
503 passed.
* test(relay): close the phantom-coverage gaps the guard audit found
The thread_id test that was reported as killing a round-5 mutant turned
out never to have been committed. That is a reason to distrust the other
claimed kills, so I re-ran every guard mutation against the COMMITTED
tree instead of trusting the earlier reports.
Result: 9 of 11 killed, and the two "SKIPPED" ones had non-unique
anchors hiding SIX separate sites. Mutating those individually found
three real survivors.
CASE NORMALISATION (round 3, finding 3) WAS HALF-COVERED.
test_relay_fronted_matching_is_case_insensitive varies the CONFIGURED
name but always requests lowercase "discord", so it pins _relay_fronted's
normalisation and nothing else. The REQUESTED name's `.lower()` was
covered by nothing at all. Probe with it removed:
relay_routed("Discord") -> False
authorize("Discord", unattested) -> AUTHORIZED
which is exactly the bypass round 3 reported, alive again and untested.
Two further sites were untested in the OVER-REFUSAL direction: the
attested store is keyed lowercase, so a mixed-case request missed its own
attested set and refused legitimate traffic. attested_relay_targets' own
normalisation was invisible to every existing test because they all
monkeypatch that function away; it is now asserted against the real
function with only its leaf sources stubbed.
Three tests added. All six case sites now die when mutated.
I also re-did the three fail-closed RelayRouteUnknown mutations properly.
The first pass swapped whole lines and produced IndentationErrors, so
"KILLED" there proved nothing but a syntax error. Neutralising each raise
at correct indentation: all three genuinely KILLED.
FINAL AUDIT ON THIS TREE — 17 mutations, zero survivors
guard: thread_id dropped at the call site
guard: react path unguarded
guard: handle exemption ignores native credential
guard: 3x fail-closed raise neutralised
guard: 6x case-normalisation site
classifier: ambiguous treated as a decline
classifier: text-only decline branch removed
lane: draft / stream-edit / prompt / slash-confirm checks removed
511 passed.
* test(relay): make the stream-edit test fail for the right reason
Review of 45835a282d raised one blocking issue and three non-blocking
ones. All four are addressed; none was a production defect.
BLOCKING — the stream-edit test failed on the double, not on a leak.
test_declined_stream_edit_does_not_send_the_unseen_tail implemented only
the GUARDED path in its consumer double. Removing either guard therefore
raised AttributeError inside the fake before any send could be observed:
guard 1 removed -> AttributeError: no attribute '_is_flood_error'
guard 2 removed -> AttributeError: no attribute '_clean_for_display'
Red, but for the wrong reason — the test could not have caught the leak
it is named for. My own docstring claimed it drove the fallback and
checked the wire; it did neither.
The double now implements everything the UNGUARDED path reaches
(_is_flood_error, _flood_strikes, _current_edit_interval, _last_edit_time,
_notify_new_message, _try_strip_cursor, _clean_for_display,
_fallback_prefix, _metadata_for_send). Both mutations now fail on real
assertions:
guard 1 removed -> assert consumer._egress_declined is True
guard 2 removed -> AssertionError: the unseen tail reached the wire:
['send']
NON-BLOCKING 1 — a docstring claimed more than the test exercises.
test_requested_platform_name_is_also_normalised described a mixed-case
send_message(target="Discord:999") bypass. That entry point cannot reach
it: _resolve_tool_target lowercases the platform at
tools/send_message_tool.py:47 before the guard runs. The test still pins
a real contract — the helpers must not assume a lowercased argument, for
the gateway lanes and any future non-normalising caller — so the claim is
narrowed to that rather than the test removed.
NON-BLOCKING 2 — the module docstring said "every lane drives the REAL
RelayAdapter". The stream tests drive mixin doubles by design, because
the behaviour under test belongs to the adapter's CALLER. Docstring now
distinguishes the two kinds.
NON-BLOCKING 3 — latch-deletion residue in gateway/relay/adapter.py:418:
return None
return latched if surface_declines else None
The second line was unreachable and referenced a name deleted with the
latch. Removed, along with the 20-line comment block describing the latch
as "the structural fix" — that mechanism now lives on
feat/p5-egress-decline-latch, not here.
The reviewer independently confirmed the large deletion: an AST census
between 3cf45736d7 and f57a2298fa reports only latch symbols removed and
nothing added.
511 passed.
* docs(relay): correct three claims that outran the code
Review of 41ce3cc765 found no new production defect but three overstated
claims, one of them in my own commit message.
1. THE LATCH COMMENTARY WAS STILL THERE. My previous commit message said
it removed "the 20-line comment block describing the latch as the
structural fix". It removed only the unreachable statement. Twenty
lines at adapter.py:361-380 still described a per-chat latch, a choke
point and its scope rules - none of which exist on this branch. In a
refusal-sensitive module that reads as coverage this branch does not
have. Now removed for real.
This is the same defect class as the tests: a claim that outran what
the code does. I made it while fixing that class.
2. THE STREAM-TEST DOCSTRING OVERSTATED BOTH MUTANTS. It said the
mutation "now fails on the assertion that a send reached the wire" -
true of one guard, not both. Verified separately:
remove the _on_edit_failure check -> dies on _egress_declined,
never reaches the fallback
remove the fallback early return -> dies on the wire: ['send']
Both are valid behavioural failures, which is what the blocker asked
for; they are different observables and the docstring now says so.
3. Duplicate `from types import SimpleNamespace` from an earlier scripted
insert; imports reordered.
112 tests pass in the four focused files.
* fix(relay): close two authorization defects found in review
Both were reproduced before fixing and both mutants are pinned.
1. A LIVE relay adapter whose fronts_platform() raised degraded into the
config fallback. `_live_relay_fronted` returned None for every failure,
and None means "no live adapter, use the config snapshot" — so a faulting
adapter plus an empty/stale snapshot made the guard conclude "not
relay-routed" and authorize an unattested destination, while
resolve_delivery_transport asks that same adapter and still routes over
the relay. Measured: relay_routed=False, verdict None for chat 999.
Absence and fault now have separate return values: None only when there
is no runner or no relay adapter; a live adapter that cannot answer
raises RelayRouteUnknown. This is the third instance of this bug class in
this file, and the first two were also mine.
2. An attested chat whose id equalled the requested THREAD id vouched for
that thread. The `thread in attested` arm proved nothing about parentage.
Measured: attested {"-100A", "7"} authorized (-100A, thread 7).
Only the bound `parent:thread` form is accepted now. Nothing legitimate
needed the bare arm — _session_entry_id records a threaded origin as
f"{chat_id}:{thread_id}", and a thread addressed as its own channel
arrives as chat_id and passes the parent check.
The existing test blessed the bare form via parametrize, so it PINNED the
defect. Corrected, plus negative controls for the sibling-chat and
other-parent cases and a positive control proving genuine absence still
takes the config path (otherwise fix 1 would break native-only deploys).
Merged origin/main (was 22 behind). 428 passed via scripts/run_tests.sh;
full 10-row mutation ledger re-killed on the merged tree, none dying on an
exception rather than an assertion.
* fix(relay): only a missing adapter is absence; everything else is a fault
Reviewer BLOCKER, reproduced before fixing. Two more paths where a PRESENT
relay adapter still degraded into the config snapshot:
1. `fronts_platform` may be a property or descriptor, so the ATTRIBUTE
LOOKUP can raise — and the lookup sat inside the absence handler. Probed
with a raising property plus an empty snapshot: live=None, routed=False,
verdict=None, i.e. an unattested target authorized. The previous test made
an already-retrieved METHOD raise, so it could not reach this.
2. A present adapter with no usable `fronts_platform` returned None for the
same reason. An adapter that cannot say what it fronts is broken, not
absent, so it now raises too.
Also found by my own spot-check while the review ran: the nested imports of
`gateway.config` / `gateway.run` inside the live probe shared the broad
handler, so a broken installation degraded to the snapshot as well. Probed
with a healthy-adapter positive control in the same run — healthy refused
the unattested target, faulted authorized it. `_relay_fronted` one function
below already drew this exact distinction for its own import.
The boundary is now: `relay is None` is the ONLY absence. Everything about a
present adapter — attribute access, callability, the call itself, and the
imports needed to reach it — is a fault and raises RelayRouteUnknown.
This is the fourth variant of absence-vs-fault in this file and all four
were mine. The lesson is in the code as a comment rather than in a commit
message nobody re-reads.
Four controls keep genuine absence benign: no runner, no relay adapter in
the runner, a real ModuleNotFoundError naming the gateway package, and the
configured-attested-target-still-sends case.
434 passed via scripts/run_tests.sh; 9-row mutation ledger re-killed
including both new guards, none dying on an exception.
* fix(relay): invert the live probe to fail closed by default
Reviewer BLOCKER round 2, reproduced: reading the adapter registry can also
raise. A runner whose `adapters.get()` raised gave relay_present=True,
live=None, routed=False, verdict=None — unattested discord:999 authorized.
That was the FIFTH boundary in one function with the same defect: the call,
the attribute lookup, a non-callable attribute, the nested imports, and now
the registry lookup. Each round I patched the reported boundary and the
defect moved one statement up. The cause was the shape, not the statements:
the function asked "did something go wrong?" and answered None, and None
MEANS "no live adapter, use the config snapshot" — so every statement was a
new chance to fail open, and every new statement would have been too.
Inverted rather than patched a sixth time. Each `return None` now sits
behind an explicit narrow check that cannot itself be the fault (no runner,
no adapters, no relay key, gateway package genuinely absent), and one outer
handler turns anything else into RelayRouteUnknown. A statement added inside
this function is now fail-CLOSED by default.
Verified all six fault shapes raise (call, attribute, missing method,
registry .get, .adapters property, runner ref) and all five absence shapes
stay benign, plus a liveness control where the config snapshot disagrees
with a healthy adapter and the adapter still wins.
Four new tests, including the two absence controls that keep native-only and
CLI deployments working. 438 passed via scripts/run_tests.sh. Mutation
ledger: 8 killed. One survivor recorded as a proven equivalent mutant —
widening `if not registry` to `or {}` is behaviourally identical because
`{}.get()` returns None, i.e. the same absence; it is a readability guard.

compat(plugins): warn once per name when a plugin resolves an old import path; lint step restored in CI
Every PLUGIN-COMPAT __getattr__ now calls hermes_cli.plugin_compat.warn_once(facade, name, target) before
resolving, emitting a HermesPluginCompatWarning (FutureWarning) once per process per name: old path, new
path, removal target. Importing a facade for its live API stays silent; only resolving a moved name warns.
COMPAT_MANIFEST.md documents the warning and how to silence it during migration.
Verified the runtime never routes through a pointer: every entry point (run_agent, cli, hermes_cli.main,
gateway.run, tui_gateway.server, web_server, model_tools + tool discovery, hermes_state, cron.scheduler,
browser_tool, mcp_tool, kanban, auth) imports clean and `hermes doctor` runs end to end with the warning

compat(plugins): temporary import-path shims for external plugins — ONE commit, revert on schedule
The Sep 2026 decomposition (PR #102117) makes internal import paths a non-API: names now live in the focused modules that define them. This commit is the ONLY thing keeping the old paths alive, so external plugins have time to update. It is deliberately a single, unsquashed commit: git revert <this sha> removes every shim, stub and manifest at once on the announced date. Nothing in-tree may depend on these pointers: scripts/check_compat_pointers.py (wired into lint.yml) fails CI if it does. What it adds (see COMPAT_MANIFEST.md, compat_manifest.json): - 332 facade modules get one delimited `PLUGIN-COMPAT` block appended at the end of the file - 1,172 moved names resolved lazily via a module `__getattr__` (PEP 562) — never a top-level import, so no import cycles; facades that already had `__getattr__` get a chained one - 592 third-party/stdlib names the old modules used to expose, with their original import statements - 266 public definitions that had been deleted as unused, restored byte-for-byte from the pre-decomposition tree (+40 private helpers and 16 imports pulled in only because a restored definition needs them) - 3 deleted modules recreated as re-export stubs (gateway/startup_watchdog, hermes_cli/observability/ relay_runtime, tools/environments/modal_utils) - private names (`_x`) get no pointer: they were never API (3,792 skipped) Verified: all 335 touched modules import under a fresh HERMES_HOME and every manifest name resolves; the lint reports zero in-tree uses; ruff clean; targeted suites unchanged. |

fix(gateway): keep one Telegram bubble when the finalize edit fails under reply_to_mode=first (#71047)
Problem B of #71047: with streaming + reply_to_mode='first', the streamed
preview is a reply-quote of the user's message. When the turn-final edit
hits flood control, the empty-tail fresh-commit resend either (a) also got
flood-capped -> the consumer reported 'failed', the gateway's normal final
send fired, and the never-deleted preview + the fresh final left TWO
visible bubbles, or (b) succeeded but as a plain non-reply message that
didn't match the preview's anchor.
- preserve the turn's reply anchor (initial_reply_to_id) on the
empty-fallback fresh-commit resend so the replacement message quotes the
user's message exactly like the preview and the non-streaming path
- retry a flood-rejected preview deleteMessage once (delete_message
returns False rather than raising) so the stale preview doesn't linger
next to the fresh final; still best-effort, and the preview is only ever
deleted AFTER the replacement send succeeded
- regression tests for the anchor, the delete retry, and the
flood-capped-resend single-bubble suppression decision
Builds on @fangliquanflq's PR #96097 ('preview' verdict for flood-rejected
fresh commits), cherry-picked as the previous commit with the conflict

fix(gateway): judge delivery success against final content, not flag trust (#95382, #98552)
A record-less delivery flag (final_response_sent / final_content_delivered set with no recorded turn-final payload) was trusted blindly by delivered_final_matches (None -> legacy trust), so a first-edit prefix or a truncated finalize suppressed the gateway's corrective send — silent partial delivery. - delivered_final_matches: record-less flags are now reconciled against the FINAL content via has_delivered_text; only the explicitly-marked ambiguous-timeout path (_delivery_ambiguous) keeps legacy trust. - _try_fresh_final and the native-streaming optimistic finalize now record their delivered payload (the last record-less flag setters); the optimistic record rolls back on definitive dispatch failure. - Discord adapter: dead-transport send failures (client gone, WS closed/reset) are classified as send_path_degraded (retryable) so the delivery-obligation ledger's reconnect sweep replays the stranded final response instead of losing it until a process restart. Fixes #95382; closes the #98552 false-positive class. |

fix(relay): resolve fresh-final unfurl decision per chat, not per primary identity (#99206)
The stream consumer called prefers_fresh_final_streaming(text, metadata=...) only, and no metadata producer stamps a platform key — so RelayAdapter's hook always fell back to the PRIMARY descriptor's platform (the scalar-vs-per-chat capability seam, third occurrence). Two failure directions on multiplexed relays with platforms.relay.extra.slack.unfurl_links/media: true (#97957): - Slack primary fronting Telegram/Discord: every link-bearing streamed final on the non-Slack chats finalized as a fresh send with no delete op advertised -> the answer delivered TWICE (orphaned preview). - Non-Slack primary fronting Slack: the hook returned False, leaving the force-on unfurl feature dark on exactly the chats it shipped for. Pass chat_id=self.chat_id from the consumer; the relay hook already accepted it and resolves via _platform_by_chat + the per-platform negotiated descriptor. Graduated TypeError fallback keeps the single-platform hook signatures (Telegram, base class) and legacy test doubles working unchanged. Both regression tests verified RED against the unfixed consumer, GREEN with the fix; single-platform relays are unaffected (#97957's own 30 tests unchanged-green). |

fix(wecom): eliminate duplicate + split bubbles in native streaming
Fixes two related native-streaming bubble defects surfaced in production:
1. Duplicate bubble on long turns — when keep-alive already refreshed the
6-min reply window, the Layer-2 clock fallback still declined the finalize
frame and forced a proactive send(), duplicating the message. Skip the
clock fallback while keep-alive is active; intermediate-frame failures are
now fully fire-and-forget (only a failed FINAL frame falls back to send()).
2. Split / mini bubbles ('Cla' + 'ude ...') — two compounding root causes:
a) In native streaming a mid-turn commentary (e.g. a Hindsight recall
notice) called _reset_segment_state(), clearing the cumulative
_accumulated so the next delta + finalize frame carried only the few
chars accumulated after the reset. Native streaming now skips that
reset (commentary still posts as its own message via send()).
b) The adapter-side _BlockChunker.update() 'only grow' guard silently
dropped any cumulative snapshot shorter than its high-water mark, so
after a baseline reset the leading characters were stranded before
_emitted_len. Removed the _BlockChunker sentence-alignment + idle-flush
layer entirely; intermediate frames are pure identity-dedup, matching
the fire-and-forget model.
Also removes ~232 lines of now-dead code (_BlockChunker class, idle-flush
machinery, block-stream constants) and aligns the test suite with the
fire-and-forget frame model, including a regression test that locks the
native-commentary-no-reset behavior.
Tests: 177 passed, 3 skipped (wecom + stream_consumer suites).

feat(wecom): native reply streaming (per-turn isolation, dedup-safe delivery, interaction boundaries)
Implement native reply streaming for the WeCom (企业微信) adapter over the long-connection "msgtype: stream" transport, so a reply renders as a single live-updating typing bubble instead of one final block. Aligns with the official wecom-openclaw-plugin streaming behavior. Includes the machinery intrinsic to native streaming on WeCom: - Transport: seed frame (<think></think>) opens the typing bubble, intermediate frames update it, a finalize frame closes it; native-streaming adapters are let past the edit-only gate. Fire-and-forget intermediate frames (WeCom long-connection mode has no documented edit-rate limit); an adapter-level frame cap is retained. (Early builds gated frames behind a char throttle; removed in favor of fire-and-forget + identity dedup.) - Per-turn isolation: each turn owns a unique turn_id; concurrent messages are isolated via (chat_id, turn_id)-keyed state. Dual-lane priority queue (control vs normal) plus a per-chat token bucket to stay under WeCom's rate limit (errcode 846607). - Dedup-safe delivery + ack-race handling: deliver-once contract (a frame is delivered the moment it is emitted; failures logged, not re-sent; delivery marked once per turn), per-req_id reply queue with ack tracking, and the timeout-inversion / orphan-queue race fixes. Robust fallback on 846608 / 846609 / errcode 6000 / passive-reply timeout via proactive send. - Interaction boundaries: finalize + reset before approval/clarify prompts so the prompt is the last thing on screen and never traps a lingering bubble; eager re-seed after a clarify answer so the typing bubble reappears instantly. - Stream-level keepalive: optional periodic finish=false frame + finalize-time stream-age guard to refresh WeCom's ~6-minute reply-stream window on long turns (mitigates 846604 / 846608). Off by default; tunable via config.yaml. - Tool-progress folded into the same native-stream bubble instead of separate messages; image+text double-callback merged into one turn. Tests cover the streaming lifecycle, per-turn isolation, duplicate-send / ack timing, approval + clarify boundaries, eager re-seed, and tool-progress. |

fix(gateway): scope draft-final finalize skip to fresh persistent sends
The salvaged skip condition keyed on _use_draft_streaming alone, which also suppressed the explicit REQUIRES_EDIT_FINALIZE pass when a draft-streaming run had degraded to edit-based delivery (draft failure fallback sets _message_id). Key the skip on the got_done update being a fresh persistent send through the native-draft transport (_message_id is None), which is the only case where the update already carried its own finalize. |

feat(relay): live-card ops — native draft streaming + task cards over the relay (gateway half) (#85796)
* feat(relay): live-card ops — native draft streaming + task cards over the relay (gateway half)
NS-658. Three additive ops within contract v1, emitted only when the
connector's negotiated descriptor advertises them:
{op: draft, chat_id, draft_id, content, final, metadata}
{op: task_card, chat_id, card_id, chunks, metadata}
{op: task_card_stop, chat_id, card_id, metadata}
The gateway side is deliberately dumb: no platform API knowledge, no new
config keys. Slack mechanics (chat.startStream/appendStream/stopStream,
per-workspace feature-gate cache, send+edit fallback) live connector-side
where the platform adapter lives in the relay model.
Semantic bridge: base send_draft is Telegram-shaped (draft clears; final
is a separate send). Slack native streaming makes the stream THE message.
The adapter tracks the open draft per chat and converts the turn-final
send() into draft(final=true) so the connector seals the stream instead
of posting a duplicate; the stream ts returns as the message identity.
A failed frame disarms interception so the edit-based fallback's real
send goes through untouched.
BEHAVIOR CHANGE (deliberate): relay supports_draft_streaming() now
requires the descriptor flag AND the draft op. Flag-only was a latent
lie — send_draft inherited NotImplementedError, so a connector setting
the flag without the op would have crashed the stream consumer's draft
path. supported_ops stays fail-open for legacy (pre-contract) ops;
draft/task_card did not exist pre-contract and must not fail open.
Task cards ride #85476's adapter-agnostic TurnRunner seam (hasattr on
send_native_task_card_progress); supports_native_task_cards() is the
descriptor probe. Connector half + E2E harness pair follow in the gg
repo.
* fix(relay): expose native_task_cards_enabled() on the relay adapter
Live-canary finding (Alice, staging): the TurnRunner's task-card lane
probes adapter.native_task_cards_enabled() (the native Slack adapter's
opt-in contract). The relay adapter only offered
supports_native_task_cards(), so the hasattr gate failed silently and
tool progress stayed on the text path — draft streaming worked, cards
never rendered. Alias it to the descriptor probe.
* fix(relay): match task-card methods to the TurnRunner's native keyword contract
Live-canary finding #2 (Alice, staging): gateway/run.py's card lane calls
send/stop_native_task_card_progress with the NATIVE Slack adapter's
signature (tasks/title/reply_to/metadata/fallback_text, keyword-only) —
PR 85796's relay methods took a positional card_id, so every call raised
TypeError('unexpected keyword argument reply_to') in the progress task,
repeatedly killing the card publisher (and the retry loop resent the
final delivery 4-5x). Card id now derives per turn thread
(turn:<reply_to>), thread_ts anchored like draft; title/fallback_text
accepted for parity, not forwarded (plan-mode stream renders chunks).
* fix(relay): one draft stream per turn for stream-is-the-message adapters
Live-canary finding #4 (Alice, staging): the stream consumer bumps
draft_id at every tool boundary so Telegram-shaped drafts animate each
text segment as a fresh preview. On relay Slack NATIVE streaming a new
draft_id opens a brand-new chat.startStream — the user saw one frozen
message per segment (stuck streaming cursor ▉, never sealed: only the
LAST stream gets the final=true seal) plus the real final; 5-6 cumulative
snapshots per turn. Adapters that mark draft_stream_is_message keep ONE
stream per turn: tool progress lives in the native task card, and the
connector's suffix-delta falls back to whole-text append on prefix
mismatch, so segments append cleanly. Telegram-shaped drafts keep the
per-segment bump.
* fix(relay): don't seal the native stream at tool boundaries — only the turn-final does
Live-canary finding #5 (Alice; supersedes the incomplete #4 which was
necessary but not sufficient). Root cause CONFIRMED by integration trace
(test_live_cards_flow_trace.py, real consumer semantics + real adapter +
stub transport): at every tool boundary the consumer calls
_send_or_edit(finalize=True), which skips the draft path and issues a
real send(); the relay adapter's seal-interception converts THAT into
draft(final=true) — sealing the stream once per segment. Timeline showed
3 seals for a 3-segment turn: exactly the frozen cumulative ▉ snapshots
seen live (the replaced stream never gets stopStream, keeping its cursor).
Fix: for draft_stream_is_message adapters, a segment-break finalize
(finalize=True, is_turn_final=False) stays ON the draft path as another
cumulative frame; only got_done (is_turn_final=True) falls through to
send() and seals. Telegram-shaped platforms unchanged. Trace test now
pins the invariant: ONE user-visible message per turn.
* fix(relay): strip the text cursor from native draft frames
Live-canary finding #6 (Alice) — the ACTUAL duplicate-content mechanism,
confirmed by full-flow scan of both sides' code + logs. The consumer
appends its text cursor (▉) to every non-final display_text tick. The
connector's stream sender diffs CUMULATIVE frames via prefix check:
'abc▉'.startsWith → 'abc def▉' is NEVER a prefix match (the cursor sits
mid-string), so deltaFor falls back to whole-text append on EVERY tick —
chat.appendStream stacks each full cumulative snapshot (cursor included)
into the ONE stream message. Exactly the observed thread: repeated
blocks, each ending in a frozen ▉, growing per tick.
Fixes #4/#5 were real (one stream per turn now) but this was the last
mechanism standing. Native streams render their own typing indicator, so
the text cursor is pure noise on this path: strip it from draft frames.
Prefix check now holds; every tick appends only its true suffix delta.
* fix(relay): seal-interception covers EVERY egress door, not just send()
Live-canary finding #7 (Alice): one duplication remained after #6 — the
stream froze mid-word with the live indicator (never sealed) and the
final posted as a separate message. Log receipt: 'Queued follow-up:
final text delivery confirmed; delivering explicit media before
continuing' — the turn's final went out via the DELIVERY RESOLVER lane
(gateway/delivery.py), which calls send_for_platform() DIRECTLY,
bypassing send() and its seal-interception. The open stream never
absorbed the final; it arrived as a plain 'send' op → chat.postMessage.
Fix: hoist the open-draft check to the top of send() (ahead of the
explicit-platform branch) AND add it to send_for_platform() — an open
native stream absorbs the turn-final regardless of which egress door it
arrives through. The stream IS the message.
* fix(relay): failed seal falls back to plain send (PR 85796 AI-review point 1)
A turn-final seal that fails at the transport must never swallow the
final answer: the stream consumer has already disabled the draft
transport for the run, so a failed _seal_open_draft returning
success=False meant the user got NOTHING. Both seal-interception sites
(send + send_for_platform) now fall through to the regular plain-send
path on seal failure, with a warning receipt. Also mitigates AI-review
point 2 (sticky _open_draft_by_chat after an abandoned turn): a stale
entry's failed seal no longer blocks the next turn's delivery.
* fix(relay): arm seal-interception optimistically; never disarm on ambiguous failure (audit G-D1)
Deep-audit defect G-D1 (HIGH): the outbound leg is at-most-once on the
wire but its ack channel is lossy — send_outbound timeout (30s) and
WS-drop 'failures' frequently mean the frame WAS delivered and the
connector stream is open. send_draft popped _open_draft_by_chat on any
failure, disarming seal-interception while the connector stream lived:
the turn-final went out as a plain send → orphaned mid-word stream +
complete duplicate final (intermittent; needs a drop/timeout inside the
draft window).
Fix: arm the entry BEFORE the transport call and keep it armed on
failure/exception. Safe in every case: sealing a non-existent stream
opens+seals a single complete message connector-side, and a truly failed
seal already falls back to plain send at both interception sites.
Stale-entry damage is self-healing (one warning + plain send).
* fix(relay): gateway-side sealed-draft tombstone — G-D1 arming must not resurrect sealed streams
Regression fix on G-D1 (live: 'worse than before' — escalating frozen
prefixes). Optimistic arming had no seal-awareness: a straggler frame
arriving AFTER the seal re-armed _open_draft_by_chat for the already-
sealed draft_id; the next send was converted to draft(final=true) on the
tombstoned connector key, which CLEARED the connector tombstone (final
frame = new-turn signal), re-opened a stream with cumulative content,
and left it frozen — repeating per straggler: 4-5 escalating frozen
snapshots. Mirror the connector: _sealed_draft_by_chat records the
sealed draft_id per chat (tombstoned BEFORE the seal's transport call);
send_draft for a sealed draft_id is a success no-op (content already in
the sealed message) and never arms. A new turn's fresh draft_id arms
normally.
* fix(relay): key stream/card state per (chat, turn anchor) — parallel turns must not collide (finding #10)
Live finding #10 (Alice; three concurrent turns in one flat DM): all
coordination state was keyed per CHAT on a one-active-turn assumption.
Three parallel turns produced: turn B's task card merged into turn A's
(both were card 'turn:root' — reply_to is None in flat DMs), B left
cardless, and _open/_sealed_draft_by_chat clobbered across writers (3x
duplicate finals on the last turn). Per-turn machinery was correct;
the keys were not.
Fix: _draft_key(chat, metadata) = chat + the turn's thread anchor
(inbound stamps thread_ts = event.thread_ts or ts on every top-level
message, so each turn has one even in flat DMs). draft arming, seal
tombstones, both interception sites, and the task-card id all derive
from the same anchor. New trace test pins two interleaved turns:
distinct cards, own-stream seals, no leaked plain send, no cross-turn
tombstone drops (289 tests green).
* fix(gateway): preserve cumulative native stream across tools
* fix(gateway): consumer-declared final — the seal carries the true final
Three composed fixes for the Slack live-cards duplicate-final class:
1. finish(final_text): TurnRunner passes the completed final_response
(verifier footer, completion explainer included) as the authoritative
finalize payload. The native-stream seal delivers the TRUE final, so
post-stream mutation no longer forks a corrective plain send (#11).
2. Interim-send contract: commentary and segment-tail sends carry a
gateway-internal _interim_send marker; relay seal-interception skips
them at both egress doors. A mid-turn interim send can no longer seal
the live stream and orphan the real final into a duplicate.
3. Queued-follow-up lane reconciles an unconfirmed final by EDITING the
consumer's delivered message in place (sealed stream = regular
message, chat.update live-verified); plain send only as fallback.
This was the actual duplicate lane in the parallel canaries — every
duplicated turn logged 'final stream delivery not confirmed; sending
first response' (subagent-completion queued inbound), not parallelism.
Also: draft frames stay prefix-stable gateway-side (no fence-closing, no
segment state reset, no commentary reset for stream-is-the-message
adapters; MagicMock-safe 'is True' guards).
* test+docs: streaming-contract coverage completeness + maintenance guidelines
Coverage: two gaps closed on the consumer-declared-final contract —
(1) send_for_platform (the delivery-resolver egress door) honors the
_interim_send contract: no seal, marker stripped before the wire;
(2) finish(final_text) on a turn that never streamed does not adopt the
final (delivery ownership stays with the gateway's normal send path for
non-streaming models / tool-only turns).
Docs: AGENTS.md 'Known Pitfalls' gains the streaming delivery contract —
the four invariants of stream-is-the-message adapters (prefix-stable
frames, consumer-declared final, interim-send marker, reconcile-by-edit),
each traced to its live incident, plus the live-probed Slack streaming
API ground truth and the MagicMock 'is True' guard-style note.
* fix(relay): seal transport failure must never silently lose the final (review B1)
Two halves of one silent-loss path, live-probed on the review branch:
1. adapter: _seal_open_draft did not catch transport exceptions. A socket
drop at seal time raised out of send(), skipping the fail-open plain
send entirely. Now: retry the SAME idempotent final frame once (the
connector's sealed-key tombstone returns the original stream ts for a
repeated final — a retry can never open a second stream or duplicate),
then report failure so the caller's fail-open path runs.
2. consumer: the turn-final retry (elif not _already_sent) called
_send_or_edit with finalize=False, which re-entered the DRAFT-FRAME
branch. Its no-op dedupe compared the adopted final against the last
unsealed frame, matched, and returned True with ZERO transport calls —
final_response_sent went green, delivered_final_matches reconciled,
the gateway suppressed its fallback, and the user never received the
answer. finalize=True keeps this retry out of the draft branch.
Regression suite: tests/gateway/test_relay_seal_failure.py (3 tests).
Mutation evidence in follow-up verification: reverting either half sends
the suite red.
* fix(relay): draft ids unique across gateway incarnations (review B3)
The relay connector tombstones sealed streams by (channel, draft_id) and
keeps up to 512 of them; they outlive the gateway process. Relay gateways
are disposable BY DESIGN (scale-to-zero), and _draft_id_counter restarted
at zero every incarnation — so the first turns after every scale-from-zero
in a recently-active channel replayed already-sealed wire identities. The
connector answered those frames straight out of the old tombstone: zero
Slack API calls, the OLD message ts returned as the new turn's identity,
the new answer silently dropped while gateway-side flags recorded success.
Seed the counter from wall-clock milliseconds at process start. Ids stay
plain ints within the existing contract op; incarnations cannot overlap
for realistic turn counts and restart gaps.
Regression: tests/gateway/test_draft_id_restart_uniqueness.py — the seed
test fails on the old code (seed 0 is not epoch-scale).
* fix(relay): stream/card state keyed per TURN, not per thread anchor (review B2)
The thread anchor is the wrong coordination identity — simultaneously:
- too coarse: two parallel turns replying INSIDE ONE Slack thread share
thread_ts. Live-probed on the review branch: turn A's final sealed turn
B's stream with A's content while A's own stream stayed open, and B's
final degraded to a plain send.
- too fragile: a flat DM with no thread metadata degraded to the bare
chat id, re-creating the original finding-#10 collision the anchor was
meant to fix.
_draft_key now prefers the triggering inbound message id (message_id /
reply_to_message_id — per-turn by construction; the gateway's Slack
thread metadata and the consumer's send path both stamp it), falling back
to the thread anchor, then the bare chat. The consumer stamps the same
reply_to_message_id on draft frames so frames and the turn-final resolve
to one key. Task-card ids share the derivation via _card_key (one helper
for send AND stop, so the stop always hits the stream the send opened).
Legacy resolver-lane callers with placement-only metadata still seal via
_match_open_draft's fallback — but ONLY when exactly one stream is open.
With several open, an identity-less send stays a plain send: a duplicate
message is recoverable, sealing someone else's stream is not.
Regression: tests/gateway/relay/test_relay_turn_keying.py (7 tests).
* fix(relay): stream-is-the-message is a Slack semantic, gate it on the descriptor (review B4)
draft_stream_is_message was hardcoded True on the relay adapter class,
i.e. for EVERY relay platform. The base send_draft contract is
Telegram-shaped — the draft clears client-side and the final arrives as
a separate real send that becomes the history message. With the flag
forced on, any non-Slack connector advertising the draft op had its
turn-final intercepted into draft(final=true): probed on the review
branch with a telegram descriptor, the op stream was
[draft(final=false), draft(final=true)] and NO send — no history message
would ever be posted.
Gate the flag on the negotiated descriptor platform (slack), and skip
arming seal-interception entirely when it is off. A future platform with
genuine stream-is-the-message native streaming should advertise it via
the descriptor rather than widening the platform check by guesswork.
Regression: tests/gateway/relay/test_relay_stream_semantics_gating.py
(4 tests: gating both ways, telegram final is a real send, slack final
still seals).
* fix(gateway): mark every mid-turn status lane interim — heartbeats must not seal the stream (review B5)
Seal-interception treats the first unmarked send to an armed (chat, turn)
key as the turn-final. The consumer's own interim lanes (commentary, tail
flush) carry _interim_send, but four gateway-side lanes that fire DURING
a streaming turn did not:
- long-running heartbeat (default every 180s — probed live: at 3 minutes
it sealed the live stream with '⏳ Working — 3 min', the real final
posted as a duplicate, and later frames were silently swallowed by the
seal tombstone)
- inactivity warning
- plain-text approval fallback (button lane failed)
- background-review notice
Add _interim_metadata() beside _non_conversational_metadata and wrap all
four call sites. The marker is gateway-internal; the relay adapter strips
it before the wire (existing behavior, pinned by test).
Note for follow-up: the opt-out shape remains fragile — any FUTURE
unmarked mid-turn send lane re-creates this bug. Inverting the contract
(explicitly mark the one turn-final send) is the durable fix but touches
every adapter's final-delivery path; deliberately kept out of this
review-fix series.
Regression: tests/gateway/test_interim_send_lanes.py (4 tests).
* fix(gateway): interrupted/incomplete turns must not adopt the diagnostic as the stream final (review B6)
The finish(final_text) adoption gate checked only 'not failed', but the
interrupt/abort returns in agent/conversation_loop.py are
{completed: False, interrupted: True, final_response: 'Operation
interrupted during …'} with NO failed key. Adopting that diagnostic:
1. sealed the user's streamed partial answer over with the interrupt
text (stream-is-the-message: the seal rewrites the whole message), and
2. recorded the diagnostic as the turn-final payload, so
delivered_final_matches reconciled and the gateway suppressed its own
error-delivery path — the diagnostic became the ONLY thing delivered.
Enumerated all 27 final_response-bearing return shapes in
conversation_loop.py: every non-happy-path shape carries completed:
False (several with a diagnostic final_response and neither failed nor
interrupted — retry exhaustion, truncation, codex-incomplete); the happy
path routes through turn_finalizer.finalize_turn (completed=True). Gate
is therefore: not failed AND not interrupted AND completed is not False.
Results lacking the completed key entirely (older callers/test doubles)
keep the previous behavior.
Regression: tests/gateway/test_stream_final_adoption_gate.py (6 tests,
incl. a source-level pin on the run.py call site).
* fix(relay): task-card transport failures degrade to failed SendResults (review B7)
send_native_task_card_progress and stop_native_task_card_progress let
transport exceptions escape. The stop runs inside the progress loop's
finally block on the turn-cleanup path, and the post-cancel awaits in
gateway/run.py caught only CancelledError — a socket drop during a card
publish/stop therefore aborted cleanup BEFORE the final-delivery
bookkeeping ran.
Three layers, outermost defends any adapter:
- both adapter methods catch transport exceptions and return failed
SendResults (progress is advisory; the TurnRunner's text fallback
already handles failure results)
- the progress loop's finally wraps the stop (best-effort; the connector
seals orphaned card streams on its own via recycling/eviction)
- the cleanup awaits log-and-continue on non-cancellation errors so
final-delivery bookkeeping always runs
Regression: tests/gateway/relay/test_relay_task_card_failures.py.
* fix(relay): a dying turn seals its native stream instead of orphaning it (review B8)
Stale-generation exits (/new, /stop mid-stream) and cancellations
returned from the consumer's run() with the native stream still open:
- the Slack message kept its live streaming indicator forever (the
cancellation best-effort edit only runs when _message_id exists, and
the native draft path deliberately keeps it None);
- the adapter's armed interception state survived the turn, so the next
turn on the same key could inherit it and seal a dead draft_id.
New adapter op abandon_open_draft(chat, content): seals in place with
the text already on screen (the consumer passes its last delivered
frame) — the seal adds nothing and claims nothing; delivery flags are
never set, so the gateway's normal paths still own whatever happens
next. Best-effort by contract (failure reported, never raised); the
connector reaps truly orphaned streams via recycling/eviction.
The consumer calls it from both death paths: the stale-generation early
return and the CancelledError handler.
Regression: tests/gateway/test_stream_abandon_on_turn_death.py (4 tests,
incl. the next-turn-inheritance hazard).
* fix(relay): bound the draft/seal coordination dicts (review M1)
_sealed_draft_by_chat's key embeds a per-turn identity, so every
completed turn wrote a permanent entry — unbounded growth for the life
of a long-running gateway process (the docstring said 'one entry per
chat', which stopped being true when the key gained the turn anchor).
_open_draft_by_chat could grow the same way via abandoned entries.
FIFO-evict both at 512 entries — the same idiom as the sibling bounded
cache (_auto_thread_by_chat, capped at 256) and the same size as the
connector's own tombstone store. The straggler window the tombstone
exists for is seconds long; FIFO is more than enough.
Regression: tests/gateway/relay/test_relay_state_bounds.py.
* fix(relay): explicit connector rejection disarms interception; exceptions stay armed (review P3)
The G-D1 optimistic-arming change silently dropped disarm-on-failure
entirely: after an EXPLICIT connector rejection (success=False result —
not a transport ambiguity), interception stayed armed even though the
stream consumer disables the draft transport on that failure and falls
back to edit-based streaming. Its turn-final would then be converted
into a seal on a stream the connector just told us is unusable.
test_draft_failure_result_propagates claimed to cover this ('must NOT
leave seal-interception armed') but passed for an unrelated reason: the
stub's canned failure also failed the SEAL, whose fail-open path did the
plain send.
Split the two semantics and pin each honestly:
- explicit rejection (result success=False): disarm — turn-final is a
real send (test_draft_failure_result_propagates, now testing what its
comment says)
- transport exception: ambiguous, stay armed — turn-final still seals
(test_draft_transport_exception_keeps_interception_armed, the G-D1
contract)
Also corrects commit ba3a24a's claim ('a failed frame disarms
interception so the edit-based fallback's real send goes through
untouched') to hold again for the rejection case it described.
* fix(relay): lost acks are ambiguous, not rejections — on the RESULT channel too (review r2, finding 1)
The production ws transport does not raise on ack timeout — it returns
{"success": False, "error": "relay outbound timed out"}. The round-1
ambiguity handling keyed entirely on the exception channel, so the shape
production actually produces was misclassified as a definite connector
rejection. Probed on the head:
- lost SEAL ack: skipped the idempotent retry, fell straight to a plain
send — duplicate final whenever the seal had actually applied;
- lost FRAME ack: the round-1 disarm-on-rejection fired — interception
disarmed, frozen native stream beside a plain final. This re-created
the original G-D1 ambiguous-ack defect on the result channel.
Contract now spans both channels:
- transport: the ack-timeout branch tags ambiguous=True. The fail-fast
branches (closing / not connected) never sent anything and stay
unmarked — they are definite non-delivery.
- adapter frame path: ambiguous results keep interception armed (same
as exceptions); only definite rejections disarm.
- adapter seal path: one shared _attempt() classifier — exception and
ambiguous result both mean "unknown"; the SAME idempotent frame is
retried once (connector tombstone returns the original stream ts for
a repeated final). Only after both attempts stay ambiguous does the
caller's fail-open plain send run: a possible duplicate after double
ack loss beats a silent loss, and double ack loss on one socket
almost always means the transport is down for the plain send too.
Regression: tests/gateway/relay/test_relay_ack_ambiguity.py (6 tests,
incl. a source-of-truth check that the transport tags the timeout branch
and leaves fail-fast branches unmarked).
* fix(relay): stream semantics + draft capability resolve per CHAT, not per primary (review r2, finding 2)
One RelayAdapter fronts N platforms (Phase 1.5): descriptors accumulate
per platform on the transport and egress is tagged per chat — but the
round-1 gate keyed draft_stream_is_message and supports_draft_streaming()
off the PRIMARY scalar descriptor. Probed on the head:
- Slack primary + Telegram chat: the Telegram chat's turn-final was
intercepted into draft(final=true) — no real Telegram history message;
- Telegram primary + Slack chat: the Slack chat was denied native
streaming entirely.
Resolve both through _descriptor_for_chat — the same per-chat machinery
max_message_length already uses (added for the identical class of bug:
the primary's 39000-char cap over-sending into Discord 400s):
- new stream_is_message_for_chat(chat_id) on the adapter; arming and
NotImplementedError gating use it. The class attribute remains as the
single-platform value and legacy-probe fallback.
- supports_draft_streaming() gains an optional chat_id kwarg (base
signature updated; single-platform adapters ignore it). The consumer
passes chat_id with a TypeError fallback for out-of-tree adapters.
- the consumer's four draft_stream_is_message reads collapse into one
_stream_is_message() helper that prefers the per-chat probe
(class-resolved, MagicMock-safe) over the attribute.
Platform-name inference ("slack") stays deliberate: a descriptor-level
semantic field is the right eventual contract but is a cross-repo wire
change — noted for the gg follow-up so future platforms advertise the
semantic explicitly.
Regression: tests/gateway/relay/test_relay_multiplatform_semantics.py
(5 tests: both starvation directions, scalar fallback, per-chat
capability gate).
* fix(gateway): split delivery + authoritative footer reconciles by suffix, not full resend (review r2, finding 3)
The _FINAL_TEXT adoption guard refuses wholesale adoption on split turns
— correct (#78541: sealed heads would repeat inside the tail) but it was
absolute: a post-split verifier footer never entered the ledger,
delivered_final_matches() reported a mismatch, and the gateway resent
the ENTIRE body+footer after the split chunks (the #11 duplicate class,
one level up).
When the authoritative final strictly prefix-extends the split ledger,
the missing suffix is the only undelivered content: append it to the
live tail and the ledger, so the finalize carries it and the recorded
payload reconciles. Non-prefix rewrites keep the full-resend fallback —
a rewrite cannot be patched onto sealed heads.
Regression: tests/gateway/test_split_final_suffix_reconcile.py (3 tests:
suffix rides the tail + reconciles, rewrite still mismatches, unsplit
adoption unchanged).
* fix(relay): cancellation mid-seal restores open state so abandon can close the stream (review r2, finding 4)
_seal_open_draft pops the open entry and writes the local tombstone
BEFORE awaiting transport I/O — correct ordering for the straggler race,
but CancelledError is not an Exception: a cancel during the await
bypassed all failure handling, leaving the remote stream live (visible
streaming indicator until connector eviction) while the local state said
'nothing open'. The consumer's abandon pass — added for exactly this
turn-death case — found nothing to close and no-oped.
On CancelledError: restore the open entry, drop the premature tombstone
(only if it is still ours), re-raise. The abandon path then seals the
stream in place with the on-screen text.
Regression: tests/gateway/relay/test_relay_seal_cancellation.py (2
tests: state restoration, and end-to-end cancel→abandon→remote seal).
* fix(relay): thread anchors are placement, not turn identity — revive the placement-only fallback (review r2, finding 5)
_match_open_draft's single-open-stream fallback was dead for its primary
intended callers: metadata carrying thread_ts/thread_id (placement-only
resolver lanes) was classified as having 'turn identity', so those sends
never reached the fallback — probed: a plain final posted beside the
still-open turn-keyed stream.
Only per-turn MESSAGE ids are identity now. Thread-anchored and bare
callers share the fallback: absorb into the chat's open stream when
EXACTLY one is open; stay a plain send when several are (duplicate is
recoverable, wrong-stream seal is not). Callers WITH a message id whose
key misses never fall back — their identity is authoritative and a miss
means the stream belongs to a different turn.
Regression: 4 new tests in test_relay_turn_keying.py (thread-anchored
seal, both ambiguous-stay-plain shapes, id-mismatch never steals).
* fix(relay): random process nonce for draft-id seeding (review r2, follow-up 6)
The epoch-millisecond seed (round-1 B3 fix) mitigates the restart-replay
class but is not a uniqueness guarantee: two gateways starting in the
same millisecond, a forked process inheriting the class state, or a
clock step backwards can all mint colliding wire identities against the
connector's per-(channel, draft_id) tombstone store.
Seed from secrets.randbits(49) instead: collision probability negligible,
no clock dependence, and ids + realistic per-process turn counts stay
comfortably inside the connector's JS number range (draft_id?: number,
2^53). Regression test now spawns two real interpreters and asserts
their seeds differ — the exact scale-to-zero restart shape, and both
start within the same second so a clock-locked seed would fail it.
* fix(relay): stamp per-turn Slack egress identity — cache is fallback only (R3-5)
The connector (gateway-gateway#210) fills chat.startStream's
recipient_user_id / recipient_team_id — required by Slack when
streaming to a channel — from metadata.user_id / metadata.scope_id.
The gateway stamped only slack_team_id per-turn and left user_id (and
scope_id) to RelayAdapter._with_scope, whose per-chat caches are keyed
on chat_id alone and overwritten by every inbound message: with users
U1 and U2 running overlapping turns in one channel, U2's arrival
overwrote the cache before U1's stream opened, and U1's stream carried
U2 as recipient_user_id.
_thread_metadata_for_source now stamps scope_id and user_id from the
turn's OWN source (setdefault — explicit values win), so identity is
turn-scoped data on the wire. _with_scope is unchanged and fill-only:
the caches keep serving restart/synthetic sends that carry no per-turn
identity, which is all they were ever safe for.
Mutation evidence: reverting the run.py hunk sends
test_thread_metadata_stamps_per_turn_user_and_scope and
test_concurrent_turns_carry_their_own_identity red; restore returns
green. The _with_scope fill-only tests pass on both trees (existing
correct behavior, now pinned against regression).

fix(gateway,relay): stop frozen-preview finals and dropped idle-session delegation callbacks (#82592)
* fix(gateway): stop frozen-preview finals and dropped idle-session delegation callbacks
Two relay-plane delivery losses from the 2026-08-09 staging incident:
1. stream_consumer: the skip-redundant-finalize branch recorded _accumulated
as the delivered turn-final payload even when the last ACKED edit was an
earlier throttled preview snapshot, so delivered_final_matches reconciled
True and the gateway suppressed the corrective final send — the user was
left with a cut-off message ending in the streaming cursor. Extracted
_mark_skip_redundant_finalize(): records the last acked wire payload
(cursor-stripped), so a preview/final mismatch now returns False and the
normal final send fires.
2. run.py: _classify_completion_target classified every ended parent session
terminal unless it ended by compression. Idle/timeout session ends are the
norm on scale-to-zero relay deployments and the chat route remains valid;
completed async delegation results were terminally dropped. Ended parents
now classify deliver unless the end was an explicit user boundary
(session_reset / user_exit / session_switch).
* fix(relay): drain in-flight outbound frames before transport teardown
disconnect() failed every pending outbound future immediately with
'relay transport closed', so a trailing finalize edit racing turn
teardown was lost even though the connector socket could still serve
it. Bounded drain grace (5s) lets in-flight requests resolve; silent
connectors still tear down promptly. asyncio.wait (not gather+wait_for)
so a timeout doesn't cancel futures owned by the fail-remaining loop.
* fix(gateway): route completion injection through the alias-aware transport resolver
Third relay-plane delivery loss from the 2026-08-09 staging incidents: a
delegation batch completed while the gateway was up, the watcher drained
the event, and delivery vanished with no log line. _inject_watch_notification
resolved its adapter with a literal p.value == platform_name scan of
self.adapters — a relay-fronted gateway registers ONE adapter under
Platform.RELAY fronting N logical platforms, so 'slack' never matched and
the injection returned None ('no gateway route'), silently dropping the
completion. The handoff path already documents this exact trap and uses
resolve_delivery_transport; the injection path now does the same (native
wins; relay eligible only when it fronts the logical platform), with the
literal scan kept as fallback for stub runners and exotic platforms.
* fix(relay): clamp disconnect drain grace to the runner's adapter-disconnect budget
Review finding (JoaoMarcos44, #82592): a fixed 5.0s drain in front of the
three 1.0s sequential teardown awaits gives an 8.0s worst case inside the
runner's 5.0s asyncio.wait_for(adapter.disconnect()) — tripping it cancels
teardown mid-drain, skips the fail-pending loop, and leaves outbound
callers blocked until _OUTBOUND_TIMEOUT_S (30s). The effective grace is
now budget - 3*TEARDOWN - margin (env-aware via the same
HERMES_GATEWAY_ADAPTER_DISCONNECT_TIMEOUT the runner reads), so the drain
can never push teardown past its caller's budget; a budget too small for
any drain disables it cleanly.
* test(gateway): pin the final-send suppression contract across a behaviour matrix
The gateway skips its own final send when the stream consumer claims the turn
final already reached the user. Every incident in that family — #71643 (stale
finalize snapshot), #78541 (payload-less multi-message split), #82656 (frozen
preview left with a visible cursor) — is the same failure: the consumer claimed
delivery for text the platform never rendered, so the corrective send was
suppressed and the answer was lost with no retry.
Each was fixed with a scenario test pinned to one branch of
GatewayStreamConsumer.run(). The got_done handler now has five sibling branches
that each set the suppression flags and record a turn-final payload, and nothing
checks them as a group: a new branch, or a new early `return True` in
_send_or_edit, can reintroduce the class without failing a test.
Pin the invariant instead of the branch — if the consumer offers the gateway any
signal it would trust, the complete final text must have reached the wire — and
assert it across {edit always / dies / never / lies} x {send always / never} x
{fresh-final on / off} x {clean / interrupted stream}.
The adapter records only frames that actually rendered, so an ACK the platform
drops does not count as delivery. 24 honest-transport scenarios hold the
invariant as a hard assertion. The 16 lying-transport scenarios are checked too;
the single combination that still violates it is reported as an expected
failure documenting the open exposure rather than asserting it away.

* fix(gateway,relay): prime relay egress routing for synthetic injections + cap stale completion replay
Defect #4 from the 2026-08-09 staging incidents (upgrade-robustness):
after every gateway restart the durable async-delegation replay injected
completions correctly (post-741663cf1) but their replies bounced at the
connector — 'slack egress declined: target not routed to an onboarded
tenant'. The relay adapter re-attaches tenant discriminators
(metadata.scope_id / metadata.user_id) from per-chat caches warmed ONLY by
inbound traffic; synthetic turns race those cold caches on every deploy,
scale-to-zero wake, and crash recovery.
- relay adapter: prime_routing_cache() — feeds a synthetic event's
session-store origin through the same _capture_scope used for real
inbound (never raises).
- run.py injection path: prime the resolved adapter before handle_message
(duck-typed; native adapters unaffected).
- async_delegation: 48h staleness cap in restore_undelivered_completions —
a pending completion older than the cap is terminally dropped (payload
stays queryable) instead of re-run as a fresh full-context turn; the
post-restart replay of a July session burned a 102K-token context.
Also carried: JoaoMarcos44's suppression behaviour-matrix harness
(cherry-picked from #82676, authorship preserved) — 39 passed + 1 xfail
(the documented ACK-then-drop transport-honesty residue).
* test: use recent timestamps in restored-ownership fixtures
test_restore_stamps_restored_flag persisted its completion with epoch-era
toy timestamps (dispatched_at=1.0), which the new 48h replay staleness cap
correctly classifies as stale — the fixture then exercised the cap instead
of the restored-flag contract (CI slice 4 failure). Timestamps are now
now-relative; the staleness behavior itself is pinned separately in
test_relay_injection_egress_priming.py.
* fix(gateway,relay): close four review findings on the relay delivery fixes
Review follow-ups on this branch (NousResearch#82592):
1. HIGH — classifier/resolver mismatch (falsely-acknowledged loss).
_classify_completion_target now returns "deliver" for idle-ended
parents, but _resolve_async_delegation_session still dropped every
non-compression-ended pin: the durable row was acked at adapter
acceptance, then the injection died inside the pipeline with no
retry — strictly worse than the honest terminal drop on main, and
the delivery leg defect #2's fix depends on did not exist. The
resolver now retargets non-user-boundary ends (idle/timeout/
lifecycle) to the chat's current session — session_entry already IS
the routing key's current session for the same chat — while user
boundaries (session_reset / new_session / user_exit /
session_switch) stay fail-closed. Both sides share one module-level
_USER_BOUNDARY_END_REASONS so the verdict and the routing decision
cannot drift again; a coherence test asserts deliver-verdicts
resolve non-None across representative end reasons.
2. HIGH — drain clamp missed adapter-level spend. The effective drain
grace budgeted drain + 3x teardown, but RelayAdapter.disconnect
spends revocation-monitor teardown + go_idle time BEFORE the
transport drain inside the same runner wait_for; worst case still
blew the budget and cancelled teardown mid-drain (skipping the
fail-pending loop). The adapter now measures its own elapsed time
and threads the REMAINING budget into
transport.disconnect(budget_s=...); legacy/stub transports without
the keyword fall back to the no-arg signature.
3. P1 — _request_response racing disconnect() could register a future
after the fail-pending loop already ran, stranding the caller for
the full _OUTBOUND_TIMEOUT_S (30s). Fail fast with the same
"relay transport closed" error once _closing is set.
4. P1 — _build_process_event_source's last-resort reconstruction
dropped scope_id, so a scoped relay completion whose session-store
origin was unavailable primed no tenant discriminator and could
still bounce off the connector's fail-closed egress guard.
scope_id now threads through the reconstructed SessionSource, with
a warning when a scoped chat reconstructs without one.
All four: RED reproduced with the fix reverted, GREEN after; relay/
delegation delivery families pass (43 + 71 + 179 across the touched
suites); full tests/gateway run shows only failures already failing
identically on merge base

fix(gateway): don't claim deleted head chunks as delivered in the empty-fallback recovery
Follow-up to #79669. That PR routed the three fallback recorder sites through _record_turn_final_payload so a split turn would record the unsplit ledger instead of a tail-only payload. For two of them that is right. For _send_empty_fallback_final it is wrong, and it reintroduces the #78541 swallow at the one site that was supposed to be fixed. _send_empty_fallback_final is a *replacement* recovery: it sends the completed text as a fresh message and deletes every tracked segment preview -- which on an overflow split includes the sealed head chunks. After it runs, the only thing on screen is the message it just sent. Recording the ledger there claims delivery for text the same function just removed, so delivered_final_matches() returns True, the gateway suppresses its own send, and the user is left with a fraction of the answer. Observed with a probe driving the real run() loop (543-char reply, 475-char head sealed then deleted, 67-char tail committed): before this fix recorded=543 matches=True -> suppressed, 67/543 on screen after this fix recorded=67 matches=False -> gateway sends the full answer Record final_text verbatim here instead. The sibling site in _send_fallback_final keeps the recorder: its delete is gated on `continuation == final_text` and targets only the single active partial, never the sealed heads, so the ledger correctly describes what survives. The distinction is whether a recovery ADDS to what is on screen or REPLACES it. Additive paths may record the ledger; replacing paths must record only what they leave behind. _try_fresh_final is the same shape and #79669 handled it by refusing the route on split turns. Test drives the real seal-then-delete sequence and asserts the mismatch, so the gateway is required to re-send. Mutation-checked: restoring the recorder call turns it red. |

fix(gateway): finish the split-delivery bug class so the fix cannot duplicate or still swallow
The salvaged fix changed only the gateway's verdict: a payload-less multi-message split stopped inheriting legacy trust. But six code paths set _turn_split_delivery, and only one of them was taught to record a payload, so the remaining five swapped the swallow for the opposite defect. Fix the producers instead of only distrusting them at the boundary: - _send_or_edit failed-final-edit branch: record the visible payload on split turns too. It deliberately skipped recording, which now reads as a mismatch and re-sends an answer already on screen -- reintroducing the duplicate #45517 fixed (#36965 / #25349). - _send_fallback_final (x2) and _send_empty_fallback_final: route through _record_turn_final_payload instead of assigning _delivered_final_text directly. On a split turn their final_text is only the trailing chunk, so a fully delivered heads+tail reply recorded a tail-only payload and was re-sent in full. - _try_fresh_final: refuse the fresh-final route once a head chunk is sealed. It replaces every tracked preview with one message, which only holds the whole answer on a single-message turn. After a split it deleted the sealed heads while sending just the tail, so the complete reply was still lost -- on Telegram, the default finalize route and the shape #78541 reports. - Set _turn_split_delivery at seal time rather than after the tail send, so the tail's own finalize sees the split state. The sibling overflow path already did this; the divergence is what let fresh-final delete the heads. - run.py stale-finalize reconciliation: skip the in-place edit on a split delivery. message_id is only the LAST chunk there, so editing it with the complete response repeated every sealed head's text inside the tail message. Fall through to the normal final send. Also drop a dead `or "".join(chunks)` fallback (all growth funnels through _append_accumulated, so the ledger is never empty at that call site, and joined chunks carry injected fence markers that could never match final_response), and document that _record_turn_final_payload intentionally ignores its argument on split turns. Tests: four end-to-end cases driving the real overflow-split loop instead of hand-setting private flags -- complete split still suppresses (no duplicate), split missing a tail does not suppress, fresh-final keeps sealed heads, and a flood-controlled final edit after a split stays suppressed. Each was mutation-checked: reverting any individual fix turns its test red. The pre-existing gateway-boundary test asserted the recovery *route* (the reconcile edit) rather than the guarantee. Relaxed to the real contract: either _run_agent puts the complete text on the wire, or it declines to claim delivery so the caller's normal final send does.

fix(gateway): stop payload-less split delivery from swallowing finals
Record an unsplit stream ledger for multi-message deliveries and refuse legacy trust when split delivery left no payload, so Telegram group sessions no longer suppress a complete reply after an early/partial finalize (#78541). |

fix(gateway): stop stale streamed finalize from suppressing the complete Telegram response
A successful finalize edit can carry only the last streamed preview snapshot: deltas generated between the last preview edit and stream completion never reach any Bot API call, yet final_response_sent / final_content_delivered were set from the call's success and suppressed the gateway's normal final send — losing the tail permanently. The stream consumer now records the exact cleaned payload of every turn-final delivery (delivered_final_matches tri-state), and gateway/run.py reconciles that record against the completed final_response before trusting either suppression flag. On a demonstrable mismatch it edits the streamed message up to the complete response, falling back to the normal final send if the edit fails. Multi-message split deliveries and legacy paths without a record keep the existing flag-trusting behavior, so overflow splits and the failed-finalize handling (#51828/#33793) are untouched. Fixes #71643 |

chore: remove unused imports and dead locals (ruff F401/F841 sweep)
Cleans F401 unused imports and F841 dead local assignments across root *.py, agent/, hermes_cli/, tools/, gateway/, cron/, tui_gateway/ (tests/, plugins/, skills/ excluded). Intentionally KEPT (false positives / test-patch surfaces): - agent/transports/__init__.py package re-exports - cli.py browser_connect re-exports (DEFAULT_BROWSER_CDP_URL area, used by tests/cli/test_cli_browser_connect.py) - hermes_cli/main.py _prompt_auth_credentials_choice / _model_flow_bedrock_api_key (accessed via main_mod attr in tests) - gateway/run.py aliased replay_cleanup + whatsapp_identity re-exports and _PORT_BINDING_PLATFORM_VALUES (test-referenced) - hermes_cli/web_server.py get_running_pid (tests monkeypatch it) and _OAUTH_TOKEN_URL availability probe - hermes_cli/config.py get_process_hermes_home re-export (noqa'd F811 chain) and yaml availability-probe import - hermes_cli/nous_subscription.py managed_nous_tools_enabled (tests patch hermes_cli.nous_subscription.managed_nous_tools_enabled) - try/except ImportError availability probes (env_loader, tts_tool, mcp_tool, web_server anthropic OAuth block) - tools/web_tools.py noqa F401 re-exports - hermes_cli/setup_whatsapp_cloud.py:263 'proceed' skipped: possible missing-guard bug, flagged for separate review - unused function parameters (signature changes out of scope) Side-effect RHS calls preserved where only the binding was dead (e.g. web_server proc = _spawn_hermes_action -> bare call). |

fix(relay): per-platform capability descriptors for multi-platform gateways (#70717)
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 — and the transport's read loop OVERWROTE it on every descriptor frame (last-writer-wins). A Discord chat on a gateway whose applied descriptor was Telegram's inherited the 4,096-char cap and over-sent into Discord's 2,000-char API 400 (observed live: 2,543/2,641-char replies silently lost while inbound kept working). - ws_transport: accumulate one descriptor per platform in _descriptors_by_platform (exposed via descriptor_for_platform); the FIRST descriptor of a connection generation stays the session default instead of last-writer-wins; the map resets on re-dial. - BasePlatformAdapter: new max_message_length_for_chat / message_len_fn_for_chat hooks defaulting to the scalar surface (native single-platform adapters unchanged). - RelayAdapter: overrides resolve the chat's platform from _platform_by_chat (the same map per-frame egress uses) and look up that platform's negotiated descriptor; falls back to the scalar for unknown chats/transports. - stream_consumer (streaming budget, _raw_message_limit, fallback-continuation chunking) + run.py tool-progress limit now resolve per-chat. Tests: tests/gateway/relay/test_relay_per_platform_caps.py (7) — verified fail-without/pass-with (all 7 fail with the fix stashed). Relay + stream consumer suites green (213 + 223). |

fix(gateway): balance code fences on every remaining chunk-split path
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. |

fix: also close orphaned single-backtick inline-code spans
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. |
