79c5832e1d MUL-5708 fix(taskfailure): classify response-side context-window overflow (#6366)
* fix(taskfailure): classify response-side context-window overflow (MUL-5708)

Claude Code 2.1.x reports an exhausted context window on the response,
not as a 400 on the request: the turn ends with stop_reason
"model_context_window_exceeded" and the CLI prints

    API Error: The model has reached its context window limit.

That string carries none of the phrases rule 1 matched and no "token",
so it classified as agent_error.unknown. Unknown is absent from the
resume blacklists (resumeUnsafeFailureReason, GetLastTaskSession,
GetLastChatTaskSession), so the over-full session stayed pinned as the
resume pointer for the (agent, issue) pair and every later comment on
the issue resumed the same transcript and overflowed again.

Match the CLI copy and the raw stop reason so the failure lands in
agent_error.context_overflow, which those blacklists already exclude —
the next comment then starts from a fresh session instead of replaying
the overflow.

* fix(taskfailure): upgrade an old daemon's catchall on context overflow (MUL-5708)

Installed daemons update on their own cadence, and FailTask only
re-classifies when the caller supplied no reason. A daemon whose rule 1
predates the response-side wordings reports agent_error.unknown, which
is on no resume blacklist — so until every host updates, the over-full
session stays pinned as the (agent, issue) resume pointer and every
later comment replays the same overflow. One un-upgraded host means a
permanently stuck issue, not just a missing label.

Recognise the two witnesses server-side in NormalizeDaemonReason, next
to the MUL-5370 skill-bundle rule it mirrors, so the retirement lands
the moment the server deploys. The accepted legacy set is narrower than
that rule's: only the catchall and the pre-MUL-1949 coarse agent_error.
A refined reason means the old daemon matched an earlier rule on the
same text, which says more about what ended the run than a witness
appearing somewhere in the blob does.

The witnesses move into one shared var so Classify and the normalizer
cannot drift apart.

4fe94a6d40 revert: "MUL-5637 fix(mcp): agent mcp_config is an authoritative allowlist (#6292)" (#6314)
This reverts commit aa349fed02.

Preflight flagged the server/daemon mixed-version gate as a release blocker for
today's v0.4.17 window (MUL-5655): a managed, non-inheriting mcp_config claimed
by a daemon that does not advertise authoritative-mcp-v1 fails the task with
mcp_config_daemon_outdated, and that failure is not auto-retryable. Reverting to
unblock the release; the fix should return once daemon capability coverage in
production is confirmed.

aa349fed02 MUL-5637 fix(mcp): agent mcp_config is an authoritative allowlist (#6292)
* fix(mcp): treat agent mcp_config as an authoritative allowlist

An agent's saved mcp_config was silently widened with the runtime host's
own user-level MCP servers, so an explicitly empty `{"mcpServers":{}}`
resolved to the COMPLETE host set instead of no servers at all — the
opposite of what the operator configured (GitHub #6283).

`--strict-mcp-config` was being passed correctly; the merge happened
before it, in the daemon, so strict mode constrained an already-widened
set. Introduced by #5277 and present in v0.4.16 through main.

Restore the three-state contract in resolveEffectiveMcpConfig:

  null / unset        -> inherit the provider's native MCP configuration
  {"mcpServers":{}}   -> strict empty, no host servers
  non-empty object    -> strict allowlist, exactly those servers

Two explicit inherit paths keep the additive behaviour reachable without
weakening the default:

- runtime_config.mcp.inherit_runtime = true opts an agent back in.
- The claim response now carries mcp_config_overlay_only so the daemon
  can tell an agent-authored config from a per-task Composio overlay.
  Without it, enabling an integration on an agent that never configured
  MCP would have stripped the host servers it was already inheriting.

Both decode paths fail closed: malformed runtime_config never enables
inheritance, and a failed runtime merge falls back to the agent's own
config.

The web MCP tab and the `agent create/update --mcp-config` help text
described the old additive behaviour, which is how a tightened config
could look correct while exposing every host server; both now state
which mode is in effect.

Note for rollout: the fix lives in the daemon, so self-hosted users must
upgrade the daemon — a server/UI upgrade alone does not apply it.

* fix(mcp): close review gaps in the authoritative mcp_config change

Addresses the four must-fix findings from review of #6292.

1. Deleting the last managed server no longer widens access.
   removeManagedMcpServer cleared the config to null, which now means
   "inherit the host's MCP servers" — so a delete took the agent from one
   allowed server to every server on the host. It now leaves an explicit
   `{"mcpServers":{}}`. Restoring inheritance moved to a separate
   clearManagedMcpConfig action behind its own confirmation that states the
   widening. The delete dialog no longer claims "Runtime servers are not
   affected", which was the opposite of the truth.

2. The UI no longer promises a boundary an old daemon does not enforce.
   The strict semantics live in the daemon, so a config saved against an
   older daemon is not yet in effect. Adds the authoritative-mcp-v1 daemon
   capability:

   - The daemon advertises it and reports authoritative_mcp on the
     runtime-capabilities response.
   - The claim path fails closed: a managed, non-inheriting mcp_config
     claimed by a daemon without the capability cancels the task and
     returns 412 with an actionable message, instead of letting that daemon
     merge the host's servers in. runtime_config.mcp.inherit_runtime is the
     documented escape hatch, and it is honest — it declares that the
     operator accepts the host's servers.
   - The MCP tab shows "needs upgrade" rather than "Not exposed" while the
     bound runtime lacks the capability.

3. Saving OpenClaw settings no longer drops the inherit opt-in.
   parseOpenclawRuntimeConfig discarded unknown keys and the tab persisted
   the result as the whole runtime_config, so one unrelated routing save
   silently deleted mcp.inherit_runtime. Unknown keys now round-trip
   through OpenclawRuntimeConfig.passthrough, excluded from the dirty check
   so they cannot make the form look edited.

4. Documents the new semantics in the built-in creating-agents skill and
   its source map: the three states, the persisted
   runtime_config.mcp.inherit_runtime field, and the claim-time capability
   gate.

Also corrects the PR's rollout claim: there is no database migration, but
this does add a persisted JSON field and change the meaning of an existing
one.

* fix(mcp): stop the authoritative-daemon gate from blocking valid claims

CI's backend job failed three handler claim tests with the new 412. Two
distinct problems, both real:

1. The gate fired for a non-object mcp_config. 66 handler fixtures seed
   `[]`, which is not a valid MCP config and cannot carry `mcpServers`, so
   it expresses no boundary to protect. An old daemon does not widen it
   either: mergeRuntimeAndAgentMcpConfig fails to unmarshal a non-object
   and falls back to the agent config alone (verified directly). Gating
   these blocked tasks with no security benefit, so the gate now requires a
   JSON object.

2. The shared daemon test-request helper advertised no capabilities, so
   every claim test was accidentally simulating a pre-#6283 daemon. It now
   defaults authoritative-mcp-v1 on, matching what every current daemon
   sends. Only that capability — skill-bundles / coalesced-comments / rpc
   are feature negotiations whose absence tests real legacy behaviour, so
   they stay opt-in per test.

Adds claim-level coverage for the gate itself, which is what the unit tests
alone could not catch: an outdated daemon gets 412 with an actionable
message and the task is cancelled; a capability-advertising daemon gets
200; the inherit_runtime opt-in lets an outdated daemon through; and an
unmanaged or non-object config is never gated.

Verified against a real migrated schema this time (throwaway Postgres),
which is how the three failures were reproduced locally and confirmed
fixed: `go test ./internal/handler ./internal/daemon` both ok.

* fix(mcp): surface the daemon-upgrade refusal and stop gating safe providers

Addresses the second review round on #6292.

1. The refusal is now visible wherever the operator looks. The default
   claim path is the machine-level BATCH endpoint, which skips build
   failures and still answers 200 {"tasks":[]}, so the previous bare
   CancelTask showed a task that vanished with no stated reason — turning an
   explicit upgrade requirement into an unexplained failure. The claim path
   now fails the task with a new classified reason,
   mcp_config_daemon_outdated, plus the actionable message. That reaches the
   user on all three claim paths and on any daemon version, which a new
   response field could not: the audience is by definition a daemon too old
   to read one. The per-runtime path keeps its 412.

   The reason is deliberately not auto-retryable — the same outdated daemon
   would claim the retry and fail it again.

2. The gate no longer cancels safe tasks. It applied to every provider, but
   only claude / codebuddy / codex / cursor / opencode / openclaw were ever
   merged with host MCP by an old daemon (loadRuntimeMcpServerConfigs).
   Qwen was never merged and already had strict semantics, so its tasks were
   being failed for a risk that does not exist. Scoped via
   providersOldDaemonsMergedRuntimeMcp; an unknown provider does not gate,
   because the gate should only fire where the old behaviour is concrete.

3. The new authoritative_mcp flag now goes through the API schema layer.
   Both local-skills responses were returning raw network JSON, so the flag
   that decides whether the UI may assert an MCP boundary rested on an
   unchecked type assertion. Adds RuntimeLocalSkillListRequestSchema with
   authoritative_mcp and mcp_supported defaulting to FALSE — the fail-closed
   direction — and a MALFORMED_ fallback that cannot express a guarantee.

Claim-level tests now cover all three paths, which is what the previous
helper-only tests missed: per-runtime 412, batch recording the refusal on
the task while still delivering the healthy tasks in the same batch, WS RPC
refusing and accepting, the qwen negative case, the inherit_runtime escape
hatch, and unmanaged / non-object configs.

Verified against a real migrated schema (throwaway Postgres):
go test ./internal/handler ./internal/daemon ./pkg/agent ./pkg/taskfailure
./internal/service all ok.

* fix(mcp): register the new failure reason and wire its copy into the UI

Addresses the third review round on #6292.

1. mcp_config_daemon_outdated was declared but never registered in
   taskfailure.allReasons, so metrics.NormalizeFailureReason missed the
   known-value map and fell through to free-text Classify() — relabelling a
   platform-side refusal as `agent_error.unknown` (verified directly) and
   leaving the Prometheus series un-pre-warmed. Registered it, canonical
   count 22 → 23 (platform 8 → 9), with the wire value and IsAgentError split
   pinned. New test pins the WHOLE canonical set through
   NormalizeFailureReason so forgetting the next reason fails a test instead
   of quietly mislabelling a metric; NormalizeFailureReason had no coverage
   at all before.

2. The upgrade copy was dead. The locale strings landed last round but
   neither consumer mapped the reason: chatFailureCopy fell back to generic
   failure text with the actionable detail buried in the collapsed raw
   error, and task-failure.ts rendered the bare wire value
   `mcp_config_daemon_outdated` in the agent activity list and issue
   execution log. Both are mapped now, with regression tests, plus the
   runtime class pinned in failure-class.test.ts. This directly contradicted
   the claim in the claim-path comment that every path reaches the user, so
   that is now actually true.

3. providersOldDaemonsMergedRuntimeMcp is documented as what it is: a FROZEN
   record of what pre-capability daemons merged, not a mirror of the daemon's
   current provider switch. The old "keep the two lists in lockstep" note was
   actively harmful advice — runtime MCP discovery for a new provider can only
   ship in a daemon that already advertises the capability (never gated), so
   adding it here would fail tasks on old daemons that never merged for it,
   re-creating the qwen false-positive. Pinned with a test.

Also corrects a stale count in task-failure.ts (7 → 9 platform reasons).

Verified against a real migrated schema (throwaway Postgres): full backend
suite green apart from the pre-existing environmental cmd/multica guard; all
9 TestMcpGate_* integration tests pass.

* docs(taskfailure): correct taxonomy counts and finish the reason registration

Non-blocking nits from the fourth review round on #6292.

- Taxonomy counts now say 23 reasons / 9 platform-side. Registering
  mcp_config_daemon_outdated last round updated the assertions but not the
  prose. Swept the whole repo rather than only the flagged lines, which
  turned up four more that were already stale at 21 and drifted further:
  handler/dashboard.go, daemon/poisoned.go, core/types/agent.ts, and the
  db/queries/task_usage.sql comment sqlc copies into the generated file.

  The generated file's comment was updated by hand to match its source.
  Running `sqlc generate` churned 58 lines across 47 unrelated files — the
  local sqlc version differs from the one that produced the checked-in
  output — so that churn was reverted and only the one intended line kept.

- failure_test.go's `required` list now includes
  ReasonMcpConfigDaemonOutdated. Length and label assertions already covered
  the reason, but the list is documented as the complete canonical set, so
  the omission contradicted its own comment.

- Restored the line break in chat-message-list.test.tsx that a previous edit
  of mine collapsed.

Comment, test-fixture and formatting only; no behaviour change.

30318b79bc MUL-5426: fix(daemon): retire sessions whose history the provider refuses to replay (#6083)
* fix(daemon): retire sessions whose history the provider refuses to replay

A run killed mid-reply (machine shutdown, force-quit, SIGKILL) can leave an
empty assistant message in the agent CLI's transcript. Every later resume
replays it, the provider rejects the request, and the (agent, issue) pair is
bricked with no self-healing and no user-facing recovery.

Multica already has the mechanism for this — poisoned-session classification —
but its detector paired "400" with "invalid_request_error", which is the
Anthropic wire shape. The same defect reported by any other provider carried
neither token, so it classified as agent_error.unknown: resume-safe by
omission. GetLastTaskSession kept handing back the dead session on every
follow-up, manual Rerun resolved it through the same predicate, and the
in-turn fresh-session retry never fired because ResumeRejected is false here
(nothing rejected the resume — the transcript loaded and the provider refused
to replay it).

Add taskfailure.UnresumableHistory, which recognises the defect by what the
provider says is wrong — some content is empty, and here is which message in
the history — rather than by status code or provider name. Both signals are
required, so a tool reporting "field must not be empty" does not match.

Wire it into the four places that decide whether a session survives:

- classifyPoisonedError, so the task is written as api_invalid_request
- shouldRetryWithFreshSession, so the turn recovers on all 17 backends
  instead of the subset whose adapter learned to detect it; the tools == 0
  gate is unchanged, so a run that already used a tool is never re-run
- ResumeUnsafeFailure, covering the manual-Rerun path
- both resume queries, as defense-in-depth for hosts whose daemon predates
  this (self-host daemons upgrade on their own cadence)

Fixes #6066. Also covers the daemon half of #5760.

* fix(session): close the Chat and fresh-retry paths that resurrect a poisoned session

Review found the previous commit stopped short in two places, both of which
put the dead transcript back in play.

Chat never consulted the guarded query. The claim handler reads
chat_session.session_id first and only falls back to GetLastChatTaskSession
when it is empty, so a poisoned pointer there bypasses every filter that query
applies. The fail path merely declined to OVERWRITE the pointer, leaving it in
place. It now clears it in the same transaction, matched on session and
runtime so a concurrent turn's newer pointer survives. The promote guard moves
to ResumeUnsafeFailure as well — the reason-only check passed an un-upgraded
daemon's agent_error.unknown row and re-pinned what the clear had just removed.

GetLastChatTaskSession also kept the row-level filter the issue query dropped
in GH #5975: it discarded the newest poisoned row and fell back to an older
completed row carrying the same dead session. It now judges each session by
its latest terminal state, matching GetLastTaskSession.

A recovered turn could not retire anything. A terminal report carried one
session_id, and an empty one meant both "nothing to report" and "forget the
old session", so a fresh-session retry that SUCCEEDED left the id it retried
away from selectable — through an older completed row on the issue, or through
the chat pointer. agent_task_queue.retired_session_id records the abandonment
itself, reported on every terminal path including completed, and both resume
lookups exclude it. This is the contract gap the previous PR deferred; the
fresh-retry path now runs on all backends, so deferring it is not safe.

Also narrows what the cross-backend test claims: it pins the shared decision,
not that all 17 adapters surface the error into Result.Error (#5760 is the
counter-example), and says so.

Co-authored-by: multica-agent <github@multica.ai>

* test(session): require pgx.ErrNoRows in the resume-exclusion assertions

The `if err == nil && prior.SessionID.Valid` form these tests shared is
false-green: any real fault — undefined column, syntax error, dead connection
— makes err non-nil, so the condition is false and the test passes. Run
against a database missing this branch's new column, the exclusion tests
reported PASS on a SQLSTATE 42703, meaning they could not have caught a broken
query.

requireSessionExcluded demands pgx.ErrNoRows specifically and fails loudly on
anything else, so a green run now means the filter worked rather than the
query never ran.

Applied to all nine sites, not just the four this branch added: the other five
guard the same GetLastTaskSession exclusion behaviour that this branch
changes, so leaving them false-green would leave the change under-tested. All
nine pass on a correctly migrated database.

c271f80999 MUL-5370 fix: label stalled skill-bundle downloads, align failure-reason copy with the backend taxonomy (#6001)
* fix(daemon): label stalled skill-bundle downloads and make them retryable

A skill bundle that could not be downloaded during task preparation surfaced
as the bare string "resolve skill bundles: context deadline exceeded".
taskfailure.Classify has no rule for a Go context deadline, so it landed in
agent_error.unknown — a bucket that is NOT on the server's retry allowlist.
A transient stall therefore became a terminal chat failure carrying a label
nobody could act on, and the failure was invisible on the Usage page's Errors
breakdown. (MUL-5370)

- Add the platform-side reason skill_bundle_unavailable and put it on
  retryableReasons. Retrying is cheap and safe: the agent process never
  started, and bundles that did arrive are already cached on disk, so
  successive attempts converge.
- Carry a sentinel error from the resolve loop so the reason is derived
  structurally rather than by matching the wrapped transport error's text,
  and name the skill, its declared size and the elapsed wait in the wrap —
  enough to tell "this bundle is too big for the link" from "the link is
  dead" without reading daemon logs.
- Normalise the wire shape an OLD daemon produces (a non-empty catchall plus
  the previous "resolve skill bundles:" wrapper) on the server side. Installed
  daemons upgrade on their own cadence, and FailTask only classifies when the
  caller supplied nothing, so without this the fix would reach only hosts that
  happened to update — while the un-upgraded hosts most likely to be hitting
  the bug kept failing terminally.
- Teach Classify about "deadline exceeded" and net/http's "Client.Timeout
  exceeded while awaiting" so any other Go-side deadline that reaches it as
  text stops falling into the unknown bucket too.
- Backfill historical rows in both agent_task_queue and chat_message. Scoped
  to agent_error.unknown alone — the old wrapper string postdates the
  in-flight classifier by three weeks, so no row carrying it can hold the
  legacy coarse value — which keeps the down migration an exact inverse.

Co-authored-by: multica-agent <github@multica.ai>

* fix(chat): give chat its own failure copy for the refined reasons

#5991 rebuilt the operator-facing failure labels around an open wire string
with a raw-value fallback, but the chat bubble kept its own exact-key lookup
against the six coarse values from migration 055. So all 14 agent_error.*
values still missed and rendered the generic "Something went wrong and the
agent couldn't finish replying" — the classification the backend had already
computed was discarded at the last step, and that is the message the MUL-5370
reporter saw.

- Add resolveFailureReasonKey in packages/core: exact match, else degrade an
  `agent_error.*` value to its family, else undefined. A reason newer than the
  shipped client now lands on the family line instead of the fallback.
- Rekey the chat copy map by wire value and route it through the helper.
  Chat deliberately degrades to friendly copy rather than adopting the
  operator surfaces' raw-value fallback: it is read by the person who just
  sent a message, and the raw error is one click away under the collapsible.
- Add refined chat copy (en / zh-Hans / ja / ko) only where it can say
  something the family line can't — a different next step: network, auth,
  quota, rate limit, context overflow, missing/outdated CLI, skill download.
- Give skill_bundle_unavailable a label on the web and mobile surfaces and a
  class on the Usage page's Errors breakdown (runtime — the operator response
  is "check the daemon's link to Multica", the provider is not involved).
- Mobile's two label maps were still coarse-only for the same reason; rekey
  them by wire value and fill in the refined taxonomy.

6dba74c3c1 fix(task): auto-retry transient "Connection closed mid-response" like chat (MUL-4910) (#5565)
* fix(task): auto-retry transient provider stream cut like chat (MUL-4910)

Claude Code's "API Error: Connection closed mid-response" is a transient
network cut. In unattended issue runs it fell through to
agent_error.unknown / process_failure — neither in retryableReasons — so
the task terminated. Interactive chat only appeared resilient because the
CLI's own in-process retry usually recovers first; there is no
chat-specific retry in Multica. Both paths share the same
finalizeStreamResult -> Classify -> retryableReasons pipeline.

- classify: route "connection closed" / "mid-response" to
  agent_error.provider_network, before the exit-status rule so the
  "exited with error: exit status N" variant also lands here.
- retry: add provider_network to retryableReasons. It is resume-safe, so
  the retry child inherits the session and continues the truncated
  conversation instead of restarting.

Tests cover the new classification (incl. exit-status variant) and the
retry/resume flags. Note: mirror the substrings into the MUL-1949 offline
backfill SQL to keep in-flight and historical taxonomies aligned.

* feat(task): defer provider_network's final retry ~5s — three-tier (MUL-4910)

Follow-up to the immediate-retry fix: make the connection-closed retry a
three-tier schedule — first run + immediate retry + one retry deferred ~5s —
so a blip that survives the immediate retry gets a short cooldown before the
final attempt instead of firing back-to-back.

Reuses the existing deferred/fire_at primitive (the comment-routing escalation
mechanism) rather than adding new infrastructure: CreateRetryTask gains an
optional fire_at; when set, the child is inserted 'deferred' and the existing
PromoteDueDeferredTasksForRuntime sweeper — already run promote-first on every
claim poll — flips it to 'queued' at fire_at. No migration, no claim-query
change, no daemon change.

- retryAttemptCeiling: raise provider_network's ceiling to 3 (other reasons
  keep max_attempts=2); applied in both retryEligible and
  MaybeRetryFailedTask's budget pre-check so the primary and sweeper paths agree.
- retryDelayForAttempt: only provider_network's final attempt is deferred (5s);
  every other retry — including provider_network's first — stays immediate.
- FailTask + MaybeRetryFailedTask pass fire_at and skip the queued
  broadcast/notify for a deferred child (promotion emits them at fire time).

Timing: the deferred child fires on the first claim poll at/after fire_at, so
>= 5s; on an otherwise-idle runtime it can stretch to the poll interval — the
same behaviour deferred escalations already have.

Tests: pure schedule/eligibility coverage (TestProviderNetworkRetrySchedule)
plus a DB test asserting fire_at controls deferred-vs-queued, attempt=3, and
resume-safety.

* fix(task): persist reason-aware retry budget; respect max_attempts=1 disable (MUL-4910)

Addresses the pre-merge review must-fix: retryAttemptCeiling raised
provider_network to 3 unconditionally, which (1) overrode the
max_attempts=1 "auto-retry disabled" contract and (2) persisted a
self-contradictory child (attempt=3, max_attempts=2) that leaks to the
task API, so a naive attempt < max_attempts consumer would misjudge the
budget.

- retryAttemptCeiling now returns taskMaxAttempts unchanged when it is <= 1
  (disabled stays disabled) and only ever WIDENS otherwise (max(col, 3) for
  provider_network) — a higher configured budget is kept.
- CreateRetryTask takes an optional max_attempts; FailTask and
  MaybeRetryFailedTask write the reason-aware effective ceiling into the
  child so the whole retry chain self-describes (attempt=3, max_attempts=3).
  NULL inherits the parent column, so non-provider_network reasons are
  unchanged.

Tests:
- pure: ceiling widens to 3, keeps a higher budget, and never revives a
  disabled (max_attempts=1) task; eligibility rejects the disabled case.
- DB (end-to-end FailTask): default budget → deferred final child at
  attempt=3/max_attempts=3; first failure → immediate child; max_attempts=1
  → no child. Plus CreateRetryTask persists the passed budget / inherits on NULL.

written with refined values (provider_auth_or_access, context_overflow,
provider_capacity_or_rate_limit, …) at write time rather than waiting on
SQL backfill to re-classify after the fact. PR1 of the Grafana board
plan in MUL-2328 — the upcoming PR2 reuses pkg/taskfailure.AllReasons()
to pre-warm the Prometheus failure_reason label set.

* server/pkg/taskfailure: new package with the canonical 21 Reason
  constants (7 platform-side + 14 agent_error.* sub-reasons),
  AllReasons() returning a defensive copy, IsAgentError() prefix check,
  and Classify(rawError) Reason mirroring the SQL CASE rules from
  MUL-1949 (db-boy's analysis). 100% statement coverage.
* server/internal/daemon/daemon.go: route the 'agent_error' coarse
  fallback paths (StartTask error, runTask early-return error, CompleteTask
  permanent rejection, reportTaskResult default branch) and the
  executeAndDrain default error case (chained after classifyPoisonedError)
  through taskfailure.Classify so blocked / timeout / unknown-status
  results all carry a refined reason on the wire.
* server/internal/service/task.go: FailTask classifies errMsg when the
  daemon-supplied failureReason is empty, eliminating the legacy
  COALESCE(.., 'agent_error') landing.
* server/internal/daemon/poisoned.go: alias FailureReasonIterationLimit
  and FailureReasonAPIInvalidRequest to the canonical taskfailure
  constants. agent_fallback_message and codex_semantic_inactivity are
  pre-existing operational reasons not in the canonical 21 — kept as
  literals for now and revisited in a follow-up PR.

Backfill SQL from MUL-1949 stays as the authoritative offline source of
truth; this PR keeps the in-flight classifier in lock-step with the SQL
CASE expression so historical and future rows share the same taxonomy.
No behavior change for the platform-side reasons (queued_expired,
runtime_offline, runtime_recovery, timeout, etc.) which already align
with the canonical set.
