+DiskSage Noema jobs `99111099730` and `99110885279` logged
+`request_failed status=413 code=request_too_large` before startup. That line was
+the sidecar's intentional oversized `Content-Length` contract test, not model
+discovery or a provider response. The actual terminal condition was exhaustion
+of the initially selected provider routes before healthz. The contract probe now
+captures and asserts its expected diagnostic without emitting it, while runtime
+preflight tries a maximum of 24 discovered routes in concurrent batches of four
+and stops after the first batch with usable text. Every route still uses the
+ten-second timeout, zero retries, the same plain-chat payload, and sanitized
+evidence; exhausting the bounded batches remains a startup failure.
 The pin includes upstream `#887` (`2591b66`), which fixes the gateway's
 incorrect 1024-character rejection. The same probe sends Strix-shaped function
 tools with 1025-, 1026-, and 2000-character descriptions and verifies that

+## 2026-08-30 Provider-family catalog bound
+
+The 24-route startup budget is a total bound, not a promise to stop after four
+routes from the first provider family. The sidecar now defaults
+`ORCHESTRATOR_CATALOG_FAMILY_CAP` to 24, allowing an OpenRouter-only discovery
+catalog to expose every route within the same bounded preflight budget. An
+operator may still set a lower explicit family cap when outage-domain diversity
+is more important than route breadth; the generic policy CLI retains its
+independent family-cap default.

+## 2026-08-30 Startup and serving timeout separation
+
+The ten-second route timeout is a startup-admission budget: a route that does
+not answer the bounded readiness probe quickly enough is excluded before
+healthz. It must not also bound the real review request. The serving
+`ModelClient` now uses the 120-second transport budget already used by the
+Noema review gate, while retaining zero retries and the same output-token and
+temperature policy. The launcher test constructs both client policies and

test_strix_quick_gate.sh pins an exact contract: the
required-workflow-bootstrap job's "Enforce Cloudflare Pingora edge
policy" step must carry an explicit
`if: ${{ github.event_name == 'pull_request_target' }}` guard. A prior
merge into this branch dropped the line (following a since-superseded
"redundant guard" removal elsewhere), breaking the pinned
exact-head-path-policy contract test on this PR's head. Restore it.

Subject: [PATCH 27/65] fix(ci): coordinate sidecar startup watchdog with
 launcher's real worst case

Devin Review flagged a real bug on this PR's head (2937e520): the sidecar
shell script's health-loop watchdog killed the review sidecar after a fixed
180s, but the launcher's own startup sequence (discovery, then batched
preflight probing) can legitimately need more than that -- a run behaving
correctly, just spending its own allotted budget, was misreported as "sidecar
failed to become healthy" because the two budgets were never actually
coordinated.

Verified against the literal current constants (not Devin's original rough
~105s/~100s estimate) rather than reusing it blindly:
- discover_all_models() worst case: 7 sequential HTTP calls (shared
  models.dev fetch + one per bootstrapped provider credential
  [openai/openrouter/nvidia_nim/nvidia_nim_sub/bytez] + the OpenRouter ZDR
  endpoints fetch) at DISCOVERY_TIMEOUT_SECONDS=15.0s each = 105.0s.
- Batched preflight worst case: ceil(24/4)=6 batches x 2 x 10s = 120s
  (already documented in-code; confirmed still accurate).
- Combined real worst case: 225s -- already over the previous flat 180s
  watchdog on its own, before any headroom.

Fix (option a, single source of truth): the launcher now defines
REVIEW_DISCOVERY_TIMEOUT_SECONDS, REVIEW_DISCOVERY_MAX_SEQUENTIAL_HTTP_CALLS,
REVIEW_DISCOVERY_WORST_CASE_SECONDS, REVIEW_PREFLIGHT_WORST_CASE_SECONDS,
REVIEW_STARTUP_HEADROOM_SECONDS (30s, explicit and justified), and
REVIEW_STARTUP_WATCHDOG_SECONDS = 255 (their sum). The launcher module's
top-level imports are stdlib-only, so contextual_orchestrator_review_sidecar.sh
imports REVIEW_STARTUP_WATCHDOG_SECONDS directly (no vendored dependency
needed yet at that point in the script) instead of hard-coding its own
timeout, so a future change to either phase's budget constants cannot
silently desynchronize the two again. Fail-closed behavior is preserved: a
genuinely stuck process is still killed, just after the correct deadline.

Adds a purely static regression test (no timing simulation, non-flaky in CI)
that recomputes both worst cases independently from the primitive constants,
asserts REVIEW_STARTUP_WATCHDOG_SECONDS covers their sum with non-negative
headroom, locks in the real numbers (105.0 / 120 / 255), and asserts the
shell script actually imports the constant rather than hard-coding "180".
Also updates the existing fallback-escalation worst-case test to compare
against the launcher's own REVIEW_PREFLIGHT_WORST_CASE_SECONDS instead of the
stale bare 180 literal.

Also fixes a smaller doc-accuracy finding from the same review round:
docs/doctoring/contextual-orchestrator-vendored-sidecar.md claimed "any
provider discovery error stops startup," but the launcher actually logs each
provider failure and continues with whatever succeeded, only failing closed
if the resulting eligible-model set is empty -- matching CHANGELOG.md's
already-endorsed "log the failure, continue with whatever succeeded"
description. Prose-only change, no behavior change.

Verification: coverage run -m pytest tests (2099 passed, 1 pre-existing
unrelated failure -- see PR comment); coverage report --show-missing (100%
on scripts/ci, per pyproject.toml); interrogate (100% docstrings); bash -n on
the sidecar script; git diff --check; and the contextual-orchestrator review
launcher/sidecar/policy/live-discovery test files run together (144 passed).

+When one configured provider's discovery call fails, the launcher logs a

+provider's discovery succeeded at all, or none of what did succeed contains a
+general-chat, text-output model matching the selected pool

Subject: [PATCH 28/65] fix(ci): reconcile contradictory Pingora guard
 contracts by removing the redundant guard

My earlier commit 55867cd7 satisfied test_strix_quick_gate.sh's pinned
expectation that the "Enforce Cloudflare Pingora edge policy" step
carry an explicit `if: ${{ github.event_name == 'pull_request_target' }}`
guard, but Devin's review correctly flagged that this directly
contradicts tests/test_pingora_edge_workflow_contract.py, which asserts
the opposite: that exact string must NOT appear in the file at all.

Checked which side is actually correct: opencode-review.yml's *entire*
workflow trigger (`on:`) is exclusively `pull_request_target` with no
other event type, so `github.event_name` is unconditionally
'pull_request_target' for every run of this job. The step-level guard
is therefore provably dead code -- exactly the reasoning behind the
prior "fix(opencode): remove redundant bootstrap event guard" commit
that removed it. That removal was correct; it just never updated this
sibling bash contract, which is why the guard kept getting readded and
re-removed across several branches' independent "fixes" without either
side reconciling with the other.

Revert 55867cd7's guard re-addition and fix the actually-stale contract:
test_strix_quick_gate.sh now asserts the required-workflow-bootstrap job
carries no if: condition at all, matching the deliberate no-redundant-
guard design and tests/test_pingora_edge_workflow_contract.py.

Verified together: bash scripts/ci/test_strix_quick_gate.sh -> PASS;
python -m pytest tests/test_pingora_edge_workflow_contract.py -> 1
passed; full suite -> 2100 passed, 1 skipped, 21 subtests; coverage
100% on scripts/ci; interrogate 100%; git diff --check clean.

Subject: [PATCH 29/65] fix(sidecar): require serving-budget confirmation
 before route admission

Devin Review found a real, live bug on this PR ("Serving-incompatible
routes pass startup", ContextualWisdomLab/.github#1454, previously tracked
in-code as a known-but-unfixed gap): _preflight_review_agents admitted a
candidate the moment its cheap REVIEW_PREFLIGHT_BASE_TOKENS (16) probe
returned any text, without ever confirming that same candidate also serves
the real REVIEW_MAX_OUTPUT_TOKENS (4096) budget _build_model_client uses for
actual review traffic. A route whose provider satisfies a 16-token
completion but rejects or empties out at 4096 passed startup and only
failed once real serving began -- silently defeating the preflight's
purpose.

Fix: a base-probe success no longer admits by itself. It now falls into the
SAME second-attempt path a budget-too-small failure already used (ADR-0005's
escalation retry), drawing from the identical shared, bounded
REVIEW_PREFLIGHT_MAX_ESCALATIONS counter -- there is no new, separate, or
unbounded allowance. Success is recorded `confirmed_at_serving_budget`
(base already worked, this just reconfirms it); a rescued failure keeps the
existing `escalated` label (base failed, this second attempt is what
rescued it). Either way a candidate takes at most one base attempt plus one
more, so REVIEW_PREFLIGHT_WORST_CASE_SECONDS and the derived
REVIEW_STARTUP_WATCHDOG_SECONDS (both already computed independent of how
many candidates in a batch escalate) are unchanged -- verified by the
existing static regression tests, which still pass unmodified.

Added regression coverage for the exact reported scenario (a route that
succeeds at the base probe but fails/rejects at the real serving budget must
not be admitted, both for an empty response and for an outright rejection)
and for the shared escalation budget bounding confirmations the same way it
already bounded escalations. Updated the three existing tests whose
assertions pinned the old (buggy) single-call admission behavior.

Verification: coverage run -m pytest tests (2103 passed, 1 skipped) +
coverage report --show-missing (100% on scripts/ci; the launcher itself is
coverage-omitted per pyproject.toml, exercised via runpy in tests instead),
interrogate (100%), bash -n on the sidecar script, git diff --check, and a
targeted re-run of both
tests/test_contextual_orchestrator_review_runtime_preflight.py (65 passed)
and tests/test_contextual_orchestrator_review_sidecar_contract.py
(29 passed).

+    ways a candidate reaches that confirming probe:
+
+    1. **The base probe already returned usable text.** This is the
+       ordinary, most common case; the second probe exists purely to CONFIRM
+       that same candidate also serves the real budget, not to diagnose a
+       failure. Success marks ``confirmed_at_serving_budget`` (not
+       ``escalated``) on the row -- the base attempt already worked, this
+       second attempt only re-proves it at the real budget.
+    2. **The base probe's response was empty for a "budget too small" reason**
+       -- either ``choices[0].finish_reason == "length"`` (OpenAI's
+       documented signature), or the vendored
+       ``ModelClient._response_content``'s own broader signature (a populated
+       ``message.reasoning`` with no string ``content``, which a reasoning

+       across the pool, and this is the exact original failure mode PR #1436
+       responded to). Success marks ``escalated`` on the row -- the base
+       attempt failed and this second attempt is what actually rescued it.
+
+    Either way, the SAME candidate gets at most one additional attempt (never
+    a third), and that attempt is bounded by one shared
+    ``REVIEW_PREFLIGHT_MAX_ESCALATIONS`` counter -- there is no separate
+    counter for "confirming a success" versus "escalating a failure", since
+    both are the identical "one more attempt at the larger budget" action for

Subject: [PATCH 30/65] fix(sidecar): separate confirmation budget from rescue
 escalation budget

Devin Review flagged a high-severity regression introduced by d9900c1a on
this same PR ("Later healthy routes cannot start",
ContextualWisdomLab/.github#1415): making the serving-budget confirmation
mandatory for every successful base probe, while still spending the SAME
shared REVIEW_PREFLIGHT_MAX_ESCALATIONS counter that was originally sized
only to occasionally rescue a FAILED base probe, meant as few as 4
candidates in the very first batch(es) -- each simply succeeding their base
probe, the ordinary case -- could exhaust that counter's four slots on their
own mandatory confirmations. Every later candidate's confirmation was then
denied by _EscalationBudget.try_reserve() regardless of merit, defeating
batching's entire purpose of evaluating up to 24 routes to find one usable
one.

Confirmation now draws from its own dedicated REVIEW_PREFLIGHT_MAX_CONFIRMATIONS
budget, sized to REVIEW_PREFLIGHT_MAX_TOTAL_ROUTES (24) so even the fully
pessimistic case -- every candidate ever probed in a run succeeds its base
probe -- still gets its confirmation shot. REVIEW_PREFLIGHT_MAX_ESCALATIONS
keeps its original, narrower, smaller rescue-only purpose and cap, untouched.
_preflight_with_fallback shares one instance of each of the two budgets
across its primary/fallback stages, exactly as it already did for the one
budget before this fix. Rejections now distinguish
confirmation_budget_exhausted from escalation_budget_exhausted in evidence.

REVIEW_PREFLIGHT_WORST_CASE_SECONDS/REVIEW_STARTUP_WATCHDOG_SECONDS are
unchanged (120s/255s): each batch's wall-clock worst case was already
computed as its slowest candidate making at most one base plus one second
attempt, independent of either budget's specific cap -- confirmed by
re-deriving both numbers and by the existing
test_startup_watchdog_covers_discovery_plus_preflight_with_headroom /
test_fallback_escalation_budget_is_shared_with_primary_and_bounds_worst_case
regressions passing unmodified.

Added a red-then-green regression
(test_batched_preflight_first_batch_confirmations_do_not_starve_a_later_healthy_route)
reproducing the exact reported scenario against
_preflight_review_agent_batches: verified failing against the pre-fix code
(4 batch-1 candidates each succeed base probe then genuinely fail
confirmation, exhausting the old shared budget; a 5th, batch-2 candidate
that would pass both attempts was wrongly denied with
"no provider route passed"), and passing after the fix. Also rewrote the
now-stale test_base_probe_success_confirmation_shares_the_escalation_budget
into two tests describing the new dedicated-but-still-bounded confirmation
budget.

Also fixes a doc-consistency issue CodeRabbit found in
docs/adr/0003-contextual-orchestrator-vendored-free-zdr.md: several
Decision/Wiring/Consequences passages still described Strix as using
orchestrator/auto in the present tense, contradicting the header and the
2026-08-30 amendment recording Strix's move to orchestrator/free. Annotated
those passages as superseded by the amendment without rewriting the
historical rationale they record.

Full verification: coverage run -m pytest tests (2105 passed, 1 skipped,
100% branch coverage on scripts/ci per pyproject.toml's fail_under=100,
contextual_orchestrator_review_launcher.py is deliberately coverage-omitted
per existing project policy since it only imports under the vendored
sidecar runtime), interrogate (100% docstrings), bash -n on the sidecar

tests) individually in full.

Subject: [PATCH 31/65] fix(sidecar): count wall-clock seconds, not polls, in
 the startup watchdog

Devin Review flagged a real bug on this PR ("Startup watchdog counts polls,
not seconds", ContextualWisdomLab/.github#1415, review comment on
scripts/ci/contextual_orchestrator_review_sidecar.sh line 439): the
healthz-wait loop incremented a plain poll counter `i` once per iteration and
compared *that* to `sidecar_startup_watchdog_seconds`, even though a single
iteration's real wall-clock cost is the `curl --max-time 2` health probe's
own duration (up to 2s) plus the trailing `sleep 1` (up to 3s total) -- not
the 1s the counter implicitly assumed. A health probe that consumes its full
timeout on every poll could let the 255s watchdog run for roughly 765s
(~3x its documented budget) before firing, directly contradicting both the
wall-clock derivation this same PR's earlier fix (b0917a64) established for
REVIEW_STARTUP_WATCHDOG_SECONDS and the comment block immediately above this
code explaining that derivation.

Fix: reset bash's builtin $SECONDS to 0 immediately before the loop and
compare $SECONDS -- real, auto-advancing wall-clock elapsed time, immune to
curl's own per-call cost -- against the deadline instead of the hand-rolled
counter. Updated the two other places the old counter was surfaced (the
watchdog's own failure message context and the successful-startup log line)
to report $SECONDS too, and updated the digit-overflow guard's own comment
that referenced "$i" in prose. The `sleep 1` poll cadence is unchanged; only
the deadline comparison and its reporting changed.

Regression test: added
test_healthz_wait_loop_fires_near_the_wall_clock_deadline_not_a_poll_count
plus a message-format companion test to
tests/test_contextual_orchestrator_review_runtime_preflight.py, following
the existing _run_gateway_retry_loop convention in the same file --
extracting the loop's exact, tracked source (never a hand-copied duplicate)
and driving it via subprocess against a fake, always-failing `curl` that
sleeps longer than 1s per call, with a small configured watchdog. Asserts
the loop fails near the configured wall-clock seconds and strictly below the
poll-counting bound the old code needed. Verified red against the pre-fix
loop text (reverted locally, confirmed both new tests fail -- one by timing,
one by the extraction markers no longer matching) and green after the fix.
Also updated test_sidecar_derives_its_watchdog_from_the_launcher_single_source_of_truth,
which pinned the exact old `[ "$i" -ge ... ]` comparison string, to pin the
new `$SECONDS`-based one and assert the old one is gone.

Full verification: coverage run -m pytest tests (2107 passed, 1 skipped,
100% branch coverage on scripts/ci per pyproject.toml's fail_under=100),
interrogate (100% docstrings), bash -n on the sidecar script, and
git diff --check, all clean.

Subject: [PATCH 32/65] fix: sidecar account-cap default bypass and discovery
 watchdog undercount

Two real bugs Devin's automated review found on this same PR (#1415)
against the just-landed _catalog_account_cap(DEFAULT_ACCOUNT_CAP) fix
and the discovery-budget arithmetic:

1. contextual_orchestrator_review_sidecar.sh still unconditionally
   exported ORCHESTRATOR_CATALOG_ACCOUNT_CAP=8 whenever no operator
   override was set -- a leftover from an earlier CATALOG_FAMILY_CAP=24
   -> CATALOG_ACCOUNT_CAP=8 rename that fixed the variable's name but
   kept the wrong default. Because the shell always exported a concrete
   8 first, _catalog_account_cap(DEFAULT_ACCOUNT_CAP)'s own env-unset
   fallback to 4 could never trigger in production. The shell now
   derives its default from contextual_orchestrator_review_policy's own
   DEFAULT_ACCOUNT_CAP at runtime (same python3 -c pattern already used
   for sidecar_startup_watchdog_seconds), honoring an explicit operator
   override first. Updated the two contract tests pinning the old
   literal and added executable coverage of the real shell derivation
   block (unset/override/empty/malformed cases). ADR-0003 amended to
   record the correction.

2. REVIEW_DISCOVERY_MAX_SEQUENTIAL_HTTP_CALLS = 7 counted only one
   single-attempt call per registered source plus one unconditional
   OpenRouter extra. Re-verified against the vendored
   contextual_orchestrator/model_discovery.py at the pinned
   ORCHESTRATOR_PIN_SHA: the shared Models.dev fetch retries up to 3x,
   each of the five credentialed sources' primary fetch gets a base
   attempt + one retry (2 each), OpenRouter makes two further
   single-attempt calls plus a concurrent free-model endpoint-feed
   round (live-verified: 21 free models today, budgeted 5 rounds of
   headroom), and discover_all_models() makes two trailing global
   calls the old count missed entirely. New total: 22 sequential-call-
   equivalents (3 + 5*2 + 2 + 5 + 2), raising
   REVIEW_DISCOVERY_WORST_CASE_SECONDS to 330s and
   REVIEW_STARTUP_WATCHDOG_SECONDS to 480s. Decomposed the constant into
   named, independently-testable sub-budgets and added a reconstruction
   test that rebuilds the worst case from the enumerated request
   structure rather than re-asserting the module's own arithmetic.

Verification: coverage run -m pytest tests (2129 passed, 1 skipped,
100% coverage on scripts/ci), interrogate (100% docstrings), bash -n
on the touched shell script, git diff --check clean.

 ## [Unreleased]
+- Fix two real bugs Devin's automated review found on this same PR
+  (ContextualWisdomLab/.github#1415) against the just-landed
+  `_catalog_account_cap(DEFAULT_ACCOUNT_CAP)` fix and the discovery-budget
+  arithmetic:
+  1. **Sidecar shell bypassed the policy account-cap default.**
+     `contextual_orchestrator_review_sidecar.sh` still unconditionally

+     `CATALOG_FAMILY_CAP=24` → `CATALOG_ACCOUNT_CAP=8` rename that fixed the
+     variable's name but kept the wrong default value. Because the shell
+     always exported a concrete `8` before the Python launcher ever ran,
+     `_catalog_account_cap(DEFAULT_ACCOUNT_CAP)`'s own env-unset fallback to
+     `4` (`os.environ.get` only falls back when the key is absent) could
+     never actually trigger in production: every real run got a cap of 8,
+     not 4, so two NVIDIA credentials could still jointly occupy up to 16 of
+     the 24 preflight slots between them instead of the intended 8 (4 each).
+     Fixed by deriving the shell's default the same way
+     `sidecar_startup_watchdog_seconds` already derives its own default —
+     reading `contextual_orchestrator_review_policy.DEFAULT_ACCOUNT_CAP` at
+     runtime via a `python3 -c` one-liner — instead of hard-coding a numeric
+     literal; an explicit operator-set `ORCHESTRATOR_CATALOG_ACCOUNT_CAP`
+     still always wins. Updated the contract tests that pinned the old
+     literal (`test_contextual_orchestrator_review_sidecar_contract.py`,
+     `test_contextual_orchestrator_review_runtime_preflight.py`) and added
+     executable coverage that runs the real shell derivation block (not just
+     the Python helper in isolation) for the unset, overridden, empty, and
+     malformed-override cases. `docs/adr/0003-contextual-orchestrator-vendored-free-zdr.md`
+     amended to record the correction so shell, Python, and ADR text agree
+     on one number (4).
+  2. **Startup watchdog's discovery-time budget undercounted known
+     retries.** `REVIEW_DISCOVERY_MAX_SEQUENTIAL_HTTP_CALLS = 7` (feeding
+     `REVIEW_DISCOVERY_WORST_CASE_SECONDS` ≈ 105s and, in turn,
+     `REVIEW_STARTUP_WATCHDOG_SECONDS` ≈ 255s) counted only one
+     single-attempt call per registered source plus one unconditional
+     OpenRouter extra — it never accounted for retries or for calls the
+     pinned `contextual-orchestrator` revision actually makes beyond that.
+     Re-verified line-by-line against the vendored
+     `contextual_orchestrator/model_discovery.py` at the pinned
+     `ORCHESTRATOR_PIN_SHA`: the shared Models.dev fetch retries up to 3
+     times (not 1); each of the sidecar's five credentialed sources' primary
+     listing fetch gets a base attempt plus one transient-failure retry (2
+     each, not 1 — 10 total); OpenRouter alone makes two further
+     single-attempt calls (ZDR endpoints, provider policies) beyond its own
+     listing call, plus one concurrent (≤8-worker thread pool) endpoint-feed
+     round per currently free-priced model (live-verified against
+     OpenRouter's public catalog on 2026-08-31: 21 free models today, i.e. 3
+     rounds; budgeted 5 rounds as documented headroom for catalog growth);
+     and `discover_all_models()` makes two further trailing global calls
+     once per run (a second, non-cached ZDR-endpoints fetch, plus the
+     credits check) that the old count missed entirely. New total: 22
+     sequential-call-equivalents (3 + 5×2 + 2 + 5 + 2), raising
+     `REVIEW_DISCOVERY_WORST_CASE_SECONDS` to 330s and
+     `REVIEW_STARTUP_WATCHDOG_SECONDS` to 480s. The launcher now exposes
+     each sub-count as its own named constant
+     (`REVIEW_DISCOVERY_MODELS_DEV_MAX_ATTEMPTS`,
+     `REVIEW_DISCOVERY_CREDENTIALED_SOURCE_COUNT`,
+     `REVIEW_DISCOVERY_SOURCE_MAX_ATTEMPTS`,
+     `REVIEW_DISCOVERY_OPENROUTER_SINGLE_EXTRA_CALLS`,
+     `REVIEW_DISCOVERY_OPENROUTER_FREE_ENDPOINT_ROUND_CAP`,
+     `REVIEW_DISCOVERY_TRAILING_GLOBAL_CALLS`) rather than one opaque
+     literal, so a new
+     `test_startup_watchdog_covers_a_retry_heavy_discovery_reconstruction`
+     test can independently reconstruct the worst case from the enumerated
+     real request structure — not merely re-assert the module's own
+     arithmetic on its own constants, which would just re-encode the same
+     kind of undercounted assumption this fix corrects.

Subject: [PATCH 33/65] fix(test): sidecar direct-route test must not trip
 substantive-verdict validation

Merging origin/main brought in #1497/#1504's validate_substantive_verdict,
which now requires parseable changed-line evidence and adversarial-probe
data for any formal (non-comment) verdict. This branch's own
test_call_llm_selects_direct_route_for_the_process_local_sidecar used a
placeholder "diff" string with a fake "approve" verdict -- exactly the
shape main's own test_call_llm_rejects_generic_approve_without_changed_line_evidence
now asserts must raise. This test's actual subject is the sidecar
direct-route orchestration mode (asserted via seen["body"]["orchestration"]),
not verdict-schema validation, so switch the fake verdict's decision to
"comment", which short-circuits that unrelated validation entirely.

Full suite: 2147 passed, 1 skipped, 21 subtests passed. 100% coverage on
scripts/ci/. git diff --check clean.

Subject: [PATCH 34/65] fix(noema): eliminate serving-orchestrator retry/judge
 doubling, fix timeout mismatch

Root-caused contextual-orchestrator#946's four consecutive noema-review
TimeoutError failures (worst-case enumerated in contextual-orchestrator#974,
which found the mismatch but was blocked from making this companion change
here due to a permission denial on that session).

Two real bugs in the sidecar's serving orchestrator construction
(scripts/ci/contextual_orchestrator_review_launcher.py), neither present in
the deliberately zero-retry preflight client:

1. TaskOrchestrator's default tool_retry_attempts=1 makes _invoke retry the
   SAME agent once more on a transient failure before failing over --
   doubling worst-case per-agent wall-clock. Set tool_retry_attempts=0.
2. TaskOrchestrator's default policy.realtime_judge=True makes route_once
   issue a SECOND, independent, fully-bounded provider call per candidate
   to judge the first call's answer -- doubling worst-case wall-clock
   again. That judge's quality ledger is meant to steer a long-lived
   process's future routing; this sidecar is a fresh, ephemeral, one-shot
   process serving exactly one review request per CI run, so the learning
   has no opportunity to matter. TaskOrchestrator's constructor has no
   policy override parameter and OrchestrationPolicy is a frozen
   dataclass, so replace the instance attribute directly via
   dataclasses.replace() after construction.

Verified live against the actual vendored contextual_orchestrator package
(not just read): tool_retry_attempts=0 accepted, realtime_judge flips
True->False via dataclasses.replace, and an end-to-end route_once() call
confirms the judge path is skipped ("reason": "single route path") and a
single attempt is accepted.

Also raised noema_review_gate.py's own external client-side read timeout
from a plain, margin-free 120 to a new named CALL_LLM_TIMEOUT_SECONDS=3000,
derived from the enumerated worst case now that both bugs above are fixed:
up to REVIEW_PREFLIGHT_MAX_TOTAL_ROUTES=24 preflight-verified-ready
candidates, each bounded to at most one REVIEW_SERVING_TIMEOUT_SECONDS=120s
attempt, plus overhead margin -- not guessed. The old 120s external timeout
raced the internal 120s per-attempt budget with zero margin and could not
survive even one candidate needing cross-candidate failover.

contextual_orchestrator_review_launcher.py is excluded from this repo's own
coverage gate (imports the vendored package, which this repo's test suite
cannot import) -- verified via py_compile syntax check plus a live smoke
test against the actual installed contextual_orchestrator package instead.

Fixed two existing tests that hardcoded the old timeout=120 literal
(test_call_llm_repairs_one_rejected_changed_line_verdict,
test_noema_public_dns_result_reaches_valid_model_response) to reference
noema.CALL_LLM_TIMEOUT_SECONDS instead, and added a new dedicated
regression test asserting the exact value.

Full suite: 2148 passed, 1 skipped, 21 subtests passed (baseline 2147 + 1
new test). 100% coverage on scripts/ci/. 100% docstrings (interrogate).
git diff --check clean.

 ## [Unreleased]
+- Fix the root cause of `noema-review`'s four consecutive `TimeoutError`
+  failures on `contextual-orchestrator#946` (enumerated in
+  `contextual-orchestrator#974`): the review sidecar's *serving*
+  `TaskOrchestrator` left `tool_retry_attempts` at its default (1, doubling
+  worst-case per-agent wall-clock via a same-agent retry) and
+  `policy.realtime_judge` at its default (`True`, adding a second, fully
+  independent provider call per candidate to judge the first one's answer)
+  — neither tuned to fit inside `noema_review_gate.py`'s external client
+  timeout, unlike the deliberately zero-retry preflight client. Set
+  `tool_retry_attempts=0` and replace the (frozen) `OrchestrationPolicy`
+  with `realtime_judge=False` for the serving orchestrator only — safe here
+  since this sidecar is a fresh, ephemeral, one-shot process per CI run, so
+  the judge's quality-ledger learning (meant to steer a long-lived
+  process's *future* routing) has no opportunity to matter. Also raised
+  `noema_review_gate.py`'s external read timeout from a plain, margin-free
+  `120` to a new `CALL_LLM_TIMEOUT_SECONDS=3000`, derived from the
+  enumerated worst case (up to `REVIEW_PREFLIGHT_MAX_TOTAL_ROUTES`=24
+  preflight-verified-ready candidates, each now bounded to at most one
+  `REVIEW_SERVING_TIMEOUT_SECONDS`=120s attempt) plus overhead margin, not
+  guessed.

Subject: [PATCH 35/65] fix(noema): restore serving quality gate/failover,
 re-derive timeout honestly

Devin's review on this PR (ContextualWisdomLab/.github#1415, "Serving
answers bypass quality validation") correctly flagged that disabling
policy.realtime_judge to cut latency also removed route_once's real-time
gate on the CURRENT answer and its failover to the next candidate on
rejection -- not just future-routing learning, which was the only aspect
the prior fix considered.

Investigating further found tool_retry_attempts=0 was independently wrong
too: it also drives route_once's own outer cross-candidate loop bound
(max_attempts = 1 + min(tool_retry_attempts, MAX_TOOL_RETRY_ATTEMPTS)) down
to 1, so reverting realtime_judge alone would still leave a judge-rejected
answer with nowhere to fail over to.

Restore both TaskOrchestrator defaults untouched (tool_retry_attempts=1,
realtime_judge=True) and re-derive CALL_LLM_TIMEOUT_SECONDS honestly against
that unmodified configuration (3000 -> 23040s, itemized in the constant's
own comment). Add an explicit timeout-minutes: 360 to the noema-review job
so the GitHub-hosted-runner ceiling this derivation reasons about is
self-documented next to the step it bounds.

 ## [Unreleased]
 - Fix the root cause of `noema-review`'s four consecutive `TimeoutError`
   failures on `contextual-orchestrator#946` (enumerated in
-  `contextual-orchestrator#974`): the review sidecar's *serving*
-  `TaskOrchestrator` left `tool_retry_attempts` at its default (1, doubling
-  worst-case per-agent wall-clock via a same-agent retry) and
-  `policy.realtime_judge` at its default (`True`, adding a second, fully
-  independent provider call per candidate to judge the first one's answer)
-  — neither tuned to fit inside `noema_review_gate.py`'s external client
-  timeout, unlike the deliberately zero-retry preflight client. Set
-  `tool_retry_attempts=0` and replace the (frozen) `OrchestrationPolicy`
-  with `realtime_judge=False` for the serving orchestrator only — safe here
-  since this sidecar is a fresh, ephemeral, one-shot process per CI run, so
-  the judge's quality-ledger learning (meant to steer a long-lived
-  process's *future* routing) has no opportunity to matter. Also raised
-  `noema_review_gate.py`'s external read timeout from a plain, margin-free
-  `120` to a new `CALL_LLM_TIMEOUT_SECONDS=3000`, derived from the
-  enumerated worst case (up to `REVIEW_PREFLIGHT_MAX_TOTAL_ROUTES`=24
-  preflight-verified-ready candidates, each now bounded to at most one
-  `REVIEW_SERVING_TIMEOUT_SECONDS`=120s attempt) plus overhead margin, not
-  guessed.
+  `contextual-orchestrator#974`), then correct that fix per Devin's follow-up
+  review on this same PR (ContextualWisdomLab/.github#1415, "Serving answers
+  bypass quality validation"): an initial version set
+  `tool_retry_attempts=0` and replaced the serving `TaskOrchestrator`'s
+  (frozen) `OrchestrationPolicy` with `realtime_judge=False`, reasoning that
+  the judge's quality-ledger learning (meant to steer a long-lived process's
+  *future* routing) had no opportunity to matter for this fresh,
+  one-shot-per-CI-run sidecar. That reasoning was incomplete on two counts:
+  `realtime_judge` also gates acceptance of the *current* answer and drives
+  failover to the next candidate on rejection — a real per-request quality
+  control, not just future-routing learning — and `tool_retry_attempts=0`
+  independently collapsed `route_once`'s own outer cross-candidate loop to a
+  single attempt (`max_attempts = 1 + min(tool_retry_attempts,
+  MAX_TOOL_RETRY_ATTEMPTS)`), so even reverting `realtime_judge` alone would
+  have left a judge-rejected answer with nowhere to fail over to. Both
+  defaults are now left untouched (`tool_retry_attempts=1`,
+  `realtime_judge=True`), fully restoring serving's per-request quality gate
+  and failover. `noema_review_gate.py`'s external read timeout is
+  re-derived honestly against that unmodified configuration: from the
+  previous fix's margin-free `120`, through an intermediate
+  `CALL_LLM_TIMEOUT_SECONDS=3000` (sized for the now-reverted reduced-retry
+  config), to `CALL_LLM_TIMEOUT_SECONDS=23040` — one `_invoke()` call (worker
+  or judge) tries up to `REVIEW_PREFLIGHT_MAX_TOTAL_ROUTES`=24 candidates at
+  up to `1 + min(tool_retry_attempts=1, MAX_TOOL_RETRY_ATTEMPTS=4)=2`
+  attempts each, bounded by `REVIEW_SERVING_TIMEOUT_SECONDS`=120s
+  (24×2×120=5760s); one `route_once()` attempt makes both a worker and a
+  judge `_invoke()` call (5760+5760=11520s); and `route_once`'s own outer
+  loop retries up to `max_attempts`=2 top-level candidates on judge
+  rejection (2×11520=23040s) — not guessed. `noema-review.yml`'s
+  `noema-review` job now also declares an explicit `timeout-minutes: 360`
+  (GitHub-hosted runners' own hard ceiling, unchanged from the implicit
+  default) so that ceiling — smaller than even one 23040s worst case, and
+  the real backstop for the vanishingly rare compound case where
+  `call_llm`'s one-shot verdict-repair retry also hits its own full worst
+  case — is discoverable next to the step it bounds.

Subject: [PATCH 36/65] fix(noema): cap serving candidates so worst case fits
 the job deadline

Devin's follow-up review on ContextualWisdomLab/.github#1415 ("Valid
reviews exceed job deadline") caught that CALL_LLM_TIMEOUT_SECONDS=23040
(384 minutes) already exceeded noema-review.yml's own explicit
timeout-minutes: 360 (21600s) ceiling for a single call -- a client-side
timeout the enclosing job can never actually honor is a false promise,
not a safety margin.

Rather than shrink the timeout below a legitimate multi-candidate,
judge-gated failover's real needs (reintroducing contextual-orchestrator
#946's original bug), cap how many preflight-verified-ready candidates
the serving orchestrator draws from to a new
REVIEW_SERVING_MAX_CANDIDATES=10 -- smaller than preflight's own 24-route
admission-testing depth, but every one of the 10 has already
independently proven it can serve a real request. Re-derive
CALL_LLM_TIMEOUT_SECONDS backwards from the job's own 360-minute ceiling:
9600s per call (10 candidates x 2 attempts x 2 roles x 2 outer attempts x
REVIEW_SERVING_TIMEOUT_SECONDS=120s), so the function's absolute worst
case across both possible calls (19200s) now actually fits inside the
21600s job that enforces it, with real margin.

Subject: [PATCH 37/65] docs(noema): explain why REVIEW_SERVING_MAX_CANDIDATES
 exceeds today's reachable pool

Devin's review on #1415 correctly noted that _preflight_review_agent_batches
returns on the first batch with any viable candidate, so agents is never
larger than REVIEW_PREFLIGHT_BATCH_SIZE=4 in practice -- REVIEW_SERVING_MAX_
CANDIDATES=10 doesn't currently bind. That's deliberate: this cap and
CALL_LLM_TIMEOUT_SECONDS are a job-deadline safety ceiling derived from the
job's own time budget, independent of preflight's own batching strategy.
Coupling them to today's incidental batch size would let a future change to
that early-return behavior silently regrow the real worst case past the
job's 360-minute ceiling again. No behavior change; comment only.

 deadlock finding

Root-caused why .github#1500's opencode-review required check exhausted
its full 90-minute active-dispatch-and-poll window with no verdict:
pr_review_merge_scheduler.py's decide() blocks on ANY unresolved review
thread before it can ever reach dispatch_opencode_review(), and Devin/
CodeRabbit post threads faster than most PRs get them resolved -- making
"at least one unresolved thread" close to the default state for any
actively-reviewed PR. Not fixed in this pass (a safe informational-vs-
actionable classification needs careful, separately-scoped work); tracked
here with a concrete next-increment plan, plus two smaller, related
timeout-robustness gaps stood down on in #1415's own review.

+## 2026-08-31 opencode-review structural deadlock: unresolved threads starve the dispatch that would resolve them
+
+**Root cause found while investigating why `.github#1500`'s `opencode-review` required check exhausted
+its full 90-minute active-dispatch-and-poll window (added by #1497) with no `opencode-agent` verdict.**
+`pr_review_merge_scheduler.py`'s `decide()` has an unconditional early return
+(`scripts/ci/pr_review_merge_scheduler.py:3462-3474`): `if unresolved_thread_count(pr): return
+decide("block", ...)`, before any code path can reach `dispatch_opencode_review()`. That gate long
+predates automated review bots (traced to `ea2b2cc8`, "Queue auto-merge for approved conflicts") and was
+reasonable when it existed: don't auto-merge or re-review while a real conversation is open. It has since
+become a structural deadlock, because `unresolved_thread_count()` counts *every* active, non-outdated
+thread uniformly, regardless of source or severity — including a purely informational, no-action-needed
+Devin/CodeRabbit note on a file `opencode-review`'s own verdict has nothing to do with. Since dispatching
+a fresh `opencode-review` event is the *only* path to a verdict for the required check, and Devin/
+CodeRabbit post threads faster than most PRs get them resolved, "≥1 unresolved thread" is close to the
+default state for any actively-reviewed PR in this repo — confirmed independently on `#1415` (3 open
+threads at the time of check), `#1507` (1), `#1508` (2), `#1509` (4), vs. `#1491` (0, and its
+`opencode-review` check passed normally). `#1504`'s successful `opencode-review` run the same day is a
+positive control proving the #1497 dispatch-and-poll mechanism itself works correctly whenever no
+unresolved thread blocks the scheduler at evaluation time.
+
+**Not fixed in this pass — the classification problem is genuinely hard to get safely right, not a quick
+patch.** The obvious fix (skip the block for "informational-only" threads) needs a way to tell
+"informational" from "actionable" that doesn't rely on fragile text-pattern matching across multiple
+different bots' own emoji/formatting conventions (Devin's 🔴/🟡/🔍/📝, CodeRabbit's own separate severity
+scheme, human reviewers who follow no pattern at all) — exactly the kind of heuristic this org's own
+conventions warn against, and a wrong classification in either direction is dangerous: too permissive
+silently defeats the safety gate for a real unaddressed finding; too conservative changes nothing. A more
+robust design likely needs to key off GitHub's own formal review *state* (only a thread tied to an actual
+`CHANGES_REQUESTED` review should block) rather than any inline comment thread, but confirming
+`reviewThreads` carries that linkage needs its own careful investigation and test coverage before landing
+a change to this security/trust-boundary-relevant scheduler. Tactically unblocked `#1500` and `#1415` by
+resolving their own already-addressed/informational threads (see those PRs' own threads for the specific
+acknowledgments) rather than touching the gate itself. **Next development increment**: a dedicated,
+narrowly-scoped PR against `pr_review_merge_scheduler.py`'s `unresolved_thread_count()` (or a new,
+separate predicate for review-dispatch eligibility distinct from merge eligibility), with regression
+coverage across informational-only, actionable-bot, and human-reviewer-`CHANGES_REQUESTED` thread shapes,
+before any PR is unblocked by classification logic rather than manual resolution.
+
+**Two related, smaller gaps found and stood down on in `.github#1415`'s own review, tracked here rather
+than dropped:**
+- *Streaming responses can defeat a bare socket timeout.* Both `.github#1415`'s preflight ModelClient
+  (`REVIEW_PREFLIGHT_TIMEOUT_SECONDS`) and — independently found on `.github#1509` — `noema_review_gate.py`'s
+  `call_llm` bound each HTTP attempt with a plain per-operation socket `timeout=`, which only bounds time
+  *between* reads, not total attempt duration: a provider trickling data slowly enough (each chunk just
+  under the timeout) could keep one attempt alive far past its nominal budget. `#1509` already built a
+  real deadline-watchdog wrapper (arm a timer, forcibly close the connection past total budget) for the
+  serving side; the preflight side needs the same treatment once that mechanism lands somewhere mergeable,
+  rather than a second, possibly-inconsistent implementation.
+- *Discovery time is unbounded in catalog size.* `.github#1415`'s
+  `REVIEW_DISCOVERY_OPENROUTER_FREE_ENDPOINT_ROUND_CAP` assumes a bounded number of pagination rounds; if
+  OpenRouter's free-model catalog grows past that assumption, discovery can exceed
+  `REVIEW_STARTUP_WATCHDOG_SECONDS` and abort an otherwise-healthy sidecar. Needs either a deadline-based
+  (not round-count-based) bound in the launcher's discovery wrapper, or the vendored contextual-orchestrator
+  package's own OpenRouter discovery client exposing elapsed-time enforcement directly — a real redesign
+  in either case, not a constant tweak, and this exact family of finding has already been through several
+  rounds of patch → new finding on `#1415` without converging.

Subject: [PATCH 40/65] docs(gap-baseline): record required-check dispatch
 starvation pattern

noema-review (#1415), opencode-review (#1500/#1502/#1503), and strix
(#1503) all independently timed out today with the identical shape: a
required check dispatches a repository_dispatch run against main, then
polls for evidence; the dispatched run sat queued (never picked up by a
runner) for well over an hour, so the poller gave up and reported
failure. Documented as an infrastructure capacity question, not a
per-PR code defect.

Subject: [PATCH 41/65] docs(gap-baseline): correct conflated failure-mode
 claim per Devin review

Devin Review correctly flagged that noema-review's failure (job ran,
hit the actual pre-existing #946 timeout bug) was wrongly grouped with
opencode-review's and strix's genuine queue-starvation (dispatched run
never got a runner at all). Split into two distinct, clearly labeled
failure modes rather than one unsupported shared cause.

Subject: [PATCH 42/65] docs(nvidia-nim): mark the OpenCode NIM-priority hotfix
 note rolled back

opencode-review-dispatch.yml's OPENCODE_MODEL_CANDIDATES has held the
single value "contextual-orchestrator/orchestrator/free" since f8823a54
(#1364), with no nvidia-nim/* prefixes anywhere in the workflow or its
embedded opencode.jsonc. docs/nvidia-nim-opencode-hotfix.md still
described the six-model NIM-prefix hotfix as active and was never
updated per its own "delete this note once restored" instruction,
leaving it factually stale for over a month.

Marked the note historical rather than deleting it, per this repo's
"append a dated note, don't rewrite history" convention, and left the
dormant nvidia-nim provider block in opencode.jsonc and its tested
fallback path in run_opencode_review_model_pool.sh untouched -- those
are a deliberate, still-exercised resilience capability
(tests/test_opencode_model_pool_runner.py), not orphaned code, and
removing them is a separate resilience-tradeoff decision. This closes
out the "worth a follow-up doc cleanup" item recorded in
docs/product-technical-gap-baseline.md's 2026-08-31 direct-NIM audit.

No code changed. Full suite: 2148 passed, 1 skipped, 21 subtests;
coverage 100%; interrogate 100%.

Subject: [PATCH 43/65] docs(nvidia-nim): correct two accuracy findings on the
 hotfix-rollback note

Devin Review on #1415 caught two real errors in bf729bdc:

1. CHANGELOG.md attached "over a month ago" to f8823a54 itself (2026-08-27,
   only 4 days before this entry), not to the doc's own staleness window
   (last touched 2026-07-31, which IS about a month). Corrected to state
   each date explicitly instead of a single ambiguous relative phrase.
2. The doc called the dormant nvidia-nim opencode.jsonc provider block "a
   deliberate, still-tested fallback capability" -- overstated, since every
   enabled_providers list this repo renders excludes it and the cited
   run_opencode_review_model_pool.sh tests fake the opencode invocation
   itself, proving only the script's own candidate-handling logic, not that
   the real OpenCode binary would still reach NVIDIA's API with this
   block's current model ids. Reworded to state precisely what is and
   is not verified.

No code changed. Full suite: 2148 passed, 1 skipped, 21 subtests.

-# many preflight-verified-ready candidates the SERVING orchestrator draws
-# from -- a separate, smaller number than preflight's own admission-testing
-# depth above, which exists to find *some* ready route, not to bound serving
-# wall-clock.
-#
-# Solved backwards from the job's own ceiling: noema-review.yml's
-# `timeout-minutes: 360` (21600s) minus this job's other, non-serving steps
-# (materialize the trusted archive, credential/token resolution, visibility
-# lookup, and this file's own REVIEW_STARTUP_WATCHDOG_SECONDS-bounded sidecar
-# provisioning -- generously rounded to 900s/15min of headroom) leaves 20700s
-# for the "Run Noema LLM review" step. That step can invoke call_llm up to
-# twice (the original request plus one one-shot verdict-repair retry;
-# see noema_review_gate.py's call_llm), so each call's own worst case must
-# independently fit in half of that, 10350s, for the pair to always fit.

-# outer_route_once_attempts(2, from route_once's own
-# `max_attempts = 1 + min(tool_retry_attempts=1, MAX_TOOL_RETRY_ATTEMPTS=4)`)

-# call via _realtime_route_judge/_model_judge_verification) x
-# per-agent-attempts(2, the same `1 + min(1,4)` expression bounding
-# _invoke's own same-agent retry) x REVIEW_SERVING_TIMEOUT_SECONDS(120) x
-# this candidate cap: 2 x 2 x 2 x 120 x N = 960N seconds. Solving
-# 960N <= 10350 gives N <= 10.78, so N=10 -- see
-# CALL_LLM_TIMEOUT_SECONDS in noema_review_gate.py for the resulting exact
-# 960 x 10 = 9600s per-call value this produces. Every one of these 10
-# candidates has already independently PASSED preflight's own base probe and
-# serving-budget confirmation (see REVIEW_PREFLIGHT_MAX_ESCALATIONS above),
-# so this is a reduction in serving-time failover depth among
-# already-proven-healthy routes, not a reduction in how thoroughly preflight
-# searches for a usable one.
-#
-# NOTE (Devin Review, "Serving cap exceeds reachable pool"): today,
-# `_preflight_review_agent_batches` returns on the FIRST batch with any
-# viable candidate (`if viable: return viable, {...}` below), so `agents`
-# here is never larger than REVIEW_PREFLIGHT_BATCH_SIZE=4 in practice --
-# this cap of 10 does not currently bind. That is deliberate, not an
-# oversight: this cap and CALL_LLM_TIMEOUT_SECONDS are a job-deadline safety
-# ceiling derived independently of preflight's own batching strategy, not a
-# number chosen to match it. Coupling them would mean any future change to
-# preflight's early-return behavior (e.g. accumulating viable candidates
-# across batches instead of stopping at the first) could silently regrow the
-# real worst case past what the job's 360-minute ceiling allows again,
-# exactly the bug this constant exists to prevent. Sizing this cap from the
-# job's own budget, independent of today's incidental batch size, means it
-# stays correct even if that batching strategy changes.

   correction. No code changed; this closes out the "worth a follow-up doc
   cleanup" item recorded in `docs/product-technical-gap-baseline.md`'s
   2026-08-31 direct-NIM-communication audit entry.
-- Fix the root cause of `noema-review`'s four consecutive `TimeoutError`
-  failures on `contextual-orchestrator#946` (enumerated in
-  `contextual-orchestrator#974`), then correct that fix per Devin's follow-up
-  review on this same PR (ContextualWisdomLab/.github#1415, "Serving answers
-  bypass quality validation"): an initial version set
-  `tool_retry_attempts=0` and replaced the serving `TaskOrchestrator`'s
-  (frozen) `OrchestrationPolicy` with `realtime_judge=False`, reasoning that
-  the judge's quality-ledger learning (meant to steer a long-lived process's
-  *future* routing) had no opportunity to matter for this fresh,
-  one-shot-per-CI-run sidecar. That reasoning was incomplete on two counts:
-  `realtime_judge` also gates acceptance of the *current* answer and drives
-  failover to the next candidate on rejection — a real per-request quality
-  control, not just future-routing learning — and `tool_retry_attempts=0`
-  independently collapsed `route_once`'s own outer cross-candidate loop to a
-  single attempt (`max_attempts = 1 + min(tool_retry_attempts,
-  MAX_TOOL_RETRY_ATTEMPTS)`), so even reverting `realtime_judge` alone would
-  have left a judge-rejected answer with nowhere to fail over to. Both
-  defaults are now left untouched (`tool_retry_attempts=1`,
-  `realtime_judge=True`), fully restoring serving's per-request quality gate
-  and failover. `noema_review_gate.py`'s external read timeout is
-  re-derived honestly against that unmodified configuration: from the
-  previous fix's margin-free `120`, through an intermediate
-  `CALL_LLM_TIMEOUT_SECONDS=3000` (sized for the now-reverted reduced-retry
-  config), to `CALL_LLM_TIMEOUT_SECONDS=23040` — one `_invoke()` call (worker
-  or judge) tries up to `REVIEW_PREFLIGHT_MAX_TOTAL_ROUTES`=24 candidates at
-  up to `1 + min(tool_retry_attempts=1, MAX_TOOL_RETRY_ATTEMPTS=4)=2`
-  attempts each, bounded by `REVIEW_SERVING_TIMEOUT_SECONDS`=120s
-  (24×2×120=5760s); one `route_once()` attempt makes both a worker and a
-  judge `_invoke()` call (5760+5760=11520s); and `route_once`'s own outer
-  loop retries up to `max_attempts`=2 top-level candidates on judge
-  rejection (2×11520=23040s) — not guessed. `noema-review.yml`'s
-  `noema-review` job now also declares an explicit `timeout-minutes: 360`
-  (GitHub-hosted runners' own hard ceiling, unchanged from the implicit
-  default) so that ceiling is discoverable next to the step it bounds.
-
-  Devin's next review round on this same PR ("Valid reviews exceed job
-  deadline") then caught that this was still wrong: `23040`s (384 minutes)
-  already exceeds that same `timeout-minutes: 360` (21600s) ceiling for a
-  *single* call, before even considering the second, one-shot repair call —
-  a client-side timeout the job can never actually honor is not a safety
-  margin, it is a false promise. Rather than shrink the timeout below what a
-  legitimate multi-candidate, judge-gated failover can need (reintroducing
-  #946's original bug), `scripts/ci/contextual_orchestrator_review_launcher.py`
-  now caps how many preflight-verified-ready candidates the *serving*
-  orchestrator draws from to a new `REVIEW_SERVING_MAX_CANDIDATES=10`, a
-  smaller number than preflight's own 24-route admission-testing depth
-  (every one of the 10 has already independently passed preflight's base
-  probe and serving-budget confirmation). Solved backwards from the job's
-  own ceiling (360 minutes, minus ~15 minutes of generously-rounded headroom
-  for the job's other steps, halved so a second repair call independently
-  fits too): `CALL_LLM_TIMEOUT_SECONDS` is now `9600` (10 candidates × 2
-  attempts × 2 roles × 2 outer attempts × `REVIEW_SERVING_TIMEOUT_SECONDS`=
-  120s), so the function's absolute worst case (two calls, 19200s) now
-  actually fits inside the 21600s job that enforces it, with real margin,
-  instead of relying on that job's own kill as an unacknowledged backstop.
+- Remove `noema-review`'s 120-second serving cutoff while preserving the
+  realtime judge. Each candidate job makes one directly pinned request with
+  a 150-minute worker/judge serving budget, a 19,800-second absolute client
+  deadline, and a 335-minute step ceiling. The five-minute gap lets the
+  client deadline exit and preserve the candidate handoff before the step
+  ceiling; each 350-minute job retains another 15 minutes for that handoff.
+  A failed first candidate hands off
+  to one independent fallback job; its preflight excludes the attempted ID
+  before batched probing, then the request pins only the newly selected ID.
+  Drafts, context-free events, and exact-head reviews are successful no-ops
+  before artifacts or model work. These are the enforced values; earlier
+  120-, 3,000-, 9,600-, and 23,040-second values were superseded during this
+  unreleased change and are intentionally not runtime contracts.

Subject: [PATCH 62/65] fix(noema): fail closed on malformed LLM JSON instead
 of crashing (#1507)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

* fix(noema): fail closed on malformed LLM JSON instead of crashing

The required noema-review check on contextual-orchestrator#960 crashed
with an unhandled json.JSONDecodeError inside extract_json_object,
called from call_llm. A truncated or malformed model reply (observed:
"Expecting property name enclosed in double quotes") propagated past
every layer up to the module's `except RuntimeError` guard, which
only catches RuntimeError, so the whole job died with a raw traceback
instead of a readable review-blocked signal.

Convert the json.JSONDecodeError into the same fail-closed
RuntimeError this file already raises for its other "no usable
verdict" cases in call_llm (unsupported decision, missing summary,
malformed finding) -- no new failure path invented, just reusing the
existing one. The message embeds the raw model response, scrubbed of
secrets and bounded to MAX_LLM_RESPONSE_LOG_CHARS, so the job log
still shows why the verdict was unusable. Also make the top-level
__main__ handler print `::error::{exc}` instead of a bare message,
matching this repo's convention in sibling CI gates (e.g.
opencode_review_receipt_gate.py, select_nvidia_nim_model.py).

Adds regression tests reproducing the exact crash signature at both
the extract_json_object unit level and the call_llm integration
level, asserting a clean RuntimeError propagates instead of an
unhandled JSONDecodeError.

* fix(noema): repair malformed verdict JSON once

* fix(ci): bound required-workflow-bootstrap awk extraction to its own job

The exact-head-path-policy quick gate's assertion for the required-workflow
bootstrap job used an awk range pattern
(/^  required-workflow-bootstrap:$/,/^[^ ]/) whose end pattern never matches
because no job key in opencode-review.yml starts at column 0. That swept an
unrelated `if:` line from a different job into the extracted block and
produced a false assertion failure.

Same root cause already diagnosed and fixed on main in #1506; ported the
identical one-line awk fix here since this branch forked before that fix
landed. Uses an explicit state flag so the end pattern is only tested
starting on the line after the start match.

* fix(noema): allow long orchestrated reviews

* fix(noema): stop logging raw LLM output, fail closed on malformed envelopes

Devin Review found two issues in this PR's own prior fail-closed fix:

Security (priority): extract_json_object's malformed-JSON diagnostic
embedded the LLM's raw response, scrubbed only through a finite,
pattern-based regex list (SENSITIVE_DATA_SCRUB_PATTERNS). noema-review.yml
is a pull_request_target workflow with public Actions logs, and an LLM can
echo back or hallucinate a credential in a shape those patterns don't
recognize. No regex allowlist of known secret shapes can close that gap, so
the fix stops trying to: the diagnostic now logs only a content length and
a truncated SHA-256 fingerprint, never the raw or scrubbed text.
MAX_LLM_RESPONSE_LOG_CHARS is removed as unused.

Bug: call_llm parsed the raw HTTP envelope (json.loads + four chained
.get()/[0] accesses) before the try block that feeds the #1504 one-time
repair-retry, so a non-JSON body or a wrong-shaped envelope (non-object
top-level JSON, non-list choices, non-object choices[0]/message, non-string
content) crashed with an unhandled exception before ever reaching the
verdict-JSON repair boundary. New extract_llm_message_content() validates
each step explicitly with isinstance checks (never a broad except, so real
bugs still surface) and now runs inside the existing repair-retry try
block, so a malformed envelope gets the same one repair attempt a
malformed verdict already gets before failing closed.

Regression tests: extended test_extract_json_object_fails_closed_on_malformed_json
to assert an unrecognized-shape credential (and a known-shape one) never
appears in the new diagnostic; added direct branch coverage for every
extract_llm_message_content failure mode plus call_llm integration tests
for the repair-once and exhausted-repair envelope paths.

2151 tests pass; 100% coverage (branch included) and 100% docstring
coverage on scripts/ci/.

* fix(noema): decode non-UTF-8 gateway replies inside the repair boundary

Devin Review's third pass on PR #1507 found one more crash-before-repair
instance in call_llm: response.read().decode("utf-8") ran before the try
block that feeds the one-time schema-repair retry, so a gateway reply
containing invalid UTF-8 bytes raised an unhandled UnicodeDecodeError
instead of getting the same repair-then-fail-closed treatment every other
malformed-envelope shape already gets.

New decode_llm_response_body(raw_bytes) converts a UnicodeDecodeError into
the same bounded RuntimeError call_llm already uses elsewhere, called from
inside the existing repair-retry try block. Per the round-2 security fix,
the diagnostic never embeds the raw response bytes (even the undecodable
fragment) -- only a length and a truncated SHA-256 fingerprint, since a
body containing invalid UTF-8 could still contain a credential-adjacent
byte sequence.

Regression tests: direct unit coverage of decode_llm_response_body (happy
path plus the fail-closed path, asserting no secret-shaped or tail content
leaks into the message), and a call_llm integration test proving one
repair-retry request followed by a clean top-level RuntimeError when both
the first and retry responses contain invalid UTF-8.

Also verified, no code change needed, per this round's two informational
notes: repair recursion stays bounded to one retry (if repair_error: raise
prevents further recursion), and a falsey-but-wrong-shaped envelope field
(choices/message/content) still fails closed one layer down in
extract_json_object even though extract_llm_message_content treats it
leniently as absent.

2154 tests pass; 100% coverage (branch included) and 100% docstring
coverage on scripts/ci/.

* fix(noema-review-gate): surrogatepass the fingerprint hash to avoid UnicodeEncodeError

Devin Review finding: a malformed verdict containing an escaped lone
surrogate makes the fail-closed diagnostic's sha256(...).encode("utf-8")
raise UnicodeEncodeError before the repair-retry path runs, crashing the
required review check instead of failing closed cleanly.

Use errors="surrogatepass" on the encode call so a lone surrogate is
representable, and add a regression test reproducing the exact crash
signature pre-fix.

* fix(test): split gitleaks-flagged UUID literal via fake_secret helper

gitleaks/GHAS flagged tests/test_noema_review_gate.py:187's
unrecognized_shape_secret literal ("3f29e1a7-8b44-4c1d-9e77-2a5f9c001234")
as a Generic API Key. It is a synthetic UUID-shaped fixture -- the test
deliberately uses a credential-shaped value the finite scrub-pattern list
does NOT recognize, to prove extract_json_object still never embeds raw
content in its error message even for an unrecognized secret shape.

Per this repo's own .gitleaksignore policy ("new findings remain
blocking"), the fix is not an allowlist entry but constructing the
literal at runtime, matching this same file's existing fake_secret(*parts)
helper (already used at lines 56-57 for github_pat-shaped fixtures) so
gitleaks' static scanner sees no single matching string literal.

* fix(ci): remove grep -q from test_strix_quick_gate.sh pipeline checks

grep -q exits on first match and closes its end of the pipe; if the
upstream awk is still writing a large block, it gets SIGPIPE (141).
Under `set -o pipefail` that non-zero awk status wins over grep's real
0, so `if pipeline; then` sees the pipeline as failed even though grep
found a genuine match — silently missing e.g. a forbidden `if:` key or
a fenced-diff marker that should have failed the check.

Ports the same-file fix from PR #1506 to this branch's two call sites
(required-workflow-bootstrap job-block check; opencode review
REQUEST_CHANGES fenced-diff check). This branch's awk patterns were
already the corrected job-block-boundary form, so only the grep -q
removal was needed here.

* fix(ci): allowlist superseded historical gitleaks finding on this PR's own commit

gitleaks scans this PR's full commit range (base..head), not just the
current file content at HEAD. Commit 6657eb76 introduced a synthetic
UUID-shaped test fixture as a bare string literal; commit 3f3bb47 (already
on this branch) fixed it by constructing it at runtime via the file's
existing fake_secret(*parts) helper. The fix at HEAD is correct, but the
now-superseded intermediate commit remains reachable in the PR's history,
so gitleaks keeps re-flagging it on every scan of the full range.

Per this repo's own .gitleaksignore convention ("new findings remain
blocking" -- this is not a new finding, it's a historical instance of an
already-fixed one baked into an intermediate commit that can't be edited
without rewriting this PR's history), added a fingerprint entry matching
the file's established format and precedent for exactly this situation.

that description staying in sync with the workflow -- violating this repo's own

* test: pin Noema head-source policy

* fix: resolve workflow-run PR head

* test: add regression coverage for the Noema stale-trigger guard fixes

A concurrent session on this branch landed the same two Devin Review
fixes independently verified here (workflow_run.head_sha reading the
base commit instead of the PR head; case-sensitive expected-head SHA
comparisons rejecting valid uppercase dispatches). This adds
complementary regression tests on top of that already-landed fix:

- tests/test_noema_orchestrator_workflow_contract.py:
  test_workflow_run_expected_head_uses_pull_request_head_not_base_commit
  and test_workflow_run_expected_head_fails_closed_when_pull_requests_is_empty
  prove, with distinct base vs. PR-head SHA values, that EXPECTED_HEAD
  now resolves to the PR head; test_stale_trigger_step_compares_expected_head_case_insensitively
  and test_stale_trigger_step_still_rejects_a_genuinely_different_head
  execute the workflow's own bash step against a fake `gh` to prove the
  case-insensitive comparison without weakening genuine stale detection.
- tests/test_noema_review_gate.py:
  test_uppercase_expected_head_is_not_stale_before_model_work and
  test_uppercase_expected_head_is_not_stale_before_publication cover
  both Python-side comparison sites end-to-end through submit_review.
- scripts/ci/noema_review_gate.py: expand inspect_and_review's docstring
  to record the case-sensitivity rationale.
- docs/product-technical-gap-baseline.md: dated entry recording both
  confirmed findings, root cause, and evidence.

100% coverage (branch included) and 100% docstring coverage on
scripts/ci/; full test suite green.

* fix: cancel closed PR Noema runs

* fix: scope Noema cleanup to closed PR

* fix: canonicalize Noema trigger identity

* fix: restore repo-wide status-filtered scan for Noema close cleanup

A concurrent session (e0f542f) landed a fix for both Devin Review
findings on the cancel-closed-pr-runs job while this session was
building its own; this session's pre-push rebase surfaced it before
push. Its Bug 1 fix (drop the bare head_sha match, select only by the
PR-scoped display_title) is correct and kept as-is.

Its Bug 2 fix swapped the five-status sequential sweep for one
unfiltered snapshot from `actions/workflows/noema-review.yml/runs`.
That endpoint is scoped to workflow files that exist in the target
repository's own tree; noema-review.yml runs against sibling
repositories only through the organization's required-workflow
ruleset and is never itself committed there (README.md's "siblings
call it" section), so the endpoint is not guaranteed to resolve for
the sibling-repository runs this job's cleanup exists for -- its
primary use case, not an edge case. A failure there is caught by the
job's existing fail-open handling, so it would not error; it would
silently no-op cleanup for every sibling repository. strix.yml's
sibling job, solving the identical cross-repo problem, deliberately
uses the repository-wide `/actions/runs` endpoint instead.

Restores that repository-wide, `status`-server-filtered endpoint
(bounding each query to only currently active runs, not this
workflow's entire history -- it is this org's central, highest-volume
review workflow) and replaces the original single sequential sweep
with a bounded multi-pass re-scan: minimum two full passes always (a
run missed by every status query in pass 1 has, by definition,
settled into a checkable status by pass 2), a third only when either
of the first two found something, capped at three total.

Updates e0f542f's own new jq/bash-executing test for the restored
status-filtered query shape, and adds two more of the same kind:
proving a shared head SHA across two different PRs only cancels the
closing PR's run, and proving a run that only becomes visible on a
status's second query is still cancelled. All three were confirmed to
fail against e0f542f alone before passing against this fix.

* fix: allow two-hour OpenCode reviews

* fix: allow long-running orchestrator reviews

* fix(tests): re-pin review-dispatch blob SHA contract after workflow edit

The pinned REVIEW_DISPATCH_BLOB_SHA in
tests/test_pr_review_autofix_nvidia_nim_contract.py was left stale after a
concurrent commit changed .github/workflows/opencode-review-dispatch.yml's
run-timeout, breaking
test_review_dispatch_blob_sha_stays_paired_with_trusted_workflow (required
'quality' check). Updated the pin to the file's current git blob SHA.

* docs: name the reviewed blob contract

* fix: wait for multi-hour OpenCode verdicts

* fix: widen opencode-review required-verdict poller past its downstream budget

Devin Review found the "Fail closed without a current-head OpenCode verdict"
poller's 639 sleeps x 30s = 319.5 minutes of patience was less than
opencode-review-dispatch.yml's own opencode-review-target job's 325-minute
timeout-minutes budget, before even counting the dispatch/queueing delay and
the validate-pr-metadata -> coverage-source-tree -> coverage-evidence chain
that job's needs: requires first. CodeRabbit separately found the loop's
sleep calls were the only budgeted time -- the gh api --paginate calls
themselves had no timeout and could silently consume unaccounted-for time.

Investigating the full pipeline surfaced a platform ceiling neither
finding's fix could fully absorb: GitHub-hosted runners hard-cap every job's
wall-clock at 360 minutes regardless of timeout-minutes, so no poller budget
can reach the realistic ~415-430 minute worst case (upstream chain plus the
downstream job's own 325m). This fix maximizes patience within that ceiling
and documents the residual gap rather than silently leaving it unaddressed:

- Raise the poller's attempts from 640 to 661 (330m of pure-sleep patience,
  5m past the downstream job's own budget) and the enclosing job's
  timeout-minutes from 325 to 355 (5m under the 360m hard cap).
- Wrap the gh api --paginate call in `timeout 25` so one hung or heavily
  paginated call can't consume unbudgeted time; a failed/timed-out call now
  degrades to "no verdict yet" and keeps polling instead of crashing the
  step under set -euo pipefail.
- Replace the regression test's hard-coded literal assertions (640, 325)
  with ones that parse both workflows' live numbers and assert the budget
  inequalities directly, so a future edit that breaks the relationship
  fails the test instead of only an edit that changes the literal.
  Verified the new tests actually catch the original bug by temporarily
  reverting to the pre-fix numbers.
- Document the residual worst-case gap (2026-08-31 entry,
  docs/product-technical-gap-baseline.md): fully covering the realistic
  worst case needs an architecture change (splitting the wait across
  multiple short-lived dispatches) out of scope for this budget-sizing fix.

* fix: cover complete OpenCode review window

* security: bound external review resource use

* fix: check live PR head before Noema's repair-retry LLM call

CodeRabbit review on #1507: call_llm's one-time repair-retry request fired
unconditionally after a malformed first verdict, with no check that the PR
head hadn't moved since the first attempt started. inspect_and_review
already checks expected_head before model work and before publication, but
a head move mid-first-attempt could still burn a second, potentially
multi-hour NOEMA_LLM_TIMEOUT_SECONDS call for a verdict the existing
post-call check would discard anyway.

call_llm now takes expected_head and, on the repair-retry path only, re-
fetches the live PR via the existing fetch_pr helper and compares its
headRefOid (lowercased, matching inspect_and_review's existing comparisons)
before firing the retry. A mismatch raises the new
StaleHeadDuringRepairRetryError, which inspect_and_review catches and
treats as a clean skip (return 0), consistent with its other two
stale-head checks rather than a hard failure.

Adds regression tests for the skip-on-stale-head path, the unchanged
repair-on-matching-head path, and inspect_and_review's clean handling of
the new exception. Updates every existing call_llm(...) call site for the
new required parameter.

scripts/ci/test_strix_quick_gate.sh) that required-workflow-bootstrap must

The isinstance(candidate, dict) check's False arm is unreachable by JSON
grammar (a successful raw_decode starting at '{' can only yield a dict),
exactly as this function's own docstring already documents. It had no
coverage pragma, so the 100%-branch-coverage gate (fail_under=100) was
failing on this pre-existing, structurally-dead branch. Added
'# pragma: no branch' with a short inline explanation, matching this
repo's existing convention of documenting genuinely unreachable code
rather than fabricating an impossible test case for it.

* fix(ci): remove unreachable Noema JSON branch

* fix: guard Noema supersession's live-head re-check against transient failure

The directional cancellation guard (run IDs smaller than the current run,
plus a fresh live-head re-check immediately before each cancellation) added
to noema-review.yml's "Cancel superseded Noema runs after live-head
validation" step closed a real TOCTOU race, but its new live-head re-check
was itself an unguarded `gh api` command substitution under this step's own
`set -euo pipefail`. A transient failure on that one ancillary call (rate
limit, network blip) would exit the whole step non-zero, failing the entire
noema-review job and blocking a perfectly valid, live-head Noema review over
a housekeeping hiccup unrelated to the review itself (Devin review on

Wrap the re-check the same way every other `gh api` call in this file
already is: on failure, log a warning and exit 0 rather than propagate the
failure. Treat "cannot verify" the same as "verified stale" -- stop
cancelling further runs, but let the job, and the actual review later in
it, proceed.

Adds test_superseded_cleanup_survives_a_transient_live_head_lookup_failure,
executing the real production bash against a fake `gh` that fails only the
live-head lookup, and extends the structural concurrency test with a
docstring enumerating the four invariants this mechanism now holds together
across the multiple review rounds it took to land, plus assertions pinning
the step's pull_request_target-only gate and the now-guarded re-check.

* docs: align Noema coverage evidence

* fix(ci): reject nested Noema JSON recovery

* docs(noema): document RecursionError handling as defense-in-depth

Investigated the review-thread concern that the RecursionError-handling
regression test is synthetic (monkeypatches raw_decode) rather than using a
real deep payload, and that a real payload was previously shown accepted
without raising on the hosted Python 3.14 runner (job 99642234627, commit
ec23350e: "DID NOT RAISE RuntimeError").

Verified independently:
- A real depth = max(20_000, sys.getrecursionlimit() * 2) nested-array
  payload does raise RecursionError on Python 3.11-3.13, but is decoded
  successfully (no exception) by the C-accelerated scanner on Python 3.14.7,
  confirming the hosted-runner evidence. No real payload reproduces the
  condition on this job's own runtime, so the test's monkeypatch is the
  correct choice, not a workaround.
- RecursionError is a RuntimeError subclass, so call_llm's existing
  `except RuntimeError` (already wrapping extract_json_object and every
  post-decode field check, including the decision/summary/findings reads
  the thread also asked about) already converted an unhandled
  RecursionError into the same clean fail-closed exit before this branch
  existed. The explicit `except RecursionError` clause is defense-in-depth
  for a bounded, scrubbed, fingerprinted diagnostic — not a different
  fail-closed outcome.

Documents both points in extract_json_object's docstring and the test's
docstring so a future reader does not mistake the synthetic test for
evidence of an always-reproducible crash.

* fix(ci): pass github.event.action through env in opencode-review.yml

CodeRabbit nitpick on PR #1507: two run: blocks in the required-workflow
bootstrap job still interpolated ${{ github.event.action }} directly into
their shell scripts instead of threading it through env: first, unlike the
pattern this same file already uses at line 38 and 222. Match the existing
convention at the two remaining sites (the "Wait for a current-head OpenCode
verdict" and "Fail closed without a current-head OpenCode verdict" steps).

* fix(ci): bound Noema JSON nesting depth explicitly, independent of raw_decode

Review follow-up (seonghobae, PR #1507): the recursion-handling fix
(aee49c69/b53b0b16) proved only that a raised RecursionError from
json.JSONDecoder.raw_decode is converted to the same bounded diagnostic —
it did not prove real excessive nesting fails closed on this job's own
runtime. Verified: a real depth = max(20_000, sys.getrecursionlimit() * 2)
nested-array payload does raise RecursionError on Python 3.11-3.13, but
decodes successfully with no exception at all on the Python 3.14 hosted
runner this job actually runs on (job 99642234627, commit ec23350e:
"DID NOT RAISE RuntimeError" against that exact real payload). Relying on
raw_decode's own recursion behavior made the fail-closed guarantee a
property of whichever CPython version happens to run the job, not of this
function.

Adds an explicit, string-literal-aware bracket-depth scan
(_json_nesting_within_bound, MAX_JSON_NESTING_DEPTH = 100 -- generously
above the verdict schema's real ~5-level maximum) that runs before
raw_decode is ever attempted, so the bound holds deterministically
regardless of interpreter recursion behavior. The residual
`except RecursionError` clause stays as defense-in-depth for whatever lies
within the bound.

Restores the excessive-nesting regression to a real deep payload (not a
monkeypatch) now that this bound makes the real case reproducible
everywhere; keeps the synthetic RecursionError-from-the-decoder test as
supplemental coverage per review request. Adds a within-bound acceptance
test and an escaped-quote-inside-a-string test (the latter exercises the
scanner's escape handling, which a real deep-nesting payload alone does
not reach).

Also corrects the PR description's stale claim that the RuntimeError
message embeds a scrubbed, length-bounded copy of the raw model response
(the MAX_LLM_RESPONSE_LOG_CHARS constant it named no longer exists);
current source logs only a length and SHA-256 fingerprint, never raw
content -- flagged in the same review comment.

* fix(ci): track array nesting in Noema JSON candidate discovery

Review follow-up (seonghobae, PR #1507, current-head "fail-open blocker"):
extract_json_object's top-level-candidate discovery pass (added in
fb1b118 "reject nested Noema JSON recovery") tracked nesting depth via
{/} only, not [/]. So a malformed outer *array* wrapper containing a
complete, valid inner object -- e.g. '[{"decision":"comment",...}' with
a missing closing ] -- let the inner { be seen at depth zero and
wrongly treated as a fresh top-level candidate, "recovering" a verdict
out of genuinely malformed JSON. This is the same class of bug
fb1b118 fixed for a malformed outer *object* wrapper, just not covering
arrays. depth now increments/decrements across both {/} and [/] so a {
is a candidate only when truly unwrapped by any container.

Also fixes a test-quality bug CodeRabbit flagged in the same review
round: test_noema_superseded_cleanup_selects_only_other_heads_of_same_pr
passed the jq selector's $current as a string via --arg, but the
production invocation (.github/workflows/noema-review.yml) passes it as
a number via --argjson. jq ranks every number below every string, so
the selector's directional `.id < $current` guard was vacuously true
for every fixture row regardless of actual id values -- the test's
assertion held only because the other (name/PR/head) guards still
narrowed correctly, not because the directional guard was exercised.
Restoring the correct numeric type surfaced that the fixture's ids were
also unrealistic (the "current" run had a lower id than the "old"
sibling it should supersede, backward from GitHub's monotonically
increasing run ids); corrected the fixture so "current" has the
highest id, matching real semantics and this repo's sibling
bash-executed test (test_superseded_cleanup_preserves_current_and_newer_run_ids)
that already covers the directional guard correctly.

* fix(ci): validate the referenced wake run on head_sha, not display_title

Devin Review on #1507 flagged the "Wake exact-head required OpenCode
workflow" step's selector as unable to match any run, reasoning that
pull_request_target's reported head_sha is the trusted base revision
rather than the PR head. Verified directly against this org's live
GitHub API data (both ContextualWisdomLab/.github's own PRs and a
sibling repo, noema, consuming the workflow via the org required-
workflow ruleset): head_sha is in fact the PR's actual head commit in
both cases, not the base -- that part of the finding's premise does
not hold, and scripts/ci's own collect_current_head_strix_workflow_runs
already relies on this same, correct, working head_sha semantics.

A concurrent session's prior commit on this branch (bind review wake
to required run) already fixed how the run is *found* -- threading the
triggering run's own $GITHUB_RUN_ID through the repository_dispatch
payload as required_run_id instead of searching by field -- but its
post-fetch *validation* of that run kept the same broken checks the
original selector used: `workflow_url | contains("/actions/
required_workflows/")` and `display_title == "Required OpenCode Review
{repo}#{pr}@{sha}"`. Verified empirically (live REST API queries against
both contexts): `name`/`display_title` only carry that rendered
run-name when opencode-review.yml fires as a native pull_request_target
trigger on its own defining repo; on a sibling repo consuming it
through the required-workflow ruleset -- this repo's actual central-hub
use case -- both fields collapse to the bare workflow name / plain PR
title with no PR or head embedded, while `workflow_url` only contains
"/actions/required_workflows/" in that same ruleset case. No real run
ever satisfies both checks at once, so validation always rejected the
correctly-referenced run regardless of context.

Replace the validation with head_sha exact-match (mirroring the Strix
helper's proven pattern) alongside the existing id/event/path checks.
Updates the contract test's pinned assertions and adds direct jq-level
regression coverage (mirroring this file's existing runtime_verdict
pattern) proving: the referenced run is matched using only id/event/
path/head_sha, with no reliance on name or display_title; a referenced
run whose head_sha has since moved on (Devin Review's "another PR or
head" concern, now reinterpreted for an id-based reference: a
superseded run or a stale/forged required_run_id) is rejected; and a
referenced run for a different required workflow (Strix) is rejected.
The existing end-to-end fake-GitHub script test is updated to a
realistic ruleset-shaped fixture (no PR/head in name or display_title)
proving the real success path doesn't depend on either field. Also
re-pins REVIEW_DISPATCH_BLOB_SHA to match the edited dispatch workflow.

* fix: preserve immutable required review identity

* fix(ci): make Noema JSON nesting a bracket-type-aware stack, not a counter

Devin review on PR #1507's current head: extract_json_object's candidate
discovery and _json_nesting_within_bound both tracked nesting via a plain
depth counter that incremented on any of {/[ and decremented on any of
}/], regardless of matching type. A mismatched closer -- a stray ] where
the enclosing container is a {, or vice versa -- decremented the shared
counter anyway, so it could prematurely signal "the outer wrapper is
closed" while genuinely deeper or still-open structure followed.
Reproduced directly: '{"broken": ]{"decision":"comment","summary":"ok",
"findings":[]}' (a } expected after "broken": but a ] appears instead)
made the naive counter return to zero at that ], so the inner recovery
object's own { was wrongly treated as a fresh top-level candidate and
"recovered" out of genuinely malformed JSON -- the same fail-open bug
59eda8b closed for array wrappers, reopened via bracket-type confusion.

Both functions now use a bracket-type stack (push "{"/"[' on open, pop
only on a matching close; a mismatched closer is a no-op, never popping).
Removed a related dead branch this exposed: _json_nesting_within_bound is
only ever called with text[start] == "{" (its own documented contract),
so the stack's bottom element is always "{" and can never be emptied by
a "]" -- only "}" can legitimately signal completion.

Full suite: 2186 passed, 1 skipped, 21 subtests. 100% statement/branch
coverage, 100% docstrings.

* fix(ci): abort Noema JSON candidate discovery on any structural mismatch

Devin review follow-up on 7df533e: making a mismatched closer a stack
no-op (ignored, not popped) closes the specific case Devin first
reported, but not the general one. A LATER, otherwise-well-formed
bracket pair can still legitimately re-close the stack down to empty
despite an earlier mismatch, so a subsequent { would again look like a
fresh top-level candidate. Reproduced: '[} ] {"decision":"comment",...}'
-- the stray } is correctly a no-op against the open [, but the
following ] still validly closes that [ (matching type), and the {
after it was then wrongly treated as a fresh top-level candidate and
"recovered" out of genuinely malformed JSON.

Both } and ] handlers now break out of candidate discovery entirely the
moment they see a closer that cannot legally match the innermost open
bracket (nothing open, or the innermost open bracket is the other
type), rather than merely no-opping and continuing to scan. Any
closer this malformed anywhere in the response is now treated as proof
the whole response cannot be trusted to contain a clean top-level
object from that point on, not just proof that one bracket group
failed to close.

Signed-off-by: Seongho Bae <me@seonghobae.me>

* test: cover status context pagination guards

* fix(ci): fix sibling Noema cleanup evasion and scheduler wake gaps

Devin Review findings on PR #1507:

- "Sibling Noema runs evade cancellation": noema-review.yml's close and
  live-head-supersession cleanup jobs matched runs only by an exact
  `.name ==` filter and a display_title prefix carrying this workflow's
  rendered run-name. GitHub does not consistently render that run-name for
  an organization-required-workflow pull_request_target run materialized
  in a sibling repository (confirmed live against real contextual-orchestrator
  and noema runs during this fix) -- both fields can collapse to the bare
  workflow name and the plain PR title there, so neither cleanup sweep ever
  matched a sibling PR's runs. Both selectors now additionally match via
  GitHub's own pull_requests[] array (reliably populated here because this
  job only processes same-repository, non-fork PRs) and pin workflow
  identity via the run object's own `.path` instead of `.name`. The
  live-head exclusion in the supersession step is reinforced with a direct
  `.head_sha` comparison alongside the existing display_title-based one.

- "Older review run remains blocking": matching_actions_run_id selected the
  first predicate match scanning the rollup in reverse, which is only the
  newest match when GitHub happens to return contexts chronologically --
  not guaranteed. Now ranks every match with the same check_run_recency_key
  signal used elsewhere in this file to resolve reruns.

- "Large check rollups never wake": the GraphQL rollup fragment caps at 100
  contexts, so a PR with more already-accumulated checks can push the real
  Required OpenCode Review run past that page. dispatch_opencode_review now
  falls back to discover_opencode_required_run_id, a bounded REST lookup
  scoped server-side to the exact event, workflow path, and head SHA.

* fix: preserve live Noema review after cancelled trigger

* fix(scheduler): treat sole head-adopting repository_dispatch run as current

Devin Review finding on PR #1507 ("Live-head reviews retain stale identity"):
a run dispatched for a supplied head can have its validate-pr-metadata step
adopt a live head that advanced after dispatch (the #1533 warn-and-proceed
path) and review it end-to-end, while the run's immutable run-name/
display_title still renders the stale supplied head. active_review_run_refs
was comparing that stale title against the live PR head to decide current
vs. stale, so a scheduler pass could misclassify and force-cancel a review
that was correctly reviewing the live head, then dispatch duplicate work.

Fix: only fall back to the per-title-head comparison when two or more
repository_dispatch runs match the same target-repo/PR-number title prefix
(a genuine overlap -- most plausibly the workflow's own cancel-in-progress
concurrency group not having finished cancelling an actually-superseded run
yet). A sole match is always current, since that same concurrency group
guarantees there is no other run to prefer over it.

+    unhandled exception and crash the review job. Only top-level brace groups
+    are candidates: a ``{`` is a candidate only while a bracket-type stack
+    (tracking ``{``/``[`` opens against their own matching ``}``/``]``
+    closes) is empty, so a valid nested object cannot escape a malformed
+    outer *object or array* wrapper. Every candidate starts at a ``{``,
+    making each successful parse a JSON object (``dict``); only the decode
+    failure itself needs converting. Once a top-level candidate begins, a
+    decode failure rejects the response rather than scanning forward to a
+    later verdict; multiple objects remain supported only when the first
+    candidate decodes successfully.
+
+    A closer that cannot legally match the innermost open bracket — nothing
+    open at all, or the innermost open bracket is the other type — stops
+    candidate discovery outright instead of being a no-op on the stack. Only
+    ignoring the mismatch (popping nothing, but continuing to scan) is not
+    enough: a *later*, otherwise-well-formed ``[``/``]`` or ``{``/``}`` pair
+    can still legitimately re-close the stack down to empty despite the
+    earlier mismatch, so a subsequent ``{`` would again be seen as a fresh
+    top-level candidate even though the response as a whole was never
+    cleanly-formed JSON (Devin review on PR #1507, e.g. ``[} ] {...}``: the
+    stray ``}`` is a no-op, but the following ``]`` still validly closes the
+    ``[``, and the ``{`` after that would wrongly look top-level again). Any
+    closer this malformed anywhere in the response is treated as proof the
+    whole response cannot be trusted to contain a clean top-level object
+    from that point on, not just proof that one bracket group failed to
+    close.
+
+    The raised diagnostic never embeds the raw (or scrubbed) model response.
+    This is a ``pull_request_target`` workflow whose Actions logs are public
+    on this org's public repos, and ``scrub_sensitive_data`` is a finite,
+    pattern-based scrubber: an LLM can echo back or hallucinate a credential
+    in a shape none of its patterns recognize (mid-sentence, base64-wrapped,
+    or simply a shape nobody anticipated). A regex allowlist of known secret
+    *shapes* cannot be a complete defense, so instead of trying to perfect
+    it, the raw content is never logged at all. Only a length and a SHA-256
+    content fingerprint are logged — enough to correlate repeat failures for
+    the same underlying (unlogged) response without exposing its bytes.
+
+    Excessive nesting is rejected by an explicit ``_json_nesting_within_bound``
+    check against ``MAX_JSON_NESTING_DEPTH`` (100 — generously above the
+    verdict schema's own real maximum of roughly 5 levels: object ->
+    ``findings``/``reviewed_lines``/``adversarial_validation.probes`` ->
+    each list's object entries), evaluated *before* ``raw_decode`` is ever
+    attempted, rather than by trusting ``json.JSONDecoder``'s own recursion
+    behavior to raise on deep input. That behavior is not a stable contract:
+    a real ``depth = max(20_000, sys.getrecursionlimit() * 2)`` nested-array
+    payload raises ``RecursionError`` from the C-accelerated scanner on
+    Python 3.11-3.13, but is decoded successfully (no exception at all) on
+    the Python 3.14.7 hosted runner this job actually runs on (job
+    99642234627, commit ``ec23350e``:
+    ``test_extract_json_object_fails_closed_on_excessive_nesting`` failed
+    with "DID NOT RAISE RuntimeError" against that exact real payload).
+    Relying on ``RecursionError`` alone would make this fail-closed guarantee
+    a property of whichever CPython version happens to run the job, not of
+    this function. The explicit bound removes that dependency; a residual
+    ``except RecursionError`` is kept only as defense-in-depth for whatever
+    lies within the bound (``RecursionError`` is itself a ``RuntimeError``
+    subclass, so even an unhandled one here would already surface through
+    ``call_llm``'s own ``except RuntimeError`` around this call and every
+    post-decode field read).
