Root cause

The central Strix gate must reject hollow or incomplete rc=0 scans without turning recovered provider events or scanner-rendered security prose into terminal infrastructure failures.

Two exact consumer counterexamples are now owned here:

  • Inkspan #402@637b910d25dabb363e40d535c6d89f4a5beb8c6d, run 33927906573, job 101234352982, artifact 9967936086: one in-process HTTP 500 replay (attempt 1/5) recovered before a structured successful completion.
  • OriginWeave #166@e84a1a2cc82b1c666218efd441da97849f47b8c2, run 33929688857, job 101237371800, artifact 9968177796: the final current attempt completed successfully with empty SARIF, but ordinary report prose containing “hard-denied first” and “mutations are denied outright” matched the word-anywhere console predicate.

Repair

  • require new, structurally parsed current-attempt completion evidence; recovered transient acceptance additionally requires scan_completed=true, success=true, and well-formed SARIF 2.1.0;
  • preserve raw evidence and allow only the exact recovered in-process transient replay shape with attempt < max;
  • distinguish ambiguous console denied prose from a Denied: control record while keeping warning/fatal console text and report-log signals broadly fail-closed;
  • retain typed provider/timeout handling, exhausted-retry rejection, malformed/stale/incomplete receipt rejection, and source-finding blocking;
  • preserve declared scan scope: Inkspan's 20-file snapshot and OriginWeave's PR snapshot are not full-repository security approvals.

Exact state

  • live base at repair: main@f250638827f8252b0d9e5cb2601f4d333f96162f
  • head: 13fbb48e0b3eeca4ce7d9678add934f9bd87ad3f
  • OriginWeave realistic RED on predecessor 1221b160: expected exit 0, actual exit 1 after the two legitimate report sentences triggered STRIX_PROVIDER_UNAVAILABLE
  • focused OriginWeave GREEN plus provider denied/warning/fatal and exhausted/malformed fail-closed controls: PASS
  • full Strix shell harness: PASS
  • repository suite: 2,890 passed · 1 skipped · 21 subtests
  • bash syntax and diff checks: clean
  • unresolved review threads before this push: 0

Fresh exact-head hosted checks and independent current-head review are required. No predecessor evidence, consumer rerun, self-approval, bypass, force-push, or gate weakening is authorized.

Strix quick-gate previously treated a Strix subprocess that exited 0
without writing any vulnerabilities/*.md report artifact as a clean,
passing scan -- indistinguishable from Strix silently failing to
actually scan anything ("hollow path"). run_strix_once() now calls a
new has_any_strix_vulnerability_report_artifact() guard first on the
rc==0 path and fails closed with a dedicated message when no report
artifact exists; has_only_below_threshold_vulnerabilities() reuses the
same guard instead of its own post-hoc found_any_vuln_file check.

Retrofit ~30 hand-written fake-strix stubs in the ~13k-line test
harness that simulated a successful scan without writing a report
artifact, so the harness matches the new fail-closed contract:

- The large shared case-statement stub in run_gate_case() gets an EXIT
  trap that backstops a default INFO-severity report on any zero exit
  status, reusing (by mtime) the scenario's own latest run directory
  when one already exists instead of creating a competing "latest" dir
  that would shadow it for has_strix_report_failure_signal. The trap
  is signal-aware (ignores SIGTERM/SIGINT) so it does not fire for the
  handful of scenarios that intentionally hang past the fake sleep
  timeout -- "$?" inside a bash EXIT trap is not reliable once the
  triggering foreground command was interrupted by a signal rather
  than completing on its own.
- Ten smaller single-purpose stubs (PR-head-scope, backend-context, and
  Vertex-credential-forwarding cases) get the same EXIT-trap backstop.
- run_pull_request_target_head_scope_case()'s dedicated stub gets the
  same treatment, covering every "*-uses-head-blob" scenario driven
  through it.

Adds a new dedicated regression scenario,
"success-zero-report-artifacts" (both as a direct run_gate_case call
and in the STRIX_TEST_CASE_FILTER fast-dispatch table), whose stub
deliberately exits 0 with no report artifact at all and asserts the
gate now fails closed with the new message -- this is the actual proof
the production fix works, not just fixture repair.

Full harness (bash scripts/ci/test_strix_quick_gate.sh): PASS.
python tests (coverage + interrogate): 2105 passed, 1 skipped, 21
subtests; 100% line/branch coverage on scripts/ci; 100% docstring
coverage.

Fresh exact-head security review requested for 6c101be11ef7b1eb68d2d0e1bf4eaa80b58e743f. Treat missing report artifacts as incomplete evidence, not a clean scan; predecessor #1495 evidence does not transfer.

@opencode-agent fix the unresolved exact-head Devin finding on the existing branch, then re-review the new head. The success proof must be attempt-scoped, not merely any artifact accumulated in ACTIVE_REPORTS_DIR: snapshot the pre-attempt report identity set (or equivalent bounded manifest) before launching Strix and require at least one newly-created, regular, non-symlink vulnerabilities/*.md artifact from that exact invocation before accepting rc == 0. Preserve cumulative prior reports for audit/blocking semantics. Add RED→GREEN coverage where attempt 1 writes a valid nonblocking/retryable artifact then fails, attempt 2 exits 0 with no new artifact, and the gate remains non-passing. Update docs/product-technical-gap-baseline.md with the zero-artifact false-green root cause and attempt-scoped acceptance before merge. Do not weaken finding thresholds or provider-failure fail-closed behavior.

…e-scoped

Devin review on #1495's successor #1563 found a real gap in the "hollow
path" fix: has_any_strix_vulnerability_report_artifact() accepted any
vulnerabilities/*.md artifact from anywhere in the gate run's accumulated
reports directory, so a genuinely hollow rc=0 attempt (its own Strix
invocation wrote nothing) could still pass by riding on an earlier,
already-superseded attempt's leftover evidence -- same-model retry after a
transient error, or a different fallback model tried first. That is exactly
as hollow as the original zero-artifact bug.

capture_attempt_start_vulnerability_files() now snapshots which artifacts
already exist immediately before each run_strix_once() attempt launches
Strix; has_new_strix_vulnerability_report_artifact() replaces the old
pipeline-wide check for both call sites (run_strix_once()'s own rc=0
acceptance and has_only_below_threshold_vulnerabilities()'s presence guard).
Severity scanning for blocking findings deliberately stays cumulative across
every attempt -- a real HIGH/CRITICAL finding from an earlier attempt must
never be silently dropped just because a later attempt didn't reproduce it.

New regression: retry-hollow-second-attempt-fails-closed (attempt one writes
a genuine below-threshold report then fails transiently and retries; attempt
two exits 0 with no new artifact; the gate must still fail closed overall).
Exercising it surfaced a second, harness-only bug: the shared fake-strix
stub's backstop EXIT trap overwrote the same file path when reusing an
existing run directory (deliberate, to avoid shadowing
latest_strix_report_dir()'s mtime selection), which is invisible to
production's now path-keyed attempt tracking -- fixed by picking an unused
path within the reused directory, which required opting the new hollow
regression itself out of the trap (same as success-zero-report-artifacts)
since its whole point is to prove no backstop covers for it.

Also ports the already-diagnosed, already-fixed-elsewhere (.github#1561)
SIGPIPE test flake fix into this branch's copy of the same fixture (a fake
gh --input - receiver that didn't drain stdin before exiting), so it
doesn't intermittently fail this PR's own CI.

Pushed 11b343e3 addressing the Devin finding directly, on this same branch (not a new head):

  • capture_attempt_start_vulnerability_files() snapshots which vulnerabilities/*.md artifacts already exist immediately before each run_strix_once() attempt launches Strix. has_new_strix_vulnerability_report_artifact() replaces the old pipeline-wide has_any_strix_vulnerability_report_artifact() for both call sites (run_strix_once()'s own rc==0 acceptance and has_only_below_threshold_vulnerabilities()'s presence guard) — an attempt is now validated only by evidence it itself contributed, never by a leftover report from an earlier, already-superseded attempt (same-model retry or a prior fallback model).
  • Severity scanning for blocking (HIGH/CRITICAL) findings deliberately stays cumulative/pipeline-wide, unchanged — a real finding from an earlier attempt is never dropped just because a later attempt didn't reproduce it. Provider-failure fail-closed behavior and finding thresholds are untouched.
  • New RED→GREEN regression retry-hollow-second-attempt-fails-closed: attempt one (same model) writes a genuine below-threshold report then fails transiently and retries; attempt two exits 0 with no new artifact. Before this fix that passed (riding on attempt one's leftover evidence); now it fails closed with the same "produced no report artifacts" message.
  • docs/product-technical-gap-baseline.md updated with the root cause and fix (dated entry, ## 2026-09-01 strix_quick_gate.sh: pipeline-scoped artifact presence...).

Full validation: test_strix_quick_gate.sh full harness PASS; coverage run -m pytest tests — 2246 passed, 1 skipped, 21 subtests (the repository-wide 99% coverage shortfall is the pre-existing, unrelated gap independently owned by #1567, confirmed present on vanilla main via git stash).

Re-review exact current head 11b343e30ecb922a475a5e42ae56ce92a17852a3. Verify success evidence is attempt-scoped: each run_strix_once snapshots pre-existing report artifacts and requires a new regular non-symlink vulnerabilities/*.md from that invocation, while severity blocking remains cumulative so an earlier blocking finding cannot disappear. Confirm the prior hollow-success finding is fully closed and the extra test-fixture SIGPIPE repair remains test-only.

Devin Review on #1563 found a second, deeper gap in the round-1
attempt-scoping fix: the pinned strix-agent==1.5.3 only writes
vulnerabilities/*.md when a scan has findings, so a genuinely clean
(zero-finding) scan never writes one -- the fail-closed check would
reject every clean scan, a regression present since #1495 itself.

Verified against the installed strix-agent==1.5.3 package source:
run.json (via write_run_record, status "completed") and
findings.sarif are always written on completion regardless of
finding count; vulnerabilities/*.md is written only when there are
findings.

Switch the success-evidence contract to run.json's completed status,
keeping the same attempt-scoped snapshot-before-launch pattern
(capture_attempt_start_run_records / has_new_completed_strix_run).
Severity scanning for blocking findings stays cumulative over
vulnerabilities/*.md, unchanged.

New regression: success-clean-scan-zero-findings proves a clean scan
with no vulnerabilities/ directory at all now passes.
retry-hollow-second-attempt-fails-closed is re-modeled so attempt one
writes both evidence kinds before failing, proving attempt-scoping
survived the contract switch. Full suite: pytest 2246 passed / 1
skipped / 21 subtests (99% coverage, pre-existing gap owned by
#1567); test_strix_quick_gate.sh full harness: PASS.

Round 2: fixed a deeper Devin Review finding -- clean scans were failing closed too

Pushed c97511e5, on top of the round-1 attempt-scoping fix (11b343e3).

Root cause (verified, not just asserted): I read the actual installed strix-agent==1.5.3 package source (report/writer.py, report/state.py, core/paths.py) rather than trusting the review claim on its face. write_vulnerabilities() writes one vulnerabilities/{id}.md per entry in ReportState.vulnerability_reports, and is only called when that list is non-empty. A genuinely clean, zero-finding scan never writes a vulnerabilities/ directory at all. What ReportState._save_artifacts() always writes on completion, finding count aside, is findings.sarif and run.json (write_run_record, with status set to "completed" by save_run_data(mark_complete=True)).

That means both the original #1495 fix and my round-1 attempt-scoping refinement would fail closed on every clean scan -- the exact false-positive failure mode "hollow success" detection exists to prevent, just triggered by a passing scan instead of a hollow one. This predates round 1; it shipped with #1495.

Fix: switched the success-evidence contract from vulnerabilities/*.md presence to run.json's "status": "completed" field -- Strix's own always-written completion record. Same attempt-scoped snapshot-before-launch pattern as round 1 (capture_attempt_start_run_records() / has_new_completed_strix_run() replace the vulnerabilities/*.md-keyed versions). has_only_below_threshold_vulnerabilities()'s severity scan over vulnerabilities/*.md stays cumulative and unchanged -- a real HIGH/CRITICAL finding from an earlier attempt is still never silently dropped. Finding thresholds and provider-failure fail-closed behavior are unchanged.

New regression, direct proof of the fix: success-clean-scan-zero-findings models a clean scan exactly as strix-agent actually produces one -- a run.json with "status": "completed" and no vulnerabilities/ directory at all -- and asserts the gate now accepts it. retry-hollow-second-attempt-fails-closed was re-modeled to the new contract (attempt one writes both evidence kinds before a transient failure; attempt two exits 0 with no new run.json and still fails closed), proving attempt-scoping survived the contract switch.

Validation: full test_strix_quick_gate.sh harness: PASS. Full pytest: 2246 passed / 1 skipped / 21 subtests (repository-wide 99% coverage is the pre-existing gap independently owned by #1567, unaffected by this change).

Docs: added a round-2 addendum to the existing docs/product-technical-gap-baseline.md dated entry, and extended the CHANGELOG.md [Unreleased] bullet, both describing the contract switch and citing the strix-agent source verification.

Ready for fresh exact-head review.

Keep this security lane non-merge-ready until the latest exact-head evidence contract is tightened. Two current review findings are valid on c97511e5: (1) has_new_completed_strix_run() recognizes completion via regex text search and tracks pre-attempt run.json by path only. Replace that with structural JSON parsing of the top-level status == "completed" and attempt identity based on content/metadata change (for example pre-attempt SHA-256/descriptor snapshot), so an in-place rewritten run.json can count while an unchanged predecessor record cannot. Reject malformed/non-object JSON, symlinks, non-regular files and completion text nested in unrelated fields. (2) The test harness now has large shared EXIT backstops that manufacture run/vulnerability artifacts for unrelated success scenarios. Refactor to a small explicit fake-Strix completion helper that each scenario which models a successful scan invokes deliberately; keep zero-evidence and real zero-finding scenarios explicit and backstop-free. Add regressions for in-place run.json rewrite, nested/forged "status":"completed" text, malformed run record, and unchanged predecessor record. Preserve cumulative prior-attempt vulnerability findings for blocking severity. Refresh docs/product-technical-gap-baseline.md, full Strix harness, 100% owned coverage, and fresh exact-head reviews/checks before auto-merge.

…en completion check

Round 3 of the same Devin Review thread on #1563, in response to two
issues the owner confirmed as valid and blocking:

1. has_only_below_threshold_vulnerabilities()'s presence guard was
   pointed at run.json-based has_new_completed_strix_run() in round
   2, alongside run_strix_once()'s own rc=0 acceptance check. That
   broke every scenario where an attempt's own process later crashed
   non-zero (e.g. a mid-scan ConnectionError) after writing genuine
   below-threshold findings but before reaching a "completed" run
   record -- confirmed as a real CI regression via
   below-threshold-with-connection-error-no-provider and three
   sibling scenarios failing on #1563's own required check.
   Restored has_new_strix_vulnerability_report_artifact() (round 1's
   vulnerabilities/*.md-based, attempt-scoped check) for this call
   site specifically; run_strix_once()'s own rc=0 acceptance keeps
   using run.json-based completion, since that is the one path that
   actually needs proof of a genuinely completed (possibly
   zero-finding) scan.

2. has_new_completed_strix_run() matched "completed" via a plain
   regex over the raw run.json bytes and tracked attempt-start state
   by path only. Rewrote it to shell out to python3 for structural
   JSON parsing (rejects non-JSON, non-object, symlinks, and
   completion text that only appears nested in some other field
   rather than the top-level "status" key) and to content-digest-based
   attempt identity (ATTEMPT_START_RUN_RECORD_DIGESTS, keyed by path
   but compared by SHA-256 of content) instead of path-only
   membership, so a run directory reused in place with genuinely new
   results counts as new evidence while an unchanged predecessor
   record does not.

Severity/blocking-finding scanning stays cumulative and untouched.
Full harness: test_strix_quick_gate.sh PASS.

…io calls

Round 4 of the Devin Review thread on #1495's successor #1563, per the
repo owner's explicit direction: replace the implicit
`trap strix_fake_backstop_vuln_report_on_success EXIT` mechanism
(one shared signal-aware copy plus 11 duplicated ~50-line per-heredoc
copies) with an explicit, deliberately-called helper
(strix_fake_emit_default_success_evidence in the shared case-statement;
a local helper or inline write in each of the 11 standalone scripts)
invoked immediately before exit 0 by every scenario that wants generic
default evidence for an unremarkable successful scan.

76 call sites needed the explicit call added across the shared
~170-scenario case-statement. Scenarios that want no evidence or
genuinely custom evidence (success-zero-report-artifacts,
retry-hollow-second-attempt-fails-closed,
success-clean-scan-zero-findings) simply do not call it, which is now
the unremarkable case rather than a tracked opt-out exception. This
also removes the need to track real signal delivery for the
sleep-based timeout scenarios: a plain sequential call made only on
the path that actually reaches exit 0 cannot run if the process is
killed by SIGTERM first, unlike a trap that fires unconditionally on
any process exit.

New regressions for the production run.json hardening (structural
JSON parsing + content-digest attempt identity, committed separately
as 48a5d02): run-record-in-place-rewrite-counts-as-new-evidence
(positive case -- same path, genuinely new content, after a prior
attempt's transient failure), unchanged-run-record-rewrite-fails-closed
(its exact mirror -- same path, byte-identical content, still fails
closed), forged-nested-completed-status-fails-closed (a run.json whose
top-level status is not "completed" but which contains that literal
text nested under an unrelated field), malformed-run-record-fails-closed
(a run.json that is not valid JSON at all).

Implemented by a worktree-isolated agent per detailed instructions,
then independently re-validated (not just the agent's own report) via
a fresh full harness run and full pytest suite before this commit.

Full suite: pytest 2246 passed / 1 skipped / 21 subtests (99%
coverage, pre-existing gap owned by #1567); test_strix_quick_gate.sh
full harness: PASS (independently confirmed).

Round 3: fixed both confirmed-blocking findings

Pushed 48a5d02e (production regression fix) and 55ba9375 (test-harness backstop-trap refactor), addressing both items from your review comment.

1. Production regression: has_only_below_threshold_vulnerabilities()'s guard was pointed at the wrong evidence contract

Round 2 pointed both run_strix_once()'s rc=0 acceptance and has_only_below_threshold_vulnerabilities()'s presence guard at the new run.json-based has_new_completed_strix_run(). That broke the below-threshold-bypass path: it answers a narrower question than rc=0 acceptance -- "is there genuine severity evidence to trust from the attempt that just concluded, even if that attempt's own process later exited non-zero" (e.g. a real below-threshold INFO finding written just before a mid-scan ConnectionError). A real Strix invocation that crashes after writing partial findings but before its final _save_artifacts() pass may never record status: "completed" at all -- confirmed as a live CI regression via below-threshold-with-connection-error-no-provider and three sibling scenarios failing on this PR's own required check.

Fix: restored has_new_strix_vulnerability_report_artifact() (round 1's vulnerabilities/*.md-based, attempt-scoped check) for that specific call site. run_strix_once()'s own rc=0 acceptance keeps using run.json-based completion.

Also hardened has_new_completed_strix_run() itself per your two informational findings: it now shells out to python3 for structural JSON parsing (rejects non-JSON, non-object JSON, symlinks, and completion text nested in some other field rather than the top-level "status" key) and compares SHA-256 content digests instead of paths alone for attempt identity, so an in-place run.json rewrite with genuinely new content counts as new evidence while an unchanged predecessor record does not.

2. Test harness: implicit backstop trap ... EXIT replaced with explicit per-scenario calls

Per your exact direction, replaced the shared signal-aware trap plus 11 duplicated ~50-line per-heredoc copies with an explicit helper (strix_fake_emit_default_success_evidence()) that every scenario wanting default evidence now calls deliberately, immediately before exit 0 -- 76 call sites across the ~170-scenario case-statement. Scenarios wanting no or custom evidence simply don't call it now, which is the unremarkable case rather than a tracked opt-out list.

Four new regressions for the run.json hardening: run-record-in-place-rewrite-counts-as-new-evidence (positive case), unchanged-run-record-rewrite-fails-closed (its exact mirror), forged-nested-completed-status-fails-closed, malformed-run-record-fails-closed.

This refactor was implemented by a worktree-isolated agent against detailed instructions, then I independently re-validated it myself (full harness re-run, diff spot-checks, full pytest) rather than trusting its self-report alone.

Validation: full test_strix_quick_gate.sh harness: PASS (independently confirmed, not just self-reported). Full pytest 2246 passed / 1 skipped / 21 subtests (99% coverage, pre-existing gap owned by #1567, unaffected).

Docs: docs/product-technical-gap-baseline.md round-3 addendum and CHANGELOG.md both updated with the full root-cause/fix narrative.

Ready for fresh exact-head review.

Devin review round 4 on #1563: has_only_below_threshold_vulnerabilities()'s
presence guard is deliberately not completion-scoped (it must still accept
genuine partial findings from a nonzero-exit crash), but that let it also
rescue an rc=0 attempt run_strix_once() had already determined was hollow
(no completed run record), as long as that same attempt happened to also
write a below-threshold report before failing to record completion.

Add a sticky STRIX_HOLLOW_SUCCESS_DETECTED flag, set in run_strix_once()'s
existing hollow-success branch and reset once per run_current_target_scan()
call alongside the existing INFRA_ERROR_DETECTED/ZERO_FINDINGS_REPORTED
flags (same scope: the below-threshold severity scan is itself cumulative
across the primary attempt and every fallback model). has_only_below_threshold_vulnerabilities()
now checks it and fails closed, mirroring its existing INFRA_ERROR_DETECTED
guard immediately below.

New regression: hollow-success-with-below-threshold-report-fails-closed.

Round 4: fixed the real gap Devin found in round 3's own fix

Merged current main (035269a7) to clear the dirty mergeable state (two straightforward append-only conflicts in CHANGELOG.md and docs/product-technical-gap-baseline.md — both sides' entries kept, no logic conflict).

Then addressed Devin's 🔴 finding: "Incomplete successful scans pass the gate." Round 3 restored has_new_strix_vulnerability_report_artifact() (attempt-scoped vulnerabilities/*.md presence) as has_only_below_threshold_vulnerabilities()'s guard, specifically so a genuine nonzero-exit crash's partial findings aren't lost. Devin correctly pointed out that guard is too permissive in a narrower case it was never meant to cover: an rc=0 attempt run_strix_once() had already determined was hollow (no completed run record) could still be rescued by that same guard if it happened to also write a below-threshold report before failing to record completion — exactly the false-green this gate exists to prevent, just reached through the below-threshold path instead of run_strix_once()'s own direct rc=0 acceptance.

Fix: a sticky STRIX_HOLLOW_SUCCESS_DETECTED flag, set inside run_strix_once()'s existing hollow-success branch, reset once per run_current_target_scan() call alongside the existing INFRA_ERROR_DETECTED/ZERO_FINDINGS_REPORTED flags (same scope, since the below-threshold severity scan is itself cumulative across the primary attempt and every fallback model). has_only_below_threshold_vulnerabilities() now checks it immediately after its existing artifact-presence check and fails closed, mirroring the existing INFRA_ERROR_DETECTED guard directly below it in the same function.

New regression: hollow-success-with-below-threshold-report-fails-closed (fake Strix exits 0, writes a genuine INFO-severity report, never writes run.json — must fail closed, not be rescued by the below-threshold bypass).

Validated:

  • STRIX_TEST_CASE_FILTER=hollow-success-with-below-threshold-report-fails-closed bash scripts/ci/test_strix_quick_gate.sh → PASS
  • Full test_strix_quick_gate.sh shell harness → PASS

  • coverage run -m pytest tests && coverage report → 100% on scripts/ci
  • interrogate → 100% docstrings

Pushed as merge commit abe08620 + fix commit 220ea0e7.

…s flag too

Devin review round 5 on #1563: round 4's STRIX_HOLLOW_SUCCESS_DETECTED
guard only covered has_only_below_threshold_vulnerabilities(). Once that
guard fails, run_current_target_scan() has a second, independent alternate
success path -- evaluate_pull_request_findings(), at both the primary and
fallback-model call sites -- which can set
PR_FINDINGS_DECISION=allow_baseline (an at-or-above-threshold finding
confined to files this PR doesn't change) and let the caller return
success, with no visibility into completion evidence at all.

Gated the return-0 branch after each evaluate_pull_request_findings() call
on the flag too, with an explicit fail-closed return immediately after
(rather than letting a hollow, baseline-allowed attempt fall through into
unrelated downstream logic and hoping it fails there). The function itself
is still always called unconditionally, since the case statement and
fail_unmapped_threshold_report() below depend on PR_FINDINGS_DECISION being
freshly computed for the current attempt.

This exposed a second bug in round 4's own scoping: the flag was reset
once per run_current_target_scan() call, matching the deliberately
cumulative INFRA_ERROR_DETECTED/ZERO_FINDINGS_REPORTED flags -- but
hollow-success is a property of one specific attempt, not the whole scan.
A hollow primary attempt would wrongly taint a genuinely completed
fallback model's own evaluation. Moved the reset to the top of every
run_strix_once() invocation instead, alongside the existing attempt-start
evidence snapshots, so it reflects only the most-recently-concluded
attempt.

New regression: hollow-success-with-baseline-unchanged-report-fails-closed.

Verified: STRIX_TEST_CASE_FILTER=hollow-success-with-baseline-unchanged-report-fails-closed
bash scripts/ci/test_strix_quick_gate.sh -> PASS; full shell harness -> PASS
(also re-confirms round 4's scenario and unrelated
pr-baseline-critical-unchanged/retry-hollow-second-attempt-fails-closed/
success-zero-report-artifacts scenarios still pass under the rescoped
per-attempt flag); PYTHONPATH=. python -m pytest tests -> 2301 passed,
1 skipped, 21 subtests; coverage on scripts/ci -> 100%; interrogate -> 100%.

Stale base resolved — merged current main

Branch was dirty against current main (base recorded here was 8c085835). git fetch origin main && git merge --no-edit conflicted only in scripts/ci/test_strix_quick_gate.sh (.gitignore, CHANGELOG.md, docs/product-technical-gap-baseline.md all auto-merged cleanly — this branch already carries a relatively recent main merge per its own head commit, "resync two exact-head-path-policy assertions with current main"). One real conflict: main's copy of the cron: "30 * * * *" scheduler-heartbeat assertion had a shorter description and no assert_file_not_contains '*/30 * * * *' regression guard, while this PR's own version has both the fuller description and that guard (verified: the guard is not a duplicate — grepped main's full file for the exact assertion string, zero hits). Kept this PR's fuller, strictly-more-thorough version.

Net diff versus current main after the merge: 5 files, 1717 insertions / 11 deletions — matches this PR's own stated scope exactly.

Verified before pushing (head confirmed unchanged at 9d6bb2eb immediately prior):

  • bash -n scripts/ci/test_strix_quick_gate.sh — syntax OK
  • Full suite: coverage run -m pytest tests -q2761 passed, 1 skipped, 21 subtests (excluding the 2 pre-existing Python-3.11-vs-3.12+ sandbox-incompatible files, unrelated to this diff)
  • coverage report --include="scripts/ci/*"100% (12339 statements / 4992 branches)
  • interrogate --fail-under=100 scripts/ci100%
  • git diff --check — clean

Pushed non-force as 9b7c9b80 (two-parent merge commit, 9d6bb2eb..9b7c9b80). Fresh exact-head checks and review are now required per this repo's governance model.

Non-force merge current protected main into #1563. Preserve raw report evidence while allowing only an exact in-process transient replay warning when the same current attempt has new structured terminal success and valid SARIF 2.1.0. Exhausted retries, malformed/stale records, unknown warnings, fatal/denied/timeout signals, and source findings remain fail closed.

Grounded by Inkspan #402 run 33927906573/job 101234352982/artifact 9967936086. Its 20-file PR snapshot is not promoted to full-repository security approval.

Validation: focused recovered/failure cases; complete Strix shell harness PASS; full 2,890 passed, 1 skipped, 21 subtests; bash syntax and diff checks clean.

Exact-head update for 1221b1604e1a6cfde8ca5ab7fd3e93e0fe9faf69 on live base f250638827f8252b0d9e5cb2601f4d333f96162f.

Inkspan consumer evidence was reproduced from run 33927906573, job 101234352982, artifact 9967936086: current report strix-pr-scope-hctgst_8456 has status=completed, scan_results.scan_completed=true, scan_results.success=true, SARIF 2.1.0 results=[], process rc 0, and exactly one recovered strix.core.execution HTTP 500 replay at attempt 1/5. The gate now preserves that raw warning while classifying it as recovered only when the same current attempt supplies new authoritative structured completion. Exhausted 5/5, malformed/stale terminal evidence, unknown warnings, fatal/denied/timeout signals, and real source findings remain fail-closed.

TDD/GREEN: the pre-fix filtered case failed; focused recovered/exhausted/malformed/unknown cases pass; full scripts/ci/test_strix_quick_gate.sh PASS; repository 2,890 passed · 1 skipped · 21 subtests; bash syntax and diff checks clean. The Inkspan scan covered its 20-file changed-source snapshot only and is not represented as full-repository security approval.

Current exact-head hosted checks are fresh but queued and no review evidence is transferred from predecessors. Normal protected merge remains gated.

OriginWeave #166 provenance repair executed on the existing canonical lane.

  • predecessor: 1221b1604e1a6cfde8ca5ab7fd3e93e0fe9faf69
  • new exact head: 13fbb48e0b3eeca4ce7d9678add934f9bd87ad3f (ordinary fast-forward; no force)
  • RED: the realistic final-attempt fixture emitted a structured completed/successful run.json, SARIF 2.1.0 with results=[], process rc 0, and only the two legitimate report sentences (hard-denied first; mutations are denied outright). The predecessor gate returned 1 and classified it as provider unavailable.
  • GREEN: the same fixture now returns 0. A console Denied: control record still fails; warning and fatal console signals still fail; exhausted retries and malformed terminal evidence still fail; unknown warning-class report artifacts, typed provider/timeout failures, stale/incomplete receipts, and blocking findings remain fail-closed.
  • validation: focused discriminating cases PASS; full scripts/ci/test_strix_quick_gate.sh PASS; repository suite 2,890 passed · 1 skipped · 21 subtests; bash -n and git diff --check clean.

OriginWeave, Inkspan, and NewsDOM were not changed or rerun. Fresh hosted checks and independent current-head review are still required; predecessor GREEN is not transferred.

Single-writer claim on existing #1563 only. The previous owner explicitly released at comment 5558038898 and no #1563 worktree command is active.

Scope is bounded to the current-head CodeRabbit review 5124768543 after fresh verification:

  1. fail closed when a recovered-warning console also contains a GitHub ::error:: command;
  2. detect an overwritten vulnerabilities/*.md artifact by content digest, not path alone.

I will ordinary-merge protected main@c232ca03ef891644e5397313b87849cf9e5a25ac so merged #1957/#1959 semantics are retained, add realistic RED/GREEN coverage, run exact-head Strix and repository tests, and push only to the existing fix/strix-fail-closed-on-zero-report-evidence branch. I will not touch .github/workflows/strix.yml, the concurrent changed-scope/admission consolidation, provider/model/timeouts, permissions, or consumer runs.

Merge protected main, retain raw recovered-transient evidence until structured current-attempt classification, preserve terminal ::error:: signals, and bind reused vulnerability report paths to content digests.

Executed repair on the existing canonical #1563 branch; this is not a predecessor acknowledgement.

Exact remote head: bd18909065c5e70211fe79315ddd8e8f8d438c41 (normal non-force descendant; protected main@dd0b96feded94f66ecf59b25a5a9b58cfc8b4f69 is the second parent). The remote tree d541ad69c8622ccdcbfd6a798831885342dd30a7 exactly matches the tested tree.

RED on the pre-fix combined tree:

  • tests/test_strix_attempt_evidence_provenance.py: 2 failed, 2 passed. A rewritten same-path vulnerabilities/*.md was treated as stale, and a recovered-warning receipt containing ::error:: was accepted.
  • Full shell integration then exposed the newly merged fix(strix): sanitize strix-agent's recovered transient replay warning #1959 sanitizer deleting retry warnings before receipt validation: both exhausted attempt 5/5 and malformed terminal evidence scenarios incorrectly exited 0.

Minimal causal repair:

  • snapshot SHA-256 digests for attempt-start vulnerability reports; accept a reused path only when current bytes differ;
  • include GitHub ::error:: in the structured recovered-warning classifier's terminal signals;
  • retain raw replay warnings and let the current-attempt run.json + SARIF classifier decide the narrow recovered exception. Unknown warnings, exhausted retries, malformed/stale receipts, fatal/denied/timeout/error signals, and blocking findings remain fail-closed.

GREEN on the exact remote tree:

  • focused provenance/sanitizer: 11 passed;
  • all Strix Python contracts: 128 passed · 21 subtests;
  • full repository with warnings as errors: 2960 passed · 1 skipped · 21 subtests;
  • bash scripts/ci/test_strix_quick_gate.sh: PASS;
  • bash -n scripts/ci/strix_quick_gate.sh scripts/ci/test_strix_quick_gate.sh: PASS;

Source writer released for #1563 at exact remote head bd18909065c5e70211fe79315ddd8e8f8d438c41.

A fresh detached checkout of that exact commit/tree completed the warnings-as-errors full suite: 2960 passed · 1 skipped · 21 subtests, plus syntax/diff/clean-tree checks. The full Strix shell harness also ended PASS on the identical tree. No local test or source-writing process remains.

Hosted state at release: 5 discovered workflow runs queued, current-head formal reviews/approvals 0, unresolved review threads 0. This is therefore locally GREEN but not merge-ready; no self-approval, bypass, rerun, or merge was attempted. A successor writer must fresh-fetch this head and current protected main before modifying it.

Bring this worktree onto origin/fix/strix-fail-closed-on-zero-report-evidence
(bd18909) without force-pushing. CHANGELOG conflict kept the live PR
wording; the older local hollow-scan bullet was superseded by typed receipts.

Restack onto current main (non-force)

GitHub head is now 92eb0a4e9bde9b600bb020fe507949be4210d1a7 on protected main@7fd571dbcdbae6acf29d8f4ee704d7ba6297e4db.

  • previous published head bd189090 remains an ancestor
  • 0d490831 inherited the live PR head (CHANGELOG kept the published wording)
  • 92eb0a4e merged current main with ort (28 files from main, no Strix-gate conflict)
  • push was a fast-forward bd189090..92eb0a4e (no force-push)
  • unique vs main is still the 7-file Strix fail-closed delta (strix_quick_gate.sh, harness, two pytest modules, CHANGELOG, gap baseline, .gitignore)

Local verification on this exact head

  • focused pytest (attempt evidence / recovered transient / Caido retry / backend-unavailable / CodeQL contracts / merge scheduler): 406 passed
  • bash scripts/ci/test_strix_quick_gate.sh: PASS (exit 0, wall ~4788s)
  • untracked uv.lock was not committed

CodeRabbit notes against older heads (hollow-primary-recovers-via-completed-fallback missing *), path-only vuln artifacts, recovery regex missing ::error::) are already superseded on this tree: the hollow scenario is gone, has_new_strix_vulnerability_report_artifact compares digests, and recovery signals include ::error::.

Fresh exact-head hosted checks and an independent current-head OpenCode/Noema verdict are required. Predecessor job evidence on bd189090 does not transfer. OpenCode missing-verdict, Noema orchestrator/free 502, and CodeQL pending-on-old-head are dispatch/gateway, not a reason to weaken this gate.

SARIF 전체 구조를 검증하십시오.

현재 검증은 version, runs, 각 runresults만 확인합니다. 따라서 tool.driver가 없는 불완전한 SARIF도 recovered completion으로 허용됩니다. 이 결과는 provider 실패 신호를 제외하므로 실패-폐쇄 판정을 우회할 수 있습니다.

SARIF 2.1.0 스키마 검증 또는 동등한 구조 검증을 적용하십시오. tests/test_strix_attempt_evidence_provenance.py에는 tool.driver가 없는 SARIF를 거부하는 회귀 테스트를 추가하십시오.

Exact-head hosted note for 92eb0a4e9bde9b600bb020fe507949be4210d1a7 on protected main@7fd571dbcdbae6acf29d8f4ee704d7ba6297e4db.

Local Strix shell harness on this tree is PASS. Agent Review Runtime Quality CI is SUCCESS. Current CodeQL compatibility shards (101985633186 python, 101985633225 actions) are terminal FAILURE with DISPATCH_OUTCOME=success and VERDICT_STATE=pending after a successful dispatch; that is the required-check settlement chicken-and-egg owned by #1902 / #2040 / #2032, not a Strix SARIF or hollow-report source defect on this delta.

No extra push on this branch while exact-head checks are still in flight (cancel-in-progress would drop them). No predecessor evidence transfer, self-approval, paid bypass, or force-push.

Exact-head hosted Strix on 92eb0a4e9bde9b600bb020fe507949be4210d1a7 job 101985972083 / run 34202086272 is terminal FAILURE before the gate runs.

Sidecar: exited before healthz (status 1); provider_discovery_failed provider=bytez code=http_status_500.
Preflight strix-plain-chat-preflight-v2: ready_count=0, rejected_count=16 (HTTP 429/404/TimeoutError across NVIDIA NIM and OpenRouter free routes). Artifact 10047503386. Pool remained orchestrator/free with priced_selected_count=0.

This is fail-closed free-pool unavailability, not a hollow-report or Strix SARIF source defect on this delta. No paid bypass, extra push, or predecessor-evidence transfer.

Fresh consumer canary for this canonical Strix evidence writer: fast-mlsirm#1773@fa3d06a1a55ecc91e561603d1daf9f2c4de2c348, Strix run/job 34284217353 / 102256794796, artifact 10080622334 (sha256:feb402d0062244db0455c203395ae3b04ab95132f835de70db44f9d94bae620f).

Downloaded artifact evidence is a new shape not covered by the two current PR-body counterexamples:

  • run.json: status=completed, scan_completed=true, success=true.
  • SARIF 2.1.0: zero results.
  • terminal report: no actionable vulnerabilities in the declared two-file PR scope; no narrative/SARIF contradiction observed.
  • report strix.log: exactly one WARNING-level record, strix.tools.web_search.tool: web_search invoked without PERPLEXITY_API_KEY configured; no ERROR/CRITICAL/FATAL line.
  • attempt console also prints Strix's ordinary MODEL QUALITY WARNING because the virtual model name openai/orchestrator/free is not in Strix's hard-coded recommended-model display list.
  • after Penetration test completed / Vulnerabilities 0, protected-main gate still emits the generic report-warning failure and then STRIX_PROVIDER_UNAVAILABLE: contextual-orchestrator/orchestrator/free exhausted.

The same job's trusted sidecar preflight selected 24 free candidates, admitted 6 ready routes, and the gateway chat/completions preflight succeeded on attempt 1 (finish_reason=stop, priced routes 0). Therefore provider exhausted is not a valid diagnosis for this artifact.

This suggests the current #1563 rule that unknown warning/fatal text remains broadly fail-closed needs a typed distinction rather than a broad success carve-out: an auxiliary capability warning (here missing Perplexity web search) may still justify a non-passing/incomplete-capability verdict, but it must not be converted into gateway exhaustion after current-attempt structured completion exists. Central issue #2026 now carries the full exact canary as comment 5594179700.

Please keep raw warning telemetry and fail-closed evidence policy, but add a fixture for completed+consistent structured evidence with an auxiliary-tool warning, alongside genuine exhausted-provider and malformed/inconsistent controls. No leaf/provider fallback change was made.
