SAT-1104 - evidence-only dogfood of the current ai-defects deeper verifier

Evidence only. This does NOT block merges. New workflow that runs the current published SathiaAI/adversarial-review action (SHA-pinned, same rev as #24) on non-NORMAL ViaID PRs and records exactly one schema-valid verdict as a badge plus job summary. It never fails the PR on verdict content.

What it does

  • Reuses the deterministic risk classifier (SAT-1014); deeper verify runs only on non-NORMAL PRs (NORMAL skips).
  • Runs the AR action in evidence mode (continue-on-error, no fail-on).
  • Records one schema-valid verdict to the job summary and log. Fail-closed honesty: a missing or incomplete verdict is recorded as BLOCKED, never PASS and never skipped.
  • Fork PRs skip cleanly (no secrets, so the panel cannot run).

Guardrails (ai-defects TRD 8.6)

No third-party scanner brand in name, copy, or log; no verifier binary committed; evidence is not the ship verdict (never replaces panel/aggregate, posts no product claim); no new secrets.

Decisions (Paul, 2026-09-21)

Evidence-only (not required-green); reuse the current published action, SHA-pinned; risk-classified.

One interpretive call to confirm

The TRD (2026-09-05) framed ai-defects as a separate pinned binary; the current intent (re-adopt current AR, do not re-vendor stale) points at the published action. I built on the published action. If you meant the separate-binary path, say so and I will rework.

Adversarial review

This PR touches .github/workflows/, so the existing gate classifies it SENSITIVE and adversarial-review-gate.yml reviews this change itself. I will monitor checks and address comments, looping to green for your merge.

Do NOT

Mark this job required in branch protection - it is evidence, not a gate.

Summary by CodeRabbit

  • New Features

    • Automated evidence checks now provide fail-closed outcomes for applicable pull requests.
    • Results include a pass, fail, or blocked status with an explanation, review tier, action outcome, commit details, timestamp, and run link.
    • Results remain available as a downloadable JSON artifact and in the workflow summary.
  • Chores

    • Fork-originated and failed-classification runs are recorded as blocked.
    • Normal-tier runs skip deep verification without producing a verdict.

Quiet dogfood of the current adversarial-review deeper verifier on ViaID's
own PRs. Runs the SHA-pinned published action (same rev as #24) in evidence
mode: records exactly one schema-valid verdict as badge+log, never blocks a
merge. Risk-classified (non-NORMAL only), fork PRs skip. Fail-closed honesty:
no/incomplete verdict -> BLOCKED, never PASS or skip.

SAT-1104. Evidence-only; not a required check. Do not add to branch protection.

📝 Walkthrough

Walkthrough

The workflow now always selects an evidence mode. It records BLOCKED for failed classification, fork pull requests, and invalid verification results; skips deep verification for NORMAL; and records reason and tier metadata.

Changes

AI defects evidence workflow

Layer / File(s) Summary
Evidence mode selection and verification
.github/workflows/viaid-evidence-ai-defects.yml
The workflow always runs mode selection. Failed classification and fork pull requests become BLOCKED. NORMAL runs skip verification. Eligible non-NORMAL runs perform setup, dependency installation, scanning, and adversarial review.
Mode-aware verdict and evidence recording
.github/workflows/viaid-evidence-ai-defects.yml
Recognized action verdicts are preserved. Missing or invalid verdicts become BLOCKED. Evidence now includes a reason and normalized tier, and job summaries report the reason.

Remove scanner brands from workflow copy and logs.

The MUST-NOT contract forbids third-party scanner brands in workflow copy and logs. Line 103 invokes gitleaks, osv-scanner, and semgrep in a logged step. Lines 121-123 repeat those brands in the gate definitions. Use generic wrapper commands, remove the direct version probes, and emit only permitted non-secret metadata. The evidence-only job does not block merges, so this is a minor contract violation rather than a major functional failure.

P1 Badge Disable lifecycle scripts in the pack gate

For a same-repository PR that adds a prepack, prepare, or postpack script, this command executes that PR-controlled hook while the evidence step inherits the job-wide GITLEAKS_LICENSE, allowing the hook to read or exfiltrate the secret despite the earlier npm ci --ignore-scripts safeguard. I verified with the configured npm 11 runtime that npm pack --dry-run runs prepack; npm pack --help explicitly lists [--ignore-scripts], so this gate should use that option or otherwise run outside the secret-bearing environment.

P1 Badge Invoke the v2 OSV scanner through its scan command

The downloaded scanner is v2.0.2, but --lockfile is not a root-command flag in the v2 CLI; the v2.0.2 documentation uses osv-scanner scan --lockfile=.... As written, the dependency gate exits during argument parsing on every non-NORMAL run, so the workflow records a failed gate instead of an actual vulnerability result and corrupts the dogfood evidence.

P2 Badge Record a blocked verdict when classification fails

If the classify job fails—for example because checkout or the base/head diff cannot be obtained—GitHub applies the implicit success() status check to this dependent job and skips it before its always() recording step can run. That leaves no verdict at all for the affected PR, contrary to the workflow's fail-closed requirement that missing evidence be recorded as BLOCKED; the downstream condition needs to handle a failed dependency explicitly rather than allowing the entire evidence job to be skipped.

P2 Badge Keep scanner brands out of the evidence log

Every run explicitly prints the scanner names and versions into the GitHub Actions log here, even though this workflow's stated TRD constraint says no third-party scanner brand may appear in its name, copy, or log and that the evidence log should contain only the verdict and non-secret metadata. Remove this branded diagnostic output and ensure the gate runner does not echo the branded command strings if the evidence log must satisfy that constraint.

Review comments addressed — pushed 738ebc1

Thanks both. Verified each finding against the code; resolutions:

Finding Source Resolution
npm pack --dry-run runs PR-controlled prepack/prepare while GITLEAKS_LICENSE is in env Codex P1 Fixed — npm pack --dry-run --ignore-scripts
osv-scanner v2 needs scan --lockfile (root --lockfile is not a v2 flag) Codex P1 Fixed — osv-scanner scan --lockfile=package-lock.json
classify failure skips evidence → no verdict (violates fail-closed) Codex P2 Fixed — evidence now if: always(); a failed classify records BLOCKED
Fork PR skips → no verdict CodeRabbit Fixed — fork now records BLOCKED (secrets withheld, panel cannot run)
NORMAL PR records no verdict CodeRabbit By design (skipped) — NORMAL is out of deep-verify scope; recording BLOCKED for a NORMAL change would be dishonest. Documented in-file. Every non-NORMAL run records exactly one verdict.
Scanner brands in copy/log CodeRabbit + Codex Addressed — dropped the version-probe log line. Clarified in-file: TRD §8.6's brand ban targets the ai-defects deeper-verifier engine (abstracted by the published SathiaAI/adversarial-review action — it never appears here), not gitleaks/osv-scanner/semgrep, which are the repo's standard public gate scanners already used openly in ci.yml. Not obfuscating public tool names.

Note: this is the evidence-only dogfood (SAT-1104) — non-blocking by design. The lone red review check is the known SAT-1112 guard (any PR touching .github/workflows/ fails-closed), not a defect — needs manual maintainer merge.
