Conflicting signals: waivers, weak-evidence flag, contradiction detection (3.3.0) - #7
Conversation
Three verified defects in how evidence was treated: - an unresolvable critical made the phase gate impossible, rewarding fake fixes; .prod-audit-waivers.json records a dated, evidenced human acceptance that expires after 180 days and is printed in every report - a category whose only pass was a grep hit could score 100 and be written up as a clean win; categories now carry has_weak_evidence - conflicting signals were invisible; new contradictions array names pairs where a pass is undercut by a failure 37 tests.
📝 WalkthroughWalkthroughThe production audit now supports validated repository waivers, weak-evidence classification, and contradiction detection. Markdown and JSON reports expose these results. Workflow guidance documents waiver handling and prohibits agents from creating waiver files. Tests cover the new behavior. ChangesProduction audit reporting
Estimated code review effort: 3 (Moderate) | ~20 minutes Merge Risk: 🟡 Moderate · up to The PR improves waiver and contradiction handling, but unresolved waiver bugs can falsely show checks as accepted or allow future-dated approvals to suppress failures, while unescaped waiver text can distort the audit record. These bounded correctness and audit-integrity risks should be fixed or explicitly accepted before merging. Sequence Diagram(s)sequenceDiagram

Reject future-dated waivers.
A waiver dated one day after the current date has age == -1, passes the expiry check, and changes a failing check to waived. Reject dates after the audit date and add a regression test.

Only report waivers after they waive a failing check.
Line 1442 copies every valid entry into waivers_applied before the audit evaluates checks. A valid waiver for an unknown ID, a passing check, or a profile-skipped check appears in JSON and Markdown as applied, although no check has status: "waived".
Initialize this list empty. Append the sanitized waiver only inside the w and c.status == "fail" branch. Report unmatched entries as diagnostics. Add coverage for an unknown waiver ID.

Escape waiver values before rendering Markdown tables.
Line 1608 inserts reason, evidence, and approved_by directly into table cells. A valid value containing | or a newline creates extra columns or rows. This can alter the audit record that reviewers use for waiver approval.
Normalize line breaks and escape Markdown table delimiters before rendering waiver fields. Apply the same normalization to the waiver text included in each check detail.

Acts on feedback that weak text matches versus verified evidence is where audit tools fall apart, and that the phase-gated fix brief's handling of conflicting signals is the part worth pressure testing hardest. All three defects below were reproduced on fixture repos before being fixed.
1. The phase gate was a trap
A repo whose CI runs in an org-level pipeline has no
.github/workflows/.ci-1andci-2fail critical,--fail-on criticalexits 1, and the Phase 1 gate demands it exit 0. There was no waiver mechanism of any kind (grep -c waivreturned 0). The gate could never pass, so the available moves were: add a duplicate pipeline (the brief itself warns this causes double deploys), fake a workflow file to satisfy the scan, or loop..prod-audit-waivers.jsonrecords a human's dated, evidenced acceptance. Every field required; rejected entries printed; expires after 180 days and the finding returns; listed in every report with the approver's name.SKILL.mdnow forbids Claude from writing this file — an agent that waives its own blockers has learned to game the scan.2. A grep hit could be celebrated as a clean win
Reproduced: a repo whose only rate-limiting evidence is
const limiter = { rate_limit: 100 }scored Resilience & Failover 100/100 with zero fails, which the report template writes up under "What's already solid." Categories now exposehas_weak_evidence; the table marks them "(text match only)"; the template routes them to a separate "Looks fine, but only from a text match" section.3. Conflicting signals were invisible
sec-4weak-passing ("no secrets found") whilesec-2fails critical (".gitignore does not exclude env files") means the clean scan is unproven — a real.envcould be committed and never match a pattern. Nothing said so. Newcontradictionsarray covers four pairs: sec-4/sec-2, log-4/log-1, test-1/ci-2, res-2/ms-1. The brief must resolve them before its phases.Verified end to end
Trap fixture, three waivers, one deliberately dated 2024: valid pair applied and unblocked, expired one rejected with "The finding is back",
sec-2still critical (a real in-repo fix), contradictionsec-2 + sec-4reported, all three new report sections rendered.Summary by CodeRabbit
