docs: record the property-invariant wave in the audit delivery log

[ndycode]

Summary

• Doc-only. Appends §5.3 to docs/audits/AUDIT_2026-06-10.md, recording the property-invariant wave the same way §5.2 recorded the direct-coverage wave — keeping the audit's delivery log the single record of what each wave produced.

What Changed

• New §5.3 narrative + ten-row table covering the fast-check suites test: property-check the circuit breaker's availability contract #592–test: property-check env boolean parsing and policy key/tag contracts #601 (circuit breaker, auth rate limiter, session affinity, table formatter, health classification, model resolution, display-width/keys, forecast decisions, context-overflow recovery, env/policy parsing).
• The narrative records the wave's honest outcome: across ~fifty properties, no production bug was found — the implementations held — while the review cycle caught three latent defects in the test harnesses themselves (test: property-check table formatter alignment under unicode content #595's padding/content conflation, test: property-check SessionAffinityStore TTL, eviction, and reindex contracts #594's expiry-inheritance model divergence, test: property-check context-overflow classification and synthetic SSE #600's dropped async-property promise) and fast-check caught two more modeling gaps pre-push. The wave hardened the tests as much as it verified the code, which is worth preserving for future testing decisions.
• Section inserted between the existing §5.2 and §6; no captured findings or evidence are modified (additive snapshot note per the docs/audits/ preservation policy).

Validation

• npm run typecheck (pre-commit hook)
• Markdown only; no code paths touched
• All ten PR links and suite filenames checked against the open PRs

Docs and Governance Checklist

• Audit-history doc only; additive; preserves all existing content verbatim

Risk and Rollback

• Risk level: minimal — additive markdown in an audit history file. Worst case is an adjacent-line conflict if §5.2's tail or §6's header moves on another branch (none currently touches them).
• Rollback plan: revert the commit; nothing depends on the section.

Greptile Summary

additive doc-only change: appends §5.3 to the audit delivery log, recording the property-invariant fast-check wave the same way §5.2 recorded the direct-coverage wave.

• adds a narrative paragraph and ten-row table covering prs test: property-check the circuit breaker's availability contract #592–test: property-check env boolean parsing and policy key/tag contracts #601 (circuit breaker through env/policy parsing), including honest outcome notes on the three test-harness defects the review cycle caught and the two modeling gaps fast-check caught pre-push.
• insertion is between the existing §5.2 tail and §6 header; no captured findings or evidence are modified; separator formatting matches the document's existing pattern.

Confidence Score: 5/5

purely additive markdown; no code, no dependencies, no risk to the running application.

the change appends one new section to an audit history doc, preserving all existing content verbatim. insertion point is correct (between §5.2 and §6), separator formatting matches the document's pattern, all ten pr links are present and internally consistent with the narrative, and no executable paths are touched.

no files require special attention.

Integration evidence for the wave this PR records: a local octopus merge of all ten property branches (#592–#601) onto current main completed with zero conflicts, and npx vitest run test/property/ on that integration tree passed 18 files / 112 tests — the ten new suites plus the eight pre-existing property files together in one run. No cross-suite module-state or fake-timer interference, so the ten PRs are co-mergeable in any order.

Full-suite integration evidence (supersedes the directory-scoped run above): on the ten-branch octopus merge in an isolated worktree, npx vitest run --maxWorkers=1 across all 327 files came back at 54 failing test names — every one inside the 58-name §7 environment baseline, zero new names (the four absent baseline names are the known intermittent storage cascade victims that #590 fixes for good). Totals: 4899 passed / 54 failed / 9 skipped of 4962.

So the wave is proven at both granularities: the property suites pass together (18 files / 112 tests in test/property/), and the combined tree leaves the other ~310 files at exact baseline parity. The ten PRs are co-mergeable in any order with no interaction effects.

One process note for the record: a first full-run attempt produced bogus Cannot find module load failures because it shared the working tree with concurrent review-fix branch switches; the isolated-worktree re-run above is the valid artifact.
