Documents the single-task Plan 03-04 closure end-to-end:
- A32 ships ~90 lines of best-effort RAM scaffolding per D-P3-04 +
RESEARCH Open Question 3 (host-side puppeteer.Page.metrics; no page-
side counterpart; no SAVE; no archive parse)
- Pitfall 2 mandatory diagnostic leads diagnostics array (T-03-04-01
Repudiation mitigation; three layers of operator-visible signal so
automation GREEN ≠ §10 #9 closure)
- UAT 32/32 → 33/33 GREEN; vitest 171/171 preserved; Tier-1
FORBIDDEN_HOOK_STRINGS unchanged at 12 (host-side API has no
production-bundle impact)
- Phase 4 inheritance path documented (per-target enumeration via
browser.targets() + createCDPSession + Performance.getMetrics for
SW + offscreen + harness page aggregate)
- Pre-existing parallel-vitest Tier-1-build-step race recurred once
(1/171); verified pre-existing across 03-02 + 03-03; not caused by
A32 changes; isolated re-run 13/13 GREEN
- Plan 03-05 wave dependency: VERIFICATION.md aggregator; will record
§10 #9 as `human_verification` regardless of A32 status
- Zero deviations: plan-spec verbatim implementation; the cleanest of
the four Wave-2/3/4 plans in Phase 3 by deviation count
