Adjudicate Codex's review correction: concede three overstatements in
the original review (M3 loop not actually complete - InstallService has
no production assembly and T-401 launch is unbuilt; scope 'no security
defect' to T-302/T-303; O2 mischaracterized - ENOSPC during io.Copy is
misclassified as zip_corrupt with a broken error chain, escalate to P1;
O1 fix was flawed - recheck IsRunning explicitly instead of inferring
app_running from rename failure). Add finding: disk-full surfaces at
write/sync/close with three different codes, so the O2 fix must span the
whole write->sync->close sequence.

Code-level audit of the verified install chain: hash-before-parse and
single-file-handle TOCTOU defenses in verified_package.go, strict
app.json parse cross-checked against the signed Catalog, untrusted
download verified against Catalog Size/SHA256, mandatory non-bypassable
pre-extract disk/running checks, and a complete stable failure-code
enum. No security defect found; records five minor optimizations, the
top being the IsRunning TOCTOU (recheck before the current->backup
rename).

Verify at code level that the Phase 1/2 review findings were actually
closed (not just self-reported): icon cache concurrency + LRU + bounded
fetch (T-606), UI-thread icon delivery (T-607), install durability with
Windows FlushFileBuffers / POSIX dir sync (T-613), ZIP central-directory
preflight (T-612), and catalog signature cross-impl vectors (T-614).
All confirmed real. Records three residuals (R1 real power-loss
validation, R2 per-file fsync cost, R3 singleflight ctx caveat).
Also gitignore *.code-workspace (per review recommendation).

Record the full-stack review of the Phase 0 skeleton (T-001~T-004),
Codex's second-pass rebuttal, and the cross-checked final ruling:
confirmed facts (with evidence), accept/correct notes, and a
finalized action order. P1 (root go.work Win7 version bleed) is the
only structural fix flagged for near-term handling.
