PD-284-CONFRONTATION-STEP5-V2



build · gpt-5.3-codex  E-01 — RESOLVED — The CE-SSE-01 escape clause removes the contradiction by permitting a native SSE library only behind a wrapper when fetch streaming is unavailable.
E-02 — RESOLVED — The explicit 7-state to 5-visual-step mapping table is now present and closes the prior ambiguity.
E-03 — RESOLVED — failure_reason is now typed (FailureReason) and explicitly surfaced in both the progress card and expert panel.
E-04 — RESOLVED — purgeStaleSealArtifacts() is now defined in secure storage and invoked before the POST, addressing stale artifact cleanup.
E-05 — RESOLVED — The implementation plan now includes concrete technical constraints (PD-80 stub/mocks, Jest+RNTL, Metro/Hermes).
E-06 — RESOLVED — A CI-suitable proxy performance test is now defined via re-render count (<= 2) per SSE event using jest.fn().
E-07 — RESOLVED — The fail-open risk is now formalized as HT-09 (PD-80 idempotent) with a mandatory integration test, which closes the gap.

E-14 — CONFIRMED — Severity: Minor — Having two §12 sections is a documentation numbering defect and should be renumbered for clarity.
E-15 — CONFIRMED — Severity: Minor — proof_package_url is missing from SEALED expert-panel field mapping, so the mapping is incomplete.
E-16 — CONFIRMED — Severity: Minor — tsa_timestamp is typed but not displayed in any component, creating a spec/implementation visibility mismatch.
E-17 — CONFIRMED — Severity: Minor — There is no test that actually hits the 30s cumulative backoff ceiling, since defaults only total 7s.
E-18 — CONFIRMED — Severity: Minor — The boundary between strict Zod event validation and store handling of unknowns is underspecified and overlapping.

Recommendation: GO
