`[2026-07-01]` **heid-code-review (`v0.19.3`, `75dec01`) — panel caught 2 real client-side SSE-lifecycle bugs TDD missed.** Contract-anchored (authored the web contract to enable it — no contract → no drift axis). Gróa/Hulda/Regin (artifact-only, Gróa under Landlock jail): ZERO functional server-side drift + INV-004 clean; 2 genuine drifts on the un-unit-tested SPA — (1) turn `es.onerror` didn't `hideThinkingNote()` (reasoning line + setInterval leak on a raw drop), (2) `openAdminEvents` never closed the EventSource on error → native auto-reconnect RETRY LOOP (fixed: close on `stream_error` + permanent `onerror`/CLOSED; transient CONNECTING still reconnects). + 2 test-gaps fixed (route-registration + admin stream_error). 1 precision → contract-clarified (tools-inventory names-only by design). **Re-confirms: the JS render/lifecycle paths are the review's highest-value target — unit tests don't reach them (same lesson as #18 D2).**
