F-139 — Implementer evidence

What

F-139 build evidence: fixed SSE streaming bug. tsc 0, verify.sh verde.

Files

  • apps/admin/src/app/api/[...path]/route.ts — proxy adds X-Accel-Buffering: no, uses Headers API, removes Connection: keep-alive.
  • apps/admin/src/components/ServerLogViewer.tsx — added exponential backoff reconnection loop (1s → 2s → 4s … max 30s); calls reader.cancel() on abort; resets backoff on success.

Verification

  • npm run build → 0 TypeScript errors.
  • check-module-boundaries.mjs src → 0 NEW violations.
  • ./scripts/verify.sh → green (F-139 in_progress, runtime-consistent).

Root causes fixed

Cause Fix
Proxy missing X-Accel-Buffering: no Added header to proxy SSE response
Client never reconnects Exponential backoff retry loop in connect()
Dead LogBroadcaster.stream() No-op — never used by SSE endpoint
