Quick Task 260607-u8o: Record SSE-over-Pangolin Smoke Test PASS Summary
Recorded the live SSE-over-Pangolin smoke test PASS (Phase 4 entry gate, D-14 / issue #1034) in the two gate-tracking docs, clearing the gate for Phase 4 planning.
What Was Done
Documentation-only record-keeping. The SSE smoke test was executed live and PASSED; this task transcribes that result into the gate docs with verbatim evidence.
Task 1 — 01-HUMAN-UAT.md: item 4 (SSE-over-Pangolin smoke) changed from result: [pending] to a PASS (2026-06-08) note with full evidence; Summary updated passed: 0 → 1, pending: 4 → 3. Items 1–3 (AUTH-01/02/03) untouched.
Task 2 — 03-GATE2-RESULTS.md: Part C row C1 changed from [ ] PENDING — operator to ✅ PASS (2026-06-08) with evidence in the Notes cell; Summary Part-C row changed from ⏳ DEFERRED to ✅ PASS (2026-06-08). No other rows or the outcome paragraph touched.
Evidence Recorded (verbatim)
Endpoint: GET /api/sse/heartbeat over familysync-dev.bergerhouse.net (Pangolin → Newt → api) with a valid authenticated session cookie.
Duration: stream held open ~6 min (01:37:53Z → 01:43:54Z) before manual termination — past the 5-min bar.
Heartbeats: 35 heartbeat events, id 0 → 34, ~10s cadence.
Delivery: response bytes grew 71 → 2535 incrementally → Pangolin response buffering OFF (not a buffered end-of-stream dump).
Result: no early proxy cut. PASS. Phase 4 entry gate (D-14 / issue #1034) CLEARED.
Caveat (recorded, not overstated): proves no idle-timeout cutoff and no buffering over ~6 min; does NOT prove the absence of a max total connection-duration cap. That residual risk is covered by the already-decided Phase 4 design (D-10/D-11/D-12 in 04-CONTEXT.md).
Deviations from Plan
None - plan executed exactly as written.
Verification
passed: 1 present in 01-HUMAN-UAT.md; no passed: 0 remains.
No PENDING — operator or ⏳ DEFERRED markers remain in 03-GATE2-RESULTS.md.
Only the two intended files were modified (git diff --name-only); no source, no 04-CONTEXT.md, no ROADMAP.md.
