# 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.

## Commits

- dea6cb6: docs(260607-u8o): mark Phase 1 UAT item 4 (SSE smoke) PASS
- 26655cf: docs(260607-u8o): mark Gate 2 Part C SSE row + summary PASS

## Self-Check: PASSED
