Two doc updates closing the debug session per the resolved pattern this
phase has established (cf. resolved/d12-blob-port-transfer-fails.md and
resolved/webm-playback-freeze.md):
1. **Move debug session to resolved/** with the Resolution section
filled in (root_cause, fix, verification, files_changed). Status
flipped tdd_red_confirmed -> resolved. Original investigation
notes + bisect results + Option C strategy spec all preserved
in-place — the file is the full provenance trail.
2. **Amend 01-CONTEXT.md D-17** with the new port lifecycle commitments.
Append-only (D-17 itself untouched) per the doc cascade rule
established earlier this phase ("amendments append, do not replace,
to preserve SPEC provenance"). The amendment narrates:
- What was Claude's-discretion at Phase 1 plan time has been
specified by Option C.
- The 290 s pre-emptive setTimeout reconnect (Pitfall 4) is RETIRED.
- The architectural commitments added: PING/PONG health probe,
request-id'd REQUEST_BUFFER/BUFFER, SW retry on port replacement,
outer 10 s hard-timeout, operator-visible EmptyVideoBufferError
surface.
- The 4 pinning contracts added (port-health-probe,
request-id-protocol, port-lifecycle-continuous, plus the
refactored port-reconnect-race).
Suite remains 11 files / 53 tests, all GREEN. Quality gates intact.
