Phase 1 UAT Test 3 surfaced a two-headed BLOCKER:
(a) silent empty-video archive when save crosses a port-reconnect window,
(b) 3x "Attempting to use a disconnected port object" Uncaught Errors
starting at the 290 s pre-emptive reconnect mark.
Bisect confirmed: H1 (port lifecycle race) was introduced by Plan 01-04
(b064a21); H2 (createArchive silent-skip on empty segments) is an upstream
defect (555eb05) that became fatal once CR-01 + sweep #5 guaranteed the
silent-skip branch would fire on every save during a reconnect window.
This commit lands the 3 RED tests at the unit-test level — they match the
UAT error string byte-for-byte for H1/H1.b and pin the silent-drop
contract for H2. They will flip GREEN as the Option C architectural
refactor (request-id'd port protocol + port-health probe + retry +
operator-visible error surface) lands across the next commits.
Baseline: 8 files / 43 tests (40 GREEN, 3 RED). tsc --noEmit exit 0.
