The source evidence remains the only raw sensor master. A LAB replay cache and
unchanged camera inputs use hard links on the same filesystem; no second copy of
the source RRD, video or native K1 capture is created. Derived arrays are stored
only when the run did not already persist a viewer-ready form. Deleting a LAB

The source evidence remains the only raw sensor master. Full-session LAB replay
caches and unchanged camera inputs use hard links on the same filesystem; no
second copy of the source RRD, video or native K1 capture is created. A bounded
experiment instead stores a small derived RRD slice with exact start/end markers
and omits the source's unbounded recorded-video descriptor. Its integrated
perception overlay owns the matching bounded camera. This prevents Rerun from
holding the final AI frame while a longer source cloud continues to play.

duration and base RRD range must equal the E21 visual result range; attaching
the 60-second result to the complete 8:55 source replay is an invalid
presentation because latest-at image data would appear static after the E21
window ends.
The first preparation of a long capture can take time because every decodable
point/pose message and every valid K1 `ModelingReport` is projected into RRD.
