Media trim rebases timestamps · case 05
Trimmed media retains source timestamps instead of beginning at the trim-relative timeline.
Case contract
Select frames whose presentation starts lie in half-open trim interval and rebase their timestamps by subtracting trim start.
Why this case matters
A deterministic local media controller stage; metadata and downloaded data are supplied explicitly. No external player, service or codec is required.
One recorded failure
