parity` prints this line on every run, so it stays current):

**By remaining effort** — rows are not equal: a shortcut and the whole Book module are one row each, and what is
left is the heavy part (AI, video, Classic output modules, undocumented raw codecs). Remaining work in **Opus agent-hours**

UI/feature work in ≈ 5 h on 2026-10-01, and four to six parallel agents built M0–M13 in ≈ 25 active hours):

uncertainty: they can finish faster if suitable permissive models / documentation turn up, or stall on licensing.

it can't decode yet.
