Library expansion pilot: 20 recordings with notes and original art
First batch of the expansion toward full-channel coverage: the 20
newest missing recordings (12 videos, 8 streams, including the
same-day Boot Camp upload and the late-2020 political-era streams,
documented plainly and neutrally). Each gains a source note, a library
record, and an original artwork in the established atlas system
(expansion v2 batch-a: prompts, index, 1536x1024 masters via butler
imagen with one full-bleed regeneration, four responsive encodings
each via the new scripts/encode_library_art.sh). All 20 renders were
individually reviewed against the series' rejection criteria.
Library grows 108 -> 128; coverage now 2020-08-26 through 2026-08-17;
validators, fixtures, pagination, and the art gate updated accordingly.
Full test suite and tests/verify_library_art.sh pass.
