The native adapter's route was named deepseek, colliding with pi-ai's
catalog provider of the same name, so the two DeepSeek paths could never
be mounted side by side. The web settings page needs both configurable at
once. Compositions, fixtures, goldens, scaffolding defaults, and docs all
move together (pre-release, no shim); TUI/session-query-spill/
missing-credential goldens re-recorded through their keyless refresh
modes because provider-name length shifts box padding and spill
truncation points.
An overlay pair switches the acp demo's packChunks on; the authored fixture
(text-turn's recording refreshed through that overlay) commits a session.jsonl
whose reasoning run persists as one packed reasoning-chunks row while the
short text run stays verbatim. Keyless replay proves the packed fixture
derives the same model script (fixture reading is layout-blind) and the
re-persisted log packs identically — the transcript surface of the packChunks
switch is now pinned without touching any existing golden.
