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.
The simplified request path no longer anchors an unchanged request/header on
resume (agent.ts logs a header only when it differs from the folded baseline),
so resume-turn logs drop that event and later seqs shift down. Refresh the
keyless session-log fixtures to match; no model scripts changed.
