Yichen Jiang bf0db65bb0 fix(ui-settings-models): address review — derived key fact, required render seat, spec sync
The provider-card seat's keyConfigured now derives from the reference the
page would use — the profile's apiKeyEnv, or the page's derived
<ROUTE>_API_KEY while the profile names none — so the add-provider draft
agrees with its own editor about an existing conventional credential (the
store joins the derived describe in the same batched call, as
ProviderRow.derivedCredential). ModelsSectionProps makes the renderSlot seat
required so a direct render that forgets it fails to compile; the one such
render in provider-form.client.spec regained a real mount and the test
boilerplate collapsed to renderSlot={() => null}. The extension-slots Agent
Note now states the keyed cell's real override rule (same priority throws,
a different priority shadows), and docs/subsystems/slots.md carries the two
new seats in its hierarchy, both languages.

Subsystems

English | 中文

One page per subsystem of the DeepSeek Harness: what it is, the data structures it moves, and — where a ctx service or event scope backs it — a generated Cordis API section carrying its service and event reference. The folder complements architecture.md, which describes behavior across subsystems (the service map, the session/turn/step lifecycle, the event taxonomy); each page here is the reference for one subsystem's vocabulary and wiring.

Page Owns

Type declarations and their JSDoc on these pages are source-equivalent and drift-checked by pnpm run verify-type-equiv (see development.md). Ordinary blocks preserve complete declarations; public-api blocks preserve body-stripped public class declarations. Cordis services and events use each page's generated Cordis API section.
