The fifteen files under `src/components/agents/` (including `skills/`)
and `src/components/skills/`. 15/15 erase byte-identically; bundle hash
unchanged.
Renaming raised 43 errors and 29 of them came from one thing: these
files carry 24 `/** @param {any} props */` annotations, one per
component, and JSDoc stops applying at the extension boundary. Without
them TypeScript infers every destructured prop as required, so a call
site passing seven of nine props is an error — which is how a file that
declared its props `any` ended up with fourteen complaints about missing
`className`. Restoring the author's own declaration as `: any` is not
blanket typing; it is the annotation that was already there, in the only
form that still works.
`Workspace` in `AgentCanvas` was the one component in that file its
author left without the hatch. It now matches its siblings.
The rest were five separate things:
- `React.isValidElement(children)` no longer narrows enough to read
`children.props.id`: React 19 types `ReactElement`'s props as
`unknown`. `isValidElement<any>` says what the `cloneElement` call
beneath it has always assumed. The migration plan predicted this
site by name.
- `useSkillSections(page, placement)` is called with one argument by
`UiEditingProvider`, which its doc comment explicitly permits —
"called with no placement it returns every section on the page". The
parameter simply lacked its optional marker. The marker erases, so
the emitted signature is unchanged.
- `new Date(b.at) - new Date(a.at)` is valueOf coercion, which
JavaScript performs and TypeScript refuses to describe. Cast rather
than rewritten to `.getTime()`: that would change the emitted code,
and this comparison orders the list.
- `Object.values<any>` on a tally, the same inference gap as earlier
batches, which also fixed a `ReactNode` complaint downstream of it.
All fifteen are linted under their new extensions, checked by name.
Measured against `446df7b`:
typecheck 6 errors, down from 9; no new error anywhere
lint exit 0, 0 errors, 289 warnings, 15/15 linted by name
npm test 1684/1691, the same 7 failures verbatim
build exit 0, identical bundle hash 74d17e2d…
type erasure 72/72 byte-identical across Phase 11 so far
No baseline artifact touched.
