The eleven `.js` files under `src/components/ai-assistant/`: the blocks
format, contexts, routing, history, placement, viewport, the greeting
and prompt tables in `dynamic`, the derivations in `insights`, and
`uiEdit`, whose boundary batch 1 already typed.
79 errors, and two optional markers cleared 63 of them.
`plural(n, word, irregular)` is called with two arguments sixty times in
`dynamic.ts` and its own body reads `irregular || \`${word}s\``, so the
third parameter has always been optional in everything but the
signature. `heading(value, sub)` is the same: `sub` is spread into the
block and `undefined` is what most callers mean. Marking both optional
is a statement about the existing contract, and the markers erase — the
emitted signatures still read `plural=(n,word,irregular)` and
`heading=(value,sub)`, checked in the output rather than assumed.
Those three `heading` errors landed in `lib/skills/workforceFlow.ts`,
already migrated and untouched here. Worth noting how that works: a
function's arity only starts being enforced on its callers once the file
defining it is TypeScript. Migrating a leaf makes claims about every
file that imports it, which is why this phase moves bottom-up.
The remaining nine were two `reduce` accumulators inferring `{}`, so
`Object.values` over them produced `unknown`. Both are now stated —
`{ label, count }` for the score bands, and the five-field hire grouping
— which is more useful than `any` and exactly what the lines below them
build.
Measured against `dde4ba6`:
typecheck 6 errors, unchanged; no new error anywhere
lint exit 0, 0 errors, 289 warnings
npm test 1684/1691, the same 7 failures verbatim
build exit 0, identical bundle hash 74d17e2d…
type erasure 83/83 byte-identical across Phase 11 so far
No baseline artifact touched.
