Catches up the story's checkbox + frontmatter status to reflect that
the slice shipped in commit 1bbe866. The V1 orchestrator landed the
implementer's slice commit on main but had no state-mutation step,
so the bullet stayed unticked and `pnpm work next` would have
redundantly re-dispatched the implementer for a no-op slice.
Bookkeeping-only — no code changes.
Re-decomposes the approved binder-wrap-helper PRD after the previous
8-story attempt (dropped in 71c04f5) sliced horizontally — its
"write test" / "write impl" splits would have left intermediate
commits red. The new shape obeys slice = task = PR = commit:
- 01-wire-use-case-helper — 1 task: ship the wireUseCase helper
(factory composition + container bind + brand stack) with its
unit tests and barrel export in one green commit. Blocks 02 + 03.
- 02-migrate-feature-binders — 5 tasks, one per feature
(auth, blog, media, marketing-pages, navigation). Each task
migrates that feature's bind-production.ts + bind-dev-seed.ts
together and keeps all gates green.
- 03-update-generator-templates — 1 task: update the feature
generator's bind-*.hbs so future scaffolds emit wireUseCase
directly instead of inline withSpan + withCapture.
Output of the now-fixed sandcastle decompose dispatch — depends on
the completionSignal + maxIterations wiring (eadbb7e, 26aa97f).
