The client bundle carries only the active locale — resolved on the
server and handed to the provider with no hydration flash, halving the
dashboard route to under a megabyte parsed (288 KiB gzip). The auth
shell renders the app chrome immediately instead of a spinner while the
session resolves in parallel, the widgets request folds into the
snapshot it duplicated, and insight pills prefetch their sub-pages —
a first visit to a sub-page lands in about ninety milliseconds instead
of nearly a second.
Categories endpoint + conflict-resolution lock. A two-item follow-up to v1.4.30: the categorisation overlay shipped yesterday as a TypeScript map; the new `GET /api/measurement-categories` endpoint projects it over HTTP so the iOS-side picker can fetch the canonical shape rather than carry a hard-coded mirror — the unblocker the iOS team flagged as the one missing piece. In parallel the SyncMode conflict-resolution policy that the v0.6.0 standalone-first track depends on lands as §13 of `08-locked-contracts.md`.
