API review and wiring-support work

Observed work

An API assessment examined costs in authentication, queries, writes and pagination. Three high-priority fixes were started with a requirement to retain response and permission compatibility. Reproduction used an in-memory database and mocked dependencies; completion and representative-load retesting were not observed, so production performance cannot be inferred.

Screen timestamp and numeric-format handling were reviewed. Earlier local fixes and passing tests were reported, but deployment, device readback and a final numeric-display rule were not established.

Product wiring information supported a technical-support investigation and a requested manual-diagram update. The diagnosis and delivery of the updated manual remain unconfirmed.
