The update poller and the chunk-error reload guard key on the target
version instead of disarming for the whole session, so a second deploy
re-arms the self-heal and a stale shell can no longer strand with
404ing chunks. Lazy chart imports retry once and mount inside a
per-card error boundary with a reload affordance — a failed chunk
degrades to one card instead of replacing the page. The JSON API
client attaches a fifteen-second timeout unless the caller brings its
own signal (the raw streaming path is exempt), chart queries surface
errors with a retry instead of rendering as an empty period, per-type
fetch failures reject instead of caching an empty series as fresh, and
the session and snapshot queries retry once on transient network or
server errors.
The self-context adopt runs read-modify-write inside one transaction,
the admin shell renders nothing until the role is confirmed, and the
json-body helper merges Headers instances correctly. The compose image
reference accepts a pinned digest through an env var, and a promote
script resolves the published digest, verifies its signature and hands
the operator the exact pinning call — the documented path away from a
moving latest tag.
A typed apiFetch wrapper owns the envelope unwrap, the ok-check and the
error read for every client call — two hundred call sites across the
app migrate onto it and a lint rule keeps raw api fetches out for good.
The legacy timezone helpers fold into the tz module and test fixtures
drop personal names.
