The recurring no-briefing day had a chain of causes, closed end to end:
Every failure path in the nightly pregenerate + the comprehensive generator
now annotates a queryable cause (several classes — features-error,
payload-too-large, aborted, generator-failed — previously bumped a counter
with zero trace). A failed nightly warm enqueues one bounded retry ~45
minutes later (singleton per user, existing budgets apply), so a transient
provider hiccup heals before morning. A cached payload that carries NO
briefing no longer satisfies the 24h POST short-circuit nor the
unchanged-content hash gate — a once-stripped briefing could previously
block its own regeneration indefinitely. The card surfaces the omission
reason persistently (grounding strip, generation failure, not attempted)
with a forcing retry.
Documentation corrected against code truth: Withings credentials are
per-user (the documented env path never existed; the dead example entries
and manifest rows are gone, and WITHINGS_WEBHOOK_SECRET is now actually
whitelisted in compose — stock deploys could never deliver it); the classic
Fitbit portal no longer accepts new registrations; the backup-restore
example no longer mints a fresh encryption key and uses pnpm dlx tsx; the
TLS guide describes the real client model (two CA-level SPKI pins,
any-match, leaf renewals need no build); scaling/admin references fixed;
the operator-shared subscription provider is documented.
The Fitbit integration connects through the classic Fitbit Web API, so a
self-hoster registers a Fitbit developer app at dev.fitbit.com — but the
setup guide walked users through creating a Google Cloud OAuth client,
whose client id the Fitbit sign-in rejects (unauthorized_client). Rewrite
the guide for the dev.fitbit.com flow (app type, HTTPS callback, scopes,
PKCE), leave the old page as a pointer, and add a test that keeps the
documented scopes and endpoints in sync with the client so the guide
cannot drift from the code again. Flags the September 2026 sunset of the
classic Fitbit Web API.
