Marc-André Bombeck 2d03eba587 fix(google-health): resume a backfill inside a collection and run it in short slices
A backfill noted progress only once a whole collection was read to the end.
A heart-rate history of years that one attempt could not finish (its budget,
a rate limit it could not wait out, a single failed request among thousands
of pages) started the next attempt from the newest page again, finished
nothing, and failed with "marker not stamped" on every attempt.

- Every spot-reading collection read page by page now records, after each
  page it writes, the oldest sample it has written (backfillProgress.cursors).
  The next attempt asks Google only for samples at or beyond that edge. The
  edge is held back once a page's write fails, so no rows are skipped.
- The backfill runs in slices of five minutes or 500 pages. A slice that
  finished a collection or moved an edge continues with the next one; only a
  slice that moved nothing fails, and its error names each unfinished
  collection and why the slice stopped. The slice ceiling is derived from the
  collections and the page ceilings of the resumable ones.
- A rate limit Google will not lift within a minute ends the slice instead of
  failing the walk, and the next slice starts five minutes later. Server
  errors, timeouts and dropped connections are retried three times.
- The heart-rate stream is read last, so the light collections finish in the
  first slice.
- The hourly sync waits up to eight minutes for a running slice instead of
  skipping the account for as long as the import runs.
- Each slice annotates googleHealth.backfill.slice with pages, elapsed time,
  stop reason, per-collection status and edges, and reports progress on the
  job.progress line.

docs/ — internal reference + operator playbooks

The user-facing documentation lives at https://docs.healthlog.dev — that's the canonical surface for self-hosting guides, integration walkthroughs, AI-provider setup, and the doctor-report workflow.

The files in this directory are the internal operator playbooks, audit notes, and machine-readable specs that ship alongside the source:

  • api/ — the OpenAPI 3.1 spec for the native-client subset (iOS DTO codegen target). See api/README.md for the preview commands. Also home to the MCP-server contract: api/mcp-capabilities.md (tools, resources, prompts, write model) and api/mcp-skills.md (building a connector / skill).
  • ops/ — operator runbooks: deploy, backup / restore, encryption-key rotation, password reset and account recovery, env checks, TLS pinning, data repair. These are what an operator reaches for during an incident.
  • self-hosting/ — horizontal-scaling notes (HEALTHLOG_PROCESS_TYPE=web|worker|all) and the deploy-pipeline recipe. Routine install steps stay on docs.healthlog.dev. Includes self-hosting/mcp.md — enabling the off-by-default MCP connector and pointing Claude.ai / ChatGPT / Claude Desktop at it, and self-hosting/sso.md — OIDC SSO login: IdP setup, the identity-pinning security model, OIDC_ONLY consequences, and the break-glass runbook. Also self-hosting/geolite2.md — bringing your own offline GeoLite2 databases via GEOLITE2_DIR instead of sending login IPs to a third-party lookup. And self-hosting/account-sharing.md — letting one account on the instance open another's health record: the three access levels, the eight sections a grant can be narrowed to, managed profiles for somebody with no login and the guardians who look after them, what revocation does and does not undo, and which trust properties of the instance are unchanged by any of it.
  • using/ — notes on using the app that sit close to the code. using/search.md covers the command palette's record search: opening it, what it finds, how matching works, and its limits on very large and shared records.
  • migration/ — migration notes. Currently only v1.3 to v1.4; later releases are covered by CHANGELOG.md and https://docs.healthlog.dev.
  • integrations/ — per-integration reference (Withings, Fitbit, Google Health, WHOOP, Apple Health, AI providers, data import).
  • adr/ — architecture decision records.
  • security/ — threat-model notes.
  • diagrams/ — architecture diagrams rendered through docs.healthlog.dev.
  • releases/ — release imagery.
  • apple-store-connect-checklist.md — the iOS submission gate.
  • codex-protocol-spec.md — Codex / ChatGPT OAuth protocol reverse-engineering notes.
  • ui-guidelines.md — UI / a11y house style.
