BBergleandClaude Sonnet 5 244fe525dd docs: mark Phase 0 done, record D19 (auto-update, deferred)
CI / Repo hygiene (pull_request) Successful in 2s

docs/PLAN.md's Phase 0 section and its "Done when"/Verification entries
still described the original Postgres+RLS, docker-compose, auto-redeploying
design — none of which is what actually got built and deployed. Marks it
done, states the two deliberate deviations plainly (SQLite not Postgres+RLS,
manual redeploy not automatic), and separates what's actually verified
(login persists a session, checked by scripts/smoke-test.sh after a real bug)
from what nobody has tried yet (PWA home-screen install).

docs/DECISIONS.md D19 records the auto-update investigation: the real fix
for Unraid's own "not available" update-check badge (a third, independent
place the D17 self-signed cert needed trusting — Unraid's PHP update
checker doesn't share Docker's own certs.d), the structural reason "up to
date" can't be fully trusted on this host even after that fix (CI builds on
the same dockerd the app runs on, so the local :latest tag is always fresh
regardless of whether the container was recreated from it), the failed
first Watchtower attempt (stale image, wrong Docker API version) and why
CI-triggers-a-redeploy was rejected again rather than reconsidered.
"Deliberately deferred" gets three new entries: finishing Watchtower,
migrating Gitea/CI to a dedicated VM (raised as the real fix for the
root cause D19 kept running into), and persisting the accumulated
host-local trust files across a reboot.

BBergleandClaude Opus 5 e7392a5723 refactor(api): move from Postgres+RLS to single-engine SQLite

Reverses a shipped, tested, merged decision (D4/PR #2) rather than building
on it — see docs/DECISIONS.md D15 for the full record: what was rejected
(Postgres as a second container; Postgres+PostGIS bundled inside the single
container via a supervisor), what this costs (no database-level RLS, no
PostGIS, procrastinate needs replacing — all stated as a concern before this
was decided, and reaffirmed anyway, which is the user's call to make about
their own instance).

The one invariant-critical consequence: isolation between users now rests
entirely on the repository-layer scope (db.py's `Scope.select()`), not two
layers. CLAUDE.md's invariant #4 is revised accordingly. This is not a
downgrade-and-hope — `Scope` is built so an unfiltered query against a
user-owned table is structurally harder to write than a scoped one (there is
no method on `Scope` that returns one), and
tests/test_auth.py::test_scoped_session_blocks_cross_user_reads replaces the
old RLS proof with the same empirical standard: it doesn't trust the query
builder filters correctly because the code reads correctly, it registers two
real users and checks.
test_unscoped_session_can_see_every_user_when_misused is the deliberately
alarming companion — it demonstrates exactly what a reviewer must now catch,
since nothing else will.

Six real, non-obvious SQLite behaviours found and fixed by actually running
this against a real file, not assumed from docs:

- Foreign keys, ON DELETE CASCADE included, are OFF by default per
  connection — deleting a user silently left orphaned sessions/api_tokens,
  no error either way. Fixed with PRAGMA foreign_keys=ON on every connect.
- Transactions default to DEFERRED, which only takes a write lock on the
  first actual write — a real check-then-act race for invite redemption
  (two concurrent redemptions could both read used_count < max_uses as true
  before either commits). Fixed by disabling the driver's implicit BEGIN and
  issuing BEGIN IMMEDIATE ourselves — SQLAlchemy's own documented recipe for
  this, not improvised.
- DateTime(timezone=True) does NOT round-trip tzinfo on SQLite — a tz-aware
  datetime goes in, a naive one comes back out, and every
  `expires_at < datetime.now(UTC)` comparison in auth/service.py then raises
  TypeError. Fixed once at the Base level with a UTCDateTime TypeDecorator
  rather than per-column.
- Uuid(as_uuid=True) stores as 32-char hex with NO hyphens on SQLite, not
  str(uuid)'s hyphenated form. A test fixture that raw-inserted the
  hyphenated form left rows the ORM's own later UPDATE (via
  invite.used_count += 1's autoflush) could never match by primary key,
  updating zero rows and raising StaleDataError. Fixed by using .hex to
  match exactly what the ORM itself writes.
- BEGIN IMMEDIATE applies to every transaction, reads included — a
  long-lived test fixture that autobegins a transaction via a bare read and
  never explicitly closes it holds SQLite's exclusive write lock for the
  rest of the test, and a later scoped_session() call fails with "database
  is locked". Not an app-code bug (every real session block closes cleanly
  on exit), but real enough to document since the next person writing a
  test against the db_auth fixture will hit it too.
- Python's sqlite3 module deprecates its own implicit datetime adapter as of
  3.12 — silent today, warns on every raw-SQL datetime bind. Only ever hit
  test fixture code (the ORM path never uses it, confirmed by running the
  ORM-only health test with warnings promoted to errors and it stayed
  clean); fixed there with an explicit .isoformat() rather than left for a
  future Python version to turn into a real failure.

Also, since with_for_update() silently no-ops on SQLite (confirmed —
SQLAlchemy emits no SQL for it, no error either) rather than actually
locking anything: removed it from register()'s invite-redemption query and
corrected the comment to attribute the concurrency guarantee to BEGIN
IMMEDIATE, where it now actually lives.

One PR, not several, for the same reason PR #2 was: the migration, the
models, db.py, and the docs recording why are five views of one decision —
splitting them wouldn't make review easier, just disconnected. 552
insertions / 548 deletions across 17 files, most of it necessarily touching
what PR #2 shipped rather than net-new code.

Deliberately deferred, not solved here: PostGIS's replacement for spatial
storage, procrastinate's replacement for background jobs, and the
EXCLUDE USING gist constraint's replacement for component_installs — none
of those tables exist yet (Phase 1-2), so none of it is broken, and
docs/DECISIONS.md D15 records exactly what each future phase needs to
decide before it can be built. .gitea/workflows/deploy pipeline (PR #4,
built for the old 3-container Postgres compose stack) was closed as
superseded rather than merged; the single-container image build is
follow-up work, not part of this change.

Verified: ruff check, ruff format --check, and mypy --strict all clean.
13/13 pytest passing against a real SQLite file, including with
DeprecationWarning promoted to an error (confirms the sqlite3 adapter
deprecation fix actually holds, not just that it's quiet by default). Full
alembic upgrade -> downgrade -1 -> upgrade cycle run clean. alembic check
clean with no include_object filter needed at all now (SQLite starts with
nothing but what our own migrations create — no PostGIS/TIGER noise to
filter out in the first place). CI's exact migration command sequence
reproduced locally end to end before touching the workflow file.

BBergleandClaude Opus 5 d3f5ed7e7b Add planning docs for self-hosted cycling app
Planning output only; no application code yet.

Key findings driving the design:

- The Bryton Rider 650 has on-device Wi-Fi (Main Menu -> Data Sync) and
  uploads to Bryton's cloud with no phone and no Bryton Active app. Paired
  with the reverse-engineered Bryton cloud API — which returns the original
  unmodified FIT bytes — this makes ride sync fully hands-off, and higher
  fidelity than the current Strava route (Strava's API cannot return the
  original file, only smoothed streams).
- Build fresh rather than forking Endurain or FitTrackee; borrow Endurain's
  gear/component structure and strava-gear's retroactive time-ranged wear
  computation.
- PWA rather than a native iOS app: iOS 16.4+ gives home-screen PWAs real
  push notifications, which was the only thing that used to force native.

Docs:
  docs/PLAN.md       stack, schema, ingestion, auth, notifications, roadmap,
                     CI/CD, risks, verification
  docs/RESEARCH.md   Bryton cloud protocol, FIT library comparison,
                     maintenance intervals, geo services, Gitea gotchas
  docs/DECISIONS.md  decisions taken, alternatives rejected, rationale
