#+title: phone capture tasks
#+startup: overview
#+todo: TODO(t!) NEXT(n!) HOLD(h@!) | DONE(d!) CANX(c@!)

* goal
build a tiny android-to-org capture system.

the app must be instant-feeling, capture-only, and boring. the phone stores notes locally, then posts them to a lan-only server. the server appends validated entries to a central org file.

* decisions
- android-only native app.
- kotlin + jetpack compose.
- room sqlite for local queue/history.
- okhttp or retrofit for http.
- workmanager for opportunistic sync.
- python fastapi listener in docker.
- server owns all writes to the canonical org file.
- phone never edits org files directly.
- server dedupes by capture id.
- no nextcloud/file-sync dependency.
- no org parser on phone.
- no public exposure.

* acceptance criteria
- opening the app focuses the text field automatically.
- saving a note works offline and returns the user to an empty entry state.
- captures include local created timestamp with timezone.
- user can mark capture as todo.
- user can add optional tags.
- manual sync posts all pending captures when server is reachable.
- server appends valid captures to `phone.org`.
- duplicate posts do not create duplicate org entries.
- failed sync attempts remain visible and retryable.
- app shows at least pending/synced/failed history.
- service can run in docker on jeeves/unraid.
- service has a `/health` endpoint.
- service rejects missing/invalid auth token.
- service rejects empty capture body.
- service has tests for org formatting and duplicate handling.

* milestone 0: repo setup
** TODO create monorepo skeleton
*** acceptance
- `android/`, `server/`, and `docs/` directories exist.
- root `README.md`, `tasks.org`, `.env.example`, and `docker-compose.example.yml` exist.
** TODO add root gitignore
*** acceptance
- ignores android build outputs.
- ignores python virtualenv/cache.
- ignores sqlite db files.
- ignores local env files.
- does not ignore docs or source files.
** TODO document v1 scope in README
*** acceptance
- states capture-only scope.
- states non-goals.
- states architecture and build order.

* milestone 1: server mvp
** TODO create fastapi app
*** acceptance
- `GET /health` returns 200 with simple json.
- `POST /capture` accepts a valid capture payload.
- auth token is required for `POST /capture`.
** TODO define pydantic capture model
*** acceptance
- requires id, created_at, kind, body, tags, and device.
- kind is constrained to note/todo.
- body is trimmed and must not be empty.
- tags are normalized before formatting.
** TODO implement org formatter
*** acceptance
- todo captures produce `* TODO ...`.
- note captures produce `* note ...`.
- org property drawer includes created, source, and id.
- tags are emitted as org heading tags.
- multiline note body is preserved.
- tests cover todo, note, tags, empty tags, and multiline body.
** TODO implement sqlite idempotency store
*** acceptance
- accepted capture ids are stored.
- repeated id returns accepted/already-seen without appending.
- db path is configurable.
** TODO implement append writer
*** acceptance
- appends to configured org path.
- creates file if missing.
- writes utf-8.
- appends exactly one entry per new capture.
- uses file lock or equivalent simple concurrency guard.
** TODO add server tests
*** acceptance
- health endpoint test.
- valid capture append test.
- duplicate capture test.
- invalid token test.
- empty body rejection test.
** TODO containerize server
*** acceptance
- dockerfile builds server image.
- compose example maps `/data`.
- env vars configure token, org file, and sqlite path.
- container starts and exposes configured port.

* milestone 2: android local capture
** TODO create android project
*** acceptance
- kotlin android app builds.
- jetpack compose enabled.
- min sdk is reasonable for current personal device.
- app id is stable, e.g. `me.hgsky.phonecapture`.
** TODO build capture screen
*** acceptance
- app opens to multiline text box.
- keyboard opens automatically.
- note/todo control exists.
- tags field exists.
- save button exists.
- save and close affordance exists.
** TODO implement local room database
*** acceptance
- capture entity has id, created_at, kind, body, tags, device, status, synced_at, and last_error.
- saving creates pending row.
- pending captures survive app restart.
** TODO implement capture id generation
*** acceptance
- id format is stable and readable, e.g. `phone-yyyymmdd-hhmmss-rand`.
- ids are generated client-side.
- tests or simple assertions prevent blank/duplicate ids in normal flow.
** TODO implement basic history screen
*** acceptance
- lists recent captures.
- shows pending/synced/failed status.
- failed row shows last error.
- user can retry failed/pending sync.

* milestone 3: android sync
** TODO implement api client
*** acceptance
- base url configurable in app settings or build config.
- bearer token configurable in app settings or build config.
- client can call `/health`.
- client can post capture payload.
** TODO implement manual sync
*** acceptance
- sync now posts all pending captures.
- successful posts mark rows synced.
- already-seen response marks row synced.
- failures retain pending/failed status and last error.
** TODO implement opportunistic workmanager sync
*** acceptance
- periodic sync is registered.
- sync only runs when network is available.
- worker first checks `/health`.
- worker does not block capture speed.
** TODO add simple server reachability settings
*** acceptance
- default url can be set to `http://jeeves.mother:8765`.
- user can change server url.
- user can change token.
- invalid settings do not crash app.

* milestone 4: polish and hardening
** TODO make launch path fast
*** acceptance
- app opens directly to capture field.
- no network call blocks launch.
- no history loading blocks text entry.
** TODO normalize tags
*** acceptance
- whitespace-separated and comma-separated tags both work.
- invalid org tag chars are stripped or replaced.
- duplicate tags collapse.
** TODO handle multiline notes well
*** acceptance
- first line can become note heading if body is multiline.
- full body is preserved under heading.
- todo body remains usable as a single todo heading, with extra lines under it if present.
** TODO add basic logs
*** acceptance
- server logs accepted capture id.
- server logs duplicate capture id.
- server logs rejected payload without dumping secrets.
** TODO create backup note
*** acceptance
- readme documents which paths need backup.
- readme documents restore behavior.

* milestone 5: optional v1.5
** TODO add android share target
*** acceptance
- sharing text to app opens prefilled capture.
- user can save as note or todo.
** TODO add home screen quick capture widget
*** acceptance
- widget opens capture screen quickly.
- does not require sync to work.
** TODO add recent tag chips
*** acceptance
- app shows recent tags.
- tapping chip adds/removes tag.
** TODO add edit-before-sync
*** acceptance
- pending/failed captures can be edited.
- synced captures are read-only unless explicitly duplicated.

* implementation notes for coding agents
- keep the server small and testable.
- keep org formatting in one pure function.
- do not add auth flows, accounts, or public hosting.
- do not add org parsing.
- do not write to org files from android.
- prefer boring explicit settings over clever discovery.
- if a design choice risks sync conflicts, do the simpler append-only thing.
