# Handoff: state of the work

Living document, rewritten in place (never a second copy). A new orchestrator session reads CLAUDE.md, then this.

## 1. Where things stand
- `main` at `ad35231` (portless Android fixtures after D-124; on top of D-124's `a86ad24` server and contracts, `4852803` bundle, `038c603` Android with the pinned-root template, SPEC v0.22 `cce3e4e` and `ac17b41`) plus the SPEC v0.23 docs commit from `agent-docs-v023` once it lands. `origin/main` (Gitea) at `038c603`: `ad35231` is not pushed yet.
- **Kvitt host name** (owner decision 2026-10-19): `kvitt.suorra.duckdns.org`, a subdomain of the owner's DuckDNS family domain `suorra.duckdns.org`; NPM issues its Let's Encrypt certificate; `KVITT_PUBLIC_HOST=kvitt.suorra.duckdns.org`, so `KVITT_PUBLIC_URL=https://kvitt.suorra.duckdns.org` (port 443, D-124). It is in `infra/pi/.env` (`KVITT_PUBLIC_HOST`) and `android/local.properties` (`kvitt.publicHost`), both git-ignored. SPEC §10.1 and §10.5.1 point here.
- **NPM proxy host** for `kvitt.suorra.duckdns.org` is Online with a Let's Encrypt certificate (owner, 2026-10-19). From the Mac, `https://kvitt.suorra.duckdns.org/health` presents a valid certificate and returns NPM's 502, as expected while the Kvitt Pi is not running. The router needs no new rule: external TCP 443 already forwards to the Home Assistant Pi (owner confirmed, D-124).
- **Gitea secret diagnosis** (the temporary "Diagnose secrets" step, `dd07ca4`): the user-level secret `babymonitor_cicd` reaches the repository (length 40), `kvitt_cicd` has length 0, so the secret is not stored under that name on the `jacobh2` account. The owner is fixing the name (§3 item 1).
- History rewrite and first push, 2026-10-18 (owner authorised): superseded PNG versions were dropped from the whole history (no LFS), the current goldens and UX mock-ups restored in `18c527f`; pack 45 MiB; `origin/main` pushed at `18c527f`. A bundle of the pre-rewrite history (`kvitt-pre-rewrite.bundle`) is kept outside the repository, in the orchestrator's scratchpad. Every commit from M2b on got a new hash; the oxipng pass (`7c453d8` before the rewrite) no longer exists as a commit (it only touched PNGs). SPEC, `docs/decisions.md`, this file and `prompts/README.md` cite the rewritten hashes since v0.18 (`7c453d8` stays as the oxipng pass's name; `docs/validation/ac-coverage.md` keeps its pre-rewrite hashes verbatim); since v0.19 the plans cite rewritten hashes too (eight pre-rewrite hashes in `PLAN-*.md` replaced by the commit with the same subject); `docs/spikes/pi-image-arm64.md` and the READMEs had none stale. For any other old hash, find the commit by its subject with `git log --oneline --grep`.
- History (rewritten hashes): `5e1be38` plans and prompts, `c885aba` M2c-dev, `76ee957` SPEC v0.3, `c277ee3` M2b, `06f48ef` M2a, `6dce4c7` SPEC v0.4, `7869ec4` M3, `8f0e156` M5, `853c038` SPEC v0.5, `15056dc` M4, `d9dd584` SPEC v0.6, `50339ae` M9, `86e08a1` SPEC v0.7, `aa765bb` M12a, `d39eb2c` SPEC v0.8, `b09f322` M12c, `6eaccec` M12b, `0006bd7` UX Kalas categories and tokens, `6da6b1b` UX sprint U2, `e676812` SPEC v0.9, `557af7e` M12d, `7730a31` M6, `9ee67d4` SPEC v0.10, `a41f240` and `6453932` app wiring before M8, `1ea752c` M7a, `ea7d494` M7e, `7380e50` M7d, `0e1d99d` M7b, `0b140aa` M7c, `c4ab35f` M7f, `b24c8b5` M6b, `f4dc10c` SPEC v0.11, `3dda414` M7g, `cb832a7` and `3d9eea8` M8, `6159e18` SPEC v0.12, `8c60715` M12e, `b7b7483` M12e launcher icon, `51d6ff8` SPEC v0.13, `a312758` Vico removal, `f56dcbe` FCM `fid`, `3e6c337` Pi image arm64 check, `e2dba84` SPEC v0.14, `328c466` M8b, `6eb3f85` `FcmMessageBody.fid`, `bfde12c` SPEC v0.15, `75b549f` M8c goldens, `a0c25b0` M8c licences row, `c30a49e` R8 release build, `bacbd18` M8d, `bfc3acb` SPEC v0.16, `2476667` M2c-pi bundle, `a59abeb` M8e, `b4d9467` Dockerfile `CARGO_BUILD_JOBS`, `956908a` M8f, `1328afe` chips cleanup, `400eac9` SPEC v0.17, `18c527f` goldens restored after the rewrite; then `2fac1ec` to `e70fe0d` infra overhaul, `8660b7f` server gap pass, `7fb86f5` infra security, `dc7a296` to `a0259ab` M12f, `8103dae` to `b985ce9` server overhaul, `48fe119` SPEC v0.18, `e4e6e5d` to `c582363` Android overhaul, `3ef2c15` SPEC v0.19, `96e4cbd` APK download rate limit (D-119), `481889a` SPEC v0.20, `f1abb0d` `cargo audit` in the server gate, `4f69ae0` Gitea login in the run line, `d05f13a` Pi stack behind NPM, `62f5279` and `9231a1d` infra README for NPM (D-120), `d090c6c` Android host property (D-121), `4bcff2c` SPEC v0.21, `dd07ca4` temporary workflow diagnostic step, `4a4e45f` S-22's release server and `4b1ae0c` `publish-apk.sh` host (D-122), `c9abd24` and `e381e37` server host defaults and OpenAPI `{host}` (D-123), `ac17b41` `install.sh` step number, `cce3e4e` SPEC v0.22, `a86ad24` server and contracts on port 443, `4852803` bundle on port 443 (D-124), `038c603` Android on port 443 and the pinned-root template, `ad35231` portless Android fixtures.
- Landed since SPEC v0.22 (recorded in v0.23):
  - Port 443 (D-124, owner decision 2026-10-19): Kvitt is served at `https://<host>` with no explicit port, because NPM listens on 443 and selects by host name; the router's existing external-443 forward to the Home Assistant Pi serves Kvitt, no 8443 rule. Server and contracts (`a86ad24`): OpenAPI server `https://{host}`, E-7 and E-12 examples without a port, `tools/contracts-check.py` follows. Bundle (`4852803`): `KVITT_PUBLIC_URL=https://${KVITT_PUBLIC_HOST}`, health checks through NPM on 443, README step 7 "Router: no new rule", the APK-abuse stop-gap is disabling Kvitt's proxy host in NPM. Android (`038c603`): `releaseServerUrl(host)` = `https://<host>` (`RELEASE_SERVER_PORT` removed), the AC-2.6 intent filter without a port (matches every port, so an old `:8443` link still opens S-1 with the server it names), invite-link parsing drops `:443` and `:80`, 28 S-1 goldens on `https://kvitt.example.org`.
  - Portless Android fixtures (`ad35231`, D-124): `android/README.md`, the `AppBuildInfo` and `AboutRepositoryImpl` comments, the S-21 and S-22 fake scenarios and the `:data` test fixtures without `:8443`; 30 goldens re-recorded (6 S-21 invite-created, 24 S-22). What is left of `8443` in `android/` is deliberate: tests that an old `:8443` link still opens S-1 and that a typed port survives.
  - Pinned-root template (`038c603`, no decision): with `kvitt.tls.pinnedRoot=true` the build generates the pinned-root network security config from `android/app/src/releasePinnedRoot/network_security_config.xml` with the domain `kvitt.publicHost` and stops with a message while `android/app/src/release/res/raw/kvitt_root_ca.crt` is not committed (SPEC §8.5, §10.5.3). The old host name is out of that config and of the S-1 fixture.
- Landed since SPEC v0.21 (recorded in v0.22):
  - D-121 follow-ups (`4a4e45f`, `4b1ae0c`; D-122): `AppBuildInfo.releaseServerUrl` from `RELEASE_SERVER_URL`; S-22 shows the paired server, before pairing the build's release server; `DataModule.DEFAULT_SERVER_URL` removed; fakes and tests on `https://kvitt.example.org:8443` (30 S-21/S-22 goldens re-recorded); `infra/publish-apk.sh` reads `KVITT_PUBLIC_HOST` from `infra/pi/.env` (refuses missing, `CHANGE_ME`, a URL, the old name) and passes `-Pkvitt.publicHost`.
  - Server host defaults (`c9abd24`, `e381e37`; D-123): `KVITT_PUBLIC_URL` required (every command exits 1 without it, before opening the database); `KVITT_TRUSTED_PROXY` defaults to `none`; OpenAPI server `https://{host}:8443` (portless since D-124) with variable `host` (default `kvitt.example.invalid`); E-7 and E-12 examples on `kvitt.example.invalid`; `tools/contracts-check.py` follows. 276 server tests.
  - `install.sh` names the NPM proxy host as README step 6 (`ac17b41`, no decision).
  - Temporary "Diagnose secrets" step in `.gitea/workflows/build-images.yaml` (`dd07ca4`, no decision), to be removed once the login failure's cause is known.
- Landed since SPEC v0.20 (recorded in v0.21):
  - `cargo audit` in the server gate (`f1abb0d`, no decision): the gate is `cargo fmt --check && cargo clippy --all-targets -- -D warnings && cargo audit && cargo test`; the pre-commit hook runs `cargo audit --no-fetch` only when `server/Cargo.lock` or a server `Cargo.toml` is staged. First run: 0 advisories over 319 crates.
  - NPM rework (`4f69ae0`, `d05f13a`, `62f5279`, `9231a1d`; D-120): TLS terminates in the owner's Nginx Proxy Manager on the Home Assistant Pi; Caddy, cert-sync, the Caddyfile, the HA SSH key and the router forward to the Kvitt Pi are gone. Kvitt gets its own host name `KVITT_PUBLIC_HOST` (owner-chosen; a DuckDNS name is being set up), because `icehack.asuscomm.com` is NPM's proxy host for Home Assistant. Router external 8443 → HA Pi 443 (replaced by the existing 443 forward, D-124). The server publishes 8080 on the Kvitt Pi's LAN, `KVITT_TRUSTED_PROXY=${HA_HOST}` (NPM's IPv4, checked by `install.sh`). SPEC §10.5 rewritten (NPM proxy host, the Custom Nginx Configuration with D-117's headers and the `/i/` log exclusion, fallback: no LAN path for release builds). Rehearsed on the Mac: `nginx -t` against NPM v2.16.0 templates, 21 checks of the server behind nginx passed. The Gitea login interpolates the secret in the `run` line (the env form came through empty on act_runner 0.6.1).
  - Android host property (`d090c6c`, D-121): `kvitt.publicHost` (Gradle property, else `android/local.properties`, else `kvitt.example.invalid`), `BuildConfig.PUBLIC_HOST`, the manifest placeholder `publicHost`, `RELEASE_SERVER_URL`, `@ReleaseServerUrl` in `:feature:onboarding`. 944 Android tests.
- Landed since SPEC v0.19 (recorded in v0.20):
  - APK download rate limit (`96e4cbd`, D-119, security review L-3): E-6 `GET /apk/files/{file_name}` at most 10 requests per minute per client IP in its own window, not counted against the 60 of the other unauthenticated endpoints; a 404 counts; 429 `rate_limited` with `Retry-After`; E-5 and E-4 stay on the 60; unit and integration tests.
- Landed since SPEC v0.18 (recorded in v0.19):
  - Android overhaul (`e4e6e5d`, `8229ed6`, `515b60f`, `e08aaf0`, `0714242`, `a92c236`, `74b5fbd`, `c582363`; D-118): shared test support in `:core:design`'s test fixtures (`se.hagstedt.kvitt.design.testing`), `kvitt.android.screenshots` wires Roborazzi and the test libraries; `format/Failures.kt`, `format/Limits.kt`, `savedSplitLabel` in `:core:design`; dead code removed (`KvittMotion` only the seesaw spring, `KvittIcon.Description`, unused dimens and shapes); four catalog entries removed; one `CopyCategoryKeywords` task; one `configureAndroidModule`; S-7's state types in `ExpenseEditorState.kt`. Gate at landing: 941 tests, no golden changed. Release APK 10.46 MB.
- Landed since SPEC v0.17 (recorded in v0.18):
  - Infra overhaul (`2fac1ec`, `61f92c8`, `fc6126c`, `b647faf`, `e70fe0d`; no decision): `tools/gradle-lock.sh` shared by `gradle-serial.sh`, `clean-builds.sh` and `infra/build-images.sh`; the pre-commit hook runs through `gradle-serial.sh` with JDK 25 on `PATH` (hooks reinstalled in `main` after `e70fe0d`); `install.sh` keeps the deployed `KVITT_TAG`; `--provenance=false` on buildx pushes, the workflow token through env; `RCLONE_REMOTE` dropped from the dev env.
  - Server gap pass (`8660b7f`, D-113): `kvitt-server invite-partner` (0 ok, 2 household full, 3 no admin), so a scripted partner needs no second admin device; `push sent` info line; CLI tests (`invite-partner`, `migrate`, `healthcheck`, SIGTERM drain); `tools/contracts-check.py` 134 checks.
  - Infra security (`7fb86f5`, D-117): Caddy log redaction of `/i/<code>` and query strings, CSP and three more response headers, Caddy non-root (uid 10002, read-only, caps dropped), `/certs` 0750, dev stack mounts only the FCM key, `/opt/kvitt/deployed-digests` with a WARNING on change, `kvitt_cicd` with `write:package` only, the plain root key (old variant B) not acceptable.
  - M12f (`dc7a296`, `5b2ed37`, `2bd6b58`, `c366fbd`, `a0259ab`; D-109 to D-112, D-116): S-16 lost version read-only, S-22 "<version> (schema <n>)" from `/health`, `SettlementRepository` returns null instead of throwing, E-17 retry after each successful sync, invite links dropped while paired, private notifications on the lock screen, `localeFilters` en/sv, `:data` tests (429, D-040, WorkManager via `work-testing`), the home/account screenshot harness fix (stale `sv_dark` goldens re-recorded), 19 unused string keys removed (`strings.csv` 562 rows). Gate at landing: 941 tests. Release APK 10.0 MB.
- Validation reports (SPEC §11.4): `docs/validation/ac-coverage.md` (taken at `956908a`, `ed1b130` before the rewrite): 270 rows, 260 Done, 5 Partial, 1 Missing, 4 device-only; feature complete in code, not yet against §4's acceptance rule; its S-16 and S-22 mismatches are fixed by M12f. `docs/validation/security-review.md` (taken at `18c527f`): Critical 0, High 1, Medium 3, Low 10, Info 8; L-6 kept (D-116), L-7 fixed (D-116), L-1, L-2, L-5, L-9, M-2 fixed (D-117), L-8 fixed (`e70fe0d`); H-1 (`725901c`, D-115), M-3 (`baa5806`) and L-4 (`b985ce9`, D-114) fixed by the server overhaul; L-10 left as the spec says, decision pending (§4). Owner answers of 2026-10-19: M-1 no (backups stay unencrypted, rclone keeps the `drive` scope; accepted risk in SPEC §8.1 and §8.7), L-3 accepted and fixed (`96e4cbd`, D-119), the 16 MP and 512-character limits (D-114) confirmed; M-2's remaining question (the Home Assistant SSH key form) is moot with the NPM rework (D-120) and closed; D-120 also moves L-1 and the headers to NPM, makes L-2 moot, reverses the L-8 fix and replaces I-5's check with a conntrack check (dated notes in the review, SPEC §11.4). H-1 is fixed (`725901c`).
- Server overhaul (landed on `main` `8103dae` to `b985ce9`): shared helpers and one test harness, clippy pedantic wins; H-1 rate limiter (`725901c`, D-115), pictures at most 16 MP and 64 MB decoded (`baa5806`, D-114), `fcm_token` at most 512 characters (`b985ce9`, D-114); shared row inserts, invite creation and CLI helpers, `tests/common/` harness, synchronous `tasks::start`; 268 server tests; all crates at their latest versions. Recorded in SPEC v0.18.
- In flight:
  - This docs pass (`agent-docs-v023`: SPEC v0.23, D-124, HANDOFF, `prompts/README.md`).
  - Gitea Actions: the login step interpolates the secret in the `run` line (`4f69ae0`); the diagnosis found `kvitt_cicd` empty (§1); the owner is storing it under the right name (§3 item 1).
- Earlier outcomes (details in SPEC §11.2, §11.3 and `docs/decisions.md`): M8 end-to-end test passed on the owner's S26 against the dev server on 2026-10-18 (pairing, scripted partner, offline expense synced, push by `fid` delivered); M8b to M8f UI fixes; the M2c-pi bundle `infra/pi/` (D-103 to D-106, owner checklist in `infra/README.md` "Pi: what the owner does"); release builds R8-shrunk and signed (alias `kvitt`, RSA 4096, v2).
- Compatibility: an APK from M12e on cannot pair or list devices against a pre-M12e server, so the server is rebuilt and redeployed before a new APK is installed (SPEC §14.8). The dev server already runs schema 3.
- Remote: `origin` on Gitea, SSH key works; pushed at `038c603`. The owner created a Gitea secret meant as `kvitt_cicd` (not found under that name, §1) and the Drive token (`infra/secrets/rclone.conf`, `[gdrive]`; folder id in `.env` as `RCLONE_FOLDER_ID`). Unused on the Mac since D-120: `infra/secrets/ha_ssh_key` and `ha_ssh_key.pub` (git-ignored; may be deleted).
- Both gates exist: Android `tools/gradle-serial.sh check` (from `android/`), server `cargo fmt --check && cargo clippy --all-targets -- -D warnings && cargo audit && cargo test` (from `server/`, `cargo audit` since `f1abb0d`). Both green on `main` as far as reported (Android 944 tests at `d090c6c`, one more test in `4a4e45f`; server 276 tests at `c9abd24`).
- Importer: the dry run of 2026-10-18 reconciled on both real files (Vardag 1746 rows, Hemma 37 rows, 0 unmapped). The CSV files stay in `export/` (git-ignored).
- Development stack (M2c-dev): running on the Mac at `http://192.168.1.210:8080`, database at schema 3, data kept; backups `infra/dev/backups/kvitt-20261018T093143Z.sqlite.gz` and `kvitt-20261018T130443Z.sqlite.gz` (git-ignored). On this Podman setup run `infra/dev/up.sh --down`, then `infra/dev/up.sh`, to swap in a rebuilt image. Since `7fb86f5` `up.sh` copies only `fcm-service-account.json` into `infra/dev/secrets/` (git-ignored). The owner's phone is paired with it; a scripted partner exists (tokens held by the orchestrator outside the repo). Firebase project `kvitt-1337` with apps `se.hagstedt.kvitt` and `se.hagstedt.kvitt.debug`; service account `kvitt-fcm`.
- Installed on the owner's phone (SM-S942B): the debug app `se.hagstedt.kvitt.debug`, paired against the dev server; the release app `se.hagstedt.kvitt`, rebuilt with the host `kvitt.suorra.duckdns.org` and no port (D-124) and installed 2026-10-19; release pairing waits for the Kvitt Pi (release builds require `https`, AC-2.8; §3 item 3).
- Disk: the MacBook had about 72 GB free during the v0.20 docs pass (2026-10-19); run `tools/clean-builds.sh` when it drops under about 5 GB.

## 2. Open work (one line each, with who owns it: agent or owner)
- Land `agent-docs-v023` (orchestrator): SPEC v0.23, D-124, HANDOFF, `prompts/README.md`, the S-1 TalkBack line of `docs/ux/design-spec.md`.
- Closed by D-124, `038c603` and `ad35231`: the server's and the bundle's `:8443`, `RELEASE_SERVER_PORT`, the intent filter's port, the pinned-root config's old host name and the stale "pinned Caddy root" comment, `OnboardingStates.kt`'s `GOLDEN_SERVER`, the `:data` comments, the `FakeScenarios` and `SettingsScenarios` fixture URLs, `android/README.md`.
- Push `ad35231` and the v0.23 docs commit to `origin` (orchestrator).
- Remove the temporary "Diagnose secrets" workflow step (`dd07ca4`) once a run passes the login (agent, after §3 item 1).
- Possible firewall rule on the Kvitt Pi limiting access to port 8080 to the HA Pi (`HA_HOST`); not done, not decided (owner).
- `PLAN-M2c-pi.md` is superseded where it names Caddy and cert-sync (note at its top); SPEC §10 and `infra/README.md` are current.
- Restore drill AC-18.2 (`docs/validation/restore-drill.md`, M10; the one Missing row of the AC-coverage audit).
- AC-18.1, AC-20.1 and AC-16.3 shown on the Pi and the phones (M2c-pi run, M10).
- A `KvittWorkerFactory.createWorker` test (Android agent, no plan yet).
- Security review L-6: an S-1 design state if the owner wants a confirm step for an unusual server (OQ-6, default not in v1; owner, §4).
- Security review L-10: `forbidden` or `not_found` for the other user's device id (owner decision, §4).
- State-class naming: `*Ui`, `*UiState` and `*State` are mixed across features; needs a decision if a convention is wanted (owner; no plan).
- Unverified risk: the workflow pushes a git tag; whether that re-triggers the path-filtered workflow is not known (watch the next runs).
- Owner runs the Pi bundle on the Kvitt Pi (§3 item 2); the checklist is `infra/README.md` "Pi: what the owner does" (nine steps; NPM at step 6 is done, the router at step 7 is a check only, D-124).
- Plans (SPEC §11.2 v0.23), in dependency order; prompt `prompts/<id>.md`:
  - M1, M2a, M2b, M2c-dev, M3, M4, M5, M6, M6b, M7a to M7g, M8 (phone test passed), M8b to M8f, M9, M12a to M12f, U1, U2, R8 release build, M2c-pi bundle and its NPM rework, server gap pass, infra overhaul, infra security, the server overhaul, the Android overhaul, the APK download rate limit, `cargo audit`, the Android host property and its follow-ups (D-122), the server host defaults (D-123), port 443 (D-124): landed.
  - Next: the owner runs the bundle on the Kvitt Pi when he moves over (D-100; the image must carry the H-1 fix, which every image since `725901c` does); M10 First release after it (keystore per §10.6, D-101); M11 Import history after M9 and M10 (procedure §10.8 "Production run", D-025; each run must reconcile, D-045).

## 3. HUMAN steps pending (relay in chat)
1. Gitea secret: in Gitea, the user menu, Settings, Actions, Secrets, add the secret `KVITT_CICD` with the registry token (`write:package`). Then the repository, Actions, "Build Kvitt images", "Run workflow". Report: did "Log in to Gitea Container Registry" pass (yes/no), and did the run finish (yes/no; if "Tag and Push Version" failed with a permission error, say so).
2. Pi: provision the Kvitt Pi and install Docker (`infra/README.md` "Pi: what the owner does" steps 1 and 2); fill `infra/pi/.env` (`HA_HOST`, `KVITT_PI_HOST`, `KVITT_PI_SSH_USER`, `KVITT_TAG`); copy the bundle to the Pi; run `install.sh`. Expected: on the phone, `https://kvitt.suorra.duckdns.org/health` shows `"status":"ok"` (yes/no).
3. Release app pairing, after item 2: run `kvitt-server bootstrap` on the Pi (`/opt/kvitt/bootstrap.sh`) and pair the release app with that code (relayed in chat with the exact screen labels when the time comes).

## 4. Owner questions (asked, unanswered)
- OQ-6 (SPEC §12): a confirm step on S-1 for an unusual server; default "not in v1".
- Security review L-10: should a member get `not_found` instead of `forbidden` for a device id of the other user (hides whose it is)? As built and as the spec says: `forbidden`.
- State-class naming (`*Ui`, `*UiState`, `*State` mixed): fix one convention, or leave as built?
- `write:repository` for the registry secret, only if the workflow's tag push fails (§3 item 1).
- Answered 2026-10-19: Kvitt's host name is `kvitt.suorra.duckdns.org` (§1); Kvitt on port 443 through the existing router forward (D-124).

## 5. Paused (waiting on something outside the repo)
- Nothing.

## 6. Numbering
- Decisions: D-001 to D-124 used, except D-008 and D-009 (never used); nothing reserved. Next free: **D-125**.
- Spec version: v0.23 written; next **v0.24**.
- Server schema version **3** (migration 0003); next **4**. Room schema version **1** (`android/data/schemas/se.hagstedt.kvitt.data.db.KvittDatabase/1.json`); next **2**. Both unchanged by v0.23.
