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 96e4cbd (the APK download rate limit, D-119, landed after the SPEC v0.19 docs commit 3ef2c15) plus the SPEC v0.20 docs commit from agent-docs-v020 once it lands. origin/main (Gitea) at 96e4cbd: everything up to the rate limit is pushed.
• History rewrite and first push, 2026-10-18 (owner authorised): superseded PNG versions were dropped from the whole history (no LFS), the current goldens and UX mock-ups restored in 18c527f; pack 45 MiB; origin/main pushed at 18c527f.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).
• 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 " (schema )" 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. H-1 must be fixed before port 8443 is opened.
• 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:
  • NPM rework (D-120 reserved, agent running): the owner runs Nginx Proxy Manager on the Home Assistant Pi, and NPM renews the Let's Encrypt certificate for icehack.asuscomm.com. Caddy and cert-sync are replaced by an NPM proxy host that forwards to the Kvitt Pi's server on LAN port 8080, so TLS terminates in NPM, the Kvitt Pi's compose stack loses caddy and cert-sync, and the infra/pi/ bundle and its owner checklist change. Security review M-2 (the HA SSH key form for cert-sync) becomes moot and is closed. SPEC §10.5 and the other Caddy and cert-sync text are rewritten when D-120 lands (a docs pass records it; next free decision D-121). Open assumptions are §3 item 3.
  • This docs pass (agent-docs-v020: SPEC v0.20, D-119, HANDOFF, prompts/README.md).
  • cargo-audit in the server gate: the orchestrator is installing cargo-audit on the Mac; an agent adds it to the gate after the install.
• 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 96e4cbd. The owner created the Gitea secret kvitt_cicd and the Drive token (infra/secrets/rclone.conf, [gdrive]; folder id in .env as RCLONE_FOLDER_ID); the cert-sync key infra/secrets/ha_ssh_key exists (all git-ignored). The first push triggered the Gitea Actions workflow; its result is the owner's §3 item 1.
• Both gates exist: Android tools/gradle-serial.sh check (from android/), server cargo fmt --check && cargo clippy --all-targets -- -D warnings && cargo test (from server/). Both green on main as far as reported.
• 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, with the build whose checks are §3 item 2; the release app se.hagstedt.kvitt, installed 2026-10-19, not yet paired (its checks are §3 item 2 as well).
• 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-v020 (orchestrator): SPEC v0.20, D-119, HANDOFF, prompts/README.md.
• 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).
• Tooling: cargo-audit in the server gate (agent, after the orchestrator's install on the Mac, in flight).
• 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 first runs).
• Land the NPM rework (D-120) when its agent reports, then a docs pass records D-120 and rewrites SPEC §10.5 and the Caddy and cert-sync text (orchestrator).
• The owner's answers to the phone checks of §3 item 2 (debug app checks; release app pairing with a device invite the orchestrator provides).
• Owner runs the Pi bundle on the Kvitt Pi: deferred by the owner on 2026-10-19 ("when it makes sense to move over to the Pi"); the bundle and its checklist are rewritten by D-120 first; record the router-forward answer in infra/README.md then (the cert-sync key-form question is closed).
• Plans (SPEC §11.2 v0.20), 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, server gap pass, infra overhaul, infra security, the server overhaul and the Android overhaul: landed.
  • Next: a server image with the H-1 fix before the router forward; the NPM rework (D-120) reshapes the Pi bundle; the owner runs it on the Kvitt Pi when he moves over (D-100, deferred); 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, the repository, Actions: did the run "Build Kvitt images" triggered by the first push succeed (yes/no), and how long did it take? Parked by the owner ("come back to it"). If the run's tag push failed with kvitt_cicd limited to write:package: may write:repository be added (yes/no)?
2. Phone checks, answers pending (yes/no each):
   1. Debug app (se.hagstedt.kvitt.debug): screen switches are instant, with no fade or slide; Inställningar, Om Kvitt shows the server version as "… (schema 3)"; the recurring editor shows Konto, Betalt av, Delning as three fixed rows.
   2. Release app (se.hagstedt.kvitt, installed 2026-10-19): it opens to "Para ihop" without a crash; then pair it with the device invite the orchestrator provides; Home shows "Test"; add one expense and watch it sync.
3. NPM questions (for D-120; the agent proceeds on the assumptions): is icehack.asuscomm.com already a proxy host in Nginx Proxy Manager for another service (assumed free)? Does the router forward external 8443 to NPM's 443 or to a dedicated NPM port (assumed 443)?
4. Pi checklist, later: deferred by the owner ("when it makes sense to move over to the Pi"). The steps of infra/README.md "Pi: what the owner does" are rewritten by D-120 (no cert-sync key, the router forward goes to NPM) and relayed in chat when the owner moves over.

4. Owner questions (asked, unanswered)

• §3 item 1: the workflow result and duration (parked), and write:repository if the tag push failed.
• §3 item 2: the debug and release app checks.
• §3 item 3: the two NPM questions (assumed: icehack.asuscomm.com free in NPM; external 8443 to NPM 443).
• 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?

5. Paused (waiting on something outside the repo)

• Nothing.

6. Numbering

• Decisions: D-001 to D-119 used, except D-008 and D-009 (never used); D-120 reserved by the running NPM agent. Next free: D-121.
• Spec version: v0.20 written; next v0.21.
• 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 v0.20.
• Sync protocol 1, push payload 1.

7. How the work is run

See CLAUDE.md › Orchestration. HUMAN steps in reports are relayed in chat by the orchestrator; the owner does not read them in files.
