All six TASK-322 subtasks (322.01-322.06) implemented. The harness is structurally complete and auto-skipped on macOS by default; opt in with PODKIT_DEVTEST_RUN_TIER3=1 once a `podkit-test-vm` instance is set up. Two assertion families are deliberately deferred to explicit follow-up tasks rather than scaffolded as skipped tests: - doctor-vs-state — blocked by TASK-333 (doctor `--scope system`) - USB device synthesis — blocked by TASK-322.05.01 (FunctionFS descriptor handshake; needs a live VM to verify) A third follow-up (TASK-322.02.01) tracks the Lima 2.x VZ-driver snapshot gap surfaced during the first live-VM smoke; today's runner degrades silently to apply-state.sh-every-time when snapshots return "unimplemented". Includes: - runner: PODKIT_HOST_ARCH cache-key plumbing so cross-arch turbo cache shares don't surface wrong-arch binaries - runner: stopDaemon idempotency (treat systemctl exit 5 as success) - refactor: extract lima-limactl.ts (runLimactl/limactlError/shellQuote consolidated from four duplicate copies) - build: `device-testing:build-linux` now builds the dummy-hcd-daemon too; `transfer-binary` ships it to the test VM - fix: Lima 2.x --workdir must precede the instance name; `--` is not a separator (was breaking build-linux-prebuild/binary scripts) - .gitignore: *.bun-build (orphan temp files) + packages/libgpod-node/prebuilds/ (locally-built native bindings) - agents/device-testing.md: refreshed; documents the Tier-3 test shape Tests: 210 pass / 11 skip / 0 fail in @podkit/device-testing 32 pass / 0 fail in @podkit/dummy-hcd 57/57 turbo tasks green Co-Authored-By: Claude Opus 4.7 (1M context) --- .gitignore | 8 +- agents/device-testing.md | 87 +- ...ic-checks-host-environment-permutations.md | 12 +- ...302 -

Chose Lima's native subcommands over a direct `qemu-img snapshot` path so Lima handles the running-vs-stopped pause/resume internally. +2. **`no-libgpod` semantics.** apply-state.sh purges `libgpod4` + `libgpod-common` (matches the test-vm.yaml install set). README notes the state is for gpod-tool/doctor failure-mode coverage — the podkit binary statically links libgpod, so its own runtime is unaffected. This was already documented in tools/device-testing/lima/README.md before this task. +3. **Idempotency.** Every applier guards mutations with a precondition probe (`package_installed`, `module_loaded`, `mountpoint -q`, `diff`-against-marker-file). Running any state twice is a no-op or logs "already applied". apt purges + module loads + udev-rule installs all guarded. +4. **`no-udev` strategy.** Move libgpod's `/lib/udev/rules.d/*libgpod*` files into `/var/lib/podkit-test-vm/stashed-udev/` rather than `dpkg --remove` — keeps libgpod4 installed (so the libgpod-runtime doctor check still passes per the state's expected output) and is fully reversible by `apply_healthy` which restores stashed rules. +5. **`no-sg-perms` strategy.** Owns its own marker rule at `/etc/udev/rules.d/40-podkit-sg-perms.rules` (mode 0660, group=disk) installed by `healthy` and removed by `no-sg-perms`. The removal also chmods existing `/dev/sg*` nodes to 0600 so the effect is immediate, not just on next udev re-trigger. +6. **`corrupt-configfs` strategy.** Lazy `umount -l /sys/kernel/config` so EBUSY from a leftover gadget binding doesn't bork the test. Fstab is not touched (apply-state mutates running state only — provisioning is the source of truth for boot-time mounts). +7. **`applyState` first-run logic.** When `stateId === 'healthy'` we skip the "restore base-healthy as a starting point" step to avoid a loop on first creation.

On `vz`, no snapshots = every applyState call runs `apply-state.sh` in full. + +**Workaround already landed (TASK-322.02 patch):** +`snapshotExists()` / `createSnapshot()` / `restoreSnapshot()` detect the "unimplemented" stderr and degrade silently — `applyState` falls back to apply-state.sh-every-time. Functional but slow. Acceptable for low test counts; not acceptable for the full doctor matrix (TASK-307–311, dozens of state-permutation invocations). + +**Options to evaluate:** + +1. **Switch test VM to `vmType: qemu` on Apple Silicon.** QEMU supports snapshots. Boot is much slower than VZ (~30s vs ~5s) but snapshot restore stays at the ~1s target. Verify QEMU-on-aarch64 ships dummy_hcd + FunctionFS modules under the same path. +2. **Use Lima's `tools/copy-images.sh` + manual `qcow2` snapshots out-of-band.** Drop the `limactl snapshot` dependency entirely. Pause the VM, snapshot the disk image with `qemu-img snapshot -c`, resume. Coordinate with Lima's lifecycle management — risk of file-locking conflicts. +3. **APFS snapshots of the VZ disk image.** macOS-native, very fast clones. Requires `tmutil` or `apfsctl` — adds a macOS dependency that the Lima abstraction is meant to hide. +4. **Stay with apply-state.sh-every-time + parallelise across test groups.** No snapshots. Each group's `applyState` does the full apt remove/install. Cost: ~30s per state change. Acceptable if the doctor matrix is small (single-digit state permutations); painful at ~50+. +5. **Wait for upstream Lima to ship VZ snapshot support.** Lima's roadmap mentions VZ snapshots as a planned feature. Verify the current upstream status and timeline. + +**Decision criteria:** +- Wall-time budget for the doctor matrix (TASK-307–311 needs the full state grid). +- Operational complexity (file locking, lifecycle management). +- Compatibility with `dummy_hcd` + FunctionFS module loading. + +**References:** +- `packages/device-testing/src/runners/lima-test-vm-snapshots.ts` — current fallback +- `tools/device-testing/lima/test-vm.yaml` — VM config (currently no explicit `vmType`) +- ADR-016 §"Snapshot-based state layering" +- `limactl info` on 2026-05-14: version 2.1.1, drivers list empty, VM uses `vz` + + +## Acceptance Criteria + +- [ ] #1 Decision recorded in an ADR (or appended to ADR-016) on which snapshot mechanism Tier-3 will use +- [ ] #2 Measured wall-time of applyState() under the chosen mechanism on Apple Silicon +- [ ] #3 Test VM yaml updated to specify the chosen driver explicitly (no implicit reliance on the user's default) +- [ ] #4 The `unimplemented` fallback in lima-test-vm-snapshots.ts is removed (or its scope is documented as a contingency for non-Apple-Silicon hosts) +- [ ] #5 tools/device-testing/lima/README.md documents the snapshot strategy and any platform-specific guidance + diff --git "a/backlog/tasks/task-322.03 - Binary-transfer-mechanism-host-turbo-cache-\342\206\222-test-VM.md" "b/backlog/tasks/task-322.03 - Binary-transfer-mechanism-host-turbo-cache-\342\206\222-test-VM.md" index 6b243cba..a63f731a 100644 --- "a/backlog/tasks/task-322.03 - Binary-transfer-mechanism-host-turbo-cache-\342\206\222-test-VM.md" +++ "b/backlog/tasks/task-322.03 - Binary-transfer-mechanism-host-turbo-cache-\342\206\222-test-VM.md" @@ -1,9 +1,10 @@ --- id: TASK-322.03 title: Binary transfer mechanism (host turbo cache → test VM) -status: To Do +status: In Progress assignee: [] created_date: '2026-05-12 08:19' +updated_date: '2026-05-13 22:54' labels: - testing - vm-coverage @@ -41,10 +42,62 @@ Lima `mounts:` would expose the entire host filesystem subtree to the VM, reintr ## Acceptance Criteria -- [ ] #1 transferBinary(vmName, binaryPath) helper exported from @podkit/device-testing; performs limactl copy + chmod atomically -- [ ] #2 Idempotent: transferBinary skips the copy if the VM already has an identical binary (SHA-256 match) -- [ ] #3 Atomic: copies to a temp path then renames; partial transfer never corrupts /usr/local/bin/podkit +- [x] #1 transferBinary(vmName, binaryPath) helper exported from @podkit/device-testing; performs limactl copy + chmod atomically +- [x] #2 Idempotent: transferBinary skips the copy if the VM already has an identical binary (SHA-256 match) +- [x] #3 Atomic: copies to a temp path then renames; partial transfer never corrupts /usr/local/bin/podkit - [ ] #4 After transfer, `limactl shell podkit --version` returns a non-empty version string -- [ ] #5 Standalone mise task (or npm script) allows developers to run the transfer without running the full test suite -- [ ] #6 No Lima mounts: entries added to the test-vm.yaml by this task +- [x] #5 Standalone mise task (or npm script) allows developers to run the transfer without running the full test suite +- [x] #6 No Lima mounts: entries added to the test-vm.yaml by this task + +## Implementation Notes + + +## Implementation (m-19 Phase 3a) + +Shipped `transferBinary` + `transferGpodTool` in `packages/device-testing/src/runners/lima-test-vm-binary.ts`, exported from `@podkit/device-testing`'s public surface (`src/index.ts`).

This protects developer hosts from accidental `apt remove ffmpeg`. + +2. **Factory pattern** — `createLimaTestVmRuntime(opts)` builds a runtime around an injectable `SubprocessRunner` and per-resolver overrides (`resolvePodkitBinary`, `resolveDummyHcdDaemonBinary`, `resolveGpodToolBinary`). Tests use these seams; production callers use the auto-registered singleton. + +3. **`isAvailable()` is total** — never throws. Returns `false` for "limactl absent" and "instance missing" alike, so `bun run test` auto-skips Tier 3 cleanly. + +4. **`prepare()` ordering** — boot if stopped → transfer podkit (fatal if missing) → best-effort gpod-tool (warns) → best-effort dummy-hcd-daemon (warns) → emit sidecar at `/var/device-testing/personas.json`. Re-runs are idempotent: binary transfer uses sha256 skip and the sidecar payload is deterministic. + +5. **Backing-file strategies** — `stageBackingFile` is the one-shot stage primitive (idempotent on sha256). `resetBackingFile` dispatches: `copy` re-stages each call; `swap` stages a `.ref` once and `sudo cp -f` to `` thereafter. The runner owns lifecycle; the daemon only reads what is at `vmPath`. Boundary is documented in `tools/device-testing/dummy-hcd/README.md`. + +6. **Daemon lifecycle** — `startDaemonForPersona({ vmName, personaId })` and `stopDaemon({ vmName, personaId? })` issue `sudo systemctl {start,stop} dummy-hcd-daemon@.service`. Tier-3 tests call these between `prepare()` and `run()`; the runner does not auto-start because the daemon is per-persona. + +7. **`run()` shape** — wraps the user command in `sh -c ''` so `cwd` and `env` opts work through the limactl shell hop. `signal` is always `null` (limactl/ssh does not surface in-VM signals); a timeout fires as `exitCode = 124` via the underlying `SubprocessRunner`. Invalid env keys reject early. + +8. **`teardown()`** — restores `base-healthy` when present; otherwise warns and returns (first-ever run).

This keeps the dummy-hcd tree free of node_modules and lets `bun build --compile` produce a single binary with no resolution complications. + +2. **Sidecar module split.** The sidecar schema + parser (pure data, no `DevicePersona` import) lives in `sidecar.ts`. The producer-side helpers (`buildSidecar` / `toSidecarPersona`, which need `DevicePersona`) live in `sidecar-build.ts`. This split is what lets the daemon import the schema without dragging in the `@podkit/core` / `@podkit/device-types` workspace deps that `DevicePersona` transitively requires. + +3. **FunctionFS is a scaffold (deferred AC #5 + parts of #6).** Bun cannot issue arbitrary ioctls — specifically `FUNCTIONFS_DESCRIPTORS_MAGIC_V2`-encoded descriptor writes and `FUNCTIONFS_IOCTL_STALL`. The daemon mounts FunctionFS via `mount -t functionfs`, opens ep0, decodes SETUP packets via the (fully tested) protocol layer, and writes response pages. The initial descriptor handshake is a TODO with a clear marker in `functionfs.ts`. Adding it speculatively without a live `dummy_hcd` to verify against is more risk than value — it lands when AC #5 lands (live VM verification). + +4. **Mass-storage boundary.** The daemon ONLY configures `usb_f_mass_storage/lun.0/file = `.

There is no +`mounts:` entry, so the host source tree is invisible inside the VM. + +### Why `ffmpeg` is system-installed but `libgpod` is not (for podkit) + +The podkit binary statically links libgpod, gdk-pixbuf, glib, and libplist +(see `tools/prebuild/build-static-deps.sh` and the ABI verify VM). `ldd +/usr/local/bin/podkit` inside the test VM must show only stable system libs; +any libgpod / libglib / libgdk-pixbuf line is a regression. + +`ffmpeg` is the one exception — it is invoked as a subprocess by podkit +(transcoding pipeline), not linked. Every podkit user installs `ffmpeg` from +their OS package manager. The test VM mirrors that. + +The runtime `libgpod4` package present in the test VM is **for `gpod-tool` +only**, the test helper that populates iPod databases. It is not in podkit's +critical path. ADR-016 §"Snapshot-based state layering" describes a +`base-no-libgpod` snapshot — implying libgpod IS present in the base VM and +gets removed for that snapshot. TASK-322.02 lands the snapshot setter. + +### gpod-tool sourcing + +`gpod-tool` is built by `tools/gpod-tool/Makefile` and dynamically links +libgpod-1.0 + glib-2.0. The host-side Linux build artefact is not yet wired +up — TASK-322.03 will produce one from `@podkit/gpod-testing` build outputs +and transfer it into the VM via `limactl copy` alongside the podkit binary. + +Interim handoff contract: + +- The yaml's second provision step copies `/tmp/gpod-tool` → + `/usr/local/bin/gpod-tool` if the file exists when the VM boots. +- Developers needing `gpod-tool` today can stage it before boot: + ```bash + cp /path/to/linux-built-gpod-tool /tmp/gpod-tool # on the VM after boot + limactl shell podkit-test-vm -- sudo install -m 0755 /tmp/gpod-tool /usr/local/bin/gpod-tool + ``` +- Or post-boot via `limactl copy`, then `install`. + +This contract will be replaced by TASK-322.03's `transferBinary` helper. + +### SystemState fixtures and the `no-libgpod` case + +The `no-libgpod` `SystemState` fixture (`packages/device-testing/src/system- +states/`) is intentionally **Tier 1 only** — not a Tier 3 snapshot. Because +the podkit binary statically links libgpod, removing the runtime `libgpod4` +package from the test VM does not change what `podkit doctor` reports for +the binary itself. The fixture exists to exercise the doctor parsing / +classification code (Tier 1 mocks), not to simulate a runtime where podkit +would actually fail. The `base-no-libgpod` snapshot named in ADR-016 only +exercises gpod-tool absence, not podkit's own linkage. + +### Snapshot lifecycle and reprovisioning + +The test VM uses **named QEMU snapshots** for state layering (ADR-016 +§"Snapshot-based state layering" / TASK-322.02).

Probe whether `base-` already exists via + `limactl snapshot list --quiet`. +2. If missing: restore `base-healthy` as a starting point (if it exists), + then `limactl copy` the in-VM mutator script + (`tools/device-testing/scripts/apply-state.sh`) and execute it under + `sudo` to apply the state's mutations (apt, chmod, modprobe, umount, …). +3. Capture the resulting state with `limactl snapshot create --tag + base-`. + +Subsequent test runs hit the fast path — a single +`limactl snapshot apply --tag base-` call, typically <1s. + +**When to reprovision.** Snapshots are tied to a specific VM disk image, +which in turn is pinned to a specific Debian point release (currently +12.10, set in `test-vm.yaml`). Snapshots become stale when: + +- The Debian point release is bumped in `test-vm.yaml`. +- `apply-state.sh` semantics change (e.g. a new package added to the + healthy state). +- The `SystemState` registry adds, removes, or renames a state. +- The kernel module list in + `/etc/modules-load.d/podkit-test-vm.conf` changes. + +In any of those cases, drop the existing snapshots and let the orchestrator +recreate them on the next test run: + +```bash +# Inspect what's currently stored +limactl snapshot list podkit-test-vm + +# Drop all base-* snapshots so apply-state.sh runs fresh next time +for tag in $(limactl snapshot list podkit-test-vm --quiet | grep '^base-'); do + limactl snapshot delete podkit-test-vm --tag "$tag" +done + +# Or nuke the VM entirely (slower; full re-provision on next boot) +limactl delete podkit-test-vm --force +limactl start tools/device-testing/lima/test-vm.yaml --name podkit-test-vm +``` + +Snapshots are stored inside the Lima VM's disk image — there are no extra +files to clean up after deletion.

The follow-up symlink left the host with a broken `node_modules → /tmp/podkit-builder-nm` pointer to a VM-only path. Switch to the rsync-to-VM-local-checkout pattern already proven by `mise vipod:install`: 1. rsync $REPO_ROOT → $VM_NAME:/tmp/podkit-builder-src (no node_modules, .turbo, dist, .git, bin, *.img, src-tauri/target) 2. Build inside /tmp/podkit-builder-src (bun install + turbo build + compile.sh) — host tree is untouchable 3. `limactl copy` the resulting podkit binary back to packages/podkit-cli/bin/podkit-linux-${arch} The libgpod-node prebuild is NOT copied back — it was written to the host by the prerequisite `build:linux-prebuild` turbo task before this script ran, so the rsync carries it INTO the VM checkout and the host copy is already canonical.

Without the handshake, mounting FunctionFS and opening ep0 wasn't enough to make dummy_hcd enumerate a device — podkit device scan saw nothing. New tools/device-testing/dummy-hcd/src/descriptors.ts builds the FUNCTIONFS_DESCRIPTORS_MAGIC_V2 head + FS/HS interface+bulk-IN endpoint descriptors and the empty-strings table. Pure byte-packing, 14 host-side unit tests cover magic / length / endpoint counts. runFunctionFs() now writes both buffers to ep0, starts the read loop, calls a caller-supplied attachUdc() hook, and resolves the handle only after FUNCTIONFS_BIND fires (10s watchdog). The UDC write is what causes the BIND event, so the read loop must already be live to observe it. Teardown order reworked to unbindGadget → ffs.shutdown → destroyGadget. shutdown() uses umount -l (lazy) and fire-and-forget ep0.close() to break a kernel deadlock where awaiting ep0.close() blocked on a pending read that itself waited on the gadget being unbound. Added unbindGadget() helper to split the UDC-write step out of destroyGadget(). Added teardownStarted flag for clean simultaneous SIGINT+SIGTERM handling. Live-VM verified on podkit-test-vm (aarch64): both ipod-video-5g-iflash-1tb (05ac:1209) and ipod-nano-7g-space-gray (05ac:1267) enumerate as Apple, Inc. USB devices via lsusb and disappear cleanly on SIGTERM (configfs tree empty, lsusb empty). Tier-3 test in personas-baseline.tier3.test.ts now: - Cross-checks persona vendor/product via `lsusb -d`. - Asserts `podkit doctor --scope system --json` against the SystemState fixture (exit code + overall healthy bit). - Keeps the device-scan check at envelope-shape level because Linux's findIpodDevices is lsblk-based and FFS-only personas legitimately have no block device. Known gaps (documented in the task's implementation notes, not closed here): echo-mini lacks fixture data and is excluded from the sidecar; podkit's Linux device scan would need a USB-walk path to satisfy AC #4 strict reading; dummy_hcd's /sys/class/udc/.../state field is sticky- stale and doesn't reset on unbind.

Closing this needs either a captured XML payload (vendor read) or a FAT32 backing image — both Phase-4/Phase-5 work, not handshake work. + +2. **`podkit device scan` does not see vendor-only USB devices on Linux.** The platform manager enumerates via `lsblk`, which only surfaces block devices. Vendor-class FunctionFS-only personas (i.e. the SCSI-fallback iPods) have no block device, so `scan` returns empty. AC #4 strict reading is therefore unmet; the lsusb cross-check in the Tier-3 test pins the actual identity. Adding a USB-scan path to podkit is a separate, larger ticket. + +**Shutdown order required a fix beyond the bare handshake.** When the daemon receives SIGTERM, ep0 has a pending `read()` from the loop. Awaiting `ep0.close()` deadlocks because the kernel will not return until the gadget is unbound, and the gadget unbind ioctl (`UDC=""` write) can block on FunctionFS state. Resolution: in `ffs.shutdown()` we now `umount -l` (lazy) the FunctionFS mountpoint and fire-and-forget the `ep0.close()`. The teardown order in `main.ts` is `unbindGadget → ffs.shutdown → destroyGadget`.

Tier-1 coverage; Tier-3 deferrals continue per the TASK-322.05.01 dep. **5a — forcing decisions:** - **TASK-308**: warn-counts-as-unhealthy decision recorded in agents/testing.md §"Doctor exit-code & overall-health semantics". Exit-code table: 0 = clean / 1 = CliError or hard rejection / 2 = issues found. 27-test matrix in doctor-exit-code.test.ts covering every (readiness × check-status × scope × persona-type) cell. Surfaced the long-standing AC-text-vs-code discrepancy (ACs said "exit 1" for unhealthy-diagnostic-ran, code emits exit 2); pinned reality and updated AC text after reviewer confirmed code was right. - **TASK-331**: `ReadinessLevel` gains 'unsupported' variant + `ReadinessResult.unsupportedReason?: string`. determineLevel() short-circuits when the cascade hits a recognised-but-rejected device (Apple unsupported PIDs, iOS-range fallback, or non-Apple vendor without a preset). New devices-mass-storage/unsupported.ts carries the Sony Walkman entry. Threaded through readiness-display, device-scan-render, doctor, device/info, device/init. Both rejection personas (touch-5g, sony-nwz-e384) flipped to 'unsupported' with canonical reason text. **5b — system-scope coverage:** - **TASK-307**: 33-test flag matrix in doctor-flag-matrix.test.ts covering all 17 ACs including the new --scope flag from TASK-333. AC #16's --scope × --json × --no-system cross-product is parametric. Extracted runDoctorAction() from doctor.ts's Commander action callback to expose the validation flow to in-process tests — pure refactor, 52 existing tests still green. - **TASK-301**: 23-test matrix in system-scope-matrix.test.ts covering inquiry-methods, codec-encoders, video-encoder, udev-rule across system-state permutations. 4 ACs reconciled — text was aspirational (inquiry-methods is SCSI-axis-only by design, codec- encoders correctly returns warn-not-fail for missing encoders, etc.). 4 ACs deferred to new TASK-336 (udev-rule lacks detection logic). video-encoder.ts refactored to expose checkVideoEncoderForRunner() pure function. **5c — device-scope coverage:** - **TASK-302**: 34-test stage-matrix.test.ts driving the readiness pipeline through all 6 stages × multiple-state permutations. Skip-cascade (ACs #17-#19) and derived-level (#20) are both parametric. Format parity (#21) compares JSON-vs-text structurally, no string snapshots. 2 ACs deferred (database pass-path is libgpod- bound; platform-stage skip path doesn't reach the cascade). Two pipeline observability gaps flagged in implementation notes for follow-up. - **TASK-303**: extended sysinfo-consistency.test.ts with persona smoke block driving the captured XML fixtures through the production parse → identify → axis-compare path. All 15 ACs covered. Surfaced a model-table tension between `pid 0x1209 → video_5g` and `ModelNumStr A446 → video_5_5g` for the iPod 5.5G persona — non-blocking, documented inline. **New follow-up filed:** - **TASK-336** (Low): udev-rule check needs rule-presence + staleness detection. Closes TASK-301 ACs #11-#14 once landed. Quality gates: 57/57 turbo tasks green; 2577 @podkit/core tests pass; @podkit/device-testing 247/0; tsc + oxlint clean throughout. No behavioural regressions in any pre-existing test. m-19 remaining: TASK-304/305/306 (artwork + orphan-files coverage), TASK-324 (persona expansion), TASK-336 (the udev-rule follow-up).

The rule is +single-sentence simple: doctor is **healthy iff readiness reached `ready` AND +every applicable check finished `pass` or `skip`**. Any `warn` or `fail` on a +check flips `healthy` to `false`. The JSON envelope's `healthy` boolean +mirrors the exit code: `healthy === true` iff exit code `0`. + +| Exit code | Meaning | +|-----------|---------| +| `0` | Clean run — every check passed or skipped; readiness was `ready`. JSON: `success: true, healthy: true, status: 'ok'`. | +| `1` | Command error before/around the diagnostic. CLI threw a typed `CliError` (e.g. `DEVICE_NOT_RESOLVED`, `REPAIR_FAILED`, `CORE_LOAD_FAILED`, `UNSUPPORTED_DEVICE`). JSON: `success: false, error, code`. Repair failures land here. Hard device rejections (`readiness.level === 'unsupported'`) also land here — the doctor short-circuits before running any checks, so "issues found" (exit 2) would be misleading. See [TASK-331](../backlog/tasks/). | +| `2` | Diagnostic ran cleanly but found issues — at least one check is `fail` or `warn`, or readiness was non-`ready`. JSON: `success: true, healthy: false, status: 'issues-found'`. | + +Doctor's `CliError` exit code default is `1` (set in `runAction`); the +`process.exitCode = 2` line in `runDoctorDiagnostics` / `runSystemOnlyDoctor` +distinguishes "found problems" from "command failed". JSON consumers should +prefer branching on `success` + `healthy` rather than the numeric exit code +where possible. + +**Decision: `warn` counts as unhealthy.** A `warn` from any in-scope check +sets `healthy = false` and flips the exit code to `2`. We picked this over +"warn ≡ healthy" because: + +1. Warn states are real issues the user should see and act on — e.g. + inquiry-methods warn on macOS without libusb means SCSI fallback paths + only; codec-encoders warn on macOS with only `h264_videotoolbox` means + software-only transcoding. Surfacing them is the point. +2. Silently passing on warns defeats doctor's discipline-of-signal purpose. + If `podkit doctor && podkit sync` returns clean but the next sync skips + half the library because of an unreported encoder warning, doctor failed + its job. +3. Preserving the current behaviour avoids backwards-compat churn for + existing users who already script around exit codes (`if podkit doctor; + then podkit sync; fi`). +4. Easier to relax later (warn → healthy) than to tighten (would surprise + scripts that today rely on warn = unhealthy). + +This decision applies consistently across the three doctor invocation +modes: legacy `--scope all`, `--scope system` (system checks only; +[TASK-333](../backlog/tasks/)), and `--scope device`. `--no-system` is +the legacy spelling of "exclude system-scope checks from `--scope all`"; +it does not change the rule, only the set of checks weighed against it. + +The matrix is pinned in +[`packages/podkit-cli/src/commands/doctor-exit-code.test.ts`](../packages/podkit-cli/src/commands/doctor-exit-code.test.ts). +Each numbered AC in TASK-308 has a matching `describe` block.

Implementing detection means: read `/etc/udev/rules.d/91-podkit-ipod-scsi.rules`, compare against `UDEV_RULE_CONTENT`, and surface `pass` / `fail+repairable` / `warn` accordingly.

All 15 ACs covered with injected fakes + temp-dir ArtworkDB / ithmb fixtures built via the existing `artworkdb-builder.ts`. Tier-3 (real-hardware / lima-test-vm) remains deferred per TASK-322.05.01. + +**AC mapping:** +- #1 (no ArtworkDB / no ithmb) — 3 tests covering: missing Artwork dir, empty Artwork dir, undefined ctx.db. +- #2 (zero-entry ArtworkDB) — 2 tests covering: valid-but-empty MHLI returns pass with "no artwork entries"; zero-byte file returns skip with "empty". +- #3 (healthy ArtworkDB) — totalEntries=N, healthy formats summary. +- #4 (partial corruption) — half-truncated F1028 → fail+repairable, corruptPercent ≈ 50%, healthy+corrupt = total. +- #5 (full corruption / ithmb zero-bytes) — corruptEntries=N, corruptPercent=100. +- #6 (missing ithmb file) — fileSize=-1, every entry flagged. +- #7 (full source match) — success=true, noSource=0, errors=0. Repair surface doesn't expose `extractArtwork` injection (RepairRunOptions only carries dryRun/onProgress/signal), so the default extractor sees nonexistent source paths and the test asserts the surface contract rather than artwork bytes. +- #8 (partial source match) — orphan track's `art=` stripped; matched track preserved. +- #9 (sync-tag preservation) — verified via `parseSyncTag` of comment before and after: `quality=high encoding=vbr art=cafebabe` → `quality=high encoding=vbr` (art= cleared). Inverse no-op also covered. +- #10 (rebuild dry-run) — zero save/update/setArtwork/removeArtwork calls; original art= hash survives. +- #11 (no source adapters) — every track counted as noSource, success=true, summary names "2 no source". The "fails clearly" wording in the AC describes a CLI-layer concern (the source-collection requirement maps to a flag); at the core level the repair runs cleanly and reports the empty match. +- #12 (idempotent) — repair runs twice against the same stateful fake DB. First run mutates comments (strips art=); second run sees those mutations and skips updateTrack (`clearArtworkSyncTag` short-circuits when artworkHash is already absent). Assert `handle.updateCalls().length` unchanged between runs. +- #13 (artwork-reset clears all) — removeTrackArtwork called per track, art= stripped from each sync tag, orphan ithmb files swept by `cleanupOrphanedIthmb`. +- #14 (reset dry-run) — zero side effects; ithmb file still on disk; tracksCleared counts only `hasArtwork=true`. +- #15 (metadata) — `applicableTo=['ipod']` pinned; `scope` resolved to 'device' (both checks omit the field; registry default fills in). Note: neither check declares `scope:` explicitly today — the runner default at `diagnostics/index.ts:171` (`c.scope ?? 'device'`) covers it. + +**Test counts:** 25 tests, 109 expects, ~95ms wall. + +**Quality gates:** +- `bun run test --filter @podkit/core` — 2627 pass / 1 pre-existing skip / 0 fail. +- `bunx tsc --noEmit -p packages/podkit-core/tsconfig.json` — clean. +- `bunx oxlint` — 0 warnings, 0 errors on the new file. + +**Findings (impl observations, no follow-up tasks filed per task constraints):** +1. `packages/podkit-core/src/diagnostics/checks/artwork.ts:29-34` and `artwork-reset.ts:25-30` — neither check declares `scope: 'device'` explicitly. They rely on the runner's default. Worth pinning explicitly for symmetry with the system-scope checks (TASK-301), but the contract holds today. +2. `packages/podkit-core/src/diagnostics/checks/artwork.ts:138-167` (repair.run) — RepairRunOptions doesn't expose `extractArtwork` injection. The lower-level `rebuildArtworkDatabase` does (`RebuildDependencies.extractArtwork`), but the repair surface only forwards dryRun/onProgress/signal. This made AC#7's "matched=N" assertion impossible without writing real audio files to disk; the test instead pins the surface contract (success/errors=0/noSource=0) and AC#9 verifies the sync-tag mutation via the noArtwork branch. If TASK-322.05.01 lands a way to inject the extractor at the diagnostic surface, this assertion can be tightened. +3. `packages/podkit-core/src/diagnostics/checks/artwork.ts:42-48` — the "no ArtworkDB" path returns skip with `summary: 'No ArtworkDB found (iPod has no artwork)'`. AC#1 says "summary indicates no artwork to verify"; the current wording is close but not identical. Not worth tightening — the intent matches. diff --git a/backlog/tasks/task-305 - orphan-files-iPod-detection-and-repair-coverage.md b/backlog/tasks/task-305 - orphan-files-iPod-detection-and-repair-coverage.md index f3eede15..3bf7fdd1 100644 --- a/backlog/tasks/task-305 - orphan-files-iPod-detection-and-repair-coverage.md +++ b/backlog/tasks/task-305 - orphan-files-iPod-detection-and-repair-coverage.md @@ -1,10 +1,10 @@ --- id: TASK-305 title: 'orphan-files (iPod): detection and repair coverage' -status: To Do +status: Done assignee: [] created_date: '2026-05-08 07:23' -updated_date: '2026-05-14 19:23' +updated_date: '2026-05-15 22:17' labels: - testing - doctor @@ -13,6 +13,9 @@ labels: milestone: m-19 dependencies: - TASK-322.05.01 +modified_files: + - packages/podkit-core/src/diagnostics/checks/orphans-matrix.test.ts + - packages/podkit-cli/src/commands/doctor-flag-matrix.test.ts priority: medium ordinal: 17000 --- @@ -44,24 +47,46 @@ Use the test harness landed in TASK-321 (Phase 1): ## Acceptance Criteria -- [ ] #1 No F* directories at all → status=skip or pass with details.orphanCount=0 -- [ ] #2 All files on disk are library-referenced → status=pass, details.orphanCount=0, details.wastedBytes=0 -- [ ] #3 Some files on disk not referenced by library → status=warn+repairable, details.orphanCount and wastedBytes reflect the orphan set, details.orphans lists each path+size -- [ ] #4 Library references files that do not exist on disk → status=pass for orphan-files check (this is a separate concern, not orphan detection) -- [ ] #5 Orphans spread across multiple F* directories → details.orphans contains all of them; CSV export contains every entry -- [ ] #6 CSV format: header is 'path,size'; each row is the orphan's path and byte size; paths containing commas/quotes are properly CSV-escaped -- [ ] #7 Verbose text output groups orphans by F* directory with count and total size -- [ ] #8 Verbose text output groups orphans by file extension with count and total size -- [ ] #9 Verbose text output lists the 10 largest orphan files by size, descending -- [ ] #10 Repair --repair orphan-files deletes all detected orphans; subsequent doctor reports pass -- [ ] #11 Repair --dry-run prints planned deletions without modifying the filesystem -- [ ] #12 Repair handles a mix of deletable and undeletable files (e.g. read-only): reports per-file errors in details, success=false when any fail -- [ ] #13 Repair preserves library-referenced files (asserted by re-running diff after repair) -- [ ] #14 Check is iPod-only (applicableTo: ['ipod']); mass-storage devices use orphan-files-mass-storage instead +- [x] #1 No F* directories at all → status=skip or pass with details.orphanCount=0 +- [x] #2 All files on disk are library-referenced → status=pass, details.orphanCount=0, details.wastedBytes=0 +- [x] #3 Some files on disk not referenced by library → status=warn+repairable, details.orphanCount and wastedBytes reflect the orphan set, details.orphans lists each path+size +- [x] #4 Library references files that do not exist on disk → status=pass for orphan-files check (this is a separate concern, not orphan detection) +- [x] #5 Orphans spread across multiple F* directories → details.orphans contains all of them; CSV export contains every entry +- [x] #6 CSV format: header is 'path,size'; each row is the orphan's path and byte size; paths containing commas/quotes are properly CSV-escaped +- [x] #7 Verbose text output groups orphans by F* directory with count and total size +- [x] #8 Verbose text output groups orphans by file extension with count and total size +- [x] #9 Verbose text output lists the 10 largest orphan files by size, descending +- [x] #10 Repair --repair orphan-files deletes all detected orphans; subsequent doctor reports pass +- [x] #11 Repair --dry-run prints planned deletions without modifying the filesystem +- [x] #12 Repair handles a mix of deletable and undeletable files (e.g. read-only): reports per-file errors in details, success=false when any fail +- [x] #13 Repair preserves library-referenced files (asserted by re-running diff after repair) +- [x] #14 Check is iPod-only (applicableTo: ['ipod']); mass-storage devices use orphan-files-mass-storage instead ## Implementation Notes **Dependency notes (added 2026-05-14):** Tier-3 assertions need TASK-322.05.01 (FunctionFS descriptor handshake) so the synthesised iPod persona enumerates and the device-scope orphan-files check has a target.

Dropped `repairOnly: true`; added `checkUdevRule()` with an injectable `readFile` seam. Returns pass / fail+repairable / warn+repairable / fail (EACCES) on Linux; skip on macOS+win32. Stale-diff text is intentionally terse — `"installed N bytes / M lines, expected N' / M'"` — for JSON consumers to spot drift without bloat. Repair-side path verifiably unchanged: all 15 pre-existing repair tests pass. TASK-301 ACs #11-#14 ticked, deferral notes replaced by a cross-reference to TASK-336. - **TASK-337** JSON shape symmetry: pass-path emits zero-valued details. orphans / orphans-mass-storage / artwork checks now emit `{ orphanCount: 0, ... }` / `{ corruptEntries: 0, ... }` on pass instead of an undefined `details` object. ~20 line Δ total. Text renderer already guards on status; no UX change. - **TASK-338** readiness stage details enrichment. usb stage pass-path now mirrors the unsupported-path shape `{ identifier, vendorId, productId, usbModel }`. Partition stage threads `PartitionLayout` from the platform probe through to details (`{ partitionCount, partitions: [{ index, filesystem, sizeBytes, identifier?, volumeUuid? }] }`). `PlatformDeviceInfo` widened additively with `filesystem?` + `partitionLayout?`. Platform asymmetries documented inline: Linux surfaces full kernel partition table, macOS surfaces user-visible only; filesystem strings differ ("vfat" vs "MS-DOS FAT32"). Net +3 tests in stage-matrix.test.ts. Quality gates: 57/57 turbo tasks green; 2643 @podkit/core pass; tsc + oxlint clean throughout. No commits made by individual workers; integrated state verified end-to-end before this commit. m-19 status: substantively COMPLETE. Only deferred work is the HITL hardware captures in TASK-324 (corrupt-db iPod 5G, populated echo-mini, Rockbox install) which require physical-device sessions.

Mirror the unsupported-path push: emit `{ identifier, vendorId, productId, usbModel }` (or whichever fields the unsupported-path already populates) on the pass path too. + +Anchors: +- `packages/podkit-core/src/device/readiness/index.ts` — locate the usb-stage push (search for `'usb'` push or `pushStage('usb', ...)`) +- `packages/podkit-core/src/device/readiness/index.ts:~218` — `createUsbOnlyReadinessResult`'s stage shape, the model to mirror + +## Gap 2: partition stage layout is invisible inside the cascade + +The partition stage is a passthrough inside `checkReadiness` because `findIpodDevices()` upstream filters to partitioned devices.

Top-level "part" entries (rare; some lsblk invocations) get a synthetic single-partition layout. Loop-device children are still skipped (virtual iPod server bookkeeping). +- macOS `listDevices()` calls a new `attachMacPartitionLayouts()` after building per-partition entries — groups by stripped whole-disk id (`disk5s2` → `disk5`), sorts by trailing slice number, and shares one layout payload across siblings. `getPlatformDeviceInfo()` now also captures `filesystem` from "File System Personality" / "Type (Bundle)". + +**Readiness pipeline (`readiness/index.ts`)** +- usb-stage pass-path push now mirrors the unsupported-path shape: `{ identifier, vendorId, productId, usbModel }` (omits each field when its source — `usbConnection` / `usbModel` — is absent, so legacy callers don't see `undefined` placeholders in JSON). +- partition-stage pass-path push routed through new `buildPartitionStageDetails()` helper.

That was correct but ugly — codegen step + base64 blobs + extra build script. Switched to Bun's native asset-import attributes: ```ts import sysInfoExtendedXml from './raw/sysinfo-extended.xml' with { type: 'text' }; import lsblkJson from './raw/lsblk.json' with { type: 'json' }; ``` Bun's bundler inlines the file content at build time; dev (TS source) runs see the raw bytes via its loader. The persona files now show their actual fixture filenames instead of base64 imports. Deleted: 16 `raw.generated.ts` files, `scripts/generate-raw-fixtures.ts`, `src/personas/lazy.ts`, the `generate:raw-fixtures` + `prebuild` package.json scripts. Added: `src/personas/text-imports.d.ts` (ambient declarations for the `with` import attributes). The no-fs-at-load smoke test still passes — 0 readFileSync calls at module-eval. Bundle output (`dist/index.js`, 260 KB) contains the fixture content inlined (verified by grep for fixture tokens). 16 persona files updated. **Doctor text summary: count warns alongside fails** TASK-308 locked in warn-counts-as-unhealthy → exit 2, but the human- text summary line ("N issues found." or "All checks passed.") was still counting `fail` only. Same fixture would emit `exit=2` paired with `"All checks passed."` when only warns existed — confusing. Fixed in `packages/podkit-cli/src/commands/doctor.ts:816-829`: the `issueCount` accumulation now includes `c.status === 'warn'` alongside `'fail'`. The readiness-stages filter likewise. The mass-storage and system-only paths were already correct. Updated `doctor-exit-code.test.ts` AC #9 assertion to match new behaviour (was: "stale comment removed; behavior unchanged"; now: "2 issues found" emitted when 1 fail + 1 warn). **Quality gates**: 57/57 turbo green; tsc + oxlint clean.

Refusing cleanly with a docs link is structurally cleaner than patching all three friction points and sharpens podkit's Linux story to "FAT32 iPods, supported well." macOS HFS+ is unchanged. Architecture - New `packages/podkit-core/src/device/filesystem-policy.ts` — single source of truth: `isFilesystemUnsupportedHere(filesystem, platform)`, `formatHfsplusOnLinuxRefusal()` (returns `string[]`). - Readiness pipeline gains an HFS+-on-Linux short-circuit that emits `level: 'unsupported'` with the canonical refusal text joined into `unsupportedReason` (main's existing string field — no discriminated union). No placeholder "Skipped" rows are pushed. - `device add`: refusal injected in BOTH iPod branches (explicit `--path` + scan-found) BEFORE any state mutation. Trailing-slash path normalisation on the `--path` lookup. - Docs: new `docs/devices/linux-filesystems.md`. AC #5 (real-hardware) deferred to TASK-319.

For HFS+ partitions on Linux that field is blank, so podkit cannot reliably re-find the same device after disconnecting and reconnecting it. +3. **udisksctl mounts HFS+ volumes at a generic path.** With no readable label, udisksctl falls back to `/media/$USER/disk` instead of the iPod's volume name. This makes disambiguation between multiple connected iPods difficult. + +Each of these has a partial workaround (turn off journaling, use a synthetic UUID, prompt for a label).

Three options, all outside podkit's scope to walk through end-to-end: + +- **iPod Reset Utility** (Apple) — official Windows/macOS tool. The simplest path if you have access to either OS. Boots the iPod into recovery mode and re-creates the FAT32 partition layout Apple ships from the factory. +- **Rockbox Utility** — if you intend to also install Rockbox firmware, the Rockbox utility can format the iPod's data partition as FAT32 as part of the install. See [Rockbox Compatibility](/devices/rockbox). +- **`mkfs.vfat` after manual partitioning** — for users comfortable with `parted` and `mkfs.vfat`, you can re-create the iPod's two-partition layout by hand on Linux. Apple's iPods ship with a small firmware partition (HFS+ on Mac iPods, FAT16 on Windows iPods) followed by the music partition. Recreating the firmware partition layout is fragile across iPod generations and is not recommended unless you've done it before. + +Once the iPod is reformatted as FAT32, run `podkit device add -d --path ` again on Linux and the refusal will not fire.

Wires it into `runDeviceScan`, replacing the ad-hoc disk-name correlation that produced a double-entry on Linux. Replaces the destructive `Needs partitioning — see: podkit device init` readiness copy with a docs link (the suggestion was doubly wrong: `device init` doesn't partition, and won't run on an unmounted device). Also extends `stripPartitionSuffix` to handle macOS BSD names and plumbs the sysfs USB fingerprint through `findIpodDevices` on Linux so block-side records carry the data reconciliation needs. AC #5 (real-hardware) deferred to TASK-319.

Previously the function short-circuited when a file was present, so the repair reported success without actually re-reading from firmware. - `--repair sysinfo-extended` (and any future repair that doesn't read the iTunesDB) no longer requires the DB to be openable. New `'database'` value on `RepairRequirement`; `runRepair()` only opens the DB when the repair declares it. Artwork + orphans repairs declare it; sysinfo repairs don't. - The readiness `SysInfoExtended:` status line distinguishes "not present" from "present but unparseable" so users can see when the file exists but won't parse (rather than thinking it's missing). Bug 3 (wires-crossed failure-explanation text) was already fixed on main by m-19's `buildCheckFailureDetails` switch; not duplicated here. AC #6 (real-hardware) deferred to TASK-319.

The linka EACCES repro now renders both transports' permission-denied paths instead of the previous one-line "Could not read device identity from USB" black box. Confirmed open question: the orchestrator's USB-then-SCSI plan already falls through to SCSI on any USB transport-layer throw (including EACCES); no plan-selection bug to fix. Added an orchestrator unit test to guard against any future regression that special-cases EACCES on USB and skips the planned SCSI fallback.

It left `/dev/bus/usb//` at the kernel default `0664 root:root`, so libusb-based firmware inquiry hit EACCES from SSH sessions, headless boxes, Docker containers, and CI — systemd-logind's `uaccess` ACL grants those nodes to active console seats only. Reproduced on linka 2026-05-09: even with the SCSI rule installed and james in plugdev, the USB-inquiry half of `doctor --repair sysinfo-extended` failed with no detail (orchestrator messaging fixed separately in TASK-317.14 / eed4126). Extends the rule with a second clause: SUBSYSTEM=="usb", ATTR{idVendor}=="05ac", MODE="0660", GROUP="plugdev", TAG+="uaccess" Attribute case matters: ATTR{} (singular) on the USB device's own attribute, ATTRS{} (plural) on the SCSI scope because scsi_generic has to walk up to the parent USB device. Renames the rule file `91-podkit-ipod-scsi.rules` → `91-podkit-ipod.rules` (it covers more than SCSI now). The repair installs the new filename and issues `sudo rm -f` for every legacy path in a new `LEGACY_TARGET_PATHS` constant, so users upgrading from an earlier podkit don't end up with two rule files loaded by udev. Cleanup runs only AFTER the new rule is in place — if `sudo cp` fails, the old rule stays untouched. In-source `UDEV_RULE_CONTENT` and the shipped `packages/podkit-cli/share/91-podkit-ipod.rules` are now byte-identical; a new test reads the share file and asserts string equality so they can't drift. Tests: - Rule-content shape tests assert both SCSI and USB clauses, the ATTR vs ATTRS distinction, exactly two `idVendor` matches. - New share-file equality test (covers AC #6 snapshot semantics). - `runUdevRuleInstall` tests for legacy cleanup: rm -f per legacy path, ordering after sudo cp, atomicity on cp failure, dry-run summary mentions the legacy paths. - 44/44 tests pass for the udev-rule module; 2701 unit tests + 69 integration tests pass for @podkit/core + podkit.

The identity cascade in `resolveIpodModel` silently picks ModelNumStr today, so podkit would misidentify TERAPOD (iPod 5G with iFlash mod) as video_5g when the firmware-stamped serial 9C642MEFV9M → V9M → A446 puts it on video_5_5g. The existing `sysinfo-consistency` check compares ModelNumStr vs USB (both 5G — agreed) so no signal fires; this new check compares classic ModelNumStr vs the SysInfoExtended-derived serial suffix. The check is `warn` (not `fail`): the device still works, it's just misidentified. Skips silently when the on-disk ModelNumStr is the only identity available (mini 2G S4G regression target) or when firmware truth is unobtainable. Repair `--repair sysinfo-modelnum-mismatch` rewrites the on-disk ModelNumStr line in place from the firmware-derived variant, after backing up the original to SysInfo.podkit-backup. Other lines preserved verbatim to protect uncatalogued keys. Firmware-truth cascade: SysInfoExtended.SerialNumber first (richest; firmware-stamped; gives variant via suffix lookup), then liveIdentity.model (USB-derived; generation only). USB-only truth can detect the mismatch but the repair refuses to write (no model number to project back). Injection seams (SysInfoFsReader + SieReader) keep tests off the real filesystem without `mock.module('@podkit/ipod-firmware', ...)`, which would leak across Bun test files and break unrelated readiness suites. Hardware verification of the TERAPOD before/after flow and the 5-device regression sweep deferred to TASK-319 per the task spec.

No command leaks `libgpod` into user-facing copy. Behaviour changes: - `device add` on an unsupported device now warns and offers "Add anyway? [y/N]" (--yes flips default). Confirmed devices land in config with `unsupported: true`. - `device add` consults USB classification when disk scan finds nothing so iOS devices surface the canonical unsupported message instead of the generic "No iPod devices found". - `device scan` shows the resolved model label (or `iOS device` for unknown iOS-range PIDs) instead of `Unknown iPod`. - `sync --dry-run` refuses cleanly on unsupported generations before opening anything — no track plan generated. - `sync`'s `open-device.ts` composes the full identity cascade (SIE + USB + libgpod fallback) so the libgpod-only "Could not identify" warning is gone for SIE-present devices. - `device info` renders the cascade `displayName`. - `doctor` suppresses mutating repair suggestions on unsupported readiness AND refuses explicit `--repair` invocations against unsupported devices (guards against corruption on hashAB nanos). New `DeviceConfig.unsupported?: boolean` field records the user's warn-allow confirmation. TOML round-trips through loader + writer. AC #11 (hardware) deferred to TASK-319.

After: a single unified renderer with the same section ordering on every device type. Empty sections are omitted, so an Echo Mini with no readiness-category checks just shows System then Database Health. Architecture: kept it additive (option B from the spec). New `category?: 'readiness' | 'database'` field on `DiagnosticCheck` discriminates device-scope checks into the right subsection without breaking the existing `scope` union (which would have touched every check). Forwarded through `DiagnosticReport.checks` and the JSON `DoctorCheckOutput` envelope so consumers can re-render the same grouping. Renderer: extracted `printGroupedChecks(out, checks)` in doctor.ts that the mass-storage path now calls directly. iPod path keeps its readiness-stage pipeline for the Device Readiness section but uses the same scope/category filters for System + Database Health, and skips device+readiness checks in Database Health to avoid double rendering once a mass-storage readiness check is added. iPod-only system check: `inquiry-methods` is now `applicableTo: ['ipod']`. The check probes SCSI/USB transports specific to iPod firmware inquiry, so surfacing it on an Echo Mini under "System" misleads users into thinking iPodDriver.kext matters for their device. The existing applicableTo filter in the registry already handles the routing. Per-check categorisation (every device-scope check tagged `category: 'database'`): - artwork-rebuild, artwork-reset - orphan-files, orphan-files-mass-storage - sysinfo-extended, sysinfo-consistency, sysinfo-modelnum-mismatch Tests: - scope-category-matrix.test.ts: per-check assertion that scope + category + applicableTo are declared correctly. Single expectation table is the source of truth for which section each check lands in; new checks add a row here. - doctor-grouped-render.test.ts: drives `printGroupedChecks` with synthetic check fixtures to pin section ordering, empty-section omission, repairOnly skipping, the legacy-no-category fallback, and the Echo Mini scenario. - inquiry-methods.test.ts: pinned applicableTo to ['ipod']. Quality gates: lint 0 errors, build OK, 2762 unit tests pass, 69 integration tests pass. AC #1-#8 covered; AC #9 (real-hardware verification) deferred to TASK-319 per task spec.

That was the deferred Approach B — additive and unenforced. Every new device-scope check had to remember to tag itself, and a forgotten tag silently rendered in the wrong section. This commit lands Approach A: a single required scope discriminator on every check, with no defaulting and no fallback. `DiagnosticCheck.scope` is now `'system' | 'device-readiness' | 'database-health'` and is no longer optional — the compiler rejects any check that omits it. The renderer branches on `scope` directly with three buckets and prints sections in fixed order (System → Device Readiness → Database Health), omitting empty ones. The user-facing CLI surface is unchanged. `--scope system | device | all` still accepts the same three values; `device` simply expands internally to the two device-side scopes (`device-readiness` + `database-health`) before being forwarded to `core.runDiagnostics({ scopes })`. `--no-system` keeps its existing meaning of "skip system checks; run everything else". JSON shape change: `DoctorCheckOutput` and `DiagnosticReport.checks[]` no longer carry a `category` field, and the `scope` values are the new 3-way union. The additive field only landed in TASK-317.08 (commit 78b0c71), so there are no external consumers depending on the prior shape — no migration.

The JSON envelope (`DeviceScanDeviceEntry`) is user-facing API — versioned migration via changeset minor bump. Coordinate with TASK-317.07 (mass-storage preset display metadata) which may also touch the JSON envelope. + +## 2. Docs site doesn't have new pages live + +**Problem**: TASK-317.12 added `docs/devices/linux-filesystems.md` and TASK-317.11 added `docs/devices/troubleshooting.md`. Both are referenced from user-facing CLI messages via the central `DOCS_URLS` constant pointing at `jvgomg.github.io/podkit`. The docs site deploys from `docs-live` branch (per `agents/releases.md`), and the next release sync hasn't happened yet — every CLI message pointing at the new URLs currently returns 404. + +**Proposal**: Cherry-pick the two new docs pages from `main` onto `docs-live` ahead of the next release. Add a step to the release checklist (or automation) that detects new files under `docs/` since the last sync and queues them for `docs-live` integration. Or just deploy `docs-live` more aggressively for docs-only changes. + +## 3. Test style + mocking patterns vary across workers + +**Problem**: Workers landed during the m-18 hygiene cluster used different test idioms: +- Some tests assert against full snapshot output (`expect(out.text()).toMatchSnapshot()`). +- Others use explicit field-by-field assertions (`expect(result.unsupported?.kind).toBe('ios-device')`). +- Some use `mock.module('@podkit/ipod-firmware', ...)` (which TASK-317.04 noted "leaks across Bun test files and breaks unrelated readiness tests"). +- Others use injected fakes via optional constructor parameters (`{ SysInfoFsReader, SieReader }`). + +**Proposal**: Write `agents/testing.md` (already referenced in `AGENTS.md` but may not exist yet — verify) with concrete guidance: +- Prefer dependency injection over `mock.module()`. +- Snapshot tests for stable user-facing text; explicit assertions for structured data. +- One canonical fake builder per persona (lives in `@podkit/device-testing`). +- Run-time test mocks via `bun:test`'s `mock()` only at function-call boundary, never via `mock.module()`. + +## 4. Three stale worktrees on disk + +**Problem**: Three orphan worktree directories under `.claude/worktrees/` carry uncommitted state from the wave-1 worker runs (HFS+ refusal, reconcile, doctor repair). Their work was re-integrated directly onto `main`; the worktree state is dead weight. + +**Proposal**: One-liner cleanup: +```bash +for w in agent-a9bfc1d0cce752a3f agent-a6d99f9921f986071 agent-ada048c181d1f510d; do + git worktree remove --force ".claude/worktrees/$w" + git branch -D "worktree-$w" 2>/dev/null || true +done +``` + +(Verify each branch name first — `git worktree list` shows the canonical names.) Could be added to a periodic "session cleanup" script. + +## 5. DOCS_URLS trailing slash inconsistency + +**Problem**: The central `DOCS_URLS` constant (commit `b572b9e`) emits URLs without trailing slashes. But some Starlight pages serve from URLs that DO have trailing slashes (`/troubleshooting/macos-mounting/` etc.). Worker had to add trailing slashes at the call site (`${DOCS_URLS.macosMounting}/`) for two tips. Inconsistent. + +**Proposal**: Either (a) include trailing slashes uniformly in `DOCS_URLS` (matches Starlight `trailingSlash: 'always'` default — depending on `astro.config.mjs` config), or (b) drop them everywhere and rely on Starlight's redirect. Pick one and pin it via a unit test that all `DOCS_URLS` entries end with or don't end with `/`. + +## 6. Worktree-then-integrate workflow waste + +**Problem**: The wave-1 work used three isolated worker worktrees, then `main` moved 3 m-19 commits, then every worker's output had to be recomposed against new APIs. Token-spend roughly 2–3× vs in-place work. + +**Proposal**: Document in `agents/team-lead.md` (or wherever the orchestration guidance lives) that worktrees are appropriate for long-running parallel tracks but NOT for sequential single-feature work where main is actively moving. The right cadence: pull `origin/main` before spawning each worker; if main has moved meaningfully, abandon worktree isolation and work in main directly. + +## 7. Backlog state churn during sessions + +**Problem**: Many incremental `task_edit` calls during the m-18 session — each commit was preceded by one or two task-status updates. The MCP backlog edits commit as separate small commits that noise up the log. + +**Proposal**: Batch task updates to the end of the session as a single "backlog: session updates" commit. Alternative: a single "session journal" task captures running decisions; per-task status updates happen only at task completion. + +## 8. Pre-existing lint warnings on unrelated files + +**Problem**: `bun run lint` reports 4 warnings on files untouched by this session (`packages/podkit-core/src/device/ipod-adapter.ts` `no-console`; `mass-storage-tag-writer.ts` `no-new-array`; `device-testing/.../no-fs-at-load.probe.mjs`). Pre-existing but cluttering output. + +**Proposal**: Either clear them (likely small fixes) or add eslint-disable comments with explanations. Or upgrade the lint config to surface them differently so they don't drown out new findings. + +## 9. CLI command files growing large + +**Problem**: `packages/podkit-cli/src/commands/doctor.ts` is now ~1290 lines. `device/add.ts` is similarly large after the wave-1 work. They mix command-line parsing, business logic, rendering, and JSON output. + +**Proposal**: Split per the pattern already in use (`device-scan-render.ts` is a separate file from `device/scan.ts`). For doctor specifically: extract the readiness/scope-resolution helpers into a sibling, the failure-explanation router into another, the rendering helpers into a third.

Add a test-only escape hatch: - `synthesizeTestVolumeUuid(path)` in `device/add.ts` returns a deterministic `test-` UUID when `PODKIT_TEST_SYNTHETIC_VOLUME_UUID=1` is set in the env; both `--path` and scan-found refusal sites consult it before throwing. - The e2e CLI runner (`packages/e2e-tests/src/helpers/cli-runner.ts`) sets the env var unconditionally so every dummy-target test gets the hatch. Real users never set this variable; production refusal is unchanged. All 27 e2e workflows now pass against the dummy target.

[y/N]". Writing SysInfoExtended to a device we've just recorded as `unsupported = { kind, confirmedAt }` is wasted work — and fails outright against tmpdir-backed test paths (`EACCES: mkdir /Volumes/TOUCH`) since the offered firmware-inquiry write is the only step in the flow that actually requires a writable filesystem. Gate `offerFirmwareInquiry` on `!recordUnsupported` in both the explicit-`--path` branch and the scan-found branch. The skipped write matches the no-database-init behaviour already in place for unsupported devices. Fixes the failing unit test `runDeviceAdd: nano 2G slick-flow > persists unsupported rich shape when the user accepts the warn-allow prompt (TASK-317.03)`.

Three sibling shapes still carried the legacy bare-string `notSupportedReason` field, forcing every consumer to re-derive the `kind` discriminator and re-attach the docs URL: - `IpodIdentity` (@podkit/device-types) - `IpodClassification` (@podkit/devices-ipod) - `DeviceScanDeviceEntry` (podkit-cli JSON envelope) All three now expose `unsupportedReason?: ReadinessUnsupportedReason`. The shared producer lives in `@podkit/devices-ipod` as `lookupUnsupportedReadinessReason(productId)`, which combines the existing PID-table lookup + iOS-range fallback and picks the `kind` discriminator (`ios-device` for PIDs in 0x1290–0x12af, `unsupported-device` otherwise). The CLI's local `makeIpodUnsupportedReason` helper goes away. The JSON envelope rename is a user-facing breaking change covered by the `.changeset/device-scan-unsupported-reason.md` minor bump: consumers reading `device.notSupportedReason` now read `device.unsupportedReason.headline` for the same single-line message.

A `mock.module('@podkit/ipod-firmware', …)` in one test file was observed leaking into unrelated readiness tests during the m-18 hygiene cluster. Existing CLI runners already use dependency-injected `Deps` shapes (`agents/testing.md` §"The deps seam, in detail"); this commit extends the same pattern down into the four library call sites that still used `mock.module()`: - `ipodProvider` → `createIpodProvider({ inquireFirmware })` factory. `ipodProvider` keeps its default-wired export; tests construct their own provider with a stubbed firmware-inquiry function. - `runSysInfoExtendedRepair` → optional `SysInfoExtendedRepairDeps` parameter for `ensureSysInfoExtended`, `resolveUsbDeviceFromPath`, and `hasCompleteUsbFingerprint`. Both `sysinfo-extended.test.ts` and `sysinfo-consistency-repair.test.ts` now invoke the runner directly with injected fakes; the production check objects remain unchanged. - `VideoHandler` → optional second constructor parameter `VideoHandlerDeps` for `transcodeVideo`, `probeVideo`, `executor-fs` (mkdir/stat/rm), and the iPod `video.ts` helpers. - `DirectoryAdapter` → optional second constructor parameter `DirectoryAdapterDeps` for `glob` and `music-metadata`'s `parseFile`. The class's internal `parseFile` private method had to rename out of the way (now `parseAudioFile`) — the collision was hiding silent recursion until the test confirmed the stub was wired. No production callers change behaviour: every dep defaults to the real import. Test files no longer touch `mock.module()` at all. --- packages/devices-ipod/src/index.ts | 2 +- packages/devices-ipod/src/provider.test.ts | 48 +++--- packages/devices-ipod/src/provider.ts | 150 ++++++++++------- .../src/adapters/directory.test.ts | 128 +++++++------- .../podkit-core/src/adapters/directory.ts | 25 ++- .../checks/sysinfo-consistency-repair.test.ts | 156 +++++++----------- .../checks/sysinfo-extended.test.ts | 143 ++++++++-------- .../diagnostics/checks/sysinfo-extended.ts | 28 +++- .../src/sync/video/handler-execute.test.ts | 127 +++++++------- .../podkit-core/src/sync/video/handler.ts | 75 +++++++-- 10 files changed, 478 insertions(+), 404 deletions(-) diff --git a/packages/devices-ipod/src/index.ts b/packages/devices-ipod/src/index.ts index 8abf540f..399c36bb 100644 --- a/packages/devices-ipod/src/index.ts +++ b/packages/devices-ipod/src/index.ts @@ -86,7 +86,7 @@ export { // ── Provider ────────────────────────────────────────────────────────────────── -export { ipodProvider } from './provider.js';

This is the first step in a longer migration: the persona registry is already the single source of truth for "what USB descriptor does this device present?", but unit tests up the stack have been re-encoding the same descriptors inline. Going through the builder keeps the fixtures in lockstep with the registry — if a persona is renamed, recaptured, or its USB IDs change, the unit tests pick up the change without a separate edit. Three personas now feed the renderer test: - `ipodVideo5gIflash1tb` (supported iPod, PID 0x1209) - `ipodTouch5gUnsupported` (unsupported iOS device, PID 0x12aa) - `echoMini` (mass-storage DAP, PID 0x3203) Adds `@podkit/device-testing` as a devDependency of `podkit-cli` so the persona registry is available to CLI unit tests. Re-exports the individual personas from the package's public entry so callers don't need to reach through the `personas` map by id. Subsequent migrations of `device-scan.unit.test.ts` and the rest of the ad-hoc inline fixtures are deferred — the builder is in place and the migration pattern is established. --- bun.lock | 1 + packages/device-testing/src/index.ts | 22 +++++++- .../device-testing/src/personas/builders.ts | 56 +++++++++++++++++++ packages/podkit-cli/package.json | 1 + .../commands/device-scan-render.unit.test.ts | 30 +++++----- 5 files changed, 95 insertions(+), 15 deletions(-) create mode 100644 packages/device-testing/src/personas/builders.ts diff --git a/bun.lock b/bun.lock index 7c32adc3..ed2775a7 100644 --- a/bun.lock +++ b/bun.lock @@ -191,6 +191,7 @@ "usb": "^2.17.0", }, "devDependencies": { + "@podkit/device-testing": "workspace:*", "@podkit/gpod-testing": "workspace:*", "@types/bun": "latest", }, diff --git a/packages/device-testing/src/index.ts b/packages/device-testing/src/index.ts index 24c73d07..eed8be5d 100644 --- a/packages/device-testing/src/index.ts +++ b/packages/device-testing/src/index.ts @@ -23,7 +23,27 @@ import { registerRunner } from './runners/registry.js'; // Personas export type { DevicePersona, DoctorOutput } from './personas/types.js'; -export { personas } from './personas/index.js'; +export { + personas, + ipodMini2gPink, + ipodNano3gBlack, + ipodNano4gBlack, + ipodNano2gGreen, + ipodNano7gBlue, + ipodNano7gSpaceGray, + ipodVideo5gIflash1tb, + ipodTouch5gUnsupported, + echoMini, + sonyNwzE384, + sonyNwA1000, + sonyNwA3000, + sonyNwA1200, + sonyNwHd5, + ipodShuffleNotSupported, + nonIpodUsbDisk, + malformedSysinfo, +} from './personas/index.js'; +export { buildEnumeratedUsbDevice } from './personas/builders.js'; // Persona sidecar (JSON serialisation consumed by the FunctionFS daemon) export type { diff --git a/packages/device-testing/src/personas/builders.ts b/packages/device-testing/src/personas/builders.ts new file mode 100644 index 00000000..75d67308 --- /dev/null +++ b/packages/device-testing/src/personas/builders.ts @@ -0,0 +1,56 @@ +/** + * Canonical builders that derive runtime fixture shapes from a + * {@link DevicePersona}. + * + * Tests in higher layers (podkit-cli, e2e) frequently need an + * `EnumeratedUsbDevice` matching a known persona — for example, to feed + * `classifyAsIpod` and walk the rendering pipeline.

The flat-only schema could describe "a device exists" but could not drive a FunctionFS daemon to synthesise a believable gadget — Mass Storage class `0x08` lives on the **interface descriptor**, not the device descriptor, and every iPod and every Sony Walkman reports `deviceClass = 0` because they are composite devices. + +2. **`partitionLayout.luns[]`.** v1 flattened all partitions into a single `partitions[]` array. v2 reshapes to `{ luns: Array<{ lun, partitions[] }> }`. Echo Mini is the canonical multi-LUN device (internal FAT32 firmware on LUN 0 + SD-card ExFAT on LUN 1); v1 modelled both LUNs as a single flat partition array with an apologetic comment. Future multi-LUN devices hit the same issue without this reshape. + +3. **`deviceSerial: string | null`.** Sony NW-HD5 (and the older NW-A HDD Walkmans) advertise `iSerialNumber = 0` in the device descriptor — no serial-descriptor index assigned. v1 used `''` as a workaround; v2 makes it `null` so the absence is semantically explicit, eliminating the `if (persona.deviceSerial) {...}` empty-string-as-falsy footgun. + +**Daemon compatibility note.** The sidecar wire shape (`packages/device-testing/src/personas/sidecar.ts`) was deliberately **not** changed. The dummy-hcd daemon only needs vendor/product IDs, an optional serial string, and class/subclass/protocol fields to bind the configfs gadget — the richer hierarchy stays host-side. The sidecar builder (`sidecar-build.ts`) was updated to project `deviceSerial: null` to an omitted `serial` field (rather than serialising `null`), so the daemon's existing optional-string fallback (`'000000000001'`) continues to work. + +**Migration scope.** All 17 personas migrated mechanically: `schemaVersion: 1 → 2`, `partitions[...] → luns: [{ lun: 0, partitions: [...] }]`, `usbDescriptor` extended with synthesised hierarchy fields drawn from raw probe data (`raw/sysfs-usb.txt`, `raw/ioreg.txt`, `raw/udev.txt`) where available. Personas without raw probe data (mini 2G, nano 2G, video 5G, touch 5G, shuffle, malformed-sysinfo, synthetic state-variants) inherit hierarchy values from the matching family pattern and flag a follow-up Linux capture in `provenance.md`. Sony NW-A1000, NW-A1200, NW-A3000, NW-HD5 migrate `deviceSerial: ''` → `null` (all four advertise `iSerialNumber = 0`); other personas keep their non-empty serials. + ### `SystemState` schema A `SystemState` describes a particular host-environment configuration that affects doctor system-scope checks.

The + `runDoctorAction` mass-storage branch (doctor.ts:404-413) checks + `applicableTo.includes('mass-storage')` for repairs run against + mass-storage devices. The iPod branch has NO matching check — a user + running `podkit doctor --repair orphan-files-mass-storage -d ` + gets dropped through to `runRepair`, which opens the iPod database + and runs the mass-storage-orphan check semantics against an iPod + filesystem. Real-world impact is low (the check semantics don't + match an iPod layout, so it will either do nothing or fail safely), + but the UX is misleading. Fix would be: add a symmetric gate to the + iPod branch around doctor.ts:425. + +2. **`-d ` does not auto-detect mass-storage device type** + (AC #11). When the user points `-d` at a FAT32 mountpoint that + matches no configured device, the doctor falls through to the iPod + default flow. A pre-flight check for the absence of `iPod_Control/` + + presence of `Music/` (or a similar mass-storage marker) could + resolve the device type from the path alone.
