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 (`test-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 image is formatted and left empty. Used by `echo-mini` (sync-target detection on an empty device). +- **Seeded backing image** — add `synthesis.initialContent: Array<{path, sourceFixture}>`. `path` is the in-image absolute path (no leading `/`, ASCII-safe charset only). `sourceFixture` is the persona-relative host path (e.g. `./raw/iTunesDB`). The runner `limactl copy`s each fixture into a per-persona scratch dir, then `mcopy`s into the post-`mkfs.vfat` image with `SOURCE_DATE_EPOCH` fixed so the seeded bytes don't perturb determinism.

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.

If we want this persona to round-trip clean, the fix is on the live USB → model side, either by promoting 0x1209 to a "video_5g_or_5_5g" sentinel or by re-using ModelNumStr/FamilyID hints from the on-disk file to disambiguate.

Surfaced for visibility; not refactored here. +- `SystemState` fixtures in `@podkit/device-testing` carry `expectedExitCode: 1` for non-healthy states, which doesn't match the actual exit 2 the doctor emits. TASK-324 owns the fixture sweep; flagged for that ticket. +- The persona registry can't yet be imported here — the bundled `@podkit/device-testing/dist/index.js` eagerly evaluates every persona's `readFileSync` on raw XML/plist files that the bundler does not copy. TASK-324 will fix that; the test file is structured for a clean migration when it does. + +**No doctor-logic bugs found.** The exit-code derivation matches the documented decision across every matrix cell tested. + +**Tier-3 deferral:** AC coverage of `--scope system` against a live VM (TASK-322.06 baseline) is deferred to the next Tier-3 sweep.

Before: `issueCount` only accumulated `c.status === 'fail'`, so a warn-only failure produced exit 2 but printed "All checks passed." After: `issueCount` accumulates `c.status === 'fail' || c.status === 'warn'`, so the same fixture prints "1 issue found." (or "N issues found."). AC #9 test assertion updated from a "contains both check names" check to also assert `'2 issues found.'` for the 1-fail + 1-warn fixture. 30 tests, all green. Files touched: `packages/podkit-cli/src/commands/doctor.ts`, `packages/podkit-cli/src/commands/doctor-exit-code.test.ts`. + +**Persona registry packaging gap — resolved (m-19 polish, follow-up to this task).** The line in the implementation notes above ("the bundled `@podkit/device-testing/dist/index.js` eagerly evaluates every persona's `readFileSync` on raw XML/plist files that the bundler does not copy") no longer applies. The fix: each persona's raw fixtures are now inlined as base64-encoded string literals in a sibling `raw.generated.ts` module produced by `packages/device-testing/scripts/generate-raw-fixtures.ts` (wired as the package's `prebuild` step), and persona modules wrap raw-fixture fields in cached getters (`src/personas/lazy.ts`). A subprocess smoke test in `src/personas/no-fs-at-load.test.ts` pins zero `fs.readFileSync` calls at module-eval. External consumers can now import `personas` from `@podkit/device-testing` without filesystem fragility. Pattern documented in `agents/device-testing.md` §"Lazy raw-fixture pattern". + +**2026-05-16 — Persona registry packaging: codegen replaced with Bun import attributes.** The base64 codegen path documented in the previous note has been removed. Raw fixtures are now imported directly via `with { type: 'text' }` (XML/plist) and `with { type: 'json' }` (JSON) — Bun's bundler inlines the file contents as string/object literals at build time, and at dev time Bun's loader resolves them without `fs.readFileSync`. Files deleted: `packages/device-testing/scripts/generate-raw-fixtures.ts`, `packages/device-testing/src/personas/lazy.ts`, all 16 `src/personas/*/raw.generated.ts` files, plus the `generate:raw-fixtures` + `prebuild` scripts in `package.json`. Ambient declarations for `*.xml` / `*.plist` / `*.txt` live in `packages/device-testing/src/personas/text-imports.d.ts` (JSON is covered by `resolveJsonModule`). The `no-fs-at-load.test.ts` smoke test contract is unchanged and still passes (zero `fs.readFileSync` calls during persona registry import).

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).
