Lands every subtask of TASK-321 except TASK-321.02 (hardware persona captures, deferred to HITL). New package @podkit/device-testing - DevicePersona + SystemState schemas (verbatim per ADR-017) - TestRuntime interface + local-linux runner with auto-registration - Subprocess capture/replay framework (PODKIT_SNAPSHOT_CAPTURE / PODKIT_SNAPSHOT_REPLAY) with 21 framework tests - SystemState registry seeded with 6 starter states (healthy, no-ffmpeg, no-libgpod, no-udev, no-sg-perms, corrupt-configfs) plus a golden-file fixture for the healthy state Cross-package refactor (cycle-free) - SubprocessRunner interface in @podkit/device-types so production packages can depend on the type without importing the test harness - defaultSubprocessRunner in @podkit/core; device-testing re-exports it to keep behaviour in lockstep - podkit-core callsites threaded through the runner: usb-enumeration, usb-path-resolution, device/platforms/{macos,linux}, diagnostics video-encoder check, transcode/ffmpeg.exec() - Streaming spawns (FFmpegTranscoder.transcode, video probe/transcode, music pipeline transcode, artwork resize) left on existing _spawnFn DI; documented in subprocess.md Per-OS test tagging convention - *.darwin.test.ts / *.linux.test.ts via describe.skipIf - Canary tests prove the convention works on both hosts - Documented in agents/testing.md Linux native build pipeline - tools/prebuild/build-linux-glibc.sh: single shared script invoked by .github/workflows/prebuild.yml glibc matrix AND tools/device- testing/lima/builder.yaml (Debian 12.10 pinned) - tools/device-testing/lima/abi-verify.yaml: stock-Debian VM used for the ldd static-link spike - turbo tasks @podkit/device-testing#build:linux-prebuild and build:linux-binary with full cache inputs - mise tasks device-testing:build-linux* - ABI spike (TASK-321.07 AC #12): ran end-to-end on aarch64 Apple Silicon Lima; ldd reported only linux-vdso, libc, libpthread, libdl, libm, ld-linux-aarch64 -- zero libgpod/libglib/libgdk_pixbuf /libplist references. x64 verification deferred to first CI run on ubuntu-24.04. Documentation - New agents/device-testing.md: canonical reference for the harness - agents/testing.md gained a Three-Tier Test Stack section - All 11 tasks TASK-301..TASK-311 swept with harness-integration notes so implementers land on the new stack Cross-references - adr/adr-016-linux-vm-test-harness.md (Accepted) - adr/adr-017-device-persona-fixtures.md (Accepted) - agents/device-testing.md - packages/device-testing/README.md - tools/device-testing/lima/README.md Deferred / follow-ups (not blocking) - TASK-321.02 hardware persona captures (HITL, awaiting devices)

They are byte-equivalent and trivially small (one `execFile` wrapper). Sharing would either force production to depend on `@podkit/device-testing` (rejected by task constraint) or move the implementation into `@podkit/device-types` (which would no longer be a types-only package). The duplication is acceptable given the size and isolation. + +### Streaming spawns left alone +The task description says "every callsite" of ffmpeg/ffprobe, but the streaming `FFmpegTranscoder.transcode()`, `video/transcode.ts:transcodeVideo`, `video/probe.ts:probeVideo`, `video/metadata-embedded.ts`, `sync/music/pipeline.ts` ffmpeg spawn, and `artwork/resize.ts` ffmpeg spawn all consume stdout progress in real time. `SubprocessRunner.run` is a request/response shape and cannot preserve that semantic. These callsites already have their own `_spawnFn` DI seam for test injection. Switching them would (a) require widening `SubprocessRunner` or (b) drop progress reporting. I left them on `spawn` and documented this in `subprocess.md`. Hooking them into the snapshot framework can ship as its own task with a wider `SubprocessRunner` (e.g. `runStreaming(...)` returning an event emitter). + +### Diagnostics `video-encoder` check uses default runner directly +The check signature `check(ctx: DiagnosticContext)` doesn't carry a subprocess; plumbing one through `DiagnosticContext` would be a much wider refactor. I routed `ffmpegEncoders()` through the abstraction but pass `defaultSubprocessRunner` from the check itself. Future task can widen `DiagnosticContext`. + +### Linux device manager's `mount`/`umount` semantics preserved +Original `execCommand` returned `code: 1` on transport failure (binary not found, etc.) rather than throwing. My replacement preserves that contract exactly by try/catch around `subprocess.run` and collapsing rejections into `code: 1` — the surrounding code in those files inspects `code` and acts accordingly, so the behaviour is identical. + +### FFmpegTranscoder.exec()'s signal abort dropped +`FFmpegTranscoder.exec()` previously installed an `AbortSignal` handler in its private exec method, but no caller ever passed a signal (verified via grep). The new version drops the dead signal plumbing; `transcode()`'s streaming spawn still installs its own signal handler. + +### Env merging +`opts.env` is merged onto `process.env` by `defaultSubprocessRunner` (same semantics as the previous ad-hoc `execFile` calls). The hash function treats `env: undefined` and `env: null` as equivalent so fixtures captured without explicit env still replay against calls that pass `env: undefined`. + +### Fixture storage convention +Capture/replay runners take a directory string and don't know about persona layout. The convention is (per task spec): `packages/device-testing/src/personas//subprocess-fixtures/` for per-persona, `packages/device-testing/fixtures/shared/` for environment-independent.

The builder VM yaml installs a newer `meson` via pip3 because Debian 12.10's apt meson (1.0.1) is too old for glib 2.82.4 (≥1.2.0 required). This won't surface in CI because `prebuild.yml` runs on `ubuntu-24.04` which has new meson natively. If you bump the Debian point release and apt meson is ≥1.2.0, you can drop the pip install. +2. AC #6 (musl regression check): only the glibc job changed. Visually inspect `git diff .github/workflows/prebuild.yml` — every change is gated on `matrix.platform == 'linux'` or `matrix.platform == 'darwin'`, never inside the `prebuild-musl-x64` / `prebuild-musl-arm64` jobs (those are below line ~145 and untouched). +3. `build:linux-binary` renames the produced binary to `podkit-linux-${arch}` so subsequent macOS `bun run compile` doesn't clobber it via the same `bin/podkit` target. +4. The host script `build-linux-binary.sh` symlinks `node_modules` to `/tmp/podkit-builder-nm` inside the VM to avoid Bun rewriting the macOS-resolved native modules on the shared mount. This pattern mirrors `mise run vipod:install`. +5. A `--dry-run` of either turbo task is enough to verify discoverability; the actual run requires Lima to be installed on the host (`brew install lima`). +6. `build-platform.yml` has no glibc Linux path today (only Alpine/musl). If a glibc target is added there in future, route it through `build-linux-glibc.sh` too. + +**Quality gates run:** +- `bun -c "bash -n"` on all new shell scripts — pass +- `bash tools/prebuild/build-linux-glibc.sh` on macOS host — refuses correctly with helpful error +- `bunx turbo run @podkit/device-testing#build:linux-prebuild --dry-run` — discoverable, hash stable, inputs correct +- `bunx turbo run @podkit/device-testing#build:linux-binary --dry-run` — discoverable, depends on prebuild + ^build +- `yamllint` (with line-length/doc-start disabled, comments min-spaces-from-content=1) on builder.yaml + abi-verify.yaml + prebuild.yml — clean +- `bunx prettier --check` on all new/modified non-toml files — clean +- `bunx oxlint packages/device-testing/` — 0 warnings / 0 errors +- `bunx oxlint .` — 1 pre-existing warning, 0 errors (unrelated `no-new-array` in mass-storage-tag-writer.ts) +- End-to-end build inside Lima — pass (binary works, ldd clean) +- ABI spike in stock-Debian VM — pass (ldd as captured above) + +Pre-existing `bun run typecheck` / `bun run build` failures in `packages/podkit-core/src/device/platforms/macos.ts` (TS2554 "Expected 3 arguments, but got 2") are from a WIP refactor on this branch (`feat/m-19-phase-1`) introducing a `SubprocessRunner` parameter — unrelated to this task and not introduced by these changes. + + +## Final Summary + + +Reviewer follow-ups folded in by team-lead before next phase: (1) fixed builder.yaml manual-usage example — Lima mounts $HOME, so the example should use `--workdir "$(pwd)"` from the repo root, not a fictional `/podkit` path; mount-section comment also corrected to describe the actual semantics. (2) Removed false claim in `build-linux-glibc.sh` header that `build-platform.yml` is a caller — only `prebuild.yml` + `builder.yaml` invoke it. (3) Broadened the in-script `ldd` grep pattern to match the binary-level verify (adds libgobject, libgio, libgmodule, libffi, libxml2, libsqlite, libpcre2, libpng, libjpeg, libtiff to the forbidden list) so addon-level static-link regressions can't sneak through. + +Known gap (not blocking): the local ABI spike ran on aarch64 (Apple Silicon Lima default). x64 verification deferred to first CI run on `ubuntu-24.04` x64 runners — this is the same pipeline that ships glibc binaries today, so the static-link contract will be enforced there on the first push of this branch. + diff --git a/backlog/tasks/task-321.08 - Agent-directives-TASK-301..311-harness-sweep.md b/backlog/tasks/task-321.08 - Agent-directives-TASK-301..311-harness-sweep.md index 3ca6ab84..87095564 100644 --- a/backlog/tasks/task-321.08 - Agent-directives-TASK-301..311-harness-sweep.md +++ b/backlog/tasks/task-321.08 - Agent-directives-TASK-301..311-harness-sweep.md @@ -1,9 +1,10 @@ --- id: TASK-321.08 title: Agent directives + TASK-301..311 harness sweep -status: To Do +status: Done assignee: [] created_date: '2026-05-12 11:55' +updated_date: '2026-05-13 18:06' labels: - testing - vm-coverage @@ -53,8 +54,29 @@ For each of TASK-301 through TASK-311 (11 tasks), append a short note to the exi ## Acceptance Criteria -- [ ] #1 agents/testing.md has a 'Three-tier test stack' section covering when each tier runs and quick-ref commands -- [ ] #2 agents/device-testing.md exists and covers: three-tier architecture, DevicePersona schema + capture flow, SystemState registry, TestRuntime + runner selection, tagging convention, how to write a T3 test -- [ ] #3 All 11 tasks TASK-301..TASK-311 have descriptions updated to reference @podkit/device-testing, DevicePersona, SystemState, and lima-test-vm runner -- [ ] #4 agents/device-testing.md cross-references packages/device-testing/README.md for package-level detail +- [x] #1 agents/testing.md has a 'Three-tier test stack' section covering when each tier runs and quick-ref commands +- [x] #2 agents/device-testing.md exists and covers: three-tier architecture, DevicePersona schema + capture flow, SystemState registry, TestRuntime + runner selection, tagging convention, how to write a T3 test +- [x] #3 All 11 tasks TASK-301..TASK-311 have descriptions updated to reference @podkit/device-testing, DevicePersona, SystemState, and lima-test-vm runner +- [x] #4 agents/device-testing.md cross-references packages/device-testing/README.md for package-level detail + +## Final Summary + + +## What shipped + +- `agents/testing.md` gained a `## Three-Tier Test Stack` section (~70 lines) placed between the `Per-OS Test Tagging` section (from TASK-321.05) and `Test Task Composition`.
