bvandeusenandClaude Opus 5 fa0827f668 ci: pin the download mirror to v6, not v5 — match on @actions/artifact
The previous pin matched the two actions by their own version numbers, which
is meaningless: upload-artifact and download-artifact release on unrelated
cadences. upload v5 bundles @actions/artifact ^4.0.0; download v5 bundles
^2.3.2. "v5 and v5" was in fact a mismatched pair.

download v6 is the tag that puts ^4.0.0 on both sides — and ^4.0.0 is the
library major just proven against this instance by the upload side
(thoughtsync run 3094: two artifacts listed, downloaded and extracted
intact). ^2.3.2 has never been exercised here.

Not v7: that major is a runner requirement rather than a feature change. It
moves to runs.using: node24 and upstream requires runner >= 2.327.1 for it,
which act_runner does not claim to satisfy. Everything pinned stays node20.

ci-requirements.md now carries the version/runtime table and the reasoning,
so the next person matches on the library instead of the tag number.

# CI Requirements — Minstrel
> Copy of [the template](https://git.fabledsword.com/bvandeusen/CI-runner/src/branch/main/docs/requirements-sheet.template.md).
> Family-wide policy: `ci-runners.md` in the FabledRulebook.
## Runtime images
Minstrel's four workflows consume two CI images:
```
git.fabledsword.com/bvandeusen/ci-go:1.26
git.fabledsword.com/bvandeusen/ci-flutter:3.44
```
- `ci-go:1.26` — Go server tests (`.gitea/workflows/test-go.yml`), web SPA tests (`.gitea/workflows/test-web.yml`), and the release container build (`.gitea/workflows/release.yml`).
- `ci-flutter:3.44` — Flutter client tests + debug/release APK builds (`.gitea/workflows/flutter.yml`).
## Image deps used
### From `ci-go:1.26`
- **Go** (1.26 toolchain) — `go vet`, `go test -race`, `go build`, `go mod`.
- **Node + npm** — `npm ci` and `npm test` / `npm run check` in `test-web.yml`.
- **golangci-lint** — lint pass in `test-go.yml`.
- **docker CLI** — bridge-IP discovery of the per-job Postgres service container in `test-go.yml` integration job (via the runner's shared `/var/run/docker.sock`).
- **docker buildx** — release container build + push in `release.yml`.
- **curl** — release-asset polling / upload in `release.yml`.
### From `ci-flutter:3.44`
- **Flutter** (3.44 stable channel) — `flutter pub get`, `flutter analyze --fatal-infos`, `flutter test`, `flutter build apk` (debug + signed release).
- **Dart** — `dart run tool/gen_tokens.dart`, `dart run build_runner build` (drift codegen).
- **Android SDK + NDK + cmdline-tools + build-tools** — APK assembly + signing.
- **Java 25** — Gradle / Android build.
- **git** — `actions/checkout@v4` baseline (and any shell git operations).
- **base64 + curl** — keystore decode + release-asset upload in the tag-build path.
## Per-job tool installs
None.
## Notes
- **Label/image split.** Workflows keep `runs-on: go-ci` / `runs-on: flutter-ci` as the scheduling label per the [`ci-runners.md`](https://…/FabledRulebook/ci-runners.md) "label = scheduling handle, image = `container.image`" pattern. The labels are intentional handles, not toolchain assertions.
- **Integration-job docker-socket dependency.** `test-go.yml`'s integration job uses the runner's shared docker socket (`/var/run/docker.sock`) to bridge-IP-discover the per-job Postgres service container by name + network intersection — the dev compose's `minstrel-postgres-*` containers are explicitly skipped as belt-and-suspenders. Depends on `act_runner.valid_volumes` whitelisting the socket; if that ever stops auto-mounting, integration tests fail at the `docker inspect` step.
- **Go toolchain pin.** `go.mod` is on `go 1.25.0` because `golang.org/x/crypto v0.51.0` declares 1.25 as its minimum. `ci-go:1.26` satisfies this with headroom. Future `x/crypto` bumps that move the Go floor should be paired with an image-tag bump in this file + the workflows.
- **In-app update channel polling.** `release.yml` polls Gitea's release-asset API for up to 15 min on tag pushes to fetch the APK that `flutter.yml` is concurrently attaching to the same release. The asset eventually appears because `flutter.yml` and `release.yml` run in parallel on the same tag; if the polling times out, the server image ships without the bundled update channel (graceful degradation, not a build failure).
- **Cache server reachability.** `test-web.yml` does NOT use `cache: 'npm'` on `actions/setup-node` — the Gitea Actions cache server isn't reachable from this runner's container network and `setup-node` was burning ~4m41s on ETIMEDOUT before failing open. With the migration to `ci-go:1.26`, `setup-node` is removed entirely (Node is in the image). The cache concern reappears if a future change re-introduces a network-dependent action.
- **Artifacts — use the mirrored actions, never `actions/{upload,download}-artifact`.**
```yaml
uses: https://git.fabledsword.com/bvandeusen/upload-artifact@cb8afe72b42edc798abfb8fcb556cf660d894245
uses: https://git.fabledsword.com/bvandeusen/download-artifact@8d4e9521a5f7e5f8b6351f341f719f9f45a92a3a
```
Upstream's `@v4+` cannot work against this instance and no server-side change
will help: `isGhes()` rejects any hostname that isn't `github.com` /
`*.ghe.com` / `*.localhost` and throws before it opens a connection, so the
server is never asked what it supports. `@v3` is worse — it reports success,
and Gitea then serves artifacts back only through the v4 API
(`content_encoding = application/zip`), so a v3 upload is stored but invisible
to every retrieval path. A green job producing nothing retrievable; that is how
72 unreachable artifacts accumulated on this repo. Scribe issues 2255 / 2270.
Both are pull mirrors of the Forgejo project's forks
(`code.forgejo.org/forgejo/{upload,download}-artifact`, one commit on upstream
disabling that check), mirrored so CI depends on commits we hold and pinned by
SHA because the mirrors auto-sync every 8h — a moved upstream tag would
otherwise silently change what runs.
**Match the pins on `@actions/artifact`, not on the actions' own version
numbers.** The two actions release on unrelated cadences, so equal version
numbers do NOT mean a compatible pair — upload `v5` bundles `@actions/artifact`
^4.0.0 while download `v5` bundles ^2.3.2. The pins above are upload **v5** and
download **v6**, which is the pairing that puts ^4.0.0 on both sides. This
matters because `release.yml` is a producer/consumer pair — `android-release`
uploads `minstrel-apk`, `image-release` downloads it — and a protocol mismatch
across it yields an empty listing rather than an error, exactly the silent
failure this entry exists to prevent.
| tag | `@actions/artifact` | runtime |
|---|---|---|
| upload v4 | ^2.1.1 | node20 |
| **upload v5** ← pinned | **^4.0.0** | node20 |
| download v4 | ^2.1.1 | node20 |
| download v5 | ^2.3.2 | node20 |
| **download v6** ← pinned | **^4.0.0** | node20 |
| download v7 | ^5.0.0 | **node24** |
The only true protocol break in this history was **v3 → v4** (upstream:
"Downloading artifacts that were created from `actions/upload-artifact@v3` and
below are not supported"); v4-and-up are one family. Later majors are mostly
ergonomics and runtime — upload v4 forbids re-uploading a name and caps a job
at 500 artifacts; download v5 made by-ID extraction match by-name.
**Do not jump the download pin to v7.** That major is a runner requirement, not
a feature change: it moves to `runs.using: node24` and upstream states it
"requires a minimum Actions Runner version of 2.327.1 … if you are using
self-hosted runners, ensure they are updated before upgrading." act_runner is
not GitHub's runner and makes no such version claim, so node24 is unverified
here. Everything currently pinned is node20.
Upload steps set `if-no-files-found: error` rather than the default `warn`, so
an upload that matches nothing fails its own job instead of failing the
consumer later.
Retrieval: `GET /api/v1/repos/{owner}/{repo}/actions/runs/{run_id}/artifacts`
for the id (global run id, not the repo-scoped run number), then
`…/actions/artifacts/{id}/zip`. The workstation has no `unzip` — use
`python3 -m zipfile -e`.
- **Friction asks.** None pending. The two images cover everything Minstrel needs.
