4gray cfa602d5b1 ci: cut PR runner waste and harden workflow permissions (#1226)
Pipeline audit follow-up: reduce wasted runner time on PRs and tighten CI
security, without reducing what actually gets validated.

Runner-time waste:
- Concurrency with PR-only cancel-in-progress on CI, E2E, and docker-build,
  so a new push cancels the previous commit's still-running checks. Non-PR
  runs use the unique run_id as the group, because GitHub keeps at most one
  pending run per group even with cancel-in-progress: false — a shared ref
  group could silently drop a queued master run.
- paths-ignore for docs-only changes (Markdown, docs/, .plans/, .codex/,
  .claude/) on the Electron build matrix and the E2E suites; E2E also skips
  apps/website/**. The build workflow keeps apps/website/** because its Linux
  job builds the website to verify AppStream assets. Tag pushes are
  unaffected: GitHub does not evaluate paths filters for tags.
- PRs lint affected projects only; master pushes keep the full run-many.
  Lint-global inputs (eslint.config.mjs, tools/eslint/**) now mark all 41
  lint projects affected, including the run-commands targets database and
  packaging, so the max-lines baseline cannot be widened without lint.

Hardening:
- Explicit least-privilege permissions on CI, E2E, and build-and-make; the
  create-release job keeps its job-level contents: write. The repository
  default workflow token was switched to read-only.
- New actionlint job (image pinned by digest, shellcheck at warning+), with
  the shared-anchor false positive suppressed in .github/actionlint.yaml.
  Fixed one real finding: unquoted $GITHUB_OUTPUT.
- .github/dependabot.yml: weekly cadence, minor+patch grouped per ecosystem
  (npm, GitHub Actions, Docker), majors stay individual PRs.

Docs updated: CLAUDE.md, docs/architecture/nx-workspace-boundaries.md, and
docs/architecture/validation-map.md now describe affected-lint on PRs and the
E2E path-filter exceptions.

# Validation Map
This map records the lowest-cost validation commands agents should reach for
before broad CI-sized runs.
## Discovery
```bash
pnpm nx show projects --withTarget test
pnpm nx show projects --withTarget lint
pnpm nx show projects --withTarget e2e
```
## Unit And Type Checks
| Area | Command |
| ---------------------------------- | ----------------------------------- |
| Angular renderer entry points | `pnpm run typecheck:web` |
| Electron main process entry points | `pnpm run typecheck:backend` |
| Full unit suite (all projects) | `pnpm run test:unit:ci` |
| EPG data access | `pnpm nx test epg-data-access` |
| Workspace shell utilities | `pnpm nx test workspace-shell-util` |
| Shared SQLite schema/connection | `pnpm nx test database` |
| Packaging metadata | `pnpm nx test packaging` |
## Lint
```bash
pnpm run lint # nx run-many --target=lint --all
pnpm nx lint <project> # single project
```
The CI workflow (`.github/workflows/ci.yml`) lints affected projects on PRs
(`nx affected`) and every project on master pushes.
This enforces `@nx/enforce-module-boundaries` (scope/domain/type tag
constraints), the legacy bare-alias ban, and the `max-lines` file-size rule
(hard maximum 400 lines per TypeScript file). Files that predate the
`max-lines` rule are baselined in `tools/eslint/max-lines-baseline.mjs`; after
splitting a baselined file below the limit, regenerate the list with
`node tools/eslint/generate-max-lines-baseline.mjs`. Never add new files to
the baseline.
## Coverage Tiers
Use `tools/coverage/coverage-policy.json` as the source of truth for coverage
ownership. Every project with a `test` target must be classified in a tier;
`pnpm run coverage:policy:check` (part of `coverage:ci`) fails CI when a new
project is missing from the policy, a listed project no longer exists, or a
Tier A entry has no test target. CI runs Tier A with coverage (uploaded to
Codecov) and each Tier B/C project's `validationCommand` (falling back to
`nx test`) without coverage; projects with an `e2e` target are skipped there
because the E2E workflow already runs them on every PR that touches app code.
Docs-only changes (Markdown, `docs/`, `.plans/`, `.codex/`, `.claude/`) and
`apps/website/**` changes skip the E2E workflow via `paths-ignore` — for those
PRs no E2E validation runs in CI, which is intentional: they cannot affect app
behavior.
| Tier | Rule | Validation |
| --- | --- | --- |
| A | Product/runtime Angular, Electron, backend, data-access, portal, playlist, workspace, playback, EPG, and shared UI code collects source coverage. | `pnpm run coverage:ci` |
| B | Validate behavior without percentage coverage, such as `website`, `packaging`, and Playwright E2E projects. | `pnpm nx test website`, `pnpm nx test packaging`, or the closest E2E target |
| C | Excluded from the source coverage baseline, such as mock servers, test helper libraries, and untested feature shells. | Validate through dependent flows, or add focused tests when changing behavior directly |
`apps/website` is an Astro marketing site. Its useful signal is a successful
static build plus targeted output checks, not a merged code coverage percentage.
Projects with a test target but no specs, such as `remote-control-web` and
`remote-control` today, should not be in Tier A until focused specs exist.
For local coverage inspection:
```bash
pnpm run coverage:unit:ci
pnpm run coverage:merge
pnpm run coverage:health
```
The merged report is written to `coverage/merged/` as HTML, LCOV, Cobertura,
and JSON summary output. CI uploads the merged Tier A report to Codecov with the
`unit` flag and keeps the HTML report as a GitHub artifact.
## E2E
| Area | Command |
| --------------------- | ----------------------------------------------- |
| Web app browser flows | `pnpm nx run web-e2e:e2e -- --project=chromium` |
| Electron flows | `pnpm nx run electron-backend-e2e:e2e` |
Use atomized E2E targets when available, for example
`pnpm nx run web-e2e:e2e-ci--src/xtream.e2e.ts`.
Playwright coverage is measured semantically by tags and critical journeys, not
by a source-line percentage. E2E reports should use tags such as `@critical`,
`@electron`, `@web`, `@xtream`, `@stalker`, `@m3u`, `@search`, `@epg`,
`@persistence`, `@settings`, `@pwa`, and `@self-hosted`.
After an E2E run, generate the semantic summary with:
```bash
pnpm run coverage:e2e:summary
```
For local investigation only, Chromium browser V8 coverage can be explored with:
```bash
pnpm run coverage:e2e:v8:web
```
## I18n
```bash
pnpm run i18n:check
```
The i18n check is non-mutating. It compares every locale file in
`apps/web/src/assets/i18n/` against `en.json` and fails on missing or extra keys.
Identical English fallback values are reported as warnings by default; use
`node tools/i18n/check-drift.mjs --fail-on-identical` for a stricter translation
audit.
## Logging
Runtime playback and EPG debug logs should use the existing logger or trace
helpers instead of unconditional `console.log`. Electron external-player traces
are gated by:
```bash
IPTVNATOR_TRACE_PLAYER=1 pnpm run serve:backend
```
