AI summary

A new PR CI workflow (.github/workflows/pr.yaml) runs on every pull request to develop and runs only what the diff affects, on Linux, with escalation tiers for the expensive jobs. fw-lite.yaml keeps running on PRs for now (shadow phase); cutting it over to develop-only and making PR CI result a required check is a later PR.

How it decides what to run. nx with the official @nx/dotnet plugin sits at the repo root, graph-only (nothing builds or caches through nx). .github/scripts/affected.sh prints one JSON object with the affected .NET projects, viewer/extension booleans, an everything flag for shared-file changes (props, global.json, solution files, lockfiles) and the escalation tiers; task ci:affected gives the same answer locally. Any detector failure means everything is affected, with a warning annotation. The viewer and the Platform.Bible extension are nx projects via one project.json each; the tiers are tier-* pseudo-projects under .github/ci-tiers/ whose project.json holds the path rule (see the README there).

Jobs. detect; dotnet (builds FwLiteCore.slnf whole so the EF-model and generated-TS checks stay unconditional, then tests only the affected test projects via a generated FwLiteAffectedTests.slnf, Category!=Slow&Category!=Benchmark); viewer-checks (i18n drift, viewer-only svelte-check and eslint, prettier, vitest on Chromium only, vite build) and viewer-ui-tests (Playwright, Chromium; ci:webkit adds WebKit) as two jobs so wall clock is the max; extension-lint; escalations slow-tests, maui-windows, apple, android, e2e (compile and test only, no packaging or signing); summary (PR CI result). A ci:<tier> label pulls a tier in (ci:full = all) and re-triggers the run.

Also in this PR. Category=Slow on the tests that dominate the two slowest assemblies (Sena3SyncTests as a class, both CanSyncRandomEntries theories, BulkCreateEntriesPerformance, GetEntryIndex_LargeList_ReturnsCorrectIndex); task fw-lite:test-verified fixed (it always exited 1); develop-ui.yaml no longer triggers on viewer-only changes; a VITEST_CHROMIUM_ONLY switch in the viewer's vitest config; a root npm Dependabot group for nx/@nx/dotnet; .github/AGENTS.md documents the PR tier.

Footprint of the nx root. Root package.json, pnpm-lock.yaml and a settings-only pnpm-workspace.yaml (the frontend/ workspace stays where it is and is unaffected), nx.json, three project.json files plus seven tier folders, .nx/ and the root node_modules ignored.

Test plan

• actionlint clean on pr.yaml and develop-ui.yaml (done locally)
• task ci:affected matches the detect job's answer for this PR's diff
• Docs-only commit on this branch: only detect and PR CI result run
• One-project .NET change (e.g. backend/FwLite/LcmCrdt/): dotnet runs the affected test projects; slow-tests and e2e tiers fire
• Viewer-only change: viewer-checks and viewer-ui-tests only
• ci:full label: every job runs, including the escalations
• Wall clock per case recorded against the 10-minute target

Walkthrough

Adds Nx-based affected-project detection and a new pull-request workflow that selects .NET, viewer, extension, and platform checks from affected projects and CI tiers. Adds scripts for detection and filtered test solutions, classifies selected tests as slow, and updates frontend workflow configuration.

Priority: Normal

Estimated code review effort: 4 (Complex) | ~60 minutes

Change: Feature

Merge Risk: Moderate · up to f1be9

The new CI can fail when slow tests are explicitly requested and can skip intended checks for affected changes. Correct job selection before relying on this workflow for pull requests.

Full details: Title check

Explanation

The title "Add a PR CI workflow that runs only the affected FW Lite checks" matches the main change. The PR adds .github/workflows/pr.yaml, a pull-request CI workflow that uses Nx affected-project detection (.github/scripts/affected.sh) to run only the affected checks, with escalation tiers under .github/ci-tiers/. The title is specific and concise. It does not mention the secondary changes, such as the slow-test tags, the task fw-lite:test-verified fix, and the develop-ui.yaml trigger change. The description says those are expected in a single PR and the title does not need to cover every detail.

Full details: Description check

Explanation

The description matches the changeset. It describes the new PR CI workflow (.github/workflows/pr.yaml) and the Nx root setup (nx.json, package.json, pnpm-workspace.yaml). It also covers .github/scripts/affected.sh, the ci-tiers project.json files, the Category=Slow test tags, the develop-ui.yaml trigger change, the VITEST_CHROMIUM_ONLY switch, and the Dependabot group. The description is detailed and specific to the diff.

Full details: Docstring Coverage

Explanation

Docstring coverage is 18.18% which is insufficient. The required threshold is 80.00%. Docstring coverage is scoped to functions touched by this diff. Analyzed 11 functions across 7 files. (21 skipped: 21 unsupported.)

Resolution

Write docstrings for the functions missing them to satisfy the coverage threshold.

right now this would keep our normal CI and this new CI running. I suggest we disable the old CI before we merge this.

Review comments at @.github/scripts/affected.sh:
- Line 45: Update nx_json to preserve and surface Nx stderr when the command
fails instead of discarding it, while keeping stdout parsing and the existing
failure return behavior unchanged.
- Around line 59-60: Keep the existing project-based result from `nx_json`, and
union it with a separate affected-project query using `NX_LEGACY_AFFECTED=false`
and `--withTarget=ci-affected`. Update the result assembly to deduplicate the
combined project lists.

Review comments at @.github/workflows/pr.yaml:
- Line 96: Update the fallback condition for testProjects in the slow-test
project selection flow so an empty testProjects list uses coreTests when the
slow-tests tier is enabled, even if dotnet is false. Preserve the existing .NET
fallback behavior.
