Summary

Fixes#522 — the GitHub Pages deploy job has been silently skipping on main pushes.

Root cause:deploy's if: condition (github.ref == 'refs/heads/main' && github.event_name != 'pull_request' && needs.ci-success.result == 'success') has no status-check function, so GitHub Actions applies its default implicit success() gate — which is affected by any legitimately-skipped job in the dependency graph, not just deploy's direct need (ci-success). Three jobs are intentionally skip-tolerated by ci-success's own logic: pr-size (skipped on every non-pull_request event, by design — it's PR-only governance), and rust-tauri/core-rust (skipped when their paths aren't touched). ci-success itself correctly computes success in these cases (it has its own if: always() plus explicit per-job tolerance), but deploy's bare if: inherits GHA's default skip-propagation regardless.

Verified via real run history, not just the reported symptom:

Fix:always() && !cancelled() && <existing explicit conditions> — matches the identical proven pattern already used in tauri-build.yml's bundle job for the same class of problem. Forces GitHub to evaluate deploy's own explicit condition (main, non-PR, ci-success.result == 'success') instead of deriving admission from whether any upstream job was skipped, while !cancelled() still refuses to publish from a genuinely cancelled workflow run.

Test plan

  • New regression test in tests/unit/workflowPolicy.test.ts asserts deploy's needs/if: structure directly against the broken scenario (pr-size/rust-tauri/core-rust skipped, ci-success success → deploy must still be admitted).
  • pnpm run workflow-policy:check — structural YAML validator passes.
  • YAML parse-verified the new if: >- block scalar resolves to the intended ${{ always() && !cancelled() && ... }} expression (no !-as-tag-indicator ambiguity).
  • pnpm run typecheck:single — clean.
  • pnpm run ci:prepushMIXED classification, all local checks pass.

Note on what this PR can't prove:deploy never runs on a pull_request event by design (github.event_name != 'pull_request' is one of its own conditions), so this PR's own CI cannot exercise the actual fix. The real acceptance evidence is a genuine post-merge main-push run showing real Deploy to GitHub Pages steps (Set up job / Deploy to GitHub Pages / Complete job), not conclusion: skipped — will verify that directly after merge before considering #522 closed.

Summary by Sourcery

Allow approved main-branch builds to reach GitHub Pages despite legitimately skipped upstream jobs.

Bug Fixes:

  • Ensure eligible GitHub Pages deployments on main-branch pushes are not skipped when optional upstream jobs are legitimately skipped.

Enhancements:

  • Keep cancelled workflows and pull-request events excluded while making ci-success the explicit deployment gate.

Documentation:

  • Update documented test counts to reflect the added workflow regression test.

Tests:

  • Add regression coverage verifying the deploy condition handles skipped optional jobs and requires a successful ci-success result.

CodeAnt-AI Description

Ensure approved main-branch builds reach GitHub Pages

What Changed

  • GitHub Pages deployment now proceeds on eligible main-branch pushes when required checks pass, even if unrelated jobs were legitimately skipped
  • Cancelled workflows and pull requests remain excluded from deployment
  • Added a regression test covering skipped optional jobs and the successful deployment path
  • Updated documentation to reflect the new test count

Impact

✅ Fewer skipped GitHub Pages deployments
✅ Fresher main-branch documentation
✅ Protected deployments from cancelled workflows

…eam jobs (#522)
deploy's if: condition lacked a status-check function, so GitHub
Actions' default implicit success() gate silently skipped the job
whenever any upstream job in the graph was legitimately skipped
(pr-size on every non-pull_request event, rust-tauri/core-rust on any
push that doesn't touch their paths) — even though ci-success itself
correctly computed 'success' via its own always()-gated tolerance
logic for exactly those three jobs.
Traced via real run history: #427 (2026-08-20) switched deploy's needs
from [build, e2e] to [ci-success], introducing the dependency; #428
was the first reproducible skip immediately after (Rust gates
skipped); #509 (2026-08-26, PR-size governance) made it apply to every
main push once pr-size joined ci-success's tolerated-skip set. GitHub
Pages has been serving a stale build since, correlating exactly with
whether the specific run's Rust-gate path happened to be relevant.
Adds always() + !cancelled() to deploy's if:, matching the identical
proven pattern already used in tauri-build.yml's bundle job — forces
GitHub to evaluate the job's own explicit condition (main, non-PR,
ci-success.result == 'success') instead of deriving admission from
the presence of any skipped job anywhere in the chain, while still
refusing to publish from a genuinely cancelled workflow run.
New regression test asserts deploy's needs/if: structure directly
against the exact main-push scenario (pr-size/rust-tauri/core-rust
skipped, ci-success success) that was silently broken.
Note: PR CI cannot itself prove this — deploy never runs on a
pull_request event by design. Acceptance evidence is a genuine
post-merge main-push run showing real Deploy to GitHub Pages steps,
not conclusion: skipped.

Reviewer's Guide

Updates the GitHub Pages deploy condition to bypass GitHub Actions’ implicit skip-propagation from legitimately skipped CI jobs, while still requiring a non-cancelled main-branch push and successful ci-success; adds structural regression coverage and synchronizes README test metrics.

Assessment against linked issues

IssueObjectiveAddressedExplanation
#522Ensure the GitHub Pages deployment job runs on successful non-pull-request pushes to the main branch even when legitimately skipped upstream jobs would otherwise trigger GitHub Actions' implicit skip-propagation.
#522Preserve the existing safety gates so deployment requires ci-success to succeed, is limited to main push-like events, and does not run for cancelled workflow runs.
#522Add regression coverage documenting and validating the workflow condition that prevents the deployment from being silently skipped.

The fix correctly addresses issue #522 by preventing GitHub Actions' default skip propagation from silently skipping the deploy job when upstream jobs like pr-size, rust-tauri, or core-rust are legitimately skipped. The always() && !cancelled() pattern matches the proven approach already used in tauri-build.yml and ensures deploy runs when ci-success reports success, regardless of which optional gates were skipped. The new regression test in workflowPolicy.test.ts validates all five conditions of the deploy gate, providing strong protection against future regressions.

📝 Walkthrough

Walkthrough

The CI deploy condition now evaluates after skipped prerequisites, blocks cancelled runs, and requires a successful ci-success result for non-PR pushes to main. A workflow policy test covers these conditions. README test metrics now report 7,168+ tests.

Changes

CI deployment gating

Layer / File(s)Summary
Deployment condition and policy validation
.github/workflows/ci.yml, tests/unit/workflowPolicy.test.ts
The deploy job uses explicit always(), !cancelled(), branch, event, and ci-success result checks. Tests assert the deployment dependencies and conditions.
Test count documentation

Four README sections now report 7,168+ tests.

Estimated code review effort: 2 (Simple) | ~10 minutes

Merge Risk:🔵 Low · up to 549dd

The change restores eligible GitHub Pages deployments while preserving cancellation protection, but the regression test may not reliably verify both safeguards because it can match text from a comment instead of the actual condition. The PR is mergeable with explicit owner awareness or a follow-up to scope assertions to the deployment expression.

Comment threadtests/unit/workflowPolicy.test.ts
Address CodeAnt AI + CodeRabbit review of #523: the test asserted
against extractJobBlock(workflowSource, 'deploy') — the whole raw job
block — which also contains the QNBS-v3 comment directly above if:,
itself mentioning "always()" and "!cancelled()". A regression that
strips either function from the real, executable if: line (while
leaving the comment untouched) would have kept passing.
Add extractJobIf(jobBlock) to the shared workflow-policy parser
utilities — handles both inline (if: <expr>) and folded block-scalar
(if: >-\n ...) forms already used across ci.yml/tauri-build.yml — and
scope the deploy test's assertions to its return value instead of the
whole block.
Verified the fix actually closes the gap: reverting the assertions to
extractJobBlock and manually stripping always() from the real if: line
(comment left intact) left the old test passing; with extractJobIf,
the same edit correctly fails it.
