The gap

ci.yml filtered both triggers to main:

on:
  push:
    branches: [main]
  pull_request:
    branches: [main]

A PR targeting release/v1.7.0 matches neither, so the whole pipeline is skipped. What a release PR actually shows today is six checks, all from apps that trigger regardless of this filter — DCO, CodeRabbit, SonarCloud, code-ranker — and nothing from this workflow:

Not running on release branches
Test (Python 3.11 / 3.12 / 3.13 / 3.14)
Coverage (≥90%)
Pylint
Dead Code Scan
Enforcement Gates (seeded violations must fail)
Spec Coverage
Validate Artifacts (× 4 Python versions)
Validate Kits (× 4 Python versions)
Version Consistency

Found while preparing v1.7.0 (#192). The CI workflow had never run on release/v1.7.0-integration — not once across the branch's history.

Why it matters

This is backwards for the release process the branches exist to serve. A release branch is cut from the previous tag, reviewed and tested there, and only then tagged — so the one branch whose entire purpose is being tested before a tag was the only one the pipeline did not cover.

For v1.7.0 that meant the evidence the release passes (5,723 tests, cfs validate, the spec-coverage gate) was a local run on one contributor's machine, with nothing in GitHub to corroborate it.

The change

on:
  push:
    branches: [main, 'release/**']
  pull_request:
    branches: [main, 'release/**']

release/** rather than a single branch name, so 1.7.1 and everything after it is covered without another edit.

Note on where this has to live

The same change is already on the v1.7.0 branch in #192, and that is not duplication. A pull_request trigger is evaluated against the PR's own workflow file, so only the copy on the release branch makes the pipeline run on the release PR before it merges. This PR is what gives every future release branch the same behaviour from the moment it is cut.

Cost

More runner time: pushes to release branches now run the full matrix. That is the point — it is the same work the pipeline already does for main, applied to the branch a tag is actually created from.

Summary by CodeRabbit

  • Chores
    • Continuous integration checks now run for release-candidate branches in addition to the main branch.
    • Release branches receive the same automated testing, linting, coverage, and artifact validation before tagging.

`on:` filtered both `push` and `pull_request` to `main`, so a PR targeting a
release branch matched neither. Release PRs showed only the checks that come
from apps and trigger regardless (DCO, CodeRabbit, SonarCloud, code-ranker), and
none from this workflow: no tests on any Python version, no Pylint, no Coverage,
no Dead Code Scan, no Validate Artifacts or Validate Kits.

Found while preparing v1.7.0 (#192): the `CI` workflow had never run on
`release/v1.7.0-integration`, not once across the branch's history.

That is backwards for the release process these branches exist to serve. A
release branch is cut from the previous tag, reviewed and tested there, and only
then tagged -- so the one branch whose whole purpose is being tested before a tag
was the only one the pipeline did not cover, and the evidence that it passed was
a local run on a contributor's machine.

`release/**` rather than a single branch name, so 1.7.1 and everything after it
is covered without another edit. The same change is on the v1.7.0 branch in
#192, because a `pull_request` trigger is evaluated against the PR's own
workflow and that is what makes the pipeline run on the release PR itself.

Release branch trigger release/** never matches the project's documented vX.Y.Z-beta / vX.Y.Z branch naming

Severity: Critical

Problem
CONTRIBUTING.md line 146 instructs git checkout -b vX.Y.Z-beta and the Branch and Release Workflow diagram (lines 188–191) shows release branches named vX.Y.Z-beta and vX.Y.Z. The newly added glob release/** matches only branches whose name starts with the literal string release/. A branch named v1.2.0-beta or v1.2.0 does not start with release/, so the pattern never fires.

Reproduction, impact, suggested fix, verification

How to reproduce

  1. Follow CONTRIBUTING.md: git checkout -b v1.2.0-beta. 2. Push the branch. 3. Observe that no CI run is triggered — v1.2.0-beta does not match release/**.

Expected behavior
The trigger glob matches every branch that follows the documented release naming convention, so that CI runs on pushes to and PRs targeting those branches.

Actual behavior
The glob release/** matches zero branches ever created under the documented convention; the entire change is a no-op for the project's actual release workflow.

Documented branch: v1.2.0-beta
Trigger pattern: release/**
Match result: NO MATCH → CI never runs for documented release branches

Impact
The stated goal — running tests, lint, coverage, and artifact validation on release branches before tagging — is not achieved. Release branches continue to receive only the third-party app checks (DCO, SonarCloud, code-ranker) that were already running, exactly as before this PR.

Suggested correction
Change the glob to match the documented naming convention, e.g. 'v[0-9]*' or 'v*', which matches both v1.2.0-beta and v1.2.0. Alternatively, update CONTRIBUTING.md to adopt a release/X.Y.Z naming convention if that is the intended change.

How to verify
After correction, push a branch named v1.2.0-beta and confirm a CI workflow run appears in the Actions tab for that push.

pull_request.branches filter targets an undocumented hotfix scenario, not the stated release-PR use case

Severity: Minor

Problem
GitHub Actions evaluates pull_request.branches against the PR's base (target) branch, not the head (source) branch. A PR from a release branch into main has base=main, which already matched before this change. Adding release/** to pull_request.branches enables CI only for PRs that target a release/** branch (i.e., hotfix PRs into a release branch). The PR comment describes the missing CI as being on the release branch itself (push side), which is correctly addressed by the push.branches change — the pull_request.branches addition addresses a separate, undocumented scenario.

Reproduction, impact, suggested fix, verification

How to reproduce

  1. Create a release branch release/1.2.0. 2. Open a PR from release/1.2.0 into main. 3. Observe that base=main, which matched pull_request.branches: [main] before this PR — CI already ran on that PR.

Expected behavior
The pull_request.branches addition should implement the rationale stated in the comment, or the comment should describe the hotfix-targeting-release-branch scenario it actually enables.

Actual behavior
The pull_request.branches: release/** addition enables CI for PRs whose base is a release/** branch (hotfix PRs), while the stated motivation (release branch lacking test/lint/coverage) is fully addressed by the push.branches change alone.

Before: push→release/** ✗CI | PR(head=release,base=main) ✓CI(already via main)
After: push→release/** ✓CI | PR(head=any,base=release/**) ✓CI(NEW, undocumented)
Stated gap: push→release/** ✗CI (fixed by push change, not PR change)

Impact
The comment misleads future maintainers about what the pull_request.branches line does. Additionally, if the actual branch naming is vX.Y.Z-beta (not release/*), both additions may be dead on arrival.

Suggested correction
Either: (a) document that pull_request.branches: release/** is intentional for hotfix PRs targeting release branches, or (b) remove it if only the push-side gap was the intent. Also align the PR comment to describe the actual semantics.

How to verify
Create a test PR with base=release/x.y.z and confirm CI triggers; create a PR with head=release/x.y.z and base=main and confirm CI was already running before this change.

Test job retains checkout credentials while executing repository-controlled Make targets

Severity: Minor

Problem
The gates job sets persist-credentials: false with the explicit comment 'Keep the job token out of.git/config so the test corpus this job executes cannot read it back'. The test job runs the same pattern — make install and make test against repository-controlled Makefiles — but has no persist-credentials: false. The GitHub token therefore remains in .git/config during the full test run. This pre-existing asymmetry now also applies to the newly admitted release/** branches.

Reproduction, impact, suggested fix, verification

How to reproduce

  1. Push to any release/** branch (or open a PR targeting one). 2. CI triggers the test job. 3. actions/checkout@v4 with no persist-credentials: false writes the workflow token into .git/config. 4. Any code path reached by make install or make test can read that token.

Expected behavior
The test job should apply persist-credentials: false for the same reason the gates job does — both execute repository-controlled code with the checkout token in scope.

Actual behavior
The test job retains the checkout token throughout make install and make test; the gates job correctly strips it. The asymmetry is unaddressed and now extends to release branches.

test job: checkout(token persisted) → make install → make test [token readable]
gates job: checkout(persist-credentials:false) → make install → make test-gates [token cleared]

Impact
A compromised dependency pulled by make install, or a malicious path exercised during make test, can exfiltrate the workflow token. For release branches the token may have broader write permissions than for a fork-originated PR.

Suggested correction
Add persist-credentials: false to the test job's actions/checkout step, matching the gates job's existing pattern.

How to verify
After adding persist-credentials: false to the test job's checkout step, inspect the runner's .git/config mid-run and confirm no extraheader credential entry is present.

SonarQube action uses mutable @v6 tag while the repository's own SHA-pin policy is demonstrated by code-ranker

Severity: Minor

Problem
.github/workflows/code-ranker.yml line 7 explicitly documents a 'supply-chain hardening' rationale and pins to 42c2fba1acd7c99a71875c8eefa171224d8e683c. .github/workflows/ci.yml line 120 uses SonarSource/sonarqube-scan-action@v6, a mutable major-version tag that resolves to whatever commit SonarSource last pushed to that tag. No policy document grants an exemption. The diff expands the sonarqube job to execute on release/** branches — precisely the branches the PR describes as the last gate before a version tag.

Reproduction, impact, suggested fix, verification

How to reproduce

  1. Push to a release/** branch. 2. CI triggers the sonarqube job. 3. The job runs SonarSource/sonarqube-scan-action@v6, resolving the tag at runtime. 4. If SonarSource updates @v6 between CI runs, different code executes with access to SONAR_TOKEN.

Expected behavior
The SonarQube action is pinned to an immutable commit SHA, consistent with the SHA-pin policy demonstrated by code-ranker.yml, especially for CI that now runs on release branches.

Actual behavior
SonarSource/sonarqube-scan-action@v6 is a mutable label; a tag update or compromise at SonarSource silently changes the code that runs with SONAR_TOKEN in the environment.

code-ranker.yml: uses:...@42c2fba1acd7c99a71875c8eefa171224d8e683c ← immutable
ci.yml sonarqube: uses: SonarSource/sonarqube-scan-action@v6 ← mutable

Impact
A changed or compromised @v6 tag executes arbitrary code with SONAR_TOKEN in scope during release CI, a higher-value target than ordinary feature-branch CI.

Suggested correction
Pin the action to its current commit SHA: look up the SHA for the v6 tag on the SonarSource GitHub repo and replace @v6 with @<sha> # v6.

How to verify
After pinning, confirm ci.yml line 120 references a full 40-character SHA. Run git log --oneline on the SonarSource repo to cross-check the SHA matches the intended v6 release.

SonarQube job reports success without scanning when SONAR_TOKEN is absent

Severity: Minor

Problem
The sonarqube job (ci.yml lines 101–121) sets SONAR_TOKEN from secrets at the job level but has no job-level if: env.SONAR_TOKEN != '' guard. The checkout step (line 108) runs unconditionally. The two substantive steps — artifact download (line 113) and sonarqube scan (line 119) — are each individually guarded by if: env.SONAR_TOKEN != ''. When the secret is absent or empty, the job starts, completes checkout, skips both scan steps, and exits with status success. The CI dashboard displays SonarQube as ✓ passed with no indication that no scan ran.

Reproduction, impact, suggested fix, verification

How to reproduce

  1. Push to a release/** branch where SONAR_TOKEN is not configured (e.g., secret scoped only to main environments, or absent in a fork/new repo). 2. CI triggers the sonarqube job. 3. Checkout completes. 4. Both scan steps are skipped silently. 5. Job finishes green.

Expected behavior
When SONAR_TOKEN is absent, the sonarqube job should either be skipped entirely (via a job-level if:) or fail with an explicit error, so the CI dashboard accurately reflects that no quality scan occurred.

Actual behavior
The job always starts and always shows green regardless of whether a scan ran, making 'SonarQube: passed' meaningless as a release-gate signal when the token is absent.

SONAR_TOKEN absent:
job starts (no job-level if)
→ checkout ✓ (unguarded)
→ download-artifact SKIPPED (step-level guard)
→ sonarqube-scan SKIPPED (step-level guard)
→ job result: SUCCESS ← misleading green

Impact
Release CI can present SonarQube as passed even though no quality scan occurred, undermining the gate the PR claims to establish for release branches before tagging.

Suggested correction
Add a job-level if: env.SONAR_TOKEN != '' (or equivalent) to the sonarqube job, so the job is skipped — not silently succeeded — when the token is absent. Alternatively, add a dedicated step that explicitly fails with an error message when the token is missing.

How to verify
Run CI on a branch with SONAR_TOKEN removed from secrets; confirm the sonarqube job shows as skipped (or failed) rather than green.

Version consistency check compares release branches against an advancing origin/main, producing spurious 'version not bumped' failures

Severity: Major

Problem
scripts/check_versions.py line 184 sets --base to origin/main. The check_kit_version_bump function (line 129) diffs kit files against that base; line 149 reads the conf.toml version from origin/main; line 168 fails if the release branch's version is ≤ origin/main's version. When a release branch is cut from main at tag N and main subsequently bumps a kit to version N+1, the release branch's kit still has version N. git diff origin/main -- kits/foo/ shows conf.toml as changed (N vs N+1), and the check reports 'version not bumped' — even though no change was made to that kit on the release branch. The versions CI job (ci.yml lines 148–161) passes no --base override, so this default always applies.

Reproduction, impact, suggested fix, verification

How to reproduce

  1. Create v1.2.0-beta from main when kit foo is at version 3. 2. Merge a PR to main that bumps kit foo to version 4. 3. Push a commit to v1.2.0-beta. 4. CI runs the versions job; git diff origin/main -- kits/foo/ shows conf.toml as changed; base version=4, current=3; check reports 'files changed but conf.toml version not bumped'.

Expected behavior
The version bump check compares only changes made on the release branch since it was created, not all differences between the release branch and an advancing origin/main.

Actual behavior
origin/main is used as the comparison base unconditionally; the versions job on a release branch produces false-positive errors for every kit that main bumped after the branch point.

main: A(v3) ──bump──> B(v4) ──> origin/main HEAD
release: A(v3) ──────────────────> HEAD
git diff origin/main: conf.toml differs (4 vs 3) → FALSE POSITIVE error

Impact
Release CI can fail spuriously on the versions job for every kit modified on main since the release branch was cut, blocking or distracting release validation with errors unrelated to release-branch content.

Suggested correction
In the versions CI job, pass --base set to the merge-base between the release branch and main, e.g.: make check-versions BASE=$(git merge-base HEAD origin/main) and thread that into check_versions.py via --base. Alternatively, skip the kit-bump check entirely when running on a release branch by detecting the branch pattern.

How to verify
Reproduce step 4 above after the fix; confirm the versions job passes on the release branch even though main has a later kit version.

The core change is correct — adding release/** to push.branches closes the genuine gap where release branches ran no pipeline tests before tagging. Approving. Four minor observations are threaded inline; none block merging, but they're worth a follow-up pass:

  • pull_request.branches targets hotfix PRs, not release PRspull_request.branches matches the PR's base, so release/** here covers PRs into a release branch, not the release-branch push path the commit comment describes. The push side is the right fix; this addition is incidental. thread

  • test job keeps credentials in .git/config during Make execution — the gates job explicitly drops them with persist-credentials: false; test doesn't, leaving the token readable by any Makefile target during the run. Now applies to release/** branches as well. thread

  • SonarQube action pinned to mutable @v6 tagcode-ranker.yml SHA-pins its actions with an explicit supply-chain rationale; ci.yml line 120 uses a floating major-version tag for the SonarQube scan, which now runs on the pre-tag release branches. thread

  • SonarQube job exits green with no scan when SONAR_TOKEN is absent — the two scan steps are individually gated but the job itself is not, so a missing secret produces a ✓ on the dashboard with nothing actually scanned. thread

Changes requested — this reintroduces the exact gap CI was trying to close, just moved: the release branch trigger and the version check it now runs alongside don't match how this project actually cuts releases.

  • release/** glob never matches real release branches — CONTRIBUTING.md and the branch/release diagram both name release branches vX.Y.Z-beta / vX.Y.Z (e.g. v1.2.0-beta), which doesn't start with release/. As written, CI still never runs on a release branch — the trigger looks fixed but isn't. (comment)
  • Version check will false-fail on every release branch once main moves oncheck_versions.py diffs against origin/main by default, with no --base override in the versions CI job. A release branch cut from main keeps its kit at version N; if main bumps that kit to N+1 afterward, the check reads the diff as "version not bumped" and fails even though the release branch never touched that kit. (comment)

Both need fixing before this can merge: the branch pattern has to actually match the documented naming, and the version-check base needs to compare against the branch's own fork point (or an equivalent baseline), not a moving main.
