Make the Python Coverage Selector Explicit and Name D4.5's Second Route

[ptr727]

Settles two deferred contract defects, #1199 and #1214. Both were found by adversarial passes on earlier pull requests and both were left for a change that could touch CI behaviour rather than wording alone.

D1.6, the Python coverage invocation

#1199's headline is false, and the live runs say so. It reported that pytest --cov-report=xml collects nothing so no Python repo in the fleet reports coverage. The first half is true, the second is not. Financial-Modeling and aiopurpleair each log Coverage XML written to file coverage.xml and upload it, because each carries a --cov=<package> entry in its own pyproject addopts. homeassistant-purpleair has no uv.lock, so the step's own if never fires there, and PlexCleaner's Python subtree and ESPHome-Config are lint-only.

The real defect is narrower. D1.6 and spec/project-types.json both documented the bare invocation as the thing that collects coverage, and it does not: pytest-cov reports on what --cov selects, so --cov-report=xml alone measures nothing, writes no file, and exits zero. A repo onboarded by following D1.6 literally therefore reports nothing while its gate stays green, which is the failure D1.6's own Prevents clause names. Nothing downstream notices, because the upload is best-effort by design and reads a missing file exactly as it reads a healthy run.

So the contract now states the three obligations that were implicit, that the repo references pytest-cov, selects the coverage source in its own pyproject.toml, and leaves the report at the root path the upload step already reads, and the validator fails the test step when that file was not written.

The step deletes any coverage.xml before the run, so the check proves this run wrote one rather than that a file exists. Without that, a repo committing the report satisfies the guard while measuring nothing, which is the same false green in a new place. Proven by removing the delete and watching that case pass.

Adding --cov to the shared validator was the obvious fix and is the wrong one. Alongside a repo's own --cov=<package> it widens the measured set to include tests/, which moves every existing repo's percentage and would break a repo running fail_under = 100.

D4.5, the recovery a moved tip forecloses

#1214 assumed settling this needed a live publish against a real registry. It does not. 5B settles a question of this shape from the YAML, and the YAML answers this one. publish-release.yml passes ref: ${{ github.sha }}, and every build leaf checks out needs.get-version.outputs.GitCommitId. Re-run all jobs replays a run under the original event's GITHUB_SHA, so get-version recomputes the same version, the leaves rebuild the same commit, the package artifact D5.2 deleted is rebuilt and re-uploaded, and publish-<target> retries the push. What stays open is only whether the registry accepts the retried push, and no route settles that in advance, the prescribed re-dispatch included.

So D4.5 now names two recoveries and says which case each covers, rather than one recovery and an implication that the other case is beyond repair. Three qualifications ship with it: D4.4 and 5B's S9 describe a re-run whose predecessor push succeeded, GitHub allows a re-run only within 30 days, and --failed is unreliable because D5.2's delete has usually taken the artifact its download needs.

Two claims in the surrounding sentences were false and are corrected with it. "Leaves the first release without its package" is wrong for a NuGet caller, since D4.3 in the same item has the NuGet leaf uploading a release-asset-* carrying the package. And "since NBGV derives the version from git height" was attached to the claim that a re-dispatch builds the new tip, which git height does not explain.

#1214's own claim that 5C reserves a real registry push for the maintainer is not in 5C. 5C reserves the deploy ref gate dispatch and nothing else, so that citation was dropped rather than carried over.

Reach

Financial-Modeling calls validate-task.yml at a pinned hub release and picks the guard up at its next Dependabot bump. aiopurpleair still carries its own copy of the file, so it gets nothing here until it adopts the caller stub. Neither goes red: both carry a selector, pytest-cov, a uv.lock, and no [tool.coverage.xml] redirect. The precondition a Python adopter now owes is recorded on Stage 2's tracker in docs/reusable-workflows.md.

The hub has no tests/ and no uv.lock, so it cannot smoke-test this itself. That is the lint-only carve-out working, not drift, but it means CI here exercises the prose and not the guard.

Verification

Guard measured on a real pytest tree in every direction: no selector writes no file and exits zero, a selector writes it, a bogus selector writes nothing, absent pytest-cov exits 4, a [tool.coverage.xml] redirect leaves the root path empty, and a committed coverage.xml passes the pre-delete version and reds the shipped one. Full gate set green: 1046 script self-tests, spec/validate.py, build_dist.py --check, prose, eol, eol-coverage, sha-pin, actionlint, markdownlint, editorconfig-checker.

The three changed carried canonical units each carry a recorded pass, and the branch carries a recorded diff review.

Review cost, stated plainly

The D4.5 passage took six adversarial rounds and every round but the last introduced a defect the next one caught, twice by correctly applying the previous round's advice. The durable lesson is that prose stating a rule on top of a mechanism fails differently from prose stating the mechanism: when the mechanism turned out to be unverifiable, re-deriving the rule from what was left produced a claim nothing supported, and deleting the rule was the fix.

Nineteen pre-existing defects those passes surfaced are being filed separately rather than fixed here.

High-Level Assessment

The following are alternative approaches to this PR:

1. Add shared bare --cov

• ➕ Centralizes coverage activation in the reusable validator.
• ➕ Requires no repository-specific pytest configuration contract.
• ➖ Widens existing repositories' measured set, potentially including tests.
• ➖ Changes established percentages and can break strict fail-under thresholds.
• ➖ Cannot reliably identify each repository's intended first-party package.

2. Pass coverage source as workflow input

• ➕ Makes the selected package explicit at each validator call site.
• ➕ Allows centralized construction of the pytest command.
• ➖ Adds reusable-workflow API surface and migration work across callers.
• ➖ Duplicates project metadata already naturally owned by pyproject.toml.
• ➖ Complicates repositories with multiple packages or custom coverage settings.

Recommendation: Keep the PR's repository-owned selector and fresh-file guard. It preserves existing coverage denominators, supports varied Python layouts, and converts missing measurement into a clear CI failure without making Codecov availability gate the build. A shared bare selector was correctly rejected because it changes coverage semantics.

Code

WORKFLOW.md[157]

+- **D1.6 Coverage is reported to Codecov (C# and Python).** Input: a C# or Python repo's validation/test job. Output: tests run with coverage collection (`dotnet test --coverage --coverage-output-format cobertura --results-directory ./coverage` or `pytest --cov-report=xml` over a repo whose own pytest configuration selects what to measure) and a `codecov/codecov-action` step uploads it, **best-effort** (`continue-on-error` and/or `fail_ci_if_error: false`, so a Codecov outage or an absent token never reds the gate). `CODECOV_TOKEN` lives in the repo's **actions** and **dependabot** secret stores, the second because a run triggered by a Dependabot PR reads the Dependabot store and the upload would otherwise skip silently on every bot PR, and a caller passing it names it (`secrets:` with `CODECOV_TOKEN: ${{ secrets.CODECOV_TOKEN }}`), the way every hub task's declared secrets are passed, since `secrets: inherit` is documented for a caller in the same organization or enterprise and this fleet is a personal account, so a cross-repository call names each secret it passes. A call by local path stays inside one repository and may inherit instead. The publisher stub's validation job names the secret and every pull request stub's validation job passes no `secrets:` key at all, so a repo whose coverage must reach Codecov from its pull requests adds the mapping there itself. Required for **every** C# and Python repo that has tests. That C# invocation runs under **Microsoft.Testing.Platform**, which an MTP-based test project on the .NET 10 SDK and later requires, since running one through the VSTest target fails outright. A repo whose test project is MTP-based, in practice any repo on xunit.v3 4.0.0 or later, therefore also ships a root **`global.json`** declaring `{"test": {"runner": "Microsoft.Testing.Platform"}}`, references **`Microsoft.Testing.Extensions.CodeCoverage`** at **18.9.0 or later** in place of `coverlet.collector`, whose VSTest data collector MTP ignores without failing, and drops `xunit.runner.visualstudio`, the VSTest adapter MTP replaces. A repo whose test project is not yet MTP-based keeps the VSTest collector and its existing pin on the reusable validator, and that lagging state is a migration still owed rather than drift, until its own bump makes the project MTP-based and forces the move. The version floor is load-bearing rather than cautionary. Below 18.1.0 the extension is built against Microsoft.Testing.Platform 1.x, and an 18.0.x resolution, which is what a `>= 18.0.0` range picks, throws a `TypeLoadException` against the 2.x platform xunit.v3 4.0.0 carries, runs zero tests, and still writes a well-formed Cobertura file reporting full coverage, so only the non-zero exit says the run reported nothing. 18.9.0 is the first release on Microsoft.Testing.Platform 2.3.x, where every test project writes into the one shared `--results-directory` the invocation names rather than resolving that relative path per project. Two details of the invocation are equally load-bearing, and neither failure reds the job on its own. `--coverage-output` stays unset, because pinning one filename gives every test project in the solution the same path and a repo with more than one then keeps only whichever ran last. Leaving it unset produces the default name `<guid>.cobertura.xml`, which `codecov-cli`'s own file finder does not match. The validator therefore prefixes each report to `coverage-<guid>.cobertura.xml` before the upload step reads the directory. The Python invocation carries a load-bearing detail of its own, an omission rather than a collision: it names the report format and selects nothing to measure. `pytest-cov` reports on what `--cov` selects, so `--cov-report=xml` on its own measures nothing, writes no file, and exits zero, which the best-effort upload then reads exactly as it reads a healthy run. A Python repo with tests therefore references **`pytest-cov`** in its dev dependency group, selects the coverage source in its own `pyproject.toml`, an `addopts` entry of `--cov=<package>` in practice, and leaves the report at the repo root as `coverage.xml`, already the one path the upload step names. The validator **fails the test step when that file was not written**, since nothing downstream of it can tell an absent report from an uploaded one, so a repo that redirects the report through `[tool.coverage.xml]` reds the gate rather than uploading nothing from a green run. Where this guarantee does not apply (a `lint-only` profile for that type, per the hub's `registry/repos.json`), the hub's `spec/secrets.json` `typeMechanisms` mapping is not claimed for that repo, and the absence is not drift. The repo also ships a **`codecov.yml`** that sets the project and patch statuses to **`informational: true`** so a coverage delta never gates a PR (a distinct knob from `fail_ci_if_error`, which only guards the upload step), and excludes intentionally-untested, non-shipped code (an example/demo or benchmark project) from the coverage denominator via `ignore`. A repo may override this to enforce a coverage threshold where its quality bar requires it. Coverage output is a build artifact, so `.gitignore` excludes it (e.g. `coverage/`, `coverage.xml`, and `*.cobertura.xml`, with `.gitignore` the full source of truth) so a blanket `git add -A` won't stage the untracked output. *Prevents: coverage silently going unreported, a test project stranded on a runner the current SDK refuses, a stale and unused token, a coverage regression blocking an unrelated PR, and a coverage artifact committed by a blanket add.*

Measured at the time of that change, aiopurpleair and Financial-Modeling already carry both, homeassistant-purpleair and PlexCleaner carry no `uv.lock` so the step never runs there, and ESPHome-Config's Python is lint-only. The hub cannot smoke-test this itself, having no `tests/` and no `uv.lock` of its own.

🟢 Approval recommended

The validator change is correctly scoped to the intended Python profile and the documentation/spec updates consistently reflect and explain the new enforced coverage and recovery behavior.

Pull request overview

Updates the fleet CI contract and reusable validator to make Python coverage selection explicit (and enforced) and to document the correct recovery path when a registry push fails after the branch tip has moved.

Changes:

• Enforce that Python pytest --cov-report=xml runs actually produce a root coverage.xml by deleting any pre-existing file and failing the test step if none is written.
• Update WORKFLOW.md and the condensed D-guarantees to clarify (a) Python coverage requires a repo-provided --cov selector and (b) moved-tip push recovery uses Re-run all jobs rather than only re-dispatch.
• Align spec/project-types.json and the workflow adoption tracker notes with the new coverage contract.

Answering Qodo's summary-level finding, which carries no thread to resolve.

1. PR title exceeds limit — The PR title is 77 characters, exceeding the 72-character maximum. This violates both the dedicated length rule and the combined PR-title rule.

Confirmed and fixed. GOVERNANCE.md's "Pull Request Title and Commit Message Conventions" sets 72 characters or fewer for a PR title and a commit subject alike. The title now reads "Make the Python Coverage Selector Explicit and Name D4.5's Second Route", 71 characters.

Fixed on the title rather than by amending the commit subject, deliberately: the branch was already pushed and git-commit-conventions forbids force-pushing unconditionally, so the original 77-character subject cannot be rewritten. It never reaches develop either way, since this PR merges with --squash and GitHub takes the PR title as the squash commit's subject.

Also answering the other two findings from that round, for the record, since both have threads and both are disposed there:

• Coverage comments are overlong — declined on evidence. No comment-length rule is committed in this repository, and the nearest one that exists says the opposite. Detail in the thread.
• Adoption docs use change-framing — confirmed and fixed in 93813f8. comment-and-doc-style requires the present contract rather than a change from a prior state.

If cleanup leaves an artifact after a failed package push, Re-run all jobs reuses the same run and the duplicate upload can fail with 409, preventing the package push retry. Add overwrite: true to these serial uploads and regenerate the distributed copy.

Answering CodeRabbit's two outside-diff findings, which carry no threads to resolve.

1. Make package artifact uploads overwrite-safe for reruns — deferred, and independently confirmed

nuget-build-${{ inputs.branch }} and pypi-build-${{ inputs.branch }} use immutable upload-artifact uploads without overwrite. If cleanup leaves an artifact after a failed package push, Re-run all jobs reuses the same run and the duplicate upload can fail with 409, preventing the package push retry.

Correct, and already filed as #1216, which this independently corroborates. The mechanism matches what that issue records: the uploads are v7.0.1 with overwrite unset in all three build defaults, D5.3 leaves the cleanup best-effort so a failed delete is silent, and retention-days: 1 bounds the exposure to roughly the day in which an operator would actually reach for the recovery. #1216 also carries a second path this finding does not name, where a non-dispatch re-run skips the paired release-asset-* delete by design rather than through a failure.

Not fixed here for scope: adding overwrite: true changes publish behaviour, on a PR whose subject is D1.6's coverage selector and D4.5's recovery wording, in a repository that cannot smoke-test a publish path. #1216 also records that GitHub documents nothing about artifact visibility across run attempts, so whether the 409 actually occurs needs a live failed publish to settle, which is the maintainer's to run.

Worth noting the contract is coherent either way: D4.5 routes exactly the surviving-artifact case to --failed, so no recovery is lost. What #1216 would settle is whether the two routes are complementary or whether one is a superset.

2. Refresh the D4 pass record after the D4.5 edit — disproved

The current D4 digest is sha256:5603b025e2e0db0158efefabd074662b3a35a7ab2049a3d72fbe9b965e205ab3, not the recorded digest. The canonical-review check therefore treats D4 as stale and uncovered.

This does not reproduce. The engine is the authority on its own unit model, and run in this worktree it reports:

• canonical_review.py list gives the current D4 digest as sha256:2c8b0653258589c31a3f84491da60752deb95131bb5d2a2154a8465bacab69bf
• the recorded pass for that unit carries exactly sha256:2c8b0653..., stamped at merge base 16daf0dc
• canonical_review.py status reports stale: 0
• canonical_review.py check --target develop reports "All 3 changed carried unit(s) are covered by a recorded pass" and exits 0

The cited 5603b025... appears nowhere in reports/canonical-review.json and is not what the engine computes for that unit. The same gate runs in .husky/pre-push and in this repository's own validate action on every pull request, and both passed, so a genuinely uncovered unit would have blocked the push rather than reaching review.

No change made for this one.
