-
Explanation
Docstring coverage is 100.00% which is sufficient. The required threshold is 80.00%. Docstring coverage is scoped to functions touched by this diff. Analyzed 42 functions across 5 files. (6 skipped: 6 unsupported.)
Full details: Testing (Overall)
-
Explanation
The workflow contracts are substantive. They inspect every carrying job from the five instrumented workflows, enforce the telemetry pair and unconditional finish, and validate the actual sccache wiring (
tests/workflow_contracts/ci_telemetry_test.py:48-109;sccache_test.py:344-372). The pure contract tests reject missing or misplaced telemetry, a report before the build, incorrect cache inputs, and manual statistics reporting (ci_telemetry_test.py:162-204). Roll-up tests reject action steps, no-op steps, missingneedsaggregation, and telemetry exemptions (_telemetry.py:165-183;ci_telemetry_test.py:212-243). Prior failure addressed: Current tests reject telemetry actions and no-op roll-ups, and require needs-based aggregation. The sccache contract requires the report after setup and directly before telemetry finish; the report-before-build mutation is covered in ci_telemetry_test.py:171-204.
Full details: User-Facing Documentation
-
Explanation
Pass this check. The pull request changes CI instrumentation and developer-facing workflow guidance, not Axinite runtime behaviour or an end-user interface. The only documentation change is
docs/developers-guide.md, which documents the shared telemetry actions and CI runner sizing. No update todocs/users-guide.mdor migration guidance is required.
Full details: Developer Documentation
-
Explanation
The developer guide now documents the shared telemetry actions, both valid start-order forms, unconditional finish behaviour, roll-up exemptions, telemetry outputs, and sccache wiring at docs/developers-guide.md:243-261. The workflows match this description: compile-contract, audit, Windows, and version-check jobs start telemetry before checkout, while other jobs place checkout or disk clean-up first (for example coverage.yml:94-96 and test.yml:61-64). Prior failure addressed: docs/developers-guide.md:246-249 now states that checkout and disk clean-up may precede telemetry and identifies the small pre-checkout job group; the affected workflows implement that ordering.
Full details: Module-Level Documentation
-
Explanation
Pass the module-level documentation check. The pull request adds module docstrings to
tests/workflow_contracts/_telemetry.py(lines 1-9) andtests/workflow_contracts/ci_telemetry_test.py(lines 1-21). These docstrings state each module's purpose, utility and relationship to the workflow contracts and collector. The modified modulescodescene_coverage_test.py(lines 1-11),runner_sizing_test.py(lines 1-22) andsccache_test.py(lines 1-18) also retain clear module docstrings describing their purpose and use.
Full details: Testing (Compile-Time / Ui)
-
Explanation
Pass this check. The pull request changes YAML, Python, Markdown and shell files only; it adds no Rust or TypeScript compile-time behaviour, so trybuild or an equivalent compile-time test is not applicable. The workflow changes are structured configuration, not generated or user-facing UI output. The added contract tests use focused semantic assertions for action pinning, ordering, conditions, sccache wiring and roll-up variants, including deliberately invalid arrangements (
tests/workflow_contracts/ci_telemetry_test.py:80-243andtests/workflow_contracts/_telemetry.py:93-183). A broad snapshot of workflow files would add brittleness without improving coverage.
Full details: Unit Architecture
-
Explanation
Mark this check PASS. The new telemetry checks are pure functions over in-memory step mappings:
_telemetry.py:48-183performs only mapping reads and returns findings. The mutation tests use copied in-memory fixtures inci_telemetry_test.py:135-204. Keep workflow side-effects explicit through named, full-SHA-pinned actions and explicitwithinputs; the PR removes the hidden inline sampler and manual sccache reporting. Repository reads remain at the existing_workflow_files.jobs()boundary, which documentsSourceReadErrorhandling. No changed unit combines unrelated persistence, transport, formatting, or orchestration responsibilities.
Full details: Domain Architecture
-
Explanation
Pass the Domain Architecture check. The PR changes only CI workflows, CI contract tests, CI documentation, and the CI resource-sampler script. It changes no application, domain, persistence, transport, or adapter source. The new telemetry helper contains pure checks over workflow step mappings and calls pinned shared-actions from workflow boundaries; it does not introduce domain logic or infrastructure dependencies into the domain model.
Full details: Observability
-
Explanation
The pull request adds suitable observability for the changed CI behaviour. All five target workflows use paired shared telemetry actions, and finish steps run with
if: always(); sccache jobs also report status and backend through the pinnedsccache-reportaction (for example,.github/workflows/coverage.yml:161-221andtest.yml:248-257). The workflow contracts enforce pairing, failure-safe reporting, sccache wiring, full-SHA pinning and roll-up coverage (tests/workflow_contracts/_telemetry.py:93-162;ci_telemetry_test.py:72-109). The pinned shared-actions commit emits oneDF12_CI_TELEMETRYrecord plus a summary (leynos/shared-actions@81374b6f183e59f0570ad36217ded90d3240fda6,.github/actions/ci-telemetry-finish/action.yml:4; README search evidence at line 4). The record includes runner, job, run, timing, CPU, memory, disk and bounded sccache fields, while sccache outcomes and elapsed time use bounded metric values (.github/actions/ci-telemetry-finish/README.md:48,86;.github/actions/sccache-report/action.yml:79,109,123). This provides diagnosis for failures, resource pressure, cache fallback and cache errors without adding secrets, raw customer data, unbounded labels, or an unobserved production service boundary.
-
Full details: Testing (Unit And Behavioural)
-
Explanation
The pull request still lacks a workflow-boundary integration test. The added tests are static contract tests:
ci_telemetry_test.pystates that its checks are pure functions over step mappings (lines 16-18), reads parsed jobs (lines 48-91), and mutates synthetic step lists (lines 135-204).make test-workflow-contractsonly runs this PyYAML/Pytest contract suite (Makefile lines 192-193). The changed workflow files do invoke the pinned actions, but no changed test runs a GitHub Actions job, executes the telemetry or sccache actions, forces a job failure, or checks the emitted record and cache fields. The PR therefore verifies configuration shape, not the externally observable workflow behaviour required by this check.Resolution
Add a GitHub Actions boundary integration or end-to-end test for a representative Linux job. Run the pinned
ci-telemetry-start,sccache-report, andci-telemetry-finishactions, force the job work to fail, and assert that the finish step still emits exactly one telemetry record with the expected sampler and sccache fields. Retain the existing static workflow-contract tests.
Full details: Testing (Property / Proof)
-
Explanation
The new telemetry contract introduces invariants over arbitrary step sequences, counts, placements and orderings in
tests/workflow_contracts/_telemetry.py:62-183. The tests cover only fixed mutations intests/workflow_contracts/ci_telemetry_test.py:162-240; they do not use Hypothesis or another property/proof tool. The repository already provisions Hypothesis for this test target inMakefile:192-193. This meets the check condition for a property test.Resolution
Add Hypothesis property tests for
telemetry_problems,sccache_problemsandroll_up_problems. Generate bounded step lists and relevant permutations, assert valid generated arrangements are accepted, and assert mutations such as duplicate actions, misplaced reporting, missingalways(), invalid cache wiring and non-roll-up bodies are rejected. Keep the existing parameterized examples as readable regression cases. No exhaustive proof is required.

Review comments at @tests/workflow_contracts/ci_telemetry_test.py:
- Around line 56-77: Add a single-line summary docstring to each private helper:
_instrumented, _carrying, _ids, _steps and _uses. Keep each docstring focused on
that helper’s purpose.
- Line 153: In the step iteration, remove the unjustified type-ignore and
iterate over the typed `job.steps` property instead of reading `job.body`
directly; this also ensures non-mapping entries are filtered before `_uses`
processes them.
- Around line 82-83: Add clear failure messages to the bare assertions in the
telemetry contract tests, including the selector count, pin set, sccache-report
id, and sampler-script path; each message should identify the job or check and
its expected value. Replace the `ids` lambda with `ids=str` to satisfy Ruff’s
PLW0108 rule.
- Around line 129-130: In the test using `_steps(job)`, select setup-rust calls
by their `_uses(s)` action reference and skip only when no such calls exist.
Then assert that exactly one matching call has the required `setup-rust` id, so
a missing or incorrect id fails the test rather than skipping it.
Review comments at @tests/workflow_contracts/runner_sizing_test.py:
- Around line 13-14: Add a test alongside the existing `_sized_jobs()` contract
checks that asserts every sized job belongs to a workflow in
`INSTRUMENTED_WORKFLOWS`, importing that set from `ci_telemetry_test.py` or
moving it to `_workflow_policy.py` if needed. Update the stale sampler wording
in `_sized_jobs()` to refer to telemetry.
Review comments at @tests/workflow_contracts/sccache_test.py:

@coderabbitai At head 15d9c62, please re-check the five rows in your walkthrough for 76e200a (two failed, three warnings) and the six threads, addressed in the later commits:
Threads: private helper docstrings, assertion messages and ids=str, setup-rust selected by action reference with the id asserted apart, the type-ignore removed, the sized-job link, and the status assertion message. Do these clear the five rows and the six threads, and is anything else blocking a merge at this head? |

Replace the inline resource sampler and the hand-written sccache report with ci-telemetry-start, ci-telemetry-finish and sccache-report from shared-actions, pinned to 81374b6f. Every job in the five instrumented workflows now prints one telemetry record, except four roll-ups that run one step over needs. Delete scripts/ci-resource-sampler.sh and move the contracts from the sampler to the actions.

Part of DF12-98
Summary
code_style.yml,coverage.yml,codescene-coverage.yml,e2e.ymlandtest.ymlnow startsci-telemetry-startearly and ends its work withci-telemetry-finishunderif: always(), so the central CI observability collector (https://github.com/leynos/grafana/pull/12) can read one runner record per job. The four roll-ups that run one step overneedscarry no pair. The Windows jobs carry it too (their record saysunsupported-os).scripts/ci-resource-sampler.sh(the sampler the actions were generalized from) and the hand-written sccache report with shared-actions'ci-telemetry-start,ci-telemetry-finishandsccache-report, all pinned to leynos/shared-actions@81374b6 (Add the ci-telemetry start and finish actions (2.1.1) shared-actions#634, Capture normalized sccache statistics in the telemetry record (2.2.1) shared-actions#636). The record gains the busy cores, and an sccache fallback stands down instead of publishing a table of zeros.tests/workflow_contracts/ci_telemetry_test.pyand_telemetry.pyhold the contract as pure checks over a job's steps, with deliberately wrong arrangements the checks must refuse. The sampler contract inrunner_sizing_test.pyis replaced by it, and a new test ties every sized (paid-shape) job to a workflow that carries telemetry.Change Type
Linked Issue
None in this repository. Workstream: DF12-98 (CI observability, grafana), plan step 2.3.1.
Validation
cargo fmt,cargo clippy: not applicable, no Rust changed.make test-workflow-contracts: 1,483 passed. Sixcompile_contract_group_testcases fail on this host because cargo-nextest here is 0.9.116 and CI pins 0.9.140 (the same six fail without this change); CI is the gate for them.actionlinton the five workflows,make check-fmt,make spellingandmake markdownlintpass.Security Impact
None. The three actions are first-party and pinned to a full commit; the finish action reads only named
GITHUB_*andRUNNER_*variables and no secret, and neither the sampler nor the report needs a token or new permissions. No workflow permissions, triggers, secrets or network destinations change.Database Impact
None.
Blast Radius
CI only: the five workflows' jobs and the workflow contracts. The actions never fail a job (without Python they warn and exit 0), so a fault in telemetry cannot turn a green job red. The sampler wakes every ten seconds, which is negligible against a compile and which
docs/developers-guide.mdsays not to put on a timing job.Rollback Plan
Revert the commit. It restores
scripts/ci-resource-sampler.sh, the inline sccache report and the old contract in one step; nothing outside the repository is written, and the collector reads a job without a record asabsentuntil it is reinstated.Overlapping open pull requests
None is touched. Robot-house: #438, #275. Fleet: #427, #402. User: #365. Dependabot: #429, #425, #424, #423, #422. The one that matters:
Dependency Audit(and theRun Testsroll-up that needs it) fails on 25 RustSec advisories (among them RUSTSEC-2026-0339 and RUSTSEC-2026-0342 in quinn-proto 0.11.14) in the dependency tree, which this pull request does not touch (no manifest or lock file changes); #438 patches runtime dependencies.Review track: C (CI)
