@coderabbitai Please suggest a fix for this issue and supply a prompt for an AI coding agent to enable it to apply the fix. Include the file and symbol names indicated in the issue at the head of your response. Ensure that this is validated against the current version of the codegraph. If further refinement to address this finding would be deleterious, please supply a clear explanatory one to two paragraph markdown message in a code block that I can paste into the CodeScene web ui's diagnostic suppression function so this diagnostic can be silenced. Deep, Nested Complexitytests/workflow_contracts/codescene_check_depth_test.py: _codescene_check_jobs What lead to degradation?_codescene_check_jobs has a nested complexity depth of 4, threshold = 4 Why does this problem occur?Deep nested logic means that you have control structures like if-statements or loops inside other control structures. Deep nested logic increases the cognitive load on the programmer reading the code. The human working memory has a maximum capacity of 3-4 items; beyond that threshold, we struggle with keeping things in our head. Consequently, deep nested logic has a strong correlation to defects and accounts for roughly 20% of all programming mistakes. How to fix it?Occassionally, it's possible to get rid of the nested logic by Replacing Conditionals with Guard Clauses. |

Record the approved-quality migration plan for retiring the redundant CodeScene pull-request submission path while preserving the ratcheted local gate and authoritative `main` upload.
Remove the artefact hand-off and privileged CodeScene submission workflow. Pull requests now enforce coverage only through the ratchet derived from main, while the main workflow remains the sole coverage publisher. Record the replacement architecture in ADR-024 and update workflow contracts and developer guidance to preserve the new boundary.
Record the successful quality gates and the delivery of draft pull request #724 so the living plan reflects the completed implementation.
Separate per-workflow validation from workflow-file enumeration so the coverage contract retains its behaviour with less nested complexity.
Describe the retained validators as standalone hostile-artifact inspection and remove references to the retired PR submission workflow from CLI help and test documentation.
The pull-request coverage boundary was pinned by two names: the `Upload PR coverage artefact` step and the `coverage-pr-submit.yml` file. A step or workflow that reached the same surface under any other name passed the contract, so the prohibition held only for the spellings this repository happened to use. Detect the surface instead. A pull-request-triggered workflow now fails if any step publishes the coverage report through `actions/upload-artifact`, invokes the CodeScene coverage action, or references `CS_ACCESS_TOKEN` in its parsed values or its raw text; a `workflow_run` consumer is held to the same rule under any file name. The publisher detector reads the action and the artefact path rather than a step name, and treats a publish step that names no path as a violation, because that uploads the workspace holding the report. A detector that stopped matching would make the repository assertion pass by finding nothing, so the same module drives the detectors against synthetic workflow text: a renamed publisher, a renamed CodeScene invocation, and a credential reference in parsed values and in raw text must each be reported, and a workflow inside the boundary must produce no offender. The CodeScene check-mode contract selects its workflows through the shared `all_workflow_documents` reader and `WORKFLOWS_DIRECTORY` rather than re-deriving both, which also removes the nested glob that the code-health rule flagged. Validated with `make test-workflow-contracts` (533 passed, 2 skipped). Each detector was separately proved to fire by injecting a renamed publisher, a raw-text credential, and a resurrected `workflow_run` consumer.
`origin/main` advanced to c32efb8 while this branch was under review and landed its own ADR-024 for recursive workspace search. This branch had claimed the same number, so the rebase produced a contents index with two ADR-024 entries. Renumber this branch's record to ADR-025 everywhere it is referenced rather than leaving the collision in the index. ADR-022's status line changed from `Accepted` to `Superseded` without a record of why, which reads as a retroactive edit to a decision that was accepted and acted on. Add a dated addendum stating the supersession, the limitation that forced it — the trusted consumer ran outside pull-request context and so reported on the wrong commit — what is retired, and what survives. ADR-025 claimed that pull-request CI "does not upload the report as a GitHub artefact". The pinned `generate-coverage` revision archives the report under an unconditional `Archive coverage` step with no opt-out, so the claim was false. State what is actually true: the pull-request job adds no publication step of its own, and the residual artefact is the shared action's. Record it as a known residual and say why no repository contract can observe it. Bring the ExecPlan's context, focused-evidence, and outcomes text in line with the repository as it stands, and add the completion revision entry with the final validation evidence.
The publication-surface prong examined workflows declaring `pull_request` only. `pull_request_target` is the variant that runs in the base repository's context and can therefore read its secrets, so a coverage step there is the more serious form of the same violation, not an unrelated one. A workflow using it — `dependabot-automerge.yml` in this repository — escaped the prong entirely. Both triggers are now read. The prong also asserts that at least one such workflow was read, so the trigger cannot fall out of the reader's reach without failing the test, and a new test drives `declares_trigger` over both trigger names in the scalar, sequence, and mapping spellings parsed from real YAML. That test also pins the near miss: `pull_request` is a prefix of `pull_request_target`, so a substring comparison would accept one for the other. Fixing the two detectors to use match statements resolves the structural pattern-matching finding, and the offender-free assertion now carries a failure message. Proved by injecting a credential reference into the existing `pull_request_target` workflow: the prong reports it by raw text and by parsed value, and the workflow was restored afterwards. Validated with `make test-workflow-contracts` (534 passed, 2 skipped) and the df12 Python lint suite at 10.00/10.
The pull_request_target prong grew `ci_coverage_wiring_test` past the 400-line module cap the lint gate enforces, so the pure predicates and their constants move to `ci_coverage_wiring_invariants`, leaving the contract assertions in the test module. This mirrors the existing split between `codescene_check_depth_invariants` and its test. No assertion changes. The synthetic workflows now interpolate their action names and report path from the constants they are checking rather than restating them, so a renamed constant cannot leave a fixture pinned to the old spelling.

Sorry, something went wrong.
The pull-request lane generated the report but could not withhold it: the shared `generate-coverage` action archived the report under a step of its own, and that step ran unconditionally. Declining the archive is the only way this repository can keep the report local, because a step the action declares is not one any scanner over this repository's steps can see. The opt-out was added to the action in leynos/shared-actions#505 and is carried by the merged revision a5765019. Both callers move to it, so the two lanes cannot drift onto different behaviour, and the pull-request lane passes `publish-artefact: 'false'`. The trunk lane leaves the input unset, keeping the default that archives the report CodeScene reads; setting it there would leave CodeScene with nothing. Both directions are asserted rather than trusted. `coverage_surface_offenders` fails any coverage call that omits the opt-out or supplies a value the action does not compare against, and a further test holds the lanes apart. The detector is driven against synthetic workflow text, including a workflow whose first coverage call opts out and whose second does not, so a detector that read the workflow as a whole rather than per step would fail rather than pass by finding nothing.
…efact ADR-025, the developer guide, and the ExecPlan all stated that the pinned action archived the report unconditionally, that no repository contract could observe the step, and that removing it would need an input the action did not offer. Each of those statements was true of the revision then pinned and is false of the one now pinned, so leaving them would have documented a boundary weaker than the one the tests enforce. The ExecPlan carries the supersession as a dated revision note, so a reader can see that the earlier text was correct when written rather than merely wrong. The plan's trace links, its ARCH-PR-LOCAL obligation, and the developer guide's contract paragraph now name the opt-out the pull-request lane passes and the prohibition on the trunk lane setting it.

Summary
from
main;workflow_runsubmission, andthe custom CodeScene Check Run machinery;
at all, through the
publish-artefactopt-out added inleynos/shared-actions#505;
coverage-main.ymlas the sole ratchet-baseline writer and CodeScenecoverage uploader; and
ADR-025
and updates the
developer guidance.
The active
main-required-checksruleset does not require the retired customcheck — its required contexts are
build-test,kani-smoke,netsukefile,and
release / metadata— so this change needs no GitHub ruleset update.CodeScene's daily analysis schedule and unavailable-data display policy remain
project settings.
The pull-request lane now passes
publish-artefact: 'false'to the sharedgenerate-coverageaction, which suppresses the action's ownArchive coveragestep, so no report is archived on a pull request at all. That inputwas added to the action in
leynos/shared-actions#505
and both netsuke callers are re-pinned to the merged revision
a5765019912a8ab6882b12db049c7cde635f3a85. The trunk lane leaves the inputunset, so its archive and the upload CodeScene reads continue as before.

file names: every pull-request-triggered workflow (both
pull_requestandpull_request_target, in each spellingon:accepts) and anyworkflow_runconsumer under any file name is rejected if it publishes coverage through
actions/upload-artifact, invokes the CodeScene coverage action, or referencesCS_ACCESS_TOKENin its parsed values or its raw text. Each detector is alsodriven against synthetic workflow text, so a detector that stopped matching
fails the suite instead of passing it by finding nothing.
The action's archive step belongs to the action rather than to this repository,
so no scan of this repository's steps can see it. The contract observes it the
only way it can: a detector fails any coverage call that omits the opt-out or
supplies a value the action does not compare against, and a further test holds
the two lanes apart, requiring the pull-request lane to decline the archive and
forbidding the trunk lane from passing the input. No credential crosses that
boundary, and the pull-request report never leaves the runner.
The implementation follows the
ExecPlan.
