CI configuration nothing scans is declared, not left out of the scanner list - #157

Conversation
…er list `uphold supply-chain` runs five scanners, and between them they cover manifests, locks and GitHub Actions workflows. A `.circleci/config.yml` is read by none of them -- zizmor, the one shaped for the job, parses Actions only -- and nothing in the output said so. Five green sections over a repository whose pipeline definition no scanner opened read exactly like six. So the run says it. Where a range or a tree holds CI configuration this set does not read, the zizmor section names each file first: it is the section whose edge the gap is. It is a statement and not a verdict -- neither count moves and the exit code does not change, because nothing failed and nothing was prevented from looking; the tools carried here do not cover the file, which was true before the run started. `interesting()` now admits those paths, precisely BECAUSE nothing scans them: a push carrying one CircleCI edit would otherwise leave an empty range and be told there was nothing here a scanner reads. No section is handed the file -- each selects its own inputs by name or by `is_workflow` -- so zizmor is never given something it cannot parse. Not filled with checkov, which is the only scanner found that reads a CircleCI config. It logs a YAML parse error at debug level, returns no model and exits 0, so a config it could not read is indistinguishable from a clean one. That is this command's third verdict imported as a silent pass, which is the defect the crate exists to refuse. It is named in the module header and in REFERENCE, and not run. Closes #153.

📝 WalkthroughWalkthroughThe supply-chain command now identifies unsupported CI configuration, reports declared unscanned gaps, and preserves scanner counts and exit status. Tests cover path detection, tree enumeration, scoped changes, whole-tree scans, and unreadable directories. ChangesUnscanned CI reporting
Estimated code review effort: 3 (Moderate) | ~20 minutes Severity of issue fixed: Medium Merge Risk: 🔵 Low · up to This change reports unsupported CI configuration without altering scanner inputs or exit semantics, but the new reference documentation contains a fenced block that needs a language identifier to avoid lint failure.

The declaration was general in code and CircleCI-shaped in prose: eleven mentions of one vendor for a rule that covers every CI system except GitHub Actions. A reader would take CircleCI for a special case and the mechanism for a patch aimed at it. So the prose is written at the class, and the asymmetry that does exist is named rather than left to be inferred. GitHub Actions is not the CI system this crate favours; it is the CI system somebody wrote a scanner for. A job that mints a token, pulls an unpinned action or orb, or runs a command over untrusted input is the same defect whichever vendor's file it lives in. What separates the vendors here is that exactly one of them has a scanner worth running, and the rest are enumerated by name because their file names are what identifies them. CircleCI survives in the three places where it is evidence rather than example: checkov's fail-open parser is a CircleCI parser, and its check set is a CircleCI check set. Naming another vendor there would be a claim nobody tested. The whole-tree CLI test now plants a `.gitlab-ci.yml` where it planted a `.circleci/config.yml`. Two tests over one vendor left every other name in the list resting on the unit test alone. Claude-Session: https://claude.ai/code/session_01Vxjh3qKGTu2jqqnakw87qd
The prose said each thing about three times: the asymmetry in the module header and again in REFERENCE and again in a const, the "five green sections read like six" line in a function doc and in REFERENCE, and every test doc restating the argument the code above it already carries. Nothing is dropped that a reader needs -- the gap, the fail-open evidence for checkov, why `interesting()` admits paths nothing scans, and why the list is a list rather than `*.yml` all survive. 133 lines of documentation become 81.

MD040 on the block added in this branch: the run's output was fenced with no language, where the seven other output blocks in REFERENCE carry `text`. Claude-Session: https://claude.ai/code/session_01Vxjh3qKGTu2jqqnakw87qd

Closes #153, along the line the issue's own survey landed on: record the surface as unscanned, do not wrap checkov.
What the run now says
Said in the zizmor section because that is the section whose edge it is: zizmor is the workflow-security scanner, and the boundary of what it parses is the boundary of what the whole set covers. Printed before that section's early returns, so a missing zizmor and a repository with no Actions workflow still get the declaration.
A statement, not a verdict. Neither
failednorunreadmoves and the exit code does not change. Nothing failed and nothing was prevented from looking; the tools this command carries do not cover the file, which was already true before the run started. A.circleci/directory must not turn every push into exit 2 forever.Why checkov is named and not run
The issue's survey, in code form. checkov is the only scanner found that reads a CircleCI config, and it fails open: a YAML parse error is logged at debug level, the parser returns no model, and the run exits 0 with
"parsing_errors": 0. A config it could not read is indistinguishable from a clean one -- this command's third verdict imported as a silent pass, which is the defect the crate exists to refuse. It is cited in the module header and indocs/REFERENCE.md, with the thin check set and the misspelled@volitileorb tag, so the next reader does not re-survey the field.The one behaviour change outside the print
interesting()(src/supply.rs) now admits these paths -- precisely BECAUSE nothing scans them. A push changing only a.circleci/config.ymlwould otherwise leave an empty range and be told "nothing in this range that a scanner reads", which is true of that file in a way the sentence does not mean. Nothing downstream is handed it: every section selects its own inputs by name or byis_workflow, so zizmor is never given a file it cannot parse. The issue's warning aboutis_workflowandfind_workflow_dirsnaming zizmor's input domain still holds -- neither is touched.The surface: anything under a
.circleci/directory at any depth, plus.gitlab-ci.yml,.gitlab-ci.yaml,azure-pipelines.ymlandJenkinsfileby name. A list rather than a pattern, because*.ymlat a repository root is a config file for anything.Tests
