ci: exempt generated API reference pages from codeowner review#13551dagil-nvidia wants to merge 2 commits into
Conversation
The Python/Rust API reference pages under docs/fern/pages/reference/api/ are deterministic outputs of gen_python_api.py / gen_rust_api.py, and the pre-merge freshness gate (--check) already blocks both stale copies and hand edits. Owning them under /docs/ meant every source PR that touched a documented symbol had to carry the regenerated page and wait on docs codeowner review for a diff no human authored -- an extra required reviewer with nothing to scrutinize. Add an 'unowned:' section to the areas.yaml schema: globs emitted last with no owner (GitHub's ownerless-pattern semantics), so matching files need no codeowner review while everything else under docs/ -- including the generators and the hand-written API landing page -- stays docs-owned. The coverage gate counts unowned globs as claimed, declaring a glob both shared and unowned is rejected, and parse_codeowners now retains ownerless rules so who_owns resolves them correctly.

Reject a scalar unowned value.
Line 391 accepts a YAML string because the code iterates before it validates the container type. For unowned: docs/..., Line 397 creates character-level ownerless rules. Require a list before iterating. Add a regression test for scalar input.

Compare canonical globs for conflicts.
anchor() makes docs/path/ and /docs/path/ the same emitted rule. Lines 398-405 compare raw strings, so this configuration is accepted. The final ownerless rule then removes the shared owners. Canonicalize before deduplication and conflict detection. Add coverage for both spellings.

🟡 Safety check that stops an exemption from silently removing reviewers can be bypassed by writing the path slightly differently
The check that rejects a path listed both as shared and as review-exempt compares the two spellings literally (shared_globs & set(unowned) at .github/codeowners/codeowners_match.py:398-405) before either is normalized, so the same directory written with and without a leading slash slips through and the exemption silently removes the shared reviewers.
Impact: A directory intended to require multi-team review can end up requiring no review at all, with no error reported.
Anchoring happens after the conflict check, so equivalent globs compare unequal
Both sections are anchored at use time: anchor(s["glob"]) for shared (.github/codeowners/emit_codeowners.py:255) and anchor(g) for unowned (.github/codeowners/emit_codeowners.py:360, .github/codeowners/codeowners_match.py:145). So shared: [{glob: "/docs/x/"}] plus unowned: ["docs/x/"] resolve to the identical emitted pattern /docs/x/, yet the conflict set intersection sees two different strings and passes. The unowned line is emitted last, so last-match-wins strips the shared owners — precisely the outcome the guard's error message says it prevents.
Relatedly, the validation at .github/codeowners/codeowners_match.py:392-397 only checks that entries are non-empty after strip() but stores them unstripped, so " docs/x/" is accepted and anchored into / docs/x/, a pattern that matches nothing (reported only as a non-blocking "dead glob" by build_codeowners.py:128).

🔍 Kubernetes API reference output is equally generated but not exempted
The same rationale applies to gen_kubernetes_api.py, whose deterministic output lives at docs/fern/pages/reference/kubernetes-api/full-api-reference.mdx and is guarded by the same --check gate (.github/workflows/pre-merge.yml:168), yet it is not listed under unowned:. Worth confirming the omission is deliberate scoping rather than an oversight, since PRs touching operator CRDs will still pull in docs codeowner review for a machine-generated diff.

These directory-wide exemptions also match files the freshness gates never validate. For example, a PR can add docs/fern/pages/reference/api/python/custom.txt or any extra file under the Rust directory; the Python generator only checks expected outputs and orphaned *.mdx files, while the Rust generator checks only README.mdx, so CI passes and the new file receives no codeowner review. Narrow these patterns to the actual generated files (Python *.mdx and Rust README.mdx) or make the generators reject every unexpected file in the exempt directories, then regenerate CODEOWNERS.

If a future edit uses the natural but invalid scalar spelling unowned: docs/generated/ instead of a YAML list, this loop accepts every character as a valid string and emits ownerless rules such as /d, /o, and /s rather than rejecting the policy. Both regeneration and the drift check consume the same malformed model, while dead globs are only warnings, so CI can pass even though the intended exemption is silently ineffective. Validate that the top-level value is a list before validating its entries.

The conflict check compares raw strings even though emission normalizes both through anchor(). Thus shared: [{glob: docs/generated/, ...}] together with unowned: [/docs/generated/] bypasses this guard, but both render as /docs/generated/; because the ownerless rule is emitted last, it silently removes the shared owners the validation is meant to protect. Compare anchored forms (and reject anchored duplicates) before generating CODEOWNERS.

Review findings: reject a scalar 'unowned:' value (a string would iterate per-character and emit ownerless /d /o /c /s rules); compare shared vs unowned conflicts on anchored globs so docs/x/ and /docs/x/ collide; and scope the exemption to python/*.mdx + rust/README.mdx so a non-generated file smuggled into the exempt directories still requires docs review.

Overview
Source PRs that touch a documented Python/Rust symbol must carry the regenerated API reference page (the pre-merge freshness gate requires it), and because those pages live under
/docs/, the regeneration alone pulls in docs codeowner review. Example: #13487 changes onlycomponents/src/dynamo/frontend/code + tests, yet waits on docs review for a machine-generatedfrontend.mdxdiff no human authored.The generated pages are deterministic outputs of
gen_python_api.py/gen_rust_api.py, and CI already guards their integrity in both directions: a stale copy fails--check, and so does a hand edit. A required human sign-off on that artifact adds a reviewer without adding scrutiny.What changed
