Fixes #3568

Related: #3534 (introduced the Decision/Question prefix change), #3549 (label reconciliation), #3564 (label preservation). The locked-config portability risk stays tracked in GIT-2341.

Context

  • Severity/Impact: Medium. Both defects produce wrong values silently, with no error. Runtime impact is currently dormant because both scripts are referenced only from archived/ workflows, but both are shipped, tested and documented, so the wrong behaviour returns the moment either workflow is reactivated.
  • Affected versions/environments: scripts/agents/includes/derive-project-fields.cjs and scripts/automation/normalize-issue-pr-titles.cjs on develop since the issue-type consolidation in chore: label-consolidation - Align Decision taxonomy and templates #3534. scripts/automation/normalize-issue-pr-titles.js is unaffected.

Reproduction

  • Steps:
    1. Call inferTypeFromContext() with a title or body containing documentation, integration, compatibility, interop or dependency, or a docs/-prefixed headRef, passing the real project_field_mappings from .github/issue-fields.yml.
    2. Call isAlreadyPrefixed("decision:Adopt GraphQL") and isAlreadyPrefixed("question:How do we sync") on the CommonJS normaliser.
  • Expected vs Actual: expected Documentation, Compatibility or Dependency Update, and false respectively. Actual: every type resolved to the generic default (Chore for pull requests, Task for issues), and both prefix checks returned true, so normalizeTitle returned null and left the malformed title untouched.

Root Cause

  1. derive-project-fields.cjs inferred type:documentation and type:integration. Neither label exists in project_field_mappings.Type after the consolidation, so mappings.Type[rule.label] was undefined. inferMappedValueFromText returned that empty string on the first pattern match — discarding the match instead of continuing — and deriveProjectFieldValues then applied the generic default. Confirmed against .github/labels.yml, where both retired labels are absent and type:docs, type:compat and type:dependency are present.
  2. normalize-issue-pr-titles.cjs used \s* after the colon where its .js twin uses \s+. The divergence predates chore: label-consolidation - Align Decision taxonomy and templates #3534, which only appended |decision|question to both copies. scripts/automation/__tests__/normalize-titles.test.js requires the extensionless path, which resolves to the .js file, so the CommonJS copy had no coverage at all.
  3. The existing field-parity.test.js guards emitted values against the declared option sets. It never checked the rule labels, so a rule pointing at a non-existent label passed CI while producing the wrong value.

Fix Summary

  • derive-project-fields.cjs: docs/ and doc/ prefixes and the documentation keyword rule now map to type:docs; the retired integration rule is split into type:compat (integration, compatibility, compat, interop, interoperability) and type:dependency, because the config exposes two distinct canonical values for that keyword group. inferMappedValueFromText now keeps scanning when a matched rule has no configured mapping, so an unmapped label cannot swallow a later matching rule. The rule tables are exported for the parity suite. Behaviour is unchanged whenever every rule label is configured, which the new test asserts.
  • normalize-issue-pr-titles.cjs: the prefix pattern now requires whitespace after the colon, making the two shipped files byte-identical.
  • No locked governance file is modified. The .cjs/.js duplicate is deliberately not consolidated here — deleting a shipped file is a separate decision.

Verification

  • Tests added/updated to cover the bug
  • Manual verification steps (browsers/devices) — N/A, no UI; behaviour verified by executing the functions directly and through the CLI path
  • Negative/edge cases checked

Evidence:

  • Full suite: 280 suites / 5644 tests passed (baseline 5573; +71 new tests).
  • Both new suites were proven to fail against the unfixed source: 20 failures across the two field suites and 10 failures in the normaliser parity suite when the fix is reverted with the tests kept, all passing once restored.
  • npm run validate:issue-fields: pass.
  • Changelog gate: node .github/validation/changelog/bin/validate.js --trigger pr_submission reports 10 failing entries, identical to the pre-change baseline, with 0 new failures introduced.
  • markdownlint-cli2 CHANGELOG.md: 0 issues. actionlint: not applicable, no workflow files changed.
  • eslint on the changed test files: 0 errors. All 508 warnings are prettier/prettier, the pre-existing repo-wide quote-style mismatch (424 on the untouched files); the new code follows the committed double-quote style of the surrounding files.
  • semgrep scan --config p/security-audit --config p/secrets --config p/php: 0 findings across the 5 changed files.
  • Qodo review of the branch against develop (full depth, coverage complete): 0 findings.

Risk & Rollback

  • Risk level: Low. Rule ordering is preserved — the two replacement rules occupy the position of the single rule they replace, so precedence between pre-existing rules is unchanged. Explicit labels still take precedence over content and branch inference, so labelled items are unaffected. A text matching both dependency and a later rule now resolves to Dependency Update rather than an empty value; previously it silently produced the generic default. The CommonJS normaliser is now stricter, so a bare decision: title gains a prefix, matching the .js implementation and the behaviour the existing feat:/fix: tests already assert. Exported symbols are additive.
  • Rollback plan: revert the single commit. No configuration, schema, API or persisted-data change is involved, so there is nothing to migrate back.

Changelog

Added under ## [Unreleased] → ### Fixed in CHANGELOG.md:

Issue-Type Inference Corrected — Documentation, integration and compatibility content now lands on its correct issue type instead of a generic default. (#3568)

Follow-up (not in this PR)

  • docs/ISSUE_TYPES.md, docs/ISSUE_TRIAGE_LABELING.md, docs/LABELING_FAQ.md, docs/PR_GOVERNANCE.md and others still document the retired type:documentation and type:integration labels. That documentation-vocabulary sweep is well outside this issue's runtime scope.
  • normalize-issue-pr-titles.cjs and .js are byte-identical duplicates; consolidating to one file would remove the drift risk at source.
  • .gitignore lists node_modules/ with a trailing slash, which does not match a node_modules symlink — that is how the symlink in ci(mergify): keep stale pull requests current with develop #3563 reached the repository.

Summary by CodeRabbit

  • Bug Fixes
    • Documentation, dependency, integration, and compatibility content now receives more accurate issue types.
    • Titles with a recognized prefix but no text after the colon are now normalized consistently.

…ion (#3568)

Project field inference referenced type:documentation and type:integration,
neither of which exists in project_field_mappings.Type after the issue-type
consolidation. The lookups returned an empty string, so documentation,
integration, compatibility, interoperability and dependency content was
discarded and silently fell through to the generic default type.

Map those rules to the canonical labels instead: type:docs for the docs/
branch prefixes and documentation keywords, and split the retired integration
rule into type:compat and type:dependency. inferMappedValueFromText now keeps
scanning when a matched rule has no configured mapping, so an unmapped label
can no longer swallow a later matching rule.

normalize-issue-pr-titles.cjs used \s* after the colon where the JavaScript
implementation uses \s+, so it treated bare "decision:" and "question:" titles
as already prefixed and left them malformed. The two files are now identical.

Extend the field-parity suite to assert every inference rule label is
configured, and add a parity suite that exercises the CommonJS and JavaScript
normalisers side by side; both suites fail against the previous code.

📝 Walkthrough

Walkthrough

The pull request updates issue-type inference to use configured canonical types and changes the CommonJS title normalizer to require whitespace after recognized prefixes. Tests cover inference rules, mapping parity, and title-normalizer parity.

Changes

Project-field type inference

Layer / File(s) Summary
Canonical type inference and regression coverage
scripts/agents/includes/derive-project-fields.cjs, scripts/agents/includes/__tests__/*, CHANGELOG.md
Documentation branch prefixes and keywords map to type:docs; dependency keywords map to type:dependency; integration, compatibility, and interoperability keywords map to type:compat. Inference continues after a matching rule has no configured value. Tests cover inference results, explicit type-label precedence, empty results, and mapping parity. The changelog records the type-inference update.

Issue and pull-request title normalization

Layer / File(s) Summary
Prefix grammar and parity tests
scripts/automation/normalize-issue-pr-titles.cjs, scripts/automation/__tests__/normalize-titles.test.js
The CommonJS normalizer requires whitespace after a recognized prefix’s colon. Tests compare the CommonJS and JavaScript normalizers, including malformed decision: and question: titles.

High-Level Assessment

The following are alternative approaches to this PR:

1. Use one shared title normalizer
  • ➕ Eliminates behavioral drift between JavaScript and CommonJS copies
  • ➕ Reduces duplicate implementation and parity-test maintenance
  • ➖ Requires confirming every workflow and consumer supports the chosen module path
  • ➖ Broadens a targeted dormant-workflow fix into a packaging and compatibility change

Recommendation: Keep the PR's targeted correction: canonical rule labels, unmapped-rule fall-through, and parity tests fix the defects without changing shipped entry points. Consolidating the normalizers is a worthwhile follow-up after auditing consumers, but adds unnecessary compatibility risk to this fix.

CHANGELOG.md

The changelog validator flags the literal word "dependency" as a
code-specific implementation detail, which made this PR add one new
critical failure. Reworded to describe the same user-facing change
without it; the validator now reports 0 new failures.

Make the fallback test match an unmapped rule first.

type:bug is checked before type:feature. The current title does not match a bug pattern, so the previous early-return implementation would also return "Feature". Use a title containing fix so the unmapped bug rule matches first and the mapped feature rule is reached later.

The test asserted that an unmapped rule no longer swallows a later matching
rule, but its title ("Improve the documentation and add a feature flag")
matched the mapped type:feature rule first, so it passed without ever reaching
the unmapped path.

"Fix the feature flag" matches the unmapped type:bug rule first and the mapped
type:feature rule second, so the test now fails against the previous
implementation, which returned an empty string.
