 - **Safe Footer Injection frontmatter detection** — Extended YAML frontmatter detection to support variable-length headers by searching entire file instead of limited line count. Changed delimiter matching to exact match `trim() === '---'` to prevent false positives on YAML content lines. ([PR #1632](https://github.com/lightspeedwp/.github/pull/1632))
 
-- **Phase 3 label validation enforcement — Validation script & workflow** — Pre-creation label validation script (`validate-labels-before-creation.cjs`) enforces canonical label prefixes and one-hot constraint per family. GitHub Actions workflow validates on issue/PR creation, editing, labeling, and PR synchronization. Prevents bare labels (e.g., `bug`, `feature`, `urgent`) and enforces required prefixes (e.g., `type:bug`, `priority:critical`). ([PR #1613](https://github.com/lightspeedwp/.github/pull/1613), [#1612](https://github.com/lightspeedwp/.github/issues/1612))

-- **Phase 1 critical fixes — broken badges and release process** — Fixed 33 broken documentation badges (workflow status, build badges); fixed release workflow to default to `--dry-run` with explicit `--live` flag requirement; added authorization gating for release operations. ([PR #1609](https://github.com/lightspeedwp/.github/pull/1609), [#1547](https://github.com/lightspeedwp/.github/issues/1547), [#1548](https://github.com/lightspeedwp/.github/issues/1548), [#1549](https://github.com/lightspeedwp/.github/issues/1549))

-- **Address Copilot review feedback on PR #1591** — Fixed broken relative paths in audit report files and adjusted path resolution for portable asset locations. ([PR #1610](https://github.com/lightspeedwp/.github/pull/1610), [#1591](https://github.com/lightspeedwp/.github/issues/1591))
-
 - **Fix README frontmatter** — Corrected Phase 2B project README frontmatter. ([PR #1540](https://github.com/lightspeedwp/.github/pull/1540), [#1375](https://github.com/lightspeedwp/.github/issues/1375))

 - **Gitleaks secret scanning** — Added `gitleaks-reusable.yml`, an organisation-wide reusable workflow other repositories call via `workflow_call`, plus a `gitleaks.yml` caller running on pull requests into `develop`/`main`. Runs the open-source Gitleaks CLI directly (the `gitleaks-action` wrapper requires a paid licence for organisation repositories). Per-PR runs scan the working tree; `workflow_dispatch` accepts a `full-history` input for on-demand full-history rescans. A baseline full-history scan of this repository returned 50 hits, all verified as placeholder values in documentation and tests, allowlisted in `.gitleaks.toml`. ([PR #1444](https://github.com/lightspeedwp/.github/pull/1444))
 
-- **Phase 1–3 completion documentation** — Comprehensive project completion report documenting Phase 1 restructuring, Phase 2 label remediation, and Phase 3 validation enforcement. Includes audit findings, 5-phase remediation timeline, and governance architecture. ([PR #1624](https://github.com/lightspeedwp/.github/pull/1624))
-
-- **Label creation governance in CLAUDE.md and AGENTS.md** — Added mandatory label prefix enforcement rules to organisation-wide governance documents. All labels must use canonical prefixes (type:, status:, priority:, area:, etc.) from `.github/labels.yml` (158 canonical labels). One-hot constraint per family except meta:, comp:, lang: which allow multiples. Prevents bare labels and enforces validation at issue/PR creation time. ([PR #1611](https://github.com/lightspeedwp/.github/pull/1611))
-
-- **Phase 4 label validation documentation** — Comprehensive documentation package: updated LABELING.md v1.1.0 with ~500 lines on validation rules and error guidance; new LABELING_FAQ.md (~2,500 lines) with 30+ FAQs organized by topic; new LABELING_EXAMPLES.md (~1,000 lines) with 20+ real-world label combinations for issues and PRs. ([PR #1613](https://github.com/lightspeedwp/.github/pull/1613), [docs/LABELING.md](./docs/LABELING.md), [docs/LABELING_FAQ.md](./docs/LABELING_FAQ.md), [docs/LABELING_EXAMPLES.md](./docs/LABELING_EXAMPLES.md))

 - **Add Gitleaks scanning** — Reusable workflows for PR secret scanning. ([PR #1444](https://github.com/lightspeedwp/.github/pull/1444))
 
 - **Phase 1 repo restructuring** — Moved scripts/website/projects to .github; updated 400+ refs. ([PR #1446](https://github.com/lightspeedwp/.github/pull/1446), [#1447](https://github.com/lightspeedwp/.github/issues/1447))
