- Replace `renderGroupedChanges` with `polishFragmentsWithClaude` that pipes fragments through `claude -p --model sonnet` to merge related items, drop housekeeping noise, and produce user-facing release notes
- Internal fragments kept in CHANGELOG.md under a `<details>` collapse; dropped from GitHub release notes entirely
- CI no longer auto-runs `changelog:build` on tag-based releases — fails fast with a clear error if `changes/*.md` fragments are still pending; build locally and commit before tagging
- Add `runClaude` dep-injection seam to test surface; add failure-mode coverage (missing binary, empty output, missing headers, missing `<details>` wrapper)
- Delete implemented design doc; update `changes/README.md` and `docs/RELEASING.md` with claude CLI prerequisite and new workflow
- Capture decisions from brainstorming: replace bullet renderer with `claude -p`, write straight to disk, hard-fail on missing/failed claude, drop internal section from release notes but keep collapsed in CHANGELOG.md
- Document prompt input/output contract, affected files, test plan, and CI guard that fails tag-based releases when changelog fragments are still pending
- Set scope boundaries (no caching, no SDK fallback, no `--no-polish` escape hatch)
- Add Arch Linux `subminer-bin` install instructions to README and docs-site installation guide
- Add Hyprland troubleshooting guidance for transparency and global shortcut passthrough
- Add TASK-159..164 backlog records and skill design plans; include changelog fragment
- Apply formatting-only update to `src/release-workflow.test.ts`
