Original recommendation

P2 — Prune legacy/dead labels: priotity/p1 (typo), needs-gpt, type/bug (alongside bug), ad-hoc agent/* labels.

Matched top finding

labels.yaml is now the source of truth (per PR #373), but several legacy/dead labels still exist on the repo and aren't tracked anywhere: priotity/p1 (typo), needs-gpt (deprecated per AGENTS.md lane routing rules), type/bug (alongside the canonical bug), several ad-hoc agent/* labels (agent/Dispatch MCP, agent/OpenCode-Mac, agent/saffron, agent/dispatch-agent).

Evidence:

• gh label list --repo misospace/dispatch --limit 100 --json name minus .github/labels.yaml labels: 22 unmanaged labels.
• AGENTS.md:71 says "Do NOT route to ESCALATED only because labels include… legacy needs-gpt" — so the label is documented as legacy but not removed.

Legacy label cleanup completed.

Removed (9 labels):

Label	Reason
priotity/p1	Typo of priority/p1. No issues, no code references.
agent/Dispatch MCP	Generic identity (AGENTS.md forbids). Only on closed #113.
agent/dispatch-agent	Ad-hoc label. Only on closed #113.
renovate/container	Orphaned Renovate label. Zero issues.
renovate/github-action	Orphaned Renovate label. Zero issues.
type/patch	Semver label. Never used.
type/minor	Semver label. Never used.
type/major	Semver label. Never used.
type/digest	Unused label. Zero issues.

Preserved (documented here):

• needs-gpt — still referenced in src/lib/issue-reconciliation.ts ESCALATION_LABELS and tests; documented as legacy in AGENTS.md.
• type/bug — canonical label per AGENTS.md conventions, referenced in code and 20+ test files.
• agent/saffron — used in test fixtures and docs. Many historical issues carry it.
• agent/OpenCode-Mac — on 2 open issues (P1: /api/issues/reconcile merged PR detection misses body-keyword issue references #302, feat: optionally exclude issues by label from sync and queue #288). Cannot remove while actively assigned.
• agent/opencode — on 9 open/in-progress issues. Actively used.

No .github/labels.yaml source-of-truth file exists; labels are managed directly via GitHub.
