Slate Issues Gitcrawl Rebuild

Goal

Rebuild docs/slate-issues from a live gitcrawl mirror instead of the old pre-v2 frozen snapshot. The output should be better triage, not a prettier copy of the April ledger.

Hard Rules

• gitcrawl is the archive-first source for candidate discovery, neighbors, clusters, and stale/duplicate pressure.
• Live GitHub remains final truth for issue state when a claim depends on current status or comments.
• Do not keep the 682-issue snapshot as the active truth if live data disagrees.
• Keep exact Fixes #... claims limited to issue-level proof in docs/slate-v2/ledgers/issue-coverage-matrix.md.
• Document gaps brutally: missing mirror coverage, weak clusters, duplicate-uncertain families, stale rows, no-repro rows, and v2 proof holes.
• No GitHub comments, label writes, closes, commits, pushes, or PRs.

Source Files To Rebuild Or Reconcile

• docs/slate-issues/open-issues-ledger.md
• docs/slate-issues/open-issues-dossiers.md
• docs/slate-issues/test-candidate-map.md
• docs/slate-issues/benchmark-candidate-map.md
• docs/slate-issues/issue-clusters.md
• docs/slate-issues/package-impact-matrix.md
• docs/slate-issues/requirements-from-issues.md
• docs/slate-issues/roadmap-from-issues.md
• docs/slate-issues/triage-close-queue.md

Execution Phases

Phase	Status	Output
1. Mirror refresh	complete	Fresh gitcrawl sync for ianstormtaylor/slate open issues and comments.
2. Cluster build	complete	gitcrawl cluster output plus weak-cluster and singleton gap notes.
3. Gap audit	complete	Current docs vs live mirror deltas: closed, new, missing, stale, weak duplicate candidates.
4. Corpus rebuild	complete	Updated docs/slate-issues summary docs and generated/detailed ledgers.
5. V2 claim reconciliation	complete	Issue coverage matrix claims left unchanged; new live rows stay untriaged until issue-level proof.
6. Verification	complete	Formatting, row/count scripts, bun run completion-check.

Current Findings

• Existing corpus is a 2026-04-02 frozen 682-issue snapshot.
• Gitcrawl live mirror now reports 630 open issues and 29 open PRs: 659 open threads total.
• Gitcrawl hydrated 1856 comments/reviews, embedded 659 rows, and produced 617 clusters.
• Only 28 clusters are multi-member; 589 are singletons. Raw gitcrawl clustering is useful for candidate discovery but too conservative for the Slate v2 architecture taxonomy.
• New live issues absent from the frozen ledger: #6051, #6053.
• Frozen rows no longer live-open: 54; GitHub confirms all are closed.
• V2 exact issue claims are unchanged. The new live ledger preserves old sync status where available and marks new live rows as untriaged-live-new.
