2026-05-21	5399a5ddc36b	bootstrap	8	0	24	0	1	First bootstrap. 1 auto-synthesize target (docs/tribal-knowledge.md) deferred per bootstrap rule — re-run wiki-init to fold it in.
2026-05-22	e504a2b428e4	update	36 (=)	0	(n/a)	0	2	No new pages this run. The B15 auto-synthesize target docs/tribal-knowledge.md (§1-15) is already fully represented in the existing wiki — the merge of PR #861 unioned two independent wiki branches (mine at base-sha 5399a5ddc36b and `4a7c4001` from 2026-05-12), and the older one already covered §11-15 via build/node-paired-files.md, build/scm-variable-scope.md, and bullets in 09-INFRA-PODS.md / 06-CONFIG-POLICY.md. Regenerated .citation-index.json (still empty by_file because `.groovy` is not in the upstream EXT_RE). Surface the dual-hierarchy state in MANIFEST warning #3 so a future cleanup PR can dedupe.
