Every brain write accepted [[targets]] that resolve to nothing — skill names, repo names, agent-local memory-file slugs — and each one became a permanent [high] broken-link finding. The brain-audit digest grew 19 -> 63 high findings between 2026-08-26 and 2026-09-16; 53 of the 63 were exactly this, and none are fixable by brain-gardener's BrokenLinkFixer, which only repoints edit-distance-1 renames. There is no target to repoint to. StripUnresolvedLinks resolves each link against knowledge/ + wiki/ using brain-gardener's own resolver semantics (bare slug or wing/hall/slug path form, code spans excluded) and unwraps the misses to plain text, reporting them as Ref.Unlinked / the MCP `unlinked` field. Unwrap rather than reject: a refused write on claudewatcher's unattended ingest path is a lost learning, and the author's words are worth keeping even when the link is not. An empty corpus is a no-op, so a misconfigured brainDir cannot strip every link in a note. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>
