Writers that created or rewrote brain files by path followed symlinks: - promote/reject: os.MkdirAll + os.WriteFile of the destination, then os.Remove of the raw source. Now PutRegular + brainfs.Remove; the source is kept when the write is refused. - StampProvenanceFile (brain_edit's re-stamp): provenance.ApplyFile read and rewrote by path. Now ReadRegular + WriteRegular; ApplyFile, now unused, is removed. - BuildWingIndex (_index.md) and wiki.RebuildIndex (wiki/index.md): now PutRegular. - wiki.AppendLog (log.md) and AutoTunnel's fuzzy-candidate log (raw/tunnel-candidates-*.md): now AppendRegular; tunnel's fileExists, now unused, is removed. - New brainfs.Remove: clean path, real parent, removes a final symlink itself, never its target. brain_edit's own atomic rename was already refused behind a symlinked directory by #187's read check; a guard test pins it. Pipeline writes, BackfillRefs, the watcher's raw/ markers and the session archive in cmd/server follow in a separate PR (#158). Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
