Idempotent, collision-safe, create-on-demand IO under the brain dataRoot:
- writePublished: identical body → no-op; differing body at same id → disambiguated
<id>-N.md (never clobber, never silently drop a gold record, B2 defence-in-depth).
- ingestText: provenance always published; published_date defaults to captured_at.
- scanInbox: top-level *.md only (skips .DS_Store/dotfiles/non-md), non-destructive,
empty/absent inbox = clean no-op, re-scan re-skips via dedup.
- listPublished: parses each file in try/catch (malformed → skipped count, never
crashes), surfaces provenance so ai-draft leakage is eyeball-visible.
9 temp-dir IO tests. brain 48→57 tests, tsc clean.
