Operator-invoked, operator-gated loop:
- --gather reads published bodies directly (parsePublishedRecord, filtered by
published_date > last_run) + current profile, for the session to extract candidates.
- --propose validates candidates (shape + single-line key/value, else non-zero/no-write),
proposeDiff, writes brain/pending-diff.{json,md}; never touches profile.md.
- --apply --diff <json> --confirm is the ONLY path that writes profile.md (refuses
without --confirm), then records brain/consolidation-state.json last_run.
init/ingest/published preserved. 7 subprocess CLI tests (SC5). brain 75→82, tsc clean.

Add flag-routing infra (parseFlags) + two subcommands to the brain CLI, keeping
the existing `init` branch intact:
- `ingest --file <path> [--source] [--date]` / `ingest --scan-inbox` → capture
published posts into ingest/published/ (Wrote / Duplicate / Collision report).
- `published list [--json]` → inspect the gold corpus (id · provenance · date · first line).
6 subprocess tests incl. an explicit `init` regression guard. brain 57→63 tests, tsc clean.

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.

SB-S0 (Foundation) of the second-brain arc: a new TS package scripts/brain/
(structural copy of specifics-bank) establishing the spine later slices hang on.
TDD throughout (failing test first); fold scope = P1+P2 only per operator decision.
- types.ts: one provenance vocab (human|published|ai-draft) + the six-field
ProfileFact record + two-layer ProfileDoc.
- id.ts: slugify + mintEntityId (sha256[:12], kind-namespaced, slug-keyed so the
id is stable across value edits) + normalizeProvenance (throws on unknown). [SC4]
- profile.ts: no-YAML line-grammar parse/serialize (parse∘serialize = identity over
the whole doc; values may contain ]/|/quotes) [SC2] + foldUserProfile: lossless,
idempotent, source-absent-aware fold of config/user-profile.template.md. Pinned
extraction — P1 labeled scalars (group-headers skipped, [placeholder]→empty) + P2
expertise group; stops at "### Research Tooling" so deferred explainer prose can't
leak in as fields. Checkbox-prefs (Goals/Tone/MCPs/Assets) deferred (§8). [SC3]
- dataRoot.ts: inline per-package resolver (repo idiom; no new seam → SC6).
- scaffold.ts/cli.ts: idempotent `brain init` — brain/{index,profile,operations}.md
+ journal/ + ingest/{inbox,published} under the data-dir; compare-then-skip, never
clobbers a user edit. No session-start wiring (SB-S2 owns it). [SC1]
Gate: new BRAIN floor in test-runner.sh (34 tests; trends/specifics/contract floors
unchanged) + anti-erosion floor 74→75. Full gate 90/0/0, tsc --noEmit clean. [SC5/SC6]
No new command/agent/reference → no version bump, no structure-count change.
