scripts/resolvers/gbrain.ts adds:
- generateBrainPreflight(ctx) — emits per-skill ## Brain Context
block + bash that loads digests via
gstack-brain-cache get (one call per
digest). Per-skill subset comes from
SKILL_DIGEST_SUBSETS (single source).
- generateBrainCacheRefresh(ctx) — at-skill-end background refresh hook;
non-blocking; warms cache for next run.
- generateBrainWriteBack(ctx) — Phase 2 / E5 calibration write-back
with per-skill weight. Gated on
personal trust policy + the
BRAIN_CALIBRATION_WRITEBACK flag.
Includes invalidation bash that busts
affected digests after the write.
scripts/resolvers/index.ts registers three new placeholders:
{{BRAIN_PREFLIGHT}}, {{BRAIN_CACHE_REFRESH}}, {{BRAIN_WRITE_BACK}}
All three resolvers return empty string for skills not in
SKILL_DIGEST_SUBSETS (defensive — skill template authors can drop the
placeholders into non-preflight skills with zero effect).
D9 privacy is mentioned in the rendered preflight prose so the agent
knows to expect filtered salience.
D11 codex tension: write-back gates on brain_trust_policy@<hash> being
personal — shared brains skip write-back to avoid polluting team
calibration profile.
test/brain-preflight.test.ts: 19 tests covering subset rendering,
non-preflight skill gating, cross-project vs per-project --project flag
emission, weight injection per skill, BRAIN_CALIBRATION_WRITEBACK flag
mention, and registration in RESOLVERS map.
