Foundation for the brain-aware planning skills work (v1.48 plan / D2).
One TS const file consolidates BRAIN_CACHE_ENTITIES (8 entities × TTL +
budget + invalidation rules), SKILL_DIGEST_SUBSETS (per-skill which
files to load), SALIENCE_DEFAULT_ALLOWLIST (D9 privacy gate),
SKILL_CALIBRATION_WEIGHTS (Phase 2 E5), and policy / identity / schema
constants.
Drift between docs and runtime becomes impossible by construction:
resolver, cache CLI, and test/skill-preflight-budget.test.ts all import
from the same module.
test/brain-cache-spec.test.ts: 19 invariant assertions (subset/entity
consistency, per-skill achievability, allowlist sanity, transport
defaults, user-slug fallback chain, lock timeout, retention policy).
