entry preserves the trail. Two same-day MedCareV2 PRs are kept as separate

…r VSA-scope correction

pattern.md (NEW, 578 lines) — usability patterns for traversing the
workspace's SoA/DTO surface as a graph (nodes = type defs, edges =
producer-consumer + duplicate + seam, subgraphs = clusters). 15 named
patterns covering canonical lookup, maturity scoring, Click-P-1 lens,
register-laziness check, dual-tier writes, ingestion-commit, lineage-
as-column, append-only governance, consult-first ordering, cross-
session blackboard via ledger row IDs, source-vs-claim divergence,
cluster-fix discipline, debug-as-API debt, scope-lock, and seam-naming.
Plus 7 critical findings and append-only update protocol.

VSA scope correction per CLAUDE.md I-VSA-IDENTITIES iron rule:
- VSA-1 description tightened: Vsa16kF32 is for Markov chain over
  identity fingerprints exclusively. Provenance / JWT / RBAC / IDs
  are register territory, not VSA carriers.
- PERMUTE-1 description tightened: vsa_permute is unitary as an
  operation but the braiding usage is NOT lossless; cross-talk
  shrinks unbinding margin with N. Bound: N <= sqrt(d)/4.

New rows:
- EWA-SANDWICH-1 (PR #289 was missing from initial snapshot):
  Stage 3 / Smart / entropy 2. Scope: SPD-bounded propagation of
  cognitive Vsa16kF32 across Markov rho^d cycles. NOT a lineage
  error model (corrected from initial framing).
- SUBJECT-DTO-1: aspirational typed Subject struct with
  AuthSource enum (typed JwtClaims, not VSA). Implied by
  MedCareV2 #7+#8 wire shape.
- MOCK-DRIVER-1: q2 PR #35 Phase-3 placeholder, Stage 2.

Cross-repo resolution events:
- THINK-1 partial: q2 PR #35 dropped thinking-engine +
  cognitive-shader-driver deps from cockpit-server, migrated to
  canonical contract::cognitive_shader::*. Wire compression
  256x on cycle_fingerprint, 128x on color_acc.
- TRUTH-1 partial: q2 PR #35 cockpit-server bridges to
  lance-graph-planner::nars::truth::TruthValue::deduction.
- POLICY-1 + MEMBRANE-GATE-1: priority bump — MedCareV2 #8 now
  blocking on impl MembraneGate for Arc<rbac::Policy>.

Section G — ingestion-vs-traversal axis added: Cypher-parser path
(Option 1, ships now via PARSER-1 resolution) and splat-deposit path
(Option 2, gated by SPLAT-1) both converge on E1 typed Action API.

Retractions: E4 (VSA-bundled provenance) and E8 (geometrically-
bounded provenance via Vsa16kF32+EWA) — register laziness; do NOT
get appended to EPIPHANIES.md. E1, E2, E3, E5, E6, E7, E9 stand.
