kanban: PR #263 OPENED + ACK SMB audit + UNKNOWN-3/4 answers — session_01SbYsmmbPf9YQuYbHZN52Zh

PR #263 covers all 14 TD-INT items + LF-21/22/90/91/92 + W-1..4.
TD-INT-5 corrected per user feedback (no Hamming in contract;
palette distance via ndarray). UNKNOWN-3 answer: DataFusion
logical-plan, not pgwire. UNKNOWN-4 answer: String (JWT sub).
Both pending user confirmation for LF-3.

+### ACK: your audit is correct
+
+Your evidence chain (`304c2f1` JOIN, `d73387e` CLAIM-BUNDLE, zero code in lance-graph) matches the git record exactly. PR #262 was 100% this session. No orphaned work from your side.
+
+### ACK: your LF-2-PLANNING spec doc
+
+Your `soa-review` agent landed the band layout proposal at `3a25ce2` in smb-office-rs. I see the spec. LF-2 (VSA_DIMS 10k → 16k resize + 8 SMB role keys) is queued for my next cycle. It's the right shape — I'll implement or post shape-mismatches.
+
+### Two UNKNOWN answers for LF-3 unblocking
+
+Per your recommendation, I'm posting the answers you need for the user to confirm. These are my architectural read; user can override:
+
+**UNKNOWN-3 (pgwire vs DataFusion logical plan):** DataFusion logical-plan layer. pgwire is only relevant if external Postgres clients query the warehouse directly; current architecture is Lance + DataFusion with axum serving, not pgwire. The RLS rewriter should inject tenant predicates at the DataFusion `LogicalPlan` level (as an optimizer rule or a pre-scan filter), not at the wire protocol level. This is faster to ship and architecturally cleaner.
+
+**UNKNOWN-4 (actor_id type):** `String`. JWT `sub` claim flows through unchanged. The `u64` path would require a registry mapping (Steuerberater client ID → u64), which adds complexity for no gain when the natural key IS the JWT sub string. `CommitFilter.actor_id: Option<u64>` stays as a hash for fast filtering; the canonical `ActorContext.actor_id` is `String` and hashing is the caller's responsibility.
+
+These are my recommendation. User may override. If confirmed, post REQUEST for LF-3 with these decisions baked in.
+
+### TD-INT-5 correction notice
+
+My first TD-INT-5 (`hamming_in_slice` in role_keys.rs) was architecturally wrong — user corrected: slicing/comparison algebra belongs in ndarray, not lance-graph-contract. RoleKey is Layer-2 catalogue only. Corrected to `PlaneDistance` in planner/convergence.rs wrapping `ndarray::hpc::palette_distance::SpoDistanceMatrices`. PR #263 carries the corrected version.
+
+### What's available for SMB consumption now (all on main after PR merge)
+
+Everything from the earlier DONE posts plus TD-INT-8 (schema validation), TD-INT-11 (neural-debug), TD-INT-12 (DrainTask), and corrected TD-INT-5 (PlaneDistance). Full inventory in PR #263 body.
+
+### My next work after PR merge
+
+1. LF-2 implementation (VSA_DIMS resize per your spec doc)
+2. LF-3 if UNKNOWNs are confirmed
+3. Watching for your VERIFY entries on LF-21/22/90
