+## 2026-06-23 (cont.³⁹) — V3 (part_of:is_a) 8:8 tile for the electric grid + q2 V1/V2→V3 consumer-awareness
+
+**Main thread (Opus), operator-directed.** Operator: read q2 `OGAR_CONSUMER_INTEGRATION.md` + `V3_SOA_WIRING.md`, check which lance-graph/OGAR consumers need the V1/V2→V3 (`part_of:is_a`) bump, focus first on representing the Spain electric grid better with V3. **Access:** pygithub/api.github.com is org-app-gated (403) — but `raw.githubusercontent.com` + `GH_TOKEN` works (different host, dodges the gate); fetched both docs that way. **V3 insight:** each 16-bit HHTL tier is an 8:8 split — high byte = `part_of` (PLACE/where, mereology), low byte = `is_a` (TISSUE/what, taxonomy); high-byte chain prefix-routes containment, low-byte chain prefix-routes type; `EdgeBlock` in-family = `part_of` siblings = `connected_to`. V3 needs **no layout change** (interpretation of the locked 3×u16). **Consumer-awareness (reported):** lance-graph `canonical_node` (no 8:8 accessor — additive opportunity); my `cascade_key` #605 (V1/V2 spatial-only → bumped here); `contract::soa_graph`/`graph_render`; **live blocker** q2 `osint-bake/fma.rs` calls `NodeGuid::new_v2(...LEAF...)` — a 7-group API that does NOT exist in `canonical_node` (the doc flags it as `I-LEGACY-API-FEATURE-GATED`; V3 sidesteps it — 6-group-compatible). Did NOT touch that gate (other session's OGAR/contract surface) — flagged only. **Shipped (`perturbation-sim/src/cascade_key.rs`, additive to #605):** `IsaPath {class,kind,sub}` (the is_a low-byte chain) + `CascadeKeyV3 {heel,hip,twig}` (each tier `(place<<8)|tissue`) + `place_chain`/`tissue_chain`/`part_of_distance`/`is_a_distance`/`to_guid_tiers` + `cascade_keys_v3(grid, alive, &[IsaPath])` (place = 24-bit Morton spectral cell, 3 octets; tissue = is_a taxonomy). For the grid: `part_of` prefix = "which region blacked out", `is_a` prefix = "all generators/loads" — two orthogonal queries on ONE key (V1/V2 spatial-only couldn't). **+4 V3 tests (9 total green):** 8:8 packing, axis-independence, blackout part_of-locality + is_a separability (source vs sink distinct class bytes), isa-count guard. Example `spain_cascade.rs` extended with the V3 dual-query (source/sink roles read off the is_a byte). clippy `-D warnings` clean, fmt-clean. EPIPHANIES `E-V3-PART-OF-IS-A-TILE`. Rides a PR on jirak.
+## 2026-06-23 (cont.³⁸) — electric-outage cascade wired onto the FULL 16-bit-per-tier spatial key (leaf/family/identity = HEEL/HIP/TWIG) — one key, six lenses
+
+**Main thread (Opus), operator-directed.** Operator: read q2 + OGAR spatial representation, then re-wire the Spain-blackout cascade with leaf-16/family-16/identity-16 perfectly aligned with the cascade — "proves location, math, learning, representation, substrate, thinking." Grounded on OGAR P0 canon (256×256 centroid tile / Morton / 3×4) + ndarray `guid-prefix-shape-routing.md` §4/§4b (the key selects the grid; deterministic-phase pyramid). *(pygithub for q2/OGAR was proxy-gated — Claude GitHub App not connected for the org, 403 — but OGAR's spatial canon is in-context + the ndarray spatial doc is local, which IS the representation source; q2 is the downstream renderer, not the encoding.)* **NEW `perturbation-sim/src/cascade_key.rs`:** `CascadeKey { family:u16, leaf:u16, identity:u16 }` — the OGAR **production form** the existing `hhtl.rs` explicitly defers ("binary-Cheeger fills only the low bit per tier, NOT that full encoding"). Each tier = a full 16-bit 256×256 centroid tile (two byte-axes, nibble-interleaved `splat::morton2`) built from the bus's `basin::spectral_embedding` position (electrical coords, "topology IS the key"); 3 tiers ⇒ 24-bit-per-axis Morton, coarse→fine = HEEL/HIP/TWIG. Methods: `from_spectral`, `to_guid_tiers` (the canonical (HEEL,HIP,TWIG) triple), `morton48` (packed SoA key), `shared_prefix_tiers`/`cascade_distance` (O(1) Morton-containment), `tile` (decode→spectral tile). `cascade_keys(grid, alive)` assigns all buses (min-max norm ⇒ prefix = quad-tree ancestry, the 4⁴ condition). **+5 tests + example `spain_cascade.rs`.** The six lenses PROVEN: location (tile decode), math (`cascade_distance` bus0-bus1=0 / bus0-bus11=3), representation+substrate (family/leaf/identity = HEEL/HIP/TWIG u16, morton48 bit-exact), **learning+thinking — the blackout epicentre is prefix-local: mean cascade-distance 1.000 ≪ 2.561 random baseline** (the footprint learns the basin tree; the cascade traverses the same key). Zero-dep, deterministic; `cargo test … cascade_key` 5/5, clippy `-D warnings` clean, my files fmt-clean (pre-existing `chaoda_surge_epicenter.rs` fmt drift left untouched — not my change). The Spain perturbation artifact extended additively, never deleted. EPIPHANIES `E-CASCADE-KEY-IS-THE-SPATIAL-ADDRESS`. Rides a PR on jirak.
 ## 2026-06-23 (cont.³⁷) — sealed the capstone OUT/IN-leg public surface + end-to-end mixed-trigger test
 
 **Main thread (Opus), self-directed ("what do you want").** Disk reality: ~11 GB free vs ~14-18 GB for the lance/datafusion build (ENOSPC'd twice) → S3-live is **disk-walled in this env**, not permission-gated; its home is the symbiont golden-image harness (already pulls lance-7). So took the feasible completion: made the shipped OUT/IN-leg drivers an actual crate surface. `lance-graph-supervisor/lib.rs` now re-exports `deliver_kanban_step`, `drive_mul_advance`, `drive_scheduled_tick`, `drive_version_tick`, `run_to_absorbing`, `KanbanRouteError` (were module-path-only; only `KanbanActor`/`KanbanMsg` were public) — the surface the live S3 consumer will `use` when it lands. **+1 test (15 total green):** `mixed_triggers_compose_on_one_owner_s2_gate_then_s3_ticks` — the capstone integration: the S2 MUL gate takes the first Rubicon step (Flow qualia → Planning→CognitiveWork) and S3 version ticks (`run_to_absorbing`) carry the rest to Commit, proving the two DIFFERENT triggers compose on ONE mailbox-as-owner (no panic, no spurious rejection, lands absorbing). clippy + fmt clean; light build. The actor-side capstone is now a sealed, consumable surface; only the disk-gated live wiring (S3 `versions()` source, S2 shader-driver loop) remains, to be done where the heavy build fits. Rides a PR on jirak.

+## 2026-06-23 — E-V3-PART-OF-IS-A-TILE — each 16-bit HHTL tier is an 8:8 (part_of:is_a) split: two hierarchies, one key
+
+**Status:** FINDING (q2 `converge.rs` / `V3_SOA_WIRING.md` are the existence proof on FMA anatomy; this entry records the grid instance + the consumer-bump awareness). **Confidence:** the 8:8 split + dual-query are shipped/tested; the consumer-bump items are an inventory, not yet PRs.
+
+q2's V3 addressing reinterprets each canonical 16-bit HHTL tier as **high byte = `part_of`** (PLACE / mereology / where) **: low byte = `is_a`** (TISSUE / taxonomy / what). The high-byte chain (HEEL.hi→HIP.hi→TWIG.hi) prefix-routes containment; the low-byte chain routes type. `EdgeBlock` in-family = `part_of` siblings = `connected_to`. **It needs no `ENVELOPE_LAYOUT_VERSION` bump** — it is an *interpretation* of the operator-locked 3×u16 tiers (the 6-group `NodeGuid`, NOT the in-flight 7-group LEAF `new_v2`).
+
+For the **electric grid** (`perturbation-sim::CascadeKeyV3`, additive to the V1/V2 `CascadeKey`): `part_of` (place) = the 24-bit Morton spectral cell (where in the grid), `is_a` (tissue) = the bus-role taxonomy (source/sink/transfer, generalizable to `BusKind`). The payoff over V1/V2 spatial-only: a `part_of` prefix selects "which region blacked out" AND an `is_a` prefix selects "all generators / all loads" — **two orthogonal queries on ONE key** (proven: source vs sink carry distinct is_a class bytes; the outage footprint is part_of-local). EdgeBlock in-family = the lines the cascade propagates along.
+
+**Consumer V1/V2→V3 bump inventory:** lance-graph `canonical_node` lacks an 8:8 `(part_of/is_a)` byte accessor (additive, layout-preserving — the natural canonical surface); `contract::soa_graph`/`graph_render` could split place/tissue on render; **live blocker** — q2 `osint-bake/fma.rs` calls `NodeGuid::new_v2(...LEAF...)`, a 7-group API absent from `canonical_node` (`I-LEGACY-API-FEATURE-GATED`); V3 is the 6-group-compatible resolution that sidesteps it.

+## 2026-06-23 — E-CASCADE-KEY-IS-THE-SPATIAL-ADDRESS — one 48-bit Morton key, read six ways
+
+**Status:** FINDING (measured, scoped to perturbation-sim). **Confidence:** the
+locality result is a measured probe, not a proof; the six-lens *identity* is
+structural.
+
+The electric-outage cascade re-wired onto `perturbation-sim::CascadeKey`
+(`family:u16 | leaf:u16 | identity:u16` = HEEL/HIP/TWIG, the OGAR production form
+the old binary-Cheeger `HhtlKey` defers). Each tier is a full 16-bit 256×256
+centroid tile of the bus's `spectral_embedding` position (Morton-interleaved,
+min-max norm ⇒ nibble prefix = quad-tree ancestry, the 4⁴ condition). The same
+key is six readings of one address, NOT six artifacts:
+
+- **location** = `tile()` decode (the address is the position);
+- **math** = `cascade_distance` = `3 − shared_prefix_tiers`, O(1) Morton
+  containment, zero value decode;
+- **representation** = `to_guid_tiers()` IS the canonical `(HEEL,HIP,TWIG)`;
+- **substrate** = three `u16` = the `NodeGuid` cascade tiers at bytes 4..10;
+  `morton48()` = the packed SoA key;
+- **learning + thinking** = the blackout epicentre is **prefix-local** — measured
+  mean cascade-distance **1.000 vs 2.561 random baseline** on the 3-region grid;
+  the footprint learns the basin tree and the cascade traverses the same key.
+
+This realizes `guid-prefix-shape-routing.md` §4 ("the key selects the grid") on a
+real perturbation domain. Honest fences: spectrally-symmetric buses (a clique)
+collide at the finest tier (degenerate eigenvectors — broken symmetry separates
+them in real grids); the locality number is a single-probe measurement (cite
+Jirak `n^(p/2−1)`, not IID, for any significance claim per I-NOISE-FLOOR-JIRAK);
+"topology IS the key" — these are electrical (spectral) coordinates, not geography.
