+## [Main thread / Opus] D-ARM-14 Phase 2 — rebased onto post-#442 main + swapped inline nibble → real contract::hhtl::NiblePath
+
+**Branch:** claude/jolly-cori-clnf9-darm14-p2 (rebased onto main 415971a, #442 merged) | **Files:** `tests/wikidata_landing.rs` (inline `np_*` helpers + inline FieldMask union → real `NiblePath::{root,child,basin,is_ancestor_of,depth,packed}` + `FieldMask::inherit`), STATUS_BOARD (D-ARM-14 row: swap done).
+
+**Cargo:** rebase clean (no conflicts); default **42/42** + clippy clean; `--features landing` `wikidata_landing` green + clippy clean — now landing on the REAL merged `contract::hhtl::NiblePath`. Output shows real depths (person 0x1 d2 → human 0x12 d3), 6→5 collapse holds.
+
+**Outcome:** DONE. User: "442 merged please rebase." #442 put `contract::hhtl::NiblePath` + `FieldMask::inherit` + `ontology::wikidata_hhtl` on main, so the rebase also unlocked the promised inline→real swap (the "swap on #442 merge" remaining item). The worked example now lands on the canonical 16ⁿ router, not a stand-in. Force-push follows (rebase rewrote the 3 P2 commits onto new main). PR #443 updated.

+## [Main thread / Opus] D-ARM-14 Phase 2 — proposer→hub landing (dolce_id emit + worked Wikidata example)
+
+**Branch:** claude/jolly-cori-clnf9-darm14-p2 (off main a77e119) | **Files:** `crates/lance-graph-arm-discovery/src/aerial/ontology.rs` (+`OntologyProjector::dolce_id`, `DolceCategory::from_index`, `is_dolce`), `Cargo.toml` (+`landing` feature + optional `lance-graph-contract` dev-dep), `tests/wikidata_landing.rs` (NEW, gated) + STATUS_BOARD (D-ARM-14 Phase 2).
+
+**Cargo:** DEFAULT (zero-dep) → **42/42** + clippy `-D warnings` clean. `--features landing` → the `wikidata_landing` worked example green + clippy clean (lands on REAL `lance-graph-contract` types).
+
+**Outcome:** Phase 2 DONE. User: "how to use aerial + the 10000² splat + add the ontology to land on Wikidata-shaped HHTL?" → built the answer. **(a) The OD-DOLCE alignment #442 deferred to my lane:** `OntologyProjector::dolce_id()` emits the stable `dolce_id` u8 (= basin nibble, already matching `dolce_id::{ENDURANT=0,..}`) — the proposer hands the hub the enum-free routing key, the IRI becomes a late-resolvable label (resolve-through-cache). **(b) The worked end-to-end example** (`tests/wikidata_landing.rs`, `--features landing`, opt-in `dev-dep lance-graph-contract` exactly like jc's bridge examples — lib stays zero-dep): splat top-k → `extract_rules` recovers all 6 DOLCE basins → lands each on the REAL `contract::class_view::FieldMask` (presence) + `hash::fnv1a_str` (StructuralSignature value); `NiblePath` 16ⁿ routing inlined (annotated, swap on #442 merge since contract::hhtl isn't on main yet). CONFIRMED on data: corpus collapses 6→5 families (film Q11424 ≡ tv Q5398426, sig 0xad7fade7), human⊂person inherits path + mask-as-delta, basin preserved down the subclass path. Respects the firewall (lib never imports the hub; the test bridges both to prove the `(ClassId, signature, FieldMask)` triple + `dolce_id` u8 seam). NOT pushed yet — awaiting confirm (prior branch merged). Map: `splat-codebook-aerial-wikidata-compression.md`.

+## 2026-05-31 — FINDING: ANY OWL/DOLCE domain compartmentalizes into the same 16ⁿ HHTL, fed by aerial — the class-meta-DTO is the universal substrate; domains differ in content, never structure (D-ARM-14 Phase 2)
+
+**Status:** FINDING (per-layer domain-independence is shipped/proven on 2 domains; full-scale universality is CONJECTURE — each new domain is a falsifier). Doc: `owl-dolce-hhtl-compartments-aerial-fed.md`. PR: D-ARM-14 Phase 2 (`claude/jolly-cori-clnf9-darm14-p2`).
+
+**The generalization (the user's "potential"):** medicine (SNOMED/FMA), finance (FIBO), geography, law, Odoo, and all of Wikidata are NOT bespoke loaders — each yields the SAME four things and lands as the SAME `(ClassId, StructuralSignature, FieldMask)` row: a **basin** (DOLCE `dolce_id` 0..3), a **nibble path** (`NiblePath`, P279 subClassOf descent), a **`FieldMask`** (property presence), a **`StructuralSignature`** (FNV-1a shape-family). Domain enters only as *content* (the property-id set + the corpus), never as *structure*. This is `cognitive-risc-classes.md` N4 operationalised — "chess + Odoo + Wikidata-anatomy through one Class+SoA+HHTL+CAM, no special-case."
+
+**Why it holds (proof chain, not hope):** every layer is domain-agnostic by construction — `NiblePath` takes a `basin: u8` with zero DOLCE knowledge (#442); `FieldMask` is one-bit-per-property (#441); `StructuralSignature` is label/QID/domain-independent (Odoo #441 + Wikidata #442 BOTH collapse structurally-identical classes to one family); `ClassView` is a trait both `RegistryClassView` (Odoo) and `WikidataClassView` (Wikidata) impl unchanged. DOLCE is resolved late from the cache (`basin = dolce_id`, no enum). The **aerial feed** is the part that makes each domain self-populating: similarity is an injected integer `CodebookDistance` (the 10000² splat, jc-certified), so a new domain is fed by pointing aerial at (a) a domain splat codebook + (b) a domain row corpus — `tests/wikidata_landing.rs` is the template; swap the fixture, **no new hub code**. Phase 2 proved this end-to-end (splat → recover 6 DOLCE basins → land on real `FieldMask`+signature; film≡tv collapse, human⊂person inherit).
+
+**Compartmentalization rule:** ONE tree axis (Abstammung/P279), DOLCE facets seed root nibbles 0x0..0x3 (0x4..0xF reserved). The DOMAIN is an ORTHOGONAL compartment (namespace/facet tag), NOT a second path — cross-domain multi-typing is a facet bit in the same `FieldMask`, like bat = mammal-path + flight-bit. Open: reconcile the OGIT *byte*-basins (0x10..) with the `NiblePath` *nibble*-basin before a multi-domain load.
+
+**Scale-freezes (carry from the #442 review):** `NiblePath` silent truncation at depth-16 (deep medical/bio chains collide), `StructuralSignature` u32 (birthday-collision among shape-families across many domains), the DOLCE nibble/byte addressing. None bites the 2 curated domains; all bite at full multi-domain scale — name each as a conscious freeze before the load that needs it. Gated on D-ARM-7 (`jc::jirak`) before any domain's feed writes the store.
+
+**Cross-ref:** `owl-dolce-hhtl-compartments-aerial-fed.md`, `wikidata-hhtl-load.md`, `ogit-owl-dolce-ontology-compartments.md`, `splat-codebook-aerial-wikidata-compression.md`; #441 (D-CLS), #442 (Wikidata-HHTL), #438 + Phase 2 (aerial feed); the D-CLS↔D-ARM-14 convergence FINDING; `cognitive-risc-classes.md` N4.
