chore(contract): address #480 CodeRabbit review + CI status badges#481
Merged
Conversation
Follow-up on merged PR #480 (D-IDENTITY-1 Phase A). Substantive: - hhtl: focused from_packed edge-case test — depth>MAX_DEPTH and high-bits-set rejection, (0,0)->EMPTY sentinel, the MAX_DEPTH boundary that exercises the used_bits<64 guard (avoids >>64 UB), and packed o from_packed identity. - plan: the stale "one open DECISION" line conflicted with the RESOLVED block above it -> now a RESOLVED status line (decision landed in NodeGuid). - plan: add the no-content-drift-for-existing invariant — an existing entity's identity is a derived function of its ontology-mapped class, so it cannot drift; the sole drift surface is an ontology cache not mapped from its authoritative source, which is exactly what the shape_hash witness guards. - AGENT_LOG: add the commit SHA to the D-IDENTITY-1 entry (traceability). Cosmetic (markdownlint, the two new plan docs): - MD040: language tag on the MAP1/MAP5 fenced diagrams. - MD058: blank lines around the Layer 0-6 inventory tables. - Skipped MD028 in LATEST_STATE: the blank line between board entries is the file's append-only style; "fixing" one entry diverges it from all priors. Tooling: - README: native GitHub Actions status badges (Rust Tests / Style Check / Build). Chose native badge URLs over the marketplace ci-badges action — zero-config, no workflow step or write-back token, no maintenance surface. 600 contract lib tests (+1); clippy -D warnings --all-targets clean; fmt clean. https://claude.ai/code/session_014A4JuRCqKP2yNENrQ9Ha7H

Two architecture decisions for the identity arc (plan + epiphany; no code): 1. Ontology-cache home = OGAR, a one-way mirror of OGIT (+ OWL / Wikidata class-backbone / HHTL) with an append-only immutable ClassId space (protobuf-field-number discipline). Chosen for ownership + dissolving the upstream dependency, NOT as a drift fix -- content-drift for existing entities does not exist once the cache is mapped from a source; the mirror buys ownership, and pre-production immutable ClassIds make NodeGuid stable-forever rather than stable-within-an-OGIT-version. 2. The ClassId space is a shared north-star template spine, not a flat domain x shape explosion: entity_type/NiblePath is the DOLCE-rooted shape (reused across domains), namespace:u8 is the domain. Reuse a template by default (switch namespace, inherit field-set); specialize via NiblePath descent + FieldMask delta; mint new only for a genuinely novel shape. This is the intended reading of the existing octet split + FieldMask inherit/delta + NiblePath ancestry -- mechanism exists, the curated template ontology is the OGAR/Phase B content. Frugal (shape encoded once, reused 256 ways) and composes with immutability (templates ARE the immutable spine). Plan: identity-architecture DECISION-2 + north-star guard + Phase B row. Epiphany: E-OGAR-NORTHSTAR-1. Board: AGENT_LOG. https://claude.ai/code/session_014A4JuRCqKP2yNENrQ9Ha7H
…supervision-edge = template specialization Cross-session convergence: a parallel OGAR/SurrealDB session pulled #480 and independently re-derived the OGAR<->lance-graph membrane as the registry mint of (entity_type, NiblePath) per class -- exactly DECISION-2 (OGAR mirror) from #481. New synthesis: NiblePath::is_ancestor_of (one HHTL bit-shift on the GUID prefix) is three relations at once -- OWL subClassOf, OTP supervision edge, and north-star template specialization. The template hierarchy IS the routing/supervision hierarchy IS the subclass hierarchy; no separate routing structure to maintain. https://claude.ai/code/session_014A4JuRCqKP2yNENrQ9Ha7H

…moves Grounded the live registry surfaces before proposing Phase B: - contract/ontology.rs:85 entity_type_id() is a 1-based POSITIONAL index into Ontology.schemas (mutable: insert/reorder renumbers everything) -- the legacy anti-pattern in our own code. - lance-graph-ontology/registry.rs OntologyRegistry is APPEND-ONLY (RegistryState::append, 'no rebuild per append') -- the correct immutable home, and already frugal: enumerate_first_with_entity_type_id shows N MappingRows -> 1 entity_type (one template reused across namespaces) is already legal. Four frugal moves recorded in the plan: (1) mint in the append-only registry, deduped by template (domains reuse via namespace, not a fresh entity_type); (2) pair entity_type <-> NiblePath at mint; (3) build-time round-trip test makes eineindeutigkeit CI-falsifiable; (4) feature-gate the legacy positional helper per I-LEGACY-API-FEATURE-GATED. https://claude.ai/code/session_014A4JuRCqKP2yNENrQ9Ha7H
Decision-gate ratified: entity_type is GLOBAL (the shared north-star template id), not namespace-local. The pre-change trace then overturned two beliefs: - namespace.rs:12 'dense within the namespace' is a STALE doc comment -- the live mint (registry.rs:476, entity_type_id = rows.len()+1) is already global append-order across all namespaces. The ratified semantics are the live behavior; only the prose and the dedup are missing. - The registry is NOT template-deduped (corrects this session's own 'already leans frugal' claim): every append mints fresh. Dedup + the entity_type<->NiblePath pairing are net-new. Blast radius traced benign: ~16 entity_type_id() readers store or compare; none dense-index by entity_type. Synthesis recorded: the bijection IS the dedup -- one NiblePath<->entity_type pair table is the template registry, the dedup index, and the bijection witness at once (Phase B moves 1+2 = one mechanism). Plan: DECISION-3 + CORRECTION block + refinement. Board: E-MINT-TRACE-1, E-OGAR-NORTHSTAR-1 Status line, AGENT_LOG. https://claude.ai/code/session_014A4JuRCqKP2yNENrQ9Ha7H

Added the no-content-drift-for-existing guard to the identity plan: an existing entity's identity is a derived function of its ontology-mapped class (
entity_type/NiblePath/shape_hashall fall out of the registry mapping), so a mapped entity cannot drift from its content. The sole residual drift surface is an ontology cache not mapped from its authoritative source — which is exactly what theshape_hashwitness reading ofNodeGuidguards.CI badges
