This does not change the `compass.query/1` schema, but intentional score and ordering improvements can change which equally lexical candidate is ranked first; ordering remains deterministic and backend-neutral. +Discovery term indexes preserve their existing full tokens and add bounded +camel-case, acronym, and underscore subwords derived from raw symbol names, +qualified names, and aliases. They also add exact relationship-term postings +from source-backed callable nodes through direct `calls` edges whose evidence +is entirely exact and non-heuristic. Relationship postings use only the called +target's terminal symbol name; namespace and owner terms from its qualified +name remain available to direct lexical recall but do not become caller +evidence. Parallel edges are deduplicated for this recall index; inferred, +ambiguous, mixed-confidence, heuristic, source-less, and non-callable sources +do not participate. + +Direct symbols and candidates with at least two trusted relationship concepts +share one deterministic behavior-ranking channel. They are ordered by +production status, bounded operation-predicate alignment, direct +terminal/owner concept coverage, semantic kind, field and predicate precision, +relationship concept coverage, distinct supporting targets, and evidence +confidence. A relationship candidate keeps its lexical or alias source when +it also has direct indexed evidence; only relationship-only recall is labeled +as a relation seed. Fixed whole-token operation families (including +persistence, dispatch, invocation, processing, recognition, refresh, +resolution, and scheduling) affect ranking only: they cannot add a posting, +candidate, relationship concept, or relation eligibility. Equal evidence +vectors remain explicitly ambiguous. + +Discovery performs at most eight deterministic multi-concept term-index +intersections before independent term unions. Intersection reads spend the +same candidate, posting, object, byte, and probe budgets as all other recall; +exhaustion remains explicit truncation rather than an empty result. A complete +exact-name lookup can prove its top channel despite truncation in lower recall +channels, while duplicate exact names remain ambiguous. + +Discovery traversal bounds adjacency reads by remaining node capacity and +stops endpoint hydration at the node cap. Store-backed final edge assembly +scans unit-valued outgoing references, rejects targets outside the selected +subgraph before record hydration, and resolves the remaining edge IDs through +a bounded shared tree traversal. This preserves canonical parallel-edge order +and exact edge omissions when the reference scan completes; a shared expansion +limit still produces explicit incomplete counts. Exact term candidates and +adjacency records use bounded multi-key tree walks so immutable branch and leaf +objects are decoded once per batch. A pinned request reader retains only +digest-verified, decoded, schema-validated tree objects in an 8 MiB envelope +with a 7 MiB decoded-object budget and a 1,024-object ceiling. Branches are +retained preferentially and leaves use LRU eviction; cache hits do not bypass +any logical item, byte, object, depth, or truncation accounting. + +The immutable store records identifier and relationship capabilities as +separate empty reserved postings in its existing additive terms root, which +older same-major readers ignore. Relationship membership is also stored as a +bounded unit-valued `(source, term)` key so a complete sparse posting can prove +membership in one truncated dense posting without scanning adjacency. The v2 +relationship capability also stores bounded unit-valued +`(source, term, target)` evidence so ranking can count distinct query-supporting +callees without inflating parallel calls or one callee that matches multiple +concepts. Current readers still open snapshots without either capability but +report incomplete discovery coverage; rebuild the graph to make discovery +recall equivalent across the JSON and store engines. The disposable SQLite +query cache adds `relationship_terms(term, source_id)` and +`relationship_term_targets(term, source_id, target_id)` tables, uses internal +format v7, and is rebuilt automatically. + Optional MCP query feedback remains local and disabled by default. `COMPASS_QUERY_LOG=` writes the versioned `compass.query-log/1` JSONL contract up to a 16 MiB file bound.
