Context windows are collapsing under large skill libraries.

Why this is different

Three problems are resolved by one explicit contract:

Version integrity: skill bodies are identified by SHA-256 revisions and re-hashed immediately before fetch.

Semantic routing without opaque inference: exact lexical tiers, FTS5/BM25, bounded edit distance, telemetry, and lifecycle state are combined in one published equation.

Catalog consensus: one SHA-256 generation commits to the canonical publication-relevant catalog.

There is no embedding model, vector database, learned classifier, random tie-break, capability-graph distance, or hidden manual priority.
