/**
 * ontology/serve — the map served as one request-only system piece.
 *
 * Pattern: one pure function over the committed spec (the twin of
 *          `findings/serve.ts · findingsLedgerPiece`): no scope, no I/O, no
 *          clock, no call number. Same spec, same bytes.
 * Role:    Lens. `ontologyPiece` composes the piece `callLLM ·
 *          buildCallLLMStage` joins AFTER the recovery piece and BEFORE the
 *          findings piece (injections → recovery → ontology → findings,
 *          FIXED) and `servedView.ts · viewOf` recomposes from the run
 *          constant `ontology` in the same slot, so the receipt agrees by
 *          construction. It is never pushed into `systemPromptInjections`
 *          (a piece there is exempt from the evidence gate) and never a
 *          `history` turn.
 * Emits:   N/A (the stage emits `agentfootprint.ontology.served`).
 *
 * THE LAW OF THE PIECE
 *   Every line quotes the declaration. The header is a CONSTANT that names
 *   what the piece is, what the framework did NOT do, and the three context
 *   contract meanings the map is the data behind (`lib/context-contract ·
 *   CONTEXT_FIELD_MEANINGS`, one owner, quoted never restated); every other
 *   line is a node, a source, a holding, a relation or an id list, rendered
 *   from the author's own strings. No sentence the library wrote about the
 *   domain. The library never decides that a node "has no data": a node with
 *   no declared source is listed as `known, not held here`, which is what
 *   the author said, not a verdict.
 *
 * THE CACHE
 *   The piece joins the ONE system block a cache marker covers
 *   (`findings/serve.ts` · "The cache"), so it carries no byte that is not a
 *   function of the spec: an unchanged map is served unchanged on every call
 *   of the run and reuses the cached prefix.
 *
 * BOUNDS
 *   `ONTOLOGY_PIECE_LIMITS.sectionLines` lines per section and
 *   `listedIds` ids on the id line, every overflow STATED (`+K more`); an
 *   empty section is omitted, never rendered as "no relations". Every
 *   author string is folded onto one line (`define.ts` already bounds its
 *   length), so no declaration can open a line — or a section — the piece
 *   never counted. Nodes and sources are rendered sorted by id, so two
 *   specs that hash the same (`ontologyHash` is key-order independent)
 *   serve the same bytes; edges keep declaration order, as the hash does.
