MARK V — VERSIONING POLICY (WIP)
================================================================================
1. PLANES (do not collapse)

  CORE_LAW        Immutable principles (Create No Victims, features never
                  redefine CORE, Catcher veto, no secrets in MU body).
                  Change only with Catcher grant + MU lineage.

  SILICON_CORE    Term registry + dual-path tip body (S1, S2...).
                  Identified by SYNC_CODE + SILICON_REV.

  PROTOCOL_SPEC   This executable package (OpenAPI, FSMs, SHALL).
                  Identified by SPEC_VERSION (semver).

  FEATURES        Optional mounts (mesh mail, wish pool, HITL glass...).
                  Never rewrite CORE_LAW. May require min SPEC_VERSION.

2. TIP FIELDS (CURRENT.txt)

  SYNC_CODE       Shared epoch / lineage key (e.g. 0x9A3B5C7D1E2F4G05)
  SILICON_REV     Silicon Core revision (e.g. S1)
  SPEC_VERSION    Optional: protocol package semver when published to tip

3. SEMVER FOR PROTOCOL_SPEC

  MAJOR   Wire break or resource rename without compat alias
  MINOR   New resources/verbs backward compatible
  PATCH   Clarifications, examples, non-breaking schema tighten

  Current draft: SPEC_VERSION = 0.2.0-draft
  (was 0.1.0-draft; bump recorded 2026-08-08 — OpenAPI Ball authority fields)

4. NEGOTIATION

  Client/station SHOULD send:
    sync_code, silicon_rev, spec_version (if known)
  Peer SHOULD reject or degrade with clear error if MAJOR mismatch.
  MINOR mismatch: newer peer SHOULD tolerate older clients where marked.

5. DECODER_RING_REV

  Separate label-meaning probe set revision (see TERM_REGISTRY_DECODER_RING.txt).
  Mind-meld failure is NOT always a wire failure — log as SEMANTIC_DRIFT.

6. FREEZE RULE

  Shipping a FEATURE that changes CORE_LAW field meanings is NON-CONFORMANT.
  Features PENDING_REVIEW until Catcher/Root accepts.
