PRISM v2.9.1 released

[Ronkupper]

PRISM v2.9.1 is released — a framework-body consistency PATCH over v2.9.0. No behavior change, no capability added or removed; lint_catalog_version stays 3.

📦 Release: https://github.com/Ronkupper/PRISM/releases/tag/v2.9.1

Highlights

• Mobile-guide rename completed (E.5 → MO-5). §17 subsections E.1–E.4 are now MO-1–MO-4 (they had collided by label with Appendix E), and the stale (E.N) operator-hint references in §3.1 / §13 now point at MO-N.
• Cross-references corrected. The §4.9 M4 cross-ref resolves to M4's anchor (was pointing at M5's); the §1.3 roadmap and §8 parked-ideas citations are restored to DD.§9 and DD.§13.3.
• Named-reference hardening. Discrete anchors for SP-2 / SP-3 / SP-9; the dual §{…} namespace-resolution contract is documented in the citation conventions; the probe.* mis-wrap on P2.1 is dropped.
• M2 (Version Drift) clarified — operator-ratified. A Master carrying a framework stamp older than the running session is explicitly not drift: by PRISM's SemVer contract the running framework is a behavior-preserving superset, so orchestration proceeds (no halt). The reverse case (a newer framework stamp) stays out of scope.
• Counts & self-naming. SP-15's corollary count corrected (two → four); residual v2.0 self-naming in the scope/overview prose → v2.9.1.

The plugins/prism Skill is the deterministic projection of PRISM.md and has been re-projected to match. Gates green: named-reference linter (0 errors), cross-file linter, lens-version match (0.12).

• Version-pinned snapshot: PRISM_v2_9_1.md (byte-identical to PRISM.md at the tag).
• Surface-drift map: Appendix D (v1.x → v2) in PRISM.md.
• Design provenance: https://github.com/Ronkupper/PRISM/tree/v2.9.1/design
