rdmpw3265m-changelog-20260903-0228-xentropy-local-skill-canonicalization

Updated the existing xentropy-local agent skill to use only this Mac's canonical XEntropy app/CLI and to reject archived, rollback, recovery, source, and handoff copies as runnable tools.

• Scope: rdmpw3265m only; no credential or internal-auth material copied.
• File changed: ~/.Codex/skills/xentropy-local/SKILL.md (the case-insensitive ~/.codex path resolves to the same file).
• New SHA-256: 0949be9cc07eeb668cf7771339f93e69230f41471e47a00f221153b6e4f5229a.
• Commands: exact old/new hash gate, atomic owner-file install, and post-install hash check.
• Verification: canonical and lowercase paths have the exact new hash.
• Backup: prior skill hash 1b4c9014fd731dcb1775a1c558b27ca37b9e0877d917057e63cedb3a23961c2c is retained under ~/.agent-coordination/recovery/xentropy-local-skill/20260903/.
• Undo: reinstall the named prior skill only after verifying its retained hash; do not alter XEntropy app, catalog, Keychain, or local-auth state.
• Outstanding: Apple Notes publication requires this host's foreground Aqua session.
