rdmsm4x-changelog-20260831-1716-rdworkbench-mcp-retirement

Verified RDWorkbench MCP already absent on the canonical Mac and preserved Tyrell; added a host-local completion manifest plus canonical handoff and fleet records.

Scope and files changed

• Host: rdmsm4x; task: TASK-20260831-16.
• /Users/richh/Library/Application Support/MCPFleetRemoval/backups/20260831-1703/manifest.json — no config files required changes.
• /Users/richh/dev/_handoff/rdworkbench-mcp-removal/ — tested transformer, tests, report, and changelogs.
• Canonical ticket and HTML exports for TASK-20260831-16 under /Users/richh/dev/issues/, /Users/richh/Desktop/issues/tickets/, and /Users/richh/dev/sites/dev.ecs0.net/wiki/issues/.
• Canonical changelog archive under /Users/richh/dev/LLM/Claude/changelogs/.

Commands and verification

• Ran transformer dry-run/apply(no-op)/second dry-run, fresh Codex/Claude/agy listings, manifest/mode checks, alternate/project MCP searches, and process inspection.
• Final: RDWorkbench absent; Tyrell preserved; zero config changes; second pass zero; no matching process.

Backup and undo

• Manifest: /Users/richh/Library/Application Support/MCPFleetRemoval/backups/20260831-1703/manifest.json.
• No host config backup was needed because no registration existed and no config file changed.

Outstanding owner actions

• Apple Notes entry is pending because this host was changed through an SSH/background session; run zsh ~/scripts/notes_changelog.zsh <this-file> from Terminal.app on rdmsm4x.
