Planner self-improvement — auto-reported quality bugs

The home for bugs the Motir planner files about its own quality — the self-improving loop (Story 7.6). These are not build-plan work items; they are runtime-captured planner/agent flaws, filed into MOTIR/PROD via the service-auth route (MOTIR-1450) so the team can triage + fix the planner.

• Inward loop (MOTIR-965) — a planning mistake captured mid-plan becomes a kind: bug.
• Outward loop (MOTIR-967) — a sanitized cross-tenant Motir-caused failure becomes a kind: bug.
• Engine tool (MOTIR-1438) — the REPLAN action's log_planning_bug files one.

Where auto-filed bugs land

Under MOTIR-1465, the home story below — never at the project root, and not directly under this epic. Production reaches it by the literal key MOTIR-1465; once MOTIR-2201 ships, the drift-proof @planner-bug-home marker resolves to the same story by its exact title, project-wide.

The bugs already sitting directly under this epic are hand-filed planning bugs, not loop output.

This epic's title is the ensure_planner_bug_home migration's join key (PLANNER_BUG_HOME_EPIC_TITLE), so keep it in sync with that SQL literal — but it is no longer a resolution input for the filer.
