notepad-write-guard: - The hook was created by create-tool-guard-hooks but tool-execute-before never invoked it, so the guard was inert. - It also only matched .sisyphus/notepads, missing the current .omo/notepads layout introduced by the workspace migration. - Add the dispatch call alongside writeExistingFileGuard, and extend NOTEPAD_ROOTS to cover both paths via normalize() + sep. New integration test pins the wire and the .omo block; the existing unit test now asserts both paths. start-work session-plan-affinity: - PLAN_PATH_PATTERN only matched .sisyphus/plans, so sessions referring to plans under .omo/plans returned null and start-work missed the current session's own plan. - Extend the regex to .(sisyphus|omo)/plans and add findPrometheusPlans in packages/boulder-state to scan both directories during the transition. New regression test pins .omo/plans matching; legacy .sisyphus/plans coverage preserved.
