 # FlyBot — Roadmap
 
-#2483 controller loss: verify local/Docker worker shutdown and same-generation lease reconciliation; legacy records need actual saved exit evidence. Chief baseline choice reuses task.run continuation; verify actual checkout SHA, stale-choice correction, draft protection and PR ancestry separately.
-
-#2483 restart: cover saved state reload through Chief choice and actual pool re-dispatch, including historical blocked claims, preserved drafts and exit uncertainty. No fixed recovery role, automatic Task acceptance or live deployment.
-
-#2483 resource Git parity: verify current Project/Attempt/resource/cwd and private Git metadata before granting Dev its clone `.git`; validate actual SDK mutations and read-only denial separately from live resource acceptance.
-
-#2483 adds typed dispatch waits and bounded Chief input continuation through existing notifications; source/fixture completion remains distinct from the current OpenToday instance.
-
-#2483 proceeds through storage failure handling, dispatch/input-receipt diagnosis, resource Git capability and explicit baseline/restart recovery. Historical log times are not current health evidence; no live migration or automatic Task acceptance.
-
-#2413: recover saved merge-to-Chief handoff with idempotent requests and bounded backfill; expose delivery separately from Chief outcome and Task acceptance.
-
-
-#2378: enable explicit Actions reads/download hosts and retrievable exact-SHA test artifacts; real installed-App/private-repository acceptance remains separate.
-
-#2393: precise Run/receipt/snapshot feedback and no replay of applied Task decisions; no automatic role/human routing or new scheduler.
-
-
-#2375: retire proven exited responsibility before fresh integration admission; source/isolated tests remain separate from live recovery.
-
-#2377: continue the verified original seed or explicitly integrate a new baseline; no silent draft reset or cancelled Attempt revival.

+exit remains held; actual profile/App/SDK/OpenToday recovery requires its own evidence.
+Canonical Harness, delivery, workspace and Chief contracts remain binding; no fixed
+workflow, automatic acceptance, credential changes or live deployment is authorized.
