I read this as a full Task 7 remediation and immutable-candidate delivery - I’ll pin the current state, trace the approved plan and audit findings, reproduce failures first, then make only Task 7 changes and verify every required restart/fault/type/UX boundary.


The pinned digest has drifted before my first edit: only `gateway/platforms/telegram.py` changed (`44a44e…` -> `4c4999…`), while the other pinned files remain unchanged. I’m pinning these actual starting bytes and treating the in-worktree callback-isolation change as pre-existing dirty work; I’ll avoid overwriting it and continue from the current state.


I’ve completed the architecture trace. The smallest sound path is: add a durable authority-root witness (so deletion is distinguishable from one-time migration), add an append-only edit intention before any child-ledger mutation, make worker transitions carry opaque claim CAS, and expose receipt reconciliation as a callback operation. I’m starting with failing-first regressions for those exact boundaries, then applying the persistence changes.


A second Task 7 remediation process is actively writing the same two files (timestamps changed during my patch application), which produced a concrete duplicate-state conflict. I’m pausing edits until that writer quiesces, then I’ll re-read and reconcile the combined bytes rather than overwrite either implementation.

previous_status: running

reason: Serialize Task 7 ownership; overlapping writer caused candidate drift and syntax collisions.
