Resilience

Crash, reconcile, restart — without duplicate effects

A governance system that is correct only while nothing goes wrong is not a governance system. The interesting cases are the crash between commit and acknowledgement, the outcome nobody can determine, and the restart that replays a ledger.

The conditions exercised

Sustained load

A deterministic workload run long enough that ordering, contention and queueing effects appear rather than being designed away by a short test.

Replay storms

Previously valid requests re-sent in volume, checking that no second effect is produced for any of them.

Concurrent approvals

Multiple approvers acting on the same held request at the same moment, where exactly one consumption may win.

Process kills at documented windows

The process is killed after commit and after ledger write — the two windows where a duplicate effect would be possible — and recovery is checked from both.

Undeterminable outcomes

An effect whose real-world result cannot be established is recorded as unknown. It is never converted into a failure or a no-effect to make a report clean.

Policy change under activity

The active policy changes while requests are in flight, and each request is graded against the policy actually in force at its own dispatch.

Verdicts

Recovery without duplicate effects

Candidate

Processes killed before an effect, during dispatch, and between the execution commit and its ledger append all recover to a correct state. Executed actions stay executed, consumed approvals stay consumed, budget spend is preserved, and no restart produces a duplicate effect.

Limitation · Candidate, not proven: this passes its own gate on a development profile. Acceptance requires the full profile on a controlled machine, which has not been run.

Unknown outcomes stay unknown

Proven

When a request was transmitted but the answer never arrived, the system records the outcome as unresolved and retains the budget. It does not retry blindly and it does not convert an unknown into a failure to make the state tidy. Reconciliation then determines what actually happened.

Evidence protection blocks new execution

Proven

Where evidence protection is required, a failure of the witness that attests the evidence chain blocks new protected dispatch rather than letting execution continue unwitnessed. Reconciling work that may already have had an effect is never blocked, because refusing to reconcile would leave a real-world action in an unknown state to protect a log.

Why this reads Candidate

Durable recovery is built and passes its own acceptance gate, but that gate was written by the same party as the system. It has not been independently accepted, so it is Candidate rather than Proven. That distinction is the point of publishing verdicts at all.
