Failure recovery
Recovery must preserve the exact approved operation and prevent duplicate or mismatched execution. Availability does not justify bypassing authorization controls.
Public recovery principles
| Condition | Required safety boundary |
|---|---|
| Signing participation is insufficient | Keep affected authorization closed; do not silently lower the threshold or replace participants |
| Execution outcome is uncertain | Reconcile provider or chain state before resubmitting; do not assume either success or failure |
| Evidence delivery is pending | Preserve records and disclose the pending state; do not claim independent anchoring |
| Service or host fails | Preserve and validate recoverable state before reopening affected work |
| An identity may be compromised | Contain the affected access, preserve evidence and use an approved recovery process |
The controlled 3-of-5 profile uses a fixed active participant set. Recovery descriptions do not establish automatic participant replacement or independent multi-operator availability.
Conditions for reopening
The responsible team must verify request and evidence integrity, reconcile external outcomes, confirm authorized participants and access, and record who approved resumption. Unresolved safety conditions keep the affected execution path closed.
A backup alone is not proof that recovery will succeed. Whole-host recovery, independently administered backup storage and production incident response need deployment-specific acceptance.
Operational instructions
Detailed backup, restore, retry and recovery procedures are version- and environment-specific. They are delivered to approved operators through a restricted channel and must not be inferred from this overview.
Do not combine participant secrets into a recovery bundle or share private credentials in support messages. For a suspected vulnerability, use Responsible disclosure. For operational material, see Source and documentation access.
