Runtime history is bounded observation, not a replay log. Saved interrupted jobs are evidence and are never automatically dispatched again. +`JobStore.recover(transcript)` compares each saved call and result with the +checkpoint. A returned job whose exact evidence is already present reconciles +silently; the absence of an old display notice is not a recovery event. Missing +calls/results and queued receipts are repaired, conflicting results fail closed, +and newly uncertain outcomes are reported. The returned `recovered` list contains +jobs with actual restoration/change or newly reported uncertainty, not every +job loaded from the ledger. + +Recovery notices retain their stable job/call identities and service provenance. +Their optional `metadata.recovery` object contains `version: 1`, `job_id`, +`call_id`, `status`, `outcome`, and `reason` (`restored_evidence`, +`changed_evidence`, or `uncertain_outcome`) for host presentation. The private +ledger remembers which result's uncertainty was announced, so compaction that +removes only the notice stays quiet. That fingerprint is not a checkpoint +acknowledgment: restoring an older checkpoint or losing tool evidence still +requires reconciliation, even if the same result was announced earlier. + Live responses carry generation and delivered-input identities, separate from provisional assistant content and native steering acceptance.
