Cognous Replay Bundle

Rebuild what happened from the records, without running it again.

A portable reconstruction format, importer, validator and CLI for agent-run evidence. Reconstruction Bundle 0.2.0 imports exact supported producer revisions while keeping legacy formats and historical provenance distinct.

The problem
Logs disagree, and stories fill the gaps

Records from authorization, execution and recovery can conflict or omit facts. A retrospective success story is easy to write and hard to check.

With Replay Bundle
One connected, honest reconstruction

Proposals, decisions, attempts, observations and source lineage in one bundle, with uncertainty and missing information left visible.

What it provides
Producer imports

exact supported Control Plane and executor combinations; unknown revisions are rejected, not guessed.

Identity continuity

proposal, decision and effect identity preserved, with attempt namespaces kept separate.

Recovery history

unknown acknowledgements, rejected or null observations and evidence-only recovery lineage retained.

Loss and completeness

declared coverage and missing information, without claiming the effect completed.

Portable review

validate, summarize, redact and sign exports; HMAC export integrity is separate from production key management.

In the refund workflow

After a bounded refund attempt, the importer consumes the actual Control Plane and executor records. It keeps whether the destination was observed applied, absent, partial or unresolved, and which source supplied each fact. Evidence Pack and ODES exporters then derive review material without rerunning the action or rewriting the originals.

Try it

Import the records from one reference run and check how an unresolved outcome is represented in the bundle.

What it does not claim

Reconstruction is non-effecting. It does not re-evaluate policy, renew authorization, repeat an effect or independently verify delivery. Completeness is not destination finality, and a valid digest or HMAC is not institutional authority.
