Every workflow should end with a proof artifact.

Patchr proof cards turn agent runs into portable, inspectable records that can be cited, embedded, reviewed, escalated — or imported into external decision ledgers and governance systems.

Proof layer

Shareable evidence artifact

Proof cards are compact, citeable records for operators, reviewers, and external agents. They summarize evidence status, confidence, open questions, and restraint guidance.

Proof-to-decision portability

A proof card that travels with the decision.

Proof cards are not Patchr-internal artifacts. They are portable records designed to be cited across agents, systems, and time — including external decision ledgers that track choices and rationale across your organization.

Stable cite ref

Every proof card carries a permanent cite ref in the format patchr:proofCard:{id}#v1 — dereferenceable via API, embeddable in any document, stable across time.

Decision ledger portability

Operator Decision Log proof cards include a citeRef pointing to the full decision record — selected option, rejected paths, and rationale — importable by Decionis-style governance systems.

Cross-agent citations

A2A and MCP agents can dereference a cite ref to retrieve the proof context of any prior workflow run — no shared state, no duplicate audit logic.

External ledger interoperability

Works with Decionis-style decision ledgers.

The operatorDecisionLog template outputs a proof card with a citeRef in the patchr:decisionLog:{id}#v1 format. This maps directly to a portable ledger entry that governance platforms can import — full decision context, rejected paths, evidence hashes, and confidence, without re-running the workflow.
