Caersyn Trace - Evidence Infrastructure
Caersyn Trace turns system activity, decisions, approvals, refusals, and tool use into traceable evidence. Receipts, sealed proof bundles and verifiable records carry evidence across trust boundaries.
01 — The problem
AI agents call tools. Validators pass and fail. Approvals and refusals fire inside automated workflows that no person watches end to end. When someone asks “what happened, and can you prove it?” a file of logs is the answer from the system under question.
Trace moves selected system activity from source-controlled records into evidence that can be carried and verified outside the environment that produced it.
02 - The proof flow
One pipeline, end to end. Each stage produces an artifact the next one binds to. The finished record is a single chain of ordered execution evidence, not a folder of files - the same path, stage for stage, as the whitepaper.
Something consequential happens inside the host system.
activityThe host emits it, structured, from a strong control point.
event.emittedTrace records it in sequence under your namespace.
trace.orderedThe ordered evidence is sealed, creating the reference against which the recorded history can be verified.
segment.sealedA machine-readable handle, pointing back to the sealed record.
receipt.issuedReceipt, manifest and segment evidence, packaged for export.
bundle.sealedAn outside party checks it beyond the source system. Altered proof fails verification.
verify.pass ✓03 - What Caersyn Trace records
Caersyn Trace is built for selected events around actions, controls and decisions. The pilot begins by choosing those points within one workflow.
You choose which events in the workflow need to be recorded and emit them to Caersyn Trace as they happen. The resulting event history is ordered and cryptographically bound into the Trace record.
Proof boundary: Caersyn Trace proves integrity, ordering and verification status of the recorded event history. It does not prove source-system truth, payload accuracy, legal or business correctness, operational completeness or external-world truth.
04 — Why it matters
When an auditor, regulator or court asks why an automated action occurred, the answer should come from preserved evidence rather than memory, interpretation or internal assertion.
Receipts and proof bundles allow execution evidence to leave the source system without losing verifiability, so counterparties, reviewers and external institutions can check it independently.
When something goes wrong, the evidentiary record already exists. Replayable execution history reduces reconstruction from fragmented forensics to ordered review.
Approvals, controls, refusals and policy decisions are preserved as part of the same execution record as actions, turning governance from declared process into verifiable history.
Organizations, systems and reviewers do not need to rely on internal dashboards or unsupported claims when the underlying evidence can travel and be verified outside the environment that produced it.
05 — Use cases
Caersyn Trace runs alongside the existing stack, recording selected events at the points where stronger evidence is required.
Tool calls, plan steps, approvals, validator outcomes and refusals preserved as replayable, sealed, reviewable evidence.
UC·02Workflows that pay, provision, sign, grant, escalate, or refuse with verifiable evidence for each consequential step.
UC·03Lift selected OpenInference and existing telemetry signals into ordered, tamper-evident evidence without rebuilding the surrounding system.
UC·04Build steps, artifact hashes, validator results, approvals, and sign-offs bound into a verifiable release history.
UC·05Preserve evidence that a control existed, triggered and held at the recorded point of execution.
UC·06Evidence shaped for examiners: human-readable receipts on top of machine-verifiable proof.
Who the pilot is for
Caersyn Trace pilots are best suited to organisations where system activity may later need to survive review, dispute, audit, customer scrutiny or downstream reliance.
06 - Alpha pilot
Paid Alpha pilots take selected events from one real workflow into a sealed, externally verifiable record, with a focused Proof-of-Record deliverable.
What the pilot provides
Selected events from one workflow are recorded inside a hosted Trace namespace and preserved as ordered execution evidence.
The recorded evidence is packaged into human-readable receipts and a sealed proof bundle that can be carried beyond the source workflow.
The pilot demonstrates that exported proof material can be checked outside the source system, showing both when recorded evidence verifies and when altered, incomplete or invalid proof material fails verification.
