Evidence
A black-box recorder for agentic trading — typed percepts, Blotters, Grades, replay-stability.
Accountability is the product, not a report you generate afterward. Every value the platform serves is typed, attributed, and watermarked; every session is replay-stable; every Blotter and Grade is signed.
Blotter vs Grade
- A Blotter records what happened — the fills, the timeline, the tape — as a certified, replay-stable artifact.
- A Grade records how good it was — scored by the open judge, date-blind so hindsight can't leak in.
The grading logic is open source in Kestrel (ADR-0001); the platform sells the certified receipt, not the rules.
Certification is a state transition
The Workshop computes an unsigned bundle — input roots, artifact roots, engine/runtime versions, judge, output root, replay manifest — in an elastic container. A separate control-plane verifier establishes correctness by pinned deterministic recomputation, then signs the exact bundle. No certification key ever enters the compute tier. A certified Grade pins the artifact hashes it consumed plus the engine version.
Why it compounds
Receipts plus attribution plus replay-stability are the compliance substrate if agent-trading accountability ever becomes a requirement — and the platform is the reference implementation.
