Quarterly Agent Test Evidence Composer

Composes a quarterly agent testing-evidence pack: test-suite identity and digest, per-test receipts with an honest deterministic/estimated determinism class, pass rate, and a regression comparison chained to the prior quarter's pack digest. A declared prior-pack digest that does not match the caller-supplied prior record is flagged as a broken chain rather than silently accepted.

Scope
This is an evidence FORMAT, not a certification claim. Output is cited as "prepared for AIUC-1 technical testing evidence," never "AIUC-certified." Pin aiuc_version to the catalog text in force at build time; a later catalog revision is a data re-pin, not a rebuild.
Determinism class
Only deterministic or estimated are ever written to the artifact. A seeded-stochastic class does not exist yet in the OCG standard: any other value on an input test record is coerced to estimated and flagged, never passed through.

Copy this paragraph into Claude, OpenClaw, or any MCP-aware agent to run this exact tool, with this sample, and verify the artifact.

Run the AINumbers MCP tool `build_agent_test_evidence`. Task: Compose a quarterly agent testing-evidence pack: test-suite identity and digest, per-test receipts with an honest determinism class, pass rate, and a regression comparison chained to the prior quarter's pack digest.
Call it with arguments: {"policy_parameters":{"quarter":"2026-Q1","aiuc_version":"2026-Q1","suite":{"suite_id":"agent-e2e-suite","suite_version":"3.4.0","suite_digest":"sha256:1111111111111111111111111111111111111111111111111111111111111111"},"tests":[{"test_id":"t1","determinism_class":"deterministic","status":"pass","receipt_digest":"sha256:2222222222222222222222222222222222222222222222222222222222222222"},{"test_id":"t2","determinism_class":"deterministic","status":"pass","receipt_digest":"sha256:3333333333333333333333333333333333333333333333333333333333333333"},{"test_id":"t3","determinism_class":"estimated","status":"pass","prng":{"algorithm":"xoshiro256**","seed":"42","draws":10000}}],"prior_quarter":null,"declared_prior_pack_digest":null}}
Verify before trusting: call `verify_execution_hash` on mcp.ainumbers.co (https://mcp.ainumbers.co/mcp) with the parameter `claimed_hash` set to the returned `execution_hash`, passing the full artifact the run returned (the object containing `policy_parameters` + `output_payload` + `execution_hash`; equivalently `policy_parameters` + `output_payload` with `claimed_hash`), not the bare hash string.
Return the ledger link https://ledger.ainumbers.co/ so a human can re-verify without contacting us.
