Purchase contract:
- unpaid POST returns 402 PAYMENT_REQUIRED with quote_id
- paid retry reuses the same POST with PAYMENT-SIGNATURE plus quote_id
- successful delivery returns order_id, job_id, receipt_token, and the decision artifact
- order, job, events, receipt, and lineage readback remain part of the public commercial loop
- Market Event artifacts are not order authority; actionable Market Event artifacts route agents to hyperliquid-fillshield before execution

Canonical top-level artifact envelope:
- artifact_version
- product_family
- product_id
- decision_state
- next_action
- hard_blocker
- reason_one_line
- expires_at
- recheck_after_ms
- confidence
- max_executable_notional_usd
- evidence_refs
- non_guarantees
- payload

Decision semantics:
- APPROVE: the artifact can advance to its next guarded step
- DEFER: rerun after the stated recheck timing or after fresh evidence arrives
- REJECT: do not act until new facts exist

Next-action semantics:
- SUBMIT_ORDER: FillShield says the current order may proceed within its TTL and size band
- RUN_FILLSHIELD: Market Event says route a concrete order intent to FillShield first
- RECHECK: rerun later
- WAIT: wait for missing or stale evidence to clear
- IGNORE: do not act on the current opportunity

Fail-closed contract:
- stale market evidence, missing official facts, missing source confirmation, unsupported policy, or degraded runtime must not become approval
- if truth is unavailable, the artifact returns blockers instead of pretending to be actionable

Compatibility service ids remain callable only where discovery marks them callable:
- hyperliquid-execute-guard -> hyperliquid-fillshield

FillShield note:
- hyperliquid-fillshield is the execution-control SKU
- shield.preflight_order remains the preferred MCP tool name
- run_hyperliquid_fillshield remains the compatibility MCP alias
