# law serve decision record 0.1

Append-only host record. `recordHash` covers the canonical bytes excluding `recordHash` and timing; `executionReceipt` carries its own receipt hash. Hash verification is performed by the journal reader.

## Versions

## `RefusalOutcome`

Type: `object`.
Required: `kind`, `error`.

| name | type-or-$ref | description |
|---|---|---|
| `kind` | `"refusal"` | — |
| `error` | `object` | — |
| `body` | `object` | Optional, additive: the refusal envelope exactly as the service answered it, present when the engine or preparation supplied its own body — a typed request refusal {"error": …} or the separate {"hostError": …} channel. Absent for the host's own refusals, whose envelope is {"error": {code, message}}. Replay must reproduce it verbatim. |
