# Verify a signed Safe House decision

`GET /decisions/{decision_id}/verify`

## Request

- Base URL: `https://api.mnemom.ai/v1`
- URL: `https://api.mnemom.ai/v1/decisions/{decision_id}/verify`
- Auth: none required

Independently verify a persisted canonical SafeHouseDecision's Ed25519 signature and per-(agent, run) hash chain (MNE-1381 / C14). Reconstructs the decision from its row and delegates to the shared verifySafeHouseDecision core: a tampered covered field or prev_hash breaks the chain recompute; a forged/absent-key signature breaks the Ed25519 check — both surface as verified:false (a successful answer, not an error). Public endpoint, no authentication required.

## Path parameters

- `decision_id` string, required

## Response `200`

## Other responses

- `404`: Resource not found
- `429`: Rate-limit exceeded. The global per-IP limiter (100 requests/minute, applied to every `/v1/*` route) rejected this request. Back off until the window resets — `Retry-After` carries the cooldown in seconds and `X-RateLimit-Reset` the absolute reset time.
- `500`: Server error — request was well-formed but the server failed to fulfill it. Typically a downstream dependency (DB / RPC / external API) returned an unexpected error.
- `503`: An upstream dependency is currently unavailable. The request was not processed; retry after the cooldown window.
