# Read the five gates on a Core digest

`product.gates`

Returns design review, infosec, SIT, UAT and go-live for the Product's sandbox Core, or the sandbox or live Core coreDigest names. A gate is required when the tenant wrote an approval policy under its key, `core.gate.<gate>`, in this environment, and its state comes from the approvals product.gate.submit opened on that digest, a signed one first, else the newest: open while it waits, signed once every step approved, rejected or returned by a decider, unsubmitted when none waits. Each gate names its policy version, the approval, its steps and every decision. SIT and UAT also name the SHA-256 of the Tests document the stored check outcome renders into. Nothing is stored beside the approvals: a new digest has no approvals, so every gate on it reads unsubmitted.

`GET /v1/products/{productId}/gates`

Principal `api_key`. Idempotency `not_required`. Environment `sandbox`.

## Errors

| Code | HTTP | Cause |
| --- | --- | --- |
| `approval_rejected` | 403 | A person rejected the call or returned it to the maker, so it never runs. |
| `approval_required` | 202 | The call waits for decisions: an agent's call over its grant waits on its delegator, and a program action under `requires approval` waits on distinct people other than the maker. |
| `environment_mismatch` | 403 | The session was issued for sandbox or live and the request targets the other environment. |
| `internal_error` | 500 | Hyperscale hit an unexpected server-side condition and hid internal implementation details from this audience. |
| `invalid_request` | 400 | The request does not match the API reference. |
| `method_not_allowed` | 405 | The route exists, but not for the request's HTTP method. |
| `missing_required_permission` | 403 | The signed-in member's current role does not grant the permission required for this operation. |
| `missing_required_product_capability` | 403 | The Product was created without a capability required by this operation. |
| `missing_required_scope` | 403 | The credential is valid but does not grant one or more operation scopes. |
| `not_found` | 404 | No Hyperscale route matched the requested path and method. |
| `oauth_client_not_admitted` | 403 | The bearer is an OAuth client token, and this operation does not admit the oauth2_client principal. |
| `operation_not_allowed` | 403 | The credential authenticated, but the operation is outside the allowlist its Product's composition produced. The message names the operation and the capability that would admit it. |
| `rate_limited` | 429 | The credential sent more than its limit in the current 60-second window: 600 requests per API key or session, 1,200 per IP address. Every response carries `x-ratelimit-limit`, `x-ratelimit-remaining` and `x-ratelimit-reset` (Unix seconds). |
| `resource_not_found` | 404 | The requested resource does not exist in the credential's visible scope. |
| `resource_reader_unavailable` | 503 | A generated read model could not serve the request at this moment. |
| `state_conflict` | 409 | The operation conflicts with the current durable state of the resource. |
| `tenant_mismatch` | 403 | The request mixed tenant-owned identifiers across tenant boundaries. |
| `tenant_not_found` | 404 | The credential resolved to a tenant Hyperscale cannot find. |
| `unauthorized` | 403 | The request did not include a valid Hyperscale bearer credential for this environment. |
| `agent_token_expired` | 401 | The agent token is real, but its grant ended. A grant lasts 30 days, or 7 days unused. `details.expiresAt` holds the date in ISO 8601 and `details.agentName` names the agent. |
| `agent_token_replaced` | 401 | The account owner ran `hyperscale agent setup` again for this agent, which replaced this token with a newer one. `details.agentName` names the agent and `details.replacedAt` holds the date. |
| `core_digest_unknown` | 404 | A gate signs one Core of the Product: its current sandbox Core or its live Core. coreDigest names neither. details.sandboxCoreDigest and details.liveCoreDigest name the two it accepts. |
| `device_login_expired` | 401 | The bearer is the account owner's own device login from `hyperscale auth login`, not an agent token. Its access token lasts an hour and the CLI refreshes it; the login itself ends after 30 days, or 7 days unused. `details.expiresAt` holds when it ended in ISO 8601. |
| `invalid_credentials` | 401 | Hyperscale could not accept the account or credential request. Signup, login, and bearer authentication use one 401 for every case they reject, so the response exposes no credential-specific reason or registered-email verdict. The single exception is a key that is real but homed in the other environment: because the presented secret already matched a stored key, the message names the mismatch instead of leaving a working credential looking unknown. A bearer that matched nothing gets text that fits its prefix (an agent token, a refresh token, a personal access token, a session or no Hyperscale token at all), which says only what the caller sent, never whether a credential like it exists. |
| `key_revoked` | 401 | The Product API key exists, but it was revoked. `details.revokedAt` holds the date. |
| `product_not_found` | 404 | No Product matches the `productId` in this tenant and environment, or a resource the request names belongs to a different Product than the API key's. A missing, foreign or ambiguous resource binding also reports this code. |
| `session_expired` | 401 | The session behind this request has ended. A console session ends 30 days after sign-in, or after 12 hours with no request. An admin or customer session ends 24 hours after sign-in, or after 15 minutes with no request. A personal access token ends at the `expiresAt` set when it was created. |
| `session_required` | 401 | This operation needs a person signed in through the browser or the `hyperscale` CLI. A Product API key cannot call it. The request carried no session, or its token matched no live session. |
| `session_revoked` | 401 | The session or personal access token behind this request was ended before its expiry. Sign-out, `user.session.revoke`, a password reset, a role change, removal from the team, user suspension and `personal_access_token.revoke` all end sessions. |
| `tenant_status_forbidden` | 409 | The company is suspended or closed, so every credential bound to it is refused, reads included. `details.tenantId` names the company. |
