Then hops through steps concise and nice.
New keys are made, old keys retire,
Error rows match what classes require.

| # Router keys: operator and requester runbook | ||
|
|
||
| A router key (`mar_live_<...>`) is what a person, tool or service presents to `<router-url>/v1/**`. | ||
| This page is the practical lifecycle: mint, hand over, rotate, revoke, and what a key holder sees | ||
| when a request fails. The contract behind it (storage, verification, scope) is | ||
| [`docs/idea/04-api-keys-and-access.md`](idea/04-api-keys-and-access.md). Every value below is a | ||
| placeholder. | ||
|
|
||
| Keys are stored encrypted and are retrievable from the console at any time. Nothing here is | ||
| "shown once". | ||
|
|
||
| ## Operator | ||
|
|
||
| ### Mint | ||
|
|
||
| Console: **Keys**, then **Mint key**. API: `POST /api/admin/keys` on the admin plane (session cookie | ||
| plus CSRF token, or `ADMIN_API_TOKEN`). | ||
|
|
||
| 1. **Name** the key `<owner>/<tool>`. The name is free text and the convention is only | ||
| documentation, but it is how you find the key later. | ||
| 2. Fill the attribution fields, which feed usage reporting and change nothing about | ||
| authentication: | ||
| - `owner`: who the key was issued to. A slug: lowercase `a-z`, `0-9`, `.`, `_`, `-`, starting | ||
| with a letter or digit, at most 64 characters. The API answers `400` on anything else. | ||
| - `ownerKind`: `person` or `service`. | ||
| - `tool`: what runs on the key. Same slug rule as `owner`. | ||
| - `purpose`: free text, up to 500 characters. | ||
| 3. **Scope** the key to a pool rather than `all`. The three forms are `all`, one or more pools, or | ||
| an explicit account list. Leaving `scope` out of a create request means `all`. Scope is | ||
| intersected with pool membership and never widened. | ||
| 4. Optionally set a **rate limit**: `requests` per `windowSeconds`. It is enforced per replica, in | ||
| memory, so N replicas together admit up to N times the ceiling. Over it the key gets `429` | ||
| `key_rate_limited`. | ||
| 5. Optionally set an expiry (`expiresAt`). Keys have no expiry by default. | ||
|
|
||
| An attribution field can be changed later with **Edit** (`PATCH /api/admin/keys/:id`); `null` | ||
| clears it. Editing never changes the key's value. Like a revoke, an edit (a narrower scope, a new | ||
| rate limit) takes effect at once on the replica that handled it and on the others within | ||
| `KEY_CACHE_TTL_SECONDS`. | ||
|
|
||
| ### Client setup | ||
|
|
||
| Send the key as `Authorization: Bearer mar_live_<...>` or as `x-api-key: mar_live_<...>`. Never send | ||
| both with different values: the request is refused. The per-client recipes are in | ||
| [`clients.md`](clients.md). The console's **Point your tool at it** panel shows the same recipes | ||
| filled in; do not copy those prefilled values into tickets or chat. | ||
|
|
||
| ### Rotate | ||
|
|
||
| There is no rotate endpoint, by design (`updateKeyBody` in | ||
| `apps/api/src/services/keys/schemas.ts`): a key you can re-read does not need one. | ||
|
|
||
| This is planned rotation, where the old key stays live until the client has moved. For a leaked or | ||
| lost key, use [Leaked or lost key](#leaked-or-lost-key) instead. | ||
|
|
||
| 1. On the old key's row, choose **Mint successor**. The mint form opens prefilled with the | ||
| attribution, scope and rate limit. The value is never copied and the expiry is not inherited: | ||
| set it again if the old key had one. | ||
| 2. Give the successor its own name, such as `<owner>/<tool>-2` or a date suffix. Names are unique | ||
| and the old key keeps its name, revoked or not, until it is purged; reusing it answers `409`. | ||
| Mint it, then give the new value to the client and swap it in. | ||
| 3. Watch the **Last used** column: the old key's should stop advancing and the new key's should | ||
| start. Last-used is stamped on a verified cache miss, so it moves about once per | ||
| `KEY_CACHE_TTL_SECONDS` per replica (default 60), not on every request. | ||
| 4. **Revoke** the old key. | ||
|
|
||
| Rotate when someone leaves or a tool is retired. There is no scheduled rotation: a key does not | ||
| expire unless you set one. | ||
|
|
||
| ### Leaked or lost key | ||
|
|
||
| When a device is lost, a key is pasted somewhere public, or a leak is suspected, revoke first and | ||
| accept that the client stops working until it gets a successor. Waiting for **Last used** to settle | ||
| does not work here: whoever holds the leaked key keeps it advancing. | ||
|
|
||
| 1. **Revoke** the key now. | ||
| 2. On a deployment with more than one replica, restart or roll the other replicas: that empties | ||
| their key caches immediately. Otherwise they keep accepting the key for up to | ||
| `KEY_CACHE_TTL_SECONDS`. | ||
| 3. **Mint successor**, under a new name, and hand it over privately. | ||
|
|
||
| ### Revoke | ||
|
|
||
| Console: **Revoke** on the key's row. API: `POST /api/admin/keys/:id/revoke`. | ||
|
|
||
| - The next request on the replica that handled the revoke gets `401` `key_revoked`. | ||
| - Other replicas keep accepting the key for up to `KEY_CACHE_TTL_SECONDS` (default 60 seconds). That | ||
| setting is the bound; read it from your own environment. Restarting or rolling the other replicas | ||
| drops their caches at once. Lowering the setting needs a restart too, and only shortens future | ||
| windows, at a database round trip per uncached verification. | ||
| - In-flight requests finish. A stream is not torn down. | ||
| - Revocation is one-way. A revoked key is never reactivated. | ||
| - A revoked key keeps its row, scope and usage attribution until `RETENTION_REVOKED_KEYS_DAYS` | ||
| (default 30) after revocation. Then it is purged, and its usage rows keep an id that no longer | ||
| resolves to a name, owner or tool. | ||
|
|
||
| ### Hand back is revoke | ||
|
|
||
| When a key is handed back, revoke it. Do not use **Delete** (`DELETE /api/admin/keys/:id`): a hard | ||
| delete removes the row at once, so its past usage stops resolving to a name, owner or tool | ||
| immediately. | ||
|
|
||
| ## Requester | ||
|
|
||
| 1. **Ask** the operator for a key. Say who it is for (the `owner`), whether that is a person or a | ||
| service, which tool will use it (the `tool`), and what it is for (the `purpose`). Ask for a | ||
| scope that covers only what you need. | ||
| 2. **Receive** it from the operator over a private channel. The value is `mar_live_<...>`; treat it | ||
| as a password. Do not commit it, paste it into a ticket or a chat room, or put it in a shared | ||
| shell history. | ||
| 3. **Configure** your tool with `<router-url>` as the base URL and the key as its API key. See | ||
| [`clients.md`](clients.md) for the recipe and a verification command. | ||
| 4. **Rotate** when the operator asks: take the successor key, swap it in, and tell the operator so | ||
| they can revoke the old one. If a device is lost or the key leaks, tell the operator at once; | ||
| they revoke it first, and you wait for the successor. | ||
| 5. **Hand back** by telling the operator you no longer need it. They revoke it. | ||
|
|
||
| ## Errors a key holder sees | ||
|
|
||
| This is the key, scope and capacity subset of what the data plane can return, not every status. The | ||
| error class table is in | ||
| [`packages/core/README.md`](../packages/core/README.md#errors--each-class-fixes-its-code-and-status-at-declaration-not-at-the-call-site). | ||
|
|
||
| | Status | Meaning | | ||
| |---|---| | ||
| | 401 `key_revoked` | revoked, unknown, expired, malformed or missing key, or Bearer and `x-api-key` disagree | | ||
| | 402 `credits_exhausted` | an account is out of credits. Do not retry: it stays this way until the operator tops it up | | ||
| | 403 `scope_violation` | nothing is in scope. Do not retry: ask the operator for a wider scope | | ||
| | 429 `key_rate_limited` / `quota_exhausted` | the key's rate limit, or accounts cooling (clock-recoverable); with `Retry-After` | | ||
| | 503 `key_verification_unavailable` | transient; retry after `Retry-After: 1` | | ||
| | 503 `no_healthy_account` | nothing in scope can serve this request; read the message (below). No `Retry-After` | | ||
|
|
||
| For `no_healthy_account`, the message names the cause: | ||
|
|
||
| - A model no in-scope account serves: a client change. Pick another model, or ask the operator for | ||
| a wider scope. | ||
| - A missing endpoint, or a misconfigured account: an operator fix. | ||
| - "every attempt failed": may clear on retry. Back off (exponential, bounded) rather than retry at | ||
| once. | ||
| - Anything else, including an account that is disabled or needs re-auth: the operator. | ||
|
|
||
| A revoked key and a never-existed key look the same (`401`). If you were working an hour ago, | ||
| assume the key was revoked or rotated and ask the operator. | ||
|
|
||
| ## Where your usage shows | ||
|
|
||
| Today, on the console's **Keys** page: | ||
|
|
||
| - the per-key usage and cost columns, for the selected window; | ||
| - the **Last used** column; | ||
| - the owner and tool filters, which narrow the loaded list in the browser (exact match, | ||
| combinable). Scripts use `GET /api/admin/keys?owner=<owner>&tool=<tool>` with the same rule; a | ||
| value that is not a valid slug answers `400` there. | ||
|
|
||
| The Usage page broken down by owner and tool, and a weekly report, extend this section when they | ||
| land. |

…s, 09 aligned - A leaver's own key and a retired tool's key are handed back (revoked), not rotated; rotate only a still-needed key whose value a leaver saw. - Leaked-key step 2: roll every replica only when KEY_CACHE_TTL_SECONDS is longer than a roll; a roll drains in-flight requests up to SHUTDOWN_DRAIN_MS, then ends the rest, and resets per-key rate-limit windows. A single replica needs nothing. - 403 names a pool with no members; the 503 verification retry is bounded. - docs/idea/09: the KEY_CACHE_TTL_SECONDS row says edits invalidate locally too; the troubleshooting row matches KEYS.md instead of 'no faster path than lowering the TTL'. - The docs test also compares the set of codes, so a duplicated row cannot hide a missing one.

What
docs/KEYS.md: a generic runbook for router keys, with an operator section and a requester section. It is linked fromREADME.mdanddocs/idea/04-api-keys-and-access.md. Version 2.30.1.Closes #230. Part of #216.
Why
Keys now carry owner, kind, tool and purpose (#219). The team needs one written procedure for minting
<owner>/<tool>keys, rotating them without downtime, and revoking them, plus what each error a key holder sees means. The repo had no such doc.Changes
