The overview keeps the store invariant, the mTLS exception and the minter/reader/renewal contract. The table of every credential and the operating notes (forge token checks, re-creating agents, revoking a queue credential, store login retries) move unchanged to credentials-reference.md, and the links that asked where a credential lives point there.

# Credentials: the per-secret reference
|
|
|
|
Every credential in the swarm's secret store, in one table: who mints it, who
|
|
reads it, and whether it renews on its own. The overview and the rules a
|
|
credential follows are in [`credentials.md`](credentials.md); this page is
|
|
the detail, so it changes whenever someone adds a credential or moves its minting.
|
|
[`secrets.md`](secrets.md) maps the files that exist on disk today.
|
|
|
|
In the table, **automatic re-mint** is something replacing the stored value
|
|
without an operator. **Automatic re-pull** is the reader picking up a replaced
|
|
value without a restart. ✅ means it happens today, ❌ means it doesn't, and
|
|
the rest of the cell says how.

## Operating notes
|
|
|
|
The name `main` belongs to the swarm's own homeserver account, which the
|
|
controller mints, so the controller rejects any account you link under it.
|
|
|
|
`swarm-controller` checks every forge token itself: it looks at every agent
|
|
that has a store identity at start and every five minutes. For any whose
|
|
stored token is missing or stale it creates the forge user if there isn't one,
|
|
then mints the token. To check one agent now:
|
|
|
|
```sh
|
|
swarmctl agent mint-forge-token <agent>
|
|
```
|
|
|
|
An agent without a store identity gets no swarm token and keeps using the
|
|
`forge-token` file in its state dir, if it has one; re-create it with
|
|
`swarmctl agent create` to give it one. The swarm leaves an agent it already
|
|
declares as it is. For an agent with no declaration, such as one only its hive
|
|
knows about, `agent create` declares it `paused`; set it `up` from its card in
|
|
the swarm UI.
|
|
|
|
⚠️ **Re-create existing agents before deploying a hive-side change that makes a
|
|
container require a credential it may not have.** A container whose store
|
|
identity is absent doesn't start, so create the identities first, setting any
|
|
newly paused agent `up` as above.
|
|
|
|
**Revoking an agent's queue credential.** Declaring an agent `destroyed` —
|
|
`PUT /api/hives/{hive}/agents/{agent}/state` — deletes
|
|
`swarm/agents/<agent>/queue` and every version it held. An open queue
|
|
connection closes within an hour. An agent recreated under the same name gets a
|
|
fresh secret. It leaves the agent's mTLS leaf alone. If the store refuses the
|
|
delete, `swarm-controller` logs an `error` naming the agent and the teardown
|
|
continues; declare the agent destroyed again to re-run the revocation.
|
|
|
|
A failed store login retries every 30 seconds for a day. When a later attempt
|
|
lands a changed value, the service that loaded it restarts. If the fetch unit
|
|
can't compare file times it logs `cannot compare the mtime of <path> … —
|
|
leaving <unit> as it is` at `err`, and the service keeps the old value until
|
|
the next timer tick.
