| the swarm controller's forge token | the forge's `forgejo-swarm-controller-account`, in-container, once | the swarm secret store at `swarm/controller/swarm-controller/forge/token`, written by the mint under the forge publisher's leaf, which the forge container loads as a credential; the controller holds it in memory only. `/var/lib/forgejo/swarm-controller-token-name` in the forge container holds its name, the minter's record that it has minted | nothing to place beyond the controller's store leaf. A forge host without the store needs the publisher's leaf placed (`deploy.bao.forgePublisherClientCertFile`) |
|
||||
| the swarm controller's Grafana token | `swarm-bao-grafana-controller-token.service`, **on the host that runs Grafana**, as Grafana's built-in admin over its socket: it creates the `swarm-controller` service account as a Viewer (and sets it back to Viewer on every run), mints a token for it and writes it to the swarm secret store at `swarm/controller/swarm-controller/grafana/token` under Grafana's leaf. Re-run every ten minutes: it keeps a stored token Grafana accepts, and replaces one Grafana refuses with 401 (or a missing one), deleting every other token of that account first | the swarm secret store only; the controller reads it for `GET /api/alerts` and holds it in memory, re-reading the store once when Grafana answers 401 | nothing to place: Grafana's leaf is already required to run Grafana. Until the unit has run, `/api/alerts` answers 503 naming the empty path |
|
||||
| an agent's API-key environment (`ANTHROPIC_API_KEY`, `ANTHROPIC_BASE_URL`, an ACP provider key) | `hive-agent-backend-env.service`, in the agent's container, on an agent with a store that uses `useApiKey` or the `acp` runtime. When the store holds nothing at `swarm/agents/<agent>/backend-env` and `backendEnvironmentFile` is a non-empty file, it creates the leaf with the file's exact bytes and `-cas=0`, under the agent's own leaf, which may create that path and not update it. It never rotates a value and never rewrites or deletes the file. To set or replace a key, use **set the API-key environment** in the swarm UI (`PUT /api/hives/{hive}/agents/{agent}/backend-env`): `swarm-controller` overwrites the leaf with its own grant, and the store's value then wins over the file. Its **remove** (`DELETE` on the same path) deletes the leaf, and an agent whose file has content then creates it from that file again | the swarm secret store at that path; the unit writes it to `/run/hive-agent-backend-env/env` (tmpfs, `0600`, root), and `hive-agent` and `hive-subagent-daemon` load that after `backendEnvironmentFile` as `EnvironmentFile=` | the same unit, same path. A variable in the store wins over the same one in the file. With the store down at a start, the file alone carries the agent, as it did before the store held a copy; with an older hive build the agent ignores the leaf and keeps reading the file |
|
||||
| an agent's proxy settings (`HTTPS_PROXY`, `HTTP_PROXY`, `NO_PROXY`, the credential in the proxy URL) | `hive-agent-proxy-credential.service`, in the agent's container, as the agent user, at start and every 10 minutes: it reads `swarm/agents/<agent>/proxy-credential` under the agent's own leaf and builds the file from it. It writes nothing while the path holds nothing or the hive's facts name no squid | `/run/hive-agent-proxy-credential/proxy.env` (tmpfs, `0600`, the agent user); the harness, its bash tool, the subagents, the MCP servers and the pollers load it as `EnvironmentFile=-` and read it when they start | With no credential, or on a hive that writes no `HIVE_SQUID_PROXY` and `HIVE_EGRESS_NO_PROXY` fact, nothing writes the file and a unit has no proxy variable and reaches the internet directly. A failed read keeps the file already in place. A unit started before the file appeared goes direct until its next start. The credential is also in the environment of every process those units start, so `env` in the agent's shell prints it |
|
||||
| an agent's claude login (`.credentials.json`) | `swarm-claude-login.service`, in its container, when an operator completes `claude auth login` from the agent's card in the swarm UI; it stores the file as a new version at `swarm/agents/<agent>/claude-credentials` under its own leaf, which may create and update that path and read nothing under an agent | the swarm secret store at that path; the agent's `hive-agent` reads it under the agent's own leaf every 30 seconds while it waits for a login and writes it to `~/.claude/.credentials.json` | the same read, co-located or not; nothing for an operator to place beyond the agent's store leaf. When the store's copy and the agent's differ the KV version decides: the agent installs only a version newer than the last it installed (`claude-credentials-version` under the harness dir), because claude rotates the refresh token in its own copy and the stored one goes stale. The agent ignores a stale or equal version, and a relogin writes a newer one — [claude-login.md](claude-login.md) |

| the queue responder's copy of its OIDC secret | the responder reads it out of the swarm secret store itself as it starts, under its own leaf, and again when authelia refuses it | the daemon's memory only; never on disk | same read, wherever authelia runs. Nothing for an operator to place beyond the responder's store leaf (`deploy.nats.authBaoClientCertFile`) |
|
||||
| the queue container's journal forwarder's copy of the queue's OIDC secret | `swarm-journal-forwarder-oidc.service` inside the `swarm-nats` container reads it out of the swarm secret store under the responder's store leaf, and again every 10 minutes | `/run/swarm-journal-forwarder-oidc/client-secret` on the container's tmpfs, root `0400`, never on persistent disk; `LoadCredential` hands it to the collector | same unit, same path. After a reboot the collector restarts until the file exists, then resumes from its saved journal cursor. Nothing for an operator to place beyond the responder's store leaf (`deploy.nats.authBaoClientCertFile`) |
