The live pair was replaced with two renames, key then cert. A run
stopped between them (timeout, container stop, power loss) left a new
key beside the old cert, and every later run logged in with that pair,
so the agent could not re-pull until its container restarted.
Each pair now goes into a fresh directory under
/run/hive-agent-bao-identity, and `current`, a symlink to it, is
replaced by one rename. Wherever a run stops, `current` names one whole
pair; the next run removes whatever a stopped run left. Consumers read
`current/cert` and `current/key` through the same read-only options and
still re-read them on every login.
The script test covers a swap stopped at each of its link and rename
steps: the live pair is always one whole pair, and the next run puts
the new one live.

swarm-controller re-issues an agent's store leaf at half its validity, but
the running container kept presenting the copy its hive delivered at
start, so a re-issued leaf reached the agent only on its next restart.
hive-agent-bao-identity now seeds a live copy of the pair in its own
runtime directory from the delivered credentials, and re-runs every 10
minutes: it logs in with the live leaf, reads its own
swarm/agents/<agent>/bao-mtls (a read render_agent already grants), and
when the leaf changed, logs in with the new pair and swaps it in only if
the store accepts it.
Every unit in the container that logs in to the store presents the live
pair: hive-agent (queue-identity.nix), hive-matrix-daemon,
hive-subagent-daemon, hive-agent-forge-token, hive-agent-forge-accounts
and hive-agent-github-token. They keep loading the server CA as a
credential. The long-running daemons are ordered after the refresher so
the live pair exists when they start.
It renews only while the held leaf is still valid: the login that reads
the new leaf is made with the current one.

A claude agent with useApiKey gets ANTHROPIC_API_KEY through
backendEnvironmentFile, but only the harness unit loaded that file;
hive-subagent-daemon loaded it for ACP agents alone. The daemon's nested
claude inherits the daemon's environment (hive-claude adds to it, never
clears it), and an api-key agent has no OAuth session in ~/.claude, so
its claude subagents started with no credentials.
hive-subagent-daemon now loads backendEnvironmentFile when the agent is
ACP (unchanged) or has useApiKey set. Module-eval covers the api-key
claude arm; the existing claude arm (file set, useApiKey unset) still
asserts no EnvironmentFile.
Closes#5088
The subagent daemon gets the agent's store identity on every agent with a
store, whatever its runtime. The case pinned only the two ACP arms; it now
covers the claude runtime too, and checks BAO_CLIENT_CERT/KEY as well.
An agent's subagent daemon publishes each subagent's output as terminal
rows on `$SWARM.term.<agent>.sub.<subagent>`, as the agent, into a
per-agent stream it creates itself; swarm-controller lists an agent's
subagents from that stream's subjects and relays one subagent's rows as
SSE; the swarm UI lists them under the agent's terminal preview and
reuses AgentTermPreview, full-screen tab included, with no input.
- swarm-nats.nix: the agent token may also publish
`$SWARM.term.{agent}.sub.>` and `$JS.API.STREAM.CREATE|INFO` on
`term-sub-{agent}`, and nothing else of JetStream. A module-eval arm
pins the agent-token grant as an exact list.
- mcp.nix: hive-subagent-daemon loads the agent's store identity
(`hive-agent-bao-cert/-key/-server-ca`, the ones hive-agent loads)
whenever the agent has a store, not only on the opencode preset. The
agent's own queue secret lives in the store, so this is the credential
the harness connects with.
- hive-subagent-mcp: `swarm_term` reads the agent's queue secret under
that identity, connects with the agent token, opens or creates
`term-sub-<agent>` (max_age 24h), and publishes classified rows from
the sink every subagent line already passes through. The sink only
queues (bounded, drop-and-count); a missing store, refused credential,
failed stream create or failed publish is a log line.
- The stream-json classifier (`stream_enrich`) and the `TermMsg` row
types plus `fit` move from the hive-agent binary into hive-sh4re, so
the subagent daemon publishes the rows AgentTermPreview already
renders. hive-agent keeps its LiveEvent classifier on top.
- swarm-controller: `GET /api/agents/{name}/subagents` and
`GET /api/agents/{name}/subagents/{subagent}/term/stream`.
- docs/swarm: what the UI shows and what the queue carries.
Closes#4827
An opencode ACP agent got its provider API key only from the hand-placed
backendEnvironmentFile. It now also reads it from the swarm secret store
at swarm/agents/<agent>/acp-provider, field api_key, under its own
certificate, and sets it in the spawned ACP agent's environment only.
Nothing is written to disk.
Precedence: a value already in the process environment (the env file)
wins and the store is not asked. Otherwise the stored key is used when
present. With no store, nothing stored, or a failed read, the agent is
spawned without the key as before, and one line is logged without the
value.
The variable name comes from the existing per-agent option
acp.opencode.provider.apiKeyEnv, exported as HIVE_ACP_API_KEY_ENV on the
harness only for the opencode preset. Other ACP commands are unchanged.
The read lives in hive-runtime, where the ACP child is spawned, so both
hive-agent and hive-subagent-daemon use it. The subagent daemon unit
gets the key name and, when the agent has a store, the agent's store
identity (the same credentials queue-identity.nix gives the harness).
No new option or setting. Closes#4841.
The subagent daemon now reads the parent agent's runtime at startup
(`hive_runtime::RuntimeSpec`, from the harness's `HIVE_RUNTIME` /
`HIVE_ACP_*`, which `mcp.nix` forwards onto its unit). On claude
nothing changes. On ACP, each run drives an `AcpRuntime` whose session
id is kept per name under the harness dir: `start` archives the old one,
`continue` loads it (and fails when none is recorded), `interrupt` sends
`session/cancel`, a role goes in front of the first prompt, and
permission requests get the answers a claude subagent's tool list
gives. The unit loads `backendEnvironmentFile` on ACP only, so the
agent can authenticate.
The end-of-turn handling moves out of the claude loop into `after_turn`
unchanged, so both loops share it.
