no behaviour change: a pure move of items and tests into new modules, plus
visibility edits (pub(crate)) and path updates in sibling modules that named
crate-root items. same routes, same OpenAPI, 561 tests before and after.
why: #5470, new features stop landing in one 6.4k-line file by default.
files outside swarm-controller/src: docs/agent-lifecycle/agent-roster.md,
swarm-ui JobsPage.tsx and AgentsPage.tsx, nix/host-modules/swarm-controller.nix
and swarm-grafana.nix hold comments that named main.rs for items that moved.
The agent's state/AGENTS.md stays the truth and its harness the only
writer. The harness mirrors the file into a new `agents-md` KV bucket,
and swarm-controller serves that copy, so a read works while the agent is
stopped. An edit is a unified diff plus the revision it was made against,
sent over the agent's existing control subject; the harness refuses a
stale base, applies the diff with `git apply --check` then `git apply` to
a temp copy, and writes the file only when both pass. Fixes#5519.
Files:
- swarm-queue-client/src/agents_md.rs, lib.rs: the bucket name and
subject, the mirror value, the `ApplyAgentsMd` control command and its
reply. `AgentControl` loses `Copy` because the new variant carries text.
- hive-agent/src/swarm_agents_md.rs, main.rs: the mirror task (start,
10 s re-read, immediate republish after an edit) and the apply.
- hive-agent/src/swarm_input.rs: the control loop answers both commands.
- hive-agent/src/claude_md_watch.rs: its AGENTS.md path is shared.
- hive-agent/Cargo.toml, Cargo.lock: sha1 for the git blob id (already in
the lock), tempfile moves from dev to runtime for the apply directory.
- swarm-controller/src/agents_md.rs, main.rs: the bucket reader and
GET/PUT /api/agents/{name}/agents-md; test AppState literals get the
new field.
- swarm-controller/src/agent_control.rs: the sink hands back raw reply
bytes, so each command decodes its own reply type.
- swarm-controller-api/src/agents_md.rs: the route bodies, shared with
swarmctl.
- swarmctl/src/agents_md.rs, main.rs: `swarmctl agent agents-md get|apply`.
- nix/host-modules/swarm-nats.nix, nix/module-eval/nats-authelia.nix: the
agent's publish grant on its own `$KV.agents-md.<agent>` key.
git needs no new package: agent containers enable programs.git, and the
harness unit's PATH includes /run/current-system/sw.
A separate $SWARM.control.<agent> subject carries commands, apart from
the text subject. swarm-controller exposes POST /api/agents/{name}/cancel
as a NATS request; the harness answers whether a turn was actually
stopped, through the same cancel path as the dashboard button. The agent
credential gets subscribe on its control subject and allow_responses to
answer; only the controller may publish there.
