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.
The module is a rename (97% similar); everything else in the diff follows
from the move:
- stored_secret.rs: private `chain()` helper, the 8-line copy of the queue
crate's `chain` the module called as `crate::chain`; the queue crate's
public `chain` stays.
- stored_secret.rs: `Duration::from_mins(5)` in `MAX_REREAD_DELAY` is
unchanged moved code, not a new use.
- swarm-secret-client Cargo.toml: gains futures-util, tokio and tracing as
dependencies and tokio `test-util` plus tracing-subscriber as dev
dependencies; the module and its tests use them.
- swarm-queue-client Cargo.toml: drops futures-util and the tracing-subscriber
dev dependency, which only the moved module used; its tokio dev comment is
reworded to the tests that remain.
- Cargo.lock: the same dependency moves, nothing else.
- swarm-queue-client lib.rs: imports `swarm_secret_client::stored_secret`,
and its tests use a small local `Store` in place of the moved module's
test-only `Fake`, which is no longer reachable.
- callers (hive-c0re, swarm-builder, swarm-ci-metrics, swarm-claude-login,
swarm-controller, swarm-nats-auth, swarm-review-classifier): import path
only; no re-export is left behind.
The rustls provider install is process setup every swarm binary runs, and
swarm-secret-client depends on no other swarm crate, so a binary that only
needs the provider and the store no longer links the queue client.
- swarm-secret-client/src/lib.rs, Cargo.toml: the function, its test, a
`//!` line on why it lives there, and the rustls dependency; rustls
`ring` as a dev-dependency feature, so the test builds both providers as
the binaries do and fails if the install is dropped.
- swarm-queue-client/src/lib.rs, Cargo.toml: function and test removed;
`connect()` calls the secret client's; rustls dropped (no other use),
swarm-secret-client added.
- swarm-metrics-auth/Cargo.toml: drop swarm-queue-client, whose only use
was the provider; the binary no longer links async-nats.
- swarm-logs-auth, swarm-logs, swarm-metrics, swarm-ci-metrics Cargo.toml:
the dep comment no longer names the provider (they keep the dep for
agent_token / the OIDC mint).
- Cargo.toml: the rustls comment names the provider's new home.
- 14 call sites (hive-agent, hive-c0re, hive-subagent-mcp x2,
swarm-builder, swarm-ci-metrics, swarm-claude-login, swarm-controller,
swarm-logs-auth, swarm-logs, swarm-metrics-auth, swarm-metrics,
swarm-nats-auth, swarm-review-classifier): one-line path change.
- Cargo.lock: the dependency edges above.
The user JWT the callout issues carried no exp, so nats-server armed no
expiry timer and a connection kept its grant until the client dropped it:
a deleted or re-minted agent queue secret, a removed OIDC client or an
expired access token never reached a live connection.
Every issued user JWT now expires at the presented OIDC token's exp
(read from the introspection answer) or an hour after issue, whichever
is sooner; the agent queue-secret path has no exp of its own and gets
the hour. Every queue client reconnects through an auth callback that
re-reads or re-mints its credential, so the forced reconnect presents a
current one.
Fixes#5432
POST /api/agents takes an archetype the stored list holds, records it in
the new agent-archetype bucket, and queues no CreateRepo, AddRepoMember or
InitAgentConfigRepo for it. A destroy clears the key. Hives may read the
bucket.
Refs #5386
The agent read the operator-profiles bucket with a keys() listing, an
ordered consumer whose grant (STREAM.INFO, CONSUMER.CREATE) and flow-control
reply had never run against a permissioned queue. The controller now writes
the whole list as one JSON array under one key, only when it changed, and
the agent reads it with one DIRECT.GET the way agent_inference::read_own
reads its key. The agent grant shrinks to that one subject.
swarm-controller reads each member of authelia's operator group's forge
profile every five minutes and keeps one key per operator in the new
operator-profiles bucket. Every agent may list and read that bucket, and
hive-agent renders it into the system prompt at harness start, falling
back to today's prompt when the bucket is empty or doesn't answer within
five seconds.
Fixes#5383
A flake declares agent archetypes in its `hyperhiveArchetypes` output,
`<name> = { module; meta; }`. The hyperhive flake ships `reviewer`
(default permissions without `execution`).
swarm-builder answers `$SWARM.builder.archetypes` with the `meta` of
every archetype its own hyperhive source declares. swarm-controller asks
once the queue connects and every 10 minutes, checks each archetype as
`POST /api/agents` checks its settings, and stores the result in the
`agent-archetypes` KV bucket when it changed. `GET /api/archetypes`
serves it, and the create form's archetype select prefills permissions,
resource caps and inference from it.
The agent created is an ordinary agent with its own config repo; the
archetype's module is not applied yet.
Refs #5386
An agent's capabilities move from the hive's meta repo
(`meta/capabilities.json`, injected as `HIVE_CAPABILITIES`) into the
`capabilities` field of its key in a new `agent-permissions` KV bucket,
which swarm-controller alone writes.
- swarm-queue-client: `agent_permissions` (bucket, key, `AgentPermissions`,
direct-get read, the import subject and its wire types).
- swarm-controller: creates the bucket at start; `GET|PUT|DELETE
/api/agents/{name}/permissions` (deny_unknown_fields and unknown
capability ⇒ 422, duplicate ⇒ 400, agent must be declared by a hive);
answers each hive's one-shot import, writing a key only where there is
none and only for agents that hive's wanted state declares.
- swarmctl: `agent permissions get|set|clear`.
- swarm-nats-auth: a hive reads every key of the bucket and sends its
import on its own subject; the controller subscribes to the imports and
may answer them (`responses`).
- hive-c0re: reads each of its agents' keys every 30s into
/var/lib/hyperhive/swarm-agent-permissions.json and restarts an agent,
gracefully, when its capabilities change. Unset is the compiled-in
default (ruth: manage_root_agent; everyone else: none). A failed read
keeps the stored value. On first boot it seeds that file from
meta/capabilities.json, sends the grants to the controller, and deletes
the file once the controller answers.
Deleted: the capabilities.json reader/writer, `HIVE_CAPABILITIES` in the
rendered meta flake, ruth's capability seed, the capabilities half of the
permissions rebuild job (`PermPayload::Capabilities`/`Combined`), the
dashboard's capabilities table and `capabilities_changed` event, and the
now-unused `Capability::description`.
Part of #5170.
A new swarm service, `swarm-claude-login`, in its own container on the host
that sets `deploy.claude-login.enable` (defaulted on by `allSwarmServices`
where the host has the minter's store leaf, like the review classifier).
- swarm-ui: an agent card showing "login needed" gets a "log in" button.
Its dialog starts the login, shows the URL claude printed, and takes the
pasted code.
- swarm-controller: `POST/DELETE /api/agents/{name}/claude-login` and
`POST /api/agents/{name}/claude-login/code`, behind the swarm UI's
authelia-gated `/api/`, relay the steps to the minter as requests on
`$SWARM.claude-login.request`.
- swarm-claude-login: runs `claude auth login` over piped stdio with HOME
and CLAUDE_CONFIG_DIR in a per-login scratch dir, scrapes the first
https URL, writes the code to stdin, and stores the `.credentials.json`
at `swarm/agents/<agent>/claude-credentials` with a KV v2 write, a new
version over any earlier one. The scratch dir goes on every exit path; a
login waits 15 minutes for its code.
- hive-agent: while parked in `wait_for_login`, reads that leaf every 30 s
under the agent's own cert and installs it only when its KV version is
newer than the one recorded in `<harness>/claude-credentials-version`.
An equal or older version is never put back, because claude rotates the
refresh token and the stored copy is stale after the first refresh.
- swarm-secret-client: `claude_login` paths and `SecretStore::read_versioned`.
- Credentials: a `claude-login` store leaf minted by glue-bao-tls, a
`swarm-claude-login` policy (create/update on
`swarm/agents/+/claude-credentials`, read on its own queue client
secret), an authelia machine client, and a `--claude-login-client`
grant in the queue's auth-callout responder. The unit runs as a static
system user.
The hive's own web-UI login is unchanged.
Refs #5268
A separate $SWARM.control.<agent> subject carries commands, apart from
the text subject. swarm-controller exposes POST /api/agents/{name}/cancel
as a NATS request; the harness answers whether a turn was actually
stopped, through the same cancel path as the dashboard button. The agent
credential gets subscribe on its control subject and allow_responses to
answer; only the controller may publish there.
Refs #3803
The agent's turn-state header ($SWARM.agent-state.<agent>) gains
`needs_login`, set by hive-agent from its own LoginState, so the flag
reaches the swarm without hive-c0re (mara on #5268: "id prefer the agent
container sending the info it needs login without hive").
- swarm-queue-client: `agent_login::Login`, the shared wire type, beside
`agent_inference::Effective`. `needs_login: Option<bool>` with
`#[serde(default)]`: a header from an older agent decodes as `None`
(unknown), never as "needs login" or "logged in".
- hive-agent: the header publisher reads the shared LoginState cell.
Every writer of that cell emits a status on the bus afterwards, so a
login change goes out on the next rebuild, not the 60 s refresh.
- swarm-controller: `agent_login::Reported` follows every agent's header
and keeps the latest flag; `GET /api/agents/status` merges it into each
row as `needs_login` (null when unknown).
- swarm-ui: AgentCard shows a warning-tone "login needed" badge when the
row's `needs_login` is true.
Refs #5268
A new `swarm-builder` service, in its own container on the host that sets
`deploy.builder.enable` (defaulted on by `allSwarmServices` where the host
has the builder's store leaf, like the review classifier).
When an `agent-configs/<agent>` PR is opened, reopened or synchronized,
swarm-controller queues a `build_agent` jobq node. The node sets a
`swarm-builder` commit status to pending on the PR head, sends
`{agent, rev, pr}` to the builder over NATS request-reply
(`$SWARM.builder.build`), and writes success (store path), failure (last
line nix printed) or error (no builder / no reply) on the head. The node
fails when the build does, so the Jobs page matches the PR.
The builder builds nix/builder/check-flake's `check` with every input
overridden: hyperhive and nixpkgs to the host's own
`c0re.hyperhiveFlake`/`c0re.nixpkgsFlake` (what a hive there renders into
its meta flake), and the agent to the PR head on the forge. Evaluation is
pure and runs in the container; builds go to the host nix daemon as an
untrusted client. The private config repo is fetched with the token of a
new read-only `builder` forge account (in the `hives` team), which the
controller mints into `swarm/services/builder/forge/token`; git gets it
from a credential helper reading the child's environment, so it is in no
argument or URL.
Credentials: a `builder` store leaf minted by glue-bao-tls on the store
host, a `swarm-builder` reader policy (forge token + its own OIDC client
secret), an authelia machine client, and a `--builder-client` grant in the
queue's auth-callout responder. The controller gains a grant on the token
path and the secret publisher a deny on it.
This is the agent-config build check atlas scoped on #5081 (slice 3):
nothing is pushed to a cache, nothing is written to KV, and a red status
gates no deploy. The check composes agent-base + the config without the
values a hive adds (CA, docs, claude-code path, ports, input follows), so
it can disagree with a hive's own build.
The responder re-read its secret on any non-2xx introspection answer.
With the re-read backoff added in the previous commit, an IdP outage
(503s, 502s from nginx, 429s) made each re-read find the unchanged
secret, so the delay grew to minutes. A real 401 after the rotation
then landed inside that window, and the responder denied every new
NATS connect until it ran out.
`Answer::Refused` now carries the status. `OidcSecret::introspect`
re-reads only when `stored_secret::is_credential_refusal` says the
status is 400 or 401, the same predicate `ClientSecret::refused` uses on
the client path. Every other non-2xx is a denial with no re-read.
The client-path test for a 429 now runs the mint against a loopback
endpoint answering 429 and 503, instead of calling `refused()` directly.
swarm-queue-client's README no longer names `ClientSecret::Value`.
Part of #5017 (slice Q).
hive-c0re (`hive-<name>`), swarm-controller and swarm-review-classifier
read their queue client secret from the store once and held it as
`ClientSecret::Value` for the life of the process. After authelia
re-minted a secret and swarm-secret-publish stored the new one, every
later token mint presented the old value and was refused until the
daemon restarted.
`ClientSecret::Stored` replaces `Value`: a `StoredSecret` holds the
secret in memory with a caller-supplied read callback, so the crate
takes no store dependency. When the token endpoint answers 400 or 401,
`mint_token` (and its blocking sibling, used by the controller's OTLP
exporters) re-reads it and, if the store holds a different secret,
mints once more with it. One re-read runs at a time and is spawned so
it outlives a caller that gives up. A re-read that fails or finds the
refused value delays the next one, 5 s doubling to 5 min, so a secret
that stays wrong costs one store read per delay. Logs name the client
id and never the secret.
swarm-nats-auth's `oidc_secret` was the template; its re-read machinery
now sits on `StoredSecret`, so the tree has one copy. The responder
gains the same re-read backoff.
The controller keeps its `IDENTITY` OnceLock: it now holds a
`QueueConfig` whose secret is re-read, and the lazily built vcs-metrics
exporter reads the identity from it.
agent_renewal.rs's module doc said a re-minted agent queue secret only
reaches the agent at its next start; hive-agent reads the store on every
connection attempt after its first, so the doc now says that.
Part of #5017 (slice Q).
An agent's CPU and memory caps, set from the swarm. Keyed by the agent
alone, in a new `agent-limits` KV bucket that swarm-controller alone
writes, the same shape as `agent-inference` (#5034): mara on #4268,
"agents are not tied to a hive. dont tie the limits to the hive."
PUT {"cpu_quota": "400%", "memory_max": "8G"} every field optional,
replaces the stored value
GET the stored caps, {} when there are none
DELETE 204
PUT refuses an agent no hive's wanted state declares (as the inference
route does), unknown fields (422), zero and anything systemd does not take,
before the queue is asked, and stores memory in the spelling systemd takes
(8gb -> 8G). The hive hands these values to systemd verbatim.
The routes sit under /api/, behind the swarm UI vhost's authelia
subrequest like every sibling; the core-toggle module-eval case pins that
gate.
The bucket's reader on the hive comes in the next commit.
Contributes to #3865.
swarm-queue-client gains review_classifier: the try-out subject, the
request and reply that travel on it, and the deadlines both ends share.
The controller's reader grant may publish the subject; a client named
with --review-classifier-client may subscribe to it and its inbox, and
answers under NATS allow_responses (resp in the user JWT) within the
run deadline. Every other client id is still denied.
swarm-controller now creates `term-main-<agent>` for every live agent, in
the same one-minute pass and with the same config style as
`term-sub-<agent>` (#4897): subjects `$SWARM.term.<agent>` only, max_age
24h, max_bytes 64 MiB, discard Old, max_message_size from the queue's
max_payload. An existing stream is opened as it is. The agent keeps its
plain publish on `$SWARM.term.<agent>` and gets no JetStream subject.
`GET /api/agents/{name}/term/stream` creates an ephemeral push consumer on
that stream starting 100 rows back, so a swarm-ui terminal opens with
recent history and then follows new rows, in order, from one
subscription. Each SSE event carries the row's stream sequence as its id,
and a reconnect's Last-Event-ID resumes after it. Without the stream the
route falls back to the live core subscription it used before.
The stream is `term-main-<agent>`, not `term-<agent>`: an agent may be
named `sub-x`, whose `term-<agent>` would be agent `x`'s subagent stream.
Its one literal subject cannot match `$SWARM.term.<agent>.sub.>`, which
needs more tokens, so the two streams never overlap.
The reader gains `$JS.API.CONSUMER.CREATE.*.*.$SWARM.term.*`, the
extended create form whose last tokens are the consumer's filter. Checked
against nats-server 2.14.4, the trailing `*` also admits a literal `*` or
`>` filter, so a consumer under it reaches any terminal row, main or
subagent; those are rows the reader already subscribes to and reads with
`STREAM.MSG.GET.*`.
Closes#4826
Each agent now reports the model and effort it runs on, and where each
comes from (`swarm`, `agent_nix`, `local_file` or `default`), in its
turn-state header on `$SWARM.agent-state.<agent>`: `effort`,
`model_source` and `effort_source` join `model`. The shared
`swarm_queue_client::agent_inference::{Effective, Source}` types spell
those fields for both ends.
The Bus keeps a source next to the model and effort. `Bus::new` takes it
from the local fallback chain (`harness_state::local_model` /
`local_effort`, which now return the source with the value), a `/model`
or `/effort` pick sets `local_file`, and the swarm poller sets `swarm`
or, on a clear, the local chain's source. A swarm value equal to the one
the agent already runs is now applied once, so the source moves to
`swarm` and the header is republished; before, `next()` skipped it as
unchanged.
swarm-controller subscribes to every agent's header with the reader
grant it already holds for the state relay, and keeps the latest
inference fields per agent in memory (`inference::Reported`).
`GET /api/agents/{name}/inference` now answers
`{configured, effective}`, `effective` being `null` until the agent's
first header with these fields since the controller started.
`swarmctl agent inference get` prints both; `set` reads `configured`.
Refs #5034
hive-c0re publishes this hive's status to the swarm queue as the OIDC
client `hive-<name>`. Its secret came from
`deploy.hive-controller.statusPublish.clientSecretFile`, which defaulted
to authelia's minted file only on a host running both authelia and the
queue. Every other hive had no secret and never published, so the
controller showed it `never_reported`.
Now `swarm-secret-publish`, beside authelia, also copies each hive's
`hive-<name>` secret to `swarm/hives/<hive>/oidc/client`. Its policy
already allows `swarm/hives/*`. hive-c0re reads that path under the
hive's own store leaf, which the existing `swarm/hives/<hive>/*` grant
covers, and holds the value in memory.
The shared queue client no longer remembers a failed first connect for
the life of the process. A failed attempt is retried with a backoff
from 5s, doubling to a cap of 5 minutes; the dashboard banner stays up
until an attempt succeeds. The two status publishers wait for the
client instead of giving up on the first `None`, so a secret published
after boot is picked up without a restart.
Removed: the `statusPublish.clientSecretFile` option (both spellings,
now removed options with a message), its same-host default, its
LoadCredential, the assertion tying it to the other two coordinates,
and `swarm_queue_client::QueueConfig::from_env`, whose only caller was
this read. Publishing is now on wherever the queue URL and token
endpoint are set and the hive holds a store leaf.
Refs #5015
swarm-controller keeps each agent's inference settings in a new
`agent-inference` KV bucket, one key per agent, and is its only writer
(`GET`/`PUT`/`DELETE /api/agents/{name}/inference`; `swarmctl agent
inference get|set|clear`). Every field is optional. Each agent reads its
own key every 10 s through a direct-get grant on that key alone, and a
set `model` or `effort` replaces the Bus value, so the next turn runs on
it and the badge follows.
The swarm value is applied without persisting it: `Bus::set_model` and
`set_effort` are split into a persisting setter and a non-persisting
`apply_*`, and the poller uses the latter. Otherwise the swarm value
would overwrite `hyperhive-model`/`hyperhive-effort`, and clearing it, or
a restart, would no longer find the agent's own value. An unset field
changes nothing; a field cleared after being applied goes back to the
local value (`harness_state::local_model`/`local_effort`, the same
resolution `Bus::new` uses), read again at the clear.
`subagent_models` is validated, stored and shown by `get`; no agent
applies it yet.
Refs #5034
- swarm-controller webhook: regenerate the secret only when the file is
absent. Any other read error is returned with the path; the caller
already logs "webhook secret unavailable" and the endpoint answers 503.
Overwriting meant every registered hook kept the old secret and every
delivery failed HMAC, with nothing re-registering them.
- swarm-queue-client wanted: open_read_only/watch return Result; only
STREAM_NOT_FOUND on the bucket maps to None. hive-c0re's wanted pull
fails the DAG node with the cause instead of logging "nothing has been
declared"; the watch warns with the error chain.
- swarm-nats-auth: warn when the OIDC secret re-read task dies.
- swarm-controller forge: listing a repo's config PRs failing is warn,
not debug.
Closes#5056
No behaviour change. Casts replaced by try_from / Duration math; schedules.rs
reuses agent_renewal::unix_now; the five swarm-queue-client KV open-or-create
copies share one private kv::open_or_create.
The reader's subscribe allow-list spelled `$SWARM.term.*`,
`$SWARM.term.*.sub.*` and `$SWARM.agent-state.*` as literals, copies of
private prefixes in hive-agent and swarm-controller. A rename on either side
left the policy behind and the stream stopped with only a connection-level
server error.
swarm-queue-client now owns `term_subject`, `agent_state_subject` and their
`*_wildcard` forms, and `subagent_term::subject_wildcard`; hive-agent's
publishers, swarm-controller's relays and the policy all build from them.
Subjects are byte-identical.
A hive's queue credential and the swarm controller's could subscribe to
every subject in the swarm account, so a hive could read every other
hive's deploy requests and every agent's terminal, state, input and
request replies.
Their grants now carry a subscribe allow-list:
- a hive `hive-<h>`: `$SWARM.knowledge`, `$SWARM.deploy.<h>` and its
reply inbox `_INBOX.client.hive-<h>.>`
- the reader (swarm-controller): `$SWARM.term.*`, `$SWARM.term.*.sub.*`,
`$SWARM.agent-state.*` and its reply inbox
`_INBOX.client.<client-id>.>`
`swarm_queue_client::connect`, which hive-c0re and swarm-controller both
use, now connects with `_INBOX.client.<client-id>` as its inbox prefix,
the same shape agents got for their own credential. In async-nats 0.50
every request reply and every ordered consumer (the hive's wanted-state
watch, the controller's KV key listings) delivers under that prefix, so
the one inbox grant covers them all.
A hive or controller still on a build without the prefix has every
JetStream reply refused once the responder runs this policy, so the
clients need to be rebuilt before, or with, swarm-nats-auth.
Closes#4945
Docs (review on #4948): the harness's restart settings are not useful to
a reader, so the `Restart`/`RestartSec` bullet in docs/turn-loop and the
"30 seconds later, no start limit" wording in docs/swarm are removed.
What stays is the behaviour: the harness exits and comes back until the
queue accepts it.
Grant: with the harness's shared-client fallback gone, nothing presents
the hive's shared agent client (`hive-<hive>-agent`) to the queue;
swarm-logs uses that OIDC client over HTTP only. swarm-nats-auth now
refuses it outright instead of granting the configured
`$SWARM.term.{hive}.>` / `$SWARM.agent-state.{hive}.>` publish and its
`_INBOX.client.<id>.>` subscribe, so an agent holding it can no longer
publish as a sibling. The agent arm still runs before the hive arm, so
that id never falls through to its hive's grant.
Removed with it: the `--agent-publish-subject` flag and its two uses in
swarm-nats.nix, `Policy`'s agent subject list, and
swarm-queue-client's `client_inbox_prefix`. The module-eval now asserts
the flag is absent; the policy tests assert the refusal and that the
hive itself is still admitted.
An agent's harness connects to the swarm queue with the agent's own
credential or not at all. The first connect retries after 5s, doubling
(7 attempts, about five minutes), with a warning per failed attempt;
when every attempt fails the harness logs an error and exits 1. Missing
coordinates (HIVE_AGENT_NATS_URL, or the secret store's BAO_ADDR /
HIVE_AGENT_NAME / certificate) fail the boot outright.
Previously the first connect's outcome was memoized for the life of the
process: a store 403 or queue refusal at boot left the agent on the
hive's shared client, or disconnected, until someone restarted it, and
an agent with no queue coordinates ran on without one. Both paths are
gone, with the hive-scoped subjects that only the shared client used.
The harness unit now restarts after 30s instead of 2s, so a swarm-wide
outage doesn't restart every agent every 2s, and has no start limit, so
it keeps coming back however long the outage lasts.
The hive's shared client credential is still imported into the harness
unit for swarm-logs; the two HIVE_AGENT_OIDC_*_FILE variables that
pointed the harness at it are dropped, as is the unset
HIVE_AGENT_OIDC_CA_FILE override.
With the fallback gone, the pieces #4944 added only for it go too:
swarm_input's skip-on-shared-client branch and swarm-queue-client's
connect_with_inbox_prefix. swarm-nats-auth's grant for the hive's shared
agent client is unchanged.
Closes#4909
An agent's queue credential could subscribe to every subject in the swarm
account, so any agent could read every other agent's terminal, turn state,
operator input and request replies. Agents are the least trusted clients
on the queue (mara's ruling on #4901), so their grants now carry a
subscribe allow-list:
- an agent's own credential (the harness and its subagent daemon):
`_INBOX.agent.<agent>.>` and `$SWARM.input.<agent>`
- the hive's shared agent client: `_INBOX.client.<client-id>.>`
Hive and swarm-controller grants are unchanged (no `sub` claim, so still
every subject).
The clients connect with the matching inbox prefix, so the replies they
rely on still arrive: the icon write's JetStream ack and the schedule
DIRECT.GET. `connect_with_token` takes the agent name and sets the prefix
itself; the hive-shared fallback uses the new
`connect_with_inbox_prefix`.
The harness no longer subscribes to its input subject when it fell back
to the hive's shared client: that identity names no agent, so it cannot
be granted one agent's input without all of them. It logs that and
skips, the same as the schedule reader on that path.
Refs #4901
swarm-controller keeps every scheduled prompt (id, name, agents, body,
anchor, interval, paused) as one document under one key of a new
`schedule-definitions` KV bucket, so each change is a single
compare-and-set and a prompt exists for all of its agents or none. It
writes each agent's key of a new `agent-schedules` bucket as the prompts
naming that agent, without names or other agents, after every change and
on a one-minute reconcile pass. It is the only writer of both, behind
GET/POST /api/schedules and PATCH/DELETE /api/schedules/{id}.
`swarmctl schedule add|list|edit|pause|resume|rm` drives those routes over
the controller socket.
An agent's own queue credential is granted one more subject, the direct
get of its own key in `agent-schedules`. A KV watch is not granted: its
consumer create subject carries no key, so it would cover every agent's.
hive-agent's new schedule ticker reads that key every 10 seconds and fires
due slots as the same `schedule:<id>` todo hive-c0re's worker pushes. Fire
times are anchor + k*interval; the last fired slot per schedule id is kept
in the state db, so a body edit or list refresh never moves or refires a
slot, downtime fires the latest missed slot once, a restart refires
nothing, a one-shot fires once, and paused slots are skipped.

The agent view in the swarm UI gets a message box. The text reaches the
agent's harness straight from swarm-controller over the swarm queue and
becomes an inbox turn from the operator's authelia username. hive-c0re is
not in the path.
- gateway: `/api/` forwards authelia's `Remote-User`, replacing any the
client sent.
- swarm-controller: `POST /api/agents/{name}/input` takes that header as
the sender (401 without it) and sends `{from, body}` as a NATS request
on `$SWARM.input.<agent>`. No subscriber is a 503.
- swarm-nats-auth: the controller is granted publish on `$SWARM.input.*`;
no hive or agent grant names the family, so the harness can trust
`from`.
- hive-agent: a task subscribes to the agent's own input subject and
pushes each message into the serve loop's existing reminder channel,
renamed `local_msg_*` since it now carries both.
The harness does not reply to the request: no agent grant covers a reply
subject. The controller therefore answers 202 once the request times out
(2s) and 503 on the server's no-responders status.
Closes#4828
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
A config PR merged in the Forgejo UI changed nothing on the hive: the
hive's webhook ignores `closed`, its poll then cancels the dashboard
card, and `applied/main` stays where it was.
swarm-controller reads `merged`/`merge_commit_sha` off the
`pull_request` delivery it already receives for `agent-configs`, finds
the hive placing the agent by scanning every hive's wanted state (the
scan `declarations_elsewhere` already ran, factored out), and queues a
`TriggerDeploy` carrying the rev. Zero or several claimants deploy
nothing and log the claimants.
`DeployRequest` gains `rev: Option<String>` with `serde(default)`, so
rev-less payloads from either side keep decoding.
hive-c0re, given a rev for an agent it runs: a no-op when
`applied/main` already is the rev (a dashboard merge deploys its own
PR); otherwise it fetches the forge `main` with the core token,
requires the rev to descend from `applied/main` (the ancestry gate,
factored out of `run_deploy_merge_verify`), fast-forwards by CAS and
queues the usual relocking rebuild. No eval-verify on this path, per
mara (#4850 c90075). A refusal is commented on the PR that merged the
rev, found by commit.
swarm-controller's forge-objects pass converges every config repo's
`main` rule to merge whitelist `operators` + `core` and approval
whitelist `operators`. The hive's boot PATCH stops forcing
`enable_approvals_whitelist` off, so the two do not fight.
Refs #4850
hive-matrix-daemon now learns which external matrix accounts it has from
the swarm secret store, under the agent's own certificate, and the hive
push chain for matrix is gone.
The daemon lists swarm/agents/<agent>/matrix/ (the `list` its policy
grants on its own metadata subtree), reads each account's homeserver
from its credential, and brings the accounts up with their tokens from
the store. Every two minutes it lists again and exits with 75 when the
set of linked accounts changed; the unit restarts on 75 without counting
a failure. A listed name whose credential reads as absent is skipped and
logged once. At start it removes the matrix-token-<a> /
matrix-account-<a>.json pairs a hive delivered (a sidecar marks a pair
as delivered; a declared tokenFile keeps its token).
Removed: CredentialNotice and the $SWARM.credential.* subject and NATS
grant, the controller's publish and its queue precondition on the PUT
route, hive-c0re's credential subscription arm and workers/credential.rs,
priv_client::write_agent_matrix_token, hive-priv's WriteAgentMatrixToken
and its helpers, and the daemon's state-dir account discovery.
Kept: WriteAgentGithubToken and the external-forge path
(WriteAgentExtraForgeAccount, extra_forges.rs) are untouched, and a
declared matrixAccounts tokenFile is still read when the store has no
token for that account.
Refs #4348
The harness now reads swarm/agents/<agent>/queue from the store itself,
under the agent's own store certificate, and holds it in memory only.
It reads once before the first connect and again on every reconnect
attempt (async-nats `ConnectOptions::with_auth_callback`), so an agent
whose secret was re-minted reconnects with the new value instead of
being refused until the container restarts.
hive-agent-queue-credential.service, the /run file it wrote, and
HIVE_AGENT_QUEUE_AGENT_SECRET_FILE are gone; queue-identity.nix now
hands hive-agent.service the store address, its certificate paths and
the agent name.
A failed or empty read before the first connect still falls back to
the hive's shared client. Each read is bounded by a 10s timeout, and
retries wait out the existing reconnect backoff (500ms doubling, capped
at 60s).
Closes#4783
The controller's OIDC client secret (client `swarm-controller`, used for
the queue connection, the auth-bridge bearer and the OTLP push) came from
an operator-placed file, `deploy.swarm-controller.queue.clientSecretFile`,
handed in by `LoadCredential=`.
Now `swarm-secret-publish`, which already copies authelia's minted OIDC
secrets into the store, also publishes this one, to
`swarm/controller/swarm-controller/oidc/client`. That path sits under
`controller/`, which no hive's policy reads. The controller reads it once
at start with its existing store certificate and holds it in memory, as
`swarm_queue_client::ClientSecret::Value`. If the store is down, it
retries for about a minute and then fails the start, so `Restart=` tries
again.
Policy delta: the controller gets `read` on that leaf, and the publisher
gets `create`/`update` on that leaf.
Removed: the `queue.clientSecretFile` option (both spellings, now removed
options with a message), its singleHostSwarm default, the credential and
placeholder, and the path watcher plus its restart oneshot. A controller
without a store identity is now an eval error, because it has no other
way to get the secret.
The auth callout grants an agent that presents its own queue credential
one more subject, `$KV.agent-icons.<agent>`: its own key in the
agent-icons bucket and no other. The hive's shared agent client is
granted none of the bucket, since every agent on a hive presents it.
hive-agent writes `/etc/hyperhive/icon.svg`, the file its `GET /icon`
serves, to that key once per start, as a JetStream publish straight to
the subject (what `kv::Store::put` sends, minus the bucket lookup), so
the one subject is the whole grant. No icon deletes the key. A failed
write, including one that arrives before the bucket exists, is retried
with backoff until acked. An agent connected with the hive's shared
client publishes nothing.
swarm-controller creates the bucket as soon as its queue connection is
up, instead of on the first icon read, so an agent's write does not
wait for someone to look.
Measured against a local nats-server with a user allowed publish on
`$KV.agent-icons.atlas` only: the write to its own key is stored and
readable, a write to `$KV.agent-icons.argus` is refused (the ack times
out), the DEL marker makes the key read as absent, and a write before
the bucket exists fails with "no responders".
An agent is not fixed to a hive, so its icon cannot be resolved as
hive -> agent. This adds the swarm-level half: an `agent-icons` KV
bucket keyed by the agent name alone — no hive token, so an agent that
moves hives keeps its icon and one that is stopped still has one — and
`GET /api/agents/<name>/icon` on swarm-controller serving it
same-origin, like every other `/api/*` route swarm-ui calls.
404 is the "this agent has no icon" answer, the same contract the
per-agent harness's own `GET /icon` has for an unconfigured agent.
Until the agent-side publisher lands, that is every agent's answer:
the publisher runs inside the container and an agent's NATS grants are
hive-scoped, which cannot authorise a write to a single-token agent
key. The read side needs no grant change — the controller already
holds `$KV.*.>` and `$JS.API.DIRECT.GET.*.>`.
The response carries `Content-Security-Policy: sandbox` and `nosniff`:
the body is an operator-authored SVG served from this daemon's own
origin, and an SVG can carry script.
Hive-side icon serving is untouched.
Refs #4502
When the per-agent secret `queue-identity.nix` fetched is present, the
harness connects with `swarm-agent.<agent>.<secret>` as a static token
and publishes on `$SWARM.term.<agent>` and `$SWARM.agent-state.<agent>`.
When it is absent, or that first connect fails for any reason, a refusal
from a responder that does not verify agent tokens included, it connects
with the hive's shared OIDC client and publishes on the hive-scoped
subjects as before. Which one it took is logged once per connect.
`swarm_queue_client::connect_with_token` is the static-token connect: no
retry on the initial attempt, so the caller sees the refusal and can
fall back. Reconnects share the existing backoff, now a named function.
Closes#4630
`swarm_queue_client::agent_token::format_agent_token` / `parse_agent_token`
are the spelling an agent presents its own queue secret in,
`swarm-agent.<agent>.<secret>`, and the one the auth-callout responder
reads back. The prefix is what separates it from an OIDC access token,
which may itself contain `.`. Parsing distinguishes "not an agent token"
(no prefix) from "a malformed one"; the error names the problem and never
the value. The module is store-free, so the agent formats its token
without linking the secret-store client.
`swarm_secret_client::queue::AgentCredential` loses `hive`: an agent's
identity is not tied to a hive, and nothing reads the field. Objects
already in the store carry it and still decode, since unknown fields are
ignored; a test parses one. The controller stops writing it.
With the credential no longer naming a hive, and the agent's policy
naming none since #4762, nothing in the mint consumes one. `hive` goes
from `mint_and_verify`, from the `MintAgentIdentity` node, and from
`POST /api/agents/{name}/identity`, which now takes no body and no longer
checks a hive against the roster; a caller that still sends one is not
refused, the body is ignored. `swarmctl agent mint-identity` loses
`--hive`, so passing it is now a usage error.
rustls is built with both `ring` (async-nats's `ring` feature) and
`aws-lc-rs` (reqwest's `rustls` feature), so it cannot pick a
process-level default by itself. Since the queue started requiring TLS
(1d261b3f), async-nats builds its config with `ClientConfig::builder()`,
which panics without an installed default. The panic kills the async-nats
connector task, and every queue client (swarm-controller, hive-c0re, all
hive-agents) has sat in `Pending` since the 2026-09-25 23:04Z deploy.
Add `swarm_queue_client::install_crypto_provider()`, which installs
aws-lc-rs and ignores the "already installed" error. It is called first in
`main` of every binary that links async-nats: hive-agent, hive-c0re,
swarm-controller, swarm-nats-auth. `connect()` also calls it, so a new
binary that dials through this crate is covered without remembering to.
aws-lc-rs because reqwest already falls back to it when no default is
installed, so HTTPS in these processes keeps its current provider. The
other rustls users in the tree reach it only through reqwest, which never
panics here.
Closes#4738
The queue listened in plaintext on 4222, reached by bridge IP or loopback,
and nothing in-tree opened it to another hive. It now has a name, serves a
certificate for that name alone, and refuses clients that do not speak TLS.
- `swarm.nats.domain`, default `nats.<swarm.domain>`, a sibling name like
`swarm.bao.domain`. The queue host answers it via `gateway.localNames`;
every other hive resolves it through the operator's DNS, as for bao.
- `pki/roles/swarm-nats` allows that one name (bare domain, no subdomains,
IPs or localhost, server flag). A `swarm-nats` cert-auth role and policy
may only `update` `pki/issue/swarm-nats`, written by
`swarm-bao-nats-tls-policy`. The login leaf is minted by glue-bao-tls and
paired by glue-nats-bao-identity. `deploy.bao.natsCommonName` is reserved
as a hive name.
- `swarm-bao-nats-tls` issues the leaf into a directory bound read-only into
the container, restarts nats when it rotates, and re-runs daily.
It joins glue-bao-readers-policy-order, so it is ordered after its policy
unit (`after` and `wants`, never `requires`) where the store is on the
same host. The policy unit joins the store's journald list.
- nats gets `tls {}`, with the key via `LoadCredential`, and no
`allow_non_tls`. `validateConfig` is now off in every mode, because the
build-time check loads a leaf that only exists at runtime.
- 4222 is also open on `wg-hive` when the host is on the mesh, never
host-wide.
- `statusPublish.natsUrl`, `queue.agentNatsUrl`, the controller's URL under
`singleHostSwarm`, and the auth responder all dial
`tls://<swarm.nats.domain>:<port>`. swarm-queue-client hands its CA file
to the NATS connection too, so hive-c0re and the controller trust the
leaf's root.
- docs/swarm/README.md: the queue URL and the one DNS record a multi-host
swarm needs.
module-eval-nats-tls pins the role, the policy, the served leaf, the
firewall, the ordering, and a scan of every `*_NATS_URL` and the
responder's URL across the host and its containers.

The scope-parameter addition pushed the doc comment on token_request to 39
lines. Moved the HTTP-Basic incident story and the audience/scope rationale
to the crate README's new "Token request shape" section (docs/ is markdown,
exempt from the lint); the code comment keeps the pointer plus the one-line
summary of the invariant. Refs #4464
`swarm-logs query` got a bare nginx 401 from the swarm log store on every
query. The agent OIDC client is registered for `authelia.bearer.authz`
(`swarm-authelia.nix`'s `agentClients` sets `bearerAuthz`), but registration
is not issuance: the token request asked for no scope, so the token came back
carrying none, and authelia's `/api/authz/auth-request` refuses that exactly
as it refuses an unauthenticated caller.
The same failure is already recorded in `swarm-otel.nix` against the
collector's client, on the same scope string — prometheus asks for no scopes
unless told to, and every scrape was refused at introspection. This is that
bug one layer down, so it gets the same shape of fix.
`scope` becomes an opt-in parameter alongside `audience`, not a hardcoded
value or a config field: the two travel together (registered ≠ requested
applies to both) and only the destination decides whether either is needed.
`None` keeps every other caller byte-identical — the NATS connect callback,
`auth.rs`'s bridge client and the OTLP push client all pass it.
Refs #4464
A publisher of variable-size rows has to size them against the server's
limit before it publishes, because exceeding it is not a truncation: the
server answers `Maximum Payload Violation` and closes the connection, so
the row is lost and the client reconnects.
The limit belongs to the queue's NixOS module, which is the only place
that chooses it. Reading it off the connection rather than restating it
as a constant keeps it spelled once — a client-side copy would be a
second opinion about a number it does not own, and would go stale the
day an operator raised the real one.
No test: the value comes from the server's INFO line, so anything
asserted about it without a running server would only be re-asserting
async-nats's own pre-connect default.
Refs #3805
mara on #4015: "not merging code without callers", and on the same PR
"see issue, we decided what the first thing should be". #3726 decided it:
the controller writes a token to the store and tells the hive; the hive
reads it back and writes /agents/<agent>/state/matrix-token-<account> at
0600, where matrix.nix's existing systemd.paths glob re-fires the daemon.
So this is the hive half of that, and the library's first caller.
The notice names a credential and never carries one, and deploy_subject's
own doc is why: the auth-callout responder scopes publish and leaves sub
unrestricted, so a hive that wanted another's messages could subscribe to
them. A secret in that payload would be readable swarm-wide. The value is
read from the store under the reading hive's own certificate, where the
store's policy is what actually scopes it.
Two boundaries guard the two addresses, and they are not the same check.
`path::matrix_account` guards the address in the store. `Ident` guards the
address on disk -- `agent_state_dir` takes one, so an unvalidated name off
the queue cannot reach a directory. I had written the first and assumed it
covered both; the compiler refused the `&str` and was right. `token_path`
now takes the newtype so a call site cannot forget.
The write is atomic because the path-watcher fires on the file appearing:
written in place it would be visible while partial, and the daemon would
read a truncated credential exactly once, which is the hardest possible
failure to reproduce. The temp name is dot-prefixed so it cannot match the
`matrix-token*` glob on its way past.
The publish grant is here because without it the failure is invisible.
policy.rs already says why for its siblings: a refused publish reaches the
client as a timeout, so the symptom is a hive that never receives a
credential with nothing in either log naming a permission. Two tests: the
controller may publish, a hive may not -- its own subject included. A
forged notice leaks nothing, but it would make a hive fetch and overwrite
a token file for a name the forger chose.

CHECKPOINT, NOT A PROPOSAL. mara paused the plan ("i dont quite understand
the plan") before any behaviour-changing edit; this commit exists so the work
survives a container stop, not because it is ready.
wanted.rs: BUCKET -> BUCKET_PREFIX + bucket(hive) producing hive-wanted-<hive>;
open_or_create/open_read_only take the hive. lib.rs: Error::CreateBucket.bucket
becomes String, since a per-hive name is built at runtime.
Nothing else is touched, so no caller compiles against the new signatures yet
and no deployed behaviour changes. Remaining, if she approves: the two other
CreateBucket sites, swarm-controller's OnceCell (one store -> N), hive-c0re's
pull, policy.rs per-hive streams + the reader roster, swarm-nats.nix.
The controller declares each hive's wanted agent set; the hive reads its own
key. Deliberately not a mirror of `status`, which the module documents as a
table: authored by the controller rather than the hive, DECLARED rather than
observed, and — the row that decides how it must be built — unrecoverable if
the store is lost, where status regenerates because every hive republishes
what it is.
Two open functions rather than one shared `open_or_create`. `status` shares its
constructor because either end may legitimately arrive first on a fresh swarm;
here the writer is single and known, so the hive gets a read-only open
returning `Option` and holds no grant to create the bucket. Its absence is the
ordinary pre-publication state, not an error a hive could fix.
Absence is also not a deletion order, which the module says at the place an
implementer will meet it: swarm-side lifecycle does not yet cover agents that
predate it, so a hive finding no key has learned nothing about what it runs —
converging to an empty set would tear those down.
No consumer yet. This is the half that is invariant under the scope semantics
and cadence still being decided.
