Without a run cgroup (no delegation, setup failed, or one create
failed) a subagent run was started plain at oom_score_adj 0, below the
+500 the unit gave it before. Every run of the daemon now goes through
the entry wrapper; it sets +1000 and enters the cgroup only when there
is one. run_cgroup::entry takes the cgroup as an Option.
hive-subagent-daemon and hive-bash-daemon are now delegated their cgroup
(Delegate=memory pids, DelegateSubgroup=daemon). At start each daemon
enables memory+pids below its unit and creates runs/ (subagent) or
tasks/ (bash). Each subagent run gets runs/<name>-<n>/ and each bash
task tasks/<id>/, both with memory.oom.group=1, and the daemon removes
the directory when the run ends. An OOM kill now takes one whole run
instead of one process out of the daemon's shared cgroup, and never the
daemon itself.
Subagent runs get oom_score_adj +1000; bash tasks and both daemons stay
at 0; the harness stays at -500. The unit-level OOMScoreAdjust=500 on
the subagent daemon goes: it was both the daemon's own score and a floor
no run below it could be lowered past.
Bash tasks enter their cgroup from the existing pre_exec hook, writing
to a cgroup.procs fd opened by the parent. hive-claude builds its
Command itself and exposes neither a pre_exec hook nor the child's pid,
so a subagent's claude (and an ACP agent's process) is started as the
daemon's own binary with the run's cgroup in its environment; main()
enters the cgroup, raises oom_score_adj and execs the real program, the
trampoline swarm-review-classifier already uses. Both enter before the
program executes, so nothing it forks starts outside the run's cgroup.
Without a delegated `daemon` leaf (tests, a dev shell) each daemon logs
one warning and runs everything in its own cgroup, as before.
The shared helper is hive-agent-sock's run_cgroup module, the crate
both daemons already use for what in-container plugins share.
Closes#5007
After a rollback, a record a newer build wrote (a new enum variant, a
changed required field) stopped decoding, and the strict
`schedules::read` turned that into an error on every read and write of
the key until someone deleted it by hand.
- agent_limits / inference (one document per agent): an undecodable
document reads as unset, with a WARN naming the bucket, key and error.
The PUT's "equal to stored, skip the write" shortcut no longer applies
to an undecodable document, so a PUT of the defaults replaces it too.
- schedule definitions (one document, every schedule): salvaged per
definition, as the review-classifier run list is. An undecodable
definition is kept as its raw JSON, hidden from the list, edits and
projections, written back by every commit after the readable ones, and
its id is never minted again. A document with no list of schedules
stays an error: reading it as empty would empty every agent's key.
- per-agent agent-schedules: an undecodable key reads as no schedules
and is rewritten on the next projection, even when the agent has none.
`schedules::read` is replaced by `read_or_default`; `wanted` keeps its
own strict read.
Closes#5193
Seven host oneshots fetch a secret from the swarm secret store into a file
their consumer loads at start: swarm-bao-grafana-oidc, swarm-bao-otel-oidc,
swarm-bao-matrix-oidc, swarm-bao-ci-runner, swarm-bao-forge-oidc,
swarm-bao-hive-otel-oidc and swarm-bao-forwarder-oidc. Each was
RemainAfterExit with no timer, so it ran at boot or deploy and never again:
a secret re-minted in the store reached its consumer only through an
operator restarting the fetch.
lib/store-refresh-timer.nix gives each one a timer (OnUnitInactiveSec 10min,
RandomizedDelaySec 1min, the agent's own store re-read interval), and each
drops RemainAfterExit so a timer start is not a no-op. Each script already
writes the file only when secret_differs, and refresh_consumer/refresh_unit
restart the consumer only when the file is newer than its last start, so a
run reading an unchanged value restarts nothing.
Two docs said these units do not run on a timer; credentials.md's
ci-runner row said the runner token is not re-pulled.
Part of #5017 (slice T).
systemd ignores `08%` and `085480%` for CPUQuota= and `08%` for MemoryMax=
("Invalid ... ignoring"), which leaves the agent uncapped. `hundredths` now
refuses a whole part that starts with `0` unless it is exactly `0`, for both
fields. `0.5%` and `0.01%` stay accepted.
systemd ignores a CPUQuota= or MemoryMax= it can't parse ("Invalid ...,
ignoring") and runs the unit without that limit. A swarm cap replaces
the hive's answer, so such a value left the agent uncapped while the
route, GET and the dashboard all said it was capped. argus on #4268 (R3)
found values the route took that systemd ignores: 12.345%, 400.123%,
0.001%, 17000000T, 99999999999999999999T and 99999999999999999999%.
The validators now accept a subset of what systemd parses, measured
against `systemd-analyze verify` (systemd 260):
- a percentage takes at most two decimals and is above zero, up to 100%
for memory_max and 21474836.47% for cpu_quota (systemd keeps the quota
in hundredths of a percent in a C int, not a u64)
- a size is one parse_size term: digits, an optional fraction, then
nothing, B, K, M, G or T, case-sensitive. The whole part and the
fraction digits fit u64, the whole part (plus one with a fraction)
fits u64 once scaled, and the byte count is at least 1 and below
2^64 - 1, as systemd checks them.
P and E, which systemd reads, stay refused because hive-c0re's validator
refuses them, and one value the hive refuses stops every cap update on
that hive. Values are stored as given: lower-case suffixes and a B
after a multiplier are refused rather than normalized, as systemd
refuses them.
The newline-injection values from the hive's test are in both bad lists
and go through the router in a_cap_with_a_second_line_is_a_400_and_the_caps_stay.
GET reads through a new agent_limits::open that returns None for a
missing bucket, answered as {}, instead of creating the bucket.
Every 30 seconds `workers::swarm_limits` reads the `agent-limits` key of
each agent this hive has and stores the result in
swarm-resource-limits.json, where the drop-in, the heap ceiling and the
dashboard read it. A cap therefore follows its agent to whichever hive
runs it.
Each value goes through the hive's own validate_cpu_quota /
validate_memory_max before it is stored, since hive-priv renders it
verbatim into the container's drop-in, and one bad value refuses the whole
set (argus on #4268, carried over from the wanted-state consumer this
replaces). A failed read, or a bucket that does not answer, leaves the
stored caps as they are; three failures in a row raise a banner.
swarm-nats-auth grants every hive `$JS.API.DIRECT.GET.KV_agent-limits.>`:
read-only, and every agent's key, not just the hive's own. Scoping it to
the hive's agents would need a roster in the auth responder, which
policy.rs argues against. mara chose this on #4268 (c95293); narrowing it
is a possible low-priority follow-up, not planned. A test pins that the
grant reads every key, writes none, and reaches no other bucket.
Contributes to #3865.
The cap file was removed for a cap of `infinity` or a RAM percentage,
so the boot check warned on every start of such an agent, for a
legitimate config. The file is now written on every start:
- a size: its byte count, as before;
- `infinity`: the literal `infinity`. The generators set no JSC heap
ceiling and no subagent MemoryHigh=, and the boot check is quiet;
- a percentage: resolved on the host the way systemd resolves
MemoryMax=N% for the container@ unit. That is permyriad (at most two
decimals, at most 100%) of sysconf(_SC_PHYS_PAGES) *
sysconf(_SC_PAGESIZE), rounded down to a page;
- a value systemd ignores (zero, over 100%, more than two decimals,
unparseable) leaves the unit uncapped, so it is `infinity`.
The file is missing only when hive-c0re can't tell the cap: the
limits file and the kept drop-in are both unreadable, or a percentage
meets an unknown host memory size. The boot check now warns only for
a missing file or a first line that is neither a byte count nor
`infinity`.
Part of #5081 (slice S0-2).
When hive-c0re can't read resource-limits.json and a limits drop-in
already exists, it keeps the drop-in, but it wrote no memory cap file. A
container whose runtime dir had no file yet (hive-c0re upgraded, /run
not cleared) then started with no heap ceiling and no subagent
MemoryHigh=, silently. `stage_limits` now writes the file on every
call: from the new limits, or from the last `MemoryMax=` in the kept
drop-in (`infinity` when it has none or can't be read).
A missing or malformed cap file at boot is no longer silent. The
generators run before the container's journal and an nspawn container
has no /dev/kmsg, so a oneshot `hyperhive-memory-cap-check.service`
logs a warning naming the path. The agent then runs with no JSC heap
ceiling and no subagent MemoryHigh=; the container's MemoryMax= still
applies.
module-eval-agent-memory gains a case pinning how the ceiling reaches
claude: `hive-agent` and `hive-subagent-daemon` neither set nor unset
BUN_JSC_forceRAMSize, both generators and the check unit are installed.
Part of #5081 (slice S0-2).
An agent's memory cap was rendered into its flake (`memoryMaxBytes` →
`services.hyperhive.agent.claudeMemoryMaxBytes`), so the closure depended
on it and a changed cap reached the JSC heap ceiling and the subagent
`MemoryHigh=` only after a rebuild.
hive-c0re now writes the effective `MemoryMax=` in bytes to the agent's
runtime dir (`/run/hive/memory-max-bytes` inside) in `write_dropins`,
from the same value the drop-in gets. The file is removed for
`infinity` or a RAM percentage, and left alone when the drop-in is kept.
Inside the container, `nix/agent-modules/memory-cap.nix` reads it at
boot: an environment generator sets `BUN_JSC_forceRAMSize` (75%) for
every unit and `machinectl shell`, `/etc/set-environment` exports it in
login shells, and a unit generator writes `MemoryHigh=` (2/3) as a
drop-in for `hive-subagent-daemon`.
The render drops `memoryMaxBytes`, the agent option is removed (both
spellings fail eval with a removal message), and
`effective_memory_bytes_from` goes with its only caller.
Part of #5081 (slice S0-2).
Part of #5081 (slice S0-1a). An agent's closure no longer depends on the
name or domain of the hive that renders it.
- hive-priv writes /etc/hyperhive-hive-facts (HYPERHIVE_HIVE_NAME,
HYPERHIVE_HIVE_DOMAIN) into the container from the same WriteNspawnFlags
call that writes /etc/hyperhive-bridge-dns. hive-c0re passes the values
from its own unit env. hive-priv refuses a value outside [A-Za-z0-9._-].
- A systemd environment generator in the agent (hive-facts.nix) loads the
file into the container manager's environment, so every unit sees it,
as with the systemd.globalEnvironment entries the render used to emit.
It also builds CLAUDE_REMOTE_CONTROL_SESSION_NAME_PREFIX
(<hive>-<agent>), which left claude's managed settings.
- meta.rs stops forwarding HYPERHIVE_HIVE_{NAME,DOMAIN} and stops setting
services.hyperhive.agent.hiveName. The option is removed (both
spellings now fail with a removal message).
- otel.nix drops the agent's hive= resource label. The swarm collector
upserts hive per authenticated receiver (swarm-otel.nix resource/<h>,
on both the metrics and logs pipelines), so stored series keep it.
The otel first hop, otel enable and the dashboard port are still baked;
they are S0-1b.
The previous commit dropped `hive-otel-client-secret` and the collector's
`requires`/`after` on it for every hive. Only the store fetch restarts the
collector when its file lands; an operator-named `otel.clientSecretFile`
has nothing doing that, so a late file failed `LoadCredential` straight into
the collector's start limit with no way back.
The wait unit and the ordering are back for `senderAuth && !fetches`, and
absent only where `swarm-bao-hive-otel-oidc` delivers the file. The
module-eval case for a hand-named secret now also pins the wait unit and
the collector's `requires`/`after` on it, on both of its fixtures.
Refs #5015
The hive collector's `oauth2client` secret came from a `clientSecretFile`
defaulting to authelia's own minted file on the IdP's host, with a
`hive-otel-client-secret` oneshot that only waited up to 120s for that
file to exist; any other hive had to copy the file across by hand.
`swarm-bao-hive-otel-oidc` now logs in with the hive's leaf
(`deploy.bao.clientCertFile`), reads `swarm/hives/<hive>/oidc/client`
(written by the publisher, granted by the hive leaf's
`swarm/hives/<hive>/*` read), writes it root 0400 when it differs, and
restarts the collector when the file is newer than its last start.
Retries every 30s for 24h (`lib/store-retry.nix`), like the matrix and
forge fetches. `clientSecretFile` defaults to that file wherever the hive
leaf is set and stays as an override; an overridden file renders no fetch.
otelcol-contrib 0.151.0's oauth2client re-reads `client_secret_file` on
every token fetch, but the path is `LoadCredential`'s start-time copy, so a
changed secret still needs a restart. `lib/refresh-consumer.nix` gains
`refresh_unit` for a host unit; `refresh_consumer` now calls it with
`--machine`.
nats-authelia's "consumer of the host client-secret dir" case pointed at
the collector's old default; it now reads the publisher's path unit.
Refs #5015
With actionsFromSelf, Forgejo resolves bare `uses: actions/<name>` against
the forge itself, so every action a workflow names needs a mirror there.
Only actions/checkout was seeded, and coverage.yml's
`actions/upload-artifact@v3` has failed at job setup with "repository not
found" since the CI runner moved to swarm-ci-runner (e2da5509).
The single hardcoded checkout mirror becomes a list of action names both
share, mirrored from github.com/actions/* like checkout already was. v3
points at the same commit (ff15f03) on github.com and code.forgejo.org.
The controller's forge-objects pass creates any missing mirror on every
pass, and the changed SWARM_CONTROLLER_FORGE_MIRRORS env restarts the unit
on switch, so an existing forge picks the mirror up on deploy.
Closes#5040
swarm.forge.ci.* were per-host options that 4423da48 had already moved to deploy.forgejo.ci.*, so they rename straight to deploy.ci-runner like the forgejo.ci ones; ciRunnerRemoved goes with its last caller.
The forwarded enable now trips deploy.ci-runner's store-identity assertion on a host with no deploy.bao.enable. The assertion names both options and the default, the doc states the requirement, and a module-eval case pins the refusal.
deploy.forgejo.ci.{enable,name,concurrency,labels,package,jobTimeout} each
have a same-typed, same-meaning counterpart under deploy.ci-runner on the
same host, so they are mkRenamedOptionModule entries again and a config that
still sets them evaluates with the standard rename warning. The swarm.forge.ci
spellings stay removals.
docs/scheduler/ci.md states the rename, that the old hive-ci runner's entry
is deleted by hand in the forge admin panel, and that actionsFromSelf
defaults on where the controller runs.
The disk sampler ran `du -sxb` as the unprivileged hive-core user over
each agent's state/, work/ and container rootfs. hive-core cannot read
the rootfs or all of the agent-owned files, so `du` failed and each
failed path silently counted as 0: the dashboard showed a few MB for
agents using over 13 GB.
Add a hive-priv `MeasureAgentDisk { agent_name }` op. hive-priv
validates the name, derives the three paths itself (the request carries
no path), skips the ones that don't exist, and runs one
`du -s -x -b -c -P` as root with a 10 min timeout. A timeout, a non-zero
exit or output without a `total` line is an error.
hive-c0re calls it every 30 min instead of running `du` every 5 min:
each pass walks every agent's full tree as root on the disk the agents
work on, and the sizes move slowly. A failed measurement is cached as
None, so `disk_bytes` is null, the OTel storage.usage sample is omitted
and the dashboard shows "unknown", never 0.
`Coordinator::agent_work_dir` had no other caller and is removed.
Closes#4956
systemd hands a unit's credentials to every process of that unit, and a
host job is a process of the runner daemon, so the `LoadCredential=` on
gitea-runner-swarm still let any workflow read the registration token
from `$CREDENTIALS_DIRECTORY`.
swarm-ci-runner-register.service, a oneshot under the daemon's dynamic
user and state dir, now holds the only `LoadCredential=` and runs the
precond and `act_runner register` (only when `.runner` is missing). The
daemon unit has no credential, no `EnvironmentFile` and no `TOKEN`; its
pre-start step starts the register unit, so a missing token fails the
daemon's start and `Restart=on-failure` retries it.
The precond compares `.runner`'s labels in the form the daemon rewrites
them to (`nix` -> `nix:host`); compared verbatim, a scheme-less label
re-registered the runner on every start.
tmpfiles removes the unused `registration-token.env` and upstream's
`.token-hash`/`.labels` markers.
The runner got its registration token through an `EnvironmentFile`
(`TOKEN=…`), so the daemon carried it for its whole life, and for a
`host` label act_runner copies its environment into every job step:
any workflow could read a token that registers runners on the forge.
The host unit now writes the bare token, and the runner unit loads it
with `LoadCredential=`. The upstream pre-start step, which registered
from `$TOKEN`, is replaced by one register step that reads the token
from `$CREDENTIALS_DIRECTORY` and runs `act_runner register` only when
`.runner` is missing, with the instance URL, name, labels and config
file upstream used. The precond now also removes `.runner` when its
labels differ from the configured ones, which upstream's step covered.
A changed token alone no longer re-registers.
Host jobs can still read `.runner` itself (#4979).
Closes#4974
The controller seeds the actions/checkout mirror from its own host's
mirror list, so a forge host without it got DEFAULT_ACTIONS_URL = self
and no mirror. The default now follows
deploy.swarm-controller.enable; the module-eval check pins forge-only
(false, no warning) and forge+controller (true, mirror seeded).
The CI runner was a hive deploy module: hive-ci.nix ran it beside the
forge, and hive-c0re registered it through the forge's admin API with
the `core` token, writing the registration token through hive-priv. It
could only run on the forge's host, and it kept an admin-scoped forge
token on a hive.
Now the runner is a swarm service:
- swarm-ci-runner.nix runs it in a `swarm-ci-runner` container on the
host that sets deploy.ci-runner.enable, reaching the forge by name.
It needs neither the forge nor a hive there.
- swarm-controller reads the forge's runner registration token with its
own admin token and writes it to swarm/services/ci-runner/
registration-token whenever it differs from what it last wrote. Its
grant on that path is create/update only.
- The runner's own leaf (CN swarm-ci-runner, role and policy of the same
name) reads that one path. swarm-bao-ci-runner.service fetches it into
the runner's EnvironmentFile and restarts the runner on a change.
- A pre-start step removes .runner when the daemon's journal since its
last start holds Forgejo's "unregistered runner" refusal (the daemon
exits 1 when its startup Declare gets it), or when .runner names
another forge address; upstream's pre-start step then registers again.
Removed from the hive side: hive-ci.nix and deploy.forgejo.ci.*,
forge/ci_runner.rs, PrivRequest::RegisterCiRunner and its handler and
ReadWritePaths entry, InfraContainer::Ci with hivectl's --ci and the
dashboard's hive-ci journal entry, HYPERHIVE_FORGE_CI_ENABLED, and
read:admin,write:admin from CORE_TOKEN_SCOPES: nothing else in hive-c0re
calls /api/v1/admin/*. The old ci options, under both swarm.forge.ci and
deploy.forgejo.ci, now fail evaluation naming deploy.ci-runner.
The forge's half of the old ci.enable, the actions/checkout mirror and
DEFAULT_ACTIONS_URL = self, is deploy.forgejo.actionsFromSelf.
Closes#4954
config-changes.md (was approvals.md) describes config PRs, the meta flake

section and the loose-end/cancel kind, and links to the renamed page.

group and the removed endpoints/events, pointing at docs/swarm/schedules.md.
Rewrites the config-change flow around the forge merge and the

The forge always sits behind the gateway, so `deploy.forgejo.behindGateway`
(and its `swarm.forge.behindGateway` rename alias) is removed and its
true-branch behaviour is now unconditional within `deploy.forgejo.enable`:
https ROOT_URL on the gateway's httpsPort, the forge vhost and local DNS
name, the swarm-ui quick link, the published metrics scrape target, forgejo
metrics, the authelia `/metrics` rule, and `publicUrl` defaulting to
`https://<forge.domain>`.
Removed with it: the direct-port `http://<domain>:<httpPort>/` ROOT_URL
branch, the hive-ci assertion that the option is true, the core-toggle
cases that only exercised the false branch (the services-leaf case reads
`bare`, which never enabled the forge either). `hivectl open forge` now
points at `swarm.forge.publicUrl`, which can still be set to null.

observability.md: "Why two tiers" claimed the harness currently writes an
upstream token into the agent's own claude settings; that path was removed
with the direct-export mode it served (nix/agent-modules/otel.nix:56-63).
Reworded as the hypothetical the paragraph is actually making.
gateway.md: restored the agent-trust pointer to
/run/hive-ca/trust-bundle.pem in "Cert prompts" (hive-ca-trust.nix:41),
dropped by the earlier rewrite. Corrected the SPA-fallback section: only
the chat.<swarm> vhost uses the Accept-header map
(hive-matrix.nix:693-696); per-agent split mode uses file-existence
try_files (gateway_nginx.rs:93-134), not the same mechanism.

Per mara's #4879 review (89815): the system has no agent hierarchy,
just a flat set scoped by the capability store, so the filename no
longer matched. The file already read "Agent roster & privileges"
after the earlier facts pass; rename it to match, and update the
four inbound references (docs/README.md, coordinator.md, config.md,
agent-service.nix).
An ACP agent's `usage_update` carries `cost.{amount,currency}`, the
session's running total (opencode sums every assistant message in the
session). hive-runtime now reads it and turns the running total into
what each report added: a new session counts from zero, a session loaded
into a freshly started agent only baselines on its first report, and a
falling total adds nothing. The spend is held on the runtime until
`Runtime::take_reported_cost` drains it; claude's runtime reports none,
since the claude binary already exports `claude_code.cost.usage`.
hive-agent's existing turn-metrics meter records three new instruments:
- `hyperhive.agent.cost.usage` (counter, `model` + `currency`), ACP only;
- `hyperhive.agent.context.used` / `.size` (gauges, no attributes), for
every backend: the two numbers the web UI's ctx% divides.
The `hyperhive · agents` dashboard gets ACP cost panels on its cost tab
and a context-fill panel on its health tab.

addresses argus's review on #4842 (c88740): fetch's success path was
silent when the response parsed but windows() found nothing to record.
should_warn_empty tracks the same once-per-streak shape as the
existing token-skip logging, reset the moment a response has windows
again, and never logs the body.
Also notes in the observability doc that a past resets_at means the
paired percent gauge is stale.
A detached task polls GET https://api.anthropic.com/api/oauth/usage every
5 minutes with the OAuth access token from ~/.claude/.credentials.json and
records, per window the response names (five_hour, seven_day,
seven_day_sonnet, ...):
- hyperhive.agent.claude_usage.percent (%, 0-100)
- hyperhive.agent.claude_usage.resets_at (s, unix seconds)
both labelled window=<name>. Endpoint, the anthropic-beta:
oauth-2025-04-20 header and the {utilization, resets_at} window shape are
taken from the claude-code 2.1.283 bundle's own /usage fetch.
The token is only read, never refreshed: claude owns refresh-token
rotation and a second refresher can log the agent out. An expired token
is skipped until claude's next turn refreshes it. API-key agents
(HIVE_USE_API_KEY, the ACP default) and agents with no credentials file
skip quietly, and the task does nothing when OTEL is not configured.
Request failures and non-2xx statuses warn with the status or transport
error only, never the body or the token.
swarm-controller's POST /api/agents now refuses (409) a name the swarm
has already placed on a different hive: a non-Destroyed declaration in
that hive's wanted state, or a SetAgentWanted node still queued for it.
The same name on the same hive is that agent being re-created and goes
through. A wanted state that cannot be read refuses (503/500) instead of
reading as "placed nowhere". Creations are serialised from that read to
the graph insert so two concurrent creations of one name cannot both
pass.
Hive-level creation is removed: hivectl `agent create` / `request-create`,
HostRequest::Spawn / RequestSpawn, the dashboard POST /api/request-spawn
route, and ApprovalKind::Spawn with its approve/resolve arms and the
approval-carrying `templates::spawn`. The swarm path (deploy request or
wanted-state sweep -> queue_first_deploy -> templates::first_deploy) used
none of them. Old `spawn` approval rows are skipped by collect_lenient,
as `init_config` rows were in a3b672d1.
policy.rs's comment on agent_object_name stated swarm-wide name
uniqueness as a fact; it now says where it is enforced and what that
check cannot see.

mara chose to accept extra queued sweep passes over adding a new
hive-jobq primitive (or a hive-c0re one-off) for "don't queue another
of this kind". Every sweep caller now plain-inserts its node; the
capacity-1 Dep::Resource per sweep kind (MatrixSweep/KnowledgeTree)
still keeps two passes of the same kind from running concurrently, it
just no longer collapses a tick that lands while one is live or queued
into the existing one.
The matrix sweep and the /knowledge pull each had concurrent callers
(#4723 item 4). Two overlapping knowledge pulls fail on .git/index.lock
and the remote-tracking ref lock: 30 of 30 concurrent replays of the
reset/clean/pull sequence in a scratch repo errored, 0 of 10 sequential
ones did. Two overlapping matrix sweeps on a hive with no persisted
Space / chat-room id both miss the by-name lookup and both createRoom
(from reading the code, not reproduced against a homeserver). On every
boot the MatrixSweep DAG node and the main.rs loop's immediate first
call ran at once.
Every sweep now runs as a job node, and each sweep's node holds its own
capacity-1 queue resource (Resource::MatrixSweep,
Resource::KnowledgeTree), the MetaWindow pattern: the scheduler never
starts a second pass of one sweep while the first holds the resource,
and different sweeps still run side by side.
- templates::matrix_sweep / templates::knowledge_pull build the node
with its resource; boot, the periodic loops and the swarm event all
use them.
- JobQueue::insert_unless_live folds a submission into a live node of
the same kind instead of queueing another. Periodic ticks fold into a
queued or running pass. The swarm knowledge event folds into a queued
pull only, and queues one behind a running pull, which may have
fetched before the push.
- The main.rs matrix loop no longer sweeps immediately at startup; the
boot MatrixSweep node is the startup pass, as KnowledgePull already
was for knowledge.
- The executors bound each pass (10 min matrix, 5 min knowledge), since
a hung pass would otherwise hold its resource against every later one,
and own the sweep-health banners, so every pass reports to them.
Replaces the SweepLock version of this branch, per review.

/etc/tmpfiles.d/hyperhive-agents.conf was a boot-time backstop (#2290)
that pre-created every agent's bind sources. The start preamble already
creates them for every c0re-driven start, and on this host only hive-c0re
starts agent containers. The file was also the reason the socket dir's
owner had to be declared there, which is how it spent its life at
`0777 root root` whenever the uid could not be resolved (#4742).
- hive-priv gains `EnsureAgentSocketDir { name }`, called from
`set_nspawn_flags` in every start path. It creates
`/run/hive-agent/<name>` `0751 root:root` with mkdirat relative to an
O_DIRECTORY|O_NOFOLLOW fd for the parent. An existing entry has to be a
directory (fstatat AT_SYMLINK_NOFOLLOW); anything else is refused, and a
directory is left alone. hive-c0re's own create_dir_all went: its /run
is read-only under ProtectSystem=strict.
- The container's `hive-agent-user-migrate` activation chowns that dir to
the agent user and sets 0751, the same way it already handles state/ and
harness/. It refuses a symlink or non-directory there, since `test -d`
and chmod follow links. No host-side passwd parse, and no window where
the dir is world-writable.
- `/run/hyperhive/agents/<name>` stays created by hive-c0re itself
(`ensure_agent_runtime_dir`). It holds the `mcp.sock` that hive-c0re
binds as hive-core, so it must not become root- or agent-owned.
- The `/run/hive-agent` parent is declared in hive-priv.nix, `0755
root:root`, instead of hive-gateway's hive-core rule. hive-priv is its
only writer now, and hive-priv's ReadWritePaths needs it to exist.
- The manager start in `ensure_root_agent` now goes through
`converge_start_preamble` + `start_with_fallback`. It was a bare start,
so after a reboot the manager's bind sources existed only because of the
tmpfiles file, and its limits drop-in did not exist at all.
- Removed: `sync_tmpfiles`, `agent_uid_gid` / `parse_passwd_uid_gid`,
`priv_client::sync_agent_tmpfiles`, `AgentTmpfilesEntry`, the tmpfiles
body builder and their tests, plus the three call sites.
- Legacy: hive-priv unlinks the file at every start, ignoring ENOENT.
`SyncAgentTmpfiles` stays one release as a payload-ignoring variant that
does the same unlink and returns Ok, for an older hive-c0re.
Salvaged from #4752: the boundary.md correction that nginx only dials,
because ProtectSystem=strict makes its /run read-only.
Behaviour change: a manual `nixos-container start h-<name>` right after a
reboot, before hive-c0re has started that agent, now fails on a missing
bind source instead of starting.
Closes#4742
The orgs agent-configs/internal/agents (plus mirror owners), the
operators team in agents and agent-configs, the pull-mirrors,
internal/docs, internal/knowledge (public, README-seeded) and the
agent-configs org avatar are one set per forge. hive-c0re ensured them in
its boot sweep, as the core admin, and only on the hive co-located with
the forge container.
swarm-controller now reconciles them at start and every 5 minutes
(forge/objects.rs: observe -> pure plan -> apply). A failed object logs
a warn line plus a pass summary and is retried next tick. create_repo
ensures the agent-configs org and its operators team first, so a config
repo's merge gate never depends on the periodic pass having run.
hive-c0re drops ensure_org, SEEDED_ORGS, ensure_mirrors/ensure_mirror_repo,
ensure_operators_team, ensure_shared_docs_repo, ensure_knowledge_repo/
set_repo_public, seed_readme, ensure_config_org_avatar and the one-shot
knowledge::remove_webhook cleanup, with their now-unused helpers.
nix: the mirror list moves from the hive-c0re unit
(HYPERHIVE_FORGE_MIRRORS) to the swarm-controller unit
(SWARM_CONTROLLER_FORGE_MIRRORS), with an eval warning when mirrors are
declared on a host that runs no controller. c0re.orgAvatarPng is renamed
to deploy.swarm-controller.configOrgAvatarPng.

Every hive with hyperhive enabled ran its own hive-forge container, and
its gateway answered forge.<swarm> with its own bridge IP, so on a
multi-host swarm each hive talked to its own forge.
deploy.forgejo.enable defaults to false and allSwarmServices sets it with
mkDefault, like authelia and bao; singleHostSwarm gets it through that.
The forge's OIDC client moves to a glue module gated on authelia, so a
split authelia/forge swarm still registers it. CI now requires the forge
on the same host, and the controller's forgeTokenFile defaults to null
where the forge is not.
Closes#4705

The topology doc keeps its filename and its second half (manager
special-casing, harness unit shape) — both are cross-referenced from
other pages and neither is about the parent field. Its first half is
rewritten: what topology.json is now, and a table of what the removal
took with it, so a reader who finds `<parent>` or `set-parent` in an old
issue thread learns it went away rather than moved.
The dashboard's tree-rendering section is marked dormant rather than
deleted: the walk is still in swarm.js and retiring it is the frontend
owner's call.
2 real active-voice rewrites (per mara: main picked these up via a
rebase+merge that landed after write-good.Passive went error-gate,
never checked against the current rule):
- "The datasource is told instead" -> nix/host-modules/swarm-grafana.nix
tells the datasource instead.
- "`value` is compared with `===`" -> the builder compares `value`
with `===`.
No suppressions, no content dropped.
