`token_path`'s doc claimed the compiler was the check and that nothing had to
remember to perform one. True of `agent`, which is an `Ident`. Not true of
`account`, a bare `&str` concatenated into the filename — safe only because
`deliver` happened to validate it first, which is the caller-must-remember
pattern the comment denied.
Observably a no-op today: the one call site already rejects a bad account
before reaching here. What changes is that the signature now enforces what the
comment asserted, so a second caller cannot skip it.
The check is `path::checked_segment`, made public rather than reimplemented.
Two copies of a charset are two charsets: they agree until one is edited, and
the day they diverge a name is legal in the store and not on disk.
An account name cannot simply become an `Ident` the way an agent name is:
it is an attribute name in `hyperhive.matrixAccounts`, so uppercase and
underscore are already configurable, and narrowing that is a decision rather
than a refactor. The new test's controls pin both.
Found by argus reviewing the merged PR.
The wanted-state read was a boot-time DAG node, so a swarm-level change sat
unapplied until the next restart. This watches the hive's own bucket and
converges on each update.
It does not replace the boot read: a watch hears only what is published while
it is listening, so a hive that was down still learns the current declaration
from `pull`. The watch is the fast path, `pull` stays the repair path.
Rides the connection swarm-status already opens, as a third consumer — a
second connect would double the auth-callout traffic and give the two paths
independent reconnect state, which is the reason the deploy-event drain is
spawned there too.
A delete is not a deletion order. `carries_a_declaration` is pure and tested
so that rule is enforced rather than asserted: converging on a withdrawn key
would tear down exactly the agents "absence is not a deletion order" protects.
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.
Refs #3726
Both were prose about the model this branch replaces, caught in review.
`swarm-controller/src/wanted.rs` was the worse of the two: its header
called the lifecycle "deliberately identical" to `status` and the handle
"resolved on first use and cached", while `store`'s own doc seventy lines
below says "resolved per call rather than cached". One file, two
contradictory claims, and the `OnceCell` that would have settled it is
gone. Rewritten to say where the mirror stops rather than to patch the
stale clause, since the divergence is the point of the change.
`hive-c0re/src/workers/wanted.rs` named a `hive-wanted` bucket that no
longer exists.
Swept by content rather than fixing only the two that were named: the
sweep surfaced a third candidate, `swarm-nats-auth/src/policy.rs`'s
"one key per hive", and reading it cleared it — that sentence is about
the hive-status bucket, whose shape is unchanged. Left alone
deliberately.
A hive reads its own declaration today and that scopes cleanly: DIRECT.GET
carries the key in the subject, so the grant can name it. A *watch* cannot be
scoped that way — a consumer's filter travels in the request payload, so
$JS.API.CONSUMER.CREATE.<stream> grants the whole stream. With every hive in
one bucket, letting a hive watch its own declaration would let it read every
other hive's.
One bucket per hive (hive-wanted-<hive>) makes the stream a hive may hold
exactly as wide as what it is allowed to see, which is what #4006's live-watch
needs. That watch is a separate change; this only moves the boundary.
mara's calls, both on #4006: one stream per hive rather than teaching the auth
responder a hive roster, and a wildcard for the controller — "its okay if
swarm controller can theoretically override hive". A bucket name is a single
subject token with no prefix matching, so no wildcard narrower than * covers N
per-hive buckets; the controller's grant is account-wide by consequence, and
documented as chosen rather than left to look accidental.
The reader arm of #4005's key-layout guard asserted the opposite of that
ruling, so it is replaced rather than deleted: the hive arm survives as
no_hive_may_write_another_role_s_agent_status (with a positive control), and
the_readers_grant_is_deliberately_account_wide pins the decision and names the
ruling, so the width reads as chosen to whoever finds it next.
Two pre-existing negative assertions were silently defanged by the rename --
they matched hive-wanted.beta and $KV.hive-wanted.alpha, strings nothing
produces any more, and kept passing. Both now match current names.
swarm-controller resolves the store per hive per call instead of caching one in
a OnceCell: there is no single handle that serves N buckets, and declarations
change on operator action rather than per tick.
Making `AgentState` `Copy` in the preceding commit is a change to every
consumer of the type, not to the crate that declares it. `hive-c0re` grew its
own consumer while this branch was in review, and under `-D pedantic` a
one-byte enum taken by reference is `trivially_copy_pass_by_ref` and a
`.clone()` on it is `clone_on_copy`. Neither crate is wrong alone; the merge
is.
`decide` now takes the state by value and the call sites drop the `&`. No
behaviour change — the function only matches on the value.
Per mara's go-ahead on hyperhive#3902 ("getting started is good, but
terminal rendering does not go in there i think"):
Moved 21 top-level docs/*.md files into 7 new topic subdirectories
(existing web-ui/, turn-loop/, swarm/, tools/, crates/ untouched):
getting-started/ setup.md
agent-lifecycle/ agent-hierarchy.md, approvals.md, persistence.md
trust-boundary/ boundary.md, security.md
integrations/ forge.md, matrix.md, github.md, knowledge.md
networking/ gateway.md, network.md, snapshot-store.md
scheduler/ jobq.md, coordinator.md, ci.md, observability.md
process/ conventions.md, gotchas.md, pr-review-gate.md
web-ui/ terminal-rendering.md (moved into the EXISTING dir,
per mara's correction to the original getting-started
guess -- it's UI implementation detail, not onboarding)
The physical layout now matches docs/README.md's own topical headers,
which already amounted to this taxonomy -- see the scoping comment on
the issue for the two findings that motivated this (a genuine
duplication between CLAUDE.md's old "Reading paths" list and
docs/README.md's grouped one, since drifted out of sync with each
other; and the flat layout not matching the grouping we already had).
Fixed every cross-reference this moved across the whole repo (~120
files: docs/ internal links at every depth, Rust doc comments, nix
module option docs, crate READMEs) -- verified two ways: a grep sweep
confirming zero remaining references to any old path, and a script
that resolves every markdown link in docs/**/*.md + CLAUDE.md +
README.md against the filesystem and reports anything that doesn't
exist (zero broken links).
Collapsed CLAUDE.md's "Reading paths" section (the duplicate) down to
a pointer at docs/README.md, now the single index. Rewrote
docs/README.md itself to use the new subdirectory paths and added the
one doc it was missing that CLAUDE.md's old copy had (pr-review-gate.md).
Classified all 22 docs/*.md files first via a haiku subagent (mara's
suggestion) on two axes -- proposed grouping and operator-vs-
implementation focus -- before finalizing the taxonomy; spot-checked
the report and found internal inconsistencies (its classification
table disagreed with its own summary section for a few files), so this
taxonomy is my original proposal + the one correction mara gave
directly, not a blind application of the subagent's table. The
operator-focus data it gathered is still useful for a follow-up
content pass (docs skewing 'mixed' rather than pure operator-facing),
not addressed in this PR -- structure only.
nix fmt clean, both pre-push lints clean.
The boot sweep's error arm substituted `Wanted::from_running(running)`,
which is the one value for which `reconcile_action` returns `Noop` — both
ways. An agent whose `agent_power` row could not be read therefore could
never enter `drifted`, so on a fresh rev marker a corrupt row produced one
`warn!` per boot and no other signal, indefinitely.
Classify the unreadable case as its own outcome instead: the agent gets a
boot `Reconcile`, whose `get_or_seed` fails as a per-agent node — a surface
the dashboard already renders — and the failure stops at that one agent.
The classification moved into `boot_action`, a pure function, because the
loop had no tests at all. The first of the five asserts the unreadable case
across every (fresh × running) combination, which is exactly the matrix the
fabricated value made unreachable.
mara's call on the PR: "dont make the enum open, we will just add
entries later". The catch-all variant is gone, and with it the per-agent
inert path.
What changes is where version skew lands, not whether it is handled. An
unrecognised value used to be one agent this hive left alone; it is now a
decode failure for the whole declaration, so a hive running older code
converges *nothing* rather than obeying the agents it happened to
understand. That fails closed instead of dangerous, and it is the right
trade when both ends ship together — which is what "add entries later"
assumes.
The test moved with the property rather than being rewritten in place:
`an_unknown_state_fails_the_whole_declaration` lives in
swarm-queue-client, where the decode is, with a valid entry beside it as
the control. `hive-c0re` keeps a coverage check that every state this
build knows produces an action somewhere — asserting inertness there
would be asserting something the type system no longer lets me build.
The deploy event is a nudge with no second path: core NATS is
at-most-once, so a hive that was down when the controller published
simply never learns that an agent is meant to exist here. This adds the
repair path — one boot-time DAG node that reads this hive's own key in
the `hive-wanted` bucket and converges the agents it names.
Two semantics settled on the issue thread, and both are places where a
plausible implementation is the wrong one:
- **Absence is not a deletion order.** No bucket, no key, or an agent
the value does not name all mean the controller has said nothing.
Swarm-side lifecycle does not yet cover agents that predate it, so
"converge to exactly this set" would tear down every agent the swarm
has not adopted. `plan` only ever inspects the agents a declaration
names.
- **An unrecognised state is inert.** `AgentState` is an open enum: a
value this build cannot read deserialises into `Unrecognised` and is
left alone. A closed enum would force "not `Up`" onto a state like
`paused`, so a controller that learned a new value would take agents
down on every hive not yet updated.
Divergence is measured against the hive's **stored power intent**, not
the container's observed running state — an agent that is down while its
intent says `Up` is already the boot reconcile's work, and a loop reading
`is_running` would insert a start DAG behind that reconcile's back on
every boot. A hive that already agrees with its declaration queues
nothing at all.
`queue_first_deploy` is extracted from the deploy-event path rather than
open-coded here, for the power-intent seed: without it `first_deploy`'s
tail `Reconcile` seeds `Wanted` from a container that exists but has not
started yet, which locks the agent to `Offline` on its first reconcile.
The read is authorised as-is: `store.get` takes async-nats' direct-get
arm (the KV bucket is created with `allow_direct`), which is exactly the
`$JS.API.DIRECT.GET.KV_hive-wanted.$KV.hive-wanted.<hive>` subject
`swarm-nats-auth` grants a hive. The fallback subject is not granted, and
a refused NATS request surfaces as a timeout rather than an error.
Nothing writes the bucket yet — the controller-side writer is the other
half of #3124, so this does not close it.
A webhook has exactly one target URL, so every hive registering one
against the shared internal/knowledge repository was last-writer-wins
rather than idempotent: all but the most recent silently stopped
receiving deliveries. The swarm controller holds the single registration
and now addresses an event to each hive over the queue instead.
This is a migration, not a deletion. Not registering any more fixes
nothing on a hive that has already run — the hook it created persists on
the forge, so the contention would survive on exactly the deployments
that have it while fresh installs looked fixed. The hive that created a
hook removes it.
It removes only its OWN, matched on the full URL rather than the
/webhook/knowledge suffix. A hook with that suffix and a different base
belongs to another hive, possibly one not yet upgraded, and deleting it
would break that hive's knowledge sync until it caught up. Reaping a
neighbour's registration is the behaviour being removed here; doing it
while fixing it would only invert the direction.
The predecessor did reap by suffix, to clear loopback hooks left by an
older single-hive layout. That was safe when a hive was alone on its
forge and is not safe now. The hive-side registrars also acted as reapers
of hooks under their own path, which is why the swarm hook lives under
/webhook/forge/; removing this registrar removes that reaper too.
Intended, and stated because no reviewer would infer it from the diff.
The receive endpoint goes with it. A live HMAC-verified
/webhook/knowledge that nothing can legitimately reach would tell the
next reader that this is how a hive learns about knowledge changes.
Docs move in the same commit: docs/swarm/README.md said two hooks exist
per swarm-wide repo and neither should be deleted, which is now true for
agent-configs and wrong for internal/knowledge — a half-correct
description being worse than an uncorrected one.
A bare `git pull --ff-only` merges whatever `branch.<current>.merge`
lists. A clone carrying more than one such entry aborts with "Cannot
fast-forward to multiple branches", which takes /knowledge out for every
agent on the hive - and the daemon neither writes that config nor can
see it, so the call worked only for as long as it happened to stay
clean.
Reproduced against two throwaway bare repos: duplicate merge entries
give that exact fatal, exit 128. A detached HEAD gives a different
error, and a missing tracking config does not reproduce at all - the
clone of an empty repo does write the tracking entry, so my first
explanation was wrong.
Naming origin and main makes the pull independent of local branch
config: a stray entry degrades to "the pull did not pick it up" instead
of breaking the shared mount. Does not explain how a second entry
appeared; nothing in this tree writes branch config.
Takes the crate from 26 rustdoc warnings to 1, on top of the ten in the
previous commit.
argus's review findings:
- agent_sockets.rs: [`write`] was still ambiguous (function vs macro).
The previous change narrowed the qualifier and left the ambiguity;
[`write()`] is what resolves it.
- forge/users.rs <hex> and stats/container_stats.rs <name>: unclosed
HTML tags in prose, now backticked.
The rest of the crate, so the count actually reaches zero:
- job_queue/mod.rs: Queue::graph_snapshot -> JobQueue::graph_snapshot
(there is no Queue type), and super::scheduler -> scheduler (mod.rs
*is* job_queue, so super:: pointed outside it)
- job_queue/resource.rs: NodeKind -> super::model::NodeKind
- matrix.rs: password_path(name) -> password_path; and
forge::provision_user_token -> crate::forge::provision_user_token.
Note the path has no `users` segment: forge/mod.rs declares `mod
users` private and re-exports it, so the canonical path comes from the
re-export rather than the directory tree.
- socket_server/lifecycle_handlers.rs: InfraContainer ->
hive_priv_sock::InfraContainer
- stats/otel_metrics.rs: crate::meta::otel_config is a private fn no
path can name from another module, so it becomes prose
- main.rs: redundant explicit link target dropped
coordinator.rs:405 (CrashWatchGuard) is deliberately untouched: #3244
deletes that doc block, so fixing it here would conflict with an open PR
and repair a symbol that is about to stop existing.
Remove or fix broken documentation links that accumulate silently:
- container_view.rs: HiveEnv reference
- forge/mod.rs: READY_TIMEOUT and webhook handler links
- workers/knowledge.rs: webhook handler link
- job_queue/model.rs: Claim::deps and WireNode::data references
- stats/hive_stats.rs: read_skill_breakdown reference
- stores/audit_log.rs: global() reference
- workers/agent_sockets.rs: ambiguous agent_sockets::write reference
- coordinator.rs: systemd.services.<harness> formatting
- resource_limits.rs: ambiguous write/read references
Some broken links were to deleted functions/types; these are replaced
with prose descriptions. Others referenced items outside this crate or
were private; these are replaced with plain text references or qualified
paths as appropriate.
Fixes: #3245
Destroy was a straight-line async fn with no queue node behind it, so
nothing in the graph could answer "is this container going down on
purpose?". That gap is why an imperative crash-watch suppression guard
existed: an RAII handle held for the operation's duration, a second way
to say what every other lifecycle op already says through its node.
Reuse the existing Stop node rather than teaching a new node to stop
things:
Stop -> DestroyContainer -> (PurgeState) -> DestroyBookkeeping
Stop already declares takes_container_down honestly, so the suppression
is now derived from the graph like every other op's. It also turns the
precondition into an edge: DestroyContainer runs only under a completed
Stop, so it operates on an already-stopped container and carries
takes_container_down = false permanently. A container still alive at
that point is a real bug and stays loud instead of being absorbed by a
flag -- which matters because a wrong true silently swallows a crash
while a wrong false only costs a spurious event.
Removes suppress_crash_watch, CrashWatchSuppression, crash_suppressed,
crash_watch_suppressed and NO_NODE_LABEL. The migration call sites went
with the obsolete startup migrations, so destroy was the last caller and
intent now has exactly one home.
destroy() becomes a submit-and-return, matching every sibling endpoint
(rebuild, kill, restart, start, pause, resume) -- it was the only
lifecycle op that awaited its work. The container rescan moves into the
bookkeeping tail, so ContainerRemoved now arrives after the 200 rather
than before it.
Also drops an orphaned doc-comment in coordinator.rs: two stacked blocks
where only the second described crash_suppressed, the first documenting
a field that no longer exists. Removing the field would have re-pointed
it at recent_transient.
Per review: docs represent current state. Every "used to" / "no longer"
clause this branch introduced is gone — including the History section in
network.md, which was a whole subsection about a sync mechanism that
doesn't exist.
Where the removed clause was carrying a real constraint, the constraint
stays and is stated in the present tense instead of as a delta: nothing
narrows what the gateway's nginx can reach except the directory
permissions in front of a socket, and nothing bounds `ReloadGatewayNginx`
except the hard-coded unit name. Those read as rules now rather than as
the story of how they came to be rules.
The gateway's nginx + dnsmasq no longer run in their own nspawn container.
`nix/host-modules/hive-gateway/default.nix` loses the
`containers.hive-gateway` wrapper and everything that existed only to punch
holes in it: `privateNetwork = false`, `CAP_NET_ADMIN`, five bind mounts,
its own `stateVersion`, `networking.firewall.enable = false`,
`networking.resolvconf.enable = false`, and the `hive-gateway-resolv`
path+service pair. 465 -> 303 lines.
The container never bought isolation here. It shared the host netns by
necessity — nginx binds the host's :80/:443, dnsmasq answers on the bridge —
so each of those settings was undoing a boundary the gateway could not
afford in the first place.
Four things made it more than a deletion, none of them visible in the nix
diff:
- The self-signed cert service also imports the hive CA leaf, so removing it
with the container would have left nginx naming a missing cert file, which
it refuses to load at all.
- The nginx reload is a hive-priv verb. It still needs root, but no longer
for the reason its doc gave, and `--machine=` was both transport and
scope — so the unit name is now hard-coded in the helper as the
containment.
- The lifecycle verb named a container that stops existing.
- `journalctl -M hive-gateway` had no machine to enter.
Per the operator's ruling, the operator verb keeps working and agents lose
it. `InfraContainer` answered three questions that used to share an answer;
it now splits into `name()` (identity), `target()` (Container vs HostUnit),
`service_unit()` (the systemd unit), and `agent_restartable()`, which the
MCP restart path checks before the capability so the refusal cannot read as
"ask for infra_admin". `SIBLING_CONTAINERS` drops the gateway — it gates the
requests that name a container as a string — while `FromStr` still accepts
it, because that answers what a name is, not who may act on it. The
dashboard's gateway journal reads host journald filtered to `nginx.service`.
Prose was corrected where it only named a location, and re-argued where the
container was doing security work: a `0666` per-agent socket was safe
because only the gateway container had the directory bind-mounted. There is
no mount now, so the directory permissions are the whole of the access
control — the constraint holds, its mechanism doesn't.
Gate: nix fmt / clippy --all-targets -D warnings / cargo test all clean (710
tests); hivectl-cli.md regenerated from the clap tree. The nix eval was run
in both TLS shapes at this commit: every delta in the rendered
virtualHosts is one of the three intended path moves, dnsmasq settings are
byte-identical, and the absence probe flips true -> false with bindMounts
emptied.
Closes the #3110 split — lib.rs is now just the crate doc comment and
the pub mod list.
journal.rs's new doc comment fixes a pre-existing bug: the old
JournalPriority doc text in lib.rs was actually half Capability's doc
(a leftover from an earlier reorder that moved the code but not the
comment above it).
TREE IS RED ON PURPOSE — there is no compiling intermediate between
deleting submit and converting every caller. Checkpoint commit so the
work is durable; do not "fix" it by restoring submit.
Done:
- JobQueue::submit -> JobQueue::insert (no source/reason/container;
returns the ids insert_job names).
- submit.rs deleted. Its 6 pure chain builders + 3 async *_many
gatherers were NOT wrapper code and are rescued into
job_queue/power.rs (templates.rs documents power ops as living
outside it, because their shape needs a live is_running read).
- Converted: meta_inputs 1, topology 2, permissions 3, auto_update 2,
actions 3, lifecycle_handlers 3.
- Dropped source/reason at every converted site: nothing ever read
NodeKind::Dag's fields (only `{ .. }` matches exist), so they are
write-only. Dead reason-only locals deleted; the boot sweep's summary
became a tracing::info! rather than being lost.
Remaining: dashboard/lifecycle_ops 7, server.rs 7, and the test suite —
tests.rs has its own submit() helper whose u64 return is used as the
handle to navigate the inserted DAG, so those need a different way to
find nodes, not a mechanical port.
Deletes `TransientState`, adds `transient_kind` to `TransientCleared`, and
fixes a crash misreport — three changes over the same functions.
`TransientState` was `RunningTransient` with `agent` dropped and
`takes_container_down` renamed; that rename was the only thing it did, and
its three consumers each read a disjoint subset. `transient_snapshot` now
returns `RunningTransient` directly.
`recent_transient` was keyed by agent alone and overwritten on each clear.
An agent can clear several pills in one grace window, so a `Prebuild`
(`takes_container_down = false`) landing after a `StopForUpdate` (`true`)
left the tombstone reading `false` and the crash watcher reported a
deliberate stop as a container crash. Keyed by `(agent, label)` now, with
`recent_transient_within` folding back per agent by OR — the same question
`crash_watch` asks of the active set.
`TransientCleared` gains the label for the same reason: a client holding
two open pills for one agent could not tell which one a clear referred to.
The out-of-band suppression guard has no node and so no label; it uses
`NO_NODE_LABEL`, angle-bracketed to stay out of the `NodeKind::as_str`
namespace.
Renaming `pub type Job` fixed the definition and left every use site
reading `b` and `job` — including `job: super::JobBuilder`, where the
parameter still asserted it was a job while its type said otherwise.
The propagation is what the issue was about, so the parameters are the
half that matters at a call site.
Two spots deliberately untouched: `auto_update`'s `sort_by(|a, b| …)`
comparator, and the prose that means the job *queue* (main.rs's
"Job-queue scheduler", scheduler.rs's "not this module's job any more",
the "grown job rejected" log).
315 tests pass unchanged.
A JobBuilder holds pending nodes that are not in the graph yet — it is
the thing you declare into. Naming the alias Job claimed it was the work
itself, and the name propagated into every parameter derived from it
(job: super::Job in run_node read as if it carried the DAG).
Prose uses meaning the job *queue* are left alone: main.rs's "Job-queue
scheduler" comment and the docs/coordinator.md reference.
315 tests pass unchanged.
Per mara on #2822: status is the only test. The agent comes off the
node's own payload rather than a declared Resource::Agent edge, so the
lease-exempt kinds (Prebuild, MetaSync) that name an agent without
holding its lease now light a pill — they are work on that agent.
Dropping that test breaks the one-pill-per-agent invariant, since
lease-exemption is exactly what lets one DAG build for an agent while
another holds its lease. Everything keyed by agent alone had to follow:
- reconcile_transients keys (agent, label) via TransientSeen, so a
second pill cannot evict the first — and cannot lose its
takes_container_down, which the crash watcher reads at clear time.
- transient_snapshot returns a Vec per agent for the same reason. The
collapse was silent: a Prebuild could evict a StopForUpdate and its
deliberate_stop, making an intentional stop report as a crash.
- crash_watch asks whether ANY running node expects the container down.
- the dashboard renders one row per node instead of one per agent.
takes_container_down never reached the frontend; no wire change needed.
315 tests pass unchanged.
DagSpec described the graph the templates were about to build, one layer
below the templates themselves. Per #2972 the templates should be that
unit, so the spec type is gone and every declarer writes onto the job
builder directly.
- delete DagSpec<F> and its hand-written Debug impl
- submit(source, reason, declare: impl FnOnce(&Job)) replaces the
pre-built-spec signature; submit_and_emit follows
- all six templates take &Job; the Source is now the caller's to pass,
which spawn and approval_deploy previously hardcoded while the other
four did not
- power_dag dissolves into stop_nodes/start_nodes/restart_nodes, which
borrow their targets instead of owning them
315 tests pass unchanged.
A node no longer hands back a recipe for the scheduler to replay later. It
declares straight onto a builder it was given, and that builder is inserted
as part of completing the node.
Deleted: `pub type Declare`, `struct NodeOutput` (+ its hand-written `Debug`),
`JobQueue::append_subgraph`. Nothing added to `Dag` / `DagView`.
jobq gains `Scheduler::new_job()` (the only way to obtain a `JobBuilder`) and
`complete_growing(id, outcome, grown)`, which inserts under `id` and *then*
completes it, so a DAG cannot roll terminal while grown work is still pending.
`complete()` and `complete_growing()` share a private `finish()` rather than
one redirecting through the other. The DAG-gone guard lives beside the graph
now, where it cannot be skipped, instead of being a caller-side lookup.
The growth executors return data (`run_meta_lock -> (Vec<String>, RebuildOpts)`,
`run_reconcile -> Option<NodeKind>`) rather than taking the builder: a `&Job`
parameter is live for the whole function body, and `&RefCell<T>` is never
`Send`, so an async fn taking one cannot be spawned. `run_node` threads the
builder by value and hands it back.
A node can now declare work and then fail, which was previously inexpressible.
`grown` is dropped in that case — failure cancel-cascades downstream, so
inserting it would only add nodes to immediately cancel — and the log line
carries `grown_nodes` so the drop is visible.
Two review findings on the resources-at-construction change.
argus: `workers::auto_update`'s boot sweep constructs nodes through
`templates::node` too, and it was not converted. With the kind-derived
declaration gone, its sweep `MetaLock` and its per-agent `Reconcile`
silently declared no resources at all — so a boot reconcile no longer
held the agent lease and could race another DAG's container ops, and the
sweep's meta commit could land inside another node's staged deploy
window. Nothing failed to compile: removing an implicit behaviour from a
helper is invisible at every call site that relied on it.
The declarations now live in a pure `boot_nodes`, split out of
`submit_boot_tree` so they can be exercised without a `Coordinator`.
That path is the only place job nodes are built outside `job_queue/`,
which is exactly why it had no coverage; `boot_sweep_nodes_declare_
their_own_resources` closes that, asserting against declared graph edges
rather than against the kind.
mara: `templates::node` is a redundant redirect now that it no longer
derives resources — deleted, and its 43 call sites use `Job::node`
directly. The reasoning it documented moved to the module docs of
`templates.rs` and `resource.rs`, which is where it stays true.
Follows the jobq change: a builder can no longer be constructed or
inserted outside `hive_jobq`, so `DagSpec` cannot hold one. It carries a
`Declare` — `Box<dyn FnOnce(&Job) + Send>` — and the queue runs it
against a builder jobq owns, at the moment it inserts.
`NodeOutput.append_subgraph` becomes `Vec<Declare>` for the same reason,
and this is where the shape was always heading: that field's doc already
said an executor "cannot reach the queue, so it hands the declaration
back", while its type was a `Vec<Job>` the executor had built itself.
The rejected `build_nodes -> Vec<NodeSpec>` was the first version of that
escape hatch; a recipe is the last one, because there is no job-shaped
value to hand over at all.
Templates and the power-op assemblers move their owned data into the
closure and are otherwise unchanged — `rebuild_nodes`, `node` and the
tail helpers already took `&Job` and returned handles, so only each
template's outermost frame moved.
Two `Debug` impls are hand-written: a closure has nothing to show, and
its nodes do not exist until the queue runs it. `NodeOutput` reports how
many subgraphs were emitted, `DagSpec` its source and reason.
`append_subgraph`'s `is_empty()` early-return is gone — you cannot ask a
recipe whether it will declare anything without running it. It now
inserts and returns an empty id list if nothing was declared, which
takes the queue lock in a case that previously skipped it.
The two in-DAG-growth tests build `Declare`s now, so they exercise the
shape an executor actually produces rather than one only a test could
construct. 45 job-queue tests unchanged and passing.
Every template built a `Vec<NodeSpec>` whose edges and parents were
positional indices into that vector, so a shape was expressed as
arithmetic: `base + 1`, `stop_root + 2`, `sfu + 1`, and a
`reconcile_index()` helper that read the emitted vector's length to find
out where its own last node had landed. `concat_subgraphs` existed
solely to rebase one per-agent subgraph's indices onto another's.
Templates now declare into a `hive_jobq::JobBuilder` and hold the
handles they get back, so an edge names the node it waits on. The
arithmetic is gone, and with it:
- `NodeSpec` and the job-queue's own index-based `Dep`.
- `insert_group`'s index resolution — it wraps `Scheduler::insert_job`.
- `concat_subgraphs` — per-agent chains share one builder and each keeps
its own root, so independence is structural rather than computed.
- `reconcile_index` and `dep_index`.
- `templates::validate` and its petgraph toposort. It rejected dangling
deps and cycles; both are now unrepresentable, since a handle only
exists for an already-declared node and every edge therefore points
backwards. (petgraph stays in the tree for `agent_config::topology`.)
`NodeOutput.append_subgraph` becomes `Vec<Job>`: an executor cannot
reach the queue, so it hands back declarations and the scheduler inserts
them under its own lock. That is what the in-DAG growth path always
wanted — a transferable declaration, not a vector of specs.
Resource declaration is unchanged in behaviour: the `templates::node`
helper applies `NodeKind::resource_deps()` at the construction site, so
every node still declares what its kind needs. Moving that declaration
to the call sites is #2818's job; this leaves it one place to delete.
Three tests went with the guard they covered — they hand-built malformed
specs out of indices, which is the representation that made those shapes
possible. Two more now read a DAG's shape off the queue rather than out
of a spec vector, which is where it is observable. The remaining 45
job-queue tests are unchanged and still pass: lease serialization,
roll-up, cancel-cascade, in-DAG growth and per-agent concurrency all
behave as before.
`forge_git_url` spliced `core:<token>@` between scheme and authority, and
that URL is a process argument. `/proc/<pid>/cmdline` is mode 0444 —
world-readable — so the core admin token, which provisions every agent's
forge account, was published to any local user for the lifetime of each
git child. Seven call sites built such a URL.
The credential now travels in the environment instead:
`git_command_authed` sets `http.extraHeader` via `GIT_CONFIG_*`, which
git reads exactly like a config file, and `/proc/<pid>/environ` is 0400 —
owner-only. Same credential, materially smaller audience. The remote is a
plain `http://forge/<org>/<repo>.git`, and `forge_git_url` no longer takes
a token, so the old shape cannot be rebuilt by accident.
`knowledge`'s clone was the one place a credentialed URL was stored as a
named remote — git persists the clone URL into `.git/config`, so the
token sat on disk and every later `pull` authenticated from there. That
is the case `forge::repos::push_config` documents as forbidden ("the
tokenised URL ... deliberately never stored as a named remote"). `pull`
now rewrites `origin` to the plain URL first, which also scrubs the
persisted token from existing deployments, and authenticates from the
environment when a token is available. The repo is public, so the pull
still works without one.
Three call sites also stopped spawning `Command::new("git")` directly,
so they honour the `HYPERHIVE_GIT` path the NixOS module bakes in and
the `kill_on_drop` every other git spawn gets.
The two URL-shape tests now assert the *absence* of a credential, and a
new one decodes the header back to `core:<token>` — without that, a
malformed header would leave every forge operation silently anonymous
with the other assertions still green.
Phase 4 (repoint every container onto `meta#<n>`) and phase 5 (rename
the `root` container to `h-root`) were marker-guarded one-shots for
layouts no live hive still has: containers are rendered onto `meta#<n>`
at creation, and the `h-` prefix has been the naming for far longer than
any deployment predates. A one-shot nobody can still trigger is dead
weight, so both are gone along with `repoint_container`,
`rename_manager_container`, `CONTAINER_TIMEOUT` and the two marker paths.
Phase 6 was not obsolete, only misplaced. Ruth's tool groups are now
seeded by `ensure_root_agent` on the one path that creates her, rather
than re-asserted on every hive-c0re boot. The skip-if-already-set guard
survives the move: a destroy+recreate under the same name must not reset
an operator's chosen group set back to MANAGER_DEFAULT.
That also settles a latent bug. Phase 4's marker check was a `return`,
not a skip, so on any hive carrying the marker phases 5 and 6 never ran
at all — the tool-group backfill, whose whole job was preventing a silent
privilege downgrade, has not executed here in a long time. Moving it to
create-time removes the question rather than answering it.
What stays is convergence: three unguarded, idempotent phases that re-run
each boot and no-op once their state is right. The module doc now names
the three categories so the next person can tell which kind they're
adding.
mara on !2910: "also remove imperative path for the things that are not
nodes yet, file follow up issue to fix that".
`TransientGuard`, the stored map and both manual set/clear are gone.
`transient_snapshot()` is derived and nothing else — destroy and
migration show no pill, because there is no node to derive one from. The
pill returns for free when they become nodes.
What those three guards were actually doing, though, was suppressing the
crash watcher, not drawing a pill. `migrate.rs` said so in its own
comment: without it, `crash_watch` fires `ContainerCrash` for every
migrated agent and the manager tries to recover containers that were
stopped on purpose. Destroy is the same — the container disappears
deliberately and nothing in the graph says so.
Deleting them outright would therefore have traded a dashboard pill for
false crash alerts on every destroy and every migration. So the
suppression survives as its own thing, `suppress_crash_watch`, with a
name that says what it is. It is still RAII, and still held for the
operation rather than stamped once, because the crash watcher's grace
window is finite and a destroy is not — a single tombstone would expire
mid-operation. The drop stamps the tombstone, covering the poll that
lands just after.
That leaves RAII in the codebase for exactly one purpose instead of two.
Untangling the pill from the suppression is what made the transient layer
deletable at all.
Follow-up issue for making destroy + migration real queue nodes to
follow; at that point this guard goes too.
Checked with clippy (`--all-targets -D warnings`), `cargo test -p
hive-c0re -p hive-jobq` (322 + 41 passed) and `nix fmt`.
The dashboard pill was declared once per DAG at submit time, so a rebuild
reported `rebuilding` for its entire life — through the prebuild, the
stop, the swap, the tail and the reconcile. It named the intent of the
request, not what was happening.
It is now read off the nodes actually running. A node lights a pill when
it is `Running` and declares the agent's own resource. Declaring is the
test, not targeting: `Prebuild` and `MetaSync` name an agent but are
lease-exempt on purpose (the container keeps serving), so they must not
light one. It is also not the lease *owner* — `resource_state()` answers
"who holds the slot", which is a different question from "what is
running", and a descendant that borrows an ancestor's grant never
appears in that map.
`TransientKind` is gone entirely rather than being re-derived. The label
is the node's own wire tag (`NodeKind::as_str`) — the same vocabulary
`NodeView.kind` already ships, so a pill and a DAG node name an operation
identically and there is no second taxonomy to keep in step. Work with no
node behind it (destroy, migration) supplies its own literal.
`DagSpec::transient`, `Claim::transient`, `DagMeta::transient` and
`NodeKind::Dag`'s `transient` field all go with it.
## the safety half, which is deliberately not the display half
`crash_watch::is_deliberate_stop` used to match a `TransientKind` to
decide whether a vanished container was intentional or a crash. That made
a pill's display vocabulary decide an alerting question, so renaming or
adding a label would silently move the alerting boundary.
`TransientState` now carries two independent fields: `label` (rendered,
nothing branches on it) and `deliberate_stop` (read only by the crash
watcher). The producer sets the second, because the producer is the only
thing that knows — it is not recoverable from the first.
For queue work that value is `NodeKind::takes_container_down()`, and it
is emphatically not "holds a lease": `Create` and `Start` hold the
agent's lease exactly like `Stop` does, and a container dying *while
starting* is a real crash that must keep reporting as one. The default is
`false` on purpose — a wrong `false` costs a spurious crash event, a
wrong `true` swallows a real crash silently.
## known cost, accepted on the issue
A restart no longer reads `restarting`. No `NodeKind` is unique to a
restart — `restart_chain` reuses `Signal` / `StopForUpdate` / `Drain` /
`Reconcile` — because "restart" is a property of the DAG's shape, not of
any node. A restart now reads `signal` / `stop_for_update`, then the
agent returns.
`Start` / `Stop` / `PostSwap` run inside a lease-holding ancestor and
re-declare nothing, so they light no pill and the agent reads idle for
those windows. Closing that is the resources-where-constructed work
(#2818), not this change.
Checked with clippy (`--all-targets -D warnings`), `cargo test -p
hive-c0re -p hive-jobq` (321 + 40 passed) and `nix fmt`.
Second of the `Dag` field removals, and the same shape as the first:
`DagSpec`/`NodeKind::Dag` carried an `inputs: Vec<String>` that exactly
one node ever read. Both reads live inside `run_meta_lock` — the
`meta::lock_update` call and the `meta_update_cascade_agents` fan-out —
so the list now rides `NodeKind::MetaLock` itself.
The executor stops touching `Claim` for this node entirely: its dispatch
arm already destructured `MetaLock { sweep, fanout }`, so `inputs` joins
them and the `claim` parameter, which had no other use, is gone.
Falls out of that:
- `Claim::inputs` and `DagMeta::inputs` delete.
- `dag_view`'s DAG-level projection onto the `MetaLock` node reads the
payload instead. The wire `NodeView::inputs` is unchanged: still
populated on the `meta_lock` node alone.
- the boot sweep names no inputs (it bumps `hyperhive` alone via
`lock_update_hyperhive`), which the construction site now says out loud
rather than leaving implicit in an empty DAG-level field.
Checked with clippy (`--all-targets -D warnings`), `cargo test -p
hive-c0re` (320 passed) and `nix fmt`. No option surface is touched, so
no nix-eval gate.
`DagSpec`/`NodeKind::Dag` carried an `Option<i64>` approval id that four
deploy phases read back out through `Claim`, via a fallible helper whose
error ("approval deploy dag N has no approval_id") described a state the
type system should have forbidden. Two other templates (`spawn`,
`meta_update`) set the field for nothing: their approval is resolved by
the `ResolveApproval` tails, which already carry the id themselves.
So the id moves onto the nodes that actually need it —
`DeployWindow` / `MergeVerify` / `DeployApply` / `FinalizeDeploy` /
`DeployTail` each take an `i64`, the same way `ResolveApproval` always
has. `templates::approval_deploy` builds all of them in one place with
the value in hand, and `deploy_rebuild_nodes` takes it as a parameter so
the `FinalizeDeploy` it appends at runtime is constructed the same way.
Falls out of that:
- `deploy_approval_id` and its runtime error path delete; each executor
takes the id from its own node payload at dispatch.
- `run_deploy_window` had nothing left to do but validate that id, so the
node joins `Dag` on the shared no-op arm.
- `Claim::approval_id` and `DagMeta::approval_id` delete.
- `dag_view`'s DAG-level projection onto `DeployWindow` reads the payload
instead. The wire `NodeView::approval_id` is unchanged: still set on
the deploy root alone, so the dashboard still renders one approval link
per DAG rather than one per phase.
No option surface is touched, so there is no nix-eval gate here; checked
with clippy (`--all-targets -D warnings`), `cargo test -p hive-c0re`
(320 passed) and `nix fmt`.
The queue carried a per-DAG `HookKind` that fired an inline side effect
from outside the graph when a container rolled up terminal. mara asked
three times why this could not be an ordinary node; the answer in the
code was a doc-comment claiming a node could not work, and it was wrong.
`DepWhen::AfterAny` already existed with two live users, and a weak edge
is satisfied by a `Cancelled` dep, so a tail node runs on success,
failure and cancel alike. What was genuinely missing was smaller than a
hook: a node had no way to learn how the work it followed ended.
So: `Claim` now carries `deps: Vec<DepOutcome>`, snapshotted at claim
time from the graph the scheduler already holds (no `hive-jobq` change).
`Claim::deps_state()` / `deps_error()` roll that up, and two new kinds
consume it — `ResolveApproval { approval_id }` and `EmitRebuilt { agent }`.
Templates append one as a group-root with `AfterAny` edges onto the DAG's
other group roots; a root's state is its subtree's roll-up, so that
covers every node without fanning out to each of them.
Deleted: `HookKind`, `DagSpec.hook`, `NodeKind::Dag.hook`, `DagMeta.hook`,
`TerminalDag`, `terminal_dag()`, `terminal_summary()`, `dag_agents()`,
`dag_rollup()`, `fire_terminal_hook()`, `run_terminal_hook()`,
`emit_rebuilt()`. `complete_node` returns `()`.
Load-bearing details:
- `JobQueue::cancel` spares tail nodes instead of cancelling the whole
subtree, and returns `bool`. Without this a cancelled approval DAG
would dangle its approval forever — the hazard `tests.rs` already
named. The spared tail's deps are `Cancelled`, which satisfies its weak
edge, so the scheduler claims it and it resolves the row as cancelled.
`hive-jobq` anticipated exactly this: `cancel_node`'s doc already says
to settle afterwards so "a weak-edge terminal node observing the
cancellation" can advance.
- The existing `complete(container)` call after cancelling is kept and is
deliberately a no-op when a tail was spared (a non-terminal child parks
the container back in `Finishing`), so power ops still settle
synchronously with no branch.
- `DeployTail` is NOT `is_tail()`: it does real compensating work, and a
cancelled DAG has nothing to compensate.
- `exec::failure_reason` falls back to `first_error(dag_id)` because a
group root that rolled up `Failed` from a child carries no error of its
own — without it every tail-reported failure would lose its reason.
- `EmitRebuilt` is per agent, so a multi-agent DAG reports each agent's
own outcome rather than painting all of them with the DAG roll-up.
- `ResolveApproval` is agentless: the approval row already names its
agent, and that is also what lets one tail close a multi-agent DAG.
Transients-derived-from-running-nodes and the frontend's node-kind
strings stay out of this change; they touch iris's slice and review
better next to their own diff.
