build agents only from internal/meta; delete the hive's local meta flake

Browse source 
The hive no longer renders, locks or commits a meta flake. A rebuild's
MetaSync node picks the internal/meta commit and records it with the
hyperhive and config pins it holds; Prebuild, Swap and Create build from it,
and a head that does not pin the agent's current config fails the build
naming the agent. hive-priv's meta_rev is required.

Removed: meta.rs sync/lock/render, the manual-rebuild relock, the boot
sweep's hyperhive bump (MetaLock), the update-meta-inputs form and its
panel, MetaWindow, the hive's hyperhive_rev setting.

Kept: agent_set::refresh holds what sync_agents also did (topology.json, the
gateway's agent-socket map and nginx include), called from spawn, destroy,
rebuild and the migration.

The boot reconcile and the stale-start upgrade compare the agent's marker
with the hyperhive pin of internal/meta; the dashboard's deployed chip reads
the config marker a successful build writes.

`hive-priv` writes them to the container's `/etc/hyperhive-hive-facts` at
start (see `docs/process/conventions.md`).
Containers run against `--flake /var/lib/hyperhive/meta#<n>`, or against
`internal/meta` when it pins the agent ([below](#the-swarms-meta-flake)).
A config that sits only in the hive's `applied/<n>` mirror, not on forge
`main`, never deploys.
The declared input url is the head of `main` on the agent's forge config repo
(`agent-configs/<n>`, the one config PRs merge into), which `sync_agents`
reads at render time. The flake text depends only on those shas and the
agent set, so any machine that can reach the forge resolves it. `sync_agents` fetches
each repo's `main` with the hive's read token (`forge::reader_token()`),
pins its head, and takes the canonical `follows` lines from the
`flake.lock` at that commit. If the forge is unreachable or a repo has no
`main`, `sync_agents` fails for that agent with its name and writes
nothing; there is no fallback to a local path. A config that sits only in
the hive's `applied/<n>` mirror, not on forge `main`, never deploys.
The rebuild paths re-lock the input with `nix flake update agent-<n>` against that
same pinned url, so `flake.nix` and `flake.lock` name no local path.
What `hive-c0re` still keeps under `/var/lib/hyperhive/meta/` is plain
state, bound read-only into the root agent's container as `/meta`:
`topology.json`, the swarm resource limits, and the permission seed files of a
hive that predates the swarm's permissions. `agent_set::refresh(agents:
&[AgentSpec])` keeps `topology.json`, the gateway's agent-socket map and its
nginx include in line with the live agents. `provision_container`, `destroy`,
`rebuild` and the startup migration call it. It refuses an empty agent list,
which means `nixos-container list` failed, and it fails when `HIVE_FORGE_URL`
is unset, since every agent would come up with no forge.
Lock updates are single-phase and commit when the lock changed:
`meta::lock_update_for_rebuild(name)` relocks one agent's input for a
relocking rebuild (the manual `↻ R3BU1LD` button, and the rebuild a
merged config commit queues), and `meta::lock_update_hyperhive()` is the
autoupdate flake-rev bump (one shot before per-agent rebuilds).
`meta::sync_agents(hive: &HiveEnv, agents: &[AgentSpec])` — `hive`
carries `hyperhive_flake`, `dashboard_port`, and the rest of the
per-hive config — is the idempotent reconciler called by `provision_container`,
`destroy`, `rebuild`, and the startup migration. Renders `flake.nix`
from the agent list; if it differs from disk, or `flake.nix` or `flake.lock`
has an uncommitted change (a sync stopped before its commit), runs
`nix flake lock` + commits as `regenerate meta flake` (or
`seed meta from N agent(s)` on the first call). A clean tree whose
`flake.nix` already matches returns without running nix.
The root agent has `/meta` RO-bound inside its container:
`git -C /meta log --oneline` is the swarm-wide deploy log,
`cat /meta/flake.lock | jq '.nodes["agent-<n>"].locked'`
resolves which sha the flake pins each agent at right now.
Dashboard surfaces the same info as a `deployed:<sha12>` chip

The dashboard's `deployed:<sha12>` chip per container row shows the config

## The swarm's meta flake
swarm-controller also commits a meta flake of its own, `internal/meta`, with
the same renderer: one `flake.nix` and `flake.lock` for every agent any hive
places (the pins: [`docs/swarm/builder.md`](../swarm/builder.md#meta-flake-lock)).
A hive builds an agent from it when the repo has a commit that pins the
agent's current config, and from its own meta flake above otherwise, so a hive
older or newer than the controller keeps building.
swarm-controller commits `internal/meta`: one `flake.nix` and `flake.lock` for
every agent any hive places (the pins:
[`docs/swarm/builder.md`](../swarm/builder.md#meta-flake-lock)). A hive builds
every agent from it. While the repo has no commit that pins an agent's current
config, that agent's build fails and names the agent. The controller queues
its update of the repo before the deploy request for a merged config commit
and for a new agent, so a failure here is rare. It sends the deploy even when
that update failed, and the build then fails as described.

Deliberately, **no `GitCommit` node** exists: `meta.rs` fuses each mutation
with its commit under its internal `META_LOCK` mutex, so a standalone commit
node would open a dirty-working-tree window between nodes.
Two further layers protect the meta repo across _windows_ that span multiple
`META_LOCK` acquisitions:
- **The deploy window** (`Resource::MetaWindow`): a global, capacity-1 queue
resource declared by every node kind that mutates the meta repo — `MetaSync`,
`MetaLock` and `Provision`'s agent registration. Two meta
mutations can therefore never interleave, so no commit lands inside another
node's window. It's a queue resource rather than a runtime mutex
because a subtree root holds a resource across its whole subtree, which
a `MutexGuard` (bounded by one executor fn) can't. For the same reason the window must stay
_off_ long store-only work: the rebuild's meta preamble is its own
`MetaSync` node, a sibling of (never a parent of) `Prebuild`, so the
toplevel build runs outside the window and `buildSlots > 1` still gives
concurrent rebuilds across agents.
- **Path-limited commits**: the targeted meta committers (perm files,
topology, lock bumps) commit `-- <their paths>` with path-scoped
dirty checks, so even a non-queue caller (boot migration, destroy's
`sync_agents`) can never sweep someone else's staged content into its
commit.
Nothing in the queue commits to a meta repo: the hive has none to commit to,
and `agent_set::refresh` serializes itself with its own mutex.

doesn't revert the bump). Not child DAGs — one DAG, no `parent_id`. A failed

1. **Config path** — when _any_ marker is stale, submit one `Boot`
DAG: a `MetaLock` (hyperhive input bump, non-fatal) that grows an in-DAG
`Rebuild` subgraph for each stale agent whose `wanted = Up` (name-sorted). Stale but wanted-offline agents get no boot-time nix work — their
rebuild happens on their next start (the start submit path upgrades a
stale start to rebuild+start), which is also why the lock bump runs even
when every stale agent is offline: those later start-upgrades must build
against the bumped lock. Each child rebuild's tail `Reconcile` brings the
agent (back) up, covering both the running-stale and stopped-but-wanted-up
cases.
1. **Config path** — submit one `Boot` DAG holding a graceful `Rebuild`
subgraph for each stale agent whose `wanted = Up` (name-sorted). This is how
a hive that missed the swarm's fan-out catches up. Stale but wanted-offline
agents get no boot-time nix work — their rebuild happens on their next start
(the start submit path upgrades a stale start to rebuild+start). Each
rebuild's tail `Reconcile` brings the agent (back) up, covering both the
running-stale and stopped-but-wanted-up cases. A hive that can't read the
pin (no forge token, the forge down, no `internal/meta` yet) rebuilds
nothing.
2. **Power path** — every agent whose observed state drifted from `wanted`
gets a plain `Reconcile` DAG (`kind = reconcile`, source `auto_update`).
Booting with no config change performs **no meta commit** — only reconciles.
The sweep reason records the rebuild / deferred / up-to-date counts so the
Booting with no pin change performs no rebuild — only reconciles.
The boot log line records the rebuild / deferred / up-to-date counts so the
operator sees at a glance how much work the boot triggered. `auto_update::run`
seeds agents without an `agent_power` row from observed state during
classification (the one-time migration; thereafter the DB is authoritative).
## Meta flake
`meta.rs` owns the single coordinator-managed flake at `/var/lib/hyperhive/meta/`.
This flake consumes every agent's applied config repo as a flake input and exports
one `nixosConfiguration` per agent. Container lifecycle ops drive the lock file so
meta's git log is the system-wide deploy audit trail.
Key operations:
- **`sync_agents`** (idempotent) — render `flake.nix` for the current agent set,
init the repo on first call, relock if the rendered contents changed, commit.
Called by spawn / destroy / startup migration.
- **`lock_update_hyperhive`** — one-shot for the boot-reconcile path (the
sweep DAG's `MetaLock` node): bumps the `hyperhive` input lock and commits;
the scheduler fans out the agent rebuilds on completion.
Every public `meta.rs` operation takes the module's internal `META_LOCK`
mutex, so concurrent job-queue nodes never
race on the repo's `.git/index.lock`.
Each git or nix child under `META_LOCK` has a deadline, so a hung forge fetch
fails the operation instead of holding the lock: 10 minutes for
`nix flake update`/`lock` and forge fetch/push, 2 minutes for local git, including
the `rev-parse` and `show` reads `pin_agents` makes. The error names the command
and the deadline. Each child leads its own process group and the timeout
`SIGKILL`s the whole group, so a `git` or credential helper spawned by a hung
`nix` dies too. A caller waiting on `META_LOCK` for over a minute logs a
`meta_lock: still waiting` warning every minute, naming its own operation and
the holder's. Waiters keep their place in the lock's FIFO queue across warnings.
Agents build from the swarm's `internal/meta` flake, which swarm-controller
commits and every hive reads (see
[Config changes](../agent-lifecycle/config-changes.md#the-swarms-meta-flake)).
The hive keeps no flake of its own. `meta_rev.rs` picks the `internal/meta`
commit an agent builds from and records it; `agent_set.rs` keeps the
host-side files that follow the agent set (`topology.json`, the gateway's
agent-socket map and nginx include) in line with the live agents, and
`meta.rs` keeps the one remaining commit to the legacy `meta/` git repo, the
removal of the permission seed files.
