atlas 5c5c8776d2 refactor(#2802): cancelling a DAG is a scheduler operation 
`JobQueue::cancel` decided whether a DAG could be cancelled by reading node
run-state, walked the subtree, judged per node whether that node had asked
to observe cancellation, and re-ran the container's roll-up. Every one of
those is a fact the scheduler owns; core was reaching across the boundary
to compute them.

`Scheduler::cancel_node` now takes the whole subtree: cancelling a node
cancels the work under it, since a group is abandoned by abandoning its
root. The existing method generalises rather than gaining a sibling — it
had one production caller, which this replaces.

The gate runs over the work *under* the node, not the node itself: a group
root's state is its subtree's roll-up rather than a step that ran, so a
container is `Finishing` and never `Pending`, and gating on it would refuse
every cancel. A node with no children is its own work, which keeps the
previous single-node behaviour.

`observes_cancellation` moves in with it — it reads a node's declared edges
and knows nothing about what the payload means.

Core keeps the one genuinely domain-specific step, resolving a wire
`dag_id` to its container node, and is three lines otherwise.

hive-c0re

The unprivileged host daemon (runs as hive-core). Owns the sqlite broker, the approval/question/schedule queues, the generic job-DAG queue, container lifecycle, gateway/forge/matrix provisioning, per-container stats, and the axum operator dashboard. Largest crate in the workspace — bin-only, no separate lib.

When to use it

Host-level, cross-container orchestration: spawning/rebuilding/ destroying agent containers, the approval flow, dashboard-visible state, provisioning per-agent forge/matrix/gateway accounts. Agent-side behavior (turn loop, MCP tools) lives in hive-agent/hive-agent-mcp instead — this daemon only talks to agents over the socket wire types in hive-sh4re.

Shape

Cohesive clusters live in directory submodules, each re-exported at the crate root (crate::broker::… keeps resolving regardless of which subdirectory a module actually lives in). One line each — read the module's own //! doc-comment for real detail, don't expect this file to track it:

  • dashboard/ — the operator dashboard (containers, approvals, schedules, questions, logs, topology).
  • job_queue/ — the job-DAG queue + desired-state reconciliation (docs/coordinator.md).
  • lifecycle/ — nixos-container lifecycle + per-agent config flake generation.
  • stores/ — sqlite-backed stores (broker, queues, audit, power).
  • workers/ — background sweeps (crash watch, scheduled prompts, auto-update, knowledge sync).
  • agent_config/ — per-agent registries (tool groups, capabilities, resource limits, topology).
  • stats/ — dashboard metrics aggregation + OTEL export.
  • socket_server/ — the unix-socket request server shared by per-agent + manager sockets.
  • forge/ — optional Forgejo wiring (docs/forge.md).
  • coordinator.rs — top-level wiring for serve.
  • meta.rs, migrate.rs — the meta flake + schema/state migrations.
  • matrix.rs, gateway_nginx.rs, webhook_secret.rs, priv_client.rs — matrix provisioning, gateway vhosts, webhook secrets, and the hive-priv client respectively.
