iris 27bed74d42 hive-c0re: accept friendly MemoryMax size spellings, normalize for systemd 
mara hit this directly: setting an agent's memory cap to "16GB"
fails with 'invalid MemoryMax "16GB": expected a size such as
"8G"...'. Confirmed directly against a running systemd 260
(systemd-run -p MemoryMax=<value>): systemd's own parser accepts a
bare byte count, <digits>B, or <digits> plus exactly one uppercase
K/M/G/T, and rejects both "16GB" (redundant B after a multiplier)
and "16g" (lowercase) with "Invalid argument". So the prior
rejection of "16GB" matched systemd, but is bad UX for input a
human reasonably expects to work.

validate_memory_max now returns the value to store (not just an
ok/err verdict): it accepts 8gb/8Gb/8GB/8g/8G interchangeably and
normalizes all of them to systemd's own 8G form before it is ever
persisted or passed downstream. Also fixes the adjacent bug the same
investigation turned up: the old validator incorrectly accepted
lowercase (8g) even though systemd itself rejects it.

Updated both call sites (server.rs, dashboard/lifecycle_ops.rs) to
use the normalized return value. New test
friendly_size_spellings_normalize_to_systemds_own_form; flipped the
old "8GB should be rejected" assertion, which encoded the
human-hostile behavior this fixes.

hive-c0re

The unprivileged host daemon (runs as hive-core). Owns the sqlite broker, the approval/reminder/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, logs, topology).
  • job_queue/ — the job-DAG queue + desired-state reconciliation (docs/scheduler/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/integrations/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.
