iris 78021ce982 docs: fix 329 Microsoft.Contractions hits with proper safety checks
Apply contraction fixes across ~40 doc files (setup, integrations, lifecycle,
networking, scheduler, swarm, tools, trust-boundary, UI, etc.). Skipped 14 hits:
- 10 where words appear in ALL CAPS for deliberate emphasis (is NOT, do NOT, etc.)
- 4 where text could not be safely located due to markdown formatting or column position

Applied via systematic scan with checks for fenced code blocks, inline code spans,
and intentional caps. Preserves sentence-initial capitalization throughout.

Lifecycle and approvals tools

Two tool groups govern agent lifecycle management and config changes. Both are scoped to direct children only (topology-enforced: the server rejects any name that's not a direct child of the calling agent per topology.json). Privileged agents (e.g. ruth) may operate on any sub-agent — the topology scope applies to all others.

lifecycle tool group

No operator approval required. Direct children only.

kill(name)

Graceful stop. Container state is preserved; recreating the agent reuses prior config and credentials.

start(name)

Start a stopped sub-agent.

restart(name)

Stop + start in one call.

update(name)

Rebuild: re-applies the current hyperhive flake + agent.nix, then restarts. Idempotent — safe to call repeatedly. Used in response to needs_update system events.

list_containers()

List all descendant containers (children + their subtrees) with running status. Topology-scoped to descendants only.

approvals tool group

Config changes and new-agent spawns route through the operator approval queue. Direct children only (topology-enforced).

request_init_config(name, description?)

Step 1 of spawning a new direct child agent. Queues an InitConfig approval; on operator approve, hive-c0re seeds the proposed config repo at /agents/<name>/config/agent.nix with a default template and delivers a config_ready system event. Then edit agent.nix, commit, and the operator spawns the agent (the dashboard ◆ R3QU3ST SP4WN button / Spawn approval, routed via HostRequest::RequestSpawn), which creates the container from that config.

Subsequent config changes go through a forge PR on the agent's agent-configs/<name> repo (queues a MergeConfigPr approval on open/update — no MCP tool involved), not a tool call. See docs/agent-lifecycle/approvals.md.

Fails if a proposed config repo for name already exists. name is ≤ 9 characters.

request_update_meta_inputs(inputs?, description?)

Queue an approval to run nix flake update [inputs...] on the meta flake. Pass specific input names (e.g. ["bitburner-agent"]) or omit / pass [] for all inputs. Returns immediately; the lock update runs on operator approval.

Does NOT trigger container rebuilds — call update(name) on affected agents after the approval resolves.

Boundary summary

Operation Requires approval? Scope
kill / start / restart / update No Direct children
list_containers No All descendants
request_init_config Yes (InitConfig) New direct child only
request_update_meta_inputs Yes (MetaUpdate) Meta flake (global)
