Additive change — existing code paths still run via inline fallbacks.
Prepares core for per-module extractions in PR #3 onward.
Four registries added with empty defaults:
- delivery action handlers (delivery.ts)
- router inbound gate (router.ts)
- response dispatcher (index.ts)
- MCP tool self-registration (container/agent-runner/src/mcp-tools/server.ts)
Default modules moved to src/modules/ for signaling:
- src/modules/typing/ (extracted from delivery.ts)
- src/modules/mount-security/ (moved from src/mount-security.ts)
Both are imported directly by core — no hook, no registry. Removal
requires editing core imports.
Migrator now keys applied rows by name (uniqueness) so module
migrations can pick arbitrary version numbers. Stored version column
is auto-assigned as an applied-order sequence.
sqlite_master guards added around core calls into module-owned tables
(user_roles, agent_destinations, pending_questions). No-ops today;
load-bearing after the owning modules are extracted.
MODULE-HOOK markers placed at scheduling's two skill-edit sites
(host-sweep.ts recurrence call, poll-loop.ts pre-task gate). PR #4
replaces the marked blocks when scheduling moves to its module.

The dev-agent-in-worktree approach for source self-modification is abandoned
in favor of a direct draft/activate flow with OS-level RO enforcement
(planned, not yet implemented). Strip the whole subgraph:
src/builder-agent/, pending-swaps DB module + migration 006, builder-agent
MCP tools, and all host wiring (startup sweep, approval routing, deadman,
worktree mount, freeze gate). Tool descriptions in self-mod.ts / agents.ts
no longer cross-reference create_dev_agent. CLAUDE.md + v2-checklist updated
to describe the new direction.

Checkpoints the builder-agent dev-agent/worktree/swap flow (create_dev_agent,
request_swap, classifier, deadman, promote) before pivoting to a unified
draft-activate approach with OS-level RO enforcement. Lifts container_config
out of the agent_groups row into groups/<folder>/container.json so install_packages,
add_mcp_server, and rebuild flows can eventually route through the same draft
path as source edits.

Replaces implicit routing context (NANOCLAW_PLATFORM_ID env vars) with
per-agent named destination maps. Agents reference channels and peer
agents by local names; the host re-validates every outbound route against
a new agent_destinations table that is both the routing map and the ACL.
Model changes:
- New migration 004 adds agent_destinations (agent_group_id, local_name,
target_type, target_id). Backfills from existing messaging_group_agents.
- Host writes /workspace/.nanoclaw-destinations.json before every container
wake so admin changes take effect on next start.
- Container loads map at startup, appends system-prompt addendum listing
available destinations and the <message to="name">…</message> syntax.
- Agent main output is parsed for <message to="..."> blocks; each block
becomes a messages_out row with routing resolved via the local map.
Untagged text and <internal>…</internal> are scratchpad (logged only).
- send_message MCP tool now takes `to` (destination name) instead of raw
routing fields. send_to_agent deleted (redundant — agents are just
destinations). send_file/edit_message/add_reaction route via map too.
- Inbound formatter adds from="name" attribute via reverse-lookup so the
agent sees a consistent namespace in both directions.
Permission enforcement:
- Host checks hasDestination() before every channel delivery AND every
agent-to-agent route. Unauthorized messages dropped and logged.
- routeAgentMessage simplified: ~15 lines, no JSON parse, content copied
verbatim (target formatter resolves the sender via its own local map).
- create_agent is admin-only, checked at both the container (tool not
registered for non-admins) and the host (re-check on receive). Inserts
bidirectional destination rows so parent↔child comms work immediately.
Includes path-traversal guard on folder name.
Self-modification cleanup:
- add_mcp_server now requires admin approval (previously had none).
- install_packages validates package names on BOTH sides (container tool
+ host receiver) with strict regex. Max 20 packages per request.
- All three self-mod tools are fire-and-forget: write request, return
immediately with "submitted" message. Admin approval triggers a chat
notification to the requesting agent — no tool-call polling, no 5-min
holds. On rebuild/mcp_server approval, the container is killed so the
next wake picks up new config/image.
- Approval delivery extracted into requestApproval() helper (the one
place where three call sites were literally identical).
Also folded in the phase-1 dynamic import cleanup (create_agent no longer
does `await import('./db/agent-groups.js')`) and removes NANOCLAW_PLATFORM_ID
/ CHANNEL_TYPE / THREAD_ID env-var routing entirely.
