Replace the per-group "written once at init, owned by the group" CLAUDE.md
with a host-regenerated entry point that imports:
- a shared base (`container/CLAUDE.md` mounted RO at `/app/CLAUDE.md`)
- optional per-skill fragments (skills that ship `instructions.md`)
- optional per-MCP-server fragments (inline `instructions` field in
`container.json`)
- per-group agent memory (`CLAUDE.local.md`, auto-loaded by Claude Code)
Principle: RW = per-group memory, RO = shared content. Source/skills/base
are shared; personality, config, working files, and Claude state stay
per-group.
Key changes:
- New `src/claude-md-compose.ts` — per-spawn composition +
`migrateGroupsToClaudeLocal()` one-time cutover.
- New `container/CLAUDE.md` — shared base, seeded verbatim from the
former `groups/global/CLAUDE.md`.
- `src/container-runner.ts` — swap `/workspace/global` mount for RO
`/app/CLAUDE.md`; call `composeGroupClaudeMd()` after
`initGroupFilesystem()`.
- `src/group-init.ts` — drop `.claude-global.md` symlink + initial
`CLAUDE.md` write; seed `CLAUDE.local.md` from `opts.instructions`.
- `src/index.ts` — call `migrateGroupsToClaudeLocal()` at startup.
- `src/container-config.ts` — add optional `instructions` field to
`McpServerConfig` (inline per-MCP guidance fragment).
- `container/Dockerfile` — drop dead `/workspace/global` mkdir.
- Remove obsolete `scripts/migrate-group-claude-md.ts`.
Migration (runs once at host startup, idempotent):
- Delete `.claude-global.md` symlinks in each group.
- Rename each `groups/<folder>/CLAUDE.md` → `CLAUDE.local.md`
(preserves existing per-group content as memory).
- Delete `groups/global/` directory.
Design docs: `docs/claude-md-composition.md` and `docs/shared-source.md`
(the latter is the sibling design discussion this refactor builds on).

Replace the per-group agent-runner-src copy model with a single shared
read-only mount. Source and skills are now RO + shared; personality,
config, working files, and Claude state stay RW + per-group.
Key changes:
- Mount container/agent-runner/src/ RO at /app/src (all groups share one copy)
- Mount container/skills/ RO at /app/skills; per-group skill selection via
symlinks in .claude-shared/skills/ based on container.json "skills" field
- Mount container.json as nested RO bind on top of RW group dir
- Move all NANOCLAW_* env vars to container.json (runner reads at startup)
- New runner config.ts module replaces process.env reads
- Move command gate (filtered/admin) from container to host router
- Dockerfile: remove source COPY, split CLI installs (claude-code last),
move agent-runner deps above CLIs for better layer caching
- Add writeOutboundDirect for router denial responses
- Design doc at docs/shared-src.md
Not included (follow-up): DB migration to drop agent_provider columns,
cleanup of orphaned agent-runner-src directories.

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.

Claude Code's @-import directive only follows paths inside the project
memory tree (cwd + ancestors). Both `@/workspace/global/CLAUDE.md` and
`@../global/CLAUDE.md` are silently ignored because `/workspace/global`
is outside `/workspace/agent` (the cwd). The import line is parsed but
the content is never loaded — validated with a sentinel passphrase test
against a live container.
Fix: drop a `.claude-global.md` symlink into each group's dir pointing
at `/workspace/global/CLAUDE.md`. The link path is absolute on container
terms (dangling on host, valid via the /workspace/global mount) and the
symlink file itself is inside cwd, so Claude's @-import is happy. The
group's CLAUDE.md imports via `@./.claude-global.md`.
- src/group-init.ts: initGroupFilesystem now drops the symlink (idempotent,
uses lstat so existsSync doesn't trip on the dangling target on the
host). Default CLAUDE.md body uses `@./.claude-global.md`.
- scripts/migrate-group-claude-md.ts: creates the symlink for existing
groups and rewrites any broken `@/workspace/global/CLAUDE.md` or
`@../global/CLAUDE.md` import line to `@./.claude-global.md`.
- groups/main/CLAUDE.md: migration rewrote the import.
Validated: live container with the symlinked import correctly surfaces
global CLAUDE.md content (passphrase `quinoa-submarine-42` added to
global, retrieved via claude -p, removed).

Each group's on-disk state (CLAUDE.md, .claude-shared/, agent-runner-src/)
is now initialized exactly once at group creation and owned by the group
forever after. Spawn does only mounts — no copies, no settings.json
overwrites, no skill clobbers, no source resyncs.
Global memory composition switches from "host reads /workspace/global/CLAUDE.md
at bootstrap and stuffs it into systemPrompt.append" to "group CLAUDE.md
imports it via @/workspace/global/CLAUDE.md at the top." Edits to global
propagate instantly through the existing read-only mount; no copy, no
restart.
- src/group-init.ts: new initGroupFilesystem(group, opts?) — idempotent,
populates groups/<folder>/, .claude-shared/, agent-runner-src/ only when
paths don't already exist.
- src/container-runner.ts: buildMounts() calls init defensively at the
top (catches existing groups on first spawn after this change), drops
the inline settings.json write, skills cpSync loop, and agent-runner-src
rm-then-copy. Just mounts now.
- src/delivery.ts: create_agent flow uses initGroupFilesystem with
optional instructions, replacing the inline mkdirSync + writeFileSync.
- container/agent-runner/src/index.ts: drops GLOBAL_CLAUDE_MD reading.
systemContext.instructions is now only the runtime-generated
destinations addendum.
- scripts/migrate-group-claude-md.ts: one-shot migration that prepends
the @-import to existing groups' CLAUDE.md. Skips if global doesn't
exist or if the @-import is already present (regex match on the @ form
to avoid false positives from prose mentions of the path).
- groups/main/CLAUDE.md: prepended by the migration.
Existing groups need a one-time wipe of their agent-runner-src/ dir so
init re-populates from current host source — done locally before this
commit. Future host-side updates to container/skills/ or
container/agent-runner/src/ won't auto-propagate; that's the trade-off
for unconditional persistence and will be covered by host-mediated
refresh tools in a follow-up.
