Replaces the two overlapping old mechanisms (30-min setTimeout kill in
container-runner, 10-min heartbeat STALE_THRESHOLD reset in host-sweep)
with message-scoped stuck detection anchored to the processing_ack claim
age + an absolute 30-min ceiling that extends for long-declared Bash
tools.
Old model problems:
- IDLE_TIMEOUT setTimeout fired on plain wall-clock time; slow-but-alive
agents got killed at 30min regardless of activity
- 10-min STALE_THRESHOLD in the sweep was unreliable — the heartbeat is
only touched on SDK events, so legitimate silent tool work (sleep 30,
long WebFetch, npm install) looked identical to a hung container
- Two overlapping sources of truth for "when to let go of a container"
New model:
- Host sweep is the single source of truth.
- Container exposes a new `container_state` single-row table in outbound.db
(schema added; container writes, host reads). PreToolUse hook writes
current_tool + tool_declared_timeout_ms (read from Bash's tool_input);
PostToolUse / PostToolUseFailure clear it.
- Sweep decides with a pure helper `decideStuckAction`:
* absolute ceiling — kill if heartbeat age > max(30min, bash_timeout)
* per-claim stuck — kill if any processing_ack row has claim_age >
max(60s, bash_timeout) AND heartbeat hasn't been touched since claim
* otherwise ok
Kill paths reset leftover processing rows with exponential backoff,
reusing the existing retry machinery.
Tool blocklist expanded:
- AskUserQuestion (SDK placeholder; we have mcp__nanoclaw__ask_user_question)
- EnterPlanMode, ExitPlanMode, EnterWorktree, ExitWorktree (Claude Code UI
affordances; would hang in headless containers)
PreToolUse hook is also defense-in-depth: if a disallowed tool name slips
through, it returns `{ decision: 'block' }` so the agent sees a clear
error instead of appearing stuck.
Removed:
- container-runner.ts: IDLE_TIMEOUT setTimeout, resetIdle callback on
activeContainers entry, resetContainerIdleTimer export.
- delivery.ts: the resetContainerIdleTimer call on successful delivery.
- poll-loop.ts: IDLE_END_MS + its setInterval. Keeping the query open is
cheaper than close+reopen (no cold prompt cache). Liveness is now a
host-side concern.
- host-sweep.ts: 10-min STALE_THRESHOLD_MS + getStuckProcessingIds in the
stale-detection path (still exported for kill reset).
Tests:
- src/host-sweep.test.ts — 9 tests for decideStuckAction covering: fresh
heartbeat, absolute ceiling, absent heartbeat, Bash-timeout extension
(both ceiling and per-claim), claim age below tolerance, heartbeat
touched after claim, unparseable timestamps.

v2 ships with only claude baked in. opencode now lives on the `providers`
branch and gets copied in via the /add-opencode skill.
Removed:
- src/providers/opencode.ts
- container/agent-runner/src/providers/{opencode,mcp-to-opencode}.ts + test
- @opencode-ai/sdk from agent-runner package.json + bun.lock
- opencode-ai global install + OPENCODE_VERSION ARG from Dockerfile
- opencode self-registration imports from both provider barrels
- opencode test case from factory.test.ts

Providers now mirror the channels pattern: each module calls
registerProvider() at top level, and providers/index.ts is a barrel of
side-effect imports. createProvider() becomes a thin registry lookup;
the closed ProviderName union is gone (now a string alias, since the
env var is a runtime string anyway).
Also adds a host-side provider-container-registry so providers can
declare their own mounts and env passthrough in src/providers/<name>.ts
instead of the container-runner having to know about each one. The
resolver runs once per spawn and threads provider + contribution
through buildMounts and buildContainerArgs so side effects (mkdir,
etc.) fire exactly once.
Both barrels are append-only — adding a new provider is a new file
+ one import line per barrel, no edits to existing files. The built-in
providers (claude, mock) don't need host-side config, so src/providers/
ships with an empty barrel; the container-side barrel imports both.

Scheduled tasks can now carry a bash script that runs inside the container
before the agent is invoked. The script prints `{wakeAgent, data?}` on its
last stdout line; if `wakeAgent: false` (or the script errors) the task
row is marked completed and the agent is never queried, saving API calls
on no-op checks. On wake, the script's `data` is injected into the task
prompt. Semantics mirror V1: 30s bash timeout, 1MB buffer, last-line JSON,
error == skip.
Also blocks the Claude SDK's built-in scheduling tools (CronCreate,
CronDelete, CronList, ScheduleWakeup) via `disallowedTools` so tasks
actually flow through `mcp__nanoclaw__schedule_task` and get the script
gate. CLAUDE.md gains a soft pointer explaining why `schedule_task` is
the right path.

Reshape AgentProvider so provider-specific assumptions stop leaking into
the generic layer. No change to what reaches sdkQuery() — same values,
different plumbing.
- QueryInput: opaque `continuation` replaces `sessionId` + `resumeAt`;
`systemContext.instructions` replaces ambiguous `systemPrompt`;
`mcpServers`, `env`, `additionalDirectories` move to `ProviderOptions`
at construction time.
- AgentProvider gains `isSessionInvalid(err)` and
`supportsNativeSlashCommands` so the poll-loop stops regex-matching
Claude error strings and gates passthrough slash commands per provider.
- ClaudeProvider owns `CLAUDE_CODE_AUTO_COMPACT_WINDOW` and the
stale-session regex internally.
- ProviderEvent.activity kept and documented as the liveness signal
(fires on every SDK message so the idle timer stays honest during
long tool runs); init carries `continuation` instead of `sessionId`.
- poll-loop drops mcpServers/env/systemPrompt from its config; admin
user id now passed explicitly.

- Replace in-memory Chat SDK state with SqliteStateAdapter — thread
subscriptions now persist across restarts
- Add migration 002 for chat_sdk_kv, subscriptions, locks, lists tables
- Handle /clear in agent-runner (reset sessionId) — SDK has
supportsNonInteractive:false for this command
- Pass /compact, /context, /cost, /files through to SDK as admin commands
- Skip admin commands in follow-up poll so they start fresh queries
- Emit compact_boundary events as user-visible feedback messages
- Pass NANOCLAW_ADMIN_USER_ID and NANOCLAW_ASSISTANT_NAME to containers

- Use DELETE journal mode for session DBs instead of WAL. WAL doesn't
sync reliably across Docker volume mounts (VirtioFS), causing dropped
writes and duplicate deliveries.
- Add 20s idle detection to end the query stream. The concurrent poll
tracks SDK activity via a new 'activity' provider event. When no SDK
events arrive for 20s and no messages are pending, the stream ends
and the poll loop continues.
- Add touchProcessing heartbeat so the host can distinguish active
agents from idle ones by checking status_changed recency.
- Catch query errors in the poll loop and write error responses to
messages_out instead of crashing the process.

AgentProvider abstraction with Claude and Mock implementations.
Poll loop reads messages_in, formats by kind, queries provider,
writes results to messages_out. Concurrent polling pushes follow-up
messages into active queries.
- providers/types.ts: AgentProvider, AgentQuery, ProviderEvent
- providers/claude.ts: wraps Agent SDK with MessageStream, hooks,
transcript archiving
- providers/mock.ts: canned responses with push() support
- providers/factory.ts: createProvider()
- formatter.ts: format by kind (chat/task/webhook/system), XML
escaping, routing extraction
- poll-loop.ts: poll → format → query → write, concurrent polling
- mcp-tools.ts: MCP server with send_message tool
- index-v2.ts: new entry point (config from env, enters poll loop)
- 11 new tests, all 288 tests pass
