Summary

The embedded Pi orchestrator (OpenClaw's in-process LLM runner) was gutted but its call sites remain with undefined-returning stubs. These stubs silently no-op code paths that should either be removed or replaced with RemoteClaw's CLI runtime equivalents.

Production stubs (10 across 6 files)

src/auto-reply/reply/agent-runner.ts

• Line 7 — queueEmbeddedPiMessage stub (always returns false)
• Line 221 — call site: queueEmbeddedPiMessage(...) — dead steering logic (stub returns falsy, so steered is always false)

src/auto-reply/reply/get-reply-run.ts

• Line 5 — abortEmbeddedPiRun stub (always returns false)
• Line 6 — isEmbeddedPiRunActive stub (always returns false)
• Line 7 — isEmbeddedPiRunStreaming stub (always returns false)
• Line 8 — resolveEmbeddedSessionLane stub (formats a session lane key)
• Lines 441–450 — call sites: abortEmbeddedPiRun, isEmbeddedPiRunActive, isEmbeddedPiRunStreaming, resolveEmbeddedSessionLane

src/agents/tools/subagents-tool.ts

• Line 30 — abortEmbeddedPiRun stub (returns undefined)
• Line 250 — call site: abortEmbeddedPiRun(sessionId)
• Line 617 — call site: abortEmbeddedPiRun(sessionId)

src/auto-reply/reply/commands-session.ts

• Line 21 — handleAbortTrigger stub (async no-op)
• Line 23 — handleStopCommand stub (async no-op)
• Line 474 — exports: handleAbortTrigger, handleStopCommand

src/gateway/server-reload-handlers.ts

• Line 2 — getActiveEmbeddedRunCount stub (always returns 0)
• Line 167 — call site: getActiveEmbeddedRunCount()

src/gateway/server.impl.ts

• Line 4 — getActiveEmbeddedRunCount stub (always returns 0)
• Line 434 — call site: getActiveEmbeddedRunCount()

src/auto-reply/reply/queue/cleanup.ts

• Line 2 — resolveEmbeddedSessionLane stub (duplicate of the one in get-reply-run.ts)
• Line 28 — call site: resolveEmbeddedSessionLane(cleaned)

Config schema entries (4 files)

• src/config/types.agent-defaults.ts:182 — embeddedPi? type field
• src/config/zod-schema.agent-defaults.ts:116 — embeddedPi Zod schema
• src/config/schema.help.ts:954–956 — help text for agents.defaults.embeddedPi and agents.defaults.embeddedPi.projectSettingsPolicy
• src/config/schema.labels.ts:430–431 — labels for agents.defaults.embeddedPi and agents.defaults.embeddedPi.projectSettingsPolicy

Test files (8 files with embeddedPi mocks)

• src/auto-reply/reply/agent-runner.runreplyagent.e2e.test.ts — runEmbeddedPiAgentMock (41 references)
• src/auto-reply/reply.directive.directive-behavior.e2e-harness.ts — runEmbeddedPiAgent mock export
• src/auto-reply/reply.directive.directive-behavior.applies-inline-reasoning-mixed-messages-acks-immediately.test.ts — runEmbeddedPiAgent assertions
• src/auto-reply/reply.triggers.trigger-handling.targets-active-session-native-stop.e2e.test.ts — getCompactEmbeddedPiSessionMock, getAbortEmbeddedPiRunMock, runEmbeddedPiAgentMock (26 references)
• src/auto-reply/reply.heartbeat-typing.test.ts — runEmbeddedPiAgentMock import and usage
• src/agents/subagent-announce.format.e2e.test.ts — isEmbeddedPiRunActive, isEmbeddedPiRunStreaming, queueEmbeddedPiMessage, waitForEmbeddedPiRunEnd mocks (46 references)
• src/cron/isolated-agent/run.test-harness.ts — runEmbeddedPiAgentMock (3 references)
• extensions/test-utils/plugin-runtime-mock.ts — runEmbeddedPiAgent: noopAsync

What to do

Remove each stub and its surrounding call site. The queueEmbeddedPiMessage call in agent-runner.ts:221 is a dead code block (stub returns false, so steered is always falsy). The abort/stop stubs disable those commands entirely. The getActiveEmbeddedRunCount stubs always return 0, making them no-ops in the busy-wait and drain logic. Clean up config schema entries and rename test mocks to reflect the CLI runtime bridge.

Files NOT in scope (verified: zero embeddedPi references)

• src/auto-reply/reply/abort.ts — no embeddedPi refs
• src/gateway/server-methods/sessions.ts — no embeddedPi refs

Acceptance Criteria

• grep -ri "embeddedPi" src/ extensions/ returns zero matches
• pnpm check passes
