Growth enrichment needs a verified Dawn runtime before connecting real developer or account signals. This adds a private, disabled-by-default synthetic research application with a standalone LangSmith artifact, pinned Dawn 0.8.24 dependencies, and the public
growth_researchgraph.The fixed corpus exercises authored plans and skills, a specialist with restricted tools, candidate memory in an explicit pgvector database, and checkpointed parent continuation. Model requests have bounded output, timeout and retries. Packaging excludes environment files and preserves the generated tool schemas; the existing workspace dependency entries are unchanged.
The platform smoke client validates actual tool evidence, reconciles uncertain submissions, and refuses cleanup of active or interrupted runs. No Growth ingestion, account UI or email delivery is connected.
Validation:
npm ci --ignore-scriptson latest main.npx nx run-many -t test,check,lint,build -p growth-research --parallel=1 --skip-nx-cachepassed.Known live-use blocker: Agent Server 0.13.4 can acknowledge interruption before its JavaScript child stops and writes a later checkpoint. Native Dawn cancellation works when supplied a signal, but the server sidecar does not forward it. This limitation is documented and interrupted-thread cleanup fails closed. Independent child session continuation is also unavailable in Dawn 0.8.24; follow-up context must pass through the parent.
Live enrichment remains gated on cancellation/quiescence guarantees, durable work and attempt tracking, trusted account scopes, spending controls, provenance validation and deletion fences.
