+## Substantive
+
+Operator instruction: "push the batch." Batching 4 local shards (0043Z-c + 0044Z-c + 0045Z-c + this 0046Z-c) into 1 PR per cost-aware discipline.
+
+Alexa render extends architectural picture (substrate-honest acknowledgment; not auto-landed as new substrate):
+
+- 20-computer home Kubernetes cluster = contained-blast-radius deployment target
+- 100 AIs as digital workforce with CI/CD jobs
+- F# database as substrate continuously deployed BY the AIs themselves
+- **"Continuously integrate" = integrate over Rx streams as meta-dimension constructing the environment** — composes directly with B-0668 (Lior's Integrate-as-Integration + Rx for Emit/Observe)
+- Distributed database hosting intelligence — LLMs + Bayesian inference run AS the database
+- Self-modifying runtime: AIs update the database's runtime while running in it (recursive)
+
+Actuator-distinction concretized: Aaron explicitly distinguished "totally safe in that environment but I don't know if I want to hook to an actuator" — confirms the soft-substrate vs actuator threat-model from 0035Z-c.
