 5. **Zero trust, provisioned ahead.** Keys are issued per device before deployment; nothing joins the swarm at runtime. Dev channels are physically absent from production builds.
 6. **The whole fleet has one version.** A release manifest pins every image digest, model weight, schema, and config. Rollback is atomic.
 7. **SQL is the contract.** Peer data access is read-only DuckDB SQL over SSH forced commands — the query language already lives on both ends, so no service, port, or protocol is invented for it.
+8. **No debug API.** The bench and the flight use the same channel: an engineer debugging on the ground runs the identical query through the identical wrapper, permissions, and output format a peer drone would use. What you test is what flies.

 The environment engineers live in daily — and deliberately the first thing to build (see [08 — Roadmap](08-roadmap.md)), because everything else is validated inside it.
 
 - **Dev Containers** give every engineer the same toolchain in minutes; no snowflake laptops.
+- **No debug API** ([04](04-swarm-sync.md)): bench access to a drone's data goes through the same read-only SQL-over-SSH wrapper the peers use in flight — same permissions, same statement gate, same columnar output. Debugging exercises the production path instead of a parallel one, so the query channel is regression-tested every working day for free.
 - **The virtual drone fleet** ([`simulator/`](../simulator/)) runs the *identical* data plane: same writer, same partitioning, same sealing, same broadcast schema. `DRONE_COUNT=10 docker compose up` is a swarm on a laptop.
 - **Scenarios are reproducible by seed:** route shapes, sensor noise, drone dropouts, link losses are all parameterized — a bug report is a seed + config, not a war story.
 - **T4 data slices**: a thin tool pulls partition subsets from T3 (`flight=X, drone=Y, hour=Z`) for local work — layout-identical, so every query and pipeline runs unmodified.
