 ## 🌟 New Features
 
-- **Runtime liveness watchdog and a tokio-console diagnostic build.** An optional heartbeat/watchdog detects a wedged
+- **Runtime liveness watchdog.** An optional heartbeat/watchdog detects a wedged
   async runtime (process alive, scheduler no longer making progress, logs stop) and logs a diagnostic snapshot with
   runtime metrics and a per-thread `/proc/self/task` inventory. It is opt-in and off by default (`TULIPROX_WATCHDOG=1`
   to observe, `=2` to also restart the process on a confirmed stall), and exposes its state through the `/healthcheck`
-  `runtime` object. For deeper task and lock inspection, `make build-diagnostic` produces a separate `tokio-console`
-  binary; normal release images contain neither the subscriber nor `tokio_unstable`.
+  `runtime` object.
 
 - **`.env` file support for secrets and environment variables:** Tuliprox now automatically loads environment variables
   from a `.env` file at startup.

-### Diagnostic Build (tokio-console)
-
-To diagnose async hangs (tasks that never complete, locks held across `.await`), build the diagnostic binary:
-
-```bash
-make build-diagnostic
-TULIPROX_TOKIO_CONSOLE=1 ./target/release/tuliprox -s -p ./config
-tokio-console            # defaults to http://127.0.0.1:6669
-```
-
-This build compiles `tokio` with `--cfg tokio_unstable` and enables the optional `console-subscriber`. It is a separate
-binary and normal release builds are unaffected. The experimental Docker image
-(`ghcr.io/euzu/tuliprox:experimental`) is built this way and enables the subscriber by default. See
-[Runtime Liveness Watchdog](./operations-debugging.md#8-runtime-liveness-watchdog) for the always-available (opt-in)
-watchdog that does not require a special build.
-
 ### Cross-Compilation (ARM / Windows)
 
 To compile for architectures other than your host, use the `cross` tool or native mingw packages.

 `runtime.status` is `stalled` once the heartbeat stops. The top-level `status` intentionally stays `ok` for as long as the
 HTTP server answers, so no orchestrator restarts the process. If the whole runtime is wedged, the endpoint cannot answer
 at all — in that case the watchdog log is the signal.

-## 9. tokio-console Diagnostic Build
-
-`tokio-console` shows live which tasks exist, where each one is waiting, and which lock it holds. It is the tool to
-identify an async deadlock. It needs a special build and is never part of the standard production image.
-
-```bash
-# Build the diagnostic binary (requires RUSTFLAGS="--cfg tokio_unstable" internally)
-make build-diagnostic
-
-# Run it with the subscriber enabled and attach the console
-TULIPROX_TOKIO_CONSOLE=1 ./target/release/tuliprox -s -p ./config
-tokio-console            # defaults to http://127.0.0.1:6669
-```
-
-The experimental Docker image (`ghcr.io/euzu/tuliprox:experimental`) already carries this build and enables it by default.
-
-Notes:
-
-* The default release build compiles none of this: no `tokio_unstable`, no `console-subscriber`. There is no runtime cost
-  in normal images.
-* The console gRPC server has no authentication. Keep it on loopback (the default) or, if you must publish a port,
-  publish it only on the host loopback (`-p 127.0.0.1:6669:6669`).
