@@ -75,6 +75,8 @@ Notes
 - Using resolution: prefer nyash.toml aliases (SSOT). Some tests may enable `NYASH_ALLOW_USING_FILE=1` internally for convenience.
 - Plugin warnings are informational; smokes are designed to pass without dynamic plugins.
 - Harness single-run may take longer due to link+exec; integration profile includes generous timeouts.
+ - Binary selection in scripts: always use `$NYASH_BIN` (the runner sets it to `target/release/hakorune` when present, otherwise falls back to `nyash`).
+ - Branding: user‑visible messages prefer “Hakorune”; the legacy `nyash` binary remains for compatibility but may be gated（`HAKO_ALLOW_NYASH=1`）。
 
 Dev Mode (defaults)
 - In v2 smokes, the `quick` profile exports `NYASH_DEV=1` by default.
@@ -90,7 +92,7 @@ Common commands
 - Focus JSON smokes:
   - `tools/opbox-json.sh` (Roundtrip/Nested, plugins disabled, generous timeout)
 - One-off program (VM):
-  - `target/release/nyash --backend vm --dev apps/APP/main.nyash`
+  - `$NYASH_BIN --backend vm --dev apps/APP/main.nyash`
 
 Key env knobs
 - `NYASH_DEV=1` — enable dev defaults (same effect as `--dev`).
