 ## What this is
 
-The **endocrine array** — slow-signal organs that modulate the system: the R
-**Drive-Box** (`drive_box.R`, `driver_*.R`, `endocrine_array.R`, `priors.R`) and
-the Octave **ETR** under `etr/`. See `Plan.md` here and `etr/etr_invariants.md`
-for design.
+The **endocrine array** — strong-signal organs that modulate the system: the **Drive-Box** (`drive_box.R`, `driver_*.R`, `endocrine_array.R`, `priors.R`) and it's **ETR** under `etr/`. See `Plan.md` here and `etr/etr_invariants.md` for design principles.
 
 ## Build & run
 
 Toolchains (R 4.3.3, Octave 8.4) are installed each session by the SessionStart
-hook. Run the organ tests directly:
-
-```bash
-src/endocrine/run_tests.sh        # R Drive-Box + drivers
-src/endocrine/etr/run_etr_tests.sh   # Octave ETR
-```
-
-(Not yet wired into the top-level `run-sica-fondt` smoke driver — run them here.)
+hook.
 
 ## Local notes
 
-- Pure R/Octave; no compile step. Each `test_*.R` / `test_etr.m` pairs with its
-  `driver`/source file.
-- ETR invariants are documented in `etr/etr_invariants.md` — read before
-  changing `etr.m`.
