+- `setup/vox_parser.py` reimplements the NetTTS VOX prosody encoder (vendor tags
+  `\!wH1/\!wH0`, `\!br`, `\!sfNN`); the host already passes `TTSDATAFLAG_TAGGED`, so
+  the engine honors them.
+- Validation: the reference `vox_parser.cpp` from a local clone of
+  `h4rm0n1c/NetTTS` was compiled with g++ in a throwaway harness and diffed against
+  the Python port; outputs are identical on the 31-line corpus. Re-check after any
+  parser change while the clone is available.
+- VOX mode is Flextalk-only. The wrapper enables it with `VESKSLOP_TTS_VOX=1`
+  (`VESKSLOP_TTS_VOX_CLEAN=1` drops the stutter wrapper) and it takes precedence
+  over `VESKSLOP_TTS_WORDS`.
+- Line-leading `/rate N` and `/pitch N` controls are consumed by the wrapper
+  (percent, 100 = normal; `<= 2.0` means multiplier). They override the env
+  speed/pitch and are not spoken; a controls-only line yields 100 ms of silence.
