# s3 — vocabulary self-description breadth

**Protected property:** every closed-vocabulary entry class the binary exposes is
reachable and carries a non-empty one-line meaning, and no entry's meaning is a
byte-identical (non-discriminating) duplicate of a sibling in the same class.

`breadth_probe.sh` drives only `aura` introspection output; `breadth_probe.out`
is its captured result. Run with `AURA=<path-to-release-aura> bash breadth_probe.sh`.

## Result (see breadth_probe.out)
- 33/33 node types resolve via `graph introspect --node <T>` with a
  `"<Name> — <meaning>"` schema. PASS.
- 7/7 folds, 6/6 process blocks, 6/6 campaign blocks, 17/17 metrics reachable and
  carry a meaning (metrics also carry applicability tags). PASS.
- **One blemish:** three distinct node types — `CarryCost`, `ConstantCost`,
  `VolSlippageCost` — share the byte-identical one-liner
  *"cost-model node: charges its cost in R from position geometry, at close or
  accrued per held cycle"*. From `--vocabulary` (the primary discovery surface)
  a consumer cannot tell them apart; the distinguishing detail (the param
  `carry_per_cycle` vs `cost_per_trade` vs `slip_vol_mult`, and the extra
  `volatility` input) lives only in `--node` and in the campaign `cost` slot
  prose. The one-liner exists (C29 satisfied) but is not entry-specific.
