## Summary
Behavior-preserving cleanup ahead of the H3 flow-fix work (see
`.claude/plans/nrs_h3_fix_plan.2.md`, fact 8 / Phase 3 / Sequencing
PR-1). No output change — pure refactor plus a regression net.
### Changes to `NRS/nodes_NRS.py`
- **Removed the broken name-mangling guard.** `hasattr(self,
"__pred_type")` checked the literal name while assignment created
`_NRS__pred_type`, so the guard never fired. `patch()` now computes
`pred_type = self._get_pred_type(model)` unconditionally and passes it
as a closure local / explicit parameter into `nrs()`,
`_convert_to_v_space`, and `_finalize_from_v_space`. This preserves the
(correct) always-redetect behavior and removes a latent cross-model
aliasing bug. The `hasattr` string was **not** "repaired" — doing so
would introduce a stale-cache bug since ComfyUI reuses node instances
across queue runs.
- **Amputated dead operation-space arms.** `self.__OPERATION_SPACE` was
hardcoded to `PredictionType.V`, making both `match` blocks and the
`_convert_to_eps_space`/`_finalize_from_eps_space` helpers unreachable.
Removed them; the `nrs()` hook now calls the V-space
conversion/finalization directly. The inner V-vs-EPS conversion math
inside the V-space helpers is untouched — that is the real per-model
algebra, not dead code. FLOW is added in a later PR.
### Tests
- New `tests/test_pred_type.py`: parametrized coverage of all 11
`_RAW_TO_ENUM` entries plus `_get_pred_type` walks over stub models
(direct-attribute path and enhanced-detection fallback). These pin
**current** behavior (flow-family → EPS) as a regression net for the
FLOW reclassification PR.
## Verification
- `24/24` tests pass (21 new + 3 pre-existing smoke) from a clean
checkout.
- Greps for `self.__pred_type`, `_NRS__pred_type`,
`self.__OPERATION_SPACE` all empty.
- Diff: `NRS/nodes_NRS.py` +16/-87, `tests/test_pred_type.py` +111 —
behavior-preserving, well under 500 LoC.
