# Round 04 Blind Input Set

Source: `selector/round04_blind_inputs.json`

Human-readable source: `reports/Round04_blind_input_candidates_2026-06-18.md`

Status: `frozen_for_first_blind_run_after_owner_review`

## 1. Blindness Rules

- No expected routing labels are included.
- Category labels are coverage labels, not answer keys.
- The input pool must not be merged into `selector/selector_calibration_inputs.json` before review.
- Selector rules must not be modified before the first blind run.

## 2. Count

Total inputs: 38

Control notes:

- `R04-BI-018`: positive control for obvious model-extraction / depth-modeling intent.
- `R04-BI-021`: model-name-exposed control case.
- `R04-BI-025`: model-name-exposed control case.
- `R04-BI-026`: high-value natural boundary sample, because it avoids explicit model names while suggesting IA or QPI-to-IA routing.

## 3. Category Coverage

- explicit no-call fact / translation / rewrite / formatting / direct execution
- ordinary how-to no-call traps
- dictionary / word-meaning judgment no-call trap
- QPI lightweight problem definition
- governance / responsibility / consensus
- capacity / resource / path
- model extraction / depth modeling
- IA refused but QPI allowed
- depth-limiting but QPI allowed
- likely Intellectual Archaeology
- ambiguous / low context
- ambiguous growth how-to boundary
