# Fixture: readability-self-desc

## 1. Intent

This fixture verifies that the readability lens does NOT fire P2
when the file content is short enough (under the per-artifact
ladder threshold) even when the prose mentions the readability
rule itself.

## 2. Why now

v0.6.3 calibration: per CON-014, the ladder thresholds are
proposal=200, tasks=200, design=600, requirements=400,
constitution=400. This fixture's proposal.md is well under 200,
so the size threshold must not fire.

## 3. Scope

This fixture's proposal.md intentionally mentions the readability
rule inline. The mention is documentation; the lens rule
describes what the lens checks for.

## 4. Success criteria

The lens returns 0 findings on this fixture when run.

## 5. Rollback

N/A — this fixture is read-only.
