# P3-S22.4 — ML READINESS
```text
Date : 2026-08-26
Session : P3-S22.4 — CORRECTED POPULATION + FEATURE/LABEL CONTRACT VALIDATION
Status : ML READINESS DECISION RECORDED (validation only)
Owner : chiki2bum2 (authoritative repo)
```
## Decision
```text
Corrected-population classification : B — VALIDATED WITH MINOR DOCUMENTED LIMITATIONS
ML readiness : ML-READY
```
## Statement (verbatim)
> P3-S23 — CORRECTED-POPULATION ML BASELINE requires separate owner
> authorization and must use a new pre-registered experiment. P3-S20 remains
> frozen as historical reference.
## What this decision does NOT authorize
This ML-READY determination is **not permission to run ML**. It only records
that the corrected 707-setup population is internally consistent with the
frozen Candidate Setup (F3/F4), feature (12-causal-schema), and label
(P3-S16 v1) contracts, and is sufficiently trustworthy to be a candidate for a
separately authorized corrected-population ML experiment.
## Basis (Parts A–K pass conditions)
```text
A population reproduction : 717/707; shared 484/202/223 match
B candidate-setup contract : verified (0 violations)
C feature schema : 12 features unchanged (schema_sha constant)
D future-injection audit : 12/12
E structural identities : reconfirmed
F label accounting : 707 = 610 + 97 ; class sum == 610
I leakage/mutation : 8/8
K sample-size (corrected) : binary-fit 579 (175 WIN / 404 LOSS)
vs frozen 571 (167 WIN / 404 LOSS)
```
## Statistical caveat (intentionally NOT an ML decision)
The corrected binary-fit N (579) vs the frozen P3-S20 N (571) is a statistical
statement of sample size. It is recorded; it does not by itself declare the
data "sufficient for ML." Sufficiency/power must be stated inside the
authorized P3-S23 pre-registered experiment.
