# P3-S22.3 — REPAIR DECISION
|

|
Session : P3-S22.3 — RESEARCH M30 CONSTRUCTION REPAIR & POPULATION REDERIVATION
|
|
Status : COMPLETE (research-only; corrected construction implemented and verified)
|
|
Policy : docs/CODE_VERIFICATION_AND_SILENT_BUG_POLICY_v1.md
|
|
Decision : C — CORRECTION VERIFIED, MATERIAL POPULATION CHANGE
|
|
```
|
|
|
|
## Question
|
|
|
|
> Can the research-side M30 construction be corrected to match the verified
|
|
> UTC-clock runtime semantics, and what exact change does that correction make
|
|
> to the historical Candidate Setup population and the frozen feature/label
|
|
> rows?
|
|
|
|
Answer: YES. The corrected UTC-clock M30 construction matches the independent
|
|
oracle 100 %, the frozen baseline is reproduced (694 created / 686 in-scope),
|
|
and the material population change is quantified below.
|

## Classification
|
|
|
|
```text
|
|
C — CORRECTION VERIFIED, MATERIAL POPULATION CHANGE.
|
|
```
|
|
|
|
Evidence base:
|
|
- Independent oracle: 100 % agreement on timestamps / open / high / low /
|
|
close / dirs / gate.
|
|
- Frozen baseline: 694 / 686 / 0 per-bar mismatch (reproduced).
|
|
- Mutation: 6/6 detected; regression: 12/12 invariant.
|
|
- Part D test suite run twice, byte-identical.
|
|
- Population change: 686 -> 707 in-scope; 202 old identities not reproduced;
|
|
223 different identities appear; M30 gate differs on ~19.5 % of bars.
|
|
|
|
## Not changed
|
|
|
|
```text
|
|
Production MQL5 : NO (verified by git).
|
|
F1/F2/F3/F4 / labels / FEATURE_CONTRACT / TP-SL-horizon : NO.
|
|
ML : NO (no retrain, no recalibrate, no nonlinear, no tune).
|
|
Historical P3-S16..P3-S22 artifacts : NO (additive only).
|
|
External data : NO (no Tickstory / Dukascopy).
|
|
Deployment / trading : NO (no live trade).
|
|
```
|
|
|
|
## ML gate
|
|
|
|
This phase did NOT retrain or re-evaluate ML. Because the corrected population
|
|
differs materially:
|
|
|
|
> P3-S20 remains a valid historical result for the frozen historical
|
|
> population, but a new corrected-population ML experiment is required before
|
|
> making any claim about model performance on the corrected dataset.
|
|
|
|
That new experiment is NOT performed automatically; it requires a separate
|
|
authorized phase (P3-S22.4). Production MQL5 is not defective (the runtime
|
|
already reads the broker UTC-grid M30); the repair is confined to the
|
|
historical RESEARCH chain.
