# Locale Drift & Normalization — Guardrails and Fix Pattern
|
||
|
||
A focused fix for **locale-specific normalization bugs** that break retrieval or cause answers to flip between runs. Use this page to align **Unicode form, width, accents, digits, quotes, spaces, casing** across **ingest, index, query, and display**. No infra change required.
|
||
|
||
## Open these first

|
||
* Rerank determinism: [rerankers.md](https://github.com/onestardao/WFGY/blob/main/ProblemMap/rerankers.md)
|
||
|
||
## When to use this page
|
||
|
||
* Same page looks identical to the eye, yet retrieval misses or ranks it differently.
|
||
* Queries with **accented vs unaccented** forms return different snippets.
|
||
* **Half-width vs full-width** characters change similarity scores.
|
||
* **Arabic-Indic digits** or **CJK punctuation** break matches.
|
||
* **Smart quotes** vs straight quotes fragment hits.
|
||
* **Turkish I** or locale-aware casing flips λ between runs.
|
||
* NBSP or narrow spaces split tokens unpredictably.
|
||
|
||
## Core acceptance targets
|
||
|
||
* ΔS(question, retrieved) ≤ **0.45** in the native locale, ≤ **0.50** after cross-locale normalization.
|
||
* Coverage of target section ≥ **0.70** on three paraphrases.
|
||
* λ remains **convergent** across three locale variants of the same question.
|
||
* No analyzer drift between **ingest** and **query** paths in hybrid pipelines.

## 60-second fix checklist
|
||
|
||
1. **Normalize at ingest and query**
|
||
Apply in this order: **Unicode NFC**, width fold, digit fold to ASCII, smart-punct to ASCII, collapse exotic spaces, then **locale-aware casefold**. Keep the original text for display.
|
||
|
||
2. **Dual-key storage**
|
||
Store both `visual_text` and `search_text`. Index BM25 on `search_text`. Keep `visual_text` for citations and display. Schema in [Data Contracts](https://github.com/onestardao/WFGY/blob/main/ProblemMap/data-contracts.md).
|
||
|
||
3. **Embed both views when needed**
|
||
For high-variance locales, create embeddings for **raw** and **normalized** text. Track which path produced the hit inside the snippet payload. See guidance in [embedding-vs-semantic.md](https://github.com/onestardao/WFGY/blob/main/ProblemMap/embedding-vs-semantic.md).
|
||
|
||
4. **Align analyzers**
|
||
Ensure the **same analyzer** and token rules for **ingest** and **query** in hybrid retrieval. Verify with three paraphrases and two seeds. If λ flips, pin headers and apply a BBAM variance clamp.
|
||
|
||
5. **Gold set verification**
|
||
Run a 20-item multilingual gold set. Require ΔS ≤ 0.45 native and ≤ 0.50 normalized, coverage ≥ 0.70, λ convergent.
|
||
|

|
||
|
||
## Minimal adapter spec
|
||
|
||
* Payload must carry: `locale`, `unicode_form`, `width_fold`, `digit_class`, `space_class`, `accent_fold`, `case_mode`.
|
||
* Snippet must include both `visual_text` and `search_text` plus `normalization_trace`.
|
||
* Reject answers if citation `visual_text` and `search_text` disagree on offsets.
|
||
|
||
See schema patterns in [Data Contracts](https://github.com/onestardao/WFGY/blob/main/ProblemMap/data-contracts.md) and tracing in [Retrieval Traceability](https://github.com/onestardao/WFGY/blob/main/ProblemMap/retrieval-traceability.md).

## Copy-paste prompt
|
||
|
||
```
|
||
You have TXT OS and the WFGY Problem Map loaded.
|
||
|
||
My bug smells like locale drift.
|
||
Question variants: {q_native, q_no_accents, q_width_folded}.
|
||
Traces: ΔS_native=..., ΔS_normalized=..., λ states across three variants.
|
||
|
||
Tell me:
|
||
1) which normalization step is missing and why,
|
||
2) the exact WFGY page to open,
|
||
3) the smallest change to push ΔS ≤ 0.45 native and ≤ 0.50 normalized,
|
||
4) a reproducible test with 3 paraphrases and 2 seeds.
|
||
Use BBMC/BBCR/BBAM when relevant.
|
||
```
