🏥 Quick Return to Emergency Room

You are in a specialist desk.
For full triage and doctors on duty, return here:

• WFGY Global Fix Map — main Emergency Room, 300+ structured fixes
• WFGY Problem Map 1.0 — 16 reproducible failure modes

Think of this page as a sub-room.
If you want full consultation and prescriptions, go back to the Emergency Room lobby.

Stabilize multilingual RAG and reasoning across CJK, RTL, Indic, Latin, emoji, and locale variants.
This hub localizes language-layer failures and routes you to the exact structural fix. No infra change required.

What this page is

• A compact language-aware repair guide for retrieval → ranking → reasoning.
• Structural fixes with measurable acceptance targets.
• Store-agnostic. Works with FAISS, Redis, pgvector, Elastic, Weaviate, Milvus, and more.

---

When to use

• Corpus spans CJK or Indic scripts and retrieval keeps missing the correct section.
• Queries code-switch or mix scripts, and top-k order drifts across runs.
• Accents/diacritics or fullwidth/halfwidth forms break matching or citations.
• RTL punctuation or control chars flip token order or offsets.
• Token counts jump after deploy even though data did not change.

Acceptance targets

• ΔS(question, retrieved) ≤ 0.45 on three paraphrases
• Coverage of target section ≥ 0.70
• λ remains convergent across two seeds
• Tokenization variance for the same query ≤ 12% across environments
• Normalization pass rate for NFKC + width + diacritics ≥ 0.98

---

Fix in 60 seconds

1. Normalize once, up front → Apply NFKC, collapse fullwidth/halfwidth, unify diacritics.
2. Match tokenizer and analyzer → Same segmenter for CJK/Indic across embed + store analyzers.
3. Stabilize mixed-script queries → Detect code-switch, split per script, rerank deterministically.
4. Verify → ΔS ≤ 0.45, Coverage ≥ 0.70, λ convergent across two seeds.

FAQ (Beginner-Friendly)

Q1: Why do answers break when I mix English and Chinese in one query?
A: Most vector stores tokenize differently by script. Without alignment, Chinese words get split incorrectly and English tokens dominate. Fix with script_mixing.md and tokenizer_mismatch.md.

Q2: What does “locale drift” mean?
A: Locale drift happens when environments use different analyzers (e.g., zh_TW vs zh_CN) so the same query splits differently. See locale_drift.md.

Q3: Why do “identical-looking” characters not match?
A: They may differ in width (fullwidth vs halfwidth), normalization (NFKC vs NFD), or diacritics. Always apply unicode_normalization.md and digits_width_punctuation.md.

Q4: How do I handle Arabic or Hebrew text?
A: RTL scripts can insert invisible bidi control chars that flip token order. See rtl_bidi_control.md.

Q5: Do I need different embeddings for each language?
A: No. You can combine multilingual embeddings with deterministic normalization and alias fields. If that fails, only then use fallback translation bridges.

Q6: How do I debug when results change between environments?
A: Compare tokenizer version, analyzer settings, normalization passes, and collation rules. Document them in data-contracts.md.
