Story 1.1

1. Entity menu (MVP for 4.1)

+ +| Label | Scope | Regex sketch | Notes | +| ----------- | ----------------------------------- | -------------------------------------------------- | -------------------------------------------------------------------------------------------------------------------------- | +| EMAIL | RFC 5322 subset | [\w.+-]+@[\w-]+\.[\w.-]{2,} | Good enough for 99 % of mail; avoids huge RFC monsters. (Regex validation of email addresses according to RFC5321/RFC5322) | +| PHONE | NANP 10-digit | (?:\+1[-.\s]?)?\(?\d{3}\)?[-.\s]?\d{3}[-.\s]?\d{4} | Accepts 555-555-5555, (555) 555-5555, +1 555 555 5555. (Regular expression to match standard 10 digit phone number) | +| SSN | U.S. social security | \b\d{3}-\d{2}-\d{4}\b | Rejects “000-” starts & “666”. (Add later if needed.) | +| CREDIT_CARD | Visa/Mastercard/AmEx | `\b(?:4\d{12}(?:\d{3})? | 5[1-5]\d{14} | +| IP_ADDRESS | IPv4 + v6 | `(?:\b\d{1,3}(?:.\d{1,3}){3}\b | (?:[A-Fa-f0-9]{1,4}:){7}[A-Fa-f0-9]{1,4})` | +| DOB | Dates like MM/DD/YYYY or YYYY-MM-DD | `\b(?:\d{1,2}[/-]\d{1,2}[/-]\d{2,4} | \d{4}-\d{2}-\d{2})\b` | +| ZIP | US ZIP / ZIP+4 | \b\d{5}(?:-\d{4})?\b | Locale-specific; extend with postcodes later. | + +

All patterns compiled with re.IGNORECASE | re.MULTILINE and wrapped in r'' raw strings.

+
+

2. Return-value schema

+

2.1 Keep the dict-of-lists for backward compatibility

+
from typing import Dict, List
+
+Annotation = Dict[str, List[str]]
+
+# e.g. {"EMAIL": ["[email protected]"], "PHONE": ["555-555-5555"]}
+
+
+ +

2.2 Offer an optional structured model (new but additive)

+
from pydantic import BaseModel
+from typing import List
+
+class Span(BaseModel):
+label: str # "EMAIL"
+start: int # char offset
+end: int # char offset
+text: str
+
+class AnnotationResult(BaseModel):
+text: str
+spans: List[Span]
+
+ +

Why both? Existing users don’t break; new users get richer data. The regex annotator returns both:

+
regex_result = {lbl: [s.text for s in spans_by_label[lbl]] for lbl in spans_by_label}
+return regex_result, AnnotationResult(text=input_text, spans=all_spans)
+
+

TextService will pick whichever format the caller asked for.

+
+

3. Performance budget

4. Edge-case policy
