🟡 Email masking deletes trailing punctuation
When an email ends before a period, re.sub consumes that period. The anonymized sentence loses punctuation unrelated to the address.

Fixed at exact head 67433f375ea1b8eb38baf3bf512ac761d9325dbd. PR #1482 is now stacked on the canonical tool-owner chain and reuses _EMAIL_PATTERN; trailing sentence punctuation is preserved and covered by endpoint regression.

🔍 Masking scope overstates anonymization
The catalog presents three contact-pattern substitutions as broad personal-data anonymization. Repository guidance requires narrower claims for contact redaction.

Fixed at exact head 67433f375ea1b8eb38baf3bf512ac761d9325dbd. Catalog copy now names only the supported email, selected Korean/North American/French phone, and Korean resident-registration formats, and explicitly states that complete de-identification is not guaranteed.

🔍 Privacy feature lacks research grounding
The substantive privacy-processing feature adds no permissible paper, citation, link, or summary required by repository research guidance.

Fixed at exact head 67433f375ea1b8eb38baf3bf512ac761d9325dbd. docs/doctoring/data-anonymizer-boundary.md records the exact stack parent, synthetic regression scope, NIST SP 800-188 rationale, and APA 7th citation. The official linked PDF endpoint returned HTTP 404, so the DOI and bounded summary are recorded without an unverified binary.

🟥 Common personal-data formats remain exposed
Internationalized emails and common Korean number formats bypass re.sub. Successful responses still expose personal data users requested to anonymize.

When an internationalized address is immediately followed by same-script prose—a normal construction in Korean and Japanese—the final [^^\W_]{2,63}-style domain match consumes the prose as part of the TLD. For example, 사용자@예시.한국으로 보내세요 becomes ***@*** 보내세요, deleting 으로 from the anonymized text. Bound the Unicode domain using validated IDN/public-suffix handling rather than treating every following Unicode word character as part of the address, and add this case to the existing data-anonymizer endpoint tests.

When an internationalized domain is supplied in its valid ASCII IDNA form, the address is returned unchanged because the final label rejects hyphens. For example, user@xn--fsqu00a.xn--0zwm56d is not matched by either email pattern, even though the catalog advertises email-address masking and the boundary document specifically includes internationalized email. Accept and validate xn-- A-label TLDs, and add the ASCII IDNA equivalent of the existing Unicode-domain case to the endpoint regression test.

When a French number uses its standard international representation, such as +33 1 42 68 53 00 or +33142685300, it is returned unchanged because this branch only accepts the domestic leading 0. This leaks the same identifier that the tested 01 42 68 53 00 form masks, and international/E.164 formatting is common in contact data. Add a bounded +33 alternative that accounts for the omitted domestic prefix and cover both spaced and separator-free forms in the endpoint test.
Useful? React with 👍 / 👎.

AGENTS.mdownership repair propagated from #1302. Commitae9b8a9b...normally merges that parent and adopts its guidance without changing this child’s anonymizer source/tests/doctoring. No force push or destructive rebase was used.This child continues to provide bounded format-based masking for contacts and Korean resident-registration-number representations; it does not claim complete de-identification. Separator-free Korean mobile/RRN forms, the implemented internationalized-email/French-phone cases, punctuation preservation, and
ANALYSIS_TEXT_MAX_CHARSremain the owned contract. NIST SP 800-188 remains the evidence boundary between format substitution and risk-managed de-identification.Predecessor checks/local results do not transfer.
