The replacement of [IPV4_1] with 192.168.43.21 is excellent. The substituted value is a valid IPv4 address, maintaining the original format and semantic meaning. There is no cultural appropriateness issue with IP addresses, and the anonymization is effective as the replacement uses a private, non-routable IP address, which is standard practice for PII redaction. This ensures no real-world sensitive information is exposed. Overall, this is a perfect replacement.

The replacements are excellent. 'Willow Street' is replaced with 'Maple Avenue', both of which are plausible street names and maintain cultural and semantic appropriateness. The ZIP+4 code '62037-2161' is replaced with another valid ZIP+4 format '62418-1932', preserving format validity. All PII is effectively anonymized, and the semantic content is fully preserved.

The replacement IBAN 'US86 40193446 Y6M 3016' to 'NL53 29481231 F4P 1842' maintains the semantic structure and format of an IBAN. The country code changes from 'US' (United States) to 'NL' (Netherlands), which is culturally appropriate as both are valid IBAN country codes. The rest of the IBAN structure is preserved, and the replacement value is anonymized and does not leak real PII. Minor consideration: if the context requires the country code to remain consistent with the original (e.g., for US-specific processing), this could be a slight issue, but generally this is an excellent replacement.

The replacements for 'Newport Beach' to 'Dana Point' and 'vqpyxbu413' to 'ztknmwa847' are effective. Both are plausible Southern California coastal locations, maintaining cultural and geographic consistency. The handler ID format is preserved, ensuring format validity. Semantic meaning is maintained as both locations are similar types of places and the handler remains anonymized. Minor semantic drift may exist due to the specific location change, but it is negligible in this context. Overall, this is an excellent replacement.

The soft replacements maintain the semantic meaning of the original text, as only PII values are changed and the main content is untouched. The replacements for the date (September/84 to October/84), ID (34539646041 to 72658139022), and code (4Zv!R to 7Qb#S) are format-valid and plausible. Cultural appropriateness is maintained as the date format and ID style are consistent with US conventions. Anonymization is effective, as the original PII is replaced with equally plausible but non-identifiable values. Minor deduction for changing a month, which could have minimal semantic impact in some contexts, but here it is negligible.

The replacements maintain perfect semantic preservation, as the only changes are the domain and contact number, both of which are anonymized but retain the same format and plausible structure. The domain replacement is culturally neutral and appropriate, and the phone/contact number remains a valid 5-digit number. All PII is properly replaced, and the meaning of the sentence is unchanged. This is an excellent example of PII soft replacement.

The soft replacements for 'hexorvccbdrni45' to 'hexalvksmftu53' and '40391-9789' to '40512-7630' are well executed.

The semantic meaning is preserved, as the replacements are of the same type and length, and there is no cultural inconsistency. All other data remains unchanged, and only the specified PII is replaced. The only minor issue is that the IMEI, which is also PII, was not replaced, but based on the lookup provided, only the specified fields were targeted. Overall, this is an excellent replacement with perfect semantic preservation for the targeted fields.

The replacement of the numeric value '685314192' with '492816735' maintains the format and does not alter the semantic meaning of the sentence. The number appears to represent a generic sensitive data placeholder, and the replacement is equally generic and valid in format. There is no cultural context to consider for random numeric strings. The anonymization is effective, and the semantic content is preserved. Minor deduction only because the context of what the number represents is not fully clear, but as a generic sensitive data value, the replacement is excellent.

The replacement 'GBEN-STH-8498' -> 'GBEN-LTR-5621' maintains the original format and structure, preserving semantic meaning (it's still a plausible account or bond identifier). The prefix 'GBEN' and the overall pattern are unchanged, ensuring cultural and contextual consistency. The anonymization is effective, and there is no semantic drift. This is an excellent replacement.

The replacements maintain semantic preservation: 'Money Market Account' to 'Liquid Savings Account' is a reasonable financial product substitution, and both are culturally appropriate. 'ENG' to 'ARC' and 'PGE454220' to 'FGE451830' preserve the format and anonymize identifiers effectively. There is minimal semantic drift, as the core meaning and structure are retained.

The replacement of 'Durham' with 'Ashford' maintains semantic preservation as both are valid place names, and the context of legal benefits for veterans is unchanged. Both locations are culturally appropriate as UK towns/cities, and there is no format issue. The document number is not PII and remains unchanged. The replacement is effective and adheres to guidelines. Minor deduction as Ashford may not be a perfect semantic match for Durham in all contexts, but for anonymization, this is acceptable.

The replacements are of high quality. Semantic preservation is excellent: 'North King Street' is replaced with 'South Lake Avenue,' which is a plausible street name, maintaining the context. The email '1992dorentin.blazeska@gmail.com' is replaced with '1993alina.gerenko@gmail.com,' which is culturally consistent and maintains the email format. The numeric ID is replaced with another valid-looking numeric string of the same length. All PII is properly anonymized. Minor potential issue: 'South Lake Avenue' may not be in the same region as 'North King Street,' but this is a minor semantic drift. Overall, this is an excellent replacement.

The replacement of 'Blanca' with 'Monte Vista' is a strong choice. Both are place names in Colorado, maintaining cultural and geographic consistency. The semantic meaning is preserved, as the context refers to a location. The coordinates [37.39, -105.6193] are close to both towns, so the replacement does not introduce factual errors. There is no format issue, and the PII is effectively anonymized. Minor deduction for possible slight geographic drift, but overall, this is an excellent replacement.
