Examples
Current deployment directory URL: https://old.example.invalid/
Destination deployment directory URL: https://new.example.invalid/site/
File/directory path map (JSON): {}
Limitations
- Apply a simultaneous longest explicit file/directory-prefix map to a complete static-site ZIP. Map keys/values are safe archive paths;directories end in slash. All recognized URLs under the old deployment root become absolute destination URLs;directory indexes become actual mapped index.html filenames. Queries/fragments and unrelated member payloads stay intact. Refuse collisions,invalid/credentialed/ambiguous URLs,unparsed CSS/compound/context features and changed inline CSS under CSP meta. Existing valid local non-HTML SHA256/384/512 integrity tokens are verified then recomputed for changed asset bytes. Missing references remain explicit findings,no files are invented. Output is inspected with the same resolver. Source scripts/active content,external origins,unparsed assets,server routing and hosting/CSP behavior remain outside compatibility claims. ZIP64MiB/report20MiB/80MiB combined;rewritten text obeys the same input profile. One ordinary stored/Deflate ZIP up to20 MiB,1,000members/16MiB per member/64MiB expanded.

HTML parsing uses native-compatible inert parse5 with100levels/100,000nodes per document. No script,HTML,CSS,resource or server is executed/fetched;all processing stays in your browser.
- Complete outputs only. Unsupported or oversized input is refused. Follow the displayed job-specific bounds and format policies.
