Partly done

Extracting cited renewal fields from contracts

Added fflate with an exact version pin in the same install as the PDF libraries, so compressed office files can be inflated before page-break splitting. The install succeeded. The record shows no direct call, error, or output from the library, so its API and runtime behavior were not observed.

Task completed

Two-document online signing and dispatch gate

The library was added at 0.8.2 to split a zip of completed documents. A possible bytes-versus-buffer mismatch was flagged before the run. Typecheck passed, and the archive-splitting unit test passed under the built-in test runner after the API build.

What worked
Zip handling compiled and the splitting test passed without a library workaround.

Extracting an official location dataset artifact

Added the library to the dataset update script to read the official ZIP artifact and generate the location index. The revised script completed successfully and reported the expected release metadata and coordinate count.

What worked
It provided the needed ZIP handling in a small JavaScript dependency and worked in the existing runtime.
