- Step 3.5: fetch signerEmail from tokenRow after atomic claim - Step 7: accumulate pattern — read from signedFilePath or preparedFilePath as working PDF - Step 7: write to JTI-keyed _partial_ path to prevent concurrent signer collisions - Step 8a: date stamps scoped to this signer's date fields (D-09) - Step 8b: signable fields scoped to this signer's fields (Pitfall 4) - Step 9.5: JTI-keyed datestamped temp file to prevent collision - Step 10.5: update signedFilePath to this signer's partial after each signing - Step 11: remaining-token count check before completion attempt - Step 11: completionTriggeredAt atomic guard (UPDATE WHERE IS NULL RETURNING) - Step 12: status='Signed' only in completion winner block (fixes first-signer-wins bug) - Step 13: agent notification + signer completion emails only at completion - Legacy null-signerEmail tokens fall through all signer filters unchanged
