Motivation

• Repair and complete the v1.1.0 commercial example suite so the set is clean, protocol-grade, and safe to merge.
• Ensure each invalid example isolates a single schema failure and each verb has broadened valid coverage demonstrating allowed alternative states.

Description

• Fixed malformed / ambiguous examples and tightened payloads across authorize, checkout, purchase, ship, and verify so every changed JSON file is syntactically valid and uses canonical v1.1.0 vocabulary.
• Added one materially different valid receipt per verb to broaden coverage (denied/pending/in-transit/inconclusive states) and created corresponding files under examples/v1.1.0/commercial/*/valid/901-*.json.
• Revised invalid examples so each now fails for exactly one intended reason (e.g., wrong money type, empty items, zero quantity, unsupported commercial_ref.type, missing conditional payment_proof/approved_until/delivery_proof_ref/reason).
• Regenerated checksums.txt to include the expanded example inventory and committed all changed example files and checksums.

Testing

• Ran duplicate-key JSON sanity check with Python: json.load(..., object_pairs_hook=no_dups) against examples/v1.1.0/commercial and it completed without errors.
• Ran example validation: npm run validate:examples and full validation: npm run validate which both completed successfully and reported all current-line examples validated.
• Regenerated checksums with npm run generate:checksums and validated integrity via npm run validate where integrity validation passed after the update.
• Confirmed that all modified valid examples pass and all invalid examples fail for their single intended schema reason when validated with AJV.
