Summary

Implements every operation that the official Veryfi API documentation currently exposes and updates the audit to 100% coverage.

• 151 documented operations revalidated from their live docs pages
• 103 formerly missing operations added
• 24 partial operations completed
• 151 IMPLEMENTED / 0 PARTIAL / 0 MISSING / 0 UNCERTAIN
• Existing public APIs remain source-compatible

Implementation

Correctness fixes

• Encode GET parameters on the query string (RFC 3986) instead of JSON request bodies
• Correct multipart handling and allow cURL to set multipart boundaries
• Fix local-file uploads for W-2 and W-9
• Preserve the AnyDocs $template_name argument while sending documented blueprint_name
• Expand line-item request models for detailed-field objects and current fields

Added resource coverage

• Existing resources: update, tags, async, bulk documents, tax lines, remittance checks, W-2/bank statement sets
• Contracts
• Parse/Markdown and document sets
• Classify-and-extract
• Fraud device blocklist
• Settings: webhooks, client keys, v1 API keys, TLS certificates
• Blueprints, OCR counts, OpenAPI schema, release notifications

All methods reuse veryfi\Client, the existing trait architecture, cURL request layer, authentication/signature logic, raw JSON string responses, and snake_case naming.

Documentation

• docs/api-coverage-analysis.md: complete 151-row mapping and 100% metrics
• README.md: pagination, async, Contracts, Markdown, tags/updates, and settings examples
• PHPDoc URLs on every new operation

Validation

• ./vendor/bin/phpunit --no-coverage: 179 tests, 676 assertions, passing
• API parity suite: one contract test for every one of the 103 new operations
• Parameter regressions: GET query encoding, AnyDocs blueprint, multipart W-2/W-9/classify/split, line-item schema
• PHP syntax: 100 source/test files valid
• Coverage report invariant: 151/151 IMPLEMENTED
• composer.json JSON and PSR-4 mapping validated
• git diff --check: passing

The Cloud image does not include the composer executable, so composer validate --strict could not be run locally; CI retains that validation step.
