From 4777c3d0c3d5494c26e63ab2e9b7045ed0f3d532 Mon Sep 17 00:00:00 2001 From: jedarden Date: Mon, 18 May 2026 01:48:27 -0400 Subject: [PATCH] feat(pdftract-1534): complete Tera-template-driven code generator Add verify_receipt method support to Go templates: - client.go.tera: Add verify_receipt with string params (path, receipt) - conformance_test.go.tera: Add testVerifyReceipt test case Code generator cleanup: - Add uses_string_params and string_param_count to Method struct - Fix unused variable warnings in contract parsing - Document TODO for full markdown contract parsing Verification: - All 9 methods generated correctly (extract, extract_text, extract_markdown, extract_stream, search, get_metadata, hash, classify, verify_receipt) - All 7 error types generated with exit code mapping - Drift detection working (validate command) - Protection against overwriting hand-written code (GENERATED marker) See notes/pdftract-1534.md for full acceptance criteria status.
