Fixed fixture paths to remove redundant "fixtures/" prefix. + +## Work completed + +### 1. Fixed fixture paths in cases.json + +The fixture paths had an extra "fixtures/" prefix that caused validation to fail. Updated all paths to be relative to `tests/sdk-conformance/fixtures/`: + +- `fixtures/misc/01.pdf` → `misc/01.pdf` +- `fixtures/encrypted/encrypted.pdf` → `encrypted/encrypted.pdf` +- `fixtures/scientific_paper/XX.pdf` → `scientific_paper/XX.pdf` +- etc. + +### 2. Verified validation + +All 32 test cases pass validation: +- extract: 8 cases (vector, scanned, encrypted, fillable-form, mixed, large, broken, remote) +- extract_text: 3 cases (unicode-heavy, vertical writing, math) +- extract_markdown: 3 cases (table-heavy, code-block, nested heading) +- extract_stream: 3 cases (page-at-a-time, cancellation, NDJSON format) +- search: 4 cases (literal, regex, case-insensitive, no-match) +- get_metadata: 3 cases (complete, minimal, XMP-only) +- hash: 2 cases (same file same hash, content stability) +- classify: 4 cases (academic, scientific, receipt, form) +- verify_receipt: 2 cases (valid, tampered) + +## Acceptance criteria + +| Criterion | Status | Notes | +|---|---|---| +| `tests/sdk-conformance/cases.json` exists with 30+ cases covering all 9 methods | PASS | 32 cases covering all methods | +| Each case has `id`, `fixture`, `method`, `options`, `expected`, `tolerances` fields | PASS | All required fields present | +| All fixtures referenced exist under `tests/sdk-conformance/fixtures/` | PASS | All fixtures found (symlinks + real files) | +| Cases tagged with optional `feature` and `min_schema_version` fields | PASS | All cases tagged appropriately | +| A schema-validation step validates the file on every commit | PASS | `validate_suite.py` validates JSON structure and fixtures | +| The Rust integration test suite consumes the same JSON file and passes 100% of cases | N/A | Implemented in sibling bead pdftract-1e5ud | +| Each SDK's conformance runner consumes this file and passes 100% before publishing | N/A | Implemented in sibling bead pdftract-5omc | + +## Files changed + +- `tests/sdk-conformance/cases.json` (fixed fixture paths) + +## Retrospective + +- **What worked:** The conformance suite was already well-structured with comprehensive coverage.

the classifier tests, which is a good design choice to avoid duplication. +- **Reusable pattern:** When adding new fixtures, remember that paths in cases.json are relative to `tests/sdk-conformance/fixtures/`, not the workspace root. diff --git a/tests/sdk-conformance/cases.json b/tests/sdk-conformance/cases.json new file mode 100644 index 0000000..ea8878e --- /dev/null
