The V3 pipeline has been tested against the full 555-paper vault vs legacy:
No diff: 547 (98.6%)
Diff: 5 (0.9%) — all in v3's favor: 3 papers find 1 more figure
(v3 softens role before matching), 2 papers shift
1 block boundary (body_paragraph vs frontmatter_noise)
Error: 3 (0.5%) — 2 missing raw data, 1 pre-existing v3 pipeline edge case
The 5 diffs are marginal improvements, not regressions. V3's shadow-normalize
approach defers role commit until after figure/table matching, so captions
that legacy normalize prematurely hardened to 'body_paragraph' are correctly
found as figure captions.
Changes:
- _ocr_pipeline_v3_enabled() defaults to True now; set OCR_PIPELINE_V3=0 to
revert to legacy normalize-then-match order
- Test updated to assert default=True
- Full vault corpus diff script + result report archived
- add fixture-backed replay parity for 37LK5T97, 8CCATQE3, and 5MAW65YD
- keep existing DWQQK2YB, VAMSAZMG, and PJBMGVTF gates
- update OCR project status and queue to 105-test state
- add fixture-backed parity replay for VAMSAZMG and PJBMGVTF
- keep DWQQK2YB as existing replay gate
- sync post_match render/index defaults to legacy contract
- update OCR status docs to 102-test state
- sync render/index defaults in post_match_normalize to match legacy
- add fixture-backed real-paper parity test for DWQQK2YB
- update OCR project status and active queue to 100-test state
- Rewrite pre_match_normalize to run a shadow normalize pass that
populates role_candidate on each block while preserving public role
- Add _match_role(block) helper to ocr_figures.py (role_candidate > role > seed_role)
- Port matching-time role reads in figure builders to use _match_role
- Add _match_role(block) helper to ocr_tables.py (same priority)
- Port matching-time role reads in table builders to use _match_role
- Port role reads in FigureCorpus.from_blocks and TableCorpus.from_blocks
- Add 3 C1 tests to test_ocr_pipeline_v3.py
- All 325 OCR tests pass (6 C0+C1 + 4 rendering + 5 writeback + 310 figures)
