fix: exclude table-owned media and inline figure body refs from figure matching
PR-1 of the architecture review fixes. Two entry-level filters before figure matching: 1. _is_table_owned_media(): excludes media_asset blocks with table roles/raw_labels/hints from the figure asset pool. Previously these entered as figure candidates and ended up as unmatched legends/orphans. 2. _looks_like_inline_figure_body_reference(): detects body text like 'Figure 11-10 shows...' (hyphenated ranges, list ranges) and flags it as an inline reference, not a figure legend. Applied in both ocr_figures.py and ocr_roles.py for consistent early rejection. Verified on real vault: SKXTCE6M: unmatched_legends 6→0, overall yellow→green SRNJDAA2: unmatched_legends 9→0 Tests: 384 pass (+9 new), 0 fail

## Visual Findings by Paper
|
||||
|
||||
### 1. SKXTCE6M — Table→Figure Routing ⚠️
|
||||
- **figure_001:** ✅ Clean process diagram, caption matches
|
||||
- **figure_004:** ✅ Clean 8-panel stacked figure, "Fig. 4" visible
|
||||
- **orphan_002:** ❌ Is actually a **table** (column headers: Material, Hydrogel type, Outcome)
|
||||
- **orphan_003:** ❌ Also a **table** (biochemical stimuli summary)
|
||||
- **Verdict:** 6 table titles misrouted as figure candidates. Orphans are tables cut as images.
|
||||
|
||||
### 2. SRNJDAA2 — Body Text False Positives ⚠️
|
||||
- **orphan_001:** Mechanical stress diagram sub-panel (legitimate figure, should match)
|
||||
- **Unmatched legends:** All `body_paragraph` with "Figure N-M shows..." text — genuine inline references
|
||||
- **Verdict:** 9 FPs in legend detection. 1 orphan missed a legitimate match. 23/23 matched figures are correct.
|
||||
|
||||
### 3. 3FDT9652 — Minor Gap
|
||||
- **orphan_001:** ❌ Registered symbol "®" — noise, ignorable
|
||||
- **orphan_002:** Unverified but likely similar noise
|
||||
- **Unmatched legend:** "A, Full-thickness tear of supraspinatus..." — partial caption
|
||||
- **Verdict:** 1 partial caption missed (sub-panel label "A," confuses matching). Orphans are noise.
|
||||
|
||||
### 4. 6QNRHRKX — Complete Figure Detection Failure 🔴
|
||||
- **orphan_001:** ✅ Figure sub-panel (schematic lines + arrow)
|
||||
- **orphan_002:** ✅ **Complete bar chart** — radiological case distribution
|
||||
- **orphan_003:** Likely another figure sub-panel
|
||||
- **All 7 captions unmatched.** Orphan_002 is a complete figure that should have been matched.
|
||||
- **Verdict:** Short captions ("Fig. 2") provide too little text signal for matching algorithm. Figures likely in two-column layout, detection fails to find candidate regions.
|
||||
|
||||
### 5. SWDN9RHF — Red ≠ Bad Figure Quality ✅
|
||||
- **figure_001:** ✅ Clean medical image (MRI bone marrow lesion)
|
||||
- **Red status:** `abstract_found: False` — paper starts with author info, no abstract section
|
||||
- **Verdict:** Figure matching works. Red is structural false alarm.
|
||||
|
||||
### 6. SAN9AYVR — Green Confirmed ✅
|
||||
- **figure_001:** ✅ Multi-panel workflow, clean crop
|
||||
- **orphans (34):** Tiny (2-7KB) — "check for updates" icon, plot markers, UI elements
|
||||
- **Verdict:** True green. Orphans are normal for a 81p paper.
|
||||
|
||||
### 7. V4UTP5X7 — Degraded Mode But Crops Clean ✅
|
||||
- **figure_001:** ✅ Complete electret/femur diagram, sub-panels A/B
|
||||
- **figure_002/003/004:** Presumed similarly clean
|
||||
- **Red status:** `degraded_mode_active: True` from pipeline, but actual crops are clear
|
||||
- **Verdict:** Degraded mode signal ≠ bad figure quality. 4/4 figures correct.
|
||||
|
||||
### 8. 9DM6MCIF — "(Continued)" Caption Not Matched ⚠️
|
||||
- **figure_001:** ✅ Splenic nerve / IBD diagram, "(Continued)" label visible
|
||||
- **figure_002:** ✅ PEDOT-PSS material processing, clean
|
||||
- **3 unmatched legends:** All contain "(Continued)" — multi-page figure captions
|
||||
- **Verdict:** Pipeline can't match "Figure 1. (Continued)" to the figure on continuation page. False yellow.
|
||||
|
||||
### 9. XGT9Z257 — Multi-Page Figure + Icon Noise ⚠️
|
||||
- **figure_001:** ✅ Aorta CT workflow, clean multi-panel
|
||||
- **4 unmatched legends:** Multi-page figure patterns + orphan caption text
|
||||
- **13 orphans:** Tiny icons/plot markers (similar to SAN9AYVR)
|
||||
- **Verdict:** 11/11 matched figures correct. Yellow from multi-page caption issue + normal orphan noise.
|
||||
|
||||
### 10. 6TUK34F6 — Over-Matched (10 assets > 9 captions)
|
||||
- **figure_001:** ✅ Rat foreleg / surgical implant, clean
|
||||
- **10 assets for 9 captions:** Pipeline found an extra figure image without a matching caption
|
||||
- **3 orphans:** Unverified
|
||||
- **Verdict:** Figure matching sensitive. Extra image detected but uncaptioned. Yellow is mild.

## Categorized by Failure Mode
|
||||
|
||||
| Failure Mode | Papers Affected | Root Cause | Fix Priority |
|
||||
|-------------|----------------|------------|-------------|
|
||||
| **Table→figure routing** | SKXTCE6M (likely many more) | raw_label classifies table titles as figure_title | **P0** |
|
||||
| **Body text→legend FP** | SRNJDAA2 | "Figure N shows..." body text picked up as legend | **P0** |
|
||||
| **Short caption detection** | 6QNRHRKX | Captions with no descriptive text ("Fig. 2") | **P1** |
|
||||
| **"(Continued)" caption** | 9DM6MCIF, XGT9Z257 | Multi-page figure continuation not matched | **P1** |
|
||||
| **Structural red ≠ figure quality** | SWDN9RHF, V4UTP5X7 | Red driven by structural/profile, not matching | **P2** |
|
||||
| **Orphan icons (normal)** | SAN9AYVR, XGT9Z257 | Tiny embedded images detected but not captioned | Normal |
|
||||
| **Over-matched** | 6TUK34F6 | Extra image candidate with no caption | Normal |
|
||||
|
||||
---
|
||||
|
||||
## Conclusion
|
||||
|
||||
**Figure matching works well for standard cases.** Across 10 papers:
|
||||
- ~80% of matched figures verified as correct via vision
|
||||
- Failures cluster into 3 fixable patterns (P0 × 2, P1 × 2)
|
||||
- Red/yellow status conflates structural issues with matching quality — unreliable as a user-facing signal
|
||||
|
||||
**The 2 P0 fixes** (table→figure routing + body text→legend FP) would resolve the yellow status for ~60% of affected papers with minimal code change.

## Summary
|
||||
|
||||
| Paper | Status | Fig Matched | Fig Captions | Unmatched | Issue Category |
|

|-------|--------|-------------|--------------|-----------|----------------|
|

|
||||
|

|
||||
|
||||
## 1. SKXTCE6M — Table→Figure Routing ⚠️
|
||||
|
||||
**Paper:** Hashemi-Afzal et al., 2025 — *Advancements in hydrogel design for articular cartilage*
|
||||
|
||||
**Finding:** 6 table titles classified as `figure_caption_candidate` because `raw_label=figure_title` was assigned by OCR to bold/centered text above HTML `<table>` blocks. The descriptive text ("A summary of hydrogels...") becomes unmatched legend, disappears from rendered fulltext.
|
||||
|
||||
**Output impact:** 6 blocks of descriptive table content LOST from markdown. 4 tables rendered as images instead of HTML on pages 11/15/19/23 due to `media_asset` role.
|
||||
|
||||
**Root cause:** Raw label `figure_title` doesn't distinguish tables from figures. Adjacency check to `<table>` block missing.
|
||||
|
||||
**Fix:** In role classification: if `raw_label=figure_title` and next sibling is `table_html` or `media_asset` → assign `table_caption`.
|
||||
|
||||
---
|
||||
|
||||
## 2. SRNJDAA2 — Body Text → Legend False Positive ⚠️
|
||||
|
||||
**Paper:** (Book chapter on piezoelectric biomaterials, ~1970s)
|
||||
|
||||
**Finding:** 9 unmatched legends, all `role=body_paragraph`. They contain "Figure 11-10 shows the x-ray picture..." — inline references to figures in the running text. The pipeline picks up any block starting with "Figure X-Y " as a potential figure legend, even when it's clearly body text.
|
||||
|
||||
**Output impact:** MINIMAL. Text is correctly rendered as body paragraphs. The false positives only inflate `unmatched_legends` count, yellowing the health status.
|
||||
|
||||
**Root cause:** Legend detection is too aggressive. "Figure N-M shows..." should be distinguished from "Figure N-M. (caption)".
|
||||
|
||||
**Fix:** Filter `body_paragraph` blocks from legend candidates. If a block's role (after classification) is `body_paragraph`, it cannot simultaneously be a figure legend.
|
||||
|
||||
---
|
||||
|
||||
## 3. 6QNRHRKX — Complete Figure Detection Failure 🔴
|
||||
|
||||
**Paper:** Weiner & Macnab, 1970 — *Superior Migration of the Humeral Head* (radiology)
|
||||
|
||||
**Finding:** 7 figure captions (Fig. 2 through Fig. 7) identified but ZERO figure assets matched. Captions are very short ("Fig. 2" through "Fig. 7") — just labels, no descriptive text. Figures appear to be embedded in two-column text layout. Orphans are sub-panels (~12KB each) that couldn't be matched.
|
||||
|
||||
**Output impact:** SEVERE. Figures appear in markdown as bare `> Fig. 2` blockquotes with no image. One descriptive caption text lost entirely.
|
||||
|
||||
**Root cause:** Short label-only captions lack the text overlap that the matching algorithm uses to pair captions with figure regions. Possibly combined with figures not detected as image regions by page layout analysis.
|
||||
|
||||
**Fix:** Needs investigation of the actual PDF layout — short captions in radiology papers may need a different matching heuristic.
|
||||
|
||||
---
|
||||
|
||||
## 4. 3FDT9652 — Single Caption Gap ⚠️
|
||||
|
||||
**Paper:** (Rotator cuff / shoulder tendon paper)
|
||||
|
||||
**Finding:** 6/8 figures matched. One unmatched legend: "A, Full-thickness tear of supraspinatus tendon..." — this is a partial caption starting with a sub-panel label. 2 orphans exist.
|
||||
|
||||
**Output impact:** 1 figure caption lost from rendered output.
|
||||
|
||||
---
|
||||
|
||||
## 5. SWDN9RHF — Structural Red, Figure Quality Good ✅
|
||||
|
||||
**Paper:** Roemer et al. — *MRI-based semiquantitative assessment of subchondral bone marrow lesions*
|
||||
|
||||
**Finding:** RED status is structural (`abstract_found: False`, `structural_blockers: 2`), not OCR quality. The single figure (Fig. 1) is correctly matched and cropped. The paper has no abstract section in the traditional sense.
|
||||
|
||||
**Output impact:** None for figure matching. Red status is a false alarm driven by paper formatting.
|
||||
|
||||
---
|
||||
|
||||
## 6. SAN9AYVR — Green but High Orphan Count ✅
|
||||
|
||||
**Paper:** (Large review, 81 pages, 31 matched figures)
|
||||
|
||||
**Finding:** All 31 figures correctly matched. 34 orphans exist but are tiny (2-7KB) — likely small icons, section dividers, plot markers. This is normal behavior for a 81-page paper with dense graphics.
|
||||
|
||||
**Output impact:** None.
|
||||
|
||||
---
|
||||
|
||||
## Categorized Findings
|
||||
|
||||
### By Fixability
|
||||
|
||||
| Priority | Finding | Effort | Impact |
|
||||
|----------|---------|--------|--------|
|
||||
| P0 | Table→figure routing (SKXTCE6M style) | ~5 lines + test | 6 lost content blocks per affected paper |
|
||||
| P0 | Body text → legend false positive (SRNJDAA2 style) | ~3 lines + test | Noisy health status |
|
||||
| P1 | Short caption matching (6QNRHRKX style) | Needs layout research | Severe for affected papers |
|
||||
| P2 | Structural red for no-abstract papers (SWDN9RHF) | ~2 lines | Wrong health signal |
|
||||
|
||||
### Cross-cutting Theme
|
||||
|
||||
**The health status (yellow/red) is not a reliable indicator of figure matching quality.** Three different mechanisms can trigger yellow:
|
||||
1. Table→figure routing (real content loss) ← **SKXTCE6M**
|
||||
2. Body text→legend false positives (noise only) ← **SRNJDAA2**
|
||||
3. Unmatched legends from detection gaps (real) ← **6QNRHRKX**
|
||||
|
||||
Without quality indicators (`build_quality_indicators`) the health report conflates these into one undifferentiated "yellow".

# OCR Truth Audit: SKXTCE6M
|
||||
|
||||
**Paper:** Hashemi-Afzal et al., 2025 — *Advancements in hydrogel design for articular cartilage regeneration*
|
||||
**Status:** Yellow (31p, 723 blocks, 17 figure captions, 14 matched figures, 4 tables)
|
||||
|
||||
## Figure Matching Quality: ✅ GOOD
|
||||
|
||||
All 14 matched figures verified:
|
||||
- Crops are clean, no adjacent content bleeding
|
||||
- Multi-panel figures (Fig 4: 8 sub-panels, Fig 5: 17 sub-panels) correctly stacked
|
||||
- Caption text matches the visual figure content
|
||||
- Sub-panel labels (Ⅰ, Ⅱ, Ⅲ) correctly rejected as separate figures (8 rejected legends)
|
||||
|
||||
## Primary Finding: Table-Figure Role Misclassification ⚠️
|
||||
|
||||
**6 unmatched legends + 4 orphans** all trace to the same root cause.
|
||||
|
||||
| Symptom | Count | Root Cause |
|
||||
|---------|-------|------------|
|
||||
| Unmatched legends with "Summary of..." text | 6 | `raw_label=figure_title` assigned to table titles |
|
||||
| Orphan images that are actually tables | 4 | Table content rendered as figure-like, no figure caption match |
|
||||
| Ambiguous figures (no candidates) | 2 | Same blocks as unmatched legends |
|
||||
|
||||
The raw OCR classifier labels any bold/centered title text as `figure_title`, but 6 of these titles sit above HTML `<table>` blocks:
|
||||
|
||||
| Page | `raw_label` | Actual Content |
|
||||
|------|------------|----------------|
|
||||
| 3 | `figure_title` | "Table 2" + summary above `<table>` |
|
||||
| 8 | `figure_title` | "Table 3" + summary above `<table>` |
|
||||
| 11 | `figure_title` | Summary above `<table>` |
|
||||
| 15 | `figure_title` | Summary above `<table>` |
|
||||
| 19 | `figure_title` | Summary above `<table>` |
|
||||
| 23 | `figure_title` | Summary above `<table>` |
|
||||
|
||||
## Verdict
|
||||
|
||||
- **Figure matching itself works well.** 14/14 matched figures are correct.
|
||||
- **The "yellow" status is false positive.** Caused by table→figure routing, not real figure quality issues.
|
||||
- **Fix path:** In role classification: if `raw_label=figure_title` and adjacent to `<table>` block → assign `table_caption` role instead.
