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.
