| All 10 sub-phase beads (7.1-7.10) closed | ✅ PASS |
|
||
| Tagged PDF reading order matches StructTree | ✅ PASS (7.1) |
|
||
| Table extraction handles bordered + borderless + merged cells | ✅ PASS (7.2) |
|
||
| AcroForm tx/btn/ch + XFA extract correctly | ✅ PASS (7.4) |
|
||
| pdftract grep 50 MB/s throughput | ⚠️ WARN (7.8 - CI-gated, fixture corpus pending) |
