Certified Bridge Registry (8 Bridges)
| ID | Bridge | Strength | Assessment |
|---|---|---|---|
| B-01 | LCI debt → Morga debt-bondage | Strong | 5-source, 709-year continuity; strongest bridge |
| B-02 | Butuan → Chinese trade network | Moderate | Song records + Morga + archaeology |
| B-03 | Ma-i → Tondo continuity | Moderate | Geographic overlap; no direct succession evidence |
| B-04 | Islamization → Moro resistance | Strong | Unbroken chain, well-documented |
| B-05 | Barangay → colonial admin unit | Strong | Morga + Felipe II law 1594 |
| B-06 | Indigenous maritime → galleon corvée | Strong | Suppression thesis; 4-phase documentation |
| B-07 | Hindu substrate → LCI | Weak | Temporal gap; indirect evidence only |
| B-08 | Confederation → Islamization | Weak | Single-source (Rizal note 314) |
Certified Fork Disposition (13 Forks)
RESOLVED (3):
- FK-06: Dual-script coexistence (baybayin + Jawi)
- FK-09: Regional redistribution model (not uniform depopulation/growth)
- FK-10: Paradigmatic gap (fort artillery ≠ personal firearms tradition)
NARROWED (4):
- FK-01: LCI as system evidence (strengthened by Morga; gap remains)
- FK-03: Ma-i location (Manila Bay area favored; Mindoro not eliminated)
- FK-08: 12th-century documents (unidentified; Rizal claim noted but unverified)
- FK-11: Class system facilitated conquest (partially true for initial phase; overridden by later resistance)
OPEN (6):
- FK-02: Butuan’s post-11th-century fate (no new evidence)
- FK-04: Tondo political structure (insufficient data)
- FK-05: Islamization depth (gradient model holds; no resolution)
- FK-07: “Functions bridge, forms do not” (confirmed for debt-law; challenged for food systems)
- FK-12: Sanskrit in-situ vs. pre-migration (false binary; continuous process)
- FK-13: Food scarcity paradox (resolved as colonial creation; but pre-colonial surplus scale unknown)
The Historian’s Story 05 Certification
The main-probable branch is CERTIFIED for Story 05 publication with the following caveats:
- Layer 0 (ghost period) should be presented as inferred, not documented
- TL-016 (confederation) should carry an explicit “Rizal’s assertion, unverified” flag
- TL-019 (copper Buddhas) should carry an explicit “unrecovered” flag
- B-07 and B-08 should be presented as hypothetical
- All 6 open forks should be presented as open research questions
The timeline represents the best available synthesis of all evidence through Cycle 20. It will never be “complete” — the 500-year gap between TL-001 (900 CE) and TL-004 (pre-1300 Tondo) remains the most significant lacuna. But the synthesis is honest about its gaps, explicit about its confidence levels, and traceable to primary sources.
