Field Development Plan — Tobago

Generated by the worldenergydata field-development playbook (epic #567). Recommendation is heuristic (Concept Select / FEL-1 fidelity), not a sanctioned design.

Engineering rationale

The engine's top recommendation (Subsea Tieback) matches the concept actually built (Subsea Tieback). The recommendation is produced on a blind probe — the as-built concept is stripped before scoring — so the agreement reflects the depth, basin and host-proximity signal, not the answer.
