Field Development Plan — St. Malo

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 (Tlp) differs from the concept actually built (Semisub Fps). The recommendation is produced on a blind probe (the as-built concept stripped before scoring); the shortlist below shows where the built concept ranks. Divergence is expected where the real choice turned on data outside the engine's inputs (reserves, schedule, operator preference).
