TMF ↔ GR/QM: Deductive Upgrade — Closing Gap A and Gap B (Working Document v0.4)

Second document in the TMF ↔ GR/QM Correspondence Programme series, following v0.2. Two previously phenomenological identifications — the projection norm ‖π_*(E_L)‖ (Gap A) and the TMF evanescent decay coefficient κ_TMF (Gap B) — are now derived as conditional deductions from TMF postulates P1–P5. Both carry status [PARTIAL DEDUCTION]: the logical chain follows necessarily from the stated postulates, but those postulates themselves await independent axiomatic grounding. The exponential transmission probability T_TMF ≈ exp(−2∫κ_TMF dx) is preserved. Continues: TMF ↔ GR/QM Correspondence Map v0.2.
