• Type: spark (subtype: conversion)
• event_id: 2026-05-03-food-security-cascade-conversion
• Source: Production perspective — 2026-05-01-food-security-cascade
• Shift: Perspective converted to research/ directory + log format on 2026-05-03 as part of perspective backfill. Parent linkage to us-energy-dominance preserved. Sibling linkage to gulf-infrastructure-strike preserved (Ras Laffan disruption amplifies nat gas supply risk).
• Effect on thesis: None substantively. Operational change.
• Per-ticker (initial reads): Carry forward from 2026-05-01 refresh.

Pre-conversion frozen state (informational, not log entries)

• 2026-02 — Iran war energy shock; Stage 1 spiked (USO $138, nat gas elevated)
• 2026-03 to 2026-04 — Stage 2 transmission through CF/NTR producers
• 2026-04-12 — Stage-2 fertilizer cascade observation: CF +51% 3M validated transmission
• 2026-04-26 — Retrospective marked HIT, evolving as predicted; SUSTAIN action
• 2026-05-01 — Friday EOW captured Stage 3 commodity-leg arrival + Stage 4 (MOS) still locked (production frozen at this state)

If we mass-backfill earlier shifts (deferred per master brief Stage 5), each prior refresh gets its own event entry.
