Description
Promoted from #1982 P1 to a standalone tracked issue (was previously only a roadmap bullet).
Problem
tload/tstore exist in the EDSL + Core and the synthesized nonreentrant guard (#1893), but general transient storage for arbitrary computed slots is still expressed via raw per-slot ECMs downstream. Morpho Midnight's liquidation lock requires raw transient-slot ECMs at Midnight/Contract.lean:1109–1274 (Th0rgal/morpho-verity).
Goal
- Source-level transient variables/mappings (computed slots included) with the same typing discipline as persistent storage.
- Interpreter semantics + proof support (transaction-scoped reset), enabling the deferred
nonreentrantguard proof to land. - Kill the
midnight_liquidation_lock_transient_*ECM cluster.
Acceptance
Midnight's liquidation lock expressible as ordinary source; trust report shows no transient-slot ECMs.

Research direction
Start by reading the existing tload/tstore support in the EDSL and Core, then inspect the raw transient-slot ECMs in Midnight/Contract.lean:1109–1274. The work is done when Midnight's liquidation lock uses ordinary source-level transient storage and the trust report contains no transient-slot ECMs.
