[11.0][A3] Remove deprecated IDataEngine interface (use IDataDriver) #2378
Description
Activity
Scope correction (implemented in #2384). On inspection,
IDataEngineis not deprecated — it's the live engine-layer contract (ObjectQL implements IDataEngine, 60 refs). The genuine@deprecatedalias isDriverInterface(= IDataDriver). #2384 removesDriverInterface(spec/contracts + core re-export), migratesobjectql/engine.tstoIDataDriver(type-identical), and regenerates api-surface.IDataEnginestays; the separate zodDriverInterface/DriverInterfaceSchemain spec/data also stays. Verified: spec 32 + objectql 718 green.- added a commit that references this issue
on Jun 27, 2026 Re-evaluation — no code work remains; closing as completed.
The issue title rests on a wrong premise. On inspection,
IDataEngineis not deprecated — it's the live engine-layer contract (ObjectQL implements IDataEngine; ~281 typed references across the tree today, no@deprecatedannotation). The genuine deprecated alias wasDriverInterface(= IDataDriver).That scope-corrected removal already landed in #2384 (merged, 11.0):
DriverInterfacedropped fromspec/contracts+ the@objectstack/corere-export,objectql/engine.tsmigrated toIDataDriver(type-identical), api-surface regenerated, anddocs/upgrading-to-11.mdcarries the migration note. The only remainingDriverInterfaceonmainis the separate zodDriverInterfaceSchemainspec/data(same name, different thing — the runtime driver schema — deliberately kept).So there is nothing left to do here:
IDataEngineshould stay (it's the live engine contract; removing/renaming it would be a large breaking change with no benefit, and is a different architectural layer from the driver contract). Closing.
