Separate declared package requirements from environments SDAI has actually exercised.

Declared requirements for 0.4.1

olca-ipc	2.6.0+
olca-schema	2.6.0+
NumPy	1.24+
openLCA Desktop	2.x with IPC Server enabled

Verified SDAI snapshot

A recorded SDAI integration snapshot used openLCA Desktop 2.5.0 with the desktop IPC server on port 8080 and openLCA IPC 0.4.1, confirming a live database connection and entity-count smoke path.

Note

This evidence applies to that tested snapshot. It does not prove every openLCA 2.x/database/plugin combination.

Protocol compatibility is not study compatibility

Database licensing and redistribution rights.
Foreground completeness and provider links.
Flow properties and units.
Allocation/cutoff rules.
LCIA method suitability.
Normalization/weighting availability.

Upgrade checklist

Use a controlled test database.
Run connection and search smoke checks.
Rerun a known/reference calculation.
Verify non-mass unit handling where relevant.
Check contribution/result consistency.
Rerun scenario/uncertainty paths you depend on.
Record the environment and source revision.
Update claims only after evidence exists.
