Google ADK → Memanto Migration — 10/10 Verified

A new Path B migration showcase for Google ADK's JSON-backed SqliteSessionService:

The adapter is standard-library only. It maps current app/user/session state into typed OKF memories, preserves the exact normalized source snapshot, renders source sessions as readable context, and isolates superseded values outside memories/ so corrected facts cannot be reactivated during import. The artifact verifier fails closed on malformed metadata, duplicate entries, unlisted memory files, absolute paths, traversal paths, and snapshot/hash mismatches. Capture also aborts if the SQLite database changes during the read.

Metric Result Google ADK sessions 8 Persisted events 17 Durable state updates 13 Source state records 10 OKF / Memanto memories 10 Skipped 0 Superseded timelines archived 3 Types represented 9 Source golden recall 8/8 (100%) OKF-mapped golden recall 8/8 (100%) Live Moorcheh import 10/10, 0 failed Live Moorcheh recall 8/8 (100%) Live Memanto → OKF reexport 10/10 memories

The OKF importer does not expose --report, and ADK SQLite stores no token, latency, or billing baseline, so the report deliberately claims no synthetic provider savings.

The focused adapter suite passes 32/32 tests. The full repository suite is green (612 collected; 586 passed and 26 expected platform/live-key skips on Windows). The final clean-room cloud rerun removed seven stale local summaries before import and exported 10/10 globally unique OKF resources; duplicate active resources now fail the round-trip evidence check. Separate live Moorcheh evidence covers the cloud round trip without publishing the API key.

Closes #1609
