Storage and thelake
Managed Agent Evaluation uses thelake as the sole system of record for Softprobe workflow domain data. Framework-native result detail remains in content-addressed EvidenceArtifact bytes.
Data flow
Ledger (authoritative)
Append-only tables store:
- WorkflowVersion snapshots
- Events and state transitions
- FrameworkAttempt records and typed failures
- Artifact metadata and content hashes
- GateDecision records
- Optional projected measurements (not a Softprobe evaluator contract)
The work queue is disposable coordination state — rebuildable from nonterminal ledger records.
Object storage
Large immutable bytes live in tenant-scoped object storage (native result bundles, logs, traces). thelake stores digest, size, media type, encryption/ACL metadata, residency, retention class, and committed location.
Commit-before-reference: ledger never points at unverified bytes.
Projections
Score and run views are rebuildable from the ledger + artifacts. They may lag and may be lossy relative to native bundles. Rebuild from events; do not treat projections as SoR.
