One deployment · repeated runs inside the recorded test window.
24-hour consistencyNot measured
Workload skipped · No measured score. This report covers a 21 min test window, so no time series exists and none is drawn.

Individual runs, not medians. PostgreSQL uses the in-memory dataset. Spread within one test window does not establish long-term consistency.

Review and measurement limits
- Single deployment; not an independent three-instance cohort.
- No hardware attestation.
- Pilot memory implements read/write; copy workload deferred.
- Network endpoints must be supplied by the operator; no public third-party servers are used.
- Database latency distribution is not available from this pilot parser; average latency only.
- This profile is not a full implementation of all proposed methodology tests.
- Resource-constrained environment: CPU workers and RAM reflect affinity/cgroup limits, not host capacity. Private resource-limits evidence retains both; do not merge container/VM or architecture cohorts.
- Short profile: does not establish 24-hour consistency.
- This report received AI-assisted evidence review under user-delegated authorization. This is not independent human verification or hardware attestation.
- This pilot measures its recorded test window. It does not establish 24-hour consistency, long-term reliability or provider-wide performance.
- Network tests use two controlled London endpoints, one stream, a 100 Mbit/s rate setting and a requested 64 MiB byte target per direction. Reverse-mode polling can exceed that byte target; actual sent and received bytes govern traffic accounting. These results do not measure maximum link capacity.
- SKU and region were matched to retained deployment records. A missing detected SKU uses the operator-supplied plan and remains labelled supplied. Control-plane records and checksums do not attest the physical host or establish physical-host independence.
- Package versions and available guard and journal evidence were reviewed. These records do not establish continuous absence of package activity throughout the test window.
- The pilot includes memory read/write and average PostgreSQL latency. Memory-copy tests and PostgreSQL latency percentiles are not implemented. Skipped consistency and missing measurements are not scores.
