30-day endurance objective — exceeded
31+ days. 1.2 million confirmed envelopes.
PQCore's long-duration post-quantum envelope test completed successfully and exceeded both original objectives: more than one million confirmed envelopes and more than thirty days of continuous endurance operation. The harness was deliberately stopped after completion, leaving the final evidence set read-only.

What the run demonstrated
Endurance is measured over time, not in a single successful burst.
The test exercised the PQCore processing chain continuously over the endurance window while preserving an ordered, timestamped evidence trail.
The one-million-envelope objective was exceeded with 1,206,310 confirmed R-53 evidence records, 206,310 above target. The harness also continued beyond the thirty-day endurance objective. The final published evidence record reached ledger sequence 1,413,553.
01
Continuity
Observe sustained operation over days rather than relying on a one-time demonstration.
02
Measurability
Maintain clear counts, timestamps, and completion evidence throughout the run.
03
Traceability
Preserve an ordered integrity reference for every published evidence record.
