Calculated vs measured evidence classes
Every engineering number is either CALCULATED (with its method and inputs) or MEASURED (with instrument, observer, time and uncertainty). A “measured” label without that evidence is refused.
LIVE-PROVEN , rung 6 of 8 Recorded 23 September 2026. Advanced Systems branch, not merged into production.
Technical
What it is
MEASUREMENT_UNVERIFIED refuses the Measured label when independent evidence is missing; calculated values list any missing lineage instead of filling it in; the HUD gives each class its own badge.

Where it stands
Rung 6 of 8: LIVE-PROVEN
A bounded probe ran the real code path on a booted JARVIS on the real machine and recorded evidence. The project treats live evidence as expiring after 24 hours, so every live reading here shows the date it was taken.
Project record: COMPLETE (atoms -03/-08/-10), canonical live proof
- CONCEPT Designed or specified. No working code yet.
- IMPLEMENTED Code exists. Nothing has demonstrated that it behaves correctly.
- TESTED Automated tests exercise it in isolation, often against fixtures.
- INTEGRATED Wired into the rest of JARVIS and tested across component boundaries.
- PRODUCTION-REACHABLE The owner can reach it through the real runtime path, not only through a test harness.
- LIVE-PROVEN A bounded probe ran the real code path on a booted JARVIS on the real machine and recorded evidence. The project treats live evidence as expiring after 24 hours, so every live reading here shows the date it was taken.
- FORMALLY VERIFIED Its critical property is checked by a proof or exhaustive verification.
- RELEASE-QUALIFIED Passed every qualification gate for a named release.
Limits
Limitations
- The “measurement” in the proof was a fixture, not a physical reading.
- There is no separate “simulated” evidence class yet.
- Proven on an isolated diagnostic core with synthetic test fixtures, not on the owner’s everyday runtime.
Record
