Rung 2 of 8: IMPLEMENTED
Code exists. Nothing has demonstrated that it behaves correctly.
Qualified as PARTIAL: part of this capability is not at the rung shown.
Project record: IMPLEMENTED
- 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.

- Semantic end-of-turn JARVIS decides when you've finished talking from meaning, not only silence.
- Barge-in stop ≤120 ms You can interrupt JARVIS mid-sentence and it stops quickly.
- Preserve-heard / cancel-unheard When interrupted, JARVIS remembers what you actually heard and drops the rest.
- Truthful text fallback If speech output is unavailable, JARVIS says so in text instead of failing silently.
