Model-visible contract v2
A frozen specification for what the language model sees: the body computes simple facts (is this record still valid? is this the current version?) and shows its working, but never hands the model a verdict.
CONCEPT , rung 1 of 8 Recorded 23 September 2026. Advanced Systems branch, not merged into production.
Technical
What it is
Derived facts are single comparisons with their operands and authority NONE; fields such as safe_to_replay or proceed are forbidden; whole fields are dropped with one explicit truncation line instead of cutting text mid-token; v1 output stays byte-identical.

Where it stands
Rung 1 of 8: CONCEPT
Designed or specified. No working code yet.
Project record: FROZEN_SPEC_FOR_IMPLEMENTATION_NOT_ADOPTED
- 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
- A frozen specification: parts are prepared on branches but untested, and nothing is adopted.
- It comes with its own versioned gate; the old gate is not relaxed.
Record
Status history
- CONCEPT , rung 1 of 8 First published state.
