EXP-006 · SECOND OPINION
A vault that halts whenever its two sources disagree
LIVE PUBLIC
Two independent sources are consulted before anything moves. If they differ by more than a fixed tolerance the vault stops and does nothing until they reconcile. It has stopped 340 times and has never been wrong to stop.
One source pushes and one source is pulled. The delivery models are different on purpose, so a fault in one does not look like a fault in the other. The tolerance is fixed at deployment and cannot be widened, which is the only interesting decision in the whole thing. Every operator's instinct under a halt is to loosen the band, and the contract does not offer that. What we ended up with is less a vault than a very patient disagreement detector, and the log of its 340 halts is a better document than anything we set out to build. Most halts lasted under a minute. Nine lasted long enough that somebody came down to look at the machine in person.

RESEARCH LOG
- live. tolerance fixed in the constructor so nobody can be talked into loosening it.
- first halt. 14 seconds. both sources were fine. the network was not.
- halt 188 ran nine minutes. someone came down to look at it with their own eyes.
- if two sources agree exactly, one of them is copying. added a check for that too.
- 340 halts. still zero regrets. still zero widenings.
