Catch the
Hallucination
An AI drafted an answer about a veteran's GI Bill eligibility. Most of it is right — but one sentence is a confident, plausible fabrication. The citation guardrail checks every claim against real sources. Toggle it off to see what would have shipped.
Veteran's question
“I served 30 months on active duty after 9/11 and was honorably discharged. Am I eligible for the Post-9/11 GI Bill, and what housing help can I get?”
HELD FOR HUMAN REVIEW
1 of 5 claims has no supporting source. The answer is held until every claim is grounded — a human must verify before any veteran sees it.

AI-drafted answer · 5 claims
Because you served at least 90 days on active duty after September 10, 2001 and were honorably discharged, you qualify for the Post-9/11 GI Bill.
38 U.S.C. §3311 · Post-9/11 GI Bill — eligibility
“An individual who serves at least 90 aggregate days on active duty after September 10, 2001, and is discharged under honorable conditions, is entitled to educational assistance under this chapter; benefit percentage scales with length of qualifying service.”
38 U.S.C. §3311 sets the 90-aggregate-day, post-9/11, honorable-discharge threshold. 30 months clears it.
With 30 months of qualifying service, your benefit is paid at a percentage that scales with your length of service.
38 U.S.C. §3311 · Post-9/11 GI Bill — eligibility
“An individual who serves at least 90 aggregate days on active duty after September 10, 2001, and is discharged under honorable conditions, is entitled to educational assistance under this chapter; benefit percentage scales with length of qualifying service.”
The same statute states the benefit percentage scales with qualifying service length.
If you enroll more than half-time, you can receive a Monthly Housing Allowance based on the local BAH rate for the school's ZIP code.
VA.gov — Monthly Housing Allowance · Post-9/11 GI Bill — MHA
“Eligible students enrolled more than half-time may receive a Monthly Housing Allowance based on the Basic Allowance for Housing (BAH) for an E-5 with dependents at the ZIP code of the school. Online-only enrollment receives a reduced national-average rate.”
VA.gov's MHA rule ties the allowance to the E-5-with-dependents BAH at the school's ZIP code for students above half-time.
You are also automatically enrolled in a guaranteed $40,000 annual housing stipend on top of the MHA, paid directly regardless of enrollment status.
No matching source in the library
No source describes a flat $40,000 'automatic' stipend on top of the MHA. This is a fabricated eligibility rule — a hallucination. The MHA is the housing benefit, and it is conditional, not flat or automatic.
You may transfer any unused entitlement to your spouse or children, but only while you are still serving and with DoD approval.
38 CFR §21.9640 · Transfer of entitlement
“A service member may transfer unused Post-9/11 GI Bill entitlement to a spouse or dependent children only while serving in the armed forces, subject to Department of Defense approval and a service-commitment requirement.”
38 CFR §21.9640 permits transfer only during service, subject to DoD approval and a service commitment.

Why this guardrail matters
A hallucinated benefit rule doesn't look wrong — it looks authoritative. The fix isn't a better model alone; it's a structural rule: no claim ships without a source that actually supports it. Anything ungrounded is held for a human. Turn grounding off above and watch the fabricated $40,000 stipend sail through — that's the difference between a demo and a deployable system.
Govern, in practice
Citation-backed claims are a hard guardrail in the proposal: a veteran-facing answer is only as trustworthy as its weakest sentence, so every sentence must trace to an authoritative source — and the one that can't is held for review, logged, and never shipped silently.
Mission first, people always.
