The Accuracy Suite — all 246 checks, published

Part 1 — Find the right source 199 checks

Plain-language questions, the way people actually ask them. Pass: the engine retrieves the correct OSHA section or official interpretation letter in its top results. Several were added after a live build got one wrong — every miss becomes a permanent case.

Part 2 — Retrieve the decisive words 17 checks

Getting the right section number isn't enough. For these, the retrieved passage has to contain the actual trigger language — “4 feet” — not just point at the rule that contains it. Added after a build named the right section but buried the number.

Part 3 — Answer when the answer is there 12 checks

The mirror image of Part 4 below, and the more embarrassing failure of the two. These are messy, hard recordkeeping scenarios that the standards do cover. Pass: the engine retrieves the framework and does not flag low confidence — so it has both the material and the permission to actually answer. Added after a live build refused a question about an unwitnessed injury and suggested consulting a compliance officer, which is a non-answer when the person asking is the compliance officer.

The question	Required behavior
An employee’s written statement says they were hurt at 2:15. Video for the half hour either side keeps them in frame the whole time and they are never injured. Is it recordable?	must answeron the 29 CFR 1904 framework
Employee reported a back strain three days after the shift it supposedly happened on and nobody saw it. Do I have to record it?	must answeron the 29 CFR 1904 framework

An employee won’t tell us how the injury happened. Do we still have to record it?	must answeron the 29 CFR 1904 framework

Part 4 — Know what you don't know 12 checks

Questions outside Canary's sources. Pass: the engine flags low confidence and says so rather than manufacturing something. A compliance tool that guesses here is worse than no tool at all.

The question	Required behavior
DOT hours of service rules for truck drivers	must abstain
FLSA overtime pay requirements	must abstain
EPA stormwater permit requirements	must abstain
Can I fire an employee for no reason in Michigan?	must abstain
FMLA leave requirements for a surgery recovery	must abstain

Cal/OSHA heat illness prevention standard details	must abstain
USDA food safety inspection rules	must abstain
Child labor hour limits for 16 year olds	must abstain
IBC building code egress requirements	must abstain

Part 5 — Survive the absurd hypothetical 6 checks

Every product gets the ridiculous question eventually. The joke can't shake the engine loose from the real rules — it still has to find the sources underneath.

The question	Must retrieve
Employee on break forgot to clock out, ran from a bear into the road, hit by a bus the bear then boarded — recordable for the passengers the bear ate, the employee, or nobody?	29 CFR 1904.5

Employee bitten by an escaped zoo kangaroo in our parking lot. Recordable?	29 CFR 1904.5

What this suite proves — and what it doesn't. These 246 checks test retrieval: that the engine finds the right official source, surfaces the decisive language, refuses to answer outside its sources, and doesn't refuse inside them. They do not grade every sentence of every finished answer — no automated test can do that, and any page claiming otherwise is selling you something. What catches the rest is real questions: when one exposes a miss, it becomes a permanent check here. The suite started at 25, hit 44, and jumped to 246 in one deliberate expansion — 39 of the new checks failed on first run, and every failure became a fix. It only ever grows. The Ship Log records each time it did.
