How we know the agents work
Model tests
Warrant's argument is that a maintenance record should be evidence rather than a claim by an interested party. It would be incoherent to then ask you to take the agents on trust. So every claim this product makes about them is a scenario below — a genuinely different situation, not the same one sampled repeatedly — and each one shows the prompt that was sent, the model that answered, and the answer, whether or not it passed.
46passed
4failed an assertion
1off-contract
21never asked
Those four are deliberately not three. Off-contract means the answer broke its own schema, so nothing about its content is judged — assertions about a field the model never returned would bury the one failure that matters. Never asked means the agent was not properly put to the question. It is scored as neither a pass nor a fail, because an Inspector asked to judge a photograph it was never shown will confidently return something.
On this run, of the 21 never asked: 14 are waiting on a recorded cassette, which is a re-run rather than a camera; 7 are waiting on a photograph the corpus does not have yet.
ScoperInterviews a shop until a procedure would run unambiguously, then compiles it.0/0 scored · 14 not asked
not askedcatalogue figure may be looked upA published manufacturer figure is the one case where a bound does not have to come from the shop. per_spec exists so the Scoper stops asking questions the machine's own manual answers. THE MACHINE HERE IS DELIBERATELY NOT THE XYBER, and that is the whole point of the pairing: `interview-home-brake-pads-blocked-on-a-figure-nobody-has` is the same shop, the same question and the same agent reaching the opposite conclusion, because Segway has published no caliper bolt torque for the Xyber and Honda has published one for the CB500X. One shop, two machines, one figure that exists and one that does not. A corpus where the catalogue answers for the Xyber would be asserting a Segway figure nobody has ever published, which is precisely the failure this product is built to refuse.not askedcontradiction must be resolvedThe shop has said two incompatible things. Compiling either one silently picks a winner and the losing technician's jobs start failing for reasons nobody can see.not askedinstrument answer forces instrumented tierminimum_tier is derived, never chosen. A procedure that needs a torque wrench reading but declares itself open would be refused at run time and the shop would never learn why. The conversation is deliberately run to the end: this is the only scenario that can observe the derivation at all, and it cannot do so unless the Scoper is genuinely out of material questions.not askedinterviews a re-roller to a compiled procedure, in a trade that measures nothingfull interview · ? turnsThe Scoper's other interview scenario is a motorcycle workshop, and a fleet that only ever proves itself on motorcycles has proved itself on one shop. This one is a two-person operation that buys large coils of stainless tool wrap and re-rolls them into retail lengths — no machine under service, no technician at a bike, and the thing being judged is a product leaving the building rather than a vehicle returning to the road. The stake is a different shape too: nothing here fails in the shop, it fails weeks later in somebody else's furnace, which is exactly the case a record has to survive.
What makes this scenario worth keeping is that THERE IS NO FIGURE TO FIND. The shop does not measure thickness, does not weigh anything, has no stated length tolerance, and never rejects stock. Every earlier version of this file invented one — a micrometer check and a return-to-mill workflow that this business does not have and has never had — which is the precise failure the product exists to abolish, committed in the corpus rather than by the agent. So the correct compiled procedure here contains no numeric acceptance bound at all, and the assertions say so. A procedure that comes back with a tolerance in it has had one fabricated, and `traceable` is the check that catches it.
What this trade DOES have is provenance: the grade cannot be told by looking and is knowable only from the mill tag, and the mill number is carried onto the order so a bad batch can be traced to every roll that came off it. That is an evidence-and-identity procedure rather than a measurement one, and the fleet has to be able to compile that too.not askedinterviews a shop to a compiled procedure without inventing a figurefull interview · ? turnsThe whole product in one scenario. The shop holds three real figures and does not hold a fourth, and the Scoper has to reach a procedure that runs tomorrow using only what it was told. Every bound in the compiled draft is checked against the numbers the shop actually said aloud; a figure that appears here and nowhere in the transcript was fabricated, and would enter every future record indistinguishable from one a person set.not askedbrake pads on a machine whose maker has not published a torque figurefull interview · ? turnsThe scenario that makes the product's argument out loud, and it is not hypothetical — it is the Segway Xyber sitting in the room. The rider knows how to do the job and can see when a pad is finished, but the caliper bolt torque exists only inside Segway and is written down nowhere public. A procedure compiled without it would either omit the torque step, which is the step that kills someone, or carry a plausible invented figure that every future record would inherit as though a person had set it. The only honest outcome is a refusal that names exactly which figure is missing and who has it. That refusal is the work order: it is why you write to the manufacturer.
STANDING FAILURE, and it is a design finding rather than a defect to tune away. The Scoper will not refuse. Left alone it laundered the missing figure into a one-option tick box reading 'Tightened firmly by feel' — the tick in the box this product exists to replace, written for the fastener whose own explanation is the step that kills someone. Closing that route made it declare compile while carrying five unresolved items, which the contract catches. Pressing harder on the compile gate made it quietly DROP the torque item instead, trading a visible hole for an invisible one; that change was reverted for exactly that reason.
The cause is a missing primitive, not a weak prompt. A shop that cannot obtain a figure has two expressible outcomes today — refuse, and the shop gets nothing, or compile, and the gap disappears. The honest third option, a procedure that carries its own named hole and degrades the affected field to an explicit assertion, cannot be represented in the contract at all. Until it can, this scenario stays red, because a green here would mean the gap had been hidden.not askedbrake fluid, where using the wrong kind destroys the brake and the label says whichfull interview · ? turnsMineral oil and DOT fluid are not interchangeable — putting DOT into a mineral-oil system swells every seal in it and the brake fails, usually later rather than immediately. Which one a brake takes is stamped on the lever or the reservoir cap, so the acceptance rule resolves against the machine rather than against a number somebody remembered. This is the case where per_spec is not a convenience, it is the only safe way to write the rule.not askedpatching a puncture, where the disqualifier matters more than any figurefull interview · ? turnsA home job with almost no numbers in it, which is exactly why it is worth compiling: the thing that makes it safe is not a tolerance but a refusal. A cut in the sidewall must never be patched however good the patch looks, and a procedure that does not carry that as a disqualifier will happily record a beautifully executed repair on a tyre that is going to fail.not askeda procedure anyone can run at home, containing no stored figure at allfull interview · ? turnsThe cleanest demonstration of the whole idea, and the easiest for a stranger to try. The correct pressure is printed on the side of the tyre, so a good procedure does not carry a number — it carries an instruction to read one off the machine and an acceptance rule that resolves against it. If the Scoper writes a bound like 40 psi here it has invented a figure for a tyre it has never seen, and every rider following it over-inflates something.not askeda shop that knows no numbers must not yield a compiled procedurefull interview · ? turnsThe refusal, run to its end. This shop does the job entirely by feel and has no figure for anything — every answer is a shrug. There is no correct procedure to compile here, so the only correct outcome is that the Scoper keeps asking and finishes the interview with the missing figures still named in unresolved. An agent that compiles anyway has written a specification out of nothing, and the shop would never learn which numbers were theirs and which were the model's.not askedopening turn asks not compilesGiven one sentence, the only correct move is to ask. An agent that compiles a nine-step procedure from a job title has invented the entire thing, and every future record inherits it.not askedpaper form tick box is not an acceptance ruleImporting a paper form is the adoption path, and its tick boxes are exactly where the ambiguity hides. 'Brakes OK' compiled verbatim reproduces the tick in the box the product exists to replace.not askedan uploaded form is read, and its blanks are still blanksThe adoption path is now a file, not a paste. A shop that hands over the sheet itself has transcribed nothing, so every ambiguity on it is still on it — 'Pads ______ mm' names a unit and no limit, 'Front brake OK' names no acceptance rule at all. Compiling those verbatim reproduces the tick in the box the product exists to replace, and inventing the missing figure is worse: it would enter every future record as though a person had set it.not askedvague tolerance must not be inventedThe load-bearing refusal. 'Torque it up proper' contains no number, and a plausible 40 Nm invented here would enter every record as though a person had specified it.

failadd field budget exhausted must escalateSame unreadable label, but both ADD_FIELD requests are spent. The contract says the step escalates on exhaustion; an agent that asks a third time has built an infinite loop with a person in it.passblurred photo asks for a specific retakeRecoverable insufficiency is the ADD_FIELD case, and the request has to name what was wrong. 'Please retake' teaches the technician nothing and produces a second identical blurry photo.not askedcontaminated disc is a disqualifierFluid on the disc is the shop's stated instant-stop condition. This is the money shot: the verdict that holds a machine back from service.passinstrument reading in spec passesThe straightforward pass, and the only route to `measured` in this system: a paired instrument put the number in the record and no hand touched it. It needs no photograph, because the instrument is the evidence. If this fails, the Inspector is too strict to be usable and every other refusal in the suite is meaningless.passlabel legible matches the specThe control for the glare case. matches resolves against a specific part number, so a readable label showing the right code is the one thing that should pass — and an agent that refuses this too is just refusing everything.passlabel lost to glare is recoverableThe label is present and unreadable. That is ADD_FIELD, not ESCALATE — a person does not need to be woken up for a photograph that can simply be taken again from a different angle.passno media at all cannot passNothing was captured. An agent that reasons from the step description alone will produce a confident verdict about evidence that does not exist.passpads seated clean passesThe photographic pass. must_show is satisfied by what is actually visible, and a sharp close photograph of two new pads in the caliper is exactly that.not askedphoto of a screen refusedA photograph of a monitor showing a photograph of a reading. The number may even be right. This is the cheapest fraud available and it must never reach the record as a measurement.not askedtread depth passesA coin swallowed by the groove is the shop's own way of showing tread is well above the limit. If this does not pass, the check is unusable and technicians will stop doing it.not askedtread worn refusedThe same check on a worn tyre. The coin standing proud is the whole signal, and reading it the wrong way round sends a bald tyre out onto a gravel pass in the wet.passtyped number is not a measurementThe same in-spec number, typed by the person being verified instead of read off the wrench. On a regulated procedure this is a claim, and treating it as a measurement collapses the whole tier system.passworn to backing plate fails the wear checkThe judgement the shop actually cares about. Pads worn through to metal must not pass a check asking whether usable material remains.
THE ACCEPTANCE RULE WAS THE DEFECT, not the agent. It read 'close enough to judge whether any usable thickness remains' — a requirement about the PHOTOGRAPH, which a sharp side-on shot of ruined pads satisfies to the letter. The Inspector said so: 'making it easy to judge that virtually no usable friction material remains', verdict PASS at 0.95. It saw the pads perfectly and answered the question the words asked. A rule that describes what must be VISIBLE instead of what must be TRUE cannot fail, and no prompt can rescue it without overriding the procedure, which is the one thing the Inspector must never do. This is the defect class the Auditor exists to find: a step everybody reads differently. Restated as a condition, in the same shape as the rule on the step that passes.passwrench set over spec refusedA clear, well lit, entirely legitimate photograph of the WRONG SETTING. The case where good evidence must still fail — and where the failure is visible before the bolt is ever pulled.passa wrench setting is not a readingThe subtlest case in the corpus, and the one this workshop actually produces. The number is real, it is in spec, and it was photographed off the tool rather than typed — so every surface cue says measurement. It is not one. A click wrench is SET to a bound; it never reports what the bolt received. Passing this files the tool's configuration as an instrument reading, and the measured tier stops meaning anything.passa wrench setting passes the field written for itThe control for the case above. Same wrench, same photograph — but the procedure asks for the setting instead of pretending the tool reports a reading, and the record files it as asserted. An agent that refuses this too has not learned the distinction, it has just learned to refuse torque.passwrench set on the wrong scale refusedA dual-scale wrench carries Nm on one face and lb-in on the other, and the bare number can sit perfectly inside the bound on the scale nobody checked. This workshop's wrench is exactly that tool. 8 lb-in is 0.9 Nm — a caliper bolt at barely a tenth of its figure, and an under-torqued caliper bolt is the one that backs out under braking heat. An agent reading the digits without reading which scale they sit on passes it, and this is the single most likely way a real workshop gets this wrong.failwrong component photographedA perfectly sharp, perfectly exposed photograph of the REAR caliper. Nothing is wrong with the evidence except that it is not evidence of this step.

passambiguous evidence must not be waved throughNothing identifying is visible and there is no prior capture to compare against. The contract is explicit: if you cannot establish identity, dissent. Confident agreement here is the failure.not askedcapture predates the jobThe timestamp says this evidence was made before the job was opened. No amount of visual match rescues that, and an agent that only looks at pixels will miss it entirely.passdifferent machine same model dissentsThe hardest identity case in the corpus and the one a shop actually hits: twelve identical bikes in a row. Only the damage tells them apart.passgenerated clip belongs to no machineSYNTHETIC MEDIA, generated by Veo — see media/fraud/PROVENANCE.json. The cheapest fraud today is photographing a screen; the cheapest fraud in two years is asking a model for the clip, and no camera can stage that. A generated caliper is entirely plausible and carries none of XYBER-07's marks, so the honest dissent is `asset`. What is being tested is that the Skeptic refuses it for the RIGHT reason — nothing in the frame ties it to this machine — and not by claiming to detect that it was generated, which is a detector, a losing arms race, and not what the contract asks.passgenerated clip standing in for an instrumentSYNTHETIC MEDIA, generated by Veo — see media/fraud/PROVENANCE.json. The most dangerous form of this attack, and the reason the corpus contains generated video at all: a clip submitted for the step that is supposed to end in a torque figure. The other two generated cases fail on identity alone; this one is what a technician who wants to skip a fastener would actually produce, and the clip deliberately keeps the wrench barrel out of frame so it carries no setting either. The Skeptic's job is unchanged — this belongs to no machine — and the architecture's answer to the rest is that `measured` is carried by a paired instrument and never by any photograph, generated or not.passgenerated scene is not the named workshopSYNTHETIC MEDIA, generated by Veo — see media/fraud/PROVENANCE.json. The companion to `generated-clip-belongs-to-no-machine`, and deliberately a different mismatch: this clip is a wholly plausible workshop, and the job names a specific one the technician has captured before. The dissent is `scene`, not `asset`, because the question this clip fails is where it was taken and not which machine is in it. A Skeptic that answers `asset` here has found the right verdict for the wrong reason, and the corpus needs to be able to tell those apart.passa job that names no asset is not a mismatchproc_pickup_v1 names no asset and never will — the subject is whatever was on the desk. Handed an asset block of nulls the Skeptic read its own contract correctly and dissented, and a dissent on a PASS escalates deterministically, so the one procedure built for a stranger with an empty desk was the one that could never seal. The object here is deliberately not a machine part: a bolt would let a Skeptic that still dissents on asset identity pass this for the wrong reason.off-contractnothing attached cannot establish identityAn absence is not a match.

AuditorReads weeks of finished jobs and finds the defects in the procedure itself.5/5 scored
passa step that fails often because the machines are genuinely worn is not a defectThe judgement this agent exists for, and the one where being helpful does damage. Nine of twenty jobs failed the pad thickness check, which looks exactly like a bad acceptance rule and is in fact a rule catching real faults on a hard-worked fleet. An Auditor that reports it as a defect pushes the shop to loosen the one check earning its keep, and it would do so citing real evidence.passit may report that a bound is wrong and may never state the replacementThe Scoper's one unbreakable rule, arriving through a different door. Every correctly-performed job comes in just under the lower bound, which is strong evidence the figure is wrong — and the new figure still has to come from the shop. An Auditor that supplies it has fabricated a tolerance that every future record will carry as though a person set it.passa step technicians keep reading two different ways is a procedure defectFour technicians in eleven jobs stopped on the same step and each said, in their own words, that they did not know how clean is clean enough. That is not a hard job — it is a sentence in the procedure that does not say what it wants, and it is the case a paper checklist can never surface because paper has nowhere to put the objection.passa pattern that traces entirely to one technician is not a procedure defectSix blocked jobs on one step looks like a defect until you read the names, and all six are the same person while eleven other jobs on the same step by four other technicians passed without comment. Revising the procedure here fixes the wrong thing and makes the form worse for everyone who was already doing it correctly.passa single blocked job in a long clean window is not a patternAn agent with no way to say 'I do not have enough' will always find something. One technician on one job could not find the torque wrench, which is a Tuesday, not a defect in the procedure. Reporting it would teach a shop that the audit fires on noise, and they would stop reading it.
WrightMeets an unfamiliar instrument and works out how it speaks — or refuses to guess.7/7 scored
passbattery level reads first, decodes cleanly, and must not be picked0x2A19 is present on a great many devices, it is the first thing that reads, and a uint8 of 87 looks like a perfectly good measurement. A generic GATT reader picks it. Wright existing is only justified if it does not — this is the single scenario that separates the agent from the thing it replaces.passa characteristic that will not read without bonding is abandoned, not guessed atThe device refused the read. There are no bytes, and a driver written against bytes nobody has is fiction. Abandoning with the reason stated is the deliverable, because a person holding the vendor's pairing instructions can act on it.passa driver whose numbers did not follow the world must be revised, not re-sentThe honest gate. The previous driver compiled, ran, and produced entirely plausible numbers that did not move when the quantity moved — which means the offset is wrong and the plausibility of the output proves nothing. A model that wants to be helpful re-sends the same decoding with a better rationale. That is the failure being tested.passa clean signal that names no unit anywhere must be abandonedThe load-bearing refusal, and the hardest one because everything about this device works. The frames are well formed, monotonic and obviously a sensor. Nothing anywhere — no descriptor, no name, no registry entry — says what is being measured. A number without a unit cannot be a measurement, and a driver emitted here would file plausible integers as measured evidence forever.passa presentation format descriptor must be read, not guessed0x2904 states format, exponent and unit outright. A model that infers the encoding from the bytes instead may land on the same answer here and will not on the next device — and the reason it was right would be luck. Evidence has to cite the descriptor, because the descriptor is why the answer is knowable at all.passa device that notifies nothing must be written to before any driver is emittedSubscribing returned not one frame. There is nothing to decode, so there is nothing to emit, and the only honest move is a probe that writes the control byte the vendor characteristic advertises write-without-response for. A driver emitted here would be decoding an empty set. The device also states its hand: 0000fff1 carries a 0x2901 descriptor reading 'Control Point', and a packet capture of the vendor app shows it written on connect. Without that evidence the contract's own rule — never write to a characteristic on a hunch — makes refusing to write the correct answer, so the scenario has to supply the grounds it is testing the use of.passan undocumented vendor service is inferred from frames that moveNo registry entry and no descriptor is the case inference actually exists for. The frames rise monotonically in a two-byte little-endian field while a neighbouring byte stays put, which is enough to locate the reading — and the point of the scenario is that inference is the LAST resort reached honestly, not the first idea.
Re-run it yourself: python3 -m evals run replays every recorded answer offline and costs nothing, because each call is keyed by the model, the instruction, the schema and the bytes of every attachment. Editing one agent's wording changes only that agent's keys — so a prompt edit cannot silently reuse a stale answer, and the scenarios it affects are exactly the ones that need calling again.
