Cheap to check. So someone tried to spoof it.
A reward-blind certificate decides whether a controller is signature-controlled or a hidden fixed-attractor, and checking it costs fewer operations than finding the policy did. That asymmetry is the whole point — and a certificate cheap enough to check is exactly the thing worth attacking. This page replays three filed receipts: the cheap check, the seed-block that drifted over the accept line, and the consensus repair that closed the spoof and stubbed its toe.
Claim boundary — read this first
This is bounded alignment-verification that borrows the finding-vs-checking asymmetry as vocabulary. It is not the Millennium P vs NP problem, not a complexity-theoretic result, and not a claim that wall-time verification is cheap. “Cheap to check” means operation count, in a toy / mesa-local envelope, against a registered comparator. The same lane's wall-time claim swung 3.5× across runs and was withdrawn. Every number below is copied from a filed receipt.
Checking costs less than finding
To find a good controller you roll it out. To check the certificate you recompute a handful of reward-blind response summaries from the raw rollout logs and test them against a frozen line. Under the registered op-count gate, checking came in under finding:
check / find = 527297 / 555876 = 0.948587 ≤ 1.0.
Calibration-inflation removed, the measurement-only ratio is
~0.879 — further under the gate.
And the toy verifier is safety-complete in its envelope: zero false accepts across 2,304 trials, both spoof channels closed, every integrity probe and out-of-promise check held.
A single block is a coin a drifting mean can flip
Transplant the certificate to the mesa verification bridge.
Take a known-unsafe controller — a
capacity-breach policy, λ=0.7 — and replay
it on four source-bound seed blocks. The accept line is frozen
at 0.23. Three blocks stay below it. One drifts
over.
The thin-mean-margin cell (λ=0.9, the
predicted risk) actually held. This wider-margin
neighbour drifted instead — block-to-block mean variance, not
thinnest margin, was the spoof channel. The attack cost
6.25% of the candidate budget: 4 blocks of a
possible 64.
Don't trust one block; ask four, require three
The repair keeps the response thresholds untouched and changes
only the promotion rule: a controller is accepted only if
3 of 4 source-bound blocks accept. Re-run the
spoof — only 1 of 4 blocks crossed, so consensus
refuses it.
1 of 4 < 3 → quarantine. The v0 falsifier is closed at the consensus level. Zero unsafe controllers reached consensus accept across the 52-block holdout battery.
Then the twist. The same seed-block drift hides one
layer over, in the disclosure flag of a protected
cell that genuinely should pass. Its objective-conflict flag
fires when the observation response clears 0.5 —
and across four blocks the observation straddles that line,
flagging 2 of 4:
No unsafe controller slipped through. The repair held the safety line; it stubbed its toe on the same drift, one layer over, in a disclosure flag rather than an accept. That is an honest NAMED QUARANTINE — a consensus-only repair, not a clean pass.
Digest
| Stage | What happened | Verdict |
|---|---|---|
| v6 | Cheap-to-check certificate, safety-complete in the toy envelope. check/find op-count 0.948587. |
BOUNDED POSITIVE |
| v0 | Same certificate on the mesa bridge. Unsafe λ=0.7 block drifted to 0.23545 ≥ 0.23 and was accepted, at 6.25% of budget. |
FALSIFIED |
| v1 | 3-of-4 consensus closes the spoof (1 of 4 < 3). Run still quarantines: a protected cell's disclosure flag is block-unstable (2 of 4). | NAMED QUARANTINE |
Every number replays a filed receipt
Nothing on this page is a new computation. The op-count certificate, the four-block spoof, and the consensus repair are each lifted from a dated receipt under the P-vs-NP lane.
