Riverside path — north gate pothole

Two nearby reports merged into one pothole repair. Three sealed bids revealed, deterministic scoring selected contractor B, a human inspector accepted completion, and the 10% durability holdback released after a second human inspection. The completed repair stays attached to passport PATH-006.

Riverside path — north gate WO-PATH-001-0002 contractor-b….testnet

Fixture fallback. The live API has no case record for this id; the frozen replay fixture is shown instead. No live transaction, attestation or physical verification is claimed.

Current state · plain language

The durability inspection passed, the holdback released once and the work order is financially immutable.

Next: No further payment is possible. The history remains in the asset passport.

What the contractor is allowed to do

Scope, budget, roster and scoring policy were authorized together. AI may propose; it cannot approve.

DAO #49 · APPROVED

Clean and square the pothole on the riverside path at the north gate. Fill with hot-mix asphalt, compact the base, seal the edges flush with the surrounding path, and leave the route clean and passable. Submit six-item redacted evidence.

DAO authorization is a push path: a Sputnik FunctionCall proposal executes dao_authorize only after approval. MEND does not trust proposal text. This replay reference is not a live proposal lookup.

A completion payment and holdback are calculated exactly once. A closed work order cannot be paid again. A warranty reopening creates no new escrow.

A completeness review can identify missing checklist items. It cannot certify physical quality and it never supplies the human acceptance decision.

Verification ledger

What is verified, what is unavailable, and what is a human claim

REPLAY RECORDING
Verified inference evidence

Cryptographically checked inference, execution or transaction evidence.

Unavailable evidence

Expected evidence that was not available, not bundled or not verified. Never shown as verified.

Human decision

A named human decision. A human signed or explicitly confirmed it; AI did not.

Physical claim

A claim about the physical world. It is not machine-certified and does not imply structural safety.

Private AI triage

NEAR AI Cloud · structured output only

Unavailable evidence

Structured classification identified a pothole / path-surface defect, proposed a 93% duplicate candidate and drafted a low-risk repair scope. Raw media stayed private; AI did not approve the scope or any payment.

Replay recording. No live NEAR AI response signature is bundled, so this artifact is shown as unavailable rather than verified.

AI proposes classification, duplicate candidates and scope. It cannot approve scope, award a bid or move money.

OutLayer deterministic execution

Hash-pinned WASM · no LLM ranking

Unavailable evidence

Policy, WASM, input and output hashes are displayed below. The contract would accept only a hash-bound callback from the configured OutLayer account.

Replay recording. The deterministic ranking can be reproduced from the frozen bids, but no live OutLayer callback is claimed.

A live result would be accepted only through the configured OutLayer callback and matching policy, WASM, input and output hashes.

A named decision is not the same as a cryptographic signature. Replay fixtures label human actors but do not bundle their wallet signatures.

Physical-world claims

Physical claim

MEND does not certify structural, electrical or gas safety. Physical claims remain the responsibility of the named contractor and human inspector.

Why hashes matter

Hashes bind the displayed evidence to bytes without publishing private media. The hash alone does not prove a physical repair. It proves that the referenced bytes were the bytes evaluated or recorded.
