Marketplace & Bidding04

Every object, bid and allocation keeps its order.

VDC objects, QR identity, transparent bids, deposits, pickup and settlement live in one evidence line.

04Object identity

Object identity

A design object or offer keeps one identity across seller file, showroom label, QR, marketplace and pickup point.

INTERACTION→CORE CONSEQUENCE→EVIDENCE

Bid sequence

Every bid is checked atomically for actor, time, minimum step and ordering so no later write can secretly overwrite an earlier truth.

A real situation, end to end · MKT-03

A bid keeps its place from intent to allocation.

Follow one authorised result from the first signal to durable evidence.

01Signal
Places a bid.
02OPS context
Checks identity and asks confirmation.
03Human authority
The bidder confirms amount, object, deadline and binding intent after identity and bid-step checks.
04Bounded handoff
OPS submits only the signed bid payload and authority proof; strategy, drafts and unrelated financial context stay private.
05CORE record
Validates time, order, step and authority atomically.
06Shared consequence
No hidden overwrite can change bid order.
07Durable evidence
Bid evidence preserves exact order, amount, object version, bidder authority, timestamp and rejection of conflicting writes.

System boundaryOPS keeps the operational context. NUMA may assist inside that context. Only the approved, scoped and attributable result crosses into CORE.
