0062 — Economy: tariffs, contracts, and market-data hardening (Group F)¶
Status¶
Folded into market-pricing.md, contracts.md, black-market.md, bang-integration.md, economy.md, mining.md — 12/12 items closed. Defer to those pages for the canonical description (E-F1, E-D1, E-D2, E-D3, E-F2, E-F3, E-F4, E-I1, E-I2, E-I3, E-V4 live; E-V1/R-V2 closed 2026-08-04 via contracts.md's single-acceptor terminal-walkaway locker model, which closes the SK13 re-delivery exploit by a stronger mechanism than the ADR-0049 monotonic counter originally asked to cross-link — see Decision § E-V1). (re-verified 2026-08-04)
Context¶
Twelve audit findings clustered around the economy surfaces — tariff knobs, contract walk-away exploits, market-data gaps. Two were critical (tariff arbitrage cycle, walk-away re-delivery); the rest were correctness, table-completeness, and policy-gap fixes that composed cleanly into one ADR. E-V1 and R-V2 referenced the same fix and collapsed into one work item.
Folded into: ../SYSTEMS/market-pricing.md, ../FEATURES/economy/contracts.md, ../FEATURES/economy/black-market.md, ../OPERATIONS/bang-integration.md, ../DATA_MODELS/economy.md, ../FEATURES/economy/mining.md — defer to those pages for the canonical description of E-F1, E-D1, E-D2, E-D3, E-F2, E-F3, E-F4, E-I1, E-I2, E-I3, E-V4.
E-V1 / R-V2 note: the originally proposed fix (ADR-0049 SK13, a monotonic Contract.fulfillment_count counter) was superseded by a stronger shipped mechanism — contracts.md's single-acceptor terminal-walkaway locker model, which closes the SK13 re-delivery exploit without the counter. See contracts.md § Bulk procurement.
