### D-171: Three-Currency System
|
||||
- **Date:** 2026-04-05
|
||||
- **Decision:** The Settled Reach uses three currencies with distinct political identities and geographic zones:
|
||||
- **Tractus** — issued by the Concord Assembly (Sirius / Groombridge origin). The Reach-wide standard currency. Accepted everywhere. Numeraire for all simulation pricing. The establishment currency.
|
||||
- **Tractus** — issued by the Concord Assembly (headquartered at Sirius). The Reach-wide standard currency. Accepted everywhere. Numeraire for all simulation pricing. The establishment currency. Groombridge hosts the clearing house (D-175 Tier 1 gap) but is not a co-issuer.
|
||||
- **Mark** — issued by the Compact of Westphalia. Created to disconnect from Tractus; circulates within the Compact zone (west reach hops 6+). Mostly refused outside Compact territory. Tractus is accepted within the Compact at punitive exchange rates.
|
||||
- **Sol** — Earth legacy currency. Finite pool, no active issuer, no formal exchange rate. Used for crime and untraceable transactions, and as payment for premium Earth luxury imports (wines, foods, exclusive goods). Sol is NOT a currency zone — it is modeled as a shadow economy commodity, not a simulation numeraire.
|
||||
- Commission fines and certification fees are Tractus-denominated (the Commission is Assembly-funded). Compact members paying Commission costs face currency conversion friction — this is a structural driver of the shadow economy in the Compact zone, not a coincidence.

- **~5 professional services** — legal, banking/credit, insurance, logistics management; location-bound (non-transportable through gates)
|
||||
- **~3 luxury/experiential services** — tourism, holo-content/entertainment, cultural experiences; location-bound
|
||||
- Services sit outside the production chain (Raw → Intermediate → Final). Services consume goods but do not produce them.
|
||||
- Each commodity record: tier, elasticity class (5 categories), base price, bulk class, political sensitivity flag.
|
||||
- Each commodity record: tier, elasticity class (4 categories per D-184: perfectly_inelastic, inelastic, unit_elastic, elastic), base price, bulk class, political sub-flags.
|
||||
- Leontief fixed-coefficient production: scarcity in one input cascades to all dependents. No substitution within a tier.
|
||||
- Substitutable inputs at intermediate level: multiple raw sources can satisfy the same intermediate demand (e.g., two ore types producing the same alloy). Substitution is structural (different production chain routes), not smooth.
|
||||
- **Rationale:** Fixed-coefficient production creates legible scarcity cascades — the player can trace why a final good is expensive by following the chain. Services are location-bound by definition (a legal service in Ostmark cannot be freighted to Groenland). The ~30 count is rich enough to generate interesting geographic specialization without becoming intractable to author.

## Rejected Alternatives
|
||||
|
||||
### R-011: Single currency for Phase 2 (rejected)
|
||||
- **Date:** 2026-04-05
|
||||
- **Proposed by:** Burnelli-Sheldon (economist), Sprint 32 Workshop #796 Round 1
|
||||
- **Proposal:** Use a single currency for the Phase 2 economics simulation to reduce model complexity. Exchange rate mechanics could be added in a later phase.
|
||||
- **Rejected because:** Three currencies create structural economic bloc tension as an emergent property of initialization — no event generation required. The Tractus/Mark divide maps directly to the Assembly vs. Compact political divide that is already canonical lore. Deferring currencies to a later phase would require retrofitting political geography into an already-running simulation. The complexity cost of three currencies is low; the design value is high.
|
||||
- **Raised by:** Lead directive overruling the recommendation.

### D-184: Commodity Catalog (36 Types)
|
||||
- **Date:** 2026-04-05
|
||||
- **Decision:** The simulation uses 36 commodity types as the concrete implementation of the taxonomy in D-173:
|
||||
- **9 raw materials** — extracted or harvested, location-bound
|
||||
- **10 intermediate goods** — processed from raws, transportable
|
||||
- **9 final goods** — assembled from intermediates, carry cultural identity
|
||||
- **5 professional services** — legal, banking/credit, insurance, logistics management, data brokerage; location-bound
|
||||
- **3 luxury services** — tourism, holo-content/entertainment, cultural experiences; location-bound
|
||||
- **5 professional services** — legal, financial, medical/re-embodiment, insurance, commission certification; location-bound
|
||||
- **3 luxury services** — tourism, entertainment/holo-content, fine dining/hospitality; location-bound
|
||||
- **Source of truth:** `wiki/economics/commodities.toml` and `wiki/economics/production_chains.toml`
|
||||
- 21 production chains including 2 substitution routes
|
||||
- Schema: 14 fields per commodity including 3 political sub-flags (`politically_sensitive`, `contraband_risk`, `sanctions_applicable`), `production_ubiquity`, `demand_model`, `panic_threshold_weeks`
|
||||
- Schema: 14 fields per commodity including 3 political sub-flags (`commission_certified`, `compact_contested`, `shadow_viable`), `production_ubiquity`, `demand_model`, `panic_threshold_weeks`
|
||||
- **Rationale:** The catalog is the concrete realization of the D-173 taxonomy. 36 types is rich enough to produce meaningful geographic specialization while remaining authorable. The 14-field schema captures economic, political, and behavioral properties needed by the tâtonnement simulation. Two substitution routes prevent hard lock-outs in chains where one raw source is geographically constrained.

||||
- **Raised by:** Full planning team, Sprint 32 Workshop #801.
|
||||
- **Dissent:** None.
