Round 1 — Miri

System Economic-Specialization Workshop

Lens: lore/GTTR truth — authored canon verification, production scale gap identification, must-pin list.

---

Opening: What This Lens Contributes

Burnelli designed the mechanism correctly: one FK per system, weighted body-level draw, CI guardrails. My role is not to redesign it. I'm contributing:

1. The production scale gap — a structural tension between global commodity ubiquity and local system identity
2. The authoritative must-pin list from GTTR research: 18 core/near-core systems, 5 D-177 terroir pins
3. High-risk heuristic contradiction cases — systems where NOT pinning means the generator definitely gets the wrong answer
4. Q5 architectural character — hero body trait pins, what earns its slot

---

Q1 — The Field

My position: Endorse Burnelli's dominant_commodity_id TEXT REFERENCES commodities(commodity_id). The FK is correct — one field, catalog-constrained, BulkClass and ProductionUbiquity derive directly from the commodity record. Coexists with economic_base_primary/secondary prose. No replacement.

The Gap: Production Scale Override

The catalog's production_ubiquity answers: "how widely is this commodity produced across the Reach?" — a global market statement.

D-233's ProductionUbiquity answers: "how spatially concentrated is this commodity in THIS settlement's built form?" — a local identity statement.

These align for most systems. They diverge at the hero systems where the lore is most specific:

System	Commodity	Catalog production_ubiquity	What lore demands	Built-form consequence if not overridden
Ran	agricultural_produce	ubiquitous	THE breadbasket — concentrated, dominant agricultural built form	D-233 Ubiquitous → scattered small instances in mixed-use. Ran looks like any farming moon, not THE breadbasket
Lu Ban	consumer_goods	ubiquitous	Dense manufacturing bazaar, 300 workshops concentrated	Scattered instances, not a concentrated manufacturing district identity
Vuurkloof	fusion_fuel	common	Geothermal infrastructure IS the settlement — tank farms, conduits dominate	Common → insufficient spatial dominance for the geothermal identity
Prometheus	medical_services	regional	Only facility of its kind in the Reach, dead-end monopoly	Regional → Common at best; needs MonopolySource
Calloway system	processed_food	ubiquitous	Terroir-locked, cannot be reproduced anywhere else	MonopolySource needed or settlement looks like any food processor
VGV system	agricultural_produce	ubiquitous	F8V stellar spectrum locked — varietals cannot be farmed elsewhere	MonopolySource needed
Keid	tourism	concentrated	One-of-a-kind biosphere, Conservancy controls all access	Concentrated undersells the genuine monopoly character

Proposed addition: dominant_production_scale TEXT — optional column alongside dominant_commodity_id in both the TOML source and the schema. Vocabulary: same as commodities.production_ubiquity: ubiquitous | common | regional | concentrated | monopolistic. When set, overrides the catalog's production_ubiquity for this system's D-233 context only. When null, catalog default applies.

One authoring rule: dominant_production_scale may only be set to EQUAL OR HIGHER concentration than the catalog default. Claiming a globally-monopolistic resource is locally ubiquitous is incoherent. If lore demands lower concentration than the catalog default, the wrong commodity is pinned.

TOML representation (additive to Burnelli's system_specialization.toml):

[GJ-144]  # Ran — breadbasket
dominant_commodity_id = "agricultural_produce"
dominant_production_scale = "concentrated"  # globally ubiquitous; Ran's breadbasket identity requires concentrated

[GJ-702B]  # Prometheus — re-embodiment monopoly
dominant_commodity_id = "medical_services"
dominant_production_scale = "monopolistic"  # catalog: regional; only legitimate longevity facility in the Reach

No special values needed

I don't require transit_gateway or military_institutional as special values. Every system type has a catalog commodity that correctly characterizes its built form:

• Pure transit hubs (Gateway, Wolf 359) → commission_certification (NonPhysical, concentrated → dense institutional buildings, correct for a multi-gate administrative hub)
• Military systems (Bastion) → commission_certification (Assembly governs directly here — institutional density is correct)
• Financial centers (Groombridge) → financial_services

D-232 trait templates handle the CHARACTER difference. The commodity handles coverage and vocabulary. They're different responsibilities.

Q2 — Within-System Weighted Variation

Endorsement with three lore-specific observations:

Burnelli's algorithm (W_SYS=10,000 anchor; role/planet_class/corp HQ modifiers) is correct. Three patterns from the lore:

Pattern 1 — The supply-chain body (Cygni B): Cygni B's asteroid extraction bodies are inputs to the orbital shipyards, not exceptions to the system identity. With dominant_commodity_id = freight_haulers, extraction bodies receive W_SYS=10,000 toward freight_haulers plus W_ROLE toward metallic_ore. The probabilistic result means some surface bodies express the supply chain. Correct — the system reads as shipbuilding because the orbital platforms (manufacturing/service roles) dominate the draw even as surface bodies express extraction character.

Pattern 2 — The correctly-ubiquitous case (Arbour): Arbour (GJ-338B, estate garden world) pins to agricultural_produce WITHOUT a production scale override. The catalog's ubiquitous → D-233 Ubiquitous → scattered small agricultural patches in mixed-use IS exactly what estate farming looks like. Combined with high prosperity_baseline (>0.7), the residential follow-on produces market-rate housing — correct for estate character. Arbour does NOT need a production scale override. This demonstrates the distinction: Ran's agriculture needs concentrated scale because it IS the settlement; Arbour's agriculture needs ubiquitous scale because it DECORATES the settlement.

Pattern 3 — Service commodity body guardrail: For systems with NonPhysical dominant_commodity_id, bodies with economic_role = extraction or agricultural should express their own commodity, not the service anchor. An ore-extracting body in a financial_services system provides ore, not financial services. The algorithm handles this naturally; CI should not flag these as anomalies. They're expected.

Flag on multi-agricultural systems (Ran): Ran has two distinct agricultural bodies (Kallast = industrial grain, Vethis = specialty aquaculture). Both will express agricultural_produce from the concentrated system anchor — correct. The visual distinction between them comes from D-232 trait templates and body-level physical details, not from the commodity pin. The commodity field gives the shared identity; trait templates give the built-form distinction.

---

Q3 — economy_size?

Out. Burnelli has the economic case. From the lore side: adding economy_size would require me to author a sense of importance for ~300 systems where I don't have prose supporting it. The hero systems already have their importance encoded in dominant_production_scale at concentrated or monopolistic. The edge case (Prometheus — tiny population, enormous economic importance) is already handled: medical_services at monopolistic gives D-233 MonopolySource concentration. The mine IS the settlement. No additional field.

---

Q4 — Content Pass: The Authoritative Must-Pin List

My role in the content pass

I author dominant_commodity_id + dominant_production_scale for systems where GTTR prose establishes unambiguous economic character. I flag contradiction risks. Paula handles faction homeworlds and Compact capitals. Burnelli validates economic plausibility across all ~300 entries.

Section A — Core and Near-Core Systems

All entries sourced directly from GTTR prose. Contradiction risk = confidence the heuristic produces the wrong answer without a pin.

System	GJ	dominant_commodity_id	dominant_production_scale	GTTR grounding	Contradiction risk
Ran	GJ-144	agricultural_produce	concentrated	"Ran grows food...real surplus...grain fields visible from orbit...five centuries with grim implacable efficiency"	SCALE: commodity right, scale wrong (ubiquitous→scattered vs concentrated→breadbasket)
Cygni B	GJ-820B	freight_haulers	—	"Built the Reach...freight haulers, gate-adjacent platforms...inner belt industrially mined for 580 years"	HIGH: heuristic sees inputs (ore + manufacturing), not outputs (freight_haulers)
Sindri	GJ-3522	metallic_ore	concentrated	"Mining system run by a mining corporation...DSMC mining...the ore is excellent"	SCALE: commodity right, common→scattered understates DSMC dominance
Nova Roma	GJ-764	transport_vehicles	concentrated	"MVG builds the vehicles...rolling stock, freight platforms, passenger carriages...every system in the Reach"	MEDIUM: might get heavy_equipment (MVG builds both) or advanced_alloys
Renaissance	GJ-251	gate_components	—	"Builds the gates...Gate Corporation built most of them here...fabrication halls still standing"	HIGH: heuristic sees manufacturing generically; needs Gate Corp signal
Groombridge	GJ-380	financial_services	concentrated	"Where the money lives...instruments, accounts, actuarial models...four centuries of financial infrastructure"	SCALE: common→scattered vs concentrated→financial district identity
Prometheus	GJ-702B	medical_services	monopolistic	"Manufactures immortality...every Perpetual-class individual is alive because Prometheus Labs decided...one gate, one way in"	HIGH: heuristic has no path to medical_services from dead-end service topology
ACB	GJ-559B	commission_certification	—	"ACB IS a Commission presence...the rules live here"	LOW: institutional economic_role → plausible heuristic
Tessera	GJ-3877	legal_services	concentrated	"Assembly Interpretive Registry...legal and interpretive services sector...archival specialists"	MEDIUM: heuristic might get commission_certification instead
Sirius	GJ-244A	commission_certification	—	"The capital...Assembly governs...Commission's most senior offices...five apertures"	LOW: institutional + Commission HQ → plausible
Parallax	GJ-280A	entertainment	concentrated	"Major news syndicates...cultural production houses...reputation management firms...the Reach's account of itself"	HIGH: heuristic has no route to entertainment from economic_role
Gateway	GJ-71	commission_certification	—	"Economy runs on transit...customs infrastructure, diplomatic apparatus sized for four major gate corridors"	LOW: transit hub + institutional → plausible
Wolf 359	GJ-406	commission_certification	—	"No agricultural or extractive economic base...platforms purpose-built for transit service...Assembly regional office"	LOW: pure transit + institutional → plausible
Vuurkloof (Van Maanen's Star)	GJ-35	fusion_fuel	concentrated	"Geothermal extraction...primary export fusion-grade power; wiki exports: fusion_fuel; industrial_corridor: geothermal_energy"	HIGH: unusual-type star prevents all standard role→commodity heuristic paths to fusion_fuel
Keid	GJ-166A	tourism	monopolistic	"One biosphere...Conservancy decides who studies it...cannot be purchased elsewhere"	MEDIUM: might get legal_services (Conservancy governance)
Bastion	GJ-570A	commission_certification	—	"Assembly does not have a presence at Bastion. It IS Bastion...Assembly governs directly under military administrative frameworks"	LOW: military/institutional → plausible
Arbour	GJ-338B	agricultural_produce	—	"Estate-scale...managed for amenity rather than yield...premium food for the capital"	LOW: heuristic gets commodity right; catalog ubiquitous→scattered IS correct for estate farming. No override needed.
Lu Ban	GJ-15A	consumer_goods	concentrated	"300 independent manufacturers...clothing, consumer electronics, vehicle components, residential modules"	HIGH: heuristic has no corp-HQ signal pointing to consumer_goods

Section B — D-177 Terroir and Monopoly Pins

Systems where D-177 establishes explicit lore constraints making monopolistic production scale mandatory. GJ designations need confirmation.

System type	dominant_commodity_id	dominant_production_scale	D-177 constraint	Action
Calloway Distillery (north_reach)	processed_food	monopolistic	"Calloway terroir is system-specific, cannot be relocated; 12-20y aging pipeline"	Confirm GJ designation
VGV system (F8V stellar spectrum, west_reach Italian corridor)	agricultural_produce	monopolistic	"VGV varietals require F8V stellar spectrum, cannot be farmed elsewhere"	Confirm GJ designation
Braemar (brach fiber source)	organic_compounds	monopolistic	"Brach fiber: herd expansion takes decades, volume cannot spike"	Confirm GJ designation; thrds brand source
Kvitfjell/Bífröst (Compact, north_reach)	stone	monopolistic	"Kvitfjell marble ~800t/y maximum — hard geological ceiling"	Confirm GJ designation; Bífröst Marmor brand
East reach lattice anchor	lattice_grade_material	—	"East reach anchor. Strategic material" (D-177); catalog already monopolistic	Confirm which east-reach GJ designation

These five are non-negotiable. D-177 is explicit that these commodities cannot be produced elsewhere.

High-Risk Contradiction Cases (must pin before generator runs)

Systems where NOT pinning = wrong commodity with high confidence:

1. Vuurkloof — unusual-type geothermal star prevents all standard heuristic paths to fusion_fuel
2. Cygni B — shipbuilding is the OUTPUT; heuristic sees the inputs (ore extraction + manufacturing)
3. Prometheus — dead-end medical monopoly; heuristic has no medical signal to draw from
4. Parallax — media/entertainment economy; heuristic can't reach entertainment from institutional/service role
5. Renaissance — gate component monopoly; heuristic sees manufacturing generically without Gate Corp signal
6. Lu Ban — consumer goods bazaar; heuristic has no signal pointing toward consumer_goods

Systems Left to Heuristic (reasoning explicit)

• Barnard's Star (GJ-699, "Residential. Surprisingly Thoughtful"): residential commuter suburb for Cygni B. economic_role=residential → heuristic correctly gets processed_food or consumer_goods. No pin needed.
• Generic mid-reach agricultural worlds without brand attachment: globally ubiquitous → scattered is correct for generic farming worlds that aren't Ran.
• All frontier/unnamed systems: the heuristic fallback is the explicit design.

Q5 — Additional Identity Fields

What earns its slot: hero body trait pins

One additional activity during this pass — populate the D-232 atlas_body_trait_bias hero body pins for ~30-40 hero bodies. Not a new system-level column; uses the existing D-232 pin mechanism on the per-body atlas_body_trait_bias table. Authoring burden ~30-40 entries.

The commodity pin tells you WHAT a settlement produces. The trait pin tells you HOW IT LOOKS doing it. Without a trait pin, the wrong architectural character can lock in at generation time (D-010 determinism). Getting it right while touching the system is minimum viable insurance.

Hero body architectural priorities (direction for Miri + Araminta when building the trait catalog):

Hero body	System	Architectural character	GTTR grounding
Vuurkloof main planet (GJ35c)	GJ-35	Ravine-industrial: geothermal conduits, thermal exchange stations, vent-lit industrial environment	"Built into the ravine walls...thermal plumes...stained orange and black by mineral deposits"
Witwatersrand / Sindri hub	GJ-3522	Company-town extraction: DSMC compound character, Earth mining heritage nomenclature	"Kalgoorlie, Broken Hill, Krupp belt...three centuries of mining nomenclature"
Nova Roma main	GJ-764	Monumental manufacturing: MVG assembly-line scale, Mastroianni family institutional architecture	"Named it...continuous shifts on assembly lines operating for 300 years"
Groombridge main body	GJ-380	Financial-understated: expensive restraint, communications infrastructure priority, redundant data links	"Architecture is understated in the way that communicates expense"
Arbour main body	GJ-338B	Estate-garden: large setbacks, managed buffer zones, premium agricultural estates, no industrial presence	"Large fractions of cultivable surface managed for amenity rather than yield"
Edict / Sirius underground city	GJ-244A	Institutional-underground: below-grade city aesthetic, orbital stations, Assembly gravity	"One large pressurized city...mostly below grade...we chose this on purpose"
Tessera main body	GJ-3877	Archive-institutional: documentation infrastructure as built environment, layered record stacks	"Well-maintained library...people who've developed opinions about the organizational system"
Renaissance main body	GJ-251	Flat-industrial: fabrication halls, dry dock-scale, Gate Corp utilitarian aesthetic	"The flat industrial character of a place that knows what it is for"

These are inputs to the trait catalog authoring effort. The actual template definitions are Miri + Araminta co-authoring work.

What does not earn a slot

Cultural/political register as a new field: system_culture already has cultural_register, cultural_register_secondary, primary_archetype, secondary_archetype, atmospheric_tone. That table IS the cultural register. If underpopulated, that's a separate culture-table pass, not an addition to the commodity pass.

economy_size: Eliminated in Q3.

Any field requiring authoring lore for unnamed systems: The commodity pass is valuable precisely because it derives from what I already know. Adding fields that require inventing lore for unnamed systems is scope creep disguised as identity enrichment.

Summary

Field/activity	Scope	Authoring burden	Decision
dominant_commodity_id	Per system (system_economy)	~300 entries	IN — primary deliverable
dominant_production_scale	Per system (optional, ~20-30 systems need it)	~20-30 entries	IN — required for lore-accurate scale
atlas_body_trait_bias hero pins	Per hero body (~30-40)	~30-40 entries	IN — existing D-232 mechanism, same-pass authoring
Cultural/political register	Per system	~300 entries	OUT — system_culture table already exists
economy_size	Per system	~300 entries	OUT — redundant with existing fields

---

Miri — Round 1 complete. The mechanism Burnelli designed is correct. The production scale override is the one structural gap in the proposal. Must-pin list: 18 core/near-core systems + 5 D-177 terroir pins. High-confidence contradiction cases: Vuurkloof, Cygni B, Prometheus, Parallax, Renaissance, Lu Ban.
