+# Cut 7 (Roles Authored): Operator Review
+
+Generated by `dotnet run --project tools/AetherDb -- roles-migrate` (dry run captures this exact table; `apply`
+landed it in `GameData/Aetheria.cc`). Regenerate with `roles-migrate` any time the catalog changes — this file is
+a snapshot for review, not a second source of truth.
+
+Role vocabulary is small and shared within a kind: the same handful of part names cover every design of that
+kind, not one bespoke name per item. A stat is only pointed at a role when it both carries a `Quality` term and
+actually varies with quality (`Min != Max`) — Cut 1's flat placeholder stats (`Min == Max`, a harmless leftover
+`Heat^1` term) have no observable role-vs-workmanship difference, so pointing a role at one would be authoring
+fiction, not content.
+
+Product role means below are almost all **generic placeholders** (deterministic per product+role, not hand-tuned)
+flagged "needs operator review" — the one exception is Arctica/Alakrita, where `docs/item-provenance-target.md`
+already states a brand identity ("optimizing for heat efficiency"). Every other product is waiting on the
+operator to decide who is actually good at what; right now they only differ from each other by an arbitrary seed,
+not by authored intent.
+
+## Designs and their roles, by item kind
+
+### AetherDrive
+
+| Design | Roles | Stat → role |
+|---|---|---|
+| Traction | coupling, rotor | `AetherDriveData.MaximumRpm` → rotor · `AetherDriveData.Torque` → rotor · `AetherDriveData.CouplingEfficiency` → coupling · `AetherDriveData.EnergyDraw` → coupling · `AetherDriveData.PassiveCoupling` → coupling |
+
+**Role meanings:** *rotor* — the spinning core that produces RPM and torque. *coupling* — how efficiently that
+output couples into drive and how much bleeds off passively.
+
+### CargoBay, ControlModule, DockingBay, Hull/Station, Hull/Turret — no roles
+
+SafeStuff II, Store-All Enterprise Edition, Store-All Plus, Store-All Plus Mini (CargoBay); Cockpit 2x2, Turret
+Control Module (ControlModule); Medium Docking Bay (DockingBay); Zenith (Hull/Station); Turret (Hull/Turret).
+
+**Why:** none of these kinds' behaviours read `StatSource.Quality` at all today (cargo capacity, docking, cockpit
+draw and hull cross-section on these particular designs are flat or non-quality stats) — there is no per-part
+distinction for a role to express yet. Generic quality stays. Turret's own `ReflectorData.CrossSection` is present
+but authored flat (`Heat^1`, no `Quality` term), unlike LonginusX's.
+
+### Hull/Ship
+
+| Design | Roles | Stat → role |
+|---|---|---|
+| LonginusX | plating | `ReflectorData.CrossSection` → plating |
+
+**Role meaning:** *plating* — the hull's armor/stealth coating, which is what actually governs radar cross-section.
+
+### Radiator
+
+| Design | Roles | Stat → role |
+|---|---|---|
+| Arctica | fins, pump, reservoir | `Emissivity`→fins · `WasteHeat`→fins · `PumpedHeat`→pump · `EnergyUsage`→pump · `ThermalMass`→reservoir |
+| cold like my heart | fins, pump, reservoir | same five fields, same roles |
+| OK Disperser | fins, pump, reservoir | same five fields, same roles |
+| Iapyx | reservoir | `ThermalMass`→reservoir only (Emissivity/PumpedHeat/WasteHeat/EnergyUsage are authored flat, `Heat^1`, no Quality term) |
+| Skiron | reservoir | same as Iapyx |
+
+**Role meanings:** *fins* — the radiating surface (emissivity, waste heat). *pump* — the coolant pump (heat moved,
+its own energy cost). *reservoir* — the thermal mass of the coolant loop itself.
+
+### Reactor
+
+| Design | Roles | Stat → role |
+|---|---|---|
+| Core Power | core, regulator | `Efficiency`→core · `OverloadEfficiency`→regulator · `ThrottlingFactor`→regulator (Charge authored flat here) |
+| Manhattan | core, regulator | `Charge`→core · `Efficiency`→core · `OverloadEfficiency`→regulator · `ThrottlingFactor`→regulator |
+| MoveOnPro | core, regulator | same four |
+| Notorious | core, regulator | same four |
+| Vulcan | core, regulator | same four |
+
+**Role meanings:** *core* — the primary reaction chamber (raw charge and efficiency). *regulator* — the safety and
+throttling electronics (overload behaviour, throttling).
+
+MoveOnPro also carries a `StatModifierData.Modifier` (Quality-termed) — left at generic quality: it modifies an
+external stat rather than the reactor's own part, so no reactor role fits it.
+
+### Sensors
+
+| Design | Roles | Stat → role |
+|---|---|---|
+| not if i see you first | emitter, receiver | `Sensitivity`→receiver · `PingBoost`,`PingEnergy`,`PingVisibility`,`PingRange`,`PingCooldown`→emitter |
+| The Bat | emitter, receiver | `Sensitivity`→receiver · `PingBoost`,`PingVisibility`,`PingRange`,`PingCooldown`→emitter (`PingEnergy` authored flat here) |
+| Tractor Beam | *(none)* | dead design (S1, Cut 1 findings): every field is flat, nothing to point |
+
+**Role meanings:** *receiver* — passive sensitivity. *emitter* — the active ping subsystem (boost, cost,
+visibility, range, cooldown).
+
+### Thruster
+
+| Design | Roles | Stat → role |
+|---|---|---|
+| deep space burnout | injector, nozzle | `Thrust`→nozzle · `Visibility`→nozzle · `Heat`→injector (`EnergyUsage` authored flat 0/0, no terms) |
+| Large Drive | *(none)* | every field authored flat (`Heat^1`/`Quality^1` but `Min == Max` throughout) |
+
+**Role meanings:** *nozzle* — exhaust output and plume (thrust, visibility). *injector* — fuel/power feed, whose
+byproduct is heat.
+
+### Tool
+
+Tool is not a shared kind the way a laser or radiator is — each design is its own bespoke gadget, so roles are
+authored per design rather than from one shared field map.
+
+| Design | Roles | Stat → role |
+|---|---|---|
+| Industrial Thermostatic Heater | heating element | `EnergyDrawData.EnergyDraw`→heating element · `HeatData.Heat`→heating element |
+| PotaT+- | converter, storage cell | `CapacitorData.Capacity`→storage cell · `CapacitorData.Efficiency`→converter |
+| Assembly Line, Deep Ore Extractor, Refinery, Shipyard, Surface Ore Extractor | *(none)* | carry no `PerformanceStat` behaviour at all in the current catalog |
+
+### Weapon/Ballistic
+
+| Design | Roles | Stat → role |
+|---|---|---|
+| 6k Shooter | barrel, feed mechanism | `Damage`,`Range`,`Velocity`→barrel · `Heat`,`Visibility`,`Spread`→feed mechanism |
+| Earp | barrel, feed mechanism | same shape as 6k Shooter |
+| ClearPath | barrel, feed mechanism | `Damage`,`Range`,`Velocity`→barrel · `Cooldown`,`Energy`,`Heat`,`Visibility`,`Spread`→feed mechanism |
+| DeathCluster | barrel, feed mechanism | same shape as ClearPath |
+| pretty pretty bang bang | barrel, feed mechanism | same shape as ClearPath (charged weapon, same field names) |
+| Autocannon | *(none)* | dead design (S1, Cut 1 findings): every field flat |
+
+**Role meanings:** *barrel* — the part that decides damage, range and muzzle velocity. *feed mechanism* — cycling:
+rate of fire, spread, heat and signature it generates, and (where authored) its energy cost.
+
+### Weapon/Energy
+
+| Design | Roles | Stat → role |
+|---|---|---|
+| CShot RainbowLite Lazer | focusing array, power coupling | `Damage`,`Range`→focusing array · `Cooldown`,`Energy`,`Heat`,`Visibility`,`Spread`→power coupling |
+| ColdFire | focusing array, power coupling | same shape |
+| Spectra | focusing array, power coupling | same shape |
+| FastBlast+- | focusing array, power coupling | `Damage`,`Range`,`Velocity`→focusing array · `Cooldown`,`Heat`,`Visibility`,`Spread`→power coupling |
+| ChargeBlast SG | focusing array, power coupling | `Damage`,`Range`,`Velocity`→focusing array · `ChargeTime`,`ChargeHeat`,`Cooldown`,`Visibility`,`Spread`→power coupling |
+| ChargeBlast+- | focusing array, power coupling | same shape as ChargeBlast SG |
+| plight | focusing array, power coupling | `Damage`,`Range`→focusing array · `ChargeTime`,`ChargeEnergy`,`ChargeHeat`,`Cooldown`,`Heat`,`Visibility`→power coupling |
+
+**Role meanings:** *focusing array* — the beam optics that decide damage, range and velocity. *power coupling* —
+everything about how the weapon draws, stores and discharges energy (including charge-up on charged lasers) and
+the heat/signature that produces.
+
+### Weapon/Launcher
+
+| Design | Roles | Stat → role |
+|---|---|---|
+| GT 3K | guidance system, thruster, warhead | `Damage`,`DamageSpread`→warhead · `LockSpeed`,`SensorImpact`,`LockAngle`,`DirectionImpact`,`Decay`,`Range`,`Cooldown`,`Energy`,`Heat`,`Visibility`→guidance system · `Thrust`,`MissileVelocity`,`Velocity`→thruster |
+| pswarm | guidance system, thruster, warhead | `Damage`,`DamageSpread`→warhead · `Cooldown`,`Range`,`Energy`,`Heat`,`Visibility`→guidance system · `Thrust`,`MissileVelocity`,`Velocity`→thruster |
+| scorched void policy | guidance system, thruster, warhead | same shape as pswarm |
+| LRMM72, SRMM72 | *(none)* | dumbfire volleys authored fully flat: every field `Heat^1`, nothing varies |
+
+**Role meanings:** *warhead* — payload (damage, damage spread, penetration). *guidance system* — the seeker
+(lock speed/angle, sensor and direction sensitivity, decay, targeting range, cooldown, its own energy/heat/
+signature). *thruster* — the missile's own motor (thrust, flight/missile velocity).
+
+## Product role quality authored
+
+37 products exist; 28 got role-quality entries this pass (the rest sell a design that authored no role, or are
+one of the two-missile launchers left flat). All means/deviations are **generic placeholders** except Arctica's
+`fins`, and every row below needs an operator pass to become real brand identity rather than an arbitrary seed.
+
+| Product (= design; content pass to split brand vs. design names is separate scope) | Role | Mean | Dev | Basis |

+
+**Not authored (no product sells the design, so nothing to author):** Core Power, Industrial Thermostatic Heater,
+pswarm, plight (all previously flagged "no product sells" in the Cut 1 census; still true here).
+
+## O7 — what the operator should actually do with this
+
+Everything above the "generic — needs review" line is mechanically correct (verified: `census`'s new
+"(product, role) pairs where a sold, role-bearing design authors no matching spread" check reports 0, and two
+products of one design with different means resolve a role-termed stat to different, deterministic values —
+`RoleAuthoringTests.TwoProductsOfOneDesignWithDifferentRoleMeansResolveDifferentValues`). What it is *not* is
+real market segmentation: every design still has exactly one product, so nothing yet demonstrates "a second
+product with a role pumped up." That is next scope, and it needs the operator's judgment on which manufacturer
+is good at what — this table is the jumping-off point, not the destination.
