===== 1) Design Goal =====
Each action should answer three things at once:
  * Did you succeed right now?
  * Which risk axis did you fail to control?
  * How far in the future does that failure surface?

The system uses two challenge dice as two chosen themes. You may beat one and lose one (weak hit), producing a delayed, themed complication you can prepare for.

===== 2) Dice and Tracks =====
Dice:
  * 1d6 Action Die
  * 2d10 Challenge Dice (CH1, CH2)
  * 1d8 Orbit Die (optional narrative color)

Character stats (assign +1, +1, +2, +2, +3):
  * Survey
  * Breach
  * Process
  * Haul
  * Nerve

Core tracks:
  * Momentum (start +2)
  * Pressure (start 1)
  * Sparks (start 0)
  * Prep by theme (start 0 each)

Pressure penalty to Action Score:
  * Pressure 0-4: 0
  * Pressure 5-7: -1
  * Pressure 8-10: -2

===== 3) Action Themes (Player Chooses Per Action) =====
For every action, the player picks exactly two relevant themes and assigns one challenge die to each.

^ Theme ^ What It Models ^
| Extraction | Rock/ore behavior, tool contact, throughput, yield integrity |
| External | Contracts, law, rivals, market pressure, interception |
| Human | Crew trust, morale, conflict, panic, loyalty |
| Systems | Hull stress, power grid, sensors, reactor, software |
| Void | Environment, debris fields, radiation, anomalies, weirdness |

Example declaration:
  * "I Fracture the Vein with themes Extraction (CH1) and External (CH2)."

This makes every roll explicitly two-dimensional.

===== 4) Orbitfall Roll v2 (Signed Spread Engine) =====
Build Action Score:
  * A = d6 + stat + assets + spent Sparks - Pressure penalty

Roll CH1 and CH2 (d10 each), tied to your chosen themes.

Hit bands:
  * Strong Hit: A > CH1 and A > CH2
  * Weak Hit: A > one challenge die only
  * Miss: A <= CH1 and A <= CH2
  * Ties are not wins

==== Signed Challenge Spread (Detailed) ====
Record signed spreads for both challenge dice:

<code>
S1 = A - CH1
S2 = A - CH2
</code>

Interpretation:
  * Positive spread: you controlled that theme
  * Negative spread: that theme controlled you
  * Magnitude is "distance" from control

On a weak hit, define:
  * W = winning spread magnitude (positive side)
  * L = losing spread magnitude (absolute value of negative side)

Key property:
  * Yes, L can be much larger than W.
  * Example: A=5, CH1=1, CH2=10 -> S1=+4, S2=-5.
  * You succeeded, but your failure on the losing theme is bigger than your success on the winning theme.

This asymmetry drives delayed complications.

===== 5) Queue Generation from Spreads =====
Every weak hit creates one queued complication on the losing theme.

Queue item fields:
  * Theme (the losing challenge die theme)
  * Severity S (from L)
  * Fuse F (from W)
  * Origin CH (the losing challenge die value; used during dampening)
  * Visibility state (how known the effect is before reveal)

==== Severity from Losing Spread (L) ====
^ L (abs loss spread) ^ Severity ^
| 1-2 | S1 Minor |
| 3-4 | S2 Serious |
| 5+ | S3 Severe |

==== Fuse from Winning Spread (W) ====
^ W (win spread) ^ Reveal Turn ^
| 1-2 | Fuse 1 (reveals next turn) |
| 3-5 | Fuse 2 (reveals in two turns) |
| 6+ | Fuse 3 (reveals in three turns) |

Predictability rule (as requested):
  * Smaller challenge spread (small W) -> more immediate and more predictable
  * Larger challenge spread (large W) -> farther reveal and less detail known early

Visibility by fuse:
  * Fuse 1: theme + severity + effect family known now
  * Fuse 2: theme + severity known, exact effect family revealed at Fuse 1
  * Fuse 3: theme known, severity estimate known, effect family hidden until reveal

==== Miss Handling ====
A miss creates two queued items (one per theme) and +1 Pressure now.
For each losing theme i:
  * Severity from Li (same table as above)
  * Fuse from Li:
    * 1-2 -> F1
    * 3-5 -> F2
    * 6+ -> F3

This keeps misses dangerous now while preserving delayed uncertainty.

===== 6) Turn Structure =====
Each turn:
  1. Resolve any queued items already at Fuse 0 (from prior turns).
  2. Take one action (extraction, prep, haul, contract, etc.).
  3. End phase: reduce Fuse by 1 for queued items that existed before this turn.
  4. Items created this turn are //fresh// and do not tick until the next turn.

This cadence means a Fuse 2 warning gives two full future actions to prepare before it resolves.

===== 7) Prep System (Planned Mitigation) =====
Prep is stored by theme:
  * Prep[Extraction], Prep[External], Prep[Human], Prep[Systems], Prep[Void]
  * Max 4 per theme

Prep is spent when a queued event resolves to dampen impact.

==== Prep Actions (gain x Prep on success) ====

=== Forecast Risk (Survey or Nerve) ===
Choose one theme to prepare.
  * Strong Hit: +2 Prep on chosen theme and reveal one hidden effect family
  * Weak Hit: +1 Prep on chosen theme
  * Miss: no Prep, +1 Pressure

=== Harden Operations (Process or Breach) ===
Choose Extraction or Systems.
  * Strong Hit: +2 Prep on chosen theme and -1 Instability
  * Weak Hit: +1 Prep on chosen theme
  * Miss: no Prep, +1 Instability

=== Shape Stakeholders (Nerve or Haul) ===
Choose External or Human.
  * Strong Hit: +2 Prep on chosen theme and -1 Exposure
  * Weak Hit: +1 Prep on chosen theme, then choose +1 Exposure or -1 Momentum
  * Miss: no Prep, +1 Exposure

===== 8) Resolving Queued Events =====
When Fuse reaches 0, resolve each revealed queued item:

1) Optional dampening attempt:
  * Spend 0-3 Prep from the matching theme (consumed)
  * Roll Dampen Score:

<code>
D = d6 + relevant stat + Prep spent - Pressure penalty
</code>

  * Challenge values for dampening:
    * CHa = 4 + current Severity (max 10)
    * CHb = Origin CH (stored when queued)

  * Dampening outcome:
    * Strong Hit: reduce Severity by 2 (minimum 0)
    * Weak Hit: reduce Severity by 1
    * Miss: no reduction and +1 Pressure

2) Apply remaining Severity with fiction-first consequence selection.

===== 9) Consequence Framework (Ironsworn-Inspired) =====
Use //Pay the Price// logic:
  * First choose the consequence that best fits the fiction.
  * If uncertain, roll on the relevant theme table.

Severity budget:
  * S1: apply 1 minor consequence
  * S2: apply 2 minor or 1 major consequence
  * S3: apply 1 major + 1 minor

==== Extraction Consequences ====
Minor:
  * -1 Cargo
  * +1 Instability
  * -1 Quality
  * Next Breach roll -1
Major:
  * -2 Cargo
  * +2 Instability
  * Breach asset disabled until repaired
  * Reserve -1 with no gain

==== External Consequences ====
Minor:
  * +1 Exposure
  * New obligation tag
  * Price haircut (-10 percent on next sale)
  * Rival clock +1
Major:
  * +2 Exposure
  * Forced hostile clause in contract
  * Immediate interdiction scene
  * Lose 1 faction favor

==== Human Consequences ====
Minor:
  * Crew tension +1
  * -1 Momentum
  * +1 Pressure
  * Task handoff delay (lose one action option next turn)
Major:
  * Crew split or refusal scene
  * +2 Pressure
  * Relationship fracture with named NPC

==== Systems Consequences ====
Minor:
  * +1 Pressure
  * Sensor blackout (next Survey -1)
  * Power reroute (cannot use one asset next turn)
  * Minor hull stress (+1 repair cost later)
Major:
  * Asset offline until repair
  * Reactor instability (+2 Pressure)
  * Forced emergency burn (lose 1 Cargo)

==== Void Consequences ====
Minor:
  * +1 Legacy
  * Route drift (+1 travel risk next haul)
  * Strange echo (future event gains +1 Severity)
  * Temporal delay (one queue item does not tick down this turn)
Major:
  * Anomaly incursion scene now
  * +1 Legacy and +1 Instability
  * Environmental lockout (must perform prep before extraction)

===== 10) Example Playthrough (Focus: Spread, Queue, Prep) =====
Prospector: Sera Kade, tug //Pilgrim Finch//.

Start:
  * Pressure 2, Exposure 1, Instability 1
  * Prep all themes at 0

----

==== Turn 1: Fracture the Vein ====
Chosen themes:
  * CH1 -> Extraction
  * CH2 -> External

Roll:
  * A = 5
  * CH1 = 1 (Extraction), CH2 = 10 (External)
  * Spreads: S1=+4, S2=-5 -> Weak Hit

From weak hit spreads:
  * Winning spread W=4 -> Fuse 2
  * Losing spread L=5 -> Severity S3

Queue created:
  * Q1 = [Theme External, Severity 3, Fuse 2, Origin CH 10]

Interpretation:
  * Success now (you got ore), but a severe External consequence is inbound in two turns.

----

==== Turn 2: Prep Action (Shape Stakeholders) ====
Goal: build Prep[External] before Q1 reveals.

Roll result: Strong Hit.
  * Gain +2 Prep[External]
  * Reduce Exposure by 1

Queue tick at start of next turn:
  * Q1 Fuse: 2 -> 1

----

==== Turn 3: Prep Action (Forecast Risk) ====
Goal: add more external prep.

Roll result: Weak Hit.
  * Gain +1 Prep[External]

Prep status:
  * Prep[External] = 3

Queue tick at start of next turn:
  * Q1 Fuse: 1 -> 0 (resolve now)

----

==== Turn 4: Resolve Q1 (Dampen Attempt) ====
Incoming event:
  * Theme External
  * Severity 3
  * Origin CH 10

Spend Prep:
  * Spend 3 Prep[External]

Dampen roll:
  * D = d6(4) + Nerve(2) + Prep(3) - penalty(0) = 9
  * CHa = 4 + Severity = 7
  * CHb = Origin CH = 10
  * 9 beats 7 but not 10 -> Weak Hit

Dampening effect:
  * Severity 3 reduced by 1 -> remaining Severity 2

Apply S2 External consequences (choose fiction-first):
  * Major consequence selected: "Forced hostile clause in contract"

Narrative result:
  * Sera avoids catastrophic seizure of cargo, but signs a predatory exclusivity clause.

This demonstrates the planning loop:
  * detect future risk from spread math
  * spend turns accumulating relevant prep
  * roll to dampen impact at reveal
  * convert remaining severity into theme-consistent consequences

===== 11) Why This Version Works =====
  * Two chosen themes per action make each roll explicit and interpretable.
  * Signed spreads preserve success/failure asymmetry.
  * Winning spread controls time-to-reveal (fuse).
  * Losing spread controls impact size (severity).
  * Prep adds meaningful forward planning instead of pure reaction.
  * Ironsworn-style consequence resolution keeps outcomes fiction-first.

===== 12) Extended Solo Playtest Session: The Black Choir Rock =====
This is a short narrative solo session showing queue timing, prep planning, and fiction-first consequences.

==== Session Seed ====
Sera Kade pilots the //Pilgrim Finch// into a dead freight lane called Hymn Belt-9. Her engineer Juno keeps one hand on the reactor safeties while broker Ilex Vorn pushes contract messages into the cockpit at bad moments.

Rumor: an asteroid known as //Black Choir Rock// contains high-grade osmium and a buried monastic relay core.

Starting state:
  * Pressure 2, Exposure 2, Instability 1
  * Cargo 0, Quality 1, Momentum +2
  * Prep all themes = 0
  * Queue = empty

----

==== Turn 1: Scan the Body (Survey) ====
Themes selected:
  * CH1 -> Extraction
  * CH2 -> Void

Roll:
  * A = 7
  * CH1 = 5, CH2 = 8
  * S1 = +2, S2 = -1 -> Weak Hit

Weak-hit queue outcome:
  * Losing theme Void, L=1 -> Severity S1
  * Winning spread W=2 -> Fuse 1
  * Queue item Q1 = [Void, S1, F1, Origin CH 8]

Move result:
  * Gain 1 Leverage
  * Choose +1 Instability (now 2)

Story:
The scanner paints an ore seam, but the return signal carries a harmonic tone like distant voices. Juno calls it static. Sera does not answer.

End phase:
  * Q1 is fresh; no tick this turn.

----

==== Turn 2: Forecast Risk (Prep for Void) ====
Action result:
  * Strong Hit on Forecast Risk
  * +2 Prep[Void]
  * Reveal hidden effect family on Q1: \"Shard storm in rotating tunnel\"

Story:
Sera runs predictive drift maps and sees why old rigs died here. The tunnel mouth she planned to use is a knife spiral of metallic splinters.

End phase:
  * Q1: F1 -> F0

----

==== Turn 3: Resolve Q1, then Fracture the Vein ====
At turn start, Q1 resolves.

Dampen attempt for Q1:
  * Spend 2 Prep[Void]
  * D = 9 versus CHa=5 and CHb=8 -> Strong Hit
  * Severity 1 reduced to 0 (no consequence applied)

Story:
The storm still comes, but Sera times a lateral burst and rides the dead zone between shard bands.

Now action: //Fracture the Vein// with themes Extraction + External.

Roll:
  * A = 5
  * CH1 = 1 (Extraction), CH2 = 10 (External)
  * S1 = +4, S2 = -5 -> Weak Hit

Queue created:
  * Q2 = [External, S3, F2, Origin CH 10]

Move result:
  * On weak Breach, choose +2 Cargo (now 2)
  * +1 Instability from weak Breach (now 3)

Story:
The cut is perfect. Dense ore breaks free in glittering slabs. A corporate beacon wakes in the dust and tags her claim as \"contested property.\"

End phase:
  * Q2 is fresh; no tick.

----

==== Turn 4: Shape Stakeholders (Prep for External) ====
Action result:
  * Strong Hit on Shape Stakeholders
  * +2 Prep[External]
  * -1 Exposure (2 -> 1)

Story:
Sera opens a narrowcast to Ilex Vorn and trades future margin for immediate legal cover. Ilex buys her exactly one line of deniability.

End phase:
  * Q2: F2 -> F1

----

==== Turn 5: Forecast Risk (More External Prep) ====
Action result:
  * Weak Hit on Forecast Risk
  * +1 Prep[External] (total now 3)

Story:
New traffic appears: patrol cutter //Canticle Needle// and two contract drones. They are not here to negotiate. They are here to inventory.

End phase:
  * Q2: F1 -> F0

----

==== Turn 6: Resolve Q2, then Ride Transfer Window ====
At turn start, Q2 resolves.

Dampen attempt for Q2:
  * Spend 3 Prep[External]
  * D = 9 versus CHa=7 and CHb=10 -> Weak Hit
  * Severity 3 reduced to Severity 2

Apply S2 External consequence (fiction-first):
  * Major: Forced hostile clause
  * Fiction: escrow lock + mandatory inspection corridor

Story:
Sera prevents total seizure of the haul, but signs a predatory transfer clause. Every crate is now visible to the same people hunting her.

Action: //Ride the Transfer Window// with themes External + Systems.

Roll:
  * A = 4
  * CH1 = 6 (External), CH2 = 2 (Systems)
  * S1 = -2, S2 = +2 -> Weak Hit

Queue created:
  * Q3 = [External, S1, F1, Origin CH 6]

Move result:
  * Delivery succeeds on weak hit
  * Choose +1 Exposure (1 -> 2)

Story:
The Finch clears the debris cone, but inspection pings trail her burn. The Canticle marks her wake with jurisdiction tags.

End phase:
  * Q3 is fresh; no tick.

----

==== Turn 7: Emergency Stakeholder Prep ====
Action result:
  * Weak Hit on Shape Stakeholders
  * +1 Prep[External]
  * Choose +1 Exposure (2 -> 3)

Story:
Ilex can suppress one warrant or one rumor, not both. Sera chooses the warrant. The rumor spreads.

End phase:
  * Q3: F1 -> F0

----

==== Turn 8: Resolve Q3, then Close Contract ====
At turn start, Q3 resolves.

Dampen attempt for Q3:
  * Spend 1 Prep[External]
  * D = 5 versus CHa=5 and CHb=6 -> Miss
  * No severity reduction; +1 Pressure (2 -> 3)

Apply S1 External consequence:
  * Minor: Rival clock +1

Story:
The //Canticle Needle// receives an automated bounty ping containing Sera's hull profile and cargo signature.

Final action: //Close the Contract// with themes External + Human.

Roll:
  * A = 8
  * CH1 = 7, CH2 = 5
  * Strong Hit

Outcome:
  * Sale closes at full value under bad terms
  * Sera gains enough credits to keep flying, but exits the belt with a rival hunter on her trail and a hostile clause still attached.

Session-end fiction hook:
Juno asks whether this was worth it. Sera replays the harmonic recording from Black Choir Rock. Under the noise, someone says her name.
