# Module: `problem_deal.pressure_deck`
| | |
|---|---|
| **aspect** | `problem_deal` |
| **module_id** | `problem_deal.pressure_deck` |
| **role** | Small start set + mid-game **Pressure deck** draws |
| **status** | **ready-for-implement** (draft frozen for v0 kernel) |
| **rules_delta** | [`rules_delta.yaml`](rules_delta.yaml) |
| **design** | [history/260808-deal-end-sequences-design.md](../../../history/260808-deal-end-sequences-design.md) |
Independent of end_condition. **Recommended** compose with
`problem_stress.scoped` so drawn scopes matter. Measure alone first if
possible (with default problem_stress.none, influx still adds board clutter).
## Frozen v0 rules
### DEAL-START
- **Always in play at setup:** Surface Problem (priority 0).
- **Also deal face-down:** hidden priority **1** (and priority **2** only if
seats ≥ 4).
- All other scenario Problems for that scenario go into the **Pressure deck**,
shuffled with the game seed (deterministic).
- Seat-band `k` from r0 does **not** bulk-deal the rest; influx replaces
“deal all k at once.”
| seats | starters in play | rest → pressure deck |
|------:|------------------|----------------------|
| 23 | Surface + H1 | H2… |
| 46 | Surface + H1 + H2 | H3… |
### DEAL-INFLUX
At **Round End** (after problem-stress ticks if any, before DARVO arm):
- If Pressure deck non-empty **and** unclaimed Problems in play < **open_cap**,
draw **1** card into play.
- **open_cap** = number of seats.
- Placement: face-down if hidden/personal/bond as printed; Surface-like global
face-up if scope is global.
- Stop drawing for that End once one card is drawn (v0: max 1 per round).
### DEAL-OWN (if problem_stress.scoped also active)
- **personal:** owner = Lead at time of draw (or next free seat clockwise if
Lead already owns ≥2 personal — v0 simplify: **drawer seat = current Lead**).
- **bond:** same owner rule; network = Bond network of owner.
- **global:** no owner.
If `problem_stress.none`, owners may still be recorded for table clarity but
have no stress effect.
### DEAL-POINTS (v0)
- Cards that entered via **Pressure deck draw** have **point_value 0** for
scoring (stress / fiction only).
- **Starters** keep printed `point_value`.
- Scenario **thresholds unchanged** (5/7/9) and apply only to starter claims
+ any printed values that were starters.
This avoids reopening GR-E01 arithmetic while testing influx.
## Non-goals (v0)
- Problems in Solution hand.
- Multiple draws per round.
- Owner-only SOLVE.
- Changing thresholds mid-game.
## Success criteria (when clay-borg implements)
1. Games show mid-game influx (deck depletes or open_cap binds).
2. With scoped stress: variance and DARVO still possible; greedy SHARED 34p
wins not collapsed to H1-zero.
3. Threshold success still well-defined (starter points only).
4. Composable: works with default end_condition and with hybrid end.
