FG-4 Midgame RG-03 And RG-04 Contract

Revision: fg4-midgame-r1 Goal: docs/goals/FG4_MIDGAME_RG03_RG04_GOAL.md Predecessor candidate: 370f2a5 Accepted closure: fe90d6f

Inherited Authority

FG-3 owns the exact closed RG-02 Company, two Records, Save v10, permanent casualty rules and the accepted world-first presentation.
Product economy, battle, save and content authorities remain normative. FG-4 consumes their IDs and formulas instead of copying or renaming them.
The integrated product rule of two Contracts per Region outranks the content catalog's older alternate-boss revisit wording.
Existing profession, trait, equipment, Artifact and enemy identities remain immutable. FG-4 may add executable mappings only for its assigned IDs.

Content Boundary

FG-4 adds exactly:

EQ-081..120, AR-016..022, EN-R3-01..12, BO-R3-01..02 and 72 RG-03 route rows;
EQ-121..160, AR-023..030, EN-R4-01..12, BO-R4-01..02 and 72 RG-04 route rows;
48 deterministic Markets, four fixed Boss Musters, bilingual display authority and one shared FG-4 schema/generator;
production environment, actor, Boss, VFX, music, ambience and semantic SFX bindings for both Regions.

Every Market contains three Recruit slots, four equipment offers and three risk 0/1/2 route offers. Refresh may change Recruit/equipment rows only; route, Region object, clause, Boss and reward facts never reroll.

Region And Contract Structure

RG-03 Emberloom Works

CTR-R3-01 ends at BO-R3-01 Furnace That Walks.
CTR-R3-02 ends at BO-R3-02 Foreman Nine-Sparks.
Every ordinary encounter declares one pressure-valve position and countdown. Occupying, vacating or crossing that index changes the disclosed resolution.
Construct, delayed burst, item cooldown and action-tag repetition are separate mechanics with separate event and counter tags.

Furnace That Walks supports vent-and-brace or strong-side burst plans. Foreman Nine-Sparks supports varied action tags or one deliberately safe promotion followed by focused spark removal. Failure names the exact Pressure or repetition boundary.

RG-04 Quillroot Archive

CTR-R4-01 ends at BO-R4-01 The Walking Index.
CTR-R4-02 ends at BO-R4-02 Redaction Hart.
Every ordinary encounter declares one repeat, alternate or preserve clause, the affected action field and the obey/break result.
Copy, target redirection, cleanse trap and clause evaluation remain separate event families.

The Walking Index supports action-count steering or a timed pointer interrupt. Redaction Hart supports safe seeded rules or reorder-and-interrupt before replay. Failure names the exact label or redacted clause that changed outcome.

Economy And Progression

Line capacity remains at the core cap of ten; FG-4 adds interaction breadth, not another capacity increase.
Ordinary Coin, XP, offer level and price bands use the existing product formulas with Region and Round inputs. A new scalar-growth formula is forbidden.
Bosses grant no spendable Coin.
First-clear Renown is 18/22 for RG-03 Contracts and 20/24 for RG-04 Contracts, using the accepted 8 + 2*G + 4*K formula.
Each Contract writes one Company Record exactly once. RG-03 close unlocks RG-04; RG-04 close unlocks RG-05.

Save And Failure

Save v11 migrates exact Save-v10 region_closed with RG-03 unlocked.
One schema owns every RG-03/RG-04 Market, prepared, recovery, Boss, result, handoff and Region-close phase.
Prepare, battle settlement, recovery, Contract close and Region close are revision-bound and idempotent.
Defeat permanently removes Fallen Recruits, returns equipment, grants bounded Credit, pays no battle Coin and never substitutes Reserve.
Recovery restores the exact Market or Boss Muster without reroll or resurrection.
Active/backup corruption, rollback, duplicate input, interrupted candidate writes and clock change cannot create Coin, XP, Renown, healing, battle ticks, Records or unlocks.

Presentation And Delivery

The canonical FG-2/FG-3 world-first controller is extended through compatible data-driven adapters. A Region-specific card wall, milestone-only simulator or second event authority is forbidden.

The midpoint candidate must show both Region entries, representative ordinary pressure, all four Bosses, loss/recovery, four Records and RG-05 in normal rendering. Paid generation remains inside the current four-call/USD-5 ceiling; raw generated sheets require deterministic processing, import, runtime binding and source-bound review.

Checkpoint 2 includes one runtime-only cached H5 after the immutable local candidate passes. Native packaging, devices, signing, stores and release remain outside this contract.
