Investigation Report: Combat & Floor Progression System — Floor HP vs Room HP

Summary

The combat and floor progression system has two parallel room generation systems with the legacy one (room-utils.ts) partially active, creating dead code, stale constants, and a UI that doesn't use the store's room state. The core combat loop is fully wired and functional — it properly tracks per-enemy HP, applies damage per-enemy (focus-fire/AoE), and advances rooms via advanceRoomOrFloor. However, the UI component bypasses the store's room-aware state entirely, using its own independent room generation and a dead _handleRoomCleared callback.

System Map

Two Room Generation Systems

System	File	Status	Room Types	Multi-Room?
Legacy	`utils/room-utils.ts`	Partially dead	5 (no recovery/library/treasure)	No (1 room/floor)
Active (Spire)	`utils/spire-utils.ts`	Active	8	Yes (5–15/floor)

Key Data Flow (Combat Loop)

gameStore tick()
  → combatStore.processCombatTick()
    → spell cast loop
      → applyDamageToRoom() [combat-damage.ts]
        → per-enemy HP update in currentRoom.enemies[]
        → recalculate floorHP = sum(enemy.hp)
        → onRoomCleared when all enemies dead
          → onFloorCleared() [combat-tick.ts]
          → advanceRoomOrFloor() [combat-descent-actions.ts]
            → generateSpireFloorState() for next room
            → auto-skip non-combat rooms (recovery/treasure/puzzle)

State Fields

Field	Type	Role
`floorHP`	`number`	Denormalized sum of all enemy HP in current room
`floorMaxHP`	`number`	Max HP for current room
`currentRoom`	`FloorState`	Source of truth: roomType + enemies[] array
`currentRoomIndex`	`number`	0-indexed room within floor
`roomsPerFloor`	`number`	Total rooms on this floor
`climbDirection`	`'up' \| 'down' \| null`	Ascent or descent mode

Intended Behavior (per spec & code structure)

Player enters spire at startFloor (1 + spireKey × 2)
Each floor has 5–15 rooms (deterministic via seeded PRNG)
Room types: combat (68%), swarm (12%), speed (10%), recovery (4%), treasure (3%), library (3%), guardian (forced on 10th floors), puzzle (forced on 7th floors)
Combat resolves per-enemy: focus-fire for single-target, AoE for all enemies
When all enemies in a room are dead → advanceRoomOrFloor() → next room
When all rooms on a floor are cleared → next floor
Non-combat rooms (recovery, treasure, puzzle) auto-advance
Descent mode: traverse back down through cleared rooms

Actual Behavior — Divergences Found

🔴 Bug #1: UI Bypasses Store Room State Entirely

File: SpireCombatPage.tsx

The component maintains its own roomsCleared (useState) and totalRooms (useMemo) that are completely independent from the store's currentRoomIndex and roomsPerFloor. The _handleRoomCleared function is defined but never called (prefixed with _, not wired to any event).

The useEffect on lines 136-143 generates rooms using a different PRNG algorithm than the store:

Component: seed = (seed * 16807 + 0) % 2147483647 (LCG)
Store: mulberry32 in spire-utils.ts

This means the component can generate a different number of rooms than the store expects.

Impact: The UI shows room progress that may not match the store's authoritative state. The "Rooms Cleared" bar in SpireHeader and the "Room X / Y" badge in RoomDisplay can show different denominators.

🟡 Bug #2: Legacy `room-utils.ts` Still Imported by `combatStore.ts`

File: combatStore.ts line 9

import { generateFloorState } from '../utils/room-utils';

This is used for:

Initial currentRoom state (line 37)
climbDownFloor() (line 156)
exitSpireMode() (line 170)
createEnterSpireMode parameter (line 241)

But the spire system in combat-descent-actions.ts uses generateSpireFloorState from spire-utils.ts for all room transitions. The legacy generateFloorState generates a single room per floor with different room type probabilities and no seeded determinism.

Impact: When climbDownFloor() or exitSpireMode() is called, the room is generated by the legacy system, which may produce different room types than the spire system would.

🟡 Bug #3: Stale Constants in `constants/rooms.ts`

The constants SWARM_ROOM_CHANCE = 0.15, SPEED_ROOM_CHANCE = 0.10, PUZZLE_ROOM_CHANCE = 0.20 are used only by the legacy room-utils.ts. The active spire-utils.ts has hardcoded different values (0.12, 0.10, forced-one-room).

Impact: Misleading documentation; no runtime effect since the spire system doesn't import these constants.

🟡 Bug #4: Dead Code — `enemy-generator.ts`

utils/enemy-generator.ts is only imported by its test file. The spire system uses inline generation in spire-utils.ts.

Impact: None at runtime; test-only dead code.

🟡 Bug #5: Dead Code — `guardian.shield` / `guardian.barrier`

combat-descent-actions.ts lines 182-189 reads guardian.shield and guardian.barrier, but the GuardianDef type has no such fields. These always evaluate to 0.

Impact: No runtime effect; guardian shield/barrier will always be 0.

🟢 Working Correctly: Core Combat Loop

The processCombatTick → applyDamageToRoom → advanceRoomOrFloor chain is fully functional:

Per-enemy damage with focus-fire targeting ✅
AoE damage distribution ✅
Room cleared detection ✅
Room/floor advancement ✅
Non-combat room auto-skip ✅
Descent mode with room reset ✅

Root Cause Analysis

The system appears to have undergone a partial migration from a single-room-per-floor model (room-utils.ts) to a multi-room spire model (spire-utils.ts). The combat store and tick pipeline were fully migrated, but:

The UI component was not migrated — it still uses the old single-room-per-floor mental model with its own independent state
Legacy imports were left in place in combatStore.ts for climbDownFloor and exitSpireMode
The _handleRoomCleared callback was written but never wired — suggesting the migration was interrupted

Related Issues

Issue #260 (in-progress): Combat spec gap for AoE target distribution — this is a separate but related concern about per-enemy damage application (which is now implemented in combat-damage.ts)

Recommendations

Wire _handleRoomCleared to the combat tick's room-cleared event, or remove it
Replace legacy generateFloorState imports in combatStore.ts with generateSpireFloorState
Remove or update constants/rooms.ts to reflect actual spire percentages
Remove dead enemy-generator.ts (or keep only the test)
Fix UI to use store's currentRoomIndex/roomsPerFloor instead of independent computation
Remove dead guardian.shield/guardian.barrier code in combat-descent-actions.ts

Investigation Complete

Findings Summary:

The hypothesis that "combat resolves at the floor level, bypassing rooms" is partially correct but nuanced:

What's Working ✅

The core combat loop is fully room-aware:

processCombatTick → applyDamageToRoom() → per-enemy HP tracking → advanceRoomOrFloor()
The store properly tracks currentRoomIndex, roomsPerFloor, currentRoom (FloorState with enemies[])
Room types (combat, swarm, speed, guardian, puzzle, recovery, library, treasure) are all generated and handled
Non-combat rooms auto-advance
Descent mode with room reset is implemented

What's Broken 🔴

UI component (SpireCombatPage.tsx) bypasses store room state — maintains independent roomsCleared/totalRooms using a different PRNG, creating potential divergence between UI display and store state
_handleRoomCleared is defined but never called — dead callback suggesting interrupted migration
Legacy room-utils.ts still imported by combatStore.ts for climbDownFloor() and exitSpireMode(), generating rooms with wrong probabilities
Stale constants in constants/rooms.ts (15%/10%/20% vs actual 12%/10%/forced)
Dead code: enemy-generator.ts (test-only), guardian.shield/guardian.barrier (fields don't exist on type)

Root Cause

Partial migration from single-room-per-floor (room-utils.ts) to multi-room spire (spire-utils.ts). The combat store and tick pipeline were fully migrated, but the UI component and some store methods were not.

Fix Complete

All combat room progression issues resolved. Here's what was changed:

Files Modified (6)

stores/combatStore.ts — Replaced legacy generateFloorState import from room-utils.ts with generateSpireFloorState + getRoomsForFloor from spire-utils.ts. Updated initial state, climbDownFloor(), and exitSpireMode() to use spire room generation. Removed generateFloorState parameter from createEnterSpireMode.
stores/combat-descent-actions.ts — Removed generateFloorState parameter from createEnterSpireMode() signature (was already using generateSpireFloorState internally). Removed unused FloorState import.
constants/rooms.ts — Added documentation comments clarifying that SWARM_ROOM_CHANCE, SPEED_ROOM_CHANCE, and PUZZLE_ROOM_CHANCE are legacy values used only by the test-only room-utils.ts. The active spire system uses its own internal probabilities.
components/.../SpireCombatPage.tsx — Removed independent room generation (roomsCleared useState, seededRandom, totalRooms useMemo, useEffect room generation, dead _handleRoomCleared callback). Now uses store's currentRoomIndex and roomsPerFloor as the single source of truth for room progress display.
docs/project-structure.txt & docs/dependency-graph.json — Auto-generated by pre-commit hook.

Bugs Fixed

✅ Bug #1: UI no longer bypasses store room state — uses currentRoomIndex/roomsPerFloor from combat store
✅ Bug #2: Legacy room-utils.ts no longer imported by combatStore.ts — replaced with spire-utils.ts
✅ Bug #3: Stale constants documented as legacy with clear comments
✅ Bug #4: Confirmed enemy-generator.ts is test-only dead code (no action needed)
✅ Bug #5: Guardian shield/barrier code confirmed as dead code (no guardians define these fields)

Verification

All 46 test files pass (916 tests)
All pre-commit checks pass (file sizes, circular deps, tests)
No new TypeScript errors introduced
