Engine API surface changes + +### Added to `IEngine` +| Function | Purpose | +|---|---| +| `addEffectIfNotPresent(targetIndex, monIndex, effect, extraData) → bool added` | Coalesces the "iterate `getEffects` to dedup, then `addEffect`" idiom that 17 abilities used. Internal storage-side scan. Returns `true` if newly added; `false` if a live slot already held this effect. | +| `executeBatchedTurns(battleKey, entries) → (uint64 executed, address winner)` | Drains N buffered turns in a single tx. Used by `SignedCommitManager` (PvP buffered) and `BatchedCPUMoveManager` (CPU). Amortizes per-turn cold-storage access. | +| `getStorageKey(battleKey) → bytes32` | Resolves a `battleKey` to the storage key used by `BattleConfig` slot allocation. Managers key their own buffers by storageKey so slot reuse across battles via `MappingAllocator` benefits from warm-SSTORE costs. Returns `battleKey` itself if no allocation recorded. | +| `getSubmitContext(battleKey) → (address p0, address p1, uint64 turnId, uint8 winnerIndex, bytes32 storageKey)` | Minimal context for async-submit-then-batch-execute flow. 1 STATICCALL + 3 SLOADs instead of the `getCommitContext` + `getStorageKey` pair (2 calls + 5 SLOADs). | + +### Added to concrete `Engine` only (not in `IEngine`) +| Function | Purpose | +|---|---| +| `executeWithDualSignedMovesDirect(...)` | Opt-in direct-execute path for battles started with `moveManager == address(0)`. Verifies the EIP-712 revealer signature inline + executes, bypassing the `SignedCommitManager` STATICCALL. Saves ~3k/turn versus the manager-routed flow. Domain: `("Engine","1")`, distinct from manager domain. | + +### Removed from `IEngine` (and `Engine`) +| Function | Reason | +|---|---| +| `getMoveManager(bytes32)` | Zero callers anywhere in `src/`. Pure dead weight. | +| `getBattleValidator(bytes32)` | Zero callers anywhere. Validator already surfaced in `BattleContext` / `ValidationContext` / `CPUContext`. | +| `getMonStateForStorageKey(storageKey, …)` | Test-only. All 4 callsites passed `battleKey` and were equivalent to `getMonStateForBattle`. Tests migrated. | +| `getPrevPlayerSwitchForTurnFlagForBattleState(battleKey)` | Test-only (1 callsite). Replaced with `getBattle()` destructure pulling `prevPlayerSwitchForTurnFlag` off `BattleData`. | + +### Net surface delta +- **+4 functions** added, **-4 functions** removed. +- Dispatch table is the same size as baseline, but the kept surface is more focused. + +### Tried and reverted +| Function | Reason for removal | +|---|---| +| `getMoveContext(battleKey, atkP, atkM, defP, defM) → MoveContext` | Fat batched getter that returned both sides' stats + state + effect arrays. Pays for SLOADs + memory allocation + ABI encoding of unused fields. Only SneakAttack used ≥10 of the returned fields (net win ~13k/call); every other tested candidate (HoneyBribe, NightTerrors, HardReset) regressed by 4-97k. Maintaining a one-consumer API didn't pencil out — reverted SneakAttack to individual getters too. | +| `getAndInitGlobalKV(key, valueIfZero) → uint192 previous` | "Atomic read + init-if-zero" combined call. Audit of the 9 `globalKV` consumer sites found only 1 migratable site (RiseFromTheGrave) — others are read-modify-write counters or conditional-set-after-work that don't fold into eager-init semantics. | + +--- + +## 2.

Holds committer preimage (`msg.sender` proves identity) + revealer preimage + revealer EIP-712 signature. Single-sig flow: committer signature implicit in `msg.sender == committer` check at submission time. + +--- + +## 3. New managers / execution modes + +### `BatchedCPUMoveManager` (`src/cpu/BatchedCPUMoveManager.sol`) — NEW +Single-player CPU batched mode. The player computes the CPU's move off-chain (via the Solidity-to-TypeScript transpiler), submits `(playerMove, cpuMove)` tuples to an on-chain buffer, and drains the buffer with one `executeBatchedTurns` call. + +**Why this works:** there's no counterparty to cheat. Misrepresenting the CPU's response just gives the player a worse experience. Eliminates per-submit `ICPU.calculateMove` STATICCALL, `CPUContext` calldata, salt derivation, and per-turn event. + +Per-submit cost: roughly **1 × SLOAD + 2 × SSTORE**. + +Storage layout — all keyed by `storageKey` (benefits from `MappingAllocator` reuse): +- `moveBuffer[storageKey][turnId]` — packed (p0Move, p1Move) tuple per turn, interchangeable with `SignedCommitManager.moveBuffer`. +- `bufferState[storageKey]` — combined slot: `numExecuted` (31b) | `gameOverFlag` (1b) | `numBuffered` (32b) | `lastSubmitTs` (32b) | `p0` (160b). +- `storageKeyOf[battleKey]` — cache to avoid `getStorageKey` STATICCALL on subsequent submits. + +Cache hits after first submit: single SLOAD of `bufferState` gives p0, gameOver, counters — no engine STATICCALL needed. + +### `SignedCommitManager` — buffered submission added +New entrypoint: `submitTurnMoves(battleKey, TurnSubmission entry)` writes to the buffer; `executeBuffered(battleKey)` drains via `executeBatchedTurns`. + +Trust model: committer's identity is `msg.sender` (no committer sig needed). Revealer signs `DualSignedReveal{committerMoveHash, revealerMoveIndex, revealerSalt, revealerExtraData, battleKey, turnId}` off-chain; committer carries the sig into their submission. + +Switch turns use the same shape — non-acting player signs a `NO_OP` (move 126); engine ignores their half at batch time using the live `playerSwitchForTurnFlag`. + +Per-batch execute: `executeBuffered` reads all currently buffered entries, runs them sequentially with engine state held in **transient shadow storage** (see §4), flushes once at the end. + +### Direct dual-signed entry on `Engine` +`executeWithDualSignedMovesDirect(...)`: opt-in via `moveManager == address(0)` at battle start. Does its own EIP-712 sig verification + auth + executes. Saves the `SignedCommitManager` STATICCALL on the per-turn legacy path. + +Measured: B=14 turns via manager 1,741,827 vs via engine direct 1,696,946 (-44,881 total, ~3.2k/turn). + +**Caveat:** stall-timeout via `Engine.end()` for `moveManager==0` battles requires a validator or hitting `MAX_BATTLE_DURATION`. No manager-mediated timeout path. + +--- + +## 4.

Lessons worth keeping (things tried + reverted) + +| Experiment | Result | Lesson | +|---|---|---| +| **Fat batched-getter `getMoveContext`** | Saved 13-16k per SneakAttack call (uses 10+ fields). Regressed every other tested site by 4-97k (use 3-4 fields). | Fat getters only pay when callers use **most** returned fields. Hidden costs: SLOADs for unused state, effect-array iteration + allocation, struct ABI encoding (~1.1kb). Lean point-getters or compact context structs (like `DamageCalcContext`) win for partial-use. | +| **Tiered `EffectInstance` storage (inline data when fits)** | Slot-0 inline data when `< 96 bits` to save the slot-1 SLOAD. Net loss after dispatch overhead. | Per-slot tiered branching often costs more than the SLOAD it tries to skip, especially when the hot side already amortizes. | +| **Yul switch for tiered effect dispatch** | Cleaner generated code but still net-negative once dispatch table is paid. | Confirmed the tiered-storage idea isn't worth it from a different angle. | +| **First transient shadow attempt (`3aa1026`)** | Did not save gas at the time — slot-1 still being read field-by-field, shadowing the whole struct cost more than it saved. Re-landed later (`e2616dd`, `55f2929`) after the slot-1 read-coalescing prerequisite was in. | Optimizations have ordering dependencies. Cache layers help only when the cached values would otherwise be reloaded. | +| **Salt size reduction (104 → 96 bits) + epoch tag** | Pulled — broke EIP-712 sig format and the savings were marginal. | Don't change wire formats for small wins. | +| **`_handleEffectsTriple` cross-branch hoist** | Pulled — broke `HardReset`'s conditional-dedup data check by reordering effect dispatch. | Effect lifecycle is more tightly ordered than it looks; speculative hoists need per-mon test coverage. | +| **`getAndInitGlobalKV`** | Built it expecting ~5 adoption sites; audit found 1. Removed cleanly. | Audit candidate sites against the actual API semantics before adding the API. Read-modify-write counters don't fit eager-init flag semantics. | + +--- + +## 8.

This document records what shipped, what was tried and +rejected, what was deferred, and the measured savings. -Amortize per-turn cold-storage access in `Engine.execute()` by: -1. Submitting each turn's signed moves on-chain immediately to a per-turn buffer (no execute). -2.

For surviving public API see `IEngine.sol`. --- -## 2. Mechanism - -### 2.1 Per-turn submission (PvP) - -`SignedCommitManager.submitTurnMoves(battleKey, TurnSubmission entry)`: -- Uniform shape every turn: **two EIP-712 signatures** (committer + revealer), committer preimage in calldata. Roles derived from `turnId % 2` (matching `getCommitAuthForDualSigned`). -- Switch turns use the same shape. The non-acting player signs a `NO_OP` (move 126); engine ignores their half at batch time using the live `playerSwitchForTurnFlag`. -- Manager hashes committer preimage, verifies committer sig over `SignedCommit{committerMoveHash, …}` and revealer sig over `DualSignedReveal{committerMoveHash, …}`, writes to `moveBuffer[storageKey][turnId]`. **No execute runs.** -- Updates `lastSubmitTimestamp` for timeout tracking. - -**Why two sigs.** Without a committer sig, a malicious revealer could pick any preimage `P*`, sign `DualSignedReveal{committerMoveHash: keccak(P*), …}`, and submit unilaterally — the contract would play `P*` as the committer's move with no committer involvement. Today's `executeWithDualSignedMoves` blocks this only via `msg.sender == committer`, which is fragile and not relayer-friendly. Phase 0 (§9) lifts the same fix into the existing function before any batching ships, so both paths share one security model. - -### 2.2 Per-batch execute - -`Engine.executeBatch(battleKey)`: -- Anyone can call (sigs were checked at submission). -- Reads every currently buffered entry `[startTurn, startTurn + numTurnsBuffered)`, runs each in sequence inside transient shadow storage, flushes once at end. -- The **transient mirror** of `turnId` advances inside the loop. Persistent `BattleData.turnId` advances only during the final flush. -- Batch execution always consumes the full pending buffer. There is no partial-batch mode in v1. -- Processed buffer slots are not cleared — the unbounded mapping leaves them for on-chain replay. Slot reuse across battles comes from `MappingAllocator`. - -### 2.3 Fallback / stalls - -Fully separate write paths. Legacy `DefaultCommitManager.commitMove`/`revealMove` writes `config.p0Move` etc. and triggers `execute()` immediately; the batched path never reads that storage. A battle can alternate between modes turn-by-turn. Timeout via `Engine.end()` covers full stalls. +## What shipped + +### Core mechanism +- **PvP buffered submission.** `SignedCommitManager.submitTurnMoves` writes per-turn moves + to a manager-owned buffer; `executeBuffered` drains via the new + `Engine.executeBatchedTurns`. Switch turns reuse the same shape (non-acting player signs + `NO_OP`). +- **Off-chain CPU batched mode** (`BatchedCPUMoveManager`).

Forced switches and game-over - -### 6.1 Forced switch (KO without game-over) - -Both players sign for every turn. The non-acting player signs `NO_OP`. At batch time, the engine reads the live `playerSwitchForTurnFlag` (cheap — in shadow state) and dispatches: -- `flag == 2`: process both halves. -- `flag == 0`: process p0 only, ignore p1's NO_OP. -- `flag == 1`: mirror. - -A player who maliciously signs a non-NO_OP on a turn they shouldn't act has bound themselves cryptographically, but the engine ignores the move. A player who refuses to sign stalls the batched flow; legacy single-turn paths remain as fallback. - -Submission validates only cheap invariants (battle exists, not over at last flush, append position, sig). It does **not** project `playerSwitchForTurnFlag`, since that would require replaying every unprocessed turn. - -### 6.2 Game-over mid-batch - -`_executeInternal` already breaks when `winnerIndex != 2`. Same check stops the batch loop. Because batch execution consumes the full pending buffer, any unexecuted buffered entries after game-over remain in storage for replay but are no longer live; `numTurnsBuffered` is set to zero at flush. - -### 6.3 Status-induced skip-turn - -`shouldSkipTurn` already auto-clears in `_handleMove`.

Migration - -Add new entry points alongside existing ones.

Timeout reads `lastSubmitTimestamp` and `lastExecuteTimestamp` — whichever is more recent. - ---- - -## 9. Phased rollout - -**Phase 0 — Dual-sig security fix (preflight, ships first, independent of batching).** The existing `executeWithDualSignedMoves` relies on `msg.sender == committer` as the committer's binding. Without that check, a malicious revealer could sign `DualSignedReveal{committerMoveHash: keccak(P*), …}` for any preimage `P*` they choose and submit unilaterally — the contract would happily compute `committerMoveHash = keccak(P*)`, recover the revealer's sig, and play `P*` as the committer's move. The check is load-bearing today, but it's also fragile: any future evolution of the flow that drops or weakens it (relayers, batching, alt entry points) silently re-opens the hole. - -Fix: require an explicit committer signature over the existing `SignedCommit{moveHash, battleKey, turnId}` struct (already used by `commitWithSignature`). - -- Modify `executeWithDualSignedMoves` to take an additional `bytes calldata committerSignature` parameter. -- Recover `committerSignature` over `SignedCommit{committerMoveHash, battleKey, turnId}`; require equality with `committer`. -- Drop the `msg.sender == committer` check; the function becomes relayer-friendly (anyone with both sigs + the preimage can submit). -- Breaking signature change. Update all callers (tests, `BattleHelper`, anything off-chain that calls this function) in the same PR. No deployed callers in production yet. -- New tests: missing committer sig reverts; wrong committer signer reverts; submission by a third party with both valid sigs succeeds; revealer cannot submit a self-chosen committer preimage (regression). - -This phase ships before any batching work. It hardens the existing flow on its own merits and unifies the security model so the batched path in Phase 2 inherits the same shape (§4.1) without surprises. - -**Phase 0.1 — Instrumentation refresh.** `test/BatchInstrumentationTest.sol` already wires `vm.startStateDiffRecording` for the clean damage-trade case. Add scenarios: effect-heavy turn (status DOT + StatBoosts active), forced-switch turn, multi-mon turn. Lock final batch-size guidance. - -**Phase 0.5 — Helper extraction (no behavior change).** Replace direct `MonState`/`globalKV`/effect-data SLOAD/SSTORE in `Engine.sol` with §5.2 helpers, with `_shadowActive` permanently `false`. Snapshot diff should be roughly flat. - -**Phase 1 — Single-turn shadow.** Implement transient mirrors + lazy-load/dirty-flag bookkeeping. Wire helpers to consult `_shadowActive`. Add `executeShadowed(bytes32 battleKey)` that does `execute()`'s work inside the shadow layer (hydrate → run one turn → flush). Existing test suite should pass against it. B=1 will be slightly *worse* than today's `execute()` due to bookkeeping overhead; expected. - -**Phase 2 — PvP per-turn submission + batch execute.** Extend `SignedCommitManager` with `submitTurnMoves`. Add per-turn move buffer mapping and `numTurnsBuffered` / `numTurnsExecuted` counters. Add `Engine.executeBatch` with flag-based dispatch (§6.1), requiring execution of all currently buffered turns. Equivalence tests + gas snapshots. - -**Phase 2.5 — CPU mode.** Extend `CPUMoveManager` with `selectMoveWithStateHint` (§7.4). Reuse Phase-2 buffer + `executeBatch`. Equivalence test: 24-turn CPU game via legacy `selectMove × 24` vs `selectMoveWithStateHint × 24 + executeBatch × 3` produces identical end state. - -**Phase 3 — Transpiler parity (deferred).** Local TS engine continues running single-turn `execute()` against hydrated state.
