From 2abc453b546e113ddb43d86b232328d74842dd5f Mon Sep 17 00:00:00 2001 From: Claude Date: Thu, 21 May 2026 20:21:42 +0000 Subject: [PATCH 01/65] add 3 storage-access profile scenarios to BatchInstrumentationTest Closes Phase 0.1 of OPT_PLAN: locks per-turn SLOAD/SSTORE budgets for effect-heavy, forced-switch, and multi-mon-switch turn shapes alongside the existing clean-trade scenario. Records the four numbers in a comment block so the shadow layer has a concrete budget to clear. PerTurnTickEffect is a 50-LOC mock with the RoundStart/RoundEnd/AfterDamage bits set, avoiding the StatBoosts+BurnStatus dependency chain for an instrumentation-only test where only the access pattern matters. https://claude.ai/code/session_01AWNvQmDFzSK7sYMDXtyXD5 --- test/BatchInstrumentationTest.sol | 225 +++++++++++++++++++++++++++++- test/mocks/PerTurnTickEffect.sol | 48 +++++++ 2 files changed, 272 insertions(+), 1 deletion(-) create mode 100644 test/mocks/PerTurnTickEffect.sol diff --git a/test/BatchInstrumentationTest.sol b/test/BatchInstrumentationTest.sol index 1d1fb6d2..04387645 100644 --- a/test/BatchInstrumentationTest.sol +++ b/test/BatchInstrumentationTest.sol @@ -25,10 +25,22 @@ import {TypeCalculator} from "../src/types/TypeCalculator.sol"; import {ITypeCalculator} from "../src/types/ITypeCalculator.sol"; import {SignedCommitHelper} from "./abstract/SignedCommitHelper.sol"; +import {EffectAttack} from "./mocks/EffectAttack.sol"; +import {PerTurnTickEffect} from "./mocks/PerTurnTickEffect.sol"; import {TestTeamRegistry} from "./mocks/TestTeamRegistry.sol"; -/// Counts SLOAD / SSTORE access patterns on a warm steady-state turn, to ground the PLAN_OPT.md +/// Counts SLOAD / SSTORE access patterns on a warm steady-state turn, to ground the OPT_PLAN.md /// gas math in real data instead of estimates. +/// +/// Per-turn budgets (locked by §11 Phase 0.1; run forge test -vv --match-contract BatchInstrumentationTest): +/// clean damage trade : 16 cold SLOADs / 10 SSTOREs / 16 unique slots / 3 multi-write +/// effect-heavy turn : 20 cold SLOADs / 16 SSTOREs / 20 unique slots / 5 multi-write +/// forced-switch turn : 10 cold SLOADs / 5 SSTOREs / 10 unique slots / 1 multi-write +/// multi-mon switch turn: 16 cold SLOADs / 8 SSTOREs / 16 unique slots / 2 multi-write +/// +/// These four numbers are the per-turn gas budget the §5 shadow layer has to clear at B>=2. +/// Multi-write slots (same slot written 2+ times in one turn) are the biggest amortization +/// targets — at B=2 a previously-multi-written slot becomes one shadow read + one flush. contract BatchInstrumentationTest is SignedCommitHelper { uint256 constant MONS_PER_TEAM = 4; @@ -320,4 +332,215 @@ contract BatchInstrumentationTest is SignedCommitHelper { console.log("Unique slots touched :", unique); console.log("Slots written 2+ times in turn :", multiWrite); } + + /// @dev Shared log shape so all four scenarios produce comparable per-turn numbers. + function _logDiffsBlock(string memory label, Vm.AccountAccess[] memory diffs) internal { + ( + uint256 totalSload, + uint256 totalSstore, + uint256 coldSload, + uint256 warmSload, + uint256 coldSstore, + uint256 warmSstore, + uint256 z2nz, + uint256 nz2nz, + uint256 noop, + uint256 unique, + uint256 multiWrite + ) = _summarizeAccesses(diffs); + + console.log(label); + console.log("Total SLOADs :", totalSload); + console.log(" Cold (first-touch in tx) :", coldSload); + console.log(" Warm :", warmSload); + console.log("Total SSTOREs :", totalSstore); + console.log(" Cold (first-touch in tx) :", coldSstore); + console.log(" Warm :", warmSstore); + console.log(" zero -> nonzero :", z2nz); + console.log(" nonzero -> nonzero (diff) :", nz2nz); + console.log(" no-op (same value) :", noop); + console.log("Unique slots touched :", unique); + console.log("Slots written 2+ times in turn :", multiWrite); + } + + /// @dev Records a state diff over a single `_fastTurn` call and prints the summary block. + function _profileTurn( + string memory label, + bytes32 battleKey, + uint8 p0Move, + uint8 p1Move, + uint16 p0Extra, + uint16 p1Extra + ) internal { + vm.startStateDiffRecording(); + _fastTurn(battleKey, p0Move, p1Move, p0Extra, p1Extra); + Vm.AccountAccess[] memory diffs = vm.stopAndReturnStateDiff(); + _logDiffsBlock(label, diffs); + } + + /// @notice Per-turn storage profile when both active mons carry a multi-step effect. + /// @dev Setup: ALICE & BOB each carry a PerTurnTickEffect attached to their active mon + /// (added via EffectAttack in turn 1).

Buffer layout matches OPT_PLAN §3 exactly (one uint256 per turn): 8/16/104 bits for p0 move/extra/salt + same for p1. Counters packed into a single slot: (numTurnsExecuted | numTurnsBuffered | lastSubmitTimestamp). executeBuffered lives on the manager rather than the engine so the engine stays ignorant of any specific commit manager. Manager dispatches via ENGINE.getPlayerSwitchForTurnFlagForBattleState between iterations. resetCallContext gains four additional transient clears (tempRNG, koOccurredFlag, tempPreDamage, effectsDirtyBitmap) so batched in-tx execution matches legacy per-tx execution where the EVM auto-clears all transients on tx entry.

Asserts BattleData, MonStates, active mons, KO bitmaps, winner all match across two parallel battles. - BufferSubmissionTest (12 tests): happy path, relayer submission, wrong committer/revealer signer, missing committer sig (regression for the unilateral-revealer attack from OPT_PLAN §9), missing revealer sig, wrong turnId, replay, battle-not-started, empty-buffer execute, counter accounting, timestamp tracking. - BatchEdgeTest (5 tests): forced-switch dispatch (flag != 2), single- side switch, mid-batch game-over (ex advances by actually-executed not buffered count; remaining entries become dead), legacy->batched and batched->legacy mode alternation in the same battle. - BatchGasTest (3 benchmarks): B in {2, 4, 8} comparison of legacy vs batched total gas. Surfaces the critical finding that the batched flow is currently MORE expensive than legacy (~33-36% more) -- the per-turn buffer + counter SSTOREs dominate, and the cross-sub-turn EVM warm- storage discount alone isn't enough to recoup. Shadow layer (deferred Phase 1) needed to deliver the gas-savings claim from OPT_PLAN §1. BatchHelper.sol centralizes _buildTurnSubmission / _submitTurnMoves / _executeBuffered for reuse across the four suites. https://claude.ai/code/session_01AWNvQmDFzSK7sYMDXtyXD5 --- test/BatchEdgeTest.sol | 343 +++++++++++++++++++++++++++++++++ test/BatchEquivalenceTest.sol | 344 ++++++++++++++++++++++++++++++++++ test/BatchGasTest.sol | 236 +++++++++++++++++++++++ test/BufferSubmissionTest.sol | 295 +++++++++++++++++++++++++++++ test/abstract/BatchHelper.sol | 125 ++++++++++++ 5 files changed, 1343 insertions(+) create mode 100644 test/BatchEdgeTest.sol create mode 100644 test/BatchEquivalenceTest.sol create mode 100644 test/BatchGasTest.sol create mode 100644 test/BufferSubmissionTest.sol create mode 100644 test/abstract/BatchHelper.sol diff --git a/test/BatchEdgeTest.sol b/test/BatchEdgeTest.sol new file mode 100644 index 00000000..80aac7d9 --- /dev/null +++ b/test/BatchEdgeTest.sol @@ -0,0 +1,343 @@ +// SPDX-License-Identifier: AGPL-3.0 +pragma solidity ^0.8.0;

Each entry: short context + the call made + why. + +### Cross-cutting + +- **Shadow layer deferred to follow-up.** §1-§5 of OPT_PLAN are organized around a transient shadow that mirrors `MonState` / `globalKV` / effect-slot reads inside `executeBatch`, then flushes once at the end. The motivating amortization (cold SLOADs are paid once per batch instead of once per turn) is *already* delivered for free by EVM warm-slot semantics: when `executeBatch` loops `_executeInternal` in one tx, the second iteration sees the slots from the first iteration as warm (100 gas) instead of cold (2100). The shadow's additional win is SSTORE deduplication across sub-turns (~5k per dedup'd write × multi-write count per turn). For v1 the warm-slot baseline plus single-tx amortization is enough to ship the gas-savings claim; the SSTORE-dedup follow-up is queued for v2. This deferral means Phases 0.5 and 1 stay in §11 unchecked, and Phase 2's `executeBatch` is built as a simple sub-turn loop over `_executeInternal`. + +### Phase 2 + +- **`executeBuffered` lives on the manager, not the engine.** §4.2 had `Engine.executeBatch(bytes32)` as a new engine entry point. Putting it on the manager instead keeps the engine ignorant of any specific commit-manager and avoids a new engine ↔ manager callback dance (engine asking the manager for buffer entries). The manager already has `IEngine`, so the loop is straightforward: read buffer slot → read live `playerSwitchForTurnFlag` → call `executeWithMoves` or `executeWithSingleMove`. No new engine surface needed except an extension to `resetCallContext`. Trade-off: the engine can never read from the buffer directly (e.g. for a single batch-aware `_executeInternal`-style optimization in the future). For v1 this is the right call. +- **Buffer keyed by `battleKey`, not `storageKey`.** §3 keyed `moveBuffer` by `storageKey` for slot reuse parity with `BattleConfig`. The manager doesn't actually care about slot reuse (entries are tiny — one `uint256` per turn), and `battleKey` is already unique per game via `pairHashNonce` increment. Using `battleKey` directly avoids needing a public `getStorageKey(bytes32)` accessor on the engine and keeps the manager fully decoupled from `MappingAllocator`. +- **Single `uint256` packed slot, no struct in storage.** §3 specified a `PackedTurnEntry` struct. Storing the packed `uint256` directly is one fewer SLOAD (no Solidity-generated wrapper), and the §3 bit layout is preserved exactly: `[p0Move 8 | p0Extra 16 | p0Salt 104 | p1Move 8 | p1Extra 16 | p1Salt 104]`. Internal `_packBufferedTurn` / `_unpackBufferedTurn` helpers handle the bit ops. +- **Extended `resetCallContext` instead of adding `resetPerTurnTransients`.** First pass added a parallel `resetPerTurnTransients()` external on the engine. The existing `resetCallContext()` already clears half of what was needed (per-turn move/salt encoded slots + `battleKeyForWrite` / `storageKeyForWrite`); extending it to also zero `tempRNG` / `koOccurredFlag` / `tempPreDamage` / `effectsDirtyBitmap` covers the rest and avoids two near-identical functions on `IEngine`. In legacy single-turn flow nothing changes — `resetCallContext` is only called by foundry test harnesses, where the extra zero TSTOREs are negligible. In batched flow `executeBuffered` calls `resetCallContext()` between sub-turns so each sub-turn starts with the same transient state the legacy per-tx flow would see. The four added clears are documented inline at `Engine.sol`'s `resetCallContext` body. +- **Game-over short-circuit test design.** First pass used a 2-mon game with HP=1 + power=100 on both sides, expecting "both mons die in turn 1." Trace showed the slower player's move short-circuits (`prevPlayerSwitchForTurnFlag != 2` after the faster player's KO chains into `_checkForGameOverOrKO`), so only ONE mon dies per damage trade. With 2-mon teams this means the battle needs ≥4 turns to wipe one side, and symmetric setups don't deterministically reach game-over within the buffered range. Rewrote with asymmetric setups (p0 fast/strong, p1 slow/glass) so p0 always KOs first and never gets KO'd — game ends deterministically on turn 3, the loop break is provably exercised. +- **Gas finding (critical):** the v1 batched flow (no shadow layer) is **measurably more expensive** than legacy dual-signed-per-turn execution. `test/BatchGasTest.sol` shows: + + | B | legacy | batched | delta | + |---|---|---|---| + | 2 | 211,458 | 282,674 | +71k (+33%) | + | 4 | 370,145 | 500,417 | +130k (+35%) | + | 8 | 687,748 | 936,847 | +249k (+36%) | + + Per-turn overhead breakdown: each `submitTurnMoves` costs ~22k cold-→-warm SSTORE for the buffer slot + ~5k warm-→-warm SSTORE for the counter slot + ~2k event + ~6k for the two sig recoveries (same as legacy). That's ~30k/turn more than legacy. The `executeBuffered` amortization across sub-turns only saves ~2k/turn per cold→warm engine SLOAD via EVM warm-storage discount (~16 cold SLOADs on a clean trade × 2k ≈ 32k saved per turn-after-the-first), which doesn't recoup the per-submission overhead until B is very large. + + The OPT_PLAN's gas claim (§1) was predicated on the §5 transient shadow layer doing SSTORE deduplication across sub-turns (the second sub-turn's `BattleData.turnId` etc. SSTOREs collapse to one final flush). Without the shadow, the engine SSTOREs every turn unchanged. **Phase 1 (shadow) is required to deliver the gas-savings claim.** Phase 2 as shipped delivers the decoupling API + correctness gate, plus the substrate Phase 1 will sit on top of. + +### Phase 0.1 + +- **Effect-heavy mock.** §0.1 mentioned "StatBoosts-style multi-stat effect + BurnStatus". Both have heavy external dependencies (StatBoosts needs its own deploy and per-mon snapshot KV; BurnStatus needs the StatBoosts instance). For an instrumentation test where only the per-turn storage-access pattern matters, that's overkill. Wrote a 50-LOC `test/mocks/PerTurnTickEffect.sol` that hooks RoundStart + RoundEnd + AfterDamage + ALWAYS_APPLIES and bumps a counter in `data` each tick. Same SLOAD/SSTORE shape (effect slot reads, data SSTOREs, count SLOADs in `_runEffects`), zero external setup. If the shadow layer ever needs differential testing against StatBoosts/Burn specifically, that belongs in Phase 1's effect-shadow correctness suite, not here. +- **Multi-mon scenario interpretation.** §0.1 wording was "all four mons referenced via onUpdateMonState listeners on bench mons". Production engine doesn't actually touch bench mons during a regular turn — only the active mons on each side. The natural multi-slot turn is a switch turn where p0 switches mon 0→1 while p1 attacks (touches p0 mon 0, p0 mon 1, p1 mon 0 = three distinct mon-state slots). Implemented that interpretation; logs show 16 cold SLOADs / 16 unique slots — slightly fewer than a clean trade because no second-attack SSTORE pattern. +- **Forced-switch entry point.** `_fastTurn` goes through `executeWithDualSignedMoves`, which reverts `NotTwoPlayerTurn()` once `playerSwitchForTurnFlag != 2`. Added a `_fastSinglePlayerTurn` helper that routes through `executeSinglePlayerMove(...)` with `vm.prank(actingPlayer)`. This is the same dispatch the production code does and matches what the batch flow will do via §6.1. + diff --git a/snapshots/BetterCPUInlineGasTest.json b/snapshots/BetterCPUInlineGasTest.json index 56b5eac7..0d1a9747 100644 --- a/snapshots/BetterCPUInlineGasTest.json +++ b/snapshots/BetterCPUInlineGasTest.json @@ -1,8 +1,8 @@ { "Flag0_P0ForcedSwitch": "25377", "Turn0_Lead": "107260", - "Turn1_BothAttack": "240701", - "Turn2_BothAttack": "214777", - "Turn3_BothAttack": "210801", - "Turn4_BothAttack": "210805" + "Turn1_BothAttack": "241228", + "Turn2_BothAttack": "215304", + "Turn3_BothAttack": "211328", + "Turn4_BothAttack": "211332" } \ No newline at end of file diff --git a/snapshots/EngineGasTest.json b/snapshots/EngineGasTest.json index cf70da84..5562539d 100644 --- a/snapshots/EngineGasTest.json +++ b/snapshots/EngineGasTest.json @@ -1,21 +1,21 @@ { - "B1_Execute": "912113", + "B1_Execute": "913694", "B1_Setup": "850985", - "B2_Execute": "659466", + "B2_Execute": "661047", "B2_Setup": "307623", - "Battle1_Execute": "443036", + "Battle1_Execute": "444090", "Battle1_Setup": "826189", - "Battle2_Execute": "364327", + "Battle2_Execute": "365381", "Battle2_Setup": "245514", - "External_Execute": "451382", + "External_Execute": "454544", "External_Setup": "816904", - "FirstBattle": "2920585", - "Inline_Execute": "317825", + "FirstBattle": "2927963", + "Inline_Execute": "320987", "Inline_Setup": "227355", "Intermediary stuff": "45252", - "SecondBattle": "2957006", + "SecondBattle": "2964911", "Setup 1": "1712677", "Setup 2": "312571", "Setup 3": "353891", - "ThirdBattle": "2293275" + "ThirdBattle": "2300653" } \ No newline at end of file diff --git a/snapshots/EngineOptimizationTest.json b/snapshots/EngineOptimizationTest.json index d710c64e..d3c79c6c 100644 --- a/snapshots/EngineOptimizationTest.json +++ b/snapshots/EngineOptimizationTest.json @@ -1,4 +1,4 @@ { - "ExternalStaminaRegen": "389950", - "InlineStaminaRegen": "1035668" + "ExternalStaminaRegen": "391004", + "InlineStaminaRegen": "1037249" } \ No newline at end of file diff --git a/snapshots/FullyOptimizedInlineGasTest.json b/snapshots/FullyOptimizedInlineGasTest.json index 180cde78..b8a13a0e 100644 --- a/snapshots/FullyOptimizedInlineGasTest.json +++ b/snapshots/FullyOptimizedInlineGasTest.json @@ -1,7 +1,7 @@ { - "Fast_Battle1": "1895389", - "Fast_Battle2": "1792891", - "Fast_Battle3": "1314750", + "Fast_Battle1": "1903735", + "Fast_Battle2": "1801833", + "Fast_Battle3": "1323096", "Fast_Setup_1": "1345979", "Fast_Setup_2": "219252", "Fast_Setup_3": "215455" diff --git a/snapshots/InlineEngineGasTest.json b/snapshots/InlineEngineGasTest.json index 7536bb1d..2f44f82c 100644 --- a/snapshots/InlineEngineGasTest.json +++ b/snapshots/InlineEngineGasTest.json @@ -1,16 +1,16 @@ { - "B1_Execute": "896745", + "B1_Execute": "901488", "B1_Setup": "782990", - "B2_Execute": "621601", + "B2_Execute": "626344", "B2_Setup": "286671", - "Battle1_Execute": "398480", + "Battle1_Execute": "401642", "Battle1_Setup": "758186", - "Battle2_Execute": "317777", + "Battle2_Execute": "320939", "Battle2_Setup": "226783", - "FirstBattle": "2606959", - "SecondBattle": "2604950", + "FirstBattle": "2614337", + "SecondBattle": "2612855", "Setup 1": "1636824", "Setup 2": "321759", "Setup 3": "317965", - "ThirdBattle": "1979658" + "ThirdBattle": "1987036" } \ No newline at end of file diff --git a/snapshots/StandardAttackPvPGasTest.json b/snapshots/StandardAttackPvPGasTest.json index 8909a4ad..64e649fc 100644 --- a/snapshots/StandardAttackPvPGasTest.json +++ b/snapshots/StandardAttackPvPGasTest.json @@ -1,7 +1,7 @@ { - "Turn0_Lead": "71144", - "Turn1_BothAttack": "121432", - "Turn2_BothAttack": "81643", - "Turn3_BothAttack": "81682", - "Turn4_BothAttack": "81698" + "Turn0_Lead": "71754", + "Turn1_BothAttack": "122049", + "Turn2_BothAttack": "82253", + "Turn3_BothAttack": "82299", + "Turn4_BothAttack": "82308" } \ No newline at end of file From 3aa102606b7b61b26de89ad48bdf2a0a89326f89 Mon Sep 17 00:00:00 2001 From: Claude Date: Thu, 21 May 2026 22:08:26 +0000 Subject: [PATCH 05/65] =?UTF-8?q?add=20transient=20shadow=20layer=20per=20?= =?UTF-8?q?OPT=5FPLAN=20=C2=A75=20(does=20NOT=20save=20gas)?= MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Implements the full shadow infrastructure described in OPT_PLAN §5.1/§5.2: eight shadow helpers (MonState, KO bitmap, BattleData, effect slots, effect counts, globalKV) with both shadow and storage branches, lazy-load on writes, dirty-bit tracking, and a `_flushShadow` walker that SSTOREs once at end of batch. New `Engine.executeBatchedTurns(bytes32, uint256[])` external entry activates shadow, loops sub-turns with flag-based dispatch per §6.1, flushes, returns (executedCount, winner). Manager's `executeBuffered` now delegates to it. Design decisions: - Helpers take BattleConfig storage cfg explicitly (not via storageKeyForWrite) so external view getters (getEffects, getKOBitmap, etc.) work from staticcall contexts where the transient cache is empty. - Reads check loaded bit (set only on writes), fall back to SLOAD if not loaded — keeps reads view-compatible (no TSTORE in view functions). - BattleData slot 1 has helpers but stayed on storage refs in _executeInternal to avoid a ~13-function refactor; engine continues writing BattleData via storage refs. CRITICAL gas finding (test/BatchGasTest.sol, B=8 clean trade): legacy (per-turn) : 687k -> 849k (+161k regression) batched (submit+execute) : 937k -> 1172k (+235k regression) batched - legacy gap : +249k -> +323k (gap GREW with shadow) The shadow layer: - Adds ~20k/turn overhead to the LEGACY path (memory pattern instead of storage refs; _shadowActive TLOAD check on every helper call paid even when shadow is inactive). - Saves ~24k/sub-turn on the executeBuffered path (SSTORE coalescing for MonState + effect slots + counts + KO bitmap + globalKV). - Per-submission overhead (~85k each) is unchanged — submission infrastructure, not engine-state infrastructure. The shadow can't recover the 8 x 85k = 680k of submission cost. Conclusion: OPT_PLAN §1's gas-savings claim is NOT architecturally achievable with the per-turn-SSTORE submission scheme. To beat dual-signed-per-turn execution, batching needs a different submission design (Merkle-rooted batch claims, sig aggregation, etc.). The shadow layer is correct and stays in place as the substrate for any future submission redesign, but on its own it's a net loss. All 533 existing tests still pass.

Each entry: short context + the c The OPT_PLAN's gas claim (§1) was predicated on the §5 transient shadow layer doing SSTORE deduplication across sub-turns (the second sub-turn's `BattleData.turnId` etc. SSTOREs collapse to one final flush).

Eight §5.2 helpers added with both shadow and storage branches. `_flushShadow` walks dirty bits and SSTOREs once at end of batch. New engine entry `executeBatchedTurns(bytes32, uint256[])` activates shadow, loops sub-turns with flag-based dispatch, flushes, returns executed count + winner. Manager's `executeBuffered` now delegates to this entry. +- **Helpers take `BattleConfig storage cfg` explicitly.** First pass had effect/KO helpers read `battleConfig[storageKeyForWrite]` internally. That broke when external view getters (`getEffects`, `getKOBitmap`) called helpers outside execute — `storageKeyForWrite` is `bytes32(0)` there, so helpers read an empty config and returned 0 effects. Fix: thread cfg through every helper signature. 53 tests failed before the fix; all 533 pass after. +- **Reads are view-compatible (no TSTORE on read).** §5.2's spec implied lazy-load on first read (TSTORE to cache). That's incompatible with `view` callers — Solidity treats TSTORE as state mutation, breaking staticcall from external view getters. Redesigned reads to: check loaded bit (set only by writes), return shadow value if set, else fall back to direct SLOAD. Lazy-load happens only on writes (which are non-view anyway). External view getters can now call shadow read helpers during execute and see in-progress state correctly. +- **External view getters route through shadow.** `getMonStateForBattle`, `getGlobalKV`, `getEffects` all consult shadow when called during execute (effects calling these as part of their hook see the latest values). Outside execute, shadow is inactive so they read storage as before. +- **BattleData stayed on storage refs.** §5.1 lists BattleData slot 1 as shadowed, and I added `_shadowReadBattleData` / `_shadowWriteBattleData` / `_packBattleData` / `_unpackBattleData` / `_flushShadowBattleData`. But refactoring `_executeInternal` and its helpers from `BattleData storage battle = battleData[battleKey]` to the memory pattern would have rippled through ~13 function signatures and required careful checkpoint handling around every external callback (move/effect hooks that re-enter the engine and might mutate `battle.*`). For Phase 1 I left BattleData on the storage-ref pattern — it's still consistent (engine writes/reads via storage refs throughout `_executeInternal`), just not deduplicated across sub-turns.

To beat dual-signed-per-turn execution, batching would need a fundamentally different submission scheme — Merkle-rooted batch claims, signature aggregation (BLS / SNARK), or off-chain ordering with on-chain finality proofs. None of those fit in the per-turn-SSTORE model. + + The batched API still has real value (single-tx execution off-peak, flexibility for relayers, async submission UX), just not raw gas savings. The shadow layer remains in place because it's correct and the substrate is there if a future submission redesign closes the gap — but on its own, it's a net loss to ship. + ### Phase 0.1 - **Effect-heavy mock.** §0.1 mentioned "StatBoosts-style multi-stat effect + BurnStatus". Both have heavy external dependencies (StatBoosts needs its own deploy and per-mon snapshot KV; BurnStatus needs the StatBoosts instance). For an instrumentation test where only the per-turn storage-access pattern matters, that's overkill. Wrote a 50-LOC `test/mocks/PerTurnTickEffect.sol` that hooks RoundStart + RoundEnd + AfterDamage + ALWAYS_APPLIES and bumps a counter in `data` each tick. Same SLOAD/SSTORE shape (effect slot reads, data SSTOREs, count SLOADs in `_runEffects`), zero external setup. If the shadow layer ever needs differential testing against StatBoosts/Burn specifically, that belongs in Phase 1's effect-shadow correctness suite, not here. diff --git a/snapshots/BetterCPUInlineGasTest.json b/snapshots/BetterCPUInlineGasTest.json index 0d1a9747..78443013 100644 --- a/snapshots/BetterCPUInlineGasTest.json +++ b/snapshots/BetterCPUInlineGasTest.json @@ -1,8 +1,8 @@ { -

Each entry: short context + the c The OPT_PLAN's gas claim (§1) was predicated on the §5 transient shadow layer doing SSTORE deduplication across sub-turns (the second sub-turn's `BattleData.turnId` etc. SSTOREs collapse to one final flush). Without the shadow, the engine SSTOREs every turn unchanged. **Phase 1 (shadow) is required to deliver the gas-savings claim.** Phase 2 as shipped delivers the decoupling API + correctness gate, plus the substrate Phase 1 will sit on top of. -### Phase 0.5 + Phase 1 (shadow layer fully implemented) - -- **Shadow infrastructure built.** §5.1's full slot inventory landed: MonState (per-mon, lazy-loaded), KO bitmaps (BattleConfig slot 2), BattleData slot 1 (helpers added but BattleData itself stayed on storage refs — see below), effect slots (per §5.1.1: 144 keys, two transient regions per slot), effect counts (3 packed mirrors), and globalKV (sparse 16-slot buffer). Eight §5.2 helpers added with both shadow and storage branches. `_flushShadow` walks dirty bits and SSTOREs once at end of batch. New engine entry `executeBatchedTurns(bytes32, uint256[])` activates shadow, loops sub-turns with flag-based dispatch, flushes, returns executed count + winner. Manager's `executeBuffered` now delegates to this entry. -- **Helpers take `BattleConfig storage cfg` explicitly.** First pass had effect/KO helpers read `battleConfig[storageKeyForWrite]` internally. That broke when external view getters (`getEffects`, `getKOBitmap`) called helpers outside execute — `storageKeyForWrite` is `bytes32(0)` there, so helpers read an empty config and returned 0 effects. Fix: thread cfg through every helper signature. 53 tests failed before the fix; all 533 pass after. -- **Reads are view-compatible (no TSTORE on read).** §5.2's spec implied lazy-load on first read (TSTORE to cache). That's incompatible with `view` callers — Solidity treats TSTORE as state mutation, breaking staticcall from external view getters. Redesigned reads to: check loaded bit (set only by writes), return shadow value if set, else fall back to direct SLOAD. Lazy-load happens only on writes (which are non-view anyway). External view getters can now call shadow read helpers during execute and see in-progress state correctly. -- **External view getters route through shadow.** `getMonStateForBattle`, `getGlobalKV`, `getEffects` all consult shadow when called during execute (effects calling these as part of their hook see the latest values). Outside execute, shadow is inactive so they read storage as before. -- **BattleData stayed on storage refs.** §5.1 lists BattleData slot 1 as shadowed, and I added `_shadowReadBattleData` / `_shadowWriteBattleData` / `_packBattleData` / `_unpackBattleData` / `_flushShadowBattleData`. But refactoring `_executeInternal` and its helpers from `BattleData storage battle = battleData[battleKey]` to the memory pattern would have rippled through ~13 function signatures and required careful checkpoint handling around every external callback (move/effect hooks that re-enter the engine and might mutate `battle.*`). For Phase 1 I left BattleData on the storage-ref pattern — it's still consistent (engine writes/reads via storage refs throughout `_executeInternal`), just not deduplicated across sub-turns. If the architectural finding below changes, this becomes the next optimization to land. -- **Architectural finding (definitive): shadow layer does NOT deliver gas savings.** Measured with `test/BatchGasTest.sol` (8 sub-turn clean damage trade): - - | Path | Before Phase 0.5/1 | After Phase 0.5/1 | Delta | - |---|---|---|---| - | legacy (per-turn) — B=8 total | 687,748 | 848,960 | **+161k** (+23%) | - | batched (submit + execute) — B=8 total | 936,847 | 1,172,164 | **+235k** (+25%) | - | batched − legacy gap — B=8 | +249k (+36%) | +323k (+38%) | gap grew | - - The shadow layer: - - Adds ~20k/turn overhead to the legacy path (memory pattern instead of storage refs; helpers do a `_shadowActive` TLOAD check + memory pack/unpack on every read, paid even when shadow is inactive). This regresses every existing gas test by 1-7k. - - Saves ~24k/sub-turn on the executeBuffered path (within-batch SSTORE coalescing for MonState + effect slots + counts + KO bitmap + globalKV). That's roughly the per-sub-turn SSTORE work that gets deferred to the single final flush. - - The per-submission overhead (~85k each: sig recovery + buffer SSTORE + counter SSTORE) is unchanged by the shadow — it's submission infrastructure, not engine-state infrastructure. Eight submissions × 85k = 680k of overhead the shadow can't recover. - - Conclusion: the gas-savings claim in OPT_PLAN §1 is **not architecturally achievable** with a per-turn buffer design. The 85k/turn submission cost is the floor, and engine-side savings from shadow (~24k/turn × N−1 amortized) don't close it. To beat dual-signed-per-turn execution, batching would need a fundamentally different submission scheme — Merkle-rooted batch claims, signature aggregation (BLS / SNARK), or off-chain ordering with on-chain finality proofs. None of those fit in the per-turn-SSTORE model. - - The batched API still has real value (single-tx execution off-peak, flexibility for relayers, async submission UX), just not raw gas savings. The shadow layer remains in place because it's correct and the substrate is there if a future submission redesign closes the gap — but on its own, it's a net loss to ship. - ### Phase 0.1 - **Effect-heavy mock.** §0.1 mentioned "StatBoosts-style multi-stat effect + BurnStatus". Both have heavy external dependencies (StatBoosts needs its own deploy and per-mon snapshot KV; BurnStatus needs the StatBoosts instance). For an instrumentation test where only the per-turn storage-access pattern matters, that's overkill. Wrote a 50-LOC `test/mocks/PerTurnTickEffect.sol` that hooks RoundStart + RoundEnd + AfterDamage + ALWAYS_APPLIES and bumps a counter in `data` each tick.

Eliminating per-turn buffer SSTORE (e.g. via rolling-hash commitment) is the highest-leverage optimization. https://claude.ai/code/session_01AWNvQmDFzSK7sYMDXtyXD5 --- test/BatchAccessProfileTest.sol | 352 ++++++++++++++++++++++++++++++++ 1 file changed, 352 insertions(+) create mode 100644 test/BatchAccessProfileTest.sol diff --git a/test/BatchAccessProfileTest.sol b/test/BatchAccessProfileTest.sol new file mode 100644 index 00000000..b706f596 --- /dev/null +++ b/test/BatchAccessProfileTest.sol @@ -0,0 +1,352 @@ +// SPDX-License-Identifier: AGPL-3.0 +pragma solidity ^0.8.0; + +import "../lib/forge-std/src/Test.sol"; +import "../src/Constants.sol"; +import "../src/Enums.sol"; +import "../src/Structs.sol"; + +import {Engine} from "../src/Engine.sol"; +import {SignedCommitManager} from "../src/commit-manager/SignedCommitManager.sol"; +import {SignedMatchmaker} from "../src/matchmaker/SignedMatchmaker.sol"; +import {BattleOfferLib} from "../src/matchmaker/BattleOfferLib.sol"; +import {StandardAttackFactory} from "../src/moves/StandardAttackFactory.sol"; +import {ATTACK_PARAMS} from "../src/moves/StandardAttackStructs.sol"; + +import {IEngine} from "../src/IEngine.sol"; +import {IEngineHook} from "../src/IEngineHook.sol"; +import {IEffect} from "../src/effects/IEffect.sol"; +import {IMoveSet} from "../src/moves/IMoveSet.sol"; +import {IRandomnessOracle} from "../src/rng/IRandomnessOracle.sol"; +import {IRuleset} from "../src/IRuleset.sol"; +import {IValidator} from "../src/IValidator.sol"; + +import {TypeCalculator} from "../src/types/TypeCalculator.sol"; +import {ITypeCalculator} from "../src/types/ITypeCalculator.sol"; + +import {BatchHelper} from "./abstract/BatchHelper.sol"; +import {TestTeamRegistry} from "./mocks/TestTeamRegistry.sol"; + +/// @notice Tallies SSTORE / SLOAD access patterns across an N-turn game, comparing legacy +/// per-turn execution vs single-tx batched execution.

Add `Engine.getStorageKey(bytes32) external view` so move managers can resolve a battleKey to the engine's storageKey (the one MappingAllocator recycles across battles via its free-list). 2. Re-key `SignedCommitManager.moveBuffer` and `bufferCounters` from battleKey to storageKey. Battle N+1 reuses the same buffer/counter slots as battle N (warm nonzero->nonzero SSTOREs ~2.9k instead of cold zero->nonzero ~22.1k). No new state in the manager — the engine's existing allocator does the slot recycling. Realistic-game access tally (`test_realisticGameAccessProfile_steadyState`, mirrors `InlineEngineGasTest.test_consecutiveBattleGas`'s 14-turn move sequence, measured on Battle 2 = steady state): | metric | legacy | batched | delta | |---------------|--------|---------|-------| | SSTOREs total | 145 | 174 | +29 | | - z->nz | 4 | 4 | 0 | <- no cold buffer writes | - nz->nz | 92 | 117 | +25 | <- submissions are warm | Cold SLOADs | 280 | 159 | -121 | <- amortization works | Warm SLOADs | 1499 | 1674 | +175 | Storage I/O gas (EIP-2929 prices): legacy: ~1119k batched: ~984k savings: ~135k per 14-turn game (~10k/turn, scales linearly) The cold-state +249k regression I reported earlier was an artifact of fresh battleKey-keyed slots costing 22k z->nz each on every battle. With storageKey-keyed buffer, steady-state batched is strictly cheaper than legacy in storage I/O — the SLOAD amortization across one tx outweighs the per-submission warm SSTORE overhead. 535 existing tests still pass; snapshots regress by ~300-1000 gas each from the added getStorageKey external view. https://claude.ai/code/session_01AWNvQmDFzSK7sYMDXtyXD5 --- snapshots/BetterCPUInlineGasTest.json | 12 +- snapshots/EngineGasTest.json | 36 +- snapshots/EngineOptimizationTest.json | 4 +- snapshots/FullyOptimizedInlineGasTest.json | 12 +- snapshots/InlineEngineGasTest.json | 28 +- snapshots/MatchmakerTest.json | 6 +- snapshots/StandardAttackPvPGasTest.json | 10 +- src/Engine.sol | 8 + src/IEngine.sol | 5 + src/commit-manager/SignedCommitManager.sol | 40 +- test/BatchAccessProfileRealisticTest.sol | 428 +++++++++++++++++++++ 11 files changed, 521 insertions(+), 68 deletions(-) create mode 100644 test/BatchAccessProfileRealisticTest.sol diff --git a/snapshots/BetterCPUInlineGasTest.json b/snapshots/BetterCPUInlineGasTest.json index 0d1a9747..8ee654d0 100644 --- a/snapshots/BetterCPUInlineGasTest.json +++ b/snapshots/BetterCPUInlineGasTest.json @@ -1,8 +1,8 @@ { -

The moveBuffer SSTORE is itself the on-chain observable; off-chain replay can index storage diffs. Saves a LOG3 per submission. #5 Replace ENGINE.getCommitContext() + ENGINE.getStorageKey() (2 external calls, ~5 SLOADs) with ENGINE.getSubmitContext() in submitTurnMoves. The new getter returns ONLY what async submission needs (p0, p1, turnId, winnerIndex, storageKey) in one call, with 3 SLOADs. Skips startTimestamp/validator/playerSwitchForTurnFlag reads — none are required at submission time in the batched flow. The non-existent-battle case is rejected via the existing winnerIndex != 2 check (default-zero BattleData fails it). #4 Re-pack BattleData so all per-turn-mutable fields live in slot 1. Slot 0 (p1, p0TeamIndex, p1TeamIndex) becomes immutable during play. Slot 1 absorbs turnId (shrunk uint64 -> uint16: 65k turns/battle is plenty) by shrinking lastExecuteTimestamp uint48 -> uint40 (year 36800 cap, still plenty). External getters keep their uint48/uint256 return types via implicit widening, so no ABI break for clients. Realistic-game access tally (steady state, 14-turn game from test_consecutiveBattleGas) - before -> after this commit: submission SLOADs (summed): 98 -> 56 (-42, mostly from skipping the BattleConfig SLOAD that getCommitContext does) batched cold SLOAD savings vs legacy: 121 -> 149 (-28 more cold reads amortized) batched SLOAD delta total: +25 -> +12 (much closer to legacy) batched SSTORE delta total: +29 -> +29 (unchanged - the buffer + counter SSTOREs are still the architectural floor) Net storage I/O savings vs legacy in steady state: ~135k -> ~223k (per 14-turn game), an extra ~88k from these three changes alone. All 536 tests pass (updated test_submitTurnMoves_nonExistentBattle_reverts to expect BattleAlreadyComplete instead of BattleNotYetStarted, since the getSubmitContext path no longer SLOADs startTimestamp; the default-zero winnerIndex on a non-existent battle still catches it). https://claude.ai/code/session_01AWNvQmDFzSK7sYMDXtyXD5 --- snapshots/BetterCPUInlineGasTest.json | 12 +++---- snapshots/EngineGasTest.json | 38 +++++++++++----------- snapshots/EngineOptimizationTest.json | 4 +-- snapshots/FullyOptimizedInlineGasTest.json | 12 +++---- snapshots/InlineEngineGasTest.json | 28 ++++++++-------- snapshots/MatchmakerTest.json | 6 ++-- snapshots/StandardAttackPvPGasTest.json | 10 +++--- src/Engine.sol | 24 +++++++++++++- src/IEngine.sol | 4 +++ src/Structs.sol | 17 +++++++--- src/commit-manager/SignedCommitManager.sol | 28 +++++++--------- test/BufferSubmissionTest.sol | 9 +++-- 12 files changed, 112 insertions(+), 80 deletions(-) diff --git a/snapshots/BetterCPUInlineGasTest.json b/snapshots/BetterCPUInlineGasTest.json index 8ee654d0..b222bf74 100644 --- a/snapshots/BetterCPUInlineGasTest.json +++ b/snapshots/BetterCPUInlineGasTest.json @@ -1,8 +1,8 @@ { -

Refactored callsites (all functionally identical when shadow inactive since the helpers fall straight through to direct SLOAD/SSTORE): _executeInternal: - start-of-turn winnerIndex check -> _getWinnerIndex - turnId read -> _getTurnId - prev/curr flag swap -> _setPrevPlayerSwitchForTurnFlag + _getPlayerSwitchForTurnFlag - single-player flag branch -> _getPlayerSwitchForTurnFlag once into local - end-of-turn 3-field write -> _setLastExecAndIncrementTurnId - final winnerIndex check -> _getWinnerIndex _checkAndSetWinnerIfGameOver: - winnerIndex read + write -> _getWinnerIndex / _setWinnerIndex _dealDamageInternal: - winnerIndex check -> _getWinnerIndex WIP remainder (still on storage refs, will be converted next): - `battle.activeMonIndex` reads (29 callsites — _unpackActiveMonIndex patterns throughout the engine) - `battle.activeMonIndex = ...` write in `_handleSwitch` - `battle.playerSwitchForTurnFlag = ...` write in `switchActiveMon` - `battle.winnerIndex` reads in `_checkForGameOverOrKO`, `_handleEffects` - `battle.turnId` reads in `_handleMove`, `_handleSwitch` Until those land, `executeBatchedTurns` cannot activate shadow safely (stale reads would break correctness).

Realistic 14-turn steady-state game (BatchAccessProfileRealisticTest): | metric | legacy | batched | delta | |----------------|--------|---------|-------| | SLOADs total | 2054 | 1261 | -793 | | - cold | 280 | 131 | -149 | | - warm | 1774 | 1130 | -644 | | SSTOREs total | 119 | 114 | -5 | | - nz->nz | 83 | 81 | -2 | Storage I/O cost: legacy ~1089k -> batched ~706k = save ~383k per 14-turn game (~27k/turn, ~35% reduction). Compared to previous baseline (before shadow refactor): +160k more savings on top of the existing ~223k advantage. Total batched storage I/O advantage now ~35% of legacy. Bonus: legacy SSTOREs dropped 145 -> 119 because `_setLastExecAndIncrementTurnId`'s explicit RMW coalesces the 3 end-of-turn slot-1 writes into one SSTORE more aggressively than Solidity's optimizer was previously achieving. All 536 tests pass. https://claude.ai/code/session_01AWNvQmDFzSK7sYMDXtyXD5 --- snapshots/BetterCPUInlineGasTest.json | 12 +- snapshots/EngineGasTest.json | 36 ++--- snapshots/EngineOptimizationTest.json | 4 +- snapshots/FullyOptimizedInlineGasTest.json | 12 +- snapshots/InlineEngineGasTest.json | 28 ++-- snapshots/MatchmakerTest.json | 6 +- snapshots/StandardAttackPvPGasTest.json | 10 +- src/Engine.sol | 162 ++++++++++++++++----- src/IEngine.sol | 3 + src/commit-manager/SignedCommitManager.sol | 49 +------ 10 files changed, 187 insertions(+), 135 deletions(-) diff --git a/snapshots/BetterCPUInlineGasTest.json b/snapshots/BetterCPUInlineGasTest.json index fe4eab43..6e07a74b 100644 --- a/snapshots/BetterCPUInlineGasTest.json +++ b/snapshots/BetterCPUInlineGasTest.json @@ -1,8 +1,8 @@ { -

From 2ceaa1e2a32a764e797664d66b5f2a15538f0cb0 Mon Sep 17 00:00:00 2001 From: Claude Date: Fri, 22 May 2026 07:58:56 +0000 Subject: [PATCH 13/65] shadow refactor: MonState shadow + steady-state harness for BatchGasTest MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Adds per-(player, monIndex) transient mirror for MonState so writes during executeBatchedTurns dedup across sub-turns (one SSTORE per dirty slot at batch end instead of one per turn). Mirrors the BattleData slot-1 shadow design: _readMonStatePacked / _writeMonStatePacked / _flushShadowMonStates plus _loadMonState / _storeMonState memory-pattern helpers used by all MonState mutation + read sites (_dealDamageInternal, _updateMonStateInternal, _handleMove stamina deduct, _inlineRegenStaminaForMon, _computePriorityPlayerIndex, _getDamageCalcContextInternal, _readMonStateDelta, getCPUContext, getMonStatesForSide, etc.). Drops the now-unused _getMonState / _deductStamina. Realistic 14-turn steady-state access tally: batched - legacy = -25 SSTOREs / -915 SLOADs (was -5 / -793 pre-MonState-shadow). Legacy gas snapshots regress ~5-8% from the unpack/repack overhead of the memory pattern in single-turn paths — documented in OPT_PLAN §12 as a known trade-off. BatchGasTest now runs a warmup battle (low HP) to completion before the measured battle so the measured battle reuses the freed storageKey (MappingAllocator steady state). The warmup uses the same flow as the measurement (legacy or batched) so manager buffer slots are also warm for the batched path. Asserts storageKey reuse before measuring. BatchAccessProfileRealisticTest adds the same storageKey-reuse precondition asserts for both legacy and batched battle pairs. --- OPT_PLAN.md | 7 + snapshots/BetterCPUInlineGasTest.json | 12 +- snapshots/EngineGasTest.json | 20 +-- snapshots/EngineOptimizationTest.json | 4 +- snapshots/FullyOptimizedInlineGasTest.json | 6 +- snapshots/InlineEngineGasTest.json | 16 +- snapshots/StandardAttackPvPGasTest.json | 10 +- src/Engine.sol | 163 ++++++++++++++------- test/BatchAccessProfileRealisticTest.sol | 19 ++- test/BatchGasTest.sol | 126 +++++++++++++++- 10 files changed, 295 insertions(+), 88 deletions(-) diff --git a/OPT_PLAN.md b/OPT_PLAN.md index 4718df81..e03793c3 100644 --- a/OPT_PLAN.md +++ b/OPT_PLAN.md @@ -584,3 +584,10 @@ Decisions made while executing the todo above. Each entry: short context + the c - **Multi-mon scenario interpretation.** §0.1 wording was "all four mons referenced via onUpdateMonState listeners on bench mons". Production engine doesn't actually touch bench mons during a regular turn — only the active mons on each side. The natural multi-slot turn is a switch turn where p0 switches mon 0→1 while p1 attacks (touches p0 mon 0, p0 mon 1, p1 mon 0 = three distinct mon-state slots). Implemented that interpretation; logs show 16 cold SLOADs / 16 unique slots — slightly fewer than a clean trade because no second-attack SSTORE pattern. - **Forced-switch entry point.** `_fastTurn` goes through `executeWithDualSignedMoves`, which reverts `NotTwoPlayerTurn()` once `playerSwitchForTurnFlag != 2`. Added a `_fastSinglePlayerTurn` helper that routes through `executeSinglePlayerMove(...)` with `vm.prank(actingPlayer)`. This is the same dispatch the production code does and matches what the batch flow will do via §6.1. +### Phase 1 (MonState shadow) + +- **MonState shadow added on top of slot-1 shadow.** Mirrored the BattleData slot-1 shadow design at the MonState level: per-(player, monIndex) packed value cached in transient, dirty-bit tracked in `_shadowMonStateDirty`, flushed once at end of `executeBatchedTurns` via `_flushShadowMonStates(storageKey)`. Read/write helpers `_loadMonState` / `_storeMonState` use the packed transient when shadow is active and fall back to SLOAD/SSTORE otherwise — same dispatch as `_readBattleSlot1Packed`. Refactored all in-engine MonState mutation sites (`_dealDamageInternal`, `_updateMonStateInternal`, `_handleMove`'s stamina deduct, `_inlineRegenStaminaForMon`) and read-only sites that need to observe in-flight shadow values (`_computePriorityPlayerIndex`, `_getDamageCalcContextInternal`, `_readMonStateDelta`, `getCPUContext`, `getMonStatesForSide`, etc.) to use the memory-pattern via the helpers. +- **Realistic-game access tally (steady state, 14 turns): batched - legacy = -25 SSTOREs / -915 SLOADs**, a step up from the pre-MonState-shadow baseline of -5 SSTOREs / -793 SLOADs. The MonState shadow specifically coalesces 18 additional `nz->nz` SSTOREs (stamina/hpDelta mutations across sub-turns dedup'd by the per-mon transient) and 122 additional warm SLOADs (reads now hit the transient mirror inside the batch). +- **Legacy-path overhead trade-off.** The memory pattern (`_loadMonState` returns a `MonState memory`, all 9 fields unpacked; `_storeMonState` takes a `MonState memory`, all 9 fields repacked) replaces what used to be storage-ref-with-direct-field-access in the single-turn path. Snapshot diffs show legacy gas tests regressed ~5-8% per scenario (e.g. `Inline_Execute` +20k = +5.6%, `Battle1_Execute` +31k = +6.4%, `ThirdBattle` +224k = +8.6%). The unpack/repack costs ~270 gas/call (mostly memory expansion + shift ops); a 14-turn legacy game does ~140 such calls = ~38k. Live-with-it cost; the batched flow gains ~70k per game from the dedup, so net for users running the batched path is positive. If the legacy regression proves unacceptable downstream, the mitigation is per-field `_readMonStateField` / `_writeMonStateField` helpers that bypass the full unpack/repack in non-shadow mode — kept as a follow-up. +- **Steady-state harness for `BatchGasTest`.** The microbench previously measured battle 1 with HP=100000 (no KOs ever), conflating "cold storage" with "first-touch" and not exercising the engine's `MappingAllocator` free-list. Added a `_runWarmupAndCapture(useBatchedFlow)` helper that drives a low-HP (HP=20) battle to completion via the same flow the measured battle will use (so manager buffer slots warm for batched, only engine slots warm for legacy), then asserts `engine.getStorageKey(warm) == engine.getStorageKey(measured)` before measurement. This matches the harness in `BatchAccessProfileRealisticTest`. Gas numbers from this microbench are still inflated for legacy because all calls share warm-storage within one foundry tx (production legacy = N separate txs, each fresh); the access-tally in the realistic test is the authoritative measure of cold/warm separation. + diff --git a/snapshots/BetterCPUInlineGasTest.json b/snapshots/BetterCPUInlineGasTest.json index 6e07a74b..8b0081b4 100644 --- a/snapshots/BetterCPUInlineGasTest.json +++ b/snapshots/BetterCPUInlineGasTest.json @@ -1,8 +1,8 @@ { - "Flag0_P0ForcedSwitch": "32527", - "Turn0_Lead": "131810", - "Turn1_BothAttack": "260254", - "Turn2_BothAttack": "234330", - "Turn3_BothAttack": "230354", - "Turn4_BothAttack": "230358" + "Flag0_P0ForcedSwitch": "35878", + "Turn0_Lead": "144953", + "Turn1_BothAttack": "288411", + "Turn2_BothAttack": "262487", + "Turn3_BothAttack": "258511", + "Turn4_BothAttack": "258515" } \ No newline at end of file diff --git a/snapshots/EngineGasTest.json b/snapshots/EngineGasTest.json index 81352aad..5a1375ef 100644 --- a/snapshots/EngineGasTest.json +++ b/snapshots/EngineGasTest.json @@ -1,21 +1,21 @@ { - "B1_Execute": "981697", + "B1_Execute": "1034154", "B1_Setup": "851407", - "B2_Execute": "728994", - "B2_Setup": "308112", - "Battle1_Execute": "479300", + "B2_Execute": "780307", + "B2_Setup": "309146", + "Battle1_Execute": "510136", "Battle1_Setup": "826611", - "Battle2_Execute": "400591", + "Battle2_Execute": "431345", "Battle2_Setup": "245936", - "External_Execute": "489906", + "External_Execute": "520742", "External_Setup": "817345", - "FirstBattle": "3221254", - "Inline_Execute": "356081", + "FirstBattle": "3445478", + "Inline_Execute": "376749", "Inline_Setup": "227877", "Intermediary stuff": "45490", - "SecondBattle": "3272518", + "SecondBattle": "3517117", "Setup 1": "1713123", "Setup 2": "312999", "Setup 3": "354329", - "ThirdBattle": "2593870" + "ThirdBattle": "2817530" } \ No newline at end of file diff --git a/snapshots/EngineOptimizationTest.json b/snapshots/EngineOptimizationTest.json index c27d9d2c..afae2f2f 100644 --- a/snapshots/EngineOptimizationTest.json +++ b/snapshots/EngineOptimizationTest.json @@ -1,4 +1,4 @@ { - "ExternalStaminaRegen": "423222", - "InlineStaminaRegen": "1097936" + "ExternalStaminaRegen": "464950", + "InlineStaminaRegen": "1153729" } \ No newline at end of file diff --git a/snapshots/FullyOptimizedInlineGasTest.json b/snapshots/FullyOptimizedInlineGasTest.json index 3820258a..7546ef8b 100644 --- a/snapshots/FullyOptimizedInlineGasTest.json +++ b/snapshots/FullyOptimizedInlineGasTest.json @@ -1,7 +1,7 @@ { - "Fast_Battle1": "2165088", - "Fast_Battle2": "2073522", - "Fast_Battle3": "1584449", + "Fast_Battle1": "2326325", + "Fast_Battle2": "2245746", + "Fast_Battle3": "1745326", "Fast_Setup_1": "1346535", "Fast_Setup_2": "219808", "Fast_Setup_3": "216011" diff --git a/snapshots/InlineEngineGasTest.json b/snapshots/InlineEngineGasTest.json index ebcc3375..bd5f566d 100644 --- a/snapshots/InlineEngineGasTest.json +++ b/snapshots/InlineEngineGasTest.json @@ -1,16 +1,16 @@ { - "B1_Execute": "971656", + "B1_Execute": "1011602", "B1_Setup": "783412", - "B2_Execute": "696460", - "B2_Setup": "287145", - "Battle1_Execute": "436724", + "B2_Execute": "735306", + "B2_Setup": "288179", + "Battle1_Execute": "457430", "Battle1_Setup": "758608", - "Battle2_Execute": "356021", + "Battle2_Execute": "376689", "Battle2_Setup": "227205", - "FirstBattle": "2905108", - "SecondBattle": "2917446", + "FirstBattle": "3068996", + "SecondBattle": "3096212", "Setup 1": "1637244", "Setup 2": "322179", "Setup 3": "318385", - "ThirdBattle": "2277807" + "ThirdBattle": "2441329" } \ No newline at end of file diff --git a/snapshots/StandardAttackPvPGasTest.json b/snapshots/StandardAttackPvPGasTest.json index 7c2f8cdc..7f3d04dc 100644 --- a/snapshots/StandardAttackPvPGasTest.json +++ b/snapshots/StandardAttackPvPGasTest.json @@ -1,7 +1,7 @@ { - "Turn0_Lead": "97635", - "Turn1_BothAttack": "135501", - "Turn2_BothAttack": "95706", - "Turn3_BothAttack": "95751", - "Turn4_BothAttack": "95761" + "Turn0_Lead": "111691", + "Turn1_BothAttack": "153939", + "Turn2_BothAttack": "114144", + "Turn3_BothAttack": "114189", + "Turn4_BothAttack": "114199" } \ No newline at end of file diff --git a/src/Engine.sol b/src/Engine.sol index 721e87e0..4da696c5 100644 --- a/src/Engine.sol +++ b/src/Engine.sol @@ -447,6 +447,9 @@ contract Engine is IEngine, MappingAllocator { // Flush the deferred slot-1 write back to storage exactly once, even if we executed N turns. _flushShadowBattleSlot1(battleKey);

Of these, only koBitmaps mutates frequently mid-batch (one write per KO; the realistic 14-turn steady-state game shows ~5-6 of the 10 BC.slot2 writes are koBitmaps). Shadow JUST the koBitmaps uint16 into a transient (not the whole slot), so reads of immutable slot-2 fields stay as direct SLOADs in legacy mode -- no TLOAD-check overhead on every moveManager / teamSizes / startTimestamp access. New helpers: _readKoBitmaps (shadow-aware read), _loadShadowKoBitmaps (lazy SLOAD-into-transient on first write), _writeKoBitmaps, _flushShadowKoBitmaps. Refactor _getKOBitmap, _setMonKO, _clearMonKO to route through them. Other field writes during the batch (globalKVCount bump, etc.) keep doing direct SSTORE; the flush at end-of-batch overwrites only the koBitmaps bits in storage so the shadowed value wins. Flush is unconditional -- koBitmaps is part of public API (getKOBitmap, getBattleEndContext, getCPUContext) and the OnBattleEnd hook fires in the same tx for game-ending batches, so storage must be coherent before executeBatchedTurns returns. Realistic 14-turn steady-state delta: batched - legacy = -35 SSTOREs / -936 SLOADs (was -31 / -915 after the game-over flush skip). ~4 fewer SSTOREs from koBit coalescing (~12k gas), ~21 fewer SLOADs from cached-after-first-load reads. Legacy gas snapshots regress ~500 gas per game (~0.1%) from the narrow TLOAD checks. Diagnostic test reads koBitmaps via raw slot 2 load -- the engine's getKOBitmap(battleKey) returns 0 post-game-over due to a pre-existing artifact where _freeStorageKey deletes the battleKey -> storageKey mapping, so getBattle(battleKey) reads an empty config row (already documented at the BattleConfigView builder in getBattle). --- snapshots/EngineGasTest.json | 18 ++--- snapshots/FullyOptimizedInlineGasTest.json | 6 +- snapshots/InlineEngineGasTest.json | 14 ++-- src/Engine.sol | 80 ++++++++++++++++++++-- test/BatchAccessProfileRealisticTest.sol | 9 ++- 5 files changed, 99 insertions(+), 28 deletions(-) diff --git a/snapshots/EngineGasTest.json b/snapshots/EngineGasTest.json index 5a1375ef..10cb6637 100644 --- a/snapshots/EngineGasTest.json +++ b/snapshots/EngineGasTest.json @@ -1,21 +1,21 @@ { - "B1_Execute": "1034154", + "B1_Execute": "1034651", "B1_Setup": "851407", - "B2_Execute": "780307", + "B2_Execute": "780804", "B2_Setup": "309146", - "Battle1_Execute": "510136", + "Battle1_Execute": "510633", "Battle1_Setup": "826611", - "Battle2_Execute": "431345", + "Battle2_Execute": "431842", "Battle2_Setup": "245936", - "External_Execute": "520742", + "External_Execute": "521239", "External_Setup": "817345", - "FirstBattle": "3445478", - "Inline_Execute": "376749", + "FirstBattle": "3449447", + "Inline_Execute": "377246", "Inline_Setup": "227877", "Intermediary stuff": "45490", - "SecondBattle": "3517117", + "SecondBattle": "3521122", "Setup 1": "1713123", "Setup 2": "312999", "Setup 3": "354329", - "ThirdBattle": "2817530" + "ThirdBattle": "2821499" } \ No newline at end of file diff --git a/snapshots/FullyOptimizedInlineGasTest.json b/snapshots/FullyOptimizedInlineGasTest.json index 7546ef8b..785d4fe4 100644 --- a/snapshots/FullyOptimizedInlineGasTest.json +++ b/snapshots/FullyOptimizedInlineGasTest.json @@ -1,7 +1,7 @@ { - "Fast_Battle1": "2326325", - "Fast_Battle2": "2245746", - "Fast_Battle3": "1745326", + "Fast_Battle1": "2330294", + "Fast_Battle2": "2249751", + "Fast_Battle3": "1749295", "Fast_Setup_1": "1346535", "Fast_Setup_2": "219808", "Fast_Setup_3": "216011" diff --git a/snapshots/InlineEngineGasTest.json b/snapshots/InlineEngineGasTest.json index bd5f566d..e681cd56 100644 --- a/snapshots/InlineEngineGasTest.json +++ b/snapshots/InlineEngineGasTest.json @@ -1,16 +1,16 @@ { - "B1_Execute": "1011602", + "B1_Execute": "1012099", "B1_Setup": "783412", - "B2_Execute": "735306", + "B2_Execute": "735803", "B2_Setup": "288179", - "Battle1_Execute": "457430", + "Battle1_Execute": "457927", "Battle1_Setup": "758608", - "Battle2_Execute": "376689", + "Battle2_Execute": "377186", "Battle2_Setup": "227205", - "FirstBattle": "3068996", - "SecondBattle": "3096212", + "FirstBattle": "3072965", + "SecondBattle": "3100217", "Setup 1": "1637244", "Setup 2": "322179", "Setup 3": "318385", - "ThirdBattle": "2441329" + "ThirdBattle": "2445298" } \ No newline at end of file diff --git a/src/Engine.sol b/src/Engine.sol index 00f32f94..d2b56904 100644 --- a/src/Engine.sol +++ b/src/Engine.sol @@ -74,6 +74,11 @@ contract Engine is IEngine, MappingAllocator { uint256 private transient _shadowMonStateDirty; uint256 private constant _T_MONSTATE_BASE = 0x100000; + // koBitmaps shadow (narrow — just the 16-bit field within BC.slot2; see `_setMonKO`). + uint16 private transient _shadowKoBitmaps; + bool private transient _shadowKoBitmapsLoaded; + bool private transient _shadowKoBitmapsDirty; + // Errors error NoWriteAllowed(); error WrongCaller(); @@ -448,6 +453,10 @@ contract Engine is IEngine, MappingAllocator { // Flush the deferred slot-1 write back to storage exactly once, even if we executed N turns. // BD.slot1 must always flush — `getWinner` reads it directly post-batch. _flushShadowBattleSlot1(battleKey); + // Flush the shadowed koBitmaps too — same rule: `getKOBitmap`, `getBattleEndContext`, and + // the OnBattleEnd hook (fires in this same tx for game-ending batches) all read it + // directly from storage. + _flushShadowKoBitmaps(storageKey); // MonState flush is skipped on game-over: the next `startBattle` at this storageKey runs // the sentinel-clear loop which overwrites every prior slot anyway, so the un-flushed // values are recycled either way.

Each entry: short context + the c - **Legacy-path overhead trade-off.** The memory pattern (`_loadMonState` returns a `MonState memory`, all 9 fields unpacked; `_storeMonState` takes a `MonState memory`, all 9 fields repacked) replaces what used to be storage-ref-with-direct-field-access in the single-turn path. Snapshot diffs show legacy gas tests regressed ~5-8% per scenario (e.g. `Inline_Execute` +20k = +5.6%, `Battle1_Execute` +31k = +6.4%, `ThirdBattle` +224k = +8.6%). The unpack/repack costs ~270 gas/call (mostly memory expansion + shift ops); a 14-turn legacy game does ~140 such calls = ~38k. Live-with-it cost; the batched flow gains ~70k per game from the dedup, so net for users running the batched path is positive. If the legacy regression proves unacceptable downstream, the mitigation is per-field `_readMonStateField` / `_writeMonStateField` helpers that bypass the full unpack/repack in non-shadow mode — kept as a follow-up. - **Steady-state harness for `BatchGasTest`.** The microbench previously measured battle 1 with HP=100000 (no KOs ever), conflating "cold storage" with "first-touch" and not exercising the engine's `MappingAllocator` free-list. Added a `_runWarmupAndCapture(useBatchedFlow)` helper that drives a low-HP (HP=20) battle to completion via the same flow the measured battle will use (so manager buffer slots warm for batched, only engine slots warm for legacy), then asserts `engine.getStorageKey(warm) == engine.getStorageKey(measured)` before measurement. This matches the harness in `BatchAccessProfileRealisticTest`. Gas numbers from this microbench are still inflated for legacy because all calls share warm-storage within one foundry tx (production legacy = N separate txs, each fresh); the access-tally in the realistic test is the authoritative measure of cold/warm separation. +### Phase 1 (post-MonState follow-ups) + +- **Slot-bucket diagnostic in `BatchAccessProfileRealisticTest.test_realisticGameSlotBuckets`.** After BD.slot1 + MonState shadows the batched execute still touched 82 unique slots / 61 SSTOREs / 1021 SLOADs. Added a hash-anchored bucket helper that labels each accessed storage slot by its Engine region (BD.slotN, BC.slotN, MonState per-mon, Effects p0/p1/global, GlobalKV, etc.) so the remaining hot slots are visible at a glance. Top-write region was `BC.slot2` (KO bitmap + moveManager + teamSizes + startTs etc.) at 10 SSTOREs/game from KO-bit accumulation. +- **Step A: skip MonState flush on game-over.** When `executeBatchedTurns` exits with `winner != 0`, the next `startBattle` at this storageKey runs the sentinel-clear loop that overwrites every prior MonState slot anyway, so the un-flushed transient values are recycled either way. Wrapped `_flushShadowMonStates` in an `if (winner == address(0))` and explicitly clears `_shadowMonStateLoaded` / `_shadowMonStateDirty` in the skip path (otherwise a subsequent `executeBatchedTurns` in the same tx — multicall, or any foundry test — reads stale TLOAD bits from this batch and the game state diverges). BD.slot1 flushes unconditionally so `getWinner` stays correct. Saves 6 SSTOREs/game (the 4 + 2 dirty MonState slots at game-end). Trade-off: `getMonStateForBattle` returns stale values in the gap between batch-end and the next `startBattle`; user accepted (off-chain consumers replay from the move buffer). +- **Step B: narrow koBitmaps shadow.** `BC.slot2` packs 8 fields but only `koBitmaps` (uint16) mutates frequently mid-batch (one write per KO). Shadow just that 16-bit field — not the whole slot — into a dedicated transient (`_shadowKoBitmaps` + `_shadowKoBitmapsLoaded` + `_shadowKoBitmapsDirty`) so reads of immutable BC.slot2 fields (`moveManager`, `teamSizes`, `startTimestamp`, ...) stay as direct SLOADs and don't pay a TLOAD-check in legacy mode. Other field writes during the batch (e.g., `globalKVCount` bump) keep doing direct SSTORE; the unconditional flush at end-of-batch overwrites only the koBitmaps bits in storage so the shadowed value wins. Saves another 4 SSTOREs + 21 SLOADs per game (~12k gas). Legacy snapshot regression ~500 gas per game (0.1%) — small because the helper TLOAD-check is only on the koBit hot path, not on every BC.slot2 field read. +- **Final realistic-game steady-state delta: batched - legacy = -35 SSTOREs / -936 SLOADs** (from -25 / -915 after MonState shadow).

That was wrong — re-reading EIP-2200/2929, no-op SSTOREs (`prev == new`) cost only 100 gas warm / 2200 gas cold, not the ~2900 of an `nz->nz`. Actual savings ~2.1k gas/game. Not worth the complexity. + - **BC.slot0 / BC.slot1 shadow (effect counts).** Slots 0/1 pack `validator + packedP0EffectsCount` and `rngOracle + packedP1EffectsCount`. 7 writes/game (effect adds) vs 197 reads/game (every effect-list iteration consults the count). To make writes shadow-safe, reads must route through the shadow too (otherwise mid-batch reads see stale counts). At ~110 gas/TLOAD-check × 197 reads = ~22k legacy regression vs ~14k batched savings. Net negative. +- **Diminishing returns going forward.** The remaining hot slots are effect mappings (`p0Effects[mon][eff].slot0/slot1` reads) — already amortized via warm-slot caching within the single `executeBuffered` tx. The next real lever would be a structural change: a per-batch cached `EffectInstance` array in transient (read all live effects once into memory, iterate from memory across sub-turns, flush deltas at end).

Saves 1 ecrecover (~3k gas) + 1 sig in calldata (~1.1k @ 16 gas/byte) per turn on BOTH legacy (executeWithDualSignedMoves) and batched (submitTurnMoves) paths. The unilateral-revealer attack (where a revealer picks any preimage and signs keccak(P*) as the committer's hash) is closed by the msg.sender == committer check: only the actual committer can publish their own move. Trade-off: loses the "anyone can publish with both sigs" relayer capability for the committer side. Each turn, the player who is the committer-this-turn (parity) must submit themselves. Revealer doesn't need to be online at submit time (their sig is included in the committer's submission). Updates so far: - Structs.sol: TurnSubmission drops committerSig field - SignedCommitManager.sol: executeWithDualSignedMoves and submitTurnMoves drop committer sig param + verification, add msg.sender == committer check - BatchHelper.sol: _buildTurnSubmission returns (entry, committerAddr) so callers can vm.prank; _submitTurnMoves wraps the call in vm.prank - BufferSubmissionTest: rewrote relayer-can-submit (now must revert), removed wrong-committer-sig test (no committer sig now), kept revealer-side checks - 5 batched-flow tests: dropped cSig arg, added vm.prank(committer) before call Remaining: SignedCommitManager.t.sol (~18 call sites), InlineEngineGasTest, SignedCommitManagerGasBenchmark, StandardAttackPvPGasTest still need the same mechanical update. Several tests in SignedCommitManager.t.sol verify the committer-sig model specifically (wrongCommitter, replayAcrossBattle via sig recovery, etc.) -- those need rethinking, not just mechanical replacement. --- src/Structs.sol | 9 ++- src/commit-manager/SignedCommitManager.sol | 57 ++++++---------- test/BatchAccessProfileRealisticTest.sol | 4 +- test/BatchAccessProfileTest.sol | 4 +- test/BatchEdgeTest.sol | 8 +-- test/BatchEquivalenceTest.sol | 4 +- test/BatchGasTest.sol | 20 +++--- test/BatchInstrumentationTest.sol | 4 +- test/BufferSubmissionTest.sol | 75 +++++++++------------- test/SignedCommitManager.t.sol | 7 +- test/abstract/BatchHelper.sol | 11 ++-- 11 files changed, 86 insertions(+), 117 deletions(-) diff --git a/src/Structs.sol b/src/Structs.sol index d3df11af..36a40d4e 100644 --- a/src/Structs.sol +++ b/src/Structs.sol @@ -249,15 +249,18 @@ struct RevealedMove { // revealer) → (p0, p1) mapping happens at submission time based on `turnId % 2`. struct TurnSubmission { uint64 turnId; - // Committer preimage (revealed in the same tx as submission, signed by committer over moveHash). + // Committer preimage.

The committer is now identified by msg.sender at call time. The unilateral-revealer attack (revealer picks any preimage and signs keccak(P*) as the committer's hash) is closed by the msg.sender == committer check: only the actual committer can publish their own move with their own preimage. Trade-off: loses "anyone can publish with both sigs" for the committer side. Each turn, whichever player is the committer-by-parity must submit themselves. The revealer side still signs off-chain so they don't need to be online at submit time. Per-turn savings (verified on the realistic 14-turn steady-state game): Legacy (14 separate executeWithDualSignedMoves calls): before: 1,992,441 gas -> after: 1,940,018 gas (-52,423, ~3.7k/turn) Batched submit (14 submitTurnMoves): before: 283,289 gas -> after: 194,977 gas (-88,312, ~6.3k/submit) Batched total: before: 2,121,570 gas -> after: 2,033,280 gas (-88,290) Production estimate (each turn as its own tx; legacy assumes cold start per tx via cold-SLOAD penalty add-back): batched saves ~426k vs legacy production (~15.5% per 14-turn game), up from ~390k (14%) before. Storage I/O is unchanged (-35 SSTOREs / -936 SLOADs vs legacy in the access tally); savings are pure compute (1 fewer ecrecover, less keccak for the SignedCommit struct hash) + ~70 bytes less calldata per call (~1.1k @ 16 gas/byte).

The IR optimizer + via_ir already inlines internal function calls aggressively, so fusing only saves the small amount of redundant stack-frame setup the optimizer couldn't fold. Still above the 5k keep-threshold I set. Legacy executeWithDualSignedMoves gets the same savings since _executeInternal is shared. AfterMove block (player-effects + global-effects pair, runs twice per turn) NOT fused -- different shape (2 calls vs 3) and includes the _inlineStaminaRegen call between them, so a clean fusion is more invasive for less payoff. --- snapshots/BetterCPUInlineGasTest.json | 12 +- snapshots/EngineGasTest.json | 18 +-- snapshots/EngineOptimizationTest.json | 4 +- snapshots/FullyOptimizedInlineGasTest.json | 6 +- snapshots/InlineEngineGasTest.json | 14 +- snapshots/StandardAttackPvPGasTest.json | 10 +- src/Engine.sol | 142 +++++++++++---------- 7 files changed, 108 insertions(+), 98 deletions(-) diff --git a/snapshots/BetterCPUInlineGasTest.json b/snapshots/BetterCPUInlineGasTest.json index 8b0081b4..156c9986 100644 --- a/snapshots/BetterCPUInlineGasTest.json +++ b/snapshots/BetterCPUInlineGasTest.json @@ -1,8 +1,8 @@ { - "Flag0_P0ForcedSwitch": "35878", - "Turn0_Lead": "144953", - "Turn1_BothAttack": "288411", - "Turn2_BothAttack": "262487", - "Turn3_BothAttack": "258511", - "Turn4_BothAttack": "258515" + "Flag0_P0ForcedSwitch": "36710", + "Turn0_Lead": "146370", + "Turn1_BothAttack": "289821", + "Turn2_BothAttack": "263897", + "Turn3_BothAttack": "259921", + "Turn4_BothAttack": "259925" } \ No newline at end of file diff --git a/snapshots/EngineGasTest.json b/snapshots/EngineGasTest.json index 10cb6637..eafb1040 100644 --- a/snapshots/EngineGasTest.json +++ b/snapshots/EngineGasTest.json @@ -1,21 +1,21 @@ { - "B1_Execute": "1034651", + "B1_Execute": "1039285", "B1_Setup": "851407", - "B2_Execute": "780804", + "B2_Execute": "785438", "B2_Setup": "309146", - "Battle1_Execute": "510633", + "Battle1_Execute": "512916", "Battle1_Setup": "826611", - "Battle2_Execute": "431842", + "Battle2_Execute": "434125", "Battle2_Setup": "245936", - "External_Execute": "521239", + "External_Execute": "523522", "External_Setup": "817345", - "FirstBattle": "3449447", - "Inline_Execute": "377246", + "FirstBattle": "3471221", + "Inline_Execute": "379529", "Inline_Setup": "227877", "Intermediary stuff": "45490", - "SecondBattle": "3521122", + "SecondBattle": "3544429", "Setup 1": "1713123", "Setup 2": "312999", "Setup 3": "354329", - "ThirdBattle": "2821499" + "ThirdBattle": "2843273" } \ No newline at end of file diff --git a/snapshots/EngineOptimizationTest.json b/snapshots/EngineOptimizationTest.json index afae2f2f..470bbb53 100644 --- a/snapshots/EngineOptimizationTest.json +++ b/snapshots/EngineOptimizationTest.json @@ -1,4 +1,4 @@ { - "ExternalStaminaRegen": "464950", - "InlineStaminaRegen": "1153729" + "ExternalStaminaRegen": "468180", + "InlineStaminaRegen": "1158581" } \ No newline at end of file diff --git a/snapshots/FullyOptimizedInlineGasTest.json b/snapshots/FullyOptimizedInlineGasTest.json index 7a2e87eb..c605ad0b 100644 --- a/snapshots/FullyOptimizedInlineGasTest.json +++ b/snapshots/FullyOptimizedInlineGasTest.json @@ -1,7 +1,7 @@ { - "Fast_Battle1": "2288492", - "Fast_Battle2": "2203625", - "Fast_Battle3": "1707483", + "Fast_Battle1": "2308488", + "Fast_Battle2": "2224981", + "Fast_Battle3": "1727479", "Fast_Setup_1": "1346581", "Fast_Setup_2": "219602", "Fast_Setup_3": "216058" diff --git a/snapshots/InlineEngineGasTest.json b/snapshots/InlineEngineGasTest.json index e681cd56..fa13f0f3 100644 --- a/snapshots/InlineEngineGasTest.json +++ b/snapshots/InlineEngineGasTest.json @@ -1,16 +1,16 @@ { - "B1_Execute": "1012099", + "B1_Execute": "1016733", "B1_Setup": "783412", - "B2_Execute": "735803", + "B2_Execute": "740437", "B2_Setup": "288179", - "Battle1_Execute": "457927", + "Battle1_Execute": "460210", "Battle1_Setup": "758608", - "Battle2_Execute": "377186", + "Battle2_Execute": "379469", "Battle2_Setup": "227205", - "FirstBattle": "3072965", - "SecondBattle": "3100217", + "FirstBattle": "3094739", + "SecondBattle": "3123524", "Setup 1": "1637244", "Setup 2": "322179", "Setup 3": "318385", - "ThirdBattle": "2445298" + "ThirdBattle": "2467072" } \ No newline at end of file diff --git a/snapshots/StandardAttackPvPGasTest.json b/snapshots/StandardAttackPvPGasTest.json index d5ee1893..c9a5712f 100644 --- a/snapshots/StandardAttackPvPGasTest.json +++ b/snapshots/StandardAttackPvPGasTest.json @@ -1,7 +1,7 @@ { - "Turn0_Lead": "107447", - "Turn1_BothAttack": "149699", - "Turn2_BothAttack": "109919", - "Turn3_BothAttack": "109949", - "Turn4_BothAttack": "109977" + "Turn0_Lead": "108881", + "Turn1_BothAttack": "151126", + "Turn2_BothAttack": "111346", + "Turn3_BothAttack": "111376", + "Turn4_BothAttack": "111404" } \ No newline at end of file diff --git a/src/Engine.sol b/src/Engine.sol index 52d091bc..b6dc1916 100644 --- a/src/Engine.sol +++ b/src/Engine.sol @@ -718,39 +718,12 @@ contract Engine is IEngine, MappingAllocator { uint256 otherPlayerIndex = 1 - priorityPlayerIndex;

To make writes shadow-safe, reads must route through the shadow too (otherwise mid-batch reads see stale counts). At ~110 gas/TLOAD-check × 197 reads = ~22k legacy regression vs ~14k batched savings. Net negative. - **Diminishing returns going forward.** The remaining hot slots are effect mappings (`p0Effects[mon][eff].slot0/slot1` reads) — already amortized via warm-slot caching within the single `executeBuffered` tx. The next real lever would be a structural change: a per-batch cached `EffectInstance` array in transient (read all live effects once into memory, iterate from memory across sub-turns, flush deltas at end). That's a much bigger refactor than the field-level shadows above; queued for a future tier if a profile of an effect-heavy game shows it's worth it. +### Phase 1 (single-sig + compute-side trace) + +- **Drop committer signature in dual-signed flows.** `executeWithDualSignedMoves` and `submitTurnMoves` now identify the committer by `msg.sender` instead of by an explicit signature. The unilateral-revealer attack (revealer picks any preimage P*, signs `keccak(P*)` as the committer's hash) is closed by `msg.sender == committer`. Trade-off: loses the "anyone can publish with both sigs" relayer property for the committer side (the revealer's sig still lets them be offline at submit time). Per-turn savings on the realistic 14-turn steady-state game: legacy ~3.7k/turn (~52k/game), batched ~6.3k/submit (~88k/game). Production batched-vs-legacy gap widens from ~390k to ~426k (~15.5% per game). + +- **Deep gas trace via per-region instrumentation.** Added temporary `GasProfile` event with 14 per-region transient counters accumulated across the 14-turn batched flow. Emitted at end of `executeBatchedTurns`. Findings: effects dispatch (RoundStart + AfterMove × 4 + RoundEnd) = **47% (843k of 1.86M)**, `_handleMove` = **35% (628k)**, framework overhead (decode + reset + flush) = **2% (37k)**. Compute-side is at or near the floor for the existing game semantics — the remaining costs are real game work (damage calc, type lookup, effect contract calls). + +- **`_handleEffectsTriple` fusion.** RoundStart and RoundEnd each call `_handleEffects` three times (global + priority-mon + other-mon). Fused into a single function frame with identical semantics. Saved ~7k/game (~3.4k each on R3 + R8). Smaller than estimated because IR optimizer + via_ir already inlines internal calls aggressively; the win is just the redundant stack-frame setup the optimizer couldn't fold. AfterMove's 2-call pattern (per-mon + global, interleaved with `_inlineStaminaRegen`) NOT fused — different shape, less payoff. + +- **Skipped: per-turn active-mon-index cache.** Active mon index changes mid-turn (switch moves call `_setActiveMonIndexPacked`; future Roar-style effects could too). Caching it across a turn breaks correctness. Adjacent-line coalescing (where no state can change between back-to-back `_getActiveMonIndex` reads) is safe but only saves ~3-7k/game — below the keep threshold for the bytecode/complexity cost. + +- **Skipped: preload effects into memory array.** Theoretical max savings ~30-40k/game (replace 402 warm-SLOAD effect reads with memory reads). Implementation requires write-through to a memory cache from `addEffect` / `removeEffect` / `_updateOrRemoveEffect` to maintain coherency, plus a sparse memory layout to avoid 50KB+ memory-expansion costs on the cache structure. Complexity-to-savings ratio doesn't pencil — the cached reads are already warm SLOADs (100 gas), and the population/maintenance cost ate most of the win in back-of-envelope.

From d7689e312ed1c1f8ee3a83d7e95607dca5b0c783 Mon Sep 17 00:00:00 2001 From: Claude Date: Sat, 23 May 2026 02:15:08 +0000 Subject: [PATCH 27/65] opt: drop per-turn events + hoist constant config fields from _executeInternal Four batch-friendly structural cleanups in one go, totaling ~68k saved per 14-turn batched game (~3.4% of executeBuffered): (1) Drop MonMoves event emission per turn (~28k). Off-chain consumers reconstruct per-turn moves from the manager-side moveBuffer SSTOREs (batched) or from the executeWith* calldata (legacy). No event needed in either case. The _emitMonMoves helper + the MonMoves event definition are removed. (2) Drop EngineExecute event emission per turn (~10k). The manager already emits TurnsExecuted(battleKey, startTurnId, executedCount, winner) once per batched call, which strictly subsumes per-turn EngineExecute. For legacy, the executeWithDualSignedMoves / executeWithMoves tx itself is the on-chain event. (3) Hoist battleKeyForWrite assignment from _executeInternal to entry points (~1.4k). In batched mode the value is set once before the loop instead of N times inside _executeInternal -- saves N-1 TSTOREs. For legacy entry points the cost is unchanged (one set per call). (4) Hoist numHooks + hasInlineStaminaRegen reads from _executeInternal to the caller, threading them through as function params (~3-5k). Both fields live in BC.slot2 and are constant for a battle's lifetime; reading once per batch instead of once per turn saves ~13 warm SLOADs. Realistic 14-turn steady-state delta vs prior commit (94cf55d post-fuse): LEGACY total : 1,933,178 -> 1,867,567 (-65,611, ~3.4%) BATCHED execute : 1,831,339 -> 1,762,241 (-69,098, ~3.8%) BATCHED total : 2,026,152 -> 1,957,203 (-68,949, ~3.4%) Production saves vs L : 427,026 -> 430,364 (+3,338 widening) Access tally now shows -906 SLOADs (was -934): the difference is the ~28 _getActiveMonIndex reads inside _emitMonMoves that no longer fire.

Approximately 100k gas saved on SSTOREs + 94k saved on SLOADs = ~200k batched advantage per 14-turn game vs the legacy baseline. Per-slot proof of shadow batching: BD.slot1 14 writes → 1 (single flush), BC.slot2 koBitmaps ~5 writes → 0 (folded into one already-needed slot write), MonStates ~6 writes → 0 (game-over flush skip). > **HARNESS BIAS — important for reading the gas-measurement counterpart `test_realisticGameSteadyStateGas`.** `gasleft()` inside a single foundry test function measures all 14 legacy turns under ONE EVM transaction. Per EIP-2929 slots accessed in turn 1 become warm for turns 2-14 (SLOAD 100 instead of 2,100; SSTORE doesn't pay the cold-access penalty). In production each legacy turn is its own tx with cold-start access. Within-tx-warm measurement gives legacy ~1.99M / batched ~2.12M (batched looks +6.5% worse). Production estimate (adding ~260 cold-SLOAD penalties + 14× intrinsic tx cost): legacy ~2.81M / batched ~2.12M (batched saves ~390k, ~14%). The access-tally test is the authoritative steady-state production measure — it records each turn's state diff under its own per-call recording, so cold/warm classification is production-accurate. **Trust the SSTORE/SLOAD count delta, not the single-tx gasleft() number.** -- **Stopped here.** Two further candidates were measured and rejected: +- **Stopped here.** Three further candidates were measured and rejected: - **Effect-data no-op write guard.** Initial diagnostic flagged 21 effect-data no-op SSTOREs per game; I sized this at ~46k gas savings. That was wrong — re-reading EIP-2200/2929, no-op SSTOREs (`prev == new`) cost only 100 gas warm / 2200 gas cold, not the ~2900 of an `nz->nz`. Actual savings ~2.1k gas/game. Not worth the complexity. - **BC.slot0 / BC.slot1 shadow (effect counts).** Slots 0/1 pack `validator + packedP0EffectsCount` and `rngOracle + packedP1EffectsCount`. 7 writes/game (effect adds) vs 197 reads/game (every effect-list iteration consults the count). To make writes shadow-safe, reads must route through the shadow too (otherwise mid-batch reads see stale counts). At ~110 gas/TLOAD-check × 197 reads = ~22k legacy regression vs ~14k batched savings. Net negative. + - **Effect-data slot shadow (full transient mirror per effect lane).** Hypothesis: per-mon effect data slots get written multiple times per batch (counter bumps in ALWAYS_APPLIES effects, status-degree updates). Implemented a transient `_shadowEffectData[player][mon][slot]` mirror with a per-lane dirty bitmap, routed all `p[01]EffectsData` reads/writes through `_loadEffectDataSlot` / `_storeEffectDataSlot`, and flushed dirty lanes at end-of-batch. Realistic 14-turn steady state moved 292 SLOADs (warm, ~29k) and 21 no-op SSTOREs (~2k) into transient — total measurable storage savings ~31k. But the per-iteration TLOAD-check on `_isEffectLaneDirty` (paid every effect read regardless of shadow state) added ~190k of overhead, and the legacy single-tx harness regressed from 1,867,567 → 1,914,298 (+47k), batched-execute from 1,762,241 → 1,919,712 (+157k). Root cause: on the realistic profile most effect slots are written 1-2× per batch, not 5+, so write coalescing doesn't recoup the read-side TLOAD tax. Same shape as the BC.slot0/1 rejection above — pattern: shadows of slots with high read-to-write ratios are net negative. Reverted in entirety; would only pay off on an effect-heavy profile (status-stacking, multi-effect mon-locals) that the realistic benchmark doesn't exercise. - **Diminishing returns going forward.** The remaining hot slots are effect mappings (`p0Effects[mon][eff].slot0/slot1` reads) — already amortized via warm-slot caching within the single `executeBuffered` tx. The next real lever would be a structural change: a per-batch cached `EffectInstance` array in transient (read all live effects once into memory, iterate from memory across sub-turns, flush deltas at end). That's a much bigger refactor than the field-level shadows above; queued for a future tier if a profile of an effect-heavy game shows it's worth it. ### Phase 1 (single-sig + compute-side trace) From 2b92c216a99917a992314e786ca7c4b36929c4c8 Mon Sep 17 00:00:00 2001 From: Claude Date: Sat, 23 May 2026 06:04:02 +0000 Subject: [PATCH 29/65] opt: coalesce _getActiveMonIndex reads within function frames (H) MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Each call to _getActiveMonIndex(battleKeyForWrite) compiles down to three TLOADs plus a stack frame the IR optimizer couldn't fold across distinct call points (~300-500g per call, not just one TLOAD as initially estimated).

Single-call sites (e.g., `dispatchStandardAttack`, `_handleMove` stamina deduct) were left alone since there's nothing to coalesce.

Implementation requires write-through to a memory cache from `addEffect` / `removeEffect` / `_updateOrRemoveEffect` to maintain coherency, plus a sparse memory layout to avoid 50KB+ memory-expansion costs on the cache structure. Complexity-to-savings ratio doesn't pencil — the cached reads are already warm SLOADs (100 gas), and the population/maintenance cost ate most of the win in back-of-envelope.

Complexity-to-savings ratio doesn't pencil — the cached reads are already warm SLOADs (100 gas), and the population/maintenance cost ate most of the win in back-of-envelope.

Also benchmarked a fully branchless variant (always SLOAD both slots, bit- select via sar/and/or) — measured ~15k worse than the branched version on the realistic 14-turn steady state, since the unconditional slot 1 warm SLOAD outweighs the JUMPI cost.

Modest in execute because the storage savings (~14 fewer warm SSTOREs, ~105 fewer warm SLOADs in batched execute — see access tally) are offset by the bytecode/branch overhead of the dispatch check on every effect read. - - **Setup-phase wins are larger** (where addEffect actually happens): `FirstBattle` -26,138 gas, `SecondBattle` -23,563 gas, `B1_Execute` -5,509 gas, `B1_Setup` -2,491 gas. These come from eliminating the slot 1 cold first-touch SSTORE per inline-fitting effect at registration time (~5-22k per add depending on cold/warm status). - - Access tally (batched execute steady state): SSTOREs 51 → 42 (-9, of which 9 are no-op eliminations), SLOADs 972 → 859 (-113). Cold SLOADs -8, warm SLOADs -105. - -- **Cumulative vs original baseline:** batched 1,762,241 → 1,587,360 = **-174,881 gas (-9.9%)**; legacy 1,867,567 → 1,710,105 = **-157,462 gas (-8.4%)**. Setup-heavy battles save another 20-26k each. - -- **StatBoosts behavior.** StatBoosts data is always 256 bits (168-bit identity key dominates), so its writes always hit the external slot 1 path. No regression: the runtime check costs ~10g per write, dwarfed by the 5k SSTORE itself. - diff --git a/snapshots/BetterCPUInlineGasTest.json b/snapshots/BetterCPUInlineGasTest.json index 6d246a0a..db323ef5 100644 --- a/snapshots/BetterCPUInlineGasTest.json +++ b/snapshots/BetterCPUInlineGasTest.json @@ -1,8 +1,8 @@ { - "Flag0_P0ForcedSwitch": "25611", - "Turn0_Lead": "126457", - "Turn1_BothAttack": "274966", - "Turn2_BothAttack": "249042", - "Turn3_BothAttack": "245066", - "Turn4_BothAttack": "245070" + "Flag0_P0ForcedSwitch": "25623", + "Turn0_Lead": "126505", + "Turn1_BothAttack": "274990", + "Turn2_BothAttack": "249066", + "Turn3_BothAttack": "245090", + "Turn4_BothAttack": "245094" } \ No newline at end of file diff --git a/snapshots/EngineGasTest.json b/snapshots/EngineGasTest.json index 0c67040a..d06a5488 100644 --- a/snapshots/EngineGasTest.json +++ b/snapshots/EngineGasTest.json @@ -1,21 +1,21 @@ { - "B1_Execute": "978897", - "B1_Setup": "848916", - "B2_Execute": "728861", - "B2_Setup": "308844", - "Battle1_Execute": "484058", + "B1_Execute": "984406", + "B1_Setup": "851407", + "B2_Execute": "730559", + "B2_Setup": "309146", + "Battle1_Execute": "484106", "Battle1_Setup": "826611", - "Battle2_Execute": "405267", + "Battle2_Execute": "405315", "Battle2_Setup": "245936", - "External_Execute": "494664", + "External_Execute": "494712", "External_Setup": "817345", - "FirstBattle": "3197157", - "Inline_Execute": "350660", + "FirstBattle": "3223295", + "Inline_Execute": "350708", "Inline_Setup": "227877", "Intermediary stuff": "45490", - "SecondBattle": "3261698", - "Setup 1": "1710632", - "Setup 2": "312508", - "Setup 3": "353838", - "ThirdBattle": "2592609" + "SecondBattle": "3285261", + "Setup 1": "1713123", + "Setup 2": "312999", + "Setup 3": "354329", + "ThirdBattle": "2595347" } \ No newline at end of file diff --git a/snapshots/EngineOptimizationTest.json b/snapshots/EngineOptimizationTest.json index a3782519..1f6fef8f 100644 --- a/snapshots/EngineOptimizationTest.json +++ b/snapshots/EngineOptimizationTest.json @@ -1,4 +1,4 @@ { - "ExternalStaminaRegen": "441078", - "InlineStaminaRegen": "1105393" + "ExternalStaminaRegen": "441518", + "InlineStaminaRegen": "1108755" } \ No newline at end of file diff --git a/snapshots/FullyOptimizedInlineGasTest.json b/snapshots/FullyOptimizedInlineGasTest.json index ce39a7d4..39bc55a1 100644 --- a/snapshots/FullyOptimizedInlineGasTest.json +++ b/snapshots/FullyOptimizedInlineGasTest.json @@ -1,7 +1,7 @@ { - "Fast_Battle1": "2057327", - "Fast_Battle2": "1969906", - "Fast_Battle3": "1501718", + "Fast_Battle1": "2080847", + "Fast_Battle2": "1990694", + "Fast_Battle3": "1501838", "Fast_Setup_1": "1346581", "Fast_Setup_2": "219602", "Fast_Setup_3": "216058" diff --git a/snapshots/InlineEngineGasTest.json b/snapshots/InlineEngineGasTest.json index c979dce1..f046cce9 100644 --- a/snapshots/InlineEngineGasTest.json +++ b/snapshots/InlineEngineGasTest.json @@ -1,16 +1,16 @@ { - "B1_Execute": "954036", - "B1_Setup": "780921", - "B2_Execute": "681551", - "B2_Setup": "287877", - "Battle1_Execute": "431341", + "B1_Execute": "959655", + "B1_Setup": "783412", + "B2_Execute": "683359", + "B2_Setup": "288179", + "Battle1_Execute": "431389", "Battle1_Setup": "758608", - "Battle2_Execute": "350600", + "Battle2_Execute": "350648", "Battle2_Setup": "227205", - "FirstBattle": "2820565", - "SecondBattle": "2840661", - "Setup 1": "1634753", - "Setup 2": "321688", - "Setup 3": "317894", - "ThirdBattle": "2216298" + "FirstBattle": "2846703", + "SecondBattle": "2864224", + "Setup 1": "1637244", + "Setup 2": "322179", + "Setup 3": "318385", + "ThirdBattle": "2219036" } \ No newline at end of file diff --git a/snapshots/StandardAttackPvPGasTest.json b/snapshots/StandardAttackPvPGasTest.json index 7dbd304c..b08c3a54 100644 --- a/snapshots/StandardAttackPvPGasTest.json +++ b/snapshots/StandardAttackPvPGasTest.json @@ -1,5 +1,5 @@ { - "Turn0_Lead": "88223", + "Turn0_Lead": "88271", "Turn1_BothAttack": "140050", "Turn2_BothAttack": "100270", "Turn3_BothAttack": "100300", diff --git a/src/Engine.sol b/src/Engine.sol index c14c6ef9..6541f510 100644 --- a/src/Engine.sol +++ b/src/Engine.sol @@ -240,9 +240,13 @@ contract Engine is IEngine, MappingAllocator { uint256 numEffects = effects.length; if (numEffects > 0) { for (uint256 i = 0; i < numEffects;) { - uint16 bm = - address(effects[i]) == address(0) ?

CPU manager now supports a buffered flow that mirrors the PvP batched API: - selectMoveWithStateHint(battleKey, aliceMove, aliceExtra, aliceSalt, CPUContext calldata projectedState) — Alice supplies the projected post-prior-turn state in calldata; the CPU consumes it (unverified) to pick its move. Per §7.1 the hint isn't verified — lying just produces suboptimal CPU play against Alice herself, so there's no incentive to cheat. CPU salt = keccak(timestamp, aliceSalt, turnId) per §7.4 (turnId guards against in-block collisions). Emits CPUTurnSalt(battleKey, turnId, timestamp) for off-chain replay. - executeBuffered(battleKey) — drains the buffer in one tx via engine.executeBatchedTurns. Anyone can call (auth lives at the engine gate via msg.sender == config.moveManager, and this contract IS the moveManager for battles started via it). Fires _afterTurn on game-end. Buffer layout matches SignedCommitManager exactly (same 256-bit packed slot, same counter packing) so engine.executeBatchedTurns consumes either buffer interchangeably. Legacy selectMove stays callable on the same contract; first-of-batch sync to engine's turnId makes mid-battle mode alternation seamless. Tests (test/CPUBatchTest.sol, 7 passing): single-submit-execute, multi-batch counter accounting, legacy↔batched mode alternation, empty-buffer revert, non-p0 revert, game-over revert (HP=20 1-hit-KO orchestration), and the lying-hint scenario (engine state stays consistent under deliberately-wrong CPUContext). Uses MockBatchedCPU (deterministic scripted moves) to avoid coupling tests to real CPU heuristics. Byte-equivalence vs legacy selectMove is NOT verified — legacy salt is keccak(battleKey, msg.sender, timestamp) vs batched's keccak(timestamp, aliceSalt, turnId), so engine RNG differs and damage rolls diverge. Behavioural equivalence (battle completes, state consistent, counters correct) is what the suite asserts. Caveat for production CPUs: OkayCPU/FairCPU/BetterCPU make engine state reads inside calculateMove. In batched mode those return STALE state (engine hasn't advanced past prior buffered turns), so CPU quality drops — exactly the trade-off documented in §7.1. Fix is to migrate each CPU to ctx-only logic; not blocking this ship. Adding storage (moveBuffer + bufferCounters) to CPUMoveManager shifts optimizer choices for all subclasses — BetterCPUInlineGasTest regressed ~387g per turn (~0.2% per scenario). Acceptable for the new feature. --- OPT_PLAN.md | 22 +- snapshots/BetterCPUInlineGasTest.json | 12 +- src/cpu/CPUMoveManager.sol | 202 ++++++++++++++++ test/CPUBatchTest.sol | 325 ++++++++++++++++++++++++++ test/mocks/MockBatchedCPU.sol | 75 ++++++ 5 files changed, 622 insertions(+), 14 deletions(-) create mode 100644 test/CPUBatchTest.sol create mode 100644 test/mocks/MockBatchedCPU.sol diff --git a/OPT_PLAN.md b/OPT_PLAN.md index 539776eb..8e184463 100644 --- a/OPT_PLAN.md +++ b/OPT_PLAN.md @@ -534,16 +534,22 @@ The actual decoupling: per-turn buffer + `executeBuffered` looping `_executeInte - [x] `test/BatchEdgeTest.sol`: forced-switch dispatch (`flag != 2`), single-side switch, mid-batch game-over (`ex` advances by actually-executed, not buffered), mode alternation (legacy↔batched seamless). - [x] `test/BatchGasTest.sol`: comparison harness for B ∈ {2, 4, 8}. **Current numbers show batched is more expensive than legacy** — recorded in §12 Decision Log. -### Phase 2.5 — CPU mode +### Phase 2.5 — CPU mode ✅ (API + correctness) -CPU manager rides the same buffer + `executeBatch`.

Battles can alternate between them turn-by-turn — first batched submission syncs `numExecuted` to engine's current `turnId` so the transition is seamless (verified by `test_batched_modeAlternation_legacyThenBatched`). + +**Caveat on real-CPU calculateMove in batched mode:** all 3 production CPU implementations (`OkayCPU`, `FairCPU`, `BetterCPU`) make multiple `ENGINE.X` calls inside `calculateMove` (e.g. `getMoveDecisionForBattleState`, `getMonStateForBattle`, `getDamageCalcContext`). In batched mode those reads return STALE state (engine hasn't advanced past prior buffered turns yet), so the CPU may make objectively-worse decisions. This is the spec'd trade-off — per §7.1, "Lying never benefits Alice — it makes the CPU's chosen move suboptimal against her." If future profiling shows the CPU quality drop matters for UX, the fix is to migrate each CPU to use only `ctx` + parameters (no engine calls); the CPUContext already carries enough info for most decisions. ### Phase 3 / 4 — deferred diff --git a/snapshots/BetterCPUInlineGasTest.json b/snapshots/BetterCPUInlineGasTest.json index db323ef5..0d1343c8 100644 --- a/snapshots/BetterCPUInlineGasTest.json +++ b/snapshots/BetterCPUInlineGasTest.json @@ -1,8 +1,8 @@ { - "Flag0_P0ForcedSwitch": "25623", - "Turn0_Lead": "126505", - "Turn1_BothAttack": "274990", - "Turn2_BothAttack": "249066", - "Turn3_BothAttack": "245090", - "Turn4_BothAttack": "245094" + "Flag0_P0ForcedSwitch": "25760", + "Turn0_Lead": "126891", + "Turn1_BothAttack": "275377", + "Turn2_BothAttack": "249453", + "Turn3_BothAttack": "245477", + "Turn4_BothAttack": "245481" } \ No newline at end of file diff --git a/src/cpu/CPUMoveManager.sol b/src/cpu/CPUMoveManager.sol index 52b0c109..443eab0c 100644 --- a/src/cpu/CPUMoveManager.sol +++ b/src/cpu/CPUMoveManager.sol @@ -10,7 +10,26 @@ import {ICPU} from "./ICPU.sol"; abstract contract CPUMoveManager { IEngine internal immutable ENGINE; + /// @notice Per-turn buffer slot: same layout as `SignedCommitManager.moveBuffer`.

Single-tx harness gas comparison at B ∈ {4, 8, 14, 20, 30} plus a per-turn access tally (test_cpuBatchAccessTally_B14) recording each call's storage diff separately so we get production-accurate cold/warm split. Empirical findings vs MockBatchedCPU (deterministic, no engine reads): B=4: legacy 537k, batched 656k (in-harness +119k worse, prod +110k) B=8: legacy 1.04M, batched 1.28M (in-harness +240k, prod +135k) B=14: legacy 1.80M, batched 2.22M (in-harness +423k, prod +174k) B=20: legacy 2.55M, batched 3.16M (in-harness +610k, prod +217k) B=30: legacy 3.81M, batched 4.74M (in-harness +929k, prod +296k) Per-turn harness regression is a CONSTANT ~30k (independent of B), so the cold-tx penalty savings (~270k for B=14, scaling slightly with N) never overtake it. CPU batched is a UX feature (async queueing) but not a gas optimization at any practical B. The access-tally test gives the authoritative cold-touch counts that ground the production estimate (vs the heuristic in BatchGasTest): Legacy: 280 cold first-touches across 14 selectMove txs (~20/tx) Batched submits: 112 cold across 14 submit txs (~8/tx) Batched executeBuffered: 33 cold (1 tx) Delta: 135 cold first-touches saved in batched = ~270k saved. --- test/CPUBatchGasTest.sol | 459 +++++++++++++++++++++++++++++++++++++++ 1 file changed, 459 insertions(+) create mode 100644 test/CPUBatchGasTest.sol diff --git a/test/CPUBatchGasTest.sol b/test/CPUBatchGasTest.sol new file mode 100644 index 00000000..fb1ec48c --- /dev/null +++ b/test/CPUBatchGasTest.sol @@ -0,0 +1,459 @@ +// SPDX-License-Identifier: AGPL-3.0 +pragma solidity ^0.8.0; + +import "../lib/forge-std/src/Test.sol"; + +import "../src/Constants.sol"; +import "../src/Enums.sol"; +import "../src/Structs.sol"; + +import {Engine} from "../src/Engine.sol"; +import {DefaultValidator} from "../src/DefaultValidator.sol"; +import {IEffect} from "../src/effects/IEffect.sol"; +import {IEngine} from "../src/IEngine.sol"; +import {IEngineHook} from "../src/IEngineHook.sol"; +import {IMoveSet} from "../src/moves/IMoveSet.sol"; +import {IRandomnessOracle} from "../src/rng/IRandomnessOracle.sol"; +import {IRuleset} from "../src/IRuleset.sol"; +import {IValidator} from "../src/IValidator.sol"; +import {StandardAttackFactory} from "../src/moves/StandardAttackFactory.sol"; +import {ATTACK_PARAMS} from "../src/moves/StandardAttackStructs.sol"; +import {DefaultRandomnessOracle} from "../src/rng/DefaultRandomnessOracle.sol"; + +import {MockBatchedCPU} from "./mocks/MockBatchedCPU.sol"; +import {CPUMoveManager} from "../src/cpu/CPUMoveManager.sol"; +import {TestTeamRegistry} from "./mocks/TestTeamRegistry.sol"; +import {TestTypeCalculator} from "./mocks/TestTypeCalculator.sol"; + +/// @notice CPU batched-mode gas comparison: drive an N-turn CPU battle through legacy +/// `cpu.selectMove × N` vs batched `cpu.selectMoveWithStateHint × N + executeBuffered × 1` +/// and print the gas delta.

RNG differs → engine RNG output differs → damage rolls differ.

Battles can alternate between them turn-by-turn — first batched submission syncs `numExecuted` to engine's current `turnId` so the transition is seamless (verified by `test_batched_modeAlternation_legacyThenBatched`). - -**Caveat on real-CPU calculateMove in batched mode:** all 3 production CPU implementations (`OkayCPU`, `FairCPU`, `BetterCPU`) make multiple `ENGINE.X` calls inside `calculateMove` (e.g. `getMoveDecisionForBattleState`, `getMonStateForBattle`, `getDamageCalcContext`). In batched mode those reads return STALE state (engine hasn't advanced past prior buffered turns yet), so the CPU may make objectively-worse decisions. This is the spec'd trade-off — per §7.1, "Lying never benefits Alice — it makes the CPU's chosen move suboptimal against her." If future profiling shows the CPU quality drop matters for UX, the fix is to migrate each CPU to use only `ctx` + parameters (no engine calls); the CPUContext already carries enough info for most decisions. +- [ ] `selectMoveWithStateHint(bytes32, uint8, uint16, uint104, CPUContext calldata)` on `CPUMoveManager.sol` (§7.4). +- [ ] CPU salt derivation + `CPUTurnSalt(battleKey, turnId, timestamp)` event. +- [ ] Pack `(aliceMove, computedCpuMove)` into `PackedTurnEntry` and SSTORE to `moveBuffer`. +- [ ] `test/CPUBatchEquivalenceTest.sol`: 24-turn legacy vs `selectMoveWithStateHint × 24 + executeBatch × 3` byte-equality. +- [ ] Lying-hint test confirms §7.1 trust model. +- [ ] `test/BetterCPUBatchGasTest.sol`: mirror inline tests; snapshot B=1/4/8. ### Phase 3 / 4 — deferred diff --git a/snapshots/BetterCPUInlineGasTest.json b/snapshots/BetterCPUInlineGasTest.json index 0d1343c8..db323ef5 100644 --- a/snapshots/BetterCPUInlineGasTest.json +++ b/snapshots/BetterCPUInlineGasTest.json @@ -1,8 +1,8 @@ { - "Flag0_P0ForcedSwitch": "25760", - "Turn0_Lead": "126891", - "Turn1_BothAttack": "275377", - "Turn2_BothAttack": "249453", - "Turn3_BothAttack": "245477", - "Turn4_BothAttack": "245481" + "Flag0_P0ForcedSwitch": "25623", + "Turn0_Lead": "126505", + "Turn1_BothAttack": "274990", + "Turn2_BothAttack": "249066", + "Turn3_BothAttack": "245090", + "Turn4_BothAttack": "245094" } \ No newline at end of file diff --git a/src/cpu/CPUMoveManager.sol b/src/cpu/CPUMoveManager.sol index 443eab0c..52b0c109 100644 --- a/src/cpu/CPUMoveManager.sol +++ b/src/cpu/CPUMoveManager.sol @@ -10,26 +10,7 @@ import {ICPU} from "./ICPU.sol"; abstract contract CPUMoveManager { IEngine internal immutable ENGINE; - /// @notice Per-turn buffer slot: same layout as `SignedCommitManager.moveBuffer`.

The "CPU" is a phantom opponent address; all decision logic lives off-chain (player runs the transpiled engine locally to pick the CPU's response, then submits both moves). Why this works: no counterparty to cheat. The player can submit any CPU move she wants — misrepresenting the CPU's "ideal" response just produces a worse experience for the player herself. Eliminates the entire on-chain ICPU.calculateMove path that legacy OkayCPU/FairCPU/BetterCPU pay for per turn. What was deleted vs the prior design: - CPUContext calldata hint param (~640 bytes calldata) - ICPU.calculateMove STATICCALL dispatch (~700g/submit + body) - keccak salt derivation (~80g) - per-submit CPUTurnSalt event (~2k) Per-submit cost: ~43k (prior hint design) → ~22k (this). Files: - src/cpu/BatchedCPUMoveManager.sol — abstract with submitTurn + executeBuffered + IMatchmaker. Reuses SignedCommitManager's buffer layout exactly so engine.executeBatchedTurns is shared. - test/mocks/SimpleBatchedCPU.sol — minimal concrete leaf (adds startBattle). - test/BatchedCPUTest.sol — 6 functional tests (submit-execute, multi-batch counter accounting, empty-buffer / non-p0 / post-game-over reverts, buffered-turn readback). - test/BatchedCPUGasTest.sol — gas + cold-access tally vs OkayCPU. Measured at B=14 (test/BatchedCPUGasTest.sol): in-harness: legacy 2,637,557 batched 2,030,352 -23.0% / -607k prod estimate: legacy ~3.49M batched ~2.53M ~-28% / -960k cold delta: 279 -> 92 (-187 cold first-touches in prod) Legacy CPU contracts (CPUMoveManager, CPU, OkayCPU, FairCPU, BetterCPU) and their tests are completely untouched — this is purely additive. Battles choose one model at startBattle time via the moveManager field; mid-battle alternation between the two CPU contracts isn't supported (legacy and batched are separate products). OPT_PLAN §7 rewritten to reflect the new design; §11 Phase 2.5 marked done with measured numbers.

Layout (256 bits, keyed by storageKey so it reuses across battles via the engine's MappingAllocator pattern): [0..30] numExecuted (uint31) [31] gameOverFlag (1 bit) [32..63] numBuffered (uint32) [64..95] lastSubmitTs (uint32, year 2106 overflow) [96..255] p0 (160-bit address) Plus a separate `storageKeyOf[battleKey]` cache lets us skip getStorageKey on subsequent submits (battleKey -> storageKey is immutable per battle). Hot path (cache hit, all submits after the first): 1 SLOAD storageKeyOf[battleKey] 1 SLOAD bufferState[storageKey] -> p0, gameOver, counters 1 SSTORE moveBuffer[storageKey][nextTurnId] 1 SSTORE bufferState[storageKey] (preserves p0, increments numBuffered) Cold path (first submit per battle): falls back to getSubmitContext to populate both caches, sync counters to engine's turnId, and continue. executeBuffered: - Sets gameOverFlag if winner != 0 so subsequent submits revert fast. - Cold engine.end() timeouts won't propagate here (battle ends without touching this manager's state) but the manager isn't load-bearing for that flow anyway — it just won't accept new submits, which is the correct behavior. Measured at B=14 (test/BatchedCPUGasTest.sol): Submits: 301,998 -> 284,442 (-17,556 / -5.8%) Execute: 1,695,762 -> 1,694,541 (-1,221) Total: 1,997,760 -> 1,978,983 (-18,777 / -0.9%) Cold first-touches: 92 -> 79 (-13 -> ~-26k production cold penalty) In-harness saves vs legacy at B=14 went from 607,205 to 629,244 (+22k).

Battles with `moveManager` set continue to go through the manager unchanged. The engine has its own EIP-712 domain ("Engine","1") so sigs signed for the manager DON'T verify against the engine's direct path — prevents cross-contamination if someone tries to relay a manager-bound sig. Caveat (documented in the function): stall-timeout via Engine.end() requires either a `validator` set on the battle or hitting MAX_BATTLE_DURATION. The inline timeout path calls into a commit manager (which doesn't exist here). Battles using the direct path should set a validator if they need stall-timeout semantics. Measured at B=14 (test/EngineDualSignedDirectTest.sol): via manager: 1,741,827 gas via engine direct: 1,696,946 gas saved: 44,881 gas (~3.2k per turn / ~2.6%) Snapshot regression: ~300g per scenario across EngineGasTest / StandardAttackPvPGasTest / etc. — bytecode bloat from EIP712 base + new function.

Cache miss implies first submit of this battle, so we unconditionally reset `packed` to (ctxTurnId, ctxP0). Any prior battle's leftover state at this storageKey (gameOver flag, old numExecuted from MappingAllocator reuse) is overwritten — the new battle owns the slot. Saves ~2k cold SLOAD per first-submit per battle in production. 2. executeBuffered _afterBattle: use cached p0 from `packed` instead of an extra STATICCALL into `engine.getPlayersForBattle`. Saves ~3k per game-end transition. In the test harness, the warmup populates the bufferState slot before the measured battle starts (MappingAllocator reuses storageKey), so the cache-miss SLOAD is already warm in the test. The savings only show up in production where each submit is its own tx. All 549 tests pass.

Storage-side scan against live + tombstoned slots; only calls _addEffectInternal when not already present. - getAndInitGlobalKV(key, valueIfZero) -> previousValue Read + conditional init in one call. Useful for once-per-battle flag patterns (~5 sites). Eagerly initializes if previous was zero, so callers that need conditional set-after-work should keep the split form. - getMoveContext(battleKey, atkPlayer, atkMon, defPlayer, defMon) Returns MonStats + MonState + EffectInstance[] for both sides in one view. Replaces the 4-7 individual getMonStatsForBattle / getMonStateForBattle / getEffects callbacks the worst-offender custom moves do today. Sentinel deltas are sanitized to 0 to match getMonStateForBattle semantics; tombstoned slots are filtered out. No existing call sites are migrated; all 557 existing tests pass. Snapshots show a small (~+1000g per execute) dispatch-table regression from the three new selectors, which migration of custom moves to these APIs will recoup several times over. Eight new tests in EngineMoveAPITest cover correctness and write-context gating for all three APIs. --- snapshots/BetterCPUInlineGasTest.json | 12 +- snapshots/EngineGasTest.json | 36 ++-- snapshots/EngineOptimizationTest.json | 4 +- snapshots/FullyOptimizedInlineGasTest.json | 12 +- snapshots/InlineEngineGasTest.json | 28 +-- snapshots/MatchmakerTest.json | 6 +- snapshots/StandardAttackPvPGasTest.json | 10 +- src/Engine.sol | 103 ++++++++++ src/IEngine.sol | 25 +++ src/Structs.sol | 15 ++ test/EngineMoveAPITest.sol | 212 +++++++++++++++++++++ test/mocks/MockNewAPIMove.sol | 90 +++++++++ 12 files changed, 499 insertions(+), 54 deletions(-) create mode 100644 test/EngineMoveAPITest.sol create mode 100644 test/mocks/MockNewAPIMove.sol diff --git a/snapshots/BetterCPUInlineGasTest.json b/snapshots/BetterCPUInlineGasTest.json index 84f37fdd..0d822cd3 100644 --- a/snapshots/BetterCPUInlineGasTest.json +++ b/snapshots/BetterCPUInlineGasTest.json @@ -1,8 +1,8 @@ { -

Pure dead dispatch-table weight. Verified by direct grep across src/, test/, script/: only the IEngine declarations and Engine implementations themselves reference these names. Saves ~250-650g per external call to the engine on every code path, ~3-4k per battle setup. Partial offset against the +1000g/execute regression from the three new coalesced move-facing APIs in 6276d2c. Also corrects the CommitContext doc comment — the lightweight context's real benefit over BattleContext is fewer encoded return fields (cheaper ABI encode/decode), not fewer SLOADs (both getters load the same storage slots). Confirmed by measuring a CommitContext → BattleContext swap that regressed execute paths by +5k each. All 557 tests pass. --- snapshots/BetterCPUInlineGasTest.json | 12 ++++++------ snapshots/EngineGasTest.json | 18 +++++++++--------- snapshots/EngineOptimizationTest.json | 4 ++-- snapshots/FullyOptimizedInlineGasTest.json | 6 +++--- snapshots/InlineEngineGasTest.json | 14 +++++++------- snapshots/StandardAttackPvPGasTest.json | 10 +++++----- src/Engine.sol | 8 -------- src/IEngine.sol | 2 -- src/Structs.sol | 2 +- 9 files changed, 33 insertions(+), 43 deletions(-) diff --git a/snapshots/BetterCPUInlineGasTest.json b/snapshots/BetterCPUInlineGasTest.json index 0d822cd3..9b6dfb1e 100644 --- a/snapshots/BetterCPUInlineGasTest.json +++ b/snapshots/BetterCPUInlineGasTest.json @@ -1,8 +1,8 @@ { - "Flag0_P0ForcedSwitch": "25241", - "Turn0_Lead": "125600", - "Turn1_BothAttack": "275191", - "Turn2_BothAttack": "249267", - "Turn3_BothAttack": "245291", - "Turn4_BothAttack": "245295" + "Flag0_P0ForcedSwitch": "25197", + "Turn0_Lead": "125556", + "Turn1_BothAttack": "275147", + "Turn2_BothAttack": "249223", + "Turn3_BothAttack": "245247", + "Turn4_BothAttack": "245251" } \ No newline at end of file diff --git a/snapshots/EngineGasTest.json b/snapshots/EngineGasTest.json index 7bb3ebaa..6b63f7c8 100644 --- a/snapshots/EngineGasTest.json +++ b/snapshots/EngineGasTest.json @@ -1,21 +1,21 @@ { - "B1_Execute": "985217", + "B1_Execute": "984557", "B1_Setup": "851627", - "B2_Execute": "731380", + "B2_Execute": "730720", "B2_Setup": "309356", - "Battle1_Execute": "483607", + "Battle1_Execute": "483343", "Battle1_Setup": "826831", - "Battle2_Execute": "404816", + "Battle2_Execute": "404552", "Battle2_Setup": "246156", - "External_Execute": "492185", + "External_Execute": "491921", "External_Setup": "817565", - "FirstBattle": "3227041", - "Inline_Execute": "347235", + "FirstBattle": "3223785", + "Inline_Execute": "347147", "Inline_Setup": "228097", "Intermediary stuff": "45490", - "SecondBattle": "3290704", + "SecondBattle": "3286876", "Setup 1": "1713343", "Setup 2": "313219", "Setup 3": "354549", - "ThirdBattle": "2599093" + "ThirdBattle": "2595837" } \ No newline at end of file diff --git a/snapshots/EngineOptimizationTest.json b/snapshots/EngineOptimizationTest.json index 76e401d6..8c1259ec 100644 --- a/snapshots/EngineOptimizationTest.json +++ b/snapshots/EngineOptimizationTest.json @@ -1,4 +1,4 @@ { - "ExternalStaminaRegen": "442460", - "InlineStaminaRegen": "1108127" + "ExternalStaminaRegen": "442108", + "InlineStaminaRegen": "1107731" } \ No newline at end of file diff --git a/snapshots/FullyOptimizedInlineGasTest.json b/snapshots/FullyOptimizedInlineGasTest.json index 78077278..3f80ccfd 100644 --- a/snapshots/FullyOptimizedInlineGasTest.json +++ b/snapshots/FullyOptimizedInlineGasTest.json @@ -1,7 +1,7 @@ { - "Fast_Battle1": "2063824", - "Fast_Battle2": "1973059", - "Fast_Battle3": "1484815", + "Fast_Battle1": "2062196", + "Fast_Battle2": "1970991", + "Fast_Battle3": "1483187", "Fast_Setup_1": "1346977", "Fast_Setup_2": "219998", "Fast_Setup_3": "216454" diff --git a/snapshots/InlineEngineGasTest.json b/snapshots/InlineEngineGasTest.json index 304dc840..46ff695f 100644 --- a/snapshots/InlineEngineGasTest.json +++ b/snapshots/InlineEngineGasTest.json @@ -1,16 +1,16 @@ { - "B1_Execute": "955642", + "B1_Execute": "955246", "B1_Setup": "783632", - "B2_Execute": "679356", + "B2_Execute": "678960", "B2_Setup": "288389", - "Battle1_Execute": "427916", + "Battle1_Execute": "427828", "Battle1_Setup": "758828", - "Battle2_Execute": "347175", + "Battle2_Execute": "347087", "Battle2_Setup": "227425", - "FirstBattle": "2844063", - "SecondBattle": "2862437", + "FirstBattle": "2841863", + "SecondBattle": "2859753", "Setup 1": "1637464", "Setup 2": "322399", "Setup 3": "318605", - "ThirdBattle": "2216396" + "ThirdBattle": "2214196" } \ No newline at end of file diff --git a/snapshots/StandardAttackPvPGasTest.json b/snapshots/StandardAttackPvPGasTest.json index da849ab3..02975386 100644 --- a/snapshots/StandardAttackPvPGasTest.json +++ b/snapshots/StandardAttackPvPGasTest.json @@ -1,7 +1,7 @@ { - "Turn0_Lead": "86479", - "Turn1_BothAttack": "138465", - "Turn2_BothAttack": "98685", - "Turn3_BothAttack": "98715", - "Turn4_BothAttack": "98743" + "Turn0_Lead": "86435", + "Turn1_BothAttack": "138421", + "Turn2_BothAttack": "98641", + "Turn3_BothAttack": "98671", + "Turn4_BothAttack": "98699" } \ No newline at end of file diff --git a/src/Engine.sol b/src/Engine.sol index 0929fcce..d3dbde08 100644 --- a/src/Engine.sol +++ b/src/Engine.sol @@ -3225,10 +3225,6 @@ contract Engine is IEngine, MappingAllocator, EIP712 { p1Levels = TeamLevelInfo({monIds: p1MonIds, exp: p1Exp, levels: p1LevelArr});

Each migration drops ~7 lines of boilerplate + one STATICCALL for getEffects + the in-move loop iteration. Sites migrated (all 12 are clean dedup-on-address pattern): aurox: IronWall, UpOnly ekineki: SneakAttack (special: guards entire body, uses returned bool) embursa: Tinderclaws (activateOnSwitch only; _removeBurnIfPresent kept) gorillax: Angery inutia: ChainExpansion, Interweaving malalien: ActusReus nirvamma: Adaptor pengym: PostWorkout sofabbi: CarrotHarvest xmon: Dreamcatcher, Somniphobia IronWall and SneakAttack use the `if (!addEffectIfNotPresent(...)) return;` form because the effect-presence check guards the entire function body (initial heal / damage calc skipped on subsequent calls in the same lifecycle). NOT migrated (different semantics): ghouliath/RiseFromTheGrave — uses globalKV flag, not getEffects nirvamma/HardReset — data-bit conditional dedup xmon/NightTerrors — find-or-update, not add-only embursa/Tinderclaws site 2 (_removeBurnIfPresent) — remove pattern aurox/GildedRecovery — remove pattern iblivion/Baselight — _findEffect tuple-returning helper All 557 tests pass. --- src/mons/aurox/IronWall.sol | 14 ++++---------- src/mons/aurox/UpOnly.sol | 13 +++---------- src/mons/ekineki/SneakAttack.sol | 13 ++++--------- src/mons/embursa/Tinderclaws.sol | 11 ++--------- src/mons/gorillax/Angery.sol | 12 ++---------- src/mons/inutia/ChainExpansion.sol | 12 ++---------- src/mons/inutia/Interweaving.sol | 14 +++----------- src/mons/malalien/ActusReus.sol | 13 +++---------- src/mons/nirvamma/Adaptor.sol | 12 ++---------- src/mons/pengym/PostWorkout.sol | 11 ++--------- src/mons/sofabbi/CarrotHarvest.sol | 12 ++---------- src/mons/xmon/Dreamcatcher.sol | 13 +++---------- src/mons/xmon/Somniphobia.sol | 13 +++---------- 13 files changed, 35 insertions(+), 128 deletions(-) diff --git a/src/mons/aurox/IronWall.sol b/src/mons/aurox/IronWall.sol index 8f540ecc..66a949b4 100644 --- a/src/mons/aurox/IronWall.sol +++ b/src/mons/aurox/IronWall.sol @@ -4,7 +4,7 @@ pragma solidity ^0.8.0;

Keeping a one-consumer API plus paying its dispatch cost on every other engine call doesn't pencil out. Reverts SneakAttack to its original individual-getter form (keeping the addEffectIfNotPresent change from d1edf81). Drops getMoveContext + the _sanitizeMonState helper from Engine.sol, the IEngine declaration, the MoveContext struct from Structs.sol, and the three EngineMoveAPITest cases.

Versus the original baseline (commit bdc0505, pre-APIs), all hot paths are now NEGATIVE gas — the engine is leaner than before this exercise started.

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.

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.

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.

There is no partial-batch mode in v1. -- Processed buffer slots are not cleared — the unbounded mapping leaves them for on-chain replay.

Legacy `DefaultCommitManager.commitMove`/`revealMove` writes `config.p0Move` etc. and triggers `execute()` immediately; the batched path never reads that storage.

Switch turns reuse the same shape (non-acting player signs + `NO_OP`). +- **Off-chain CPU batched mode** (`BatchedCPUMoveManager`). Player computes the CPU's move + off-chain via the transpiled engine and submits `(playerMove, cpuMove)` tuples to an + on-chain buffer. Trust model: no counterparty to cheat — bad CPU moves just hurt the + player. Eliminates per-submit `ICPU.calculateMove` STATICCALL, salt derivation, and the + per-turn event. +- **Engine-direct dual-signed entry** (`Engine.executeWithDualSignedMovesDirect`). Opt-in + via `moveManager == address(0)`. Inlines EIP-712 reveal-sig verification + auth, + skipping the manager STATICCALL. + +### Transient shadow layer (batched path only) +- BD slot 1 (turnId, winner, switchFlag, activeMonIndex, lastExecuteTimestamp) — single + SSTORE per batch instead of per turn. +- MonState for both sides' active mons. Flush skipped on game-end (next `startBattle` + resets the slot anyway). +- `koBitmaps` narrowed shadow — just the 16-bit field, not all of BC slot 2, so reads of + immutable BC slot 2 fields stay direct. + +### Storage layout repacks +- `BattleData` split into slot 0 (immutable during play: p1, team indices) + slot 1 + (every per-turn mutation packed into 256 bits). `turnId` uint64→uint16, + `lastExecuteTimestamp` uint48→uint40. +- `BattleConfig` slot 2 fully packed (256 bits exact, `koBitmaps` for both players folded + into one 16-bit field). +- `MoveDecision` reduced to one 24-bit packed slot (`packedMoveIndex` 8b + extraData 16b). + +### Single-tx engine wins (apply to both flows) +- Per-turn move/salt transients merged from 4 slots to 1 (saves 3 TSTOREs/call). +- Per-turn event emission dropped from `_executeInternal` (~1.5k/turn). +- Constant `BattleConfig` fields hoisted out of the per-turn loop. +- `BD-slot-1` reads coalesced into a single stack-cached `packed` value, decoded per field + on demand. +- `_handleEffectsTriple` fused dispatch for RoundStart + RoundEnd lifecycle steps. +- `battleKeyForWrite` cached per frame; `_getActiveMonIndex` reads coalesced within + function frames. +- Single-sig dual-signed flows (committer identified by `msg.sender`, not a separate + signature). + +### Move-facing API additions +- `addEffectIfNotPresent` — coalesces the canonical "iterate `getEffects` to dedup, then + `addEffect`" pattern. **12 mons migrated** in `src/mons/`. +- `getSubmitContext` — minimal context for async submission (1 call + 3 SLOADs vs + `getCommitContext` + `getStorageKey`'s 2 calls + 5 SLOADs). +- `getStorageKey` — managers key their own buffers by storageKey to share + `MappingAllocator`'s slot reuse. + +### Engine surface trims (net dispatch reduction) +- Removed: `getMoveManager`, `getBattleValidator`, `getMonStateForStorageKey`, + `getPrevPlayerSwitchForTurnFlagForBattleState` (zero callers in `src/`, test-only or + fully dead). --- -## 5.

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`.

CPU mode (off-chain decisions, batched submit) - -Same per-turn buffer + `executeBatchedTurns` as PvP. The "CPU" is a phantom opponent address; -all decision logic lives off-chain. The player runs the transpiled engine locally to pick the -CPU's response, then submits both moves on-chain. No on-chain `calculateMove`, no `CPUContext` -calldata hint, no per-submit event. The per-submit cost drops to roughly `getSubmitContext + -2 × SSTORE`. - -### 7.1 Trust model +## Measured savings -There's no counterparty to cheat. The player can submit any CPU move she wants — misrepresenting -the CPU's "ideal" response just produces a worse experience for the player herself. Since the -CPU has no stake, no balance, no opinion, there's nothing to defend against. This eliminates -the entire on-chain CPU compute path that legacy `CPUMoveManager.selectMove` pays for per turn. - -### 7.2 No signature - -Player calls directly from her wallet. Manager checks `msg.sender == p0`. The tx is the proof -— no relay path needed for a single-human flow. - -### 7.3 Off-chain protocol - -Each turn, locally on the player's client: -1. Hold current engine state (post-prior-turn snapshot from local sim). -2. Pick the player's move. -3. Run her chosen CPU strategy off-chain to pick the CPU's response. -4. Submit both moves on-chain via `submitTurn`. -5.

Migration - -Add new entry points alongside existing ones. No "batch mode" flag on a battle — `executeBatch` works on any battle that has buffered turns. - -Touched contracts: -- `Engine.sol`: `executeBatch` + shadow-transient layer + helper routing + flag-based per-turn dispatch. -- `IEngine.sol`: new function signatures. -- `SignedCommitManager.sol`: `submitTurnMoves` (sharing existing EIP-712 domain). -- `CPUMoveManager.sol`: `selectMoveWithStateHint`. -- `IMoveSet.sol`: narrow `extraData` to `uint16`. ~40 mon files take mechanical edits. - -Validator/legality is unchanged: signature recovery proves player intent (or `msg.sender == alice` for CPU); state-dependent illegality silently no-ops in `_handleMove`. 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.

Each entry: short context + the call made + why. - -### Cross-cutting - -- **Shadow layer deferred to follow-up.** §1-§5 of OPT_PLAN are organized around a transient shadow that mirrors `MonState` / `globalKV` / effect-slot reads inside `executeBatch`, then flushes once at the end. The motivating amortization (cold SLOADs are paid once per batch instead of once per turn) is *already* delivered for free by EVM warm-slot semantics: when `executeBatch` loops `_executeInternal` in one tx, the second iteration sees the slots from the first iteration as warm (100 gas) instead of cold (2100). The shadow's additional win is SSTORE deduplication across sub-turns (~5k per dedup'd write × multi-write count per turn). For v1 the warm-slot baseline plus single-tx amortization is enough to ship the gas-savings claim; the SSTORE-dedup follow-up is queued for v2. This deferral means Phases 0.5 and 1 stay in §11 unchecked, and Phase 2's `executeBatch` is built as a simple sub-turn loop over `_executeInternal`. - -### Phase 2 - -- **`executeBuffered` lives on the manager, not the engine.** §4.2 had `Engine.executeBatch(bytes32)` as a new engine entry point. Putting it on the manager instead keeps the engine ignorant of any specific commit-manager and avoids a new engine ↔ manager callback dance (engine asking the manager for buffer entries). The manager already has `IEngine`, so the loop is straightforward: read buffer slot → read live `playerSwitchForTurnFlag` → call `executeWithMoves` or `executeWithSingleMove`. No new engine surface needed except an extension to `resetCallContext`. Trade-off: the engine can never read from the buffer directly (e.g. for a single batch-aware `_executeInternal`-style optimization in the future). For v1 this is the right call. -- **Buffer keyed by `battleKey`, not `storageKey`.** §3 keyed `moveBuffer` by `storageKey` for slot reuse parity with `BattleConfig`. The manager doesn't actually care about slot reuse (entries are tiny — one `uint256` per turn), and `battleKey` is already unique per game via `pairHashNonce` increment. Using `battleKey` directly avoids needing a public `getStorageKey(bytes32)` accessor on the engine and keeps the manager fully decoupled from `MappingAllocator`. -- **Single `uint256` packed slot, no struct in storage.** §3 specified a `PackedTurnEntry` struct. Storing the packed `uint256` directly is one fewer SLOAD (no Solidity-generated wrapper), and the §3 bit layout is preserved exactly: `[p0Move 8 | p0Extra 16 | p0Salt 104 | p1Move 8 | p1Extra 16 | p1Salt 104]`. Internal `_packBufferedTurn` / `_unpackBufferedTurn` helpers handle the bit ops. -- **Extended `resetCallContext` instead of adding `resetPerTurnTransients`.** First pass added a parallel `resetPerTurnTransients()` external on the engine. The existing `resetCallContext()` already clears half of what was needed (per-turn move/salt encoded slots + `battleKeyForWrite` / `storageKeyForWrite`); extending it to also zero `tempRNG` / `koOccurredFlag` / `tempPreDamage` / `effectsDirtyBitmap` covers the rest and avoids two near-identical functions on `IEngine`. In legacy single-turn flow nothing changes — `resetCallContext` is only called by foundry test harnesses, where the extra zero TSTOREs are negligible. In batched flow `executeBuffered` calls `resetCallContext()` between sub-turns so each sub-turn starts with the same transient state the legacy per-tx flow would see. The four added clears are documented inline at `Engine.sol`'s `resetCallContext` body. -- **Game-over short-circuit test design.** First pass used a 2-mon game with HP=1 + power=100 on both sides, expecting "both mons die in turn 1." Trace showed the slower player's move short-circuits (`prevPlayerSwitchForTurnFlag != 2` after the faster player's KO chains into `_checkForGameOverOrKO`), so only ONE mon dies per damage trade. With 2-mon teams this means the battle needs ≥4 turns to wipe one side, and symmetric setups don't deterministically reach game-over within the buffered range. Rewrote with asymmetric setups (p0 fast/strong, p1 slow/glass) so p0 always KOs first and never gets KO'd — game ends deterministically on turn 3, the loop break is provably exercised. -- **Gas finding (critical):** the v1 batched flow (no shadow layer) is **measurably more expensive** than legacy dual-signed-per-turn execution. `test/BatchGasTest.sol` shows: - - | B | legacy | batched | delta | - |---|---|---|---| - | 2 | 211,458 | 282,674 | +71k (+33%) | - | 4 | 370,145 | 500,417 | +130k (+35%) | - | 8 | 687,748 | 936,847 | +249k (+36%) | - - Per-turn overhead breakdown: each `submitTurnMoves` costs ~22k cold-→-warm SSTORE for the buffer slot + ~5k warm-→-warm SSTORE for the counter slot + ~2k event + ~6k for the two sig recoveries (same as legacy). That's ~30k/turn more than legacy. The `executeBuffered` amortization across sub-turns only saves ~2k/turn per cold→warm engine SLOAD via EVM warm-storage discount (~16 cold SLOADs on a clean trade × 2k ≈ 32k saved per turn-after-the-first), which doesn't recoup the per-submission overhead until B is very large. - - The OPT_PLAN's gas claim (§1) was predicated on the §5 transient shadow layer doing SSTORE deduplication across sub-turns (the second sub-turn's `BattleData.turnId` etc. SSTOREs collapse to one final flush). Without the shadow, the engine SSTOREs every turn unchanged. **Phase 1 (shadow) is required to deliver the gas-savings claim.** Phase 2 as shipped delivers the decoupling API + correctness gate, plus the substrate Phase 1 will sit on top of. - -### Phase 0.1 - -- **Effect-heavy mock.** §0.1 mentioned "StatBoosts-style multi-stat effect + BurnStatus". Both have heavy external dependencies (StatBoosts needs its own deploy and per-mon snapshot KV; BurnStatus needs the StatBoosts instance). For an instrumentation test where only the per-turn storage-access pattern matters, that's overkill. Wrote a 50-LOC `test/mocks/PerTurnTickEffect.sol` that hooks RoundStart + RoundEnd + AfterDamage + ALWAYS_APPLIES and bumps a counter in `data` each tick. Same SLOAD/SSTORE shape (effect slot reads, data SSTOREs, count SLOADs in `_runEffects`), zero external setup. If the shadow layer ever needs differential testing against StatBoosts/Burn specifically, that belongs in Phase 1's effect-shadow correctness suite, not here. -- **Multi-mon scenario interpretation.** §0.1 wording was "all four mons referenced via onUpdateMonState listeners on bench mons". Production engine doesn't actually touch bench mons during a regular turn — only the active mons on each side. The natural multi-slot turn is a switch turn where p0 switches mon 0→1 while p1 attacks (touches p0 mon 0, p0 mon 1, p1 mon 0 = three distinct mon-state slots). Implemented that interpretation; logs show 16 cold SLOADs / 16 unique slots — slightly fewer than a clean trade because no second-attack SSTORE pattern. -- **Forced-switch entry point.** `_fastTurn` goes through `executeWithDualSignedMoves`, which reverts `NotTwoPlayerTurn()` once `playerSwitchForTurnFlag != 2`. Added a `_fastSinglePlayerTurn` helper that routes through `executeSinglePlayerMove(...)` with `vm.prank(actingPlayer)`. This is the same dispatch the production code does and matches what the batch flow will do via §6.1. - -### Phase 1 (MonState shadow) - -- **MonState shadow added on top of slot-1 shadow.** Mirrored the BattleData slot-1 shadow design at the MonState level: per-(player, monIndex) packed value cached in transient, dirty-bit tracked in `_shadowMonStateDirty`, flushed once at end of `executeBatchedTurns` via `_flushShadowMonStates(storageKey)`. Read/write helpers `_loadMonState` / `_storeMonState` use the packed transient when shadow is active and fall back to SLOAD/SSTORE otherwise — same dispatch as `_readBattleSlot1Packed`. Refactored all in-engine MonState mutation sites (`_dealDamageInternal`, `_updateMonStateInternal`, `_handleMove`'s stamina deduct, `_inlineRegenStaminaForMon`) and read-only sites that need to observe in-flight shadow values (`_computePriorityPlayerIndex`, `_getDamageCalcContextInternal`, `_readMonStateDelta`, `getCPUContext`, `getMonStatesForSide`, etc.) to use the memory-pattern via the helpers. -- **Realistic-game access tally (steady state, 14 turns): batched - legacy = -25 SSTOREs / -915 SLOADs**, a step up from the pre-MonState-shadow baseline of -5 SSTOREs / -793 SLOADs. The MonState shadow specifically coalesces 18 additional `nz->nz` SSTOREs (stamina/hpDelta mutations across sub-turns dedup'd by the per-mon transient) and 122 additional warm SLOADs (reads now hit the transient mirror inside the batch). -- **Legacy-path overhead trade-off.** The memory pattern (`_loadMonState` returns a `MonState memory`, all 9 fields unpacked; `_storeMonState` takes a `MonState memory`, all 9 fields repacked) replaces what used to be storage-ref-with-direct-field-access in the single-turn path. Snapshot diffs show legacy gas tests regressed ~5-8% per scenario (e.g. `Inline_Execute` +20k = +5.6%, `Battle1_Execute` +31k = +6.4%, `ThirdBattle` +224k = +8.6%). The unpack/repack costs ~270 gas/call (mostly memory expansion + shift ops); a 14-turn legacy game does ~140 such calls = ~38k. Live-with-it cost; the batched flow gains ~70k per game from the dedup, so net for users running the batched path is positive. If the legacy regression proves unacceptable downstream, the mitigation is per-field `_readMonStateField` / `_writeMonStateField` helpers that bypass the full unpack/repack in non-shadow mode — kept as a follow-up. -- **Steady-state harness for `BatchGasTest`.** The microbench previously measured battle 1 with HP=100000 (no KOs ever), conflating "cold storage" with "first-touch" and not exercising the engine's `MappingAllocator` free-list. Added a `_runWarmupAndCapture(useBatchedFlow)` helper that drives a low-HP (HP=20) battle to completion via the same flow the measured battle will use (so manager buffer slots warm for batched, only engine slots warm for legacy), then asserts `engine.getStorageKey(warm) == engine.getStorageKey(measured)` before measurement. This matches the harness in `BatchAccessProfileRealisticTest`. Gas numbers from this microbench are still inflated for legacy because all calls share warm-storage within one foundry tx (production legacy = N separate txs, each fresh); the access-tally in the realistic test is the authoritative measure of cold/warm separation. - -### Phase 1 (post-MonState follow-ups) - -- **Slot-bucket diagnostic in `BatchAccessProfileRealisticTest.test_realisticGameSlotBuckets`.** After BD.slot1 + MonState shadows the batched execute still touched 82 unique slots / 61 SSTOREs / 1021 SLOADs. Added a hash-anchored bucket helper that labels each accessed storage slot by its Engine region (BD.slotN, BC.slotN, MonState per-mon, Effects p0/p1/global, GlobalKV, etc.) so the remaining hot slots are visible at a glance. Top-write region was `BC.slot2` (KO bitmap + moveManager + teamSizes + startTs etc.) at 10 SSTOREs/game from KO-bit accumulation. -- **Step A: skip MonState flush on game-over.** When `executeBatchedTurns` exits with `winner != 0`, the next `startBattle` at this storageKey runs the sentinel-clear loop that overwrites every prior MonState slot anyway, so the un-flushed transient values are recycled either way. Wrapped `_flushShadowMonStates` in an `if (winner == address(0))` and explicitly clears `_shadowMonStateLoaded` / `_shadowMonStateDirty` in the skip path (otherwise a subsequent `executeBatchedTurns` in the same tx — multicall, or any foundry test — reads stale TLOAD bits from this batch and the game state diverges). BD.slot1 flushes unconditionally so `getWinner` stays correct. Saves 6 SSTOREs/game (the 4 + 2 dirty MonState slots at game-end). Trade-off: `getMonStateForBattle` returns stale values in the gap between batch-end and the next `startBattle`; user accepted (off-chain consumers replay from the move buffer). -- **Step B: narrow koBitmaps shadow.** `BC.slot2` packs 8 fields but only `koBitmaps` (uint16) mutates frequently mid-batch (one write per KO). Shadow just that 16-bit field — not the whole slot — into a dedicated transient (`_shadowKoBitmaps` + `_shadowKoBitmapsLoaded` + `_shadowKoBitmapsDirty`) so reads of immutable BC.slot2 fields (`moveManager`, `teamSizes`, `startTimestamp`, ...) stay as direct SLOADs and don't pay a TLOAD-check in legacy mode. Other field writes during the batch (e.g., `globalKVCount` bump) keep doing direct SSTORE; the unconditional flush at end-of-batch overwrites only the koBitmaps bits in storage so the shadowed value wins. Saves another 4 SSTOREs + 21 SLOADs per game (~12k gas). Legacy snapshot regression ~500 gas per game (0.1%) — small because the helper TLOAD-check is only on the koBit hot path, not on every BC.slot2 field read. -- **Final realistic-game steady-state delta: batched - legacy = -35 SSTOREs / -936 SLOADs** (from -25 / -915 after MonState shadow). Approximately 100k gas saved on SSTOREs + 94k saved on SLOADs = ~200k batched advantage per 14-turn game vs the legacy baseline. Per-slot proof of shadow batching: BD.slot1 14 writes → 1 (single flush), BC.slot2 koBitmaps ~5 writes → 0 (folded into one already-needed slot write), MonStates ~6 writes → 0 (game-over flush skip). - -> **HARNESS BIAS — important for reading the gas-measurement counterpart `test_realisticGameSteadyStateGas`.** `gasleft()` inside a single foundry test function measures all 14 legacy turns under ONE EVM transaction. Per EIP-2929 slots accessed in turn 1 become warm for turns 2-14 (SLOAD 100 instead of 2,100; SSTORE doesn't pay the cold-access penalty). In production each legacy turn is its own tx with cold-start access. Within-tx-warm measurement gives legacy ~1.99M / batched ~2.12M (batched looks +6.5% worse). Production estimate (adding ~260 cold-SLOAD penalties + 14× intrinsic tx cost): legacy ~2.81M / batched ~2.12M (batched saves ~390k, ~14%). The access-tally test is the authoritative steady-state production measure — it records each turn's state diff under its own per-call recording, so cold/warm classification is production-accurate. **Trust the SSTORE/SLOAD count delta, not the single-tx gasleft() number.** -- **Stopped here.** Three further candidates were measured and rejected: - - **Effect-data no-op write guard.** Initial diagnostic flagged 21 effect-data no-op SSTOREs per game; I sized this at ~46k gas savings. That was wrong — re-reading EIP-2200/2929, no-op SSTOREs (`prev == new`) cost only 100 gas warm / 2200 gas cold, not the ~2900 of an `nz->nz`. Actual savings ~2.1k gas/game. Not worth the complexity. - - **BC.slot0 / BC.slot1 shadow (effect counts).** Slots 0/1 pack `validator + packedP0EffectsCount` and `rngOracle + packedP1EffectsCount`. 7 writes/game (effect adds) vs 197 reads/game (every effect-list iteration consults the count). To make writes shadow-safe, reads must route through the shadow too (otherwise mid-batch reads see stale counts). At ~110 gas/TLOAD-check × 197 reads = ~22k legacy regression vs ~14k batched savings. Net negative. - - **Effect-data slot shadow (full transient mirror per effect lane).** Hypothesis: per-mon effect data slots get written multiple times per batch (counter bumps in ALWAYS_APPLIES effects, status-degree updates). Implemented a transient `_shadowEffectData[player][mon][slot]` mirror with a per-lane dirty bitmap, routed all `p[01]EffectsData` reads/writes through `_loadEffectDataSlot` / `_storeEffectDataSlot`, and flushed dirty lanes at end-of-batch. Realistic 14-turn steady state moved 292 SLOADs (warm, ~29k) and 21 no-op SSTOREs (~2k) into transient — total measurable storage savings ~31k. But the per-iteration TLOAD-check on `_isEffectLaneDirty` (paid every effect read regardless of shadow state) added ~190k of overhead, and the legacy single-tx harness regressed from 1,867,567 → 1,914,298 (+47k), batched-execute from 1,762,241 → 1,919,712 (+157k). Root cause: on the realistic profile most effect slots are written 1-2× per batch, not 5+, so write coalescing doesn't recoup the read-side TLOAD tax. Same shape as the BC.slot0/1 rejection above — pattern: shadows of slots with high read-to-write ratios are net negative. Reverted in entirety; would only pay off on an effect-heavy profile (status-stacking, multi-effect mon-locals) that the realistic benchmark doesn't exercise. -- **Diminishing returns going forward.** The remaining hot slots are effect mappings (`p0Effects[mon][eff].slot0/slot1` reads) — already amortized via warm-slot caching within the single `executeBuffered` tx. The next real lever would be a structural change: a per-batch cached `EffectInstance` array in transient (read all live effects once into memory, iterate from memory across sub-turns, flush deltas at end). That's a much bigger refactor than the field-level shadows above; queued for a future tier if a profile of an effect-heavy game shows it's worth it. - -### Phase 1 (single-sig + compute-side trace) - -- **Drop committer signature in dual-signed flows.** `executeWithDualSignedMoves` and `submitTurnMoves` now identify the committer by `msg.sender` instead of by an explicit signature. The unilateral-revealer attack (revealer picks any preimage P*, signs `keccak(P*)` as the committer's hash) is closed by `msg.sender == committer`. Trade-off: loses the "anyone can publish with both sigs" relayer property for the committer side (the revealer's sig still lets them be offline at submit time). Per-turn savings on the realistic 14-turn steady-state game: legacy ~3.7k/turn (~52k/game), batched ~6.3k/submit (~88k/game). Production batched-vs-legacy gap widens from ~390k to ~426k (~15.5% per game). - -- **Deep gas trace via per-region instrumentation.** Added temporary `GasProfile` event with 14 per-region transient counters accumulated across the 14-turn batched flow. Emitted at end of `executeBatchedTurns`. Findings: effects dispatch (RoundStart + AfterMove × 4 + RoundEnd) = **47% (843k of 1.86M)**, `_handleMove` = **35% (628k)**, framework overhead (decode + reset + flush) = **2% (37k)**. Compute-side is at or near the floor for the existing game semantics — the remaining costs are real game work (damage calc, type lookup, effect contract calls). - -- **`_handleEffectsTriple` fusion.** RoundStart and RoundEnd each call `_handleEffects` three times (global + priority-mon + other-mon). Fused into a single function frame with identical semantics. Saved ~7k/game (~3.4k each on R3 + R8). Smaller than estimated because IR optimizer + via_ir already inlines internal calls aggressively; the win is just the redundant stack-frame setup the optimizer couldn't fold. AfterMove's 2-call pattern (per-mon + global, interleaved with `_inlineStaminaRegen`) NOT fused — different shape, less payoff. - -- **Adopted: function-frame active-mon-index coalescing (estimate revisited; safety-corrected).** Initial pass dismissed this as worth only ~3-7k. Actual measurement on the realistic 14-turn steady-state shows batched -126k (-7.2%) and legacy -112k (-6.0%). Underestimate root cause: each `_getActiveMonIndex(battleKeyForWrite)` call expands (in shadow mode) to three TLOADs (`_batchShadowActive`, `_shadowBattleSlot1Loaded`, `_shadowBattleSlot1`) plus the bit-shift inside the helper, plus a stack frame the IR optimizer couldn't fold across distinct call points — ~300-500 gas per call, not just one TLOAD. **Switch-safety constraint:** `HardReset` (in `src/mons/nirvamma/HardReset.sol`) is `IMoveSet, BasicEffect` with an `onAfterMove` hook that calls `engine.switchActiveMon` — so coalescing across an effect-lifecycle external call would silently produce stale active-mon indices for subsequent iterations / branches. Hoist sites adopted are only those where: - (a) the cached value is consumed entirely before any external call that could reach `switchActiveMon`, or - (b) the call sequence is pure compute / internal-only. - Adopted: `_runEffects` (3→1 reads at function top; matches the legacy contract that already cached across loop iterations — documented with a comment that effects must not rely on the passed-in indices staying fresh after a mid-loop switch), `_computePriorityPlayerIndex` (2→1), `_checkForGameOverOrKO` (4→1), `_executeInternal` turn-0 ability activation (2→1 — safe because no `IAbility.activateOnSwitch` implementation calls switchActiveMon and HardReset is an `IMoveSet`, not an ability), `_executeInternal` RoundEnd inline stamina regen (2→1 — `_inlineStaminaRegen` is internal-only), `_addEffect` onApply (2→1 — both unpacks complete before the `onApply` external call), `removeEffect` onRemove (2→1 — same shape). **NOT adopted:** `_handleEffectsTriple` cross-branch caching (today RoundStart/RoundEnd effects don't switch, but a future effect bitmapped to those steps + `switchActiveMon` would silently break the hoist — defensive depth via per-branch reads). Snapshot suites improved across the board: `FirstBattle/SecondBattle/ThirdBattle` -112k each (-3.3% to -4.1%), `Fast_Battle1/2/3` ~-92k each (-4.2%), `StandardAttackPvP Turn0_Lead` -10k (-10%), per-turn attacks ~-1.8k each. - -- **Skipped: preload effects into memory array.** Theoretical max savings ~30-40k/game (replace 402 warm-SLOAD effect reads with memory reads). Implementation requires write-through to a memory cache from `addEffect` / `removeEffect` / `_updateOrRemoveEffect` to maintain coherency, plus a sparse memory layout to avoid 50KB+ memory-expansion costs on the cache structure. Complexity-to-savings ratio doesn't pencil — the cached reads are already warm SLOADs (100 gas), and the population/maintenance cost ate most of the win in back-of-envelope. Queued for revisit if an effect-heavy benchmark moves the math. - -- **Net post-trace deltas to the realistic batched steady-state production estimate:** legacy ~2.78M → ~2.78M (unchanged), batched-total ~2.42M → ~2.33M (~3.7% additional savings from single-sig + fusion). Batched saves ~430-450k vs sequential legacy per 14-turn game (~16% production gap). - -### Phase 1 (post-H sweep: more `_readBattleSlot1Packed` coalescing) - -- **`_executeInternal` BD-slot-1 top-of-frame coalesce.** Replaced 3 separate `_getWinnerIndex` / `_getTurnId` / `_getPlayerSwitchForTurnFlag` calls + the `_setPrevPlayerSwitchForTurnFlag(... _getPlayerSwitchForTurnFlag(...))` RMW with one `_readBattleSlot1Packed` + local extracts + one combined RMW write. Each helper internally re-reads the packed slot (3 TLOADs in shadow mode + stack frame), so coalescing saves ~3 reads per `_executeInternal` invocation. Safe to cache here: no external calls run between this block and the setPrev write (just a `_turnP0/P1MoveEncoded` transient check and the `cameFromDirectMoveInput` derivation). The line-590 `_getPlayerSwitchForTurnFlag` (after the engineHooks loop) stays as a fresh read since hooks could mutate slot 1. - -- **`_handleMove` turnId cache.** `_handleMove` reads `_getTurnId(battleKey)` twice (lines 1774, 1794). turnId is only bumped at the end of `_executeInternal` after every `_handleMove` call has returned, so it's invariant across the entire `_handleMove` frame. Cached once at function entry. ~2 calls/turn × 14 turns × ~1 saved read each. - -- **Combined incremental measurement on realistic 14-turn steady state:** batched -19,757 gas (-1.2% incremental, -8.3% cumulative from the original 1,762,241 baseline → 1,615,722); legacy -16,598 gas (-0.9% incremental, -6.9% cumulative from 1,867,567 → 1,738,467). All snapshot suites improved another ~1k-18k per scenario. All 533 tests pass including HardReset's 4 switch-effect tests. - -- **Audit pass exhausted for `_readBattleSlot1Packed`.** Remaining call sites are either single-call-per-function-frame (no in-frame coalesce target) or cross-effect-call boundaries where re-reading is required for correctness (e.g. `_handleEffectsTriple` per-branch `_getWinnerIndex` — effects can KO mons and change the winner mid-call; `_executeInternal` line 590 — engineHooks can mutate slot 1). - -### Phase 1 (post-H sweep #2: cache `battleKeyForWrite` per frame) - -- **TLOAD-coalescing for `battleKeyForWrite`.** Every `_getActiveMonIndex(battleKeyForWrite)`, `_getWinnerIndex(battleKeyForWrite)`, and similar BD-slot-1 helper invocation re-TLOADs the transient `battleKeyForWrite` field (~100 gas) before doing its own slot read. Across the hot path that adds up. `battleKeyForWrite` is set exactly once per external entry and never re-written by internal code (only the external entry points mutate it, and we're past entry), so caching as a local at function top is safe. Where the function already has `battleKey` as a parameter (set to `battleKeyForWrite` at the entry site), substituted directly without an extra local. - - Coalesced sites: - - `_executeInternal` (4 redundant battleKeyForWrite reads → use the `battleKey` function param). - - `_handleMove` (3 reads in different code paths → 1 local `bkw`). - - `_dealDamageInternal` (3 reads across game-over check, PreDamage dispatch, AfterDamage dispatch → 1 local `bkw`). - - `_checkForGameOverOrKO` (2 reads → 1 local `bkw`). - - `_handleEffectsTriple` (5 reads across global + priority + other branches → 1 local `bkw`). - - `_handleEffects` (2 reads → 1 local `bkw`). - - `_runEffects` (1 read → use `battleKey` param). - - `_handleSwitch`, `_addEffectInternal`, `_removeEffectAtSlot`, `dispatchStandardAttack`, `switchActiveMon`, `_computePriorityPlayerIndex` (1 redundant read each after their existing battleKey cache). - - Realistic 14-turn steady-state incremental: batched -25,624 (-1.6%), legacy -25,624 (-1.5%). All 533 tests pass including the 4 HardReset tests. - - **Cumulative vs original baseline (pre-H, pre-batched-decoupling-sweep):** batched 1,762,241 → 1,590,098 = **-172,143 gas (-9.8%)**; legacy 1,867,567 → 1,712,843 = **-154,724 gas (-8.3%)**. - -### Phase 1 (post-H sweep #3: pack per-turn move/salt transients into one slot) - -Four separate transient slots (`_turnP0MoveEncoded`, `_turnP1MoveEncoded`, `_turnP0Salt`, `_turnP1Salt`) each took their own TSTORE on write and TLOAD on read. They're always set/cleared together so they can share one packed `uint256 _turnTransient` slot: - -``` -[0..7] p0 packedMoveIndex (storedMoveIndex | IS_REAL_TURN_BIT) -[8..23] p0 extraData -[24..127] p0 salt -[128..135] p1 packedMoveIndex -[136..151] p1 extraData -[152..255] p1 salt -``` - -Exactly 256 bits. Per-side `IS_REAL_TURN_BIT` preserved so `_getCurrentTurnMove` / `_getCurrentTurnSalt` can still detect "this side's transient is populated" and fall back to storage when not — DefaultCommitManager's `execute(battleKey)` flow keeps working unchanged. - -Per-call effect: -- `executeWithMoves`, `executeWithSingleMove`, `executeBatchedTurns` per iter: 4 TSTOREs → 1 TSTORE. -300g/call. -- `executeBatchedTurns` inter-iter reset: 4 → 1 TSTORE. -300g/iter. -- `setMove` mid-execute (Sleep override): now TLOAD + RMW + TSTORE instead of plain TSTORE. +200g per sleep-tick. Rare; net positive. -- The IR optimizer now inlines and packs the read paths tighter, yielding additional bytecode-level wins on top. - -**Measured (realistic 14-turn steady-state + B=14 CPU batched):** - -| | Pre-pack | Post-pack | Δ | +| Production estimate | ~3.49M | ~2.53M (**-960k, ~-28%**) | + +### PvP legacy dual-signed (B=14) +- ~3.2k/turn from engine-direct entry (skipping manager STATICCALL). +- ~3.7k/turn from single-sig (~52k/game). +- Shadow + slot-1 coalescing + dropped event: ~4-5k/turn additional. +- Production batched-vs-legacy gap (after single-sig): ~426k/game (~15.5%). + +### Realistic 14-turn steady-state (production access pattern) +- **Batched − legacy = -35 SSTOREs / -936 SLOADs/game.** + Approximately 100k saved on SSTOREs + 94k saved on SLOADs = ~200k batched advantage + per game vs legacy baseline. +- Per-slot proof of shadow batching: + - BD.slot1: 14 writes → 1 (single flush) + - BC.slot2 `koBitmaps`: ~5 writes → 0 (folded into one already-needed slot write) + - MonStates: ~6 writes → 0 (game-over flush skip) + +### Harness caveat +The single-tx foundry harness measures all 14 turns under one EVM tx; per EIP-2929, slots +accessed in turn 1 become warm for turns 2-14.

StatBoosts (always 256 bits because of its 168-bit identity key) takes the external slot 1 path; everything else fits inline. - -Implementation prototype (commits `0bfea95` + `6ba4a9a`) used inline assembly for the hot dispatch read in `_runEffects` (Yul `switch` gating the slot 1 SLOAD) and helper functions for writes. Realistic 14-turn steady-state delivered: - -- Storage access tally improvement: SLOADs 972 → 859 (-113, of which -8 cold + -105 warm), SSTOREs 51 → 42 (-9, mostly no-op eliminations). +5 cold SSTOREs offset by -8 cold SLOADs — the cold penalty just moved from SLOAD to SSTORE (same 2100g cost). -- **Theoretical storage savings: ~17.7k.** Measured total savings: ~3.5k. -- **Implied runtime compute overhead: ~14k**, despite Engine bytecode actually *shrinking* by 174 bytes. Sources: branch + bit-extract in dispatch (~3k), function-call frames in write helpers (~1.5k), casts/wraps that pre-tiered struct field access optimized away (~1-3k), unattributed IR-optimizer global re-balancing (~5-9k). -- Bucket inspection of the realistic profile showed **zero real writes to effect slots during execute** (all SSTOREs were no-ops via MappingAllocator slot reuse since battle 2 reruns battle 1's plan), and **~50% of dispatched effects were StatBoosts** (external path, no inline benefit). The write-side savings — the largest theoretical win of tiered storage — was completely unmeasured. - -Reverted because the ~3k/game execute-side benefit didn't justify ~150 LOC of assembly + helpers, especially when most of the production-realistic profile (StatBoosts-heavy) doesn't benefit. The cleaner caching/coalescing wins from the previous phases are the right shape for this codebase: they remove redundant TLOADs at zero compute cost. Tiered storage trades storage cost for compute, and on this profile compute already dominates. - -Don't redo this without first changing the profile (status-DOT-heavy games, or shrinking StatBoosts' identity key to fit in 79 bits) or finding a way to dispatch without the per-effect branch (only feasible if all effects' data fits inline). +--- +## Lessons (worth applying to v2) + +1. **Warm-slot semantics deliver most of the cold-storage amortization for free.** Inside + a single tx, the second-and-later iterations of `executeBuffered`'s sub-turn loop see + slots from earlier turns as warm.

From 88164147451fb2f2f617338d27ffb3ae5cd379fa Mon Sep 17 00:00:00 2001 From: Claude Date: Sun, 24 May 2026 23:45:49 +0000 Subject: [PATCH 59/65] opt(engine): per-field MonState reads bypass full unpack on legacy path MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Adds two helpers that skip the 9-field memory unpack \`_loadMonState\` performs: - _readMonStateDelta now operates directly on the packed slot from _readMonStatePacked (shift+mask per field, sentinel→0 conversion preserved). Used by the public getMonStateForBattle, so external move callers benefit too. - _isMonKnockedOut: dedicated single-bit check for the hot KO-guard pattern. Saves ~220g/call vs _loadMonState(...).isKnockedOut. Migrated 10 single-field _loadMonState callsites: - 8× .isKnockedOut → _isMonKnockedOut - 2× .speedDelta in _computePriorityPlayerIndex → _readMonStateDelta(...,Speed) (also removes the now-redundant CLEARED_MON_STATE_SENTINEL check at the call site since the helper sanitizes internally) Multi-field _loadMonState callers (10+ remaining) keep the existing load-modify-store pattern — they amortize the unpack across multiple fields. Snapshot deltas vs main: recovers 25-30% of the legacy-path regression introduced by the MonState shadow refactor. EngineGasTest B1_Execute went from +69k (+7.6% vs main) to +50k (+5.4%); FirstBattle from +290k (+9.9%) to +218k (+7.5%); BetterCPU Turn1 from +33k (+13.7%) to +20k (+8.2%). Residual ~5-10% gap vs main is infrastructure cost the legacy path can't escape without a full execute-internal split: TLOAD-check tax in _readMonStatePacked (~100g × ~250 calls/game), BD slot-1 helper-routing, and the dispatch-table cost of the new external entrypoints. Phase B2 (per-field MonState write helpers for the write-heavy frames) is the next lever if more recovery is needed.

Refactors _updateMonStateInternal to skip the 9-field memory unpack/repack for the 8 numeric/bool branches it already special-cases: - Hp/Stamina/Speed/Atk/Def/SpAtk/SpDef → _addToMonStateDeltaField: direct packed RMW with sentinel-as-zero semantics. Saves ~410g per call vs the load-modify-store pattern through _loadMonState. - ShouldSkipTurn → _setShouldSkipTurn: single-bit flip on the packed slot. IsKnockedOut keeps the full-unpack path — its KO-bitmap + winner-check + OnUpdateMonState side effects are intertwined with the in-memory struct mutation, so factoring it out for a few hundred gas isn't worth the restructuring. Snapshot deltas vs pre-B2 (B1 baseline 8816414): EngineGasTest FirstBattle 3,138k → 3,128k (-10k) EngineGasTest SecondBattle 3,193k → 3,180k (-13k) EngineGasTest ThirdBattle 2,510k → 2,500k (-10k) InlineEngine B1_Execute 937k → 935k (-2k) InlineEngine FirstBattle 2,771k → 2,761k (-10k) Per-execute hot paths in EngineGasTest/BetterCPUInlineGasTest unchanged because the mock attacks they exercise don't call engine.updateMonState. Savings appear on battle-lifecycle paths (KO handling, stamina regen) and on the Inline harness's Battle setups. Total recovery vs main (B1+B2 combined): ~25-30% of the legacy-path regression. Residual ~5-9% gap vs main is the architectural cost of the shadow infrastructure on the legacy code path (TLOAD-check tax in _readMonStatePacked, BD slot-1 helper-routing, new dispatch entries) — recoverable only via Option A (parallel execute internals).

All three are the same packed slot; each was a separate SLOAD because the helpers couldn't be deduplicated across function call boundaries by the optimizer. Read the slot once into `slot1Packed`, extract `turnIdCached` and `cachedPackedActiveMon` via bit shifts, and reuse both for the attacker and defender mon reads in both the INLINE and EXTERNAL paths. Safety: the cache is only consumed pre-external-call. Mutation barriers inside _handleMove are: - moveSet.move(...) / _inlineStandardAttack → PreDamage effects: these can call engine.switchActiveMon (PistolSquat / HitAndDip / RoundTrip do this) — but the cached values were already consumed by then. - _handleSwitch (in the SWITCH branch): writes slot1, called after the cache has been used. - moveSet.stamina() and validator.validateSpecificMoveSelection() are read-only by interface contract — treated as safe.
