Subject: [PATCH 01/10] Add replay batch recording, perturbation hook, and
 deterministic iteration

- ReevaluationRunner --record: headless batch recording with deterministic
  MoveTo injection; seed via landID
- MovementSystem: env-driven perturbation hook (HERO_PERTURB_*) for the
  replay sensitivity experiment; inert when unset
- Fix order-dependent game logic: sorted-key iteration over players/
  monsters/turrets and lowest-id tie-break in nearest-target selection.
  Dictionary iteration order made 1,200-tick replays diverge (28/30
  failed); 30/30 verify cleanly after the fix
- Runner: re-check server-event mismatches by content, reporting pure
  sequence-numbering differences (known replay accounting gap) as a
  warning instead of a failure

+# Experiment design: replay verification at scale + FP perturbation sensitivity
+
+Design run under `sst-experiment` (step 2b). Topic: `deep-research/replay-scale-fp-perturbation/`.
+Card approved by the maintainer in chat on 2026-08-31. Everything in this round (knobs, this
+note, data) lands via the `experiment/replay-scale-fp-perturbation` PR.
+
+## Question
+
+(A) Over dozens of recordings and tens of thousands of ticks, does per-tick hash replay
+verification stay at 0 mismatches? (B) When a floating-point / fixed-point perturbation is
+injected into replay, does the verification detect it, and with what latency in ticks?
+
+## Design decisions
+
+### D1: Headless batch recording — `ReevaluationRunner --record`
+
+**Chosen:** a new `--record` mode runs an in-process live `LandKeeper` with
+`enableLiveStateHashRecording`, joins 5 players, injects a deterministic `MoveTo` client
+event per player every 20 ticks (integer-math targets, same style as the EncodingBenchmark
+`--active-players` injector), steps N ticks, and saves via `ReevaluationRecorder.save`.
+`landID = "hero-defense:batch-<seed>"` — the RNG seed is derived from the landID, so each
+seed index yields a distinct recording.
+
+**Rejected:** looping the WebSocket E2E recorder against a live GameServer — orders of
+magnitude slower, adds transport nondeterminism unrelated to the question, and cannot run
+30 recordings unattended in reasonable time.
+
+**Why this answers the Question:** live-mode `LandKeeper` records injected actions/client
+events and per-tick hashes exactly as the server path does; replaying these records through
+`ReevaluationEngine` is the same verification the paper describes, now at ~30 × 1,200 ticks.
+
+### D2: Perturbation hook — env-driven, inside `MovementSystem.updatePlayerMovement`
+
+**Chosen:** three env vars (read once per process), `HERO_PERTURB_TICK`,
+`HERO_PERTURB_MODE` (`float` | `fixed`), `HERO_PERTURB_EPS`. At the configured tick, every
+player currently moving gets perturbed: `float` adds eps to the Float `moveSpeed` before
+fixed-point quantization; `fixed` adds eps raw LSB units (1 LSB = 0.001 world units) to the
+quantized x coordinate after the movement step. Unset env = hook fully inert (recording and
+normal replay are untouched).
+
+**Rejected:** a perturbation flag inside `ReevaluationEngine` (core `Sources/`, would need a
+core PR and couples the engine to an experiment concern); patching the record file itself
+(tests the parser, not the determinism pipeline).
+
+**Why this answers the Question:** the reviewer objection is about sensitivity to FP
+non-determinism in game logic. Perturbing the actual movement computation during replay is
+exactly that failure mode; sub-LSB float noise vs >=1 LSB shifts separates "absorbed by
+fixed-point quantization" from "detected by hash comparison".
+
+### D3: Metric semantics (mandatory)
+
+- Part A, per recording: `total_ticks` = maxTickId+1; `mismatch_ticks` = count of ticks where
+  the replayed hash differs from the recorded ground-truth hash (second check: run1 vs run2
+  of the replay); `total_actions` / `total_client_events` from record statistics. One unit =
+  one tick compared.
+- Part B, per (recording, eps) cell: `detected` = verification exited with >=1 recorded-hash
+  mismatch; `detection_latency_ticks` = first mismatched tickId − perturb tick (600); null
+  when not detected. One unit = one perturbed replay run.
+- All runs `swift run -c release`; runner stdout kept as `results/<run-id>.log`.
+
+### D4: Matrix
+
+| Part | axis | values |
+|---|---|---|
+| A | seed | 1…30 (landID-derived), 1,200 ticks each |
+| B | eps | float 1e-7 (sub-LSB), fixed +1 LSB, fixed +1000 LSB | 
+| B | recordings | seeds 1…10, perturb tick 600 |
+
+Fixed: 5 players, MoveTo every 20 ticks, no turrets, single room, same host (Apple M2, arm64).
+
+## Risks
+
+- Same-architecture only this round (arm64 record → arm64 replay); the 2026-02 evidence
+  already covers arm64 → x86_64. Stated in Caveats.
+- Sub-LSB float perturbation may be absorbed (0 detections) — that is a result, not a failure.
+- If players are not moving at tick 600 the perturbation is a no-op; the 20-tick MoveTo
+  cadence with far targets keeps all players moving throughout.
+
+## Findings during execution (2026-08-31)
+
+1. **Replay sequence-counter gap.** Re-evaluation replays recorded inputs with their recorded
+   sequence numbers but never advances the shared output-sequence counter past them, so server
+   events emitted during replay carry different `sequence` values than the recording even when
+   state evolution is identical. The runner now re-checks such mismatches by content (tickId,
+   type, payload, target) and reports a pure sequence difference as an explicit warning instead
+   of a failure. A core fix (advancing the counter during replay) is tracked as follow-up work.
+2. **Order-dependent game logic (real determinism bug, found by scaling).** The first full run
+   failed 28/30: replays diverged from recordings at scattered ticks, and one seed even diverged
+   between two replays in the same process. Field-level diff at the first divergent tick showed
+   players' `lastFireTick`/`rotation`/`resources` differing — firing order and target selection
+   depended on `Dictionary` iteration order (`for (id, x) in dict` in the tick handler, and a
+   strict `<` nearest-target comparison that broke ties by iteration order). Fix: sorted-key
+   iteration for players/monsters/turrets and a lowest-id tie-break in
+   `CombatSystem.findNearestMonsterInRange`. After the fix: 30/30 recordings verify with zero
+   mismatches. The five short recordings used previously never surfaced this because sparse
+   combat rarely hit an order-dependent branch.
+3. The pre-existing committed fixtures (`reevaluation-records/1..3-hero-defense.json`, January)
+   no longer replay against current game logic — expected staleness, they are not used by tests.

Subject: [PATCH 02/10] Add replay-scale-fp-perturbation experiment results

30 recordings x 1,200 ticks: 0 hash mismatches, run1 == run2 for all.
Perturbation at tick 600: sub-LSB float noise absorbed 10/10 by
fixed-point quantization; >=1 LSB shifts detected 10/10 with 0-tick
latency.

+# Replay verification at scale + FP perturbation sensitivity
+
+## Question
+
+(A) 大規模重播驗證（數十段錄音、上萬 ticks）下，逐 tick state-hash 比對是否維持 0 mismatch？
+(B) 在重播中注入浮點／定點擾動時，hash 驗證能否偵測、偵測延遲幾個 tick？
+
+## Environment
+
+- date: 2026-08-31
+- git_sha: `d23d66d`（`experiment/replay-scale-fp-perturbation` branch；含 `--record` 模式、擾動 hook、與確定性迭代修正）
+- swift_version: Apple Swift 6.3.2, build_config: release
+- host: Apple M2, macOS（8 cores, 16 GB）, arm64（錄製與重播同架構；跨架構證據見 2026-02 evidence）
+
+## Command(s)
+
+```bash
+cd Examples/GameDemo && swift build -c release
+BIN=.build/release/ReevaluationRunner
+
+# Part A: record + verify, seeds 1..30
+$BIN --record --output s<N>.json --seed-id <N> --ticks 1200
+$BIN --input s<N>.json --verify          # exit 0 = hashes match ground truth AND run1 == run2
+
+# Part B: perturbed replay (recordings stay clean; the hook only affects this replay)
+HERO_PERTURB_TICK=600 HERO_PERTURB_MODE=<float|fixed> HERO_PERTURB_EPS=<eps> \
+  $BIN --input s<N>.json --verify
+```
+
+- `--record`：in-process live keeper，5 玩家 join、每 20 ticks 每人注入一個確定性 `MoveTo`
+  client event、1,200 ticks（~60 s @20 Hz），錄下 inputs 與逐 tick state hash。rngSeed 由
+  landID（`hero-defense:batch-<N>`）派生，每個 seed 是不同的一局。
+- 擾動 hook 作用在 `MovementSystem.updatePlayerMovement`：`float` 模式在定點量化前對 Float
+  moveSpeed 加 eps；`fixed` 模式在量化後對 x 座標加 eps 個 LSB（1 LSB = 0.001 world units）。
+- 設計文件：`Notes/plans/2026-08-31-replay-scale-fp-perturbation-experiment-design.md`。
+
+## Parameter matrix
+
+| Part | 軸 | 值 | 固定 |
+|---|---|---|---|
+| A | seed | 1–30 | 1,200 ticks、5 players、MoveTo every 20 ticks |
+| B | 擾動 | float 1e-7 / fixed +1 LSB / fixed +1000 LSB | perturb tick = 600，seeds 1–10 |

+
+## Conclusion
+
+30 段 × 1,200 ticks（36,000 ticks、9,000 個 client events）重播驗證 **0 hash mismatch**，且每段
+run1 與 run2 完全一致；次解析度的浮點擾動（1e-7，量化前）10/10 被定點量化吸收（仍 0 mismatch），
+而 ≥1 LSB 的狀態擾動 10/10 在注入當 tick（延遲 0）被逐 tick hash 比對偵測。亦即：驗證機制對
+「會改變定點狀態的最小擾動」即時敏感，對「低於定點解析度的浮點雜訊」則因量化而免疫。
+
+## Caveats
+
+- **本實驗過程中發現並修正了一個真實的決定性 bug**：hero-defense tick handler 與最近目標選擇
+  依賴 Dictionary 迭代順序，1,200-tick 規模下 28/30 段重播發散（短錄音從未觸發）。修正為
+  sorted-key 迭代與 lowest-id tie-break（commit `d23d66d`）後才有上表結果。此發現本身即為
+  規模化驗證的價值證據，詳見設計文件 Findings。
+- **重播的 server event sequence 編號與錄製不同**（重播不推進共用序號計數器，已知缺口）：
+  Runner 以內容級比對（tickId/type/payload/target）複核，純序號差異降為明示警告；core 修復
+  為後續工作。本表所有 record 的事件內容比對皆通過。
+- 錄製與重播同為 arm64/macOS；跨架構（arm64→x86_64）證據見
+  `deep-research/emse-artifacts/evidence-2026-02-06-*`。
+- 擾動作用於當 tick 所有移動中的玩家（非單一玩家）；latency 以「首個 mismatch tick − 600」計。
+- 錄音檔（每段 ~1200 ticks）未入 repo：由 `--record --seed-id <N>` 可決定性重建。
+- 未變動軸：ticks/段（1,200）、玩家數（5）、注入節奏（20 ticks）、擾動時點（600）、砲塔（0）。

Subject: [PATCH 05/10] Add workload variants, long-horizon runs, and
 cross-arch verify script

9 variant recordings (players 2/10, MoveTo cadence 5) and two 12,000-tick
long-horizon recordings, all 0 mismatches; totals now 41 recordings /
70,800 ticks. crossarch-verify.sh replays the same arm64-recorded batch
on an x86_64 machine.

Subject: [PATCH 10/10] Integrate cross-arch verification into results and
 tables

regenerate.py now tolerates result files without a workload field and
renders the cross-architecture table; README records the 41/41 x86_64
(WSL2, Swift 6.2.3) replay of the arm64-recorded batch.
