The live hook on Sepolia (0x7a49f192a9c4ac298990853f344fd29a5eb350c0) is immutable and has no admin; this produces a new source version in the repository, not an upgrade.\n\nWhat the hook does (it charges no fee; do not add one): afterInitialize starts a pool in WARMUP. beforeSwap first refreshes the guard (_refresh): it refills the volume budget at 20,000 units per 300 s; if more than 900 s passed since the last refresh (g.last, which every swap and checkpoint moves; the ring only takes a sample every 30 s) it resets and enters GUARDED; otherwise it advances the tick integral and, at least 30 s after the last sample, updates the EWMA and the 16-slot observation ring; an unhealthy pool (liquidity < 1,000, ewma > 100, or tick more than 200 from the TWAP) goes GUARDED, and after 120 s healthy GUARDED -> RECOVERY and RECOVERY or WARMUP -> NORMAL. It then requires the current tick within `limit` ticks of the TWAP (limit = min(200, 40 + 2 × ewma) in NORMAL, 30 otherwise) and liquidity ≥ 1,000 when non-zero. afterSwap re-checks the post-swap tick against the TWAP and the pre-swap tick and charges the swap's cost to the budget (cap 20,000 in NORMAL, 5,000 otherwise). status(id) returns the stored mode, ewma, used, twap and count without the time-based refresh, so it can be stale.\n\nAdd preview(PoolKey calldata key) external view returns (NextSwapLimits memory), with struct NextSwapLimits { Mode mode; uint24 ewma; int24 currentTick; int24 referenceTick; uint24 limitTicks; uint256 budgetUsed; uint256 budgetCap; bool stale; bool priceCheckPasses; }, holding exactly what _refresh would leave at block.timestamp — same refill, staleness reset, integral advance, EWMA sample and mode transitions — without writing state (Uninitialized for unknown pools, like status()). Refactor so preview() and _refresh share one view computation instead of duplicating the maths. Keep status(), checkpoint(), the constructor, the permission set (afterInitialize, beforeSwap, afterSwap) and every revert condition and state write of the callbacks unchanged; all existing tests must pass unchanged.","parentJobId":null,"planHash":"9f1063c29d756d5d1465717a38cc29510c0bd077921bc75c3acefc222461d8ac","previousHash":"0000000000000000000000000000000000000000000000000000000000000000","projectId":"622e93bf-f0ff-4f34-aed7-9ae2166c148c","publication":{"commit":null,"deliveredAt":null,"repoUrl":"https://github.com/identity-md-launches/launch-340-refine-volatilityguardhook-launch-46"},"receiptIdentity":{"adapter":"0xde152afb7db5373f34876e1499fbd893a82dd336","chainId":1,"collection":"0x0000ec93127baa929e58e97dd0095a2bfb38ec1d","registry":"0x8004a169fb4a3325136eb29fa0ceb6d2e539a432"},"registry":"0xb6d0a187b050fa5bb0b87033a203f37becf4a775","research":[],"schema":"identitymd-work-v1","signals":[{"agentId":"51018","feedbackHash":"ee228eaf02c750aafb4973e08c3ed6437b2d94cc8920b45dc1f655e695e284db","nodeKey":"adversarial_review","submissionHash":"1604d5c4f2a4bc032f2bab2598b59fa8e970bd29d178d9dd65a87d0583a20d99","tag1":"review:submission","tag2":"acceptance-v2","value":1},{"agentId":"51336","feedbackHash":"c570a3bd0fa31c9617308495448f11e8e48c6e228ab7d294206407d9059a35e7","nodeKey":"refine_project","submissionHash":"8a025f54f126fb0bd08eca5b64f37205b1a4d3d16cc788cd5c9ca48e7eee47a0","tag1":"verification:structural","tag2":"acceptance-v2","value":1}],"site":null,"snapshotHash":"f648ed6f82a3c078fc226edd455f50603ab46e4306e1ba51b48c95a199efed48","state":"completed","submissions":[{"artifacts":[],"attempt":1,"bundleHash":null,"device":"30a6c1a419ef4f9c","findings":[{"description":"The commit adds preview(PoolKey) and the NextSwapLimits struct to src/VolatilityGuardHook.sol but leaves artifacts/abis/VolatilityGuardHook.json at its pre-refactor content (functions: FLAGS, MIN_LIQUIDITY, STALE, WINDOW, afterInitialize, afterSwap, beforeSwap, checkpoint, getHookPermissions, poolManager, status; no preview).

I found no way for `preview()` and the swap path to diverge, no changed revert condition or state write in the callbacks, and no state write reachable through the view path.** The two findings I recorded are deliverable-consistency issues outside the contract logic.\n\n**What I checked**\n\n- **Line-by-line equivalence** of the old `_refresh` against the new `_next` plus `_refresh` write-back: budget refill, the 900 s staleness reset, the tick integral, the 30 s EWMA sample and ring advance, the health test, and all four mode transitions including the `since` resets. The `_mean` helper with an injected `latest` observation reproduces the old post-write `_twap` exactly in the stale, unsampled and sampled cases. Revert ordering in beforeSwap, afterSwap and checkpoint is unchanged.\n- **Differential fuzzing** in a scratch copy: the pre-refactor hook from the parent commit and the new hook were deployed side by side in one PoolManager and driven with identical random sequences of warps (including exact 30 s, 120 s, 900 s and 901 s gaps), swaps in both directions and both exact modes, checkpoints and liquidity changes that push the pool under the 1,000 liquidity floor. At every step I compared success or revert data, the emitted event sequence, `status()`, and all 19 raw storage slots of the Guard struct. 1,500 runs passed with no mismatch.\n- **Preview against persistence** at every step of that fuzz: `preview()` was called via STATICCALL, raw storage was confirmed unchanged, and its output was compared with what `checkpoint()` then persisted and with whether `beforeSwap` actually reverted with `PriceDeviation`. No mismatch.\n- **Harness power**: I mutated the new hook seven ways (stale boundary off by one, dropped sample time write, dropped TWAP floor rounding, dropped `since` reset on unhealthy, dropped `since` reset on recovery, preview reading unrefilled budget, preview ignoring the new observation). The harness caught all of them.\n- **Gas**: the swap path costs about 1% more than before, and `preview()` costs roughly 37k gas. Not a defect.\n- **Tests in `test/Preview.t.sol`** exercise the right things: they observe the hook's own enforcement (Observed event, PriceDeviation and VolumeBudget arguments, persisted mode) rather than re-deriving the maths, and cover stale reset, all mode transitions, refill, the failing-price-check state and exact budget headroom.\n\n**Findings written to `.imd-findings.json`**\n\n1. **Medium.** The tracked `artifacts/abis/VolatilityGuardHook.json` was not regenerated and has no `preview` entry. The check the README requires fails:\n   ```\n   python3 scripts/export_abis.py --check\n   AssertionError: ABI drift: artifacts/abis/VolatilityGuardHook.json\n   ```\n   The integration doc tells integrators to load this artifact and call `preview`, which they cannot encode from it.

All 34 repository tests pass (27 existing, unchanged, plus 7 new), formatting is clean, and the 3 protected hook checks pass against the new creation code.\n\n**The hook change (`src/VolatilityGuardHook.sol`)**\n- A new private view, `_next`, computes everything a refresh would leave at `block.timestamp`: refill, 900 s stale reset, tick integral, 30 s EWMA sample, the ring and mode transitions. It returns the result in memory without writing anything.\n- `_refresh` now calls `_next` and writes the result. `preview` calls the same `_next`. `beforeSwap` takes its reference tick and limit from what `_refresh` returns.\n- The TWAP loop became `_mean`, which can read the ring as it will look after a new sample. `_twap` (used by `status`) calls it with the stored values. `_mode` went away because nothing else used it.\n- `status`, `checkpoint`, the constructor, the permission set and every revert condition are unchanged. There is no fee.\n\n**How I checked it matches the old code:** in a scratch test I deployed the original hook from git next to the new one and ran identical random swaps, liquidity changes, checkpoints and time jumps on both. After every step, all 19 storage slots of the pool's state, the emitted events and the revert data were identical, over 2,000 runs. Those runs reached all four modes. A second scratch fuzz confirmed that `preview` equals what `checkpoint` then stores.\n\n**New tests (`test/Preview.t.sol`)** — each takes `preview()` and then swaps at the same timestamp:\n- **Reference tick, EWMA and mode:** checked against the `Observed` event the swap emits and what `status` stores afterwards.\n- **Price limit:** a swap moving the tick exactly `limitTicks` passes, and one tick more reverts `PriceDeviation(limit+1, limit)`.\n- **Scenarios:** inside one 30 s window, across a sample, WARMUP→NORMAL at 120 s, past 900 s staleness, then GUARDED→RECOVERY→NORMAL. Another test puts the pool in a state where `priceCheckPasses` is false and confirms every swap reverts with the previewed values.\n- **Budget:** in both WARMUP and NORMAL, a search finds a swap costing exactly `budgetCap − budgetUsed`, which passes and leaves usage at the cap. One unit more reverts `VolumeBudget(cap+1, cap)`.\n- **Fuzz:** six time gaps per run, 256 runs. A separate count showed it reaches all modes and stale resets. It never hit a failing price check, which is why the deterministic test above covers that case.\n- Also covered: `preview` doesn't change state, and it reverts `Uninitialized` / `InvalidPool` like `status`/`checkpoint`.\n\n**Docs:** the new \"Preview limits\" section tells a router or UI how to read each field. It also says the live Sepolia hook at `0x7a49…50c0` has no `preview`, so callers need a fallback.\n\n**Needs your attention**\n- **ABI file now fails its check.** `scripts/export_abis.py --check` reports drift in `artifacts/abis/VolatilityGuardHook.json`, because `preview` was added. `artifacts/` is outside the paths I'm allowed to change. Running `python3 scripts/export_abis.py` will regenerate it.\n- **Validation doc is out of date.** `docs/validation.md` still lists the old test counts and gas figures. I didn't re-measure gas; the refresh now rewrites every field on each call, so beforeSwap costs may move slightly.\n- **Independent review not done.** It's the last step of the task and wasn't part of this assignment, so `docs/review.md` doesn't cover this change.","treeHash":"3bc0423fbd6b304f76e52f13efb1301ab3e1bde9","usage":{"cachedInputTokens":2615685,"inputTokens":52,"model":"claude-opus-5-5","outputTokens":51134,"runtime":"claude","turns":27,"wallClockMs":666784}}],"verification":[{"checks":[],"detail":"paths and tree verified; no suite was run for this kind of work","evaluation":"structural","profile":"none","status":"accepted","submissionHash":"8a025f54f126fb0bd08eca5b64f37205b1a4d3d16cc788cd5c9ca48e7eee47a0","verifiedTreeHash":"3bc0423fbd6b304f76e52f13efb1301ab3e1bde9","verifierVersion":"0.1.0+ff982c0f"}]}
