- **Bug**: Fix JSON malformation in _snapshotPositions — closing literal was '"}}}' (three
braces) but only '"}}' is needed (close discovery{} + positions{}). The third brace
prematurely closed the root object, making every snapshot unparseable downstream.
- **Nit**: _executeStake local variable renamed taxRateIndex → taxRate to match the
IStake interface and Stake.sol. JSONL field key '.taxRateIndex' is kept for backward
compatibility with existing attack files; the comment and NatDoc header now say so.
- **Nit**: recenter_is_up now emits JSON null (not false) before the first recenter call,
via a new _hasRecentered flag. Downstream parsers can distinguish "no recenter yet"
from "last recenter moved price down" (false). _hasRecentered is set to true alongside
_lastRecenterIsUp in the recenter handler.
- **Nit**: Added a comment to _logSnapshot explaining that pool.slot0() is a view call
and forge-std finalises broadcast state before executing it, so tick/sqrtPrice are
always post-broadcast accurate.

- **Bug**: `_positionEthValue` now sums both the ETH component and the KRK component
(converted to ETH via `FullMath.mulDiv` at current sqrtPriceX96) so `lm_eth_total`
correctly reflects LM TVL for all price ranges (below/in/above range).
- **Bug**: `recenter()` return value (`bool isUp` — price direction) is now captured in
`_lastRecenterIsUp` state variable and emitted as `"recenter_is_up"` in every snapshot.
Note: `recenter()` reverts on failure; `false` means price moved *down*, not a no-op.
- **Bug**: Discovery position now emits `"ethValue"` in its snapshot JSON object,
matching the floor and anchor fields for symmetric automated parsing.
- **Warning**: `IStake.snatch` interface parameter renamed `taxRateIndex` → `taxRate` to
match the actual `Stake.sol` signature (the value is a raw rate, not a lookup index).
- **Warning**: Unknown op codes in the JSONL file now emit a `console.log` warning
instead of silently skipping, catching typos in attack sequences.
- **Nit**: `_setup()` now wraps 9 000 ETH (up from 1 000) to cover heavy buy sequences
that would otherwise exhaust the adversary's WETH.
- **Nit**: `_computeVwapTick` documents the int128 overflow guard and its tick=0 sentinel
meaning so callers can distinguish "VWAP unavailable" from tick zero.

- Fix unsafe int32 intermediate cast: int56(int32(elapsed)) → int56(uint56(elapsed))
to prevent TWAP tick sign inversion for intervals above int32 max (~68 years)
- Remove redundant lastRecenterTimestamp state variable; capture prevTimestamp
from existing lastRecenterTime instead (saves ~20k gas per recenter)
- Use pool.increaseObservationCardinalityNext(ORACLE_CARDINALITY) in constructor
instead of recomputing the pool address; extract magic 100 to named constant
- Add TWAPFallback(uint32 elapsed) event emitted when pool.observe() reverts
so monitoring can distinguish degraded operation from normal bootstrap
- Remove conditional bypass paths in test_twapReflectsAveragePriceNotJustLastSwap;
assert vwapAfter > 0 and vwapAfter > initialPriceX96 unconditionally
Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
- Add lastRecenterTimestamp to track recenter interval for TWAP
- Increase pool observation cardinality to 100 in constructor
- In _scrapePositions, use pool.observe([elapsed, 0]) to get TWAP tick
over the full interval between recenters; falls back to anchor midpoint
when elapsed==0 or pool.observe() reverts (insufficient history)
- Add test_twapReflectsAveragePriceNotJustLastSwap: verifies TWAP-based
VWAP reflects the average price across the recenter interval, not just
the last-swap anchor snapshot

Replace the ethPerToken metric (free balance / adjusted supply) with total
LM ETH (free + WETH + position-locked) using a forge script with exact
Uni V3 integer math. Collapses 4+ RPC calls and Python float approximation
into a single forge script call using LiquidityAmounts + TickMath.
Also updates red-team prompt, report format, memory extraction, and adds
roadmap items for #536-#538 (backtesting pipeline, Push3 evolution).

- _scrapePositions natspec: 'ETH inflow' → 'ETH outflow / price fell or at bootstrap'
- Inline comment above VWAP block: remove inverted 'KRK sold out / ETH inflow' rationale,
replace with a neutral forward-reference to recenter() where the direction logic lives
- VWAPFloorProtection.t.sol: remove unused Kraiken and forge-std/Test.sol imports
(both are already provided by UniSwapHelper)
- test_floorConservativeAfterBuyOnlyAttack: add assertFalse(token0isWeth) guard so a
future change to the setUp parameter cannot silently invert the gap-direction assertion
Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
Investigation findings:
- VWAP WAS being fed during buy-only cycles (shouldRecordVWAP = true on ETH inflow / price rising).
Over 80 buy-recenter cycles VWAP converged toward the inflated current price.
- When VWAP ≈ currentTick, mirrorTick = currentTick + vwapDistance ≈ currentTick, placing
the floor near the inflated price. Adversary sells back through the high floor, extracting
nearly all LM ETH.
- Optimizer parameters (anchorShare, CI) were not the primary cause.
Fix (LiquidityManager.sol):
Flip shouldRecordVWAP from buy direction to sell direction. VWAP is now recorded only when
price falls (ETH outflow / sell events) or at initial bootstrap (cumulativeVolume == 0).
Buy-only attack cycles leave VWAP frozen at the historical baseline, keeping mirrorTick and
the floor conservatively anchored far from the inflated current price.
Also updated onchain/AGENTS.md to document the corrected recording direction.
Regression test (VWAPFloorProtection.t.sol):
- test_vwapNotInflatedByBuyOnlyAttack: asserts getVWAP() stays at bootstrap after N buy cycles.
- test_floorConservativeAfterBuyOnlyAttack: asserts floor center is far below inflated tick.
- test_vwapBootstrapsOnFirstFeeEvent: confirms bootstrap path unchanged.
- test_recenterSucceedsOnSellDirectionWithoutReverts: confirms sell-direction recenters work.
All 187 tests pass.

- Add AttackRunner.s.sol: structured forge script that reads attack ops from a
JSONL file (ATTACK_FILE env), executes them against the local Anvil deployment,
and emits full state snapshots (tick, positions, VWAP, optimizer output,
adversary balances) as JSON lines after every recenter and at start/end.
- Add 5 canonical attack files in onchain/script/backtesting/attacks/:
* il-crystallization-15.jsonl — 15 buy-recenter cycles + sell (extraction)
* il-crystallization-80.jsonl — 80 buy-recenter cycles + sell (extraction)
* fee-drain-oscillation.jsonl — buy-recenter-sell-recenter oscillation
* round-trip-safe.jsonl — 20 full round-trips (regression: safe)
* staking-safe.jsonl — staking manipulation (regression: safe)
- Add scripts/harb-evaluator/export-attacks.py: parses red-team-stream.jsonl
for tool_use Bash blocks containing cast send commands and converts them to
AttackRunner-compatible JSONL (buy/sell/recenter/stake/unstake/mint_lp/burn_lp).
- Update scripts/harb-evaluator/red-team.sh: after each agent run, automatically
exports the attack sequence via export-attacks.py and replays it with
AttackRunner to capture structured snapshots in tmp/red-team-snapshots.jsonl.

When feeDestination == address(this), _scrapePositions() now skips the
fee safeTransfer calls so collected WETH/KRK stays in the LM balance
and is redeployed as liquidity on the next _setPositions() call.
Also fixes _getOutstandingSupply(): kraiken.outstandingSupply() already
subtracts balanceOf(liquidityManager), so when feeDestination IS the LM
the old code double-subtracted LM-held KRK, causing an arithmetic
underflow once positions were scraped. The subtraction is now skipped
for the self-referencing case.
VWAP recording is refactored to a single unconditional block so it fires
regardless of fee destination.
New test testSelfFeeDestination_FeesAccrueAsLiquidity() demonstrates
that a two-recenter cycle with self-feeDestination completes without
underflow and without leaking WETH to any external address.

Add an explanatory comment to uniswapV3SwapCallback clarifying that
address(this) is pre-funded by _replaySwap before pool.swap() is
called, so no inline mint is required (unlike uniswapV3MintCallback).

- Fix fee attribution: distribute fees only to positions whose tick range
contains the active tick at close time (in-range weight), not by raw
liquidity. FLOOR is priced far below current tick and rarely earns fees;
the old approach would over-credit it and corrupt capital-efficiency and
net-P&L numbers. Fallback to raw-liquidity weighting with a WARN log
when no position is in range.
- Warn on first-close skip: when _closePosition finds no open record
(first recenter, before any tracking), log [TRACKER][WARN] instead of
silently returning so the gap is visible in reports.
- Add tick range assertion: require() that the incoming close snapshot
tick range matches the stored open record — a mismatch would mean IL
is computed across different ranges (apples vs oranges).
- Fix finalBlock accuracy: logSummary now calls
tracker.logFinalSummary(tracker.lastNotifiedBlock()) instead of
lastRecenterBlock, so the summary reflects the actual last replay block
rather than potentially hundreds of blocks early.
- Initialize lastRecenterBlock = block.number in StrategyExecutor
constructor to defer the first recenter attempt by recenterInterval
blocks and document the invariant.
- Extract shared FormatLib: _str(uint256) and _istr(int256) were
copy-pasted in both PositionTracker and StrategyExecutor. Extracted to
FormatLib.sol internal library; both contracts now use `using FormatLib`.
Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
- Add PositionTracker.sol: tracks position lifecycle (open/close per
recenter), records tick ranges, liquidity, entry/exit blocks/timestamps,
token amounts (via LiquidityAmounts math), fees (proportional to
liquidity share), IL (LP exit value − HODL value at exit price), and
net P&L per position. Aggregates total fees, cumulative IL, net P&L,
rebalance count, Anchor time-in-range, and capital efficiency accumulators.
Logs with [TRACKER][TYPE] prefix; emits cumulative P&L every 500 blocks.
- Modify StrategyExecutor.sol: add IUniswapV3Pool + token0isWeth to
constructor (creates PositionTracker internally), call
tracker.notifyBlock() on every block for time-in-range, and call
tracker.recordRecenter() on each successful recenter. logSummary()
now delegates to tracker.logFinalSummary().
- Modify BacktestRunner.s.sol: pass sp.pool and token0isWeth to
StrategyExecutor constructor; log tracker address.
- forge fmt: reformat all backtesting scripts and affected src/test files
to project style (number_underscore=thousands, multiline_func_header=all).

- Add BacktestKraiken.sol: extends MockToken with Kraiken-compatible interface
(dual mint overloads — public mint(address,uint256) for EventReplayer and
restricted mint(uint256) for LiquidityManager; peripheryContracts() stubs
staking pool as address(0))
- Add KrAIkenDeployer.sol: library deploying OptimizerV3Push3 + LiquidityManager
on the shadow pool, wiring BacktestKraiken permissions, setting fee destination,
and funding LM with configurable initial mock-WETH capital (default 10 ETH)
- Add StrategyExecutor.sol: time-based recenter trigger (configurable block
interval, default 100 blocks); logs block, pre/post positions (Floor/Anchor/
Discovery tick ranges + liquidity), fees collected, and revert reason on skip;
negligible-impact assumption documented as TODO(#319)
- Modify EventReplayer.sol: add overloaded replay() accepting an optional
StrategyExecutor hook; maybeRecenter() called after each block advancement
without halting replay on failure
- Modify BacktestRunner.s.sol: replace tokenA/B with MockWETH + BacktestKraiken,
integrate KrAIkenDeployer + StrategyExecutor into broadcast block; configurable
via RECENTER_INTERVAL and INITIAL_CAPITAL_WETH env vars; executor.logSummary()
printed after replay

- Guard final drift sample with `idx % LOG_INTERVAL != 0` to prevent
double-counting stats when totalReplayed is an exact multiple of
LOG_INTERVAL (the loop's _logCheckpoint already fired for that state)
- Hoist pool.slot0() before the guard and pass finalSqrtPrice/finalTick
to _logSummary(), eliminating the redundant slot0 read inside it
Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
- Cache pool.tickSpacing() as immutable in EventReplayer constructor
to avoid a repeated external call per _replayMint() invocation
- Rename driftCount → driftCheckpoints for consistency with log label
- Add sqrtDriftBps to the per-checkpoint progress log line, using the
now-live lastExpectedSqrtPrice field (previously written but never read)
- Guard _replaySwap(): skip and count events where amountSpecified ≤ 0,
which would silently flip exact-input into exact-output mode
- Add a final drift sample after the while-loop for trailing events not
covered by the last LOG_INTERVAL checkpoint
- Move EventReplayer construction outside the broadcast block in
BacktestRunner (it uses vm.* cheat codes incompatible with real RPC)
- Change second vm.closeFile() from try/catch to a direct call so errors
surface rather than being silently swallowed

- Replace hardcoded Infura API key with INFURA_API_KEY env var; fail fast
with a helpful message if unset and no --rpc-url is given
- Add onchain/script/backtesting/.gitignore (cache/) instead of relying on
the opaque root pattern; remove force-tracked cache/.gitkeep (mkdirSync
creates the directory at runtime)
- Document resume constraint: reliable only when both --start-block and
--end-block are explicit, or --output is set
- Fix batch-number display: derive batchNum inside the loop from the actual
`from` block so it stays correct when resumeFromBlock isn't BATCH_SIZE-aligned
- Guard log.logIndex === null consistently with blockNumber/transactionHash
- console.warn on decode errors instead of silently discarding them

Add onchain/script/backtesting/fetch-events.ts — a tsx script that:
- Fetches Swap/Mint/Burn events from a Uniswap V3 pool via Infura (Base mainnet)
- Batches eth_getLogs in 2 000-block chunks with 100 ms inter-batch delay
- Decodes each log with viem and writes one JSON Line per event
- Supports resume: reads last block from existing cache file on re-run
- Retries with exponential back-off on 429 / rate-limit errors
- Prints per-batch progress: "Fetching blocks X-Y... N events (B/T batches)"
Also adds package.json, tsconfig.json, and cache/.gitkeep.

OptimizerV3Push3 is an equivalence-proof contract with only isBullMarket().
It cannot serve as an ERC1967Proxy implementation because it has no initialize()
or getLiquidityParams(). The CI bootstrap was failing because the proxy
deployment reverted when calling initialize() on the Push3 implementation.
Switch deploy scripts to Optimizer.sol (the base UUPS contract) which has the
full interface required by ERC1967Proxy and LiquidityManager.

Add 11 new targeted tests in Stake.t.sol to cover all reachable
uncovered branches and the untested permitAndSnatch() function:
- testRevert_TaxRateOutOfBounds_InSnatch: taxRate >= TAX_RATES.length in snatch()
- testRevert_PositionNotFound_NonLastInLoop: PositionNotFound inside the multi-position loop
- testRevert_TaxTooLow_NonLastInLoop: TaxTooLow inside the multi-position loop
- testSnatch_ExitLastPosition: _exitPosition() path for last snatched position
- testRevert_ExceededAvailableStake: no available stake, no positions provided
- testRevert_TooMuchSnatch_AvailableExceedsNeed: post-exit excess stake check
- testRevert_PositionNotFound_InChangeTax: changeTax() on non-existent position
- testRevert_TaxTooLow_InChangeTax: changeTax() with same/lower tax rate
- testRevert_NoPermission_InExitPosition: exitPosition() by non-owner
- testRevert_PositionNotFound_InPayTax: payTax() on non-existent position
- testPermitAndSnatch: EIP-712 permit + snatch in one transaction
Coverage achieved:
Lines: 99.33% (148/149)
Statements: 99.40% (167/168)
Branches: 93.55% (29/31) — 2 unreachable dead-code branches remain
Functions: 100.00% (15/15)
The 2 uncovered branches are dead code: the require() failure in
_shrinkPosition (caller always guards sharesToTake < pos.share) and
the PositionNotFound guard in exitPosition() (unreachable because
owner and creationTime are always set/cleared together, so
pos.owner==msg.sender implies pos.creationTime!=0 for any live caller).

- Add `require(averageTaxRate <= 1e18, "Invalid tax rate")` to match
the existing `percentageStaked` guard and prevent silent acceptance
