Make burn_lp ops fork-block-independent by using a 1-based positionIndex
(resolved at runtime from prior mint_lp ops) instead of hardcoded NFT
tokenIds. Mirrors the existing pattern used by unstake/_stakedPositionIds.
Also log a warning when burn_lp encounters zero liquidity instead of
silently becoming a no-op.

Make V3_FACTORY injectable via vm.envOr("V3_FACTORY", DEFAULT_V3_FACTORY),
preserving the Base mainnet address as the default for existing fork runs.

Add inline Basescan URL comment identifying V3_FACTORY as the Uniswap V3
Factory on Base mainnet, consistent with the existing comment style used
for NPM_ADDR in both files.

Replace 0x27F971cb582BF9E50F397e4d29a5C7A34f11faA2 (Base Sepolia
NonfungiblePositionManager) with the correct Base mainnet address
0x03a520B32c04bf3beef7BEb72E919cF822Ed34F3 in all four files that
referenced it, and add an inline comment citing the chain and source.

Add `buy_recenter_loop` batch op to AttackRunner — executes N×(buy→recenter)
cycles in a single Solidity loop, emitting snapshots after each recenter.
Rewrite il-crystallization-80.jsonl from 153 individual JSONL steps to 2 lines
using the new op with count=80, matching the intended attack name. Also corrects
the cycle count from 76 (previous file) to the intended 80.

After a buy→sell round-trip the net price movement is near zero, so
recenter() reverts with "amplitude not reached" and aborts the whole
AttackRunner script.
Wrap the recenter() call in a try/catch so amplitude failures are
caught and logged as a skipped step rather than propagating as a fatal
revert. When recenter is skipped, no state snapshot is emitted and the
attack sequence continues — matching the intended semantics: round-trip
trading should not cause the fitness scorer to crash.

Stake.nextPositionId starts at 654_321, so attack files cannot use literal
on-chain IDs (e.g. positionId=1 always reverts with PositionNotFound).
Fix AttackRunner to treat the JSONL positionId field as a 1-based index into
the list of positions created by stake ops during the current run:
- Add IStake.snatch returns (uint256) to the interface so the returned ID is
captured.
- Track returned IDs in _stakedPositionIds[] (inserted in creation order).
- _executeUnstake resolves positionId to _stakedPositionIds[positionId-1]
before calling exitPosition, matching the natural "unstake position 1"
semantics in the attack DSL.
KRK approval for Stake was already present in _setup(); no other changes needed.

- **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.

- 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.
