- **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.
