Three defensive layers so every Push3 program runs without reverting:
Layer A (transpiler/index.ts): assign bear defaults (CI=0, AS=0.3e18,
AW=100, DD=0.3e18) to all four outputs at the top of calculateParams.
Any output the evolved program does not overwrite keeps the safe default.
Layer B (transpiler/transpiler.ts): graceful stack underflow — dpop/bpop
return '0'/'false' instead of throwing, and the final output-pop falls
back to bear-default literals when fewer than 4 values remain on the
stack. Wrong output count no longer aborts transpilation.
Layer C (transpiler/transpiler.ts + index.ts): wrap the entire function
body in `unchecked {}` so integer overflow wraps (matching Push3), and
emit `(b == 0 ? 0 : a / b)` for every DYADIC./ (div-by-zero → 0,
matching Push3 no-op semantics).
Layer 2 (Optimizer.sol getLiquidityParams): clamp the three fraction
outputs (capitalInefficiency, anchorShare, discoveryDepth) to [0, 1e18]
after abi.decode so a buggy evolved program cannot produce out-of-range
values even if it runs without reverting.
Regenerated OptimizerV3Push3.sol with the updated transpiler; all 193
tests pass (34 Optimizer/OptimizerV3Push3 tests explicitly).

- 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 `require(averageTaxRate <= 1e18, "Invalid tax rate")` to match
the existing `percentageStaked` guard and prevent silent acceptance
of out-of-range values.
- Expand contract-level NatSpec with a @dev note clarifying this is an
equivalence proof only: it intentionally exposes `isBullMarket` alone
and is not a deployable upgrade (full optimizer interface missing).
All 15 Foundry tests pass (15 unit + fuzz).
