Fr0zkaandClaude Opus 5 cda082fa10 docs(design): Sol reads the code -- three changes worth testing, one determinism hole
Round two of the owner's "build it every better way" question: Sol's round-one session was forked
read-only and given the repository, to say what could reasonably change and how each change would
prove its worth. Advice only; nothing was changed, built or run.

Sol's verdict: don't rebuild. The representation, mesher, clipmap and operator stack are already
close to its clean-slate design. Three things are worth testing, each with a cheap
instrumentation-only first step and explicit kill criteria:
- tile-wide, feature-major tunnel evaluation (inferred 8-18% of worker CPU);
- exact density reuse across adjacent gameplay tiles (theoretical ceiling ~23%);
- a canonical numeric contract for world-deciding maths (correctness, ~neutral on speed).

The orchestrator verified against the code and the UE 5.7 engine source:
- FMath::Sin/Cos resolve to the CRT sinf/cosf on Win64 (FMA3 variant chosen at runtime);
- per-sample lookup is ~5% exclusive, so round one's "the loop direction is the largest gap"
  overstated it;
- worker-thread parse-once flags, raw-memory CRC cache keys and a docs-vs-code contradiction on
  landing connectors are real.
Round one's note gets a pointer to the corrections.
