Measured hazard counts for a Java->Nim port, with the correction that only 22 of 28 top-level classes ship source (6 do not: 5 in the gun package plus dMove/Scan), so a full port would need a decompiler while a shim would not care at all. Real traps: 193 float / 35 casts / 147 literals / 60 float[] in the movement closure (the danger histogram is float[171] -- porting 32-bit Java floats to Nim's default float64 diverges silently); ~68 non-final statics; and 4 Java single-& sites with side effects, which break under Nim's short-circuiting 'and'. Non-issues, correcting earlier assumptions: 0 sites of %-on-negative (angle normalisation is floor-based) and FastTrig has no lookup tables, it is 7 coefficient-exact polynomials. Movement scoping: 5007 LOC across 14 files, ~4.8-6.1k Nim LOC, 4-8 focused agent-days to first-compiles. It can be ported WITHOUT the gun (data flows movement->gun only), but the harness never routes HitByBullet into movement modules, so the danger bins would never train -- that plumbing is the real blocker, not the translation.
