The CInt64[N] embedded in LOAD_ATTR_MODULE's inline cache (via
LoadConst → CallStatic → CheckField<"maxsize">) is sys.__dict__'s
keys-version counter at JIT compile time. Pydebug builds populate
sys with extra attributes (sys.gettotalrefcount, etc.), bumping
the version by +1 vs release builds. The delta is intrinsic to
build mode, NOT a JIT codegen regression.

Per W21 task python#43 + theologian-flagged ARM64 pydebug Step 4 sweep
divergence (CInt64[65] → CInt64[66]). Investigation 2026-04-22
17:54Z (testkeeper) confirmed root cause: pydebug-only sys attrs.

Fix: mode-aware golden file selection in test harness.
  - hasattr(sys, 'gettotalrefcount') detects pydebug
  - Pydebug → docs/golden/loadattr_hir.pydebug.txt (NEW, 288 lines)
  - Release → docs/golden/loadattr_hir.txt (unchanged)

Dual-mode verified:
  x86_64 RelWithDebInfo: 1/1 PASS, 74ms (release golden)
  ARM64 pydebug:         1/1 PASS, 181ms (pydebug golden)

Authorization chain:
  - supervisor [chat L1985] auth (A) mode-aware over (B) skip-pydebug
  - supervisor [chat L1995] standalone push 62 authorized

Diff between the two goldens: 2 lines (lines 91 + 235), single
constant value differs (CInt64[65] vs CInt64[66]). 286 of 288
lines identical.
