    "32 serial fresh workers: core/actual observation consumer x 8/32 steps x float32/64 x eager/compiled x two repetitions; order reversed in repetition two. One CPU affinity; OMP/OpenBLAS/Inductor compile threads one. Empty isolated compiler caches, cache disabled for native records. 25 warm forward and value+gradient calls per worker; independent discrete RK4 value/gradient gates for two parameter sets.",
    "Both modes in the primary 32-worker protocol import compiler diagnostic modules. This inflates instrumented eager import/RSS compared with ordinary eager use; do not present that baseline as plain eager memory. Eight additional plain-eager controls omit unused diagnostic imports and retain all other numerical consumer code. Controls are a separate memory/import probe with one worker per shape/precision/consumer, not pooled with the primary timing ratios.",
    "Cold forward and cold backward are separate; warm value+gradient includes its forward. RSS is the main Python process high-water mark, includes imports/compiler state, and excludes child compiler processes. It is not a hard memory cap or device memory.",
    "Two source snapshots during collection differ only in lint comments; their complete executable ASTs are identical and all exact snapshots/hashes are retained. Other recorded numerical/fixture sources have one exact hash across every worker.",
    "Only two timed worker replicates per condition, one host and bounded synthetic consumers. There are no timing CI thresholds, universal speedup, accuracy, GPU, SBI training or application-adoption claims. The 8-step core float32 warm forward regresses; retain that result.",
    "Compiler counters are version-specific diagnostics: all compiled workers have native Inductor kernels and no graph-break counter events; source selects fullgraph=True, backend=inductor. Strict disabled/graph-break tests are qualified separately."
