StarForth_Physics_Diagnostic_Words.thy (physics_diagnostic_words.c): 3 of 4 words are pure-printf identity transitions; PHYSICS-BURN's guard modelled, its arbitrary dynamically-selected func-pointer execution loop is a new class of gap (not reducible to any prior one). StarForth_Physics_Benchmark_Words.thy (physics_benchmark_words.c): hot-words cache is a whole unmodelled subsystem. PHYSICS-RESET-STATS's pipeline_metrics half (3 real vm_state fields) modelled; everything else in the file deferred. StarForth_Physics_Pipelining_Diagnostic_Words.thy (physics_pipelining_diagnostic_words.c): root-cause finding -- `word_transition_metrics` has been a declared record type in StarForth_Base.thy since early in the sweep but was never wired into `dict_entry` as a field, so every word in this file touches state with zero abstract representation. Three no-arg words modelled as identity (with an explicit caveat that this reflects the model's blind spot, not a no-op claim about the C); the three lookup words get only their simplest empty-stack underflow case. Suite now 43 theories, green.
