CM-4 adjudicated: timing not normative — retire the exam kit into #43 - #46
Merged
Conversation
…xam kit into #43 sync-streams.wast:145 pins a scheduler policy (wasmtime's deferred entry decision), not semantics: an upstream test defect, not a reference bug. Both sketched amendments are withdrawn; definitions.py, CanonicalABI.md, and test_callback_interleaving need no change. The bounded §1 exception shrinks back to CM-3; the CM-4 lesson becomes its guard (corpus assertions must be schedule-independent to count as semantics). Runtime unchanged: hold gate = conformance, drain-to-quiescence = non-normative policy (#45). exams/wasmtime-exclusivity/ is removed — distilled onto issue #43, archived at 4f3351f:exams/wasmtime-exclusivity/.

Closes out CM-4 per the operator adjudication (2026-08-10): entry-status timing is not normative —
sync-streams.wast:145overfits wasmtime's deferred-entry scheduler policy (an upstream test defect; pristine definitions.py answers STARTING under every schedule it can produce). Both previously sketched amendments are withdrawn.exams/wasmtime-exclusivity/removed (−1,100 lines); the finding + filing kit is distilled on CM-4: sync-streams.wast:145 overfits wasmtime's scheduler — upstream test-defect filing kit #43, full artifacts archived at4f3351f:exams/wasmtime-exclusivity/.No behavior change. Gates:
