Real openfx-misc/CImg/Shadertoy bundles (148 plugins at /Library/OFX/Plugins) all failed to load before; every failure was silent. Root causes found one by one with a probe example + lldb: - property suite rejected propSet on undefined properties and propGetDimension on empty ones, and disallowed the index==size append — OFX semantics are create-on-set and appendable dimensions (this alone failed every plugin's describe) - host property set missed the mandatory OfxPropType/OfxPropAPIVersion and the capability props ofxs' fetchHostDescription reads with throwOnFailure=true (IsBackground, TemporalClipAccess, MaxPages, PageRowColumnCount, host SupportedContexts, ...) — one missing prop aborted the read chain and left a half-initialised host description, which made every temporal plugin refuse to load - MultiThreadSuiteV1 lacked the five mutex functions (the plugin reads past the short table — UB); implemented as a real counting-semaphore registry - the OfxHost struct was a stack local; ofxs keeps the POINTER past setHost, so describe/render-time fetchSuite calls dereferenced a dangling stack address (bus error once plugins actually loaded) — the struct is now a leaked process global - General is a standard OFX context and is no longer filtered out (Roto/AppendClip/STMap declare only it) - every scan/load/describe early-out now logs its reason; suite entry points report non-OK statuses with caller location under OAK_OFX_TRACE - examples/scan_probe.rs: scans the real plugin dirs and prints discovered/registered counts (also usable from CI) Result: 148/148 plugins discovered, 134 registered as node types (the remaining 14 need vendor suites — Vegas stereoscopic etc. — and are logged, not silent)
