Share tagged readiness observations, retain partial provider facts, authenticate bridge identity, bound diagnostics, and preserve cancellation and lost-session reasons. Fail closed for unparsed MIPS ABI attributes and macOS saved Hopper databases without a script-capable bridge route.
Reviewed fixes: #2010, #2108, #2513, #2695, #2731, #2771, #2828, #2867, #2868, #2870, #2880, #2919, #2945, #2961, #2981, #2998, #3000, #3002.
Validation: 285 focused source/boundary tests passed. Real Ghidra, IDA, Linux Hopper, and Windows provider runs were not repeated.
BREAKING CHANGE: MIPS targets with unresolved GNU ABI attributes and saved Hopper databases on macOS are refused rather than advertised as supported.
