nx_probe_multierr_live.nx -- LIVE WITNESS for MULTI-ERROR RECOVERY (2026-08-05). One broken build must report EVERY semantic error it can see, not just the first: rustc/Elm report all, and a compiler that stops at error 1 charges the author one full rebuild per mistake. REPRO: change me_one(1) to me_onex(1) AND me_two(2) to me_twox(2) and /api/build -> BOTH errors must appear in full 5W+H voice (error at line N: I do not know the name ..., caret, why the build stopped, closest defined name + quoted declaration, fix), then: error: the build found 2 problem(s), listed above, and wrote no program. Kept VALID in-tree (compiler-root probe convention). license_tier: ORIGINAL expect_exit: 0
