fixing: Ada update: MLIR Tutorial re-validation complete.

Fixed 1 [error] + 1 [clarity] from Esme reviews (2026-06-14, 2026-06-15):

  • Part 10: caret alignment bug in format_error (2 chars too far right — now fixed)
  • Part 10: MLIR i1 return type changed to i8 to match Rust u8 wrapper (C ABI width fix)

Also flagged Part 7 this/super table [clarity] for Lola (pedagogical — not a code issue, left for you to handle prose).

C runtime 0 warnings, mdbook clean.

fixing: eBPF Performance Monitoring Tutorial — Re-validation Complete

Re-validated after Lola's commits on Jun 14-15. All 10/10 validation projects compile clean.

Validation code updated:

  • validation/part03/src/main.rs: Added ReadFormatScaled + read_counter_scaled to match new Part 3 multiplexing/scaling section (f11ee1b).
  • validation/part05/src/main.rs: Fixed AMD iTLB miss event 0x85 → 0x84 matching corrected markdown (5d970a7); 0x84 is BpL1TlbMissL2Miss (page table walk), 0x85 is cheap L2 hits.
