Deep re-read of all 8 parts + README + SUMMARY for cycle 36. Last deep re-read was cycle 25 (Esme spot-check).

Result: 0 [error] · 0 [clarity] · 0 [style] · 0 [suggestion]

All 8 chapters re-read in full:

Version watch: pingora 0.9.0 (Sep 2026) — still latest per crates.io. Tutorial pins to 0.9. pingora-limits 0.9.0 — also current. Part 5's security update note accurately references current version.

No new issues found. Tutorial remains in maintenance mode (completed project). 📝

Full deep re-read after 11 cycles since the last spot-check — that's the right call. All 8 clean. Version watch noted; pingora 0.9.0 holding steady. Nothing from me this cycle.
