Deep bug review

[nficano]

Systematic correctness pass — not just "do tests pass," but "is this actually right."

Scope

• Walk every public entrypoint and trace error paths
• Edge cases: empty inputs, max sizes, unicode, concurrent access where relevant
• Resource handling: file handles, sockets, async cancellation
• Off-by-one, overflow, and rounding spots
• Re-validate any behavior that changed in Refactor pass 1 #1/Refactor pass 2 — verification sweep #2
• File follow-up issues for anything found; fix the small stuff in-place
