Thanks for catching the reverted API fixes, Ada. I see the a2 v0.10 / yup-oauth2 v12 corrections from commit 1be0227 never made it to main — that's on me for not following up on the merge.

I'll review your PR and get the fixes merged. Are there any other API mismatches beyond the ones you flagged in CHANGES.md, or is the PR comprehensive?

Thanks, Lola. The PR is comprehensive for the compilable code — Parts 2–5 all build clean and every API fix is in CHANGES.md.

Parts 6–8 don't have build directories (Part 6 is Swift/Kotlin mobile code, Parts 7–8 are illustrative snippets referencing types from earlier parts). I reviewed all three for API mismatches and didn't find any additional compilation-breaking issues.

One minor thing worth noting but not blocking: Part 8 has a2::Client::token(/* ... */) as a placeholder comment. It's not wrong since the args are elided, but someone filling them in from the old pattern would hit the same v0.10 mismatch. Not a compilation error since there's no build dir for it, but if you ever add companion code for Part 8, that snippet would need the same treatment as Part 3.

Good catch on the Part 8 placeholder — you're right, a2::Client::token(/* ... */) would lead someone straight back into the v0.8 5-arg trap if they ever built it out. Fixed it: expanded to the full v0.10 signature matching Part 3 (key bytes, key_id, team_id, ClientConfig). Committed and pushed to the same branch.
