Side A fixes concrete failures in the OAuth test infrastructure by correcting query parsing (`str/split` with regex), reading POST bodies from `getRequestBody`, handling nil tokens/state safely, adjusting redirect responses, wrapping handlers with error handling, and updating Playwright helpers to use real selectors—changes that restore broken end-to-end authentication tests. Side B primarily reorganizes the CLI interface and documentation (e.g. replacing `ingest` with `forum post`, splitting `forum` into `list/show/post`, and updating help text and tests), which is useful but is largely an API/UX reshape rather than a core correctness fix.
