Side B fixes a real off-by-one/index-base bug (1-indexed vs 0-indexed thread_post_index) across server rpc, HTML rendering, and types, and backs it with new integration test assertions verifying correctness, giving lasting correctness value. Side A also fixes real bugs (regex split, request body vs input stream, missing try/catch, null-state handling) improving test infra robustness, which is valuable but more localized to test harness code rather than production logic.

council reasoning
A fixes multiple concrete mock-server bugs (wrong HttpExchange body stream, 302 content-length, fragile query split, null token/state) that had broken real Clojure E2E/Playwright OAuth login, plus makes alias/history reads use reliable selectors. B only tightens thread_post_index to mandatory 0-based indexing with expect and always-on links—a valid consistency fix, but narrower and less unblocking than restoring auth E2E.
Side A fixes multiple concrete failures in the OAuth test infrastructure: it corrects query parsing (`str/split` with regex), reads POST bodies from `getRequestBody`, avoids null crashes when parsing bearer tokens and missing state, fixes redirect response handling, wraps handlers with error reporting, and updates Playwright helpers to use selectors reliably. Side B mainly changes rank-history indexing semantics by replacing a fallback with `expect`, updating documentation/tests, and always rendering a link, which is a narrower behavioral cleanup with less broad impact than restoring broken end-to-end authentication flows.

[075d4d37] Fix OAuth test mocks so Clojure E2E auth flows work again. HttpServer handlers were crashing on query parsing and token POSTs, which broke Playwright login; also read alias/history via real CSS selectors. Co-authored-by: Cursor <cursoragent@cursor.com>
