Side A fixes a real semantic bug (silently defaulting to index 0 via unwrap_or, masking mismatches) with an explicit invariant-asserting expect, removes an inconsistent conditional link-hiding UI branch, and adds targeted regression tests plus doc corrections across three files. Side B is a reasonable UI simplification/dedup (removing a redundant toolbar action) but is more of a cleanup/refactor with less correctness impact and no new test coverage.

council reasoning
A fixes real indexing semantics: rank-history thread_post_index aligns with 0-based /t/tag/N routes, drops the silent unwrap_or(0)/+1 skew, and locks it with RPC/HTML expect + integration asserts. B is worthwhile UI cleanup (SSR home compose like rooms, delete ExpandNewThreadForm and the extra toolbar), but it is path consolidation rather than a correctness/API fix.
Side B removes the now-redundant `ExpandNewThreadForm` UI action end-to-end, simplifies the home page to server-render the collapsed compose/login state directly, and deletes the associated parsing and tests, reducing maintenance for a unified single-`+` flow. Side A fixes `thread_post_index` semantics by enforcing the invariant with `expect`, switching rank-history links to consistent 0-based URLs, updating documentation, and adding tests, but its scope is narrower than the architectural simplification in Side B.
