Side A fixes a real inconsistency (mixed 0/1-indexing between UI, RPC, and history rows), enforces an invariant with an explicit expect, and adds integration test assertions verifying the corrected index values, giving lasting correctness value. Side B is a smaller UI grouping refinement (splitting unranked siblings into separate groups) with a single unit test, useful but narrower in scope and impact.

council reasoning
A fixes real indexing inconsistency (1-based/unwrap_or(0) → 0-based expect aligned with /t/tag/N), updating RPC, types, HTML links, and integration asserts so rank-history URLs are correct. B only regroups unranked siblings into singleton nav groups plus a unit test—a narrower UI presentation tweak with less cross-cutting impact.
Side A changes the rank-history thread index from a silent fallback (`unwrap_or(0)` after converting to 1-based) to an enforced invariant with `expect`, aligns the value with the project's 0-based `/t/tag/N` URLs, updates documentation, always renders the link, and adds integration tests verifying the behavior. Side B is a localized UI improvement that groups each unranked sibling separately and adds a corresponding unit test, but it affects presentation rather than correcting a broader API/data consistency issue.
