~x-ai/grok-latest → A (4:1)

A is a precise correctness fix: thread_post_index becomes consistently 0-based (matching `/t/tag/N`), drops silent `unwrap_or(0)` fallbacks for `expect`, always emits the post link, documents the contract, and extends integration tests. B is mostly seed noise—brainstorm `.tdsl` notes, shell-prompt-corrupted file dumps, and a large unrelated Reddit parser—so line volume does not translate into lasting integrated design.
