A is a purely mechanical cleanup that removes a leftover duplicate forum.rs to fix module-resolution ambiguity — necessary but trivial housekeeping with no design change. B finalizes a real architectural shift in URL canonicalization, replacing the ad-hoc per-domain rule engine (engine.rs with hardcoded reddit/youtube functions) with a more general graph/DFA-based resolver (graph.rs/parse.rs) plus updated docs, which is a more substantive and lasting improvement to core logic even though some test consolidation obscures full visibility of the new implementation.

council reasoning
B replaces the old composable ParsedUrl/engine normalizers and domain_key match arms with a graph-based canonicalization API (registry thin wrapper over graph/parse, docs and tests re-homed), which is lasting core ItemId design. A mostly deletes the leftover monolithic forum.rs and redistributes the same forum HTML into forum/* modules plus a small timeago import fix—necessary structure cleanup, but little new behavior or design.
Side A resolves a real module-structure issue by removing the duplicate `server/src/html/forum.rs`, adding `forum/mod.rs`, and making `forum/` the single module root while preserving behavior through extracted modules like `feed.rs`, `views.rs`, and `thread_morph.rs`. Side B replaces the URL canonicalization engine with a new graph-based architecture and updates the registry API, but the visible patch largely swaps implementations and removes in-file tests without showing the new core logic, making its lasting functional impact less directly evident from the diff.

[21b57b50] fix(html): drop duplicate forum.rs; use forum/ as sole module root Removes the leftover monolithic file so mod forum resolves to forum/mod.rs without ambiguity. Keeps feed, views, and other split modules as the source. Made-with: Cursor
