Side A fixes a real XSS vulnerability by sanitizing untrusted Reddit HTML before rendering, a small, precise, security-critical change with tests. Side B is a large refactor consolidating POST /post, /post/check, /post/redact into a single /ui RPC endpoint—useful cleanup but riskier, sprawling, and not addressing a correctness/security defect.

council reasoning
A adds a real, lasting XSS defense (ammonia whitelist + tests) for untrusted Reddit HTML embedded via PreEscaped, fixing a concrete security hole at the render sites. B is a worthwhile unification of /post* into the /ui RPC path and deletion of web_post.rs, but it is mostly moving and rewiring existing logic without new protective or functional substance.
Side A fixes a concrete security vulnerability by introducing Ammonia-based sanitization for untrusted Reddit `body_html` before `maud::PreEscaped` rendering, adds a reusable `entity_body_html` helper, and includes tests verifying scripts and event handlers are stripped while benign markup is preserved. Side B is primarily a large refactor that consolidates `/post*` flows into `/ui`, moves code, and changes routing and form submission patterns, but it mostly reorganizes existing behavior rather than adding comparable enduring functionality.

[bf118bdf] Sanitize Reddit entity body HTML before rendering. Use ammonia at render time so untrusted selftext_html cannot execute scripts in our origin. Co-authored-by: Cursor <cursoragent@cursor.com>
