Add `url` field to profile activity items so post cards link to `/posts/{slug}` and comment cards link to the parent post with a `#comment-{uid}` anchor, matching notification click behavior. Include the shared `_card_link.html` overlay in the template, fix XP bar rendering for missing `xp` key, and add API + e2e tests verifying the link structure and navigation.
Implement a new `avatar_seed` column on the users table that overrides the username-based seed for Multiavatar generation. Introduce a null-safe `avatar_seed(user)` choke point in `avatar.py` that resolves `user.get("avatar_seed") or user.get("username")`, registered as a Jinja global so every render site (`_avatar_link.html`, `avatar_url(...)` calls, SEO `og_image`, issues ad-hoc dicts, devRant payload/PNG) propagates a regenerated seed. Add `POST /profile/{username}/regenerate-avatar` endpoint (owner-or-admin only) that writes a fresh `generate_uid()` to `avatar_seed`, invalidates the target's user cache, and audits `profile.avatar.regenerate`. The previous seed is overwritten and never stored, making regeneration irreversible. Document the feature in `AGENTS.md` and `README.md`, add the API endpoint to `docs_api.py`, and include the `regenerate_avatar` Devii tool in `CONFIRM_REQUIRED`.
Implement a Farmville-style cooperative idle game mounted at `/game` with member-only play and public farm viewing. The data layer is pure and timestamp-driven with no background tick: plot states are derived from `ready_at` vs current time, never stored. Key features include plantable software projects (shell script through kernel) that build over real time, harvest for coins and XP, CI tier upgrades for faster builds, plot purchasing with doubling cost, watering mechanics for friends' builds, daily quests, and prestige system. All game endpoints negotiate HTML or JSON and return full farm state for single-request client refresh. Pub/sub notifications broadcast farm updates on `public.game.farm.{username}` topics. Database schema adds `game_farms`, `game_plots`, and `game_quests` tables with appropriate indexes.
