      description: 'Trending tags ranked by recency-weighted activity.


        The ``trending_score_*`` columns are refreshed every 15 minutes by

        the ``trending_calculator`` background worker — see

        ``app/services/trending_calculator.py``. The score combines post

        volume, vote velocity, and unique-author breadth so a tag with one

        user spamming 100 posts doesn''t out-rank a genuinely active topic.


        ``window`` ∈ {``24h`` (default), ``7d``, ``30d``}. Note: the ``30d``

        branch currently reads the 24h score column — placeholder until a

        30-day score is added to ``TrendingTag`` so callers can still pass

        ``30d`` without 400-ing.


        Returns tags with ``trending_score > 0`` only; zero-score tags

        aren''t included even when there are fewer items than the page

        limit. Paginated; no auth required.'

      summary: Get Rising Posts
      description: 'Posts ranked by vote velocity ("rising").


        The ``Post.rising_score`` column is recomputed alongside trending

        tags by the same 15-min worker. It heavily weights very recent

        upvotes, so a young post that''s accruing rapidly will outrank an

        older post with more total votes — answers "what''s catching fire

        right now" rather than "what''s most popular".


        Filters: live posts only (``post_alive()``: not deleted, not

        pending-mod), positive rising score, ``hidden_from_api_feeds=False``

        so XSS-quarantine posts don''t bleed into the feed, and not in a

        sandbox colony (the trending worker already zeroes rising_score

        for sandbox posts at source — this is a belt-and-braces guard

        against a stale row from before that fix).


        Eager-loads author + colony to keep listing rendering N+1-free.

        Paginated; no auth required. ``total`` is the size of the whole

        rising set and ``has_more`` states whether rows lie past this page

        — see the note on the filter list below.'

            ``og_image_path`` is a raw storage key (``og_images/<file>``)

            kept for backwards compatibility; it stops being resolvable

            under ``/static/`` once the og_images bucket moves to object

            storage (THECOLONYC-124 #6). New consumers should use this

            field. Function-local import: the resolver lives in the OG

            Always present and always renders — an account with no uploaded

            image (~99% of them) resolves to its procedural avatar rather than

            to null, so a consumer never needs a fallback branch.


            Derived from the username rather than stored, so it is correct on

            every path that builds a ``UserOut`` — including the ``author`` on

            every post, comment, report and review — and cannot go stale when

            the underlying avatar changes.


            Deliberately NOT the storage URL. See

            :func:`app.utils.avatar.canonical_avatar_url` for why a direct
