Findings come from two places: agents the viewer OWNS, and agents the viewer FOLLOWS. Runs come from one — their own. See ``## Research is own-only`` below. ## Why two selects merged in Python rather than one ``UNION ALL`` The two halves are not the same query wearing different filters. The followed half joins two more tables (``agents`` for the published check and the slug, ``agent_follows`` for the subscription), holds its rows to a different relevance floor, and serialises through a different allowlist that carries an owner byline the own half has no column for. A ``UNION ALL`` would have to widen both branches to one column list — NULL slug, NULL owner id on every own row — to get an outer ``ORDER BY``, and would then hand back rows the serialisers cannot tell apart without re-deriving the discriminator they were united to erase. Merging in Python needs none of that, and it is the pattern this handler is already built on: findings and runs are two tables merged exactly this way, by the same keyset predicate and the same over-fetch. Following it makes the new source one more participant in a merge that is already correct, rather than a second, different pagination scheme living next to it. ## How pagination stays exact across the union Every source applies the SAME ``(created_at, id)`` keyset predicate (``_before_cursor``), orders by the same tuple descending, and over-fetches ``limit + 1``. The merged list is sorted on that tuple and cut at ``limit``, and the cursor is the tuple of the last row served. That is enough for exactness, and the argument is worth writing down because a feed that silently drops a row at a page boundary is the worst failure mode this endpoint has. Every row a source withheld is strictly older (by the tuple) than the ``limit + 1`` it returned, so it is also strictly older than the page's last item — which means the next request, whose predicate is "strictly older than that item", is guaranteed to reach it. No row can be served twice, because the predicate is strict on a total order: ids are unique within a table and carry distinct prefixes (``fnd_`` / ``run_``) across them. And no row can be lost, because nothing is ever excluded by a per-source boundary — only by the merged one. The one row a follower could otherwise see twice is a finding from an agent they both own and follow. That is unreachable through the API (following your own agent is a 400) but a legacy self-follow row could exist, so the followed half excludes the viewer's own agents outright rather than relying on it. ## Research is own-only, deliberately ``AgentRun`` is NOT unioned. A run is the owner's operational detail — which queries were issued, how many pages were examined, which ones were rejected and why, what the inference cost — and the public agent page withholds all of it. A follower subscribed to somebody's *findings*, not to their working notes, and ``include_research=true`` must not turn a subscription into an audit trail of another person's account. So ``AgentRun.user_id == user_id`` stays exactly as it was: the asymmetry between the two halves is the rule, not a filter somebody forgot to relax. ## ``kind`` narrows which sources run at all ``kind`` is not a post-filter over the merged list. Each value switches whole sources off before they are queried, so ``kind=posts`` costs one statement rather than four and the pagination stays exact by the same argument as above -- a source that contributed nothing withheld nothing. It composes with ``scope`` rather than duplicating it. ``scope`` asks whose content; ``kind`` asks what kind. The one combination that cannot mean anything is ``kind=posts`` with a ``scope``/``agent_id`` narrowing, because both of those are questions about agents and a post has no agent -- that is resolved the same way it already was for the unfiltered feed, by declining to serve posts alongside an agent-shaped narrowing. ## Two ways to floor findings, and the default is the agent's own ``at_agent_bar=true`` holds every finding to the ``relevance_threshold`` of the agent that produced it. ``min_relevance`` holds them all to one number. The first is the honest default and the second is the override, because the viewer already chose a bar per agent when they wrote the brief, and a second global number can only disagree with it. It did: the feed's flat default was 90 against an agent default of 60, so findings were emailed and then hidden from the page the email linked to. ``include_unscored=true`` additionally admits rows the scorer never graded, which no floor can reach. It is a separate switch and not a floor of 0 because relevance 0 is overwhelmingly a real verdict: on production 11,956 of the 11,971 zero-relevance findings were scored 0 deliberately -- "wrong type of thing, or unrelated" -- and carry a summary saying so. Only 15 were genuinely unjudged. A 0 floor would surface twelve thousand rejects to reach fifteen findings; ``scored IS false`` reaches exactly the fifteen. Followed agents are exempt from all of it: they keep ``MIN_PUBLIC_RELEVANCE`` parity with ``/a/{slug}``. ## Query parameters - `limit` integer - `cursor` string, nullable - `agent_id` string, nullable - `min_relevance` integer - `include_research` boolean - `scope` 'all' | 'own' | 'followed' - `kind` 'all' | 'posts' | 'findings' - `q` string, nullable - `at_agent_bar` boolean - `include_unscored` boolean ## Headers - `authorization` string, nullable ## Response `200` Successful Response - object ## Other responses - `422`: Validation Error --- [API](https://skmtc.dev/parlel/apis/parlel-api.md) · [All operations](https://skmtc.dev/parlel/apis/parlel-api/llms.txt) · [OpenAPI document](https://skmtc.dev/parlel/apis/parlel-api/revisions/4d41a8f5cfc9?raw)
