From c132783ea0a1743892aa154bf597bf616f0fde04 Mon Sep 17 00:00:00 2001 From: Teknium <127238744+teknium1@users.noreply.github.com> Date: Thu, 23 Jul 2026 08:03:19 -0700 Subject: [PATCH] test(slack): regression coverage for thread image/file context visibility MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Covers cluster C1-images (#69185, #32315, #66136): - _slack_file_marker unit tests: typed markers per mimetype family, hostile-filename sanitization (newlines/brackets can't fake context structure). - _render_message_text appends markers; a caption-less image post no longer vanishes from thread context. - Cold-start hydrate integration: prior-message images surface as markers in channel_context; the thread root's image is downloaded, delivered as media_urls, and upgrades message_type to PHOTO. - Failure path: root-image download failure degrades to the marker, never blocks the turn. - Bounds: root delivery capped at _THREAD_ROOT_IMAGE_MAX; non-image root attachments stay marker-only (no download). - One-time delivery: active thread session skips the hydrate → no re-download/re-delivery on later turns. - Composition: the trigger's own event files still ride alongside a delivered root image; Slack Connect stubs resolve via files.info; the collector never issues its own conversations.replies call. - Delta refresh (#23918 path): images in new replies past the watermark surface as markers, with no root re-download. A/B: 14 of 15 tests fail with the adapter fix reverted, all pass with it applied. --- tests/gateway/test_slack.py | 429 ++++++++++++++++++++++++++++++++++++ 1 file changed, 429 insertions(+) diff --git a/tests/gateway/test_slack.py b/tests/gateway/test_slack.py index e5a776cf63d2..17eb94f94e50 100644 --- a/tests/gateway/test_slack.py +++ b/tests/gateway/test_slack.py @@ -7315,3 +7315,432 @@ class TestEnsureDmConversation: assert result.success is True post_kwargs = adapter._app.client.chat_postMessage.await_args.kwargs assert post_kwargs["channel"] == "D999NEW" + + +# --------------------------------------------------------------------------- +# TestThreadImageContext — C1-images: images/files in prior thread messages +# must be visible to the agent when it joins the conversation (#69185, +# #32315, #66136).
