feat(desktop): show typed links between inbox reports - #103927
posthog[bot] wants to merge 4 commits into
Conversation
Desktop and mobile dropped the `report_link` artefact into the unknown-type fallback, so a reader saw no relation, no reason, and no way to reach the related report. Model the artefact and its link-kind union in `@posthog/shared`, add a shared `reportLinkKindLabel` that humanizes a kind the client does not know, render the relation, reason and a link in the Desktop activity log, and add the equivalent mobile row with navigation to the linked report.

Fall back to the shared "Untitled report" label instead of the raw UUID, drop a redundant nullish coalescing and a redundant margin reset. Generated-By: PostHog Desktop Task-Id: 10761583-d97c-480b-8351-6a7d6ab6a55b

The api-client artefact normalizer had no `report_link` branch, so every link row fell through to the last-resort path and arrived marked degraded with its content replaced by a text preview. Desktop checks `degraded` before the type dispatch, so the new typed row would never have rendered. Add the normalizer, fix the test fixture typing that broke the typecheck, and let the mobile activity row fall back to the preview text on a degraded row, the way the Desktop log already does.

A link whose `report_id` is blank or not a UUID passed the normalizer and became a dead navigation target. Send it down the fallback path instead, so the reader gets the text preview. Also type the degraded-row test fixture as the `SignalReportArtefact` the fallback normalizer actually returns, rather than casting a link row into it.

Changes
report_link, body "No preview available."report_linkbranch. Without it every link row fell through to the last-resort path and arrived markeddegraded, so the typed row would never have rendered — the type addition alone does not fix the symptom.packages/sharedgains aReportLinkArtefactplus aReportLinkKindunion, and the artefact joinsAnySignalReportArtefact.reportLinkKindLabelin@posthog/coremaps the five known kinds and humanizes anything else, so a kind the backend adds later still reads as words rather than a raw enum./reports/$reportIdon Desktop,/inbox/<id>on mobile).||to a type set, and its row label from a ternary to a lookup.How did you test this code?
ArtefactLogList.test.tsxrenders the Desktop row and asserts the relation label, the reason, and thehrefof the link.

/writing-tests. It moved the link-kind label matrix out of a component render into a pure unit test and folded the remaining cases into existing blocks rather than adding standalone ones.report_linkwould render nothing on mobile — fixed, and following that thread surfaced the missing normalizer, which was the larger defect.Flex/Badgeto match the surrounding file; the desktop guide bans new Radix imports, so it was rewritten ondiv+ Tailwind + the inboxInboxBadge. The link also moved from/inbox/reports/$reportIdto the canonical/reports/$reportId, skipping a redirect hop.products/signals/backend/enums.pyin this repository; the test fixtures are invented.Created with PostHog Desktop from this inbox report.
