## Alert Library A curated catalog at `/alert-library`: browse packs of ready-made alerts, see which ones can actually run against the streams this org already receives, preview a verdict against real data, and install one or many. The library is a **peer page** of Alerts / Notification Destinations / Templates — flat routing, presented as tabs via a shared `AlertSectionTabs` in `OPageLayout #header-tabs` (the pattern `PipelineSectionTabs` already ships). ### What landed, by phase | Phase | What | | --- | --- | | Data layer | S3 manifest fetch, cache, readiness resolution (`useAlertLibrary`, `constants/alertLibrary`, `types/alertLibrary`) | | Gallery | Rail (packs / categories, multi-select, segmented switch), stat-strip availability facets, cards | | Drawer | Detail view with query preview and customizable tunables | | Install | Bulk-install wizard — destination selection, per-alert tunables, stale-session hardening | | Prefill | Carry a library alert (query, trigger, threshold, severity) into the alert editor | ### Design decisions worth knowing - **Rail navigates, strip filters.** Availability is deliberately not in the rail — carrying both overflowed it and pushed a facet group below the fold. - **Colour marks the exception only.** No "Ready" pill (it would describe ~75 of 86 cards and signal nothing); only unusable cards carry a label. - **A failed `/streams` call leaves readiness unknown**, rather than claiming "none of your data matches" — that claim would be about the request, not the org, and it is the most alarming thing this page can say. Counts read `—` until there is an answer, and a failed *refresh* keeps the verdict it already had. - **No "Installed" tile** — installed detection doesn't exist yet, and a tile reading a permanent zero is dishonest UI. - **`severity: warning` renders as `medium`** — the badge group's scale is critical/high/medium/low/info, and medium is the amber it also gives P3, which is exactly the priority a warning alert installs as. - Pack and category names come from the manifest, so they render as `raw()` data — a pack added upstream needs no frontend release. ### Design-system changes (used by the library, applied app-wide) - **`warning-quiet` badge tone** — one variant whose values differ by theme: the soft amber wash in light, a neutral chip in dark. Neither the filled amber chip nor the neutral one was right in both, because the two ramps aren't symmetric. - **Border tokens now meet WCAG 2.1 SC 1.4.11.** Every border token measured under 3:1 (`border-strong` was 2.52:1). `border-default` firms to grey-300 and controls get a token that clears 3:1. - Nav: Reliability's flyout groups its four alerting entries under one **Alerts** header, declared in the same order as the tab strip those pages carry. Flyout levels are sized by depth. - `sensors-off` icon added to the `OIcon` registry. ### Fixes that rode along - **metrics**: a shared URL whose `metrics_data` blob omits panel query fields no longer blanks the whole metrics page — blob queries are filled out to the panel schema before being laid over. - **dashboards**: a PromQL series with no legend template was named `JSON.stringify(metric)`, so fifty series read identically for the width of the chip. Series are now named by the labels that actually differ, preferring the ones that say *which workload* it is (namespace / service / pod / host). Correlation's semantic groups refine that when loaded, but nothing is fetched to render a chart — that endpoint is enterprise-only and a chart must render the same on OSS. - **alerts**: preview evaluates against the alert's real trigger; deleting a row no longer reloads the list behind it; peer tabs no longer shift when switching alerting pages. - **ui**: badge-only select options no longer render bold. ### Tests - `test(search)`: pins the streaming-aggregate **wire contract** at the HTTP boundary. Under streaming aggregates each partition carries the cumulative merged state (last frame is the answer) while ordinary partitions are disjoint and must be summed. No pytest had ever received `streaming_aggs: true` — the emitter could have flipped to per-partition deltas with the whole suite green while dashboards, Logs and the alert preview all silently over-counted. - `test(e2e)`: four helpers that passed only while an org stayed small — an assertion reading past a 20-row page, an unfiltered `OSelect` that virtualises past 50 entries, a tab click landing on the rename pencil, and two builder tests asserting on whichever metric sorted first. - New unit specs across the library components, composable, facets, tunables and install path. ### Notes - **i18n**: en-US only; CI generates the other 14 locales. - **No backend changes** — this branch is entirely `web/` plus test helpers.
