YES ## What kind of change does this PR introduce? Bug fix (telemetry correctness). No user-visible change. ## What is the current behavior? Linear: [GROWTH-1153](https://linear.app/supabase/issue/GROWTH-1153/telemetry-advisorcategory-omitted-for-health-lints-on-two-of-five) **Before:** five surfaces emit the optional `advisorCategory` property on `advisor_detail_opened` and `advisor_assistant_button_clicked`, and they disagree about how to derive it. Three pass the lint's category straight through as `categories[0]`. Two compute it with a hardcoded ladder — `categories.includes('SECURITY') ? 'SECURITY' : categories.includes('PERFORMANCE') ? 'PERFORMANCE' : undefined` — which predates the `HEALTH` category and falls through to `undefined` for anything it does not name. Because the property is optional, those two surfaces ship the event with `advisorCategory` silently absent: no type error, no runtime error, just a hole in the data. A reader querying a category breakdown of either event gets numbers that depend on which surface the user happened to click, and `HEALTH` is under-counted. The split is clearest in `AdvisorSection.tsx`, where a single advisor card emits both events — the card click through the ladder (L83) and the Assistant button through the pass-through (L206) — so one card can report two different categories for the same lint. The cause is that `AdvisorCategory` in `packages/common/telemetry-constants.ts` is schema-derived: ```ts type AdvisorCategory = components['schemas']['GetProjectLintsResponse'][number]['categories'][number] ``` The API-types regeneration in supabase/supabase #49646 (merged 2026-08-27, `26e89b36c349893540f8efbd45613921be0a4d18`) widened `categories` from `('PERFORMANCE' | 'SECURITY')[]` to `('PERFORMANCE' | 'SECURITY' | 'HEALTH')[]`. `AdvisorCategory` picked up the third value incidentally and the two ladders were never updated — a union widening is invisible to a hardcoded ladder, so nothing broke loudly. | Event | Surface | HEALTH behavior before | | --- | --- | --- | | `advisor_detail_opened` | `apps/studio/components/ui/AdvisorPanel/AdvisorPanel.tsx` (L203) | ladder → property absent | | `advisor_detail_opened` | `apps/studio/components/interfaces/ProjectHome/AdvisorSection.tsx` (L83) | ladder → property absent | | `advisor_detail_opened` | `apps/studio/components/interfaces/Linter/LinterDataGrid.tsx` (L163) | pass-through → `'HEALTH'` | | `advisor_assistant_button_clicked` | `apps/studio/components/interfaces/Linter/LintDetail.tsx` (L38) | pass-through → `'HEALTH'` | | `advisor_assistant_button_clicked` | `apps/studio/components/interfaces/ProjectHome/AdvisorSection.tsx` (L206) | pass-through → `'HEALTH'` | The two `advisorCategory` property doc comments in `telemetry-constants.ts` (L2949, L2980) also still read "Category of the advisor (SECURITY or PERFORMANCE)", which the widening made false. ## What is the new behavior? **After:** all five surfaces derive `advisorCategory` the same way, so a category breakdown of these two events is consistent regardless of which surface produced the event, and `HEALTH` is reported wherever it can occur. The two ladder sites now read `item.original.categories[0]`, matching the three sites that already did. The `signal` branch (which reports `'SECURITY'`) and the `notification` branch (`undefined`) of those two expressions are unchanged, so nothing about non-lint advisor items moves. The stale parenthetical is cut from both doc comments. Net diff is 3 files, -12/+4 lines. No behavior change outside the value of one optional telemetry property. ## Additional context **How.** The fix is the pass-through, not an extended ladder. Per the two options considered: 1. **No lint carries more than one category in practice.** Every lint fixture in `apps/studio` uses a single-element array (`['SECURITY']`, `['PERFORMANCE']`). The API type permits a multi-element array, but nothing in the repo produces one, so the ladder's SECURITY-over-PERFORMANCE priority is not load-bearing. 2. **The advisors UI already treats the first element as canonical** — `LinterDataGrid.tsx` L196 renders `<LintCategoryBadge category={selectedLint.categories[0]} />`. 3. **Extending the ladder would not actually produce agreement.** In the one reachable multi-category case, a ladder with a `HEALTH` branch appended still reports the higher-priority category while the three pass-through sites report `categories[0]`. Only `categories[0]` makes all five agree, which is the point of the change. **Reviewers should look at this first — how much data is actually affected.** Narrower than the headline suggests, and worth stating precisely. Every surface feeding these events filters lints upstream by category, and all three filters still admit only `SECURITY` or `PERFORMANCE`: - `AdvisorPanel.utils.ts` `createAdvisorLintItems` drops any lint that resolves to no tab (`if (!tab) return null`), and it is the item source for **both** ladder surfaces - `pages/project/[ref]/advisors/security.tsx` filters `categories.includes('SECURITY')` - `pages/project/[ref]/advisors/performance.tsx` filters `categories.includes('PERFORMANCE')` So a HEALTH-**only** lint is not surfaced anywhere in Studio today and cannot currently reach any of the five emit sites. The divergence reachable today is a lint carrying `HEALTH` alongside another category: it passes the filters, and then the ladder sites and the pass-through sites disagree. The HEALTH-only omission is latent, and becomes live data loss the moment HEALTH lints are surfaced — presumably the point of the API adding the category. Practical consequence: **no backfill or historical-data caveat is needed**, because no HEALTH-only event was ever emitted. This is a correctness fix that gets the emit surfaces right ahead of the category being shown, not a response to an active data incident. **How it was tested.** Honest caveat up front: `pnpm install` cannot complete in this sandbox, so the Studio-scoped checks could not be run here. `apps/studio` depends on `@std/path` → `npm:@jsr/std__path`, and the JSR registry is network-blocked in this environment (`GET https://npm.jsr.io/~/11/@jsr/std__path/1.0.8.tgz` → `403`, both direct and proxied; `registry.npmjs.org` returns `200`, so it is JSR specifically). CI on this PR is the real signal for Studio lint, typecheck, and tests. What did run clean: - `prettier --config prettier.config.mjs --check` on all three changed files — clean - `tsc --noEmit` in `packages/common` (installed via `pnpm install --filter=common...`) — clean, and `--listFiles` confirms it genuinely covers both `telemetry-constants.ts` and the widened `packages/api-types/types/platform.d.ts` - the changed expression typechecked in a standalone harness against the real generated `components['schemas']['GetProjectLintsResponse']`, confirming `categories[0]` is assignable to `AdvisorCategory | undefined` — with a negative control that correctly errored (`Type '"HEALTH"' is not assignable to type '"PERFORMANCE" | "SECURITY" | undefined'`) to prove the harness had teeth No tests are added. There is no existing test coverage of `handleItemClick` / `handleCardClick` in either ladder component, and the change is a narrowing of one expression to match three existing call sites rather than new logic. Asserting an emitted property value would require standing up component tests for two components that have none, which is a larger piece of work than this fix and better done as its own change. **Suggested follow-up, deliberately not in this PR.** `createAdvisorLintItems` and the two advisors pages filter HEALTH lints out entirely, so the category the API now returns is invisible in Studio. Whether to surface it is a product decision about a new advisor category, not a telemetry fix. Also out of scope by request: `Linter.utils.tsx` badge styling (HEALTH falling back to PERFORMANCE's badge is harmless). --- _Generated by [Claude Code](https://claude.ai/code/session_01Xwj2SotnaHByjbTfqF4Kdm)_ Co-authored-by: Claude <noreply@anthropic.com> Co-authored-by: Pamela Chia <pamelachiamayyee@gmail.com>
Supabase Studio
A dashboard for managing your self-hosted Supabase project, and used on our hosted platform. Built with:
What's included
Studio is designed to work with existing deployments - either the local hosted, docker setup, or our CLI. It is not intended for managing the deployment and administration of projects - that's out of scope.
As such, the features exposed on Studio for existing deployments are limited to those which manage your database:
- Table & SQL editors
- Saved queries are unavailable
- Database management
- Policies, roles, extensions, replication
- API documentation
Managing Project Settings
Project settings are managed outside of the Dashboard. If you use docker compose, you should manage the settings in your docker-compose file. If you're deploying Supabase to your own cloud, you should store your secrets and env vars in a vault or secrets manager.
How to contribute?
- Branch from
masterand name your branches with the following structure{type}/{branch_name}- Type:
chore | fix | feature - The branch name is arbitrary — just make sure it summarizes the work.
- Type:
- When you send a PR to
master, it will automatically tag members of the frontend team for review. - Review the main contributing guide to help test your feature before sending a PR.
- The Dashboard is under active development. You should run
git pullfrequently to make sure you're up to date.
