## Summary
The `homeNew` PostHog experiment has concluded. This PR graduates it by
making the new homepage (`ProjectHome`, formerly `HomeV2`) the permanent
default for all users, and removes all dead code from the old
experiment.
## Changes
- Remove `homeNew` PostHog feature flag checks and `home_new` experiment
exposure tracking from 3 files
- Rename `HomeNew/` → `ProjectHome/` directory and `HomeV2` →
`ProjectHome` export
- Delete old `Home/Home.tsx` component (shared components like
`ProjectList/` are kept — still used by org pages)
- Delete `pages/project/[ref]/building.tsx` and add a server-side
redirect from `/project/:ref/building` → `/project/:ref` to prevent 404s
during rollout (old cached JS bundles may still route to `/building`)
- Simplify `ContentWrapper` building-state logic in `ProjectLayout` —
always redirect building projects to home, always suppress building
interstitial on home page
- Always route to `/project/{ref}` after project creation (remove
`/building` path)
- Update all Observability imports from `HomeNew` → `ProjectHome`
## Self-hosted behavior change
Self-hosted Studio previously showed the old `Home` component (client
libraries + example projects) since PostHog flags don't load. This PR
changes self-hosted to show `ProjectHome` (TopSection with service
status + instance diagram, advisor, custom reports). All sections query
backend APIs that exist on self-hosted. E2E tests pass against the
self-hosted build.
## Testing
- [x] `pnpm turbo run build --filter=studio` passes
- [x] No remaining references to `homeNew`, `home_new`, or `HomeNew` in
codebase
- [x] No broken imports to deleted files
- [x] Self-hosted E2E tests pass (145 passed, 1 flaky, 4 skipped)
- [x] `/building` redirect added to both platform and self-hosted config
blocks
**Quick test:**
1. Navigate to any project homepage — should render the ProjectHome
component
2. Create a new project — should redirect to `/project/{ref}` (not
`/building`)
3. Visit a project in `COMING_UP` state on a non-home route — should
redirect to home
4. Visit `/project/{ref}/building` directly — should 302 redirect to
`/project/{ref}`
## Linear
- fixes GROWTH-671
## Context
Just cleaning up the `unifiedReplication` feature flag now that this is
fully rolled out
Also addresses some bugs that I came across while cleaning up,
specifically for the new home page
- Add enabled features flag check for read replicas in database
replication
- Infra diagram, read replicas
- View connection string CTA to open connect UI with the right database
selected
- Replaced all other actions with a "Manage replica" CTA which links to
the replica details page
## I have read the

file.
YES
## What kind of change does this PR introduce?
The changes required for this React Doctor need more thought that I can
hammer with AI. Just need to stop this from happening in the future with
Ratchet rules
This PR adds a new rule `no-restricted-imports` for deprecating old
packages. For now, only `react-data-grid` and `react-contexify` have
been added.
The ratchet baselines has been rerun with the new rules.
## Summary
Removes two concluded A/B experiments that didn't produce positive
results:
- **tableQuickstart**: Tested AI-powered table generation, template
selection, and assistant integration for new table creation
- **realtimeButtonVariant**: Tested hiding the realtime button or
replacing it with a triggers button
## Changes
- Delete `TableQuickstart/` folder with AI widget, templates widget, and
generation hooks
- Delete `useRealtimeExperiment` hook and remove variant-conditional
logic
- Delete `/api/ai/table-quickstart/generate-schemas` endpoint
- Remove telemetry event definitions for both experiments
- Remove local storage exposure tracking key
- Remove API endpoint from proxy whitelist
- Clean up eslint baseline references
## Testing
- [x] Tested locally - Table Editor renders correctly without experiment
widgets
- [x] TypeScript compiles without errors
- [x] No remaining references to removed experiment code
**Quick test:**
1. Navigate to Table Editor → New Tab shows only "Create a table" card
(no AI/Templates/Assistant variants)
2. Open table create panel → Realtime checkbox shows unconditionally
when realtime is enabled

* chore: add eslint ratchet script
* chore: add eslint ratchet action
* refactor(ratchet script): convert to typescript
* ci(ratchet script): add --decrease-baselines flag
Allows us to decrease the baselines on schedule as we fix warnings
* ci(ratchet): add action to decrease baseline if possible every week
* chore(eslint): fix exhaustive-deps error
* docs(internal): improve docs for eslint ratchet script
* chore(ratchet): add new ratchet rules
Add:
- import/no-anonymous-default-export
- @tanstack/query/exhaustive-deps
- @tanstack/query/no-deprecated-options
Not adding `no-restricted-exports` even though we have many violations
because we first need to reconfigure it (if possible) to ignore those
files where Next.js requires a default export.
