## Summary
Scopes React Compiler diagnostics for component and hook effects that
intentionally synchronize with navigation, submissions, browser APIs,
streams, timers, or authoritative server values. Each suppression stays
on the reported synchronization call rather than disabling analysis for
the component.
## What
Wires the run-ops split into the webapp: database topology, environment
flags, split-mode gating, and the control-plane resolver/cache layer
that the run-store and run-engine seams from the previous PR plug into.
- **DB topology & env** (`apps/webapp/app/db.server.ts`,
`env.server.ts`, `entry.server.tsx`): adds the run-ops database
clients/topology and the environment variables that configure and gate
the split.
- **runOpsMigration module** (new
`apps/webapp/app/v3/runOpsMigration/`): the webapp-side machinery —
`splitMode.server.ts`, `controlPlaneResolver.server.ts` +
`controlPlaneCache.server.ts`, `readThrough.server.ts`,
`crossSeamGuard.server.ts`, `distinctDbSentinel.server.ts`, id-minting
helpers (`mintBatchFriendlyId`, `runOpsMintKind`,
`resolveInheritedMintKind`), `runOpsCascadeCleanup.server.ts`, the split
read gate, and route/unblock catalogs.
- **Store/engine wiring** (`app/v3/runStore.server.ts`,
`runEngine.server.ts`, `runEngineHandlers.server.ts` + new
`runEngineHandlersShared.server.ts`): points the webapp's store/engine
construction at the resolver, and factors shared handler logic out so
both seams use one path.
- **Read-path touch-ups**: `runtimeEnvironment.server.ts`,
`eventRepository/index.server.ts`, `taskRunHeartbeatFailed.server.ts`,
`engineVersion.server.ts` route their run/environment lookups
read-through the resolver.
- `413a94511` — interlocks split mode against the native realtime
backend so the two aren't enabled in an incompatible combination (see
`.server-changes/run-ops-split-realtime-interlock.md`).
- `dc74c57fd` — drops the earlier "known-migrated" read layer; residency
is determined by id-shape only.
## Why
PR5 of the run-ops split stack. This is the webapp foundation layer: it
stands up the DB topology, flags, and resolver/cache the rest of the
stack depends on, and repoints webapp read paths through the resolver.
Additive when the split is not enabled (existing single-DB behavior
preserved behind flags); behavior-changing on the read-through paths and
the realtime interlock.
## Tests
New vitest coverage across `apps/webapp/test/` and colocated
`*.server.test.ts` files: db topology, split mode, split read gate,
cross-seam guard, mint cutover / flip latency, control-plane cache,
control-plane resolver, distinct-db sentinel, read-through loaders
(route loaders, run-detail loaders, `findEnvironmentFromRun`), and the
run-engine handlers. Testcontainers-backed; no mocks. `pnpm-lock.yaml`
synced for the two new webapp deps.
## Notes
Draft, **stacked on #4116** (`runops/pr04-store-engine`). Review that
first; this diff is against it.
Server-change / changeset note to be added at stack-assembly time.

## Summary
- Adds admin-only editors on the back-office org page for
`Organization.maximumProjectCount` and
`Organization.batchRateLimitConfig`, alongside the existing API rate
limit editor.
- Splits the back-office org page into per-section components
(`ApiRateLimitSection`, `BatchRateLimitSection`, `MaxProjectsSection`)
so each tool is self-contained — adding new sections later doesn't bloat
the route.
- Generalizes the rate-limit form into a reusable `RateLimitSection`
component + `RateLimitDomain` server config so API and batch share the
same UI, validation, and action handler. Each domain only owns its env
defaults, DB column, and logger key.
- "Saved." banner and validation errors are scoped to the section that
submitted, not the page.
Heads-up: the API rate-limit log key was renamed
`admin.backOffice.rateLimit` → `admin.backOffice.apiRateLimit` for
symmetry with the new `admin.backOffice.batchRateLimit`.
## Test plan
- [ ] As an admin, visit `/admin/back-office/orgs/:orgId` and confirm
all three sections render with the org's current values (or system
defaults).
- [ ] Edit and save each section; confirm only that section shows the
"Saved." banner.
- [ ] Submit invalid input (e.g. `0` tokens, malformed interval);
confirm errors render in the offending form only and the other sections
stay closed.
- [ ] Confirm a non-admin user is redirected away from the route.
- [ ] After saving a rate-limit override, hit the org with traffic and
confirm the new limit is enforced (API rate limit + batch rate limit
code paths read the column at request time).
