## Thinking Path > - Paperclip is the open source app people use to manage AI agents for work > - On Paperclip Cloud, each request resolves its board actor from trusted Cloud headers in `actorMiddleware` > - This runs for every request after the liveness probe, also for static files such as `favicon.ico` and `index.html` > - The resolution ran three database statements one after another: the stale `instance_admin` purge, the membership read and the owner-elevation read > - On a loaded database, each statement waits. Three sequential waits make every request slow, also a request that needs no data > - This pull request keeps the purge and the tenant sync in order and runs the two reads at the same time as them > - The benefit is one database wait per request instead of three ## Linked Issues or Issue Description **What existing behavior does this improve?** Cloud tenant actor resolution in `server/src/middleware/auth.ts` (`resolveCloudTenantActorOnce`). **Subsystem affected** Server authentication middleware (Cloud trusted-header path). **Current behavior** Measured on the hosted staging instance on 2026-11-09 from a signed-in browser, 45 paired samples in 40 s: - `/api/liveness` (mounted before actor resolution): client median 92 ms, p90 255 ms, server time ≤ 1 ms. - `/favicon.ico` with a session (after actor resolution): client median 413 ms, p90 1,751 ms, max 4.6 s. - `/api/cli-auth/me`: server median 346 ms, p90 1,528 ms. The same Node process answers liveness quickly, so the event loop is not blocked. The database is busy (6–8 of 8 vCPU for the whole day), and trivial primary-key reads waited 100–280 ms each. Three sequential reads explain the ~320 ms median gap between liveness and favicon. **Proposed behavior** The purge and the debounced tenant sync stay ordered. The membership read and the owner-elevation read run at the same time as them. The sync writes only the primary company's membership, and the membership read excludes that company, so the result does not change. **Reason and benefit** A synced request costs one database wait instead of three. With 150 ms of injected database latency, a synced resolution goes from 914 ms to 310 ms (3 runs each, same machine). **Breaking changes** None. ## What Changed - `resolveCloudTenantActorOnce` starts the purge-and-sync, the additional-membership read and `resolveOwnerInstanceAdmin` together and awaits them with `Promise.all`. A membership read failure still degrades to the primary company. The owner-elevation read still fails closed. - New regression test `server/src/__tests__/cloud-tenant-actor-round-trips.test.ts`. It connects through a TCP proxy that delays every client write by 150 ms and asserts that a synced resolution finishes in less than 4 × the delay. Before the change it takes about 6 × (914 ms); after the change about 2 × (310 ms). - `auth-session-route.test.ts`: the fake database binds each `returning()` to its own insert, and the test matches inserts by content instead of position, because the instance-settings insert can now happen in parallel with the tenant sync. ## Verification - `cd server && npx vitest run src/__tests__/cloud-tenant-actor-round-trips.test.ts` — red on `origin/master` (914 ms, 913 ms, 916 ms), green with the change (310 ms). - `cd server && npx vitest run src/__tests__/cloud-tenant-company-provisioning.test.ts src/__tests__/auth-session-route.test.ts src/__tests__/liveness.test.ts src/__tests__/cloud-warm-standby.test.ts src/middleware/cloud-tenant-actor.test.ts` - `pnpm verify` (selected tests), and CI. - After deploy: compare `/favicon.ico` and `/api/cli-auth/me` client time with `/api/liveness` on staging. Expect the median gap to drop from about 3 database waits to about 1. ## Risks - Low risk. Authorization does not change: the same statements run and the request waits for all of them before it continues. - Each request now uses up to three pooled connections at the same time instead of one. The staging pool limit is 500, so this is not a concern there. Smaller pools reach their limit sooner under a burst. - The diff re-indents the purge-and-sync block. The statements in it do not change. ## Model Used - Claude Opus 5.5 (`claude-opus-5-5`), Anthropic, via Claude Code with tool use (shell, browser, code execution).
