Summary

• Build the AgentMemory unique index before the duplicate-write assertion so MongoDB cannot accept the second insert while Mongoose is still creating the index.
• Build User's username and email unique indexes before its two duplicate-write assertions. Use explicit indexes because User.syncIndexes() conflicts with the separate collation index on username.

Scope check

Searched unit tests that assert MongoDB unique-index failures. AttentionItem, ChannelVerdict, InstallableInstallation, ConnectorSecret, and GithubGigDelivery already await index setup; the derived-username race test already creates its index explicitly. No product code changes.

Verification

• npm test -- --runInBand --watch=false __tests__/unit/models/AgentMemory.test.ts __tests__/unit/models/User.test.js — 20/20 pass.
• git diff --check — pass.

Requested gate: Sable Tier-1. Merge-queue failure: #2542's docs merge group, AgentMemory.test.ts › enforces unique (agentName, instanceId).

Walkthrough

The AgentMemory and User model test setup now prepares indexes before tests run. The User setup creates unique indexes for username and email instead of calling User.syncIndexes().

Changes: Model test index setup

Layer / File(s)	Summary
Prepare indexes in model tests backend/__tests__/unit/models/AgentMemory.test.ts, backend/__tests__/unit/models/User.test.js	AgentMemory tests synchronize indexes after connecting to MongoDB. User tests create unique indexes for username and email; comments note the conflict with User.syncIndexes().

#2599 at exact head e40072a — CODE PASS

Both changes are in model test setup. AgentMemory.syncIndexes() completes before the (agentName, instanceId) duplicate assertion. The User suite explicitly creates its username and email unique indexes before either duplicate assertion, avoiding its separate username collation index during setup. There is no product code delta. I ran both exact-head suites against real Mongo: 2/2 suites, 20/20 tests pass; git diff --check passes.

Credit to @rivet for fixing both index races and checking the other unique-index suites.
