+The Where host targets have three explicit schemes — **Where Development**
+(`Debug`), **Where Beta** (`Beta`), and **Where App Store** (`Release`) — whose
+audience descriptors live in [`Project.swift`](Project.swift). Keep bundle IDs,
+App Group, display name, primary icon, configuration, and the matching
+`WHERE_DEVELOPMENT` / `WHERE_BETA` / `WHERE_APP_STORE` compiler condition in
+that one descriptor. These custom conditions belong only to the app, widget,
+and share-extension targets; package targets receive audience-dependent values
+by injection. Development uses its own bundle family and local-only store;
+Beta and App Store share the production bundle family and CloudKit store.

   `AGENTS.md` says what it is and how it can be used.
 - Add SPM library targets in `Package.swift` and wire apps/tests in `Project.swift` (see existing `unitTests` helper. Native-macOS test bundles are declared directly, like `LedgerCoreTests`, since that helper hosts iOS bundles in StuffTestHost). A new module also ships a root `README.md` and `AGENTS.md` — see [Per-module docs](#per-module-docs).
 - **CI schemes**: CI runs explicit shared schemes rather than the autogenerated `Stuff-Workspace` scheme. **Stuff-iOS-Tests** covers the iOS bundles. **Ledger-macOS-Tests** (the Ledger app + `LedgerCoreTests`) runs in its own `test-macos` job. The workspace mixes iOS targets with the native-macOS **Ledger** ones. No single xcodebuild destination can build both. Add a new test bundle to the matching scheme in `Project.swift`. If you do not, CI will not run it.
-- **CircleCI build handoff**: CircleCI builds both iOS schemes sequentially on one `m4pro.large` builder. The unit worker and parallel snapshot workers attach its products and run without compilation. Each worker validates the build manifest before it starts a simulator. `./snapshot-shards` owns three planned suite assignments and one intake shard. A new suite runs on the intake shard until rebalancing adds it to the plan. Each active snapshot worker must execute exactly its assigned suites.
+- **CircleCI build handoff**: CircleCI builds both iOS test schemes sequentially on one `m4pro.large` builder. The unit worker and parallel snapshot workers use its products without compilation. Each test worker validates the build manifest before it starts a simulator. Two `m4pro.medium` build-only shards compile **Where Beta** and **Where App Store** after the shared builder completes. `./snapshot-shards` owns three planned suite assignments and one intake shard. A new suite runs on the intake shard until rebalancing adds it to the plan. Each active snapshot worker must execute exactly its assigned suites.
 - **Image snapshots are the exception: one bundle per module, one shared scheme.** Each module owning image references has its own `*SnapshotTests` target over its `SnapshotTests/` folder. All are listed in the single shared **StuffSnapshotTests** scheme and its dedicated CI `snapshot` job. Snapshots are slow and LFS-backed. They are **out of** `Stuff-iOS-Tests`. References under any `__Snapshots__/` directory are Git LFS (`.gitattributes`. The CI job hydrates them explicitly). Framework halves: `Shared/SnapshotKit` (shippable matrix + previews) and `Shared/SnapshotKitTesting` (test-only pipeline, whose own regression bundle **SnapshotKitTestingTests** pixel-probes without LFS and runs in `Stuff-iOS-Tests`).
 - **A new image suite gets a target, not a scheme.** Add the `*SnapshotTests` target. List only `SnapshotKitTesting` in `extraPackageProducts`. Add it to the `StuffSnapshotTests` scheme's build and test lists. Never add a scheme or CI job of its own. An image bundle links only what its module needs (the Periscope and Inspector suites don't build against WhereUI at all). References follow the sources automatically via `#filePath`.
 - **Separate snapshot bundles are safe because each `.xctest` gets its own `StuffTestHost` process** (measured on Xcode 27 — `ProcessInfo.processIdentifier` probes. Details in the snapshot-bundle comment in [`Project.swift`](Project.swift)). Each bundle statically embeds its own copy of `SnapshotKitTesting`'s capture state. Two copies in one process corrupt each other. Tripwire: if a toolchain ever shares one host process across bundles, re-measure before adding another image bundle.
