no-effect-promise

Intent: a promise that can reject is lifted with Effect.tryPromise, not Effect.promise.

// ❌ no
Effect.promise(() => client.connect())

// ✅ yes
Effect.tryPromise({ try: () => client.connect(), catch: toConnectionError })

Trigger: Effect.promise outside the release step of acquireRelease, acquireUseRelease and addFinalizer.

Exemptions and blind spots: the release step, where a promise that cannot reject is the normal case. Test files, where a rejection during setup is a broken test and the defect fails it with the cause. Elsewhere, a promise that truly cannot reject must be suppressed by hand.

Why: Effect.promise turns a rejection into a defect.

Options:

• testFiles: shared setting, see Shared settings.

Fix: none
