## Summary
Lets existing (non-onboarding) users discover and manage AI
categorization, gated behind a new Pennant feature flag. When a flagged
paid user grants consent, every uncategorized transaction is categorized
in the background with live, on-screen feedback.
Enable per user: `php artisan feature:enable AiConsentSettings
user@example.com`
## What's included
**Feature flag**
- New `AiConsentSettings` Pennant flag (off by default), exposed to the
frontend via the shared `features` prop.
**Billing settings (`/settings/billing`)**
- When the flag is active, a section to grant or revoke AI consent
(checkbox → `POST`/`DELETE /ai/consent`).
**Transactions page**
- A consent prompt rendered as the first row of the transactions table
(new `DataTable` `topRow` slot), styled with the shared gradient
`AiSparkleIcon`. Only shown to paid users with the flag who haven't
consented yet.
- An inline "Enable AI" button records consent without leaving the page.
**Backfill on consent**
- Granting consent dispatches a queued
`CategorizeUncategorizedTransactionsJob` that categorizes all of the
user's uncategorized transactions, **most recent first**, recording
progress in the cache.
- The transactions page polls a new status endpoint (`GET
/ai/categorization/{jobId}/status`): visible uncategorized rows show a
spinner + pulse while the backfill runs, categories stream in via
partial reloads, and a toast tracks `processed / total` until
completion.
## Notes / decisions
- **Polling, not websockets** — the project has no broadcasting
configured; this mirrors the existing `ReEvaluateTransactionRules` job +
status-endpoint pattern.
- The backfill job is kept separate from
`CategorizeOnboardingTransactionsJob` so the onboarding pass stays
progress-free (small, commented duplication).
- Reuses the existing `AiCategorizationGate` (config kill-switch + pro
plan + active consent) — free users and disabled-AI never dispatch the
job.
- Not included (YAGNI): cancelling an in-flight backfill on revoke;
persisting the spinner across full page reloads.
## Testing
- New Pest coverage: feature-flag exposure, billing/transactions consent
props, consent-triggered dispatch + gating, the status endpoint
(200/404), job progress recording, and recent-first ordering.
- `php artisan test --exclude-testsuite=Browser` passes (one unrelated,
pre-existing `DashboardTest` failure on `main`).
- Pint, Prettier and ESLint clean.
