## Summary
Wires up the launch flow: each waitlist lead gets a per-cohort
invitation email, a personal single-use Stripe promo code matching their
reward, and a signed landing link that unlocks register/install.
## Cohorts (resolved at send-time, by queue rank ASC, ignoring
`position` null/0)
| Cohort | Rule | Reward | Stripe coupon |
|---|---|---|---|
| `founder` | ranks 1–10 | Free forever | `wm_founder_forever` (100%
off, forever) |
| `founder_referrer` | referred any current founder (overrides rank) |
Free forever | `wm_founder_forever` |
| `early_bird` | ranks 11–100 | 2 mo free monthly / 3 mo free yearly
first year | `wm_earlybird_monthly` (100% off, 2 mo, monthly only) +
`wm_earlybird_yearly` (25% off once, yearly only) |
| `waitlist` | ranks 101+ | same as early bird | same coupons |
## What's added
- **DB**: `cohort`, `promo_code_monthly`, `promo_code_yearly`,
`invitation_sent_at` on `user_leads`.
- **Services**: `LeadCohortResolver`, `LeadPromoCodeAllocator`.
- **Commands**:
- `php artisan stripe:ensure-launch-coupons` — idempotent Stripe coupon
setup (run once per env).
- `php artisan leads:send-invitations --limit=N [--cohort=…] [--dry-run]
[--force]` — wave-by-wave delivery, idempotent across runs
(`invitation_sent_at` gate). Lazily generates Stripe promo codes per
lead it touches.
- **Checkout**: `SubscriptionController::checkout` resolves the auth
user's `UserLead` by email and applies the matching promo code
(`monthly`/`yearly`) via Cashier's `withPromotionCode()`.
- **Invite link**:
`LandingAuthOverrideService::generateInvitationUrl($leadId, days: 30)` —
signed lead-bound URL that unlocks auth buttons (existing override
cookie) and stores `invited_lead_id` in session. The register view
prefills the email from the lead.
- **Emails**: 4 cohort markdown templates (`founder`,
`founder-referrer`, `early-bird`, `waitlist`) with per-cohort subject +
body. Locale set from `$lead->preferredLocale()`. 28 Spanish keys added.
## Tests (Pest)
- `LeadCohortResolverTest` — boundaries + founder-referrer override +
null/0 position skip.
- `SendUserLeadInvitationsTest` — batch ordering, idempotent across
runs, ignores null/0, persists cohort.
- `UserLeadInvitationTest` — per-cohort body content, signed lead-bound
signup URL, Spanish locale.
- `LandingAuthOverrideTest` — invitation URL unlocks + stores session
lead.
Full suite green (1262 passed).
## Launch checklist
1. Merge + deploy.
2. `php artisan stripe:ensure-launch-coupons` against staging Stripe →
verify in dashboard → run on prod.
3. Optional preflight: `php artisan leads:send-invitations --limit=10
--dry-run`.
4. Wave-by-wave: `php artisan leads:send-invitations --limit=50` per
day.
5. Confirm `HIDE_AUTH_BUTTONS=true` on prod so only signed invite links
unlock register/install.
## Notes / non-goals
- No `User → UserLead` foreign key — checkout matches by email per
request.
- Existing `FOUNDER` promo flow is untouched and still kicks in if a
user has no lead-specific code.
- `founder_referrer` cohort is empty in current prod data; logic is in
place for when founders start referring.
## Summary
Mirror the real-estate historical-balance pattern for loan accounts.
When a loan is created with a current balance, linearly interpolate
monthly `account_balances` rows between the loan start date
(`original_amount`) and today (current balance).
## Approach
Since we don't know how the user actually paid down the loan, use simple
linear regression between two known points:
- `(start_date, original_amount)` from `loan_details`
- `(today, current_balance)` from the latest `account_balances` row
Rows are placed on the start date, the 1st of each intermediate month,
and today.
## Changes
- **`LoanBalanceGeneratorService`** — linear interpolation + upsert on
`(account_id, balance_date)` so existing rows aren't duplicated.
- **`GenerateHistoricalLoanBalancesJob`** — `ShouldQueue`, 3 tries, 10s
backoff. Takes account, original amount, start date, current balance,
from, to.
- **`Settings/AccountController::store`** (loan branch) — after creating
`loanDetail`, if a starting balance was provided: generate the last 12
months synchronously, dispatch older window to the queue when
`start_date` predates it.
- **`LoanDetailController::update`** — when the detail is first created
for an existing account, use the most recent `AccountBalance` as the
current value and apply the same sync/async split.
## Tests
- Service: interpolation, single-balance edge, future start_date, upsert
dedupe, monthly 1st placement, from/to range.
- Job: implements `ShouldQueue`, respects from/to range.
```
Tests: 8 passed (62 assertions)
```
No dependency or directory-structure changes.
## Summary
- **Auto-calculates Annual Revaluation %** (CAGR) on the frontend when
purchase price, purchase date, and current market value are all provided
— pre-fills the revaluation field while still allowing manual override
- **Generates historical monthly balance records** via linear
interpolation from purchase date to today when creating a real estate
account with complete purchase data
- New `RealEstateBalanceGeneratorService` handles balance generation
with dates on the 1st of each month (matching the existing
`ApplyRealEstateRevaluationCommand` convention)
## Changes
### Backend
- **`app/Services/RealEstateBalanceGeneratorService.php`** (new) —
Linear interpolation service that builds balance dates (purchase date,
1st of each intermediate month, today) and creates `AccountBalance`
records using `updateOrCreate`
- **`app/Http/Controllers/Settings/AccountController.php`** — Calls the
service after real estate detail creation when all three inputs are
present
### Frontend
- **`resources/js/components/accounts/account-form.tsx`** — Added CAGR
auto-calculation via `useEffect` with a `useRef` flag
(`isRevaluationManuallySet`) to avoid overwriting manual user input
### Tests
- **`tests/Feature/Services/RealEstateBalanceGeneratorServiceTest.php`**
(new) — 7 unit tests covering interpolation, edge cases (same-day
purchase, flat values, single month spans)
- **`tests/Feature/RealEstateTest.php`** — 6 new feature tests covering
historical balance generation through the controller (with/without
purchase data, same-day, flat values)
All 38 tests in `RealEstateTest.php` and all 7 service tests pass.
