feat: admin invite codes with plan assignment + user detail page

- Migration 030: add email, assigned_plan, trial_duration_days, email_sent_at
  to invite_codes with CHECK constraints
- Resend email integration (graceful degradation when API key not set)
- Invite codes now support plan assignment (free/pro/team) and trial duration (1-90 days)
- Registration applies invite code plan/trial to new subscription
- Auto-downgrade expired trials on authenticated access
- Enriched GET /admin/users/{id} with account, subscription, sessions, audit logs
- New endpoints: PUT /admin/users/{id}/subscription/plan and extend-trial
- Frontend: enhanced invite codes page with email, plan, trial fields
- Frontend: new user detail page at /admin/users/:userId
- Fixed API path drift: /invite-codes -> /invites
- 11 new backend tests, 416 total passing

# Admin Panel: Invite Codes + User Management Enhancement
## Context
The admin panel has basic invite code CRUD and user listing, but lacks:
- **Plan assignment on invite codes** — all registrations get "free" plan
- **Email delivery** — admin must manually copy/send codes
- **Trial duration** — no time-limited plan access for beta testers
- **User detail page** — no way to view/manage a user's subscription, activity, or trial
This change enables the admin to create invite codes tied to specific plans (free/pro/team) with optional trial durations, send branded invite emails via Resend, and manage user subscriptions from a detailed user page.
---
## Phase 1: Database Migration (030)
**New file:** `backend/alembic/versions/030_enhance_invite_codes.py`
Add columns to `invite_codes`:
- `email` (String(255), nullable, indexed)
- `assigned_plan` (String(50), nullable, default `'free'`, CHECK `free/pro/team`)
- `trial_duration_days` (Integer, nullable)
- `email_sent_at` (DateTime(timezone=True), nullable)
**Update:** `backend/app/models/invite_code.py` — add fields + `has_trial` and `email_sent` properties
---
## Phase 2: Resend Email Integration
**New file:** `backend/app/core/email.py`
- `EmailService` class with `send_invite_email(to, code, plan, trial_days)`
- Graceful degradation: if `RESEND_API_KEY` not set, log warning, skip sending
- Email failure doesn't block invite creation (best-effort)
**New file:** `backend/app/templates/invite_email.html`
- Branded HTML email: monochrome design, ResolutionFlow logo, CTA button
- Shows invite code, plan name, trial duration if applicable, signup link
**Update:** `backend/app/core/config.py` — add `RESEND_API_KEY`, `FROM_EMAIL`, `email_enabled` property
**Update:** `backend/requirements.txt` — add `resend`
**Env vars:** `RESEND_API_KEY`, `FROM_EMAIL=ResolutionFlow <invites@resolutionflow.com>`
---
## Phase 3: Backend API Changes
### Invite code enhancements
**Update:** `backend/app/schemas/invite_code.py`
- `InviteCodeCreate`: add `email`, `assigned_plan`, `trial_duration_days`
- `InviteCodeResponse`: add new fields + computed `has_trial`, `email_sent`
**Update:** `backend/app/api/endpoints/invite.py`
- `create_invite_code`: accept new fields, send email if email provided, set `email_sent_at`, audit log
### Registration plan assignment
**Update:** `backend/app/api/endpoints/auth.py` (lines 178-183)
- When `invite_code_record` has `assigned_plan`/`trial_duration_days`, apply to new subscription
- Set `plan=invite_code_record.assigned_plan`, `status='trialing'` if trial, calculate `current_period_end`
### Subscription management endpoints
**Update:** `backend/app/api/endpoints/admin.py`
- `PUT /admin/users/{id}/subscription/plan` — change plan
- `PUT /admin/users/{id}/subscription/extend-trial` — add days to trial
- `GET /admin/users/{id}/detail` — enhanced user detail with account, subscription, sessions, audit logs, invite code used
**New file:** `backend/app/schemas/subscription.py``SubscriptionPlanUpdate`, `ExtendTrialRequest`, `SubscriptionResponse`
**New file:** `backend/app/schemas/user_detail.py``UserDetailResponse`, `SessionSummary`, `AuditLogSummary`, `AccountSummary`
### Trial expiry on login (lightweight)
**Update:** `backend/app/api/deps.py` — in `get_current_active_user`, check if subscription is trialing and expired → auto-downgrade to free
---
## Phase 4: Frontend Types & API Client
**Update:** `frontend/src/types/admin.ts`
- Enhanced `InviteCodeResponse` with email/plan/trial fields
- New: `UserDetail`, `SubscriptionDetail`, `SessionSummary`, `AuditLogSummary`, `AccountSummary`
**Update:** `frontend/src/api/admin.ts`
- Enhanced `createInviteCode` with new fields
- New: `getUserDetail`, `updateUserSubscriptionPlan`, `extendUserTrial`
---
## Phase 5: Frontend — Enhanced Invite Codes Page
**Update:** `frontend/src/pages/admin/InviteCodesPage.tsx`
Create form additions:
- Email input (optional, validated)
- Plan selector dropdown (Free / Pro / Team)
- Trial duration input (number of days, shown only if plan != free)
Table additions:
- "Recipient" column (email or "—")
- "Plan" column with badge
- "Trial" column (days or "—")
- "Email Sent" indicator
---
## Phase 6: Frontend — User Detail Page
**New file:** `frontend/src/pages/admin/UserDetailPage.tsx`
Sections:
1. **Header** — name, email, role badges, active status
2. **Account & Subscription card** — plan, status, trial end date, account display code
3. **Admin Actions card** — Change Role, Change Plan, Extend Trial, Activate/Deactivate (modal-based)
4. **Recent Sessions tab** — tree name, started, completed, outcome
5. **Audit Logs tab** — action, resource, timestamp, expandable details
6. **Invite Code card** — code used, plan assigned, who created it
**Update:** `frontend/src/router.tsx` — add route `admin/users/:userId`
**Update:** `frontend/src/pages/admin/UsersPage.tsx` — make user rows clickable → navigate to detail page
---
## Implementation Order
1. Migration 030 (invite code fields)
2. Model update (invite_code.py)
3. Resend integration (email.py, config.py, template, requirements.txt)
4. Backend schemas (invite_code, subscription, user_detail)
5. Backend API (invite.py, auth.py, admin.py, deps.py)
6. Backend tests
7. Frontend types + API client
8. Frontend invite codes page enhancement
9. Frontend user detail page
10. End-to-end testing

1. **Backend tests:** Create invite with plan+trial → register with code → verify subscription has correct plan/status/period_end
2. **Email test:** Mock Resend, verify template renders, verify email_sent_at set on success
3. **Trial expiry:** Create expired trial → login → verify auto-downgrade to free
4. **Admin UI:** Create invite with email+plan+trial → verify email sent → register → verify in user detail page → change plan → extend trial
5. **Build:** `cd frontend && npm run build` passes
6. **Full test suite:** `cd backend && pytest --override-ini="addopts="` passes

# Admin Panel: Invite Codes + User Management Enhancement
Date: 2026-02-12
Status: Proposed
## Summary
Enhance admin capabilities to:
1. Create invite codes tied to plans (`free`, `pro`, `team`) with optional trial durations.
2. Send invite emails via Resend (best-effort, non-blocking).
3. Apply invite-assigned plan/trial on registration.
4. Give admins a detailed user management view with subscription/session/audit context.
5. Support admin subscription actions (change plan, extend/start trial).
6. Auto-downgrade expired trials during authenticated access checks.
## Goals
- Remove manual invite-code sharing workflow.
- Support controlled beta onboarding with plan + trial at invite level.
- Enable operational admin workflows for account/subscription lifecycle.
- Keep backward compatibility where practical and avoid unsafe breaking changes.
## Non-Goals
- Stripe billing workflow redesign.
- Full historical pagination for user-detail sessions/audits in this iteration.
- Rework of account invite (`/accounts/me/invites`) flow.
## Key Decisions Locked
- Invite API path standardization: use `/invites` (frontend and backend aligned).
- User detail endpoint: enrich existing `GET /admin/users/{id}`.
- Invite `email` is advisory only (no strict email-match enforcement at registration).
- Invite plan/trial applies whenever a valid invite code is provided, even if `REQUIRE_INVITE_CODE=false`.
- Trial duration bounds: `1..90` days.
- Extend trial endpoint may convert non-trialing subscriptions to `trialing`.
- User detail payload includes recent summaries (latest 10 sessions + latest 10 audit logs) plus total counts.
## Scope by Phase
## Phase 1: Database Migration (`030`)
Create `backend/alembic/versions/030_enhance_invite_codes.py` (down revision `029`).
Add to `invite_codes`:
- `email`: `String(255)`, nullable, indexed.
- `assigned_plan`: `String(50)`, non-null, server default `'free'`.
- `trial_duration_days`: `Integer`, nullable.
- `email_sent_at`: `DateTime(timezone=True)`, nullable.
Constraints:
- `assigned_plan IN ('free','pro','team')`.
- `trial_duration_days IS NULL OR trial_duration_days BETWEEN 1 AND 90`.
- Optional consistency guard: `assigned_plan='free'` implies `trial_duration_days IS NULL`.
Update model `backend/app/models/invite_code.py`:
- Add mapped columns above.
- Add computed properties:
- `has_trial: bool` (`trial_duration_days is not None and > 0`)
- `email_sent: bool` (`email_sent_at is not None`)
## Phase 2: Resend Email Integration
Create `backend/app/core/email.py`:
- `EmailService.send_invite_email(to_email, code, plan, trial_days, signup_url) -> bool`.
- Returns `False` if `RESEND_API_KEY` missing.
- Catches provider failures and returns `False` (logs warning/error).
- Never blocks invite creation.
Create `backend/app/templates/invite_email.html`:
- Monochrome branded HTML.
- Invite code, plan, optional trial text, signup CTA button.
Update `backend/app/core/config.py`:
- `RESEND_API_KEY: Optional[str] = None`
- `FROM_EMAIL: str = "ResolutionFlow <invites@resolutionflow.com>"`
- `email_enabled` property.
Update `backend/requirements.txt`:
- Add `resend` package.
## Phase 3: Backend Schemas + Endpoints
### Invite code schemas
Update `backend/app/schemas/invite_code.py`:
- `InviteCodeCreate` adds:
- `email: Optional[EmailStr]`
- `assigned_plan: Literal['free','pro','team'] = 'free'`
- `trial_duration_days: Optional[int]` (1..90)
- `InviteCodeResponse` adds:
- `email`, `assigned_plan`, `trial_duration_days`, `email_sent_at`
- computed flags `has_trial`, `email_sent`.
### Invite endpoints
Update `backend/app/api/endpoints/invite.py`:
- `POST /invites` accepts new fields.
- Creates invite with plan/trial/email metadata.
- If email provided, attempts send:
- on success: set `email_sent_at`.
- on failure: invite still returns 201.
- Add audit log for invite creation with delivery result.
- Keep `GET /invites`, `DELETE /invites/{code}`, `GET /invites/validate/{code}` behavior compatible.
### Registration plan assignment
Update `backend/app/api/endpoints/auth.py`:
- If invite code is supplied and valid, load it and apply invite plan/trial regardless of `REQUIRE_INVITE_CODE`.
- For non-account-invite registrations:
- create subscription `plan=invite_code.assigned_plan` (fallback `free`).
- if `trial_duration_days` set:
- `status='trialing'`
- `current_period_start=now`
- `current_period_end=now + trial_duration_days`.
- else `status='active'`.
- Preserve account-invite join flow behavior.
- Mark invite as used post user creation.
### Admin subscription + detail endpoints
Update `backend/app/api/endpoints/admin.py`:
- Enrich `GET /admin/users/{id}` response:
- base user fields
- account summary
- subscription summary
- recent sessions (10) + total count
- recent audit logs (10) + total count
- invite code used summary
- Add:
- `PUT /admin/users/{id}/subscription/plan`
- `PUT /admin/users/{id}/subscription/extend-trial`
### Trial expiry check
Update `backend/app/api/deps.py`:
- In `get_current_active_user`, check account subscription.
- If `status='trialing'` and expired, auto-downgrade:
- `plan='free'`, `status='active'`
- clear/normalize trial period fields
- commit before returning user.
## Phase 4: Backend Schema Additions
Use existing file `backend/app/schemas/subscription.py` (do not duplicate):
- Add `SubscriptionPlanUpdate`.
- Add `ExtendTrialRequest`.
- Keep/extend `SubscriptionResponse` as needed.
Create `backend/app/schemas/user_detail.py`:
- `AccountSummary`
- `SessionSummary`
- `AuditLogSummary`
- `InviteCodeUsedSummary`
- `UserDetailResponse` (superset for enriched `/admin/users/{id}`).
## Phase 5: Frontend Types + API Client
Update `frontend/src/types/admin.ts`:
- Invite response fields for email/plan/trial/email-sent metadata.
- New detail types:
- `UserDetail`
- `SubscriptionDetail`
- `SessionSummary`
- `AuditLogSummary`
- `AccountSummary`.
Update `frontend/src/api/admin.ts`:
- Switch invite endpoints to `/invites`.
- Enhance `createInviteCode` payload.
- Add:
- `getUserDetail(userId)`
- `updateUserSubscriptionPlan(userId, plan)`
- `extendUserTrial(userId, days)`.
## Phase 6: Frontend Invite Codes Page
Update `frontend/src/pages/admin/InviteCodesPage.tsx`:
- Create form fields:
- optional email
- plan selector (Free/Pro/Team)
- trial days input when plan != free
- Table additions:
- recipient
- plan badge
- trial column
- email sent indicator
- Preserve existing create/copy/delete actions and status badges.
## Phase 7: Frontend User Detail Page
Create `frontend/src/pages/admin/UserDetailPage.tsx`:
- Header: name/email/role/active.
- Account & subscription card.
- Admin actions:
- change role
- change plan
- extend/start trial
- activate/deactivate
- Tabs:
- recent sessions
- audit logs
- Invite code card:
- code, assigned plan, creator.
Update `frontend/src/router.tsx`:
- Add route `admin/users/:userId`.
Update `frontend/src/pages/admin/UsersPage.tsx`:
- Make rows navigate to detail.
- Ensure action menu clicks do not trigger row navigation.
## API / Interface Changes
### Modified
- `POST /invites`
- new request fields: `email`, `assigned_plan`, `trial_duration_days`.
- `GET /invites`
- new response fields: `email`, `assigned_plan`, `trial_duration_days`, `email_sent_at`, `has_trial`, `email_sent`.
- `GET /admin/users/{id}`
- enriched response with account/subscription/recent activity details.
### Added
- `PUT /admin/users/{id}/subscription/plan`
- `PUT /admin/users/{id}/subscription/extend-trial`
## Test Plan
## Backend tests
1. Invite create with `assigned_plan + trial_duration_days` persists correctly.
2. Invite create with email:
- Resend success sets `email_sent_at`.
- Resend failure still returns 201 and does not set `email_sent_at`.
3. Registration with invite applies correct subscription plan/status/period fields.
4. Registration with optional invite (`REQUIRE_INVITE_CODE=false`) still applies plan/trial.
5. Expired trial auto-downgrades on authenticated request.
6. Admin plan update endpoint updates subscription + audit logs.
7. Admin extend-trial endpoint converts/extends correctly + audit logs.
8. Enriched `GET /admin/users/{id}` returns expected shape and list-size caps.
## Frontend verification
1. Create invite with email + plan + trial from admin UI.
2. Confirm invite table renders recipient/plan/trial/email-sent.
3. Open user detail from users table.
4. Change plan and extend trial from detail page.
5. Confirm updated values refresh in UI.
6. `npm run build` passes.
## Commands
- `cd backend && pytest --override-ini="addopts="`
- `cd frontend && npm run build`
## Risks and Mitigations
- Endpoint drift (`/invite-codes` vs `/invites`): update admin API client and validate all admin invite calls.
- Subscription side-effects in auth/deps: centralize trial-expiry logic and cover with tests.
- Payload growth for user detail: cap related arrays at 10 and include totals.
- Email provider outages: best-effort send with logging, no invite creation failure.
## Rollout
1. Deploy migration and backend changes.
2. Validate admin invite creation and registration path in staging.
3. Deploy frontend with new invite/user-detail UI.
4. Monitor audit logs and invite email delivery behavior post-release.
## Assumptions
- Existing admin access control (`require_admin`) remains unchanged.
- Plan limits for `free/pro/team` are already configured in `plan_limits`.
- No mandatory template engine addition is required for this email template rendering path.

# Admin Panel: Invite Codes + User Management Enhancement
**Date:** 2026-02-12
**Status:** Proposed — Combined Plan
---
## Summary
Enhance admin capabilities to:
1. Create invite codes tied to plans (`free`, `pro`, `team`) with optional trial durations.
2. Send invite emails via Resend (best-effort, non-blocking).
3. Apply invite-assigned plan/trial on registration.
4. Give admins a detailed user management view with subscription, session, and audit context.
5. Support admin subscription actions (change plan, extend/start trial).
6. Auto-downgrade expired trials during authenticated access checks.
---
## Goals
- Remove manual invite-code sharing workflow.
- Support controlled beta onboarding with plan + trial at invite level.
- Enable operational admin workflows for account/subscription lifecycle.
- Keep backward compatibility where practical and avoid unsafe breaking changes.
---
## Non-Goals
- Stripe billing workflow redesign.
- Full historical pagination for user-detail sessions/audits in this iteration.
- Rework of account invite (`/accounts/me/invites`) flow.
---
## Key Decisions Locked
| Decision | Choice | Rationale |
|----------|--------|-----------|
| Invite API path | Standardize on `/invites` | Already in use (`router = APIRouter(prefix="/invites")`). Update CLAUDE.md which incorrectly references `/invite-codes`. |
| User detail endpoint | Enrich existing `GET /admin/users/{id}` | One endpoint, richer response. No reason for admin to get a "lite" version. |
| Invite email matching | Advisory only (no strict enforcement) | The invite code itself is the security gate. Email is for admin tracking. Strict matching creates friction during beta. |
| Invite plan/trial application | Applies whenever a valid invite code is provided, even if `REQUIRE_INVITE_CODE=false` | Ensures plan/trial always carries through regardless of registration policy. |
| Trial duration bounds | 190 days | 90 days covers any realistic beta period. Protects against typos. Admin can always extend after expiry. |
| Extend trial behavior | May convert non-trialing subscriptions to `trialing` | Admin should have maximum control. Covers scenarios like forgotten trial assignment or second chances. |
| User detail payload | Recent summaries (latest 10 sessions + 10 audit logs) + total counts | Balances useful at-a-glance admin view with response performance. Full history via future paginated endpoints. |
---
## Phase 1: Database Migration (030)
**New file:** `backend/alembic/versions/030_enhance_invite_codes.py` (down revision `029`)
Add columns to `invite_codes`:
- `email`: `String(255)`, nullable, indexed.
- `assigned_plan`: `String(50)`, non-null, server default `'free'`.
- `trial_duration_days`: `Integer`, nullable.
- `email_sent_at`: `DateTime(timezone=True)`, nullable.
Database constraints:
- `assigned_plan IN ('free', 'pro', 'team')`.
- `trial_duration_days IS NULL OR trial_duration_days BETWEEN 1 AND 90`.
- Consistency guard: `assigned_plan = 'free'` implies `trial_duration_days IS NULL`.
**Update:** `backend/app/models/invite_code.py`
- Add mapped columns for all new fields.
- Add computed properties:
- `has_trial: bool``trial_duration_days is not None and > 0`
- `email_sent: bool``email_sent_at is not None`
---
## Phase 2: Resend Email Integration
**New file:** `backend/app/core/email.py`
- `EmailService` class with `send_invite_email(to_email, code, plan, trial_days, signup_url) -> bool`.
- Returns `False` if `RESEND_API_KEY` not set (graceful degradation).
- Catches provider failures, returns `False`, logs warning/error.
- Never blocks invite creation (best-effort delivery).
**New file:** `backend/app/templates/invite_email.html`
- Branded HTML email: monochrome design, ResolutionFlow logo, CTA button.
- Shows invite code, plan name, trial duration if applicable, signup link.
**Update:** `backend/app/core/config.py`
- Add `RESEND_API_KEY: Optional[str] = None`
- Add `FROM_EMAIL: str = "ResolutionFlow <invites@resolutionflow.com>"`
- Add `email_enabled` computed property.
**Update:** `backend/requirements.txt` — add `resend` package.
**Env vars required:** `RESEND_API_KEY`, `FROM_EMAIL` (has default).
**Prerequisite:** DNS records (SPF, DKIM) must be configured in Resend for `resolutionflow.com` domain before production email delivery will work.
---
## Phase 3: Backend Schemas + Endpoints
### 3a. Invite Code Schemas
**Update:** `backend/app/schemas/invite_code.py`
`InviteCodeCreate` — add fields:
- `email: Optional[EmailStr]`
- `assigned_plan: Literal['free', 'pro', 'team'] = 'free'`
- `trial_duration_days: Optional[int]` (validated 190)
`InviteCodeResponse` — add fields:
- `email`, `assigned_plan`, `trial_duration_days`, `email_sent_at`
- Computed flags: `has_trial`, `email_sent`
### 3b. Invite Endpoints
**Update:** `backend/app/api/endpoints/invite.py`
- `POST /invites` — accept new fields (email, assigned_plan, trial_duration_days).
- Create invite with plan/trial/email metadata.
- If email provided, attempt send via EmailService.
- On send success: set `email_sent_at`.
- On send failure: invite still returns 201.
- Add audit log entry for invite creation with delivery result.
- Keep `GET /invites`, `DELETE /invites/{code}`, `GET /invites/validate/{code}` behavior compatible.
### 3c. Registration Plan Assignment
**Update:** `backend/app/api/endpoints/auth.py` (registration endpoint, around lines 178183)
- If invite code is supplied and valid, load it and apply invite plan/trial **regardless of `REQUIRE_INVITE_CODE` setting**.
- For non-account-invite registrations:
- Create subscription with `plan = invite_code.assigned_plan` (fallback `'free'`).
- If `trial_duration_days` is set:
- `status = 'trialing'`
- `current_period_start = now`
- `current_period_end = now + trial_duration_days`
- Else: `status = 'active'`.
- Preserve existing account-invite join flow behavior.
- Mark invite as used after user creation.
### 3d. Admin Subscription + User Detail Endpoints
**Update:** `backend/app/api/endpoints/admin.py`
Enrich `GET /admin/users/{id}` response to include:
- Base user fields (name, email, role, active status).
- Account summary (account name, display code).
- Subscription summary (plan, status, trial end date).
- Recent sessions: latest 10 + total count.
- Recent audit logs: latest 10 + total count.
- Invite code used summary (code, assigned plan, who created it).
Add new endpoints:
- `PUT /admin/users/{id}/subscription/plan` — change user's plan.
- `PUT /admin/users/{id}/subscription/extend-trial` — add days to trial, or convert to trialing if not already.
Both endpoints should create audit log entries.
### 3e. Trial Expiry Check
**Update:** `backend/app/api/deps.py` — in `get_current_active_user`
- Check account subscription status.
- If `status = 'trialing'` and `current_period_end < now`:
- Set `plan = 'free'`, `status = 'active'`.
- Clear/normalize trial period fields.
- Commit before returning user.
**Note:** This is a lightweight login-time check. Users with active JWT sessions will retain access until token refresh. Acceptable for beta; revisit if stricter enforcement needed later.
---
## Phase 4: Backend Schema Additions
**Check first:** Verify whether `backend/app/schemas/subscription.py` already exists. If it does, extend it. If not, create it.
Schemas needed in `backend/app/schemas/subscription.py`:
- `SubscriptionPlanUpdate` — for plan change requests.
- `ExtendTrialRequest` — for trial extension requests.
- `SubscriptionResponse` — for subscription state in responses.
**New file:** `backend/app/schemas/user_detail.py`
- `AccountSummary`
- `SessionSummary`
- `AuditLogSummary`
- `InviteCodeUsedSummary`
- `UserDetailResponse` (superset response for enriched `/admin/users/{id}`)
---
## Phase 5: Frontend Types + API Client
**Update:** `frontend/src/types/admin.ts`
- Enhanced `InviteCodeResponse` with email, plan, trial, email-sent fields.
- New types: `UserDetail`, `SubscriptionDetail`, `SessionSummary`, `AuditLogSummary`, `AccountSummary`.
**Update:** `frontend/src/api/admin.ts`
- Ensure invite endpoints target `/invites` (not `/invite-codes`).
- Enhance `createInviteCode` payload with new fields.
- Add: `getUserDetail(userId)`, `updateUserSubscriptionPlan(userId, plan)`, `extendUserTrial(userId, days)`.
---
## Phase 6: Frontend — Enhanced Invite Codes Page
**Update:** `frontend/src/pages/admin/InviteCodesPage.tsx`
Create form additions:
- Email input (optional, validated).
- Plan selector dropdown (Free / Pro / Team).
- Trial duration input (number of days, shown only when plan ≠ free).
Table additions:
- "Recipient" column (email or "—").
- "Plan" column with badge.
- "Trial" column (days or "—").
- "Email Sent" indicator.
Preserve existing create/copy/delete actions and status badges.
---
## Phase 7: Frontend — User Detail Page
**New file:** `frontend/src/pages/admin/UserDetailPage.tsx`
Sections:
- **Header** — name, email, role badges, active status.
- **Account & Subscription card** — plan, status, trial end date, account display code.
- **Admin Actions card** — Change Role, Change Plan, Extend/Start Trial, Activate/Deactivate (modal-based).
- **Recent Sessions tab** — tree name, started, completed, outcome.
- **Audit Logs tab** — action, resource, timestamp, expandable details.
- **Invite Code card** — code used, plan assigned, who created it.
**Update:** `frontend/src/router.tsx` — add route `admin/users/:userId`.
**Update:** `frontend/src/pages/admin/UsersPage.tsx` — make user rows clickable to navigate to detail page. Ensure action menu clicks (dropdowns, buttons) don't trigger row navigation.

## API / Interface Changes
### Modified Endpoints
- `POST /invites` — new request fields: `email`, `assigned_plan`, `trial_duration_days`.
- `GET /invites` — new response fields: `email`, `assigned_plan`, `trial_duration_days`, `email_sent_at`, `has_trial`, `email_sent`.
- `GET /admin/users/{id}` — enriched response with account/subscription/recent activity details.
### New Endpoints
- `PUT /admin/users/{id}/subscription/plan`
- `PUT /admin/users/{id}/subscription/extend-trial`
---
## Implementation Order
1. Migration 030 (invite code fields)
2. Model update (invite_code.py)
3. Resend integration (email.py, config.py, template, requirements.txt)
4. Backend schemas (invite_code, subscription, user_detail)
5. Backend API (invite.py, auth.py, admin.py, deps.py)
6. Backend tests
7. Frontend types + API client
8. Frontend invite codes page enhancement
9. Frontend user detail page
10. End-to-end testing
---
## Test Plan
### Backend Tests
1. Invite create with `assigned_plan` + `trial_duration_days` persists correctly.
2. Invite create with email — Resend success sets `email_sent_at`.
3. Invite create with email — Resend failure still returns 201, does not set `email_sent_at`.
4. Registration with invite applies correct subscription plan/status/period fields.
5. Registration with optional invite (`REQUIRE_INVITE_CODE=false`) still applies plan/trial when code provided.
6. Expired trial auto-downgrades on authenticated request.
7. Admin plan update endpoint updates subscription + creates audit log.
8. Admin extend-trial endpoint converts/extends correctly + creates audit log.
9. Enriched `GET /admin/users/{id}` returns expected shape and list-size caps (10 sessions, 10 audit logs).
10. Trial duration validation rejects values outside 190 range.
11. Free plan invite rejects trial_duration_days (consistency guard).
### Frontend Verification
1. Create invite with email + plan + trial from admin UI.
2. Confirm invite table renders recipient/plan/trial/email-sent columns.
3. Open user detail from users table (click row).
4. Change plan and extend trial from detail page.
5. Confirm updated values refresh in UI.
6. `cd frontend && npm run build` passes.
### Commands
```
cd backend && pytest --override-ini="addopts="
cd frontend && npm run build
```

## Risks and Mitigations
| Risk | Mitigation |
|------|-----------|
| Endpoint drift (`/invite-codes` vs `/invites`) | Update CLAUDE.md and admin API client. Verify all admin invite calls use `/invites`. |
| Subscription side-effects in auth/deps | Centralize trial-expiry logic. Cover with targeted tests. |
| Payload growth for user detail | Cap related arrays at 10 items, include total counts. |
| Email provider outages | Best-effort send with logging. Invite creation never fails due to email. |
| DNS not configured for Resend | Document as prerequisite. Email gracefully degrades when API key missing. |
| `subscription.py` may already exist | Verify before creating. Extend if present, create if not. |
| JWT session outlives trial expiry | Acceptable for beta. Document as known limitation. |
---
## Rollout
1. Deploy migration and backend changes.
2. Validate admin invite creation and registration path in staging.
3. Deploy frontend with new invite/user-detail UI.
4. Monitor audit logs and invite email delivery behavior post-release.
---
## Assumptions
- Existing admin access control (`require_admin`) remains unchanged.
- Plan limits for `free/pro/team` are already configured in `plan_limits`.
- No mandatory template engine addition is required for email template rendering.
- Alembic `env.py` already imports `InviteCode` model (per LESSONS-LEARNED.md).
