Summary

Implement advanced link controls for the shortener: password protection, scheduling, A/B rotation with weighted variants, and device/geo targeting with priority-based rule evaluation. All features are behind the Professional tier + current.link-controls feature flag, with complete backward compatibility.

Schema additions:

  • urls table: password_hash, active_from, active_until
  • url_variants table: weighted A/B test destinations
  • url_targeting_rules table: device/OS/country-based routing

Core features:

  1. Password protection — bcrypt hashing, constant-time verification, 200 response with password prompt
  2. Schedulingactive_from/active_until window enforcement
  3. A/B rotation — cryptographically-random weighted variant selection
  4. Device/geo targeting — priority-ordered rule matching (device → os → country)

Management API:

  • POST /urls/{id}/password — set password
  • POST /urls/{id}/schedule — set scheduling window
  • GET/POST/PUT/DELETE /urls/{id}/variants — A/B variant CRUD
  • GET/POST/PUT/DELETE /urls/{id}/targeting-rules — device/geo rule CRUD

Preservation:
All existing redirect behaviors preserved:

  • Per-domain routing
  • Rate limiting (1000 req/min)
  • Bot detection
  • GeoIP lookup
  • Expiry checks
  • Click tracking
  • Inactive URL handling

Alembic migration:

  • Revision: b2c3d4e5f6a7 (down_revision: a99a57718815)
  • Tested upgrade/downgrade on SQLite
  • Idempotent on existing deployments

Test plan

  • Alembic migration upgrade/downgrade works on SQLite
  • All new tables created with correct schema
  • Password hashing uses bcrypt (consistent with auth module)
  • Feature flag + tier gating enforced (Professional)
  • Existing redirect tests remain unaffected
  • No syntax errors in implementation
  • Link controls module imports successfully
  • All endpoints properly tenant-scoped

…sk-backend

Resolved two critical issues preventing flask-backend from starting in production:

1. Flask-Principal Compatibility: Disabled Flask-Principal initialization as it
   conflicts with Quart's async context model. Flask-Principal's synchronous
   before_request handlers cause "Working outside of application context" errors.
   The app now runs with JWT-based authentication only.

2. CORS Configuration: Fixed "Cannot allow credentials with wildcard allowed origins"
   error by conditionally disabling credentials when using wildcard CORS origins,
   as required by CORS security specifications.

These fixes enable flask-backend to successfully deploy to Kubernetes and pass
health checks. All pods are now running and healthy in the beta cluster.

The useAuth hook initialized with isLoading=true but checkAuth() was never
called on app mount, causing the app to show "Loading..." indefinitely.

Added useEffect in App.tsx to call checkAuth() on mount, which checks for
existing auth tokens and sets isLoading=false, allowing the app to proceed
to the login page or dashboard.

This fixes the issue where users saw an infinite loading screen at
https://current.penguintech.io

Implements three-tier role-based access control system per CLAUDE.md
and STANDARDS.md requirements:

**Three Organizational Tiers:**
- Global: Organization-wide roles (admin, maintainer, viewer)
- Team: Per-team roles (team_admin, team_maintainer, team_viewer)
- Resource: Per-resource roles (owner, editor, resource_viewer)

**OAuth2-Style Scopes:**
- users:read, users:write, users:admin
- teams:read, teams:write, teams:admin
- urls:read, urls:write, urls:delete, urls:admin
- analytics:read, analytics:admin
- settings:read, settings:write
- system:admin

**Database Schema:**
- scopes: All available permission scopes
- teams: Team/group management
- team_members: Team membership
- role_scopes: Role-to-scope mappings
- user_role_assignments: User roles at specific levels (global/team/resource)
- custom_roles: User-defined roles

**New API Endpoints:**
- GET /api/v1/scopes - List all scopes
- GET /api/v1/roles - List roles with scopes
- POST /api/v1/roles/custom - Create custom role
- DELETE /api/v1/roles/<id> - Delete custom role
- POST /api/v1/users/<id>/roles - Assign role at level
- GET /api/v1/users/<id>/roles - Get role assignments
- GET /api/v1/teams - List teams
- POST /api/v1/teams - Create team
- GET/PUT/DELETE /api/v1/teams/<id> - Team CRUD
- POST/DELETE /api/v1/teams/<id>/members - Manage members

**Permission Enforcement:**
- @require_scope decorator for endpoint protection
- Supports team_id_param and resource_id_param for scoped checks
- Hierarchical permission checking (global → team → resource)

**Files Modified:**
- services/flask-backend/app/rbac.py (NEW): Complete RBAC implementation
- services/flask-backend/app/teams.py (NEW): Team management APIs
- services/flask-backend/app/roles.py (NEW): Role/scope management APIs
- services/flask-backend/app/models.py: RBAC integration
- services/flask-backend/app/__init__.py: Register blueprints
- docs/APP_STANDARDS.md: Full RBAC documentation

This provides enterprise-grade permissions management with custom
role creation and fine-grained access control.

   - Ensures correct file copying during multi-stage build

3. Fixed docker-compose.yml webui context
   - Changed webui context from ./services/webui to . (project root)
   - Matches flask-backend context pattern for consistency

**Testing:**
- Local smoke tests passed with docker-compose
- Flask backend running and healthy
- WebUI building and serving correctly
- All API endpoints requiring authentication properly
- Health checks passing on all services

**Verification:**
- curl http://localhost:5002/healthz - ✅ healthy
- curl http://localhost:3008/healthz - ✅ healthy
- curl http://localhost:3008/ - ✅ serving React app
- curl http://localhost:5002/api/v1/scopes - ✅ requires auth

Ready for Kubernetes deployment.

…startup

Fixes two critical findings:
- C1: JWT_SECRET_KEY no longer falls back to the dev SECRET_KEY default in
  production. ProductionConfig now requires it via env var and validate()
  rejects the dev default, closing an admin-token forgery vector.
- C2: create_app() now calls ProductionConfig.validate() at startup (guarded
  by hasattr so Dev/Testing configs are unaffected), so the dead secret-guard
  actually runs and the app boot-fails on default/missing secrets.

…tokens off URL

Fixes account-takeover and token-leak findings in the OIDC/SSO consumer:
- OC1: callback now validates the id_token (JWKS signature, iss/aud/exp/nonce)
  instead of blindly trusting the userinfo response; identity derives from
  validated claims. Adds PKCE (S256) + nonce to authorize/callback.
- OC2: auto-link/auto-provision gated on email_verified (+ OIDC_AUTO_LINK_
  VERIFIED_EMAIL flag, default off); no more silent email-based account linking.
- OH4: access/refresh tokens returned as httpOnly Secure SameSite cookies, not
  in the redirect URL query string.
- OH5: identity linking only via authenticated OIDC round-trip; removed
  body-supplied external_sub/external_email linking.

Adds nullable columns oidc_providers.issuer, user_oidc_links.email_verified.
_encrypt_secret fail-open and update_provider gating deferred to A5.

Full backend suite: 403 passed, 1 skipped, 90.16% coverage.

…H3/H1)

Closes IDOR: a global viewer holds global tenants:read/teams:read, so the
scope gate passed for everyone and routes then loaded any object by id with
no membership check — any user could read any org's tenants/teams + member
emails across tenants.

- Adds membership helpers in rbac.py; each object-scoped tenant/team route now
  requires the caller to be a global admin OR a member of that specific
  tenant/team (admin ops require tenant/team admin scope, resolved with the id
  so tenant/team-scoped roles are actually consulted).
- create_team validates the body tenant_id against caller membership (no more
  cross-tenant writes).
- Regression tests: non-member viewer 403, member 200, global admin 200,
  foreign-tenant create 403.

Also gitignore /worktrees/ (repo-local worktree convention).

Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>
…follow-up)

The initial isolation fix guarded only read routes; write/admin routes still had
just a global scope gate, so a user with global teams:write/tenants:write (e.g. a
global maintainer) could modify/delete any team/tenant and grant roles across orgs
— privilege escalation. (Also restores object-scoped authz that had regressed when
team_id_param was dropped from the decorators.)

- Adds _is_team_admin / _is_tenant_admin helpers (global admin scope OR team/tenant-
  scoped admin role for THAT object).
- update/delete/add-member/remove-member on both teams.py and tenants.py now require
  the caller to be an admin of that specific team/tenant (or global admin).
- add_team_member/add_tenant_member especially: they grant roles incl. *_admin, so
  non-admins of the object are now blocked.
- Regression tests: global maintainer (no admin role) → 403 on every write route;
  team/tenant admin → 200/201.

Full suite: 423 passed, 90.10% coverage.

…uth introspect/revoke (C3/H3/M4/OM1)

- C3: access tokens now carry a jti; a revoked_access_tokens blocklist is checked in
  auth_required, so /logout and /oauth/revoke actually invalidate the current access
  token (previously only refresh tokens were revoked). Blocklist self-prunes on expiry.
- H3/M4: real rate limiter (app/rate_limiter.py) — Redis-backed when REDIS_ENABLED else
  in-memory, respects RATE_LIMIT_ENABLED. Applied to /auth/login, /auth/register,
  /oauth/token; returns 429 on limit.
- OM1: /oauth/introspect and /oauth/revoke now require authentication; introspect
  returns active:false for revoked tokens or deactivated (is_active=false) users.

Tests: revocation, rate-limit 429, oauth-security + comprehensive rate_limiter tests.
Suite: 441 passed, 1 skipped, 90.82% coverage.

…time, logged errors, safe admin seed (OM4/M1/M2/M3/H2)

- OM4: refresh grant (both /refresh and /oauth/token) now resolves tenant_id + scopes
  like the password grant, so refreshed access tokens keep their tenant/scope claims.
- M1: define rbac + oidc tables (and the former inline create_user table) once at
  startup in init_db, eliminating the request-time check-then-define race on the
  shared DAL across executor threads.
- M2: datetime.utcnow()/utcfromtimestamp() -> timezone-aware datetime.now(timezone.utc)
  in token exp/iat and expiry comparisons.
- M3: replace silent except: pass around tenant/scope resolution and revoke storage
  with logged warnings (no PII/secrets), so degraded-permission failures are visible.
- H2: in production, refuse to seed the default admin with the built-in weak password;
  require DEFAULT_ADMIN_PASSWORD to be set or skip seeding. Dev keeps the convenience
  default with a prominent warning.

Suite: 467 passed, 90.44% coverage.

…des, SSRF-safe URL validation (B1-B2)

Foundation of the open-source URL shortener:
- Schema (models.py + DDL for postgres/mysql/sqlite, defined at startup): urls
  (short_code UNIQUE, tenant/team/collection FKs, expiry, click_count), collections
  (folders via parent_id, unique per tenant+parent), link_clicks (ip_hash only, for
  the redirect task).
- app/urls.py + app/collections.py blueprints under /api/v1, all @auth_required +
  @require_scope + tenant-scoped (tenant derived from token, never body; no cross-tenant
  access; creator-or-tenant-admin for edits).
- Short-code generation via secrets (not random); DB UNIQUE + bounded retry.
- app/urlvalidation.py: scheme allowlist (blocks javascript:/data:/file:), rejects
  literal + resolved private/loopback/link-local/reserved/multicast/metadata IPs
  (IPv4 incl. decimal/hex/octal, IPv6); unresolvable public hostnames allowed (the
  server 301-redirects, never fetches). Reserved-path list for aliases.
- rbac.py: collections:read/write/delete scopes added to role bundles.
- Redirect, click-tracking, analytics, QR, and tier-gating are follow-up tasks
  (TODO hooks left).

Tests: 595 passed, 90.92% coverage — incl. SSRF bypass payloads rejected, alias
collision, tenant isolation, collection nesting/cycle prevention.

Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>
…ics (B3-B4)

- app/redirect.py: public GET /<short_code> → 302 to long_url (404 for unknown/
  inactive/expired), destination re-validated before redirect. Click tracking is
  non-blocking (asyncio.create_task after the response); click_count incremented
  atomically. link_clicks stores ip_hash (salted SHA256, never raw IP) + UA-parsed
  device/browser/os + referer.
- QR: GET /api/v1/urls/<id>/qr (auth + urls:read + tenant-scoped) returns on-demand
  PNG of the short URL (qrcode+Pillow), not stored. TODO(tiering) branded/color QR.
- app/analytics.py: /analytics/urls/<id> (per-link: total, clicks-by-day, top referers)
  and /analytics/summary (tenant-wide totals, top links, time series), analytics:read +
  tenant-scoped. Basic tiers implemented; geo/device/browser breakdowns marked
  TODO(tiering) for the Enterprise advanced-analytics gate.
- deps: qrcode, Pillow, user-agents (pinned+hashed via uv).

Tests: 619 passed, 90.66% coverage — redirect/404/expiry, async click + ip_hash,
QR png, analytics date-filter/pagination/tenant-isolation.

…license (B5)

Two-layer gating (PostHog flag defaulted OFF + license tier), per house tier matrix:
- app/features.py: feature_enabled() (graceful degradation, cached last-known, new
  flags OFF, never crash), get_license_tier() (free/professional/enterprise; dev &
  bypass-domain → enterprise; production fails CLOSED to free on error),
  require_tier/require_professional/require_enterprise decorators → 402 when below.
- Free 5-collection cap enforced server-side in collections.py (402 on 6th; Pro/Ent
  unlimited) — flag current.collections.
- Branded QR (color/logo params) gated to Professional in urls.py QR endpoint (plain
  QR stays Free) — flag current.branded-qr.
- Advanced analytics (geo/device/browser/OS breakdowns) at /analytics/urls/<id>/advanced
  gated to Enterprise; basic analytics stays all-tiers — flag current.advanced-analytics.
- config: POSTHOG_KEY/POSTHOG_HOST (default https://license.penguintech.io).

Tests: 649 passed, 90% coverage; features.py 100% (tier resolution, flag degradation,
each gate 402/allow, mocked posthog+license clients, no network).

- Date filtering (from/to) in advanced analytics
- Advanced breakdown fields (geo, devices, browsers, os)
- Redirect error paths: invalid destination URL validation, user-agent parsing
- Click recording error handling and database exceptions
- Edge cases: no clicks, no user-agent header, database errors with rollback

…r/unique clicks

- Add MaxMind GeoLite2 integration (geoip2 library) for real country/region/city
  geo data with graceful degradation if DB absent
- Implement bot detection via user-agent heuristics; flag is_bot on clicks, exclude
  from click_count + analytics totals
- Apply rate limiting to public redirect endpoint (1000 req/IP/min configurable)
  with fail-open on Redis backend error
- Track unique visitors (distinct by ip_hash) in analytics, returned alongside totals
- Replace hardcoded geo/device/browser/os placeholders in advanced analytics with
  real GROUP BY aggregations over link_clicks; exclude bots from all breakdowns
- Add is_bot boolean column to link_clicks table (migration needed separately)
- Implement PII-safe IP hashing (hash-only, never store raw IP)
- All changes behind PostHog feature flags with graceful degradation

Files added:
- app/geoip.py: GeoIP client wrapper
- app/bot_detection.py: User-agent-based bot detection

Files modified:
- app/redirect.py: Apply rate limiting, bot detection, GeoIP lookup, exclude bots
- app/analytics.py: Real aggregations for geo/device/browser/os, unique visitor counts
- app/models.py: Add is_bot column to link_clicks (both SQLite/MySQL and PostgreSQL)
- app/config.py: Add GEOIP_DB_PATH and RATE_LIMIT_REDIRECT config
- app/__init__.py: Initialize GeoIP client at startup
- requirements.in/txt: Add geoip2 dependency
- tests/test_redirect_analytics.py: Comprehensive coverage for bot filtering, rate
  limiting, geo aggregation, unique visitors, graceful degradation

Test coverage: 46/46 pass. All redis-dependent paths have fallback logic.
Production deployment: Provide GEOIP_DB_PATH to enable geo lookups; if absent,
gracefully continues with country/region/city = None.

… migration

Combines Alembic baseline (schema authority) with redirect-hardening branch
(geoip, bot_detection, rate-limit config, real analytics). Adds is_bot
BOOLEAN column to link_clicks table with dedicated migration.

All 671 tests pass; migrations clean up/down cycle verified.

…ect routing

Implements custom domain registration, DNS TXT verification, and per-domain redirect routing
for multi-tenant support. Domains are tenant-scoped, verified via DNS challenge, and activate
redirect routing to the owning tenant. TLS status tracked for ops integration (cert-manager/ACME).

All domains operations are Free tier, behind feature flag 'current.custom-domains'. Tenant isolation
enforced at database layer. Redirect hardening (rate-limit, bot-filter, GeoIP, validation) preserved.

- Domain model (PyDAL + SQLAlchemy) with unique constraint on (tenant_id, domain_name)
- POST /api/v1/domains — register domain, return DNS TXT challenge
- POST /api/v1/domains/<id>/verify — DNS resolution + verification (dnspython)
- GET /api/v1/domains — list tenant's domains
- DELETE /api/v1/domains/<id> — deactivate domain
- Per-domain routing in redirect.py via _get_tenant_for_domain()
- Alembic migration: a99a57718815 (up/down clean on SQLite)
- 20 comprehensive tests, 75% coverage on domains.py

Change tenant derivation from broken getattr(user, 'tenant_id') [dict accessor]
to g.current_user.get('tenant_id') to match urls.py pattern exactly.

Add tenant_id filter to ALL id-based ops (verify update+reselect, delete):
queries now enforce BOTH id AND tenant_id match, returning 404 when domain
not owned by caller's tenant.

Add regression tests:
- test_tenant_isolation_verify_different_tenant_404: verify cross-tenant attempt
- test_tenant_isolation_delete_different_tenant_404: delete cross-tenant attempt

… gate

Added tests for DNS resolution exception handling, successful DNS record parsing,
and verification success scenarios to reach 90% coverage gate on domains.py.
Domains module now at 86% (improved from 76%), full suite at 90.11%.
Tests now cover exception paths in _resolve_dns_txt_record and verify_domain flows.

…device/geo targeting (Professional)

Implement password protection (bcrypt), scheduling windows (active_from/active_until), A/B rotation with weighted variants, and device/geo targeting rules with priority-based evaluation. All behind feature flag 'current.link-controls' and Professional tier + feature flag gating. Preserve all existing redirect behaviors (rate-limit, bot detection, per-domain routing, expiry, click tracking).

Schema: urls table gains password_hash, active_from, active_until; new tables url_variants (weight-based A/B), url_targeting_rules (device/os/country matching by priority). Alembic migration b2c3d4e5f6a7 with clean up/downgrade.

Management API extends /api/v1/urls with:
- POST /urls/{id}/password — set password
- POST /urls/{id}/schedule — set active window
- GET/POST /urls/{id}/variants — A/B variant CRUD
- GET/POST /urls/{id}/targeting-rules — device/geo rule CRUD

Redirect endpoint integrates link controls:
1. Check password (returns 200 prompt if protected)
2. Check schedule window
3. Resolve destination (targeting rules → variants → long_url)

  - Returns 401 on failure, rate-limited per IP
- SECURITY: Redact full URL from logs, log short_code only (URLs can contain tokens/PII)
- TEST-INFRA: Revert conftest.py alembic subprocess that caused test hang
  - Use raw SQL table creation in app/models.py instead
  - Add url_variants and url_targeting_rules tables to both PostgreSQL and SQLite/MySQL sections
  - Add password_hash, active_from, active_until columns to urls table (all DB types)
  - Clean up test database file at conftest load time for test isolation

Suite now completes in 142 seconds (was hanging before). 689 tests pass.

…ing logic, redirect regressions

## Root Cause
1. Admin user was not being added to default tenant's tenant_members during seeding
   → JWT token had no tenant_id claim
   → Management endpoints couldn't find URLs with tenant_id lookup
2. JWT token parsing wasn't merging tenant_id claim into g.current_user
   → Endpoints read g.current_user.get("tenant_id") and got None
3. Test mocks for rate limiter were patching non-existent module attributes
   → RuntimeError when app context not available in test functions

## Fixes
1. **models.py**: Add admin to default tenant_members on seed (lines 893-901)
   - Ensures admin has tenant_id in JWT token on login
2. **auth.py**: Extract tenant_id from JWT payload and merge into g.current_user (lines 102-105)
   - Now management endpoints can look up URLs by tenant_id correctly
3. **tests/test_link_controls.py**:
   - Fixed rate limiter mock to patch get_rate_limiter() instead of non-existent limiter attribute
   - Fixed app context issues by using app.config.get("db") within app.app_context()
   - Added 5 additional coverage tests for link_controls logic branches

## Test Results
- All 27 link_controls tests now pass (was 16 failures, 6 passes)
- Tests include password protection, scheduling, A/B variants, device/geo targeting
- Added coverage tests for edge cases (missing URLs, wrong passwords, empty variants)

…ocal fix, no global auth change)

Apply _resolve_tenant_id() helper to all 6 new link-controls management endpoints
(password, schedule, variants, targeting rules) to match tenant resolution in existing CRUD
operations. Prevents 404 on token without tenant_id claim by using default tenant fallback.

Comprehensive test coverage for:
- POST /<code>/unlock: password-protected URL unlock with rate limiting,
  password validation, schedule checks, destination revalidation
- /urls/<id>/password: set password with tier/flag gating, validation
- /urls/<id>/schedule: schedule windows with datetime parsing
- /urls/<id>/variants: A/B test variants with CRUD + partial updates
- /urls/<id>/targeting-rules: device/geo/OS targeting with priority
- All error paths: 404 (not found), 400 (invalid), 402 (tier/flag),
  401 (auth), 429 (rate limit)

Coverage: 87.65% → 89.94% (80 new tests, 775 total passing)

Covers schedule-window edges, targeting match types (device/os/country),
empty-lookup fallbacks, and the password-verify error path via a lightweight
fake DAL. Full suite 797 passed, 90.42%.
