From 524976e20f58ac867f0161194635ce085affe084 Mon Sep 17 00:00:00 2001 From: Justin Bowen Date: Mon, 13 Jul 2026 23:16:05 -0500 Subject: [PATCH 1/2] feat(shortener): Free/Pro/Enterprise tier gating via feature flags + license (B5) MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit 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//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).
