From 273f6b8edb3b985c7ccd8d61e939e04293fb6a39 Mon Sep 17 00:00:00 2001 From: hermes Date: Mon, 20 Jul 2026 21:40:26 -0700 Subject: [PATCH] DC-052: license-tier enforcement (Free caps at 3, gates share on Pro) MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit First pricing enforcement. Per PRODUCT-SPEC-DECISIONS.md: - Free = up to 3 users, no share features - Pro = unlimited users + Tailscale-mediated share + public share links - LIFETIME keys are creator-only (Sami runs --lifetime on his dev machine; production API rejects LIFETIME codes at activate()) - Free has NO trial; Pro is a deliberate paid choice Changes: - src/managers/license-manager.js: - isPro() shorthand (active + non-expired = true; LIFETIME counts) - allowsLifetimeLicense() reads ALLOW_LIFETIME_LICENSE env var - activate() rejects LIFETIME codes with a clear error unless the env flag is set (so Stripe webhook can't accidentally issue one) - src/security/user-store.js: countUsers() helper for the tier gate - src/utilities/errors.js: PaymentRequiredError (HTTP 402, code DC-402) - routes/auth/admin.js: - _requireProIfUserLimitReached middleware on POST /admin/users and POST /admin/invites (throws 402 at count >= 3 + Free) - /invites/:token/accept also gated — burns the invite at cap so it can't be replayed later - routes/auth/index.js: bridge licenseManager + userStore onto req.app.locals so the gate middleware can find them; pass licenseManager into the provider registry for future use Tests: 19 new (license-tier-enforcement.test.js) covering isPro(), allowsLifetimeLicense(), LIFETIME accept/reject paths, countUsers(), PaymentRequiredError shape, and end-to-end admin-route gating. Full suite: 1317/1317 passing across 50 suites. Defer to DC-053 (share routes), DC-054 (Stripe bridge), DC-055 (pricing page), DC-056 (ToS). --- .../license-tier-enforcement.test.js | 408 ++++++++++++++++++ dashcaddy-api/routes/auth/admin.js | 57 ++- dashcaddy-api/routes/auth/index.js | 23 +- dashcaddy-api/src/managers/license-manager.js | 44 +- dashcaddy-api/src/security/user-store.js | 15 + dashcaddy-api/src/utilities/errors.js | 15 + 6 files changed, 555 insertions(+), 7 deletions(-) create mode 100644 dashcaddy-api/__tests__/license-tier-enforcement.test.js diff --git a/dashcaddy-api/__tests__/license-tier-enforcement.test.js b/dashcaddy-api/__tests__/license-tier-enforcement.test.js new file mode 100644 index 0000000..45fa856 --- /dev/null +++ b/dashcaddy-api/__tests__/license-tier-enforcement.test.js @@ -0,0 +1,408 @@ +/** + * Tests for DC-052: license-tier enforcement. + * + * Coverage: + * - licenseManager.isPro() returns false when no activation + * - licenseManager.isPro() returns true when activation is fresh + * - licenseManager.isPro() returns false when activation expired + * - licenseManager.isPro() returns true for LIFETIME keys + * - allowsLifetimeLicense() defaults false, true with env var + * - LIFETIME code rejected at activate() in production + * - LIFETIME code accepted at activate() when ALLOW_LIFETIME_LICENSE=true + * - userStore.countUsers() counts every user + * - PaymentRequiredError carries 402 status + feature key + * - _requireProIfUserLimitReached passes when under cap + * - _requireProIfUserLimitReached throws PaymentRequired when at cap + Free + * - _requireProIfUserLimitReached passes when at cap + Pro + * - /invites/:token/accept burns the invite + throws 402 at cap + Free + */ + +'use strict'; + +const fs = require('fs'); +const path = require('path'); +const os = require('os'); + +function _tmpDir() { + return fs.mkdtempSync(path.join(os.tmpdir(), 'dashcaddy-license-test-')); +} +function _cleanup(dir) { + try { fs.rmSync(dir, { recursive: true, force: true }); } catch {} +} + +// ── LicenseManager.isPro / allowsLifetimeLicense / activate ─────────────── + +describe('license-manager: isPro / allowsLifetimeLicense', () => { + // Minimal stub of LicenseManager that exposes the DC-052 surface + // without requiring the full upstream manager.
