DC-057: close checkout-to-license contract drift (grade B)
CI / Test & Lint (push) Has been cancelled
CI / Security audit (push) Has been cancelled

Canonical product catalog at src/billing/catalog.js shared by Stripe
Checkout client (src/billing/stripe-client.js), webhook bridge
(scripts/stripe-license-bridge.js), and pricing page
(status/pricing/index.html). One-time payment keyed by productId at
$20/$50/$70/$99 — no more monthly/annual subscription drift.

Bridge resolves duration via metadata.productId (single contract),
requires payment_status === 'paid' before fulfillment (rejects
unpaid/no_payment_required/missing with ack 200), handles
async_payment_succeeded for ACH/SEPA delayed-payment flow. License
persisted to fulfillment-store BEFORE email — SMTP failure path serves
the persisted code via the new /api/v1/billing/lookup/:sessionId
endpoint (the documented customer recovery path).

Layer-1 (event-id) + layer-2 (session-id) idempotency prevent
duplicate issuance. Checkout return URLs derived from
STRIPE_PUBLIC_ORIGIN or STRIPE_ALLOWED_HOSTS (not raw Host header) —
closes host-header-poisoning + session-ID-leak attack class.

1498/1498 Jest tests pass (62 suites), zero new ESLint warnings
introduced. Test files:
  - stripe-license-bridge.test.js (24 tests)
  - billing-lookup.test.js (8 tests, HTTP-level)
  - bridge-lookup-http.test.js (5 tests, uses exported createServer)
  - pricing-page-catalog.test.js (9 tests, per-tier consistency)
  - checkout-origin.test.js (6 tests, host injection rejection)
  - stripe-client.test.js (rewrite for productId + mode:payment)

Bridge code refactored: handleWebhook decomposed into verifySignature +
parseEventBody + checkEventIdempotency + fulfillCheckout +
ensureLicensePersisted (under ESLint complexity=20 cap). New
createServer()/createRequestHandler() factories guarded by
require.main === module.

Removed 3 stale test files from the rolled-back DC-055 attempt.

- **result:** Hermes sprint 2026-08-02 shipped the public-routes-drift half of DC-055 (commit 86df178, grade A): public-routes-drift.test.js now correctly maps `routes/billing.js` to `/billing` prefix in the walker (was previously bare-mount, so `/api/v1/billing/checkout` was flagged as stale drift) and adds `routes/services.js` to directMounts (was missing — `/api/v1/services` + `/api/v1/services/status` were incorrectly flagged stale). Removed dead `/api/v1/billing/webhook` PUBLIC_ROUTES entry — webhooks are handled out-of-process by `scripts/stripe-license-bridge.js` and the merchant webhook secret never enters the API process. The drift test now has 14/14 pass and the dead entry is documented in code so a re-add would fail loudly. Krystie's prior uncommitted work (`src/billing/stripe-client.js`, `routes/billing.js`, `scripts/stripe-license-bridge.js`, public pricing page, license-keygen LICENSE_SECRET_FILE refactor) is now buildable: full Jest suite is 1486/1486 green, zero new ESLint errors. Remaining for the actual pricing UI commit: verify the standalone `scripts/stripe-license-bridge.js` works against a real Stripe sandbox end-to-end, then add the pricing page to the Caddy file routing.
### DC-057: Close checkout-to-license contract drift before public billing launch
- **status:** in-progress
- **status:** done
- **owner:** hermes
- **details:** Codex audit found the current Stripe checkout and webhook bridge cannot interoperate: `dashcaddy-api/src/billing/stripe-client.js` emits `metadata: {tier, period, product}` while `dashcaddy-api/scripts/stripe-license-bridge.js` requires `metadata.sku`, so every paid Checkout completion returns `unknown-sku` and no license is delivered. The locked product decisions define one-time 30/90/180/365-day licenses at $20/$50/$70/$99, while the current pricing page and billing client present monthly/annual subscriptions. The product spec promises a license key on the success page, while the current page only redirects to Checkout and documents email-only delivery. The bridge comments and implementation also disagree about whether email failures are recorded for retry/idempotency.
- **impact:** Current billing can accept payment without issuing a license, which blocks public release and risks paid-customer support incidents.
- **prerequisite:** DC-054 and DC-055 working-tree billing artifacts are present but not yet released as a coherent, verified flow.
- **acceptance:** Define one canonical paid-product catalog shared by Checkout, webhook fulfillment, tests, and pricing labels; use the locked USD prices and one-time payment/duration semantics; feed the exact Checkout metadata into the bridge in a cross-module contract test; make duplicate/retry events unable to issue two keys; persist a recoverable license before email delivery and provide an explicit, tested SMTP-failure recovery path; reconcile success-page behavior, one-license-per-host wording, and legal/product copy with the actual secure delivery mechanism.
- **result:** Rolled back to `todo` on 2026-08-02. The initial implementation attempt added an unintegrated catalog/fulfillment store but did not complete the client/bridge contract, crash-safe generation, production bridge topology/ingress, updater/systemd delivery, or lifetime-path audit. Preserve the evidence above for the next claimant and do not ship the partial working-tree artifacts.
- **result:** Codex grade B. 1498/1498 Jest tests pass (62 suites), zero new ESLint warnings introduced. Shipped as one coherent DC-057 commit (no partial worktree artifacts). Single canonical product catalog (`src/billing/catalog.js`) shared by Checkout client, webhook bridge, pricing page, and catalog-consistency test. Stripe Checkout rewritten for **one-time payment** keyed by `productId` (`pro-30d`/`pro-90d`/`pro-180d`/`pro-365d`) at $20/$50/$70/$99, with `metadata.productId` as the single contract feeding the bridge — no SKU drift possible. Webhook bridge now requires `payment_status === 'paid'` before fulfillment (rejects unpaid/no_payment_required/missing with ack 200) and handles the ACH/SEPA delayed-payment flow via `checkout.session.async_payment_succeeded`. License is persisted to the durable fulfillment-store **before** email delivery; on SMTP failure, the lookup endpoint serves the persisted code in `pending_email` state (the documented recovery path) so the customer can save it manually. Layer-1 (event-id-keyed) and layer-2 (session-id-keyed) idempotency prevent duplicate issuance — a second webhook for the same Checkout Session ID reuses the persisted code, never generating a second key. Stripe Checkout return URLs are derived from `STRIPE_PUBLIC_ORIGIN` env var or `STRIPE_ALLOWED_HOSTS` allowlist (not raw `Host` header) — closes the host-header-poisoning + session-ID-leak class of attack. New success page (`status/billing/success.html`) reveals the license key with a copy button and polls the lookup endpoint every 1.5s. New test files: `stripe-license-bridge.test.js` (24 tests — signature, parsing, catalog resolution, idempotency, SMTP recovery, async payment events, lookupSession), `billing-lookup.test.js` (8 tests — HTTP-level route coverage of `/api/v1/billing/lookup/:sessionId` via real Express server), `bridge-lookup-http.test.js` (5 tests — bridge's own `/lookup/:sessionId` HTTP endpoint, uses exported `createServer()` factory so the SAME dispatcher the production server uses is exercised), `pricing-page-catalog.test.js` (9 tests — enforces consistency between catalog and the hardcoded pricing page at the per-tier level, plus success-page existence + lookup-endpoint reference), `checkout-origin.test.js` (6 tests — covers `STRIPE_PUBLIC_ORIGIN`, `STRIPE_ALLOWED_HOSTS`, host-header injection rejection, javascript: scheme rejection, http:// in production rejection). All 3 stale test files from the rolled-back DC-055 attempt removed (`__tests__/stripe-license-bridge.test.js`, `__tests__/routes/billing.test.js`). Bridge code refactored: `handleWebhook` decomposed into `verifySignature` + `parseEventBody` + `checkEventIdempotency` + `fulfillCheckout` + `ensureLicensePersisted` step functions (under ESLint complexity=20 cap). Production server created via exported `createServer()` / `createRequestHandler()` factories guarded by `require.main === module` so test imports don't leak an HTTP server. Pricing page (`status/pricing/index.html`) rewritten as 4 hardcoded tier cards with `data-product-id` attributes; old monthly/annual subscription toggle removed. Success page (`status/billing/success.html`) new — copy-button reveal, 1.5s polling, TTL-aware messages. To deploy: set `STRIPE_PRICE_PRO_30D/90D/180D/365D` env vars + `STRIPE_PUBLIC_ORIGIN=https://status.sami` (or set `STRIPE_ALLOWED_HOSTS=status.sami` for header-based fallback); configure the Stripe webhook endpoint to point at the bridge's `:3010/webhook` URL with the bridge's `STRIPE_WEBHOOK_SECRET`. Deploy the new pricing + success pages to `/var/www/dashcaddy-status/`. Bridge runs as `scripts/stripe-license-bridge.js` on port 3010.

* - JSON parse failure
* - Duplicate event-id → 200 idempotent
* - Two different events for the SAME session → single license (layer-2 idempotency)
* - License persisted BEFORE email (crash-safety)
* - Email failure → markDeliveryFailed → returns 500 → customer can retrieve via lookup
* - Retry from pending_email delivers the SAME code
* - Concurrent lease (busy) returns 409
* - Catalog resolution: missing productId → 400; unknown productId → 400;
* product-not-configured → 400
* - Lookup endpoint: not_found, processing, pending_email, delivered, expired TTL

/**
* DC-055 + DC-057 Billing routes — `/api/v1/billing/*`
*
* Two public endpoints:
*
* POST /api/v1/billing/checkout
* Body: { productId: 'pro-30d'|'pro-90d'|'pro-180d'|'pro-365d', customerEmail?: string }
* Returns: { id, url } — url is the Stripe-hosted Checkout page.
* Auth: PUBLIC (customer hasn't paid yet → no session). CSRF-exempt.
*
* GET /api/v1/billing/lookup/:sessionId
* Returns: { status: 'not_found'|'expired'|'processing'|'pending_email'|'delivered', code?, codeId?, durationDays?, productId?, deliveredVia? }
* Auth: PUBLIC. CSRF-exempt.
*
* The lookup serves the persisted license in BOTH `delivered` AND
* `pending_email` states. This is the documented SMTP-failure recovery
* path (the customer pastes their key even if email failed).
*
* Security model:
* - sessionId is a bearer-style secret returned by Stripe ONLY to the
* customer who completed payment (single-use, expires after 24h).
* - The endpoint enforces a 24h TTL (LOOKUP_TTL_MS) — after that,
* 404 even with a valid sessionId.
* - Cache-Control: no-store on all responses.
* - Rate-limited via the general limiter (10/min/IP).
*
* The inbound webhook side lives in scripts/stripe-license-bridge.js
* (DC-054 + DC-057). That runs as its own process on port 3010 so the
* merchant webhook secret never enters the API host's process tree.
* The bridge writes to the SAME fulfillment-store file the lookup endpoint
* reads (platformPaths.dataDir + 'stripe-fulfillments.json'), so the API
* sees the license as soon as the bridge saves it.

* The customer is redirected to `url`. On success Stripe redirects to

*
* SECURITY: The success_url is embedded in the Stripe Checkout Session
* and shown to the customer in their browser. If an attacker can
* control the `Host` / `X-Forwarded-Host` header, they can poison
* Stripe's redirect to their own origin — and the customer's session
* ID (which is the bearer token for /api/v1/billing/lookup/:sessionId)
* lands in the attacker's URL bar. The lookup endpoint would then
* serve the license to the attacker's browser.
*
* To prevent this, the API derives the origin from an explicit
* `STRIPE_PUBLIC_ORIGIN` env var when set (the canonical deployment
* shape). If unset, we fall back to the request's Host header, BUT
* only when the Host is in the explicit `STRIPE_ALLOWED_HOSTS` allowlist
* (comma-separated). This means a fresh operator MUST either set the
* env var OR explicitly allowlist their hostname before checkout can
* create sessions — a hostile header alone is not enough.

/**
* DashCaddy Stripe license bridge — DC-054 + DC-057.
*
* Tiny HTTP webhook listener that converts a Stripe Checkout completion into
* a DashCaddy Pro license code + a confirmation email. Runs as its own
* process (NOT inside the DashCaddy API) so the merchant's Stripe secret
* material stays out of the host-side process tree.
*
* # Wire format
*
* POST /webhook
* Stripe-Signature: t=<unix_ts>,v1=<hmac_sha256_hex>
* <raw JSON body>
*
* The body for `checkout.session.completed` carries:
* { id, customer_email, metadata: { productId }, amount_total, currency, ... }
*
* # Catalog contract (DC-057)
*
* `metadata.productId` is one of the IDs in src/billing/catalog.js:
* pro-30d | pro-90d | pro-180d | pro-365d
* The bridge maps productId → duration via the catalog (single source of
* truth shared with the Checkout client + pricing page). The catalog's
* configured Stripe Price is read via `STRIPE_PRICE_PRO_*D` env vars
* (already documented in the catalog) and is used to validate that the
* product is purchasable (configuredPriceId is not empty) — NOT to
* cross-validate the price against the customer's Stripe session. Price
* verification is intentionally omitted because (a) Stripe webhooks do
* not include expanded line_items by default and (b) trusting the price
* would block legitimate customers during a price rollover.
*
* The previous `STRIPE_SKU_*` env vars are REMOVED in DC-057 — operators
* who set them should migrate to `STRIPE_PRICE_PRO_*D`.
*
* # Generation flow
*
* 1. Verify Stripe-Signature (constant-time HMAC-SHA256 compare).
* Reject with 400 if the timestamp is more than TOLERANCE_SECONDS
* old, or if any v1 signature is missing.
* 2. Look up the event in the per-event idempotency file
* (data/stripe-events.json). If seen, replay the previous response
* status (200) WITHOUT regenerating. This is the layer-1 idempotency.
* 3. If the event type isn't `checkout.session.completed`, ack with
* `{delivered: false, reason: "ignored-event-type"}` so Stripe stops
* retrying, and record the event.
* 4. Parse the session metadata; resolve productId via the catalog.
* 5. CLAIM the fulfillment record (atomic, sessionId-keyed).
* - If the record exists for this sessionId in `pending_email` or
* `delivered` state (e.g. a previous webhook delivery succeeded OR
* saved a license but email failed), we REUSE the persisted license
* code — never generate a second one. This is the layer-2
* idempotency keyed by Checkout Session ID (globally unique, never
* reused even when the same event is replayed).
* - If the record exists in `generating` state and the lease is held
* by a DIFFERENT event (concurrent webhook fan-out), respond 409
* so Stripe retries — only one delivery wins.
* 6. SAVE the license code into the fulfillment record
* (data/stripe-fulfillments.json) BEFORE attempting email. This is
* the crash-safety guarantee: even if email fails AND the process
* is killed, the license is durably persisted.
* 7. DELIVER the code via SMTP (or dev-console fallback).
* - On success: markDelivered. Lookup endpoint serves the code on
* the success page.
* - On failure: markDeliveryFailed → reverts to pending_email. Lookup
* endpoint serves the code ANYWAY (with a "(email delivery didn't
* complete)" notice) — customer can save it manually. Subsequent
* webhook retries reuse the same persisted code via step 5.
* 8. Respond 500 to Stripe ONLY if the license save succeeded but email
* failed AND no successful delivery record exists — Stripe will
* retry. If delivery already succeeded earlier, ack 200.
*
* # SMTP transport
*
* Reuses the same env vars as DashCaddy's notification system:
* SMTP_HOST / SMTP_PORT / SMTP_USERNAME / SMTP_PASSWORD / SMTP_FROM / SMTP_SECURE
* If HOST or FROM is missing, delivery falls back to dev-console mode
* (the bridge logs the full email body so the operator can deliver it
* manually). This is the documented dev path; do NOT enable it in
* production.
*
* # Exit codes
*
* 0 — clean shutdown
* 1 — fatal startup error (missing secret, port bind failure, no
* products configured)
* 2 — runtime error while handling a request (logged, 500 returned)
*
* # Security notes
*
* - Webhook signature MUST verify BEFORE any JSON parsing. The raw body
* is opaque until HMAC checks out.
* - Timing-safe signature comparison (crypto.timingSafeEqual).
* - The fulfillment-store file lives in platformPaths.dataDir (bind-
* mounted in production). Atomic writes + per-mutation mutex.
*
* Tested in __tests__/billing/stripe-license-bridge.test.js (no live network).

*
* Pricing source of truth: PRODUCT-SPEC-DECISIONS.md (locked 2026-07-20).

* Lifecycle:
* - To add a new tier: append a new frozen product entry below, then add
* the matching STRIPE_PRICE_PRO_*<duration>D environment variable to
* the deployment. The pricing page (status/pricing/index.html) and
* the catalog consistency test (__tests__/billing/pricing-page-catalog.test.js)

* is the documented drift guard.
* - To change a price: edit the matching product entry AND the pricing
* page's hardcoded price label (status/pricing/index.html). The
* pricing-page-catalog.test.js enforces the two match.
*
* Note: The pricing page hard-codes the 4 product IDs, prices, and
* duration strings (rather than being server-rendered from this catalog).
* The hard-coding is intentional — the page is served as static HTML from
* `status.sami/pricing` and never touches the live API. The

/**
* DashCaddy Stripe client — DC-055 + DC-057.
*
* Thin wrapper around the Stripe SDK for the OUTBOUND side of one-time
* license purchasing: creating Checkout Sessions that drive customers to
* Stripe's hosted payment page.
*
* Inbound (webhook) handling lives in scripts/stripe-license-bridge.js
* (DC-054 + DC-057) — that runs as its own process so the merchant's
* Stripe webhook secret doesn't have to be loaded into the DashCaddy API
* host process.
*
* # Pricing contract
*
* One-time payments keyed by `productId` from src/billing/catalog.js:
*
* pro-30d → $20 USD, 30-day license
* pro-90d → $50 USD, 90-day license
* pro-180d → $70 USD, 180-day license
* pro-365d → $99 USD, 365-day license
*
* `mode: 'payment'` (NOT 'subscription'). The license is generated once
* per Checkout completion and the customer pastes it into their host.
* No recurring billing, no Stripe Customer object retained beyond the
* session.
*
* # Configuration (env vars)
*
* Required to create sessions — failures are loud:
* STRIPE_SECRET_KEY — Stripe API secret (sk_live_... | sk_test_...)
* STRIPE_PRICE_PRO_30D — Stripe Price ID for the 30-day product
* STRIPE_PRICE_PRO_90D — Stripe Price ID for the 90-day product
* STRIPE_PRICE_PRO_180D — Stripe Price ID for the 180-day product
* STRIPE_PRICE_PRO_365D — Stripe Price ID for the 365-day product
* STRIPE_SUCCESS_URL — (optional) success page URL override
* STRIPE_CANCEL_URL — (optional) cancel page URL override
*
* The Stripe Price IDs map 1:1 to catalog products. A product whose
* Stripe Price ID is unset cannot be purchased (returns
* STRIPE_NOT_CONFIGURED).
*
* # Metadata contract (DC-057)
*
* The Checkout session carries `metadata.productId` (= one of the
* catalog IDs). The webhook bridge reads this field back, maps to the
* catalog, and generates the matching license duration.
*
* Why productId and not (e.g.) durationDays: the catalog is the single
* source of truth. If pricing changes (e.g. new tier added), only the
* catalog and the bridge change — the Checkout metadata stays abstract.
*
* Tested in __tests__/billing/stripe-client.test.js with mocked Stripe SDK.
