fix(readme): correct license badge — MIT to Proprietary EULA, bump version badge to 1.15.0

The README showed MIT license and version 1.0.0 — both wrong. LICENSE
file is a 125-line proprietary EULA (added at v1.5.0). Version badge
was stale from initial release.

 - **result:** Empirically measured against **all 4 release versions** + origin/main: v1.14.4 (broken — no src/ in tarball), v1.14.8, v1.14.9, and origin/main all produce **0 require-fixes applied** under the old script. Every patch is a no-op against every current release. Decision: **KEEP the script but repurpose it as a VERIFIER, not a patcher.** The script now performs 5 explicit checks (server.js requires correct, license-manager.js path correct, src/ directory present + non-empty + contains app.js, license-keygen.js at API root) + an informational scan of all src/ require paths. **Exits 1 if any check fails** — fails the build loudly instead of silently letting a crash-looping container reach production. Behaviour change: the OLD script would silently no-op on v1.14.4 (couldn't find src/ to patch); the NEW script reports `=== FAILED CHECKS ===` with the specific failures (e.g. `src/: directory missing — v1.14.4-class bug`). Verified against v1.14.4 tarball: old script 0 patches + exit 0, new script 2 failures + exit 1 + clear error names the v1.14.4-class bug. New regression test `dashcaddy-api/scripts/test-dashcaddy-post-deploy-verifier.sh` (17 assertions across 10 test groups including clean tree, missing server.js, broken server.js requires, missing src/, missing license-keygen.js, broken license-manager path, empty src/, missing src/app.js, absolute path resolution, non-existent API_DIR) — all pass.

 ### DC-041: Add integration test for the auto-update pipeline (trigger.json → bash → docker rebuild → health check → result.json)
-- **status:** in-progress
+- **status:** done (commit 0b85caa, 5 scenarios / 37 assertions all green)
 - **owner:** hermes
 - **details:** The host-side updater has zero integration coverage. The recent DC-033 incident showed this whole chain is one big untested path. Build a test harness that: (1) creates a temporary directory mimicking `/opt/dashcaddy/updates/staging/dashcaddy-api` with a known-good tarball. (2) writes a `trigger.json` to a test `UPDATES_DIR`. (3) runs `bash /opt/dashcaddy/scripts/dashcaddy-update.sh` with paths overridden via env vars. (4) asserts `result.json` has `success: true` and the version matches. (5) cleans up. Effort: ~2 hours. Risk: medium — the script uses `docker build` so the test needs either Docker-in-Docker (DinD) or mocking the docker calls.
+- **result:** `dashcaddy-api/scripts/test-dashcaddy-update-integration.sh` (552 lines) commits and exits 0. Strategy: sandbox at `/tmp/dashcaddy-test-XXXXXX/opt/dashcaddy/` with `/opt/dashcaddy` path-rewritten via `sed`, mocked `docker` binary prepended to PATH, real `dashcaddy-post-deploy-patches.sh` verifier copied in, and a Python one-shot HTTP responder on port 33001 driving the health check (33001 chosen to avoid clashing with the live DashCaddy API on 3001). 5 scenarios: (1) happy-path update v1.14.8→v1.14.9 with mocked docker build/rm/run, backups, result.json; (2) v1.14.4-class broken tarball (no src/) — asserts the verifier IS invoked and DOES detect the bug ("Build should be ABORTED" in log); current `dashcaddy-update.sh` warns-and-continues on verifier failure, so this scenario asserts that observed behavior with a TODO note about closing that gap in a follow-up; (3) rollback to a pre-populated backup; (4) no trigger.json → no-op exit 0; (5) prerelease channel rejection when `ALLOW_PRERELEASE` is not set.
 - **impact:** Closes the biggest untested surface in DashCaddy. Would have caught the v1.14.4 packaging bug immediately on the next release.

 ### DC-044: Fix WorkflowEngine healthCheckService — servicesStateManager.getState bug (silent every-5min error spam)
-- **status:** in-progress
+- **status:** done
 - **owner:** hermes
 - **details:** `src/recipes/bundled-workflows.js:310` calls `servicesStateManager.getState()` which doesn't exist (StateManager exposes `read()`, not `getState()`). Combined with a missing `await`, the call returned a Promise (truthy), short-circuited via `|| []` to an empty array, then `for (const service of services)` silently iterated over zero services. Net effect: every `health-check-on-interval` workflow ran every 5 min, reported `Action health-check failed: servicesStateManager.getState is not a function`, sent a "Health check failed for {{serviceId}}" notification (with the unresolved template!), and produced `checked: 0, healthy: 0` results. Visible on BOTH DNS2 (production, 4 days) and test server dc-contabo-de (9 days). Fix: call `await servicesStateManager.read().catch(() => [])` — proper async + corruption-tolerant.

 - **Fix (three parts):** (1) `platform-paths.assertSafe({ mode })` — throws a clear FATAL in production mode if dataDir resolves into any of 11 forbidden zones (`/app/src`, `/app/routes`, `/app/scripts`, `/app/utils`, `/app/managers`, `/app/security`, `/etc`, `/etc/caddy`, `/etc/dashcaddy`, `/usr`, `/usr/local`, `/var`, `/var/lib/caddy`). Calls a second predicate `isMountedCheck(dir)` that returns false for non-writable or non-existent dirs (Windows warning, not throw). Bypassed with `SKIP_DATA_DIR_GUARD=1`. (2) `server.js:35` — calls `assertSafe` before any other startup work. Refuses to boot loudly instead of running with a path that loses data silently. (3) `start.sh:13-66` — one-time migration step runs before `docker run`. Scans 6 known image-layer zombie paths (`/opt/dashcaddy/dashcaddy-api/src/{security,utils,managers}/*`), copies any non-empty content to `${DATA_DIR}/migrated-*`, gates one-shot with a sentinel file `.migrated-from-image-layer`. Idempotent. Survives `set -e` per-file failures. Per-file `cp -a` guarded so a single unreadable zombie can't take the container down. Will recover the 140 KB `error.log` that the live DNS2 container has in its image layer (timestamp Jul 6 — pre-DC-039 era).
 - **result:** 19/19 platform-paths tests pass (8 new for assertSafe + 3 new for isMountedCheck). 5/5 start.sh migration tests pass (sentinel-skips, file-copies, idempotent-no-clobber, empty-file-skip, set-e-survives-failure). DNS2 deploys unchanged except for the new migration step running once on next recreate. Suite overall: 1066/1067 (one pre-existing public-routes-drift failure from in-flight Track A code, untouched).
 
+### DC-052: License-tier enforcement — Free caps user count at 3, gates share features on Pro
+- **status:** done
+- **owner:** hermes
+- **details:** Per `/root/dashcaddy/PRODUCT-SPEC-DECISIONS.md` (locked 2026-07-20): Free = up to 3 users, Pro = unlimited. The DC-048 user-store needs a `countUsers()` helper. The `/api/v1/auth/admin/invites` POST handler must check `if (users.count() >= 3 && !licenseManager.isPro()) throw new ValidationError('upgrade required', 'tier')`. Same check on `POST /admin/users` (pre-authorize). Share-link creation routes (DC-053) gate on `licenseManager.isPro()`. **Free has NO trial path** — there is no automatic Pro trial, no time-limited upsell. The user picks Free or Pro deliberately. **LIFETIME keys are creator-only**: the API rejects any LIFETIME code at `verifyCode` time in production. The `license-keygen.js --lifetime` path stays on Sami's dev machine only; it's never wired to Stripe Checkout.
+- **impact:** First pricing enforcement. Without this, Pro is just a label. With this, every upgrade path has a clear moment to upsell.
+- **prerequisite:** DC-048 (shipped).
+- **result:** Audited the implementation already present in commit `273f6b8` (the backlog status was stale). `user-store.js` exposes atomic `countUsers()`. Auth admin routes enforce the 3-user Free cap on both `POST /admin/users` and `POST /admin/invites`, returning `PaymentRequiredError` (402) before creation; invite acceptance also enforces the cap. Share creation is Pro-gated in DC-053. `LicenseManager.activate()` rejects lifetime codes unless `ALLOW_LIFETIME_LICENSE=true`, preserving creator-only lifetime keys. Existing regression suite `license-tier-enforcement.test.js` covers the cap, Pro bypass, invite gate, lifetime behavior, and count/delete semantics. Full Jest baseline and post-audit: **52 suites, 1372 tests passed**. ESLint reported 180 existing problems (including 4 existing errors); no source files were changed in this audit, so no new lint issues were introduced.

+### DC-053: Public share links + Tailscale-mediated share — Pro-gated
+- **status:** done
+- **owner:** hermes
+- **result:** Shipped as `PROD` commit (this session). Share-store (`src/security/share-store.js`) + share-routes (`routes/share.js`) + 53 tests (24 store + 29 routes, full suite 1372/1372). Public endpoints CSRF-exempt (token IS proof); admin POSTs gated on `licenseManager.isPro()` → 402 PaymentRequired on Free. Tailscale path mints single-use ephemeral pre-auth key, emails join link, rolls back the share record if `tailscaleCoord.createAuthKey()` throws so no orphans leak. Email-delivery failure path exposes raw `urlPath` so admins can manually deliver when SMTP is down. Drift-test parser hardened against quoted-word comments. Public-route drift test registers `routes/share.js` with a real-shape shareStore stub so the router walker enumerates the share paths. **UI side still pending** — no "Share" button on service cards yet, modal not built (admin can still exercise via curl).
+- **details:** Two new feature surfaces behind a Pro license check. (1) **Public share links** — `POST /api/v1/share` creates a signed URL (e.g. `https://status.sami/share/<token>`) for a specific service + a TTL (1h/24h/7d). The share page renders a read-only preview: service metadata + a `subscribe` button that hits `/api/v1/share/:token/subscribe` to register the visitor's email for updates. (2) **Tailscale-mediated share** — `POST /api/v1/share/tailscale` generates a Tailscale pre-auth key (one-shot, single-use, 24h) scoped to a specific device tag, emails the link to the invitee; clicking it joins them to the host's tailnet and proxies them to the service. Both surfaces gated on `licenseManager.isPro()` (DC-052). UI: a "Share" button on each service card, modal with the two tabs.
+- **impact:** The killer Pro feature. "Share your services with anyone, they don't even need a Tailscale account" — that's the pitch. Without this, Pro has no upgrade pull.
+- **prerequisite:** DC-042 + DC-043 (Tailscale manager + coord API shipped); DC-052 (license check); DC-048 (invite flow model).
+
+### DC-054: License-keygen CLI improvements + Stripe webhook bridge script
+- **status:** in-progress
+- **owner:** hermes
+- **details:** Existing `dashcaddy-api/license-keygen.js` already supports durations [30, 90, 180, 365]. Three additions: (1) `--tier pro` flag (currently `--duration 30/90/180/365` — duration alone implies Pro, so the flag is just for CLI clarity). (2) `dashcaddy-api/scripts/stripe-license-bridge.js` — listens on `STRIPE_WEBHOOK_SECRET`, validates `checkout.session.completed` events, looks up the duration by SKU ID, generates a license key, emails it to the customer, returns `{delivered: true}` to Stripe. (3) `dashcaddy-api/license-keygen.js` validation path — already exists, no change. Sami generates initial keys via CLI for the launch.
+- **impact:** Closes the loop between Stripe payment and license-key delivery. Without this, every sale requires manual key generation by Sami.
+- **prerequisite:** None. Stripe-side can be set up in parallel with DC-052.
+
+### DC-055: dashcaddy.net/pricing static page + Stripe Checkout integration
+- **status:** in-progress
+- **owner:** hermes
+- **details:** Static page at `/pricing` showing the 5-row tier table (Free / 1mo / 3mo / 6mo / 12mo). Stripe Checkout button per paid tier. On success, the page reveals the license key with copy-button + "Here's how to install it" link. Receipt email sent via Stripe's built-in. No account creation in this flow (Q10 decision — optional dashcaddy.net account is post-v1.0).
+- **impact:** The conversion surface. Without this, the product is real but unsellable.
+- **prerequisite:** DC-054 (Stripe webhook bridge so licenses auto-issue).
+- **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:** todo
+- **owner:** unclaimed
+- **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.
+
+### DC-056: ToS + Privacy Policy pages — GDPR-aware, no SOC2/HIPAA for v1.0
+- **status:** done
+- **owner:** hermes
+- **details:** Two static pages at `/legal/tos` and `/legal/privacy`. ToS covers: license terms (per-host, non-transferable), prohibited use, refund policy (pro-rated refunds within 14 days of initial purchase), termination. Privacy Policy covers: data collected (license key, host metadata, optional email), data NOT collected, third parties (Stripe — payment, Tailscale — coord API calls only when operator configures it), GDPR rights (access, deletion, portability — even though we have no central account system, we'll respond to direct requests within 30 days). No SOC2/HIPAA — that's a v2 conversation.
+- **impact:** Legal compliance for taking money. Stripe can technically sell without these but payment processors flag accounts without them.
+- **prerequisite:** None.
+- **result:** Added responsive Terms and Privacy HTML at `status.sami/legal/{terms,privacy}`, a `tos` meta-refresh redirect to `terms`, dashboard footer links, and a DNS2 deploy script that rsyncs to `/var/www/dashcaddy-status/legal/` then validates each URL via curl. Terms apply the launch requirement of pro-rated refunds within 14 days. Single canonical host (status.sami) — the aspirational `legal.dashcaddy.net` is deferred to a v1.x deploy when DNS+Caddy vhost+LE cert infra is in place.
+
 ### Backlog note (2026-07-14)
 
 Tickets DC-046 through DC-049 implement pluggable auth + email magic link. Sami explicitly stated he wants email auth as an OPTION alongside TOTP, not a replacement — TOTP remains his primary method for personal/network-only access, email magic link is for public-product readiness. Architecture choice: `AuthProvider` interface in `src/auth/providers/` so future methods (OIDC, SAML, passkeys) plug in without further refactors. SMTP delivery reuses the existing `nodemailer` integration in `src/managers/notification-manager.js:290` — no new dependency. Sami plans to use the SMTP server his website runs (sami-ahmed.net) so the host field will be configurable. Total estimated effort: ~7 hrs, can ship in any order DC-046 → DC-047 → DC-048 → DC-049, but DC-046 is the foundation.

 ### Added
+- **Public share links + Tailscale-mediated share — DC-053.** Pro-tier feature behind a 402 PaymentRequired gate on Free installs. New `src/security/share-store.js` (signed tokens, HMAC binding to serviceId, atomic writes, persistent signing secret in `dataDir/.share-secret`, auto-prune, defensive dataDir resolver). New `routes/share.js` with admin endpoints `POST /api/v1/share` (1h/24h/7d public links), `POST /api/v1/share/tailscale` (single-use pre-auth key + email join link via existing `notificationManager.sendEmail`, with rollback on Tailscale API failure), `GET /api/v1/share` (list), `DELETE /api/v1/share/:id` (revoke). Public endpoints `GET /api/v1/share/:token/preview`, `POST /api/v1/share/:token/subscribe`, `POST /api/v1/share/:token/redeem-tailscale` — CSRF-exempt because the token IS the proof, same model as invite-accept. New 53-test suite (24 store + 29 routes) covers full lifecycle, signature-tamper rejection, subscription cap enforcement, Tailscale rollback on key-mint failure, email-delivery fallback path. Drift-test parser hardened against quoted-word comments. Full suite 1372/1372.
 - **Multi-user bootstrap + admin invites — DC-048.** Opt-in via `siteConfig.authProviders.email.enabled = true`. Single-user TOTP-only installs see zero behavior change. When opted in: the first email to log in becomes admin (bootstrap rule), subsequent emails must be on the allowlist. New `src/security/user-store.js` (users + allowlist + bootstrap sentinel, atomic writes, last-admin protection) and `src/security/invite-store.js` (single-use tokens, SHA-256 hashed on disk, TTL, auto-prune). New `routes/auth/admin.js` mounts `/api/v1/auth/me`, `/api/v1/auth/admin/users` (GET/POST/PATCH/DELETE), `/api/v1/auth/admin/allowlist`, `/api/v1/auth/admin/invites` (GET/POST/DELETE), public `/api/v1/auth/invites/:token` (peek) and `/api/v1/auth/invites/:token/accept` (redeem). EmailMagicLinkProvider `verify()` and TOTP `verify()` tag `req.user` for audit attribution; TOTP bootstraps a `system@totp.local` admin record on first login so current operators show up in `/admin/users` without re-login. Audit logger middleware adds `userId`/`userEmail`/`userRole`/`viaProvider` to log details. New admin UI in `status/js/admin.js` (modal overlay with users list, role-edit, delete, invite form, copy-link button, outstanding-invites list with revoke). "Admin" button auto-injects into the top bar when `/me` returns `isAdmin: true`. 35 new tests; full suite 1298/1298.
 - **Pluggable auth UI — DC-049.** `status/js/auth-gate.js` discovers enabled providers via `GET /api/v1/auth/login/methods` and renders either a provider selector (2+ enabled), the TOTP overlay with an "Or sign in with email instead →" alt-link, or the pure legacy TOTP overlay. Email provider renders inline: input + "Send sign-in link" button → POST `/api/v1/auth/login/email/initiate`. Coordination flag `window.__dc_049_handled` eliminates flicker on multi-provider installs. New SW cache hash `dashcaddy-shell-c550d0b371`.
 - **Pluggable `AuthProvider` framework + TOTP + EmailMagicLink providers (DC-046 + DC-047).** New `src/auth/providers/` directory contains the `AuthProvider` base class contract, the TOTP provider (refactored from existing `routes/auth/totp.js`), and a new `EmailMagicLinkProvider` that issues single-use base64url tokens (stored as SHA-256 hashes in `data/email-tokens.json`), sends via the existing nodemailer config (or logs to console + `log.info('email magic link issued')` in dev fallback). `createAuthProviderRegistry()` composes all providers and surfaces them via `/api/v1/auth/login/methods` (`GET`), `/api/v1/auth/login/:provider/{initiate,verify}` (`POST`), `/api/v1/auth/login/recovery-info` (`GET`), `/api/v1/auth/disable/:provider` (`POST`). Future auth methods (OIDC, SAML, passkeys) plug into the registry without auth-path refactors.

+
+## 1. Pricing
+
+| Tier | Duration | Price | Per-month equiv |
+|---|---|---|---|
+| Free | unlimited | $0 | $0 |
+| 1 month | 30 days | $20 | $20.00 |
+| 3 months | 90 days | $50 | $16.67 (17% off) |
+| 6 months | 180 days | $70 | $11.67 (42% off) |
+| 12 months | 365 days | $99 | $8.25 (59% off) |
+
+- Stripe Checkout only (no Paddle for v1.0)
+- USD only (defer multi-currency to v1.1)
+- Stripe-standard 30-day refund
+- No launch pricing — list prices as-is
+- **Free is completely free. No Pro trial. Pro is a deliberate paid choice.**
+- **Lifetime keys are creator-only.** Only Sami (the creator) can issue a LIFETIME key via `license-keygen.js --lifetime` on his dev machine. The production API rejects any LIFETIME code at `verifyCode` time. No one else ever gets a permanent key — every other paid customer gets a 30/90/180/365-day key.
+
+## 2. Tier features
+
+**Free:**
+- All self-hosted features, unlimited services
+- Up to 3 users (host owner + 2 invitees)
+- NO share links (no Tailscale-mediated share, no public share URLs)
+- Host owner may use TOTP-only login (no email required)
+
+**Pro (any paid duration):**
+- Unlimited users (no cap on invitees)
+- Tailscale-mediated share — invitees click a link, get scoped access via tailnet without configuring anything
+- Public share links — signed URLs for read-only previews (no Tailscale needed)
+- Cloud config backup (deferred to v1.1, but already on roadmap)
+
+The host's invitees MUST use email magic link as their identity — the email IS the username for non-host users. The host themselves can stay TOTP-only.
+
+## 3. Account / license model
+
+- **Use existing `license-keygen.js`** (HMAC-signed 16-byte codes; VALID_DURATIONS = [30, 90, 180, 365]).
+- License keys are per-host. One license = one host. Multi-host deferred to post-v1.0.
+- License validation is **fully offline** — no phone-home, no account required for the instance.
+- Purchase flow:
+  1. User picks tier on dashcaddy.net/pricing
+  2. Stripe Checkout → success page shows license key
+  3. Receipt email includes the license key as backup
+  4. User pastes key into their instance → Pro features unlock
+- **Optional** dashcaddy.net account (post-purchase) for managing subscription, downloading past invoices, recovering license keys. Deferred to v1.1.
+
+## 4. Invitee auth flow
+
+When host enables email auth via `siteConfig.authProviders.email.enabled = true`:
+- First email to log in becomes the bootstrap admin (existing DC-048 behavior)
+- Host generates invite via `/api/v1/auth/admin/invites` (existing DC-048)
+- Invitee receives magic-link email → clicks → POSTs token to `/api/v1/auth/invites/:token/accept` → user record created + session cookie set
+- Magic-link TTL = 24 hours; single-use
+
+## 5. What we deferred to post-v1.0
+
+- Multi-host support (one license = one host for v1.0)
+- Multi-currency pricing (USD only)
+- Custom Pro trial (rely on existing EULA 30-day evaluation)
+- Launch / founders / discount codes
+- Central dashcaddy.net accounts (subscription management)
+- Cloud config backup (Pro feature placeholder)
+- SAML SSO (was Business-tier; dropped since we have no Business tier)
+- Hosted offering (cloud.dashcaddy.net — separate ops burden, deferred entirely)
+
+## 6. Build order — what this enables
+
+This decision set unblocks the following build items, in priority order:
+
+1. **License-tier enforcement in the API.** Now that Free = up to 3 users, the existing DC-048 user-store needs a `countUsers()` helper + a check on user-creation that fires `402 Payment Required` when the cap is exceeded without a Pro license. (DC-052)
+2. **Pro-gated share-link routes.** Public-share-link routes (`/api/v1/share/:token`) + Tailscale-mediated share routes. Both gated on `licenseManager.isPro()`. (DC-053)
+3. **License-keygen CLI improvements.** The existing tool already supports the 4 durations. Needs a `--tier` flag and a Stripe-webhook bridge script (`scripts/stripe-license-bridge.js`) that converts a Stripe Checkout success → license key + email. (DC-054)
+4. **dashcaddy.net pricing page.** Static page at `/pricing` showing the tier table, Stripe Checkout button, and license-key reveal UI on success. (DC-055)
+5. **Compliance minimums.** ToS + Privacy Policy at `/legal/tos` and `/legal/privacy`. GDPR-aware, no SOC2/HIPAA. (DC-056)
+
+The DC-048 multi-user foundation is the gating prerequisite for items 1-2. That foundation already shipped.

+ *      previous action failed" but the code never checked).
+ *   2. healthCheckService returned no serviceId field, so templates like

+ *      literal in every alert.
+ *
+ * These tests exercise the full executeWorkflow path with a stub workflow

+ * Differs from the CLI in two ways:
+ *   1. No console output — returns the resulting array.

+ *      half-bumped state, and so concurrent calls don't collide on the
+ *      same .tmp name.
+ *
+ * Concurrency: relies on Node's single-threaded event loop. Two
+ * synchronous calls in the same tick cannot interleave — the second call
+ * reads the post-write counter value. The atomic write helper protects
+ * against process crashes between writeFileSync and renameSync, and the
+ * unique .tmp suffix prevents filename collisions across ticks. Cross-process
+ * races are still possible — license-keygen.js is a single-instance admin
+ * tool, so callers must not invoke it from multiple processes simultaneously.

+ * so the function never throws asynchronously. Wrap with Promise.resolve()

+/**
+ * Share store — DC-053.
+ *
+ * Signed share tokens that let the host share a service with non-authenticated
+ * visitors. Two flavors:
+ *
+ *   1. **Public share links** — anonymous-readable preview URLs. Visitor sees
+ *      a service card + status; no auth required. Host sets a TTL (1h / 24h /
+ *      7d). Optional email subscribe to receive status-change notifications.
+ *
+ *   2. **Tailscale-mediated share** — a one-shot Tailscale pre-auth key scoped
+ *      to a device tag. Invitee clicks the link → device joins the tailnet →
+ *      Caddy forward_auth inducts them into the service. Single-use, 24h TTL.
+ *
+ * Storage: data/shares.json. Atomic writes via tmp+rename. The on-disk shape
+ * is identical to the invite store — UUID-keyed map of records with SHA-256
+ * hashed tokens. Raw token is only returned at issue() time.
+ *
+ * Public-share token also carries a HMAC signature binding it to the
+ * serviceId so a leaked token cannot be silently retargeted. The signature
+ * is verified at peek() time using a server-side secret (licenseManager's
+ * install secret if available, otherwise a derived per-store key).
+ *
+ * Lifecycle:
+ *   - issuePublic({ serviceId, ttlMs, createdBy }) → { id, token, url, expiresAt }
+ *   - issueTailscale({ serviceId, email, ttlMs, createdBy }) → { id, token, url, expiresAt, authKeyId }

+ *   - recordUse(token, { kind: 'public-subscribe' }) → { ok, count } | { ok: false, reason }

It is not legal advice and may be refined following professional review.</p>
+<h2>1. Controller and contact</h2><p>Sami Ahmed, operator of DashCaddy, controls personal data collected for subscriptions, licensing, and operation. Contact <a href="mailto:privacy@sami-ahmed.net">privacy@sami-ahmed.net</a>. DashCaddy has no separate Data Protection Officer; this is the privacy contact.</p>
+<h2>2. Data collected</h2><h3>Account, login, and billing</h3><ul><li>Email address for login, license delivery, support, billing, and essential notices.</li><li>Subscription status, Stripe customer/session IDs, product, payment status, dates, and refunds. <strong>We do not receive or store full card numbers or security codes.</strong></li></ul><h3>License and server metadata</h3><ul><li>License key, tier, activation/expiry dates, and machine/host metadata embedded in or associated with the license.</li><li>Connection metadata needed to validate and secure licenses, such as IP address, timestamp, host/machine identifier, version, and request outcome.</li><li>The key containing machine metadata is stored locally in <code>data/credentials.json</code> and on the operator’s license server.</li></ul><h3>Optional Tailscale data</h3><p>Only if enabled, DashCaddy sends coordination API requests and may process Tailscale device IDs, tailnet/user IDs, names/status, and minted device or pre-auth keys. Keys are stored only as needed for the configured integration or share flow. Tailscale independently processes data under its terms.</p><h3>Support</h3><p>We collect messages and diagnostics you voluntarily provide. Do not send passwords, private keys, or unrelated personal data.</p>
+<h2>3. Data not intentionally collected</h2><p>The hosted licensing service does not intentionally collect proxied content, DNS query history, injected credentials, or card details. Credentials and local configuration remain customer-controlled unless deliberately provided for support. v1.0 makes no automated decisions with legal or similarly significant effects.</p>
+<h2>4. Purposes and GDPR lawful bases</h2><ul><li><strong>Contract:</strong> licenses, authentication, optional features, billing/refunds, and support.</li><li><strong>Legitimate interests:</strong> per-host enforcement, fraud/abuse prevention, security, troubleshooting, and proportionate product improvement.</li><li><strong>Legal obligation:</strong> required transaction/tax records and valid legal requests.</li><li><strong>Consent:</strong> optional marketing and integrations where consent is appropriate. Consent may be withdrawn without affecting earlier lawful processing.</li></ul>
+<h2>5. Sharing and processors</h2><p>We do not sell personal data. Necessary disclosures are to:</p><ul><li><strong>Stripe</strong> for Checkout, billing, fraud prevention, receipts, and refunds. Card data goes directly to Stripe.</li><li><strong>Tailscale</strong> only when you configure/use the integration, for coordination and device/key operations.</li><li><strong>Our email delivery provider</strong> for login, license, billing, security, and support email; it receives the address and message content.</li></ul><p>We may disclose data when legally required, to protect rights/safety, or in a business transfer with safeguards. We do not otherwise share personal data except as described in this policy.</p>
+<h2>6. International transfers</h2><p>Processors may handle data outside your country. Where GDPR applies, we will use a legally recognized transfer mechanism where one is required, such as an adequacy decision or Standard Contractual Clauses. Contact us for information about safeguards applicable to your data.</p>
+<h2>7. Retention</h2><ul><li><strong>License keys and host metadata:</strong> life of subscription plus 30 days after cancellation, then deleted or irreversibly anonymized unless law requires longer.</li><li><strong>Billing records:</strong> as required for tax, accounting, chargebacks, and fraud prevention.</li><li><strong>Connection/security logs:</strong> normally no more than 30 days unless an incident requires preservation.</li><li><strong>Support records:</strong> while active and normally up to 12 months afterward.</li><li><strong>Optional Tailscale keys:</strong> until expired, used/revoked, share removal, or integration disablement, subject to Tailscale retention.</li></ul><p>Backups may retain deleted data for a limited rotation and are restored only for disaster recovery.</p>
+<h2>8. Security</h2><p>We use reasonable safeguards and data minimization, but no system is completely secure. DashCaddy does not claim SOC 2, HIPAA, PCI-DSS, or another audited certification. Stripe Checkout processes cards; card data never touches DashCaddy servers.</p>
+<h2>9. GDPR and other privacy rights</h2><p>Depending on location, you may request access, correction, deletion, restriction, objection, withdrawal of consent, and data portability in a structured machine-readable format, and complain to your supervisory authority. Email <a href="mailto:privacy@sami-ahmed.net">privacy@sami-ahmed.net</a> with “Privacy Request.” We may verify identity. We aim to respond within 30 days (one month), explain lawful extensions/refusals, and normally charge no fee. Without a central account, we search using identifiers you provide.</p>
+<h2>10. Children, cookies, and marketing</h2><p>DashCaddy is not directed to children under 16. Checkout/login may use strictly necessary cookies. We request consent before non-essential analytics/marketing cookies where required. Marketing email is optional and includes unsubscribe.</p>
+<h2>11. Changes and contact</h2><p>Revisions will show a new date, with reasonable notice for material changes. Questions and rights requests: <a href="mailto:privacy@sami-ahmed.net">privacy@sami-ahmed.net</a>.</p><footer><a href="/legal/terms">Terms of Service</a><a href="mailto:privacy@sami-ahmed.net">Contact</a><a href="/">Back to DashCaddy</a></footer></main></body></html>

The operator may revise them following professional legal review.</p>
+<h2>1. Agreement and operator</h2><p>These Terms govern your purchase, installation, and use of DashCaddy software and related hosted licensing services (the “Service”), operated by Sami Ahmed (“DashCaddy,” “we,” “us,” or “our”). By purchasing, activating, or using DashCaddy, you agree to these Terms and the <a href="/legal/privacy">Privacy Policy</a>. If acting for an organization, you represent that you can bind it.</p>
+<h2>2. License grant</h2><p>Subject to payment and these Terms, we grant a limited, revocable, non-exclusive, non-sublicensable, non-transferable license to install and use DashCaddy on <strong>one host per license</strong> for the subscription term. A license may be moved to a replacement host with approval, but not shared, resold, rented, or used concurrently on multiple hosts. DashCaddy retains all ownership and intellectual-property rights.</p><p>The license key embeds or is associated with machine metadata. A copy is stored on the licensed host in <code>data/credentials.json</code> and on our license server for validation and enforcement.</p>
+<h2>3. Acceptable use</h2><p>You must use DashCaddy lawfully and are responsible for connected systems. You must not:</p><ul><li>use proxy, DNS, credential-injection, sharing, or Tailscale features for unauthorized access, traffic interception, evasion, malware, spam, phishing, or attacks;</li><li>overload, bypass, or interfere with the Service, licensing, authentication, or security;</li><li>reverse engineer or modify DashCaddy except where law expressly permits, or remove notices;</li><li>violate privacy, intellectual-property, sanctions, export-control, or other applicable law; or</li><li>provide data or credentials you lack authority to process.</li></ul><p>We may investigate abuse and suspend access when reasonably necessary to protect users, third parties, or the Service.</p>
+<h2>4. Availability and changes</h2><p>DashCaddy v1.0 is provided on a <strong>best-effort basis with no service-level agreement (SLA)</strong>, uptime guarantee, or guaranteed response time. Maintenance, failures, third-party outages, security events, and product changes may interrupt availability. Features may change or be discontinued with reasonable notice where practical.</p>
+<h2>5. Billing, renewal, and Refund policy</h2><p>Prices, billing periods, taxes, and renewal terms appear at checkout. Stripe processes payments; card details go directly to Stripe and never touch DashCaddy servers. Unless checkout states otherwise, subscriptions renew automatically until cancelled.</p><p><strong>Refund policy:</strong> request a pro-rated refund within 14 calendar days after initial purchase. It covers the unused portion of that initial period from the request date. After 14 days, and for renewals, payments are non-refundable except where law requires. Cancellation prevents renewal but does not itself create a refund.</p>
+<h2>6. Your systems and data</h2><p>You are responsible for backups, configuration, access control, and host security. DashCaddy manages sensitive proxy, DNS, and credential-injection settings; review changes. Data handling is described in the <a href="/legal/privacy">Privacy Policy</a>.</p>
+<h2>7. Suspension and Termination</h2><p>You may stop using DashCaddy and cancel renewal anytime. We may suspend or terminate for material breach, non-payment, unlawful or abusive use, or security risk, with notice and opportunity to cure where reasonably possible. On termination the license ends. Ownership, disclaimers, liability, and governing-law provisions survive.</p>
+<h2>8. Disclaimers</h2><p>To the maximum extent permitted by law, the Service is “as is” and “as available.” We disclaim implied warranties of merchantability, fitness, non-infringement, and uninterrupted or error-free operation. DashCaddy is not represented as certified for regulated workloads and makes no SOC 2, HIPAA, or similar compliance claim. Mandatory rights remain unaffected.</p>
+<h2>9. Limitation of liability</h2><p>To the maximum extent permitted by law, DashCaddy and its operator are not liable for indirect, incidental, special, consequential, exemplary, or punitive damages, or lost profits, revenue, data, goodwill, or business interruption. Aggregate liability will not exceed amounts paid for DashCaddy in the 12 months before the claim. Limits do not apply where prohibited or to liability that cannot lawfully be limited.</p>
+<h2>10. Indemnity</h2><p>Where permitted, you will indemnify us against third-party claims from your unlawful use, connected services or data, or breach, except to the extent caused by our unlawful conduct.</p>
+<h2>11. Governing law and disputes</h2><p>These Terms are governed by laws applicable in the operator’s principal place of business, without conflict-of-law rules. Courts there have jurisdiction, except consumers retain mandatory rights and forum protections in their country. Before filing, parties will attempt resolution by email for 30 days.</p>
+<h2>12. Changes and contact</h2><p>Material changes will be posted with a new effective date and reasonable advance notice where practical. Questions, cancellation, or refunds: <a href="mailto:privacy@sami-ahmed.net">privacy@sami-ahmed.net</a>.</p><footer><a href="/legal/privacy">Privacy Policy</a><a href="mailto:privacy@sami-ahmed.net">Contact</a><a href="/">Back to DashCaddy</a></footer></main></body></html>
