// Draft of the v0.2.0 milestone version entry.
//
// NOT YET WIRED INTO `versions/index.ts` — this file sits ready to
// use when we cut v0.2.0:0 from the alpha-iteration line. To
// activate:
//   1. In `versions/index.ts`:
//        import { v0_2_0 } from './v0.2.0'
//        export const versions = VersionGraph.of({
//          current: v0_2_0,
//          other: [v0_1_0],   // ← so installs on 0.1.0:N can upgrade
//        })
//   2. Build the .s9pk (`make x86`).
//   3. Publish via `~/.keysat/publish.sh` (the version-changed gate
//      will fire because `0.2.0:0` differs from the recorded
//      `0.1.0:N`).
//
// Why this draft exists separately:
// - The cut is an irreversible release decision for already-installed
//   operators (downgrade paths exist in StartOS but they're sticky).
// - Wiring it in changes how StartOS computes the upgrade dialog
//   shown to operators on registry refresh — best to QA the
//   release-notes content in this file before flipping the switch.
// - Lets us write the v0.2.0 release notes carefully and then ship
//   them all at once, rather than amending mid-build.
//
// Version-string format reminder: ExVer is `<upstream>:<downstream>`.
// The `<upstream>` bump from 0.1.0 → 0.2.0 marks the milestone; the
// `:0` resets the downstream revision counter for the new line. The
// next routine wrapper update on the v0.2 line will be `0.2.0:1`,
// then `:2`, etc.

const RELEASE_NOTES = [
  'Keysat v0.2.0 — first non-alpha milestone. Operator-visible: web admin SPA replaces the StartOS Actions tab for day-to-day work, buyer self-service recovery, opt-in community analytics, and the wire format now agrees byte-for-byte across five language SDKs (Rust, TypeScript, Python, Go, plus the daemon itself).',
  '',
  '**The web admin SPA is the headline.** Daily operator work — creating products, configuring policies and discount codes, searching licenses, suspending/revoking, inspecting machines, registering webhook endpoints, browsing the audit log — happens in the embedded dashboard at /admin/. The StartOS Actions tab is intentionally trimmed to setup-time operations only (Connect/Disconnect BTCPay, Set operator name, Set web UI password, Activate Keysat license, Show credentials). No more "wall of buttons" for everyday tasks.',
  '',
  '**Buyer self-service recovery.** A buyer who lost their license key can re-derive it themselves from (invoice_id, buyer_email) at /recover on the daemon\'s public URL. No support ticket, no operator involvement. Per-IP rate limited (10 req/min), generic-404 on mismatch (does not leak which side of the pair was wrong), audit-logged with the email\'s SHA-256 hash so the log doesn\'t store PII.',
  '',
  '**Webhook delivery DLQ.** The outbound-webhook delivery worker has always retried failed deliveries with exponential backoff up to 10 attempts; failed deliveries past that were silent dead-letters. v0.2 surfaces them: `GET /v1/admin/webhook-deliveries?status=failed` lists them, `POST /v1/admin/webhook-deliveries/:id/retry` re-queues. Surfaced in the SPA on the Webhooks page (defaults to the "Failed" filter so the problem case is what an operator sees first).',
  '',
  '**Opt-in community analytics.** Off by default. When enabled (Overview page in the admin UI), the daemon sends a daily anonymous heartbeat: install_uuid (random, not derived from operator identity), daemon version, tier label, and counts (products / active licenses / settled invoices) floored to the nearest 5 to prevent fingerprinting an operator by their exact license count. Uptime is bucketed (<1d / 1-7d / 1-4w / >4w). Operator name, public URL, store id, API keys, buyer email are NEVER sent — and the test suite asserts none of those strings appear in the heartbeat payload.',
  '',
  '**Five-language SDK parity.** The Go SDK (github.com/keysat-xyz/keysat-client-go) lands alongside this release. Stdlib only — no third-party Go dependencies. All five implementations of the LIC1 wire format (daemon, Rust SDK, TypeScript SDK, Python SDK, Go SDK) pass the same crosscheck vectors at tests/crosscheck/vector.json byte-for-byte across v1 legacy, v2 trial-with-entitlements, and v2 perpetual-unbound fixtures.',
  '',
  '**PaymentProvider trait abstraction.** Internally, the four daemon code paths that talked to BTCPay (purchase, webhook, reconcile, tipping) all now go through the abstract PaymentProvider trait. BTCPay-specific concerns (URL rewriting, status-string normalization, metadata enrichment, payment-hash extraction) live inside the BtcpayProvider impl. This unblocks Zaprite (v0.3) — its impl drops in cleanly without touching call sites.',
  '',
  '**Test coverage.** The daemon\'s automated test count grew from ~9 in alpha-iteration :24 to 32 in :47: 9 unit + 12 API integration + 4 SQL migration regression + 4 wire-format crosscheck + 3 webhook-worker integration. Plus the four Go SDK crosscheck tests in the separate Go repo.',
  '',
  '**Upgrade from v0.1.0:N.** Straight drop-in. No new SQLite migrations on the v0.2.0:0 cut itself (those landed individually during the alpha iteration). Existing licenses, invoices, products, policies, and discount codes are untouched. Web UI password, BTCPay connection, operator name, tip-recipient configuration all carry over.',
  '',
  '**What\'s next (v0.3).** Zaprite payment provider for card payments. Recurring subscriptions. In-place tier upgrades for end customers. Multi-currency pricing (USD + sats with auto-conversion at invoice creation).',

// Routine wrapper-revision changelog. Newest first; each entry is
// what changed since the previous downstream-:N. The `:0` notes are
// in RELEASE_NOTES above (the milestone). Subsequent revisions
// append here.
const ROUTINE_NOTES = [
  '0.2.0:3 — **Durable payment-provider switching.** Fixes a gap from v0.2.0:2 where Connect Zaprite swapped the in-memory provider but BTCPay silently re-took active on the next daemon restart. Both providers\' configurations can now coexist, with a persisted preference flag determining which one is active. New "Activate BTCPay" / "Activate Zaprite" StartOS Actions let operators flip between configured providers in one click without re-running Connect. Disconnect on either provider clears the preference only if it pointed at the disconnected one — symmetric handling preserves operator intent.',
  '',
  'New endpoints: `GET /v1/admin/payment-provider/status` (both configs\' state + active preference in one call), `POST /v1/admin/payment-provider/activate` (flip active without re-authorizing). The boot-time loader now reads the persisted preference, so what an operator activates today is what loads tomorrow regardless of which config rows happen to be in the DB.',
  '',
  'Test count: 42 (added `payment_provider_preference_round_trip` covering the full lifecycle).',
  '',
  '0.2.0:2 — **Zaprite payment provider lands.** Operators can now choose between BTCPay (Bitcoin-only, you run the BTCPay Server yourself) and Zaprite (Bitcoin + fiat cards via Stripe/Square, brokered by Zaprite, settles to your connected wallets). Switching is Disconnect → Connect via new StartOS Actions ("Connect Zaprite" / "Disconnect Zaprite" / "Check Zaprite connection"). Existing BTCPay-connected operators see zero change unless they explicitly switch.',
  '',
  'How it works: paste your Zaprite API key (created at app.zaprite.com → Settings → API) into the Connect Zaprite action. Daemon validates the key, swaps the active provider atomically. Then add a webhook in your Zaprite dashboard pointing at `<your-keysat-url>/v1/zaprite/webhook`.',
  '',
  '**Webhook security.** Zaprite does NOT sign webhook deliveries (verified May 2026 against their public OpenAPI + dashboard). Keysat\'s defense is the externalUniqId round-trip: we attach our local invoice UUID at order creation, and the webhook handler trusts the body only insofar as the order id resolves to a local invoice in an expected state. An attacker spoofing a webhook would need to know a UUID we never put on the wire to reach a real local invoice.',
  '',
  '**Migration 0011 (dormant) lands the recurring-subscriptions schema** — `subscriptions` + `subscription_invoices` tables, plus `is_recurring`/`renewal_period_days`/`grace_period_days` (default 7)/`trial_days` (default 0) columns on policies. No daemon code uses these yet; phases 2-6 of `RECURRING_SUBSCRIPTIONS_DESIGN.md` ship in follow-up releases. The schema is purely additive and existing policies inherit the safe defaults.',
  '',
  '**Migration 0012** adds the `zaprite_config` table (singleton row mirroring `btcpay_config` from migration 0002).',
  '',
  '**Limitation called out cleanly:** Zaprite\'s API has no native subscription endpoints — Keysat\'s renewal worker (when it ships) drives the cycle on our side and uses Zaprite\'s `paymentProfileId` + `POST /v1/orders/charge` to charge saved cards each cycle. This is actually a cleaner model than provider-managed subscriptions because Keysat keeps the source of truth on when to bill.',
  '',
  '**Test count: 41** (was 39; +2 covering the Zaprite webhook event-parsing contract and the provider kind self-identification, +1 covering migration 0011\'s populated-data backfill contract).',
  '',
  '**Upgrade path.** v0.2.0:1 → v0.2.0:2 is a straight drop-in. Two new SQLite migrations (0011, 0012); both are additive only. No behavior change for current operators unless they explicitly run Connect Zaprite.',
  '',
  '0.2.0:1 — Buy-page discount-code box no longer shows a "FOUNDERS50" placeholder. Empty placeholder now; buyers paste their actual code without a misleading hint.',
