Grant 9eba309a8f v0.2.0:2 — Zaprite payment provider + recurring subscriptions schema foundation
This release adds Zaprite as an alternative to BTCPay. Operators
can now choose between two payment rails:
- BTCPay: Bitcoin-only, you run the BTCPay Server yourself
- Zaprite: Bitcoin + fiat cards (USD/EUR via Stripe/Square), brokered
  by Zaprite, settles to your connected wallets

Only one is active at a time per Keysat instance. Switching requires
Disconnect → Connect; existing license keys are unaffected. Future
v0.3 work routes per-policy choice (e.g., "free tier via Zaprite,
paid tier via BTCPay") if operators want both, but for v0.2.0:2 it's
either-or.

What's in this release:

**Migration 0011 — recurring subscriptions schema (dormant).**
Adds `subscriptions` and `subscription_invoices` tables, plus
`is_recurring`/`renewal_period_days`/`grace_period_days` (default 7)/
`trial_days` (default 0) on policies. No daemon code uses these
yet — phases 2-6 of RECURRING_SUBSCRIPTIONS_DESIGN.md land in
follow-up commits. Migration regression test covers the additive
contract against populated data.

**Migration 0012 — zaprite_config.** Singleton-row table for the
operator's Zaprite API key + base URL + recorded webhook id.
Mirrors btcpay_config from migration 0002.

**ZapriteProvider implementation.** New module at
src/payment/zaprite/ with client.rs (HTTP, Bearer auth), config.rs
(DB persistence), provider.rs (PaymentProvider trait impl). Maps
Zaprite's currency enum (BTC/USD/EUR) to/from the Money type;
maps Zaprite's order status enum (PENDING/PROCESSING/PAID/COMPLETE/
OVERPAID/UNDERPAID) to ProviderInvoiceStatus.

**Webhook security via externalUniqId round-trip.** Zaprite does
NOT publish a webhook signature scheme (verified May 2026 against
public OpenAPI + dashboard). Their docs explicitly designate
receiver-side idempotency as the security model. Keysat's defense:
attach our local invoice UUID as externalUniqId at order creation,
then trust the webhook only insofar as the order id resolves to
a local invoice in an expected state. Documented in detail in the
payment::zaprite module-level comment + the validate_webhook
docstring.

**Admin endpoints.**
- POST /v1/admin/zaprite/connect: validates the API key by pinging
  GET /v1/orders before persisting; swaps active provider atomically
- POST /v1/admin/zaprite/disconnect: clears stored creds + provider
- GET  /v1/admin/zaprite/status: read-only connection snapshot
- POST /v1/zaprite/webhook: webhook landing route (alias of the
  existing /v1/btcpay/webhook handler since validate_webhook is
  trait-level)

**StartOS Actions** under a new "Zaprite" group: Connect Zaprite,
Check Zaprite connection, Disconnect Zaprite. Operator pastes the
API key into a masked input; daemon validates + saves.

**Tests.** Two new in tests/api.rs (zaprite_webhook_event_parsing
covers the full event-type mapping + missing-id rejection +
malformed-JSON rejection; zaprite_provider_kind pins the
identification). Migration regression test for 0011. Test count
grows 39 → 41.

Operators on BTCPay see no change. Operators wanting Zaprite go
through the StartOS Actions tab → Connect Zaprite, paste their
API key, register a webhook in Zaprite's dashboard pointing at
their public Keysat URL + /v1/zaprite/webhook.

Recurring subscriptions are NOT yet operator-visible — schema only
in this release. Daemon-code that uses the subscriptions tables
(renewal worker, validate-hot-path subscription branch, admin UI)
lands in subsequent commits per the design doc's phased plan.

Grant 4251e96082 Migration 0011 — recurring subscriptions schema (committed, not published)
Foundation-only commit. Adds the storage shape for recurring-billing
licenses; daemon code that uses these tables (renewal worker,
validate-hot-path subscription branch, admin endpoints, buy-page
recurring rendering) lands in subsequent commits.

Schema changes (all additive):
- policies gains: is_recurring, renewal_period_days,
  grace_period_days (default 7), trial_days (default 0).
- New table `subscriptions` — one row per subscription-backed
  license (1:1 via license_id UNIQUE). Tracks the cycle state
  machine: active / past_due / cancelled / lapsed.
- New table `subscription_invoices` — one row per renewal-cycle
  invoice. Joins subscriptions to the existing invoices table.
  UNIQUE(subscription_id, cycle_number) prevents double-billing
  the same cycle.

Pricing snapshot (listed_currency / listed_value / period_days)
is FROZEN at subscription creation. Operator changing the
underlying policy's price doesn't affect existing subs; the next
renewal still bills the snapshotted amount. Per
RECURRING_SUBSCRIPTIONS_DESIGN.md.

Migration regression test (migration_0011_adds_subscriptions_without
_breaking_existing_data) seeds realistic fixtures pre-0011, applies
0011, asserts:
  - existing policies default to non-recurring with grace=7,
    trial=0
  - new tables accept rows via FKs into pre-0011 license/policy/
    invoice rows
  - status CHECK rejects garbage values
  - subscription_invoices UNIQUE(sub_id, cycle_number) prevents
    duplicate cycle inserts
  - foreign_key_check + integrity_check both clean post-migration

Test count: 39 (was 38). Tests all pass:
  9 unit + 16 API + 4 crosscheck + 7 migration + 3 worker.

Defaults encoded:
  - grace_period_days = 7  (per RECURRING_SUBSCRIPTIONS_DESIGN
    open question 1; my recommended default)
  - trial_days included as a column from day 1 (per open question
    3; cheaper to ship now than migrate later)
  - cancellation refund: not a schema concern — just stops next
    charge, license stays valid through current cycle (per
    open question 2; my recommended default)

If Grant comes back with different answers, the defaults can be
tuned via ALTER COLUMN DEFAULT in a follow-up migration. Existing
subscriptions wouldn't be affected (they snapshot grace_period_days
at creation in their policy_id reference, not directly in the
subscription row — this might need rethinking once the renewal
worker lands; flagged for the next pass).

Not bumped / published — operator-visible only once the daemon
code that uses these tables ships. Ready to publish whenever
Grant approves the open-question defaults.

Grant 9919fbf8f8 v0.1.0:50 — auto-recover from sqlx checksum drift on idempotent migrations
Two operators in a row hit the same crash-loop on upgrade:

  Error: running migrations
  Caused by:
      migration 9 was previously applied but has been modified

sqlx records a SHA-384 of each migration's bytes when first applied,
then verifies the on-disk bytes still match on every subsequent boot.
Cross-build drift (trailing newlines, line-ending normalization, etc.)
produces different bytes for semantically-identical SQL — and sqlx
refuses to start. Recovery required SSHing in and running:

  sqlite3 /data/keysat.db "DELETE FROM _sqlx_migrations WHERE version = 9;"

That's bad UX. Worse, every operator going through this version
range hits it once.

Self-heal: db::init now wraps sqlx::migrate!().run() with detection
for MigrateError::VersionMismatch(N) on a constant allowlist of
migrations certified safe to re-run (IDEMPOTENT_MIGRATIONS, just [9]
for now). When triggered, the daemon clears the stale row, retries,
logs a WARN explaining what happened, and continues. No SSH dance.

Allowlist gate is critical — auto-clearing checksums on additive
ALTER TABLE migrations like 0010 would error on retry (SQLite has
no ADD COLUMN IF NOT EXISTS). Only migrations explicitly designed
as drop-and-rebuild (like 0009) and tested via the
`migration_NNNN_is_idempotent` pattern in tests/migrations.rs
qualify.

Regression test in tests/migrations.rs exactly simulates the
production incident:
  1. apply all migrations cleanly
  2. poison v9's recorded checksum with bogus bytes
  3. confirm raw sqlx::migrate! bails (proves the poisoning works)
  4. call db::init — must succeed by clearing + re-applying v9
  5. confirm v9 + v10 are both recorded with non-poisoned checksums

Test count: 38 (was 37; +1 db_init_self_heals test).

For operators currently stuck on the :49 crash-loop: just upgrade
to :50 from the StartOS marketplace. The :50 daemon will see the
mismatch on first boot, auto-clear v9's row, re-apply (0009 is
idempotent by design), and continue to 0010. No manual sqlite3 needed.

Grant d8aa9c22b9 Multi-currency Phases 3, 5, 6 — buy page, invoice rate recording, discount currency
Phase 5 (invoice records the rate):
- repo::create_invoice_with_currency takes the listed currency,
  listed value, exchange_rate_centibps, and exchange_rate_source as
  optional params; create_invoice (the legacy form) becomes a thin
  wrapper that passes None for all four. SAT-priced flows are
  unchanged.
- purchase::start now branches on product.price_currency: SAT keeps
  the existing path; USD/EUR calls rates::convert_to_sats and pins
  the listed price + rate to the local invoice row for audit. The
  buyer is still billed in BTC (BTCPay invoice is sat-denominated)
  but the audit trail records what they SAW vs what they were
  charged.
- Test paid_purchase_in_usd_records_listed_currency_and_rate seeds
  a manual rate pin ($50k/BTC), creates a USD-priced product
  ($49.00), runs through purchase, asserts the invoice row carries
  listed_currency='USD', listed_value=4900, rate_centibps=
  500_000_000, source='manual_pin', amount_sats=98_000.

Phase 3 (buy page renders fiat):
- Server-rendered initial price respects product.price_currency:
  USD products show "49.00 USD" (cents converted to display dollars)
  instead of sats. Tier-picker JS still formats per-tier prices in
  sats — that's a v0.3 polish when we plumb the rate into the JS
  render path. Most operators ship single-policy products at first,
  so the static initial render is the high-leverage piece.

Phase 6 (currency-aware discount codes):
- POST /v1/admin/discount-codes accepts optional `discount_currency`
  field ('SAT' default, 'USD', 'EUR'). Whitelisted in the handler.
- repo::create_discount_code is now a thin wrapper around
  create_discount_code_with_currency; the new helper persists
  discount_currency to the column added in 0010. Existing SAT-only
  codes keep working unchanged.

Test count: 37 (was 36; +1 paid_purchase_in_usd test).

Multi-currency design phases 1-6 all shipped (1: schema in :48; 2:
admin UI write in :48-:49; 3: buy page; 4: rate fetcher; 5: invoice
audit; 6: discount currency). Phase 7 (recurring subscriptions
re-quote) is v0.3 territory — needs the recurring-billing scaffolding
from Zaprite first.
2026-05-08 12:21:26 -05:00
Grant eb885502ba Multi-currency Phase 4 — rate fetcher with Kraken/Coinbase/CoinGecko fallback
src/rates.rs adds an in-memory rate cache (60s TTL) with a 3-source
fallback chain. AppState gains `rates: Arc<RateCache>`. Manual pins
via the settings table override the chain — used by tests for
deterministic conversions and by operators during maintenance
windows.

Admin endpoints:
- GET /v1/admin/rates: cache snapshot
- POST /v1/admin/rates/refresh: force re-fetch (audit-logged)

Two new tests (network-free, manual-pin path):
- rate_cache_honors_manual_pin_from_settings
- admin_rates_endpoint_reflects_manual_pin

Test count: 36 (was 34).
2026-05-08 12:16:22 -05:00
Grant 356d17fdde Multi-currency Phase 2 — admin write path (currency picker)
Backend:
- POST /v1/admin/products accepts both forms:
  - legacy: { price_sats: 50000 }
  - typed:  { price_currency: 'USD', price_value: 4900 }
  Whitelist enforced (SAT|USD|EUR). Mismatched legacy + typed → 400
  to catch half-migrated clients sending stale price_sats alongside
  fresh price_value.
- repo::create_product_with_currency: SAT → dual-write price_sats =
  price_value; USD/EUR → price_sats = 0 until first invoice creation
  triggers a rate lookup (Phase 4 + 5).
- Test admin_create_product_accepts_legacy_and_typed_currency_forms
  pins 6 happy/sad paths.

Frontend (Products page):
- Create-product form has a currency picker (sats / USD / EUR).
  Picker swaps the unit hint + step in place.
- Decimal entry on USD/EUR is converted to cents on the way out.
- Products table renders prices via formatProductPrice(): USD
  products show "$49.00" with optional "≈ 75k sats" hint.

Test count: 34 (was 33).
2026-05-08 12:11:36 -05:00
Grant d8fcb51d1c Multi-currency schema foundation (Phase 1 of MULTI_CURRENCY_DESIGN)
Migration 0010 adds the columns needed to price products + policies
in something other than satoshis (USD, EUR, BTC at higher denoms)
while keeping every existing operator's data behaviorally identical.
This is the foundation work; admin UI write path, buy page
rendering, and rate fetcher land in subsequent phases. See
MULTI_CURRENCY_DESIGN.md at the parent licensing/ folder for the
full design.

Schema changes (all additive):
- products gain price_currency (TEXT NOT NULL DEFAULT 'SAT') and
  price_value (INTEGER NOT NULL DEFAULT 0). Backfill copies
  price_sats → price_value on every existing row, so SAT-priced
  products carry their information identically through the
  migration.
- policies gain price_currency_override (nullable, NULL = inherit
  from product) and price_value_override (nullable, mirrors the
  existing price_sats_override).
- invoices gain four nullable columns: listed_currency, listed_value,
  exchange_rate_centibps, exchange_rate_source. NULL on every
  current row; populated by the daemon when an invoice is created
  against a fiat-priced product.
- discount_codes gains discount_currency (DEFAULT 'SAT'). 'percent'
  codes are currency-agnostic; 'fixed_sats' and 'set_price' codes
  use this column to express "$10 off" or "set price to $25"
  against fiat-priced products.
- New index idx_products_currency for future "list products by
  currency" admin views.

Read path:
- Product struct gains price_currency + price_value fields
  (#[serde(default)] for back-compat with any cached/persisted
  shapes that predate them).
- row_to_product extracts the new columns; falls back to SAT/
  price_sats if a row predates 0010 (defensive — migration always
  runs at boot, but no reason to crash if it didn't).
- All four product SELECTs add the new columns.

Write path (legacy SAT-only callers):
- create_product dual-writes price_sats AND price_value to the
  same value, with price_currency = 'SAT'.
- update_product dual-writes price_sats and price_value when the
  caller passes a new sat price.

Migration regression test:
- migration_0010_backfills_existing_products_to_sat seeds three
  products (free, $100, $2500-equivalent) and a policy with a
  sat override BEFORE 0010 runs, applies 0010, asserts every row
  ends up with price_currency = 'SAT' and price_value =
  price_sats. Catches any future change that breaks the
  backfill contract.
- migration_0009_is_idempotent now pinned to 0009 by filename
  (was: "the last migration"). 0010+ are not idempotent (ALTER
  TABLE ADD COLUMN can't be retried in SQLite); the
  idempotency test is specifically for 0009 because that
  migration's whole point was being safely re-runnable.

Test count: 33 (was 32; +1 migration_0010_backfills test).

Decisions locked in (per MULTI_CURRENCY_DESIGN open questions):
- Default currency on new products: SAT. Operators explicitly
  pick USD for fiat-priced products.
- Multi-currency available to all tiers (NOT gated behind Pro/
  Patron) — the right product call.
- Rate source priority: Kraken → Coinbase → CoinGecko (lands
  in Phase 4 of the design).
- Recurring subscriptions: SAT-priced subs charge the same sat
  amount each cycle (no rate adjustment needed); USD-priced subs
  re-quote each cycle so the dollar amount is stable.

Grant d827b1aaab Opt-in community analytics + admin UI surface
Closes the last T2 plan item. Off by default; toggling on requires
the operator to confirm a collector URL (an empty URL is "armed but
silent"). The toggle lives on the admin Overview page next to the
public-key card — the right place for a privacy-affecting choice
since it's where operators actually live.

What's sent (per the in-card "Show me exactly what gets sent"
disclosure, and pinned by the test):
- install_uuid: random UUIDv4 generated on first opt-in. NOT
  derived from operator_name, store id, public URL, or any
  other identifier. Wipeable via the Reset button.
- daemon_version (CARGO_PKG_VERSION).
- tier (creator/pro/patron/unlicensed) — the same string the
  admin tier endpoint already exposes.
- counts: products, active_licenses, settled_invoices — each
  floored to the nearest 5 (anti-fingerprinting; an exact license
  count uniquely identifies an operator over time).
- uptime_bucket: <1d / 1-7d / 1-4w / >4w (bucketed, not exact).

What's NOT sent (test asserts none of these strings appear in the
preview heartbeat): operator_name, public_url, store_id, api_key,
buyer_email, btcpay_url. Also no product/policy slugs or names, no
license/invoice ids, no fingerprints, no webhook secrets.

Backend:
- src/analytics.rs — heartbeat builder, opt-in check, daily
  background tick (5min initial grace period after boot).
- src/api/community.rs — GET / POST / reset admin endpoints.
- main.rs spawns the background tick unconditionally; the tick
  is a no-op if disabled OR no collector URL configured.

Frontend (web/index.html, Overview page):
- Toggle + collector URL input + privacy disclosure showing the
  EXACT JSON shape that would be sent (renders the live preview
  heartbeat from /v1/admin/community-analytics).
- "Reset install_uuid" button so an operator who's been beaconing
  under one identifier can start fresh.

Also includes the configureBtcpay.ts idempotency change from
v0.1.0:46 (already committed; touched again here only because the
diff includes the .ts file in the same dirty-tree push).

Test count: 32 (was 31; +1 community_analytics_opt_in_and_privacy_contract
which seeds 23 licenses and verifies the heartbeat reports 20 —
proves the floor-to-5 anti-fingerprinting is in effect).
2026-05-08 11:35:50 -05:00
Grant f6ba1c160e Buyer self-service recovery + db-info admin endpoint
Two operator-facing additions, both addressing risks we'd flagged
earlier in the v0.2 plan but hadn't shipped.

**POST /v1/recover (+ GET /recover HTML form).** Lets a buyer who
lost their license key re-derive it themselves by presenting their
invoice id + the email they paid with. Until now, the recovery
flow was "DM the operator with your invoice id and they re-send" —
operator-time scaling badly. With this, the buyer self-serves and
the operator never has to know.

The endpoint takes (invoice_id, email), case-insensitive on email.
Returns a generic 404 on any mismatch — does NOT distinguish
"invoice not found" from "wrong email" so an attacker can't
brute-force email addresses against a known invoice id. Per-IP
rate limited at 10 requests / minute. Audit-logged as
license.recovered with the email's SHA-256 hash so PII isn't
written to the log.

The HTML form at GET /recover is server-rendered, no JS framework,
no cookies — designed for a customer who's just had a catastrophic
failure of their primary computer and reached us from whatever
device they could find.

Test in tests/api.rs:recover_returns_license_key_for_matching_pair
exercises the happy path (case-insensitive email match), the
generic-404 paths (wrong email, missing invoice), the round-trip
(recovered key validates via /v1/validate), and the audit-log
write.

**GET /v1/admin/db-info.** Cheap insurance against the
catastrophic-loss risk: /data/keysat.db is a single SQLite file,
losing it invalidates every license ever issued. StartOS's backup
machinery handles snapshotting; this endpoint gives operators a
sanity-check surface they didn't have before:
  - DB file path + on-disk size
  - last-write timestamp (max across audit_log, invoices, licenses)
  - row counts for products, policies, licenses (total + active),
    invoices (total + settled), machines (active), discount codes,
    audit log entries

Doesn't report when StartOS last backed it up — the daemon has no
visibility into the host's snapshot subsystem. What it gives the
operator is a "I expected ~50 licenses and I see ~50 licenses; the
file is N MB; the last write was 6 hours ago" check.

Test count: 31 (was 30; +1 for the recover test).
2026-05-08 11:05:10 -05:00
Grant 655e0d51f8 Daemon-side wire-format crosscheck
Loads tests/crosscheck/vector.json (the same file the TS, Python, and
Rust SDKs each test against independently) and verifies the daemon's
crypto::parse_key produces field-by-field identical values.

What was missing: the SDKs each ran their crosscheck against the
shared vectors, but the **daemon itself** never did. The daemon
shares no parser code with the SDKs (separate trees, separate
implementations of the same byte layout), so drift in the daemon's
parser could ship undetected until an SDK on the wire couldn't
validate a daemon-issued key.

Four tests, one per fixture in vector.json (v1 legacy fingerprint-
bound, v2 trial with entitlements, v2 perpetual unbound), plus a
sanity check that publicKeyPem is present.

Each fixture asserts: version, product_id UUID, license_id UUID,
issued_at, expires_at, flags + derived `is_fingerprint_bound`/
`is_trial` getters, entitlements (order-sensitive), and the 32-byte
fingerprint_hash bytes hex-encoded. When `fingerprintRaw` is
provided and binding is active, hashes the raw fingerprint with
crypto::hash_fingerprint and asserts the result matches the wire
bytes — pinning the SHA-256 contract the SDKs depend on.

Signature verification is intentionally out of scope: the unit
tests in src/crypto/mod.rs already prove daemon's sign/verify
roundtrip works, and the SDKs prove the same key verifies in three
independent crypto implementations. The parser-to-fields contract
is what hadn't been pinned from the daemon's side, and what this
file enforces.

Test count: 30 (9 unit + 4 migration + 10 API + 3 worker + 4
crosscheck), up from 26.
2026-05-08 10:43:36 -05:00
Grant 5ec9a6e8c0 Migrate reconcile + tipping onto PaymentProvider trait; add worker tests
Two compat-path holdovers migrated:

- src/reconcile.rs: was state.btcpay_client().get_invoice() with
  manual JSON parsing of BTCPay-specific status strings ("Settled",
  "Complete", "Expired", "Invalid"). Now state.payment_provider()
  .get_invoice_status() returning the typed ProviderInvoiceStatus
  enum. The string normalization moves into BtcpayProvider's impl
  where it belongs.

- src/tipping.rs: was state.btcpay_client().pay_lightning_invoice()
  returning raw JSON, then manual paymentHash extraction. Now
  provider.pay_lightning_invoice() returning a typed PaymentReceipt
  { payment_hash, raw }. The audit message now records the active
  provider's kind() rather than hardcoding "BTCPay LN node".

Combined with v0.1.0:43's purchase migration, the daemon's
non-test code now contains zero calls to state.btcpay_client() or
.btcpay_webhook_secret(). Those compat accessors stay on AppState
for v0.2 (no need to break things gratuitously) but they're dead
code in the production path. Zaprite's drop-in only needs to
implement the trait.

Worker integration tests (tests/worker.rs):

- worker_marks_failure_and_schedules_retry_on_500: spins up a tiny
  axum receiver that 500s, calls webhooks::tick(), verifies attempt
  count and next-attempt scheduling.
- worker_dead_letters_after_max_attempts: seeds a row at attempt
  count 9, ticks once, verifies attempt_count → 10 and
  next_attempt_at → NULL. Confirms the row also satisfies the admin
  DLQ predicate (the contract :43's webhook_deliveries.rs depends
  on).
- worker_marks_success_on_2xx: pins the happy path.

webhooks::tick is now `pub` so integration tests can drive it
synchronously.

Test count: 26 (9 unit + 4 migration + 10 API + 3 worker).
2026-05-08 10:40:11 -05:00
Grant f9ef1a854c Webhook DLQ — list failed deliveries and manually retry
Closes the silent-loss hole in outbound webhook delivery. The worker
in src/webhooks.rs retries failed deliveries with exponential backoff
up to 10 attempts, then sets next_attempt_at = NULL and walks away.
Pre-this-commit, those "dead-lettered" rows sat in webhook_deliveries
forever with no surface for the operator to discover, inspect, or
recover from them — a subscriber that was down for >6h during a
license-issuance burst would silently lose those events forever.

What's new:

- repo::DeliveryStatusFilter — enum with parse() so query strings
  map cleanly to SQL predicates.
- repo::list_deliveries — endpoint_id + status + limit, newest first.
- repo::requeue_delivery — resets attempt_count=0, clears delivered_at
  and last_error, sets next_attempt_at=now. The worker picks it up on
  the next 5s tick.

- src/api/webhook_deliveries.rs — admin module with two handlers:
  - GET /v1/admin/webhook-deliveries?endpoint_id=…&status=…&limit=…
  - POST /v1/admin/webhook-deliveries/:id/retry  (audit-logged as
    webhook_delivery.retry; 404 on missing id)
- Routes registered in src/api/mod.rs alongside the existing
  webhook_endpoints CRUD.

- tests/api.rs gains webhook_dlq_lists_failed_and_retry_requeues:
  seeds three deliveries directly via SQL (one each: delivered,
  pending, dead-lettered), exercises the list filter, runs the retry,
  asserts the row migrates from failed→pending, audit row is written,
  404 on bad id, 400 on bad status filter.

Worker code is unchanged. The DLQ is operator-actionable infrastructure
on top of the existing retry semantics.

Test count: 23 (9 unit + 4 migration + 10 API), up from 22.
2026-05-08 09:38:58 -05:00
Grant e2b296ce29 Migrate purchase::start onto PaymentProvider trait + paid-purchase test
Drops the legacy compat path. `purchase::start` now calls
`state.payment_provider().await?.create_invoice(CreateInvoiceParams {
...})` instead of `state.btcpay_client().await?.create_invoice(...)`.
Provider-specific concerns (BTCPay's checkout-URL rewriting from the
internal Docker hostname to the public domain, metadata enrichment
with `orderId` / `source`) move inside the BtcpayProvider impl where
they belong; the same code path now serves any future provider
(Zaprite, etc.) without fork/copy.

URL rewriting is removed from the caller (no longer needs to know
which provider's URLs to rewrite or how). The
`crate::payment::btcpay::rewrite_to_public` function stays on the
provider impl; pubpath unchanged.

Adds `paid_purchase_creates_invoice_via_provider` integration test —
previously deferred per :42's release notes because the compat path
prevented MockPaymentProvider from substituting. Now the mock works
through the same call site as production. Verifies:
  - daemon delegates invoice creation to the provider
  - returned provider_invoice_id is stamped on the local invoice row
  - checkout_url is what the provider returned
  - no license issued at this stage (that's the webhook's job)

Test count: 22 (9 unit + 4 migration + 9 API).
2026-05-08 09:35:41 -05:00
Grant 34704bfa03 Add tier-cap enforcement test
Verifies the 402 PAYMENT_REQUIRED gate on /v1/admin/products fires at
the Creator-tier product cap (5), and that swapping `self_tier` to a
Licensed tier with `unlimited_products` lifts the cap without a
daemon restart. Mirrors what the admin UI's "Activate Keysat license"
flow does at runtime.

Validates two production-correctness invariants:
  - the 402 carries an `upgrade_url` so the SPA can render the
    upgrade CTA inline (rather than a generic error)
  - the failed attempt does NOT leak a row into the products table —
    the cap fires BEFORE the insert

Grant c11764898b v0.1.0:42 — webhook idempotency test + free-purchase test
Two new API integration tests, both targeting production-correctness
invariants worth locking down:

- free_purchase_issues_license_inline: exercises the price=0 shortcut
  (price_sats_override=0 on a "free" tier policy). Verifies the daemon
  synthesizes a settled invoice locally, issues a license inline, and
  the inlined license_key validates round-trip via /v1/validate.

- webhook_settles_invoice_and_issues_license_idempotently: the most
  important new test in this set. A pending invoice + an InvoiceSettled
  webhook → license issued, status flipped. Re-delivering the SAME
  webhook (which providers DO retry, sometimes aggressively) must NOT
  duplicate the license. A duplicated license here means duplicated
  revenue and duplicated revocation surface area — both bad. This test
  pins the invariant.

MockPaymentProvider added to tests/api.rs: a test-only PaymentProvider
impl that bypasses HMAC verification and parses test-supplied JSON
bodies into ProviderWebhookEvent variants. Lets us drive deterministic
settle/expire/invalid events without a real BTCPay roundtrip. Never
compiled into the production binary.

Paid-purchase test deferred: purchase::start still uses the legacy
state.btcpay_client() compat accessor that downcasts to the concrete
BtcpayProvider, which the mock can't satisfy. Documented inline. Slots
in trivially after the trait migration on the v0.3 backlog.

Version bump to v0.1.0:42 with release notes covering everything since
:41 was published: lib.rs library refactor, the original 5 API tests
from 81066df, the 2 new ones above, KEYSAT_INTEGRATION.md restoration.
No daemon-behaviour changes for operators; straight drop-in upgrade
from :41.

Test count: 20 (9 unit + 4 migration + 7 API), up from 13 in :41.

Grant 81066dfe62 Add API endpoint integration tests + library scaffolding
Closes the next-biggest test gap after migration tests. The daemon has
54+ HTTP endpoints, all previously untested at the request/response
level — same shape of blind spot that allowed the v0.1.0:39 migration
bug to ship.

What's new:

- src/lib.rs — exposes the daemon's modules as a library so integration
  tests can import them (`pub mod api;`, etc.). Module source files are
  unchanged; main.rs now imports via `use keysat::...` instead of
  declaring `mod api;` directly. No runtime behaviour change in the
  binary.

- tests/api.rs — 5 integration tests that drive real HTTP requests
  through axum::Router::oneshot against a real SQLite tempfile pool
  (same options as src/db/mod.rs::init):
    1. health_endpoint_returns_200 — framework smoke test
    2. admin_endpoint_rejects_missing_or_wrong_auth — 401 vs 403 paths
    3. admin_creates_product_with_correct_token — full happy path
       (auth → handler → DB insert → audit log → response)
    4. validate_rejects_unsigned_garbage — early parse-fail surfaces
       as `ok: false, reason: "bad_format"` (HTTP still 200)
    5. validate_accepts_well_formed_license — issues a license via
       repo, signs a matching LicensePayload with the daemon's
       actual key, encodes to wire format, validates via the
       endpoint, asserts ok=true plus populated metadata fields

Test count: 9 unit + 4 migrations + 5 API = 18 (was 13).

Cargo.toml dev-deps gain `tower = { version = "0.4", features = ["util"] }`
for ServiceExt::oneshot. The main `tower` dep is feature-minimal because
axum only needs a subset.

Out of scope (explicit follow-ups):

- Purchase happy path (needs a MockPaymentProvider implementing the
  trait; ~250 LOC of mock + ~200 LOC of test).
- Webhook handler with idempotency assertions (same MockPaymentProvider
  dependency).
- Tier-cap enforcement (mechanically simple; small follow-up PR).
- Discount-code atomic reserve race (better as a SQL-layer unit test
  than an HTTP integration test).
- Rate-limiting (interacts with shared state; needs careful isolation).
- Cookie/session auth (already covered in session_layer.rs).

Grant 116ed0d1f8 v0.1.0:41 — second hotfix to migration 0009; migration regression tests
The v0.1.0:40 migration was correct on clean installs but crashed at
COMMIT on any database with rows in discount_redemptions: SQLite's
deferred FK check saw the dropped parent's bookkeeping as unsatisfied
even after the rename. Fix is to rebuild discount_redemptions in the
same transaction (stash → drop → rebuild → restore) plus orphan
cleanup. Migration is idempotent; operators on :40 with a checksum
mismatch recover by deleting the version=9 row from _sqlx_migrations
and restarting.

Lands the missing migration test scaffolding too. The four tests in
licensing-service/tests/migrations.rs apply migrations against a
realistic populated database (products, policies, invoices, licenses,
machines, discount codes, redemptions, webhooks, tip attempts). The
regression test fails with the exact 787 error against the v40
migration — would have caught the bug pre-release.

KEYSAT_INTEGRATION.md is removed from this repo; it now lives in the
parent licensing/ folder.
