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).
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).
