- .env.example: add the required at-rest identity secrets (SEED_FINGERPRINT_PEPPER,
REFRESH_TOKEN_PEPPER, IP_SALT). They were missing, so `cp .env.example .env` on a
fresh setup boot-failed closed on the first required-secret check.
- README: correct the first-admin bootstrap to `smirk-admin setup --pubkey`.
create-admin-wallet registers a pending key but does not latch, so on a fresh
instance it leaves the bootstrap uninitialized.
- docs/operations/OPERATOR_SETUP.md: full deployment guide — database, secrets,
per-chain backends, run + verify, admin bootstrap, registration policy, and
smoke-testing an instance (SMOKE_API_STYLE=namespaced).
Surfaced by a clean-room operator setup against a fresh instance.
Optional REGISTRATION_REQUIRE_PAYMENT gate: a new wallet must settle an
invoice on an external, non-custodial payment processor before it can
register. Pull model — the grant reads the processor's authenticated API as
the source of truth, so there is no inbound webhook to secure and a settled
invoice cannot be forged over HTTP. Returning wallets and self-hosting bypass
it, exactly like the invite and PoW gates.
- infra/payment: a pluggable PaymentProvider seam (neutral Invoice /
InvoiceStatus / InvoiceRequest) with a BTCPay-compatible first adapter that
also serves this project's xmrcheckout/wowcheckout apps + the BTCPay Monero
plugin, so "operator picks any coin" costs one adapter. A future ETH/native
adapter (BTCPay serves neither) implements the same trait. Only `Settled`
grants (unknown status fails safe); the API key rides in a redacting Secret
and hostile responses are size-capped.
- payment_invoices: invoice<->pubkey_hash binding + atomic single-use consume
(UPDATE ... WHERE consumed_at IS NULL AND pubkey_hash=$ RETURNING), so one
invoice grants at most one registration and never a different identity.
- POST /auth/payment-invoice mints + binds; enforce_payment (bind -> processor
`Settled` -> atomic consume) runs beside enforce_invite; payment_invoice_id
on the register request.
- Fail-closed config: https-in-prod, positive-decimal price, >= 1 confirmation
(bars a 0-conf settled-then-double-spent free registration), bounded expiry.
/capabilities advertises payment_required + price; OpenAPI + .env.example.
Tests: adapter status/speedPolicy mapping + config validation (unit), and L1
binding + atomic single-use (concurrent-consume-one-wins, mis-bind rejected).
Reviewed adversarially across payment-integrity, leak/oracle, and config/DoS
lenses; the confirmed findings (0-conf, expiry bound, Settled-means-paid-in-full
adapter contract, rotation-branch bypass guard) are addressed here.
Default restore policy is now create-only — which betrays no self-sovereignty,
since that lives at the ECOSYSTEM level (run your own backend). On top of the
create-only|bounded|unlimited depth gate, restore depth can be PRICED in hashcash
PoW so an importer pays compute proportional to the chain-scan cost they impose
on the operator (deeper restore => more work).
- core::restore_pow: a self-contained hashcash bound to (asset, address,
start_height) — a solved nonce is valid only for that exact restore, so no
challenge state, no replay, no depth-downgrade. Difficulty = leading zero bits.
- RestoreConfig: pow_free_days / pow_days_per_bit (0 = off) / pow_max_bits curve;
required_restore_pow_bits + enforce_restore_pow (literal errors, no oracle).
- Enforced at xmr/wow register + grin scan via a new restore_pow_nonce; the curve
is advertised via /capabilities so the wallet computes + solves it.
- Default WALLET_RESTORE_POLICY flipped bounded -> create-only.
- Unit tests (curve scaling/cap, off-when-zero, valid/invalid nonce, hashcash
roundtrip + param-binding); .env.example; OpenAPI drift clean.
First of the operator-configurable registration gates (PoW-priced restore and
pay-to-register follow). A NEW wallet must present a valid invite code when
REGISTRATION_REQUIRE_INVITE is on; returning wallets and self-hosting bypass it,
and the active gates are advertised via /capabilities so the wallet shapes
onboarding.
- migration + db: invite_codes table storing only sha256(code) (128-bit codes,
no pepper needed). Redemption is an atomic single-statement claim
(UPDATE ... WHERE used_at IS NULL RETURNING) — single-use even under concurrent
submission (L1 test fires 8 concurrent claims; exactly one wins).
- core::invite: generate (base58, 128-bit) + sha256 hash.
- enforce_invite in extension_register, mirroring enforce_pow (returning bypass;
ONE literal error for not-found/used/expired — never an oracle).
- RegistrationConfig.require_invite + RegistrationCapability in /capabilities.
- smirk-admin mint-invite --count/--label (prints raw codes once; stores hashes).
- L1 tests (single-use + concurrency race), .env.example, OpenAPI (drift clean).
How far back a wallet may ask THIS instance to scan on import is an operator
decision — the backfill cost lands on its LWS/node. Add WALLET_RESTORE_POLICY
(create-only | bounded | unlimited, default bounded) + WALLET_MAX_RESTORE_DEPTH_DAYS,
advertise it via /capabilities so the wallet adapts its import UX, and enforce
it at the scan path (xmr/wow register, grin scan): a too-deep start_height is a
ValidationError naming the bound, never the caller's value. Create needs no
check (no tip lookup). Self-sovereignty stays intact at the ecosystem level —
a deeper restore means self-hosting or a looser operator. Fail-closed config
validation; a unit test per policy; OpenAPI drift clean.
