Review Closure Ledger

Status: current alpha closure notes after narrowing the shipped native surface.

This ledger records the current disposition of previously identified review themes. It intentionally tracks the package surface that remains shipped: exact and batch-settlement.

Finding themeStatusClosure evidence
Public surface must only advertise implemented native profilesFixed for current alphaSchemas, package types, examples, specs, vectors, and runtime offer selection accept only exact and batch-settlement.
Batch covenant authority must be reproducibleFixed for Alpha.10 source; mainnet audit still requiredEscrow fixture checks and transaction-v1 vectors cover singleton genesis, two partial claims against one voucher, same-ID top-up, and timeout refund. The batch interop vector preserves one stable covenant ID and reconciles A/S/T/V/R with the transaction sequence.
Transaction-v1 vectors must not be self-referentialFixed for current vectorsnpm run validate:tx-v1-consensus cross-checks the complete batch genesis, repeated-claim, top-up, and refund chain against the configured Kaspa consensus checkout.
Exact replay and batch idempotency must prevent duplicate protected executionFixed for current direct-mode testsServer and client tests cover exact replay, batch corrective state, same-id conflicts, and concurrent retries.
Exact evidence must match x402 and Kaspa-native transaction realityFixed in alpha.9 source and TN10 live proofkaspa-exact-v2 makes ordinary standard-native transfer the default and retains optional corrected additive heads. The 2026-07-19 TN10 run proved tiny and normal native payments, exact additive successor-delta economics with no second merchant output, replay/idempotency, conflict/retry, recovery, expiry rejection, and trusted external reconciliation.
Hosted exact must not advertise before Worker settlement existsFixed and paid-canary-proven for alpha.9Worker version d28e6b35-54c6-459f-b8cd-02084a769593 advertises standard-native without inventory and gates optional additive on durable head availability. The 2026-07-20 hosted canary settled 2fa08f26792721ea2b2f3e791affc6bafe7d36878d660a39dae826473cca38d7, confirmed idempotent replay, and rejected cross-resource reuse.
Live proof harness must be reproducible from committed codeProven for Alpha.10 on funded TN10The committed proof runner and reference adapter reproduced all 18 required flows in the 2026-08-10 funded TN10 run, including singleton batch genesis, stable-ID vouchers, repeated partial claims, same-ID top-up, refund, A/S/T/V/R reconciliation, and restart reload. Sanitized evidence is in docs/live-testnet-report.md; secrets and raw operational artifacts remain ignored.
HTTP and MCP transports must not release protected results before settlement succeedsFixed for current direct-mode testsServer tests cover handler failure, failed persistence, and protected-content withholding on settlement failure.
Facilitator support must not widen server capabilityFixed for current facilitator testsFacilitator tests assert supported-kind intersection and explicit claim/refund settler requirements.
Mainnet readiness must not be implied by testnet successOpen gateMainnet remains blocked by docs/mainnet-readiness.md; kaspa:mainnet is a reserved profile name only.
