# Security review for 1.0.0

The 1.0.0 release follows multiple AI-assisted security scans, review of the
findings and end-to-end verification of fixes. This record describes completed
SDK and release remediation; it does not claim every repository finding is
closed or that an independent third-party audit was performed.

## Completed remediation

| Fix | Merged PR |
| --- | --- |
| Payment authorization and exact-payment retries | [#28](https://github.com/elldeeone/kaspa-x402/pull/28) |
| Atomic, bounded durable state | [#29](https://github.com/elldeeone/kaspa-x402/pull/29) |
| Bounded network I/O and transport authority | [#30](https://github.com/elldeeone/kaspa-x402/pull/30) |
| Chain evidence and grant admission | [#31](https://github.com/elldeeone/kaspa-x402/pull/31) |
| Authenticated compiler inputs and covenant reproduction | [#32](https://github.com/elldeeone/kaspa-x402/pull/32) |
| Bounded hash-chain issuer storage with recovery capacity | [#33](https://github.com/elldeeone/kaspa-x402/pull/33) |
| Release archives bound to reviewed source and compiler evidence | [#34](https://github.com/elldeeone/kaspa-x402/pull/34) |
| Explicit mainnet configuration and network binding | [#35](https://github.com/elldeeone/kaspa-x402/pull/35) |

Each linked PR records its change and verification. Original scan findings remain
historical evidence; fixes are documented through remediation records rather
than rewriting the original scans. Supporting/demo findings are not all SDK
release blockers and are not represented here as all resolved.

## Release evidence

The release source is `e5f5b0ed34657dc4e8c67c9153818e0ba07b1828`, merged in
[#37](https://github.com/elldeeone/kaspa-x402/pull/37). Its
[main CI](https://github.com/elldeeone/kaspa-x402/actions/runs/38848724921) passed
protocol/host verification, Windows checks, independent covenant reproduction
and SDK artifact preparation. The compiler is rebuilt from authenticated pinned
source; consensus validation uses pinned Rusty-Kaspa source.

The four final public SDK archives passed 55 external scenario groups and funded
Testnet-10 qualification: 18 exact/batch flows and five hash-chain stages.
The main CI archives match those qualified bytes exactly. See the
[release record](v1-release.md) and [qualification harness](../../verification/external-sdk-qualification/README.md).

The compatible demo also passed a funded payment and same-transaction retry
through the public HTTPS website and deployed Worker, Durable Object and bounded
transport relay. Its [deployment proof](https://github.com/elldeeone/kaspa-x402/blob/main/verification/release-1.0.0-hosted.json)
is separate from the earlier [local browser qualification](../../verification/demo-release-RESULTS.md).

## Limits

AI-assisted review and passing tests do not guarantee the absence of defects.
Funded evidence uses one configured Testnet authority. Stress and failure tests
use controlled acceptance facts; they do not establish live mainnet throughput,
independent-source agreement or production availability. Operators must meet the
[production operating requirements](mainnet-readiness.md) for their deployment.
