**The DeepSeek-Reasonix repository provides automated scripts and CI workflows to verify source integrity, release artifacts, and extension sidecars through cryptographic checksums and manifest comparisons.**

Verifying repository contents ensures that every source file, binary, and extension in the **DeepSeek-Reasonix** project matches the expected cryptographic fingerprints. The verification system spans three distinct levels—source integrity, release artifacts, and continuous integration guardrails—protecting against cache corruption, malicious plugins, and distribution tampering.

## Three Levels of Verification

The Reasonix verification strategy operates at distinct layers to catch discrepancies before they reach production.

### Source Integrity Verification

Individual files and the entire Git tree are validated using native Git checksums. The repository provides [`scripts/verify-release-tag.sh`](https://github.com/esengine/DeepSeek-Reasonix/blob/main/scripts/verify-release-tag.sh) to ensure that release tags point to the correct commits and optionally verify GPG signatures.

According to the source code in [`scripts/verify-release-tag.sh`](https://github.com/esengine/DeepSeek-Reasonix/blob/main/scripts/verify-release-tag.sh), the script cross-references the commit hash against [`release-notes/releases.json`](https://github.com/esengine/DeepSeek-Reasonix/blob/main/release-notes/releases.json) to confirm that tagged releases correspond to the exact intended state of the repository.

### Release Artifact Verification

Pre-built binaries, installers, and portable archives undergo rigorous validation through dedicated desktop verification scripts. The [`scripts/verify-desktop-release-directory.sh`](https://github.com/esengine/DeepSeek-Reasonix/blob/main/scripts/verify-desktop-release-directory.sh) and [`scripts/verify-desktop-release-manifest-assets.sh`](https://github.com/esengine/DeepSeek-Reasonix/blob/main/scripts/verify-desktop-release-manifest-assets.sh) utilities compare file sizes, SHA-256 hashes, and Authenticode signatures on Windows builds.

These scripts return non-zero exit codes if any mismatch is detected, preventing corrupted distributions from propagating to end users.

### CI Guardrails

The [`.github/workflows/ci.yml`](https://github.com/esengine/DeepSeek-Reasonix/blob/main/.github/workflows/ci.yml) pipeline automatically invokes verification scripts on every push and pull request. As documented in [`REASONIX.md`](https://github.com/esengine/DeepSeek-Reasonix/blob/main/REASONIX.md), developers can simulate the **pre-push CI** safety net locally using a defined checklist that includes linting, testing, and hash verification.

## Why Verification Matters for Reasonix

Verification is not merely a security formality—it is essential for the project's core architecture:

- **Cache-first prompting** – Reasonix’s system-prompt prefix is cached across turns. If source changes go undetected, the cache becomes stale and the agent may behave unpredictably.
- **Cross-platform binaries** – The project ships a single-binary Go executable for six target platforms. Any corruption breaks the "single binary" guarantee.
- **Extension sidecars** – Extension Protocol v1 sidecars and MCP servers are verified before loading via [`sdk/go/sdk.go`](https://github.com/esengine/DeepSeek-Reasonix/blob/main/sdk/go/sdk.go), preventing execution of malicious or corrupted plugins.

## Step-by-Step Verification Workflows

### Verify Release Tags Point to Correct Commits

To confirm that a Git tag resolves to the expected commit SHA and matches the recorded metadata:

```bash

# Check the commit ID associated with the tag

git rev-parse v1.2.3

# Run the repository verification script

bash scripts/verify-release-tag.sh v1.2.3

```

The script validates that the tag exists, checks for GPG signatures if enabled, and confirms the commit hash matches the entry in [`release-notes/releases.json`](https://github.com/esengine/DeepSeek-Reasonix/blob/main/release-notes/releases.json).

### Validate Desktop Binary Distributions

After downloading a release archive, verify its contents against the official manifest:

```bash

# Extract the archive

tar -xzf reasonix-1.2.3-linux-amd64.tar.gz

# Run the directory verification helper

bash scripts/verify-desktop-release-directory.sh \
    --expected-dir ./dist/linux-amd64 \
    --candidate-dir ./reasonix-1.2.3

```

This helper compares file counts, SHA-256 hashes, and on Windows platforms, validates Authenticode signatures to ensure the binaries are authentic and unmodified.

### Run Full Pre-Push CI Verification Locally

Developers can replicate the CI pipeline locally to verify repository contents before pushing changes:

```bash

# Format Go code

gofmt -w .

# Run static analysis

go vet ./...

# Execute linters (golangci-lint + repolint)

make lint

# Run unit and integration tests

go test ./...

```

If any command fails, the repository is not in a verified state and must be corrected before committing.

### Verify Extension Sidecars Before Loading

When loading extension sidecars in a Go application, the SDK automatically performs cryptographic verification:

```go
import "github.com/esengine/DeepSeek-Reasonix/sdk/go"

func loadSidecar(path string) error {
    // Automatically checks manifest SHA-256 and version
    // See docs/EXTENSION_PROTOCOL.md for the verification algorithm
    return sdk.LoadSidecar(path)
}

```

The [`sdk/go/sdk.go`](https://github.com/esengine/DeepSeek-Reasonix/blob/main/sdk/go/sdk.go) implementation hashes the entire sidecar bundle and rejects it if the hash does not match the manifest, preventing unauthorized code execution.

## Summary

- **Source integrity** is verified through [`scripts/verify-release-tag.sh`](https://github.com/esengine/DeepSeek-Reasonix/blob/main/scripts/verify-release-tag.sh), which validates Git tags against [`release-notes/releases.json`](https://github.com/esengine/DeepSeek-Reasonix/blob/main/release-notes/releases.json) using cryptographic commit hashes.
- **Release artifacts** are validated using [`scripts/verify-desktop-release-directory.sh`](https://github.com/esengine/DeepSeek-Reasonix/blob/main/scripts/verify-desktop-release-directory.sh) to ensure SHA-256 hashes and Authenticode signatures match expected values.
- **CI guardrails** in [`.github/workflows/ci.yml`](https://github.com/esengine/DeepSeek-Reasonix/blob/main/.github/workflows/ci.yml) automate verification on every pull request, while [`REASONIX.md`](https://github.com/esengine/DeepSeek-Reasonix/blob/main/REASONIX.md) documents how to run the same checks locally.
- **Extension sidecars** undergo runtime verification via [`sdk/go/sdk.go`](https://github.com/esengine/DeepSeek-Reasonix/blob/main/sdk/go/sdk.go), which implements the protocol defined in [`docs/EXTENSION_PROTOCOL.md`](https://github.com/esengine/DeepSeek-Reasonix/blob/main/docs/EXTENSION_PROTOCOL.md) to prevent loading corrupted plugins.

## Frequently Asked Questions

### How do I verify that a downloaded Reasonix binary is authentic?

Run the [`scripts/verify-desktop-release-directory.sh`](https://github.com/esengine/DeepSeek-Reasonix/blob/main/scripts/verify-desktop-release-directory.sh) script against your extracted archive. This script compares SHA-256 hashes against the official manifest and validates Authenticode signatures on Windows. Any mismatch in file size or cryptographic hash causes the script to exit with a non-zero status code, indicating the binary should not be trusted.

### What is the pre-push CI simulation mentioned in REASONIX.md?

The pre-push CI simulation is a local verification workflow documented in [`REASONIX.md`](https://github.com/esengine/DeepSeek-Reasonix/blob/main/REASONIX.md) that replicates the automated checks run by [`.github/workflows/ci.yml`](https://github.com/esengine/DeepSeek-Reasonix/blob/main/.github/workflows/ci.yml). It consists of running `gofmt`, `go vet`, `make lint`, and `go test` to ensure code quality and repository integrity before changes are pushed to the remote repository.

### Why does Reasonix verify extension sidecars at runtime?

Extension sidecars are verified at runtime via [`sdk/go/sdk.go`](https://github.com/esengine/DeepSeek-Reasonix/blob/main/sdk/go/sdk.go) to enforce the Extension Protocol v1 security requirements defined in [`docs/EXTENSION_PROTOCOL.md`](https://github.com/esengine/DeepSeek-Reasonix/blob/main/docs/EXTENSION_PROTOCOL.md). The SDK calculates SHA-256 hashes of the sidecar bundles and compares them against manifests, rejecting any plugin that fails validation to prevent the execution of corrupted or malicious code within the agent environment.

### Can I verify the repository contents without running the full test suite?

Yes. For quick verification without running `go test`, use [`scripts/verify-release-tag.sh`](https://github.com/esengine/DeepSeek-Reasonix/blob/main/scripts/verify-release-tag.sh) to check Git tag integrity or [`scripts/verify-desktop-release-directory.sh`](https://github.com/esengine/DeepSeek-Reasonix/blob/main/scripts/verify-desktop-release-directory.sh) for release artifacts. These scripts focus specifically on cryptographic hash verification rather than functional testing, providing a faster way to confirm file integrity.
