Replay Command Generator Service

Module

Cli

Status

IMPLEMENTED

Description

Backend service that generates copy-ready replay commands for deterministic verdict reproduction. Builds command strings with all necessary hashes (artifact, manifest, feeds, policy) and provides downloadable evidence bundles as ZIP for one-click replay from the UI.

Implementation Details

  • Replay Infrastructure: src/Cli/StellaOps.Cli/Replay/ -- replay command generation
  • Determinism Harness: src/Cli/StellaOps.Cli/Services/DeterminismHarness.cs -- determinism enforcement
  • Commands:
    • stella replay generate <digest> -- generate replay command with all input hashes
    • stella replay bundle <digest> --output <path> -- download evidence bundle as ZIP
  • Output: Copy-ready command string with all hashes pinned for deterministic reproduction

E2E Test Plan

  • Run stella replay generate sha256:abc123 and verify command string output
  • Verify generated command includes artifact hash, manifest hash, feeds hash, policy hash
  • Run the generated command and verify deterministic reproduction
  • Run stella replay bundle sha256:abc123 --output ./replay.zip and verify ZIP created
  • Verify ZIP bundle enables offline replay
