10f1994fe1 feat(environment): serve an environment manifest as a replay environment (#4975)
Serve retained capture Evidence as a bounded MCP replay environment with discovery.
Preserve default stdio, caller-selected facts and complete source Evidence.

Fix numeric fidelity, argument identity, startup cancellation and bounded discovery,
query/path matching and output metadata. Verify real recorded API data and public
CLI/MCP workflows; preserve explicit gaps for Windows and third-party hosts.

Keep the evidence Analysis runs locally and returns observations, limitations, and unknowns through the CLI and MCP. /mcp-contracts

Start with one command

npx rea-agents setup

Choose your agent, review the planned changes, and approve setup. Native binary analysis can use an existing Hopper, Ghidra, or IDA installation; static JavaScript analysis needs no native analysis engine.

For a first result from an extracted JavaScript application or ASAR:

npx -y rea-agents@latest analyze-javascript-application /absolute/path/to/app --json

See installation and setup for requirements and configuration.

For runtime instrumentation, see the Frida guide.

Task Guides
Inspect native functions, references, or types Native binaries, Go metadata, Rust dependencies, offline ELF layout, recorded crashes
Select a native provider or import format Ghidra semantics, Windows, DOS, raw bytes, MIPS, PSP, NativeAOT, IDA, Kuna, JEB
Analyze JavaScript or Electron artifacts Static analysis, tracing and comparisons, application graph, source recovery
Compare static JavaScript with runtime observations Runtime attribution, reconciliation, Electron observation, Electron fuses
Inspect assemblies, packages, or firmware .NET, Android, Apktool resources, ADB acquisition, Apple, Harmony, firmware, WASM, EVM
Observe or compare a browser scenario CDP observation, scenarios, runtime evidence, historical captures
Serve recorded behavior as an agent environment Agent environments
Trace captured website source Source locations, module traces, script export
Capture and compare a command Process capture
Use CLI/MCP and retain evidence CLI, MCP contracts, agent prompts, obligation ledgers

For development, use testing, client verification, tool design, and releasing. Reconstruction readiness describes a development conformance verifier. The 6.2 migration records that release's compatibility changes; the roadmap tracks future work.
