## What 2718lab-devkit does, in the publisher's words

2718lab DevKit is a Codex-first engineering toolkit: a local, stdio-only MCP runtime for bounded project indexing, Atlas evidence, Relay lifecycle coordination, and deterministic Fast Lane planning, plus a compact Skill bundle of reference manuals. This repository carries the versioned v1.2.1 package. The checked-in manifest and allowlist define the executable runtime surface; the manual map, install, build, and verification sections below describe the supported workflow.

The public Python compiler and CLI retain the deliberately fail-closed team-efficiency/fast-lane-plan-v1 preview. For new work, prepare fast-lane-request-v2 with prepare_model_neutral_fast_lane_request; MCP fastlane_compile then resolves the workspace/snapshot selectors through its local RuntimeRoot and returns a verified team-efficiency/fast-lane-plan-v3. Its assignments describe requirements and leave model selection to the coordinator using current Codex tool metadata. Every descriptor remains plan_only: it never dispatches, claims a lease, creates a worktree, or authorizes execution. Request-v1/plan-v2 stays available for exact legacy replay.
