trueline 0.1.0.dev0

Spec-Driven Development (SDD) framework for Claude Code users.

trueline

Spec-Driven Development (SDD) framework for Claude Code users: specs and architecture as living documents and source of truth, evolution via spec deltas and ADRs, finalization with a judge-until-convergence loop and a human gate — all driven by an external orchestrator over a headless core.

Status: Milestone 1 (skeleton) implemented — strict schemas, fold-engine with byte-for-byte parity with OpenSpec, ADR log with projected state, derived state machine, cumulative gates, judge-until-convergence loop, headless invocation (SDK/CLI) and the full CLI surface.
