ADR-0001 — pnpm + Turborepo monorepo

• Status: Accepted
• Date: 2026-06-02

Context

Nine tools share a crawl/parse/score pipeline and an MCP middleware layer. Building them as separate repos would duplicate the engines and fork their fixes.

Decision

Single monorepo using pnpm workspaces (content-addressed store, strict deps, workspace:* linking) and Turborepo (task graph, caching, ^build ordering). Shared engines live in packages/, tools in apps/.

Consequences

• Reuse layer is built once; second audit tool is days not weeks.
• One toolchain, one CI, atomic cross-cutting changes.
• Workspace globs (packages/*, apps/*) let parallel agents add packages without touching root files.
• Cost: contributors learn the workspace model; tooling (turbo) added to the chain.
