Purpose

Create a Technical Specification (SPEC) — Layer 6 of the SDD flow. A SPEC is the implementation-ready, C4-L3 (Component) contract for a single software component: its interfaces, data models, and behavior — written before any downstream test or code.

Layer: 6 — the unified specification. A SPEC subsumes what older revisions split into component/data/ux/risk/process specs; there is now one SPEC artifact per component. Upstream: EARS, BDD, ADR (per the necessary-upstream contract; ADR is the primary source. Upstream PRD/BRD lineage is reachable transitively via the @-tag chain). Downstream: TDD → IPLAN → Code.
