doc-iplan

Purpose

Create an Implementation Plan (IPLAN) — Layer 8 of the SDD flow. An IPLAN bridges SPEC + TDD to source code: declares test-first file order (inherited from TDD), executable bash commands, session progress for stateless executors, and an audit trail from spec to delivered files.

Layer: 8 (final doc layer; downstream is Code). Upstream: SPEC, TDD (per the necessary-upstream contract; the rest of the chain is reachable transitively via SPEC/TDD's own @-tag references).

One IPLAN per SPEC component (matching its TDD). Bugfixes with no new functionality use a temporary plan in docs/08_IPLAN/tmp/ instead.
