i2r-gsd-projection-mode

Owned by: i2r.py assemble + i2r_render.py ($0, no LLM). Consumed by: i2r-orchestrator (assemble step), i2r-completeness-critic (Reader Test Gate — CONTRACT §11).

Output: the complete out/ Markdown package (all 11 documents + decisions/ADR-*.md). Internal machine artifacts (internal/requirements.json, internal/traceability-matrix.json, etc.) are deterministic projections of the stage JSONs — they are NOT primary reading artifacts.

What this mode documents

This mode is the authoritative shape reference for everything i2r.py assemble writes under out/. i2r_render.py is a pure function: it takes already-loaded stage data + lang and returns {filename: content} strings. i2r.py owns file I/O. The Markdown rendering is independently testable and < 800 lines.
