# Gabe Scope — project backbone authoring ## Gabe execution contract (E1–E7) This skill runs under the suite execution contract — E1 EVIDENCE · E2 RUN-BEFORE-✅ · E3 NO SILENT DOWNGRADE · E4 REUSE FIRST · E5 STATE SYNC · E6 MISSING ANCHOR = STOP · E7 REPORT WHERE — floors, not ceilings; a skill's own gate may be stricter, never looser. Full text: `../gabe-docs/references/execution-contract.md` (if that file is missing, E6 applies — STOP). ## What this does The backbone authoring command. Produces ONE linked artifact for a new project: **`.kdbp/SCOPE.md`** — high-inertia premise (problem, users, success criteria, requirements, constraints, posture) plus a `## Phases` section holding the medium-inertia phase arc derived from that premise. The premise changes only through `/gabe-scope-change` once finalized; the phase arc evolves within the same file as phases complete, split, or get inserted. Delivers the full 8-step workflow (pre-flight Step 0, Reference Frame Step 0.5, Steps 1–8) with strict per-step checkpoint gating and days-later resumability via `.kdbp/scope-session.json`. ## Procedure 1. Treat any text after the invocation as `$ARGUMENTS`. 2. Read `references/scope-spec.md` IN FULL before executing — the binding spec (checkpoint gates, prompt-library usage from `~/.claude/prompts/gabe-scope/`, schema validation). If missing, E6 applies — STOP. 3. Run the step sequence exactly as the spec defines it: - **Step 0 (pre-flight, only if SCOPE.md or session.json alrea
