# Flight Record — Codifying the Preflight Takeoff Gate > A dispatched first-officer flight (CDO seat, via Otto) to codify the preflight checklist as a hard, enforced takeoff gate. Recorded as its own first artifact under the gate it created — the START-gate declaration below is exactly what the new CI check verifies, and this landing is the END gate closing on the same flight. ## Preflight declaration — cleared for takeoff Run before any work; each item observed live this flight, not from cache or memory. - **Clock** — `oddkit_time` succeeded; `server_time` 2026-07-08T17:22:27Z (UTC). Civil date 2026-07-08 (America/New_York). - **Canon** — `https://klappy.dev/page/canon/bootstrap/model-operating-contract` fetched via oddkit and resolved; content hash `ntc39x`. - **Tools** — oddkit (time/get/orient/search/challenge/gate) and GitAuth present; GitAuth minted a live write+workflows token despite zero quota counters (observed, not assumed). - **Tier** — dispatched Opus flight; matches the tier for a canon-governance change. - **Boarded** — read `boarding-pass`, `generic-boarding-pass`, `flight-deck-model`, and the operating contract this flight. Result: all five green → **cleared for takeoff**. ## What flew Codified the five-item preflight as a hard, fail-closed takeoff gate: authoritative tier-1 constraint (`canon/constraints/preflight-checklist-takeoff-gate.md`), a binding section in the operating contract, the gate written into both boarding passes (project + account text), a root `DISPATCH.md` for dispatched flights, a soft mechanical CI check (`scripts/validate-preflight-declaration.py` + `preflight-declaration` job) as the START-gate mirror of recording-as-landing, and governance markers (CHANGELOG 0.43.0 + release note). ## Cross-check / debrief - The dispatch named a `BOARDING.md` tier-check and an existing `recording-as-landing` rule/CI as grounding; neither exists in `main`. Challenged rather than fabricated: grounded the work in the canon that does exist and flagged the naming gap in the PR for reconciliation. (Axiom 1: reality is sovereign; a claim is a debt.) - `oddkit_challenge` (execution) surfaced generic prompts; addressed in the artifact (evidence, comparison to the end gate, retraction conditions) rather than handed back. `oddkit_gate` PASS 2/2 (dod_met, artifacts_present). - Landing: PR #267, assigned klappy, no review requested. ## Landing Recorded as landing. START gate declared above; END gate is this record plus the merged/open PR. Both bounds present → valid flight.
