# Present Gate This skill carries the first-officer's captain-facing gate-presentation rendering: the gate-review format template and the assembly rules for filling it. The decide-to-gate and AC-cross-check policy stays always-on in the FO contract; this skill loads at the gate point to render the decision the FO has already made. ## Presentation channels Chat is the default channel. Render the gate template in the current conversation, then hand the captain's semantic decision to `${SPACEDOCK_BIN:-spacedock} gate record ... --decision`. An override changes only where the captain sees the review; gate policy and recorder ownership stay unchanged. A workflow or session may declare one presentation override. Apply this contract: 1. **Probe before side effects.** Run the override's read-only availability and version probe before preparing or launching a room. If the presenter is missing or mismatched, launch nothing, create nothing, mutate nothing, and emit one line naming the install or upgrade remedy and the chat fallback. Then use chat. 2. **Pass one prepared room.** The scaffold owns `request.json`, the canonical `briefing.json`, the bound gate attempt, and fixed provider outputs. Invoke a Subspace override as `/subspace:r gate <gate-room>`. Do not construct provider argv, paths, actor or approver flags, or an association. 3. **Present the complete canonical Briefing.** The override shows the exact question, every Artifact, and every recursively reached Reference at its...
