Run the governance gate

<!-- sflow-copilot-pause -->

Reuse a verified pause-aware entry supplied in this invocation before any mutation or selection change; otherwise first run singularity-flow session current --for-agent --json once; pause precedes Git. If paused: native Copilot, only /sf-pause off, never resume implicitly. Reuse binding/personalization.replyName; fresh operation checks/consent remain required.

<!-- sflow-output-contract: deterministic-mutation -->

Output contract: Let the CLI validate and mutate state; preserve its exact result, warnings, publication status, artifacts, and next actions. Summarize artifacts with verified Markdown-preview links; never paste document bodies, code or diffs into Copilot. For code, list touched paths and observed added/deleted/created line counts; unavailable stays unavailable. Use existing evidence, not extra calls solely for display. Summaries, links and opened previews are not human review or approval. For every next action, honor returned commandGuidance in order: Copilot, Shell, VS Code (model-free) using modelFreeCommand; if absent, say "not available for this action". Missing Copilot: "no verified equivalent". Never invent routes. On a refusal read remediationPlan: run its first read-only step once and follow context.strategy; never retry an unchanged condition or edit an earlier phase to clear it. One returned automatic plan-hash action (such as sync) may run once, then re-enter once. Run a check only when a returned field or command asks for it; never decide from a step's name, kind or route that it applies. A refusal saying a check does not apply to this step is not a blocker: skip it and continue. Act on a result's act first: its state, do routes and any ask. A bounded result names agentOutput.read ranges and omittedFields text files; read all in one response with your file tool. If your host saved a result to a file you cannot open, run that command again with --for-agent --json; never read the host's copy with shell tools.

<!-- sflow-execution-boundary -->

Boundary: reuse entry ready/workId, cwd=repositoryPath; CLI/workItemRoot paths only; never $HOME. No duplicate lookup. Use exact CLI-returned paths. repositoryPath is command cwd, not a prefix for absolute file paths. Never rebase paths or strip .git/worktrees. Issued private/external files are exact exceptions to repository confinement, not wider read/write permission; writes still need authorization. Resolve relative paths only against their declared base. On failure, preserve the path and error; never search or recreate it.

1. Run singularity-flow gate $ARGUMENTS exactly once.
2. Preserve every configuration, artifact, approval, traceability, conformance, protected-path, quality-command, and remote-state finding.
3. Distinguish a failed gate from a command crash and show the exact remediation supplied by the engine.
4. Do not edit lifecycle state, waive checks, approve, retry repeatedly, or claim merge readiness unless the terminal gate passes.
