REPORT — agent: gofmt clean-up and gate (2026-10-19, second day brief)

No release. Agent 0.160.0 stays the newest release; the operator vouched it on 2026-10-19 (08:24).

1edfd8e — gofmt -w on the 14 files that were not gofmt-clean. Formatting only; go build, go vet and go test ./... green before the commit.
scripts/gofmt_gate.py — every Go file under cmd/ and internal/ is gofmt-clean (R-1160), the controller's gofmt_gate.py shape: exit 1 names each file, a missing gofmt is INCONCLUSIVE on a dev machine and NOT CHECKED (out loud) in CI. Registered in agent_gates.py (fast set, so the pre-push hook runs it).
Decoys (scripts/test_gate_decoys.py, gofmt_cases): an unformatted file in a scratch copy → rc 1 naming it; the formatted twin → rc 0; no Go + CI → rc 0 "NOT CHECKED in CI"; no Go on a dev machine → rc 2. Red-proof: with the conviction switched off, the FACT case reported rc=0 expected 1 - LIVE HOLE. Restored; agent_gates.py all OK.
