+# Boot-verification CI — wires the aperture-xt16e harness into GitHub Actions
+# on the Mac Mini self-hosted runner (aperture-jar5i).
+#
+# WHY: comms is our bread and butter; the auto-kickoff + hub supervisor fixes
+# (aperture-syepg #37, aperture-256ru #41) are only durable if the boot
+# harness runs automatically. Without CI it runs "when someone remembers".
+#
+# JOBS:
+#   - boot-smoke   (PR-gated, path-filtered): L1 rust unit tests + the three
+#     MCP suites + L2 boot smoke (stub CLIs). Fast, no real API cost.
+#   - nightly-fleet (cron): thundering-herd fleet x5 (races are probabilistic)
+#     + one real-binary L3 run (~2 real turns/night), results.json archived
+#     for time-to-hello SLA drift.
+#
+# RUNNER PREREQS (Mac Mini, tracked on aperture-jar5i): an aperture-scoped
+# self-hosted runner with labels [self-hosted, macOS, arm64, mac-mini], plus
+# `cargo` (rustup) and `tmux` on PATH — both were MISSING at wiring time
+# (node/pnpm/just already present). CI stays red until those land.
+#
+# PATH FILTER: only fires when the launcher / hub / bridge / harness surface
+# changes — the exact files whose regressions the harness catches.
