# H2 — labelled supervisor harness recording

Before [701e13c](https://git.cafe/pingdotgg/t3code/commit/701e13cebb040d8433cd9aefb803ddd0d58c41d6); after [37441e9](https://git.cafe/pingdotgg/t3code/commit/37441e905194b062345c76d81caacd00d77ef5e5).

Environment: Linux x86_64 fs-33; labelled harness of the real supervisor module at the column SHA, synthetic Connectivity/Deferred driver, Effect TestClock; xterm under headless-desktop/Xvfb, DejaVu Sans Mono15pt,117×38 cells, ffmpeg x11grab10fps1440×1000; no browser/device emulation; DPR1; OS font scale100%; dark terminal. Live checkpoint stdin handshake paces readable output without advancing logical time; videos are executions, not transcript playback.

Start raw offline with preparing or synchronizing suspended. Base parks until online; head starts immediately. Emit online during first stalled attempt: neither restarts it. Advance logical15s setup or90s synchronization timeout, observe backoff; advance2s to successful replacement. These are logical TestClock advances, not measured wall-clock waits. No immediate-online-restart claim.

No app UI exists for these internal states. These are clearly labelled recordings of the actual supervisor, not an invented status UI. No static before/after scene is claimed; Diff0/DiffT not applicable under the matrix.
