The remaining bench diagnostics run from forgetest's #bench tab. The tools that also run from a LAN host share scripts/bench/gfbench.py: GF_HOST names a remote machine (host mode, sysfs through ssh, Grbl and forgectrl over the LAN); unset, the tool runs on the board itself (local mode, sysfs directly, everything on 127.0.0.1), which is how the page runs them - with GF_HOST=127.0.0.1, the panel token in GF_TOKEN and their data files under <data>/bench/ (FORGETEST_BENCH_DATA). The helper also reads a machine setting from forgectrl, or from the settings file on the board while forgectrl is stopped. Ported: pwm_sweep / pwm_hold (scope = a takeover; the latch relocked, the write refused if FIRE or LASER_ON reads active), pwm_stream_test (PASS/FAIL exit), flow_characterize, flow_recheck_char, flow_warm_validate and flow_matrix (takeovers: forgectrl owns the thermal hardware, so the page's takeover replaces the tools' own controller stop/restart, whose command line predated the supervisor; results and logs in the bench data directory), flow_sustained, fan_test, temp_calibrate (dry; watch bounded in seconds; the threshold and the coolant conversion from the shared code), flow_escalate_drill (cool_confirm_max_s shortened through forgectrl's settings for the drill and restored; the setting's minimum is the default budget), and live_fire_drills (<drill> [S] [F], all six drills, host from GF_HOST, token from the board). flow_matrix joins the registry. What stays unported cannot run against the machine at all: the two null-sink CI harnesses and the .puls decoder. Runner: a scope tool runs inside the takeover wrapper; the bench environment above is passed to every tool. Tests: test_bench_registry (registry <-> scripts/bench consistency, every ported tool builds its command line, every script compiles, gfbench host/local modes) and the server test (scope tool takeover, the environment reaching the tool). Local mode smoke-run on the bench (temp_calibrate watch, setting, token) from /tmp, removed after. No catalog consequence: bench tools are not image components (dev-only forgetest); the acceptance catalog is unchanged.
