P4 Workbench
Bench controls in the browser.
For the firmware engineer who still wants a hand on the supply. Set voltages, load a rail, toggle a GPIO, read a thermocouple, flash a target over J-Link, and open the serial console, all against the same nets your scripts use.

Merges not checked on hardware
A merge counts as checked when this product's suite ran tests on that exact commit after passing the connection pre-check, or on a push that included it. In All products, a merge that touches shared code is counted once for each product it triggers. Two pull requests merged in separate pushes seconds apart can show the first as not checked even though its code ran in the second's run.

Real FW bugs caught
Failures that were resolved by a newer commit, where the test harness blamed the device, the failing commit changed firmware, and the fix changed firmware and not the test harness.

P4.1
Pick a box, get its bench
Choose any online box and its nets appear as widgets on a bench you can arrange, resize, and save once for the whole team.
P4.2
The instruments you use
Power supplies, battery simulators, e-loads, GPIO, ADC, DAC, thermocouples, watt meters, energy analyzers, I2C, SPI, USB hubs, debug probes, UART, and webcams.
P4.3
Nets, not addresses
Every control targets a named Lager net, so the browser drives the same abstraction as your scripts. Swap the instrument, keep the net.
P4.4
Flash and talk to the target
Load a .hex, .elf, or .bin over the debug probe, then open the UART console in the dock, pick a baud rate, and send lines to the target.
P4.5
Every command, logged
Each widget shows its last command. The Log tab in the dock keeps every command with a timestamp, filtered by net, with search and copy.
P4.6
Lock the bench while you work
Take the box lock from the toolbar so nobody else drives the bench, and release it when you are done. It is the same lock the Lager CLI sees.
