BRINGUP gains the Phase 4 (stale-gate cluster) record - code-complete,
host-verified, hot-deployable, bench drills listed. LIGHTBURN.md now
describes the job-based armed window: relock at program end, on a
sender change, or after the spindle-off grace (counting even in Hold).
- LIGHTBURN.md: mandatory "Before you cut" safety section; the
walkthrough now reflects the firing machine (dry runs need the
layer output off or M5; live first-cut instructions); the homing
entry documents homing_mode and the gfcloud method; the machine
address is a placeholder.
- README.md: condensed safety section linking the full text and the
regulatory notes.
- INSTALL.md: "Regulatory and legal" section ahead of the install
steps; routine updates route through the panel updater rather than
the installer.
- BRINGUP.md: the release signing key is described as held offline
(no on-disk path); bench address and credential notes removed;
Next-work item 7 corrected (the installer embeds the production
release key); status entry for audit remediation Phases 0-1; the
GATE A kernel drills join the pending image-flash checklist.
- bench scripts: the target host comes from GF_HOST (or argv) instead
of a hardcoded address.
- laser_stream_test.py: per-session controller runs with a hermetic
cooling-verdict publisher; new assertions that every stream
terminates with FIRE clear (including M3 held to stream end) and
that no FIRE bit rides a zero-step gap; a cycle-churn session
exercises the stop/start seams.
Audit findings D-1, D-2, D-3, D-5, D-10, D-12, B-10, and the harness
half of D-4/G-1.
README: replace the stalled REST/GUI roadmap with what the firmware does -
GRBL mode over TCP for LightBurn/UGS/cncjs, optional cloud mode, the web
control panel, cameras, A/B install beside the factory firmware - plus the
supported hardware incl. the 8 MP camera limitation and a real roadmap.
kas/README: xvclk is the board's 24 MHz oscillator; the pin/push rule covers
every source repo; camera and motion sections are hardware-validated, with the
OV8856 caveat spelled out; the device-tree item closes with the control_12v
residue named; forgectrl is the machine-services daemon with two supervised
controllers.
LIGHTBURN.md: drop the pre-first-light status line.
BUILD.md: state the NXP firmware licensing and where the EULA lives on the
machine. The image now installs firmware-imx-lic, so the EULA text ships beside
the VPU/EPDC blobs it covers; a bbappend declares that package at parse time,
which is what makes it installable from an image recipe.
BRINGUP item 2: grbl-mode laser software implemented + bench-verified
without fire (record in the gate list); first light pending.
LIGHTBURN.md: arming/button-press operation, S-max 1000, fire gates.
scripts/bench/laser_stream_test.py: host-side stream-dump contract
verification against the null-sink build.
BRINGUP records the gate as complete with tach-verified results;
LIGHTBURN.md documents the per-layer Air Assist toggle driving the
cut-profile ventilation; fan_test.py joins the bench kit.
