# Local LightBurn settings acquisition
|
|
|
|
- Date: 2026-10-24
|
|
- Scope: offline acquisition of the closed application's local settings directory
|
|
- Hardware access: none; connection status was not tested
|
|
|
|
## Evidence and integrity
|
|
|
|
The complete settings directory was archived in PrivateStash. Its 255 files
|
|
include 250 preference backups, current and previous settings, two JSON files
|
|
and a material-test preset. Archive members were checked against source SHA-256
|
|
digests before and after copying; ZIP integrity and the final archive digest
|
|
were also checked. The source files were not modified.
|
|
|
|
The archive SHA-256 is
|
|
`d64320d13d8a543820ab1dd25e42791ac9a6faff89b7cb07aadbd707e9a3ca39`.
|
|
The current settings member SHA-256 is
|
|
`0b1f3496e9838788cd1e8469a2ddae279a7d0dc872767768f77fbeeaff4603e2`.
|
|
The public artifact contract is recorded in
|
|
[`public-lightburn-local-settings.jsonl`](../../evidence/public-lightburn-local-settings.jsonl).
|
|
Raw preferences, backup contents and exact local paths remain private.
|
|
|
|
## Observations
|
|
|
|
The current settings file contains JSON despite its INI extension. It has four
|
|
device records. Exactly one uses `LibUSB` with a 110 x 110 mm work area. That
|
|
profile enables `Laser_QPulseWidthEnabled` and `RequireFrameBeforeStart`.
|
|
The global cut list has 60 entries, including 35 with `frequency` and 25 with
|
|
`QPulseWidth`. These counts agree with the earlier export analysis; they do
|
|
not establish that every profile field is unchanged or that global recipes
|
|
belong to a particular machine.
|
|
|
|
The operator separately confirmed the installed lens as **110 mm**. This is
|
|
an operator statement, not an independent verification of the lens label,
|
|
calibration or correction profile. A stored connection type does not establish
|
|
that a controller is connected or works.
|
|
|
|
## Excluded project files and remaining gates
|
|
|
|
The operator stated that the locally discovered project candidates are
|
|
unverified test files and instructed us not to use them. Nine temporary copies
|
|
were removed from this acquisition before analysis or commit. Their originals
|
|
were unchanged; no project content was analyzed or retained as evidence.
|
|
|
|
This collection closes the missing closed-application settings snapshot. The
|
|
gate was subsequently closed by three separately supplied, operator-verified
|
|
projects plus the running LightBurn 2.1.03 UI. The excluded candidates remain
|
|
unverified and are still not evidence. The resulting vector import mapping
|
|
stays disabled and review-gated; it is not executable machine authorization.
|
|
|
|
The reviewed Windows artifact and manual no-device desktop acceptance also
|
|
remain outstanding. No controller, USB endpoint, framing, motion or laser
|
|
operation was performed or authorized by this collection.
