+- Date: 2026-10-24
+- Provenance: two files explicitly selected by the operator as successfully tested
+- Scope: byte-preserving acquisition and offline XML analysis; no hardware access
+
+The two explicitly supplied files supersede the earlier exclusion only for
+these selected originals. Other unverified local projects remain excluded.
+Raw geometry, names, paths and complete settings remain in PrivateStash.
+Both copied files were verified against their originals with SHA-256.
+See [public manifest](../../evidence/public-lightburn-verified-projects.jsonl).
+
+Both roots are `LightBurnProject`, with `AppVersion="2.1.03"` and
+`FormatVersion="1"`. Process settings occur as direct children of
+`CutSetting`, with numeric strings in a `Value` attribute.
+
+| Artifact ID | Layer type | Raw `frequency` | Raw `QPulseWidth` |
+| --- | --- | ---: | ---: |
+| `sha256-1e1ec8441cc23ee997a6` | Scan | 200000 | absent |
+| `sha256-1e1ec8441cc23ee997a6` | Cut | 80000 | 180 |
+| `sha256-1e1ec8441cc23ee997a6` | Scan | 1000000 | 10 |
+| `sha256-0807d2a2d1613e1aff90` | Scan | 1000000 | 10 |

+| `sha256-0807d2a2d1613e1aff90` | Scan | 1000000 | 10 |
+
+All four Scan settings also have `crossHatch Value="1"`. These are stored
+layer settings, not independent proof of which settings emitted on a machine.
+Successful operation is the operator's statement; it was not replayed here.
+
+## Import implications
+
+This closes the missing operator-verified project serialization evidence gate:
+`frequency` and case-sensitive `QPulseWidth` are now observed in actual
+projects, consistent with the earlier device export findings.
+
+The absent pulse-width field must remain distinguishable from zero or an
+explicit value. Its effective LightBurn default or inheritance is not established
+by this inspection. An importer must preserve absence and require an explicit,
+validated resolution before a MOPA job can become executable.
+
+These raw values do not independently establish units, safe ranges, calibration
+or device identity. The next implementation should use synthetic geometry and
+test explicit unit conversions, field absence and invalid values. It must not
+copy private project geometry into public fixtures or enable hardware access.
+
+The reviewed Windows artifact and manual no-device desktop acceptance remain
+open. ADR 0002 remains Proposed until those gates have also passed.
