## Rules For This Pass

- Originals remain untouched in `intake/L-Archive/`.
- Clean isolated stills are preferred over older context shots when mapping artifact candidates.
- Screenshots, videos, packaging evidence, and tool/process context are separated so they do not become part records by accident.
- Labels remain provisional until measured against the CaseLabs chassis, Mercury S8 manual, or confirmed source references.

## Candidate Artifact Series

| ID | File span | Working label | Interpretation | Confidence | Notes |
| --- | --- | --- | --- | --- | --- |
| LA-S34 | `IMG_1642`-`IMG_1643`; `IMG_1645`-`IMG_1658` | CaseLabs XL-ATX motherboard tray inside rail system, likely STH-10 vertical wall | Large white XL-ATX motherboard tray sitting inside the rail system of what is presumed to be the old STH-10 vertical wall | High | Human-corrected from pass 02 review. `IMG_1644` is explicitly excluded and split into LA-S34A. |
| LA-S34A | `IMG_1644` | CaseLabs STH-10 Magnum 10-slot rear I/O panel | White rear I/O expansion-slot panel for the STH-10 Magnum | High | Human-corrected from pass 02 review; not part of the XL-ATX motherboard tray series. |
| LA-S35 | `IMG_1659`-`IMG_1666` | EK-Multioption RES X2 - 250 Advanced, clean isolated run | Cylindrical reservoir assembly with black acetal end caps and brass fittings | High | Human-corrected span from pass 02 sheet 2. Likely same or matching reservoir as LA-S01 and LA-S27. Good views of top, bottom, tube, and port layout. |
| LA-S36 | `IMG_1700` | Workstation context | Photo workstation / bench context before the pedestal panel run | Low | Context only; not an artifact record. |
| LA-S37 | `IMG_1701`-`IMG_1709` | CaseLabs STH-10 Magnum 10-slot rear I/O backplate | White 10-slot rear I/O/backplate panel | High | Human-corrected from pass 02 sheet 2. Same identified part family as LA-S34A. |
| LA-S38 | `IMG_1710`-`IMG_1715` | CaseLabs extra-long PSU support bracket | PSU support bracket for very long power supplies | High | Human-corrected from pass 02 sheet 2. |
| LA-S39 | `IMG_1716`-`IMG_1722` | CaseLabs pedestal front panel | Front panel of the pedestal | High | Human-corrected from pass 02 sheet 3. |
| LA-S40 | `IMG_1723`-`IMG_1726` | CaseLabs pedestal rear panel, PSU cutout back | First pedestal rear panel; back with power-supply cutout | High | Human-corrected from pass 02 sheet 3. Matthew has two pedestal backs; this is the first back. |
| LA-S41 | `IMG_1727`-`IMG_1730` | CaseLabs pedestal rear panel, dual 120 cutout back | Second pedestal rear panel; back with dual 120 mm cutout | High | Human-corrected from pass 02 sheet 3. |
| LA-S41A | `IMG_1731` | Pedestal front/back pairing context before cleaning | Front and selected back staged together before cleaning | Medium | Context evidence for the front/back set Matthew intends to use together. |
| LA-S42 | `IMG_1732`-`IMG_1739` | EK-Multioption RES X2 - 250 Advanced, final isolated run | Cylindrical reservoir assembly with clean full-length and end-cap detail views | High | Human-corrected from pass 02 sheet 3. Likely same object as LA-S35, LA-S27, and LA-S01 unless human pass confirms multiple matching reservoirs. |
| LA-S43 | `IMG_1616`-`IMG_1621` | OMS-882 voice recorder artifact/provenance set | OMS-882 voice recorder and related package/process evidence | High | Human-corrected from stragglers sheet. All straggler-sheet items except the final `IMG_1641` frame belong to this artifact set. |

## Reference / Context / Quarantine

| File span | Disposition | Reason |
| --- | --- | --- |
| `IMG_1641` | context_video | Blurry video thumbnail of a panel/object in hand. Use only if the video captures handling details not visible in stills. |
| `IMG_1671`-`IMG_1675` | manuals_staging | Phone screenshots of L'Archive / Hang On To Each Other pages and CaseLabs panel reference imagery. Kept, but not part of artifact intake yet; copied to `intake/SLUSH/manuals/`. |

## Immediate Questions For Human Pass

1. Do `IMG_1659`-`IMG_1666` and `IMG_1732`-`IMG_1739` show the same reservoir, or two matching EK reservoirs?
2. Should the OMS-882 voice recorder record include all `IMG_1616`-`IMG_1621` provenance/process frames, or only final device-facing stills?
3. Should `IMG_1671`-`IMG_1675` later move from `intake/SLUSH/manuals/` into a public source-reference/manuals lane?

## Source Notes

- This pass improves the object-level evidence quality over pass 01 by adding isolated views, clearer scale references, and fewer mixed layout shots.
- Matthew corrected pass 02 sheet 1 on 2026-06-14: `IMG_1642`-`IMG_1658`, minus `IMG_1644`, are the XL-ATX motherboard tray inside the rail system; `IMG_1644` is the STH-10 Magnum 10-slot rear I/O panel; `IMG_1659`-`IMG_1665` are the EK Multioption RES.
- Matthew corrected pass 02 sheet 2 on 2026-06-14: `IMG_1666` belongs with the EK Multioption RES; `IMG_1667` and `IMG_1668` were deleted from this triage map. Raw originals remain untouched pending explicit raw-file deletion.
- Matthew corrected pass 02 sheet 2 and sheet 3 on 2026-06-14: `IMG_1700` is workstation context; `IMG_1701`-`IMG_1709` are the 10-slot backplate; `IMG_1710`-`IMG_1715` are the extra-long PSU support bracket; `IMG_1716`-`IMG_1722` are the pedestal front; `IMG_1723`-`IMG_1726` are the first pedestal back with PSU cutout; `IMG_1727`-`IMG_1730` are the second pedestal back with dual 120 cutout; `IMG_1731` shows the front/back pairing before cleaning; `IMG_1732`-`IMG_1739` are the EK Multioption RES again.
- Matthew corrected the stragglers sheet on 2026-06-14: `IMG_1616`-`IMG_1621`, excluding the final `IMG_1641` frame, are the OMS-882 voice recorder artifact/provenance set.
- `IMG_1671`-`IMG_1675` are retained as manual/source-reference material but are not artifact intake yet; copies were staged in `intake/SLUSH/manuals/`.
- No originals were renamed or modified.
