Attribution was measured, not inferred: the visual suite was run at the
merge-base `9e5fbd1` in a detached checkout (13 failed / 117 passed) and the
`-actual.png` each run produced was compared by SHA-256 against HEAD's. For
13 of the 18 failures the rendered bytes at HEAD and at the merge-base are
identical, so those failures belong to `main`, not here.
Regenerated (all Case-editor surfaces, all grown by the Task 10 Asset panel;
the +293px band was inspected in the new golden and is the "EVIDENCE / 본문에
Asset 삽입" panel):
tech-log-studio-document-edit-360 360x3313 -> 360x3627
tech-log-studio-document-edit-1440 1440x2706 -> 1440x2999
tech-log-studio-case-editor-1440 1440x2706 -> 1440x2999
tech-log-studio-conflict-editor-1440 1440x2706 -> 1440x2999
tech-log-studio-dirty-leave-dialog-1440 1440x2706 -> 1440x2999
`--update-snapshots` was restricted to those five tests with `--grep`; a
blanket update would have absorbed the 13 inherited failures and destroyed
the distinction. `test:visual` now reports 13 failed / 117 passed, exactly
the merge-base's set.
Two earlier records are corrected in the spec: the five "pixel-only, not
investigated" failures are all inherited, and `TECH_LOG_STUDIO_DOCUMENT_NEW`
360px was wrongly attributed to the Asset Picker -- it fails at the
merge-base with the identical 28,413 differing pixels.
