 ## Findings
 
+### Attachments, live check (2026-10-16)
+
+- An image reading "BLUE 42" (`magick`, 400x120) was answered `BLUE 42`,
+  first token at 6.1 s, ctx 1242 / 32768.
+- A two-page PDF, a text page and an image-only page, was answered with
+  facts from both: the text page went inline, the image-only page as a
+  `pdftoppm` render.
+- A page render needs a bound: at `-r 150` a 3000 pt page came out
+  6250x6250 at 171 MB peak (review probe). Renders use `-scale-to 2048`.
+- tesseract is installed with no language data, so OCR is the model's
+  vision, not tesseract.
+- A Unix socket path is limited to 108 bytes: a test socket under a deep
+  scratch directory fails with `AF_UNIX path too long`.
