Current node showed "negative prompt" only on values from a workflow. A material's blocks carried no role, and when a picture and a workflow held the same text the merged card kept the picture's empty one, so a negative prompt could be offered to a positive box with nothing to say so.
- api/materials.py works the role out by what the prompt was wired to, as the material details already do; it reads the stored workflow, so pictures kept earlier get it too.
- node_parameter_sets.js takes the role from whichever source knows it.

Each saved set for the selected node is a card with the picture made with
its values (or the kept picture it came from) and a line per source: a
workflow's parameter set (with how many pictures it made, Open shows that
set), a kept picture (See it), or saved here, with the day. Changes are
drawn: numbers as two bars with an arrow, choices as old -> new; what stays
says why; Show all lists every value. Compare opens the whole workflow
against the canvas. With two sets or more, a side-by-side table (picture on
top of each column, changed values marked, Use N under each).
Backend: materials/by_node_type tells each record's origin, kept picture and
preview; parameters/by_node_type gives each set's signature; new GET
/anomalous/parameter_pictures counts the pictures of many sets in one pass,
reading each picture's signature once per file version.

tests/ (Python backend tests, .mjs frontend rule tests) is no longer
ignored. tools/run_tests.mjs runs the structure check, every
tests/*.mjs and the Python tests with $PYTHON, the portable
python_embeded or python. docs/guides/testing.md says how to run and
write them; README links it. Developer notes no longer point at 18 test
files that were removed earlier (AGENTS.md table, backend, frontend and
update-guide notes).
