Cache distributor EOL/NRND/RoHS without inventing replacements, flag catalogued errata pull-ups only, and store layout_rules with a closed kind enum so millimetres stay null unless the datasheet stated a number. Co-authored-by: Cursor <cursoragent@cursor.com>

"""layout_rules from datasheet — closed kind enum, no invented millimetres.

|
|
|
Favor: decoupling_proximity with a numeric max_distance_mm and source_page;
|
|
empty list is valid (explicit skip).
|
|
Against: unknown kind is rejected; a non-numeric distance becomes null
|
|
(not a guessed JEDEC 3 mm); thermal_via without min_via_count is kept
|
|
but distance stays unset.
