Primitive partagee (SP-4/SP-2/competences) : hashe la sequence ordonnee (action_type, target) d'un parcours en ignorant les champs session-specifiques (node_id, timestamp, coordonnees) -> deux apprentissages du meme parcours = meme signature = base du create-or-update (decision F1). Le target stable peut etre compose avec screen_signature() existante. Test TDD: tests/unit/test_trajectory_signature.py (5 tests, RED->GREEN).

"""TDD — signature de trajectoire (Phase 0 ; primitive partagée SP-4 / SP-2 / compétences).

|
|
|
Propriété centrale : la signature identifie une TRAJECTOIRE (séquence d'actions sur des
|
|
cibles stables). Elle doit être **stable entre sessions** — donc indépendante des champs
|
|
session-spécifiques (IDs de nœuds, timestamps, coordonnées). C'est ce qui rend le
|
|
create-or-update (décision F1) possible : deux apprentissages du même parcours = même id.
