fut::squad_projection is the ONE projector for every squad read shape.
project_squad(canonical squad + Fresh extension + owned items) -> the FIFA
17 squad wire object; user_mass_info_squad and squad_list are envelope-only
wrappers over the same output (no per-endpoint domain model).
Design guarantees exercised by tests:
- purity / no N+1: consumes a host-assembled input (read_squad_with_ext +
one batch owned-cards fetch + in-memory card defs); no per-slot lookup
- shared shaper: every occupied slot is shaped by fut::item::shape_item,
so squad items and /club items cannot drift
- Fresh -> full projection; Stale -> never applied (verdict surfaced);
Missing -> explicit, never fabricated
- captain projects as the resolved WIRE id (never resourceId); index and
formation round-trip verbatim; kit follows the player; two owned copies
of one definition stay distinct
Adds committed sanitized fixtures decoded from the squad session capture
(swap, f433, persisted userMassInfo.squad read, squad/list) and
tests/squad_projection.rs: baseline / swap / formation-change / persisted
read-after-write round-trips asserted by ownership class (canonical,
extension, shadow, derived identity), plus one-projector no-divergence.
