One-time, mechanical reformat — no functional changes. The tree was not rustfmt-clean (~1800 hunks across ~100 files); this brings it to stock `cargo fmt` defaults so a `cargo fmt --check` CI gate can follow. Behaviour-preserving: 2509 pass / 0 fail / 1 ignored (unchanged baseline), clippy clean. A .git-blame-ignore-revs entry follows so `git blame` skips this commit.

//! Matrix coverage for `drop relationship (endpoints | name)`
|
|
//! (ADR-0013).
|
|
//!
|
|
//! Two selector forms:
|
|
//! - by endpoints: `drop relationship from P.c to C.c`
|
|
//! - by name: `drop relationship <name>`
|
|
//!
|
|
//! Handoff-12 §2.2 noted the qualified-column slots
|
|
//! (`from T.col`) don't narrow to T's columns. The fix lands
|
|
//! alongside the matrix where the test asserts narrowing.
