//! The tier list's "Adopt" action.

/// The tier list's "Adopt" action: switches a pinned tier over to the meet
/// instruction the source file actually stated for it
/// (`ConstraintTier::imported_meet`), through `Edit::SetConstraint` like any other
/// edit. A silent no-op if the tier has nothing to adopt or the index is stale:
/// `EditorView` only shows the button when `imported_meet_text` is non-empty, so this
/// only guards a race with a concurrent edit.
///
/// Calls `refresh_editor_panel_stale` (with `dirty = {index}`), not `refresh_all`'s
/// real re-solve -- deliberately the one exception to "Solve on explicit action,
/// not on every edit" that it would otherwise be: adopting a suggested meet isn't
/// really a new edit whose result is unknown, since the value being adopted is
/// exactly what the tier already showed after the design's last real solve, so
/// paying the whole-schedule solve cost to re-confirm one already-known value
/// would be a bigger hammer than it needs. `refresh_editor_panel_stale` pushes the
/// immediate UI update from the CACHED last solve (which reads every OTHER row
/// from that cache -- see `push_stale_content`'s own doc comment) and lets the
/// background dirty-set replan confirm it via `resolve_dirty` instead, the same
/// approach `callbacks::tier_actions::setup_pin_to_mast_callback` uses for its own
/// per-row "Pin" action. "Solve, Adopt, and it says not solved again" cannot
/// happen: `refresh_editor_panel_stale` reads the actual cached solve rather than
/// a fixed "Not solved" banner for the untouched rows.
