Struct ProjectionPlacementSpec 

pub struct ProjectionPlacementSpec {
    pub root: Option<String>,
    pub dir_template: Option<String>,
}

GH #27 (follow-up to #23) — Blueprint-declared override of the mlua-swarm core crate’s placement resolver (mlua_swarm::core::projection_placement::ProjectionPlacement), which decides where a Step’s materialized OUTPUT file (submit-time sink, server read-back, and spawn-time ctx_projection pointer — the “3 path” convergence point) is written on disk. Both fields are independently optional and validated (dir_template) at Compiler::compile time — see that resolver’s from_spec doc for the full rejection rules.

Fields

root: Option<String>

Which of the spawn-time work_dir / project_root to prefer as the materialize root, falling back to the other when the preferred one is absent. "work_dir" (default, current byte-compat behavior) | "project_root". None = the default ("work_dir").

dir_template: Option<String>

Target directory template, relative to the resolved root, with a {task_id} placeholder substituted at materialize time. None = the default ("workspace/tasks/{task_id}/ctx", current byte-compat behavior). Must be non-empty, contain the {task_id} placeholder, stay relative, and not contain any .. path segment — rejected at Compiler::compile time otherwise.
