Module projection 

memstead projection — the binding (projection-promotion) command tree.

The projection is the unit: one versioned binding per source→mem obligation (bundle plan 03-projection-promotion). The tree ships five leaves — brief, init, migrate, advance, enable:

• brief renders a binding’s run-brief — the Markdown prompt an agent consumes — for a canonical binding id <mem>/<stem> (D3/D9), or the next due binding under --all (round-robin + backoff selection).
• init scaffolds a fresh v1 binding non-interactively (D8).
• migrate promotes both legacy generations into v1 bindings (D10): the root-folder scopes|projections|ingests/ layout (gen-1) and the gen-2 four-primitive store (Projection + flat Ingest).
• advance records disposition-gated sync-baseline advances (D7).
• enable adds a missing build / sync / verify operation block to an existing binding (D6 — the remedy a refused mutating op cites).

This tree is the sole binding surface: the retired ingest and pipeline command trees folded in here (ingest brief → projection brief, pipeline migrate → projection migrate’s gen-1 path).

Errors carry PROJECTION_* wire tokens (D12); the missing-workspace path is single-sourced through crate::setup::workspace_not_initialised_error.

Enums

EnableOperationArg

The operation projection enable adds to a binding. Mirror of the binding’s operations block: build is always present (required), so enabling it always refuses as already-enabled; sync / verify are the enableable blocks.

MediumTypeArg

The medium type flag for projection init — the CLI-facing mirror of MediumType (which carries serde, not clap, derives). Decides the capability matrix (D6) that filters the default binding’s operations.
