Extended per-layout metadata for the manifest.

Carries richer operational metadata that Hopper Manager, CLI, and migration tooling use beyond what LayoutManifest provides.

Fields

name: &'static str

Layout name (must match corresponding LayoutManifest.name).

segment_roles: &'static [&'static str]

Segment role descriptors (for segmented accounts).

append_safe: bool

Whether append-only changes to this layout are always safe.

migration_required: bool

Whether changes require an explicit migration instruction.

rebuildable: bool

Whether derived data (index/cache segments) can be rebuilt from core.

policy_pack: &'static str

Policy pack name that governs writes to this layout.

invariant_pack: &'static [&'static str]

Invariant pack names that must hold for this layout.

receipt_profile: &'static str

Receipt profile name for mutations on this layout.

phase_requirements: &'static [&'static str]

Execution phases this layout participates in.

trust_profile: &'static str

Trust profile label (e.g. “verified”, “trusted”, “unchecked”).

manager_hints: &'static [&'static str]

Hints for Hopper Manager rendering.
