Unreleased

Changed

• Rebrand: rmr → morel (MOdality-REcommended Links).
• Single-word domain naming applied throughout; implementation visibility follows the public/_semi_private convention in docs/engineering.md.
• Module structure reorganized around explicit domain boundaries (core → data → model → train → eval → app → cli).
• Strict layering enforced by tests/unit/test_architecture.py (stdlib ast import-graph check).
• Strict mypy mode for morel/.

Added

• morel.core runtime primitives: Config, seed, Device, Log, Fidelity registry.
• morel.data lifecycle: acquire, validate, extract, build, mask, store, Manifest.
• morel.graph polymorphism: Graph, Bipartite, Item, Subgraph, Laplace.
• morel.retrieve correctness fixes: iterative ACS, best-improvement MAGE, sorted boundary.
• morel.encode, morel.route, morel.codebook, morel.complete, morel.recommend.
• morel.pipeline end-to-end orchestration.
• morel.train, morel.eval, morel.app, morel.cli, morel.serve.

Removed

• .pre-commit-config.yaml (checks now enforced in CI).
• rmr/ package (legacy stub remains for one release cycle).
