Make the §13.3 lever a first-class feature, not experiment-only.
- programme.py: SpaceReq.share (default 1) + has_share, parsed from
patterns.config 'share: N'.
- operators._share_grain: resolve per-code grain from leaf_share_factor
selector — 0 = per-code opt-in (share iff share:N>=2), >=2 = global with
per-code override (share:1 opts OUT, share:N sets grain). _share_rooms
groups per resolved grain.
- End-to-end conf injection without monkeypatch: load_config(overrides=)
merges run-level keys last; driver.search / innerloop.optimise /
NativeEvaluator / _fitness_for thread conf_overrides={leaf_sharing:True}
through both inner-loop and off-tree scorers when sharing is on.
- homemaker-evolve: --leaf-sharing/--no-leaf-sharing + --leaf-share-factor
(env HOMEMAKER_LEAF_SHARING / HOMEMAKER_LEAF_SHARE_FACTOR).
- Example programmes untouched (§13.3/§13.9 stay reproducible). Experiment
load_config monkeypatches updated to accept overrides=.
Tests: grain modes, opt-out, default-OFF parity, load_config overrides,
programme parse, CLI parse. 233 pass. Smoke: harbor 37 vs 95 fails on/off.
