meta-dream-crosstreelisted

# meta-dream-crosstree The cross-project dream. `bitranox:meta-dream-tree` tidies ONE knowledge tree, TREE-WIDE - every level under that anchor, so it already sees sibling projects sharing it - and is the frequent, cheap pass; **meta-dream-crosstree is the occasional, EXPENSIVE pass that reads across ALL project stores - and it is the ONLY dream whose territory spans INDEPENDENT KNOWLEDGE TREES** (a machine can carry several tree tops; the project dream never crosses them). Cascade only flows down one ancestor chain, so knowledge filed in a sibling project or another tree is invisible elsewhere; this skill bridges that. Tree discovery runs over the configured `discovery_roots` (`tree-top` / `ensure-all-trees` locate the tops). It builds on `bitranox:meta-self-improve` (altitude logic, the upstream-PR loop, `reconcile_memory_index.py` - home: `<plugin>/skills/meta-self-improve/`, launch via `hooks/run-python.sh`) and delegates inbound gather to `bitranox:meta-collect-knowledge`; follow those for the primitives. Do not duplicate per-project consolidation here - run meta-dream-tree for that first if a project's own store is messy. **It must SHRINK noise, never add it**, and it moves knowledge ONLY by lift-or-copy - **NEVER a cross-tree reference** (a sideways pointer dangles when the other tree is deleted). ## Mode Read the mode per `bitranox:meta-dream-tree` -> references/dream-core.md (propose / auto / off - the knob semantics live ONLY there); `off` skips this skill entir
