Step 2 of #4251. A System's `description` is a charter — several hundred words saying what belongs in that area and what does not — and it is the answer to "which part of this codebase does X live in". There was no semantic path to one: `list_systems` enumerates, and `search(system_id=…)` uses a System as a FILTER over notes. So a System could narrow a search and could never be the answer to one, and an agent asking where a record belonged had to read every charter or guess. ITS OWN SEARCH, not a `content_type` over notes, for the reason note 3163 gives about milestones: the row could be shared, the search cannot. A charter competing with the whole note corpus for one top-k is outranked by the records filed under it — the right answer crowded out by its own contents — and "where does this belong?" is a different question from "what prior art is there?", which a caller asking one should not have to read past answers to. So `system_embeddings` (0107) joins note_, rule_ and milestone_embeddings as the fourth sibling, with `system_document`, `upsert_system_embedding`, `semantic_search_systems`, a startup backfill and `search(content_type= "system")`. Scoped like milestones: with a project_id, that project's Systems if the caller can read the project (rule 78); without one, the caller's own. Archived Systems are excluded — an archived area is one the operator has said is no longer where things go, which is exactly the question being asked. `system_document` is the plainest of the four shapes on purpose. A charter is already written as the thing this search has to match, in the words someone asking would use — so there is no trigger to synthesise as `rule_document` must, and no second record to gather as `task_document` must. The stored charter IS the sharp document, the way a snippet's is. `color`, `status` and `order_index` stay out: presentation and bookkeeping, and a vector carrying them would be answering a question nobody asks of a charter. The search publishes `report["best_chunk"]` from the start rather than being retrofitted, which is what #4251 asked of any fourth search. It matters more here than anywhere: a charter runs long and a result shows its NAME, so a match on the paragraph that actually decides where a record belongs would otherwise be previewed by two words that cannot say. The id that comes back is the one `system_id`, `system_ids` and `list_system_records` already take, so the answer to "where does this belong?" is directly usable as "show me what is there" and as "file it here". `embed_system` sits beside `notes.embed_note` at the service for #2056's reason — every door gets it by construction. Not called on delete: that is a soft delete and the search joins through `System`, so the vectors are already unreachable, and leaving them means a restore is findable again immediately. `system_embeddings` is declared in backup's `_NOT_INCLUDED` as derived, beside its three siblings.
