feat(retrieval): a System's charter becomes an answer, not just a filter (#4251)
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.

Fabled Scribe

A self-hosted work system-of-record for software projects, built to be driven by Claude Code. Notes, tasks, issues, projects, milestones, rules, and stored processes — reachable from Claude via a built-in MCP endpoint and a bundled Claude Code plugin, with a clean web UI for humans. No in-app LLM; Claude is the sole assistant.

Features

Notes and tasks with a Markdown editor, sub-tasks, milestones, issues, and kanban project workspaces. Stored processes, an engineering rulebook system (with an inception step that decides what each project inherits), and semantic search with proactive knowledge-injection into Claude's context. A knowledge graph, per-user/group sharing, and a built-in MCP server (/mcp) plus a bundled Claude Code plugin so Claude can record and recall your work directly.

Quick Start

Prerequisites: Docker and Docker Compose. No GPU or local model needed — Claude is the sole assistant, reached over MCP.

Download docker-compose.quickstart.yml from this repo, then:

# Optional but recommended — set a secret key
export SECRET_KEY=your-random-secret-here

docker compose -f docker-compose.quickstart.yml up -d

Open http://localhost:5000. The first user to register becomes admin. To connect Claude, create an API key under Settings → API Keys and install the Claude Code plugin — see API Keys & MCP.

Development: To build from source, see Development.
