`list_rule_versions` / `get_rule_version` in the rulebooks service, a pair of REST routes beside the note-version ones, and an MCP `rule_history` tool. The ACL-scoped reads live in services/rulebooks.py rather than in services/rule_versions.py because rulebooks already imports rule_versions for the write path and the reverse would be a cycle. It is also the honest split: rule_versions owns what a version IS, rulebooks owns who may read one. Scoping is through the RULE, never the version's user_id, and both directions of that mistake are now pinned by tests. That column is the ACTOR — scoping by it would hand someone the snapshots they personally wrote on a rule that has since moved out of their reach, and would hide from the rule's owner every edit anyone else made. `get_rule_version` takes the rule id as well as the version id so the ownership check and the fetch agree about which rule is in play; the test for that uses a second rule the caller genuinely owns, because a nonexistent id would pass on the ownership check alone and prove nothing. An unreadable rule returns None, not an empty list. The two mean different things — "not your rule" versus "never reworded" — and the MCP tool keeps them apart: None raises, empty says so in band. THE DIFF QUESTION, ANSWERED — and the task's premise was half wrong. It says "notes have DiffView.vue and a diff endpoint already". The component exists and is reusable as-is: it takes `DiffLine[]` and nothing note-shaped, so step 4 can render a rule diff with it unchanged. The ENDPOINT does not exist — diffs are computed client-side by `computeDiff` in useAssist.ts. So no diff route is needed here, and none was written. For the MCP door the answer is different again: an agent has no client to compute a diff, but it also does not need one. Each entry holds the text the edit REPLACED, so "what did this say before the most recent change?" is the first entry, and the text that change produced is the rule as it stands. The docstring says so, and a test pins that sentence — read the other way round, every diff comes out backwards. No restore, per the task. Putting an old wording back goes through update_rule, which snapshots what it replaces, so the undo stays visible like any other edit. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>
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.
