A window that opens before a counter existed reports that counter as though it had been measured throughout. The reader cannot tell "zero because nothing happened" from "zero because nobody was counting yet", and — worse — cannot tell a partial count from a complete one. That middle case yields a plausible FRACTION rather than an obvious zero, which is what makes it dangerous. It is not hypothetical. A 7-day window opened while the ranked rule surfacing recorders were four days old produced an apparent 64% write loss, which survived a code review, four ruled-out alternative causes and a five-step milestone before an identity check falsified it in one read. Every counter block now carries `complete_from` and `covers_window`. THE GRAIN IS THE SOURCE. retrieval_logs accumulates for months, so a per-table earliest row says months for every source it holds — including an arm added days ago whose counter means something else entirely. The old source would vouch for the young one, which is the exact reading this prevents. A SECTION TAKES ITS LATEST CONTRIBUTOR, NOT ITS EARLIEST. A figure summing several sources is complete only once every one of them was being written, so "*" is a max. Using min would reproduce the original error in miniature. `covers_window` is null, never false, when nothing was ever recorded: "no measurement" is not "partial measurement" — the null convention #3497 established for `suppression`, one level up. Also corrects a stale claim in the tool docstring: it still taught readers that write_path_rule "has never once declined to fire" (#3311). That was the arm writing its retrieval_logs row only on calls that found something; #3497 fixed it, and the arm declines the large majority of its calls. _complete_from takes the caller's session rather than opening its own, departing from the services canon (#2860) because it runs inside an existing block; to be recorded against the ledger once it ingests.

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.
