Milestone 416 step 6. A retrieval floor is a cosine similarity, which only means something inside one embedding model's geometry over documents cut one particular way. Change either and every floor on the install keeps applying while describing nothing — and nothing anywhere says so, because the scores simply come out different and the bar goes on cutting. `CHUNKER_VERSION` already solved this for documents: stamped per row, so the backfill re-embeds precisely what is stale. The same idea, applied to the numbers: - `calibration_stamp()` — embedding model + document shape, one definition. TWO fields, never a fused string (rule 149): a mismatch has to say WHICH half moved, because they call for different responses. - `retrieval_tuning_events` gains `embedding_model` / `shape_version` (migration 0104), stamped on every write. Nullable and NOT backfilled — "unstamped" is the honest answer for a row written before this existed, and it reports as `stale: null`, never as fine. - `current_settings` reports calibration per dial: tuned rows from their event, untouched dials from the registry default's own stamp. - `retrieval_surfaces` and the Settings panel show the mismatch. The panel renders ONLY when something is stale, so seeing it at all is the signal. - `migrate_floor` / `migrate_retrieval_floor` answers "a path for thresholds to be inherited by the next model so that they don't have to recalibrate a lot": the raw cosine cannot cross models, but the PERCENTILE it represented can. Measure what fraction of a surface's logged calls the old floor admitted, re-score those queries under the current model, take the value admitting the same fraction. Dry run by default; applying writes an ordinary tuning event with the arithmetic in its reason. Nothing auto-retunes. A stale stamp says a number is no longer a measurement; it does not say what the number should be, and #4102 measured the one case where the statistic and the correct action pointed opposite ways. The load-bearing test is an ABSENCE: no chat-model identifier may appear anywhere in the calibration path. Claude produces none of these scores, so a Claude upgrade must trigger nothing — a false alarm here teaches the operator to ignore the real one on the day bge-small becomes bge-base. Backup v17 carries both columns, unfilled on the way out and on the way back: a round trip must not turn "we don't know" into a stated fact.

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.
