feat(design-systems): link /design to its editable half

The two pages are halves of one surface — what the browser renders and the

 # Fabled Scribe
 
-A self-hosted second brain and project management application with integrated LLM capabilities. Write, organise, and act on your notes and tasks with the help of a local AI assistant — all running on your own hardware.
+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, and kanban project workspaces. AI chat with streaming responses, RAG over your notes, and tool use (web search, calendar, weather). A daily briefing that digests your tasks, RSS feeds, and weather on a schedule. Knowledge graph, per-user/group sharing, PWA with push notifications, and an MCP server for external AI clients.

+
+Snippets (note_type='snippet') carry structured fields — name, language,
+signature, and a list of canonical locations (repo · path · symbol). Those were
+stored as a markdown body-convention, which reads well and feeds the embedding
+but cannot be QUERIED: answering "which snippets live in this file?" meant
+scanning every snippet and regexing its body.
+
+This adds a general `data` JSONB column plus a GIN index, so those fields become
+indexable. The body stays exactly as it was — it is still the human-readable
+form and still what gets embedded. `data` is a queryable mirror of the same
+facts, not a replacement, and the code itself is deliberately NOT copied into it
+(the body already holds it; duplicating a blob to index fields around it would
+be waste).
+
+Relationship to 0069: that migration DROPPED `notes.metadata`, a JSONB column
+which only ever held person/place/list entity fields, when those surfaces were
+removed. This is not a revival of it — different name, different purpose, and
+nothing reads the old shape. The column is named `data` rather than `metadata`
+because `metadata` collides with SQLAlchemy's declarative `Base.metadata`, which
+is why the old model had to map an awkward `entity_metadata` attribute onto it.
+
+Nullable with no backfill, deliberately: rows written before this migration keep
+working because the service falls back to parsing the body when `data` is
+absent. That means no migration deadline and no risk of a backfill mangling a
+hand-edited body.
+
+Downgrade drops the index and the column. Any structured fields it held remain
+recoverable from the body convention, which is the same source they mirror.

+
+  - Counters on `notes` would answer "how many" but not "when, from where, and

+    distribution that table exists to capture. Location hits have no score.
+
+Grain is one row per note per event, which is what the per-snippet readout needs

+Revises: 0071
+Create Date: 2026-07-30
+
+Makes the design system a first-class record instead of prose in a rulebook: a
+named set of tokens with an optional parent, so a family system holds the house
+style and an app system holds only what it changes.
+
+`design_systems.parent_id` is the whole model. It replaces both an `always_on`
+flag (a family system is one with no parent) and a subscription join table (a
+project points at ONE system, and the chain supplies the rest), which is less
+schema than the rulebook shape it mirrors.
+
+Two deliberate choices worth stating here rather than leaving to be re-derived:
+
+  - **`design_tokens.value_by_mode` is JSONB keyed by mode**, not `value_light` +
+    `value_dark` columns. In a child system an unset mode means "inherit"; in a
+    root it would mean "not mode-dependent", and as columns both are NULL and
+    indistinguishable. As a map, resolution is a dict merge at every level with
+    no special case for roots — and a third mode (high-contrast, print) is data
+    rather than a schema change. The cost is that a typo'd mode key is not
+    rejected by the database. Nothing filters tokens by value in SQL, so the
+    queryability the columns would have bought is for a query no caller makes.
+    (Named `value_by_mode` rather than `values`, which is reserved in SQL.)
+  - **`group_name` is free text, not a CHECK enum.** Groupings are each design
+    system's own vocabulary; a whitelist would bake one install's kit into the
+    schema. No CHECK is introduced anywhere in this migration.
+
+`parent_id` and `projects.design_system_id` are both ON DELETE SET NULL. Deleting
+a family system must orphan its children into roots that still hold their own
+overrides, not cascade away every app system that inherited from it; deleting a
+system a project points at must unstyle that project, not delete it.
+
+Downgrade drops both tables and the column. Any design system defined this way
+is lost — this is the migration that introduces the concept, so there is no
+earlier representation to fall back to.

 # Features
 
+Scribe is a self-hosted work system-of-record for software projects, built to be
+driven by Claude Code. There is **no in-app LLM** — Claude is the sole assistant,
+reaching Scribe through a built-in MCP endpoint and a bundled Claude Code plugin. The
+web UI is a clean surface for humans to read and edit the same data.
+
 ## Notes
 
-Write in Markdown with a live-preview editor (Tiptap/ProseMirror). Headings, bold, italic, lists, code blocks, and task checklists render inline. A slash-command menu (`/`) inserts common blocks.

+(`/`) inserts common blocks.
 
-**Wikilinks** — Link notes with `[[Title]]` or `[[Title|Display Text]]` syntax. Clicking a wikilink navigates to (or auto-creates) the referenced note. The editor suggests existing note titles as candidate links while typing `[[`. Backlinks appear in the note viewer sidebar.
+- **Wikilinks** — Link notes with `[[Title]]` or `[[Title|Display Text]]`. Clicking
+  navigates to (or auto-creates) the referenced note; the editor suggests existing
+  titles while you type `[[`. Backlinks appear in the note viewer sidebar.
+- **Tags** — First-class `ARRAY[text]` column with autocomplete. Hierarchical tags
+  (`area/backend`) supported — filtering by `area` matches all `area/*` children.
+- **Version history** — Every body edit snapshots a version (up to 20 per note).
+  Browse, diff, and restore from the editor's History panel.
+- **Draft recovery** — In-progress edits persist across page loads and are restored
+  when you reopen a note.
+- **Convert freely** — Turn a note into a task (sets `status=todo`) or back again.
 
-**Tags** — First-class `ARRAY[text]` column. Tag autocomplete in the editor sidebar suggests existing tags. Hierarchical tags (`project/webapp`) supported — filtering by `project` matches all `project/*` children. Tags are browsable via the knowledge graph.
+## Tasks and Issues
 
-**Version history** — Every body edit snapshots a version (up to 20 per note). Browse and restore from the editor's History panel. Diff view shows changes against the current body.
+Tasks carry status (`todo` → `in_progress` → `done`/`cancelled`), priority
+(`none`/`low`/`medium`/`high`), due date, milestone assignment, and a parent task
+(sub-tasks). Notes and tasks share one model — a task is a note with a status.
 
-**AI writing assist** — Select a passage or work on the full document. Give an instruction ("make this more concise", "add examples"). The assistant streams a proposal; a diff view shows changes to accept or reject. Drafts persist across page loads.
+- **Work logs** — Append timestamped progress entries (with optional duration) to a
-
+  task without rewriting its body; shown chronologically in the task view.
-**Link suggestions** — The editor detects note titles appearing as plain text in the body and suggests converting them to wikilinks.
+- **Issues** — A task whose `kind` is corrective: a problem you fixed or are fixing,
-
+  with symptom → root cause → fix in the body. An issue can link the task it arose
-## Tasks
+  from and the System(s) it touches.
-
+- **Recurring tasks** — An interval or calendar recurrence rule spawns the next
-Tasks carry status (`todo` → `in_progress` → `done`), priority (`none`/`low`/`medium`/`high`), due date, milestone assignment, and a parent task (sub-tasks).

+  inline.
-
-**Sub-tasks** — Any task can have child tasks via `parent_id`. The task viewer shows sub-tasks inline.
-
-**Convert freely** — Convert a note to a task (sets `status=todo`) or a task back to a note from the viewer toolbar.
 
 ## Projects and Milestones
 
-**Projects** — Group related notes and tasks. Each project has a title, description, goal, status (`active`/`completed`/`archived`), and a colour.
+- **Projects** — Group related notes and tasks. Title, description, goal, status
+  (`active`/`paused`/`completed`/`archived`), and a colour.
+- **Milestones** — Ordered stages within a project. A milestone is also the home of a
+  **plan** — its body holds the design (Goal/Approach/Verification) and its child
+  tasks are the steps. Completion percentage is shown on the project page.
+- **Kanban view** — `/projects/:id` groups tasks by milestone in a column layout with
+  status-advance buttons on the cards.
 
-**Milestones** — Ordered stages within a project. Tasks are assigned to milestones. Milestone completion percentage shown on the project page.
+## Systems
 
-**Kanban view** — `/projects/:id` groups tasks by milestone in a kanban-style column layout with status-advance buttons directly on cards (→ advance, ✓ complete).
+A **System** is a per-project, reusable, self-describing subsystem or area (e.g.
+"auth", "billing"). Associate any note, task, or issue with a System so research,
+build-work, and fixes for the same area line up and recurring problem-spots surface.
 
-**Project Workspace** — `/workspace/:projectId` opens a three-panel environment (tasks / chat / notes) locked to a project. The AI assistant creates and updates content directly in the workspace; new notes auto-load in the editor and the task list refreshes automatically after tool calls.
+## Rules and Rulebooks
+
+Scribe stores the operator's engineering and workflow **rules** so Claude follows them
+across sessions.
+
+- **Rulebooks → topics → rules** — Rules are grouped by topic inside a rulebook.
+- **Always-on rules** — A rulebook can be flagged always-on; its rules load at the
+  start of every session through the plugin's push channel.
+- **Per-project scope** — A project subscribes to rulebooks, and can add
+  project-scoped rules or suppress individual inherited rules/topics.
+
+## Stored Processes
+
+Reusable saved prompts (a note with `note_type=process`) — e.g. a drift-audit or a
+DRY pass. The bundled plugin syncs each Process into a local Claude Code skill stub
+(`/scribe:sync`) that auto-surfaces by relevance and fetches the live procedure on
+demand.
+
+## Search and Knowledge Injection
+
+- **Semantic search** — pgvector-backed similarity search over notes and tasks
+  (in-process `fastembed` embeddings; no external model).
+- **Proactive knowledge-injection** — the plugin's `UserPromptSubmit` hook surfaces a
+  short, high-confidence menu of maybe-relevant note *titles* into Claude's context
+  each turn; Claude pulls a full body only when it judges it relevant. Gated so it
+  stays quiet on most turns and never repeats within a session.
 
 ## Knowledge Graph
 
-`/graph` renders all notes, tasks, and tags as a D3 force-directed graph. Tag nodes cluster notes that share tags; invisible project hub nodes attract project members. Physics controls: repulsion, link distance, link strength, hub pull, gravity. Click any node to open a slide-in peek panel. Click a tag node to filter the notes list.

-## AI Chat
+## Claude via MCP and the plugin
 
-Full conversation history with SSE streaming. Features:
+The whole store is reachable by Claude through a built-in **MCP endpoint at `/mcp`**
-- **RAG** — Semantically relevant notes (≥ 0.60 cosine similarity) auto-injected as context. Notes 0.45–0.60 shown in sidebar as "Suggested."
+(Bearer-auth with an API key). The **Scribe Claude Code plugin** (shipped in this
-- **Attach notes** — Paperclip icon to include specific notes in context.
+repo) wires it up:
-- **RAG scope chip** — Pill above the input bar shows the current note scope. Click to switch: "Orphan notes only" (default — project notes stay out of general chat), any active project, or "All notes." Scope is persisted per conversation. The AI can also call `search_projects` and `set_rag_scope` mid-conversation to switch scope automatically; the chip pulses when this happens.
-- **Tool calls** — The assistant can create/update notes, tasks, projects, milestones, search the web, check weather, read RSS, query calendar events, and more. Tool calls display inline with confirm/deny for creates.
-- **Thinking mode** — Toggle extended reasoning for complex questions.
-- **Abort** — Stop button cancels in-flight generation.
-- **Message queue** — Messages sent while generation is in progress are queued and drained sequentially.
-- **Save to note** — Save any assistant reply directly as a note.
-- **Bulk delete** — Select and delete multiple conversations.
-- **Retention** — Conversations auto-pruned after configurable days (default 90).
 
-## Daily Journal
+- a `SessionStart` hook that injects the operator's always-on rules + active-project
+  context so Scribe surfaces without being asked (fail-open if Scribe is unreachable);
+- universal process-skills — writing-plans, systematic-debugging, verification,
+  brainstorming — that route their output into Scribe;
+- your saved Processes auto-surfaced as skills.
 
-`/journal` is a conversational daily surface — each day is a chat-style conversation seeded with an LLM-generated daily prep as the first assistant message. The prep pulls together today's tasks, calendar events, weather, recent moments, and active projects in flowing prose, then invites the user to continue the conversation throughout the day.
+See [API Keys & MCP](api-keys-and-mcp.md).
-
-**Schedule** — Daily prep generates at a configurable time (default 5:00am). The "day rollover hour" controls when the journal switches to a new day (default 4am — late-night entries 1–3am still count as the previous day). Scheduler catches up missed runs on startup.
-
-**Right rail** — The journal view shows current weather conditions and upcoming events for the next two weeks alongside the conversation. Both surfaces draw from the same data the prep references.
-
-**Configuration** — Settings → Profile:
-- *Locations* section: home and work place-name inputs (geocoded on blur via Nominatim) and a temperature unit toggle (C/F)
-- *Journal* section: prep auto-generate toggle, prep generation time, day rollover hour
-- *About You* / *Interests* / *Work Schedule* / *Response Preferences* feed personalization into the prep's system prompt
-
-**Weather** — Location-based forecast via Open-Meteo. Up to two named locations (home, work). Cached rows auto-refresh in the background when the journal page loads.
-
-**What the assistant has learned** — The assistant maintains a per-user observation log + consolidated summary, generated from journal and chat conversations. The summary is included in the journal's system prompt so the daily prep can reference what it knows about you over time.
-
-## Web Research
-
-The assistant can search the web (SearXNG) and fetch pages, synthesising findings into a structured multi-note research output: an index note with an executive summary and links to focused section notes. Each section covers a distinct aspect of the topic with cited sources. Falls back to a single note when outline generation fails. A lightweight `search_web` tool answers quick questions inline without saving. Requires `SEARXNG_URL` to be configured.
-
-## Calendar
-
-`/calendar` shows a full FullCalendar view (month, week, day). Click an empty slot to create an event; click an existing event to edit or delete it via a slide-over panel.
-
-**Internal events store** — Events are stored in the app database (`events` table), making them available without any external calendar. Fields: title, description, start/end datetime, all-day toggle, location, colour.
-
-**AI tools** — `create_event`, `list_events`, `search_events`, `update_event`, `delete_event` all operate on the internal store. Tool-call result cards in chat are clickable and open the same EventSlideOver for editing.
-
-**HomeView widget** — The dashboard shows today's and the next 7 days' events as clickable cards above the hero project.
-
-**CalDAV sync (optional)** — Connect an external CalDAV server (Nextcloud, Radicale, etc.) in Settings → Integrations. Events sync bidirectionally via a `caldav_uid` field.
 
 ## Sharing and Collaboration
 
-**Share** — Share any project or note/task with users or groups at `viewer`/`editor`/`admin` permission levels. Share button in the viewer/project toolbar opens a dialog.
+- **Share** — Share any project, note, or task with users or groups at
+  `viewer`/`editor`/`admin` levels from the viewer/project toolbar.
+- **Groups** — Admins create platform-wide groups and assign `member`/`owner` roles;
+  share a resource with a group in one action.
+- **Shared with me** — `/shared` lists incoming shares with permission badges.
+- **Notifications** — An in-app bell (unread count, polled) fires when a project or
+  note is shared with you or you're added to a group.
 
-**Groups** — Admins create platform-wide groups and assign users `member`/`owner` roles. Share a resource with a group in one action.
+Every read and mutation is scoped by owner + direct shares + group shares.
-
-**Shared with me** — `/shared` lists all incoming shared projects and notes with permission badges.
-
-**Notifications** — Bell icon in nav shows unread count (60s polling). Notifications generated for: project shared, note shared, added to group. Click navigates to the resource.
-
-**Push notifications** — Web Push (VAPID) notifies when AI generation completes, even in another tab. Works over HTTPS only. Configurable per-user.
-
-## Quick Capture
-
-Quick capture from the Android app routes to the intent classifier. It creates notes, tasks, or projects based on content — using the user's configured model, not the hardcoded default.
 
 ## Data Export and Backup
 
-- **Personal export** — Settings → Data: download all notes/tasks as a Markdown ZIP (with YAML frontmatter) or JSON array.
+- **Personal export** — download all your notes/tasks as a Markdown ZIP (YAML
-- **Admin backup** — Full application backup (version 2): includes projects, milestones, task logs, AI drafts, note versions, push subscriptions. ID remapping on restore for cross-instance migration.

+ * a gallery of hand-written look-alikes drifts from the app within a month and
+ * then lies — which is the same failure this whole surface exists to catch. So
+ * every specimen below is either a REAL component imported from the app, or a
+ * real token read from the browser, or it is explicitly marked as missing.
+ *
+ * Buttons are the case where that bites. Rule 65 specifies four variants, but
+ * `.btn-primary` is defined four separate times in four `<style scoped>` blocks
+ * and 30 of 54 SFCs carry their own button CSS (#2273). There is no shared
+ * button to import, so rendering one here would just make this a fifth copy.

+# Scribe — your system of record
+
+This environment has the **Scribe** plugin: the operator's self-hosted system
+of record (notes, tasks, projects, milestones, rules) reachable through the
+`scribe` MCP tools. Treat Scribe — **not local files** — as the source of truth
+for the operator's work, and as your own working memory across sessions.
+
+**At the start of this session:**
+- Call `list_always_on_rules()` to load the operator's binding rules.
+- If the working repo maps to a Scribe project (check `list_repo_bindings`),
+  call `enter_project(<id>)` to load that project's rules, open tasks, and
+  recent notes in one shot.
+
+**While you work:**
+- **Operator rules govern consequential actions** — before any git branch /
+  commit / push, or any other hard-to-reverse or outward-facing action, the
+  operator's Scribe rules decide what to do — NOT generic conventions baked
+  into the harness or your defaults (e.g. "branch before committing," "open a
+  feature branch per task," "push to a fork"). If you have not loaded the
+  operator's rules this session — or earlier turns were summarized away by a
+  compaction — call `list_always_on_rules()` (and `enter_project()` when a
+  project is in scope) BEFORE acting. When a loaded rule and a default habit
+  disagree, the rule wins; if no rule speaks to it, ask rather than assume.
+- **Recall before acting** — before you answer anything about the operator's
+  work or start a task, `search` Scribe first; assume a related note, task, or
+  decision already exists. Concretely, reach for recall whenever a request
+  touches the operator's projects, people, places, prior decisions, or existing
+  work: check for an existing task before opening a new one, and for a prior
+  note/decision before re-deriving one. When a project is in scope (you entered
+  one), pass its id to `search` so results stay scoped to it. Treating Scribe as
+  the first place you look — not just somewhere you write — is what makes it a
+  trustworthy record.
+- **Record as you go** — track work as Scribe tasks and log progress with
+  `add_task_log`. Always log when you **complete a task** and when you **hit or
+  discover a problem** — so changes of direction are captured, not just
+  successes. Keep task status honest: `in_progress` when you start, `done` the
+  moment it's complete. When you **fix** something — even in passing — record it
+  as its own issue (`create_task(kind="issue")`), not as a work-log line on an
+  unrelated open task.
+- **Reuse before rebuilding** — before writing a new helper/utility/component,
+  search recorded **snippets** (reusable code recorded once for recall) and
+  reuse the prior art instead of re-solving it; when you build something
+  reusable, record it with `create_snippet` (name, code, when-to-reach-for-it,
+  location) so a later session is offered it, not left to write it again.
+- Do **not** keep the operator's rules, plans, or project notes in local
+  memory / CLAUDE.md in parallel with Scribe — Scribe holds the single copy.
+- **Compact at clean seams** — because you record as you go, a context
+  compaction is safe: the durable record lives in Scribe, not the transcript.
+  After finishing a block of work in a long session, make sure in-flight state
+  is logged to Scribe, then tell the operator it's a good, safe moment to
+  `/compact` (name what you logged). You can't run it yourself — surface the
+  recommendation and let them decide. Suggest it at seams, not every turn.
+
+If the Scribe tools are unavailable, say so rather than silently falling back
+to local notes.

+description: Use when you're about to write a helper, utility, hook, or reusable component — search recorded snippets FIRST so prior art is reused instead of re-solved. And the moment you build or notice something reusable, record it as a snippet so a later session finds it. Triggers on "write a util/helper", "I need a function that…", "let me add a component", or just having built something worth reusing.
+---
+
+# Reusing code — recall before you rebuild
+
+Reusable code is worth writing once. Scribe stores **snippets** — a named,
+reusable function or component recorded with its language, signature, canonical
+location (repo · path · symbol), a one-line *"when to reach for it,"* and the
+code itself — so prior art can surface *before* it's re-written as a one-off.
+Snippets are ordinary embedded notes, so a recorded one also surfaces on its own
+through recall/auto-inject; this skill is the active reflex around that.
+
+## Before you write a new helper — search first
+
+- About to write a utility, hook, formatter, adapter, or a reusable component?
+  **Search snippets before writing it.** `list_snippets(q="…")` (or a plain
+  `search`) — a matching one may already exist, in this project or another.
+  `list_snippets` searches every project by default; that's deliberate, since a
+  helper you need here was quite possibly written somewhere else. Narrow with
+  `project_id` only when you specifically want this project's own.
+- **About to edit an existing file? Ask by place, not just by meaning.**
+  `list_snippets(repo="…", path="…")` answers "what canonical helpers are already
+  recorded here?" — `path` matches the exact file or anything beneath it, so
+  `path="frontend/src"` covers the whole tree. Cheaper and sharper than a
+  wording search when you already know where the code is going, and it catches
+  the helper you'd otherwise duplicate a few lines down. `symbol="…"` narrows
+  further, and all three must match the same recorded location. Combine with `q`
+  to ask both at once.
+- If a snippet fits, pull it in full with `get_snippet(id)` and reuse it — its
+  `location` points at the reference implementation. Adapt, don't re-derive.
+- If auto-inject already surfaced a snippet title that looks relevant, that's
+  your cue to `get_snippet` it rather than start from scratch.
+- **Prior art offered beside a write is not noise — read it.** When Scribe notes
+  that a snippet is already recorded for the file you just wrote or edited, open
+  it before you go any further. Either it's the helper you were about to
+  duplicate — reuse it and drop yours — or it isn't, and the record needs the new
+  location adding. Both are cheaper now than after the duplicate settles in.
+
+## The moment you build something reusable — record it
+
+- Just wrote (or noticed) a helper, hook, pattern, or component worth repeating?
+  Record it with `create_snippet` while it's fresh:
+  - **name** — what it's called, e.g. `useDebouncedRef`.
+  - **code** — the implementation.
+  - **when_to_use** — one sharp line on when to reach for it. This becomes part
+    of the title, so it's what a later recall menu shows — make it earn the pull.
+  - **language**, **signature**, and **location** (`repo` / `path` / `symbol`)
+    so the recorded copy points back at the canonical source.
+  - **project_id** / **system_ids** to associate it with the work it belongs to.
+- Record the *reference* implementation, not every call site — one good entry
+  per reusable thing. If it already exists, `update_snippet` it instead of
+  recording a second copy (the create gate will flag a near-duplicate anyway).
+
+## A shared snippet is a suggestion, not a standard
+
+Scribe is multi-user, so a search can return snippets other people own. Those
+come back marked `shared: true` with an `owner`.
+
+- Read one as **that person's suggestion**, not as the way things are done here.
+  Judge the code on its merits before reaching for it.
+- Say whose it is when you propose it — "there's a snippet from *alex* that does
+  this" — so the operator can weigh the source, not just the code.
+- Don't treat it as the house pattern, and don't build on it at scale, without
+  the operator agreeing to adopt it.
+- Snippets shared directly with the operator only appear when you search for
+  them, never in a plain `list_snippets` — so anything ambient is genuinely
+  theirs.
+
+## Keep the record honest
+
+A recorded snippet is offered as prior art on every matching turn, so a wrong
+one costs more than a missing one.
+
+- Details gone stale — a renamed symbol, a moved file, a signature that's
+  changed? Fix it with `update_snippet`. Passing an **empty string** clears a
+  field, so a wrong signature or location can be removed, not just written over.
+- Recorded something that turned out not to be reusable, or that no longer
+  exists? Retire it with `delete_snippet` — it goes to the trash and can be
+  restored. Don't leave it competing for attention.
+
+## Found the same thing in several places — unify it
+
+When you notice the same reusable thing recorded (or written) as several
+one-offs, don't leave the duplicates competing in recall — **merge them**.
+`merge_snippets(canonical_id, [other_ids])` keeps one canonical record, folds in
+the others' call sites as locations, and retires the duplicates to the trash.
+The result is a single entry that shows every place the thing is used — which is
+exactly the signal that it was worth consolidating. This is the cure the create
+gate only hints at when it blocks a near-duplicate.
+
+## Why this pays off
+
+A one-off written a second time is the cost this avoids. Recording a snippet
+once — with a location and a crisp "when to use" — means the next session is
+offered the prior art instead of re-solving it. Search before writing; record
+what's worth reusing.

+## Recall first
+
+Before digging in, `search` Scribe for the symptom — a prior issue
+(`list_tasks(kind="issue")` or `search`) may already hold the cause and the fix.
+Don't re-debug what's already solved.
+
+## The loop
+
+1. **Reproduce** — get a reliable, minimal repro. If you can't reproduce it, you
+   can't confirm you fixed it.
+2. **Observe** — read the actual error / log / state. Don't theorize past the
+   data you have.
+3. **Isolate** — narrow to the smallest failing case; change one variable at a
+   time so each result actually means something.
+4. **Hypothesize → test** — state the single most likely cause, then test *that
+   one thing*. Confirm or rule it out before moving on; don't stack guesses.
+5. **Root cause** — keep going until you can explain *why* it failed, not just
+   what made it stop. "It works now" without "because X" is unfinished.
+6. **Fix + verify** — fix the cause, then re-run the repro to confirm it's gone.
+
+## Capture the issue (so it's findable)
+
+When resolved, record it in Scribe as its own issue (`create_task(kind="issue")`):
+**symptom → root cause → fix → how it was verified** in the body, optionally
+linked to the task it arose from (`arose_from_id`) and the subsystem it touches
+(`system_ids`). Even a problem fixed in passing is worth two lines — that's how

+it as a work-log line on an unrelated open task. If the work was already tracked

+**already holds** — so make reading it a reflex, not something you wait to be
+asked for.
+
+## Do this first (every session)
+
+**Pull the standing rules yourself — do not wait for them to be handed to you.**
+At the start of a session, before substantive work, call
+`list_always_on_rules()` to load the operator's always-on rules. If the working
+repo maps to a Scribe project (you're in a known repo, or `list_repo_bindings`
+shows a binding), call `enter_project(id)` instead/as-well — it returns the
+project plus its applicable rules, open tasks, and recent notes in one shot.
+
+Do this actively. A SessionStart hook *may* also inject a rule index, but treat
+that as a bonus, not a precondition: it can be absent (e.g. when the instance is
+unreachable, or the token didn't reach the hook), so the reliable path is this
+explicit pull. Rules loaded this way are **binding** for the session.
+
+## Scribe holds these functions — don't keep a second copy
+
+This plugin makes Scribe the home for the operator's **rules, recall, and
+planning** — the jobs Claude's native auto-memory would otherwise do. When the
+plugin is present, route those jobs to Scribe and **do not also write them to
+native memory**: codify rules with `create_rule` / `create_project_rule`,
+capture durable knowledge as Scribe notes, and keep plans in Scribe milestones
+(via `start_planning`) — not in `MEMORY.md` or `CLAUDE.md`. One copy, in Scribe; let any existing local
+memory shrink as Scribe takes over. Don't maintain both stores in parallel.
+
+Two constraints on *how* that's achieved:
+
+- **Steer behavior; never flip a native switch.** The plugin must work with
+  native auto-memory at its default (ON). Never tell the operator to set
+  `autoMemoryEnabled:false` or otherwise disable a built-in function to make
+  Scribe "win" — a setting the operator may not know was changed (and wouldn't
+  know to restore) is exactly the hidden breakage to avoid. You replace memory's
+  functions by *doing the work in Scribe*, not by turning memory off.
+- **A Scribe-shaped hole is acceptable.** If the plugin is later removed, the
+  operator recovers context over time — that's fine. You do **not** need to keep
+  native memory as a self-sufficient fallback. The only thing to avoid is
+  breakage caused by a settings change the operator didn't make knowingly.
 
 ## The reflex
 
 1. **Recall before acting.** Before answering a question about the operator's
    work, or starting a task, `search` Scribe (and `list_tasks` / `list_notes`)
-   for prior art — an existing ticket, decision, or dev-log — instead of
+   for related prior work — an existing task, decision, or note — instead of

-   rules.
 
 3. **Update over duplicate.** When recording, prefer updating an existing
    note/rule/task over creating a new one. Search first; revise what's there.
 
 4. **Plans live in Scribe.** For non-trivial work call `start_planning(project_id,
-   title)` FIRST — the plan body + step checklist live in the `kind=plan` task,
+   title)` FIRST — it creates a milestone whose `body` holds the design; each
-   progress goes in work-logs (`add_task_log`). Do not write plans/specs to local
+   step is its own task under that milestone (`create_task(milestone_id=...)`),
-   `.md` files.
+   progress goes in work-logs (`add_task_log`). Read it back with `get_milestone`.
+   Do not write plans/specs to local `.md` files.
 
 5. **Keep state honest.** Set a task `in_progress` when you start it, `done` the
    moment it's complete; log progress as you go.
 
+6. **Fixes are issues, not work-logs.** When you fix a problem — even one solved
+   in passing — record it as its own issue (`create_task(kind="issue")`) with
+   symptom → root cause → fix, optionally linked to the task it arose from
+   (`arose_from_id`) and the subsystem it touches (`system_ids`). Don't bury a
+   fix as a work-log line on whatever task happened to be open.
+
+## Stay inside the active project's scope
+
+Once a project is in scope — you called `enter_project`, or the working repo is
+bound — confine the session to it:
+
+- **Pass that `project_id` to every read** (`search`, `list_tasks`,
+  `list_notes`). An unscoped read bleeds every other project's work into your
+  context.
+- **Only reference or offer work on the in-scope project.** Don't surface,
+  suggest, or start work on other projects unless the operator explicitly widens
+  scope.
+- If something clearly belongs to a *different* project, say so and **ask before
+  switching** — never silently operate cross-project.
+
+## Where a new rule goes
+
+When codifying a rule, pick its home by **who it should bind** — and keep
+shared homes general:
+
+- **Always-on rulebook** (`create_rule` in an `always_on` rulebook) — universal
+  norms that bind *every* project. Cross-project standards only.
+- **Subscribed rulebook** (`create_rule` + `subscribe_project_to_rulebook`) — a
+  reusable, *themed* module of general rules that binds only projects that opt
+  in (e.g. a design system → visual apps). Themed, but still project-agnostic.
+- **Project rule** (`create_project_rule`) — anything specific to one project
+  (its files, paths, quirks).
+
+Both rulebook tiers are shared, so their rules stay general; they differ in
+**reach** (all vs opt-in), not generality. Names one project's specifics →
+project rule; a standard a category shares → subscribed rulebook; a universal
+norm → always-on rulebook. Never put project-specific detail in a shared
+rulebook — it leaks to every other project that gets it.

Triggers when the user asks you to plan, design an approach, scope an effort, or tackle work big enough to need ordered steps. The plan lives in a Scribe milestone (via start_planning), not a local file.
+---
+
+# Writing plans
+
+A plan is **how** you'll execute a chunk of work — the design plus an ordered
+set of steps — written *before* you start, so the approach is reviewable and the
+work stays trackable.
+
+## Start the plan in Scribe, not a file
+
+For non-trivial work, call **`start_planning(project_id, title)` FIRST** —
+before any design or implementation. It creates a **milestone** (the plan
+container) seeded with a design template and returns the milestone id plus the
+project's applicable rules. The plan lives in that milestone:
+
+- The **design/intent** goes in the milestone `body` — edit it with
+  `update_milestone(milestone_id, body=...)`.
+- Each **step** is its own task under the milestone — create it with
+  `create_task(milestone_id=<that milestone>)` and track it with status +
+  `add_task_log`. Steps are first-class tasks, **not** checkboxes in the body.
+- Read the whole plan back with `get_milestone` (body + its step-tasks).
+
+**Do not** write plans or specs to local `.md` files — the milestone is the
+record, not a file on disk. (The old `kind=plan` task is retired; `start_planning`
+no longer creates one.)
+
+Before designing from scratch, **recall**: `search` Scribe for a related prior
+plan or decision. Often the thinking (or half of it) already exists.
+
+## What a good plan contains
+
+- **Goal** — what "done" looks like, and why, in a sentence or two (milestone body).
+- **Approach** — the key design decisions and the trade-offs you chose, briefly
+  (milestone body).
+- **Steps** — an ordered set of step-tasks under the milestone, each small enough
+  to verify on its own; note which files/areas each touches.
+- **Verification** — how you'll know it actually works (a test, CI, an
+  observable behavior), not just "it's written."
+
+## While executing
+
+- Keep the plan **honest**: drive each step-task's status (todo →
+  in_progress → done) as it lands; record decisions, findings, and pivots with
+  `add_task_log` on the relevant step rather than silently rewriting the body.
+- If reality diverges from the plan, **update the milestone body** — a design
+  that no longer matches what you're doing is worse than none. Add or re-scope
+  step-tasks as the work changes.
+- Mark the milestone `done` when its steps are complete.
+
+## Match depth to the work
+
+A two-step change deserves a two-line plan; a multi-day effort deserves a
+fleshed-out milestone body and several step-tasks. Don't over-plan the trivial,
+and don't under-plan something that will sprawl. The point is a shared,
+reviewable intent — not ceremony.

+WHY THIS EXISTS. `plugin/` is not built into the Docker image. Installs fetch it
+from this git repo via `.claude-plugin/marketplace.json`, so a push IS the
+release for plugin content: no build, no gate, immediately fetchable. Two
+separate defects have reached a live install through that path:
+
+  - #2198 — all four hook scripts were inert (wrong env-var case, line-oriented
+    `jq -rR`, line-oriented `cut -c`). No CI ran, because `plugin/**` wasn't in
+    the workflow's `paths:` filter at all.
+  - #2209 — the fix for #2198 shipped to `main` and still couldn't reach an
+    install, because `plugin.json`'s version wasn't bumped and the installer
+    compares versions to decide whether to refresh its cache.
+
+The rule for the second one was already written down and was still missed. A
+written rule that depends on being remembered during a long session is not a
+control; this is.
+
+shellcheck and jq are NOT in `ci-python` (verified against CI-runner's Dockerfile
+and scripts/install-common.sh, not from memory — rule #37). CI installs both
+per-job, which is what CI-runner's own docs/process.md prescribes for a dep with
+a single consumer: "If only one project needs the dep, prefer that project
+installing it per-job in their workflow — at least until a second consumer
+arrives." Promotion into the image is filed as an issue there rather than
+assumed here.
+
+Both are optional at runtime: without shellcheck the lint step is SKIPPED and

   todo/in_progress/done/cancelled, optional priority). A task is a note with a

   time with work-logs (add_task_log) rather than rewriting the body.

+            "frontend/src/lib/x.ts" as well as itself.

+"""Design systems — a stylesheet held as records, inherited family -> app.
+
+A DesignSystem is a named set of design tokens with an OPTIONAL parent, and that
+single self-FK is the whole model. A system with no parent is a family system; a
+system WITH one holds only what it changes. "What does this app alter?" is
+therefore `list its tokens` — nothing to compute, nothing to diff — which is why
+inheritance won over a flat family-plus-loose-overrides shape.
+
+Resolution walks the chain and lets the deepest system win by token name. That
+is the CSS cascade rather than an analogy to it, which is why the storage model
+and the stylesheet model come out the same shape.
+
+`parent_id` also replaces two things the rulebook model needs to express the same
+idea: an `always_on` flag (a family system is simply one with no parent) and a
+subscription join table (a project points at ONE system, and the chain supplies
+the rest). Less schema for more structure.

+    `value_light` / `value_dark` columns here:
+
+      - **Absence means one thing.** In a child system an unset mode means
+        "inherit"; in a root it would have to mean "not mode-dependent". With
+        columns those are both NULL and the resolver cannot tell them apart. With
+        a map, resolution is `{**parent_map, **child_map}` at every level —
+        one rule, no special case for roots.
+      - **Per-mode overrides are already real.** A palette rule in this operator's
+        own kit deepens one accent on light backgrounds for contrast while
+        leaving the dark value alone. Mode is a second override axis, not a
+        second column.
+      - **Nothing filters tokens by value in SQL.** Drift comparison resolves the
+        set first and compares in the client; the importer diffs in Python. The
+        queryability columns would buy is for a query no caller makes.
+
+    The cost is real — a third mode is data rather than schema, so the DB will
+    not reject a typo'd mode key. That is the trade taken.

+    nobody opens is not neutral — it competes for the injection budget on every
+    future turn and dilutes the menu — so the surfaced:pulled ratio is what
+    makes dead weight visible and prunable.
+
+    WHY A SEPARATE TABLE FROM RetrievalLog. RetrievalLog is one row per *call*,
+    keyed on the score distribution it exists to capture; folding un-scored
+    events into it would corrupt exactly the distribution threshold tuning reads
+    (see the KNOWN GAP note this closes in plugin_context.build_write_path_hint).

+    tunes the corpus.
+
+    WHY NOT IN-SESSION CORRELATION. The original framing was "correlate
+    result_ids against a later get_note in the same session". There is no
+    session identity server-side — the MCP endpoint is stateless and hooks send

+
+    Deliberately FK-free on user_id and note_id (mirrors RetrievalLog/AppLog):
