ci(plugin): gate the path that ships straight to users, and fix one more line-oriented cap (#84)

First CI run with shellcheck (run 3029) flagged exactly one thing:

  scribe_session_context.sh:44
  SC1007 Remove space after = if trying to assign a value
  here=$(CDPATH= cd -- "$(dirname -- "${BASH_SOURCE[0]}")" && pwd)

`CDPATH= cd` is the deliberate POSIX idiom for running a single command
with CDPATH empty — it stops `cd` resolving through the operator's CDPATH
and echoing the resolved path into our stdout, which for a hook whose
stdout IS its protocol would be a real bug. shellcheck cannot distinguish
that from a typo'd `CDPATH=cd`, so this is a false positive.

Scoped `# shellcheck disable=SC1007` with the reason above it, matching
how CI-runner's own scripts/install-common.sh handles SC2086. One
line-scoped disable, no file-level or blanket suppression — a lint you
silence broadly stops being a lint.

Everything else in that run passed, including the parts that could only
run once jq was installed: all four hooks exit 0 and stay silent
unconfigured and against a refused connection, with the session-context
hook correctly still emitting its static floor.

+"""add notes.data JSONB — queryable structured fields for typed records
+
+Revision ID: 0070
+Revises: 0069
+Create Date: 2026-07-26
+
+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.

+"""add note_usage_events — did anyone actually open what we surfaced?
+
+Revision ID: 0071
+Revises: 0070
+Create Date: 2026-07-28
+
+`retrieval_logs` records what the ranker returned and with what scores, which is
+the right substrate for tuning a similarity threshold. It cannot answer the
+different question the snippet corpus needs: was a surfaced snippet ever pulled
+in full? A snippet nobody opens still competes for the injection budget on every
+turn, so the surfaced:pulled ratio is what makes dead weight visible.
+
+Two reasons this is its own table rather than columns on `notes` or rows in
+`retrieval_logs`:
+
+  - Counters on `notes` would answer "how many" but not "when, from where, and
+    by which arm" — and the place arm vs semantic arm comparison is precisely
+    what was missing (the write-path place arm surfaced snippets while leaving
+    no trace anywhere).
+  - Folding un-scored surfacing into `retrieval_logs` would corrupt the score
+    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
+and what `retrieval_logs.result_ids` (a JSONB array, one row per *call*) cannot
+be indexed at.
+
+FK-free on note_id and user_id, matching retrieval_logs and app_logs: telemetry
+should outlive what it describes. Deleting a note must not erase the evidence
+that it was surfaced forty times and opened none.
+
+Downgrade drops the table outright. The data is purely observational — nothing
+reads it for correctness, so losing it costs history and no behavior.

+## Scribe MCP
+
+Claude clients connect to the built-in MCP server at `POST /mcp` (streamable HTTP,
+Bearer auth with an `fmcp_` key), served by `src/scribe/mcp/`. It is not a REST
+surface — it exposes the same data as typed tools (`create_note`, `create_task`,
+`start_planning`, `search`, `enter_project`, `list_always_on_rules`, …) with
+server-level usage guidance delivered in the MCP `instructions` block. See
+[API Keys & MCP](api-keys-and-mcp.md).

 # 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.

+italic, lists, code blocks, and task checklists render inline. A slash-command menu
+(`/`) 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.
-
-**Link suggestions** — The editor detects note titles appearing as plain text in the body and suggests converting them to wikilinks.
-
-## Tasks
-
-Tasks carry status (`todo` → `in_progress` → `done`), priority (`none`/`low`/`medium`/`high`), due date, milestone assignment, and a parent task (sub-tasks).
-
-**Task work logs** — Append progress log entries to a task with optional duration. Time tracking is visible in the task editor sidebar.
-
-**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.
+- **Work logs** — Append timestamped progress entries (with optional duration) to a
+  task without rewriting its body; shown chronologically in the task view.
+- **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
+  from and the System(s) it touches.
+- **Recurring tasks** — An interval or calendar recurrence rule spawns the next
+  occurrence when a task is completed (a background job drains due spawns).
+- **Sub-tasks** — Any task can have children via `parent_id`; the viewer shows them
+  inline.
 
 ## 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:
-- **RAG** — Semantically relevant notes (≥ 0.60 cosine similarity) auto-injected as context. Notes 0.45–0.60 shown in sidebar as "Suggested."
-- **Attach notes** — Paperclip icon to include specific notes in context.
-- **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).
+The whole store is reachable by Claude through a built-in **MCP endpoint at `/mcp`**
+(Bearer-auth with an API key). The **Scribe Claude Code plugin** (shipped in this
+repo) wires it up:
 
-## 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.
-
-**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.
+See [API Keys & MCP](api-keys-and-mcp.md).
 
 ## 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.
-
-**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.
+Every read and mutation is scoped by owner + direct shares + group shares.
 
 ## Data Export and Backup
 
-- **Personal export** — Settings → Data: download all notes/tasks as a Markdown ZIP (with YAML frontmatter) or JSON array.
-- **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.
+- **Personal export** — download all your notes/tasks as a Markdown ZIP (YAML
+  frontmatter) or a JSON array.

+name: reusing-code
+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.

+
+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
+says so, and without jq the smoke test is skipped. A skipped check announces
+itself loudly, because a check that quietly no-ops is the failure mode this
+whole file exists to prevent.

+Scribe also stores Snippets — reusable functions/components recorded once for
+recall (note_type "snippet"): a name, language, signature, canonical location
+(repo · path · symbol), a one-line "when to reach for it", and the code. They
+are ordinary embedded notes, so a recorded snippet also surfaces through the
+same search + proactive recall as everything else. Two reflexes: (1) before you
+write a new helper/utility/component, search first (list_snippets(q=...) or
+search) — reuse the prior art with get_snippet(id) instead of re-deriving a
+one-off; (2) the moment you build or notice something reusable, record it with
+create_snippet(name, code, when_to_use, language, signature, repo, path, symbol,
+project_id, system_ids) so a later session is offered it. Make when_to_use sharp
+— it becomes the title, which is what a recall menu shows. Edit an existing one
+with update_snippet rather than recording a second copy; when the same reusable
+thing already exists as several one-offs, unify them into one canonical record
+with merge_snippets (it folds every call site in as a location and trashes the
+duplicates). Keep the record honest: a snippet whose details have gone stale can
+be corrected with update_snippet (an empty string clears a field), and one that
+is wrong or obsolete should be retired with delete_snippet — a bad snippet keeps
+being offered as prior art, which costs more than none at all.
+
+Scribe is multi-user, so some records belong to other people. Anything another
+user owns comes back marked `shared: true` with an `owner`. Treat a shared
+record as THAT PERSON'S SUGGESTION, never as the operator's settled practice:
+weigh it on its merits, attribute it when you reference it, and ask before
+adopting it or acting on it. This matters most for a shared Process — do not run
+one as written; describe what it would do and get the operator's go-ahead.
+Records shared directly with the operator are also deliberately search-only:
+they surface when you look for them (pass a query), not in plain lists, so
+nobody else's material arrives unasked. Editing another user's record needs an
+editor or admin share from them; a read-only share is refused, and the right
+answer is usually to record the operator's own version rather than to push.

 When developing Scribe itself, honor its multi-user sharing ACL: scope every
 read and mutation of user data by owner + shares — never assume a single
 operator. "Works for one user" is not done.

+            been written somewhere else.
+        repo: Narrow to snippets recorded in this repo, matched exactly — the
+            same repo string used when recording, e.g. "Scribe".
+        path: Narrow to snippets recorded at this path. Matches the exact file
+            OR anything beneath it, so "frontend/src" finds
+            "frontend/src/lib/x.ts" as well as itself.
+        symbol: Narrow to snippets recorded under this symbol name, exactly.

+            "attention" is the one to reach for — everything whose recorded

+            "missing", "moved", "changed".
+
+    `repo`/`path`/`symbol` must all match the SAME recorded location, so a
+    snippet that lives in repo A and, separately, at path B in another repo is
+    not returned for repo=A + path=B.
+
+    Returns {"snippets": [{id, title, tags, preview, usage}], "total": int}. The
+    title reads "name — when to reach for it"; open one in full with

+    how often the entry has been put in front of an agent versus actually

+    delete it. Such an entry is not harmless: it takes a slot in every future
+    auto-inject menu and crowds out something useful.
+
+    An entry marked `shared: true` with an `owner` belongs to someone else — one

+    Answers the question RetrievalLog cannot: not "what did the ranker return

+    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).
+    This table is one row per *note per event*, which is the grain the usage
+    readout needs and the grain RetrievalLog's JSONB `result_ids` can't be
+    indexed at. The two are complements: RetrievalLog tunes the threshold, this
+    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
+    no session id — and introducing one would mean threading an opaque,
+    client-supplied token through every read path for a signal that does not
+    need it. Two independent counters answer the question without it: a note
+    surfaced 40 times and never pulled is dead weight regardless of which
+    sessions those events fell in.
+
+    Deliberately FK-free on user_id and note_id (mirrors RetrievalLog/AppLog):

+# before the count and the page slice, so totals stay honest; the Python form
+# runs in the semantic arm, which post-filters candidates it already holds in
+# memory. THE TWO MUST CHANGE TOGETHER — a filter only one arm applies makes a
+# snippet findable by wording and invisible by location, which is exactly the
+# split tests/test_retrieval_scopes.py exists to prevent.
+#
+# Semantics, both dialects:
+#   - parts are ANDed WITHIN a single location entry, never across the list. A
+#     snippet whose first location is in repo A and whose second is at path B
+#     does not answer repo=A + path=B — it was never in that place.
+#   - `path` matches exactly OR as a directory prefix: "frontend/src" finds
+#     "frontend/src/lib/x.ts". Prefix is the one part a GIN containment lookup
+#     can't serve (migration 0070), which is why this is a jsonpath `@?` rather
+#     than `@>` — jsonpath `starts with` is index-served by the same GIN index.
+#
+# The filter reads `notes.data`, so it only sees rows carrying that mirror.
+# Rows written before migration 0070 are populated once at startup by

+"""Note usage telemetry — was a surfaced note ever actually pulled?
+
+Two event streams, deliberately independent:
+
+  - SURFACED: we put this note's title in front of the agent (auto-inject, or
+    either arm of the write-path prior-art trigger).
+  - PULLED: someone then opened it in full (get_snippet / get_note / the REST
+    detail route).
+
+The ratio between them is the signal. A snippet surfaced forty times and never
+pulled is not neutral — it occupies the injection budget on every future turn
+and dilutes the menu — so this is what makes dead weight visible and prunable.
+
+Design notes (mirrors retrieval_telemetry, for the same reasons):
+  - Writes are fire-and-forget. `record_surfaced` / `record_pulled` extract
+    plain ints synchronously and schedule the insert as a background task, so
+    telemetry never adds latency to — or can break — the surface it observes.
+  - Every failure path is swallowed. Losing a usage row costs a data point;
+    raising would cost the operator their retrieval.
+  - Reads (`usage_for_notes`) are NOT fire-and-forget — a readout the caller
+    awaits, aggregated in one round-trip for a whole page of snippets rather
+    than per row.

+"""Real-Postgres integration test for the snippet location reverse lookup (#2083).
+
+Runs only in the CI integration lane (real Postgres, schema built by
+`alembic upgrade head`, which includes migration 0070's `notes.data` + GIN index).
+This exercises what the unit mocks cannot:
+
+  - the jsonpath `@?` containment behind `_location_clause` — including
+    `starts with` for a path prefix, and the fact that parts must match within a
+    SINGLE `locations` entry;
+  - that the SQL dialect and the Python dialect (`location_matches`, used by the
+    semantic arm) return the SAME rows. Those two must never drift, or a snippet
+    is findable by wording and invisible by location;
+  - `backfill_snippet_data`, which is what stops a pre-0070 snippet from being
+    silently reported as "nothing recorded here."
