Milestone #254 step 2 (#2287). `resolve_tokens` flattens a system's inheritance
chain into its effective token set — walk to the root, deepest wins by token
name. Pure and duck-typed, so a test states a whole hierarchy in literals and
the service hands the same function ORM rows.

**Provenance is stored as the contest, not the winner.** A ResolvedToken carries
every system that offered a value, per mode, deepest first — `[0]` won and
`[1:]` are what it shadowed. "Which system supplied this?" and "what did it
override?" are then two reads of one list and cannot disagree, where a winner
plus a separate provenance field would be two things to keep in step.

**Merging is per (name, MODE), and that is the storage decision paying off.** A
system that deepens one accent for light backgrounds while leaving dark alone
owns `base` and still inherits `dark`. A token-level "overridden here" flag
would have to lie about one of them, and the two-column shape could not have
represented it at all.

Metadata cascades separately by the same deepest-wins rule, with one exception:
`order_index` treats 0 as UNSTATED rather than "first", because 0 is the column
default. Reading it as a real value would let a colour-only override drag its
token to the top of its group — a visible reshuffle in return for a change that
touched nothing structural.

One fix to step 1 while wiring this up: `_parent_map` is now scoped to the
SYSTEM'S OWNER rather than the caller. A caller reading through a shared project
owns no link in the chain, so the caller-scoped version would have handed them
an empty forest and truncated the cascade to a single system — a page rendering
with plausible wrong values and no error anywhere. The ACL already grants read
along the whole chain; this is the loading side keeping that promise, and it now
has a test naming the shared-project case.

`BASE_MODE` moves from the model to the cascade module, where it belongs: it is
a resolution rule, not a storage fact, and design_cascade.py deliberately
imports nothing so both access.py and the service can depend on it.

Milestone #254 step 1 (#2286). A design system becomes a record Scribe holds
rather than prose in a rulebook: a named set of tokens with an OPTIONAL parent,
so a family system carries the house style and an app system carries only what
it changes. Answering "what does this app alter?" is then `list its tokens` —
nothing to compute.

`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; the chain supplies the rest) — less schema than the rulebook shape
it mirrors.

Two decisions the task left open, settled here:

- **Token values are JSONB keyed by mode**, not `value_light`/`value_dark`
  columns. The deciding argument was not flexibility, it was ambiguity: in a
  child system an unset mode means "inherit", in a root it means "not
  mode-dependent", and as columns both are NULL and the resolver cannot tell
  them apart. As a map, resolution is `{**parent, **child}` at every level with
  no special case for roots. Against it: queryability — but nothing filters
  tokens by value in SQL, so that buys a query no caller makes.
- **`group_name` is free text, no 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, so rule #36 does not fire.

The cascade lives in `services/design_cascade.py` as pure functions over a
`{id: parent_id}` map, importing nothing — which is what lets both the service
and `access.py` use it without a cycle, and lets a test state a whole hierarchy
in one literal. Cycles are refused on WRITE by walking up from the proposed
parent (the cheap direction), and survived on READ by a visited-set, because a
loop from a direct DB edit must truncate rather than hang.

ACL (rule #78) is deliberately asymmetric: owning a system grants write,
reaching one through a project you can see grants READ ONLY. An editor on a
shared project must not be able to rewrite the family system every other project
in that family resolves through.

Also renames `services/design_system.py` -> `design_rulebook_import.py`. It is
the #251 prose extractor, whose role is already scheduled to become a one-shot
importer (#2288), and leaving it one character away from the new
`design_systems.py` was a trap for every later session.

Rule #115 throughout: nothing seeds a system or implies a default. An install
with zero design systems is ordinary, not degraded.

bvandeusenandClaude Opus 5 2b85443dd1 feat(snippets): usage signal — was a surfaced record ever actually pulled?

retrieval_logs answers "what did the ranker return, at what scores" — the
right substrate for tuning a threshold. It cannot answer the question the
snippet corpus actually needs: did anyone open this? A snippet nobody
opens is not neutral. It takes a slot in every future auto-inject menu and
crowds out something useful.

Adds note_usage_events (migration 0071): one row per note per event,
either 'surfaced' (we put its title in front of an agent) or 'pulled'
(someone opened it in full), tagged with which surface produced it.

Closes the gap #2082 recorded against this work. The write-path PLACE arm
carries no score, so it has no home in retrieval_logs — folding it in
would corrupt the score distribution that table exists to capture. The
result was that the arm firing on the STRONGEST claim ("there is already a
canonical helper in this exact file") was the one arm nobody could
measure. Both arms now emit usage events under distinct sources, so their
pull-through rates are finally comparable.

Deliberate departures from the task as written:

- 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 the
  hooks send no session id — and adding one would mean threading an
  opaque client-supplied token through every read path. Two independent
  counters answer the question without it: surfaced 40×, pulled 0 is dead
  weight regardless of how those events distribute across sessions.

- Pulls record at the ENTRY POINTS (MCP tools, REST detail route), not in
  snippets_svc.get_snippet, which update and merge also reach. Counting
  those would inflate precisely the number meant to say "someone chose to
  look at this."

- get_note records for every note kind, not just snippets. The auto-inject
  menu surfaces tasks and processes too; scoping this to snippets would
  pin those at zero pulls forever and make them read as dead weight next
  to snippets that merely had a counter.

Surfaced in the Snippets list as an "N/M used" badge, warning-toned once a
record has been offered 3+ times and never opened, with the tooltip saying
what to do about it (usually: its "when to reach for it" doesn't say
when). No badge at all below one surfacing — "0/0" reads as a verdict when
it's an absence of evidence. Also returned from MCP list_snippets so the
agent can see dead weight without opening the UI.

Telemetry keeps the retrieval_telemetry contract throughout: writes are
fire-and-forget, reads degrade to zeroes, and no path can raise into the
surface it observes.

Narrow Scribe to a Claude-Code work system-of-record (milestone #194,
decision note #1759). Wholesale removal per rule #22 — backend + schema half.

Calendar/events + CalDAV: delete models/event, services/{events,caldav,
caldav_sync}, routes/events, mcp/tools/events; strip event branches from
backup (bump v3->v4), dashboard (upcoming_events), trash, recent, and the
mcp server read-only allowlist + instructions.

Typed entities (person/place/list): delete mcp/tools/entities; drop the
notes.metadata (entity_meta) column from model/service/routes and the
knowledge browse service. note_type STAYS — it also marks 'process' notes.

Scheduler: event_scheduler -> recurrence_scheduler, keeping only the
recurring-task spawn job (drops event reminders + CalDAV sync).

Schema: migration 0069 drops the events table + notes.metadata column +
orphan caldav settings rows (faithful downgrade recreates them).

KEEP: recurrence.py (task recurrence), notifications task reminders, graph
view, and every work surface. Frontend + plugin/docs true-up follow next.

Add retrieval_logs (migration 0068) + services/retrieval_telemetry with a
fire-and-forget record_retrieval(), wired into the MCP search tool
(source=mcp_search) and the REST search route (source=rest_search). Captures
query, effective params, and the per-result score distribution so KB-injection
thresholds can be tuned from data rather than guessed.

Scribe: project 2, milestone 93, task 1032.

First slice of the Issues + Systems feature (spec #825, plan #819 T2).

Schema (migration 0065):
- task_kind CHECK expands work|plan -> work|plan|issue (same-change, rule 36)
- notes.arose_from_id: optional self-FK for issue->originating-task provenance
  (distinct from parent_id sub-task hierarchy)
- systems: per-project, self-describing (name + description) subsystem/area
- record_systems: M2M join linking any note/task/issue to systems (mutable)

Models: System + RecordSystem; note.py gains arose_from_id (+ index, to_dict).
Service services/systems.py: CRUD, archive, soft-delete, set/list associations,
records-for-system, open-issue count — all gated via services/access.py project
permissions (rule 78, no bare-owner filters). Unit tests lock the ACL gating;
the migration is exercised by CI's integration lane (alembic upgrade head).

is_task stays a derived property (status is not None) — unchanged. T1 (typing-
axis rationalization) intentionally NOT bundled; this only adds the enum value.

The SessionStart hook asked for a project_id via plugin userConfig, which pins
one install to a single project — wrong for an operator working across many
repos/projects. Resolve the active project server-side from the working repo's
git remote instead (a stable identifier, not a dir-name guess).

- repo_bindings table (migration 0064) + RepoBinding model: (user, repo_key) ->
  project, FKs CASCADE.
- services/repo_bindings: normalize_repo_key collapses ssh/https/scp/creds/port/
  .git to host/owner/repo; resolve/set/list/delete.
- GET /api/plugin/context takes ?repo=<remote>; unbound repo -> a "bind this
  repo" hint with a ready bind_repo() call. project_id kept as manual override.
- MCP tools: bind_repo / list_repo_bindings / unbind_repo.
- Hook sends ?repo=$(git remote get-url origin) URL-encoded; all project_id
  handling removed. plugin.json drops the project_id userConfig (0.1.2 -> 0.1.3).
- Tests: normalize equivalence classes + unbound-hint rendering.

Renames src/fabledassistant -> src/scribe and all imports, plus the
default DB name and DB user/password (fabled -> scribe) in config +
compose. 952 refs / 154 files. Reverses the old 'internal name stays
fabledassistant' convention.

Code-only: live databases are still physically named 'fabledassistant'.
Deployed environments must set POSTGRES_DB / POSTGRES_USER (or rename the
DB) since the defaults now resolve to 'scribe'. Repo (FabledScribe), git
host (fabledsword), MCP (fabled-git) and the image name (fabledscribe)
are intentionally unchanged.

ruff check src/ clean locally; CI (typecheck + pytest) is the gate.
