The write path, and the step where a preference stops being a relabelled
rule. `create_preference` / `update_preference` on the MCP surface, plus
`kind` on update_rule and both HTTP doors.

SEPARATE TOOLS, NOT A `kind=` ARGUMENT. create_rule's docstring IS the
approval gate (#3557): propose, offer three answers, wait. That is right for
a rule — the person it binds should have agreed. A preference inverts it, and
one reached through create_rule would be read through that prose, so the
caller would hesitate over exactly the act this kind exists to make routine.
Two doors, two contracts, one table. Reads stay shared: a preference IS a
rule row, and "what governs this" wants both.

Two required fields, each buying something:

- `when_to_apply`, because the trigger is two-thirds of the embedded
  document. Without one the record is written, stored, and silently never
  delivered — indistinguishable from one nobody wrote.
- `arose_from_id`, the price of the ungated write. A corpus that drifts with
  no record of what taught each change cannot be audited, and the operator's
  veto over drift is worth exactly as much as their ability to read why it
  happened.

The near-duplicate gate is what lets this corpus be written freely and stay
small: the second preference about a thing updates the first. It is
title-scoped and kind-blind, so it also catches a preference restating a rule
that already binds.

The asymmetry is guarded as two PRESENCE facts — the rule door still asks,
the preference door still says write it — never as an absence. An absence
check passes against a docstring that was deleted or rewritten into something
else, which is snippet #3352's warning and would read as coverage here while
proving nothing.

`_plain_detail` moved to tests/helpers on its second copy, per that module's
own reason for existing (#2825).

bvandeusenandClaude Opus 5 6627cfc2f0 feat(rules): a usage badge on the rule list, and the badge becomes canon instead of a second copy (#3319)

Milestone 333 step 5, and rule 27 — the counter had a tuning point from step
4 and no operator-facing one until now.

The task said to reuse the snippet badge's classes rather than mint a parallel
set, citing the eight duplicated CSS families the ledger already carries
(#3207). `.usage-tag` lived in SnippetListView's SCOPED block, so "reuse" was
not available: copying it into the rule pane would have been the ninth family,
and importing it is not a thing a scoped block permits. So it was promoted
rather than copied.

Three pieces, each of which existed once and now exists once:

- `components.css` gains `.usage-tag` / `.usage-dead`, geometry and colour
  only, with the scoped original deleted rather than left behind.
- `UsageBadge.vue` holds the logic the two lists would otherwise duplicate —
  the >=3 dead-weight threshold, the empty-string-renders-nothing rule, the
  tooltip.
- `types/usage.ts` holds `RecordUsage`, one client type over two tables.
  `SnippetUsage` becomes an alias, so no existing consumer changes.

THE ADVICE IS A PROP, and that is the substance rather than the plumbing. The
counts read identically for every kind; the remedy does not. A snippet offered
and never opened should probably be rewritten or deleted — one action. A rule
in the same position has TWO possible causes and the operator has to pick:
its trigger may fire on the wrong work, in which case `when_to_apply` wants
rewording, or it may genuinely not be wanted. Baking "delete it" into the
component would give the wrong nudge half the time on the surface where being
wrong is most expensive, since a deleted rule stops binding behaviour.

The route zero-fills every row through `usage_for_rules`, one aggregate per
page — per-row would be N+1 by construction. That matters more here than for
snippets: every rule on every existing install predates `rule_usage_events`,
so the zero-filled shape IS the common case for a while, and a route that
attached the key only where it found events would leave the badge reading
undefined on almost every row.

`usage_for_rules` had no test at all — step 1 covered the write path and the
zero shape and left the aggregate uncovered, which only became load-bearing
when a list started rendering it. It now has an integration test over real
Postgres, including that a rule with no events comes back zero-filled rather
than absent.

Recorded as snippet #3460, per the design system's own instruction that the
component layer lives as snippets rather than as prose.

Milestone 333 step 2. Step 1 built the table; a counter nobody calls reads zero
and looks exactly like a surface nobody uses, which is #2663's shape.

SURFACED — the standing-rule arm in build_write_path_hint, beside the
record_retrieval it already made. Two tables, and the split is not arbitrary:
retrieval_logs is one row per CALL keyed on the score distribution a threshold
is tuned from; rule_usage_events is one row per RULE per event, the grain "was
this hint ever acted on" needs and the grain a JSONB result_ids array cannot be
indexed at.

The comment there said rule ids had nowhere to go — that note_usage_events
remaps ids on restore, so a rule id would return attached to whatever note took
that number. Still true of the NOTE table, and precisely why step 1 built its
own. Rewritten to say the gap is closed rather than leaving a stale rationale
that would have someone re-derive the same dead end.

Records `fresh`, i.e. AFTER exclude_rule_ids. A rule the session already holds
was considered and not shown; counting it would inflate the denominator with
claims the agent never saw, and the ratio would then fall for a reason that has
nothing to do with whether hints land.

PULLED — two doors, both after their access check so a refused read is not a
pull. mcp_get_rule is the one that matters: the arm's own message ends "Read it
with get_rule(N)", so that call is the exact action a landed hint produces.
rest_rule carries the other prefix, and the prefix is load-bearing — "is this
rule dead weight?" is served by any pull, "did that injected hint land?" by
agent pulls only.

NOT a pull: rule_history. It loads the rule for its title and its own output
says "The current wording is on the rule itself — get_rule(N)", so counting it
would credit a read of the history as a read of the rule and double-count
anyone who then follows that pointer. list_always_on_rules and enter_project
are likewise bulk resident loads, not somebody choosing to open one record.

tests/test_rule_usage_wiring.py is cross-cutting on purpose: the surfaced end
is in plugin_context, the pull end in two other modules, and "both ends meet"
is a property no module-shaped file asserts. It covers the exclusion boundary,
that a failing recorder cannot break the write, that a refused read records
nothing, and two completeness guards — every door records, and the bulk loaders
still do not.

`list_rule_versions` / `get_rule_version` in the rulebooks service, a pair of
REST routes beside the note-version ones, and an MCP `rule_history` tool.

The ACL-scoped reads live in services/rulebooks.py rather than in
services/rule_versions.py because rulebooks already imports rule_versions for
the write path and the reverse would be a cycle. It is also the honest split:
rule_versions owns what a version IS, rulebooks owns who may read one.

Scoping is through the RULE, never the version's user_id, and both directions
of that mistake are now pinned by tests. That column is the ACTOR — scoping
by it would hand someone the snapshots they personally wrote on a rule that
has since moved out of their reach, and would hide from the rule's owner
every edit anyone else made. `get_rule_version` takes the rule id as well as
the version id so the ownership check and the fetch agree about which rule is
in play; the test for that uses a second rule the caller genuinely owns,
because a nonexistent id would pass on the ownership check alone and prove
nothing.

An unreadable rule returns None, not an empty list. The two mean different
things — "not your rule" versus "never reworded" — and the MCP tool keeps
them apart: None raises, empty says so in band.

THE DIFF QUESTION, ANSWERED — and the task's premise was half wrong. It says
"notes have DiffView.vue and a diff endpoint already". The component exists
and is reusable as-is: it takes `DiffLine[]` and nothing note-shaped, so step
4 can render a rule diff with it unchanged. The ENDPOINT does not exist —
diffs are computed client-side by `computeDiff` in useAssist.ts. So no diff
route is needed here, and none was written.

For the MCP door the answer is different again: an agent has no client to
compute a diff, but it also does not need one. Each entry holds the text the
edit REPLACED, so "what did this say before the most recent change?" is the
first entry, and the text that change produced is the rule as it stands. The
docstring says so, and a test pins that sentence — read the other way round,
every diff comes out backwards.

No restore, per the task. Putting an old wording back goes through
update_rule, which snapshots what it replaces, so the undo stays visible like
any other edit.

bvandeusenandClaude Opus 5 410d616c22 feat(rules): the staleness sweep — which standing rules assert a fact nobody has confirmed (#3097, milestone 312 step 3)

The query the last two steps were storage for. `rules_due_for_verification`
returns every rule carrying a `verify_with`, ordered by `verified_at` ASC
NULLS FIRST, each row carrying the check IN FULL — the opposite call from
rule_brief, because the reader is about to go and run it.

NULLS FIRST is the ordering this turns on. Postgres sorts NULLs last on an
ASC ordering, which would put the rules nobody has ever confirmed BEHIND
every rule someone once looked at. Exactly backwards: a claim with no
evidence at all outranks an old one.

Rules with no check never appear, and that is the property that keeps the
list worth reading. Most rules are decisions — no truth value, nothing to go
and check. If they appeared here the sweep would be the rulebook.

`mark_rule_verified(rule_id, still_true)` closes the loop, asymmetrically:
passing writes a stamp, FAILING WRITES NOTHING. There is no "verified false"
state because a rule whose check failed is not in a special condition, it is
wrong — and recording the failure as a flag would let it sit there being
false with the sweep satisfied that someone had looked. So it stays at the
top until someone corrects or retires it, and the response says so.

An unrecognised `tier` filter raises rather than falling back. _valid_tier's
silent always_on default is right for a WRITE — a typo should leave a rule
binding — and wrong for a FILTER, where the same fallback quietly answers a
different question and returns a short list that reads as good news.

Deliberately NOT filterable by project: a project reaches rules through
project scope, subscriptions, always-on rulebooks and exclusions, and a
filter missing one of those paths would UNDER-report — the exact failure
this surface exists to prevent. Said so in the docstring rather than
shipping a half-correct filter.

Ownership-scoped like every other rule read (owned rulebook, or owned
project), in ONE statement with an OR across the XOR rather than two queries
merged in Python, so the ordering is the database's and cannot disagree with
itself. Note that rules have no sharing ACL in this schema — no rule_shares,
no rulebook_shares — so there is no wider set for access.py to consult here.

Also fixes a test title that had been lying for ten tools: "all sixteen
tools" asserted 26. The number now lives only in the assertion.

verify_with / expires_when now reach a rule through both doors and come back
on every read. The open question this step existed to settle was how to
UNSET a nullable field, and the answer is one convention per door:

- MCP: "" still means "leave unchanged" — an agent filling three fields must
  not wipe the other five — so clearing is explicit, clear_fields=["..."].
  Naming the field is the one form that cannot happen by accident.
- REST: a cleared form input arrives as "", and the service normalises "" to
  NULL for every nullable rule column, so an emptied input does what it looks
  like it does.

Two idioms, one outcome, and the normalisation is what makes the step-3 sweep
correct: `verify_with IS NOT NULL` would otherwise be true for every rule ever
touched through the UI, and the sweep would list the whole rulebook and mean
nothing. to_dict renders "" and NULL identically, so this is only visible
against a real column — hence the integration module rather than a mock.

Editing verify_with drops verified_at. A stamp certifies A CHECK, not a rule;
reword the check and the old stamp vouches for something that no longer
exists. Safe direction, same asymmetry as _valid_tier: a rule wrongly listed
as due costs one look, a rule wrongly vouched for costs the thing the sweep
exists to catch. Editing anything else leaves the stamp alone, or a rulebook
tidy-up would reset every constraint and the ordering would carry nothing.

Reads: rule_brief attaches `last_verified` ONLY to a rule that carries a
check — its presence is the signal, and it says both "this asserts a fact
that can go false" and "here is how long ago anyone confirmed it". "never"
rather than null, per #2483. The check text itself stays in get_rule; a
listing needs to know which rules can rot, not how to test them. Search hits
carry the full trio, since a hit is exactly the moment someone is about to
act on a rule.

Also folds in the #3078 finding, which had been sitting as a note: create_rule
now teaches that when_to_apply is the retrieval surface and must carry the
SYMPTOM — the words you would type while stuck — not just the situation.

fake_rule gains the three fields as None for the reason the helper already
documents one line up: unnamed, verify_with is a truthy MagicMock and every
stand-in rule would claim a check it does not have.

MCP and REST both gain when_to_apply / tier / system_ids / arose_from_id on
create and update, plus relate_rules / unrelate_rules for the typed edges, and
get_rule now returns a rule's areas and relations alongside it.

rule_detail() is a SERVICE function, not one per door. It started as a copy in
each — identical, and the prior-art hook flagged it immediately, which is the
same lesson rules_payload (#2858) already recorded: a second copy drifts. Both
doors call the one seam, so create, update and get cannot disagree about what a
rule looks like coming back.

The authoring guidance lands in create_rule's docstring rather than in a rule,
per rule 119 as the operator described it: this is behaviour every instance
should inherit, not one operator's preference. It states the test —

  ONE RULE = ONE THING YOU COULD VIOLATE. Rules that FAIL TOGETHER get linked
  with relate_rules(kind="co_surfaces"), never merged into one row.

— and names why merging loses: a merged rule cannot be cited, surfaced or
suppressed a clause at a time, and it grows without limit because adding to it
is always cheaper than adding a rule. create_project_rule says the same about
"overrides", which is what FabledCurator's 85/86 should have been instead of
near-copies that drift from their parent.

The tier arg carries the test itself: can you name the trigger WITHOUT naming a
system, an artifact type or a moment? If the honest answer is "whenever you are
working", it is always_on.

Tests: the applicable-rules cases fabricated raw tuples matching the old column
lists, so they move to the entity shape via fake_rule; new cases pin rule_brief
(a DATE not a stamp, the depth left to get_rule, no null keys) and that an
unknown tier falls back to BINDING. fake_rule gains when_to_apply / tier /
arose_from_id for the note-2109 reason the helper exists: unnamed, they would
be truthy MagicMocks. The tool tests stub the new rule_detail seam — they are
about argument forwarding and have no database.

The module header's "Sixteen tools" had been wrong for two milestones; the
registration count test is what actually catches that, so the header now says
so instead of carrying a number.

Reading the 28 route modules against each other and against the MCP tools:
- routes/notes.py carried a PUT and a PATCH handler that were the same
  function minus the supersedes contract on one of them — one handler now
  serves both verbs, so both carry it.
- The two _attach_supersession copies (REST + MCP) become
  supersession_svc.attach_relations(uid, note_id, data, hint=) — the seam
  the two surfaces must agree through; only the agent surface adds the
  one-sentence reading hint.
- Three local _uid() wrappers over g.user.id → scribe.auth.get_current_user_id
  like every other module; design_systems' private _not_found → routes.utils.
  not_found; the four "********" literals → settings_svc.SECRET_MASK with the
  read/write contract written once.
- routes/plugin.py: the project_id/repo resolution block and the
  comma-separated id parse were copied into three endpoints — _project_scope()
  and _int_list() now.
