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.

|
|
|
|
A rulebook rule is shared by every project that gets the rulebook: an
|
|
always_on rulebook binds ALL your projects; a subscribed rulebook binds the
|
|
projects that opt in. So a rulebook rule must read as a general standard —
|
|
never pin it to one project's files, paths, or quirks. For a rule that
|
|
applies to a single project only, use create_project_rule instead (no
|
|
rulebook+topic ceremony). If it's a standard a CATEGORY of projects shares,
|
|
put it in a themed subscribed rulebook, not the always-on one.
|
|
|
|
Before writing a rule at all, check whether another entity already models
|
|
the thing. A rule is prose an agent must remember and apply; the others
|
|
are structure a tool can resolve, render and check. Visual standards are a
|
|
DESIGN SYSTEM (tokens inherit, resolve per mode, render to a stylesheet —
|
|
none of that survives being prose). A repeatable procedure is a PROCESS.

Reusable code is a SNIPPET. Reach for a rule only when the thing genuinely

is a standing instruction about how to work and nothing else can hold it.
|
|
|
|
ONE RULE = ONE THING YOU COULD VIOLATE. If a clause can be broken on its
|
|
own, and fixing that breakage doesn't require the neighbouring clauses, it
|
|
is a separate rule. Rules that FAIL TOGETHER get linked with relate_rules
|
|
(kind="co_surfaces"), never merged into one row: 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.

push", "when adding a value to a CHECK-gated column", "when a

|
release is being cut". Write it even though the parameter is

optional: it decides the tier below, it is how the rule is found

when it matters, and a rule nobody can place is a rule nobody

applies.

tier: "always_on" (default) or "conditional".
|
|
The test: 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. If you had to name something, it is
