Subject: [PATCH] feat(rules)!: retire rulebook subscriptions and per-project
 suppressions (#4052)

A rule's home is its scope now: a rule in a rulebook topic is global, a rule on
a project applies to that project, and retrieval reads that directly (#4074).
A subscription had stopped changing anything a session received; a suppression
muted rules from a subscription. Operator, 2026-09-15: "we have global and
project scoped rules, we don't need the subscriptions now."

What goes, whole (rule 22):
- Migration 0101 drops project_rulebook_subscriptions, project_rule_suppressions
  and project_topic_suppressions, and strips subscribe_rulebooks (and 394's
  leftover exclude_always_on_rulebooks) from stored inception choices.
- Service, MCP and REST: subscribe/unsubscribe and the four suppress/unsuppress
  operations. The Subscribers checklist, the subscribe chips, the skip buttons
  and the Suppressed section in the rules UI.
- Inception asks two questions (design system, seed Systems). create_project and
  decide_project_inception lose subscribe_rulebooks.
- Backup v15 stops exporting the three sections; older archives still restore,
  the keys simply unread. Trash no longer hard-deletes suppression rows.

What changes meaning:
- get_applicable_rules is a project's LISTING: its own rules, plus the global
  rules tagged to an area it works in. Untagged global rules apply everywhere
  and arrive by retrieval, so they are not listed. A co_surfaces partner on a
  different project is not dragged in.
- list_rules(project_id) lists that project's own rules.
- rules_payload drops subscribed_rulebooks and suppressed_*; the handshake's
  brief form is project_rules alone.
- using-scribe's "Where a new rule goes" and inception sections, tool
  docstrings and docs say global vs project. Plugin 2026.09.15.1620.

Milestone 414 step 2.

+"""drop rulebook subscriptions and per-project suppressions
+
+Revision ID: 0101
+Revises: 0100
+Create Date: 2026-09-15
+
+Milestone 414. A rule lives in a rulebook topic, where it is GLOBAL, or on one
+project, and retrieval reads that home directly (step 1). Subscriptions were
+the last thing that pretended a rulebook reached some projects and not others,
+and after milestone 394 they changed nothing a session received — only what a
+project's rule LISTING showed. Operator, 2026-09-15: "we have global and
+project scoped rules, we don't need the subscriptions now."
+
+WHAT GOES
+
+  - ``project_rulebook_subscriptions`` (migration 0058).
+  - ``project_rule_suppressions`` and ``project_topic_suppressions``. They let a
+    project mute rules from a rulebook it subscribed to. With no subscription
+    there is nothing to mute; a project that departs from a global rule writes
+    a project rule with an ``overrides`` relation, which says why.
+  - The ``subscribe_rulebooks`` key inside ``projects.inception.choices``, and
+    the ``exclude_always_on_rulebooks`` key milestone 394 left behind in the
+    same place. Both describe decisions that can no longer be made; a stored
+    record carrying them would be read back as a choice the product offers.
+
+IRREVERSIBLE, AND THE DOWNGRADE SAYS SO
+
+The downgrade recreates the three tables empty. Which projects subscribed to
+which rulebooks, and what they muted, is in what this drops. Restore a backup
+taken before this ran if the prior state matters.

 If `enter_project` returns an `inception` key, the project was never decided
 (it inherits its defaults silently): raise that ask once, with the defaults it
 carries, then `decide_project_inception(project_id, …)`. Existing projects

 ## Where a new rule goes
 
-When codifying a rule, pick its home by **who it should bind** — and keep
-shared homes general:
+A rule has one of two homes, and the home IS its reach:
 
-- **Rulebook** (`create_rule` + `subscribe_project_to_rulebook`) — a reusable,
-  *themed* module of general rules that binds the projects which opt in (e.g. a
-  review checklist → every service). Themed, but project-agnostic.
-- **Project rule** (`create_project_rule`) — anything specific to one project
-  (its files, paths, quirks).
+- **Global** — in a rulebook (`create_rule` into a topic). It applies in every
+  project, and reaches a session wherever the work matches it. A rulebook is a
+  *themed* grouping of general rules (e.g. a review checklist), not a list of
+  projects it binds — there is no subscribing a project to one.
+- **Project** (`create_project_rule`) — anything specific to one project (its
+  files, paths, quirks). It reaches only that project's sessions.
 
-There used to be a third home — an `always_on` rulebook that bound every
-project automatically. It is gone: subscription is the only reach a rulebook
-has. Names one project's specifics → project rule; anything a category of
-projects shares → rulebook. Never put project-specific detail in a rulebook —
-it leaks to every other project that subscribes.
+Names one project's specifics → project rule; a standard that holds wherever
+the kind of work it describes happens → global. Never put project-specific
+detail in a rulebook — it would reach every other project. A project that
+departs from a global rule writes its own and links it with
+`relate_rules(kind="overrides")`, which says why.
 
 **Whichever home it gets, a rule needs `when_to_apply`.** It is the only thing
 that decides whether the rule is ever seen: nothing is preloaded, so a rule

+    than retrieval on purpose — "every global rule" is not a list anyone reads.
+
+    `rules` is the global rules TAGGED to a canonical area this project works
+    in (milestone 307, D7): a deterministic tag match, never a similarity
+    score. Before milestone 414 this was every rule in a SUBSCRIBED rulebook,
+    narrowed by area only where an author had tagged one. With subscriptions
+    gone there is no opt-in left to scope the untagged ones, and an untagged
+    global rule is general by construction — it arrives by retrieval when the
+    work makes it relevant, like every other rule.
+
+    `project_rules` is the project's own, never filtered by area: a rule
+    written ON a project is scoped to it already.

-1. A rule is invisible to a project that doesn't work in its area, and
-   arrives — binding, not suggested — to one that does. Area matching is
-   DETERMINISTIC: a tag comparison, never a similarity score.
-2. A `co_surfaces` partner arrives with its other half, which is the failure
-   that made merging rule 144 into rule 46 look like the only fix.
-3. An explicit suppression outranks an edge.
+1. A global rule tagged to an area arrives in the listing of a project that
+   works in that area, and not before. Area matching is DETERMINISTIC: a tag
+   comparison, never a similarity score.
+2. An UNTAGGED global rule is not listed: it applies everywhere and arrives by
+   retrieval, and listing every one under every project would say nothing.
+3. A `co_surfaces` partner arrives with its other half — the failure that made
+   merging rule 144 into rule 46 look like the only fix — unless the partner
+   lives on a different project, because an edge is not a way in.
 
-TWO CLAIMS WERE DROPPED HERE BY MILESTONE 394, and it is worth saying which
-rather than leaving a shorter list. "A rule with no tier binds exactly as
-before" and "a conditional rule is reachable, not resident" were both about
-the always-on tier. There is no tier and no resident payload, so neither
-states anything that can now be true or false — they were not failing, they
