jpmschweitzerandClaude Sonnet 5 99ee994023 feat(tenants): add the tenant registry, the one enforcement point Book and Scribe now share (T-8)
A tenant has been an unchecked string since T-4/T-7: the Office's
X-Office-Tenant header or a user JWT's tatlock_user claim, with Book and
Scribe each running their own _require_tenant that checked only presence.
A typo'd claim opened a fresh, empty namespace rather than being refused.

src/domains/tenants/ (controller/models/schemas/service) adds tenants and
tenant_consumers (migration 007, down_revision="006"): tenants.id is the
slug a tatlock tenant carries, kind (household|person|test) and status
(active|suspended) CHECK-constrained; tenant_consumers is the grant pairing
a consumer to a tenant. Migration 007 seeds the two tenants in use today —
jpmschweitzer (household, "Jeroen") and llm_tester (test, "Playground") —
each granted to office-claude, the only Office consumer configured in
Authentik. Every existing owner_tenant column (book_records,
book_tenant_counters, scribe_addresses, scribe_messages,
scribe_mailbox_entries — five, grepped and confirmed) now carries a
foreign key to tenants.id, ON DELETE RESTRICT, at both the migration and
the ORM model.

TenantsService.require_tenant is the one enforcement point: no tenant is
400 tenant_required (unchanged); an unknown tenant is 403 tenant_unknown;
a suspended one is 403 tenant_suspended; an Office caller whose consumer
holds no grant in that tenant is 403 consumer_not_granted. One query — a
LEFT JOIN against the grant — so presence, status and the grant are all
read in a single round trip. Book's and Scribe's own _require_tenant now
delegate to it, translating TenantError to their own exception type so
every call site and each controller's single except clause keep working
unchanged.

Read-only this round: GET /tenants/me answers the caller's own tenant and
its granted consumers (the cheap "am I allowed here" probe); GET /tenants
answers every tenant for a tatlock/scheduler caller, or a list of one for
a tenant-bearing caller — another tenant's existence is never revealed.
No write routes; provisioning a tenant is workspace T-195.

Tests: tests/test_tenants.py and tests/test_tenants_migration.py (new);
a TestTenantRegistryEnforcement class added to both tests/test_book.py and
tests/test_scribe.py proving all four cases (unknown, suspended,
ungranted-consumer, and the control) on a live Book and Scribe route, not
only on /tenants itself. tests/conftest.py gains a tenant_registry schema
fixture and a suspended_tenant fixture (inserted and deleted per test; no
FK references it); book_schema and scribe_schema each independently grant
a second, test-environment-only consumer (office-gemini) in both seeded
tenants, since test_book.py and test_scribe.py have used it as a stand-in
second consumer since before this grant check existed — the migration
itself still seeds only office-claude, matching the dossier.

Mutation-checked: dropping the grant check fails the three
consumer_not_granted tests (200 instead of 403); dropping the status
check fails the three tenant_suspended tests; making Book bypass the
helper fails its unknown-tenant test (200 instead of 403). All three
restored and the full suite re-verified green (508 + 35 = 543 passed).

jpmschweitzerandClaude Sonnet 5 ccdbc44d67 feat(scribe): add the Scribe domain — addresses, send, mailbox, history, find, mark, tag (T-5)
The Office (workspace D-66, D-68, D-73) needs a message bus: an address is
a topic named for an identity, owned by a tenant and a consumer. D-68 puts
it here, in core-api's own database, behind its own auth, following
src/domains/book/.

Migration 006 lands the whole schema by hand (down_revision="005"):
scribe_addresses (owner_tenant + name primary key — no surrogate id, since
no route ever references an address except by name), scribe_messages
(retained; a generated tsvector search column + GIN index on subject/body,
and a GIN index on the topics array for history's lookup), and
scribe_mailbox_entries (one row per recipient address per message, unique
on address+message_id). No data: seeding `jeroen` and `tower-control` is a
deploy step through `register`, not this migration.

Routes, every one behind require_caller("office", "user"), tenant from the
caller (T-4):

- register/list addresses — register is idempotent for the same consumer,
  409 address_taken for another consumer in the tenant; list marks which
  addresses the caller's consumer owns.
- send — `from` is always the caller's own identity, stamped server-side,
  never read from the body; 403 identity_not_owned if that identity is not
  a registered address owned by the caller's consumer; 404 unknown_address
  (naming the missing ones) if any recipient does not exist in the tenant;
  writes one mailbox entry per recipient.
- mailbox / find — the caller's own identity's entries (mailbox: unread
  first; find: full text via websearch_to_tsquery), both requiring the
  identity be owned by the caller's consumer.
- history — the retained messages sent to an address, oldest first;
  reading never consumes or marks, and reads scribe_messages directly
  rather than joining through mailbox entries.
- mark / tag / untag — share one PATCH route; an entry outside the
  caller's tenant, or addressed to an identity the caller isn't reading
  as, answers 404 not_found — indistinguishable from a nonexistent entry.

Every query filters on the caller's tenant (D-73): an address or message
in another tenant answers exactly like one that does not exist, so no id
is ever confirmed across that boundary (test_scribe.py::TestTenantIsolation,
including two tests proving the tenant filter is load-bearing even when
the same address *name* legitimately exists, differently owned, in two
tenants — not just when the caller's own identity is unregistered there).

Messaging only this round: groups, subscriptions, the notification matrix
and delivery are explicitly not built (workspace T-176) — the schema
already carries what `topics`/`tags` need for them.
