Domain names become an allocatable resource with one authority. A new
core module (schema `domains`, own migration stream between core and the
integrations) owns claims — a DNS node plus its whole subtree, mutually
disjoint: operator shared-domain roots, member claims carved from them,
and bring-your-own names proven by TXT verification — and placements,
which bind a name inside a claim to a provider slug and resource ref.
Verification moves to the claim and decouples from creation. A member
proves control of a domain once; afterwards every name inside it places
instantly, wildcard-CNAME friendly, with no further DNS work. The claim
workflow activates the claim and stops — it no longer creates a site —
so the sites list offers a one-click create once a domain verifies.
/domains/ask answers from placements and is registered by core rather
than the FedWiki adapter; its HTTP contract is unchanged. A configured
`domains-ask-fallback-url` forwards names the registry does not know to
a legacy answerer, the strangler seam wiki.cafe's migration needs; a
name the registry knows but has archived is refused locally.
FedWiki's create saga reserves the name before the farm call, carrying a
workflow-minted site id so retries are idempotent, and compensates on
failure. Sync places only names it owns, never stealing a member's;
lifecycle transitions and the retention purge maintain servability. An
unconditional boot pass seeds operator roots, releases orphaned
placements, and adopts pre-existing sites — grandfathering member-owned
external domains shortest-name-first, and skipping name policy, so a
live single-letter site cannot lose its certificate.
Members manage domains at /domains: claims with verification status, DNS
records including an optional wildcard row, check-now, cancel, release.
Name policy (reserved, blocked, premium, plus a single-letter guard) is
operator data; refusals collapse to a plain "unavailable" so the console
never becomes an oracle for who holds what.
BREAKING (pre-release): `fedwiki.custom_domain_verifications` and
`sites.is_custom_domain` are dropped, the flag now derived from the
placement's claim kind; resource key `fedwiki_custom_domains` migrates
to the platform-owned `external_domain_claims`; running
verify-custom-domain workflows must be terminated before deploy.
Squash the pre-production migration history into fresh core, fedwiki,
and stripe baselines and reduce the canonical source list to those
three streams.
Update sqlc configs, generated queries, raw SQL, tests, and docs while
keeping provider tables schema-qualified.
BREAKING: existing local database volumes must be wiped because goose
version history restarts from the new baselines.
