…amed types
`contract infer` never produces a `types { }` block, so the generator was
dropping the nine hand-authored storage-type aliases (`Id`, `Parent`,
`Payload`, ...) and inlining each column full type. That was the main reason
rerunning `contract:generate` did not reproduce the committed contract.
Declare the aliases in the script, keyed by the type spelling infer produces,
rewrite each matching scalar field to reference its alias, and emit a `types`
block holding the aliases that were used. The mapping is by type spelling, not
by column meaning, so a future Supabase release that adds a `varchar(255)`
column will pick up `Parent` automatically and the name needs rechecking.
Drop `canonicalizeNamedTypes` and the `InferredSchema` wrapper it needed: they
merged named-type registries that `inferPostgresPslContract` never produces.
Pin the nine named types and the 43 auth/storage check constraints in
contract-completeness.

… fixture
Rerunning `contract:generate` now reproduces the committed contract except for
three things the generator gets right and the committed file predates. Adopt
all three.
Checks: 43 `@@check` constraints. `contract infer` gained check inference after
this contract was last generated. The fixture declares 45 CHECK constraints,
two of them on tables in schemas the pack does not declare (`_realtime.tenants`
and `realtime.subscription`), so 43 is every check on a declared table.
Type spelling: 78 columns say `Timestamptz` instead of `DateTime`. Identical in
the emitted contract - both produce `pg/timestamptz-temporal@1` over
`timestamptz`.
Enum defaults: six columns (`auth.oauth_clients.client_type`,
`auth.oauth_authorizations.response_type`, `auth.oauth_authorizations.status`,
and `type` on `storage.buckets`, `storage.buckets_analytics`,
`storage.buckets_vectors`) now carry `@default("confidential")` rather than
`@default(dbgenerated("'confidential'::auth.oauth_client_type"))`. This one
changes the emitted contract, not only its text: the column default goes from
`{ kind: "function", expression }` to `{ kind: "literal", value }`. Both
describe the same live default; infer now reads the member out of the cast.
The round-trip verify test confirms the pack still verifies clean against the
restored reference fixture.
The storage hash changes to

…ntract Replace the drift paragraph: rerunning `contract:generate` now reproduces the committed file, and a second run leaves `git status` clean. Record that the checks are declared rather than omitted (43 of the fixture 45; the other two are in schemas the pack does not declare), that the six native-enum defaults are declared as member literals, that all four `text[]` columns waive the derived element-not-null check because real Supabase has no such constraint, and that the nine curated named types are applied by type spelling rather than by what a column means, so a refreshed fixture can hand a new column an alias name that no longer reads correctly. Add the extension upgrade fragment for the new storage hash.

…harden the alias rewrite
contract-completeness asserted a bare count of 43 checks, so it passed if a
constraint were renamed or swapped. Compare the 43 names instead, the way every
sibling test in the file compares a name set. Add the two contract-data facts
nothing in this package pinned: the six native-enum defaults as
`{ kind: "literal", value }`, and the four list columns carrying
`noCheck: ["elementNotNull"]`. All three assertions were checked by mutation -
each goes red when its expected list is perturbed.
In the generator, `applyNamedTypeAliases` rebuilt each aliased field from seven
named properties, which silently dropped any `PslField` property not listed.
Spread the field and remove only the type constructor, so a property added to
`PslField` later survives. The alias lookup also fell back to `field.typeName`,
which is a relation field shape too, so a future Supabase model named `Id` or
`Parent` would have had its relations rewritten into scalars; skip a field whose
type name is one of the document models.
Neither generator change moves the output: regenerating leaves the contract
byte-identical at storage hash
43f09411473534105017fa715b8932facbdf79feab1bfc75da681beb87f22cbc.

…ved check, and scope the check claim to the reference build The fidelity notes and the upgrade fragment both said the `@noCheck(elementNotNull)` waiver was there because the contract would otherwise expect a constraint real Supabase lacks and fail verify. The previous contract disproves that: those columns carried no waiver and the emitted contract held no checks at all, because `defaultControlPolicy: "external"` runs `stripDerivedChecksFromNonManagedTables` over every table before emit. State the real reason instead - `contract infer` writes the waiver for any list column with no live check at the derived wire name, and the committed contract reproduces the generator output - and say in the fragment that the item moves the storage hash and changes nothing else a consumer can observe. Scope the check-constraint claim. The 43 checks come from one pinned reference build and this PR promotes them from a tolerated live extra to a declared shape, so a consumer on a different Supabase build can now fail verify with no way to repair it under external control. Say so in the fragment rather than promising every Supabase database, and record the newly declared surface in the fidelity notes safety-asymmetry section.

…int is declared The check-constraints bullet opened "none of the live ones. All 43 are declared", two clauses that contradict each other when read on their own. The "none" was a leftover from when this bullet listed what the contract omits, and it stopped parsing that way once the regenerated contract declared the checks.

The Supabase extension ships a contract that
scripts/generate-contract.tsis meant to produce, and the fidelity notes claimed that rerunning the generator reproduced it. That claim was false. The generator rewrote roughly 491 lines, because the committed contract was hand-curated before the generator existed and has not been regenerated sincecontract inferlearned to read check constraints. This PR makes the two agree, and proves it: running the generator on the merged result leaves the tree clean.Refs: TML-3249
Changes
The generator writes the curated named types (
packages/3-extensions/supabase/scripts/generate-contract.ts, Extensions). Thetypes {}alias block was hand-authored and the inference path never produces one, so regenerating used to drop it along with every reference to it. The generator now applies the aliases itself. The rule is keyed on the printed type spelling, so a new column of an aliased spelling picks up that alias automatically whatever the column means; that property is stated in the script and in the fidelity notes, because someone adding a column has to check the resulting name still reads correctly. The dead registry-merging helpers the aliases used to route through are gone.The contract is regenerated (
contract.prisma,contract.json,contract.d.ts). Four differences, all of them the committed file being stale rather than the generator being wrong:The storage hash changes.
The fidelity notes are rewritten to match the regenerated contract, including the counts and lists that the regeneration invalidated.
An upgrade fragment records the change for extension consumers: re-sign any database signed against the previous Supabase contract.
The composing example needed no change. Its contract references the Supabase space by id rather than carrying its hash.
Why
The aliases are curated public structure, so dropping them to make the generator win was not acceptable, and leaving the contract hand-maintained was not either, since the notes would keep making a promise the script does not keep. Teaching the generator the aliases gets both: the contract is genuinely generated, and the curated surface survives. Every other difference resolves toward the database, because the generator reads the live schema and the committed file was written before those parts of inference existed.
