Implements the first ADR 0050 slice: Core's ORM-neutral executor and its
PostgreSQL evidence. Nothing is wired to modules yet; manifest v8, SDK
adapters, schema metadata, packaging, and Signage are later slices. The
legacy ModuleDatabase facade is unchanged.
Contracts (@ekklesia/contracts, no imports at all):
- ABI version 1; query { text, values, rowMode } returning
{ command, rowCount, rows, fields: [{ name, typeOid }] };
- executor, transaction, and savepoint types with exactly the ABI's
members; parameter and result value types;
- ModuleDatabaseError { code, sqlState? }: eight stable codes, and a
SQLSTATE only when PostgreSQL supplied one; static messages, no cause,
frozen; isModuleDatabaseError recognises it by shape.
Core (createModuleDatabaseExecutor over the API's existing pool):
- one statement per query, enforced by forcing the extended query
protocol so PostgreSQL itself refuses a second statement (42601);
no SQL parsing;
- parameters: null, boolean, number, bigint, string, Uint8Array, and
rectangular arrays of them; everything else refused before sending;
- a Core-owned decoding table that never consults pg's global parser
registry: int8, numeric, temporal, and JSON as exact text; bytea as a
plain Uint8Array; built-in arrays element by element;
- every operation pins TimeZone, DateStyle, IntervalStyle, bytea_output,
and extra_float_digits, then resets with DISCARD ALL before returning
the connection, or destroys it when it cannot be reset cleanly;
- callback-scoped transactions with explicit isolation and access mode;
a COMMIT that PostgreSQL answers with ROLLBACK is reported as failed;
- savepoints named by Core; only the innermost scope is active; scopes
are revoked when their callback settles;
- a callback that settles with work outstanding is rolled back, never
committed or released;
- transaction-control statements sent through query are refused by
command tag and transaction status, and fail the transaction;
- the module ID is carried for Core's attribution only.
Tests:
- 83 integration tests on a database with hostile defaults: queries,
the one-statement rule, parameters, decoding, errors, transactions,
savepoints, forgotten awaits, pool safety after every failure class,
and session state;
- unit tests for encoding, decoding, options, sanitization, and scope
bookkeeping;
- type-level and source checks that no ORM or driver object crosses
the boundary.
ADR 0050 is Accepted.

# Architecture decision records
|
|
|
|
ADRs capture durable choices that affect more than one package or phase.
|
|
|
|
- Filenames use a four-digit sequence followed by a short kebab-case title.
|
|
- Status is `Proposed`, `Accepted`, `Superseded`, or `Rejected`.
|
|
- Accepted ADRs are immutable except for status and cross-reference corrections.
|
|
- A changed decision receives a new ADR that links to and supersedes the old one.
