Architect storage around SQLite+Honker: remove PG, add multi-tenant identity, scoping

Reorient @alkdev/storage around a single SQLite database host with Honker
for pub/sub, event streams, and task queues. PostgreSQL is removed as a
target (ADR-038), eliminating dual schema maintenance and infrastructure
complexity. Honker provides DB + pubsub + queues in one .db file (ADR-039).

Add system/tenant DB model (ADR-040): identity tables in system.db, all
graph data in tenant-{orgId}.db files. Identity tables move from the hub
into storage (ADR-041). Scoping columns (ownerId, projectId) added to
graphs table (ADR-042). Graph types get scope (system/tenant/user) to
protect infrastructure schemas (ADR-043).

Define Drizzle-Honker session adapter (ADR-044): ~100-line adapter enabling
Drizzle typed queries and Honker pubsub/queue on a single connection with
transactional consistency.

Resolve OQ-03, OQ-04, OQ-19, OQ-21, OQ-22, OQ-23, OQ-24. Add new
open questions OQ-26 through OQ-29 for Honker integration specifics.

New docs: honker-integration.md (adapter, event patterns, migration).
Scrub all PG/jsonb/libsql references from existing spec docs.

# SQLite Host
The SQLite database host for `@alkdev/storage`. Uses Drizzle ORM with
libsql/Turso for the SQLite dialect and `@alkdev/drizzlebox` for TypeBox schema
generation from Drizzle table definitions.
The SQLite database host for `@alkdev/storage`. Uses Drizzle ORM with Honker
for database operations, pub/sub, event streams, and task queues. TypeBox
schemas are auto-generated from Drizzle table definitions via `@alkdev/drizzlebox`.
## Overview
The SQLite host provides:
1. **Drizzle table definitions** for the metagraph pattern (graph types, node
types, edge types, graphs, nodes, edges) plus a standalone `actors` table
2. **Drizzle relations** for the relational query API
3. **TypeBox schemas** auto-generated from Drizzle tables (select/insert
validation)
4. **Injectable database factory**`createSqliteDatabase(client)` accepts a
pre-created client
The SQLite host is the first-class target. PostgreSQL will follow the same table
shapes with appropriate dialect changes.
1. **Metagraph tables** — 6 tables for graph types, node types, edge types,
graphs, nodes, and edges (ADR-002)
2. **Identity tables** — accounts, organizations, organization_members, api_keys,
audit_logs for multi-tenant authentication and authorization (ADR-041)
3. **Drizzle relations** for the relational query API
4. **TypeBox schemas** auto-generated from Drizzle tables (select/insert
validation) via `@alkdev/drizzlebox`
5. **Drizzle-Honker adapter** — thin session adapter for Honker integration
(ADR-044)
6. **Client factories**`createSystemDatabase(client)` and
`createTenantDatabase(client)` for the system/tenant DB model (ADR-040)

**Notable differences from a typical PostgreSQL common columns pattern**:
- `id` is a consumer-generated UUID text PK (no `$defaultFn`)
- `metadata` is an extension namespace following `_subsystem.key` convention
- `createdAt`/`updatedAt` are Unix epoch integers with timestamp mode
- No `$onUpdate` — consumers must set `updatedAt` explicitly
| Column | SQLite | PostgreSQL (typical) |
| ----------- | ------------------------------------- | ------------------------------------------------------------- |

The SQLite columns do NOT have `$defaultFn` for ID generation (the consumer
provides IDs) and do NOT have `$onUpdate` for `updatedAt` (Drizzle's `$onUpdate`
is application-level; consumers must set it explicitly).

become a node type in an ACL graph (based on `@alkdev/operations`'s `Identity`
interface) or remain a standalone table. See OQ-03 in [open-questions.md](./open-questions.md).
Identity tables live in the **system DB** (ADR-040, ADR-041). They provide
multi-tenant authentication and authorization infrastructure. These tables are
derived from the hub's existing identity tables; the schemas are aligned but
simplified for the storage package's scope.

## Client Factory
## Client Factories
### `createSystemDatabase(client)`
Creates a Drizzle database instance with the identity schema (accounts,
organizations, organization_members, api_keys, audit_logs) attached.
```ts
import { createSqliteDatabase } from "@alkdev/storage/sqlite";
import type { SqliteDatabase } from "@alkdev/storage/sqlite";
import { createClient } from "@libsql/client";
import { createSystemDatabase } from "@alkdev/storage/sqlite";
import { open } from "@russellthehipp/honker-node";
const client = createClient({ url: "file:local.db" });
const db: SqliteDatabase = createSqliteDatabase(client);
const honkerClient = open("system.db");
const db = createSystemDatabase(honkerClient);
// Drizzle typed queries
const admins = db.select().from(accounts).where(eq(accounts.accessLevel, "admin"));
// Honker features on the same connection
db.$client.notify("account:created", { accountId: "user-1" });
```
The factory takes a pre-created `@libsql/client` client and returns a typed
Drizzle database instance with the full schema attached. This enables:
### `createTenantDatabase(client)`
- In-memory testing with `createClient({ url: ":memory:" })`
- Turso remote connections
- Custom client configuration (auth tokens, etc.)
Creates a Drizzle database instance with the metagraph schema (graph_types,
node_types, edge_types, graphs, nodes, edges) attached.
```ts
import { createTenantDatabase } from "@alkdev/storage/sqlite";
import { open } from "@russellthehipp/honker-node";
const honkerClient = open("tenant-acme.db");
const db = createTenantDatabase(honkerClient);
// Drizzle typed queries
const activeGraphs = db.select().from(graphs).where(eq(graphs.status, "active"));
// Transactional: insert node + notify in one commit
db.transaction((tx) => {
tx.insert(nodes).values({ graphId, key: "call-1", attributes: {} }).run();
tx.$honkerTx.notify("nodes:created", { graphId, key: "call-1" });

## Metadata Convention
## Removed: `actors` Table
Every table has a `metadata` JSON column defaulting to `{}`. This is an
extension namespace for subsystem use, following a namespacing convention:
`_subsystem.key` (e.g., `_keypal.scopes`, `_retention.expiresAt`).
The `actors` table is removed per ADR-035. `ACTOR_TYPE` is replaced by the
`IdentityType` enum in the AclGraph Module. Identity data lives in the
`accounts` table (system DB) and `PrincipalNode` in ACL graph instances
(tenant DB).
**What metadata is for**: Opaque key-value pairs that subsystems add without
schema changes. It's never queried in WHERE clauses or JOINs.
## Removed: PostgreSQL Porting Notes
**What metadata is NOT for**: A replacement for typed columns. If a field
appears in WHERE clauses, JOIN conditions, or needs a constraint, it should be a
proper column — not buried in metadata. When in doubt, add a column.
**Namespacing convention**: Subsystems should prefix their keys (e.g.,
`_callgraph.payloadRef`, `_acl.inherited`). Unprefixed keys are reserved for the
storage package itself.
PostgreSQL is no longer a target (ADR-038). All porting notes from the previous
version of this document are obsolete. The single database host is SQLite via
Honker.
## Concurrency Model
The SQLite host targets spoke deployments where a single process accesses the
database. For this model, SQLite's default journal mode is sufficient. However,
for spoke deployments that may run concurrent writes (e.g., multiple worker
threads), consumers should:
Honker opens databases in WAL mode with a bounded reader pool and single writer
slot. This handles the expected concurrency for the hub use case:
1. **Enable WAL mode**: `PRAGMA journal_mode=WAL;` — allows concurrent reads
during writes
2. **Set busy timeout**: `PRAGMA busy_timeout=5000;` wait up to 5 seconds for
lock acquisition
3. **Use a single writer**: SQLite supports one writer at a time. If multiple
threads write, route writes through a single queue or connection
- **Reader pool**: Up to `maxReaders` (default 4) concurrent read connections.
`db.$client.query()` uses the pool automatically.
- **Writer slot**: Single exclusive writer, acquired by `transaction()`. If the
slot is occupied, subsequent `transaction()` calls block until released.
- **Write timeout**: Honker sets `busy_timeout=5000` by default. Configurable at
`open()` time.
- **WAL mode**: Enables concurrent reads during writes. Required by Honker's
reader pool architecture.
The `createSqliteDatabase()` factory does not set these pragmas — it's the
consumer's responsibility to configure the SQLite connection appropriately. The
libsql client used to create the connection can be pre-configured before passing
it to the factory.
## PostgreSQL Porting Notes
When implementing `src/pg/`, the table shapes remain the same but with these
changes:
| SQLite | PostgreSQL |
| -------------------------------- | ---------------------------------------- |
| `sqliteTable` | `pgTable` |
| `text` (JSON mode) | `jsonb` with `.$type<T>()` |
| `integer` (timestamp mode) | `timestamp` with timezone |
| `sql\`(strftime('%s', 'now'))\`` | `sql\`now()\`` |
| `integer` (boolean mode) | `boolean` |
| `text` (enum) | `pgEnum` or `text` with check constraint |
See a consumer's `commonCols` pattern (e.g., the hub's
`/workspace/@alkdev/hub/docs/architecture/storage/table-reference.md`) for
PostgreSQL reference patterns.
For multi-process deployments, set WAL mode and ensure the busy timeout is
sufficient for expected lock contention.
