packages/drivers/driver-sql/README.md documents `DriverSQL.configure()` three times — the class is not exported and the static does not exist

[os-steve]

Found while rewriting packages/mcp/README.md (#9579), by sweeping published READMEs for the shape that card is about: a method call on a receiver check:published-readme-exports cannot see.

The finding

packages/drivers/driver-sql/README.md tells the reader to build a stack driver like this, at three separate call sites:

Line	Claim
448	driver: DriverSQL.configure(getDatabaseConfig())
482	driver: DriverSQL.configure({ client: 'pg', connection: { … }, debug: true })
516	driver: DriverSQL.configure({ … })

Measured against the built packages/drivers/driver-sql/dist/index.d.ts:

• DriverSQL is not exported. Zero occurrences of the identifier anywhere in the type entry. The real export is SqlDriver — which the same README imports correctly at line 43, so the page contradicts itself.
• No configure static exists on SqlDriver or on anything else the package exports. Grepping configure in the type entry returns two hits, both prose inside doc comments.

This is the PluginAudit.configure() shape from #9517 / #9532, still live on a page npm renders (README.md is in files, private unset).

Why the gate did not catch it

Both halves of check:published-readme-exports key on a name the fence imported. The fences at 448/482/516 import nothing; DriverSQL appears out of nowhere as a free identifier, so the import half has no claim to make and the call-site half never adds it to localNames. #9544 recorded a different row in this same file (line 137, the IDriver subpath) and PR #9581 fixed that one — this one sat one section further down, outside what the gate reports.

Census behind that: across the 60 published markdown documents, 38 carry at least one method call on a receiver the gate cannot see, 235 call sites in total. This is the one instance in that population that measurably names nothing real.

Why this is not a mechanical substitution

Swapping in the real export does not produce working code: SqlDriver has no configure either, so the correct form is a decision about how a host actually supplies a driver to defineStack — the same class of question the mcp README needed a ruling for. Filing rather than folding it into #9579, whose ruling is scoped to packages/mcp.

Claimed by the domain:devx PM seat — dispatching to an os-dev subagent now.

• Session ID: session_01XqDQYVU5smx29ts9pAErja
• Branch: claude/issue-9867-driversql-configure
• Container & model: S, mode:subagent, model: opus (SKILL default tier; neither mandatory clause applies — no .claude/skills/pm-dispatch/** edit, and nothing here changes a contract's accept/reject behaviour or widens public surface. ⚠️ note Decide: does mandatory-fable clause ② cover packages/lint authoring rules that newly reject clean metadata? (PR #9890 held) #9894 is an open decision on clause ②'s boundary; it does not reach this card.)

State: pm:queue → pm:dispatched, assigned os-steve.

H1 — the working form, with compile evidence

plugins: [new DriverPlugin(new SqlDriver({ … }))].

History checked before assuming, per the dispatch. DriverSQL.configure() was never real: commit 86d1d5ee1b (2026-05-07) calls it "the imaginary .configure(...) static factory" and repaired it in this same file — but only in the Basic Usage section. That is the source of the internal contradiction the card names: correct SqlDriver import at line 43, fabricated DriverSQL at 448/482/516. No commit ever added a DriverSQL class.

But the form that repair produced is also wrong. It wrote defineStack({ driver: new SqlDriver(...) }), and driver is not a declared key. Corroborated three ways: skills/objectstack-platform/rules/bootstrap-patterns.md ("There is no driver: key on defineStack()… Drivers are plugins"); the already-merged #9544 changeset, which recorded the same fact for packages/mcp; and real call sites (examples/app-todo/test/*.ts use kernel.use(new DriverPlugin(...)), while example apps that need no custom options set OS_DATABASE_URL and let os dev build the driver). Both routes are on the rewritten page.

H2 — full-page audit

Every claim checked is tabulated in the PR body, OK verdicts included. OK: the line-43 import, line-137 IDataDriver subpath, getKnex(), options.bypassTenantAudit / OS_TENANT_AUDIT=0, the tenant-scope matrix, engine.execute(sql), both sibling-driver links, and the Knex.Config option names. Wrong: DriverSQL.configure() ×3 (the card's finding), defineStack({ driver: … }) ×6, driver.raw() ×6 (it is execute()), checkConnection() ×2 (it is checkHealth(), which resolves false rather than throwing — so the try/catch was wrong in shape too), destroy() (it is disconnect()), transaction(cb) + trx.insert({ object, data }) (real seam is beginTransaction() + options.transaction + commit()/rollback()), kernel.getDriver() ×3 (no such member; the engine's getDriver is private), the query AST in three places (object name is argument one; filter key is where with the ObjectQL dialect; sorting is orderBy: [{ field, order }] — sort/direction is the retired alias SortNodeSchema itself names), interface SQLDriverConfig (the export is SqlDriverConfig, and all four ObjectStack keys were undocumented), tenancy.strategy, configs[env], top-level ssl, the objectstack_* table names ×12, the knex-CLI migration workflow, the inverted "never raw DDL" best practice, the knex index migration, and a dead @vercel/postgres import.

H3 — runnability

Worse than a wrong method name, exactly the class the dispatch pointed at: two config blocks on this page could not load at all. Both driver: and tenancy.strategy throw at defineStack(), measured by execution, not inference. A third, quieter failure: every raw-SQL example queried objectstack_-prefixed tables, but StorageNameMapping.resolveTableName makes the physical table name the namespace-prefixed object name (crm_account, sys_user) — 12 occurrences naming tables that never exist. No undocumented env var is required by this page's own configs (unlike the mcp case): the driver is constructed with an explicit config, so the gap does not reproduce here.

H4 — line 137 confirmed

import type { IDataDriver } from '@objectstack/spec/contracts' still resolves — ./contracts is a declared subpath, and the isolated probe compiles at exit 0. No regression: check:published-readme-exports is green on a fully built tree with the baseline still at entries: [], and it now reads more of this page than before, because fences that previously imported nothing now carry real imports.
