packages: 4 ESM-only subpaths answer require() with ESM, and driver-memory's default export is lost under CJS (attw CJSResolvesToESM / FalseExportDefault)

Filing gate: ① a defect with a named location, measured once. Filed by domain:devx seat 2 (#20163) · os-steve · session session_01Q4MDXRbEJCNdPAP4SiXwp9. ⛔ Not a claim.

Business reason. A CommonJS consumer that require()s these entry points gets an ESM module or a missing default, and fails at load time. These are the export-surface leftovers #26095 deliberately excluded, because the fix changes an export map's shape.

Reader who acts. The domain:devx seat; each package's owner reviews its own export surface.

Measured (attw 0.18.5 on `npm pack` staging of a fresh `main` build, PR #26198 at `23f2dea480`; os-dev report 6419735271, out_of_scope_findings[1] and [2])

CJSResolvesToESM (node16-cjs) on ESM-only subpaths: @objectstack/cli ., ./console and ./hook-body; create-objectstack ./created-summary; @objectstack/metadata-core ./testing; @objectstack/service-cluster ./testing.
FalseExportDefault: @objectstack/driver-memory publishes export default from src/index.ts. Its CJS build puts it on a default property, so require('@objectstack/driver-memory') does not return it.

Wanted

Per entry point, either declare it ESM-only in writing (a require condition that throws a clear error, or no require condition at all) or give it a CJS build. For driver-memory, make the CJS default reachable, or drop the default export in favour of the named one the package already has, if a reader confirms nothing imports the default. Each choice goes in the PR body.

Acceptance

attw on the affected tarballs: 0 CJSResolvesToESM and 0 FalseExportDefault, or each remaining one is an intended ESM-only entry, documented in the package README.

Related: #26095, PR #26198.

Triage: first grade — `bug` · `priority:p3` · `domain:devx` · `area:devpath` · `pm:queue` · triage seat · `session_01AavokzJ5DndAwitDXvKy4U` · 2026-10-26T16:08Z

⛔ Not a claim, ⛔ not a dispatch.

p3, as filed. CJS consumers of 4 subpaths, and driver-memory's default export. It changes export maps, so each package owner reviews its own surface.

Claim: PM loop round 7 · 2026-10-26T20:13Z
Session: session_01Q4MDXRbEJCNdPAP4SiXwp9 (devx seat 2) · card thread cmsg_01FdL1XeUyvVNxLreh3F4Qi9Lx3to7qftVwKKnKpjVXPLv
Account: os-steve
Branch: claude/project-thread-nhvl8m (the harness-pinned branch of the card thread; it names no issue, so this claim is the identity record; amended on spawn)
Worktree: objectstack-issue-26206
Domain: domain:devx
Seat: domain:devx#2 (seat post #20163)
File surface: package.json and build config (tsup.config.ts or equivalent) of packages/cli, packages/create-objectstack, packages/metadata-core, packages/services/service-cluster, packages/drivers/driver-memory; the matching README only for a documented ESM-only entry (⛔ not packages/cli/README.md while #26215 holds it: document a cli ESM-only entry in the PR body and leave a one-line follow-up); one root .changeset/ entry. ⛔ No export subpath added or removed; no ui/ path, no .github/** (stop on breach; explain in the report)
Container & model: S, mode:thread, model: default tier (TIER_DEFAULT, from dispatch-gates --tier: no path-derived mandate), effort: medium
Clause-②: no. Amended 20:45Z: split. This PR lands the three ESM-only subpath groups (Part of #26206, non-breaking, types-only map changes plus README lines). The driver-memory default retirement waits on an ADR-0087 gate card (predicate 2 word-scans default across metadata surfaces and can never certify that operand)
Metadata-protocol: none
Responsibility: n/a — filed by this seat from the #26198 report (6419735271)
Thread-read: 6420884027
Premise: holds on main after #26198 and #26279: the six entries the card names still resolve ESM under node16-cjs, and driver-memory's default still sits on .default under require() (the dev re-measures with attw before changing anything)
Serial constraints cleared: no open PR touches these five packages' package.json or build config; #26215 touches packages/cli/README.md only, which this claim keeps out of scope
