Priority: ➖ Normal Estimated code review effort: 2 (Simple) | ~10 minutes Change: Bug fix · Severity of issue fixed: Medium Suggested reviewers: Merge Risk: ⚪ Minimal · up to Extensions can load without locally available TUI metadata while unverified default editors remain rejected. The host-certified path remains available; the remaining concern is a focused regression-test gap, not an established runtime blocker. Security Architecture ReviewSecurity architecture risk: ⚪ Minimal · up to Unavailable metadata no longer blocks module loading, while unsupported or unverified editors remain rejected before private editor state is accessed.

- Around line 180-193: Add a module-isolated test around
`createVimEditorAdapter` for the case where `pi-tui` metadata is unavailable at
module load. Verify the default `Editor` is rejected for `"0.99.1"` without
trusted metadata; keep the existing host path that passes `runtime.version` as
`verifiedVersion` separate.

Exercise the default adapter with unavailable metadata.
readTuiVersion(missing) only tests the helper. IMPORTED_TUI_VERSION remains captured at module load. The adapter assertion uses "unknown", which fails the supported-version check before metadata validation. This test can pass if the default Editor is incorrectly accepted for "0.99.1" when metadata is unavailable. Add a module-isolated test for that case. The host path separately passes runtime.version as verifiedVersion.

Closes #1592
Problem
lib/vim-editor-adapter.tsread@earendil-works/pi-tui/package.jsonat module load withcreateRequire(import.meta.url).pi-tuiis an optional peer, so installed copies of the package (for example viapi update) often lack it on disk. Pi's import alias provides it for regular imports, butcreateRequirebypasses that alias. The resulting throw preventsgentle-agentsandgentle-shellfrom loading.Fix
readTuiVersion()helper that returnsundefinedwhen the metadata cannot be resolved.IMPORTED_TUI_VERSIONis missing, the defaultEditorpath inhasEditorIdentitystays unauthorized (fail closed), which matches the adapter's existing contract.resolveVimRuntimestill certifies the host pair and passesverifiedVersion.Tests
TUI metadata lookup fails closed when pi-tui is only host-provided. It was RED (missing export) before the fix and is GREEN after.tests/vim-editor-adapter.test.ts: 36 pass / 5 fail. The same 5resolveVimRuntime/ installed-pair tests also fail onmainin my local environment (freshnpm install, no lockfile), so they appear unrelated to this change.tsc --noEmitreports the same error count before and after the change.Summary by CodeRabbit
