摘要 / Summary

An online embedding server could make Test status claim that a nonexistent model was usable, even with 100% historical vector coverage. Require Mnemon CLI 0.2.13+ for this check, consume its actual embedding_available model probe without falling back to provider reachability, and show model availability accurately in English and Chinese.

关联 Issue 或背景 / Related Issue or Context

Fixes #494. The CLI implementation was already fixed in mnemon-dev/mnemon#173 and released in v0.2.13. This PR handles older installed binaries and the plugin status presentation; it does not duplicate the provider probe.

兼容性与数据安全 / Compatibility and Data Safety

Only Test status requires a recognized stable CLI version >=0.2.13. Older/custom unrecognized binaries receive an actionable upgrade error; other commands and coverage-only backfill counting retain legacy compatibility. The effective CLI is checked on every explicit test, so updating or rolling back the executable does not reuse a stale success. No storage format, credential, process environment, permission or memory mutation changes. The upstream synthetic probe sends no stored memories and uses the configured provider's normal billing/timeout behavior. Existing vector coverage does not establish compatibility with a newly selected model. Includes a patch changeset for Memory Spaces and synchronized guides.

本地验证 / Local Validation

执行的命令 / Commands run:

pnpm run verify
pnpm exec vitest run plugins/dsh-mnemon-source-memory-spaces/tests/service.spec.ts tests/client-settings.spec.tsx

结果摘要 / Result summary:

• Six new service regressions failed before the fix because legacy status was accepted. They pass after the fix, including upgrade/rollback, malformed responses and reachability-versus-model semantics.
• Full final pnpm run verify passed: root 2,245 passed / 7 skipped, all plugin suites, deterministic builds, real Headless activation and package validation. The first run identified the expected bilingual-copy fingerprint change; the reviewed baseline was updated and the full command rerun successfully.
• Real old/new CLI and UI checks are recorded below.

用户可见变更证据 / Local Feature Evidence

In an isolated real DSH 0.2.1-rc.2 Web profile with this branch built, set the saved endpoint to a loopback fixture that returns model-not-found and the model to missing-model; click Apply then Test status. The visible result was 嵌入模型不可用 · missing-model · 协议 ollama · 已嵌入 0/0（0%）. A local screenshot was captured; no real account, secret or memory was used.

Real CLI smoke results, through the Memory Spaces service, using disposable stores with one synthetic memory and 100% stored coverage:

Protocol	CLI 0.2.12 missing-model raw result	Plugin with 0.2.12	CLI 0.2.13 healthy	CLI 0.2.13 missing model	CLI 0.2.13 unreachable endpoint
Ollama	available=true	upgrade required	available=true	available=false, coverage=100%	available=false
OpenAI-compatible	available=true	upgrade required	available=true	available=false, coverage=100%	available=false

The downloaded 0.2.13 archive was checked against its published SHA-256 before running it.
