Issue Number: close #499

Background

This touches the OpenCode and Pi integration packages. The governing public contract is integrations.json: OpenCode exposes native nowledge_mem_* tools over CLI+HTTP, while Pi injects startup context and calls nmem through its extension. Ambient Space config should remain the default lane, but a user-named Space needs to be expressible on a single tool call.

What problem does this PR solve?

OpenCode tools did not expose per-call space or space_id arguments. When a user asked for a different Space, for example “search in Marketing”, the agent had no native tool field for that request and could silently use the ambient Space instead. Pi also only checked for --space, so a future explicit --space-id command could still receive an extra ambient --space.

How does it work?

  • Adds shared OpenCode tool args for space and space_id; space_id wins when both are present.
  • Routes CLI-backed tools with --space-id or --space, and prevents ambient injection when either explicit flag is already present.
  • Routes manual OpenCode full-session capture through the same explicit Space on both create and append paths.
  • Keeps automatic capture and ambient NMEM_SPACE / shared-config behavior unchanged when no explicit Space is supplied.
  • Updates OpenCode/Pi versions, changelogs, README guidance, registry metadata, and the generated OpenCode dist/index.js.
  • Fixes the existing Claude/Grok public registry and marketplace version metadata to match the already-bumped 0.7.23 plugin manifest.

Tests

  • npm run check in nowledge-mem-opencode-plugin -> esbuild generated dist/index.js; node --check dist/index.js passed.
  • pytest community/tests/plugin_e2e/test_key_plugins_e2e.py from the mem parent workspace -> 24 passed, 6 skipped.

Side effects / risks

  • Changes package versions for OpenCode (0.3.7) and Pi (0.8.6).
  • Does not change the core Mem server or storage behavior.
  • Does not change automatic OpenCode/Pi ambient capture semantics; explicit Space only applies when the tool call supplies it.

Estimated code review effort: 3 (Moderate) | ~20 minutes

Mergeability Score: 🟡 Moderate · up to 61258

Explicit Space saves can cause a subsequent ambient session capture to be skipped, leaving expected thread data missing from the ambient Space. Merge should wait for the deduplication fix or explicit owner acceptance of this bounded data-correctness risk.

CLI emits invalid space-id flag

High Severity

explicitSpaceForCli sends tool space_id as --space-id, but the CLI contract and every other integration route both names and ids through --space. Agent guidance prefers space_id after spaces list, so those calls can fail unrecognized-argument errors instead of routing the Space.

Exercise routing behavior and verify the shipped entry point.

These assertions inspect source text and the main value. They do not execute withExplicitSpaceArg, withAmbientSpaceArg, syncSessionThread, or the Pi command builder. They also do not verify that dist/index.js exists or contains the generated OpenCode implementation. Add mocked CLI and HTTP cases for space_id precedence, explicit --space and --space-id suppression, create/append routing, and Pi preservation. Assert that the declared OpenCode entry point exists after the build.

Scope automatic-capture deduplication by Space.

SessionSyncState remains keyed only by sessionID, and lastSignature is updated after every successful sync. If a manual nowledge_mem_save_thread call uses an explicit space or space_id before the idle hook runs, the subsequent ambient sync sees the same signature and returns already_synced. The ambient thread is then not captured. Store the last signature per effective Space, or do not update ambient state for explicit manual saves.

Proposed fix
 type SessionSyncState = {
   timer?: ReturnType<typeof setTimeout>
   inFlight?: Promise<void>
   pending?: boolean
-  lastSignature?: string
+  lastSignatureBySpace?: Map<string, string>
 }

+const effectiveSpace = options.spaceId ?? ambientSpaceId ?? "default"
 const state = syncStateFor(ctx.sessionID)
-if (!options.force && state.lastSignature === signature) {
+if (!options.force && state.lastSignatureBySpace?.get(effectiveSpace) === signature) {
   return { skipped: true, reason: "already_synced", session_id: ctx.sessionID }
 }

-state.lastSignature = signature
+(state.lastSignatureBySpace ??= new Map()).set(effectiveSpace, signature)
