Honcho memory plugin missing publicArtifacts capability for Wiki Bridge mode

Summary

When using openclaw-honcho as the active memory plugin slot (plugins.slots.memory = "openclaw-honcho"), the Wiki Bridge reports zero exported artifacts even though:

• Honcho is healthy and running (Docker services up, PostgreSQL/Redis/Deriver all operational)
• Memory data exists across workspaces (session exports, daily notes, etc.)
• The documented QMD + bridge-mode hybrid setup is configured correctly
• memory-wiki in bridge mode successfully imports artifacts when using memory-core as the slot

The root cause appears to be that Honcho does not implement or expose the publicArtifacts.listArtifacts capability that the Wiki Bridge plugin SDK expects from the active memory plugin.

Expected behavior

When plugins.entries["memory-wiki"].config.vaultMode = "bridge" and plugins.slots.memory = "openclaw-honcho":

• openclaw wiki status should report nonzero bridgePublicArtifactCount
• openclaw wiki bridge import should detect and import artifacts from Honcho workspaces
• The Wiki Bridge should be able to compile Honcho memory data (session exports, daily notes, dream reports) into durable wiki pages

Actual behavior

Wiki vault mode: bridge
Bridge: enabled (0 exported artifacts)
Pages: 1 sources, 0 entities, 0 concepts, 8 syntheses, 10 reports

Warning: Bridge mode is enabled but the active memory plugin is not exporting any public memory artifacts yet.

openclaw wiki bridge import --json:

{
  "importedCount": 0,
  "updatedCount": 0,
  "skippedCount": 0,
  "removedCount": 0,
  "artifactCount": 0,
  "workspaces": 0
}

Configuration (our setup)

{
  plugins: {
    slots: { memory: "openclaw-honcho" },  // ← HONCHO NOT memory-core
    entries: {
      "memory-wiki": {
        enabled: true,
        config: {
          vaultMode: "bridge",
          bridge: { enabled: true, readMemoryArtifacts: true, followMemoryEvents: true, indexDreamReports: true },
          search: { backend: "shared", corpus: "all" }
        }
      },
      "openclaw-honcho": {
        enabled: true,
        config: { baseUrl: "http://localhost:8000", apiKey: "...", workspaceId: "openclaw" }
      }
    }
  },
  memory: { backend: "qmd" }  // ← QMD as active memory backend
}

Related issues (for memory-core, NOT Honcho)

These issues describe the same symptom but for memory-core as the memory slot:

• [Bug]: memory-wiki bridge imports 0 artifacts from memory-core #63092 — "memory-wiki bridge imports 0 artifacts from memory-core"
• [Bug]: memory-wiki bridge import reports 0 exported artifacts because memory capability publicArtifacts is not restored on cached plugin registry loads #65698 — "bridge import reports 0 exported artifacts because memory capability publicArtifacts is not restored on cached plugin registry loads"
• [Bug] openclaw wiki bridge import always returns 0 artifacts — CLI does not initialize memory-core plugin runtime #65722 — "openclaw wiki bridge import always returns 0 artifacts — CLI does not initialize memory-core plugin runtime"
• memory-wiki bridge mode reports zero public artifacts and can remove existing bridge pages even when QMD memory is healthy #65976 — "bridge mode reports zero public artifacts and can remove existing bridge pages even when QMD memory is healthy"

This issue is specifically about Honcho, which has never been tested for the publicArtifacts capability. The fix for memory-core (forced registration into memory-state singleton) may not apply to Honcho since it's a Dockerized service with different architecture.

Proposed solution

1. Add publicArtifacts.listArtifacts capability to Honcho — expose an endpoint or SDK method that returns exported memory artifacts in the format expected by Wiki Bridge
2. Register this capability via registerMemoryCapability() in the OpenClaw plugin SDK
3. Update documentation to clarify that not all memory plugins support bridge mode out of the box

Workaround (for our setup)

Until Honcho implements this capability, use isolated mode for Wiki:

plugins.entries["memory-wiki"].config.vaultMode = "isolated"  // instead of "bridge"

Or manually maintain wiki pages via wiki_apply as we've been doing. This is functional but loses the automated bridge sync.

Impact

• The recommended QMD + Honcho + Wiki Bridge hybrid setup (documented in OpenClaw docs) does NOT work when using Honcho as the memory slot
• Users following the documented pattern will encounter "0 exported artifacts" and have no clear path forward
• This is a missing capability, not a configuration issue

Environment

• OpenClaw version: 2026.5.7
• Memory backend: QMD
• Active memory plugin: openclaw-honcho (Dockerized)
• Wiki mode: bridge
• Honcho services: API, PostgreSQL, Redis, Deriver, Prometheus, Grafana — all running
