+# MemPalace v3.0.0 — Ezra Integration Packet
+
+This packet turns issue #570 into an executable, reviewable integration plan for Ezra's Hermes home.
+It is a repo-side scaffold: no live Ezra host changes are claimed in this artifact.
+
+## Commands
+
+```bash
+pip install mempalace==3.0.0
+mempalace init ~/.hermes/ --yes
+cat > ~/.hermes/mempalace.yaml <<'YAML'
+wing: ezra_home
+palace: ~/.mempalace/palace
+rooms:
+  - name: sessions
+    description: Conversation history and durable agent transcripts
+    globs:
+      - "*.json"
+      - "*.jsonl"
+  - name: config
+    description: Hermes configuration and runtime settings
+    globs:
+      - "*.yaml"
+      - "*.yml"
+      - "*.toml"
+  - name: docs
+    description: Notes, markdown docs, and operating reports
+    globs:
+      - "*.md"
+      - "*.txt"

+projects: []
+YAML
+echo "" | mempalace mine ~/.hermes/
+echo "" | mempalace mine ~/.hermes/sessions/ --mode convos
+mempalace search "your common queries"
+mempalace wake-up
+hermes mcp add mempalace -- python -m mempalace.mcp_server
+```
+
+## Manual config template
+
+```yaml
+wing: ezra_home
+palace: ~/.mempalace/palace
+rooms:
+  - name: sessions
+    description: Conversation history and durable agent transcripts
+    globs:
+      - "*.json"
+      - "*.jsonl"
+  - name: config
+    description: Hermes configuration and runtime settings
+    globs:
+      - "*.yaml"
+      - "*.yml"
+      - "*.toml"
+  - name: docs
+    description: Notes, markdown docs, and operating reports
+    globs:
+      - "*.md"
+      - "*.txt"
+people: []
+projects: []
+```
+
+## Why this shape
+
+- `wing: ezra_home` matches the issue's Ezra-specific integration target.
+- `rooms` split the mined material into sessions, config, and docs to keep retrieval interpretable.
+- Mining commands pipe empty stdin to avoid the interactive entity-detector hang noted in the evaluation.
+
+## Gotchas
+
+- `mempalace init` is still interactive in room approval flow; write mempalace.yaml manually if the init output stalls.
+- The yaml key is `wing:` not `wings:`. Using the wrong key causes mine/setup failures.
+- Pipe empty stdin into mining commands (`echo "" | ...`) to avoid the entity-detector stdin hang on larger directories.
+- First mine downloads the ChromaDB embedding model cache (~79MB).
+- Report Ezra's before/after metrics back to issue #568 after live installation and retrieval tests.
+
+## Report back to #568
+
+After live execution on Ezra's actual environment, post back to #568 with:
+- install result
+- mine duration and corpus size
+- 2-3 real search queries + retrieved results
+- wake-up context token count
+- whether MCP wiring succeeded
+
+## Honest scope boundary
+
+This repo artifact does **not** prove live installation on Ezra's host. It makes the work reproducible and testable so the next pass can execute it without guesswork.
