+# Local Agent Smoke Runbook
+
+This runbook is for agent builders who want to prove that a local EverOS
+service can be used safely by more than one runtime, such as a coding
+assistant, a CLI agent, a desktop app, or a local orchestrator.
+
+The goal is deliberately narrow:
+
+1. write one scoped memory into a temporary local root;
+2. force the markdown -> LanceDB index to catch up;
+3. read the same memory from a second process;
+4. delete the source markdown in the temporary root;
+5. prove `/get` and `/search` no longer return it.
+
+Use this before wiring EverOS into any automatic post-session hook. A
+manual smoke test is cheaper than debugging an agent that silently wrote
+to the wrong scope.
+
+## Assumptions
+
+- You have already installed and configured EverOS. See
+  [QUICKSTART.md](../QUICKSTART.md).
+- The server runs on the default loopback address,
+  `http://127.0.0.1:8000`.
+- The smoke uses a throwaway `EVEROS_MEMORY__ROOT`, so deleting the test
+  markdown is safe.
+- EverOS has no built-in authentication. Keep the server on loopback
+  unless you place your own gateway in front. See
+  [SECURITY.md](../SECURITY.md).
+
+## 0. Keep loopback traffic off proxies
+
+Many agent runtimes inherit `HTTP_PROXY` / `HTTPS_PROXY` from the
+developer shell. Make sure local EverOS traffic stays local:
+
+```bash
+export NO_PROXY="${NO_PROXY:+$NO_PROXY,}127.0.0.1,localhost,::1"
+export no_proxy="${no_proxy:+$no_proxy,}127.0.0.1,localhost,::1"
+curl --noproxy '*' http://127.0.0.1:8000/health
+```
+
+If the health check hangs only inside one agent runtime, check its proxy
+environment first.
+
+## 1. Start an isolated local root
+
+Terminal A:
+
+```bash
+export EVEROS_MEMORY__ROOT="$(
+  python3 -c 'import tempfile; print(tempfile.mkdtemp(prefix="everos-agent-smoke-"))'
+)"
+echo "$EVEROS_MEMORY__ROOT"
+export EVEROS_MEMORY__TIMEZONE=UTC
+everos server start --host 127.0.0.1 --port 8000
+```
+
+Using Python's `tempfile` avoids the `mktemp` flag/template differences
+between GNU and BSD/macOS environments.
+
+Terminal B:
+
+```bash
+export EVEROS_MEMORY__ROOT="<same value printed in Terminal A>"
+export BASE_URL="http://127.0.0.1:8000"
+export APP_ID="agent_smoke_app"
+export PROJECT_ID="agent_smoke_project"
+export USER_ID="agent_smoke_user"
+export SESSION_ID="agent_smoke_session_$(date +%s)"
+export NO_PROXY="${NO_PROXY:+$NO_PROXY,}127.0.0.1,localhost,::1"
+curl --noproxy '*' "$BASE_URL/health"
+```
+
+Expected:
+
+```json
+{"status":"ok"}
+```
+
+## 2. Write and flush one memory
+
+```bash
+TS=$(($(date +%s)*1000))
+curl --noproxy '*' -sS -X POST "$BASE_URL/api/v1/memory/add" \
+  -H 'Content-Type: application/json' \
+  -d "{
+    \"session_id\": \"$SESSION_ID\",
+    \"app_id\": \"$APP_ID\",
+    \"project_id\": \"$PROJECT_ID\",
+    \"messages\": [
+      {
+        \"sender_id\": \"$USER_ID\",
+        \"role\": \"user\",
+        \"timestamp\": $TS,
+        \"content\": \"Agent smoke marker: EverOS should remember that this runtime prefers local-first memory.\"
+      },
+      {
+        \"sender_id\": \"$USER_ID\",
+        \"role\": \"assistant\",
+        \"timestamp\": $((TS+1000)),
+        \"content\": \"Acknowledged. This is a scoped local smoke test, not production memory.\"
+      }
+    ]
+  }"
+
+curl --noproxy '*' -sS -X POST "$BASE_URL/api/v1/memory/flush" \
+  -H 'Content-Type: application/json' \
+  -d "{
+    \"session_id\": \"$SESSION_ID\",
+    \"app_id\": \"$APP_ID\",
+    \"project_id\": \"$PROJECT_ID\"
+  }"
+```
+
+`/flush` is strong with respect to markdown persistence: when it returns
+`status: "extracted"`, the episode markdown is on disk. `/search` and
+`/get` read LanceDB, which is eventually consistent, so force the queue
+before asserting read-your-write:
+
+```bash
+everos cascade sync
+```
+
+## 3. Read from another runtime
+
+Open a different terminal, coding assistant, or local process. Reuse only
+the target identifiers, not the previous process state:
+
+```bash
+export BASE_URL="http://127.0.0.1:8000"
+export APP_ID="agent_smoke_app"
+export PROJECT_ID="agent_smoke_project"
+export USER_ID="agent_smoke_user"
+export NO_PROXY="${NO_PROXY:+$NO_PROXY,}127.0.0.1,localhost,::1"
+
+curl --noproxy '*' -sS -X POST "$BASE_URL/api/v1/memory/search" \
+  -H 'Content-Type: application/json' \
+  -d "{
+    \"user_id\": \"$USER_ID\",
+    \"app_id\": \"$APP_ID\",
+    \"project_id\": \"$PROJECT_ID\",
+    \"query\": \"local-first memory preference\",
+    \"top_k\": 5
+  }"
+```
+
+Pass criteria:
+
+- the response includes at least one `episodes[]` item;
+- the episode belongs to `agent_smoke_user`;
+- the summary or episode text contains the smoke marker;
+- the result stays inside `agent_smoke_app` / `agent_smoke_project`.
+
+For browsing instead of ranked recall:
+
+```bash
+curl --noproxy '*' -sS -X POST "$BASE_URL/api/v1/memory/get" \
+  -H 'Content-Type: application/json' \
+  -d "{
+    \"user_id\": \"$USER_ID\",
+    \"app_id\": \"$APP_ID\",
+    \"project_id\": \"$PROJECT_ID\",
+    \"memory_type\": \"episode\"
+  }"
+```
+
+## 4. Delete source markdown and prove absence
+
+Markdown is the source of truth; SQLite and LanceDB are derived indexes.
+For this isolated smoke root, remove the generated episode markdown and
+then force cascade to reconcile the deletion:
+
+```bash
+EPISODE_DIR="$EVEROS_MEMORY__ROOT/$APP_ID/$PROJECT_ID/users/$USER_ID/episodes"
+find "$EPISODE_DIR" -type f -name 'episode-*.md' -print -delete
+everos cascade sync
+```
+
+If `find` prints no episode file, stop and debug the write/flush step before
+asserting deletion behavior.
+
+Now prove both browse and search paths no longer return the deleted
+episode:
+
+```bash
+curl --noproxy '*' -sS -X POST "$BASE_URL/api/v1/memory/get" \
+  -H 'Content-Type: application/json' \
+  -d "{
+    \"user_id\": \"$USER_ID\",
+    \"app_id\": \"$APP_ID\",
+    \"project_id\": \"$PROJECT_ID\",
+    \"memory_type\": \"episode\"
+  }"
+
+curl --noproxy '*' -sS -X POST "$BASE_URL/api/v1/memory/search" \
+  -H 'Content-Type: application/json' \
+  -d "{
+    \"user_id\": \"$USER_ID\",
+    \"app_id\": \"$APP_ID\",
+    \"project_id\": \"$PROJECT_ID\",
+    \"query\": \"local-first memory preference\",
+    \"top_k\": 5
+  }"
+```
+
+Pass criteria:
+
+- `/get` returns `count: 0` or an empty `episodes` array for the smoke
+  scope;
+- `/search` returns no `episodes[]` item containing the smoke marker;
+- `everos cascade status` shows no stuck pending or failed row for the
+  deleted markdown path.
+
+## What not to infer
+
+- A passing smoke does not mean automatic session hooks are safe. It only
+  proves the local service, scope ids, index catch-up, and absence path.
+- Do not inspect `system.db` for memory content. SQLite stores state,
+  buffers, audit, and the cascade queue; the durable user-visible memory
+  is markdown, and search state is derived into LanceDB.
+- Do not treat old cloud plugin examples as the current OSS integration
+  contract. The supported local OSS API is documented in
+  [api.md](api.md) and [migration-to-1.0.0.md](migration-to-1.0.0.md).
