fix(memory): handle block-list content in remove_code_blocks

A custom LangChain LLM passed to AsyncMemory._create_procedural_memory
returns AIMessage.content, which is str | list[str | dict]. Providers
that emit content blocks hit content.strip() on a list and raised
AttributeError.

remove_code_blocks already normalized None, so the list case is handled
in the same guard rather than at the single call site.

Closes #6150

+pnpm install
+pnpm run build        # tsup (ESM)
+pnpm run lint         # biome check src/
+pnpm run lint:fix     # biome check --write src/

+```
+
+pnpm only. Never npm, never yarn.
+
+## Conventions
+
+> **Biome, not ESLint. vitest, not jest.** `mem0-ts/` uses Prettier + jest and
+> `integrations/vercel-ai-sdk/` uses ESLint + jest. Running those tools here produces
+> spurious diffs. Every toolchain in this repo is per-package.
+
+- **Node 18+** required.
+- **Build:** tsup, ESM output only.
+- **Linter and formatter:** Biome, configured in `biome.json`.
+- **Tests:** vitest.
+- **TypeScript strict mode.** ES module `import` syntax only, never `require()`.
+
+Run `pnpm run typecheck` after every change.
+
+## Dependencies
+
+Commander + Chalk + ora + cli-table3, and `mem0ai` (npm) for API calls.
+
+## CI and release
+
+- CI: `cli-node-ci.yml`, Biome + tsc + vitest + tsup build on Node 20 and 22.
+- Release: tag prefix `cli-node-v*` dispatches `cli-node-cd.yml`, publishing to npm over OIDC.

+# Python CLI (`cli/python/`)
+
+The `mem0-cli` package on PyPI. Typer-based, entry point `mem0`.
+
+## Commands
+
+```bash
+pip install -e ".[dev]"   # dev install: ruff + pytest
+ruff check .              # lint
+ruff format .             # format
+pytest                    # test
+hatch build               # build
+```
+
+## Conventions
+
+> **Line length is 100 here, not 120.** The root Python SDK uses 120. Running the root
+> `make format` over this directory reformats every file and fails CI. Use the local
+> `ruff` invocations above.
+
+- **Python 3.10+.** Not 3.9, unlike the root SDK.
+- **Ruff** with an extended rule set: `E`, `F`, `I`, `W`, `UP`, `B`, `SIM`, `RUF`.
+  Ignores `E501` (formatter handles it), `B008` (required by Typer's argument defaults),
+  and `SIM108`.
+- **Ruff format:** double quotes, space indent, `docstring-code-format = true`.
+- **isort** first-party is `mem0_cli` only.
+- **pytest** for tests.
+- Target version pinned to `py310`.
+
+## Layout
+
+```
+cli/python/
+├── src/mem0_cli/     package source (src layout)
+└── tests/
+```
+
+Entry point: `mem0 = "mem0_cli.app:main"`.
+
+## Dependencies
+
+Typer + Rich + httpx. `mem0ai` is **optional**, exposed through the `[oss]` extra for OSS mode. Do not promote it to a required dependency.
+
+## CI and release
+
+- CI: `cli-python-ci.yml`, ruff + pytest + `hatch build` on Python 3.10, 3.11, 3.12.
+- Release: tag prefix `cli-v*` dispatches `cli-python-cd.yml`, publishing to PyPI over OIDC.

+
+**Bug Fixes:**
+- **Core:** Percent-escape `%`, `&`, and `=` in `user_id`, `agent_id`, and `run_id` when building the session scope key for the recent-conversation buffer, so the key stays unambiguous for ids containing those characters. Ordinary ids keep their existing key; an id already containing `%`, `&`, or `=` maps to a new key, so its buffer starts empty once and refills on the next `add()`. Stored memories are unaffected ([#6892](https://github.com/mem0ai/mem0/pull/6892))
+- **Vector Stores:** Raise `ValueError` when a PGVector `in`/`nin` filter value is not a list. A string value was previously iterated character by character into the generated `= ANY(...)` array (so `{"user_id": {"in": "alice"}}` matched `a`, `l`, `i`, `c`, `e`), and a non-iterable value raised a bare `TypeError` from deep inside filter building ([#6879](https://github.com/mem0ai/mem0/pull/6879))
+- **Vector Stores:** Reject `index_accuracy=0` in the Oracle AI Vector Search config. The range check sat behind a truthiness test, so `0` skipped validation entirely and was passed through to `WITH TARGET ACCURACY 0` instead of raising ([#6848](https://github.com/mem0ai/mem0/pull/6848))
+- **Vector Stores:** Close the Oracle connection or pool that Mem0 opened when initialization fails. A client version check, a database version check, or a `create_col()` error previously propagated with the connection still open, leaking it for the life of the process. A caller-supplied `client` is left untouched ([#6839](https://github.com/mem0ai/mem0/pull/6839))
+

+
+<Update label="2026-08-05" description="v2.0.17">
+
+**New Features:**
+- **Client:** Add `agent_custom_instructions` to `project.update()`/`update_project()` (sync and async) and to the `ProjectUpdateOptions` and `AddMemoryOptions` typed models. It sets a second extraction instruction set that applies only to agent-scoped memories: an add passing `agent_id` without `user_id` uses it, one passing both splits by attribution, and while it is unset `custom_instructions` continues to apply to every memory ([#6809](https://github.com/mem0ai/mem0/pull/6809))

+
+<Update label="2026-08-04" description="v2.0.16">
+
+**New Features:**
+- **Client:** Add `reference_date`, `latest_only`, and `keyword_search` to `SearchMemoryOptions`, and `latest_only` to `GetAllMemoryOptions`, keeping the Python client's typed options in sync with the Platform API and the CLIs ([#6696](https://github.com/mem0ai/mem0/pull/6696))
+
+**Bug Fixes:**
+- **Core:** Stop `add()` metadata from setting a memory's identity scope. `_build_filters_and_metadata()` now strips `user_id`, `agent_id`, `run_id`, and `actor_id` from caller-supplied `metadata` before building the creation template, so metadata can no longer place a memory into a scope that was never passed through the entity params ([#6656](https://github.com/mem0ai/mem0/pull/6656))
+- **Vector Stores:** Validate Upstash filter keys and values in `search()`, `keyword_search()`, and `list()`. Filter keys must match a safe identifier pattern, values must be `str`/`int`/`float`/`bool`, and string values containing a double quote or backslash are now rejected instead of being interpolated unescaped into the generated query string ([#5981](https://github.com/mem0ai/mem0/pull/5981))
+- **Embeddings:** `FastEmbedEmbedding.embed()` now converts its result with `.tolist()` before returning, so callers get a plain `List[float]` instead of a numpy array ([#6770](https://github.com/mem0ai/mem0/pull/6770))
+- **Embeddings:** `HuggingFaceEmbedding` now passes `api_key` to the OpenAI-compatible client when `huggingface_base_url` is set. The configured key was previously dropped, so the client fell back to `OPENAI_API_KEY` from the environment or raised `OpenAIError` at construction when that was unset ([#6770](https://github.com/mem0ai/mem0/pull/6770))
+- **Embeddings:** Replace Ollama's interactive `pip install` prompt on import with a plain `ImportError`. Importing `mem0.embeddings.ollama` without the `ollama` package previously blocked on stdin and then called `sys.exit(1)`, killing the host process instead of raising ([#6770](https://github.com/mem0ai/mem0/pull/6770))
+- **Core:** `remove_code_blocks()` now returns an empty string for `None` input instead of raising `AttributeError` ([#6770](https://github.com/mem0ai/mem0/pull/6770))
+- **Core:** `parse_vision_messages()` now chains the original exception (`raise ... from e`) when an image download fails, so the root cause is preserved in the traceback ([#6770](https://github.com/mem0ai/mem0/pull/6770))
+- **Core:** `process_telemetry_filters(None)` now returns `([], {})`, matching the two-value tuple every caller unpacks, instead of `{}` ([#6770](https://github.com/mem0ai/mem0/pull/6770))
+- **Core:** `LlmFactory.create()` no longer mutates the caller's config dict in place via `.update(kwargs)`; the merge now builds a new dict ([#6770](https://github.com/mem0ai/mem0/pull/6770))
+- **Rerankers:** The Cohere, HuggingFace, SentenceTransformer, and Zero Entropy rerankers' failure-fallback path no longer mutates the caller's document dicts in place when stamping `rerank_score`; it now falls back on copies ([#6770](https://github.com/mem0ai/mem0/pull/6770))
+- **Vector Stores:** Remove `logging.basicConfig()` calls from the MongoDB and Vertex AI Vector Search providers, so selecting either provider no longer reconfigures the host application's root logger as a side effect ([#6770](https://github.com/mem0ai/mem0/pull/6770))

Stored memories are unaffected ([#6892](https://github.com/mem0ai/mem0/pull/6892))
+- **Vector Stores:** Close and clear the Oracle pool that Mem0 created when `initialize()` fails, and reset the cached init promise so the next call retries instead of replaying the rejection forever. A caller-supplied `client` is left untouched ([#6839](https://github.com/mem0ai/mem0/pull/6839))
+- **Vector Stores:** Validate Oracle `insert()` batches before touching the database: `ids` and `payloads` must match `vectors` in length, so a short array can no longer write rows with `undefined` ids or silently drop payloads ([#6839](https://github.com/mem0ai/mem0/pull/6839))
+
+**Improvements:**
+- **Vector Stores:** Cut Oracle round trips. `insert()` now sends the whole batch through one `executeMany()` with explicit `bindDefs` instead of one `INSERT` per vector, `list()` reads the total from a `COUNT(*) OVER ()` window in the same statement instead of issuing a second count query, and an unfiltered `search()` adds the `VECTOR_INDEX_TRANSFORM` hint so the vector index is used ([#6835](https://github.com/mem0ai/mem0/pull/6835))

+
+**Bug Fixes:**
+- **Client:** Take the `/v1/ping/` identity/telemetry call off the request critical path. Every method previously did `if (this.telemetryId === "") await this.ping();`, blocking the first call on each client instance on a network round trip; the ping now resolves in the background through a shared, credentials-keyed promise cache (FIFO-capped at 50 entries), so concurrent clients on the same host/API key share one ping instead of issuing one each, and a failed ping is not cached so the process can retry ([#6788](https://github.com/mem0ai/mem0/pull/6788))
+- **Client:** `deleteUsers()` now issues its per-entity DELETE requests through the shared `fetch()`-based helper instead of the axios instance, which defaulted to `keepAlive: false`. Deleting every user, agent, app, and run now reuses pooled connections instead of paying a fresh TCP/TLS handshake per entity ([#6788](https://github.com/mem0ai/mem0/pull/6788))
+- **Memory (OSS):** Stop `add()` metadata from setting or overwriting a memory's identity scope. Metadata now runs through the same `stripIdentityKeys()` helper as `update()`, so `user_id`/`agent_id`/`run_id` (snake_case or camelCase) and `actor_id` passed in metadata can no longer place a memory into a scope the caller didn't request through `userId`/`agentId`/`runId`/`filters` ([#6377](https://github.com/mem0ai/mem0/pull/6377))
+- **Vector Stores:** Fix Redis `search()` and `list()` building an invalid, empty RediSearch filter expression when `filters` was an empty object or contained only null/undefined values. The shared `buildRedisFilterExpr()` helper now falls back to `"*"` (match all) instead of joining zero conditions into `""` ([#6014](https://github.com/mem0ai/mem0/pull/6014))

+- **`add`:** `--categories` is no longer forwarded on `add`.

-**What replaces it:**
-
-Mem0 now builds the graph itself. It extracts entities (proper nouns, quoted text, compound noun phrases) from every memory during the add pipeline and stores them in a parallel collection (`{collection}_entities`) inside your existing vector store. Memories that share an entity are linked, and at search time entities from the query are matched against this collection to boost connected memories. The boost is folded into the combined `score` on each result.
+- `graph_store` / `graphStore` configuration block
+- All external graph store drivers (Neo4j, Memgraph, Kuzu, Apache AGE, Neptune) and their code paths (~4000 lines)
 
 **Migration:**
 - Remove `enable_graph` / `enableGraph` from your config
 - Remove the `graph_store` / `graphStore` block: it is no longer read
 - Uninstall external graph drivers (neo4j, memgraph, etc.) if you were using them only for Mem0
-- No data migration is required. Built-in graph memory activates automatically on the next `add()` call.

 <Warning>
-The old `relations` field on search results (populated by the external graph store) is no longer returned. Entity connections are now applied through retrieval ranking rather than exposed as a separate, directly traversable structure. If your application read or traversed the `relations` array, you will need to redesign that part against the new API.

+## Agent Custom Instructions
+
+`custom_instructions` applies to every memory your project extracts, no matter whose it is. But what is worth remembering about an agent is rarely what is worth remembering about a user: an agent's useful memories are things like which tools fail, which retry strategies work, and how a given environment behaves, not personal preferences.
+
+`agent_custom_instructions` is an optional second set of extraction rules that applies only to agent-scoped memories.
+
+Available from Python SDK `v2.0.17` and TypeScript SDK `v3.1.5`. Upgrade first if you are on an earlier release.
+
+Set it on the project alongside `custom_instructions`:
+
+<CodeGroup>
+```python Python
+client.project.update(
+    custom_instructions="Extract the user's preferences, goals, and constraints.",
+    agent_custom_instructions=(
+        "Extract operational lessons for the agent:\n"
+        "- Tools that failed and the error returned\n"
+        "- Retry or fallback strategies that worked\n"
+        "- Environment quirks worth recalling on the next run\n\n"
+        "Exclude: user preferences, personal details."
+    ),
+)
+```
+
+```javascript JavaScript
+await client.updateProject({
+  customInstructions: "Extract the user's preferences, goals, and constraints.",
+  agentCustomInstructions: `Extract operational lessons for the agent:
+- Tools that failed and the error returned
+- Retry or fallback strategies that worked
+- Environment quirks worth recalling on the next run
+
+Exclude: user preferences, personal details.`,
+});
+```
+</CodeGroup>
+
+### Which instructions apply
+
+Which set governs an `add()` call depends on the entity IDs you pass with it:
+
+| The add call passes | Instructions applied |
+|---------------------|----------------------|
+| `user_id` only | `custom_instructions` |
+| `agent_id` only | `agent_custom_instructions` |
+| `user_id` **and** `agent_id` | `agent_custom_instructions` govern the memories attributed to the assistant; `custom_instructions` govern the rest |
+
+`agent_custom_instructions` is unset by default. While it is unset, `custom_instructions` applies to every memory, so projects that don't set it behave exactly as they did before.
+
+### Overriding for a single call
+
+Both fields are also accepted per request, overriding the project setting for that `add()` only:
+
+<CodeGroup>
+```python Python
+client.add(
+    messages,
+    filters={"agent_id": "support-agent"},
+    agent_custom_instructions="Only remember which tools errored and why.",
+)
+```
+
+```javascript JavaScript
+await client.add(messages, {
+  agentId: "support-agent",
+  agentCustomInstructions: "Only remember which tools errored and why.",
+});
+```
+</CodeGroup>
+
+### Reading and clearing
+
+<CodeGroup>
+```python Python
+# Read the current value
+response = client.project.get(fields=["agent_custom_instructions"])
+print(response["agent_custom_instructions"])
+
+# Clear it; agent memories fall back to custom_instructions
+client.project.update(agent_custom_instructions="")
+```
+
+```javascript JavaScript
+// Read the current value
+const response = await client.getProject({
+  fields: ["agentCustomInstructions"],
+});
+console.log(response.agentCustomInstructions);
+
+// Clear it; agent memories fall back to customInstructions
+await client.updateProject({ agentCustomInstructions: "" });

+title: Dream
+description: "Dream keeps a user's memory clean over time by distilling recurring patterns, retiring outdated facts, and merging duplicates in the background."
+---
+
+# Dream
+
+As an application talks to the same user over weeks and months, their memory grows. Some of that growth is signal, meaning new facts worth keeping. A lot of it is noise: the same preference stated three different ways, an old fact that a newer one has quietly replaced, or a set of small observations that only mean something when you look at them together.
+
+**Dream** is the background layer that keeps a user's memory coherent as it grows. It continuously reviews each user's memories and does three things. It synthesizes higher-order patterns, supersedes outdated facts, and merges duplicates. The result is that what you read back stays sharp instead of drifting into a pile of overlapping, stale entries.
+
+<Info>
+  **Dream matters when…**
+  - Your users interact with your product over a long period and accumulate a lot of memories.
+  - You want retrieval to return the *current* truth about a user, not a mix of old and new contradictory facts.
+  - You want higher-level insights ("this user consistently prefers X") without writing your own summarization layer.
+</Info>
+
+## The three actions of Dream
+
+Dream is made of three independent actions. Two of them, Supersede and Merge, keep memory clean and run automatically for everyone. The third, Synthesis, produces new insight and is a toggle you turn on per project.
+
+| Action | What it does | When it runs | Availability |
+|---|---|---|---|
+| **Synthesis** | Distills a user's memories into higher-order **pattern memories** | On a schedule, in the background | Opt-in (Pro and above) |
+| **Supersede** | Marks an older fact as outdated when a newer one contradicts it | As memories are added | Always on, all plans |
+| **Merge** | Folds a duplicate into a single canonical memory | As memories are added | Always on, all plans |
+
+### Synthesis
+
+Over time a user's memories often *imply* something larger than any single entry. Ten separate notes about early-morning meetings, workout logs, and coffee orders together say "this user is an early riser." **Synthesis** finds those recurring threads and writes them back as new **pattern memories**: concise, higher-order facts that capture what the individual memories only hint at.
+
+- Pattern memories are added *alongside* your existing memories, never in place of them. The source memories stay exactly where they are.
+- Each pattern memory keeps a link back to the specific memories it was distilled from, so an insight is always traceable to its evidence.
+- Synthesis is additive and idempotent. Re-running it will not create duplicate patterns for the same underlying evidence.
+
+**Example.** These four memories accumulate for the same user over time:
+
+- *"User runs approximately 40 kilometers per week and is currently training for a marathon."*
+- *"User lifts weights at the gym three times a week, primarily focusing on legs and back."*
+- *"User tracks all workouts using a Garmin Forerunner watch."*
+- *"User's goal for 2026 is to run a sub-4-hour marathon."*
+
+Synthesis distills them into one pattern memory, kept alongside the originals:
+
+> *"User follows a structured fitness routine that includes weekly long runs (≈40 km), regular leg-and-back strength training, tracks workouts with a Garmin device, and pursues progressive marathon time goals."*
+
+Each source memory stays exactly where it was, and the new pattern links back to all of them as its evidence.
+
+<Note>
+  Synthesis only considers memories created **after** you enable it for a project. Turning it on sets a forward boundary, so historical memories aren't reprocessed in bulk on day one. Everything added from that point on is eligible.
+</Note>
+
+<Note>
+  Synthesis only looks at memories scoped to a **`user_id` alone**. Memories that also carry another entity (an `agent_id`, `run_id`, or `app_id`) are left out of a user's synthesis run. This keeps each run tied to a single user's own memories and avoids cross-referencing across agents, runs, or apps. So a memory has to be user-scoped, with no other entity attached, to be eligible for a pattern.
+</Note>
+
+### Supersede
+
+When a user tells you something that **contradicts** an earlier memory ("I moved to Berlin" after an earlier "I live in Lisbon"), Dream marks the older memory as **superseded** and links it to the newer fact that replaced it. Superseded memories are not deleted and not hidden by default. A normal `search` or `get` still returns them alongside your active memories, badged as superseded, so you keep the full history. When you want only the current truth, ask for it explicitly with `latest_only=true` (see [How reads change](#how-reads-change-with-dream) below). Supersede runs automatically as part of adding memories, on every plan.
+
+**Example.** The user has an existing memory *"User drives a 2019 Subaru Outback."* Later they mention selling it, producing a new memory *"User sold their 2019 Subaru Outback and bought a Tesla Model 3."* Dream marks the Subaru memory as superseded and links it to the newer one. A default `search` returns both: the Tesla memory as active, and the Subaru one labelled superseded. Passing `latest_only=true` returns only *"User sold their 2019 Subaru Outback and bought a Tesla Model 3."*
+
+### Merge
+
+When a new memory is effectively a **duplicate** of one you already have, Dream keeps a single canonical memory instead of two near-identical copies. When a duplicate is stored as its own memory, Dream marks it **merged** and links it to the canonical one. The merged record is hidden from reads by default (you get the one canonical memory), retained rather than deleted, and surfaced with `include_merged=true`. Merge runs automatically as memories are added, on every plan, and keeps your memory set compact without you deduplicating by hand.
+
+In practice, most exact or near-duplicate restatements of a fact you already have are recognised and deduplicated as the memory is added. No second copy is created, so you simply keep the one memory. A distinct `merged` record appears when a fuller version of an existing fact arrives and folds the barer one in.
+
+**Example.** The user has an existing memory *"User has a dog named Rex."* Later they mention *"My dog Rex is a 3-year-old golden retriever."* The richer statement is stored and Dream marks the barer *"User has a dog named Rex"* as **merged** into it. A default read returns the single canonical memory *"User's dog Rex is a 3-year-old golden retriever"*, and `include_merged=true` also returns the merged original.
+
+<Info>
+  **Nothing Dream does is destructive.** Superseded and merged memories are retained, never erased. Every change is recorded and reviewable, so you always know why a memory was retired or combined.
+</Info>
+
+## How reads change with Dream
+
+Dream doesn't change the shape of your `add`, `search`, or `get` calls, so you don't touch your application code. What it changes is *which* memories a read returns by default, and it gives you two flags to widen or narrow that set:
+
+| Read mode | Active | Superseded | Merged |
+|---|:---:|:---:|:---:|
+| **Default** (`search` / `get`) | ✓ | ✓ | ✗ |
+| **`latest_only=true`** | ✓ | — | — |
+| **`include_merged=true`** | ✓ | ✓ | ✓ |
+
+- **By default**, a read returns active plus superseded memories (superseded ones are still there, labelled as history) and hides merged duplicates. Synthesized pattern memories are returned alongside these too.
+- **`latest_only=true`** narrows the result to active memories only, meaning the current truth, with superseded and merged both excluded. Use this when you want the cleanest possible snapshot of the user right now.
+- **`include_merged=true`** returns everything, including the merged duplicates, when you need the complete picture.
+
+## Enabling Dream
+
+Supersede and Merge require no setup. They're always on for every project on every plan.
+
+Synthesis is opt-in per project:
+
+1. Open the **[Dream settings for your project](https://app.mem0.ai/dashboard/dream)** in the Mem0 dashboard.
+2. Toggle **Synthesis** on.
+
+Synthesis is a per-project setting, so you can enable it for one project and compare against another with it off. You can turn it off at any time. Doing so is fully reversible and leaves every existing memory (including already-synthesized patterns) untouched.
+
+From the [Dream page](https://app.mem0.ai/dashboard/dream) you can also review what Dream has done: recent synthesis runs, the patterns produced and their source memories, and the memories that were superseded or merged.
+
+## Plan availability
+
+| Capability | Free | Starter | Pro | Enterprise |
+|---|:---:|:---:|:---:|:---:|
+| **Supersede** (outdated facts flagged) | ✓ | ✓ | ✓ | ✓ |
+| **Merge** (duplicates folded, hidden by default) | ✓ | ✓ | ✓ | ✓ |
+| **Synthesis** (pattern memories written) | — | — | ✓ | ✓ |
+| **Dream dashboard** (runs, activity) | — | — | ✓ | ✓ |
+
+Synthesis requires a **Pro plan or higher**. Enterprise plans also get a faster, configurable schedule (see below).
+
+## How often Dream runs, and what delay to expect
+
+Different actions run on different clocks, so the delay you should expect depends on which action.
+
+### Supersede & Merge, as memories are added
+
+Supersede and Merge are part of the memory-addition pipeline. They're evaluated when a memory is added, so an outdated fact is superseded or a duplicate is merged as part of that add being processed, on the same timescale as the memory becoming searchable. There's no separate schedule to wait for.
+
+### Synthesis, on a schedule in the background
+
+Synthesis runs as a scheduled background job per user, not on every add. Two conditions gate it:
+
+- **Enough to work with:** a user must have at least **20** memories before Synthesis considers them. Below that threshold there isn't a meaningful pattern to distill yet.
+- **Cadence elapsed:** each user is re-synthesized at most once per cadence window.
+
+| Plan | Synthesis cadence (per user) |
+|---|---|
+| Pro | Every **7 days** |
+| Enterprise | **Daily** (and configurable) |
+
+Because Synthesis is processed in batches in the background, **expect new pattern memories to appear within roughly 24 hours of a scheduled run**, not instantly. In practice, the end-to-end delay from crossing a cadence window to seeing new patterns is up to about a day. This background design is deliberate: it keeps Synthesis from adding any latency to your live `add` and `search` calls.
+
+<Warning>
+  Synthesis is **not** real-time. If you enable it today, the first pattern memories for an eligible user will appear on the next scheduled run for that user (governed by the cadence above), and can take up to ~24 hours to complete once that run starts. Supersede and Merge, by contrast, keep pace with your adds.
+</Warning>
+
+## FAQ
+
+**Does Dream delete any of my memories?**
+No. Nothing Dream does is destructive. Superseded memories stay visible in default reads (labelled as history), merged duplicates are hidden by default but retained, and synthesized patterns are added alongside your existing memories, never in place of them. Every change is reviewable from the dashboard.
+
+**How do I get only the current facts, without the superseded ones?**
+Pass `latest_only=true` on your read. Superseded and merged memories are both excluded, leaving only active memories. By default (no flag) superseded memories are included so you keep the full history.
+
+**Do I need to change my code to use Dream?**
+No. Supersede and Merge are always on, and enabling Synthesis is a project setting. Your `add`, `search`, and `get` calls are unchanged. Dream shapes the memory set behind the same API.
+
+**Will Synthesis reprocess all my old memories when I turn it on?**
+No. Enabling Synthesis sets a forward boundary, so only memories created after you turn it on are eligible. This avoids a bulk reprocess of your entire history on day one.
+
+**Why don't I see pattern memories immediately after enabling Synthesis?**
+Synthesis runs on a schedule (every 7 days on Pro, daily on Enterprise) and only for users with at least 20 memories. Patterns appear on the next scheduled run for an eligible user and can take up to ~24 hours to complete once that run starts.
+
+**Which memories does Synthesis include?**
+Only memories scoped to a `user_id` on its own. If a memory also carries an `agent_id`, `run_id`, or `app_id`, it's excluded from that user's synthesis run. This keeps each run confined to a single user's memories and prevents any cross-referencing across agents, runs, or apps. Supersede and Merge are not affected by this and run across your memories as usual.
+
+**Are synthesized pattern memories traceable?**
+Yes. Every pattern memory links back to the specific source memories it was distilled from, so you can always see the evidence behind an insight from the Dream dashboard.
+
+**Can I turn Synthesis off?**
+Yes, at any time, per project. Turning it off is fully reversible and leaves all existing memories, including already-synthesized patterns, untouched.

-description: "Time-aware memory retrieval for Mem0 Platform v3 so queries like 'last week', 'upcoming', and 'right now' return the right memories."
+description: "Boost memories whose dates match the time in a search."
 badge: "v3"
 ---
 
-Some memories matter because of **when** they happened, not just because they sound similar. Temporal Reasoning lets Mem0 Platform v3 understand time-aware queries and return the most contextually appropriate results.
+Temporal Reasoning gives a ranking boost to memories whose event dates match the time in a search. Event dates are when something described in a memory happened or will happen. It runs automatically on Mem0 Platform v3.
 
-<Info>
-  **Use Temporal Reasoning when…**
-  - Users ask questions like "what happened last week?" or "what do I have coming up?"
-  - Your app stores both past events and future plans for the same person
-  - You want time-aware retrieval without building your own date-parsing layer
-</Info>
+It is not available in the OSS SDK.
 
-<Warning>
-  Temporal Reasoning is a **Mem0 Platform v3** feature. It is not available on OSS memory stores or older Platform endpoints.
-</Warning>
+Dates from new memories usually affect search within a few seconds.
 
-## Configure access
+## Time-aware searches
 
-Confirm your `MEM0_API_KEY` is set and that you are using the v3 Platform client:
+Queries can include expressions such as `yesterday`, `last week`, `tomorrow`, `currently`, and `as of March 2025`. Mem0 compares them with dates and date ranges found in stored memories.
 
-```python
-from mem0 import MemoryClient
+## Example
 
-client = MemoryClient(api_key="your-api-key")
-```
+Suppose a user has these memories:
 
-## How it works
+- "Yesterday I met Maya at the Orion conference in Paris."
+- "Last week I met Maya at the Orion conference in Tokyo."
+- "Last year I met Maya at the Orion conference in Lisbon."
 
-When a memory describes an event, a future plan, or an ongoing state, Temporal Reasoning recognizes the time context so the right results surface at search time.
-
-A query like `what did I do last week?` should return a completed past event: not an upcoming appointment and not a stable fact that hasn't changed. Temporal Reasoning handles that distinction automatically.
-
-### Memory types Temporal Reasoning handles
-
-| Type | What it represents | Example |
-| --- | --- | --- |
-| Dated occurrence | Something that happened at a known time | "I finished the Q1 review on March 10, 2025." |
-| Future plan | A future commitment or scheduled item | "I have a dentist appointment on March 18, 2025." |
-| Ongoing state | A fact that remains true over time | "I am the product lead at Acme Corp." |
-| Relationship | A durable connection between people or entities | "Priya manages Jordan." |
-| Preference | A stable preference or habit | "I prefer morning meetings." |
-
-Results come back in the normal search response shape: Temporal Reasoning affects ranking, not the response format.
-
-## Configure it
-
-Temporal Reasoning is enabled by default for all v3 searches and writes. There is no per-request toggle.
-
-Two parameters give you precise control when you need it:
-
-- `observation_date` (or `observation_datetime`, which takes priority when both are set) on `add()`: anchors an imported memory to the time it actually happened. Pair with `timezone` when resolving a date-only value.
-- `timestamp` on `add()`: a Unix epoch that sets the memory's creation time. When present it takes priority over `observation_datetime` and `observation_date` as the anchor Temporal Reasoning ranks against, so pass only the one you want to win.
-- `reference_date` on `search()`: resolves relative phrases like `last week` against a fixed point in time
+Searching for `Which city did I meet Maya in at the Orion conference last week?` gives the Tokyo memory a temporal boost and ranks it first.
 
 <CodeGroup>
 ```python Python
-from mem0 import MemoryClient
-
-client = MemoryClient(api_key="your-api-key")
-
-client.add(
-    [{"role": "user", "content": "I finished the Q1 review on March 10, 2025."}],
-    user_id="jordan",
-    observation_date="2025-03-10",
-)
-
 results = client.search(
-    "what did I do last week?",
-    filters={"user_id": "jordan"},
+    "Which city did I meet Maya in at the Orion conference last week?",
+    filters={"user_id": "maya-demo"},
+)
+```
+
+```javascript JavaScript
+const results = await client.search(
+  "Which city did I meet Maya in at the Orion conference last week?",
+  { filters: { user_id: "maya-demo" } }
+);
+```
+</CodeGroup>
+
+Search returns the usual memory results, reordered using the temporal boost.
+
+## Search from a specific time
+
+Use `reference_date` to simulate searching at a specific date and time. Mem0 treats it as the current time for that search.
+
+<CodeGroup>
+```python Python
+results = client.search(
+    "What happened last week?",
+    filters={"user_id": "user-123"},
     reference_date="2025-03-21T00:00:00Z",
 )
 ```
 
 ```javascript JavaScript
-import { MemoryClient } from "mem0ai";
-
-const client = new MemoryClient({ apiKey: "your-api-key" });
-
-await client.add(
-  [{ role: "user", content: "I finished the Q1 review on March 10, 2025." }],
-  {
-    userId: "jordan",
-    observationDate: "2025-03-10",
-  }
-);
-
-const results = await client.search("what did I do last week?", {
-  filters: { user_id: "jordan" },

+  filters: { user_id: "user-123" },
   referenceDate: "2025-03-21T00:00:00Z",
 });
 ```
 </CodeGroup>
 
-<Tip>
-  `reference_date` is especially useful in automated tests and demos because it makes relative phrases like `last week` resolve consistently every time.
-</Tip>
+## Parameters

-## Verify the feature is working
-
-- Run a temporal search with a time-aware query (e.g., "what did I do last week?") and confirm the memory that fits the time window ranks first.
-- Use `reference_date` in test queries so relative phrases resolve consistently across runs.
-- For backfilled data, pass `timestamp` on `add()` to confirm the memory reflects the right point in time.
-
-## Best practices
-
-- Use explicit dates in source conversations when events or plans matter temporally.
-- Pass `observation_date` (or `observation_datetime`) during historical imports so the ingestion time does not become the only time anchor. Do not also pass `timestamp` on those calls, since it overrides both as the ranking anchor.
-- Scope searches with `filters` so time-aware ranking operates inside the right user boundary.
-- Use `reference_date` in automated tests and reproducible demos.

+"""Resolve the project's mem0 extraction policy from ``mem0.md``.
+
+A repo's ``mem0.md`` can carry two prose sections that steer what Mem0 extracts:
+
+    ## Instructions
+    Remember architecture decisions and conventions. Ignore debug noise and secrets.
+
+    ## Agent Instructions
+    For agent-scoped memories, focus on the tools and task outcomes.
+
+``## Instructions`` maps to Mem0's ``custom_instructions`` (user/project-scoped
+extraction) and ``## Agent Instructions`` to ``agent_custom_instructions``
+(agent-scoped extraction). Both are passed verbatim on memory writes, so the
+policy lives in the repo, travels with it, and is shared by the whole team.
+
+The hook writers call :func:`load_instructions` and merge the result into their
+``/v3/memories/add`` body. Returns only the keys that are actually set, so a
+project with no policy adds nothing.

+# Kimi Code hook adapter.
+#
+# Kimi Code's hook contract is close to Claude Code's but differs in four ways
+# that the mem0 hook scripts care about. Rather than fork nine scripts, every
+# Kimi hook entry in .kimi-plugin/plugin.json routes through this shim.
+#
+#   1. cwd     Kimi runs hook commands with cwd forced to the PLUGIN root
+#              (agent-core-v2 src/app/plugin/manager.ts -> enabledHooks() sets
+#              `cwd: record.root`). The real project directory only arrives as
+#              the payload's `cwd` field. _project.sh resolves MEM0_PROJECT_ID
+#              from $PWD/`git remote`, so we chdir into the payload cwd first.
+#
+#   2. stdin   Kimi sends snake_case JSON like Claude, but:
+#                - `prompt` is a ContentPart[] array, not a string
+#                - PostToolUse sends `tool_output`, not `tool_response`
+#                - file tools use `tool_input.path`, not `tool_input.file_path`
+#                - plugin MCP tools are `mcp__plugin-mem0_mem0__*` (hyphen),
+#                  not Claude's `mcp__plugin_mem0_mem0__*`
+#                - there is NO `transcript_path` (no equivalent exists)
+#              We normalise the first four into the Claude shape.
+#
+#   3. stdout  Kimi's hook stdout parser (agent-core-v2
+#              src/agent/externalHooks/runner.ts -> HookJsonOutputSchema) only
+#              understands top-level `message`, `hookSpecificOutput.message`,
+#              `hookSpecificOutput.permissionDecision` and
+#              `hookSpecificOutput.permissionDecisionReason`.
+#              `additionalContext` and `updatedInput` are NOT recognised.
+#              Raw (non-JSON) stdout IS appended to context for UserPromptSubmit
+#              (user-prompt.ts -> userPromptHookMessage falls back to stdout), so
+#              we unwrap additionalContext into plain text.
+#
+#   4. exit    Same as Claude: 0 = allow, 2 = block (stderr is the reason),
+#              any other code / timeout = fail-open.

+description: Views or sets the project's memory-extraction policy (what Mem0 remembers vs ignores) stored in mem0.md. Use when the user says set a memory policy, custom instructions, what should mem0 remember, tell mem0 to ignore X, or asks to see/change the current instructions.
+---
+
+# Mem0 Policy
+
+The project's memory policy lives in a `## Instructions` section of `mem0.md` at
+the repo root. It is version-controlled and shared by the whole team, and it maps
+to Mem0's `custom_instructions` (what to extract / ignore). An optional
+`## Agent Instructions` section maps to `agent_custom_instructions` (guidance for
+agent-scoped memories only).
+
+The policy takes effect on the **next session** (mem0.md is re-parsed on
+SessionStart) and is applied automatically on the plugin's memory writes.
+
+## Execution
+
+### Step 1: Determine intent from the argument
+
+`/mem0:policy` is invoked as `/mem0:policy [<subcommand>] <text>`:
+
+| Argument | Action |
+|---|---|
+| _(none)_ or `show` | Show the current policy |
+| `set <text>` or free text | Set/replace the `## Instructions` (custom) policy |
+| `agent <text>` | Set/replace the `## Agent Instructions` policy |
+| `clear` | Remove both policy sections |
+
+### Step 2: Locate mem0.md
+
+`mem0.md` sits at the repo root (the current working directory). If it does not
+exist yet and the user is setting a policy, you will create it.
+
+### Step 3a: Show
+
+Run `python3 "$CLAUDE_PLUGIN_ROOT/scripts/parse_mem0_config.py" --key instructions .`
+and `--key agent_instructions .` (or read `mem0.md` directly). Print:
+
+```
+Memory policy for this project (mem0.md):
+  Instructions:       <text, or "(none)">
+  Agent Instructions: <text, or "(none)">
+```
+
+If `mem0.md` is absent, say there is no policy yet and offer to set one.
+
+### Step 3b: Set / clear
+
+Edit `mem0.md`, adding or replacing the target section. Keep the instruction a
+short prose paragraph (what to remember, what to ignore). Example:
+
+```markdown
+## Instructions
+Remember architecture decisions, API contracts, and team conventions.
+Ignore transient debugging output, stack traces, and anything resembling a secret.
+```
+
+- Preserve any other existing sections (`## Retention`, `## Categories`, etc.).
+- If the section already exists, replace its body; otherwise append the section.
+- For `clear`, delete the `## Instructions` and `## Agent Instructions` sections.
+
+### Step 4: Confirm
+
+```
+Updated memory policy in mem0.md.
+Takes effect next session. Commit mem0.md to share it with your team.
+```
+
+Remind the user that `## Agent Instructions` only affects agent-scoped memories,
+so it is a no-op unless memories are written with an `agent_id`.
