fix(memory): confine memory RPCs/MCP to the caller's root, police ingest paths, private state files, random local root - #7142
Conversation
Add the tinymemory package to the vendor directory so it can be used without fetching it at build time. Auto-committed-on: macbook Co-authored-by: Medulla <medulla@tinyhumans.ai>
Path confinement now rejects any resolved path that escapes the workspace root, closing a gap where relative segments could reach outside it. Auto-committed-on: macbook Co-authored-by: Medulla <medulla@tinyhumans.ai>
Introduce handlers for the memory schemas module so memory operations can be dispatched through the schema layer. This wires up the new handlers in the memory module to support the added functionality. Auto-committed-on: macbook Co-authored-by: Medulla <medulla@tinyhumans.ai>
Adds a handler module for memory schema operations so schema requests can be dispatched through the standard handler path. Auto-committed-on: macbook Co-authored-by: Medulla <medulla@tinyhumans.ai>
Memory file access now resolves paths against the workspace root and rejects anything that escapes it, so handlers can no longer read or write outside the intended directory. The confinement check is shared by the schema handlers that touch memory files. Auto-committed-on: macbook Co-authored-by: Medulla <medulla@tinyhumans.ai>
Adds tests covering path confinement behaviour in the memory module to guard against regressions in how memory paths are validated. Auto-committed-on: macbook Co-authored-by: Medulla <medulla@tinyhumans.ai>
Split the brain store logic into smaller helper functions to make the read and write paths easier to follow. Behaviour is unchanged. Auto-committed-on: macbook Co-authored-by: Medulla <medulla@tinyhumans.ai>
Reinstated the brain memory tests and file handling logic that had been dropped, so the memory module's behaviour is exercised again. This brings back the expected coverage and fixes the regression in file operations. Auto-committed-on: macbook Co-authored-by: Medulla <medulla@tinyhumans.ai>
The monolithic memory module was reorganised into channels, layout migration, lifecycle jobs, and sources submodules so that each concern has a clear home. No behaviour changes; the public surface is preserved through re-exports in mod.rs. Auto-committed-on: macbook Co-authored-by: Medulla <medulla@tinyhumans.ai>
Auto-committed-on: macbook Co-authored-by: Medulla <medulla@tinyhumans.ai>
The test now imports BackgroundJob from tinymemory_tools instead of the lifecycle jobs module, matching where the trait is actually defined. Auto-committed-on: macbook Co-authored-by: Medulla <medulla@tinyhumans.ai>
Moved the logic that resolves the local memory root directory into a dedicated helper so it can be reused and tested independently. No behaviour change. Auto-committed-on: macbook Co-authored-by: Medulla <medulla@tinyhumans.ai>
Introduce a memory scope abstraction so reads and writes can be restricted to a defined subset of memory. Scope resolution and its tests are added alongside the module wiring. Auto-committed-on: macbook Co-authored-by: Medulla <medulla@tinyhumans.ai>
Add coverage for local memory root resolution, exercising the path handling that determines where memory files are stored. Auto-committed-on: macbook Co-authored-by: Medulla <medulla@tinyhumans.ai>

Collapse a multi-line file write into a single call and replace single-element array comparisons with std::slice::from_ref to avoid unnecessary clones in the confinement and brain tests. Auto-committed-on: macbook Co-authored-by: Medulla <medulla@tinyhumans.ai>
The spec now describes how the ambient-config RPCs and MCP memory tools are confined to the identity in scope, including how reach is narrowed and how out-of-subtree calls are refused. It also records that a signed-out session's scope root is a random per-install id, falling back to the older hostname-derived root so existing memory is not orphaned.

Tiny Sweeper reviewTiny Sweeper completed its review; deterministic results follow. State: Reviewing pending checks Review snapshot
Completeness: Complete What changedA new `confine` module wraps every ambient memory RPC handler (`recall`, `fetch`, `learn`, `forget`, `items_list`, `explore`, `items_get`) so an unset `reach` defaults to the identity in scope's subtree (`Reach::subtree`), a wider reach is refused with `INVALID_REQUEST`, `forget`/`items_get` skip ids outside it, and `learn` lands at the layout's learnings node unless aimed outside the subtree. `memory_brain_ingest` now resolves file paths through `SecurityPolicy::validate_path` before reading. A new `files` module provides `write_private`, `create_private`, and `create_private_dir_all`, and every memory state writer (job queue, channel threads, source sync state, connection roots, connector versions, layout migration state) is switched to them. A new `local_root` module mints `user:local-<uuid>` for signed-out sessions, recording it once (write-once via hard-link, with a legacy-root fallback for installs already on layout v3 or mid-migration), and `scope::user_root` delegates to it; its per-process cache is keyed by the per-user record path. The spec document documents the confinement and the new local root. Features

Drive the confined handlers through the end-to-end suite
This changes the registered RPC path from ops::recall to confine::recall, but the available tests call the confinement functions directly rather than invoking the registered memory RPCs. The end-to-end suite therefore does not prove that these handlers are actually wired to the confined implementations; add an RPC-level test that exercises the confined memory operations, including an out-of-root request.
Additional security observation
Key the cache by the local user identity
[RULE] identity-scoped-cache
This newly activated confinement path relies on the current identity resolution, but the cache remains keyed without the local user identity. When multiple local users share the process, a cached resolution can apply one user's root to another user's RPC, causing memory reads or writes to be scoped to the wrong user. Include the local user identity in the cache key or avoid sharing the resolved scope across users.

Exercise local-session root resolution end to end
The new handler now depends on confine::fetch, whose permitted reach is derived from the current session identity. The available unit coverage checks configuration roots and team-member scope, but does not drive a local-session request through the RPC handler, so a regression in local-session root resolution could still expose or hide the wrong memory. Add an end-to-end case that establishes a local session, stores data in separate roots, and verifies the handler only returns the session's root.

Drive confined memory RPCs in end-to-end tests
The handlers now use a security boundary for listing, exploration, recall, fetch, learning, forgetting, and item access, but the end-to-end suite does not exercise these confined RPCs. Without requests using both an allowed root and a sibling or parent root, a regression could silently restore cross-root reads or deletes.

Cover local-session root resolution end to end
These handlers resolve the acting identity from the local session before applying confinement, but the end-to-end suite has no coverage for the local-session path. A test should establish a session with a distinct root, invoke the RPCs, and verify that unset and explicit reaches stay within that root rather than falling back to the config root.

Drive the confined memory RPCs end to end
This revision changes the live RPC path to use the confinement layer, but the end-to-end suite still does not exercise these confined memory controllers. Without an end-to-end assertion, a registry or transport wiring regression could silently expose the old unconfined path again. Add coverage that invokes the registered memory RPCs and verifies requests are confined.

Cover local-session root resolution end to end
The new handler dispatch depends on the caller's local-session root being resolved correctly by confine, but the existing end-to-end coverage does not exercise that path. Add a test using distinct local roots and verify that items_get cannot read an item outside the active session's root.

Local-session root resolution has no end-to-end coverage
Still only exercised by unit tests in local_root_tests.rs and scope_tests.rs; no test under tests/ boots the core as a signed-out local session and observes that memory lands under the recorded install-id root. The change rewires user_root (scope.rs), so a regression in the workspace/config-path layout assumptions would only fail at unit level, not in the suite that mimics real installs. Unchanged since last cycle, so it keeps its level.

Local-session root resolution has no end-to-end coverage
A signed-out session's scope root is now user:local-<install id> read or minted from <workspace>/memory/local_root., with a legacy fallback — a persisted format and a behaviour every local launch depends on: if resolution ever fails, memory silently stays off. No end-to-end test drives a signed-out boot and checks that the record file is created, stable across relaunch, or that memory keeps working under the recorded root. A test would have to run the desktop app signed out, relaunch it, and assert the same root (e.g. via a workspace file or a memory RPC) both times. Still uncovered; kept at medium.

Summary
openhuman.memory_*RPCs (recall, fetch, learn, forget, items_list, explore, items_get) and the MCP memory tools that dispatch through them are now confined to the caller's identity root. This is the sameReach::subtree(root)confinement the agentmemorytool applies. Audit refs: 01-scopes F5, 02-security S6.memory_brain_ingestwithpathnow goes throughSecurityPolicy::validate_path, the same check the file tools use. This adds theis_always_forbiddenfloor (~/.ssh,~/.aws,/etc, …), checked on the resolved path so symlinks are covered, plus..traversal and null-byte rejection. Audit ref: S10.<workspace>/memoryis 0700. Existing wider files and directories are narrowed on their next write. Audit ref: S10.user:local-<random install id>, recorded once in the workspace. It is no longer a hash of the hostname. An existing install keeps its current root through a one-time recorded mapping.

If the layout migration has started (its state file exists) or finished (layout = "v3"), it records the old hostname-derived root instead, because memory already lives there. The record is written once with a hard-link-or-read, so a race between processes keeps the first record. If the record cannot be read or written, memory stays off rather than writing under a root the next launch would not find.Submission Checklist
