feat(memory): org:<uid> root with no user: segment; dual read of the legacy path

[senamakel]

What

Puts memory on the decided canonical root, org:<uid>, with no user:<uid> segment in any scope path (memory audit 01, F10). The hosted path also changes from org:<uid>/user:<uid>/ws:main/… to org:<uid>/ws:main/…. It bumps vendor/tinymemory to tinyhumansai/tinymemory#244 and wires the host side.

• memory::scope::user_root
  • Returns org:<id>, or org:local-<digest> when signed out.
  • The signed-out id source is unchanged; only the type prefix changed. The memory-confinement branch's install id has not landed yet; when it does, it slots into user_root_for.
  • New actor_of_root maps org:<id> to user:<id>. That is the actor, and also the retired root.
• memory::engine::rooted
  • TinyHumans wire: tenant_root = true, so no root segment is sent and memory-api pins org:<uid>.
  • Direct CortexDB: scope_root = org:<id>, registered as owned by the actor user:<id>. The actor (X-Cortex-Actor / token sub) stays user:<uid>.
  • Both wires: retired_scope_root = user:<id> while [memory] legacy_user_segment_read is on.
• New [memory] legacy_user_segment_read (default true; written to the config only when off).
  • Reads cover the old user:<id> path as well as the new one, merged and deduplicated by memory id.
  • Forgets and erasures hit both paths.
  • Writes go only to org:<id>.
  • The flag is part of the engine cache key, so flipping it rebinds.
• Layout migration claim. The legacy-tree claim is keyed on the account actor (user:<id>), so a claim marker written before this change still belongs to the same account.
• Docs. docs/specs/memory-v2.md, gitbooks/features/privacy-and-security.md and the module docs now show org:<id>/….

Tests

• memory/scope_tests.rs: the root is org:, with no user: in it, and actor_of_root works.
• memory/engine_tests.rs:
  • the direct root plus its actor owner;
  • the hosted wire sends no root;
  • the legacy read names the user: segment on both wires;
  • the flag's default and how it serializes.
• memory/layout_migration/app_host_tests.rs: the claim owner stays user:<id>. This test fails without the claim fix.
• Dual-read merge, forget on both paths and erasure on both paths are tested in tinymemory#244, against its CortexDB doubles.
• pnpm rust:layout passes. cargo check and the targeted memory tests ran with --jobs 4.

Depends on

tinyhumansai/tinymemory#244 must merge first. The gitlink points at its branch head; re-point it at the merge commit before merging this.

Rollout order

1. Ship the client with dual read: this PR plus tinymemory#244, legacy_user_segment_read = true by default.
2. Run cortexdb-saas reroot-user-segment (tinyhumansai/cortexdb-saas#23): --dry-run first, then for real.
3. Verify: every tenant reports kept_old: null, nothing remains under any org:<uid>/user:<uid>, and the backend memory e2e passes (tinyhumansai/backend#1411 adds the org: cross-tenant probes).
4. Turn off the legacy read: set legacy_user_segment_read = false, and drop the default in a later release.

Not in this PR

• A direct (self-hosted) CortexDB has no server-side move. Its user:<id> data stays readable through the flag until the host's v3 layout migration or the operator moves it.

Summary by CodeRabbit

• New Features

  • Memory is now organized under each account’s org: root. During migration, reads and forget operations can also include the previous user: root, while new writes go to the org: root.
  • Local identities now use org:local- memory roots.

• Bug Fixes

  • Erasing memory now covers the current org: tree and, while legacy reads are enabled, the previous user: tree.

tests

• Conclusion: Success
• Scope reviewed: all assigned evidence
• Lane summary: This revision re-roots layout v3 at `org:<id>` with the old `user:<id>` root kept as a retired read-only segment behind `legacy_user_segment_read`. The new pure functions (`actor_of_root`, `org_of_recorded`) and the config default/serialisation are covered by new tests in scope_tests.rs and engine_tests.rs that would fail on regression, and the doc-only edits need nothing. One gap remains: the claim that reads and forgets actually cover the retired root is pinned only at the settings-assembly level; the consuming engine code is in the vendored tinymemory dependency, which is not checked out, so the merge behaviour itself could not be verified here. _Code retrieval was unavailable (model: ladder embeddings returned 400 Bad Request: {"error":{"message":"unknown ladder vectors; known ladders are flash (also chat-v1, flash-v1), instant (also no-think, instant-v1), reasoning (also deepseek), max-reasoning (also max-reasoning-v1), deepseek-flash (also reasoning-v1, agentic-v1), deep (also luna), scribe, uncensored, vectors-oai3 (also embeddings-oai3-v1), vision (also vision-v1, multimodal-v1), image (also images-v1, image-v1), vi), so this review saw the diff alone._ _Memory was unavailable (model: cortex: v1/recall: error sending request for url (http://cortexdb:3141/v1/recall\)\), so this review ran without it._

description

• Conclusion: Success
• Scope reviewed: all assigned evidence
• Lane summary: This increment renames the scope-root helper docs and mappings to `org:<id>`, adds `actor_of_root` and the recorded-legacy-root translation, and covers them with focused tests. The logic is consistent with the rest of the PR's description, and the tests match the behavior. The change looks sound; nothing needed flagging. _Code retrieval was unavailable (model: ladder embeddings returned 400 Bad Request: {"error":{"message":"unknown ladder vectors; known ladders are flash (also chat-v1, flash-v1), instant (also no-think, instant-v1), reasoning (also deepseek), max-reasoning (also max-reasoning-v1), deepseek-flash (also reasoning-v1, agentic-v1), deep (also luna), scribe, uncensored, vectors-oai3 (also embeddings-oai3-v1), vision (also vision-v1, multimodal-v1), image (also images-v1, image-v1), vi), so this review saw the diff alone._ _Memory was unavailable (model: cortex: v1/recall: error sending request for url (http://cortexdb:3141/v1/recall\)\), so this review ran without it._

e2e

• Conclusion: Neutral
• Scope reviewed: all assigned evidence
• Lane summary: The change re-roots layout v3 memory from `user:<id>` to `org:<id>`, adds a tenant-root wire mode, and adds the `legacy_user_segment_read` dual-read flag. The existing Rust E2E suite (tests/memory_v2_e2e.rs, run by the pending `Rust E2E (mock backend)` job) exercises memory RPCs against the running core, but nothing in any e2e harness drives the new retired-`user:<id>` read/forget path or the tenant-root wire setting, so those new behaviours rest only on unit tests of `rooted`/config serialization.

📝 Walkthrough

Walkthrough

Person memory roots now use the org: namespace, with user: identifying the actor. A default-enabled setting supports reading and forgetting from the earlier user: scope while writes use org:. Engine binding, migration claims, and memory erasure descriptions reflect the updated roots.

Changes

Memory scope migration

Layer / File(s)	Summary
Root and migration-read settings crates/openhuman-core/src/config/schema/memory.rs, crates/openhuman-core/src/memory/scope.rs, crates/openhuman-core/src/memory/scope_tests.rs	Account and local-session roots use org:. actor_of_root maps org: roots to user: actors. legacy_user_segment_read defaults to true and is omitted from serialization when true.
Engine root and legacy-scope binding crates/openhuman-core/src/memory/engine.rs, crates/openhuman-core/src/memory/engine_tests.rs, crates/openhuman-core/src/memory/import_organize_tests.rs, vendor/tinymemory	Engine settings distinguish tenant-root mode from direct CortexDB roots and can include the earlier user: scope. Cache fingerprints include root, tenant mode, and retired-scope state. Tests use org: roots. The tinymemory submodule reference changed.
Migration claims and erasure documentation crates/openhuman-core/src/memory/layout_migration/*, crates/openhuman-core/src/memory/ops.rs, docs/specs/memory-v2.md, gitbooks/features/privacy-and-security.md	Migration claims use the actor derived from the signed-in root. Migration and erasure descriptions identify the org: destination and the earlier user: scope where applicable.

Merge Risk: 🔵 Low · up to 3f24e

The dependency pointer must be updated to the merged upstream commit before this PR merges. Otherwise the change is low risk.

Security Architecture Review

Security architecture risk: 🟡 Moderate · up to 3f24e

The change affects account isolation and permanent deletion. Compatibility is enabled by default, but disabling it before migration is complete may leave older direct-storage memory outside deletion coverage. End-to-end isolation and erasure remain partly unverified.

Retained concerns

• Medium · security · inferred: Direct account-wide deletion is coupled to a read-compatibility setting. If legacy_user_segment_read is disabled while retired user-root data remains, the new binding omits that root and erase_all does not independently target it. Before this PR, the same root was the primary deletion target. This can strand older account memory outside the configured deletion scope. Compatibility defaults to on, and disabling it is documented as requiring verified migration; these mitigate the risk but are not an enforced empty-root precondition in the binding. Actual remote deletion behavior remains unverified because the pinned dependency is unavailable. This concern does not assert that hosted whole-tenant deletion misses retired data.

Security review details

Security Blast Radius

• inferred — The configured migration exposure is one identity's canonical org root and corresponding retired user root. Direct-storage credentials may have broader authority, and the pre-v3 shared tree is explicitly treated as shared operator-controlled data. The evidence does not establish a new unauthenticated or cross-account access path.

Security Findings and Attack Paths

• inferred — The identified security outcome is conditional residual data, not verified privilege escalation: an account with retired direct-storage memory disables compatibility, then requests account-wide deletion through an engine binding that no longer names the retired root. Default-on compatibility and the documented verified-migration prerequisite reduce reachability. Hosted whole-tenant deletion is documented separately and must not be assumed to share this failure mode.

Trust Boundaries and Controls

• observed — The ordinary root is derived from the account's configuration path rather than memory request data. The org-root/user-actor split preserves the actor used for direct ownership settings and legacy claims. Hosted binding delegates root authority to the tenant-pinning contract; actual backend enforcement was not verified.

Resilience and Maintainability Implications

• observed — Migration ownership controls retain an atomic, non-replacing claim marker and reject claims held by another account. The existing service excludes simultaneous runs per workspace within the process, releases its run slot on termination, and switches by freshly loading the migrated account's own configuration. These controls reduce ownership drift during interruption and account switching.

Hardening Proposals

• proposed — Keep deletion coverage independent of read compatibility until retired-root removal is verified, or require an explicit verified-empty transition before retiring that deletion target. Validate the exact pinned client with dual-root authorization and deletion scenarios covering partial failure, interruption, repetition, concurrent writes, and compatibility toggling.
