When the remote adapter receives an empty or null graph response, the cognee_graph module now returns an empty result instead of failing with a deserialization error. This change ensures graceful degradation when the remote source has no graph data to provide. Auto-committed-on: dragonfly Co-authored-by: Medulla <medulla@tinyhumans.ai>
Introduces a new remote adapter for the mem0 graph, enabling graph-based memory operations over a remote connection. This change extends the adapter layer to support distributed memory graph functionality. Auto-committed-on: dragonfly Co-authored-by: Medulla <medulla@tinyhumans.ai>
The graph provider module was not being tracked in the remote adapter, causing build failures when the file was expected to exist. This change adds the missing file to ensure the module is properly included in the crate. Auto-committed-on: dragonfly Co-authored-by: Medulla <medulla@tinyhumans.ai>
When the remote adapter's graph provider is not set, the system now returns an appropriate error instead of panicking. This change improves robustness by ensuring that uninitialized or misconfigured remote adapters fail gracefully with a clear error message. Auto-committed-on: dragonfly Co-authored-by: Medulla <medulla@tinyhumans.ai>
Removed an unused import of `std::sync::Arc` from the remote adapter's lib.rs to clean up the code and eliminate a compiler warning about unused imports. Auto-committed-on: dragonfly Co-authored-by: Medulla <medulla@tinyhumans.ai>
The remote adapter now properly handles connection timeouts when establishing the initial connection to the remote service. Previously, a timeout would cause an unhandled error that left the adapter in an inconsistent state, preventing subsequent retry attempts. This change ensures the adapter returns a clear timeout error and allows the caller to retry the connection. Auto-committed-on: dragonfly Co-authored-by: Medulla <medulla@tinyhumans.ai>

Introduce the basic structure for the tinymemory-testing-ui crate, including a Cargo manifest, a README, and a web entry point. This establishes the foundation for building and documenting the testing interface. Auto-committed-on: dragonfly Co-authored-by: Medulla <medulla@tinyhumans.ai>
Adds the initial Cargo.toml manifest for the tinymemory-testing-ui crate, establishing its dependencies and metadata to support the new testing user interface. Auto-committed-on: dragonfly Co-authored-by: Medulla <medulla@tinyhumans.ai>
The testing UI was failing to release allocated memory blocks when the application closed, causing a memory leak. This change adds the necessary cleanup logic to free all tracked allocations before exit, ensuring the UI accurately reflects memory usage without retaining stale references. Auto-committed-on: dragonfly Co-authored-by: Medulla <medulla@tinyhumans.ai>
The `crates/tinymemory-testing-ui` directory is now a workspace member so it can be built explicitly with `-p tinymemory-testing-ui`, but it is deliberately excluded from `default-members` because it is a manual testing harness that should not be part of the normal build or release surface. Auto-committed-on: dragonfly Co-authored-by: Medulla <medulla@tinyhumans.ai>
The Cargo.lock file was updated to include the new `http-range-header` crate and the `tinymemory-testing-ui` package, along with additional dependencies for the `tower-http` crate. These changes support the addition of a new testing UI component and expanded HTTP functionality. Auto-committed-on: dragonfly Co-authored-by: Medulla <medulla@tinyhumans.ai>

Inline comments:
In `@adapters/remote/src/cognee_graph.rs`:
- Around line 37-40: Preserve the selected Cognee authentication mode across the
complete graph path: in adapters/remote/src/cognee_graph.rs:37-40, add a
Cloud/API-key graph constructor or reuse the configured memory client
authentication; in adapters/remote/src/lib.rs:55-64, expose a provider
constructor that passes the same mode to memory and graph calls; in
crates/tinymemory-testing-ui/src/main.rs:135-149, add self-hosted versus Cloud
selection and invoke the matching constructors; in
crates/tinymemory-testing-ui/web/index.html:370-383, either document that
selection or remove the unsupported Cloud claim.
In `@crates/tinymemory-testing-ui/README.md`:
- Around line 43-45: Update the credential-retention statement near the provider
connection description to accurately acknowledge that API keys are persisted in
browser localStorage and may remain after the server process exits, or remove
the localStorage persistence implemented in the UI’s relevant
credential-handling logic; keep the documentation and implementation consistent.
In `@crates/tinymemory-testing-ui/src/main.rs`:
- Around line 118-128: Update the “mem0” request handling to use the hosted Mem0
constructor for the default https://api.mem0.ai deployment, selecting
Mem0Memory::cloud or Mem0Memory::api so API keys use the required Authorization:
Token scheme; retain the existing self-hosted Mem0Memory::new path for
non-hosted endpoints.
- Around line 403-406: Remove CorsLayer::permissive() from the Router
construction so the stateful /api endpoints remain same-origin and are not
broadly readable or writable cross-origin; keep the existing nesting, fallback
service, and routing behavior unchanged.
In `@crates/tinymemory-testing-ui/web/index.html`:
- Around line 301-305: Update the graph-hint text in the op-graph section to
mention both Graph-capable engines: describe Cognee as providing dataset graph
relations and Mem0 as providing heuristic relations.
- Around line 187-212: Update the form labels in the store operation and all
repeated form fields so each label’s for attribute exactly matches its
associated input, textarea, or select id, including store-namespace, store-key,
store-content, store-category, store-taint, and store-session.
- Around line 175-185: Update the operation tabs in the tabs container and their
handlers around the tab click logic to use keyboard-operable controls,
preferably replacing the div elements with buttons while preserving their
data-op values and active-state behavior. Ensure every operation tab, including
non-default tabs, can receive focus and be activated via keyboard without
changing existing click functionality.

Introduce a new `api` constructor on `CogneeGraph` that authenticates with an `X-Api-Key` header, and expose it through a `cognee_api_graph_provider` function in the remote adapter. Extend the testing UI's connect endpoint with a `deployment` field so callers can explicitly select cloud mode, which requires a non-empty API key for both Cognee and Mem0 backends. Also remove the permissive CORS layer from the testing UI, as it is no longer needed for the intended development workflow. Auto-committed-on: dragonfly
Add a deployment selector to the memory engine configuration, allowing users to choose between self-hosted and cloud deployments. Improve form accessibility by adding proper `for` attributes to all labels and converting tab elements from divs to buttons for better keyboard navigation. Update the graph operation hint to clarify which engines provide graph relations. Auto-committed-on: dragonfly
Add a deployment selector for mem0 and cognee engines, allowing users to choose between cloud and self-hosted modes. This change updates the UI to show different default endpoints, API key requirements, and connection keys based on the selected deployment mode, making it clearer which configuration is needed for each engine variant. Auto-committed-on: dragonfly
… storage Rewrite the README to explain that Mem0 and Cognee now have explicit Cloud/self-hosted choices with correct authentication, update the credential storage section to note that the browser saves API keys in localStorage, and replace the old caveat on hosted API defaults with a clearer explanation of which engines support hosted versus self-hosted deployments. Auto-committed-on: dragonfly
Add a new test that verifies the CogneeGraph client correctly handles both cloud API keys and self-hosted bearer tokens, mirroring the existing authentication test pattern for the CogneeMemory client. Auto-committed-on: dragonfly
Replace the boolean comparison for deployment type with an explicit match that validates the deployment field, returning a clear error for unknown values. This change also adds a `self_hosted` option for Mem0 and treats `None` as self-hosted for Cognee, making the configuration more robust and user-friendly. Additionally, the response label in the HTML is updated from an inline style to a CSS class for consistency. Auto-committed-on: dragonfly
Reformatted the two `assert!` macro calls in the cloud API keys and self-hosted bearer tokens test to use a consistent indentation style, placing the opening parenthesis on the same line as the macro and aligning the closing parenthesis with the opening expression. This change is purely cosmetic and does not alter any test behaviour. Auto-committed-on: dragonfly
The `HttpClient::json` calls in `CogneeGraph` now pass `Attempts::RetryTransient` to automatically retry requests that fail due to transient network or server errors. This improves resilience against temporary outages without changing the public API or behaviour for permanent failures. Auto-committed-on: dragonfly

Summary
crates/tinymemory-testing-ui, a manual HTTP + web-UI harness for exercising TinyMemory engines by hand: pick an engine (local in-process TinyCortex, or Supermemory/Mem0/Cognee over HTTP), connect it, and call store/get/forget/list/namespaces/recall/export/graph-relations through a small browser UI. Not a host — it skips every policy layer (tier enforcement, taint stamping, redaction, egress checks) a real host owns, by design. Deliberately left out ofdefault-membersso the four contract commands never touch it (build/run explicitly with-p tinymemory-testing-ui).MemoryGraphsupport toadapters/remote:CogneeGraph— genuine, backed by Cognee's ownGET /api/v1/datasets/{id}/graph. Onlyrelationshas a real Cognee counterpart;kv_*/put_relationreturnMemoryError::Othersince Cognee has no writable KV store and its graph is derived by thecognifypipeline, not directly editable.Mem0Graph— a documented, client-side heuristic (co-occurrence of capitalized-word groups per sentence), not Mem0's native Graph Memory. That feature was removed from the self-hosted OSS package's 2.x line entirely (moved to the hosted platform product) — verified directly by downgrading tomem0ai==1.0.11+ standing up Neo4j in a scratch environment, which worked but was judged too risky to ship as a two-major-version pin change in a shared test harness.Mem0Graphgives real (not fabricated) graph output without that downgrade; every edge carries its source sentence inattrsso it can be judged on its own.GraphMemoryProvider— a small generic wrapper composing anyMemoryTraitProvider(Core/Recall/Portability) with anArc<dyn MemoryGraph>, socapabilities()andas_graph()stay honest without duplicating the mandatory-family delegation per engine.Public API / behavior changes
