When a turn record lacks a `data` field, the session now returns an empty map instead of failing with a deserialization error. This prevents crashes when processing incomplete or legacy turn entries. Auto-committed-on: dragonfly Co-authored-by: Medulla <medulla@tinyhumans.ai>
…er implementation The MemoryLoader trait and its DefaultMemoryLoader implementation have been removed as they are no longer used. The memory context loading functionality has been superseded by the compressed memory tree and on-demand memory search tool, making this abstraction unnecessary. Auto-committed-on: dragonfly Co-authored-by: Medulla <medulla@tinyhumans.ai>
…tation Introduce a `MemoryLoader` trait with a `DefaultMemoryLoader` that consolidates user working memory, prior conversations, and cross-chat context into a single prompt block. This replaces the previous ad-hoc injection of semantic memory context, which duplicated content already available through the compressed memory tree and the on-demand memory search tool, and could echo the user's own message back at them. The new loader respects a configurable character budget, per-profile opt-out of agent conversation recall, and includes date stamps on facts to prevent stale information from being presented as current.

…trait The `DefaultMemoryLoader` struct and its `MemoryLoader` trait implementation have been removed as they are no longer used. The memory loading functionality has been superseded by the agent's memory tree and on-demand memory search tool, making this code dead. Auto-committed-on: dragonfly Co-authored-by: Medulla <medulla@tinyhumans.ai>
…n types The memory loader field and its associated setter method have been removed from the agent builder, factory, and session types. This change eliminates the unused memory loader infrastructure that was no longer needed after the memory loading logic was moved elsewhere. Auto-committed-on: dragonfly Co-authored-by: Medulla <medulla@tinyhumans.ai>
Removed the `DefaultMemoryLoader` import from two builder files and its corresponding field initialization in the setter, as this type is no longer used in the session builder. Auto-committed-on: dragonfly Co-authored-by: Medulla <medulla@tinyhumans.ai>
Removed several unused imports that were no longer referenced in the memory loader module, including PathBuf, async_trait, and various constants and modules related to conversation memory and agent harness context. This cleanup reduces compilation overhead and makes the dependency graph clearer. Auto-committed-on: dragonfly Co-authored-by: Medulla <medulla@tinyhumans.ai>
Removed an unused import of `provenance_tag` from the memory loader module to eliminate a compiler warning and keep the codebase clean. Auto-committed-on: dragonfly Co-authored-by: Medulla <medulla@tinyhumans.ai>
Introduces a new types module to define the core data structures used during transcript ingestion, establishing a clear contract for how transcript data is represented and processed within the learning pipeline. Auto-committed-on: dragonfly Co-authored-by: Medulla <medulla@tinyhumans.ai>
When a transcript file is empty, the ingestion process now returns an empty result instead of failing with an error. This allows the system to continue processing other files without interruption. Auto-committed-on: dragonfly Co-authored-by: Medulla <medulla@tinyhumans.ai>
When a turn record is absent from the session state, the system now returns an appropriate error instead of panicking or producing undefined behavior. This ensures robustness when processing incomplete or corrupted session data. Auto-committed-on: dragonfly Co-authored-by: Medulla <medulla@tinyhumans.ai>
Prevent a panic when the dispatch processor encounters an empty queue by adding a guard clause that returns early instead of attempting to process a nonexistent item. This ensures graceful handling of edge cases where the queue is cleared between checks. Auto-committed-on: dragonfly Co-authored-by: Medulla <medulla@tinyhumans.ai>
Removed several type definitions that were no longer referenced anywhere in the codebase, including `SessionState`, `SessionConfig`, and `SessionError`. This cleanup reduces unnecessary code and improves maintainability by eliminating dead code that could cause confusion during development. Auto-committed-on: dragonfly Co-authored-by: Medulla <medulla@tinyhumans.ai>
When a turn contains no content, the session now returns an empty response instead of failing with an error. This ensures that the system can handle edge cases where a turn is created without any input, improving robustness in automated workflows. Auto-committed-on: dragonfly Co-authored-by: Medulla <medulla@tinyhumans.ai>
When resuming a session, the runtime state may not yet be available, causing an unwrap to panic. This change replaces the unwrap with a proper check that returns an error instead, allowing the session to handle the missing state gracefully rather than crashing. Auto-committed-on: dragonfly Co-authored-by: Medulla <medulla@tinyhumans.ai>
The call to `take_last_turn_citations` was missing an `.await`, which meant the citations were never actually retrieved from the agent. Adding the await ensures the function completes and returns the correct citation data for the chat task result. Auto-committed-on: dragonfly Co-authored-by: Medulla <medulla@tinyhumans.ai>
The change introduces a `pending_citations` field initialized to `None` in the session builder's default state, enabling the session to track citations that have not yet been finalized for the current turn. Auto-committed-on: dragonfly Co-authored-by: Medulla <medulla@tinyhumans.ai>
The removed tests covered cross-chat context loading, date-stamping of working memory and prior conversations, and the agent conversations toggle. These features have been removed from the memory loader, so the corresponding tests are no longer needed. Auto-committed-on: dragonfly Co-authored-by: Medulla <medulla@tinyhumans.ai>
…rameter Removed the `FixedMemoryLoader` test struct and its `MemoryLoader` implementation, as well as the `memory_loader` parameter from all test helper functions and their call sites. The memory loader was no longer being exercised in any meaningful way after the agent's memory loading behaviour was changed, so keeping it only added noise to the test setup. Auto-committed-on: dragonfly Co-authored-by: Medulla <medulla@tinyhumans.ai>
The test module for `collect_recall_citations` was missing the `async_trait` import, causing compilation errors when using the `#[async_trait]` attribute on mock implementations. This change adds the necessary import to resolve the build failure. Auto-committed-on: dragonfly Co-authored-by: Medulla <medulla@tinyhumans.ai>
Remove the test file `tests/agent_memory_loader_public.rs` which tested the old `[Memory context]` recall block that has been removed from the loader. The tests are no longer relevant because the loader no longer emits the primary memory recall block, making these test cases obsolete. Auto-committed-on: dragonfly Co-authored-by: Medulla <medulla@tinyhumans.ai>
… e2e tests Removes the NullMemoryLoader, EmptyMemoryLoader, and StaticMemoryLoader structs along with their MemoryLoader trait implementations, as well as all calls to `.memory_loader()` in the test builders. These were no longer needed after the memory loader integration was refactored, and keeping them would cause compilation warnings or errors. Auto-committed-on: dragonfly Co-authored-by: Medulla <medulla@tinyhumans.ai>
The NullMemoryLoader implementation was removed from the streaming_support test module because it was no longer referenced by any test code, keeping the test file clean and avoiding dead code. Auto-committed-on: dragonfly Co-authored-by: Medulla <medulla@tinyhumans.ai>
Add the missing `.await` call to `take_last_citations()` in the agent session turn test, and remove the `DefaultMemoryLoader` context loading assertions from the inference agent test since they duplicate coverage already provided by the `collect_recall_citations` assertions that remain.

The mock-llm now seeds its failure and latency decisions from a per-request hash and a per-content retry counter, so concurrent turns no longer perturb one another and retries still draw fresh values. The driver records an epoch timestamp alongside the relative turn time, and the analyzer uses that epoch to filter turns that fall within the measurement window, preventing out-of-range data from skewing throughput results. The analyzer also gracefully skips unparsable JSON lines instead of crashing. Auto-committed-on: dragonfly

…nt test The citation replacement test now explicitly checks that the first recall future is cancelled when a second turn replaces it. A `RecallCancellationGuard` was added to `StaticMemory` to signal cancellation on drop, and the test waits for the cancellation flag before proceeding. This makes the test more robust by verifying the expected behaviour rather than relying on timing. Auto-committed-on: dragonfly

Summary
load_context()— the per-turn[User working memory]/[Prior conversations]/[Cross-chat context]block. It cost two full scans of theglobalmemory namespace on every turn to contribute at most nine lines to the prompt. TheMemoryLoadertrait andDefaultMemoryLoadergo with it (the trait had exactly one method).globalintoconversation_raw; user messages and assistant summaries now use unique keys so default recall does not scan them and concurrent sessions do not overwrite one shared reply.memory_recalland the other memory tools are untouched — the model fetches memory on demand instead of every turn paying for a broad guess.Problem
Under sustained load the core degraded badly: per-turn latency climbed linearly, throughput fell to a third of its starting rate, and RSS grew without plateauing.
It was not a leak and not a missing index — both were ruled out by measurement. A fresh core process pointed at an already-populated workspace started at 532 ms/turn instead of 111 ms, so the cost was inherited from stored data, not retained in the process. The indexes exist and are used; they cannot help, because the query has no selective predicate — it wants every row in the namespace.
What the turn actually did, measured at 4.26 embedding calls per turn (identical across three independent runs — each recall embeds its query, so the count is a direct proxy):
globalglobalconversation_memoryuser_pref_situationalThree full-namespace SQL recalls plus a vector query, all blocking, all before the LLM call — funding at most nine lines and ~2000 characters of prompt. At 8,600 turns the store held 9,660 documents and 10,127 chunks, all in
global, and each recall materialized ~40 MiB of embeddings. Over 20 queries against a real corpus, 99.7% of chunks scored fell below the relevance floor.The working-memory arm was the clearest defect. It built the query string
"working.user {message}"— a text hack meant to bias ranking — scanned all ofglobal, took the top 5, and then filteredkey.starts_with("working.user."). It scanned the entire namespace to find entries identified by a known key prefix. In the benchmark corpus: 2,025 documents scanned, zero eligible. Worse, it degrades silently — as ordinary chat fillsglobal, the chance aworking.user.*entry survives into the global top-5 falls toward zero, so the feature stops working long before anyone profiles it.And
globalgrew without bound because every autosaved user message was stored with an empty namespace, whichsanitize_namespacemaps toglobal— the same namespace the two hot recalls scanned.Solution
Reduce what is scanned, rather than optimising the scan. That ordering was not a guess: two optimizations aimed at the scan itself were implemented, measured, and reverted (decode-outside-the-lock, and a read-only connection pool — both landed within ±3%, i.e. noise, across four A/B pairs at two corpus sizes; see
scripts/bench/FINDINGS.md). Little's law plus 295 ms of CPU per turn at 49% core utilisation showed there was no lock queue to remove — the work itself was the cost.load_context()removed.MemoryLoader,DefaultMemoryLoader, theAgentfield, the builder setter, the factory wiring, and every test stub across five files.MemoryCitation,collect_recall_citationsandCROSS_CHAT_HEADERare kept — they have other consumers.CONVERSATION_RAW_NAMESPACE = "conversation_raw", applied to both writers (the agent turn and the channels dispatcher). Deliberately distinct fromconversation_memory, which holds derived durable facts rather than raw turns.take_last_turn_citations()becameasyncand joins whatever is in flight. The contract is unchanged — callers still get the citations for the turn they just ran — but the scan now overlaps the inference round-trip instead of preceding it.Results
Both arms on fresh workspaces, 4 minutes, concurrency 8 — the growth test:
Namespace change confirmed in the resulting stores: before wrote
global=8202; after wroteconversation_raw=17552, global=1.What is NOT fixed, stated plainly
Latency still drifts after this change (86 → 162 ms). Running the same build with memory writes also disabled isolates the remainder completely:
Flat, throughput held 99%. So every remaining drift is in the memory write path — upsert, embedding, chunk insert against a growing store — and none is left on the read side. That is a separate, smaller follow-up; the candidate flagged during investigation is the conversation-store index, which folds
threads.jsonlfrom scratch on nearly every operation.Reviewer questions I could not answer myself
working.user.*keys? I found no in-repo writer — only the query, test fixtures, and a doc comment describing them as "sync-derived profile facts". If the backend sync does populate them, this PR removes a feature that was already returning nothing in the corpora I measured; if it does not, the block was permanently empty. Someone who owns the sync path should confirm.memory_recall, but it must choose to. If any of those blocks is considered load-bearing, the alternative is to scope it to its own namespace rather than delete it — more work, same performance benefit.assistant_resp:<uuid>keys inconversation_raw, matching the user-message isolation without changing theDailycategory.Submission Checklist
