Method accesses non-existent fields on wrong struct
High Severity
The get_item_count method accesses manager.learned_patterns and manager.checkpoints on a SessionManager, but these fields don't exist on that struct. The learned_patterns field belongs to LearningRepository, and there is no checkpoints field anywhere (the correct field is checkpoint_data on SessionState). The method reads from self.session_manager when it should likely read from self.learning_repository for patterns.

Tree node count not decremented during pruning
Medium Severity
The prune_branch_recursive method removes nodes from tree.nodes but never decrements tree.tree_metrics.total_nodes. When nodes are added, total_nodes is incremented, but pruning only updates paths_pruned. This causes total_nodes to overcount after any pruning, leading to incorrect results in generate_exploration_summary (reports wrong node count) and calculate_exploration_completeness (calculates inflated completeness ratio using the stale count).

Pull request overview
This PR wires up previously stubbed agent capabilities across MCP integration, memory, reasoning, reflection, collaboration, and orchestration, turning many TODOs into concrete implementations. The changes add real MCP server/agent flows, richer memory statistics, diff-based collaboration metadata, structured error handling, and more nuanced reasoning/reflection support.
Changes:
- Implemented full MCP server lifecycle and an MCP-capable agent entrypoint in
mcp_runner, including memory initialization and multi-modal reasoning engine setup. - Completed core memory plumbing for working, compressed, and cross-session storage, exposing aggregate stats via
IntegratedMemorySystem::get_stats. - Added Tree-of-Thought branch pruning, enhanced reflection confidence estimation and pattern detection, and richer orchestrator error handling with recovery, logging, and performance snapshots.
- Implemented a collaboration bridge diff generator that produces per-line change metadata for file/code operations.

serde_json::json!({ .. }).to_string() returns a String, but this block pattern-matches on Ok(event), which expects a Result and will not compile (expected enum Result, found struct String). Since to_string() cannot fail here, this should be simplified to a direct let event = ...; (or remove the if let Ok entirely) so that event is just the JSON string.

IntegratedMemorySystem::get_stats uses a fixed 1KB per item (estimated_memory = total_items * 1024) to estimate memory usage, which can be highly misleading for consumers of MemoryStats given the potentially large variability in item size. If memory_usage_bytes is surfaced in APIs or logs used for capacity planning, consider either computing a more accurate estimate based on actual stored sizes (e.g. aggregating size_bytes metadata where available) or explicitly documenting this as a rough heuristic so it is not mistaken for a precise value.

In CollaborativeOrchestrator::compute_diff_lines the DiffChangeType::Removed case emits the removed lines with content set to the old text but uses a 1-based line_number derived from the maximum of old/new line indices. For consumers that expect removed lines to be reported with respect to the original file’s line numbers, this can be misleading when additions and deletions shift subsequent line positions. If downstream consumers rely on accurate original line positions, consider using a diff algorithm (e.g. LCS/Myers) that tracks original and new line offsets separately, or at least document that line_number refers to a simple positional index in the unified diff rather than the original file.

CollaborativeOrchestrator::compute_diff_lines is currently a naive line-by-line comparer that treats any mismatch at position i as a modification, which can generate noisy Modified entries when a single insertion or deletion causes all subsequent lines to be flagged. If human reviewers or automated tools will rely on these diffs, it would be more robust to use an actual diff algorithm (e.g. Myers/LCS) so that insertions, deletions, and moves are detected accurately rather than as a cascade of modifications.

The new generate_code_diff / compute_diff_lines path introduces nontrivial behavior (file I/O plus diff semantics), but there are no tests exercising this logic even though this module already has tests (tests module at the bottom of the file). Adding focused tests that cover added/removed/modified line scenarios and missing-path/missing-content cases would help ensure the diff metadata stays correct as the collaboration protocol evolves.

The new error-handling and recovery flow (handle_execution_error, attempt_emergency_recovery, attempt_checkpoint_recovery, and execute_with_retry) introduces several branches based on error message content and retry counts, but there are no tests covering these paths even though this module already has unit tests. Adding targeted tests that simulate critical/high/medium/low error messages and transient vs. permanent failures would help ensure the correct ErrorRecoveryAction is selected and that the backoff logic behaves as intended.

There was a problem hiding this comment.
In CrossSessionPersistence::get_item_count, the SessionManager read guard (manager) is used to access manager.learned_patterns and manager.checkpoints, but SessionManager does not define either of these fields (it currently holds current_session, session_history, and active_sessions). This will not compile and also suggests a mismatch in what is being counted; if the intent is to count learned patterns and checkpoints, you likely need to read from learning_repository and/or aggregate checkpoint_data from the active/current sessions instead of accessing nonexistent fields on SessionManager.

IntegratedMemorySystem::get_stats holds read locks on working_memory, persistence, and compressor while awaiting on their async methods (e.g. working_mem.get_item_count().await), which keeps the RwLockReadGuards alive across .await points. This pattern can make it easier to introduce deadlocks or lock contention in the future as usage grows; a safer pattern is to clone or otherwise extract the underlying handles first, drop the outer locks, and then perform the awaited calls outside the read-locked section.

There was a problem hiding this comment.
The CLI defines mcp server --port with value_parser!(u16) (see crates/fluent-cli/src/cli_builder.rs:220-226), so sub_matches.get_one::<String>("port") will always return None and the code falls back to 8080. As a result, user-supplied ports are silently ignored (e.g., fluent mcp server --port 9000 still uses 8080), which breaks expected CLI behavior.
Useful? React with 👍 / 👎.
