| Subsystem | Role | Description |
| ------------------- | ----------- | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------ |
| **Event Loop Node** | Entry point | Listens for external events (schedulers, webhooks, SSE), triggers the event loop, and spawns sub-agents. Its conversation mirrors the Worker Bees conversation for context continuity. |
| **Worker Bees** | Execution | A graph of nodes that execute the actual work. Each node in the graph can become the Active Node. Workers maintain their own conversation and system prompt, and read/write to shared memory. |
| **Judge** | Evaluation | Evaluates Worker Bee output against criteria (aligned with Worker system prompt) and principles (aligned with Queen Bee system prompt). Runs on a scheduled event loop and escalates to the Queen Bee when needed. |
| **Queen Bee** | Oversight | The orchestration layer. Subscribes to Active Node events via the Event Bus, receives escalation reports from the Judge, and has read/write access to shared memory and credentials. Users can talk directly to the Queen Bee. |

| **Worker Bees** | Execution | A graph of nodes that execute the actual work. Each node in the graph can become the Active Node. Workers maintain their own conversation and system prompt, and read/write to shared memory. |
| **Judge** | Evaluation | Runs as an **isolated graph** alongside the worker on a 2-minute timer. Reads worker session logs via `get_worker_health_summary`, accumulates observations in a continuous conversation (its own memory), and emits structured `EscalationTicket` events to the Event Bus when it detects degradation. **Disengaged from the Queen at runtime** — the Queen receives escalation tickets only through Event Bus subscriptions, not via a direct connection. Criteria and principles align with Worker/Queen system prompts at design-time. |
| **Queen Bee** | Oversight | The orchestration layer. Subscribes to Active Node events via the Event Bus, receives escalation reports from the Judge, and has read/write access to shared memory and credentials. Users can talk directly to the Queen Bee. |
| **Sub-Agent Framework** | Delegation | Enables parent nodes to delegate tasks to specialized sub-agents via `delegate_to_sub_agent`. Sub-agents run as independent EventLoopNodes with read-only memory snapshots, their own conversation, and a `SubagentJudge`. They report progress via `report_to_parent` and can escalate to users via `wait_for_response`. Multiple delegations execute in parallel. Nested delegation is prevented. |

### Data Flow Patterns
- **External triggers**: Schedulers, Webhooks, and SSE events flow into the Event Loop Node's listener, which triggers the event loop to spawn sub-agents or start browser-based tasks.
- **External triggers**: Schedulers, Webhooks, and SSE events flow into the Event Loop Node's listener, which triggers the event loop to delegate to sub-agents or start browser-based tasks.
- **User interaction**: Users talk directly to Worker Bees (for task execution) or the Queen Bee (for oversight). Users also have read/write access to the Credential Store.
- **Worker-Judge loop**: Worker Bees inquire with the Judge after completing work. The Judge approves the output or escalates to the Queen Bee.
- **Pub/Sub**: The Active Node publishes events to the Event Bus. The Queen Bee subscribes for real-time visibility.
- **Judge monitoring (runtime-decoupled)**: The Judge runs as an isolated graph on a 2-minute timer. It reads worker session logs via tools, tracks trends in its continuous conversation, and publishes `EscalationTicket` events to the Event Bus when it detects degradation patterns (doom loops, stalls, excessive retries). The Queen receives these tickets as an Event Bus subscriber — there is no direct Judge→Queen connection at runtime.
- **Sub-agent delegation**: A parent Event Loop Node invokes `delegate_to_sub_agent` to spawn specialized sub-agents. Each sub-agent receives a read-only memory snapshot, a fresh conversation, and filtered tools from the Tool Registry. A `SubagentJudge` auto-accepts when all output keys are filled. Sub-agents report progress via `report_to_parent` (fire-and-forget) and can escalate to the user via `wait_for_response` through an `_EscalationReceiver`. Multiple delegations run in parallel; nested delegation is blocked to prevent recursion.
- **Pub/Sub**: The Active Node publishes events to the Event Bus. The Queen Bee subscribes for real-time visibility. Sub-agent progress reports are also published to the Event Bus.
- **Adaptiveness**: The Codebase modifies Worker Bees, enabling the framework to evolve agent graphs across versions.

## Tool Result Truncation & Pointer Pattern
Agents frequently produce or consume tool results that exceed the conversation context budget (web search results, scraped pages, large API responses). The framework solves this with a **pointer pattern**: large results are persisted to disk and replaced in the conversation with a compact file reference that the agent can dereference on demand via `load_data()`. This pattern extends into conversation compaction, where freeform text is spilled to files while structural tool-call messages are preserved in-place.

```
### How It Works
**1. Every tool result is saved to a file** (when `spillover_dir` is configured). Filenames are monotonic and short to minimize token cost: `{tool_name}_{counter}.txt` (e.g. `web_search_1.txt`, `web_scrape_2.txt`). JSON content is pretty-printed so `load_data`'s line-based pagination works correctly. The counter is restored from existing files on resume.
**2. The conversation receives a pointer, not the full content.** Two cases:
| Result size | Conversation content |
| ----------- | -------------------- |
| **≤ 30KB** | Full content + `[Saved to 'web_search_1.txt']` annotation |
| **> 30KB** | Preview (first ~30KB) + `[Result from web_search: 85,000 chars — too large for context, saved to 'web_search_1.txt'. Use load_data(filename='web_search_1.txt') to read the full result.]` |
**3. The agent retrieves full results on demand** via `load_data(filename, offset, limit)`. `load_data` results are never re-spilled (preventing circular references) — if a `load_data` result is itself too large, it's truncated with a pagination hint: `"Use offset/limit parameters to read smaller chunks."`.
**4. File pointers survive compaction.** When the conversation exceeds the context budget, structure-preserving compaction (`compact_preserving_structure`) keeps tool-call messages (which are already tiny pointers) and spills freeform text (user/assistant prose) to numbered `conversation_N.md` files. A reference message replaces the removed text: `"[Previous conversation saved to 'conversation_1.md'. Use load_data('conversation_1.md') to review if needed.]"`. This means the agent retains exact knowledge of every tool it called and where each result is stored.
**5. The system prompt lists all files** in the spillover directory on every turn. Data files (spilled tool results) and conversation history files are listed separately. `adapt.md` (agent memory / learned preferences) is inlined directly into the system prompt rather than listed — it survives even emergency compaction.
### Why This Pattern
- **Context budget**: A single `web_search` or `web_scrape` can return 100KB+. Without truncation, 2-3 tool calls would exhaust the context window.
- **Fewer iterations via larger nominal limit**: The 30KB threshold is deliberately generous — most tool results fit entirely in the conversation with just a `[Saved to '...']` annotation appended. This means the agent can read and act on results in the same turn they arrive, without a follow-up `load_data` call. Only truly large results (scraped full pages, bulk API responses) trigger the preview + pointer path. A tighter limit would force more round-trips: the agent calls a tool, gets a truncated preview, calls `load_data` to read the rest, processes it, and only then acts — each round-trip is a full LLM turn with latency and token cost. The larger limit front-loads information into the conversation so the agent makes progress faster.
- **No information loss**: Unlike naive truncation, the full result is always on disk and retrievable. The agent decides what to re-read.
- **Compaction-safe**: File references are compact tokens that survive all compaction tiers. The agent can always reconstruct its full state from pointers.
- **Resume-safe**: The spill counter restores from existing files on session resume, preventing filename collisions.

## Memory Reflection Logic
Agents in Hive maintain memory through four interconnected mechanisms: a durable working memory file (`adapt.md`), the conversation history itself, a structured output accumulator, and a three-layer prompt composition system. Together they form a reflection loop where outputs, judge feedback, and execution state are continuously folded back into the agent's context.

### How It Works
**1. Outputs trigger dual persistence.** When the LLM calls `set_output(key, value)`, two things happen simultaneously: the `OutputAccumulator` stores the value in memory and writes through to the `ConversationStore` cursor (for crash recovery), and `_record_learning()` appends a truncated entry (≤500 chars) to `adapt.md` under an `## Outputs` section. Duplicate keys are updated in-place, not appended.
**2. adapt.md is the agent's durable working memory.** It is seeded on first run with identity and account info. The agent can also write to it directly via `save_data("adapt.md", ...)` or `edit_data("adapt.md", ...)` — storing user rules, behavioral constraints, preferences, and working notes. Unlike conversation history, `adapt.md` is inlined directly into the system prompt every turn, so it survives all compaction tiers including emergency compaction. It is the last thing standing when context is tight.
**3. Judge feedback becomes conversation memory.** When the judge issues a RETRY verdict with feedback, that feedback is injected as a `[Judge feedback]: ...` user message into the conversation. On the next LLM turn, the agent sees its prior attempt, the judge's critique, and can adjust. This is the core reflexion mechanism — in-context learning without model retraining.
**4. The three-layer prompt onion refreshes each turn.** Layer 1 (identity) is static. Layer 2 (narrative) is rebuilt deterministically from `SharedMemory.read_all()` and the execution path — listing completed phases and current state values. Layer 3 (focus) is the current node's `system_prompt`. At phase transitions in continuous mode, Layer 3 swaps while Layers 1-2 and the full conversation history carry forward.
**5. Phase transitions inject structured reflection.** When execution moves between nodes, a transition marker is inserted into the conversation containing: what phase completed, all outputs in memory, available data files, agent memory content, available tools, and an explicit reflection prompt: *"Before proceeding, briefly reflect: what went well in the previous phase? Are there any gaps or surprises worth noting?"* This engineered metacognition surfaces issues before they compound.
**6. Shared memory connects phases.** On ACCEPT, the accumulator's outputs are written to `SharedMemory`. The narrative layer reads these values to describe progress. In continuous mode, subsequent nodes see both the conversation history (what was discussed) and the structured memory (what was decided). In isolated mode, a `ContextHandoff` summarizes the prior node's conversation for the next node's input.
### The Judge Evaluation Pipeline
The judge is a three-level pipeline, each level adding sophistication:
| Level | Trigger | Mechanism | Verdict |
| ----- | ------- | --------- | ------- |
| **Level 0** (Implicit) | Always runs | Checks if all required output keys are set and no tool calls are pending | RETRY if keys missing, CONTINUE if tools running |
| **Level 1** (Custom) | `judge` parameter set on EventLoopNode | User-provided `JudgeProtocol` examines assistant text, tool calls, accumulator state, iteration count | ACCEPT / RETRY / ESCALATE with feedback |
| **Level 2** (Quality) | `success_criteria` set on NodeSpec, Level 0 passes | LLM call evaluates recent conversation against the node's success criteria | ACCEPT or RETRY with quality feedback |
Levels are evaluated in order. If Level 0 fails (keys missing), Levels 1-2 are never reached. If a custom judge is set (Level 1), Level 2 is skipped — the custom judge has full authority. Level 2 only fires when no custom judge is set, all output keys are present, and the node has `success_criteria` defined.
