- Around line 5-27: Remove the "MetaTrader 5 (Agents)" subgraph from the mermaid
diagram as it references non-existent components (AAT_DataCollector and
AAT_MasterExecutor) and describes unimplemented MT5 integration. Update the
diagram to show only the actual implemented architecture: the Python-based
components HiveOrchestrator (referenced as Hive Orchestrator), BridgeServer
(referenced as Bridge Server), MetaBrain (referenced as MetaBrain), and
RiskManager (referenced as Risk Manager) that are confirmed to exist in
src/python/hive/coordinator.py, src/python/bridge/server.py,
src/python/brains/consensus.py, and src/python/execution/risk_manager.py
respectively. Ensure the flow accurately represents the current Python-only
architecture without any MetaTrader 5 connections.
- Around line 35-66: The Mermaid diagram block uses an invalid diagram type
`grid-layout` which is not supported by standard Mermaid syntax and will fail to
render. Replace the `grid-layout` declaration at line 35 with either `flowchart
TD` or `graph TD` to create a hierarchical diagram displaying the CPU
assignments. If a hierarchical layout is not suitable for the 20-CPU
architecture visualization, consider replacing the entire Mermaid diagram with a
Markdown table that shows CPU number and corresponding component assignments,
which will render reliably across all Markdown renderers.
- Around line 70-97: Update the Bayesian MetaBrain sequence diagram in the
Specialized Brains section to accurately reflect the actual implementation.
Replace the incorrect brain names (SMC Brain, VSA Brain, Trend Brain) with the
actual Brain class implementations: IndicatorBrain, TrendBrain, and
LiquidityBrain, and add RegimeBrain if applicable. Update the probability values
to match actual code outputs: TrendBrain produces P(E|H) = 0.85 for H4/D1
alignment, IndicatorBrain produces 0.65, and LiquidityBrain produces 0.80.
Change the risk validation reference from "7-Layer Risk Validation" to "7-Layer
Risk Stack" to match the naming convention used in
src/python/execution/risk_manager.py.

Diagram references components that don't exist in the codebase.
The diagram claims MetaTrader 5 integration with components AAT_DataCollector and AAT_MasterExecutor, but:
- AAT_DataCollector and AAT_MasterExecutor do not exist in the codebase.
- No MetaTrader 5 or MT5 integration code exists anywhere in the repository.
- Confirmed components that match the diagram:
- HiveOrchestrator (src/python/hive/coordinator.py)
- BridgeServer (src/python/bridge/server.py) — uses JSON (ujson) and async/TCP as documented
- MetaBrain (src/python/brains/consensus.py)
- RiskManager (src/python/execution/risk_manager.py)
The "MetaTrader 5 (Agents)" subgraph in the diagram is inaccurate or represents planned (not implemented) functionality. Update the documentation to reflect the actual architecture: the system currently integrates only Python-based components through the BridgeServer, with no active MT5 connection.

Mermaid grid-layout diagram type support 2024 2025
💡 Result:
Mermaid “grid layout diagram type” support (2024 vs 2025) 1) There is no general, cross-diagram “grid-layout diagram type” in Mermaid core for flowcharts/state/etc. Instead, Mermaid provides layout engines (e.g., dagre/elk/cose-bilkent) that control positioning, not a diagram type called “grid layout” for arbitrary diagrams [1][2]. 2) 2024–2025: The main “grid-like” layout relevant to Mermaid’s architecture diagrams is the architecture-beta layout system, which historically used heuristics that could break consistent grid alignment for certain edge arrangements. Mermaid documentation and issues note limitations around keeping a consistent grid pattern for architecture-beta diagrams (e.g., XY edges cannot extend more than 1 grid unit in X/Y; jumps > 1 can lead to inconsistent rendering) [3][4]. 3) 2025 (and then into later 2026): Mermaid added clearer documentation and error handling around those architecture-beta grid constraints, including explicitly documenting the “>2 grid spacing” error and throwing an error when edges traverse more than 1 grid unit [4]. This improves “grid layout” reliability, but it’s still specific to architecture-beta rather than a generic diagram type. 4) 2026+: Mermaid introduced an explicit declarative “grid layout” mechanism for architecture-beta diagrams via an align directive (and align row / align column). The PR states it allows authors to pin members to the same Y (row) or same X (column), and pairing row + column produces a clean grid layout; it also notes new reserved keywords in architecture-beta [5]. The architecture syntax docs further explain that fcose layout tuning knobs do not fix the underlying sibling/grid-map adjacency limitation, and point to the upcoming align row|column directive as the actual fix [6]. Block-diagram grids are a separate feature from architecture grid layouts. 5) Block diagrams have a built-in column-based layout and do support multi-column “grid-like” structures via the block diagram and columns N / column spans (e.g., :2). This is a different Mermaid diagram type (“block diagrams”), with its own syntax and grid behavior [7]. So, summarizing “Mermaid grid-layout diagram type support 2024 2025”: - 2024/2025: No universal grid-layout diagram type across Mermaid. For “grid-like” behavior, architecture-beta had limitations tied to how its underlying layout heuristic handled grid units, sometimes causing inconsistent rendering [3][4]. - 2024/2025: architecture-beta received improvements via documentation and explicit error handling for grid-unit traversal constraints (edges jumping more than 1 unit) [4]. - 2024/2025: Block diagrams did have grid/column layout support via the block diagram type’s columns syntax [7]. - The specific “clean grid” capability for architecture-beta using declarative align row|column is introduced in a later change (documented as “upcoming” in the architecture syntax docs and described in the align PR) [6][5].

Invalid Mermaid diagram type will prevent rendering.
Line 35 uses grid-layout, which is not a standard Mermaid diagram type. This will cause the diagram to fail to render in Markdown renderers that support Mermaid. Standard Mermaid diagram types include graph, flowchart, sequenceDiagram, classDiagram, stateDiagram, pie, architecture-beta, and block.
Consider using graph TD (like Diagram 1) or flowchart TD to visualize the 20-CPU layout as a hierarchical diagram. Alternatively, use a Markdown table to display CPU assignments reliably.
Alternative approaches for the CPU layout diagram
Option 1: Use flowchart TD with grouping
flowchart TD
subgraph S0["Supervisor Layer"]
CPU_0["CPU 0: Supervisor / Watchdog"]
end
subgraph S1["Orchestration"]
CPU_1["CPU 1: Hive Orchestrator"]
end
subgraph S2["Data Layer"]
CPU_2["CPU 2: Market Data A"]
CPU_3["CPU 3: Market Data B"]
end
CPU_0 --> CPU_1 --> S2
Option 2: Use a Markdown table instead
Replace the Mermaid diagram with a formatted table showing CPU assignments, which renders reliably.

Update diagram brain names and probability values to match actual implementation; clarify "7-Layer Risk Stack" naming.
The Bayesian MetaBrain sequence diagram contains accurate core logic but inaccurate implementation details:
✓ Verified:
- Bayesian update mechanism is implemented:
posterior = (weighted_p_e_h * prior) / p_e - Decision threshold P = 0.70 confirmed
- Veto mechanism (VETO, NEWS_VETO) implemented
- Risk validation with 7-layer checks exists (session, news safety, daily limits, drawdown, exposure correlation)
✗ Requires Correction:
-
Brain names don't match: Diagram shows "SMC Brain," "VSA Brain," "Trend Brain," but actual implementations are
IndicatorBrain,TrendBrain,LiquidityBrain. VSA is referenced in code comments and config but not as a dedicated Brain class producing EVIDENCE. -
Probability values are inaccurate:
- Diagram shows: SMC (0.85), VSA (0.72), Trend (0.65)
- Actual code: TrendBrain produces 0.85 (when H4/D1 aligned), IndicatorBrain produces 0.65 (RSI-based), no 0.72 value found
- Test case shows Trend 0.85 and Liquidity 0.80
-
Risk feature naming: Code comments call it "7-Layer Risk Stack" (src/python/execution/risk_manager.py:50), not "7-Layer Risk Validation." The actual implementation shows 5 documented checks (session, news, daily limits, drawdown, exposure).
Update the diagram to reflect the actual IndicatorBrain, TrendBrain, LiquidityBrain, and RegimeBrain classes with their actual probability outputs from code.
