Establishes mandatory standards for Mermaid diagrams in Blue documents: - Neutral theme required for dark/light mode compatibility - Leaf node counting for LR flow warnings (>3 nodes) - Plain text for architecture labels (no emoji color injection) - Shape semantics advisory for new diagrams - Auto-fix for theme declaration only (colors require manual review) Includes alignment dialogue with 10/10 tensions resolved across 3 rounds.

Round 0: Opening Arguments
🧁 Muffin
[PERSPECTIVE P01: Node counting heuristic fragility] The lint rule proposes counting "top-level nodes" to trigger warnings on LR diagrams with >3 nodes, but the RFC doesn't specify how to handle subgraphs with nested nodes or how to distinguish layout-relevant nodes from connection points.
[PERSPECTIVE P02: Premature lint crate assumption]
The RFC specifies implementation in a blue_lint crate that doesn't exist in the current codebase.
[TENSION T01: Auto-fix scope ambiguity]
Unclear whether auto-fix should strip prohibited fill:# directives entirely or just flag them.
🧁 Cupcake
[PERSPECTIVE P03: Emoji subgraph labels create platform-dependent rendering risks] Emojis render inconsistently across Mermaid versions, GitHub vs VS Code vs offline viewers. The RFC prohibits custom fills but doesn't address emoji color injection.
[PERSPECTIVE P04: 15-char edge label limit needs exception framework] No guidance for when technical precision demands more characters.
[TENSION T02: Shape semantics standardization conflicts with existing Blue document patterns]
🧁 Scone
[PERSPECTIVE P05: Lint implementation belongs in existing lint handler]
crates/blue-mcp/src/handlers/lint.rs already implements RFC header linting. Creating a separate crate introduces unnecessary overhead.
[PERSPECTIVE P06: Auto-fix for custom colors is unsafe without semantic preservation]
Custom fill:# colors encode semantic intent. Auto-stripping loses author intent.
[TENSION T03: LR-versus-TB rule assumes viewport constraints that may not hold]
🧁 Eclair
[PERSPECTIVE P07: Auto-fix will erase semantic color intent] In the wip spike, colors distinguish deployment environments that neutral grayscale won't preserve.
[PERSPECTIVE P08: Existing lint infrastructure already exists]
The blue_lint handler already detects RFC docs and runs header format checks.
[TENSION T04: Shape semantics table conflicts with existing hexagon usage]
🧁 Donut
[PERSPECTIVE P09: lint enforcement timing is backwards] Templates should generate compliant output first, then lint catches legacy violations.
[PERSPECTIVE P10: count_top_level_nodes is undefined complexity] Node counting in Mermaid is non-trivial due to subgraphs and multi-line definitions.
[TENSION T05: shape semantics conflict with emoji convention]
💙 Judge: Round 0 Synthesis
Converged: Neutral theme correct. Auto-fix for theme safe. Auto-fix for colors unsafe. Extend lint.rs.
Open: Shape semantics, emoji injection, LR counting, edge labels, timing.

|---|---|
| Theme | %%{init: {'theme': 'neutral'}}%% REQUIRED |
| Lint location | Extend crates/blue-mcp/src/handlers/lint.rs |
| Auto-fix scope | Theme prepend: auto-fix. Colors: error + manual migration |

RFC Amendments Required
- Replace "blue_lint crate" with "extend lint.rs handler"
- Split auto-fix: theme=auto, colors=error
- Add leaf node counting specification
- Make shape semantics table "Recommended Patterns"
- Add emoji guidance section (plain text for architecture)
- Make edge label limit advisory
- Reorder tasks: parallel track acceptable
