The v2 spec/plan (c35cc494) is the canonical guide. Phases 0, 1, 2 are
done in the branch. Phase 3a (mma.py, cd828e52) and Phase 3g (persona
to personas.py, d7872bea) are already committed; back-compat re-exports
exist in src/models.py. The remaining work: 3b (project.py), 3c
(project_files.py), 3d-3f + 3h-3i (6 merges), 4 (delete
AGENT_TOOL_NAMES), 5 (reduce models.py), 6 (verify + report).
The cruft_elimination track is no longer a blocker: the ProjectContext
+ 5 sub dataclasses are at models.py:797-873 (the cruft track merged
them in earlier). The v2 plan can extract them.
failcount state: 0/0 (prior reset via c35cc494).

v2 fixes v1 gaps that gave Tier 2 discretion:
1. THE 4-CRITERIA DECISION RULE (the taxonomy law):
- C1: Cross-system usage (consumed by >= 3 unrelated systems)
- C2: State machine / lifecycle
- C3: Test file already exists
- C4: Substantial size (> 30 lines OR > 5 fields)
- Rule: C1 OR C2 OR C3 -> DEDICATED FILE; ONLY C4 -> MERGE INTO DESTINATION; NONE -> KEEP
2. THE DATA/VIEW/OPS SPLIT (the GUI boundary):
- Data classes go in data files (src/<system>.py)
- View code (ImGui rendering) goes in src/gui_2.py
- Ops (operations on data) go with the data
- Exception: imgui_scopes.py is the EXCEPTION (Python with context managers)
3. ZERO TIER 2 DISCRETION:
- Every move is pre-decided in the spec
- Tier 2 executes, doesn't decide
- v1 had 22 commits because of exploration; v2 has 16 because the work is prescriptive
4. PRESERVED Pydantic PROXIES:
- _create_generate_request, _create_confirm_request, __getattr__ stay in models.py
- They're API-specific; moving them is out of scope for v2
Applied to all 11 classes in models.py:
- DEDICATED: Ticket, Track, WorkerContext, TrackState, TrackMetadata, ThinkingSegment -> src/mma.py (6 classes; C1+C2+C3+C4)
- DEDICATED: FileItem, Preset, ContextPreset, ContextFileEntry, NamedViewPreset -> src/project_files.py (5 classes; C1+C3+C4)
- DEDICATED: ProjectContext + 5 sub + config IO -> src/project.py (1+5+functions; C1+C3+C4)
- MERGE: Tool, ToolPreset -> src/tool_presets.py (C1 NO)
- MERGE: BiasProfile -> src/tool_bias.py (C1 NO)
- MERGE: TextEditorConfig, ExternalEditorConfig -> src/external_editor.py (C1 NO)
- MERGE: Persona -> src/personas.py (C1 NO)
- MERGE: WorkspaceProfile -> src/workspace_manager.py (C1 NO)
- MERGE: MCPServerConfig, MCPConfiguration, VectorStoreConfig, RAGConfig, load_mcp_config -> src/mcp_client.py (C1 YES, coupled to MCP)
- DELETE: AGENT_TOOL_NAMES (redundant with mcp_tool_specs.tool_names())
Net: 65 -> 61 files (possibly 60 if models.py eliminated)
16 atomic commits (down from v1's 22)
14 VCs (added VC13 + VC14: verify the 4-criteria rule and data/view/ops split are documented)
The git stash ban is in place at 3 layers (commit 6240b07b). The timeline-
is-immutable principle is explicit in the agent prompt. The next Tier 2
should not be able to corrupt files the same way.
