feat: add milestone_type field to distinguish start/finish milestones

Browse Source 
Add milestone_type field to milestone queries that indicates whether
a milestone is a start milestone ('start') or finish milestone ('finish').

Changes:
- Add milestone_type column to activities table schema
- Parse milestone_type from XER TASK table (MS_Start/MS_Finish)
- Include milestone_type in list_milestones response
- Update contract tests for milestone_type field
- Update specs, contracts, and documentation

The milestone_type is determined by:
1. Explicit milestone_type field in XER (MS_Start -> 'start', MS_Finish -> 'finish')
2. Derived from task_type (TT_Mile -> 'start', TT_FinMile -> 'finish')

# Implementation Plan: Add Driving Flag to Relationships # Implementation Plan: Project Schedule Tools
**Branch**: `001-schedule-tools` | **Date**: 2026-01-06 | **Spec**: [spec.md](./spec.md) **Branch**: `001-schedule-tools` | **Date**: 2026-01-08 | **Spec**: [spec.md](./spec.md)
**Input**: Feature specification from `/specs/001-schedule-tools/spec.md` **Input**: Feature specification from `/specs/001-schedule-tools/spec.md`
## Summary ## Summary
Extend the existing XER MCP Server implementation to include the "driving" flag in all relationship query responses. This requires updating the database schema, XER parser, and query functions to extract and return the driving relationship indicator from Primavera P6 schedule data. Build an MCP server that provides 9 tools for querying Primavera P6 XER schedule data. The server parses XER files into an in-memory SQLite database and exposes tools for loading files, querying activities, relationships, milestones, critical path, and project summary. Uses Python 3.14 with the MCP SDK and follows TDD practices per the project constitution.
## Technical Context ## Technical Context

**Primary Dependencies**: mcp (MCP SDK), sqlite3 (stdlib) **Primary Dependencies**: mcp>=1.0.0 (MCP SDK), sqlite3 (stdlib)
**Storage**: SQLite in-memory database **Storage**: In-memory SQLite database (populated from XER files at runtime)
**Testing**: pytest, pytest-asyncio **Testing**: pytest>=8.0.0, pytest-asyncio>=0.24.0
**Target Platform**: Linux server (local MCP server) **Target Platform**: Local server (Linux/macOS/Windows with file system access)
**Project Type**: single **Project Type**: Single project
**Performance Goals**: Query response < 1 second, load < 5 seconds for 10k activities **Performance Goals**: Load + query XER files ≤5 seconds for 10,000 activities; query response <1 second

**Structure Decision**: Single project structure (existing). No new directories needed. **Structure Decision**: Single project structure with domain-specific organization: `models/` for data structures, `parser/` for XER file handling with pluggable table handlers, `db/` for SQLite storage layer, and `tools/` for MCP tool implementations. Tests follow contract/integration/unit hierarchy per constitution requirements.
## Complexity Tracking ## Complexity Tracking
> No constitution violations. Implementation is a focused enhancement to existing architecture. > **Fill ONLY if Constitution Check has violations that must be justified**
| Item | Assessment | No violations. All constitution principles satisfied.
|------|------------|
| Scope | Small - single field addition across 4 layers | ## Post-Design Constitution Re-Check
| Risk | Low - additive change, no behavior modification |
| Testing | Contract tests + unit tests for each layer | *Re-evaluation after Phase 1 design artifacts are complete.*
| Principle | Status | Verification |
|-----------|--------|--------------|
| **I. Test-First Development** | ✅ PASS | Contract tests defined in `tests/contract/` for all 9 tools; integration tests in `tests/integration/` |
| **II. Extensibility Architecture** | ✅ PASS | Table handlers pluggable via registry pattern; tools are modular functions; schema separates concerns |
| **III. MCP Protocol Compliance** | ✅ PASS | `contracts/mcp-tools.json` defines complete JSON schemas for all tools with input/output schemas |
| **IV. XER Format Fidelity** | ✅ PASS | Data model preserves all date precision; handles all 5 standard tables; driving flag computed accurately |
| **V. Semantic Versioning** | ✅ PASS | Version 0.1.0 in contract schema; following SemVer |
| **Technical Standards** | ✅ PASS | Type hints throughout models; ruff configured; pytest async mode enabled |
**Post-Design Gate Result**: PASS - Design artifacts align with constitution. Ready for task generation.

## Parallel Example: Phase 3 ## Implementation Details
```bash ### Milestone Type Determination
# First: Write all tests in parallel
Task: "Update contract test for list_relationships in tests/contract/test_list_relationships.py"
Task: "Update contract test for get_predecessors in tests/contract/test_get_predecessors.py"
Task: "Update contract test for get_successors in tests/contract/test_get_successors.py"
Task: "Unit test for driving flag computation in tests/unit/test_db_queries.py"
# Verify all tests FAIL (driving flag not yet implemented) In Primavera P6, milestones are identified by `task_type = 'TT_Mile'`. The distinction between Start and Finish milestones is typically:
# Then: Implement helper function 1. **XER Field**: Check for `milestone_type` field in TASK table (values: `MS_Start`, `MS_Finish`)
Task: "Create is_driving_relationship helper in src/xer_mcp/db/queries.py" 2. **Fallback**: If field not present, can infer from dates:
- Start milestone: Has only `target_start_date` (or start = end)
- Finish milestone: Has only `target_end_date` (or represents completion)
# Then: Update all queries in parallel ### Schema Change
Task: "Update query_relationships in src/xer_mcp/db/queries.py"
Task: "Update get_predecessors in src/xer_mcp/db/queries.py"
Task: "Update get_successors in src/xer_mcp/db/queries.py"
# Verify all tests PASS
```
---
## Implementation Strategy
### Driving Flag Computation (from research.md)
The driving flag is computed at query time by comparing dates:
```python
def is_driving_relationship(
pred_early_end: str | None,
succ_early_start: str | None,
lag_hours: float,
pred_type: str
) -> bool:
"""Determine if relationship is driving based on early dates."""
if pred_early_end is None or succ_early_start is None:
return False
# For FS: pred_end + lag = succ_start means driving
if pred_type == "FS":
# Parse dates, add lag, compare with 1-hour tolerance
...
# Similar logic for SS, FF, SF
return False
```
### SQL Query Pattern
```sql ```sql
SELECT r.*, -- Add to activities table
pred.early_end_date, milestone_type TEXT -- 'start', 'finish', or NULL for non-milestones
succ.early_start_date, ```
-- Compute driving in Python after fetch, or use CASE in SQL
FROM relationships r ### Query Change
JOIN activities pred ON r.pred_task_id = pred.task_id
JOIN activities succ ON r.task_id = succ.task_id ```sql
SELECT task_id, task_code, task_name,
target_start_date, target_end_date,
status_code, milestone_type
FROM activities
WHERE task_type = 'TT_Mile'
ORDER BY target_start_date, task_code
```
### Response Format
```json
{
"milestones": [
{
"task_id": "M001",
"task_code": "MS-START",
"task_name": "Project Start",
"milestone_type": "start",
