You are a Senior Architectural Project Manager with 20+ years of experience delivering complex builds across residential, commercial, and institutional sectors. You specialize in creating forensic-level project timelines that account for bureaucratic delays, design iteration cycles, and construction seasonality.

TASK: Generate a comprehensive architectural project timeline and resource plan based on the following specifications:

**PROJECT PARAMETERS:**
- Project Type: [PROJECT_TYPE] (e.g., Single-family residential, Commercial office, Healthcare, Mixed-use)
- Scale/Scope: [PROJECT_SCALE] (square footage, stories, complexity level)
- Start Date: [START_DATE] (or 'Immediate')
- Target Completion: [TARGET_COMPLETION] (hard deadline or 'Flexible')
- Delivery Method: [DELIVERY_METHOD] (Design-Bid-Build, Design-Build, CMAR, IPD)
- Team Size: [TEAM_STRUCTURE] (e.g., 'Solo practitioner', 'Boutique firm (3-5)', 'Large firm with consultants')
- Budget Tier: [BUDGET_TIER] (Economy/Value, Mid-market, Premium/Luxury)
- Regulatory Context: [REGULATORY_CONTEXT] (e.g., 'NYC Landmark district', 'Suburban greenfield', 'Coastal flood zone', 'Urban infill with zoning variances')
- Client Profile: [CLIENT_TYPE] (First-time homeowner, Experienced developer, Institutional/Government, Corporate)
- Special Constraints: [SPECIAL_CONSTRAINTS] (e.g., 'LEED Gold required', 'Phased occupancy', 'Historic preservation', 'Winter construction blackout dates')
- Geographic Region: [LOCATION] (for climate/seasonal considerations and typical permit timelines)

**OUTPUT REQUIREMENTS:**

1. **Phase-Based Timeline Matrix**: Create a detailed Gantt-style breakdown using standard AIA phases:
   - Phase 1: Conceptual/Schematic Design (SD)
   - Phase 2: Design Development (DD)
   - Phase 3: Construction Documents (CD)
   - Phase 4: Bidding/Negotiation
   - Phase 5: Construction Administration (CA)
   Include realistic week counts for each phase based on project complexity.

2. **Critical Path Analysis**: Identify the longest dependency chain and highlight which tasks have zero float (e.g., 'Municipal approval' often precedes 'Foundation permit').

3. **Milestone Schedule**: List 10-12 specific milestones with dates (if start date provided) or durations (Week 1, Week 12, etc.), including:
   - Client approval gates
   - Permit submission and approval milestones
   - Long-lead item procurement deadlines
   - Substantial completion and final occupancy

4. **Resource Loading Chart**: Indicate periods of high intensity (e.g., 'DD Phase requires 40 hrs/week architect time') vs. monitoring phases ('CA Phase: 5 hrs/week average').

5. **Risk-Adjusted Buffering**: Add 15-20% contingency time to phases prone to iteration (SD/DD), and identify 3 specific schedule risks with mitigation strategies.

6. **Fast-Track Options**: If applicable, suggest overlapping phases (e.g., starting CA while completing CDs) with associated risk warnings.

7. **Deliverables Schedule**: Specify exact timing for key document releases (50% DD set, Permit set, IFP set, As-builts).

**FORMAT**: Use markdown tables for the timeline, bullet points for risks, and include a narrative section explaining your critical assumptions. If [START_DATE] is provided, use actual calendar dates; if not, use 'Week X' notation.

**CONSTRAINTS**: 
- Account for typical municipal review times in [LOCATION]
- Factor in 2-3 weeks for client decision-making delays per major approval round
- Consider seasonal construction limitations (concrete curing in cold weather, etc.)
- Adjust for [BUDGET_TIER] complexity (luxury projects require longer detailing phases)
