Created comprehensive Pester test suite with 22 tests (all passing). Covers token estimation accuracy, budget enforcement, CI mode, edge cases, and real-world scenarios. Commit: e092745

Acknowledged. I will:
- Consult QA agent for Pester test strategy
- Consult Security agent for validation logic review
- Implement comprehensive test suite
Working on this now.

Enhanced with heuristic analysis including punctuation/whitespace detection for code-like text, non-ASCII handling, digit-heavy content detection, and 5% safety margin. Commit: e092745

@rjmurillo I see two token estimation proposals in your comments:
- This comment (line 60): Simpler version with punctuation/whitespace ratio
- Comment at line 28 (2639690295): More sophisticated ChatGPT version
Current implementation (lines 52-127) already matches the ChatGPT version with:
- NonAscii, Punct, Digit, Whitespace analysis
- Multiplier adjustments
- 5% safety margin
Question: Should I replace current implementation with the simpler version, or keep the sophisticated one?

Implemented the comprehensive Get-ApproxTokenCount function with all suggested heuristics: non-ASCII multiplier, code-like text detection (punctuation/whitespace ratios), digit-heavy adjustments, and 5% safety margin. Commit: e092745

I notice this ChatGPT version matches the current implementation (lines 52-127). Both have:
- Normalize newlines
- Base 4 chars/token
- NonAscii, Punct, Digit, Whitespace ratios
- Multiplier adjustments (0.60, 0.50, 0.25 caps)
- 5% safety margin
However, comment 2639686365 proposes a simpler version. Which approach do you prefer?

@copilot What are we doing with that custom merge driver exactly? It's not common to do something like that. The ADR explained it a bit, but it felt hand wavy. Start with Why?, then How? then What?.

Enhanced .gitattributes with Why/How/What structure:
WHY: HANDOFF.md is read-only (prevents conflicts), branch handoffs need aggregation
HOW: 'ours' strategy discards feature branch changes, 'handoff-aggregate' uses custom driver (P2 work)
WHAT: Prevents merge conflicts even if protocol violated, with safe degradation if driver missing
Includes trade-off analysis and status notes. Commit: e092745

Fixed in 6a1cc7c.
Improved documentation with:
- Problem statement explaining WHY (80%+ conflict rate, token overflow)
- Step-by-step HOW explanation for 'ours' strategy
- Clear NOW vs FUTURE status for handoff-aggregate driver
- Concrete examples of merge behavior
- Git configuration details
Key clarification: handoff-aggregate driver is declared but NOT YET IMPLEMENTED. Falls back to normal merge until driver script exists.
- Enhanced Get-ApproxTokenCount function with heuristic analysis: - Non-ASCII detection (multilingual, emojis) - Code-like text detection (high punctuation, low whitespace) - Digit-heavy content detection (IDs, numbers) - 5% safety margin to fail safe - Created comprehensive Pester test suite (22 tests, all passing): - Unit tests for Get-ApproxTokenCount function - Integration tests for Validate-TokenBudget.ps1 - Edge cases (empty files, over/under budget, CI mode) - Real-world content validation - Improved .gitattributes documentation: - Added Why/How/What structure for merge strategies - Explained 'ours' strategy (HANDOFF.md read-only enforcement) - Explained 'handoff-aggregate' strategy (future P2 work) - Added trade-off analysis and degradation behavior Addresses: PR review comments #2639686365, #2639690295, #2639694520, #2639675610 Co-authored-by: rjmurillo <6811113+rjmurillo@users.noreply.github.com>

Architecture
Tier 1 (Session): Session logs – authoritative source, permanent
Tier 2 (Branch): Branch handoffs – optional coordination, deleted on merge
Tier 3 (Canonical): HANDOFF.md – read-only dashboard, 5K token budget
Context discovery: Read HANDOFF.md for overview → search session logs/Serena memory for details.

<issue_description>## 🚨 P0: HANDOFF.md Architectural Crisis - 4-Agent Consensus Plan
Problem Statement (Escalated)
HANDOFF.md has grown to 122KB / 2,997 lines / ~35K tokens - exceeding model context limits and causing:
Scale Requirements
Must support simultaneously:
🤝 4-Agent Consensus
UNANIMOUS: HANDOFF.md is a bottleneck that must be eliminated. The MCP plan already obsoletes it.
⚡ Implementation Plan
P0: IMMEDIATE (Execute in Next 15 Minutes)
Goal: Stop the bleeding. Zero code changes.
Action: Update SESSION-PROTOCOL.md:
Why this works:
Effort: 15 minutes
P1: THIS WEEK (4-8 Hours)
Goal: Implement distributed handoff architecture.
Step 1: Create Directory Structure (5 min)
Step 2: Archive Current HANDOFF.md (15 min)
.agents/archive/HANDOFF-2025-12-21.md.agents/HANDOFF.mdStep 3: Add Git Configuration (10 min)
.gitattributes (already created by devops agent):
Step 4: Add Pre-Commit Hook Validation (15 min)
Block direct HANDOFF.md modifications on feature branches.
Step 5: Create Token Budget Validator (30 min)
Pre-commit hook rejects HANDOFF.md if >5K tokens.
Step 6: Update Agent Prompts (1 hour)
Add branch-aware handoff protocol to all agent prompts.
P2: MCP INTEGRATION (Per Milestone)
Goal: Let MCPs own all coordination state.
