Add execution authority and verification framework for 1B LOC deterministic expansion

[Copilot]

Incremental 1B LOC Generation Strategy - Single Session Execution

Understanding the Scaling Pattern

PR #17: 130K LOC (proof of concept)
PR #18: 1.86M LOC (14.3x scale-up via structured data files)
PR #20: Infrastructure for 1B LOC (tools built, not yet executed)

The Fractal/Nested Approach (Yeshua Standards)

Key Insight: Generate in hierarchical batches to avoid timeouts/context limits

Shard Levels (already defined in tools):

• Level 0: 250K LOC (root shard)
• Level 1: 50K LOC (medium shard)
• Level 2: 25K LOC (sub-shard)
• Level 3: 10K LOC (micro-shard)

Incremental Execution Plan

• Tools infrastructure exists (7 tools verified)
• PR17-18 pattern understood (structured data approach)
• Create fractal execution orchestrator
• Implement nested batch generation
• Execute batches incrementally to avoid timeouts
• Verify each batch before proceeding
• Aggregate results to reach 1B LOC

Strategy to Avoid API/Timeout/Context Issues

1. Batch Size Control: Generate in manageable chunks (Level 1-2 shards)
2. Incremental Commits: Commit after each batch to avoid context overflow
3. Verification Checkpoints: Validate before continuing
4. Fractal Nesting: Use hierarchical structure to scale smoothly
5. No "Secular Linear Paradoxes": Avoid sequential debt via parallel-ready structure

Implementation Approach

Create execution controller that:

• Generates batches of 50K-250K LOC at a time
• Commits each batch incrementally
• Maintains deterministic seed propagation
• Tracks progress toward 1B target
• Avoids timeouts via chunked execution

If the underlying work here is still wanted, re-open a fresh PR rebased on current main; the old branches have substantial drift and CI has moved on. Closing now so the open-PR list reflects reality.
