70+ granular tasks (T-001..T-809) across 9 phases, derived strictly from frozen detailed design. Each task is self-contained for context-isolated executor agents: file list, contract refs, applicable INV-1..5, dependencies, DoD/verify. Includes invariant injection (§A1), import graph (§A2), reference reuse map (§A3), validation gates (§A4), phase dependency summary (§A5). Co-Authored-By: Claude Opus 4.7 <noreply@anthropic.com>
