Snapshot PINK DITAv2 system + Sprint 0 flaw-fix verification
First commit of the previously-untracked PINK-on-DITAv2 migration system (execution moves to the Rust kernel; policy stays on legacy DITA, so Alpha Engine algorithmic integrity is preserved). BLUE is untouched. Sprint 0 (safety snapshot + flaw-fix verification, MARKET single-leg scope): - Verified Rust FSM fixes (flaws 2,4,10,11,13) by source read of lib.rs. - Hardened 5 vacuous/guarded assertions in test_flaws.py so each flaw test genuinely exercises its fix. Most important: Flaw 5 now asserts capital moves by EXACTLY realized PnL (was entering/exiting at the same price). - Offline suites: 533 passed, 0 failed (35 flaws + 402 kernel/accounting/ bridge + 96 runtime/persistence/multi-exit/restart/seams). - GATE PASS: MARKET-path-critical flaws 1,2,5 confirmed fixed + green. - Added SPRINT0_FLAW_VERIFICATION.md report and _rust_kernel/.gitignore (excludes Rust target/ build artifacts). LIMIT/partial-fill remain explicitly out of scope (MARKET-only bring-up). Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>
