Sprint 2 (accounting + observability parity, PINK scope):
- Verified pink_clickhouse.py writes the 8 BLUE-legacy row families at
matching schema and that capital authority in pink_direct.step() is
solely kernel.account (no balance-poll overwrite in the hot loop).
- Report: prod/clean_arch/dita_v2/SPRINT2_ACCOUNTING_PARITY.md.
Sprint 3 offline groundwork (no exchange contact):
- Add _write_trade_exit_leg to pink_clickhouse.py: one BLUE-schema-faithful
trade_exit_legs row per exit leg, with isolated (non-cumulative) per-leg
deltas tracked via _leg_state (reset on ENTER). Closes the docstring gap.
- New offline suite test_pink_multi_exit_groundwork.py (3 passed):
* Flaw 4 — two-leg exit closes once, realized accrues per leg, closed
slot rejects further EXIT (no double-close).
* Overshoot invariant — a final EXIT requesting more than the remaining
size CLAMPS (size to 0, no oversell), retiring the Sprint 0 cumulative-
ratio risk empirically.
* trade_exit_legs delta + full BLUE column-set assertions.
- Persistence regression after edits: 10 passed.
BLUE untouched: no changes to dolphin.* / DOLPHIN_*_BLUE / nautilus_event_trader.py.
Live VST multi-leg run remains deferred pending explicit authorization.

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).
