ch_writer: _writer_violet (db=dolphin_violet) + ch_put_violet, the existing
per-strategy singleton pattern. bingx/journal: explicit violet entries in
_STRATEGY_DB_MAP/_SINK_MAP/_SINK_NAME_MAP — closes the hazard where the
unknown-strategy fallback routes venue journals into BLUE's dolphin DB
(regression-pinned in the new test, which documents the footgun for any
future strategy color). test_violet_namespace_isolation: violet sink
targets dolphin_violet exclusively; journal resolves violet explicitly;
Zinc region names for prefix violet disjoint from pink; persistence wired
with the violet sink routes only to dolphin_violet; HZ map-name contract
pinned for the C4 launcher. Shared-lib regression: 57/57 across PINK
kernel/runtime + BLUE tp_floor/malformed-open + bingx http safety.

67 production .py modules that the running PINK service imports but which
were never committed: prod/bingx/ (HTTP client, market/user streams,
journal, config), prod/clean_arch/ adapters/persistence/runtime/dita/dita_v2
production modules and their co-located tests. Rule going forward: every
module imported by launch_dolphin_pink.py / pink_direct.py must appear in
git ls-files. Excludes _backup dirs, __pycache__, and non-code files.

Root cause 1 (http.py): duplicate signature= in POST body — canonical_query
included signature key after build_signed_params injected it, then body
appended &signature= again. Fix: exclude 'signature' from canonical.
Root cause 2 (bingx_direct + http.py): HTTP retry sent same MARKET order to
backup URL (bingx.pro), which hits the same VST account. Without clientOrderId,
each retry opened a new SHORT position; EXIT BUY 10 only closed one. Fix:
restore clientOrderId in hyphen format p-{e/x}-{base36_ts}-{rand4} (pure
alphanumeric rejected by VST; hyphen format accepted). Adds max_retries_override
+ urls_to_try to _request_json for non-idempotent override path.
Root cause 3 (flat_and_start_pink): k.venue.connect() ran backend.connect()
inside asyncio.run() in a thread-pool. httpx session created there references
a dead event loop; order POSTs raise RuntimeError("Event loop is closed").
Fix: await adapter.connect() directly from main event loop.
Also: enter_wall_ms + tight _is_our_position createTime filter to separate
PINK's position from concurrent strategies on shared VST account. 1.5s
settle sleep before flat check.
New test suite test_bingx_http_safety.py: 20 tests covering idempotency,
retry correctness, backup-URL dedup, event-loop hygiene, signing correctness.
Live result: ENTER 290ms, EXIT 260ms — both sub-second. Position flat.
