direkturcrypto acf3943f80 fix(oneshot): use endDate instead of endDateIso for market expiry check 
The Gamma API returns two date fields:
  endDateIso = "2026-02-24"           ← date only, no time
  endDate    = "2026-02-24T06:35:00Z" ← correct close datetime

_parseEndTs() was preferring endDateIso, which parsed to midnight UTC
and was already in the past by the time any market opened during the day.
Both current and next-slot markets were therefore rejected as "already expired".

Fix: prioritise endDate (full ISO datetime) over endDateIso (date-only).

direkturcrypto 202bf98fe7 feat(oneshot): add ONESHOT_DEBUG verbose logging mode 
Adds a debug flag (ONESHOT_DEBUG=true / --debug / npm run oneshot-debug)
that surfaces the engine's internal decision process at every key step.

Debug output tags
─────────────────
  [DBG:FEED]   — Market discovery: every slug probed, API response status,
                 token IDs extracted, tick size fetched.
                 Throttled poll summary every 10 ticks per market showing
                 bid/ask/spread/mid/depth for both UP and DOWN sides.

  [DBG:GATE]   — Hard gate result every 5 evaluations per market:
                 TTE range, spread width, depth thinness, stale flag.
                 Shows exact gate fail reason or PASS confirmation.

  [DBG:FEAT]   — Feature breakdown for each side every 5 evals:
                 slope, imbalance, spread, retrace raw values plus
                 per-component scores and weighted total.

  [DBG:SCORE]  — Per-side qualify check: score vs threshold,
                 trend confirm flag, and QUALIFY / skip verdict.

  [DBG:SIGNAL] — Always logged (no throttle) when an ENTER signal fires.

  [DBG:HEART]  — 5-second heartbeat: active markets, per-market SM state,
                 dailyPnl, consecLosses, cooldownLeft, halted flag.

New script

direkturcrypto f074ca9ecb feat(oneshot): add Anti-Flip 5m microstructure execution engine 
Introduces a complete, event-driven execution engine for 5-minute
Polymarket UP/DOWN markets, implementing the Anti-Flip strategy spec.

Architecture
────────────
• EventBus          — central pub/sub bus connecting all services
• MarketFeedService — discovers 5m/15m markets via Gamma API, polls
                      CLOB orderbooks every 200–500ms, emits snapshots
• FeatureEngine     — maintains a 15s rolling buffer per market and
                      computes midSlope6s, retrace3s, imbalance, spread,
                      depthTop3 for both UP and DOWN sides
• SignalEngine      — hard gate checks (TTE, spread, depth, stale) then
                      weighted score (imbalance 35%, slope 35%,
                      spread 20%, retrace 10%) + trend confirmation
• ExecutionEngine   — limit-marketable FOK buy, market-sell FOK exit,
                      GTC limit-sell for TP; dry-run short-circuits
• RiskEngine        — consecutive loss cooldown, daily USDC loss cap,
                      session halt; all via explicit canTrade() gate
• PositionEngine    — per-market position state, TP/adverse/slope/time
                      exit evaluation on every snapshot tick
• StateMachine      — explicit state graph with guarded transitions:
                      IDLE → SETUP_READY → ORDER_PENDING → POSITION_OPEN
                      → REDUCE_ONLY → IDLE | COOLDOWN | HALTED
• Telemetry         — structured JSONL logger (data/oneshot_telemetry.jsonl)
                      recording decisions, orders, exits, and transitions

Runtime sequence (per market, per tick)
────────────────────────────────────────
A  Ingest snapshot (MarketFeedService)
B  Build features — rolling slope, retrace, imbalance (FeatureEngine)
C  Hard gate check — TTE [25,120]s, spread ≤ 0.02, depth ≥ minTopSize
D  Score + trend confirm → emit ENTER_LONG / ENTER_SHORT / NO_TRADE
E  Submit FOK limit-marketable at bestAsk
F  Fill handling — full fill / partial (reduce if TTE ≤ 25s) / timeout
G  Position management — TP, adverse (2-tick), slope drop (4s), time exits
H  Risk enforcement — P&L accounting, cooldown, daily halt

───────────
  npm run oneshot      — live trading  (DRY_RUN=false)
