…ipped callsites TradingView keeps a per-requested-context history for user-defined-function series parameters: when a callsite is skipped on a bar (conditional execution), the parameter's series holds its last value rather than recording na, and history references read that held series per callsite. The generated code recorded na on skipped bars, desynchronizing every strategy whose UDF reads parameter history behind a condition. Evidence: browser-oracle discriminators udf-callsite-series-parameter-hold-last (four-model: TV=LLLL vs engine LSSL) and requested-context-udf-callsite-history- hold-last-and-last-invocation (eight-model: TV=LLLL vs LSLL); matrix codegen-dub4art-chart-udf-callsite-history-hold-last-full-e8: the fix cell is an exact closed-trade MATCH (digest e3ba507f) on the full 305-trade dub4art tape vs all-off DIVERGENCE; promotion promote-udf-holdlast-e829: PASS — band 1 entering (dub4art weak->excellent) / 0 leaving, corpus 312/312 zero regressions, tapes at corpus head 95074e0 unchanged.
