#	Blocker	Scope	Strategies	Evidence
1	Codegen expression emission correctness	✅ FIXED — Unary negation now routes through generateConditionExpression (clean inline). If-block variables promoted via NestedVariableScanner.ScanIfBlock in first pass	moon, aostoch	generator.go, nested_variable_scanner.go, variable_declaration_registrar.go
2	UDF/arrow body scope lacks built-in access	~~✅ RESOLVED — All built-in vars and functions accessible in arrow/UDF scope. Arrow codegen resolves 26 identifiers: close/open/high/low/volume/hl2/hlc3/ohlc4/hlcc4/tr/bar_index/time/time_close/time_tradingday/last_bar_time/timenow/dayofweek/dayofmonth/hour/minute/month/second/year/weekofyear/last_bar_index/na. Official Pine has ~60+ built-in variables across namespaces. Resolved built-in vars (15): time, time_close, time_tradingday, last_bar_time, timenow, dayofweek, dayofmonth, hour, minute, month, second, year, weekofyear, last_bar_index, na. Resolved namespaces (9): barstate.*, timeframe.*, syminfo.*, dayofweek.*, session.*, chart.*, dividends.*, earnings.*, math.*. Resolved functions: timeframe.change/from_seconds/in_seconds, timestamp(), year()/month()/dayofweek()/dayofmonth()/hour()/minute()/second()/weekofyear(), time(). All blocker items resolved.~~	ann, ultima, ut+, moon	builtin_identifier_registry.go, builtin_namespace_resolver.go, builtin_identifier_handler.go, builtin_access_scope.go, arrow_builtin_access_generator.go, builtin_usage_detector.go, time_series_lifecycle.go, session_series_lifecycle.go, generator.go, runtime/context/timeframe.go, calendar_handler.go, call_handler_calendar.go, call_handler_timeframe_func.go, inline_timeframe_change_handler.go, timeframe_change_codegen.go, runtime/calendar/calendar.go, runtime/calendar/timestamp.go, runtime/context/timeframe_boundary.go, runtime/context/timeframe_converter.go, time_handler.go, value_handler.go
3	Expression-position function dispatch gap	✅ FIXED — generator.go:generateVariableFromCall() now routes through CallExpressionRouter before TODO fallback (lines 2555-2562). All registered handlers (str.*, ticker.*, math.*, value.*, calendar.*, timeframe.*, color.*, strategy.*) now work in variable assignment expressions. ExpressionPositionDispatcher fallback routes expression-position calls through CallExpressionRouter. HoistableCallClassifier gates TAFunctionRegistry handlers for hoisting. RuntimeDynamic-period TA calls now hoisted via SupportsDynamicPeriod() dispatch (sma, ema, stdev, highest, lowest confirmed end-to-end; rsi/atr hoisted but rejected at handler level: handler_rsi_handler.go:27, handler_atr_handler.go:27). Per-statement interleaved calc emission prevents NaN ordering in hoisted calcs. security()/request.security() in expression position now hoisted through full evaluator via 2-gate classification (IsHoistable + requiresTempVar). IsSecurityFunction shared predicate consolidates 7 callsites. Still affects: unregistered ta.* (#5), array.* (#12), map.* (#13), request.* (non-security functions, #16). Remaining gaps: ta.rsi/ta.atr reject IsRuntimeDynamic() at handler level; multiple dynamic-period TA calls in same scope generate duplicate period := declarations	alpha (#5), zigzag (#10)	expression_position_dispatcher.go, hoistable_call_classifier.go, variable_init_call_filter.go, security_function_classifier.go, dynamic_period_support.go, dynamic_period_ta_generator.go, dynamic_period_emitters.go, handler_rsi_handler.go, handler_atr_handler.go, generator.go, call_expression_router_position_test.go
4	Computed period expressions unsupported	✅ FIXED — ComputedPeriod renders arbitrary expressions via exprGen.Generate(). Arithmetic (length/2), function calls (math.round(math.sqrt(length))), and compound expressions now supported	hull	period_expression.go, arrow_function_ta_call_generator.go, arrow_inline_ta_call_generator.go, inline_ta_registry.go
5	Incomplete ta.* function coverage	26 of 58 official ta.* members implemented (22 single-output + 4 tuple). Missing functions (32): alma, bbw, cci, cmo, cog, correlation, cross, falling, highestbars, hma, kc, kcw, lowestbars, max, median, min, mode, mom, percentile_linear_interpolation, percentile_nearest_rank, percentrank, pivot_point_levels, range, rising, roc, sar, supertrend, swma, tr (function overload), tsi, variance, vwma, wpr.

6	Color literal and function gaps	✅ FIXED — HexColor regex supports 8-digit RGBA. All 7 color.* functions implemented: color.new, color.rgb, color.from_gradient, color.r/g/b/t. ColorHandler + ColorFunctionRegistry + ColorCallHandler in router. Runtime in visual/color.go	max	color_handler.go, color_function_registry.go, call_handler_color.go, runtime/visual/color.go, grammar.go
7	strategy.* API surface incomplete	10 of 48+ official strategy.* functions implemented. Implemented (10): entry, close, close_all, exit, initial_capital, grossprofit, grossloss, wintrades, losstrades, eventrades. Missing order functions (3): strategy.order, strategy.cancel, strategy.cancel_all. Missing risk management (6): strategy.risk.allow_entry_in, strategy.risk.max_cons_loss_days, strategy.risk.max_drawdown, strategy.risk.max_intraday_filled_orders, strategy.risk.max_intraday_loss, strategy.risk.max_position_size. Missing trade introspection (31): strategy.closedtrades.* (18 functions: commission, entry_bar_index, entry_comment, entry_id, entry_price, entry_time, exit_bar_index, exit_comment, exit_id, exit_price, exit_time, max_drawdown, max_drawdown_percent, max_runup, max_runup_percent, profit, profit_percent, size), strategy.opentrades.* (13 functions: same set minus exit_*). Missing utility (3): convert_to_account, convert_to_symbol, default_entry_qty. Missing variables (28): equity, netprofit, position_size, position_avg_price, position_entry_name, opentrades, closedtrades, max_drawdown, max_runup, openprofit, account_currency, avg_trade, avg_winning_trade, avg_losing_trade, margin_liquidation_price, etc. Missing constants (14): strategy.cash, strategy.fixed, strategy.percent_of_equity, strategy.oca.cancel/none/reduce, strategy.commission.*, strategy.direction.*	hull, ultima	call_handler_strategy.go, runtime/strategy/strategy.go, runtime/strategy/aggregators.go, codegen/builtin_identifier_handler.go
8	input.* missing type handlers	✅ CLOSED — 13/13 implementable input.* handlers complete. input.enum requires enum keyword (language-level feature → #23)	max, ultima	input_handler.go, input_constant_extractor.go, input_type_resolver.go, input_declaration_resolver.go, color_constant_resolver.go
9	String functions (str.*)	✅ FIXED — 18/18 official str.* functions implemented via StringNamespaceHandler with full CallExpressionRouter integration. Implemented: str.tostring, str.tonumber, str.length, str.format, str.format_time, str.contains, str.pos, str.substring, str.lower, str.upper, str.trim, str.replace, str.replace_all, str.split, str.startswith, str.endswith, str.repeat, str.match. Strategy pattern with 8 code generators: SimpleStringGenerator, TwoArgStringGenerator, SubstringGenerator, ReplaceGenerator, RepeatGenerator, ToStringGenerator, FormatGenerator, FormatTimeGenerator. DRY architecture: StringArgumentParser for argument extraction, StringFunctionRegistry for signature validation, StringFunctionSignature for argument count enforcement. 147 test cases in call_handler_string_test.go validate all functions, argument variations, nested expressions, and router integration	ultima	call_handler_string.go, call_handler_string_test.go, string_argument_parser.go, string_code_generators.go, string_function_registry.go, string_function_signature.go, call_handler.go, call_handler_test.go
10	ticker.* namespace gaps	✅ CLOSED — 9/9 official ticker.* functions have handlers with full argument support: heikinashi, renko, kagi, linebreak, pointfigure, standard, new, modify, inherit. Session/adjustment/backadjustment/settlement_as_close modifiers encoded in ticker ID via runtime TickerID struct. Codegen resolves Pine modifier constants (session.regular/extended, adjustment.none/splits/dividends, backadjustment.inherit/on/off, settlement_as_close.inherit/on/off).
