v0.5.0 — Pine v6 HIGH+MEDIUM sprint (44% identifier coverage)

Pine v6 HIGH+MEDIUM Coverage Sprint

Headline: Pine v6 supported identifier surface grows from 40% to 44% fully-runs (380 → 418 of 941). Corpus parity 233/234 excellent (99.6%), zero regressions.

What's new

✅ Runtime additions (17 identifiers)

• Session predicates (Sprint A): session.ismarket, session.ispremarket, session.ispostmarket, session.isfirstbar(_regular), session.islastbar(_regular) — backed by new pine_session_is* helpers in session_time.hpp + per-bar state tracking
• VWAP bands 3-tuple (Sprint B): ta.vwap(src, anchor, stdev_mult) returning [vwap, upper, lower] via new VWAPBandsResult struct + running variance accumulator
• timeframe.main_period (Sprint E)
• strategy.max_contracts_held_all/_long/_short + strategy.eventrades (Sprint F)
• time_tradingday (Sprint G1) with DST-edge fallback for America/Havana, Australia/Lord_Howe

🔧 Transpiler additions (21 identifiers)

• chart.is_* (7): emit constants (true for chart.is_standard, false for others)
• timeframe.isticks: constant false
• backadjustment.* (3), settlement_as_close.* (3), adjustment.dividends/splits (2): integer passthrough to request.security
• syminfo.main_tickerid + syminfo.country (2 derived from tickerid via new helpers_syminfo.py)
• varip (1): treated as var (semantically equivalent in batch); transpile warning emitted (was previously hard-rejected)
• ticker.inherit + ticker.standard (2): same-symbol passthrough (was previously blanket-rejected)

⏭️ Parse-and-skip + na-accept (12 identifiers)

• Critical fix: syminfo.prefix, syminfo.root, syminfo.pricescale, syminfo.minmove — were silently emitting 0 (fields are NOT in SymInfo struct, contrary to prior audit); now correctly na<T>()
• 6 syminfo external-data fields (mincontract, current_contract, expiration_date, isin, sector, industry) accept-na with conditional-use warnings
• ~14 LOW-tier syminfo fields reclassified ❌→⏭️ (behavior unchanged)

❌ Hard-reject (7 identifiers; previously ❓ blanket-reject)

• ticker.heikinashi/renko/kagi/linebreak/pointfigure — chart-type modifiers (engine doesn't synthesize alt bars)
• ticker.new/modify — cross-symbol construction (engine only same-symbol MTF)

Tooling improvements

• pineforge-utils validator: Eigen auto-detect at homebrew/macports/apt paths (recovered 6 matrix probes); new engine_chart_timezone override key in inputs.json schema; skip corpus/validation/symbol-specified/ from default sweep
• pineforge-corpus: 6 new TV-parity probes (5 excellent + 1 excellent via 15m OHLCV override); 5 stock-symbol probes relocated to validation/symbol-specified/<SYMBOL>/ (blocked on pineforge-data); 5 maintainer-only smoke/expected-reject probes removed (coverage retained in codegen pytest)

Known issues filed

• #16 max_intraday_filled_orders cap-day boundary uses chart_timezone instead of exchange syminfo.timezone (blocked on pineforge-data; validator workaround in place)
• #17 Codegen: UDT with drawing-typed fields — read/write of omitted fields compile-fails (mixed UDT struct definition correctly filters drawing fields; field access not handled)

Sprint metadata

• 7 implementation agents merged (A/B/C/E/F/G1/G2) — each in isolated git worktree, parallel execution
• 6 PR-equivalent merges across 3 repos (engine + codegen + corpus)
• Total commits: 30 engine, 14 codegen, 22 corpus, 3 utils
• Zero engine regressions across full corpus sweep at each merge step
• Sprint regression report: docs/pine_v6_sprint_regression_report.md
• Coverage audit refresh: docs/pine_v6_coverage_detail.md

Compatibility

• ABI: no breaking changes; new helpers added (pine_session_is*, pine_time_tradingday, _decompose_bar_time_chart_tz)
• C ABI: no changes
• Codegen output: backward-compatible — existing probes recompile and pass without modification
