+"""Shared, compiler-backed controls for the frozen v16/v17 C++ boundary.

+The ABI checks deliberately compile callers against the headers that name each
+epoch, then link them only.  A caller binary is never executed: a successful
+link proves an accepted pair and a failed link must name the other epoch's
+``BacktestEngine::broker_state_hash`` symbol.  This keeps the test tied to the
+real archives instead of a manifest that merely describes an intended pair.

-// (2026-01-09 14:30) pins the TV chronology: the opening check runs AT THE
-// ENTRY FILL — a same-bar priced exit closes only the remainder left after
-// the trim, and the trim itself fills at the RAW matched entry base (the
-// pnl-0 "Margin call" row), never at an adverse extreme. The arithmetic below
-// is process_margin_call's opening-affordability LONG branch verbatim
-// (opening budget on the position's snapped entry basis, floor-before-4x,
-// the sub-lot one-contract fallback); only its PLACEMENT moves, and only
-// when a priced exit would otherwise fill first on the entry's own bar.
-// Bars where no same-bar priced exit fills keep the established end-of-bar
-// event untouched, as do POOC close fills (no intrabar chronology exists
-// there) and the scoped SHORT opening event (its end-of-bar placement plus
-// adverse-retry pass is separately pinned).
-//
-// The event is consumed ONLY when a slice is actually booked: a no-deficit
-// evaluation leaves the pending event for process_margin_call exactly as

-
-
-// finding-430 (margin call on gap-open bars). TradingView's broker emulator
-// evaluates the margin requirement at every point of the synthesized
-// intrabar path, and the bar OPEN is the first such point. When a CARRIED
-// leveraged position (a short, or a leveraged long — anything with a finite
-// liquidation price) already breaches the requirement at the open, TV books
-// the forced-liquidation slice AT THE OPEN, with the quantity computed at
-// the open price:
-//
-//     qty_liq = 4 * floor((qty * P - equity(P)) / P)      P = bar.open
-//
-// (the usual floor-before-4x nibble with the sub-lot one-contract fallback),
-// and then re-checks the SURVIVOR at the bar's adverse extreme — so a single
-// bar can carry two "Margin call" rows: the open slice and the extreme
-// slice. The engine's process_margin_call ran once, at the end of the bar,
-// at the adverse extreme only, so an open-breach bar was liquidated at the
-// wrong price and with the wrong (extreme-computed) quantity.
-//
-// Fitted on the NASDAQ:AAPL 15m tapes (Lab findings 430/431, 8,414
-// "Margin call" events over 90 slugs, prices half-up-rounded to mintick):
-// every event whose position was already in deficit at the open fills AT
-// THE OPEN (1,020 open-gap events; the 7 remaining "extreme while the open
-// breached" events are the second slice of an open+extreme pair whose open
-// slice was the one-share fallback), 7,303 non-gap events fill at the
-// adverse extreme as before, and the open/extreme quantity rule is exact on
-// 8,403/8,414 (the 11 misses are one 2x-equity pyramid script). Exemplars:
-// dthomas1026 2025-04-23 13:30 UTC O=206.00/H=207.50 -> TV 4@206.00 (the
-// engine printed 8@207.50); benblackdiamond 2025-05-12 13:30 UTC -> TV
-// 1116@211.05 (open) + 3864 remainder (engine 1156@211.26 at the high);
-// alpha-wizard-wave-oscillator 2025-10-27 13:30 UTC -> TV 88@264.93 (open)
-// AND 12@266.66 (high) on the same bar.
-//
-// Placement: the open is the earliest point on the path, so the slice runs
-// at the broker-open boundary of dispatch_bar (right after the carried
-// FX rollover, BEFORE any resting order is evaluated at the open) and at
-// the first sub-bar open of the real-bar magnifier. None of the 507 carried
-// open-slice events in the tapes shares its bar with another exit AT the
-// open, so the open-slice-before-open-fills ordering is a modelling choice
-// consistent with TV's path chronology rather than a tape-pinned one. The
-// slice deliberately does NOT mark last_margin_call_event_bar_ /
-// intrabar_exit_margin_call_bar_: the survivor keeps its ordinary
-// adverse-extreme check (the chronological pre-exit hook or the end-of-bar
-// process_margin_call), which is TV's second same-bar slice. Bars whose
-// open does not breach are untouched, so on-tick feeds without open gaps
-// (the ETH corpus) stay bit-identical. The 1x long has no adverse-price
-// liquidation and keeps its fill-time affordability event; a COOF bar keeps
-// the established once-per-script-bar placement (no exemplar).

-//   - created on the SAME bar (created_bar) as the declined entry — its signal
-//     bar, not bar_index_;
-//   - created AFTER the declined entry (created_seq): a close created FIRST
-//     fires (chawarat's sell leg, R7 — and the sort processes it before the
-//     entry anyway);
-//   - against the HELD side (created_position_side == position_side_, still the
-//     held side at decline time, the reversal not yet applied);
-//   - FULL close only (qty_percent >= 100-eps && isnan(qty)); partial closes
-//     are excluded (no exemplar — R7/partial-close row) and documented.
-//
-// Ledger re-credit (design doc item 4): the deferred close debited
-// id_unclosed_qty_[<bare id>] at strategy.close CALL time. Re-credit it EXACTLY
-// ONCE, on the false->true flag transition, so a later close(id) on the still-
-// held position resolves a nonzero target and fires. The `continue` on an
-// already-flagged order makes a second same-bar decline idempotent (single

-            // TradingView-confirmed reversal declines against 2,325

-            // widening therefore does not blunt this arm's gate, it makes it
-            // inert: 81/81 reproducible declines AND 2,325/2,325 admits both sit
-            // inside [0, qty_step * admit_price), because an all-in reversal
-            // spends the whole equity by construction and its entire decision
-            // lives inside one lot-floor remainder. Measured on that tape:
-            // one-lot epsilon 2/94 declines caught (balanced accuracy 51.1 %);
-            // float-guard epsilon 86/94 caught with 6/2,325 wrongly cancelled

-            // only 1 of them above one lot).
-            //
-            // The lot-floor "coin flip" argument does not transfer to the

- * Carved out of the original monolithic engine source during the v0.1
- * file-split (phase 6) — the BacktestEngine implementation now spans the
- * src/engine_*.cpp family. Each function is a
- * direct translation of one PineScript strategy.* call into a pending
- * order placement (and possibly an immediate fill when
- * `process_orders_on_close` or `immediately=true` is set).
- *
- *   strategy_entry       - place a pending entry order (market/limit/stop)
- *   strategy_close       - close a position (full or partial, by id or all)
- *   strategy_close_all   - thin wrapper over strategy_close("")
- *   strategy_exit        - place a take-profit / stop-loss / trail
- *   strategy_cancel      - drop one pending order by id
- *   strategy_cancel_all  - drop all pending orders
- *   strategy_order       - low-level RAW_ORDER placement
- *
- * Order matching itself lives in process_pending_orders
- * (engine_fills.cpp); the actual fill mechanics are in
- * execute_market_entry / execute_market_exit / execute_partial_exit
- * (engine_orders.cpp).

-// strategy commands during the warmup span so TA / var accumulators
-// converge without polluting comparison output. But the gate is set to
-// ``TV first entry - input bar`` (see _trade_start_time_ms_from_tv in
-// the validator) which, on a 15m strategy fed 1m OHLCV, lands one
-// MINUTE before the first TV trade — far inside the script bar that
-// CONTAINS the first TV trade, but BEFORE the script bar that
-// PRECEDES it.
-//
-// A stop/limit placed on the immediately-preceding script bar (where
-// TV's first trade originates) is therefore dropped under the strict
-// gate, and the engine's first in-window trade fires several bars
-// later from a different placement entirely. Validation/62-same-id-
-// stop-cross-before-modify is the canonical victim: TV's 03-31 03:30
-// long entry was longFirst's 03:15 stop firing — pre-fix the 03:15
-// strategy.entry was gated, longModify at 03:30 armed a different
-// stop that fired hours later, and the validator's price-fallback
-// alignment then misaligned 64 in-window trades.
-//
-// Subtracting one script TF interval from the gate restores the
-// previous script bar's strategy commands (just enough to let
-// pre-window placements fire on the first in-window bar) without
-// re-introducing the 411 extra pre-window trades that an
-// unconditional bypass produces in continuously-firing strategies
-// like basic/volty-expan. The buffer matches TV's chart-bar
-// resolution rather than the validator-chosen input-bar resolution.
-//
-// Since round 7 the harness (scripts/run_strategy.py,
-// _tv_entry_emit_window) sets the gate to the chart-feed bar that
-// PRECEDES TV's first entry bar, walked over the feed it actually
-// runs — so a weekend, holiday or overnight session gap before the
-// first fill no longer hides the signal bar (six single-entry 1D/15m
-// tapes produced 0 trades on every candidate: ledger
-// log-20260905t054904z-a9baf07e). On a gapless feed that is the same

+This is the real immutable `engine_script_run_v16` / `native_order_v4` /
+`native_run_spec_v1` / `native_driver_v4` / native-consumer-v6 provider at the
+R4-D adapter-lowering base. The preparation tool builds the archived source
+with the current profile compiler/configuration; it never synthesizes a
+provider or executes ABI callers.
+
+The provider is intentionally the authentic predecessor of the live v17
+archive. The ABI matrices require v16↔v17 rejection in both directions while
+retaining historical v13/v14/v15 controls. Its sibling

+virtuals (`prepare_native_begin`, `on_native_bar_open`, `on_native_input`,
+`on_native_tick`)
+and the additive v17 value members, with no engine storage relocation.

+# R4-D L0 legacy-route oracle carriers
+
+Every `test_oracle_*.cpp` here is the immutable literal capture from engine
+`ab9714beccb62b796c122cf68986ec9e7dbf4a67`. They are source files, not
+standalone CTest targets: each is included verbatim by the switched-route twin
+listed below. The CTest aliases named `test_oracle_*` execute those twins.
+`ORACLE_TEST_SOURCES` is intentionally absent from `tests/CMakeLists.txt` so a
+dead source list cannot be mistaken for executable coverage.
+
+| Frozen carrier | Executing native-route twin |
+|---|---|
+| `coof` | `test_native_oracle_coof_l2` |
+| `day_key` | `test_native_oracle_day_key_l2` |
+| `deferred_any_witnesses` | `test_native_oracle_deferred_any_witnesses_l2` |
+| `deferred_birth` | `test_native_oracle_deferred_birth_l2` |
+| `frozen_size` | `test_native_oracle_frozen_size_full_l2` |
+| `fx` | `test_native_oracle_fx_l2` |
+| `magnifier_barstate` | `test_native_oracle_magnifier_barstate_l2` |
+| `magnifier_distribution` | `test_native_oracle_magnifier_distribution_l2` |
+| `more_than_64_fills` | `test_native_oracle_more_than_64_fills_l2` |

+| `pooc_immediate` | `test_native_oracle_pooc_immediate_l2` |
+| `relative_exit` | `test_native_oracle_relative_exit_l2` |
+| `reversal_close_only` | `test_native_oracle_reversal_close_only_l2` |
+| `reversal_later_tick` | `test_native_oracle_reversal_later_tick_l2` |
+| `reversal_replaced_percent` | `test_native_oracle_reversal_replaced_percent_l2` |
+| `reversal_same_bar_tx` | `test_native_oracle_reversal_same_bar_tx_l2` |
+| `short_seed` | `test_native_oracle_short_seed_full_l2` |
+| `short_seed_percent` | `test_native_oracle_short_seed_percent_full_l2` |
+| `stop_snapshot` | `test_native_oracle_stop_snapshot_full_l2` |
+
+`scripts/check_oracle_twin_census.py` uses Python `re` to require one direct
+include per carrier and to pin the explicit `CHECK` census. It rejects a
+hand-copied twin body. `scripts/check_oracle_sha256.py` authenticates the
+complete `tests/oracle/` tree against `tests/oracle.sha256`; changing a frozen
+literal therefore requires an intentional pin update and review.
+
+The four owner-internal carriers deleted with the old book (`deferred_any`,
+`fifo_cohort`, `reversal`, and `coof_first_open`) have per-file coverage rows
+in the R4-D deletion ledger. Their public observable literals are carried by
+the executing twins above; no legacy owner is retained just to compile them.

+ *
+ * TradingView has NO per-bar fill-event budget. The historical 4-tick path is
+ * O -> W1 -> W2 -> C (W1/W2 are the bar's two extremes in proximity order).
+ * Order eligibility on that path splits by provenance:
+ *
+ *   - Orders RESTING at bar start, and orders placed by the BAR-OPEN fill
+ *     recalc (the recalc chain triggered by a fill AT the open tick), get
+ *     STANDARD semantics: exact-level fills anywhere along the remaining path.
+ *   - Orders placed by a MID-BAR fill recalc ("cascade orders") are eligible
+ *     ONLY at the remaining EXTREME waypoints (W1/W2): market orders fill AT
+ *     the next extreme (or ROLL to next-bar open when only C remains);
+ *     stop/limit orders gap-fill ONLY at an extreme waypoint tick price (no
+ *     intra-segment exact-level interpolation, and NEVER at C). A cascade
+ *     order that does not fill this bar converts to a normal resting order.
+ *
+ * These fixtures pin the two divergences the fixed 4-event budget produced:
+ *   R1/R2 — cascade PRICED / MARKET orders over-thread onto the W2->C segment
+ *           and the C tick (the +302 class); the new rule holds them to the
+ *           remaining extreme or rolls them to the next bar.
+ *   R3    — the budget truncates legitimate busy-bar RESTING-order fills TV
+ *           allows (aureate's deficit direction); the new rule fills them all.
+ * The G-rows lock behaviour that must NOT change: bar-open-recalc standard
+ * semantics, the flag-off legacy path, and the magnifier (real lower-TF) path,
+ * which owns its own tick semantics and is scoped OUT of the cascade gate.

+ * test_exit_bracket_pending_entry_leg.cpp — TV binds exit brackets to ENTRY
+ * INSTANCES via from_entry, not to the net position.
+ *
+ * A strategy.exit re-issue MODIFIES every live leg carrying that exit id (each
+ * keeping its own binding) and ADDITIONALLY arms one new leg bound to the
+ * pending entry order whose id == from_entry, if one exists at that moment.
+ * The engine armed exactly ONE order per exit id, so a re-issue that coincided
+ * with a pending same-id entry under-reserved: two qty=1 brackets covered only
+ * 2 units of a position that became 4.
+ *
+ * Ground truth — thulashimohanr-prev-day-week-levels-or-vwap-strategy,
+ * pyramiding=2, ETH-USDT-USDT 15m (all times UTC). The three shapes below must
+ * hold SIMULTANEOUSLY; each one falsifies a different naive rule.
+ *
+ * (i)  2025-06-29 — LEG MULTIPLICITY. A 2u long carried from 06-28 with both
+ *      LongT1/LongT2 live; the 09:30 OR bar re-issues both brackets (stop
+ *      re-priced to orLow(06-29)=2441.78) while a same-id 2u entry is pending.
+ *      TV closes FOUR units at 2441.78 on the 14:30 stop, tagged T1/T2/T1/T2 —
+ *      a full bracket pair PER ENTRY INSTANCE, carried pair first (FIFO):
+ *          #153 T1 2441.78 q1  entry 2025-06-28 09:45 @2424.68
+ *          #154 T2 2441.78 q1  entry 2025-06-28 09:45 @2424.68
+ *          #155 T1 2441.78 q1  entry 2025-06-29 09:45 @2452.56
+ *          #156 T2 2441.78 q1  entry 2025-06-29 09:45 @2452.56
+ *      Engine pre-fix: only the carried pair closed; the added 2u collapsed
+ *      into one unprotected trade that survived to the 06-30 reversal.
+ *
+ * (ii) 2026-03-27 — THE COUNTER-CASE that refutes a blanket multiply. Same
+ *      shape (live carried Short bracket + pending same-id entry, both
+ *      brackets re-issued in the same block) but ShortT1 had already been
+ *      CONSUMED on 03-26 17:45, so it has no live leg and arms only the ONE
+ *      pending-entry leg. TV fires a single T1 at 10:30 closing exactly 1 unit
+ *      (the 03-26 remnant, FIFO). `reserved = qty * (open legs + pending
+ *      entries)` would close 2 units at 2003.30 and desync the rest of March —
+ *      a regression on a locus the engine already matches. Green both pre- and
+ *      post-fix by construction: it is the guard, not the repro.
+ *
+ * (iii) 2026-03-29 — NO ADMISSIBLE PENDING ENTRY. The third short is over
+ *      pyramiding=2 and TV rejects it, so the re-issue binds to nothing new:
+ *      ShortT1 (no live leg, no admissible pending entry) arms NOTHING because
+ *      the two live ShortT2 legs already reserve the whole position, and
+ *      ShortT2 re-arms BOTH its legs. The 11:00 stop @2003.61 closes 2 units
+ *      tagged "T2 Exit" / "T2 Exit" — the double-T2 label that only this model
+ *      reproduces. Needs the pyramiding-count fix (an entry the cap will
+ *      refuse at fill contributes no bracket leg).

+ * test_default_qty_signal_freeze.cpp — TradingView freezes DEFAULT (qty=na)
+ * percent_of_equity / cash market-order sizing at the SIGNAL bar's close;
+ * the market order fills at the next bar's open carrying the frozen qty.
+ *
+ * Pins (see frozen_default_market_qty in engine.hpp for the rule):
+ *   A. Reversal with close(S) != open(S+1): the new lot's qty equals
+ *      equity_S / close(S) where equity_S = capital + realized + open mark at
+ *      close(S) — computed with the OLD position still open. The pre-freeze
+ *      fill-time evaluation was wrong three ways at once (double-counted the
+ *      just-closed lot's PnL, marked open profit at the FILL bar's close, and
+ *      divided by the fill price); a frozen qty of exactly equity_S/close(S)
+ *      excludes all three.
+ *   B. Flat entry with a close→open gap DOWN: qty = equity_S / close(S), not
+ *      equity / open(S+1) — pins the divisor with no position in play.
+ *   C. Flat all-in (pct=100) zero-commission entry with a close→open gap UP
+ *      whose frozen-qty notional exceeds the sizing equity by more than one
+ *      lot is REJECTED at fill (design-cntvxiao-gap-reject): the frozen qty is
+ *      never re-sized, and the whole true-flat entry is silently dropped. The
+ *      freeze itself still never RE-SIZES on a gap — pin B (gap DOWN) and the
+ *      affordable cases keep filling the frozen equity_S / close(S) lot.
+ *   D. process_orders_on_close=true: signal bar == fill bar and fill price ==
+ *      close(S), so the frozen qty is identical to the legacy fill-time
+ *      computation — POC sizing is unchanged.
+ *   E. CASH default sizing freezes at close(S) too: qty = cash / close(S),
+ *      not cash / open(S+1).
+ *   H. An ordinary true-flat omitted-qty MARKET dispatch preserves the
+ *      already-quantized frozen quantity.  It must not apply qty_step a
+ *      second time and lose one lot at an exact binary boundary.
+ *   I. The adjacent explicit-qty shape still receives its ordinary single
+ *      qty_step application; the frozen-quantity exception does not widen.

+ *
+ * The market-entry affordability gate admits an order only when
+ *   required_margin = qty * close * pointvalue * fx * (margin_pct/100) <= equity.
+ * When a script declares currency=currency.XXX differing from the symbol's
+ * quote currency (e.g. currency.INR on a USDT-quoted perp), TradingView keeps
+ * equity in the account currency but converts the quote-currency notional via
+ * the account-currency FX rate before this comparison. The engine exposes that
+ * rate through the syminfo-metadata channel ("account_currency_fx"); it
+ * defaults to 1.0 (no-op) so the validation corpus is byte-identical.
+ *
+ * This pins:
+ *   A. FX 1.0 (default): a qty-1 long whose notional (600) fits inside equity
+ *      (1000) is ACCEPTED -> 1 closed trade.
+ *   B. FX 2.0: the same notional scales to 1200 > 1000 and the entry is
+ *      REJECTED -> 0 trades. Proves the FX factor reaches required_margin.
+ *   C. A non-positive / non-finite FX resets to the 1.0 default (accepted).

+// test_magnifier_distributions.cpp — replaces 6 deleted corpus probes that
+// exercised non-ENDPOINTS magnifier distributions (UNIFORM, COSINE, TRIANGLE,
+// FRONT_LOADED, BACK_LOADED, VOLUME_WEIGHTED).
+//
+// Those probes were removed because TradingView's broker emulator only walks
+// O,H,L,C endpoints — it cannot reproduce non-ENDPOINTS sample paths, so the
+// corpus probes were structurally untestable against TV. The pine-side
+// distribution kernels are still useful and still need regression coverage,
+// hence this engine-only fixture.
+//
+// Coverage strategy:
+//   * Use a synthetic 30-bar 15m feed at script_tf == input_tf == "15" so the
+//     engine takes the LEGACY synthesized-distribution path (per
+//     test_magnifier_real_bars.cpp::test_legacy_path_used_when_single_sub_bar,
+//     real-bar magnifier mode collapses every distribution to ENDPOINTS+4 once
+//     multiple sub-bars per script bar are fed in — the only path that can
+//     observe distribution-flag effects is the single-sub-bar legacy path).
+//   * For each distribution: assert the magnifier flag is honored in the
+//     report (bar_magnifier_enabled == 1, magnifier_sub_bars_total > 0,
+//     magnifier_sample_ticks_total scales with the configured sample count).
+//   * Assert determinism: rerun with identical inputs, identical trade list.
+//   * Assert distributions are NOT all equivalent: at least one pair must
+//     produce different trade prices, proving the distribution flag actually
+//     reaches the price-path sampler.
+//   * Volume-weighted is toggled via set_magnifier_volume_weighted().
+//
+// Sub-bar timestamp inspection: the public engine API does not expose the
+// per-sub-bar timestamps the magnifier walks, so we cannot directly assert
+// "UNIFORM samples are evenly spaced". Instead we (a) verify the kernel-level
+// timestamp layout in test_magnifier.cpp (existing) and (b) verify here that
+// the integrated engine actually changes its trade output across distributions
+// — which is the load-bearing behavioral contract from the user's point of

+ * POOC, but its effect on script-visible position state becomes visible only
+ * from bar i+1. Broker/order state (position_side_, position_qty_, trades_)
+ * mutates immediately as before — only the SCRIPT-facing accessor defers.
+ *
+ * Ground truth: data/probes/pf-probe-ki64-daypivot-crossover — TV places 0
+ * entries on the 1,278 exit bars (a flat-gated strategy.entry on a close_all
+ * bar is never placed); the pre-fix engine re-enters on 399/1,381 exit bars
+ * because close_all flips position_size to 0 mid-on_bar.
+ *
+ * R rows are RED vs worktree HEAD 8b5932f (engine flips visibility). G rows
+ * are characterization that must hold before AND after the fix:
+ *   - POOC=false is unchanged (the close is a deferred market exit that fills
+ *     next bar, so the position is never mutated mid-on_bar — no freeze needed).
+ *   - an entry gated on position_size != 0 placed BEFORE the close still fires.
+ *   - strategy.close(immediately=true) is DEFINED to reflect its fill at once,
+ *     so it is NOT deferred (the :3896 same-dir immediate-cancel pin holds).
+ *   - a NON-flat-gated opposite entry (reversal) still flips (affordable
+ *     reversal class: sharpstrat/raphaeltay).
+ *   - the freeze is scoped to the close bar: next-bar and post-run reads see
+ *     the real (post-close) position.

+ * test_deferred_flip_carry_close_only.cpp — regression for a deferred-flip
+ * carry priced ENTRY that flips the opposite position but must NOT open its
+ * own leg.
+ *
+ * Bug (pre-fix): a pending stop/limit ENTRY that reaches its trigger while an
+ * OPPOSITE position is live performs a FULL reversal (close the opposite,
+ * open the new direction) whenever ``created_position_side != FLAT``. The
+ * close-only bracket path (apply_entry_order_fill's ``close_only_opposite``)
+ * only fired for ``created_position_side == FLAT``. So a stop armed during a
+ * PRIOR position cycle — a same-id "S" stop placed while SHORT, that survives
+ * a flip to LONG and then triggers against that LONG — reopened a fresh SHORT
+ * at the (stale) stop level instead of just closing the long. TradingView
+ * closes the long and re-arms the entry (its open leg is superseded by the
+ * same-bar re-issue); the ungated engine emitted a phantom short.
+ * On corpus/validation/pyramid-deferred-flip-close-all-01 this was 25 phantom
+ * / one-bar-early shorts (countAbsDelta 22 → 2).
+ *
+ * Fix: the close_only_opposite gate is ``created_position_side != position_side_``
+ * (a reduce-only flip whenever the order was NOT placed in the cycle of the
+ * position it now reverses), and the created!=FLAT case routes through
+ * ``flip_market_position_to(..., close_only=true)`` which closes the whole
+ * opposite position and stays flat.
+ *
+ * A genuine SAME-cycle reverse (the stop was placed while already holding the
+ * position it flips: created_position_side == the reversed side) must STILL
+ * open the new leg — the second test guards that.
+ *
+ * Exemplar in the wild (covered by the corpus run, reproduced minimally here):
+ * pyramid-deferred-flip-close-all-01, the 2025-04-13 19:30 UTC phantom short —
+ * TV closes the long at the stale 1589.71 stop ("flip short stop") and opens
+ * NO short; the pre-fix engine opened a phantom short there.
+ *
+ * KNOWN APPROXIMATION (out of scope, no ground truth): the gate
+ * created_position_side != position_side_ approximates "the order predates
+ * this position instance". A double flip — created LONG, the position flips
+ * SHORT, then flips LONG again while the order is still pending — is
+ * misclassified as same-cycle (created LONG == current LONG) and would open.
+ * No export pins this case; left for a future rule-first cycle.

+ * test_same_tick_multi_entry_race.cpp — TradingView same-tick multi-entry
+ * fill semantics (audit rule R*, jevondijefferson-big-breakout-strategy).
+ *
+ * Shape under test: TWO strategy.entry blocks with DISTINCT ids sharing one
+ * gate (3 BOS blocks entering "Long"/"Short" + a Wyckoff block entering
+ * "Wyckoff Swing Long"/"Wyckoff Swing Short"), pyramiding=0 (engine
+ * pyramiding_=1), percent-of-equity sizing, each entry paired with a
+ * strategy.exit(from_entry=<its id>) bracket. When both blocks fire on the
+ * SAME bar, both market entries fill at the SAME tick (next bar's open).
+ *
+ * TV's behaviour — validated 26/26 against every in-window race in the
+ * jevondijefferson tv_trades.csv export (qty arithmetic to 1e-4, operative
+ * bracket prices to the cent; audit artifacts scorecard.py / qtytest.py /
+ * reversals.py, 2026-07-02 tv-ceiling audit):
+ *
+ *   R*: same-tick entries fill SEQUENTIALLY in script-call order, each at
+ *   plain percent-of-equity qty; reversal augmentation (close-opposite-
+ *   then-enter extra qty) attaches ONLY to the LAST same-direction entry
+ *   of the tick; pyramiding=0 rejects an entry executing while the
+ *   position is already in that direction (evaluated at execution time,
+ *   against the sequentially-updated position); the fill that crosses
+ *   zero / opens from flat owns the entry ID; strategy.exit(from_entry=X)
+ *   brackets bind to id X even when X's paired entry call was rejected.
+ *
+ * Observable TV trade-list rows per race class (this is what the engine
+ * must reproduce — TV reports the old lot's close as ONE row at the shared
+ * fill price, attributed to the FIRST closing order's signal):
+ *
+ *   A flat at fill:      first entry opens at q_plain and owns its id;
+ *                        the later entry is pyramiding-rejected.
+ *   B opposite |pos| > q: old lot exits in ONE row with exit signal =
+ *                        FIRST entry id; the new lot opens at q_plain
+ *                        under the LAST entry id (total traded |pos|+q).
+ *   C opposite |pos| < q: the FIRST entry's single plain fill crosses
+ *                        zero: old lot exits (signal = first id), the
+ *                        REMAINDER (q - |pos|) opens under the FIRST id;
+ *                        the later entry is pyramiding-rejected.
+ *   D same direction:    no entry executes; the live lot's bracket is
+ *                        refreshed via from_entry binding.
+ *
+ * Pre-fix engine behaviour (dual-lot desync seeds): the first entry fill
+ * took flip_market_position_to — closing the whole opposite position and
+ * opening a FULL q_plain lot under the FIRST id. Class B then bound the
+ * WRONG bracket (first id instead of last id); class C opened q_plain
+ * instead of the remainder (TV: 0.2262 / engine: 7.915 at the 2025-06-17
+ * 15:15 race), seeding multi-day tiny-qty stale-remainder chains.

+ * test_default_pct_stop_sizing.cpp — round 7, family K: TradingView's sizing
+ * and admission of a DEFAULT percent_of_equity (<= 100) strategy.entry(stop=)
+ * under margin simulation, pinned by four `lab tv` tapes on NYSE:F 15
+ * 2025-08-11..23 (2026-09-05, ledger note log-20260905t084529z-c7b22df1;
+ * tapes scratchpad/r7/pins/f15-stopsize-{pct100,pct50,short-only,short-m50},
+ * decoder scratchpad/r7/k/aht_rule.py: 121/126 ahtisham F@15 TV entries
+ * reproduced with qty and price, every non-fill) and by the ahtisham
+ * volatility-expansion F@15 first-divergence rows (scratchpad/r7/k/).
+ *
+ * The pinned rule (default_qty_type = percent_of_equity, pct <= 100,
+ * margin_long/short > 0, default process_orders_on_close):
+ *
+ *   1. SIZING at the call: qty = floor(equity * pct/100 / tick(level)) with
+ *      the level snapped to the tick directionally (buy stop ceil, sell stop
+ *      floor) — NOT at the close: pct100 fills 858 = floor(10,000 / 11.65)
+ *      and 854 = floor(10,000 / 11.70) (873 / 869 at the closes); pct50
+ *      shorts 450 / 444 / 441 = floor(0.5 eq / L); margin 50 shorts
+ *      901 / 886 / 880 = floor(eq / L).
+ *   2. PLACEMENT (family E) on that quantity: accepted iff
+ *      qty * tick(close) * margin%/100 <= strategy.equity, so an all-in sell
+ *      stop BELOW the close is never placed (floor(eq/L) * C > eq: 0 short
+ *      fills over the 3 touches of pct100, 0 fills on short-only — no
+ *      opposite-order/OCA effect) while a buy stop above the close always
+ *      is; a rejected placement is dropped and only the script's next call
+ *      re-issues it; a rejected same-id re-issue cancels the resting order.
+ *   3. FILL: the same quantity at the level on a touch, at the tick-rounded
+ *      open on a gap-through, admitted iff qty * tick(fill) <= equity
+ *      (08-19 13:30Z: 817 = floor(9,414.16 / 11.51) x 11.52 = 9,411.84 <=
+ *      9,414.16 fills where the close-sized 822 x 11.52 = 9,469 would not;
+ *      a first-bar short gap-through is never filled because the order was
+ *      never placed).
+ *   4. A level already at/beyond the close is a market-at-next-open order
+ *      sized at tick(close): ahtisham 2025-04-04 13:30Z close 9.335 -> 9.34,
+ *      1,043 = floor(9,742.34 / 9.34) filled 13:45Z @9.34 (TV: 88 margin-
+ *      called @9.44 + 955 stopped 15:00Z @9.52).
+ *
+ * Engine before this change (d9e15ab): KI-62 sized the stop at the FILL
+ * price and costed it at the bar OPEN (engine_fills.cpp
+ * stop_entry_margin_admission_declines), a next-open-only snapshot sized it
+ * at the CLOSE. That coincided with TV on every intrabar touch and diverged
+ * on every session-open gap: 18/18 first-bar SHORT gap-throughs filled that
+ * TV never placed (04-04 13:30Z 1,020 @9.32), 0/19 first-bar LONG
+ * gap-throughs filled of which TV fills 6.
+ *
+ * Feed bars are the registry's NYSE:F 15 (feed 80f404ae85ef, mintick 0.01,
+ * whole shares), UTC, `lab bars`. Tape times are UTC+8 in the CSVs; quoted
+ * here in UTC.

+ * test_aapl15_margin_brackets.cpp — round 7 family N: the NASDAQ:AAPL 15m
+ * near-miss singletons (algoai, shojiy, willowsportz, fast-scalper,
+ * therealbouga) — three engine mechanisms, all replayed on the registry's own
+ * NASDAQ:AAPL 15 bars (feed ae2b03d3736f) and NYSE:F 15 bars (feed
+ * 80f404ae85ef) with the tapes' capital and orders.
+ *
+ * M1 — campaign pin log-20260905t112243z-b6ddd126 (lab tv tape
+ *   scratchpad/r7/pins/aapl15-mcopen-willow): a forced-liquidation slice on a
+ *   bar whose OPEN already breaches margin is sized with the position MARKED
+ *   AT THE TICK-ROUNDED OPEN — slice = max(1, 4 x floor(x)),
+ *   x = (q x P - E(P)) / P with P = round_to_mintick(open) — the same
+ *   on-tick ledger the adverse-extreme cascade marks on. The engine marked
+ *   the raw half-tick open (196.135 -> 408 where TV prints 412 at 196.14).
+ *   A. willowsportz 04-22 13:30Z: 412 @196.14 (the whole tape row-for-row:
+ *      12 / 36 / 156 / 412 / 676 / 4165).
+ *   B. algoai 06-20 13:30Z (o 198.235): 64 @198.24, then the 'Short Exit'
+ *      stop 3803 @200.00 on the same bar (the engine printed 60 / 3807).
+ *
+ * M2 — note log-20260905t112259z-33f32db4: on a bar whose OPEN carries a
+ *   declined all-in reversal, TradingView's sequence is decline -> bracket
+ *   dormant -> margin slice -> REVIVE, so the resting stop is live again for
+ *   the rest of the bar; at an adverse-extreme cascade a revived marketable
+ *   bracket closes the remainder AT THE SLICE PRICE on the same bar.
+ *   C. algoai 10-30 13:30Z (lab tv tape aapl15-mcopen1-stop-algoai + the
+ *      probe's declined ema9/21 reversal): 1 @271.96 open slice, then the
+ *      'X' stop 2814 @273.69 AT ITS LEVEL (the engine left the bracket
+ *      dormant: 176 @274.11 and a next-bar close).
+ *   D. fast-scalper 07-21 13:30Z (probe rows TV#160/161): the declined
+ *      reversal keeps the 213.08 stop dormant across the O->L->H path; the
+ *      high 214.86 breaches -> 268 @214.86 'Margin call' AND the revived,
+ *      now-marketable stop closes 4621 @214.86 on the same bar (the engine
+ *      closed the remainder next bar @214.68: REVIVE-B skipped a re-issued
+ *      bracket carrying a frozen full-position qty).
+ *   E. control (lab tv tape aapl15-mcext-stop-scalper-b, no reversal): the
+ *      stop fills at its level 212.83 x4883, no 07-21 slice — 1 / 20 / 108 /
+ *      4883 row-for-row.
+ *
+ * M3 — note log-20260905t112315z-a234f071 (census 51/51 AAPL + 56/56 F
+ *   therealbouga entries, 0 exceptions): layered strategy.exit legs from one
+ *   entry — 'TP1' qty_percent=50 + the default 'TP2' (limit+stop) — split
+ *   EXACTLY 50/50, bound ONCE at the fill and unchanged by the per-bar
+ *   re-issues (strategy.entry re-issued too, refused by pyramiding=0) and by
+ *   which leg fires first. The engine lost the split whenever the legs were
+ *   armed on a REVERSAL bar: the partial froze against the OLD position
+ *   (~25% shape: 125/364 of 489) and a later re-issue then dropped it behind
+ *   the still-deferred 100% sibling (0% shape: 502 'S TP2').
+ *   F. therealbouga AAPL 05-07 13:30Z: long 236 -> short 502, re-issued
+ *      every bar; the 'S TP2' stop at 19:30Z closes 251 @196.10, 251 held.
+ *   G. therealbouga AAPL 06-24 14:30Z: short 250 -> long 490 (no re-issue):
+ *      'L TP1' 245 @203.26; the 06-25 reversal closes the other 245 @201.41
+ *      and its own 'S TP2' stop then closes 245 @202.61.
+ *   H. therealbouga F 08-08 13:45Z: short 4591 -> long 8890: 4445 @11.43 +
+ *      4445 @11.53 on 08-11 13:30Z; the flat-open 08-11 entry keeps its
+ *      4349/4349 split (the stop at 11.26 closes exactly half).

+/*
+ * test_bracket_lifecycle_declined_reversal.cpp — finding-311: exit-bracket
+ * LIFECYCLE across declined in-position reversal signals.
+ *
+ * TV rule set (stevenygabbyperez derivation, 162/162 episodes):
+ *   KILL     — a declined in-position opposite MARKET reversal (the KI-54/
+ *              KI-72 decline arms, the "tradeless reversal") cancels the live
+ *              position's standing PRICED strategy.exit brackets. Not the
+ *              "__close__" family, not stale exits bound to unfilled entries.
+ *   DORMANT  — a killed bracket never matches a fill (118/118 TV stop-skips),
+ *              but stays in the book.
+ *   REVIVE-A — a fresh same-(id,from_entry) strategy.exit re-issue replaces
+ *              the dormant bracket wholesale and arms the NEW call's prices.
+ *   REVIVE-B — a margin-call PARTIAL re-registers the surviving position's
+ *              dormant brackets at their LAST-ARMED (original) prices.
+ *   CASCADE  — if the margin-call event price already makes a revived stop
+ *              marketable, the WHOLE remaining position closes at that event
+ *              price through the bracket's id (TV books the "Margin call"
+ *              slice and the residual close at the same adverse extreme).
+ *
+ * Harness: modelled on test_declined_reversal_close_leg.cpp (Probe subclass,
+ * scripted per-bar actions; initial_capital 10000, PERCENT_OF_EQUITY pct=100,
+ * zero commission, qty_step 0). The canonical decline fixture is the same
+ * +1-gap open: LONG 100 @100, signal close 110 (eq 11000, frozen opposite qty
+ * 100), fill bar opens 111 -> required 11100 > 11000 -> KI-54 DECLINE.
+ *
+ * Matrix:
+ *   KILL      declined reversal kills the bracket; a same-bar stop touch does
+ *             not fill (RED pre-fix: the stop filled early).
+ *   DORMANT   later-bar touches never fill either; position held.
+ *   REVIVE-A  same-(id,from_entry) re-issue arms fresh prices and fills.
+ *   ADMITTED  admitted reversal unchanged (fix inert; flip books the trade).
+ *   REVIVE-B  margin-call partial revives the bracket at its original price;
+ *             it fills normally on a later bar.
+ *   CASCADE   revived stop marketable at the margin-call event price closes
+ *             the entire remainder at that price under the bracket's id.
+ *   R5        close_all co-queued with the declined reversal still fires
+ *             (the "__close__" family is excluded from the kill).
+ *   COOF      KI-60 kernel mirror: the dormant flag set mid-segment by an
+ *             earlier candidate's decline is caught at apply time (the COOF
+ *             kernel pre-classifies its candidates, so classify's Skip alone
+ *             cannot see it). RED without the apply-time mirror.

+ * KI-60: calc_on_order_fills historical broker scheduling.
+ *
+ * These fixtures intentionally exercise the semantic seams that a broad
+ * "run on_bar again after process_pending_orders" loop misses:
+ *   - one broker fill per recalc, with a monotonic O -> near -> far -> C path;
+ *   - the four historical fill-event budget (including exits, not just opens);
+ *   - orders born in a recalc can only inspect the current/remaining path;
+ *   - process_orders_on_close fills recalc at C without replaying the wick;
+ *   - historical recalc executions expose barstate.isnew/isconfirmed together;
+ *   - script state rolls back to the committed checkpoint, broker state does not;
+ *   - the flag-off path and an explicit false override retain legacy behaviour.

+ * KI-67 residual — strategy.exit cascade "R-cascade-gapjump" (Model S).
+ *
+ * PR#95 gave calc_on_order_fills ENTRY orders cascade eligibility (fill only at
+ * the remaining extreme waypoints), but that machinery never reached
+ * strategy.exit orders: the shipped engine rolls 100% of exits placed by a
+ * mid-bar fill recalc (even the ones whose level sits exactly at a waypoint).
+ * TradingView does not. A clean-room probe (pf-probe-ki67-exitlim-midseg,
+ * 4,851 TV trades) pins the exact rule, Model S:
+ *
+ *   After an intrabar fill at price ap triggers a coof recalc, the emulator
+ *   resumes the O->W1->W2->C proximity path from ap. An exit order placed at
+ *   that recalc, on the historical (non-magnifier) path:
+ *     (1) IN-FLIGHT leg (remainder ap -> leg-end waypoint W0): a level inside
+ *         the remainder in the trigger direction gap-fills SAME BAR at W0
+ *         (limits fill better than the level, stops worse). A terminal in-flight
+ *         leg (-> C) never fills.
+ *     (2) SUBSEQUENT legs (incl. terminal): continuous evaluation — the first
+ *         crossing fills SAME BAR at the EXACT level.
+ *     (3) otherwise it rolls to the next bar as an ordinary resting order.
+ *
+ * Geometry note (adjudication): a position's in-flight leg always moves in its
+ * ENTRY direction, so only the profit-side LIMIT is ever crossed in-flight;
+ * the adverse-side STOP is only crossed on a later, reversed leg (clause 2,
+ * exact-level). "In-flight stop" and "subsequent-leg limit" are the
+ * geometrically dead complements of that split — the rule spells them out for
+ * completeness, but directed exits never hit them. The R-rows below therefore
+ * realise "stop -> waypoint" as the confirmed subsequent-leg exact fill.
+ *
+ * Marketable-at-placement exits generally use the pre-existing
+ * coof_suppress_*_on_entry_bar mechanism (they roll), NOT a placement-price
+ * fill — see M1. R5-R7 pin the narrow exception for a marketable LIMIT born
+ * after a later same-O fill; G3 proves marketable STOP remains suppressed and
+ * G4 preserves the pre-refinement trailing-order path reach.
+ *
+ * R1-R4 are RED against b6e4e35; R5-R7 are RED against ada0ca1. G/M rows lock
+ * behaviour that must NOT change.

+/*
+ * test_close_all_coqueued_entry.cpp — M1v2 (NARROWED close-co-queue fix).
+ *
+ * After a DEFERRED full-close exit fills and flattens on a bar, the ordinary
+ * stale same-direction MARKET/ENTRY wipe keeps three independently pinned
+ * exceptions: an under-cap same-call-bar co-queue, a resting prior-bar pure
+ * LIMIT, and (for close_all only) a prior-bar under-cap pure STOP whose id still
+ * names a physically-live same-side lot when close_all is called. Everything
+ * else — different-id carries, stop-limits, close(id), and over-cap adds —
+ * remains in the wipe.
+ *
+ * Why the extra "over cap" term (vs the reverted M1, which used created_bar
+ * alone): the engine enforces pyramiding at FILL time, and the co-queued full
+ * close zeroes position_entry_count_ before the add fills, so the fill-time gate
+ * passes an add TradingView would have rejected at placement. The post-full-
+ * close wipe is the only site that catches those. M1's created_bar-only
+ * exemption un-cancelled over-cap adds → probe65 doubled (732→1463) and the
+ * composite bracket fell below strong. The narrowed rule snapshots the
+ * placement-time over-cap status on the PendingOrder and keeps only genuinely
+ * TV-admissible (within-cap) co-queues.
+ *
+ * Ground truth:
+ *   - corpus/validation/pyramid-deferred-flip-close-all-01 (pyramiding=4):
+ *     9 TV-only entries 0-30min after a 21:45 close_all, all UNDER cap
+ *     (event replay: max same-dir open = 2 < 4) → must survive (R-KEEP).
+ *   - corpus/validation/order-same-id-entry-close-same-bar-01 (pyramiding=1):
+ *     over-cap same-id add + close(id) co-queued → dropped 366/366 (G-DROP).
+ *   - corpus/validation/composite-bracket-cap-range-pending-stop-01
+ *     (pyramiding=1): over-cap strategy.entry(stop) re-armed on the bar a full
+ *     strategy.order exit flattens → dropped (G-DROP).
+ *   See data/progress/laneb-pyramid-closeall-diagnosis.md and the session
+ *   scratchpad m1-regression-diagnosis.md.
+ *
+ * NON-POOC harness: process_orders_on_close_ stays false, so close_all/close
+ * are DEFERRED market exits filling at the next bar's open (the probe's
+ * 21:45-call / 22:00-fill split), which is the code path carrying the bug.

+/*
+ * test_coof_open_recalc_context.cpp — what a calc_on_order_fills FILL RECALC
+ * sees, and how a default-sized market order it places is sized (round 7
+ * family M, officialjackofalltrades aureate BTC@1D; campaign note
+ * log-20260905t121513z-50167cb8, which CORRECTS the m1d-coof-ctx pin).
+ *
+ * Rule 1 — script context (unchanged engine behaviour, pinned here as a
+ * regression guard): TradingView executes the on-fill recalculation on the
+ * CURRENT bar's FINAL values — high/low/close/volume of bar k, bar_index k,
+ * dayofmonth of bar k, close[1] = bar k-1, barstate.isconfirmed TRUE — for a
+ * fill at bar k's OPEN and for an intrabar fill alike. Never bar k-1's series,
+ * never the open tick. Evidence: lab tv sensor tapes scratchpad/pins/
+ * m1d-coof-ctx2-btc (BINANCE:BTCUSDT 1D 2025-10-01..12-31, tv_trades sha256
+ * f2e8418e…) and m1d-coof-ctx2-f (NYSE:F 1D, gaps): four encoded orders fire
+ * in the first calc with position_size == 1 — inside the recalc after a market
+ * fill at O, or after an intrabar limit fill at close*0.995 — and 103/103
+ * firings decode as finals/k/k/prev/confirmed. The earlier m1d-coof-ctx sensor
+ * placed its order at an ordinary close calc (its L close fills in the recalc at
+ * the same open, so no fill ever happens at the ≡2 bar's open) and therefore
+ * never tested the context at all.
+ *
+ * Rule 2 — sizing (the engine change): a DEFAULT-sized percent_of_equity / cash
+ * MARKET order born in a fill recalc is sized by TradingView at ITS OWN FILL,
+ * not at the signal bar's close (the ordinary freeze) and not at the recalc's
+ * cursor. Evidence: scratchpad/pins/m1d-coof-size-btc (tv_trades sha256
+ * 7ee8712b…): "B", born in the second recalc at the 10-02 open and filled at
+ * W1 = the low 118279.31, has qty 845.4564 = 10% x 1e9 / 118279.31 (cursor O
+ * 118594.99 -> 843.2, the bar's close 120529.35 -> 829.7); thirteen entries
+ * born in a first-O recalc and filled at O size at O. The probe: TV 4 0.09245
+ * = 9802.56 / (106011.13 x 1.0001) at the 11-11 open fill (the engine froze
+ * 0.0951 at the 11-11 close 103058.99); TV 10 0.14674 at its W2 fill 69988.83
+ * (cursor W1 63913.27 -> 0.16069, close 67988.04 -> 0.15106).
+ *
+ * Both tapes are replayed on the registry bars (BINANCE:BTCUSDT 1D, feed
+ * 14b8e066225c; test_coof_open_recalc_context_data.hpp). Context: (a) the tape
+ * itself decodes to the registry bar's finals at all 45 firings, (b) the engine
+ * re-creates each firing's triggering fill (a carried 1-lot market order at O,
+ * or the 1-lot limit at close*0.995 — carried, or born in the open recalc when
+ * TradingView's fill price says so) and its recalc context encodes to the
+ * same four numbers, in a fill recalc, confirmed, with the trigger filled at
+ * TradingView's price. Sizing: (a) the tape's recalc-born rows fit the fill
+ * and its ordinary rows fit the signal close (both discriminated by BTC's
+ * one-cent open/close offsets), (b) the engine reproduces the first cycle
+ * (A at O, B sized at W1) and the JOAT rows TV 3/4 and TV 8/9/10 (entry and
+ * exit bar/price, quantity, net PnL). Controls: COOF off is byte-identical
+ * (the ordinary signal-close freeze), a close-calc placement inside a COOF
+ * run still freezes, and an intrabar fill recalc sees the finals and sizes
+ * its cascade entry at the W1 fill. On the pre-change engine the sizing
+ * assertions fail (0.0951 / 0.15103 / 0.15106 / 829.67 / 817.05) and every
+ * context assertion passes.
+ *
+ * Known, deliberately NOT asserted (cascade machinery, out of this change's
+ * scope, recorded in the campaign notes): TradingView fills EVERY market order
+ * born in the first-O recalc at O (S1..S4 and the close_all on 10-02), fills
+ * every sibling born in one mid-bar recalc at the same waypoint (S1..S4 at W1
+ * on 10-04), and rolls the close_alls born in the recalcs after those W1
+ * fills to the next open; the engine's KI-60/67 scheduler admits one more
+ * fill at O and one fill per waypoint. That is why the sensor tapes are not
+ * replayed row-for-row here.

+ * test_declined_reversal_close_leg.cpp — declined-reversal close-leg
+ * suppression (design-declined-reversal-close-leg.md).
+ *
+ * Cluster shape (traced, POOC=false): on a mutually-exclusive opposite signal
+ * while in a percent-of-equity all-in (pct=100) position, the strategy queues
+ *   strategy.entry(opposite)   [created FIRST]
+ *   strategy.close(current)    [created AFTER, same on_bar]
+ * pyramiding=0/1. Next bar the KI-57/KI-54 reversal-admission gate DECLINES the
+ * opposite entry at fill (fill_open > sizing_close by >= one mintick, qty_step
+ * 0), because an all-in flip's frozen notional sits within lot-floor slack of
+ * equity. TradingView refuses the whole reversal ATOMICALLY and HOLDS the
+ * position; the pre-fix engine let the co-queued strategy.close FILL anyway and
+ * went FLAT, then re-entered on a later mid-span signal TV no-ops (+1 cAbs
+ * each). The fix: when the reversal decline fires, the same-bar, later-created,
+ * held-side FULL strategy.close leg it was paired with is suppressed too.
+ *
+ * Harness: modelled on test_margin_admission_gate.cpp (Probe subclass; scripted
+ * per-bar actions). initial_capital 10000, PERCENT_OF_EQUITY pct=100, zero
+ * commission, margin_call disabled, qty_step_=0 (so a +1-mintick fill-gap
+ * DECLINES the reversal — at qty_step_>0 one tick ADMITS per KI-54 pin H). All
+ * decline fixtures gap the fill bar +1 (>= one mintick) above the signal close.
+ *
+ * RED/GREEN matrix (design doc):
+ *   R1 declined reversal suppresses same-bar later-created full close (RED).
+ *   R2 admitted reversal unchanged (entry fills; close no-op).
+ *   R3 close WITHOUT a paired reversal fires.
+ *   R4 follow-up close on a DIFFERENT bar fires (one-shot binding) + ledger
+ *      re-credit proof (post-fix the deferred close's consumed id-ledger is
+ *      restored so a later close(id) can fire).
+ *   R5 close_all + declined reversal: characterization freeze (NOT suppressed).
+ *   R6 same-direction decline (probe65 shape) + co-queued close: close FIRES.
+ *   R7 close created BEFORE the entry (chawarat sell leg): fires.
+ *   G  two declined reversals same bar -> idempotent suppression.
+ *   G  partial close excluded (not suppressed).
+ *   G  multiple pending orders: only the matching close is suppressed.
+ *   G  strategy.exit bracket NOT suppressed (+ call-time cancel caveat).
+ *   G  pin-D fixture (declined reversal, NO co-queued close) unchanged.
+ *   G  COOF-kernel cross-check (calc_on_order_fills=1) — RED in the KI-60
+ *      kernel, same bug/other fill loop.
+ *   G  POOC inertness (process_orders_on_close=1: no deferred close exists).

+ * test_default_pct_stop_sizing.cpp — round 7, family K: TradingView's sizing
+ * and admission of a DEFAULT percent_of_equity (<= 100) strategy.entry(stop=)
+ * under margin simulation, pinned by four `lab tv` tapes on NYSE:F 15
+ * 2025-08-11..23 (2026-09-05, ledger note log-20260905t084529z-c7b22df1;
+ * tapes scratchpad/r7/pins/f15-stopsize-{pct100,pct50,short-only,short-m50},
+ * decoder scratchpad/r7/k/aht_rule.py: 121/126 ahtisham F@15 TV entries
+ * reproduced with qty and price, every non-fill) and by the ahtisham
+ * volatility-expansion F@15 first-divergence rows (scratchpad/r7/k/).
+ *
+ * The pinned rule (default_qty_type = percent_of_equity, pct <= 100,
+ * margin_long/short > 0, default process_orders_on_close):
+ *
+ *   1. SIZING at the call: qty = floor(equity * pct/100 / tick(level)) with
+ *      the level snapped to the tick directionally (buy stop ceil, sell stop
+ *      floor) — NOT at the close: pct100 fills 858 = floor(10,000 / 11.65)
+ *      and 854 = floor(10,000 / 11.70) (873 / 869 at the closes); pct50
+ *      shorts 450 / 444 / 441 = floor(0.5 eq / L); margin 50 shorts
+ *      901 / 886 / 880 = floor(eq / L).
+ *   2. PLACEMENT (family E) on that quantity: accepted iff
+ *      qty * tick(close) * margin%/100 <= strategy.equity, so an all-in sell
+ *      stop BELOW the close is never placed (floor(eq/L) * C > eq: 0 short
+ *      fills over the 3 touches of pct100, 0 fills on short-only — no
+ *      opposite-order/OCA effect) while a buy stop above the close always
+ *      is; a rejected placement is dropped and only the script's next call
+ *      re-issues it; a rejected same-id re-issue cancels the resting order.
+ *   3. FILL: the same quantity at the level on a touch, at the tick-rounded
+ *      open on a gap-through, admitted iff qty * tick(fill) <= equity
+ *      (08-19 13:30Z: 817 = floor(9,414.16 / 11.51) x 11.52 = 9,411.84 <=
+ *      9,414.16 fills where the close-sized 822 x 11.52 = 9,469 would not;
+ *      a first-bar short gap-through is never filled because the order was
+ *      never placed).
+ *   4. A level already at/beyond the close is a market-at-next-open order
+ *      sized at tick(close): ahtisham 2025-04-04 13:30Z close 9.335 -> 9.34,
+ *      1,043 = floor(9,742.34 / 9.34) filled 13:45Z @9.34 (TV: 88 margin-
+ *      called @9.44 + 955 stopped 15:00Z @9.52).
+ *
+ * Engine before this change (d9e15ab): KI-62 sized the stop at the FILL
+ * price and costed it at the bar OPEN (engine_fills.cpp
+ * stop_entry_margin_admission_declines), a next-open-only snapshot sized it
+ * at the CLOSE. That coincided with TV on every intrabar touch and diverged
+ * on every session-open gap: 18/18 first-bar SHORT gap-throughs filled that
+ * TV never placed (04-04 13:30Z 1,020 @9.32), 0/19 first-bar LONG
+ * gap-throughs filled of which TV fills 6.
+ *
+ * Feed bars are the registry's NYSE:F 15 (feed 80f404ae85ef, mintick 0.01,
+ * whole shares), UTC, `lab bars`. Tape times are UTC+8 in the CSVs; quoted
+ * here in UTC.

+ * test_dropped_reversal_mc_first.cpp — round 7 family M, mechanism 2a: on a
+ * bar whose OPEN carries a MARKET reversal that admission DROPS (its same-bar
+ * strategy.close voided), the position's standing stop bracket is dormant for
+ * the bar (finding-311), TradingView evaluates the margin call at the bar's
+ * adverse EXTREME first, and the revived bracket then closes the remainder AT
+ * THAT EXTREME on the same bar — not at its level, not on a later bar.
+ *
+ * Sources: campaign pin "PINNED (dropped-reversal bar: margin call first,
+ * stop fills at the extreme; round 7 family M rhyme17)" 2026-09-05 11:16Z
+ * (log-20260905t111645z-e1783b94) and the "round 7 family M mechanism 2/7"
+ * note; lab tv tapes scratchpad/r7/pins/m1d-mcbar-stop-{rev,norev}
+ * (OANDA:XAUUSD 1D 2025-06-01..08-01, ws-report-v1, rangeProof covered;
+ * tv_trades.csv sha256 ed4c62d6... / 3c901d1b...); the rhyme17
+ * trendline-and-horizontal-breakout XAUUSD@1D probe rows TV 3/4; the family-N
+ * mechanism-2 pin (aapl15-mcopen1-stop-algoai) as the OPEN-slice control.
+ *
+ * The pinned bar: 2025-07-13 21:00Z, O 3362.375 H 3375.085 L 3341.09
+ * C 3343.755 (bearish, high first), a 2.92-lot short @3322.825 (100% of
+ * 10,000 at the 06-23 21:00Z close, filled at the 06-24 open, trimmed 0.04
+ * @3337.205 on its entry bar and 0.04 @3358.085 on 06-30), its stop resting
+ * at avg + 47.5 = 3370.325 — BETWEEN the open and the high.
+ *
+ *   norev (no reversal issued): the stop precedes the extreme on the path,
+ *         so it fills AT ITS LEVEL 3370.325 x2.92 and there is no margin
+ *         call (finding-308 chronology: exit first, tie or earlier).
+ *   rev   (strategy.entry Long + strategy.close("Short") at the 07-10 21:00Z
+ *         close, dropped at the 07-13 open: E_s 9902.1, Q 2.95 x 3362.375 =
+ *         9919 > E_s; the close voided): "Margin call" 1.0 @3375.085 THEN
+ *         "Short Exit" 1.92 @3375.085 — both at the HIGH, on the same bar.
+ *
+ * The engine (8d9ec8d) sliced 1.0 @3375.085 but never filled the stop that
+ * bar; the re-issued stop filled two bars later 07-15 21:00Z @3370.537
+ * (-91.61 vs TV -100.34), the seed of rhyme17's equity knock-ons.
+ *
+ *   A. rev tape row-for-row (4 rows) and the 07-14 pair by name.
+ *   B. norev tape row-for-row (3 rows): the stop at its level, no slice.
+ *   C. The rhyme17 probe shape — the bracket carries a limit AND a stop and
+ *      is re-issued every bar (frozen whole-position qty): the same 07-14
+ *      pair as A.
+ *   D. Family-N mechanism 2 control (aapl15-mcopen1-stop-algoai): the
+ *      declined reversal on an OPEN-slice bar leaves the bracket live and it
+ *      fills AT ITS LEVEL — 1 @271.96 then 'X' 2814 @273.69 — unchanged. The
+ *      pinned difference between N and M-2a is WHERE the slice comes: at the
+ *      open (the bracket revives at the open, rests, fills at its level) or
+ *      at the extreme (it revives there, already marketable, fills there).
+ *   E. Synthetic controls (mintick 0.01, 1-share lots):
+ *      E1 a declined reversal with NO deficit at the extreme: the dormant
+ *         stop does not fill on that bar (finding-311) and the fresh
+ *         re-issue fills at its level on the next touch;
+ *      E2 a declined reversal on a LOW-first bar of a short (the extreme
+ *         comes AFTER the stop's level on the path): the slice and the
+ *         bracket fill still both book at the extreme — the dormant bracket
+ *         cannot fill before the revive;
+ *      E3 the same with the bracket issued ONCE (no re-issue): the pair's
+ *         close held it dormant at placement rather than cancelling it, so
+ *         the cascade's revive still finds it;
+ *      E4 an ADMITTED reversal pair: the close fills at the open, the entry
+ *         flips, and the held bracket is purged with its cycle (no zombie).
+ *
+ * Round 9 family V (campaign note log-20260905t165205z-69e4be06) NARROWS the
+ * rule: the pair's strategy.close is a CLOSE-TIME act, issued after the bar's
+ * intrabar broker events, so the dormancy it imposes must not feed that same
+ * bar's forced-liquidation pass. 2b5e8e7 held the bracket dormant inside the
+ * script body and the end-of-bar process_margin_call revived it at the
+ * extreme — the round-8 candidate-i regressions on ETH/EURUSD/XAUUSD@15
+ * (rhyme17 ETH 2025-04-07 13:45Z: TV "Margin call" 2.294 @1557.76 then
+ * "Long" 4.662 @1549.51 at the 14:00Z open; the engine closed the 4.662
+ * "Short Exit" @1557.76). lab tv tapes scratchpad/famV/pins (ws-report-v1,
+ * rangeProof covered):
+ *   F. BINANCE:ETHUSDT.P 15, 2025-04-01..04-20, the 13:45Z bar
+ *      (O 1493.53 H 1557.76 L 1489 C 1549.52), 100% short at the 13:30Z
+ *      close, filled at the 13:45Z open:
+ *      F1 famV-eth-pair-mcbar-reissue (stop avg+30 re-issued every bar; the
+ *         pair Long + close("Short") at the 13:45Z close) and F2 -once (the
+ *         stop issued once, with the pair): "Margin call" 2.208 @1557.76
+ *         THEN "Long" 4.4875 @1549.51 at the 14:00Z open, then the long
+ *         6.1999 closed by close_all at the 14:30Z open 1557.92 (csv
+ *         33cb2aac). The close-time bracket does NOT fill at the extreme.
+ *      F3 -norev (no pair): the same slice, then "Short Exit" 4.4875
+ *         @1549.51 at the 14:00Z open — a bracket born at the close with a
+ *         breached level fills at the next open (632e3afe).
+ *      F4 -prevbar-admitted (short at the 13:00Z close, resting stop 1530
+ *         from the 13:15Z close, the pair at the 13:30Z close, ADMITTED at
+ *         the 13:45Z open 1493.53): 0.0708 @1515.35 "Margin call" on the
+ *         entry bar, "Long" 6.5372 @1493.53, the purged stop never acts,
+ *         the long 6.7819 rides to the 14:30Z open 1557.92 (583a6b81).
+ *   G. OANDA:XAUUSD 1D, 2025-06-01..08-01, margin_short=50 — the 100% short
+ *      (3 lots @3322.825) has headroom, so NO cascade anywhere:
+ *      G1 famV-xau1d-noMC-rev (the pair at the 07-10 close, DECLINED at the
+ *         07-13 open — no Long row): the resting stop 3370.325 does NOT
+ *         fill on the 07-13 bar although H 3375.085 crosses it; the re-issue
+ *         fills 07-15 21:00Z @3370.325 x3 (a82f6b99) — finding-311's kill on
+ *         a bar with no revive, TV-pinned (E1's shape).
+ *      G2 -norev: the stop fills on the 07-13 bar @3370.325 x3 (2886cc24).

+ * test_dual_entry_placement_sizing.cpp — KI-65: dual same-bar opposite
+ * strategy.entry from FLAT with placement-time sizing + pending-market
+ * awareness.
+ *
+ * PIN (data/progress/probe-matrix-adjudication-20260711.md §KI-65, probe
+ * data/probes/pf-probe-ki65-dual-entry-precedence, 7,429 TV trades):
+ * from flat, pyramiding=0, POOC=false, explicit fixed qty — TV runs NO
+ * arbitration on two opposite same-bar strategy.entry calls; BOTH execute.
+ * Sizing freezes at PLACEMENT with pending-market awareness: the SECOND call
+ * sells its own qty PLUS the qty of the pending same-bar OPPOSITE MARKET
+ * entry (a pending STOP contributes 0; a placement-REJECTED entry contributes
+ * 0). Net: the second (priced) leg FULLY REVERSES the position the first
+ * (market) leg opens — it does NOT collapse to close-only-flat.
+ *
+ * MECHANISM (engine): a flat-armed priced (stop/limit) entry that reverses a
+ * position opened THIS bar by an EARLIER opposite-direction MARKET entry took
+ * the M2a close_only_opposite gate (apply_entry_order_fill →
+ * close_opposite_then_enter): it closed the market leg and stayed FLAT,
+ * dropping the second leg. TV holds the second leg. The fix scopes the gate
+ * OUT of these market-first cells via a placement-time flag
+ * (reverses_same_bar_market_from_flat) so the fill takes the ordinary
+ * full-reversal path (flip_market_position_to, close_only=false).
+ *
+ * R1/R2/R3 are the priced-second-leg KI-65 cases. G1/G3 pin the STOP-first and
+ * placement-rejected controls. The MARKET/MARKET follow-up cases below pin the
+ * remaining broker contract: gross placement admission, buy-before-sell fill
+ * priority, and transaction-net execution for an admitted pair.
+ *
+ * Cell map (probe hours, TRUE combo under the probe's v6 float-div coverage):
+ *   MS-LF-A (hh=04, 391 ev): E1 long MARKET, E2 short STOP → TV: long dur0,
+ *                            short HELD.  Engine HEAD: close-only-flat.  [R1]
+ *   MS-SF-A (hh=06/10, 782): E1 short MARKET, E2 long STOP → TV: net +1 long
+ *                            HELD.  Engine HEAD: close-only-flat.        [R2]
+ *   SS-LF-A (hh=08, 391 ev): E1 long STOP, E2 short STOP → single close,
+ *                            net FLAT (BOTH match — must stay).          [G1]
+ *   MM-*-A  (hh=00/02):      both MARKET, net can match through wrong rows. [G2]
+ *   -U cells / placement-reject: E1 over-notional → dropped, contributes 0. [G3]
+ * Out of scope (frozen characterization): SS-SF (never ran in the probe),
+ * pyramiding>0 multi-bar pyramids, deferred_flip carry (own suite).

+/*
+ * test_exit_bracket_position_cycle_lifetime.cpp — finding-347. A from_entry
+ * bracket leg lives for the POSITION cycle, not for its own entry bucket.
+ *
+ * Bug (pre-fix): classify_order_eligibility tested pyramid_entries_ RESIDENCY
+ * to decide whether a from_entry-bound exit was still live. When a sibling
+ * bracket FIFO-consumed all of a leg's own units, no pyramid entry carried that
+ * entry_id any more and the next eligibility pass Removed the leg permanently.
+ * The engine then fired 3 of 4 bracket legs, carried a phantom unit and never
+ * reached flat.
+ *
+ * TV's rule: from_entry decides only whether a leg is ALLOWED TO EXIST (its
+ * parent entry must have filled in this position cycle), never which units it
+ * may take — those come from the position-level FIFO queue. The engine's FILL
+ * path already drew FIFO across buckets; only the eligibility gate was
+ * bucket-scoped, which is what makes the fix surgical.
+ *
+ * Ground truth — thulashimohanr-prev-day-week-levels-or-vwap-strategy,
+ * ETH-USDT-USDT 15m (UTC). 2025-06-17 09:45 fills BOTH entry ids on one bar
+ * (`Short` 2u + `ShortAdd` 2u = 4 units, 4 bracket legs priced off the same
+ * 09:30 close). TV's CROSS-ASSIGNED exit labels are the direct proof:
+ *
+ *   #127 06-17 14:45  T1 Exit   2525.91 q1   entry ▼ SHORT     (Short's leg,    Short unit)
+ *   #128 06-17 14:45  Add T1    2525.91 q1   entry ▼ SHORT     <- ShortAdd's leg took a Short unit
+ *   #129 06-17 16:45  T2 Exit   2465.91 q1   entry ▼+ ADD      <- Short's leg took a ShortAdd unit
+ *   #130 06-17 16:45  Add T2    2465.91 q1   entry ▼+ ADD
+ *                                            ==> 4 in, 4 out: TV is FLAT 16:45
+ *
+ * The T1 pair drains BOTH `Short` units (engine agrees), orphaning `ShortT2`.
+ * TV still fires it at 16:45; the engine Removed it and fired only `ShortAddT2`
+ * — one unit instead of two. Identical at 2025-10-14 and 2026-01-14. Exactly 3
+ * of the window's 12 two-id bars diverge: the 9 that exit all four legs on ONE
+ * bar match, because no eligibility pass runs inside the orphaning window.
+ *
+ * Fix: replace bucket residency with position-cycle provenance
+ * (cycle_filled_entry_ids_, cleared on flat / fresh open).
+ *
+ *   A. the 06-17 shape — all FOUR units exit, 2 at the T1 price and 2 at the
+ *      T2 price, including the ORPHANED bucket's leg; engine flat afterwards.
+ *      (RED pre-fix: 3 rows, 1 phantom unit left open.)
+ *   B. the 06-18 shape — because A now reaches flat, the next day's same-id
+ *      entry is ADMITTED. This is the p1 (monotone pyramiding counter)
+ *      interaction pin: p1 asks the right question, and only D3 gives it the
+ *      right position to ask it about.
+ *   C. negative — a leg whose from_entry NEVER filled in this cycle is still
+ *      Removed (the gate still has teeth).
+ *   D. the Remove path's original purpose survives: after a full close, a
+ *      stale leg from the prior cycle does not fire against the new position.

+ * test_exit_id_scoped_erase.cpp — strategy.exit's replace-erase must be
+ * scoped to the matching prior EXIT order, never a pending entry.
+ *
+ * Pine v6 contract: entry-order ids and exit-order ids live in
+ * INDEPENDENT namespaces. A ``strategy.exit(id=X, from_entry=Y)`` call
+ * replaces only a prior pending EXIT order with the same (id, from_entry).
+ * It must NOT delete:
+ *   (a) a same-bar pending ``strategy.entry(id=X)`` that reuses the id
+ *       string — otherwise the position never opens (zero trades);
+ *   (c) a sibling exit ``(id=X, from_entry=other)`` bound to a different
+ *       entry.
+ * And it MUST still:
+ *   (b) replace a prior exit with the same (id, from_entry).
+ *
+ * Regression for the bare ``o.id == id`` erase predicate in
+ * clear_existing_exit_order (engine_strategy_commands.cpp), which deleted
+ * the still-pending entry when a script reused one id for both
+ * strategy.entry and strategy.exit on the same bar.

+/*
+ * test_explicit_qty_fill_admission.cpp — TradingView's fill-time DECLINE of an
+ * EXPLICIT-qty (caller passed a finite qty) true-flat MARKET entry whose
+ * next-bar fill gaps adversely enough that the position notional at the SLIPPED
+ * FILL price overshoots the placement-time equity snapshot.
+ *
+ * Rule (design-explicit-qty-fill-admission, GO — probe-68 pinned): a pending
+ * MARKET entry from strategy.entry with a FINITE explicit qty, created TRUE-FLAT
+ * (created_position_side==FLAT && !created_after_position_close_in_bar) and still
+ * FLAT at fill, is silently DROPPED (no trade row) at fill when
+ *
+ *   |qty| * slipped_fill * pv * fx * (margin_pct/100)
+ *     >  max(placement_equity, |qty| * slipped_signal_close * pv * fx * margin/100)
+ *        + max(1e-9, |placement_equity| * 1e-12)
+ *
+ * with margin_pct > 0 and ZERO structural slack (float guard only — probe-68
+ * kills the one-lot term). The slipped-signal-close notional floors the
+ * threshold so a fill AT/BELOW the slipped signal close (POOC, or a no-gap /
+ * favorable open) is a structural no-op even with slippage != 0; only an ADVERSE
+ * gap beyond the slip can decline. Commission is EXCLUDED from the predicate.
+ *
+ * This is the EXPLICIT-QTY sibling of the shipped frozen-omitted-qty gap-reject
+ * (test_frozen_flat_gap_reject.cpp); that fix deliberately left this path alone.
+ * The signal-time gate in strategy_entry (~:139-158) stays the first line of
+ * defense; this is the fill-time re-check.
+ *
+ * Evidence anchors: data/probes/pf-probe-allin-floor-comm0 (4,740 from-flat
+ * attempts, decline iff fill notional > equity, zero slack, 99.94%);
+ * mdfe3757-trade-strategy-v8-4-pine-v6-ready (306/306 separation).
+ *
+ * RED-1  flat explicit all-in, comm 0, fill +1 mintick above signal -> DECLINED.
+ * RED-2  same WITH commission > 0 -> STILL DECLINED (commission not in predicate).
+ * GREEN-A favorable slip (fill below close), zero-headroom  -> ADMITS full qty.
+ * GREEN-B exact tie (fill == close, no slippage)            -> ADMITS.
+ * GREEN-C headroom (qty at 50% equity) + big adverse gap    -> ADMITS.
+ * GREEN-D commissioned all-in favorable-slip                -> ADMITS (fill happens).
+ * GREEN-E margin>100 characterization + margin==0 inertness.
+ * GREEN-F priced (stop=) entry adverse gap + RAW strategy.order -> unaffected.
+ * GREEN-G POOC=true with slippage>0                         -> no spurious decline.
+ * H       same-bar close-then-explicit-reentry (after-close), adverse gap ->
+ *         DECLINED (re-pinned 2026-09-03 under design-market-entry-
+ *         affordability: the rule has no after-close carve-out).
+ * GREEN-I strategy.exit bracket bound to a declined entry   -> inert, no crash.

+ * test_famae_declined_reversal_trail_gap.cpp — round 10 family AE
+ * (stevenygabbyperez-fast-scalper-with-stops on NASDAQ:AAPL@15): what a
+ * declined reversal does to the position's TRAIL leg when the decline bar
+ * itself reaches the trail's activation.
+ *
+ * Round 9 family X pinned that the kill is leg-scoped: the stop and limit
+ * legs die, the trail leg lives from the bar after the decline. Its engine
+ * armed that revived leg from the position's running extreme INCLUDING the
+ * decline bar, so a decline on a bar whose range crossed the activation fired
+ * the trail at the next open. TradingView does not:
+ *
+ *   NASDAQ:AAPL 15m, long signal 2025-10-30 15:00Z (fill 15:15Z @270.90),
+ *   short signal 19:45Z = an all-in reversal declined at the 10-31 13:30Z
+ *   earnings-gap open 276.90 (bar H 277.32 L 269.15 C 270.68; the reversal
+ *   costs 2 % more than the account holds). `lab tv` tapes (campaign note
+ *   log-20260905t224809z, window 10-27..12-06):
+ *
+ *     famae-dr-ctrl        no reversal, the probe's exit (activation
+ *                          270.90 + 2 % = 276.32): 'Exit Long' 13:30Z @276.90
+ *                          — the open gaps past the activation, fill at the open
+ *     famae-dr-probe       with the declined reversal: NO exit at 13:30Z or
+ *                          13:45Z, none on 11-13 14:30Z when 276.32 is crossed
+ *                          again (high 276.69) — the leg is DEAD; the long rides
+ *                          to the range end
+ *     famae-dr2-tp610-ctrl activation 277.00 (open 276.90 below it, high past
+ *                          it): 'Exit Long' 13:30Z @277.00, the one-shot fill
+ *     famae-dr2-tp610      with the reversal: no fill at 13:45Z (a 277.32 best
+ *                          would have gap-filled the 270.72 open) — the leg
+ *                          resumes UNARMED; TradingView arms it at the 11-24
+ *                          20:45Z touch (high 277.00) and fills 11-25 14:30Z
+ *                          @280.38 riding that bar's extreme
+ *     famae-dr2-tp700      activation 277.90, never reached on the decline
+ *                          bar: the leg lives and fills one-shot at the level
+ *                          when 11-25 14:30Z crosses it, @277.90 (family X)
+ *     famae-dr-stop2695    stop 269.50 (crossed by the decline bar's low and
+ *                          14:00Z): dead after the decline (family X); ctrl
+ *                          fills 13:30Z @269.50
+ *
+ * Rules (engine.hpp PendingOrder::dormant_trail_best /
+ * dormant_trail_leg_dead): the surviving trail leg's running extreme skips the
+ * decline bar (seeded with the position's best before it); a trail leg whose
+ * activation the decline bar's OPEN already sits past dies with the stop and
+ * limit legs.
+ *
+ * Documented residual, outside this family: TradingView's touch at 11-24
+ * 20:45Z (high == activation 277.00) ARMS the offset-less trail without
+ * filling it and the next bar fills at its extreme (280.38); the engine's
+ * activation test fills the touch one-shot at the level (11-24 20:45Z
+ * @277.00). The tp610 case therefore asserts only what this family owns: no
+ * fill on the revival bar, a fill no earlier than the 11-24 20:45Z bar.
+ *
+ * Registry feed bars via `lab bars` (the bars between 10-31 18:00Z and the
+ * three later windows never reach 276.32 / 277.00 / 277.90 — first touches
+ * 11-13 14:30Z / 11-24 20:45Z / 11-25 14:30Z — so the reduced table keeps
+ * every activation event of the tapes).

+ * test_famag_close_survives.cpp — a strategy.close co-queued with a default
+ * all-in reversal SURVIVES a rule-5 whole drop (round 11 family AG; campaign
+ * notes log-20260905t232805z-41661c90 and log-20260905t233556z-7f5ce2ed).
+ *
+ * The scrapper wrapper's reversal idiom is strategy.entry(opposite) THEN
+ * strategy.close(current) on one signal bar. When TradingView's price-scale
+ * margin check (engine.hpp rule 5: P = sig10(sig10(E_s) / Q) < tick(close_S))
+ * drops the reversal, the reversal order is gone at placement and the
+ * co-queued strategy.close still fills at the next open — the position goes
+ * flat, no new position, the tape prints 'Close entry(s) order <id>'. Only the
+ * fill-open gap reject (KI-54, Q x open > E_s) is atomic with its co-queued
+ * close: TradingView holds the position and the close never fires (#91,
+ * suppress_declined_reversal_close_legs). Rule 2 (E_s < sig10(cost)) keeps
+ * the reversal's own close leg, whose row carries the reversal's id.
+ *

+ * Round 12 AG-C2: rounded required money at an existing 1x opening check.
+ *
+ * TradingView pins: r12-c2-may28, r12-c2-jun09 and the repaired June 9
+ * near1/near2/headroom-seedearly sensors. See campaign notes
+ * log-20260906t030608z-5e7dd07e and log-20260906t030919z-9a77d540.
+ * Small synthetic fixtures retain the pins' signal/fill prices and
+ * capital constants, without loading a corpus, feed, or verifier.
+ *
+ * May 28: TV trims 62.32 at the long fill, not the exact-cost 62.28.
+ * June 9: rounded required money exceeds exact equity by 0.000148, so TV
+ * trims one contract at the short fill, then 1912.92 at the adverse high.
+ * Moving the old quantity to newQ-0.01/-0.02 keeps both events. Adding
+ * 0.0006 equity removes only the opening call, giving 1916.92 at the high.
+ * r12-c2-may28-pricedexit independently pins the same 62.32 opening trim
+ * before a pending stop at 1.13430, which closes 885063.82 on that bar
+ * (TV CSV a1a4872e7f5ff6bbebf538f1186bf8d4902ef3566e1f0d6ee195982dc510a496).

+ * test_fills_edge.cpp — edge-arm coverage for src/engine_fills.cpp's
+ * bar-pump fill loop (process_pending_orders + helpers). Engine-behaviour
+ * tests: each subclasses BacktestEngine, drives strategy.* commands inside
+ * on_bar, and asserts the resulting CLOSED-TRADE exit prices / counts.
+ *
+ * Targets (uncovered arms in engine_fills.cpp):
+ *   - gap-at-open priced entry/exit -> fill at bar.open (the std::max/std::min
+ *     gap shortcut in evaluate_fill_price + the fill-phase 0 classification
+ *     in sort_orders_by_fill_phase, including the SHORT exit-style arms
+ *     lines 192-194 and the SHORT entry-limit arm lines 929-934).
+ *   - same-bar competing sibling exits resolved by the path-fill comparator
+ *     in sort_exit_siblings_by_path_fill (full-before-partial / earliest-
+ *     touch arms, lines 132-167).
+ *   - intraday max-filled-orders cap that latches then resets on the next
+ *     chart-day, with the cap auto-close price taken at the bar extreme
+ *     (bar.high for a long stop-entry that fired intra-bar; lines 350-360,
+ *     481-485).
+ *   - percent-based partial exit by entry (execute_partial_exit_by_entry_percent,
+ *     reached via close_entries_rule_any_ + from_entry, lines 583-591).
+ *   - high-level strategy.exit actionability: calls whose limit, stop,
+ *     profit, loss, trail_points, and trail_price are all runtime NaN are
+ *     inert after cancelling a matching prior bracket; strategy.close remains
+ *     the market-close API.
+ *
+ * NDEBUG-PROOF: every assertion uses the returning CHECK macro (failure
+ * increments g_fail; main returns nonzero). bare assert() is never used, so
+ * the canonical Release/-DNDEBUG gate cannot make these pass vacuously.
+ * Non-vacuity was confirmed by temporarily corrupting one expected value
+ * and observing a FAIL + nonzero exit, then restoring it.

+ * test_frozen_flat_gap_reject.cpp — TradingView's fill-time REJECTION of a
+ * frozen 100%-of-equity true-flat MARKET entry whose gapped fill price pushes
+ * the frozen-quantity notional past the sizing equity at all.
+ *
+ * Rule (design-cntvxiao-gap-reject, PANEL-CLEARED; widened to commissioned
+ * entries by the round-7 market-entry-admission pin): a pending MARKET entry
+ * created by high-level strategy.entry with omitted qty (frozen default sizing,
+ * percent_of_equity == 100%), direction-appropriate margin == 100, placed
+ * TRUE-FLAT (created flat, not a same-bar paired close/reentry) and still FLAT
+ * at fill, is silently dropped (no trade row) at fill when:
+ *
+ *   |frozen_default_qty| * slipped_fill * pv * fx * margin/100
+ *     >  sizing_equity
+ *        + max(1e-9, |sizing_equity| * 1e-12)
+ *
+ * Direction-symmetric (long AND short). ANY positive shortfall rejects — there
+ * is NO one-lot amnesty and the opening commission is NOT part of the test
+ * (campaign notes log-20260905t071818z-e57e7235 / log-20260905t071819z-
+ * ece9b623, lab tv tapes scratchpad/r7/pins/macd1d-mktadmit-*: 0.1%
+ * commission, 206 placements, 0 violations; replayed on the registry bars by
+ * test_market_admission_commission). pct<100 or gap-DOWN entries are
+ * untouched, and a commissioned entry whose cost fits but whose cost + fee
+ * does not keeps the KI-61 fill-then-trim path. See the gate in
+ * engine_fills.cpp apply_filled_order_to_state for the evidence trail.
+ *
+ * RED-4  SHORT true-flat zero-comm above-lot gap  -> rejected (FLAT, no rows).
+ * RED-6  rejected SHORT emits NO rows AT ALL, incl. the entry-bar margin-call
+ *        trim rows the pre-fix engine produced.
+ * RED-5  sub-lot positive-shortfall gap-up (qty_step>0) -> rejected (FLAT,
+ *        no rows).
+ * GREEN-B strategy.exit bracket bound to a flat-dropped entry id is inert
+ *        (no phantom exit fill, no crash).
+ * RED-7  commissioned twin of RED-6 (10% fee, 9 x 120 = 1080 > 1000): rejected
+ *        (FLAT, no rows) — re-pinned by the round-7 tapes; it used to fill
+ *        and take a 4-lot Margin-call trim.
+ * GREEN-C commissioned fee-only shortfall (9 x 110 = 990 <= 1000 < 990 + 99):
+ *        fills then takes the KI-61 one-lot Margin-call trim.
+ * GREEN-D pct=99 twin: fills (rule requires EXACTLY 100).
+ * GREEN-E gap-DOWN true-flat: fills with the frozen qty.

+ * test_full_close_while_pyramiding.cpp — regression for a full-position
+ * take-profit exit (strategy.exit with qty_percent=100, no explicit qty)
+ * RE-ISSUED every bar while the position is still GROWING via pyramiding/DCA.
+ *
+ * Bug (pre-fix): compute_exit_reserved_qty honoured the preserved (frozen)
+ * reserved qty captured by clear_existing_exit_order on re-issue even for a
+ * 100% exit. So the reserved qty stayed pinned at the size from the bar the
+ * exit was first placed, instead of re-expanding to 100% of the now-larger
+ * position. At the TP touch the engine closed only the first FIFO lot at the
+ * true TP price; the residual lots exited one bar late at a re-priced limit /
+ * next-bar-open. One logical exit fragmented across two bars → wrong exit
+ * prices + inflated trade count + inflated PnL.
+ *
+ * Fix: gate the preserved-qty carry to genuine PARTIAL re-issues only
+ * (qp < 100 - kFullPercentEps). A re-issued full exit falls through to
+ * recompute requested = position_qty * qp/100 = full grown position; since
+ * clear_existing_exit_order already removed the prior order, available == full
+ * current position → reserves 100% → closes the whole stack at the single TP
+ * touch.
+ *
+ * Minimal repro (matches the TradingView-verified expectation):
+ *   pyramiding=5; three entries qty=10 @100 (avg 100); every bar
+ *   strategy.exit("TP", limit=avg*1.04) (TP=104); trigger bar
+ *   O=101 H=110 L=100 C=108.
+ *   EXPECTED (TV): all 30 units close @104 on the trigger bar, PnL=120.
+ *   BUG:           lot#1 @104, lots#2-3 one bar late @108, PnL=200.

+// test_intraday_cap_auto_close.cpp — pin down TV's
+// ``strategy.risk.max_intraday_filled_orders(N)`` semantics:
+//
+//   1. The Nth fill on a chart-day is allowed AND immediately followed by
+//      a synthetic full close at the same fill_price tagged
+//      "Close Position (Max number of filled orders in one day)".
+//   2. After that auto-close, every subsequent fill on the same chart-day
+//      is silently rejected (LATCH-TILL-DAY-ROLLOVER).
+//   3. The first fill of the next chart-day is accepted (latch + counter
+//      reset on day rollover).
+//   4. The synthetic close exits at the entry's fill price -> per-pyramid
+//      PnL is zero before commission (here commission=0, so trade.pnl=0).
+//
+// Why this is the high-signal test path: TV emits ~one cap-close per
+// chart-day where the cap fires, NOT multiple per day (probe 97b: 382
+// cap-closes across 13 months of data). A prior fix that recharged the
+// counter after each cap-cycle over-fired cap-closes and produced 3459
+// engine vs 1957 TV trades on probe 97b (43% over-count). The latch
+// pinned here matches TV's true semantics.
+//
+// The fixture uses 15m bars so the cap counter and the chart-day rollover
+// are both exercised within a small bar count. Fills are driven by raw
+// ``strategy_entry`` calls inside ``on_bar`` rather than crossover signals
+// so the test pins the engine's cap-state machine, not indicator math.

+ * test_limit_exact_touch_level_residue.cpp — issue #177 (dfl3xrs, 2026-09-04):
+ * a strategy.exit(limit=) target that the bar's extreme reaches EXACTLY is
+ * filled by TradingView on that bar; the engine filled it bars later at the
+ * same price whenever the level carried a floating-point residue.
+ *
+ * TradingView rule (round 8 family T, pinned 2026-09-05 by 40 lab tv sensor
+ * tapes on NYSE:F / CME_MINI:ES1! / OANDA:EURUSD 15m, scratchpad famT/pins):
+ * a resting stop/limit LEVEL within 0.01 / pricescale^2 of a price-grid
+ * value (k / pricescale) is stored AS that grid value and tested against
+ * the tick-quantized bar (round 6 stop-tick-rounding). A level computed as
+ * `avg_price + r` (2683.8 + (2683.8 - 2682.7) = 2684.9000000000005) is
+ * therefore 2684.9 to TradingView and fills on the bar whose high is
+ * 2684.9. The engine compared the RAW level with the quantized bar, so the
+ * +4.5e-13 residue skipped the touch bar. The reporter's reading — a strict
+ * `>` where TV uses `>=` — is not the mechanism: an exact literal level
+ * fills on the touch bar on main (the compare is already inclusive); only
+ * a residue-laden level misses.
+ *
+ * The bar is the reporter's first case verbatim (MGC 1-minute, mintick 0.1,
+ * 2025-01-14 12:22 UTC: O 2683.9 H 2684.9 L 2683.7 C 2684.8, limit 2684.90,
+ * TV filled 12:22 @2684.90; PineForge exited later). The short case mirrors
+ * the fourth (buy limit 2038.20 on a bar whose low is 2038.2).
+ *
+ * The fix in flight is the order-level price-grid snap on round8/famT
+ * (level_on_price_grid at strategy.entry/exit/order storage); this test is
+ * the reporter's shape as a regression check for it.
+ *
+ * NDEBUG-PROOF: every assertion uses the returning CHECK macro.

+/*
+ * test_m_admission_36.cpp — round 7 family M, mechanisms 3 and 6: the
+ * short-side entry-price affordability trim and the stop-entry reversal
+ * admission equity.
+ *
+ * Sources: campaign notes "round 7 family M mechanism 3/7" (market-logic-
+ * india low-lag-strength-oscillator OANDA:XAUUSD@1D, moderate 100 count 2)
+ * and "mechanism 6/7" (jaysharmaofficial alphamojo supertrend HA-with-buffer
+ * BINANCE:BTCUSDT@1D, weak 75 count 1), 2026-09-05 11:16Z; the family-G pin
+ * (reversal sizing marks at tick(close): "a positive fill-time shortfall
+ * becomes the 1-lot entry-bar 'Margin call' trim at the entry price, PnL
+ * 0"), the family-H pin (market-entry admission: the fee-only shortfall is
+ * filled and trimmed at the fill), the family-E pin (stop-entry admission:
+ * "a still-open opposite position costs nothing"; fill check at the level
+ * against equity at fill) and the family-L rule (entry-bar margin call over
+ * the post-fill OHLC path). The two probe tapes are replayed row-for-row on
+ * the registry's own 1D bars (test_m_admission_36_data.hpp).
+ *
+ * Rule 3 (mechanism 3): a default-sized percent_of_equity 100 SHORT opened
+ * by a MARKET order at 100% margin takes the same fill checkpoint as the
+ * long side, with or without a commission — when its fill cost exceeds the
+ * equity the fill left (the closing leg of a close-then-short realized at
+ * the open), TradingView books the floor-before-4x trim (sub-lot shortfall:
+ * ONE lot) AT THE FILL PRICE, PnL 0, tagged "Margin call", and only then
+ * marks the survivor over the post-fill path. market-logic 2025-12-04
+ * 06:00 (bar 12-03 22:00Z, open 4206.465): E_s = 8983.64 + 1.2 x (4203.115
+ * - 4088.255) = 9121.47 -> Q = 2.17; cost 2.17 x 4206.465 = 9128.03 against
+ * 9125.49 realized -> TV 22 "Margin call" 1.0 @4206.465 (PnL 0), TV 23 =
+ * 1.17 carried to 12-11. The engine's short event was scoped to commissioned
+ * shapes only, so the whole 2.17 rode into the ordinary cascade (0.04
+ * @4219.62 + 0.04 @4259.34, EN 22-24) and every later quantity drifted with
+ * the equity (EN 27/28 reversal 01-05 where TV drops it, EN 29-34 re-short
+ * 01-08 vs TV 30 held to 03-09). The long side's trims (TV 7 09-22, TV 20
+ * 11-20: 1.0 @ the entry price, PnL 0) are the control and stay as they are.
+ *
+ * Rule 6 (mechanism 6): the fill-time admission of a STOP entry that
+ * REVERSES a position costs qty x tick(fill) against realized equity PLUS
+ * the open position marked at the fill it closes at (the family-G sizing
+ * equity) — the closing leg is free and is realized at this very fill.
+ * jaysharma 2025-08-26 (bar 08-26 00:00Z, L 108666.66): the fixed 1 BTC
+ * sell stop at haLow x 0.9995 = 109219.46 is admitted against 100000 +
+ * 13972.86 (the 04-27 long 95246.60 closed at the level) = 113972.86 (TV 1
+ * exit / TV 2-6 entry), then margin-called as BTC rises (0.05516 @112371 on
+ * the entry bar's post-fill high, 0.043 @115488.09, 0.0212 @117900, 0.1198
+ * @121022.07) and closed by the 10-02 flip's buy stop 121082.59 (TV 6) —
+ * whose opening leg TV never fills: 1 x 120529.35 > 102905.5 + (109219.46
+ * - 120529.35) x 0.76084 at the 10-02 close, the family-E placement check,
+ * so only the closing leg rests (affordability_close_only). The engine's
+ * realized-only basis (100000 < 109219.46) declined the 08-26 reversal and
+ * held the long to 01-30 (3 trades vs 8). Flat fills are unchanged (no open
+ * position); same-direction adds keep the realized-only basis (unpinned).
+ *
+ *   A. market-logic XAUUSD@1D: 33 TV rows row-for-row; the 12-04 trim and
+ *      carry by name; the long trims (TV 7, TV 20) unchanged; the pinned
+ *      01-04 dropped reversal (no fill 01-05, short held to 03-09).
+ *   B. jaysharma BTCUSDT@1D: 8 TV rows row-for-row; the 08-26 reversal by
+ *      name; the 10-03 close-only leg (no long opened); the range-end row.
+ *   C. Controls (synthetic, mintick 0.01, 1-share lots):
+ *      C1 a stop reversal whose cost exceeds realized + open PnL at the
+ *         fill is still DECLINED although realized alone would admit it;
+ *      C2 the mirror (jaysharma in miniature): realized alone declines,
+ *         realized + the closing leg's profit admits;
+ *      C3 a FLAT stop entry is byte-identical (admitted at cost == equity,
+ *         declined one cent over);
+ *      C4 a zero-commission TRUE-FLAT default short: the gap-reject drops
+ *         an over-equity fill and an exact-cost fill carries no PnL-0 trim
+ *         (the ordinary cascade only).

+// test_magnifier_real_bars.cpp — verifies the real-bar magnifier mode
+// activates whenever multiple input sub-bars per script bar are fed into
+// run_magnified_bar (i.e. input_tf < script_tf), and that the resulting
+// fill timing reflects the actual lower-TF bar where the level was crossed
+// rather than a synthesized intra-script-bar tick.
+//
+// Background: prior to the real-bar magnifier mode, the engine sampled
+// magnifier_samples_ ticks along each sub-bar's OHLC path using whatever
+// MagnifierDistribution the user configured. With non-ENDPOINTS distributions
+// (UNIFORM/COSINE/etc.) the synthesized intra-1m mid-points injected ticks
+// that don't correspond to any real lower-TF data — adding ~0.2% drift to
+// exit prices. This file pins the new contract: when sub_bars come from a
+// real lower-TF feed, every distribution collapses to ENDPOINTS+4 (the four
+// real OHLC turning points of each lower-TF bar) so fills land exactly on
+// the lower-TF bar where price actually crossed the level.

+ * test_margin_call_gap_open.cpp — finding-430: forced liquidation at the
+ * bar OPEN when a carried leveraged position already breaches the margin
+ * requirement there (TradingView's broker emulator checks margin at every
+ * point of the intrabar path, and the open is the first one).
+ *
+ *   A. Gap-open breach, no further breach at the extreme: exactly ONE
+ *      "Margin call" row, filled AT THE OPEN, with the quantity computed at
+ *      the open price (4x the open-priced shortfall).
+ *   B. Gap-open breach AND a deeper breach at the adverse extreme: TWO
+ *      "Margin call" rows on the same bar — the open slice first, then the
+ *      survivor's extreme slice with the quantity computed at the extreme
+ *      on the post-slice position.
+ *   C. No open breach (open below the liquidation price, high above it):
+ *      the established single adverse-extreme slice, bit-identical to the
+ *      pre-fix engine (regression guard for on-tick feeds without gaps).
+ *   D. Whole-share lot grid (qty_step = 1, the NASDAQ:AAPL tape shape):
+ *      floor-before-4x at the open price and the one-contract fallback when
+ *      the open-priced shortfall floors to zero.
+ *   E. A leveraged LONG gapping DOWN through its liquidation price is
+ *      sliced at the open on the same terms.
+ *   F. The emulator switch (set_margin_call_enabled(false)) disables the
+ *      open slice together with the rest of the forced-liquidation family.

+/*
+ * test_margin_call_intrabar_chronology.cpp — finding-308: TV places the
+ * forced-liquidation event chronologically on the synthesized intrabar path.
+ *
+ * When a priced exit of the live position fills on a bar whose adverse
+ * extreme comes STRICTLY earlier on the engine's own OHLC path
+ * (bar_path_uses_high_first proximity rule) than the exit's fill, and the
+ * pre-fill position is already in margin deficit at that extreme, TV slices
+ * FIRST (floor-before-4x nibble, filled at the extreme, "Margin call" tag)
+ * and the exit then closes the reduced remainder. Previously the engine
+ * checked margin once AFTER all order processing, so a same-bar full exit
+ * hid the deficit (FLAT early-return) and the event was lost.
+ *
+ * The fixtures reproduce the rhyme17 derivation's 2025-10-11 20:45 seed
+ * arithmetic exactly (short 2.5105, adverse high 3721.62, deficit ~8.15,
+ * q_min 0.0021894... -> floor 0.0021 -> 4x = 0.0084):
+ *
+ *   A. HIGH-first bar, TP limit fills after the high -> slice 0.0084@high,
+ *      TP closes the remainder 2.5021. (The confirmed gap event.)
+ *   B. LOW-first bar with the SAME large deficit at the high -> the exit
+ *      fills before the extreme on the path -> NO margin call. (The two
+ *      tape bars 2025-06-28 08:15 / 2025-09-17 18:45 that a naive
+ *      check-before-orders would false-fire.)
+ *   C. TIE — the exit stop fills exactly AT the adverse extreme -> exit
+ *      first, NO margin call. (Protects the 157/158 quiet SL-stop bars.)
+ *   D. SL stop strictly BEFORE the extreme -> quiet (same protection).
+ *   E. Partial exit variant: exactly ONE margin-call slice on the bar (the
+ *      end-of-bar cascade is consumed by the chronological slice; the
+ *      survivor is re-checked from the next bar on).
+ *   F. Emulator off -> nothing fires.
+ *   G. Handle reuse: a rerun reproduces the same rows (bar-keyed one-shot
+ *      markers reset with reset_run_state).

+ * test_margin_call_trail_exit_chronology.cpp — finding-308 extended to TRAIL
+ * exits.
+ *
+ * The chronological pre-exit forced-liquidation slice was gated on
+ * `exit_path_fill = !exit_fill.is_trail`: a TRAIL fill was excluded because
+ * the hook derived the exit's chronology from first_touch_position(fill
+ * price), and a trail's fill price is not a resting level — its first path
+ * touch is not necessarily its fill moment (the trail must arm first). The
+ * exclusion failed closed and dropped every margin-call slice on a bar whose
+ * adverse extreme precedes a trailing exit.
+ *
+ * resolve_exit_path_fill now reports the fill's ACTUAL path position, so the
+ * chronology is exact for every intrabar path fill and the trail leg no
+ * longer needs excluding.
+ *
+ * Exemplar (boztilkiserhan serhan1 WMA/RSI trailing scalp, ETHUSDT.P 15m,
+ * 2025-10-19 08:15 UTC — bar O 3886.31 / H 3960 / L 3810 / C 3873.57, short
+ * 2.119 @ 3879.36 carried in):
+ *
+ *   TV     — Margin call 0.234 @ 3960 (the adverse high), then "Exit Short"
+ *            closes the remaining 1.885 @ 3821.06 on the H->L leg.
+ *   Engine — one row: the whole 2.119 @ 3821.06, no margin call.
+ *
+ * Fixtures:
+ *   A. HIGH-first bar, trail fills after the high -> slice 0.234 @ 3960 and
+ *      the trail closes the remainder 1.885 @ 3821.06 (the tape shape).
+ *   B. LOW-first bar with the same deficit at the high -> the trail fills
+ *      BEFORE the extreme on the path -> no slice (fail-closed chronology
+ *      is preserved, the hook is not simply switched on for trails).
+ *   C. Emulator off -> nothing fires.
+ *   D. Arming pin: an EXPLICIT trail_offset=0 arms from the placement close
+ *      exactly like an OMITTED trail_offset (round 10 family AC); the #148
+ *      retro-arm is closed by the family-Z restart at the command layer.

+ * the 22 lab tv pins of ledger note log-20260905t053924z-15615295, see
+ * test_stop_entry_admission.cpp for the tapes).
+ *
+ * Under margin simulation (margin_long_/margin_short_ > 0) a stop entry is
+ * admitted twice: at PLACEMENT — floored qty * tick(close of the call bar) *
+ * margin% <= strategy.equity, a rejected call is dropped and never rests —
+ * and at the FILL — the same qty * tick(fill price) <= realized equity,
+ * where the fill price is the LEVEL on an intrabar touch and the rounded
+ * OPEN on a gap-through (KI-62's original "costs the bar open on a touch"
+ * premise was refuted by fresh-touch-once: TV fills 890 x 11.23 with the
+ * open at 11.29). A declined fill is CANCELLED (not parked) — an arm-once
+ * entry silently dies; a Pine-level reissue re-posts and fills at the first
+ * admissible bar. Under-margined ADMITTED fills are margin-called at bar end
+ * by the existing KI-31 cascade (unchanged). margin=0 is byte-identical.
+ *
+ * The scenarios below keep their original final-state assertions; the
+ * per-bar mechanics noted in each case are the round-7 rule's.

+ * Production-readiness probe (WS1/#7). Engine-only.
+ *
+ * Skeptic's objection: "every probe runs at mintick 0.01. Does the directional
+ * stop-entry snap (long ceil / short floor) actually work at futures 0.25, gold
+ * 0.1, FX 0.00001?" The whole corpus + every existing ctest with a sub-tick
+ * SHORT stop uses on-grid prices, so the is_long_stop=false FLOOR branch is
+ * never asserted at a sub-tick price. This pins it, plus the cross-mintick
+ * parametricity of the snap, plus one end-to-end short-stop fill.

+/*
+ * test_multi_tier_exit_precedence.cpp — pin fill behaviour for multiple
+ * partial strategy.exit(..., qty_percent=...) siblings sharing a from_entry
+ * when several of their stop/limit levels sit inside the same bar's range.
+ *
+ * Isolates the mechanism probed by probe-multi-tier-exit and the joat-caldera
+ * 3-tier TP/stop shape:
+ *   - Three partial limit exits (TP1/TP2/TP3) with qty_percent cascade.
+ *   - Three partial siblings that SHARE a stop but have distinct limits.
+ *   - A bar whose OHLC range touches the shared stop AND >=1 limit.
+ *
+ * The engine resolves each sibling independently via resolve_exit_path_fill
+ * on the synthesised 4-waypoint OHLC path (O→H→L→C or O→L→H→C depending on
+ * which extreme is nearer the open). When the path visits a limit first, that
+ * sibling fills at its own limit; when it visits the shared stop first, every
+ * sibling whose limit was NOT already touched fills at the stop level.
+ *
+ * qty_percent cascade: each sibling's reserved_qty is clamped against the
+ * position remaining AFTER already-placed siblings, so a "full" (qp=100)
+ * sibling placed last reserves only the remainder — firing order among the
+ * siblings does not change the per-tier qty. Verified by pinning each tier's
+ * closed qty below.

+//   (a) weekday: lookahead_off advances ON the 15:45 CT bar (the bar closing

+//       Friday's 15:45 bar likewise, the Sunday 17:00 reopen changes nothing;
+//   (b) early close: the shortened session's last bar (Thu 07-03 12:00 CT,
+//       Fri 11-28 12:00 CT);
+//   (c) a CME holiday session that pauses at 12:00 CT and reopens at 17:00
+//       the same day (Labor Day Mon 09-01, Thanksgiving Thu 11-27,
+//       Independence Day Fri 07-04) is NOT a period: TradingView has no daily
+//       bar stamped at it and folds it into the NEXT trade date's daily bar --
+//       no advance on the 11:45 pause bar, none at the 17:00 reopen, the
+//       merged bar advances on the next session's last bar stamped with the
+//       holiday session's open, and its o/h/l/c/v are TradingView's own (the
+//       Jul-7 bar's o 6307.75 is the SUNDAY open and its h 6315 excludes the
+//       holiday session's 6322.75; the volume covers both sessions);
+//   (d) the registry 15m feed's hole Thu 11-27 20:45 -> Fri 11-28 07:15 CT
+//       lies inside the merged Thanksgiving bar and must not complete it;
+//   (e) values = the native bar: close = the settlement (differs from the
+//       15m last print on every day), volume = the daily volume, time = the
+//       daily stamp; x[1] = the previous native day, advancing on the same
+//       bar; lookahead_on leaks the day's FINAL native values from the
+//       session's first 17:00 bar and, on a holiday session's first bar,
+//       the merged next-trade-date bar, held through the pause and reopen;
+//   (f) the day in progress at the range start is absent under both modes
+//       (KI-55), including on its completion bar.
+// The W sites pin the engine's derivation for the merged day's week (the
+// holiday session belongs to the next trade date, so to its week -- the
+// Thu 07-03 17:00 stamp is Monday 07-07's week); that grouping is the
+// engine's rule, not a TradingView pin. The control without a native feed
+// keeps today's aggregator (the holiday session is its own session-day
+// bucket, values the intraday aggregate).

- * These helpers live in pineforge::internal and source PendingOrder-shaped
- * declarations live in src/source/pine_path_resolve_internal.hpp. libpineforge
- * is a STATIC archive, so the symbols resolve at link time even though they
- * are hidden from any .so export table. We call them directly to drive the exact
- * branch logic, AND through the public free functions
- * resolve_exit_path_fill / exit_order_earliest_path_metric_no_trail to
- * reach the anonymous-namespace trail/gap/entry-bar helpers that are not
- * individually addressable.
- *
- * Every expected value below is a closed-form function of the OHLC
- * waypoints with mintick = 0.01 and lands exactly on the tick grid:
- *
- *   - bar_path_uses_high_first: high-first iff |H-O| < |O-L| (ties low-first)
- *   - high-first path: O -> H -> L -> C ;  low-first: O -> L -> H -> C
- *   - within a segment, the FIRST level crossed (smaller parametric t) wins
- *   - an exit stop/limit that GAPS past the bar open fills at the open
- *   - trail arms once the running best crosses the activation level; with no
- *     offset it exits AT the activation level, with an offset it trails best±off
- *   - on the entry bar a no-trail exit on the wrong side of entry is blocked
- *
- * All asserts are real Pine-correct return values derived by instrumenting
- * the engine, not tautologies.

+ * Prearmed strategy.exit brackets resolve on their parent's FILL bar.
+ *
+ * Three tape-pinned shapes, all order-lifecycle semantics:
+ *
+ *  (1a) DUAL-MARKETABLE bracket. bprakaash-new-era-strategy-1-0
+ *       (OANDA:EURUSD 15m, 2025-07-03 / 07-24 / 08-07 / 09-09 13:30Z):
+ *       strategy.entry("Short", qty=1) + strategy.exit("TP/SL 1", "Short",
+ *       qty=1, stop=sl, limit=target) armed on the signal bar with sl BELOW
+ *       the close (so target lands above it). At the fill open both legs are
+ *       marketable (stop 1.17528 < open 1.17646 < limit 1.17879; on 08-07
+ *       stop == limit == open). TV fills the entry at the open and one leg
+ *       at the same open: exit px == entry px, duration 0, PnL 0. Before
+ *       this pin the engine held dual-marketable brackets off the open
+ *       scratch ("no tape exemplar") and gap-filled them the next bar.
+ *
+ *  (1b) TRAIL-carrying leg. stevenygabbyperez-fast-scalper-with-stops
+ *       (NASDAQ:AAPL 15m, 2025-04-03 / 2026-04-27 13:30Z):
+ *       strategy.exit(stop=close*0.99, trail_points=...) armed with a MARKET
+ *       entry; the RTH open gaps below the stop. TV: entry + 'Exit Long' at
+ *       the open (205.54 / 266.09), PnL 0. The trail leg is dormant until
+ *       activation and does not change the breached stop's fill.
+ *
+ *  (2)  RELATIVE-TICKS bracket of a parent that fills INTRABAR.
+ *       quantbyboji-nq-hma-midday-strategy (OANDA:EURUSD 15m, 2025-08-22
+ *       18:15Z): resting limit 1.17323 fills mid-path (open 1.17356), the
+ *       loss leg binds to the fill price and resolves on the remaining path
+ *       of the same bar (exit 1.17322). 140/141 sibling exits whose parent
+ *       filled at the open already matched; only the mid-path fill deferred
+ *       the child to the next bar's open.

+ * A valid strategy.exit bracket can be armed before its from_entry MARKET
+ * parent fills. When the parent opens at the next bar's open and that open has
+ * already breached the retained stop, TradingView scratches the new position
+ * at the same open. This applies to parents placed from true flat and to
+ * opposite-side market reversals. Correctly-sided stops continue to walk the
+ * remaining entry-bar path and fill at their level.
+ *
+ * The six cells mirror the clean-room TradingView probe
+ * order-market-reversal-resting-bracket-gap-01 (A-F).
+ *
+ * The LIMIT-leg cells below pin finding 278 seed (b)
+ * (rhyme17-trendline-and-horizontal-breakout, six tape events): on a
+ * reversal fill bar TV still honors the STANDING prior-bar strategy.exit
+ * whose levels were computed from the OLD (reversed-away) position's avg
+ * price. A limit already marketable at the fill bar's open fills AT THE
+ * OPEN — a duration-0 PnL-0 trade for the new position — and the re-priced
+ * bracket issued at that bar's close governs afterwards. Equality with the
+ * open is marketable (2025-04-07 14:00 UTC: entry and exit both 1549.51).
+ *
+ * Scope: these cells exercise exit ORDER lifecycle only (when a standing
+ * strategy.exit may fill on its parent's fill bar). They do not touch the
+ * reverted same-bar position_size visibility class, the #146 same-tick
+ * close+reverse sequencing kernel, or ordinary non-reversal exit re-issues
+ * (see the OngoingPositionReissue control).

+/*
+ * test_pyramiding_count_partial_drain.cpp — `pyramiding` bounds the number of
+ * OCCUPIED ENTRY SLOTS in the current directional position, tested at
+ * admission time. A slot is returned when the entry is retired by a CLOSE-PATH
+ * order (strategy.close / close_all / reversal / broker close) and is NOT
+ * returned when another logical entry's BRACKET drains it by FIFO. R20 adds
+ * the proved ordinary two-distinct-ID exception: brackets fully retiring
+ * their own unique lot release its slot if no earlier foreign/ambiguous
+ * bracket slice shadowed it. Reaching flat releases every slot.
+ *
+ * Bug (pre-fix): settle_position_after_partial_exit() unconditionally
+ * re-derived position_entry_count_ from pyramid_entries_.size(). A
+ * strategy.exit bracket fill that DRAINED an entry leg while the position
+ * stayed open therefore handed the pyramid slot back, and the next
+ * same-direction market entry filled an add TradingView rejects.
+ *
+ * Ground truth (clause 4 — bracket drain PINS the slot) —
+ * thulashimohanr-prev-day-week-levels-or-vwap-strategy, pyramiding=2,
+ * ETH-USDT-USDT 15m (all times UTC):
+ *
+ *   2026-03-26 09:45  SHORT 2u @2082.49                     entry #1
+ *   2026-03-26 17:45  ShortT1 limit 2042.49 fills 1u        (never flat)
+ *   2026-03-27 09:45  SHORT 2u @2043.29                     entry #2  (TV admits)
+ *   2026-03-27 10:30  limit 2003.30 fills 1u = the 03-26 remnant
+ *                     -> the 03-26 leg drains; pyramid_entries_.size() 2 -> 1
+ *   2026-03-29 09:45  SHORT would be entry #3 > pyramiding 2  TV REJECTS
+ *
+ * Both retirements of the 03-26 entry were `strategy.exit` T1 bracket fills,
+ * i.e. the entry was FULLY closed and TV still refused the third entry.
+ *
+ * The price gate on 2026-03-29 is unambiguously true (09:30 close 1997.67 <
+ * vwap 2003.236 and < orMid 2001.60) and the strategy.exit calls in the SAME
+ * if-block did execute (the carried stops re-armed from orHigh(03-27)=2051.11
+ * to orHigh(03-29)=2003.61 and fired at 11:00). Pine ran the block; TV's
+ * broker emulator refused only the entry. Tape-wide rescan of
+ * 2025-03-31..2026-04-30 confirms 2026-03-29 is the ONLY day TV skipped a
+ * gate-satisfied OR entry, 15 entries occurred at streak=2 (all admitted) and
+ * ZERO at streak=3.
+ *
+ * Ground truth (clause 3 — close-path retirement RELEASES the slot) —
+ * 3commas-ena-grid-bot-long-strategy, pyramiding=200: 1021 entry fills over
+ * only 64 REUSED entry ids, 776 entries accumulated between two flats, and
+ * never more than 50 CONCURRENT open entries. Every exit is
+ * strategy.close("L"+i) — zero strategy.exit calls in the script. TV admits
+ * all 1021. A counter that never released would refuse 576 of them. The same
+ * shape holds for the xau grid (pyramiding=50, 48 levels, 839 units traded).
+ *
+ * Fix: settle_position_after_partial_exit() takes the reduction cause. Only
+ * PositionReductionCause::BRACKET_EXIT keeps the counter monotone
+ * (std::max against pyramid_entries_.size()); every other cause re-derives it
+ * from pyramid_entries_.size(). The cause is derived at the EXIT-order fill
+ * site from the kClosePrefix ("__close__") id stamp that strategy.close /
+ * close_all put on their materialised EXIT orders.
+ *
+ *   A. locus-2 shape: entry A 2u, BRACKET partial exit 1u, entry B 2u
+ *      (count=2), BRACKET partial exit drains A's remnant, third
+ *      same-direction MARKET entry is REJECTED — no fill event, no trade row,
+ *      position untouched.
+ *      (RED pre-fix: the drain reset count to 1 and the third entry filled.)
+ *   B. counterfactual: after a full close the counter resets and the very
+ *      same entry call admits again.
+ *   C. a partial exit that does NOT drain a leg is inert either way (the
+ *      second entry still admits) — pins that the fix only bites on drain.
+ *   D. the grid-bot clause: A's exact shape but the draining exit is
+ *      strategy.close("A", qty=1) instead of a bracket leg — the slot IS
+ *      returned and the third same-direction entry is ADMITTED.
+ *      (RED under the unconditional-monotone rule: count stays 2 and the
+ *      third entry is refused, which is the 3commas-ena regression.)

+/*
+ * test_range_end_close.cpp — TradingView's range-end accounting: a position
+ * still open after the final bar is reported as a CLOSED trade whose exit
+ * leg is the last bar at that bar's close.
+ *
+ * Evidence (the ws-report-v1 tape the campaign grades against): orb-lite on
+ * NYSE:F 1D reports "Entry short 2026-03-16 @ 11.82, Exit 2026-04-30 @ 12.08",
+ * exit Signal EMPTY, closedTrades:1 — 12.08 is the last close of the range.
+ * On the f-1d spark set 8/10 engine runs held the same position to the last
+ * bar (bars-in-market = TV Duration + 1) and 7/10 had a mark-to-market open_pl
+ * equal to TV's row to the cent, so the row is exactly the open position
+ * marked at the last close. The engine exported closed trades only (trades_
+ * grows in emit_close_trade alone; no end-of-feed flatten in either run
+ * loop) and was one trade short on every such probe. Operator decision
+ * 2026-09-02: the engine emulates the row (engine_orders.cpp,
+ * record_range_end_close_trades) — in the REPORT: the row is built with the
+ * ordinary close arithmetic and merged behind the script's closed trades by
+ * fill_trades_section, while the live position, trades_ and the realized
+ * sums stay as the bar loop left them (a stream continues that position).
+ *
+ * Pins:
+ *   A. Open LONG at end: the report carries one extra closed trade, flagged
+ *      open_at_end, exit on the last bar (index, label timestamp) at the
+ *      last close; pnl is the mark-to-market of that close. The live
+ *      position is still LONG and trade_count() is still 0.
+ *   B. Flat at end (closed by the script): the report is unchanged and no
+ *      row carries the flag.
+ *   C. Open SHORT at end: mirror of A with the short sign; matches the
+ *      orb-lite row shape (entry 11.82, last close 12.08 -> -0.26 on qty 1).
+ *   D. Commission is applied like any close (0.1% on both legs): the row's
+ *      commission equals entry_price*qty*0.001 + exit_price*qty*0.001 and
+ *      pnl is net of it — the same arithmetic test_metrics pins for
+ *      script-driven exits.
+ *   E. The mark is the mintick-rounded close with NO slippage: a sub-tick
+ *      last close 12.083 books 12.08 even with slippage 2 ticks set (a
+ *      script close on the same bar would have booked 12.06).
+ *   F. Equity curve: every point before the last is byte-identical to a
+ *      run that stops one bar earlier; the last point is re-marked to the
+ *      flat account so equity == capital + net_profit + open_profit(0)
+ *      holds, and the report's net_profit / total_trades include the row.
+ *   J. Drawdown / run-up: the compute_equity_stats curve walk reproduces the
+ *      engine's scalar extremes with commission and a position open at the
+ *      end whose last bar is the trough (and, mirrored, the peak) — the
+ *      scalars are re-folded from the re-marked curve. A first cut re-marked
+ *      the point and left the scalars at the gross fold, and the two
+ *      disagreed by the row's commissions exactly there.
+ *   G. Pyramiding: two open slices produce two flagged rows, one per entry,
+ *      like every other full close.
+ *   H. Aggregated path (1m input -> 5m script): the exit is dated on the
+ *      script bar's LABEL (the equity curve's time_ms) and indexed by the
+ *      script bar, not the last input minute.
+ *   I. Identity (round-4b F3): the range-end row carries the open lot's
+ *      entry_incarnation like any other close, and the C ABI accessor
+ *      strategy_closed_trade_entry_incarnation reads it at the row's REPORT
+ *      index (behind the script's closed trades). Pre-fix the accessor
+ *      bounded the index by trade_count() == trades_.size() and returned 0
+ *      for every range-end row; run_strategy.py then wrote an empty
+ *      "Engine entry incarnation" for the row, the grader failed closed on
+ *      the identity gate and the verifier ladder rejected the TV-identical
+ *      trim candidate for ena-grid (XAUUSD 1D).

+/*
+ * test_reversal_admission_float_guard.cpp —
+ * design-reversal-admission-float-guard.
+ *
+ * The KI-54 fill-time margin admission gate (engine_fills.cpp) compares
+ *
+ *   required = |frozen_default_qty| * admit_price * pointvalue * fx * margin/100
+ *   free     = sizing_equity - held          (held == 0 unless same-direction)
+ *   decline iff required > free + epsilon
+ *
+ * The epsilon used to be widened by ONE WHOLE LOT of notional
+ * (qty_step * admit_price * ...) on every arm of that gate. The stated
+ * justification was that the frozen quantity was floored to the lot step, so a
+ * shortfall smaller than the unspent remainder is "a coin flip on where the
+ * floor happened to land", and — decisively — that widening by one lot "keeps
+ * every decline that TV's exports actually confirm (their margins exceed a lot
+ * of notional)". That last clause is an empirical claim about the ABSENCE of
+ * sub-lot ground truth.
+ *
+ * WHAT FALSIFIED IT (reversal arm only). A scraped 13-month ETHUSDT.P row
+ * (chartprime-power-order-blocks-chartprime; percent_of_equity = 100, margin
+ * 100, qty_step 0.0001) carries 2,419 TradingView reversal decisions: 94
+ * declines and 2,325 admits. 92 of the 94 declines have margins BELOW one lot
+ * of notional. On an all-in reversal the whole decision lives inside
+ * [0, qty_step * admit_price) by construction — the order spends the entire
+ * equity — so the widening does not blunt this arm's gate, it makes it INERT:
+ *
+ *   epsilon = one lot     ->  2/94 declines caught, balanced accuracy 51.1 %
+ *   epsilon = float guard -> 86/94 declines caught, 6/2,325 wrongly cancelled,
+ *                            balanced accuracy 95.6 %
+ *
+ * Board-wide the tightened arm would cancel 18 of 23,785 TradingView-ADMITTED
+ * all-in reversals (0.08 %); only 1 of those 18 is above one lot.
+ *
+ * Scope: the one-lot term is REMOVED ON THE REVERSAL ARM ONLY. The flat-open
+ * arm and the same-direction-add arm keep it — each is separately TV-pinned,
+ * nothing has falsified their premise, and the "coin flip" argument genuinely
+ * does apply to them (they price at the SIZING price the quantity was floored
+ * against, so any residual really is floor luck). On a reversal the quantity is
+ * floored against the PREVIOUS bar's close while the order fills at THIS bar's
+ * open: the overshoot is an observable gap, not floor luck.
+ *
+ * Pins below (A-D are the reversal arm; E and G are the scope controls that
+ * must NOT move; F rides the SEPARATE true-flat gap-reject upstream of KI-54,
+ * which has since dropped its own one-lot slack — design-cntvxiao-gap-reject):
+ *   A. Reversal, adverse gap costing LESS than one lot -> DECLINED (the RED:
+ *      base admits this).
+ *   B. Reversal, zero gap (required == free exactly) -> ADMITTED. The guard is
+ *      a strict `>`; a `>=` would cancel every ordinary flip.
+ *   C. Reversal, favourable gap -> ADMITTED.
+ *   D. Reversal, adverse gap far above one lot -> DECLINED (unchanged).
+ *   E. SCOPE: same-direction add whose shortfall is under one lot -> still
+ *      ADMITTED (the add arm keeps the widening), and its above-one-lot
+ *      sibling is still DECLINED. This pair is what proves the term is still
+ *      load-bearing where it was left in place.
+ *   F. Flat open on the SAME sub-lot adverse gap as pin A -> DECLINED by the
+ *      true-flat zero-commission gap-reject upstream of KI-54, which no
+ *      longer grants one lot of slack: TV cancels on ANY positive shortfall.
+ *   G. SCOPE: qty_step == 0 (no lot quantization) is unchanged by definition —
+ *      the one-lot term was already zero there, so base and patched must agree.
+ *
+ * Every fixture uses mintick 0.01 on-tick prices, zero slippage, zero
+ * commission and margin_call_enabled_ = false, so the only mechanism under test
+ * is the admission comparison itself.

+ * arithmetic question"). The run_strategy --trace-json of the trigger terms
+ * (spark, engine 12f9707) showed every term TRUE on the 02-06 finals in

+ *       02-07 open. loss = 2513.61 = the short's open profit at the 02-06
+ *       open 62909.87; base = 102513.6 = day-start equity WITH the open
+ *       profit (2.4520%): the closing fill's own realized P&L is not yet in
+ *       the equity TradingView checks at that tick.
+ *   t6  the short held through 02-06 with short adds P5/P6: at 1.0% and
+ *       1.1% every lot is closed at the HIGH 71751.33 as "Close Position
+ *       (Max intraday Loss)" (loss there 1208.6 = 1.18%); P6 from the
+ *       close calc is dropped, P7 fills 02-08.
+ *   t9  after the exit a recalc-born short R6 0.15 (fills 60000, -1763 at
+ *       the high): no fire at 3.0% — the booked +2699 counts (1578 = 1.54%).

+ * The old engine rule summed REALIZED P&L per chart-tz day and latched a

+// src/engine_run.cpp.
+//
+// Three concern groups, each pinning Pine-correct behaviour:
+//
+//   1. get_input_double / int / int64 / bool / string (lines 557-599):
+//      valid parse, fallback-on-garbage (the catch(...) arms on bad numeric
+//      strings), and the "true"/"1"/"false"/"0" bool grammar. These back the
+//      generated code's input.* lookups; an operator override string that
+//      cannot be parsed must silently fall back to the Pine default rather
+//      than throw across the engine.
+//
+//   2. The run-with-overrides overload (lines 624-669): apply a
+//      StrategyOverrides struct (initial_capital, pyramiding, slippage,
+//      commission_value/type, default_qty_value/type, process_orders_on_close,
+//      close_entries_rule), run a strategy, and assert the report/equity
+//      reflect each field — initial_capital flows to equity, pyramiding caps
+//      the number of same-direction market legs, commission reduces realized
+//      PnL, process_orders_on_close changes the market fill price.
+//
+//   3. The timeframe auto-detection branch (line 301): call the TF-aware
+//      overload with an EMPTY script_tf (and empty input_tf) so
+//      detect_timeframe runs over the bar timestamps; assert the report's
+//      input_tf_seconds / script_tf_seconds match the detected median delta.
+//

+ * test_same_bar_add_exit_coverage.cpp — KI-62 keep-vs-scratch (probe-pinned).
+ *
+ * When a pre-queued SAME-ID MARKET pyramid add and a from_entry PRICED bracket
+ * exit both fill on the same bar, TradingView's open-tick fill priority is
+ *   buy-market-like (market + triggered buy stops)
+ *     -> sell-market-like (market + triggered sell stops)
+ *       -> gapped-through limit orders (both sides, at the open, last).
+ * The exit covers the add (the add scratches dur-0) iff the add's fill
+ * precedes-or-ties the exit's fill in that sequence. Intrabar exit fills
+ * (open inside the bracket, level hit AFTER the open) process after every
+ * open fill, so they always cover an open-filled add.
+ *
+ * Mapping the collision (add is always a market order; the exit closes the
+ * position so it is the opposite side):
+ *   add prio  = LONG add -> buy(1),  SHORT add -> sell(2)
+ *   exit prio = gapped STOP -> (SHORT pos buy-stop = 1, LONG pos sell-stop = 2)
+ *               gapped LIMIT -> 3 (either side)
+ *               intrabar     -> 4 (after all open fills)
+ *   scratch iff add_prio <= exit_prio.

- * test_same_id_stop_replace.cpp — verify TradingView's same-id
- * strategy.entry replacement timing relative to the bar's
- * process-pending-orders pass.
- *
- * Pine v6 contract (verified empirically against
- * validation/62-same-id-stop-cross-before-modify):
- *
- *   bar B-1 places stop A.
- *   bar B begins:
- *     1. broker evaluates pending orders against bar B's OHLC. If A's
- *        stop is touched, A fires here at A's stop price. The fill is
- *        recorded BEFORE strategy logic runs, so ``strategy.position_size``
- *        on bar B already reflects A's fill.
- *     2. on_bar (strategy logic) executes. Any ``strategy.entry`` call
- *        with the SAME id replaces what's left in pending_orders_:
- *        - if A fired in step 1, pending_orders_ no longer has A; the
- *          new placement just adds A' for bar B+1 onward.
- *        - if A did NOT fire in step 1, A is removed and A' takes its
- *          place; A' is evaluated on bar B+1 (engine ran step 1 already).
- *     3. There is no second pass over bar B for A' — TV's reference docs
- *        describe pending-order updates as bar-boundary events, not
- *        intra-bar. The engine's bar pump enforces this by calling
- *        ``process_pending_orders`` exactly once before ``on_bar`` in
- *        the !process_orders_on_close path.
- *
- * The three scenarios below exercise each branch of the contract.

+// test_session_predicates_daily_chart.cpp — session.ismarket / ispremarket /
+// ispostmarket / isfirstbar / islastbar on a DAILY-OR-HIGHER chart.
+//
+// TradingView ground truth (Pine reference, Sessions): on "1D" and above
+// session.ismarket is true on every bar and session.ispremarket /
+// session.ispostmarket are false — a daily bar covers whole session days,
+// not a time of day. Intraday charts keep the time-of-day test unchanged.
+//
+// Evidence: roi10x-shiva-lt-ls-blend on OANDA:XAUUSD @1D. The symbol's
+// session is 1800-1700 America/New_York and its daily bars are stamped at
+// the 17:00 ET break (minute 1020, outside the wrapped window [1080, 1020)),
+// so the time-of-day test never held, every signal ANDed with
+// session.ismarket stayed false, and the engine took 0 trades against
+// TradingView's 57.
+//
+// Codegen lowers the three predicates to the UNQUALIFIED call
+//   pine_session_ismarket(syminfo_.session, syminfo_.timezone, current_bar_.timestamp)
+// inside the generated `class GeneratedStrategy : public BacktestEngine`
+// (pineforge_codegen/codegen/visit_expr.py). The harness below makes the
+// same unqualified calls from a BacktestEngine subclass, so it proves the
+// class-scope members (engine.hpp) shadow the namespace-scope time-of-day
+// forms for the emitted code — if that shadowing ever broke, the daily
+// assertions here would fail at runtime.

+/*
+ * test_sizing_basis_mintick.cpp — TradingView's broker sizes DEFAULT (qty=na)
+ * percent_of_equity / cash market orders on the MINTICK-ROUNDED signal close:
+ *
+ *   basis(S) = round_to_mintick(close(S))            (census form, no epsilon)
+ *   qty      = floor_step( E / basis(S) ),  E marked at basis(S) as well
+ *
+ * Pine's own signal path (ta.*, crossovers) keeps reading the RAW feed close;
+ * only the broker's sizing snapshot and the fill are on-tick. Evidence (the
+ * replay this file pins): 674/674 NYSE:F and 832/832 NASDAQ:AAPL reversals of
+ * taro-s-c-c-ma-simplified-2-color fit the rounded basis while the raw close
+ * fits 476/674 on F; drgunjan-F trade 1 is TV qty 10460 = floor(100000/9.56)
+ * on a 9.565 close where the raw divisor gave 10454; and the raw basis
+ * DECLINED entries TV filled whenever an x.xx5 close rounded UP at the fill
+ * (qty floored on the lower raw price times the higher rounded fill overshot
+ * the sizing equity by ~qty*mintick/2 and tripped the true-flat gap-reject /
+ * reversal float-guard arms): 463/463 missing taro-F entries predicted, 0
+ * counterexamples; 26/26 drgunjan-F and 6/6 mazi-F missing entries sit on
+ * sub-penny signal closes.
+ *
+ * Pins:
+ *   A.  9.565 close, mintick 0.01, capital 100000, pct 100, next open 9.56:
+ *       frozen qty == 10460 (drgunjan-F trade 1) and the entry FILLS.
+ *   A2. 9.585 close (rounds UP to 9.59), next open 9.59: the entry FILLS with
+ *       qty 10427. Pre-fix: qty 10432 floored on 9.585, 10432*9.59 = 100042.88
+ *       > 100000 -> the true-flat zero-commission gap-reject arm DROPPED it on
+ *       a zero-gap open (the 463/463 mechanism).
+ *   A3. The reversal twin of A2: a held long, short signal on a 9.585 close,
+ *       reversal fills at 9.59. Pre-fix the equity mark at the raw 9.585 left
+ *       free_funds 100894.71 against a required 10526*9.59 = 100944.34 and the
+ *       float-guard reversal arm DECLINED; on-tick the mark is 9.59, free
+ *       funds 100947.34, admitted.
+ *   B.  A penny close (9.56) is unchanged in every quantity and verdict:
+ *       basis == close to within one ulp (double(0.01) is inexact, so
+ *       round_to_mintick is not a bit-for-bit identity on decimal ticks —
+ *       the ulp is absorbed by apply_qty_step's 1e-6 nudge and the
+ *       admission float guards), qty 10460, fills.
+ *   C.  mintick 0.25 (futures): a 5000.125 close sizes on 5000.25 (nearest,
+ *       floor(x/tick + 0.5)); capital 100003 floors to 19 lots where the raw
+ *       basis gave 20.
+ *   D.  Slippage ticks are added AFTER rounding: 9.565 with slippage 2 sizes
+ *       a buy on 9.58 and a sell on 9.54 (pre-fix 9.585 / 9.545).
+ *   E1. SHORT margin-call cascade marks at the ROUNDED high (medium evidence:
+ *       32 vs 0 reproduced slices on the F tape): a sub-tick excursion the
+ *       on-tick ledger cannot see (high 100.004 on a short at liq 100.00)
+ *       fires NO slice; pre-fix the raw mark produced a phantom one.
+ *   E2. The slice quantity at a 105.005 high is the 105.01-marked 3.8167794
+ *       (pre-fix 3.8131518 from the raw mark); the fill price was already
+ *       105.01 both ways (bar_fill_price, finding-446).
+ *   E3. The chronological copy of the cascade (margin_call_slice_before_
+ *       priced_exit, the slice taken BEFORE a same-bar priced exit) marks at
+ *       the same rounded high: E1's 100.004 excursion with a TP limit
+ *       resting on the bar fires NO slice and the TP closes the full lot
+ *       (pre-fix that path marked raw and fired a phantom 0.0016 slice only
+ *       when an exit happened to be resting); the on-tick control high
+ *       100.01 with the same TP slices 4*(10 - 999.9/100.01) @ 100.01 first
+ *       and the TP closes the remainder, proving the path is live.
+ *   F.  Sanity on the helper itself: round_to_mintick on the drgunjan close
+ *       and idempotence on its own output.

+ * test_sparse_atr_prev_close.cpp — issue #178: ta.atr() / ta.tr() called

+ * BINANCE:BTCUSDT 60 2025-04-01..07-01, ws-report-v1 rangeProof covered,

+ * four qty-encoded sensors on every sparse execution (398 executions of
+ * `if close[1] > open[1] and close < open`):
+ *   B = ta.atr(3) inside the block
+ *   C = ta.rma(chartTR, 3) inside the block, chartTR = ta.tr(true) EVERY bar
+ *   A = ta.rma(trA, 3) inside the block, trA built from the close of the
+ *       PREVIOUS EXECUTION of the block (the engine's per-object prev_close)
+ *   T = ta.rma(ta.tr(true), 3) with ta.tr(true) itself inside the block
+ * Result: B == C == T on 398/398 executions, B == A on 0/398. So the RMA
+ * advances on the executions only, but the true range always reads the
+ * previous CHART bar's close (close[1]) — never the previous execution's.
+ *
+ * The engine's ta::ATR / ta::TR keep a per-object prev_close that only
+ * moves when compute() is called, which is exactly model A. This test pins
+ * the 4-argument form (prev chart close handed in by the caller) and the
+ * BacktestEngine::prev_chart_close() tracker a sparse call site must feed it.
+ *
+ * NDEBUG-PROOF: every assertion uses the returning CHECK macro.

+/*
+ * test_stop_entry_admission.cpp — round 7: TradingView's admission of a
+ * strategy.entry(stop=) under margin simulation, pinned by 22 `lab tv`
+ * tapes (2026-09-05, ledger note log-20260905t053924z-15615295, rule and
+ * call-by-call table scratchpad/r7/pins/flatten-PINS.md, tapes
+ * scratchpad/r7/pins/flatten-<slug>/tv_trades.csv, sources <slug>.pine).
+ *
+ * The pinned rule (margin_long/short > 0, default process_orders_on_close):
+ *
+ *   1. PLACEMENT on the bar B of the call: accepted iff
+ *        lot_floored(qty) * tick_half_up(close(B)) * pv * fx * margin%/100
+ *          <= strategy.equity(B) as the script reads it
+ *      (post-exit realized equity on a flattening bar; on a reversal only
+ *      the new side counts; a position closed on B counts nothing). Not the
+ *      raw sub-tick close, not high/low, not the level.
+ *   2. A rejected placement is DROPPED, never re-evaluated; a rejected
+ *      same-id re-issue also CANCELS the resting order of an earlier
+ *      accepted issue; qty is recomputed only by the script's next call.
+ *   3. An accepted order rests until touched; later closes are not
+ *      re-checked.
+ *   4. FILL: the same floored qty * tick(fill price) <= equity at the fill,
+ *      where the fill price is the LEVEL on an intrabar touch (not the bar
+ *      open — the engine's KI-62 premise was wrong) or the rounded open on
+ *      a gap-through; a rejected fill drops the order (no partial / trim).
+ *   5. Market re-entries on the flattening bar keep the round-5 market rule.
+ *
+ * Scope: the explicit-qty / default FIXED / CASH / default percent > 100
+ * sizing partition (every tape passes an explicit qty). A DEFAULT
+ * percent_of_equity <= 100 stop takes the SAME placement half with its own
+ * quantity — sized at the tick-snapped LEVEL, family K, ledger note
+ * log-20260905t084529z-c7b22df1, tests/test_default_pct_stop_sizing.cpp —
+ * and the same fill half on that quantity; KI-62's bar-OPEN basis is
+ * retired. The ahtisham regression at the end of this file
+ * (cand-round7-engine-a-20260905: costing the all-in default at the level
+ * with a FILL-time quantity admitted 394 short touches TV never fills) is
+ * now explained by the placement half: the all-in sell stop below the
+ * close is never placed.
+ *
+ * Feed bars are the registry's NYSE:F 15 (mintick 0.01, whole shares) and
+ * OANDA:XAUUSD 15 (mintick 0.005, lot 0.01) bars, UTC, `lab bars`. Tape
+ * times are UTC+8 in the CSVs; they are quoted here in UTC.
+ *
+ * Engine (c2032d1) pre-fix: no placement check on stops at all, and the
+ * fill-time gate costed the bar OPEN. Every "TV result" column below is
+ * what the tape shows; the "pre-fix" notes say what the engine did.

+ * Production placement-frozen STOP sizing semantics (round 7, family K).
+ *
+ * A DEFAULT percent_of_equity <= 100 pure STOP is sized when strategy.entry
+ * is called — at the tick-snapped level, or at tick(close) when the level is
+ * already at/beyond the close (TV's market-at-next-open order) — and is
+ * placement-checked on that quantity at tick(close) (family E). The frozen
+ * quantity is what admission costs and dispatch opens on every fill shape
+ * (gap-through, intrabar touch, delayed touch); it is never re-sized while
+ * resting. Non-default sizing, limit and stop-limit shapes carry no snapshot.
+ *
+ * Rule, tapes (scratchpad/r7/pins/f15-stopsize-*) and the ahtisham decode:
+ * PendingOrder::default_stop_placement_qty (engine.hpp) and
+ * tests/test_default_pct_stop_sizing.cpp. Before this round the snapshot
+ * was a next-open-only, all-in, margin-100 special case sized at the CLOSE;
+ * the expectations re-pinned here are listed in the commit.

+ * test_stop_tick_rounding.cpp — round 6, design-stop-tick-rounding:
+ * TradingView's broker emulator tests a resting stop / limit against the
+ * bar's OHLC QUANTIZED to the tick (nearest, floor(p / mintick + 0.5)) while
+ * the order LEVEL stays raw; the fill keeps its directional / limit-or-better
+ * snap. The engine used to compare the RAW bar prices, so a sell-stop at
+ * 13.74624 fired on a 13.745 low that TradingView (low -> 13.75) walks past.
+ *
+ * Every case below is a `lab tv` tape on NYSE:F 1D (mintick 0.01, sub-penny
+ * prints; scratchpad/r6/pins/stopround-*, 2026-09-04) replayed on the feed's
+ * own bars (tape times are UTC+8 evenings of the same trading day):
+ *
+ *   stopround-xs-L-{1374624,137451,137449,13745}  long sell-stop, entry
+ *       01-28 @13.88: every one SKIPS the 02-02 bar (low 13.745) and fills
+ *       02-03 @13.74.
+ *   stopround-xs-L-133449   long sell-stop 13.3449, entry 01-22 @13.78:
+ *       fills 01-26 (low 13.3448) @13.34 — so the level is NOT floored
+ *       before the compare (13.34 vs 13.3448 would not fire) and the bar is
+ *       NOT raw (02-02 would fire): only the quantized low explains both.
+ *   stopround-xs-S-{140349,1403505,140352}  short buy-stop, entry 01-30
+ *       @13.91: all fill 02-03 (high 14.0351 -> 14.04) @14.04.
+ *   stopround-xs-S-140351   short buy-stop 14.0351, entry 02-19 @13.77:
+ *       fills 02-20 (high 14.035 -> 14.04) @14.04.
+ *   stopround-xs-S-13225-high  short buy-stop 13.225, entry 12-08 @13.07:
+ *       skips 12-09 (high 13.2202 -> 13.22), fills 12-10 @13.23 — the
+ *       high rounds to NEAREST, not up.
+ *   stopround-xs-L-13776-open  long sell-stop 13.776, entry 02-19 @13.77:
+ *       the 02-20 open 13.775 (-> 13.78) is NOT a gap; fills at the level
+ *       13.77, not at the open.
+ *   stopround-xl-L-{140349,1403505,140352}  long sell-limit -> 02-03 @14.04;
+ *   stopround-xl-S-{137451,137449} short buy-limit -> 02-03 @13.74;
+ *   stopround-xl-S-133449  short buy-limit -> 01-26 @13.34.
+ *   stopround-es-L-{140349,1403505,140352} / stopround-eo-L-1403505
+ *       strategy.entry / strategy.order long stop placed 01-30 -> fill
+ *       02-03 @14.04; stopround-es-S-{137451,137449} short stop -> 02-03
+ *       @13.74.
+ *   stopround-el-L-{137451,137449} long limit entry placed 01-30 -> 02-03
+ *       @13.74; stopround-el-S-{1403505,140352} short limit entry -> 02-03
+ *       @14.04.
+ *   stopround-xt-L-trail  long entry 02-19 @13.77, trail_points 20 /
+ *       trail_offset 3: exits 02-23 at the open 13.98 — the raw-extreme
+ *       trail behaviour the engine already had (a quantized 14.04 best
+ *       would have filled 02-20 @14.01). The trail is NOT quantized.
+ *   stopround-ohlc-{0,1}  Pine's own low / high (encoded in the trade qty)
+ *       are the raw prints 13.745 / 13.3448 / 14.0351 — the feed's values —
+ *       so the quantization is the broker's, not the data's.

+ * src/engine_strategy_commands.cpp.
+ *
+ * Mirrors tests/test_strategy_oca.cpp / test_strategy_pyramiding.cpp /
+ * test_integration.cpp: subclass BacktestEngine, override on_bar to drive
+ * the strategy.* command surface, and snapshot pending_orders_ / position
+ * state each bar so the test can pin Pine-correct expected values.
+ *
+ * Targets (engine_strategy_commands.cpp uncovered lines):
+ *   - trade-start-time buffer gate (60-69): current_ms >= start_ms - (one
+ *     script TF) * 1000. With 1-minute bars the buffer is 60_000 ms.
+ *   - strategy_cancel_all() clears pending orders (374-376).
+ *   - strategy_order raw-order reset of limit/stop to NaN (415-418).
+ *   - purge_exit_orders() paths via execute_immediate_close (546-559).
+ *   - explicit-qty exit reservation with a NaN-qty percent sibling
+ *     (310-321) and the same NaN-qty percent accounting inside
+ *     compute_exit_reserved_qty (666-668).
+ *
+ * NDEBUG-proof: uses a returning CHECK + failure counter; main() returns

+ * test_strategy_pyramiding.cpp — verify TradingView's deferred-flip
+ * carry consumption rule on BacktestEngine.
+ *
+ * Background: a priced (stop/limit) entry placed while a position was
+ * open captures that position's qty into ``PendingOrder::tv_carry_qty``
+ * at placement time. If the source position is later closed and the
+ * priced entry now fires from FLAT in the OPPOSITE direction, TV opens
+ * the new position at ``base_qty + tv_carry_qty`` (validation/52, 63,
+ * 72, 92, 95, 96 chains). Sibling priced entries (same created_position
+ * cycle, same direction) must lose their carry when one fires from flat
+ * — otherwise probe 93 (pyramiding=2, two opposite-direction stops
+ * armed during separate long cycles) double-grows.
+ *
+ * The cycle-scope predicate is the load-bearing piece: a sibling armed
+ * in a LATER cycle (created_bar > firing order's created_bar) captures
+ * carry from a DIFFERENT source position; it owns its carry and TV does
+ * not pre-emptively wipe it. Without that scope, the next-cycle sibling
+ * fires fresh and the qty schedule shifts by one full cycle, leaking
+ * ~qty × mintick of per-leg PnL drift across the whole chain (probe 95
+ * is the oracle: open-guaranteed stops eliminate sub-bar precision so
+ * any mismatch must come from the carry rule itself).

+ * ACTIVATION (trail_points / trail_price) against the bar's OHLC QUANTIZED
+ * to the tick — the round-6 stop / limit trigger rule (test_stop_tick_
+ * rounding.cpp) extended to the trail's arming — while the trail's running
+ * best (peak / trough) stays the raw print (round 5; stopround-xt-L-trail).
+ *
+ * Pinned with three `lab tv` tapes on NYSE:F 15m, 2025-04-10..18, fixed 100
+ * shares (scratchpad/r7/pins/f15-trail-0415-{reissue,fixed760,fixed754};
+ * campaign note log-20260905t084531z-57cedc55): a short entered at the
+ * 04-15 14:45Z open (9.495 -> 9.49) with
+ *   strategy.exit("XS", "S", trail_points = close * 0.008 / syminfo.mintick,
+ *                 trail_offset = 0)            re-issued every bar, or
+ *   trail_points = 7.60 / 7.54 fixed           (all ceil to 8 ticks),
+ * exits on the 15:45Z bar @9.41 in EVERY tape. Activation = 9.49 - 0.08 =
+ * 9.41; the 15:45Z bar (O 9.43 H 9.45 L 9.415 C 9.445) has a raw low of
+ * 9.415 — above the level, the engine's no-activate, which slid the exit to
+ * the 16:45Z bar (low 9.41) — and a tick-quantized low of 9.41 (9.415 is
+ * 9.41499.. in binary: floor(941.499 + 0.5) = 941), which reaches it; with
+ * offset 0 the trail exits one-shot at the level. Re-issuing trail_points
+ * from the current close is irrelevant (the fixed tapes are identical).
+ *
+ * The bars are the registry feed's (lab bars NYSE:F 15, feed 80f404ae85ef),
+ * UTC-stamped; tape times are UTC+8 evenings of the same day.

+ * test_trail_close_restart_no_fold.cpp — round 10 family Y: a later-bar
+ * strategy.exit re-issue that changes trail_points restarts the trailing
+ * extreme from the issuing bar's CLOSE and nothing else — the issuing bar's
+ * own high/low is NOT part of the new order's path (it starts at the next
+ * bar's open); an offset-only re-issue keeps the running extreme (round 9
+ * family Z's rule E holds on later bars too).

+ * trail_offset=atr*2) re-issued on EVERY bar. The ATR moves every bar, so
+ * every bar's re-issue is a changed request: family Z's close restart. Under
+ * process_orders_on_close the script body runs between the bar's two
+ * process_pending_orders calls, and the second one folded the issuing bar's

+ * (3) The activation level and the trailing level are ON the tick grid: a bar
+ *     extreme landing exactly on the level touches it. 10.11 - 21 * 0.01 is
+ *     9.899999999999999 in doubles, one ulp UNDER the 9.9 low of NYSE:F
+ *     2025-04-03 13:45Z (O 10.165 H 10.18 L 9.9 C 9.9): TV fills the
+ *     zero-offset trail there @9.90 (trail-eq-S-off0-tp21; the probe's own
+ *     20.22 -> 21t case); the engine read the leg as "not reached" and
+ *     gap-filled the next open @9.89. The "stop == trough == close equality"
+ *     reading of that row is REFUTED: trail_points 18 fills the same bar at
+ *     its activation 9.93, not at the 9.90 extreme/close (trail-eq-S-off0,
+ *     and trail-eq-S-omit with the offset omitted); the long twin (entry
+ *     04-01 19:15Z @9.88, trail_points 8) fills 04-02 13:30Z @9.96 = the
+ *     activation on a close == high bar (trail-eq-L-off0). A whole-tick
+ *     offset trails durably and its level is touched inclusively: with
+ *     trail_offset=1 the short fills 04-03 14:00Z @9.90 (trough 9.89 at the
+ *     open + 1t == the bar's 9.90 high; trail-eq-S-off1), the long fills
+ *     04-02 13:45Z @9.97 (peak 9.985 - 1t = 9.975, floored; trail-eq-L-off1).
+ *
+ * Resolver-level pins go straight through resolve_exit_path_fill (as
+ * test_trail_open_arm_subtick_offset.cpp does); engine-level pins run
+ * BacktestEngine end to end over the registry feed bars (`lab bars`).

+ * test_trail_open_arm_subtick_offset.cpp — two trailing-exit rules pinned
+ * from TradingView tapes (winthetrade-ema-9-vwap-strategy-with-atr-trailing-
+ * stop family: strategy.exit("x", trail_points = atr*2, trail_offset = atr*2),
+ * a price-unit ATR passed as TICKS; 7 lanes, entry/exit timestamps exact,
+ * exit PRICE wrong on the same bar).
+ *
+ * (B) The bar's OPEN is the first price a resting trail observes. A trail
+ *     whose activation the open already sits past arms AT the open with
+ *     best = open, so an adverse-first leg fills at open -/+ offset. The
+ *     engine only folded prices in at the END of each path segment, stayed
+ *     dormant through the retrace, armed at the favourable extreme and
+ *     filled at extreme -/+ offset.
+ *       OANDA:XAUUSD 15m long 2025-04-04 10:45Z @3110.31 (POOC close fill);
+ *         11:00Z bar O 3110.40 H 3136.775 L 3109.24 C 3134.46, 15t/15t,
+ *         mintick 0.001: TV 3110.385 (open - 0.015), engine 3136.76.
+ *       NASDAQ:AAPL 15m short 2025-04-02 18:45Z @222.93; 04-03 13:30Z bar
+ *         O 205.54 L 202.52: TV 205.55 (open + 1t), engine 202.53 (low + 1t).
+ *       NYSE:F 1D long 2025-04-21 @9.47; 04-22 O 9.55 H 9.72: TV 9.54,
+ *         engine 9.71.
+ *
+ * (A) A trail_offset whose floor is ZERO ticks (any value in [0, 1)) is
+ *     TV's explicit-zero trail: an activation first reached intrabar is the
+ *     one-shot fill AT the activation; armed (at the placement close, by an
+ *     open past the activation, or by a path extreme) it is a zero-distance
+ *     trailing stop on the raw running best (round 10 family AC,
+ *     test_zero_offset_trail_rides). `lab tv` pin on OANDA:EURUSD 15m
+ *     2025-04-01 -> 05-01: strategy.exit("x", "L", trail_points=3,
+ *     trail_offset=0 / 0.5 / 0.9) produce byte-identical tapes (190 rows,
+ *     sha256 36aa80ac...).
+ *       EURUSD 15m short 2025-03-31 03:45Z @1.08330, atr*2 ~ 0.0006 ticks
+ *         (activation ceil -> 1t = 1.08329, offset floor -> 0); exit bar
+ *         O 1.08330 L 1.08314: TV 1.08329 (activation), engine 1.08314 (low)
+ *         — the old finite-zero distance armed at the low and filled there
+ *         although the activation was first reached intrabar.
+ *
+ * Resolver-level pins go straight through resolve_exit_path_fill (the
+ * runtime-private header, as test_path_resolve_extra.cpp does); engine-level
+ * pins run BacktestEngine end to end, including the POOC close-fill entry
+ * whose carried best is the entry price itself.

+ * test_trail_ref_entry_bar_extreme.cpp — round 9 family Z: a trailing exit's
+ * running extreme is the position's, from its entry fill on, and a re-issued
+ * strategy.exit never restarts it from the issuing bar's close.
+ *
+ * shurben5-tradingview-bot-goat on BINANCE:ETHUSDT.P 15m (registry feed
+ * 27b62431096e; `lab bars`): strategy.exit("TP1 Short", from_entry="Short",
+ * qty_percent=50, profit=100t) + strategy.exit("Exit Short", from_entry=
+ * "Short", profit=300t, loss=100t, trail_points=100t, trail_offset=50t),
+ * both re-issued on EVERY bar (the script calls all four exits
+ * unconditionally), percent_of_equity 100, mintick 0.01, qty step 0.0001.
+ *
+ * TV #663/#664 (2025-12-25 07:15Z, short @2940.36 from flat): the entry bar
+ * O 2940.36 H 2940.36 L 2938.71 C 2938.84 fills TP1 @2939.36, arms the trail
+ * at that same level and runs its extreme down to the bar's LOW 2938.71; the
+ * 07:30Z bar (O 2938.85 H 2939.7) fills "Trail Short" @2939.21 = 2938.71 +
+ * 50t. The engine printed 2939.34 = 2938.84 + 50t: the entry bar's CLOSE.
+ * TV #943/#944 (2026-04-24 22:15Z, short @2313.82 from flat): entry bar
+ * O 2313.82 H 2314.23 L 2311.53 C 2311.85, TP1 @2312.82; the 22:30Z bar
+ * (O 2311.85 H 2312.13 L 2305.2) fills "Trail Short" @2312.03 = 2311.53 +
+ * 50t on its opening rise. The engine trailed from the close (2312.35, never
+ * touched by the 2312.13 high) and rode the bar down to TP2 @2310.82.
+ *
+ * One rule explains both: TradingView's trailing extreme is the position's
+ * best price since the entry fill, walked along every bar's intrabar path,
+ * and a strategy.exit re-issued for a from_entry that is already filled
+ * MODIFIES the resting order — it does not restart the extreme. The engine
+ * restarted it from the issuing bar's close whenever the re-issue found no
+ * resting exit under its (id, from_entry): here the flat-armed legs were
+ * reconciled at the fill and the TP1 sibling's same-bar fill left the
+ * "Exit Short" re-issue with no pending twin to inherit from.
+ *
+ * Long twins mirror the shape on the same feed (see the tapes named in the
+ * family-Z ledger notes; the run function below takes either side).

+/*
+ * test_tv_fill_rounding.cpp — finding-446: a fill taken at a RAW BAR PRICE
+ * is TradingView's double-precision nearest-tick rounding of that print,
+ *   fill = floor(price / mintick + 0.5) * mintick     (no epsilon)
+ * and the feed itself is never quantized.
+ *
+ * Evidence: the NASDAQ:AAPL ohlcv-dump job tapes
+ * (pineforge-lab/evidence/ohlcv-dumps/NASDAQ-AAPL/jobs/<slice>/ohlcv-dump/
+ * tv_trades.csv, 61 slices, 521,162 fills). The strategy is
+ * process_orders_on_close=true, slippage 0, commission 0, so every
+ * "Price USD" is TV's fill of that bar's close, and the "Signal" column
+ * carries the raw bar as ts|open|high|low|close|volume at up to 10 dp.
+ * 24,582 fills sit on a half-cent close: 22,122 rounded UP and 2,460
+ * rounded DOWN — exactly the cases whose binary quotient lands just under
+ * the midpoint (228.765 / 0.01 = 22876.499999999996 -> 228.76) versus an
+ * exact one (214.385 / 0.01 = 21438.5 -> 214.39). The function above
+ * reproduces 24,582 / 24,582 (521,162 / 521,162 including on-grid closes)
+ * and 142,938 / 142,938 OANDA:EURUSD fills at tick 1e-5. Decimal half-up,
+ * float32, and any epsilon nudge (floor(r + 0.5 + 1e-6)) all miss the
+ * 2,460 down cases.
+ *
+ * The tables below are a static replay of that census (regenerated from the
+ * tapes by the fix author; nothing is read at test time): EVERY distinct
+ * midpoint-down value, a dozen midpoint-up values, and the two 4-dp prints.
+ *
+ * NDEBUG-PROOF: every assertion uses the returning CHECK macro (failure
+ * increments g_fail; main returns nonzero). bare assert() is never used.

+ * test_tv_money_long_margin_call_eth.cpp — round 10 family AB: TradingView's
+ * 10-significant-digit margin call on an EXPLICIT-qty margin-100 long, on the
+ * BINANCE:ETHUSDT.P@15 hard lane (the corpus probe
+ * anomaly-equity-mirror-strategy-equity-01; campaign notes
+ * log-20260905t213120z-d5f9e282 and the family AB pin note).
+ *
+ * The broker marks the position's required margin on money rounded to ten
+ * significant digits (3 decimals at >= 1e6) while the equity is exact. A 1x
+ * long whose free cash after the fill is smaller than the value's rounding
+ * residual at some bar path point (the post-fill points of the fill bar, then
+ * every bar's open / extremes in leg order / close) is liquidated one whole
+ * contract there, tagged "Margin call", at that raw path price.
+ *
+ * Fixtures are the registry's ETHUSDT.P 15-minute bars (lab bars, feed
+ * 27b62431096e) around three Monday 00:00Z signals; the quantities are the
+ * probe's round3(equity / close); the capitals are lab tv capital sweeps
+ * (scratchpad/r10/famAB/pins in pineforge-workflow, tapes famab-0421-c*,
+ * famab-0721-c*, famab-1124-c*; "c00020" = cost + 0.0002 of free cash):
+ *
+ *   04-21  Q 623.163 @1592.52 (00:15Z open == 00:00Z close). Residuals along
+ *          the path: 00:15Z low 1592.52 +0.00004, high 1613.8 -0.0004, close
+ *          -0.00048; 00:30Z open -0.00048, low 1606.17 +0.00029, high -0.00018,
+ *          close -0.00014. TV: cash 0.00013 (the probe's own ledger, E
+ *          992399.54089) / 0.0001 / 0.0002 -> 'Margin call' 1 @1606.17 on the
+ *          00:30Z bar, then 622.163 flattened @1613.78 (the 00:45Z open);
+ *          cash 0.0003 / 0.0004 / 0.0005 / 0.001 -> one 623.163 trade, no call.
+ *   07-21  Q 270.621 @3731.72. Residuals: fill bar high 3734.89 +0.00031, low
+ *          3709.27 +0.00033, close +0.00025; next bar open +0.00025, high
+ *          -0.00049, low 0, close +0.00016. TV: cash 0.0004 / 0.001 -> one
+ *          270.621 trade, no call. (cash 0.0001 / 0.0003: TV does not fill the
+ *          entry at all — family R's rounded-cost admission on a decimal tie,
+ *          round8/famR-eurusd, NOT part of this change; not asserted here.)
+ *   11-24  Q 356.701 @2778.39. Residuals: fill bar low 2761.38 +0.00002, high
+ *          2786.26 +0.00004, close -0.00003; next bar open -0.00004, low
+ *          -0.00002, high +0.00005, close -0.00002. TV: cash 0.00003 ->
+ *          'Margin call' 1 @2786.26 on the FILL bar (its high, after the low
+ *          passed with a residual under the cash), then 355.701 @2788.12; cash
+ *          0.0001 / 0.0003 / 0.001 -> one 356.701 trade. (cash 0.00001: TV drops
+ *          the entry — E 991054.4913999999 < the rounded cost 991054.4914,
+ *          family R's rule 2; not asserted here.)
+ *
+ * The probe's whole tape (24 TV rows) reproduces row for row once this event
+ * is in the ledger: the 7.61 USDT the engine used to book on 04-21 was the
+ * seed of every later quantity's divergence (25 vs 24 rows, weak 65.2 %).
+ *
+ * Scope controls: the trigger is scoped by tv_money_scope (a lot-stepped
+ * instrument whose lot is worth under one account unit; ETHUSDT.P at qty
+ * step 0.0001), so qty_step 0 keeps the exact arithmetic; the emulator
+ * switch turns it off.

+ * FL, rev, revb, revc, revd, revL, S1, S1f, S2, S3, pS) are replayed on the
+ * registry feed's bars (test_tv_money_precision_data.hpp, generated by
+ * gen_tapes_v2.py) and compared ROW FOR ROW — entry bar, side, fill price,
+ * quantity, exit bar, exit price, 'Margin call' vs close, net PnL. 202 tapes

+ * S100..S103, S307..S317 among them); the 1 the generator's independent
+ * predictor does not explain is the documented residual (revL L23: TV's
+ * one-unit entry fill when the entry leg fails with Q == |position| + 1.00)
+ * and is replayed for information only — it must never be silently
+ * promoted. test_tv_money_band.cpp replays the famr3 sweeps that pinned the

+ * test_zero_offset_trail_rides.cpp — round 10 family AC: the EXPLICIT
+ * trail_offset = 0 (or sub-tick) trailing exit is a zero-distance trailing
+ * stop on the raw running best once it is armed. A bar that opens past its
+ * activation is NOT automatically the one-shot fill the omitted-offset shape
+ * takes: whether that open fills or the trail rides from it is decided by the
+ * TICK GRID the open lands on (rule 3). Pinned with 76 `lab
+ * tv` tapes on NYSE:F 15m and NASDAQ:AAPL 15m (scratchpad/r10/famAC/pins,
+ * pins2, pins3, pins4, pins5; ledger log-20260905t214404z-57eb640d, its pins2
+ * supplement and the pins4/pins5 notes of 2026-09-05 23:2xZ),
+ * replayed here on the registry feed bars (`lab bars`, feeds 80f404ae85ef /
+ * ae2b03d3736f). The seed: boztilkiserhan-serhan1-wma-rsi-trailing-scalp on
+ * NYSE:F 15m re-issues strategy.exit(trail_points = close * 1.5% /
+ * syminfo.mintick, trail_offset = 0) on every bar; its long filled
+ * 2025-10-24 13:45Z @13.26 and TV exits at the 14:00Z open PRINT 13.49
+ * (O 13.485), where the round-7 open-as-level shortcut (fa8fd0e) floored
+ * 13.48 — one cent that re-rolled every later all-in placement.
+ *
+ * The rule, in the order TradingView applies it:
+ *   (1) ARMING. The trail arms at the first price that reaches its
+ *       activation: the placement bar's close (the running extreme restarts
+ *       there — round 9 family Z; the entry bar's high does NOT arm an exit
+ *       issued at that bar's close: p26 / p27), then each bar's raw open
+ *       (g1 / g1b: 12.255 does not arm a 12.26 activation), then the
+ *       tick-quantized path extremes. An exit issued ALONGSIDE the entry is
+ *       live on the entry bar itself and fires there (a1 / a2: 13.52, 13.50
+ *       at 13:45Z).
+ *   (2) OPEN AT / THROUGH THE LEVEL. Armed before the bar, level = best; an
+ *       open at or through it (long: open <= best) is a stop the open
+ *       filled — the OPEN PRINT, nearest-in-double like every gapped-through
+ *       print (13.485 -> 13.49, 9.465 -> 9.47, 9.485 -> 9.48, 9.665 -> 9.66,
+ *       13.915 -> 13.91, 10.075 -> 10.07), regardless of the bar's path
+ *       (high-first flat opens fill at the open, not at the high: 9.47 not
+ *       9.50, 9.57 not 9.62; short 9.27 not 9.25).
+ *   (3) OPEN BEYOND THE BEST. A favourable gap raises the best to the open
+ *       (arming it if it was dormant). TradingView places the fresh stop at
+ *       that open snapped DIRECTIONALLY to the tick grid (long floor, short
+ *       ceil) and tests it at once against the open's PRINT (the nearest
+ *       tick, floor(x / tick + 0.5) in doubles — bar_fill_price):
+ *         - print AT the stop (it rounds toward the stop side; an on-grid
+ *           open trivially): the exit fills at the open, a level fill booked
+ *           at that stop, whatever the bar's path — on-grid AAPL 05-12
+ *           211.05 (not the 211.26 high), 04-08 186.65, 09-03 237.18, 04-14

+# R4-D twin-parity ledger (repo-local CI fixture)
+
+Extracted from the root-approved deletion ledger for base `ab9714beccb62b796c122cf68986ec9e7dbf4a67`. This file is consumed directly by CI; it has no campaign-path dependency.
+
+## Appendix 5 — CHECK-parity unobservable literal ledger
+
+Each row is one base CHECK-family invocation that cannot be observed after the
+legacy owner is deleted. The checker validates the exact base source line and
+normalized CHECK text, and requires the named twin row to retain the public
+behavioural assertion. This appendix is intentionally per-literal rather than
+per-file: a broad replacement-test name is not evidence that a removed
+assertion survived.
