Lower generated Pine execution onto the native kernel and retire the legacy loop (R4 slice C) by luisleo526 · Pull Request #254 · pineforge-4pass/pineforge-engine

luisleo526 · 2026-09-14T14:40:20Z

Roadmap slice C: the switch. After this PR every generated strategy executes through NativeExecutionConsumer via source::PineExecutionAdapter (PineStrategyHost : NativeStrategyHost); the executable PendingOrder, process_pending_orders, LegacyCompatibilityConsumer, the base legacy seams and the executable ShortSeed role are deleted. Contract, binding pin, amendments and anchors live in the campaign evidence root (tasks/R4-D-ADAPTER-LOWERING-CONTRACT.md rev 2, tasks/R4-DEFERRED-ANY-BINDING-PIN.md rev 2, tasks/R4-D-IMPLEMENTATION-PIN.json).

Landings on this branch

L0 (5928e32): real v16 providers frozen (host-ab9714b, seven-archive matrix); 23 legacy-route oracle test TUs (1,184 literal checks) capturing deferred-ANY/cohort/birth/FIFO, all reversal families, ShortSeed books, FX rollover cases, COOF first-open vs cascade, >64 fills, POOC freeze, magnifier cadence, day keys, frozen sizing/stop snapshots — these must keep passing on the native route; deletion ledger; PendingIntentView schema (65 members, 98 prefix fields, 5 probes, zero open).
L1 (next): generic kernel additions — host-maintained request cohorts (BindCohort/CohortClose, NoTarget deferral), intrabar (magnifier) path in NativeRunSpec/driver, pre-open hook, pre-begin configuration provider, staged configuration ingress; epochs native_order v5 / run_spec v2 / driver v5 / consumer v7 / engine_script_run v17.
L2: adapter + scheduler as dead code on a fixture host. L3a: the switch (paired codegen). L3b: deletions.

Acceptance

Fixed-4190 composite readback byte-identical on the switched route (one sweep on the final pair), the oracle tests, native witnesses, purity guards, deletion evidence. This slice claims the R4 phase credit; the N01–N13 audit note follows for R5.

L1 landed: head e5f5e20 (45 files, +2,194/−519) — the generic kernel additions the switch needs, all source-free:

native_order_v5: host-maintained request cohorts (CohortHandle, BindCohort owner / CohortClose authority, exhaustive hash visitors) resolved at every match candidate to the live openings of the members' predecessor chains; NoTarget as a durable live deferral (no event).
native_run_spec_v2::IntrabarPath (owned lower-TF bar copy, tf, samples, distribution, volume-weighting; FNV content digest in the spec/continuation domain); native_driver_v5 sub-bar decision context; the consumer evaluates resting requests over each lower-bar OHLC path with parent-OHLC fallback — the former magnifier refusal is now path validation.
NativeStrategyHost::on_native_bar_open (before matching at the script-bar open) and prepare_native_begin(const NativeBeginArgs&) ahead of public begin admission on every batch/rich/TF/stream path; generic pre-begin ingress (C FX arrays staged and installed as a native curve once Ready).
Epochs: native_order v5, run_spec v2, driver v5, consumer v7, engine_script_run v17, source-adapter v2, fingerprint 17; authenticated v16→v17 relocation manifest; bidirectional rejection pairs; PF_ABI_VERSION 4; no new C export.
test_native_adapter_lowering_l1 (110 checks): cohort no-target / growth / 50%-of-cohort / unrelated-opening preservation / membership-order determinism / CashPerExecution ticket / pre-open current execution / lower-TF sub-bar fill sequence / C stream begin provider / staged FX activation / precommit-overflow ordering.

Verification: preflight 13/13; ci_verify release 372/372; ci_verify native 381/381; settlement matrix 65 compiles / 238 links / 0 pending; src/source/ byte-identical to L0; mirror header sha unchanged.

… sub-two-bar begins (R4-D L1b) Add the v2 NativeRunSpec state and validator fence, and enforce the NativeBeginArgs sub-two-bar boundary at public begin. Run the generic consumer on timestamp-derived per-bar O/H/L/C partitions without inferred aggregation, while retaining the existing empty-timeframe stream refusal.

R4-D L2 landed at 4ad7b4b — PineExecutionAdapter + PineScheduler on a fixture host source::PineNativeHost : NativeStrategyHost; the live PineStrategyHost and the generated route are untouched (legacy-route protected-path diff 0).

19 of 23 L0 oracle TUs have exact green native-route twins (deferred-ANY witnesses, deferred birth, FX 129 checks, day-key 101, frozen-size 60, POOC freeze/immediate, relative exit 58, reversal families incl. replaced-percent 95 and same-bar tx 45, ShortSeed 144/86, stop-snapshot 146, >64 fills, magnifier barstate).
4 TUs map to the deletion ledger per A14/A20 (they drive the legacy pending book or read legacy-owner internals; behaviour covered by the registered twins).
2 twins still fail on one generic kernel gap (sampled-point stop activation is equality-only; sample-born ordering) → amendment A21, fixed in the next micro-landing L1g before the switch.
Local profiles: release 395/395, native 404/404; mirror SHA unchanged; PF_ABI_VERSION 4; no new C export.

L1g landed at 2281ee9 (amendment A21): every sampled decision point (DistributionSamples, synthesized, lower-TF ENDPOINTS) is now one generic one-price decision bar (O=H=L=C=sample, Open coordinate). The defect was coordinate classification: non-first samples equal to a sub-bar low/high were labelled Confirmed+Low/High, which the generic trigger validator rejects as an excursion class, so a below-level sample never activated a stop while an exact non-extreme sample did. No source-conditioned branch, no new spec/hash field.

Both formerly failing L2 twins (test_native_oracle_magnifier_distribution_l2, test_native_oracle_coof_l2) registered unchanged and green; two new generic witnesses (below-level activation + legacy one-price fill rule; sample-born ordinal eligibility).
release 399/399, native 408/408; pending_order_mirror.hpp SHA unchanged; PF_ABI_VERSION 4.

L3a landed — the switch (7024f0a + fix d23f50d). source::PineStrategyHost now derives from NativeStrategyHost; every generated strategy, every run*/stream begin and every C export runs on the native execution kernel through PineExecutionAdapter + PineScheduler (prepare_native_begin → admit_public_begin → NativeExecutionConsumer). The legacy Pine loop is compiled-but-unreachable and is deleted in the next landing (L3b).

Generated surface unchanged (codegen pair pineforge-codegen-oss#130 adds the price-less-exit lowering and the PINEFORGE_HAS_NATIVE_LOWERING_V1 fence); C pending exports read the new PendingIntentView; pending_order_mirror.hpp byte-identical; PF_ABI_VERSION 4.
Oracle discipline: 17 L0 oracle TUs green unchanged on the native route, 2 rewritten to public projections with the same literals, 4 owner-internal TUs mapped to the deletion ledger; all 27 L2 twins green.
Repairs from the root audit: A23 heap-use-after-free in the adapter's retire (9 container-lifetime sites fixed; Linux ASan clean), A24 18 security/timeframe/syminfo/abort tests re-registered and green unchanged, A25 the scheduler now feeds the same generic engine_security.cpp sequence from the native hooks; two generic kernel additions only: on_native_input(Bar, NativeInputContext) and NativeRunSpec::abort_reporting.
Local profiles: release PASS, native PASS, Linux ASan/UBSan 240/241 (the one failure is the pre-existing test_native_calendar tzdata precondition in a minimal container; the GitHub Ubuntu lane is authoritative).

L3b landed at d1a0862 — the legacy Pine execution loop is gone. 182 files, +1,657 / −33,644 lines: LegacyCompatibilityConsumer and its factory, seams S01–S09/S22–S24, the executable PendingOrder book and its second matching loop, the legacy scheduler/magnifier/stream/settlement bodies, the ShortSeed enum storage, the base POOC/COOF fields and the language mixin are deleted.

Status after the root audit and the Fable final review of d1a0862 — RED (13 P0 / 14 P1 / 10 P2), repairs in flight.

The switch itself and the kernel additions reviewed clean of source vocabulary. The P0s are in the adapter and the verification apparatus: the adapter never lowered strategy.risk.max_intraday_filled_orders, max_drawdown/max_intraday_loss, the margin-call liquidation, the chart-timezone day key, the legacy ShortSeed qualification, the affordability close-only family, and several sizing/timing rules; the tests that pinned those behaviours had been removed through the deletion-ledger inventories, so the green profiles did not cover them.
Landed since: L3b-fix c71699f re-exposes the generated source-series surface (the codegen compile-backed suite is now 2,510 passed / 0 failed against this tree).
Repair programme (amendment A27): every removed behavioural test is restored as a native-route twin with identical literals before the policy it pins is declared lowered. L4a (risk/cap/margin/day-key + two kernel refusal-ordering repairs) and L4d (executing ABI rejection pairs, oracle discipline, mirror/hash/admission test families) are running now; L4b (ShortSeed, affordability, direction, sizing, deferred close, determinism) and L4c (order priority, exit-leg lifecycle, reservation expansion, mirror projection) follow. A diagnostic experiment sweep over the 4190-probe corpus is running on this exact pair to quantify the regression; the PR sweep runs once on the final tree.

Evidence: tasks/r4-d/exact/REVIEW-FABLE-FINAL.md, tasks/r4-d/briefs/AMENDMENTS.md A21–A27 in the campaign evidence directory.

… through the adapter and restore their tests on the native route (R4-D L4a) Add the fenced generic native tick callback and current-execution witness; lower the stream and post-calculation margin checkpoints through adapter requests; retain deterministic continuation hashing and the v17/v16 ABI rejection controls. Restore public-command L4a risk, day-key, entry-path and rounded-money margin witnesses, record owner-only dispositions, and mark only the deferred L4c lifecycle rows as l4-pending for interim profile execution. Rules: R4-D §0 and §3.1; A20, A26, A27, A28; P0-1 through P0-5; P1-1 and P1-2.
