P3-S22.3 — RESEARCH M30 CONSTRUCTION REPAIR (additive namespace)

Session    : P3-S22.3 — RESEARCH M30 CONSTRUCTION REPAIR &
             POPULATION REDERIVATION
Status     : COMPLETE (research-only; corrected pipeline implemented + verified)
Policy     : docs/CODE_VERIFICATION_AND_SILENT_BUG_POLICY_v1.md
Disposable : YES — this namespace is the corrected RESEARCH construction,
             its independent oracle, deterministic replay and evidence. It is
             NOT part of production MQL5, FEATURE_CONTRACT, labels, or the
             frozen P3-S16..P3-S22 artifacts (those are unchanged).

What this namespace is

The historical research M30 gate series used an index-pair resample of the M15 feed (2 x M15 per M30 via spec_tests_engine2_gates.m30_from_m15). That construction drifts from the runtime (broker UTC-grid) M30 at session/data, weekend, holiday and DST gaps (ADJ-2, established in P3-S22.1/P3-S22.2). This namespace implements the corrected research M30 construction on fixed UTC 30-minute buckets, an independent oracle, the deterministic replay of the Candidate Setup population, and the full regression/mutation/agreement suite.

No production MQL5, F1/F2/F3/F4 contract, P3-S16 label, TP/SL/horizon, FEATURE_CONTRACT, or frozen historical artifact is modified. Nothing here trains, calibrates, or trades.

Modules

File	Role
s223_common.py	frozen input loaders + corrected UTC M30 construction + as-of gate + invariant
s223_partB_oracle.py	corrected construction (Part B) + independent oracle + 100% agreement (Part C)
s223_partDR_mutation.py	Part D: 12 regression scenarios + 6 mutation tests
s223_run_main.py	Parts A..J: invariant, construction, oracle, regression, baseline repro (694/686), corrected replay (707), population/label impact, audit, comparison
s223_run_repro.py	reproducibility runner (2 runs, byte-identical substantive outputs)

Key results (single source: output/s223_main_pipeline.json)

• PART A invariant: M30_open = floor(M15_open/1800)*1800 verified on all 100,764 UTC buckets; 0 mismatches.
• PART B corrected construction: 100,764 M30 bars; gate nonzero 180,774/197,032.
• PART C oracle agreement: corrected vs independent oracle 100% on timestamps / OHLC / dirs / gate.
• PART D: 12/12 regression invariants hold; 6/6 mutations detected.
• PART E frozen baseline: committed gates reproduce 694 created / 686 in-scope / 0 per-bar mismatch (frozen contract).
• PART F corrected replay: corrected gates -> 717 created / 707 in-scope; shared 484, old-only 202, corrected-only 223 (matches P3-S22.2 validated).
• PART G: common 484 rows identical-label; 202 previously-absent; 223 newly-available; UNRESOLVED corrected 28, AMBIGUOUS 6.
• PART H audit: old 686 (594+92); corrected 707 (610+97); total==leads+followons.
• PART I dataset: M30 gate diff 38,399 full / 37,651 scope.
• PART J machine-repro: oracle_100pct=true, mutation_all_detected=true, deterministic=true.

Design boundaries

• The corrected construction is new and additive; it never rewrites the committed p3_s17r1_gate_series_cache.npz index-pair m30.
• The independent oracle uses a distinct accumulation path (oracle_clock_m30) + a searchsorted as-of (distinct from the np.searchsorted in s_common.as_io_m30_gate implementation detail, but same rule).
• All tests use disposable copies; mutation faults are never committed to the real pipeline.
• No timing/window/tolerance tuning; all constants come from the frozen research contracts (P3-S16/P3-S17/P3-S18).
