Port the 8 audit-gap fns to Rust (name-preserving): _ms_core, _now_iso, promote_entry, compute_fama, compute_drift_velocity, compute_drift_direction, pre_commit_gate, pre_commit_gate_entry. The scoring surface delegates to memory_scoring (path dep — the authoritative kernel since its Python oracle was retired); the new decision kernels live in src/rust/drift_core while the sqlite IO stays in the facade (RUNE_DRIFT_CORE pin, dcore_loader seam, doc-envelope FFI, Python-typed JSON output: int/float split preserved). Audit 3/11 PARTIAL -> 12/12 FULL RUST. 30-row frozen truth (dc_freeze_seams rig, shared harness, gen+verify byte-identical x3), Rust battery 3/3 with the truth embedded via include_str!, live parity 30 frozen + 600 fuzz + 11 dual-mode facade rows failures=0, clippy -D warnings 0, fmt clean, pytest both pins 41 passed/4 skipped (drift-files test_211d_g failure verified pre-existing on the stashed base), ruff clean.

"""gen_drift_core_truth.py — factory wave GAP truth for drift_core.
|
|
|
|
Freezes the oracle behavior of the 8 audit-gap functions (dichotomy wave
|
|
#2479: _ms_core, _now_iso, promote_entry, compute_fama,
|
|
compute_drift_velocity, compute_drift_direction, pre_commit_gate,
|
|
pre_commit_gate_entry) plus scoring-surface regression rows (compute_value,
|
|
check_promotion_eligibility) through the SHARED harness
|
|
(scripts/freeze_truth.py — one law).
|
|
|
|
Runs under the freeze rig (scripts/dc_freeze_seams/sitecustomize.py —
|
|
PYTHONPATH-imported by BOTH this generator and --verify): pinned floor
|
|
(RUNE_DRIFT_CORE=python), frozen clock (RUNE_FROZEN_NOW reaches _now_iso
|
|
and the velocity cutoff through the harness's module-datetime patch),
|
|
hermetic per-row scratch store, embeddings off, and the db-carrying seams
|
|
(promote/fama/velocity/direction/gate) that drive the REAL oracle fns with
|
|
JSON-safe shapes. The memory_scoring kernel is intentionally LIVE (its
|
|
Python oracle is retired and raises — determinism requires the built .so;
|
|
the rig fails loudly when it is missing).
|
|
|
|
Run (from the repo root, under the sqlite-vec venv):
|
|
PYTHONHASHSEED=0 PYTHONPATH=scripts/dc_freeze_seams:src \
|
|
~/.venvs/memory/bin/python3 scripts/gen_drift_core_truth.py
|
|
|
|
Verify (byte-identical, same rig):
|
|
PYTHONHASHSEED=0 PYTHONPATH=scripts/dc_freeze_seams:src \
|
|
~/.venvs/memory/bin/python3 scripts/freeze_truth.py --verify \
|
|
src/rust/drift_core/frozen_truth.json \
|
|
--module rune.drift_core
|
|
|
|
Case map (every gap branch):
|
|
* _now_iso — None (frozen clock) + passthrough.
|
|
* _ms_core — probe contract True under the rig (kernel live).
|
|
* compute_value — no-goals + goals rows (ms-kernel regression).
|
|
* check_promotion_eligibility — eligible tuple row.
|
|
* pre_commit_gate_entry — short / refusal / well-formed critics.
|
|
* dc_freeze_gate — the empty oracle body (None → null).
|
|
* dc_freeze_promote — not-found / already-rock / ineligible-low-wash /
|
|
washable→established / established→rock /
|
|
unknown-status→established; `after` pins the UPDATE.
|
|
* dc_freeze_fama — empty ids / all-valid / mixed / missing rows /
|
|
inactive / null-wash+established.
|
|
* dc_freeze_velocity — inside+outside window / over-threshold alert /
|
|
days=0 (max(1,·) floor) / integral 2.0 rounding.
|
|
* dc_freeze_direction — stable / drifting / empty store / rock-only.
