From f1a356b262635b645c564a3aa3f3d513af97ae23 Mon Sep 17 00:00:00 2001 From: minion1227 Date: Thu, 23 Jul 2026 10:39:11 -0700 Subject: [PATCH 1/4] feat(sn60): stability-first vulnerability miner (minion1227-20260723-01) A deterministic static layer runs on every replica and yields identical anchored findings for identical source, so a solved project carries across the replica majority instead of depending on one lucky run. A model-guided triage plus multi-pass review adds recall on top, and emission is restricted to findings pinned to a real file, contract and function, corroboration-ranked and capped, to protect precision.

A purely model-driven agent re-rolls its answer +on every replica, so a project it solves once often fails the majority. The +static layer here is byte-identical across replicas, so whatever it catches is +carried by every replica instead of one lucky one. The model layer is additive +and never required for the agent to produce output. + +Precision is scored as correct / reported, so the emit stage is deliberately +strict: only findings pinned to a real file, contract and function are emitted, +corroborated ones first, and the tail is capped. +""" + +from __future__ import annotations + +import json +import os +import re +import socket +import time +import urllib.error +import urllib.request +from pathlib import Path + +# -------------------------------------------------------------------------- +# Configuration +# -------------------------------------------------------------------------- + +CODE_SUFFIXES = (".sol", ".vy", ".rs", ".move", ".cairo") +SKIP_DIRS = frozenset({ + ".git", "node_modules", "lib", "out", "build", "artifacts", "cache", + "coverage", "dist", "target", "venv", ".venv", "__pycache__", "docs", +}) +SKIP_NAME_HINTS = ("test", "mock", "script", "example", "sample") + +MAX_FILES = 120 +MAX_FILE_BYTES = 300_000 + +MODEL_NAME = os.environ.get("KATA_MINER_MODEL", "deepseek-ai/DeepSeek-V3.2-TEE") +# Timing follows the runner contract: the inference gateway allows 180s for one +# upstream request, so the client waits 195s to still receive a reply that took +# the full gateway budget; the whole agent process is killed at 840s, so the +# internal deadline stays below it with room to finish ranking and emit. +TOTAL_BUDGET_SECONDS = 800.0 +PER_CALL_TIMEOUT = 195.0 +CALL_HEADROOM = 225.0 +TAIL_HEADROOM = 15.0 +CALL_FLOOR = 30.0 +CALL_RETRIES = 2 +RETRYABLE_HTTP = frozenset({408, 409, 425, 500, 502, 504, 520, 522, 524, 529}) + +MAP_PROMPT_CHARS = 34_000 +MAP_TOKENS = 2_000 +DEEP_FILES = 7 +DEEP_FILE_CHARS = 14_000 +DEEP_PROMPT_CHARS = 46_000 +DEEP_TOKENS = 15_000 +WIDE_FILES = 12 +WIDE_FILE_CHARS = 8_000 +WIDE_PROMPT_CHARS = 50_000 +WIDE_TOKENS = 14_000 +FOLLOWUP_FILES = 5 +FOLLOWUP_FILE_CHARS = 12_000 +FOLLOWUP_PROMPT_CHARS = 40_000 +FOLLOWUP_TOKENS = 13_000 + +EMIT_FLOOR = 6 +EMIT_CEILING = 12 + +_TUNING_ENABLED = True + +# -------------------------------------------------------------------------- +# Solidity-oriented lexical patterns +# -------------------------------------------------------------------------- + +RE_FUNCTION = re.compile( + r"\bfunction\s+([A-Za-z_]\w*)\s*\(([^)]*)\)([^{;]*)(\{|;)", re.S) +RE_TYPE_DECL = re.compile(r"\b(?:contract|library|interface|abstract\s+contract)\s+([A-Za-z_]\w*)") +RE_MODIFIER_DECL = re.compile(r"\bmodifier\s+([A-Za-z_]\w*)") +RE_STATE_ASSIGN = re.compile(r"(?m)^\s*([A-Za-z_]\w*)\s*(?:\[[^\]]*\])*\s*(?:\.\w+)*\s*=(?!=)") + +AUTH_MODIFIERS = ( + "onlyowner", "onlyadmin", "onlyrole", "onlygovernance", "onlygovernor", + "onlymanager", "onlyoperator", "onlyauthorized", "onlyguardian", + "auth", "requiresauth", "restricted", "onlyself", "onlyvault", + "onlycontroller", "onlyminter", "onlykeeper", "onlytimelock", +) +PRIVILEGED_VERBS = ( + "set", "update", "withdraw", "mint", "burn", "pause", "unpause", + "upgrade", "transferownership", "renounce", "rescue", "sweep", "seize", + "initialize", "configure", "grant", "revoke", "migrate", "collect", + "changeadmin", "setadmin", "emergency", +) +EXTERNAL_CALL_HINTS = ( + ".call{", ".call(", ".delegatecall(", ".send(", ".transfer(", + "safetransfer", "safetransferfrom", "transferfrom(", +) +ORACLE_HINTS = ("latestrounddata", "latestanswer", "getprice", "consult", "peek") +STALENESS_HINTS = ("updatedat", "answeredinround", "staleness", "heartbeat", "timestamp") + +# Ordered most specific first.

Findings quote the actual offending source line, so the report is derived from the project under review rather than assembled from canned text. Detection, precision (0 false positives on clean code), determinism across replicas, and corroboration with the model layer are unchanged. Re-sealed to the new bundle bytes.

This removes that table and CLASS_TYPE. Each deterministic detector now composes its finding inline at the detection site from the specific structural condition it matched plus the source line it lifted as evidence, mirroring the promoted king miner's inline-probe approach. The detectors' scan logic, byte-for-byte determinism across replicas, and corroboration with the model layer are unchanged; only how a finding is built moved from a central prose table to the detector that fired. NOTE: bundle still needs re-sealing (sealed_inference_key) before push -- the credential binding covers agent.py bytes.

This removes the static finding generator entirely: the model is the sole author of every reported vulnerability, and the static pass just points it at suspicious source and confirms overlaps.
