B2R2 LowUIR IR Lifting for Semantic Binary Analysis

Module

Web

Status

IMPLEMENTED

Description

B2R2 LowUIR adapter for intermediate representation lifting, bounded lifter pool with ISA warm preload, and Valkey-backed function-level IR cache with PostgreSQL persistence for deterministic semantic fingerprints.

Implementation Details

  • Feature directory: src/Web/StellaOps.Web/src/app/features/binary-index/
  • Components:
    • binary-index-ops (src/Web/StellaOps.Web/src/app/features/binary-index/binary-index-ops.component.ts)
    • patch-map (src/Web/StellaOps.Web/src/app/features/binary-index/patch-map.component.ts)
  • Source: SPRINT_20260112_004_BINIDX_b2r2_lowuir_perf_cache.md

E2E Test Plan

  • Setup:
    • Log in with a user that has appropriate permissions
    • Navigate to /analyze/patch-map
    • Ensure test data exists (scanned artifacts, SBOM data, or seed data as needed)
  • Core verification:
    • Verify the component renders correctly with sample data
    • Verify interactive elements respond to user input
    • Verify data is fetched and displayed from the correct API endpoints
  • Edge cases:
    • Verify graceful handling when backend API is unavailable (error state)
    • Verify responsive layout at different viewport sizes
    • Verify accessibility (keyboard navigation, screen reader labels, ARIA attributes)
