From fbd532a3c7a07a98d15fbda856fdf58864405fdb Mon Sep 17 00:00:00 2001 From: JeffreyChen Date: Mon, 25 May 2026 14:34:39 +0800 Subject: [PATCH 1/5] Add 37 utility modules covering web APIs, security, AI/workflow, i18n, backend, governance, emerging tech Modules added under je_web_runner/utils/: Web platform: popover_assert, cookie_store_api, speculation_rules, web_locks, storage_buckets, hydration_streaming. Performance & security: memory_pressure_emulate, third_party_block_test, bundle_diff_pr, prompt_injection_scanner, cors_matrix, oauth_pkce_replay, cookie_chips_audit, sbom_diff, webhook_signature_verify. AI/workflow & governance/DevX: failure_auto_tag, test_self_describe, pr_title_generator, action_refactor_suggester, test_roi_scorer, pre_merge_gate_dsl, commit_msg_trigger, flakiness_graveyard, test_blame_owner. i18n/a11y: rtl_layout_verify, dst_boundary_test, number_currency_locale, wcag22_touch_target. Backend integration: graphql_n_plus_1, mq_assert, grpc_streaming_assert. Emerging tech: webgpu_pixel_verify, webhid_mock, webusb_mock, webserial_mock, webcodecs_assert, speech_api_assert. Each module ships matching unit tests; all 642 new test cases pass. --- CLAUDE.md | 39 ++- .../action_refactor_suggester/__init__.py | 0 .../action_refactor_suggester/suggest.py | 174 +++++++++++++
