From 4d5fa6a9d18c97f88c67c7c0a84f4a942b853f7f Mon Sep 17 00:00:00 2001 From: HAL9000 Date: Thu, 7 May 2026 17:23:23 +0000 Subject: [PATCH 1/7] feat(acms): implement budget enforcement for max_file_size and max_total_size constraints Add ACMS BudgetEnforcer dataclass with per-file (max_file_size) and aggregate (max_total_size) constraint enforcement. Includes: - BudgetEnforcer: core enforcer with add_file(), get_assembled_context(), get_violations(), reset() methods and defensive-copy returns - BudgetViolation: structured violation reporting with filename, file_size, limit, and clear actionable messages (error for max_file_size, warning for max_total_size) - ContextFile: size tracking with automatic byte-size calculation from UTF-8 Also updates src/cleveragents/acms/__init__.py to export budget enforcement classes alongside existing UKO vocabulary exports. Comprehensive BDD test coverage: 11 Behave scenarios covering inclusion, exclusion, boundary conditions, cumulative budget cutoff, ordering, metadata reporting, empty files, and multi-byte UTF-8 measurement. Robot Framework integration tests with helper module.
