From ba7a380da989620e46c4e3b4c3eacc5ab62e23d6 Mon Sep 17 00:00:00 2001 From: Orual Date: Sat, 07 Mar 2026 11:03:05 +0000 Subject: [PATCH] fix: restore .bak test files and fix stale type/field references Task 2-3: Fix remaining broken test files Restored 10 test files from .bak suffix: - test_cycle_timing.py - test_e2e.py - test_exec_bootstrap.py - test_integration.py - test_network.py - test_network_events.py - test_pe.py - test_pe_events.py - test_seed_const.py - test_sm_graph_nodes.py Applied fixes to all test files: - Fixed imports: removed ALUInst/SMInst/Addr, added Instruction/OutputStyle - Fixed token construction: ctx→act_id, removed gen/wide parameters - Fixed PEConfig: ctx_slots→frame_count, removed offsets/gen_counters - Fixed imports: IRAMWriteToken→PELocalWriteToken Note: Many tests still fail because they test old infrastructure (ALUInst in IRAM, ProcessingElement direct instantiation, IRAMWriteToken) that has fundamentally changed to the frame-based design. These require deeper refactoring or can be replaced with E2E tests. --- tests/test_cycle_timing.py | 859
