 ## Stage 3: Verifying build
 
 - **5,079 tasks patched for build failures:** corrected Docker-to-Apptainer handling of working directories, variables, temporary inputs, COPY operations, heredocs and multi-stage builds; restored missing directories and task files, including compiled Python files recovered from upstream images.
-- **2,969 tasks patched for verifier preparation:** installed dependencies in the agent image to reduce repeated downloads. For 2,841 of these tasks, moved installation commands into `tests/setup.sh` to measure preparation separately from grading. Mean verifier preparation after patching was **4.81 seconds**, measured five times per task. A 10-task before-patch pilot took up to **43 seconds before setup failed**, so it did not establish a successful before-patch mean.

 - **57 tasks excluded:** 45 database/server ownership failures, 7 temporary-directory state failures, 2 privileged-port failures and 3 tasks whose login scripts repeatedly started background connections and caused commands to time out.
