Multi-SWE v1: reinstall the upstream test harness from /tests before grading and add the timeout sentence

All 1,872 kept tasks adjusted from multiswe_v1 at d6372d8 with patch.py --release-repair. Stages 2 and 3 have not yet been run on the adjusted tasks.

 - **1. Build and setup: 1,872 changed, 8 archived.** Archived 8 tasks: 4 Nuxt setup OOMs, 1 Checkstyle setup failure and 3 Mockito image-build failures due to Maven dependency downloads.
 - **2. Reference solution (reward 1): 62 changed, 269 archived.** Increased memory from 4 to 8 GiB for 58 tasks to prevent reference-solution OOMs. Restored missing Java regression-test inputs in 3 tasks; all 3 now pass reference and no-op validation. Fixed passing-test detection in 1 task so a missing line break no longer hides a passing test. Archived 180 tasks whose reference solution returned 0, 53 whose verifier could not execute successfully because of dependency, environment or test-execution errors, 32 that hit the memory limit with an 8 GiB configuration, and 4 whose verifier exceeded 30 minutes.
 - **3. No-op baseline (reward 0): 0 changed, 37 archived.** Archived 29 tasks whose unchanged baseline scored 1 and 8 tasks that hit the memory limit at 8 GiB. All 8 had one passing reference result, but 4 also had attempts fail from OOM, so we archived them as not reliably solvable. Manually approved 422 false positives from the no-op checker, which could not confirm verifier execution; the corresponding reference solutions passed.
-- **4. Rule-based checks: 1,871 changed, 0 archived.** Removed later or unrelated Git history from 1,871 kept tasks to prevent access to potential future fixes. Also cleared reflogs and unreachable objects and normalized tracked-file timestamps.
+- **4. Rule-based checks: 1,872 changed, 0 archived.** Removed later or unrelated Git history from 1,871 kept tasks to prevent access to potential future fixes. Also cleared reflogs and unreachable objects and normalized tracked-file timestamps. Adjusted all 1,872 kept tasks after validation: the verifier now reinstalls the upstream test scripts from `/tests` before grading, because the copies in `/home` could be edited by the agent, and the instruction ends with the timeout sentence. Stages 2 and 3 have not yet been run on the adjusted tasks.
 
 The strict check for exact solution-file copies in the agent environment passed for all 70 checked tasks selected to keep. The remaining 1,802 kept tasks have not completed this check.
