Summary
During the Daily CLI Performance run (§30374053812), make bench-performance failed on BenchmarkCompileMCPWorkflow (in pkg/workflow/compiler_performance_benchmark_test.go). All other 8 benchmarks compiled and ran successfully within performance baselines, so this is not a performance regression — it is a broken test fixture.
Error
--- FAIL: BenchmarkCompileMCPWorkflow
compiler_performance_benchmark_test.go:164: warm-up compile failed: /tmp/bench-mcp.../mcp.md:1:1: error: Validation failed for field 'tools.cache-memory.key'
Value: pr-${{ github.run_id }}
Reason: cache key must not reference github.run_id — every run would write to a unique cache slot, preventing cross-run cache restoration
The test fixture at line 142 of pkg/workflow/compiler_performance_benchmark_test.go sets:
key: pr-${{ github.run_id }}
This is now rejected by the compiler's cache-key validation (introduced separately), which requires cache keys to omit github.run_id since it's appended automatically.
Suggested Fix
Update the fixture's cache-memory key to something like pr-${{ env.GH_AW_WORKFLOW_ID_SANITIZED }} so the benchmark warm-up compile succeeds.
Secondary Issue: corrupted benchmark history
The repo-memory file benchmark_history.jsonl (used for tracking daily performance trends) was found corrupted — multiple prior runs' JSON objects had been concatenated onto a single malformed line, preventing all historical trend comparisons. All entries prior to today (2026-07-28) were unrecoverable and have been discarded; the file now contains only today's baseline entry. Trend/regression detection will resume once a few more days of clean data accumulate. This may indicate a bug in how a previous run appended to the file (e.g., missing trailing newline before append).
