Run-close forensics: the postmortem the harness writes about itself

Build lab (Module 14, L14.5): every run closes with a six-section postmortem whose claims cite events. The generated postmortem has 0 citation problems and exits 0. Happened is 4 lines, under a cap of 5. The run cost 250 cents. The most expensive event is seq 43 at 90 cents, covered by decision d-search. Search was retried 3 times at seq 41-43, the same retries he-l84's trace records. Walking every event makes 15 lines, past the cap. In a four-sentence sample, index 2 is the uncited claim. The Google SRE Book's postmortem habit (chapter 15, 2016) is the published precedent for writing the incident down. The Tuesday trace is a synthetic illustration. Seed 0, no model call.
