docs(stress-tests): M3.3 Phase A — calibration data collection Issue #46 (Phase A only — Phase B human rating still pending, issue stays open). Adds the data-collection half of the calibration milestone: - scripts/calibration_runner.sh — runs 20 fixed balanced-depth queries across 4 categories (factual, comparative, contradiction-prone, scope-edge), 5 each, capturing per-run logs to docs/stress-tests/M3.3-runs/. - scripts/calibration_collect.py — loads every persisted ResearchResult under ~/.marchwarden/traces/*.result.json and emits a markdown rating worksheet with one row per run. Recovers question text from each trace's start event and category from the run-log filename. - docs/stress-tests/M3.3-rating-worksheet.md — 22 runs (20 calibration + caffeine smoke + M3.2 multi-axis), with empty actual_rating columns for the human-in-the-loop scoring step. - docs/stress-tests/M3.3-runs/*.log — runtime logs from the calibration runner, kept as provenance. Gitignore updated with an exception carving stress-test logs out of the global *.log ignore. Note: M3.1's 4 runs predate #54 (full result persistence) and so are unrecoverable to the worksheet — only post-#54 runs have a result.json sibling. 22 rateable runs is still within the milestone target of 20–30. Phases B (human rating) and C (analysis + rubric + wiki update) follow in a later session. This issue stays open until both are done.

╭─────────────────────────────────── Answer ───────────────────────────────────╮
│ The relationship between red wine and cardiovascular health is nuanced and │
│ contested. Historically, observational studies found that moderate drinkers │
│ (at least one drink per day) were 30–40% less likely to die from │
│ cardiovascular disease compared to non-drinkers, a pattern sometimes called │
│ the 'J-shaped mortality curve' [NYT/AHA]. Red wine specifically contains │
│ polyphenols (including flavonoids and resveratrol) that may inhibit LDL │
│ oxidation, prevent endothelial dysfunction, raise HDL cholesterol, and │
│ decrease fibrinogen concentrations [Circulation Research; PMC6804046]. │
│ However, no study has established a direct cause-and-effect link between red │
│ wine consumption and improved heart health [AHA]. More recent analyses │
│ suggest the apparent benefit may reflect confounding factors—moderate │
│ drinkers may have healthier lifestyles overall—and methodological flaws such │
│ as including former drinkers (who quit due to illness) in the abstainer │
│ group [NYT; Three Spirit]. The 'French Paradox,' which popularized the red │
│ wine-heart health hypothesis, is now being critically re-examined as a │
│ public health myth [ResearchGate]. Major health organizations, including the │
│ American Heart Association, do not recommend starting to drink red wine for │
│ heart benefit, and current evidence does not support a causal protective │
│ effect of alcohol on the heart. │
