## Reach
- followers: 2095

- posts_total: 1550
- posts_observed: 1
- posts_per_day: 3.355

## Engagement
- status: peak_post_only
- peak_post_engagement_rate: 0.06778
- best_post_interactions: 142
- measurement_source: x_post_interactions
- measurement_formula: interactions on one post — likes, or likes + reposts + replies depending on the discovery path (the two are not distinguishable in the stored data)
- comparable_pool: peak_interactions
- status_note: We have only the single best observed post, so no mean exists. peak_post_engagement_rate is an UPPER BOUND, systematically higher than an average — never compare it against an average rate.
- unit_note: engagement_rate and peak_post_engagement_rate are ratios (0-1); avg_interactions_per_post and best_post_interactions are absolute counts. Read status before reading any number: a null rate has several different causes and status says which one applies here.

## Evidence
- [x_tetsuo_cpp#8f7188fa] The Anthropic version of this ad shows an unemployed Chip Engineer scrolling LinkedIn Jobs and eating a can of baked beans while Mythos is running in the foreground. (https://twitter.com/tetsuo_cpp/status/2073409122108858378)
- [x_tetsuo_cpp#22859b24] EXTREME frontier lab employee try not to talk like a Marvel villain challenge (IMPOSSIBLE).
- [x_tetsuo_cpp#2a9764fe] This man knows his compiler developers.
- [x_tetsuo_cpp#57fd601e] To expand on this, I haven’t had to do this but I would always encourage you to take the best opportunity available to you even if it unfortunately means resigning in your first few weeks or reneging on an offer.

- commercial.audience_buyer_fit: source_type=ai_inferred, confidence=0.6, freshness_days=80, method=llm_scorer — Relative signal within Koinon indexing, not a market-wide score.

- quality.anomaly_flags: source_type=heuristic, confidence=0.5, freshness_days=110, method=profile_snapshot_and_engagement_ratio_heuristic — Means "worth a manual check", NOT confirmed fraud. Flags can be wrong and are not a verdict about the person.
- quality.authenticity_score: source_type=heuristic, confidence=0.5, freshness_days=80, method=Profile-shape heuristic from a single snapshot (follower count, following ratio, account age, posting volume, verification), reduced for engagement red flags where post engagement was collected. Where only a follower count is available the score saturates at 58. — The input set differs by platform; do not compare this score across platforms.
