## Engagement
- status: peak_post_only
- peak_post_engagement_rate: 0.00019
- best_post_interactions: 8
- 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_caleb_friesen#b34998c6] This IIT Madras-incubated startup (@Neuro_stellar) was prototyping EEG BCI beanies years before neurotech blew up, and before Vinod Khosla backed Sabi. Neurostellar has since zeroed in on a headband form factor (they're not working on beanies anymore). Cool bit of lore though. ht (https://twitter.com/caleb_friesen/status/1658370263569027073)
- [x_caleb_friesen#b31b85cb] The ADX-1 from Hyderabad-based Apollyon Dynamics is airborne! This is an astonishing accomplishment from such a young team. They've experienced a few crashes in the lead up to this moment too, building on those learnings to get Nightshade into the air for a controlled flight. htt
- [x_caleb_friesen#7e297d03] Visiting Canada for a few weeks. Was not expecting to see this at Walmart! https://t.co/IvemePSMtd
- [x_caleb_friesen#67a25725] As a licensed pleasure craft operator (weird lore drop lol), I find this very cool. There's nothing like driving fast boats/jetskis. Even cooler is the fact that they're based in a tier 2 ci

- commercial.audience_buyer_fit: source_type=ai_inferred, confidence=0.6, freshness_days=77, method=llm_scorer — Relative signal within Koinon indexing, not a market-wide score.
- commercial.promotion_intent: source_type=ai_inferred, confidence=0.6, freshness_days=77, method=llm_scorer
- quality.anomaly_flags: source_type=heuristic, confidence=0.5, freshness_days=108, 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=77, 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.
- quality.koinon_bd_grade: source_type=ai_inferred, confidence=0.5, freshness_days=108, method=llm_partner_fit_classifier + fit_score >= 0.6 AND authenticity >= 60 => A; fit_score >= 0.4 AND authenticity >= 45 => B; else C. authenticity < 30 or a promotional-pattern flag => quarantine. — Koinon partner-outreach fit, not creator quality.
