**Verification notes — 25 October 2026**

The guide is a research and planning artifact. No product code, pricing, billing, analytics, publication or external account settings were changed.

- User confirmed existing web, Android and iOS apps and existing daily predictions, birth-chart readings, reports and auspicious ceremony timings. The roadmap treats these as existing assets.
- Internal engine implementation, licences, traffic, payments, unit costs and founder capacity were not available for audit. The guide identifies these as unknowns; the 50-hour weekly allocation is a planning assumption.
- Public product observations were rechecked against Astro Chanakya's homepage, horoscope, Kuja and privacy pages. Public text can lag deployments, so the guide asks the founders to reconcile labels with the actual implementation.
- Competitor feature and price observations are taken from primary public pages. No competitor purchase or private retention analysis was performed. AstroSage usage is labelled a company claim.
- Subscription findings are attributed to RevenueCat and retain their observational and population limitations. The guide does not treat them as causal estimates or astrology-specific benchmarks.
- The existing social-audit statistics were read from the saved statistics file. Sample sizes and limitations accompany the limited comparisons reused in the guide.
- All proposed sample sizes, thresholds, prices, sequencing and unit-economic assumptions are explicitly proposed rather than observed results.
- Checked 35 unique backlog IDs and all dependency references. Every item remains Proposed or Conditional.
- Checked every linked local artifact exists.
- Checked 2 November 2026 through 30 January 2027 is 90 days inclusive. Subscription renewal examples explicitly acknowledge observation beyond the window.
- Recomputed illustrative contribution: ₹142, ₹92 and −₹33; margins 71%, 46% and −16.5%. ₹150,000 / ₹122 rounds up to 1,230 payers. Free-answer allocation examples are ₹20 and ₹100 under the stated consumption and conversion assumptions.
- The computational-quality, interpretation-fidelity and user-usefulness measures are separated from unestablished predictive validity.

Primary sources are linked next to the claims they support in the guide. The remaining roadmap and architecture are recommendations tailored to the stated product, not completed implementations or externally validated business forecasts.
