+## GSC-backed snippet and conversion repair (2026-10-27)
+
+A **restricted 3-day finalized GSC window (Oct 22–24)** was available, so do not treat the following as significant performance trends: BrainBurst support 14 impressions / 0 clicks / average position ~9.1; SnapLingo support 10 impressions / 0 clicks / position ~7.4; `face battle` query on Face Reaction Battle page 13 impressions / 1 click / position ~5.9. No prior-period comparison available.
+
+- BrainBurst: correct the stale generic memory/math training synopsis to the Play-aligned daily AI trivia / 1v1 quiz proposition, improve search/snippet and open-graph fields; show Google Play CTA above the fold.
+- SnapLingo: concrete photo vocabulary search snippet and high-visibility store handoff, with app structured data but **no manufactured review stars/rating scores**.
+- Face Reaction Battle is **not downloadable**, so retain unavailability notice. Offer only clearly **different**, verifiably published Instant Judge and Blur games; do not imply they provide face-expression recognition.
+- `robots.txt` now explicitly allows public `/icons/apps/` while continuing to disallow remaining icons. Note indexing is a search engine decision, not guaranteed.
+- Preserve Google Play Install Referrer on each CTA. `download_click` adds `app` and `placement` so support hero CTA and page-details CTA can be compared; avoid raw visitor search content.
+- New `tests/search-landing-growth.test.mjs` and GitHub CI prevent catalog/product mismatches, fabricated ratings, missing store links, and missing live-check assertions.
+
+After shipping the updated **nine** files from a fresh main checkout, run `bash scripts/check_app_discovery_live.sh`. Record the deploy timestamp, then compare **landing impressions/CTR**, **support CTA clicks by placement**, **Play visitors/install**, and **first completed app action** after enough data accumulates. The early data is directional only.
