Response: a plain-text envelope (window, freshness, column contract, this page's caveats) followed by the data table (csv, or format: "markdown") at day grain.

Response columns

name	type	description
utc_day	date	UTC calendar day (bucketed at UTC, not session TZ)
new_native_app_count	integer	Distinct native apps whose first release was that day

What is counted

'Native' means every app EXCEPT those published by the Zapstore curator key that are not Zapstore's own first-party apps (the curator's other entries are GitHub/F-Droid republishes); it is the exact complement of the partition behind zapstore.new_republished_app_count (and zapstore.republished_release_count), so the two apps series sum to all apps ever released.

Caveats

First appearance is MIN(created_at) over ALL kind-30063 history, deliberately NOT the kind-32267 (zapstore-app-catalog) catalog: 32267 is replaceable and only the latest revision survives, so its MIN(created_at) returns the latest REPUBLICATION date (measured mean lag 57.7 days; 44% of apps would appear >30 days late).
This series counts APPS; for every release event in the same partition (each version, not just the first) use zapstore.native_release_count, which bounds this one from above.
Series is sparse: days with zero new native apps are omitted.

Freshness in every response is data-derived: latest kind-30063 (zapstore-app-releases) event time.
