 # Changelog
 
+## Unreleased — August 22 recording-sequence ingestion
+
+- Added two creator-verified Standard recordings dated August 22, 2026,
+  totaling 32,990,632,238 bytes and 2,518.638998 seconds of encoded playback.
+- Increased active membership to 362 Standard plus 128 Pre-Standard records
+  without changing the 29-field schema or `standard-2025-07-13` protocol ID.
+- Retained literal `Rec01` and `Rec02` filename suffixes for the continuing
+  14 × 17 in sequence. `Rec03` is expected, and no sequence endpoint is claimed.
+- Verified direct visual continuity and drawing progression from `Rec01` into
+  `Rec02`; integrity validation covers the complete video and audio streams.

 ## Unreleased — August 2026 Standard ingestion
