+- Added three creator-verified Standard recordings dated August 17–19, 2026,
+  totaling 50,478,909,746 bytes and 3,856.391997 seconds of encoded playback.
+- Increased active membership to 360 Standard plus 128 Pre-Standard records
+  without changing the 29-field schema or `standard-2025-07-13` protocol ID.
+- Fully decoded all 231,383 video frames and every audio stream; no source
+  corruption, dropped frames, duplicated frames, or broken endpoints were
+  found.
+- Added the first 14 × 17 in Standard record and documented its Strathmore 500
+  Series Premium Bristol plate surface from the creator-supplied packaging.
+- Retained `Rec01` on the 14 × 17 in filename because `Rec02` is expected; the
+  suffix distinguishes recording sequence only.
+- Applied media integrity, identity, rights, and traceable-metadata criteria
+  without filtering by perceived artistic quality.
