The enrichment pace on this site had been exactly one page per session since June. Every session opens with a re-verification of the previous page against the printed sources, runs the full enrichment gate on a new page, tags a song for the analysis graph, updates the homepage counters, and deploys. That overhead is fixed whether the session enriches one page or two. The question was whether a second page could ride the same session without degrading quality.
Running a controlled trial
Rather than assume, we measured. Three trial sessions paired two pages from the same recording cluster—songs cut on the same day at Abbey Road, sharing the same Lewisohn chapter, the same Kehew & Ryan equipment coverage, and the same engineer and producer. The pairing rule meant the second page could draw on source context already loaded for the first, but every citation was independently verified from scratch (a zero-carryover rule designed to catch cross-song fact bleed). Each session’s pages were re-verified at full depth next session, and we compared the patch rate against the one-page baseline.
The baseline was roughly 0.96 patches per page on re-verification. Across the three trial sessions—If I Fell paired with Tell Me Why, You Can’t Do That with I’m Happy Just to Dance with You, Long Tall Sally with I Call Your Name—the mean dropped to 0.5. Not because less was found; because more was right on the first pass. The protocol was adopted as permanent.
Draining the 1 June 1964 cluster
The first full deployment of the two-page protocol swept through the 1 June 1964 sessions at Abbey Road: Slow Down, Matchbox, Any Time at All, Things We Said Today, I’ll Cry Instead, I’ll Be Back, and When I Get Home—seven pages across four sessions. Every one of them had inherited a take count of 16 from the v1 build; every one was wrong. Slow Down was 6 takes. Matchbox was 5. Things We Said Today was 3. When I Get Home was 11. The v1 numbers had drifted in from adjacent sessions on the same day and never been checked against Lewisohn’s page headers.
Matchbox earned a note that no other page in the corpus carries: Carl Perkins was present in Studio Two that afternoon, watching Ringo record his song, although he did not play. Any Time at All had two fabricated quotes stripped—a Kozinn 1995 attribution about “harmonica whole notes” and a Lewisohn quote that appears nowhere on the cited page. These are the kinds of corrections that only surface when the source is open on the desk, not paraphrased from memory or another website.
The badge that broke the count
A quieter fix this week: two pages enriched in early July—Ask Me Why and Misery—had been written to disk with a malformed badge slug, status-review--yellow-yellow instead of status-review-yellow. The badge rendered visually but was invisible to the grep that counts enriched pages for the homepage radial chart. The enrichment counter had been two behind reality since those pages shipped. Repaired, reconciled, and the chart now reads 68 of 214.
