What's updated

Three AutoEQ profiles received refreshed filter values from upstream measurements:

• Beats Studio Buds (Measured by Rtings) — preamp -2.7 dB → -3.8 dB, band structure significantly revised including a +10.6 dB low shelf
• Cambridge Audio Melomania 1 (Measured by Rtings) — preamp -6.9 dB → -6.4 dB, midrange band tweaks
• Unique Melody Mason V3 (Measured by crinacle) — preamp -4.5 dB → -5.3 dB, bass shelf significantly revised

Note on AutoEQ "385 updated"

The AutoEQ summary reports 385 updated EQs, but only 3 files appear in the diff. This is the same pre-existing counter quirk noted in previous imports — the importer counts writes but those writes produce identical content after normalization for the vast majority of entries. The real on-disk impact is 3 AutoEQ profile updates.

Quality checks

• All 3 modified files have valid JSON and trailing newlines
• 0 download errors on either source (1,068 oratory PDFs processed cleanly)
• 0 global cooldowns triggered — Dropbox cooperated throughout the run
• No new duplicates from upstream — the corrections system (Add import corrections system for upstream data quality issues #80) continues to prevent the known problematic slugs from being created
