Thanks for the PR! Given that this is the first classmaps external contribution, what was your experience generating these @Mralimoh?

[afonsojramos]

Resolved the index conflict while preserving both 1020098 and 1020099. Regenerated checksums now match all 24 staged Git blobs; index and exposure validation and all 18 regression tests pass. Accepting the contributor-reported Spotify 1.2.99 live verification.

Thanks @afonsojramos! It's great to be the first external contributor.

Honestly, the experience was great. I automated the reverse-engineering workflow by guiding an AI agent through CDP on port 9222. It took dozens of runtime probes to trace the live DOM changes (like the new encore e-10810 prefix and readable module classes), but the repo's structure and validation scripts (build_index.py --check) made verifying the generated data very straightforward.

Looking forward to running this pipeline for upcoming Spotify releases!😂

@Mralimoh yeah, I usually get my updates a couple days later, so I'll appreciate the help!
