MetalBear gains account-cache eviction, durable blob storage, multipart video uploads, and a modular build profile
Account contexts are now bounded with configurable resident budgets and count-based eviction. Blob payloads persist to disk instead of memory. Video uploads support durable multipart with reservations and lexicon-aligned limits. The frontend shows multipart capability. AppView proxies getUnreadCount. Per-route metrics replaced per-handler ones. A modular build profile (uncommitted) compiles out optional modules for constrained targets.

Use Precomputed Hashes Instead of BCrypt in Test
I asked Claude to find the slowest test file again after my success [earlier today](/speeding-up-willow-camp-s-post_test-rb-by-99) and Claude found a call to BCrypt in my fixtures that was gobbling up time.

Benchmarking Cloudflare R2 HEAD Requests from Cloudflare Workers
Why would I do this? For my latest project, mapvoyage, I need to serve text files (wikitext to be specific), directly to the user if possible, as well as in a separate function select one wikitext file to display from a list of wikidata ids that may or may not have an associated wikitext file. Latency is important and I'd like the data to be edge-available if possible. R2 with workers seemed ideal here, as the client can download the files from R2 directly and I can lookup the urls from a separate worker, which hopefully shouldn't have a long latency for reading them.
