Summary

Global search-and-replace across 365 files to rebrand from "hyprnote" to "char":

• Domains: hyprnote.com → char.com (URLs, emails, API endpoints, download links)
• Brand name: hyprnote → char, Hyprnote → Char, HYPRNOTE → CHAR
• Bundle IDs: com.hyprnote.* → com.char.*
• Provider/entitlement IDs: hyprnote_pro → char_pro, hyprnote_lite → char_lite, STT provider "hyprnote" → "char"
• Observability: All hyprnote.* tracing fields/tags → char.*
• Deep link schemes: hyprnote:// → char://, hyprnote-nightly:// → char-nightly://
• File renames: Flatpak files, Rust modules, AEC test data, blog MDX files, desktop assets
• Rust keyword workaround: Modules that would become mod char; (reserved keyword) were renamed to char_stt or char_app

Netlify redirect from fields correctly preserved as hyprnote.com (they redirect old domain → new domain). Blog post hyprnote-is-now-char.mdx slug preserved since it's a permalink about the rebrand.

Review & Testing Checklist for Human

• Infrastructure references: S3 bucket names (hyprnote-build, hyprnote-cache2, hyprnote.s3.us-east-1.amazonaws.com), Fly.io app names (hyprnote-ai, hyprnote-stripe, hyprnote-slack-internal), and CrabNebula slugs (fastrepl/hyprnote2) were all renamed in config. Verify these services have actually been renamed or revert these specific changes — otherwise CI/CD, deployments, and model downloads will break.
• Entitlement strings are a data contract: hyprnote_pro → char_pro in auth checks and Supabase tests. If Stripe/Supabase still stores the old lookup keys, entitlement checks will fail for all Pro users. Coordinate with Stripe entitlement config and Supabase hook.
• Bundle ID change (com.hyprnote.stable → com.char.stable): Existing macOS installations use the old bundle ID for data directories, keychain items, and code signing. Verify that the migration path is handled or that this is intentional for a clean break.
• scripts/info.sh duplicate fallback (line ~22): The old code checked /Applications/Char.app then fell back to /Applications/Hyprnote.app. Now both branches check /Applications/Char.app, making the elif dead code.
• External URLs that may not exist yet: discord.gg/char, bsky.app/profile/char.bsky.social, status.char.com, auth.char.com, storage2.char.com, desktop2.char.com, api.char.com — verify these are live or will be before merging.

Notes

• The blog post /blog/hyprnote-publishing-stack was renamed to /blog/char-publishing-stack (file rename). No redirect was added for the old URL — consider adding one to netlify.toml if this post has external backlinks.
• All Honeycomb/Sentry dashboards using hyprnote.* field names will need updating after this lands.
• Developer local credential files referenced in scripts (~/hyprnote-r2.toml, ~/hyprnote-s3.toml) were renamed — team members will need to rename their local files.
