Three faults, one subsystem, and the middle one is why a request that looked obviously satisfiable came back refused. **The guardrails were in megabytes, which cannot mean anything.** 300 MB is a generous FLAC single and a suspiciously small boxset, and whoever fills the field in has no idea which release the pipeline will apply it to. `MinKbps`/`MaxKbps`/`PreferredKbps` are the same statement divided by how long the music is, so one number holds across a nine-minute EP and a three-hour opera. The runtime comes from `Download.Expected`, which every anchored request already carries, so this costs no lookup; the rate is audio bytes over that, falling back to the mean stated per-file bitrate when the runtime is unknown. Artwork is excluded from the numerator, or a folder with 30 MB of scans reads as a better rip. An unknown runtime *passes* the window rather than failing it: the window is a statement about quality, and refusing everything the moment MusicBrainz is missing a track length would be a silent embargo. `MaxFileSizeMB` survives as a separate ceiling, still in megabytes on purpose -- it is a question about disk space, and it has to apply to a candidate whose bitrate cannot be worked out at all. **Auto-pick required daylight over the runner-up**, 0.08 on the combined score, and so fired hardest in the case it was never written for: a popular album turns up five *correct* copies, all matching the tracklist at 95%+ and differing only in format and seeders, their scores land within a point of each other, and it refused forever on the grounds that the choice was the user's. It was not. There was no question about what to fetch, only about which copy -- and abundance is the condition under which that matters least. A candidate no longer has to beat the field, only clear the bars on its own terms; where several do, ranking puts the one closest to the preferred bitrate first. That tie-break needed the preference to carry weight or it would have been decorative in a new unit: `BitrateFit` was 0.05 against format's 0.42, so asking for 320 and being handed a FLAC every time was the designed behaviour. When a preference is set the weights shift to fit 0.40 / format 0.20 / bitrate 0.10, taking it off the two heuristics that exist as stand-ins for the preference the user has now given. Health and priority are untouched. And the fit spans 0.5 to 1.0 rather than 0 to 1, so a preference can promote the copy that matches it and can never push the others under `minQuality` -- turning "I like 320" into "never take anything else" silently is what `MinKbps`/`MaxKbps` are for, out loud. **And a refusal quoted numbers that passed.** The request list built its message from `ranked[0]` -- the best candidate *before* the guardrails and before the lead check -- so a request killed by the size window, or by having too many good copies, reported "best of 12 found is not a confident enough match (match 96%, quality 88%)". `AutoPickVeto` names the gate that actually refused, and `AutoPickable` is that returning empty. Existing configs: the old `MinFileSizeMB`/`PreferredFileSizeMB` are not migrated. A number meaning "300 MB" cannot be reinterpreted as a rate without knowing the album it was aimed at, so carrying it over would be inventing an intent nobody expressed. Those two fall back to no window, which is the permissive default and what a fresh install gets; `MaxFileSizeMB` carries over unchanged, because a ceiling on bytes still means exactly what it did.

YellowJacket Frontend
This directory contains the frontend for YellowJacket.
Dependencies
There are a couple of tools that are required to build and use the frontend.
vitefor- transpiling typescript
- bundling the final "package" that is useb by the webview
- running a dev server with hot-reloading
- configured with the
vite.config.tsfile in this directory
pnpmfor managing frontend dependency packages
There are a handful of dependency packages that we use directly in the frontend.
picocssfor basic CSS while developinglitfor a simple but powerful wrapper around Web Components
Lastly, there are some dependencies that only benefit development
tsservercomes bundled with vscode and can be used as an LSP with other editors usingtypescript-language-server- Used for autocomplete, syntax highlighting, etc.
- This can be configured with the
tsconfig.jsonfile in the root of the project- NOTE: your configuration should align with the
viteconfig so you get in-editor feedback that aligns with how the build will be done.
- NOTE: your configuration should align with the
Development
Ideally, you would use the frontend in the wails app as the frontend depends on the Go bindings generated by Wails.
You can do this by running wails dev in the root of the YellowJacket repo.
If you want to run the frontend standalone, make sure the Wails go bindings have been generated with wails generate modules.
Then, you can run pnpm dev to run the vite dev server.
For more information on what commands are available, refer to package.json.
Code
Web Components
Our frontend is based off of Web Components, a standard that provides native browser encapsulation of components that can include HTML, CSS and Javascript all together.
Instead of writing these components manually in Javascript, we utilize lit as a wrapper library.
Typescript
To better integrate with our tooling and to provide a better developer experience with strong typing, we have written all functional frontend code in Typescript. Vite serves as our Typescript transpiler.
Important Files and Directories
NOTE: most of these directories have aliases defined in tsconfig.json and vite.config.ts so that we may refer to them by shorthand when importing.
