Reject external script references.
The current assertion rejects only ./main.js. An external script with another src value can pass this check. If it also carries the expected nonce, it can satisfy the remaining assertion while recreating the Linux CSP failure. Assert that no <script> element has a src attribute.

‼️ IMPORTANT
Carefully review the code before committing. Ensure that it accurately replaces the highlighted code, contains no missing lines, and has no issues with indentation. Thoroughly test & benchmark the code to ensure it meets the requirements.

Summary
On Linux the desktop bootstrap window ran none of its JavaScript. The page rendered, the phase
checklist stayed empty, the headline stayed on the markup default, and no terminal state was ever
reached — so the one surface whose job is to report a failed start could not report anything.
Closes #5416.
The cause is not the asset and not the MIME type. The webview is not served the policy in
tauri.conf.json: the shell appends its own hashes and nonces toscript-srcbefore serving thepage. Once a hash or a nonce appears in that directive, any inline allowance is inert, so every
script has to be named individually. The shell's own nonce injector matches
script[src^='http']only, and this page loaded its script by relative path, so it was never named. Where the asset
origin does not satisfy
'self'— Linux, measured — the script is refused and the page is astatic picture.
The page and its script now ship as one file. An inline script carrying the nonce token is named
by the same mechanism that names the shell's own scripts, so the surface runs with the policy
intact rather than by weakening it.
desktop/ui/main.jsis gone; its contents are unchangedinside
index.html, and the comment above it records why the file may not come back.Verification
is static review plus hosted CI at the exact head.
branch each time:
status=200,content-type: text/javascript, 5941 bytes;first placed the cause in the policy rather than the asset;
script-srcchanged nothing, and adding'unsafe-inline'changed nothing either — the signal that a hash or nonce was already presentand making inline allowances inert;
same token still did not, which is what makes inlining the fix rather than a workaround;
script[src^='http'], and the nonce replacement scans the asset for the token, substitutes afresh value, and adds
'nonce-…'plus'self'to the directive.tests/clients/desktop-startup-surface.test.tsnow reads the single pageand asserts both that no second script file is referenced and that the inline script carries the
token. It fails against the previous revision, where the reference existed and the token did not.
A separate observation, not fixed here: with the surface alive, the checklist renders but stays
pending — the shell publishes no progress snapshot on this platform. That is a shell-side gap and
it is now visible precisely because the page runs.
