v0.5.1

• A decision the page redraws under is dropped at once. While Jev decides and gates a click, the run watches
  the controls on offer; if one changes, as Google Flights' date picker does when its prices arrive late, it
  decides again on the settled page instead of clicking into a stale refusal.
• A guessed shortcut the site does not serve is skipped. A direct address that answers 4xx/5xx sends the
  run back to its start page instead of reading an error page and spending a BACK to leave it.
• Runs use a Browser Use Cloud browser by default (BROWSER_USE_API_KEY). --local runs local Chrome;
  --headed, --profile, FASTBROWSE_HEADED and FASTBROWSE_PROFILE imply it. --cloud is removed.
  --cloud-profile with local Chrome is refused at startup.
• A failure says what happened. Each retry logs the call, the provider's status and error, and the
  backoff; a call that gives up names how many requests failed, over how long, and the last cause. Evals
  lead every failed run with how it ended, and print which providers (and whether a backup) they use.
• unavailable is its own status. A run that ends because a model or browser provider stayed unavailable
  through every retry reports unavailable rather than error: nothing about the task failed. The live evals
  run such a run again, so a published result is the agent's own.
• An error never quotes a key. Error text built from a provider's response omits the values validation
  rejected and scrubs the key wherever it appears, including a model's own JSON keys.
• A browser that stops answering is an outage; a slow one is not. A CDP command with no reply after 60s asks
  the browser whether it is still there, and keeps waiting if it answers. Only a browser that does not ends the
  run unavailable, where before a lost cloud browser could leave it waiting forever.
• Eval arms are named for their agent: --arms fastbrowse jev-ultrafast browser-use.
• Recordings are captioned and kept plain beside them (<name>.plain.mp4). Captions are timed from the
  video's first frame; an ffmpeg without libass still writes both videos, uncaptioned, and a failed write
  leaves an earlier recording at the same path intact.
• Clicks are safer on covered controls. A covered control is clicked at an exposed edge only when no
  other control (a row's own Delete button) sits under that point; a hover-only region inside a button does not
  count as one. A select the page reverts is a failed step.
• A recording ends on a readable answer. The closing card shows each citation as a number beside the
  claim and lists the cited site and quote underneath, instead of the raw text-fragment link.
• A run reports where its recording went. RunResult.recordings lists the videos written; the CLI prints
  recorded: <paths> or not recorded, and prints warnings to stderr.
• Local Chrome has no password popups. Every launch switches off Chrome's password manager and leak
  detection, in a kept --profile too; a kept profile whose preferences cannot be read is a BrowserError.
• Finishing is judged more carefully. A lookup that has its answer ends rather than clicking on; a search
  the task only asks to run is a requirement to act on; the verifier confirms requirements one by one, sees the
  controls that are set and the ones the done check doubted, and a narrowing requirement needs its filter
  applied rather than matching rows.
• Pages are read when they have settled. Navigation waits for the loaded page's DOM to go quiet; a
  transparent checkbox styled by its ancestors is offered; an aria-disabled="false" added during hydration is
  not a new control.
