fix(web): follow a POST redirect that lands on a different page - #581
Conversation
Closing the workspace's LAST tab left a stale "Close?" pill on screen (issue #579): the /sessions/delete route 303s back to the workspace, but the workspace's own do_GET 303s again to the settings page once zero sessions remain. fetch() follows both redirects transparently, so the submit handler's post() patched fragments out of the SETTINGS page's HTML — which has no #tab-bar id at all, so applyDoc silently skipped it and the old tab-bar (armed button included) sat untouched. fetchPage() already guards against exactly this ("the daemon can decide the current URL is no longer the right page") for the periodic poll path; post() now does the same real navigation instead of patching an unrelated page's fragments into the live DOM.

16752-16768: 📐 Maintainability & Code Quality | 🔵 Trivial | ⚡ Quick winExtract the shared redirect-settlement logic.
post()duplicatesfetchPage()'s redirect handling exactly: capturehere, checkr.redirectedand the pathname, then either callwindow.location.replace(r.url)and resolvenull, or resolver.text(). Keep this logic in one place. Two copies can drift apart the next time the redirect rule changes, and only one copy would get the fix.♻️ Proposed refactor

post() duplicated fetchPage()'s redirect handling exactly. Pull it into settleRedirect() so future changes to that rule apply to both callers at once. Addresses a CodeRabbit nitpick on PR #581.

CI green, CodeRabbit's nitpick (extracting the shared redirect-settlement logic) addressed in the follow-up commit, no other review threads open. I won't merge this myself — say the word and I will, or feel free to merge it yourself. |

That test suite isn't run in CI (E2E_BASE_URL-gated, run manually against a live box), so I didn't want to add a test that's destructive to whichever box someone points it at.Test plan
