+# [XS] Move to the next decision after an answer
+
+## Goal
+
+After a maintainer answers a decision in the inbox, the page moves on to the
+next active decision with a short "Answer recorded" notice. When an action is
+refused, the page has a neutral title and says why, whatever the action was.
+
+## Plan
+
+Decided 2026-10-19 as a follow-up of the decision inbox (#144), which stays
+on the item just answered, and titles every refusal "Not recorded" even for
+a refused "Refresh from GitHub":
+
+- Redirect to the next active decision, or to the inbox's empty state, and
+  show the notice there. The answered item stays reachable under its
+  earlier answers.
+- Retitle the refused-action page neutrally (for example "Couldn't do
+  that"), with the specific reason and a link back to the item.
+- Keep the form posts working without JavaScript. Update the inbox tests.
+
+## Required
+
+- [Decision inbox](/quest/m0/kix/prompts.md) - the answer and refusal pages this changes

+# [M] Run the Worker locally with seeded data
+
+## Goal
+
+One checked-in command, such as `just dev-seeded`, serves the real Worker
+locally with representative seeded data, mocked GitHub, and a local sign-in,
+so agents and maintainers can check UI changes in a browser at phone and
+desktop widths. It works inside sandboxed agent environments, where
+`wrangler dev` currently hangs.
+
+## Plan
+
+Decided 2026-10-19 as a follow-up of the decision inbox (#144). Its
+browser check needed a throwaway harness because `wrangler dev`'s internal
+proxy hangs in the agent sandbox on a DNS lookup of "dummy":
+
+- Check in a seeded harness rather than debugging `wrangler dev` for one
+  agent environment. Bundle the Worker as `wrangler deploy --dry-run` does,
+  serve it with Miniflare on local D1 and R2, and apply the checked-in
+  migrations.
+- Mock GitHub's REST API and short-circuit the OAuth redirect so sign-in
+  completes locally. The mock serves only localhost and never holds real
+  credentials; it is development tooling, not a production code path.
+- Seed representative state: agent prompts with several questions, an
+  account limit, failed, queued and running jobs, PRs with checks and
+  reviews, issues including a pointer-only one and a long title, ready
+  quests, and a paused project.
+- Keep the seed and mock reusable as the base for the kix epic's stubbed
+  end-to-end test, rather than a second fixture set. Share fixtures with
+  the Worker tests where practical.
+- Document the command in `cloudflare/README.md` as the way to check UI
+  changes in a browser.
