+# [S] Record each project's service fork by repository ID
+
+## Goal
+
+Two enrolled upstreams with the same repository name, such as `alice/app` and
+`bob/app`, each publish through their own service fork. Publication finds a
+project's fork by its stored GitHub repository ID, not by
+`GITHUB_FORK_OWNER/<upstream name>`, so names can never collide or be
+mistaken for one another.
+
+## Plan
+
+Decided 2026-10-19 as a follow-up of bot publication (#145), which looks the
+fork up by the upstream's name:
+
+- The operator keeps creating each fork by hand in the `GITHUB_FORK_OWNER`
+  namespace, under any name (for example `bob-app`). The App gains no
+  repository-creation permission.
+- kix records the fork's repository ID per project when it first finds it,
+  after verifying that the fork's parent is that project's upstream. Later
+  publications use the ID and refuse a fork whose identity or parent has
+  changed.
+- How kix first finds a fork under a non-default name (an operator-entered
+  name at enrollment, or a scan of the namespace for a fork whose parent is
+  the upstream) is an implementation choice; prefer the one with fewer
+  GitHub calls and no new permissions.
+- A project with no recorded or discoverable fork keeps today's "provision
+  the service fork first" refusal, naming what the operator must create.
+- Disconnecting a project clears its recorded fork. Update the fork steps in
+  `cloudflare/GITHUB.md`.
+- Land this in m0 before launch: kix.quest is public in m0, so any enrolled
+  repository could collide.
+- Test two same-named upstreams, a fork with a changed parent, and a missing
+  fork.
+
+## Required

+# [S] Render planning decisions into PRs from recorded answers
+
+## Goal
+
+A planning PR published by kix carries a decision section that the service
+writes from the job's recorded questions and answers, with ✅ on each chosen
+option and any free-text answer. The agent no longer writes its own paper
+trail, so the record cannot be paraphrased or drift from what the maintainer
+actually chose.
+
+## Plan
+
+Decided 2026-10-19 as a follow-up of bot publication (#145), which takes the
+paper trail from the agent's quest files and PR body:
+
+- The service renders the section from the job's stored questions and
+  answers (the decision inbox's prompt contract) when it creates or updates
+  the planning PR. Include only answered `agent` questions whose prompt is a
+  `decision`, not a `permission` request. Operational question kinds such as
+  `account` and `publication` stay out, since they can name runners and
+  accounts in a public PR.
+- Prompts and answers are untrusted text. Escaping Markdown is not enough:
+  also neutralize GitHub's own semantics, so no `@` mention notifies anyone,
+  no `#N`, `owner/repo#N`, or commit reference autolinks, no bare URL links,
+  and no closing keyword (`Closes #N`, `Fixes`, `Resolves`) links or closes
+  an issue. For example, render all prompt text in code spans or break each
+  pattern with a zero-width character.
+- Replace, don't append: the agent's PR body keeps its summary, and the
+  service owns the decision section. Re-rendering on later deliveries
+  updates the same section in place rather than duplicating it.
+- Quest files still record each settled decision and its reason in their
+  Plan, as the guide requires; this changes only the PR's paper trail.
+- Tell agents in kix planning jobs, through the job's own instructions
+  rather than the shared skills, not to write the trail. Local agents running
+  the skills without kix keep writing their own.
+- Test multi-round interviews, free-text answers, a re-delivery that
+  updates the section, and a planning job that hit an account limit, whose
+  account question must not appear. Cover hostile prompts with Markdown,
+  `@user` and `@org/team` mentions, bare URLs, issue and cross-repository
+  references, and closing keywords.
