From b0ebd47066fea053477a31d08d49da8285038083 Mon Sep 17 00:00:00 2001 From: Luke Curley Date: Sat, 31 Oct 2026 23:57:13 -0700 Subject: [PATCH 01/11] chore(quest): claim quest/m0/kix/land-review.md Quest-Claim: 1fd6a8759653ee72 From 15bd6ed4f910567966f931976c178599cf4f99b2 Mon Sep 17 00:00:00 2001 From: Luke Curley Date: Sun, 1 Nov 2026 00:16:48 -0700 Subject: [PATCH 02/11] feat(kix): land only heads with a review that counts on them Picking merge was the only gate between a runner-published head and main: the inbox's direct merge and a merge job's landing both went ahead on the maintainer's earlier pick, bounded only by branch rules. Both now require a review on the exact head being landed, read from GitHub's own records: an approval by a person with write access other than the author, or the App's passing `quest review` check run. A review carries across merges of the default branch that kix verifies resolved nothing, and kix defers to rulesets that enforce current-head approval and that the App cannot bypass. Otherwise a direct merge is refused and a merge job pauses on a decision, each saying which commit needs a review. The quest keeps what remains: counting a policy-named `## Review` record.

The `{ head, waiting }` landing result and the runner's handling of it go away.
