From eb1607aaf84c28d15205dd2e6b118c92bbc3d09d Mon Sep 17 00:00:00 2001 From: Garry Tan Date: Tue, 25 Aug 2026 15:37:00 +0000 Subject: [PATCH] test: skill-start contract suite + preamble A/B eval + touchfiles registration MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit test/gstack-skill-start.test.ts (11 free tests): STATUS-key contract vs the prose (F2), per-host fence resolution shapes (E1), proto-first, OV4 marker sanitization, --parent-pid identity, headless suppression, skill-end duration math + pending cleanup. test/skill-e2e-preamble-script-ab.test.ts (gate tier, OV7): inline-bash render (pinned from 29785978) vs script render with the fence redirected at the worktree bin (EOV2 — hermetic evals otherwise resolve the operator install and silently exercise degraded mode). 21 touchfiles dep lists gain the two bin scripts (EOV9) so future script edits select the preamble evals; selection-count pin updated 23->24.
