single-repository.yaml: openRepoShape records that it stays a single repository, as Brett Heap decided on 2026-10-11, so the Triad advisory is no longer said here (#337)

+# OPTIONAL, AND NEVER OWED. The Triad — an assembly root with a spec leg and
+# a code leg — is the PREFERRED project shape (openxFactory
+# `prefer-triad-project-shape`, ratified by Brett Heap on 2026-10-06), and a
+# person starting work here is told so once. This file is how a project that
+# has DECIDED to stay in one repository says so, once, and stops meeting that
+# advisory. A project that writes nothing owes nothing and is reviewed
+# identically.
+#
+# IT CONFERS NOTHING. No gate, no floor, no grant, no clearance eligibility,
+# no lifecycle state and no review difference. Its only reader is
+# openRepoShape's Triad advisory; no review lane, required check, validator,
+# floor, council or merge gate reads it.
+#
+# HOW TO USE IT. Copy this file to the repository's ROOT as
+# `single-repository.yaml`, replace every value in double braces below, and
+# commit it like any other change. `revisit_on:` is optional — delete its line if
+# there is nothing to revisit. The schema is openRepoShape's
+# `contracts/single-repository-record.yaml`. Converting to the Triad later is
+# `adopt-project.py`, run by a person deciding for the project; nothing
+# converts on this file's account, and nothing reads `revisit_on:` but people.
+# ===========================================================================
+
+# The person who decided, for this project, that it stays single.
+decided_by: "Brett Heap"

+# The day they decided it, as YYYY-MM-DD.
+decided_on: "2026-10-11"

+# Why, in a sentence: a configuration repository, an aggregation, a vendored
+# fork, a project too small to split.
+reason: "openRepoShape is the standard itself: its rules (README, AGENTS.md, contracts) and the tools that apply them change together in one reviewed commit, and every project pins one commit of it."

+    checkout the advisory about the standard itself. The record is the

+    meets. The second asks for no `advisory` row rather than for no
+    `triad-advisory` row at all, because a checkout cloned under a leg's name
+    is sent to its assembly root instead and that row is not the advisory.
