+# nsheaps org-wide repository defaults — TEMPLATE
+#
+# This file is the source of truth. It contains ${ENV_VAR} placeholders
+# that get substituted by the sync-org-settings workflow (envsubst),
+# which writes two rendered outputs back to this repo:
+#   - .github/org-settings.yaml      — rendered (no @default hydration)
+#   - .github/default-settings.yaml  — rendered + @default uncommented
+# Edit THIS file for org-wide changes; the rendered outputs are auto-generated.
+#
+# Sync workflow:
+#   https://github.com/nsheaps/.github/blob/main/.github/workflows/sync-org-settings.yaml
+#
+# After rendering, the ansible playbook (sync-org-settings) walks every
+# managed repo and either:
+#   - First-touch (no .github/settings.yml in target) → pushes default-settings.yaml
+#   - Existing target                                 → merges org-settings.yaml in
+#
+# Merger script + tests:
+#   https://github.com/nsheaps/.github/blob/main/scripts/org_settings_merge.py
+#
+# Merge semantics — short version:
+#   - scalars             : target wins (repo's existing value preserved)
+#   - mappings            : recurse
+#   - rulesets[]          : matched by `name`, deep-merged per item
+#   - rulesets[].rules[]  : matched by `type`, deep-merged per item
+#   - bypass_actors[]     : matched by (actor_id, actor_type) — SOURCE wins on scalars
+#   - enforcement omitted : normalized to `active` at write time
+#
+# Do not set per-repo identity (name/description/homepage/topics) here —
+# those belong to each repo.
+#
+# `# @default` convention: lines tagged `# @default` are uncommented ONLY
+# on a repo's FIRST sync (when it has no settings.yml yet). After that the
+# commented source line is invisible to deep-merge, so a later change to
+# the commented value can't accidentally overwrite the repo's value.

+#   - evaluate  : rules are checked and reported but not enforced (preview)
+# NOTE: If `enforcement` is omitted on a ruleset, the sync writer fills it
+# with `active`. Each ruleset below either:
+#   - sets `enforcement: active` (always-on org policy — overriding is discouraged), or
+#   - sets `enforcement: disabled` plus a commented `# enforcement: 'active'`
+#     sibling that a repo can uncomment (and delete the disabled line) to enable, or

+#     hint that a repo can uncomment to lock the ruleset on explicitly.

+# bypass_actors[].bypass_mode values:

+# NOTE: omitting bypass_mode lets the merger fill `always`.
+#
+# Every ruleset seeds repo admins (RepositoryRole id 5) as bypass actors so
+# the org doesn't lock admins out. Repos can append more bypass_actors; for
+# the admin entry itself, source-wins (you can't silently widen admin bypass
+# to `always` if the org set `pull_request`).
