+# ASW Caddy Directory Listing — Caddyfile snippet
+#
+# Caddy's `file_server browse` outputs its own HTML, but accepts a custom
+# template file via `browse { template_file }`. The template is a Go HTML
+# template with access to directory metadata and file entries.
+#
+# See: browse.html in this directory for the ASW-styled template.
+
+# ── Option A: Custom template (recommended, Caddy v2.6+) ─────────────────────
+#
+# Full control over the listing HTML. Browse template receives:
+#   .Name     — directory name (last path segment)
+#   .Path     — current URL path (e.g. "/files/")
+#   .Files    — []FileInfo, each with:
+#                 .Name, .Size, .URL, .ModTime, .IsDir, .IsSymlink
+
+handle /files/* {
+    root * /var/www/files
+    file_server browse {
+        index off
+        browse {
+            template_file /home/exedev/projects/agentic-semantic-web/packs/caddy/browse.html
+        }
+    }
+}
+
+
+# ── Option B: Default Caddy browse (quick, no custom template) ────────────────
+#
+# Uses Caddy's built-in file browser. Functional but unstyled.
+# Upgrade to Option A when you want ASW aesthetics.
+#
+# handle /files/* {
+#     root * /var/www/files
+#     file_server browse
+# }
+
+
+# ── Example: expose the ASW repo itself for browsing ─────────────────────────
+#
+# example.com {
+#     handle /asw/browse/* {
+#         uri strip_prefix /asw/browse
+#         root * /home/exedev/projects/agentic-semantic-web
+#         file_server browse {
+#             browse {
+#                 template_file /home/exedev/projects/agentic-semantic-web/packs/caddy/browse.html
+#             }
+#         }
+#     }
+# }
