--- Small shared helpers: URIs, dates, notifications.

local M = {}

--- Today's date as an ISO `YYYY-MM-DD`. Uses the real wall clock — the plugin
--- picks "today"; `heph-core` stays clock-injected, this is surface-only.
function M.iso_today()

end

--- The buffer URI for a node id.
function M.node_uri(id)
  return "heph://node/" .. id
end

--- Parse a `heph://<kind>/<id>` URI into `kind, id` (nil on no match).
function M.parse_uri(uri)
  return uri:match("^heph://([^/]+)/(.+)$")
end

--- Notify with a consistent `heph:` prefix.
function M.notify(msg, level)

end
