The wikitext contains 5 templates, but only the previous three of them have data-mw counterparts in rdf.

Note that a single data-mw can contain multiple templates in its parts. Generally, this happens when multiple templates are used to form a single element. Here's the data-mw containing the missing templates,

data-mw='{"parts":["{|",{"template":{"target":{"wt":"Infobox ship begin","href":"./Template:Infobox_ship_begin"},"params":{},"i":0}},"\n",{"template":{"target":{"wt":"Infobox ship career\n","href":"./Template:Infobox_ship_career"},"params":{"Hide header":{"wt":""},"Ship country":{"wt":"United States"},"Ship flag":{"wt":"{{shipboxflag|United States|coast guard}}"},"Ship name":{"wt":"USCGC &#39;&#39;Point Evans&#39;&#39; (WPB-82354)"},"Ship owner":{"wt":"United States Coast Guard"},"Ship namesake":{"wt":"Point Evans at [[Gig Harbor, Washington]]"},"Ship ordered":{"wt":""},"Ship builder":{"wt":"J.M.

Unfortunately, Infobox ship image, the second Infobox ship career, and the second Infobox ship characteristics are being appended as source strings, instead of objects with template keys. Rendering does seem to be correct, and those templates are at least tokenized correctly.

Thanks for the explanation. The problem is we can't get the tokenization results for the last three templates from data-mw, because they're plain strings. Use "Infobox ship image" as an example, from data-mw we can only get

`"{{Infobox ship image\n| Ship image               =&lt;!-- Deleted image removed: [[File:BRP Alberto Navarette.jpg|300px|]] -->\n| Ship caption             =As BRP &#39;&#39;Alberto Navarette&#39;&#39; (PG-394)\n}}"`

Can we get structured results like

{"template":{"target":{"wt":"Infobox ship image", "params":{"Ship caption":{"wt":"As BRP ''Alberto Navarette'' (PG-394)"}

without parsing the wikitext template ourselves?

@Renxiaoyi That's why I left this open. It is indeed a bug. It shouldn't be a string.

Arlolra set Security to None.

The patch fixes the bug but I also edited the article to close the template, which fixes the page before the patch is deployed.
