Not sure if it'll help, here some methods to retrieve values:

\header {
  title = "My first title"
  secondtitle = "My second title"
}

\bookOutputName "my-out"

#(format #t
  "\nBindings in the header-module:\n~y"
  (ly:module->alist $defaultheader))

#(format #t
  "\ntitle from header-module, if not found fallback is used: \"~a\"\n"
  (assoc-get 'title (ly:module->alist $defaultheader)
  "fall-back-value"))

#(format #t
  "\nsecondtitle from header-module, if not found fallback is used: \"~a\"\n"
  (assoc-get 'secondtitle (ly:module->alist $defaultheader)
  "second-fall-back-value"))

#(format #t
  "\nthirdtitle from header-module, if not found fallback is used: \"~a\"\n"
  (assoc-get 'thirdtitle (ly:module->alist $defaultheader)
  "third-fall-back-value"))

#(format #t
  "\nCurrent output-filename: \"~a\"\n"
  (paper-variable (ly:parser-lookup '$current-book) 'output-filename))

#(format #t
  "\nCurrent filename: \"~a.ly\"\n"
  (ly:parser-output-name))
