Find a name, then inspect matching content

The entries below contain every line in the tiny supplied tree.
*.txt is a filename pattern. Quoting it passes it unchanged to find;
leaving notes/*.txt unquoted lets the shell select these named files.
grep -n numbers lines from one in each source file.

Files contain exactly the shown lines.
search-tree/notes/alpha.txt:
  task=inventory
  status=WAIT
search-tree/notes/beta.txt:
  task=practice
  status=READY
search-tree/notes/readme.log:
  status=ARCHIVED
Owned activity: find . -type f -name '*.txt'
Then inspect cat notes/beta.txt and grep -n 'status' notes/beta.txt.
Predicted status line in beta.txt: 2:status=READY
Search all .txt files with grep -n 'status' notes/*.txt; order may vary.
Question task: search known text READY inside a file, not change its mode.
