" summary

Starts with an actionable claim: you can debug anything by getting a third‑party view of runtime behavior, strace attach to a running Apache process reveals system calls, working work backwards from the client 500 shows a missing db.in.php typo and a site restored in 3 minutes. For package tooling a megabyte of strace output plus apt source inspection finds a strict HTTP parser rejecting an empty Content‑Type header flagged as bad header line fixed by setting Content‑Type on S3.
