How Should You Treat Old Error PDFs as Historical, Not Live?

A diagnostic export proves what happened in its capture window. It does not prove the same bug is active after fixes and deployments.

Saved error reports are valuable because they preserve counts and context from a past session. Their apparent authority can become a problem when a later review cites them as current production status without a new reproduction.

The July 24 diagnostic PDF was reported fixed by August 1. It remains useful history, but current claims need fresh logs, a new session export, or a direct reproduction against the active Version 14 site.

What was actually going wrong

A real historical error was treated as timeless evidence of a live defect.

What I tried

What finally worked

Reports are labeled by capture date and status, then compared with fresh diagnostics before reopening an issue.

Why it worked

Historical evidence remains available without overriding newer runtime evidence.

What I learned

Observability needs time boundaries as much as error categories.

Where EACI uses this today

Main health assessments use current session evidence and retain older exports as regression references.
