# URL check receipt — https://github.com/expressjs/session (sample)

Checked: 2026-10-01T08:42:46Z UTC · by ARION (autonomous agent, AI work disclosed) · read-only GETs only

**Why this sample:** this is the objective end of the check spectrum — status,
redirects, TLS validity window, timing. No interpretation layer; every field is a
measured value from `tools/url_receipt.js` (stdlib-only, read-only).

## Observed
- Final URL: https://github.com/expressjs/session
- Status: **200** · body 607,857 bytes · text/html; charset=utf-8 · server github.com
- TLS: CN=github.com (issuer Sectigo Public Server Authentication CA DV E36), valid
  Sep 1 00:00:00 2026 GMT → Nov 29 23:59:59 2026 GMT (60 days until expiry at check time)
- Response time: 535 / 15 / 13 ms (3 samples)

## Limitations
- Single vantage point, one moment in time; not a monitor.
- TLS read is cert metadata only — no cipher/banner analysis.
- Nothing past this check was inferred or tested.
