4) Pin / terminal information extracted from the datasheet

The datasheet clearly states:

Contact form is SPDT (1c)
Coil has no polarity
The package variant uses an 8-hole pattern

What is not cleanly recoverable from text extraction alone is a fully trustworthy per-pin functional map for all 1...8 pin numbers. The terminal diagram is present in the PDF, but the extracted text for exact pin-role mapping was inconsistent across passes. Because of that, I cannot certify the current numbered terminal mapping from text extraction alone.

5) Cross-check: symbol and footprint vs datasheet

Table

Check	Result	Risk
MPN matches part description	Pass	Low
Coil voltage matches description	Pass: 12 VDC	Low
Contact form matches description	Pass: SPDT / 1 Form C	Low
Symbol pin count vs datasheet hole count	Pass: symbol has 8 terminals, datasheet says 8 holes	Low
Footprint existence	Pass	Low
Exact footprint drill / pitch geometry vs datasheet	Not fully verifiable from available layout data	Medium
Exact symbol pin-number-to-function mapping vs datasheet	Not verified	High
Symbol electrical pin typing	All pins are Unspecified	Medium
Symbol style	Implemented as separate terminals, not a conventional relay symbol	Medium

Flagged issues High-risk issue

The current symbol’s functional terminal naming and numbering cannot be confirmed against the datasheet’s terminal arrangement with enough confidence from the extracted PDF text.
If even one of COIL_1, COIL_2, COM_1, COM_2, N.O._1, N.O._2, N.C._1, or N.C._2 is assigned to the wrong pin number, that can cause:
- wrong PCB wiring
- incorrect relay behavior
- possible board failure in use

Medium-risk issues

All symbol pins are typed as Unspecified rather than coil/contact-related electrical types.
The footprint appears present and the pad count matches, but I could not retrieve enough layout geometry to prove the exact hole positions and pitch match the datasheet.
Using eight independent terminal symbols instead of a relay symbol makes review harder and increases the chance of pin-mapping mistakes.

Bottom line

The metadata is mostly consistent with the datasheet.
The biggest unresolved manufacturing/function risk is the exact pin-number mapping between the schematic symbol and the datasheet terminal diagram.
The footprint likely has the correct 8-pin through-hole pattern, but exact geometry could not be fully confirmed from the available layout data.

If you want, I can next help you turn this into a precise correction checklist for the part so the symbol and footprint can be verified pin-by-pin against the datasheet figure.
