section 1:

The error capture record maintains the specifics of the first illegal access detected, except if the
following two conditions are held: (1) any interrupt-suppress bit regarding the access is set, and (2) no
bus error is returned.

section 2:

If a transaction violates IOPMP rules on multiple non-priority entries which don’t suppress interrupt or
bus error response, the ERR_REQID.eid should be one of the entries.

The error capture record maintains the specifics of the first illegal access detected, as stated in Section 1, regardless of whether the access corresponds to priority or non-priority entries. For non-priority entries, this record captures the specifics of the first illegal access detected, which is clear. However, Section 2 states that the ERR_REQID.eid should be one of the non-priority entries that violated the IOPMP rules and do not suppress interrupts or bus errors.

This creates ambiguity: while the error capture record holds details of the first illegal access, the ERR_REQID.eid might not correspond to the first entry but to any of the violating entries. Shouldn’t the captured ERR_REQID.eid also belong to the first illegal access entry, for consistency?

The error record records the first illegal access information. The illegal access can violate multiple non-priority entries. Therefore, all violated entries belong to the first illegal access and candidates of ERR_REQID.eid are described on section 2 you commented.
