No independent comparison or exact later availability evidence in this context run.
What difference it made
Comparable benchmark evidence has not been established for this record. Missing results do not imply poor performance.

Assessment
proposed
Manufacturer name is shortened from Intel Corporation; the exact date applies to product introduction only. The availability gap is retained rather than converted into a release date.
Intel says it introduced the first Celeron at 266 MHz on April 15, 1998, but says PCs and boxed processors will be available in the next few weeks.
Open questions and review
Exact first commercial, system, and boxed availability dates remain unknown; no ordering part number.
No owner discrepancy decision is recorded. This does not mean there are no unresolved issues.
scope error · follow up
The expanded cohort spans component introductions; system availability; boxed channels; mobile OEM modules; upgrade reseller availability; and planned system shipments. These are legitimate segment-specific facts but no single availability event can be assumed equivalent across all records.
Intel itself distinguishes introduction from availability in the next few weeks for Celeron 266; the same event-typing separation is required across the expanded cohort.
Follow-up: Maintain typed event and channel fields through human review; do not rank or filter records by a single unqualified release-date column.
Original intake sources
These notes preserve the state at intake. Later verification is shown under Release evidence above; an original note saying verification had not occurred is not the current assessment.
