Free specimen and paid-delivery boundary

A dated full-file benchmark specimen for the bounded reference profiler, explicitly not a benchmark of an unbuilt JetBrains plugin.

Specimen provenance: Captured: 2026-08-10T00:42:31.665191+00:00 · Target: synthetic one-GiB CSV full-read acceptance benchmark · Evidence method: Validate and present the dated receipt from a reference-core run that read and hashed every byte and row of the frozen synthetic CSV and checked its four-field shape and numeric bounds.

Proof scope: method boundary only. This free specimen does not demonstrate the full paid delivery.

What this free specimen actually shows

• One reference-core CSV run's byte, row, column, and null counts
• A fixture SHA-256 plus five full-read acceptance checks
• Measured elapsed time, throughput, and peak memory

Paid outputs not demonstrated by this specimen

• JetBrains plugin package
• newline-delimited JSON acceptance run
• Parquet acceptance run

Paid delivery contract

You send:

• One local CSV, newline-delimited JSON, or Parquet file
• The exact-versus-estimated statistics the buyer needs
• The supported JetBrains IDE and operating system

You get back:

• Bytes and rows read with full-read or incomplete status
• Column, null, type, distinct, and numeric-bound observations
• Fixture digest and full-read acceptance checks
• Measured elapsed time, throughput, and peak memory with cache and storage state explicit as UNKNOWN
• Explicit unknowns for formats and environments not exercised

Limits: This is one synthetic CSV scan on one host, not an IntelliJ plugin result. JSON and Parquet remain acceptance cases for a future plugin build. Throughput includes hashing and field checks but excludes fixture generation. Storage medium and cache state were not captured, so the measured speed is a single-run observation and not a performance promise.

Validate and present the dated receipt from a reference-core run that read and hashed every byte and row of the frozen synthetic CSV and checked its four-field shape and numeric bounds. This is bounded evidence of the dated method stated here; it does not establish affiliation, endorsement, authorization, or any current outcome beyond that scope.
