| # Gobstopper benchmark reports |
|
|
| Public aggregate results and protocols from [Gobstopper's compaction studies](https://gobstopper.sh/benchmarks). Use the downloads to inspect selection rules, denominators, retention measurements, recovery tests, and the limits of each historical experiment. |
|
|
| ## Studies |
|
|
| `data/2026-09-19/` contains the retrospective's aggregate results, protocol, and report, plus the separately recorded retention ablation and Apple retention pilot. Keep each experiment's corpus, policy, executable hashes, and limitations with its results. Projected token reduction is an offline estimate. It does not measure provider billing or successful continuation of a task. |
|
|
| `data/2026-09-20/` contains the recovery study's protocol and results. Its synthetic fixture evaluation is separate from the private-session studies. Follow the public reproduction instructions in the protocol and the [source repository](https://github.com/hraness/gobstopper). |
|
|
| The private studies came from one person's machine. Their published aggregates cannot establish performance across other users or independently reproduce the private corpus. Literal string retention does not establish semantic importance or task quality. Historical results describe their recorded implementations, not every later Gobstopper release or request-time proxy strategy. |
|
|
| These downloads form an artifact archive with several JSON schemas. Read individual files using their recorded schema; a combined `datasets.load_dataset` table is not provided. |
|
|
| ## Privacy and provenance |
|
|
| Only the explicitly selected public reports and protocols are included. Private transcript text, session identifiers, local paths, vault snapshots, per-session hashes, and per-session results are excluded. Do not add those files when extending this collection. |
|
|
| `export-manifest.json` records the source commit and SHA-256 of every exported artifact. New completed studies receive new dated folders. Published study files remain frozen; corrections receive a new version with an explanation of the change. See [Gobstopper](https://gobstopper.sh/) for current product behavior. |
