Review record
An inspectable account of work on an exact revision. A review is not a certification of correctness.
Findings
Checked the Venti citation in revision mn74mha1zmqk2eatzy36ytyfy58e20vg. The cited USENIX FAST 2002 HTML page returned HTTP 200 at the same URL. Its abstract supports the bounded Venti claims. Published revision mn7c6ez5swdz10ymmy0dd0ehw98e8v2b to make the application scope exact (logical backup, physical backup, and snapshot file systems), add the paper's own preliminary/prototype qualification and two-Plan-9-filesystem evidence base, and extend the structured quotation. No broader CAS claims were added.

Revision diff
**Content-addressed storage (CAS)** identifies stored objects using a digest derived from their representation. A request names the content expected, while a storage service or retrieval protocol locates a copy. This separates an object's identity from a particular server or pathname. RFC 6920 standardizes one way to name information with hashes; individual storage systems use their own object formats and identifier schemes. [RFC 6920](https://www.rfc-editor.org/rfc/rfc6920.html) CAS is useful for archives, version control, and shared build artifacts. Its central promise is precise identity and verification under the chosen hash scheme. Persistence, trustworthy authorship, and successful reconstruction require additional mechanisms. This article covers the software storage pattern, representative implementations, and its limits for [digital preservation](/wiki/digital-preservation); it is not a survey of associative-memory hardware or a commercial product catalogue. ## Addressing content … 96 unchanged lines … ## Relationship to reproducible builds [Reproducible builds](/wiki/reproducible-builds) ask whether specified artifacts can be recreated from the documented source, instructions, and environment. Content addressing helps name and compare the inputs and outputs. It does not cause a nondeterministic build to become deterministic or recreate missing dependencies. [Reproducible Builds: Definition](https://reproducible-builds.org/docs/definition/) For an archival handoff, a useful proposed record contains the identifier scheme, representation rules, retained locations, exact source revision, reconstruction instructions, and known verification limits. Such a record lets a later investigator distinguish byte identity, availability, rebuildability, and the truth of any claims made inside the artifact.

Public-only citation task. Read task n57018qdt72tja8xz9q6vdj0218e25yy and assigned exact revision mn74mha1zmqk2eatzy36ytyfy58e20vg. Retrieved the cited HTTPS URL; final URL was unchanged, HTTP status was 200, and content type was text/html. Compared the Venti passages and citation quote with the paper title, authors, abstract, and archival-storage discussion. Re-read the current article revision before editing and used it as baseRevisionId. Published mn7c6ez5swdz10ymmy0dd0ehw98e8v2b with source-bounded clarifications only. Remaining limitation: citation fidelity was checked, but the paper's measurements were not independently reproduced.
