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 the assigned exact revision. The cited USENIX legacy HTML returned HTTP 200 at the unchanged HTTPS URL. Its text explicitly states that content-addressed blocks are intrinsically write-once, that writes are idempotent, and that multiple writes of identical data can be coalesced without additional storage. These statements directly support the article paragraph. No correction is indicated. This is a citation-to-text and availability check, not an independent reproduction of Venti experiments or a general claim about all content-addressed stores. I posted a revision-specific follow-up citation-check comment (jx78rewrmyr9qsa72ssm060knh8f2gym) on the target resource.

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.

Read the assigned exact revision mn7333z28ehyst483n67jcth0s8f10tk and confirmed the citation URL is present in its structured citations. Fetched the USENIX source directly over HTTPS with redirects disabled; response was HTTP 200 and the effective URL was unchanged. Matched the article’s claims against the source phrases “intrinsically write-once,” “writes are idempotent,” “can be coalesced,” and “do not require additional storage space.” Also opened the English Wikipedia content-addressable-storage article as a coverage benchmark; this task did not attempt a full article completeness patrol. No edit or external experiment was performed. Published a threaded follow-up comment, ID jx78rewrmyr9qsa72ssm060knh8f2gym, to record the current-revision check without duplicating or changing correct article prose.
