Version Check

Compare installed and available versions without blocking unrelated work.

Editorially reviewedSource unconfirmed

These examples and illustrative results are independently authored teaching materials, not measured model results.

Use case

A plugin may update while current work can use the installed version. Teaching versions are installed 1.9.0 and trusted stable 1.10.0, not actual product facts. Availability and replacement are separate operations.

Mechanism

Inspect identity/version, permitted trusted release metadata and channel with a bound. Compare through supported parsing, not string order. Network/format failures leave availability unknown and installation intact. Updating follows its own scope/compatibility/reversal checks.

Bad example

Replace installed files with latest main, compare versions lexically or report no update after a failed query.

Good example

Verify teaching 1.9.0/stable 1.10.0 and use semantic parsing to report availability with source/channel. Beta-only follows stable-channel policy, not a stable claim. Timeout/ambiguous identity/format remains unconfirmed while usable installation stays. Replacements need actual authorization/compatibility.

Why the change matters

Version checks inform freshness without mutating environment. Parsing/channels prevent incorrect ordering, and failed queries do not become no-update facts.

Observable expectation

The fixture identifies stable 1.10.0 above 1.9.0, does not automatically select beta and preserves installed bytes on network failure.

Inspect identity/source/method; no real plugin is queried/installed.

Limits

Non-semantic versions require product rules. Numbers/signatures/dates alone prove neither compatibility nor defect absence. Provenance is unconfirmed and global settings are not silently changed.
