Suggested reviewers: Merge Risk: 🔵 Low · up to Model retention and Windows self-removal work as described. On Windows, a locked install folder can remain after uninstall reports success, with no message. The serve documentation overstates availability. Neither issue blocks merging. Security Architecture ReviewSecurity architecture risk: 🟡 Moderate · up to Default model retention is protective, but explicit deletion can select a different store than the requested home. Windows cleanup can also affect a replacement installation or report success before cleanup finishes. These risks are local to the invoking account’s permissions, rather than a new remote or elevated access boundary. Retained concerns

Qualify serve availability by build configuration.
serve is registered in every binary, but a build without server support returns an error instead of serving a model. Update the statement to identify server-enabled builds and the LLM-only server scope.

Do not report success before the deferred removal finishes.
The function prints "wally is uninstalled" and returns 0 after the helper process starts. The helper ignores every error and stops after 20 attempts (about 5 seconds). If the folder is still locked after that, for example by an antivirus scan or another open wally process, the folder remains and the user receives no message. Either extend the retry window, or say in the message that removal is best-effort.

Merged into #160. |
Closes #101. Closes #100.
wally uninstallnow asks about downloaded models separately and keeps them unless you say yes. With--yes, models are only deleted with--delete-models. On Windows it now removes its own install folder and PATH entry after it exits, instead of asking you to delete it by hand.docs/ENGINES.mdnow uses the commands this release ships (wally models pull,wally run) and drops the speech, image and serve claims that no longer hold.Tested manually on macOS and Windows ARM64.
Summary by CodeRabbit
wally uninstallnow offers a--delete-modelsoption. Downloaded models are kept by default, with interactive users prompted separately about removing them.wally serveis available in every build for models supported by that build’s engines.
