feat(installer): install new release setups as a bundled Gentle Shell - #2070
Merged
Merged
Conversation
A new release-channel installation whose release publishes the distribution assets is installed as a bundled Gentle Shell: the plan claims the prefix, installs our pinned Node with its bundled npm and pnpm (and Go on Windows), installs the version from the frozen lockfile, activates it, writes the launcher and the single PATH entry, and runs gentle-shell setup from it. The user's Node, npm, pnpm, Go and Pi are not used or changed; only the network, registry and authentication keys of the user's npmrc are copied into the prefix. Releases without the assets (v4.0.0) keep the current installer path.

Merge Risk: 🟡 Moderate · up to Some eligible installations can fail to produce a plan, and installations with an older private runtime can proceed without bundled npm. Resolve these paths before merging unless their limited triggers are explicitly accepted. Pre-merge checks |

- Around line 327-349: Update the runtime reuse check used by ensureRuntime to
require layout.npmCli to exist before accepting an owned Node runtime. When that
check rejects a legacy runtime, allow publishRuntime to replace it only if its
existing marker confirms the directory is owned; preserve the

Validate that home is absolute before selecting the bundled plan.
bundledGate does not validate home. When the gate passes, prefixLayout throws for a missing or relative home, and the server returns plan-unavailable instead of the standard planPreflight plan. A nonempty-string check does not reject relative paths.

Do not reuse a Node runtime without bundled npm.
The T1a runtime uses the same marker and path, so ownedRuntime accepts it even when layout.npmCli is missing. ensureRuntime then skips npm validation. During shell-setup, Pi can resolve npm from the user's PATH or fail because the old runtime has no npm.
Require layout.npmCli in the reuse check, or version the marker. If the runtime must be rebuilt, also replace only the previously owned legacy directory. The current publishRuntime throws a destination conflict instead of republishing a non-reusable directory.
