test: add cross-version upgrade e2e — install prior release, upgrade to HEAD (#830) - #842
Merged
Conversation
…to HEAD (#830) Nothing else in the suite proves an existing installation survives volute update. This is the enforcement mechanism behind the migration-history fix (#713) and the "DB always migrates forward" promise. The test: 1. Installs the *previous published release* (npm artifact, not rebuild) into a scratch VOLUTE_HOME 2. Populates real state through the prior daemon's API: creates a mind from that release's template, adds a schedule, sends a message, starts the mind 3. Boots the working-tree daemon against the same VOLUTE_HOME (the upgrade) 4. Asserts state survived: - Migration count matches working-tree drizzle/*.sql - Mind auto-restores to running - Message reads back - Schedule intact - volute mind upgrade of the prior template merges cleanly Prior version = highest volute-v* git tag below HEAD (deterministic, local tags), overridable via VOLUTE_UPGRADE_FROM. Skips gracefully when the prior release can't be obtained (no tags, offline, first release) so it never breaks CI. Adds npm test:upgrade and a CI job with fetch-depth: 0 (tags needed).

Summary
Nothing else in the suite proves an existing installation survives volute update. Yet once Volute has outside users, every release is an upgrade executed on a strangers populated machine — and the update path is the only channel for shipping fixes.
This is the enforcement mechanism behind the migration-history fix (#713) and the DB always migrates forward promise.
