Add comprehensive test coverage for upgrade semantics: - 12 Python unit tests for store migration (forward-only, downgrade refusal, idempotent behavior) across migrate_to_latest, init_store, and open_store_readonly - Enhanced packaging upgrade test to verify all five acceptance criteria: snapshot before migration, store not rebuilt, config survival, timer/removal no-ops during upgrade - RPM-specific test for config file preservation (noreplace conffile) Co-authored-by: CommandCodeBot <noreply@commandcode.ai>

"""Packaging acceptance tests — containerized matrix.
|
||
|
||
Tests the built deb and rpm packages in throwaway per-distro containers,
|
||
verifying the dormant-install contract, upgrade semantics, removal mapping,
|
||
and migration guard. This is the single test seam agreed in the release spec.
|
||
|
||
Requirements:
|
||
- docker (running, current user in docker group)
|
||
- Built packages in dist/ (run `make package` first)
|
||
- No network access required once containers are built
|
||
- No registry or signing key required
