## Summary
Adds an admin upgrade-status panel that surfaces per-instance and
per-workspace migration health, backed by a Redis-cached aggregate to
keep the page snappy on large fleets.

## Computed metrics
**Instance** (`InstanceUpgradeStatus`)
- `inferredVersion` — version derived from the latest non-initial
instance command name
- `health` — `upToDate` | `behind` | `failed`, derived from the latest
attempt vs. the last expected instance step in the upgrade sequence
- `latestCommand` — `{ name, status, executedByVersion, errorMessage,
createdAt }` from the most recent attempt
**Per-workspace** (`WorkspaceUpgradeStatus`)
- `workspaceId`, `displayName`
- `inferredVersion`, `health`, `latestCommand` (same shape as instance),
computed against the latest expected step in the sequence
**Aggregate** (`AllWorkspacesUpgradeStatus`, only across `ACTIVE` /
`SUSPENDED` workspaces)
- `instanceUpgradeStatus`
- `totalCount`, `upToDateCount`, `behindCount`, `failedCount`
- `workspacesBehindIds[]`, `workspacesFailedIds[]`
- `computedAt`
## Fetching strategy
All reads go through `UpgradeStatusCacheService` (cache namespace:
`EngineHealth`).
- **Aggregate read** (`getAllWorkspacesStatus` →
`getAllWorkspacesUpgradeStatus` query):
reads summary + behind-ids + failed-ids in parallel; if any of the three
keys is missing, full recompute (`recomputeAllWorkspaces`) is triggered,
which also primes per-workspace entries.
- **Per-workspace read** (`getWorkspacesStatus(ids)` →
`getUpgradeStatus(ids)` query):
`mget` on workspace keys; misses are recomputed individually
(`recomputeWorkspace`), and aggregates are reconciled in place (count +
id list deltas) without a full recompute.
- **Recompute on demand**: `refreshUpgradeStatus` mutation calls
`recomputeAllWorkspaces` to bypass cache and rewrite all keys.
- **Auto-invalidation**: `InstanceCommandRunnerService` (fast + slow
paths) and `WorkspaceCommandRunnerService` invalidate after every run
via `safeInvalidateUpgradeStatusCache()`
(`flushByPattern('upgrade-status:*')`). Failures in cache invalidation
are swallowed and logged so they never break the migration runner.
- **TTL**: `60 * 60 * 1000` ms (1 hour) on every key — protects against
stale data even if a runner crashes before invalidating.
## Introduced cache keys
All under the `EngineHealth` cache-storage namespace:
| Key | Type | Purpose |
| --- | --- | --- |
| `upgrade-status:all-workspaces:summary` |
`CachedAllWorkspacesStatusSummary` | Counts + instance status +
`computedAt` |
| `upgrade-status:all-workspaces:behind-ids` | `string[]` | Workspace
ids in `behind` state |
| `upgrade-status:all-workspaces:failed-ids` | `string[]` | Workspace
ids in `failed` state |
| `upgrade-status:workspace:<workspaceId>` |
`CachedWorkspaceUpgradeStatus` | Per-workspace status (one key per
workspace) |
Full invalidation uses the pattern `upgrade-status:*`.
## Index added on `upgradeMigration` (already added on prod)
Migration
`2-2-instance-command-fast-1777308014234-addUpgradeMigrationWorkspaceIdIndex.ts`:
```sql
CREATE INDEX "IDX_upgradeMigration_workspaceId_name_attempt"
ON "core"."upgradeMigration" ("workspaceId", "name", "attempt")
WHERE "workspaceId" IS NOT NULL;
