Long-term: dedicated DB host or Server 2019 migration. Note: misleading instance name burned ~1 day of triage — do NOT stop SQLEXPRESS thinking it's idle.

The cap stops the trim cycle even when global pressure rises, because SQL voluntarily stays under the ceiling instead of getting forcibly trimmed.
2. **Confirm Station 1's hostname / IP** with Leslie. None of the active SQLEXPRESS sessions matched `IMC-STATION1` exactly. Likely either `DESKTOP-44L80C0` / `DESKTOP-MR3ALTK` (un-renamed boxes) or a station that was disconnected at check time.

Likely either `DESKTOP-44L80C0` / `DESKTOP-MR3ALTK` (un-renamed boxes) or a station that was disconnected at check time.~~ **Resolved 2026-05-06 by Howard:** Station 1 = `IMC-STATION1`, IP **192.168.0.50**. It wasn't in the active connection list at enumeration time — consistent with it being disconnected after the user-facing error and not yet reconnected at our snapshot. For next recurrence, target diagnostics by `client_net_address = '192.168.0.50'` in `sys.dm_exec_sessions` and by remote IP in SQLEXPRESS connection events.
3. **Locate AIMSQL `.mdf` files** before any consolidation talk. They weren't where I expected. Worth a 5-minute filesystem search.
4. **Schedule SQLEXPRESS-targeted restart cadence** only if the memory cap doesn't hold — but it's after-hours-only because every register would briefly disconnect.
