Per discussion: "test" and "eval" overlap in meaning; "simulations" is more honest about what's actually happening — scripted plant inputs driving a physics sim, then recorded for analysis. Rename scope: - eval/ → simulations/ (tracked as git renames) - Internal references in run.js and README.md updated - wiki/modes/mpc.md link updated Also fixes a log-write bug noticed during the rename: - run.js didn't mkdir simulations/logs/ before createWriteStream, so the stream opened into a potentially non-existent dir and the file never materialised. Added fs.mkdirSync(..., recursive:true). - end() wasn't awaited, so the process could exit before the stream flushed. Now awaits the 'finish' event. Confirmed: 1200 records actually land in simulations/logs/<scenario>.jsonl. - Added simulations/logs/.gitignore so future JSONL artefacts stay out of the repo but the dir remains tracked.

Control modes
Each page describes one pumpingStation control mode and how it uses the shared basin model — specifically, how it uses the three control thresholds (minLevel, startLevel, maxLevel) and computes the demand it sends to the MGC.
The two safety thresholds (dryRunLevel and overflowLevel) are mode-independent and are enforced by the safety layer outside any mode. They never appear in a mode's policy.
Template
Every mode page follows the same structure:
- At a glance — one sentence + small fact table (inputs, output, status)
- Diagram — one or more, per tier (see below)
- Inputs — what signals the mode reads
- Threshold policy — how it uses / adjusts
minLevel,startLevel,maxLevel - Demand formula — pseudocode for Tier 1/2, objective function for Tier 3
- Edge cases — cold start, sensor dropout, interaction with safety layer
- Related — links to other modes + functional description
The three tiers classify modes by how dynamic the decision surface is:
| Tier | Curve | Example modes | Diagram type |
|---|---|---|---|
| 1 — static | Memoryless demand = f(x); single curve |
levelbased, manual |
Single-curve transfer function |
| 2 — parameterised | Shape fixed, curve moves with θ(t) | flowbased, pressureBased, percentageBased, powerBased |
Transfer function + parameter overlay / family |
| 3 — horizon-based | Optimisation, no fixed curve | hybrid-optimal, mpc, weather-aware |
Block diagram of signal flow + scenario time-series |
