Review a rule book and check runs

Last updated: November 10, 2026

Note

This is a beta feature. Reach out to Nash if you'd like early access.

This walks through reading a rule book and checking your optimization runs against it. For what a rule book holds and what each status and outcome means, see how rule books work.

Open a rule book

  1. Go to Orchestrate ▸ Rule Books. The page opens on a rule book, with its name, the version in use, and the strategies that use it in the header.

  2. To open another one, choose Switch rule book in the header.

If the page reads You can't see rule books, you need permission to view optimization strategies — ask an admin in your organization.

Find a rule

On the Rules tab:

  • Use the filter chips to narrow the list: All, Must, Aim for, Report only, Not in Nash yet, Needs an answer or Confirmed. Each chip shows how many rules it holds.

  • Type in Search rules and wording to match a rule's name, key, or your wording of it and its values.

  • Pick a Site to see only the rules that apply there, each with its value at that site.

If nothing matches, Clear filters brings the full list back.

Read a rule

Select a rule's row to open it. The opened rule shows:

  • Its status — whether it's confirmed and by whom — and its value at each site.

  • How Nash runs it — how Nash reads the rule into planning, for rules Nash carries.

  • In their files and From calls and answers — where the rule came from, with Open the source for files.

  • Confirmations — who agreed to this wording, how and when.

Press Escape, or select the row again, to close it. You can keep several rules open at once.

To change a rule, answer an open question, or confirm a wording, tell Nash. The page doesn't edit rules.

Check a run

The Runs tab appears once a version is published. It lists runs from the last 14 days of the strategies that use the rule book.

  1. Select the Runs tab.

  2. On a run that reads Not checked yet, choose Check against this rule book. Nash grades the run's saved routes against the version in use, and the run opens to show the result.

  3. Read Rules on this run: each rule with its Outcome, the Routes affected, and a Detail. Missed rules come first, then rules Nash couldn't grade.

  4. To grade a run again — for example after a newer version is published — choose Check again.

Select a checked run's line to open or close its result.

Checking a run needs permission to edit optimization strategies. Without it, you don't see Check against this rule book, but you can still read existing checks.

Tip

If you optimize from the drawer with a strategy linked to a rule book, you don't need to check by hand. The drawer's Rule book card checks the run once its routes are saved, and Open in the rule book takes you straight to that run on the Runs tab.

Preview what the rule book changes

On any run, choose Preview changes. What this rule book changes lists:

  • Changes Nash makes to the run's settings — each rule, with how many vehicles it changes.

  • Rules Nash can't plan with yet — rules the preview couldn't apply.

  • Rules it skipped, and why.

If the rule book changes nothing, the preview reads The rule book changes nothing in this run. A preview stores nothing.

Export a version

Choose Export in the header. The version on screen downloads as a JSON file named after the rule book and version — for example east-region-v4.json.
