+ * STANDING ORDER's detention fight, measured into an artifact instead of typed into prose.
+ *
+ * The Controller sends the wardens in Act Two, and the GM needs to know before it happens
+ * how likely the party is to end up in the Sump. This is pack-tables.mjs's arrangement for
+ * a second scenario: the configs are the rows the document prints, the party is the cast
+ * the document declares, and a citation addresses one figure.
+ *
+ *   node tools/detention-tables.mjs            print the table
+ *   node tools/detention-tables.mjs --update   re-record tools/detention-baseline.json
+ *   node tools/detention-tables.mjs --check    hold the record against the game (in npm run check)
+ *
+ * NOT named scenario-something: check-scenarios sweeps `tools/scenario-*` into the scenario
+ * corpus, and this file's prose is not a scenario's.
+ *
+ * WHAT THE FIGURES ARE. runFight does not model restraint. A warden in the document stops
+ * hitting an agent who is down and cuffs them; in the harness he keeps swinging. So `wiped`
+ * is "the whole party detained" and is sound, while `deaths` is a CEILING — the fight with
+ * nobody holding back and nobody treating the fallen — and the document must say so beside
+ * any death figure it prints.
