+ * The implementation body is deliberately unchanged by #1295 — only this comment
+ * is new. The scanner is line-based and string-unaware, so it ends the table at
+ * the first line matching `/^\s*\[/` even inside a multi-line value. Twenty call
+ * sites in this file consume its output, most of them by matching a regex
+ * against the returned text, so widening that text changes what they match. An
+ * earlier attempt at #1295 made this scanner string-aware and thereby gave
+ * `getAgentsEnabled`, `getAgentsMaxDepth`, and `getMaxConcurrentThreads` three
+ * new wrong answers.
+ *
+ * The readers that matter for #1295 use a real TOML parse instead (see
+ * `parsedTomlTable`). This stays as the fallback for documents that do not
+ * parse, and as the reader for the remaining call sites until they are migrated
+ * the same way.
