 abcd ahoy classifies a repo with a partial or stray .abcd/ as folder_kind managed-repo even when adopted is null and index_registered is false -- managed reads as abcd manages this when it only means abcd could. No folder_kind value distinguishes a stray .abcd/ built by another workflow from an abcd-adopted repo. Observed on Manuscripts, whose .abcd/development/ was hand-built with zero abcd involvement yet is reported managed. Related: iss-62 managed-repo-identity-gate. Detector: a folder_kind vocabulary that separates adopted from merely-abcd-shaped; acceptance is ahoy --json on a hand-built .abcd/ not reporting managed.

 ### Fixed
 
+- **`abcd ahoy` no longer overclaims `managed-repo` for a stray `.abcd/`
+  directory (iss-88).** Folder classification treated the mere presence of an
+  `.abcd/` directory as a strong managed signal, so a repo with an unregistered,
+  markerless `.abcd/` reported `managed-repo`. Only index registration or a
+  marker block now promotes a folder to managed; a stray `.abcd/` reports
+  `unmanaged-repo` (or `unmanaged-folder` outside a git repo).
 - **`abcd intent "<text>"` no longer files a draft from a mistyped subcommand.**
   A near-miss for an intent subverb (`intent paln`, `intent lnk itd-5`) is
   refused with a did-you-mean and writes nothing, mirroring `abcd capture`'s
