 # Completed Steps
 
+- 2026-10-04: An unlocker's ID is the name of its directory in `unlockers.d`,
+  so no two unlockers of a vault share one
+  (https://git.eeqj.de/sneak/secret/issues/98). Before, a keychain or Secure
+  Enclave unlocker's ID was its creation time to the minute and the host name,
+  and a passphrase unlocker's the time to the minute, so two created within a
+  minute shared an ID, and `unlocker select`, `unlocker remove` and the
+  selection `unlocker add` makes acted on the older one. A PGP unlocker's ID
+  was `pgp-` and its key's fingerprint; a second PGP unlocker for a key is
+  still refused, now by comparing the fingerprint in the other unlockers'
+  metadata. `unlocker list` and the shell completion of `unlocker select` and
+  `unlocker remove` take each ID from the directory the unlocker was read
+  from, no longer by matching metadata, so two unlockers with the same
+  metadata are listed apart; an unlocker of an unknown type is listed under
+  its directory name, and completion now offers Secure Enclave unlockers too.
+  The keychain and Secure Enclave code was type-checked by
+  `script/lint-darwin`, never run; a test on Linux lists, completes, selects
+  and removes each of two passphrase unlockers with the same metadata by its
+  own ID.
