Subject: dotfiles

Shell, editor and terminal configuration, the tools that go with them, and
szecret, an age-based secret manager whose store lives elsewhere.

History restarts here. What came before was not written to be read by
anyone else, and carried machine names, addresses and an encrypted secret
store; it is kept privately instead. What is left is meant to be safe on
any machine, including one whose owner is not me: see CLAUDE.md for the
rule it is written to.

+get-local: Retrieve and decrypt a secret from a localized store
+
+Decrypts and outputs a secret value from a localized store. The store name
+is read from the .szecret metadata file in the file's directory.
+
+Usage:
+  get-local <file-path>
+  get-local -h|--help
+
+Arguments:
+  file-path    Path to the encrypted file to decrypt
+
+The command will:
+1. Read the store name from <directory>/.szecret
+2. Retrieve the local store's private key from global store
+3. Check if the encrypted file exists and is readable
+4. Decrypt the file using age with the local store's private key
+5. Output the decrypted content to stdout
+
+Legacy usage (deprecated):
+  get-local <local-store-name> <file-path>
+
+Note: Exits with error if file doesn't exist or decryption fails.
