 ## Plugin Configuration
 [plugins]
-# Directory containing WASM plugin files
-# Default: <data_dir>/plugins
-# directory = "~/.local/share/pinakes/plugins"
-
-# Enable plugin system (experimental)
-# NOTE: The plugin system has not been finalized, and the API is subject to change.
-# Please report any bugs, and expect breaking changes.
+# Enable plugin system
 # Default: false
 # enabled = false
 
+# Directories to scan for plugins (each containing a plugin.toml + .wasm binary)
+# Default: []
+# plugin_dirs = ["/etc/pinakes/plugins", "~/.local/share/pinakes/plugins"]
+
+# Allow loading unsigned plugins (disable in production to enforce signatures)
+# Default: false
+# allow_unsigned = false
+
+# Hex-encoded Ed25519 public keys trusted for plugin signature verification.
+# Plugins must ship a plugin.sig (Ed25519 signature over the BLAKE3 hash of the
+# WASM binary). If allow_unsigned is false and no trusted keys match, the plugin
+# is rejected.
+# Default: []
+# trusted_keys = [
+#   "a1b2c3d4e5f6...64_hex_chars...",
+# ]

+# Maximum concurrent plugin operations (e.g., parallel metadata extraction)
+# Default: 4
+# max_concurrent_ops = 4
+
+# Global plugin timeout in seconds (legacy, prefer per-tier timeouts below)
+# Default: 30
+# plugin_timeout_secs = 30
+
+# Circuit breaker: auto-disable a plugin after this many consecutive failures
+# A successful call resets the counter. Reload or toggle to re-enable.
+# Default: 5
+# max_consecutive_failures = 5
+
+# Per-tier timeout configuration
+# [plugins.timeouts]
+# Timeout for capability queries (supported_types, interested_events, can_handle)
+# Default: 2
+# capability_query_secs = 2
+#
+# Timeout for processing calls (extract_metadata, generate_thumbnail)
+# Default: 30
+# processing_secs = 30
+#
+# Timeout for event handler calls (handle_event)
+# Default: 10
+# event_handler_secs = 10

 ## Transcoding Configuration
