 - Resolve Factory Droid 0.175.0 user hooks through `~/.factory/hooks.json`, the legacy `~/.factory/hooks/hooks.json`, then the user `settings.local.json` and `settings.json` hook containers. Current hook files use a top-level `hooks` object; retain direct event maps as an explicit legacy read contract until Factory migrates them. Register exact `PreToolUse` and `PostToolUse` groups with ten-second absolute command handlers in one active source, preserve the native snake_case payload, and propagate freeze or revocation through exit code `2`. Use PowerShell's call operator with single-quoted absolute arguments and explicit `$LASTEXITCODE` propagation on Windows, and migrate the legacy double-quoted command form through exact ownership checks. Remove exact Elydora ownership from inactive user sources while preserving JSONC comments and unknown event arrays. Keep project, folder, plugin, and organization hook definitions read-only. Resolve local settings over their matching base file, then apply system, project, folder, and user `hooksDisabled` through Factory's extension-only scalar precedence; reject system-managed `allowManagedHooksOnly`. Commit user hook sources, generated runtimes, runtime config, and private key through one rollback-capable transaction, precondition every parsed source and policy file, require exact generated runtime sources during status checks, and require `/hooks` review for the session snapshot and remote organization policy.
 - Resolve Qwen Code 0.20.0 user settings through explicit `QWEN_HOME`, then the initial Qwen home `.env`, then the OS home `.env`; when bootstrap discovers a redirected home, read that home's `.env` as well. Treat empty overrides as unset while preserving their process-level ownership semantics. Read system defaults, user settings, the active trusted workspace, system overrides, and trusted-folder rules with Qwen's documented precedence; write only the user source. Validate the current twenty-one event names and command, HTTP, and prompt handler schemas while preserving future event payloads. Register exact matchless `PreToolUse`, `PostToolUse`, and `PostToolUseFailure` groups named `elydora-guard` and `elydora-audit` with ten-second millisecond timeouts. Preserve the complete native snake_case payload, propagate freeze and revocation through exit code `2`, and use PowerShell's call operator with explicit `$LASTEXITCODE` propagation on Windows.
 - Commit Qwen Code user settings, generated runtimes, runtime config, and private key through one rollback-capable transaction, with snapshot preconditions for every consulted routing, policy, trust, and settings source. Status requires physical files, exact runtime sources, a canonical private key, matching runtime identity, and an effective enabled state. Verify discovery with the official 0.20.0 loader, review `/hooks`, and restart active Qwen Code sessions.
+- Resolve Python Letta Code 0.28.13 global hooks through `${HOME:-~}/.letta/settings.json`, matching Letta's `HOME || homedir()` behavior. Keep Elydora runtimes under the shared CLI root from `os.path.expanduser("~")`, independent from Letta's configurable settings home. Keep the active workspace `.letta/settings.json` and `.letta/settings.local.json` sources read-only, deduplicate the project source when the workspace is the home directory, and apply the official `hooks.disabled` precedence: an explicit global `false` enables hooks, global `true` disables them, then project and project-local `true` values disable them. Validate all eleven current events plus command and prompt handler shapes while preserving future event payloads. Register exact `PreToolUse`, `PostToolUse`, and `PostToolUseFailure` groups with `*` matchers and ten-second millisecond timeouts. Preserve the complete native snake_case payload, propagate frozen or revoked state through exit code `2`, and surface audit delivery failures through stderr, owner-only `error.log`, and exit code `1`; Letta post events retain their documented nonblocking semantics. Use PowerShell's call operator with explicit `$LASTEXITCODE` propagation on Windows and exact two-argument shell commands on Unix. Commit global settings, generated runtimes, runtime config, and private key through one rollback-capable transaction guarded by every consulted source snapshot. Migrate only exact legacy Python command ownership, require physical sources, canonical private keys, exact runtime sources, executable identity, matching runtime identity, and an effective enabled state during status checks, then run `/hooks` and restart active sessions.
