-### Fixed
-
-- fix(security): wire `ShadowProbeExecutor` into the agent executor chain (`src/runner.rs`).
-  `ShadowSentinel` is now instantiated when `security.shadow_sentinel.enabled = true` and
-  inserted between `ScopedToolExecutor` and `PolicyGateExecutor` as required by spec 050 §Phase 2.
-  Adds `ShadowSentinelProbeGateAdapter` bridge to avoid circular crate dependency. Wires
-  `sentinel.advance_turn()` into `begin_turn()`. Closes #3739.

-- fix(hooks): `pre_tool_use` hooks now fire for tool calls intercepted by the utility gate;
-  previously the hook block was skipped because `check_call_gates` returned early with `continue`.
-  Closes #3738.
-- fix(tui): parallel tool call output no longer gets cross-contaminated in the TUI. `tool_call_id`
-  is now threaded from `ToolCall` through `ShellExecutor` → `ToolEvent::OutputChunk` →
-  `tui_bridge` → `AgentEvent::ToolOutputChunk/ToolStart/ToolOutput`. The TUI uses id-based
-  lookup when `tool_call_id` is non-empty; on miss it drops the chunk with a `warn!` log
-  instead of falling back to the last streaming message (which was the source of the bug).
-  The legacy empty-id path retains the old `rposition` fallback for backwards compatibility.
-  Closes #3688. (#3708)
-- fix(tui): `handle_diff_ready` now correlates diffs to tool messages by `tool_call_id` instead of
-  a position-based `.rev().find()` scan, preventing diffs from attaching to the wrong message when
-  multiple tool calls are in flight. `AgentEvent::DiffReady` is now a struct variant carrying
-  `tool_call_id: String`. `ToolOutputChunk` lookup similarly uses id-based matching with a fallback
-  to the last streaming Tool message for shell tools whose `ToolEvent::OutputChunk` lacks an id.
-  `Channel::send_diff` gains a `tool_call_id: &str` parameter. (#3711)
-
-- fix(cli): `zeph cocoon doctor` now reports `[FAIL]` for `cocoon_client_url` with an invalid scheme
-  (e.g. `ftp://`). `check_config_present` previously returned `[OK]` without calling

   New `[[hooks.pre_tool_use]]` and `[[hooks.post_tool_use]]` config sections accept
   `HookMatcher` entries (pipe-separated tool name patterns). Hooks fire with env vars:

   and `ZEPH_TOOL_DURATION_MS` (post hooks only). PreToolUse fires before the `RuntimeLayer`
   permission check (observers see all attempted calls). Hook dispatch is fail-open at the agent
   level; `fail_closed` in a `HookDef` aborts the hook-chain sequence only. Closes #3698.
-
 - feat(tui): native terminal text selection without Shift modifier. `EnableMouseCapture` replaced
   with alternate-scroll mode (`\x1b[?1007h`/`\x1b[?1007l`) so the terminal translates scroll-wheel
   events into arrow keys. Chat scrolling is preserved; `AppEvent::MouseScroll` removed from the
   event model. Panic hook updated to emit `DisableAlternateScroll` on crash. Closes #3685. (#3685)
-
 - feat(tui): clipboard shortcuts for copying assistant replies. New `clipboard` module with
   `ClipboardHandle` backed by arboard (local) with OSC 52 fallback (SSH/tmux). SSH detected via
   `SSH_TTY`, `SSH_CONNECTION`, `SSH_CLIENT`. `Ctrl+O` and `/copy` slash command copy the last
   assistant message to clipboard. `clipboard` feature flag (default-on) gates the arboard
   dependency for headless builds. Closes #3685. (#3685)

 - feat(tui): Two-tier tool rendering and `ToolDensity` config — replaces the boolean
   `compact_tools` toggle with a three-state `ToolDensity` enum (`compact` / `inline` / `block`)

   sidecar connectivity checks. Runs 6 ordered checks: config entry presence, sidecar HTTP
   reachability (`GET /stats`), proxy connection, worker count, model listing, and vault key

   emits a structured JSON envelope with `schema_version: 1`. Requires `cocoon` feature. (#3672)
