tui: styled filesystem find + find_up output — stage 3 ...

find: the "[N matches for 'pattern' in path ⠠ …]" header plaque is dim
(warning color on ⠠ truncated); "No matches for …" renders dim; each match
line "{path}  ({size})" renders the path in text, "  (" and the size in
dim, and the "<dir>" marker in info.

find_up: a resolved path renders in accent; "not found (searched: …)"
renders dim.

Fallback narrowed to write/edit/append/move/copy/delete/mkdir/exists/
query/unknown. 5 new tests (find header/matches/truncated/no-matches,
find_up found/not-found); 29 filesystem-renderer tests total. Full suite
814 passed, 1 skipped.

tui: styled filesystem read + info output — stage 2 ...

read: the "[path  |  N lines  |  size]" header plaque is now dim with the
path highlighted in accent (offset/limit plaque "… lines A–B of N …"
likewise); the "⚠ Large file …" warning line renders in warning color; the
file body renders in text (was dim — readable now) with no syntax
highlighting (rejected by design); numbered reads dim the line numbers and
render line content in text. read errors (not_found, file_too_large) render
in tool_error.

info: each "key:     value" line highlights the key (incl. colon) in accent,
the alignment padding in dim, and the value in text.

Fallback narrowed to write/edit/append/move/copy/delete/mkdir/exists/find/
find_up/query/unknown (statuses and find/query intentionally untouched).
Diff/list/grep from stage 1 unchanged.

6 new tests (read plaque/offset/warn/numbered/error, info keys+values);
24 filesystem-renderer tests total. Full suite 809 passed, 1 skipped.

tui: styled filesystem tool output (diff / list / grep) — stage 1 ...

The TUI rendered every tool result as a single dim Text in a Panel — no
special handling for filesystem, so unified diffs from edit_lines/smart_edit/
diff were shown as plain grey text (the existing DiffRenderer only fires on
type:"diff", which filesystem never emits), directory listings were an
unaligned text blob, and grep matches had no pattern highlighting.

New FilesystemToolResultRenderer (clients/terminal/tui/renderers/filesystem.py)
intercepts filesystem tool_call events by tool=="filesystem" + args.action:

- diff / edit_lines / smart_edit: reuse a shared highlight_unified_diff()
  helper (extracted from DiffRenderer) — + green, - red, @@ dim; the
  "Applied …" summary line of edit_lines/smart_edit is separated from the
  diff body via a Group; "Files are identical." renders dim.
- list: header plaque dim (warning color on ⚠ truncated); directories
  shown as "▸ name/ (n items)" in info color; files as name (text) +
  size (accent) + time (dim), preserving the tool's fixed-width alignment;
  "?" entries in warning; "(empty directory)" dim.
- grep: header plaque dim; "rel:line:" location dim; matched pattern
  occurrences highlighted in accent (case-insensitive, re.escape'd);
  "No matches …" dim.
- read / info / write / edit / append / move / copy / delete / mkdir /
  exists / find / find_up / query / unknown: plain dim fallback (unchanged
  for now — stage 2). Errors (success=False): plain in tool_error color.

Registered before the generic ToolResultRenderer (first-match wins). The
filesystem tool, WS protocol, events, and webclient are untouched.

22 new tests in tests/clients/test_filesystem_renderer.py cover accepts,
diff/edit_lines/identical/error, list (dir/file/truncated), grep
(pattern/no-matches/no-pattern-arg), fallback, title+status, subagent
indent. DiffRenderer behavior unchanged (existing test still passes).

Navi Code TUI: show context-compression summary in the chat ...

The server already sent the summary text in ContextCompressed.summary, but the
TUI never showed it — forced /compact printed a bare "N → M messages" line and
mid-turn auto-compress produced no chat feedback at all. Now both render a
distinct bordered block headed "Context compressed: N → M messages" with the
summary text (markdown) inside, so the user can see what the compressor kept.

- chat_model: new context_summary kind; context_compressed creates a chat item
  carrying the summary + before/after counts (was explicitly ignored).
- renderers/summary: ContextSummaryRenderer — dim bordered panel, markdown body.
- chat_panel: _item_msg mapping for context_summary.
- tui_app: emit the summary item on context_compressed for both forced and
  mid-turn cases; drop the now-redundant one-line status (the block header
  carries the counts). Spinner start/stop/label logic unchanged.
- Tests: chat_model mapping + renderer (accepts/counts/text/missing-counts).

Summaries are live-only — not rebuilt on session reload (the compressor stores
them is_display=False, same as before for compression events).

tui: show the changed step's text in the todo update call card ...

The todo update call card (→ todo · #3 → done) now shows the text of the
step being changed, plus the validation when present. The LLM's update args
carry only the index, not the task text, so the text is read from the
current plan row before the tool runs and attached to ToolStarted.metadata
(client-rendering only, backward-compatible).

Backend:
- events.ToolStarted gains a metadata dict (mirrors ToolEvent) → to_wire.
- navi/tools/todo: step_text_for_update(index, ctx) resolves the step text
  via _sid/_uid (so sub-agent isolation holds), started_metadata_for_call
  wraps it for both emit sites.
- agent.py (parent) and subagent_runner.py (sub-agent) enrich ToolStarted
  via the shared helper before emitting.

Renderer:
- TodoStartedRenderer update card reads msg.metadata.step_text → shows the
  step text + validation; falls back to 'no validation' on history replay.
- Removed the step-text line from the result card (it now lives in the call
  card) — result card is back to the compact 'plan · X/N done' summary.

Navi Code TUI: show request duration (live timer + chat metadata) ...

Live elapsed timer next to the activity indicator (ticks once per second
during a turn, format 2m 16s), driven by the same stream_start/stream_end
hooks as the activity indicator — so it spans the whole turn (all LLM calls,
tool calls, planning, sub-agent steps). On stream_end it syncs to the
backend's authoritative elapsed_seconds before freezing; on stream_stopped/
error/disconnect it freezes at the locally-measured value.

On stream_end the model also appends a turn_meta ChatItem rendered as a dim
"⏱ 2m 16s" line below the answer — the total time the agent spent on the
user's request. The value comes from stream_end.elapsed_seconds, already
measured by the backend over the whole turn, so the TUI needs no timer for
accuracy. stream_stopped/error do not get a metadata line (only completed
requests).

Shared format_duration(): None -> "—", <60s -> "16s", <3600 -> "2m 16s",
>=3600 -> "1h 2m".

tui: render Navi's answers as markdown ...

AssistantMessageRenderer now parses its content as markdown (headings, lists,
bold/italic, inline and fenced code blocks with theme-aware syntax
highlighting) via the existing ThemedMarkdownRenderable — the same renderer
the planning cards already use — instead of plain Text. The formatting
shows live as Navi streams. User messages stay plain text.

Navi Code TUI: sub-agent spawn card + nested styling for subagent thinking/planning ...

Sub-agent activity was either rendered as a generic tool card (spawn_agent) or
dropped to raw debug output (turn_thinking was unhandled in the TUI chat model
and the raw CLI). The webclient nests subagent events inside the spawn_agent
card; the TUI is flat, so nesting is conveyed with a distinct spawn card plus
left-indented, dimmed subagent cards.

New renderers/subagent.py:
- SpawnAgentStartedRenderer: "↘ subagent · <profile_id>" card showing the task
  (+ briefing dimmed), secondary border. Registered before ToolStartedRenderer.
- SpawnAgentResultRenderer: "↙ subagent · <profile_id> ✓/✗" card with the
  result, success/error border. Registered before ToolResultRenderer.

Nested subagent styling (left indent via Padding + dim):
- ThinkingRenderer: is_subagent → "subagent thinking" title, dim border, indented.
- PlanningStatusRenderer / PlanReadyRenderer: is_subagent → indented (label/title
  already mark it as subagent).
- ToolStartedRenderer / ToolResultRenderer: is_subagent → indented so inner
  tool calls read as nested inside the spawn card.

chat_model handles turn_thinking → thinking_block item with is_subagent meta;
chat_panel._refresh forwards is_subagent to the thinking renderer. Raw CLI
render.py prints turn_thinking as a [thinking] block (with "(subagent)" prefix).

Tests: spawn card shows profile/task and status; subagent thinking/planning/tool
cards are indented and labeled; non-subagent tool card is not indented;
turn_thinking creates a subagent thinking_block. 593 passed, 1 skipped.

Navi Code: render planning as a progress line + plan card, not raw events ...

planning_status and plan_ready events were unhandled in the TUI chat model and
the raw CLI renderer, so they fell through to raw debug output (TUI:
"plan_ready: {...}" status lines; raw CLI: "[event: plan_ready] {msg}").

TUI:
- New renderers/planning.py: PlanningStatusRenderer renders a "⚙ Planning ·
  <label>" line (info color; dim + "(subagent)" prefix for subagent planning);
  PlanReadyRenderer renders the plan as a Panel wrapping themed Markdown, titled
  "Plan" with an accent border ("subagent plan" + dim border for subagents).
- Registered both in default_registry().
- chat_model handles the events: non-subagent planning_status rolls in place
  (Analysis → Execution plan → Plan review share one line instead of stacking);
  plan_ready consumes the pending planning line and appends the plan card;
  subagent planning is appended as its own dim line/card so it does not bleed
  into the parent turn's indicator (matching the webclient).
- chat_panel._refresh maps the new kinds to the registry.

Raw CLI (render.py): planning_status prints "[planning] <label>"; plan_ready
prints a "[plan] … [/plan]" block with the plan text.

Tests: renderer accepts/render (label, subagent prefix, plan title/content);
chat_model rolling-in-place, plan_ready consumes indicator, subagent separation.
584 passed, 1 skipped.

Navi Code TUI: fix input box layout, command palette duplicate IDs, status renderer, and WS input loop ...

- clients/terminal/tui/widgets/input_box.py: switch Horizontal to Vertical with width: 100% for Input so it renders and accepts input in real terminals; add refresh on Input.Changed.
- clients/terminal/tui/screens/command_palette.py: remove fixed ListItem IDs to avoid DuplicateIds on fast filter.
- clients/terminal/tui/chat_model.py + renderers/status.py + widgets/chat_panel.py: render backend status events as dim system messages instead of raw dicts.
- clients/terminal/tui/ws_bridge.py: start NaviWebSocketClient.input_loop so enqueued user messages are actually sent to the backend.
- clients/terminal/tui/tui_app.py: focus InputBox synchronously in on_mount so typing works immediately.
- tests/clients/test_tui_app.py: regression test for visible input text.

Navi Code TUI: fix Phase 4 review critical/medium issues ...

- PermissionEngine: always-deny returns None via check(); is_always_deny() exposed for explicit rejection; default rules for code_exec/ssh_exec/shell; extract_target() made public.
- ShellRunner: set ShellResult.truncated when output is actually truncated.
- File refs: restrict paths to base_dir/home, block sensitive files/dirs, skip binary, support glob brackets, shared guess_language.
- Permission dialog: deny now renders synthetic tool_call before stopping; shell ! commands require permission with always-allow/deny persistence.
- Tests: add permission tests, fix file_refs/shell tests, add __init__.py to fix pytest name collisions, update websocket integration for AgentSessionOrchestrator.

504 passed, 1 skipped. Ruff clean.
