Architecture extensibility — event bus, middleware, auto-discovery, Pydantic profiles
...
- EventBus: async pub/sub for AgentEvents, WebSocket subscribes instead of direct yield
- Declarative serialization: AgentEvent.to_wire() on all event types
- Auto-discovery for LLM backends (_discover_backends) and workers (scan navi/workers/*.py)
- AgentProfile: Pydantic BaseModel with extra='allow', @field_validator for model coercion
- Tool middleware chain: pre/post execute hooks via ToolRegistry.add_middleware()
- LoggingMiddleware: built-in, logs every tool call
- Fix pg_trgm DDL: conditional GIN indexes via DO $$ block, no CREATE EXTENSION
- New files: event_bus.py, middleware.py, logging_middleware.py

Planning debug panel, todo auto-populate, scratchpad/persona improvements
...
- Planning debug panel: new Planning tab in debug/index.html shows raw
phase 1/2 outputs and token counts per planning run, stored in
session.planning_logs (new column in both SQLite and PostgreSQL)
- New GET /sessions/{id}/planning API endpoint
- PlanningDebugData internal event wires _run_planning() output into
session storage; never forwarded to WebSocket clients
- Phase 3 (plan critic) disabled — to be reworked with reflect integration
- Todo tool: auto-populated from plan steps after phase 2; model only
needs to call update/view, not set
- Scratchpad: clarified description and persona instructions; removed
context_transfer from user-facing docs (internal mechanism only)
- web_search: switched to ddgs package, SearXNG as primary backend,
DDG html-only fallback; added find_up action to filesystem tool
- Persona: added SCRATCHPAD and TODO sections with clear usage rules;
added NAVI.md project context instructions
- chat.js: fixed subagent planning event fallthrough into parent UI;
statusLabel cleared on first stream delta

Route subagent planning events into spawn_agent card in the UI
...
Previously PlanningStatus/PlanReady had no is_subagent flag, so subagent
planning spinners and plan cards rendered as top-level Navi planning UI.
Backend:
- Add is_subagent field to PlanningStatus and PlanReady events
- _run_planning accepts is_subagent param, passes it through all yields
- run_ephemeral calls _run_planning with is_subagent=True
- websocket.py forwards is_subagent in planning_status and plan_ready messages
Frontend (chat.js):
- onPlanningStatus: if is_subagent, set planningLabel on the last spawn_agent
card instead of msg.statusLabel
- onPlanReady: if is_subagent, push plan into spawn card steps and clear
planningLabel; otherwise behave as before
Frontend (ToolCard.vue):
- Render subagent-planning-indicator (spinner + label) when planningLabel set
- Render plan cards inside subagent steps using the same plan-card pattern
Also includes leftover session changes: spawn_agent default 40 in description
and manual, updated manual content.

Planning phases, context compression, and tool improvements
...
Agent:
- Planning now a 3-phase async generator: Analysis → Execution plan → AIHelper critic
- Yield PlanningStatus events before each phase (UI progress labels)
- Phase 1 runs with think=True for deeper analysis
- Phase 2 includes available tool list so executor assignments are accurate
- Phase 3: independent critic pass validates and corrects TOOL: names against real tool list
- Planning converted from list return to async generator (fixes token accounting)
Backend:
- Context compression threshold: 80% → 70% to trigger earlier
- Compressor summary prompt: structured sections (goal, work state, key facts, outputs, errors)
- Terminal output capped at 5000 chars to prevent context flooding
- Web search: region=wt-wt for DDG, country=ALL for Brave, language=all for SearxNG
- Scratchpad: mandate writing a 'goal' section at start of multi-step tasks
- secretary max_iterations: 40→25, temperature: 0.7→0.5
- server_admin max_iterations: 40→20
Webclient:
- ThinkingCard strips <thought> XML tags leaked by Ollama
- planning_status WS event wired to chat.onPlanningStatus()

Count AIHelper tokens in session metrics
...
Adds prompt/completion token fields to LLMResponse, populated by
OllamaBackend.complete(). AIHelper emits AIHelperTokensUsed into the
current event sink after each LLM call; run_stream drains it into
_subagent_tokens so AIHelper usage is reflected in the turn token delta.

Fix metrics: net token delta, subagent aggregation, ContextBar always visible
...
- run_stream: track _prev_tokens baseline before turn loop; compute net
token cost as (context_tokens - prev) + subagent_tokens for per-message cost
- run_stream: intercept SubagentComplete in sink drain loop to accumulate
subagent token and tool-call counts into the parent turn's totals
- run_ephemeral: already emitting SubagentComplete (from prior session)
- msg-meta-row: remove margin-left:auto from .msg-meta-time so time
groups inline with elapsed/tools/tokens instead of floating right
- ContextBar: remove v-if guard so bar is always visible (not only after
first LLM response with token data)

Add response metrics: elapsed time, tool calls, token count
...
Server:
- Message model: elapsed_seconds, tool_call_count, token_count fields
(display-only, excluded from LLM context via exclude_none)
- StreamEnd event: carries same three fields
- agent.run_stream: tracks turn start time, counts ToolEvent completions,
writes metrics onto the final assistant Message before saving to DB
- WebSocket: forwards metrics in stream_end payload
Client:
- chat.onStreamEnd: attaches elapsed_seconds, tool_call_count, token_count
to the streaming message on completion
- buildMessageList: scans each assistant group for metrics from history
- AssistantMessage: renders .msg-meta-row below the response —
timer icon + Xs · wrench icon + N tools · coins icon + Nk tokens · time
(each item only shown if present; time pushed right via margin-left: auto)

Expose compression summary as collapsible debug card in chat UI
...
ContextCompressed event now carries the full summary text produced by the
LLM. Compression notice in chat becomes a <details> element showing
message count (before→after) with the summary expandable on click.
Rendered as markdown via marked.js.

Add planning phase and scratchpad tool for smarter task execution
...
- ScratchpadTool: session-scoped working notepad with named sections
(write/append/read/clear). Lets Navi capture intermediate findings
between tool calls instead of losing track of them.
- Planning phase: when profile.planning_enabled=True, a fast pre-loop
LLM call (think=False, no tools) outlines a numbered plan before
any actions are taken. The plan is injected into session context as
an assistant message so the model naturally continues from it.
- PlanReady event + plan_ready WebSocket message + plan card in UI
(green-tinted, collapsible, mirroring thinking card design).
- secretary and server_admin profiles: planning_enabled=True,
scratchpad added to enabled_tools, system prompts updated with
explicit execution discipline instructions.

Add stop button and fix context compression hang
...
Stop generation:
- Client: send button toggles to red ■ during streaming; sends {type:stop} via WS
- Server: _stream_recv concurrently reads incoming messages during streaming using
asyncio.wait — stop signal is handled immediately without polling
- Cooperative stop via asyncio.Event (current_stop_event ContextVar): agent breaks
out of LLM async-for cleanly so aclose() fires → Ollama stream closes gracefully,
model stays in VRAM. No task.cancel() which would eject the model.
- StreamStopped event propagates through run_stream/run_ephemeral; sub-agents stop
via the same shared stop_event inherited through task context
Context compression fix:
- compress_context passes think=False to llm.complete() — no extended reasoning
during summarization which caused GPU hang
- Input truncated to 12k chars before sending to summarizer
- LLMBackend.complete() / OllamaBackend.complete() accept think: bool | None override

Major feature batch: visibility, planning, file uploads, streaming
...
- stream_complete(): streaming with tools for all LLM turns — thinking
now streams as ThinkingDelta/ThinkingEnd in real-time during tool-
selection turns, not just on the final response
- todo built-in tool: session-scoped plan manager (set/view/update/clear);
persona + all profiles updated with mandatory planning instructions
- TurnThinking event: sub-agent thinking forwarded to parent sink as a
collapsible block in the spawn_agent card
- File uploads: non-image files uploaded via XHR, shown as badges in
message bubble; SVG treated as regular file (not base64 image)
- session_files: POST /sessions/{id}/files, TTL cleanup, forbidden exts
- WebSocket reconnect: _AgentRun broadcast pattern, re-attach mid-stream
- UI: favicon, sidebar logo, turn-thinking cards, subagent thinking blocks,
token counter, draft persistence, file progress bar
- Removed AgentNote (content is always None alongside tool_calls)
- Ollama stream_complete: tool_calls captured from non-final chunk (done=False)

Live tool visibility: pending cards, sub-agent step log
...
Backend:
- ToolStarted event: emitted before tool execution begins so client
can render a pending card with spinner immediately
- ToolEvent gains is_subagent flag; ToolStarted same
- current_event_sink ContextVar in tools/base.py — run_stream() sets it
to an asyncio.Queue before create_task(); run_ephemeral() reads it and
puts ToolStarted/ToolEvent into the queue as each sub-agent step runs
- run_stream() tool loop: sequential execution via create_task() +
polling drain loop (20ms sleep); yields ToolStarted → sub-agent events
from sink → ToolEvent (completed) for each tool call
- run_ephemeral() rewritten to inline sequential tool execution with
sink emission (replaces _execute_tool_calls gather)
- _run_single_tool() helper extracted for run_stream()
- websocket.py handles tool_started and adds is_subagent to tool_call
Frontend:
- appendPendingToolCard(): creates card with spinner; spawn_agent opens
body immediately to show sub-agent log as it fills
- finalizeToolCard(): fills result, removes spinner, adds toggle; strips
"[Sub-agent result — ...]" reminder prefix from displayed text
- appendSubagentStep() / finalizeSubagentStep(): live step log inside
spawn_agent card — each sub-agent tool call gets a ↳ row
- app.js: tool_started → pending card; tool_call → finalize card;
is_subagent routing to sub-step vs main card; abandonStream() resets
pendingToolCard/pendingSubStep
- CSS: .spinner-inline for card headers; .subagent-log / .subagent-step
for nested step display; .tool-body-open for always-open spawn_agent
body; .tool-card.pending suppresses chevron

Review fixes: events module, circular imports, deps, vision-aware compression
...
- Extract all AgentEvent dataclasses to navi/core/events.py; import from
there in agent.py and __init__.py — eliminates circular import between
workers and core
- workers/compressor.py: remove runtime import hack, use navi.core.events
- workers/base.py: WorkerResult.events typed as list[AgentEvent] (was Any)
- api/deps.py: replace @lru_cache on mutable list with module-level
singletons (_registries, _workers)
- core/compressor.py: _format_for_summary returns (text, images); images
passed to summarization LLM so vision models describe them in summary;
non-vision models silently ignore the images field; docstring updated
- client/js/app.js: add comment explaining is_summary backward compat branch
