Set temperature=1.0, top_k=64, top_p=0.95 for all profiles (Google recommended for gemma4) ...

Also fixes discuss profile memory tools: use combined "memory" tool name, not nonexistent split variants.

Fix discuss profile planning: phase1 on (DIRECT gate), phase3 off ...

Model can skip planning via DIRECT; if it doesn't, analysis runs silently
without producing a plan card in the UI.

Add discuss profile; responsive WelcomeScreen for 6+ profiles ...

- New 'discuss' profile: creative Q&A and idea discussion, temp=1.0,
  planning phase 3 only, tools: web_search/view, scratchpad, reflect,
  memory, image_view, todo
- WelcomeScreen mobile: 2-column grid for profile cards, compact logo
  (row layout with subtitle on second line), reduced padding/gaps

Add per-phase planning flags and planning_mandatory ...

- planning_mandatory: disables DIRECT shortcut, forces all phases to run
- planning_phase1_enabled / phase2_enabled / phase3_enabled: per-phase toggles
- planning_phase2_enabled replaces planning_reflect_enabled (migrated in loader with backward compat)
- Migrate all profile configs; rewrite docs/profiles.md as full config reference

WelcomeScreen polish, root-path fix, docs update ...

- Move mobile sidebar button to top-left corner (no header bar backdrop)
- Show WelcomeScreen on / with no hash instead of auto-loading first session
- Docs: document Ollama multi-server fallback, model priority lists, OLLAMA_BACKENDS_FILE

Fix WelcomeScreen: add with-icon, mobile sidebar toggle ...

- Add with-icon class to Start button
- Add mobile-only header with sidebar toggle (reuses chat-header +
  btn-sidebar-toggle styles, hidden on desktop via existing CSS)
- Wire toggle-sidebar event through App.vue

Go to WelcomeScreen when active session is deleted ...

Previously deleting the active session would load the first session from
the list. Now it calls clearSession() which resets currentId to null,
and showWelcome now triggers on currentId === null (not just empty list).

Add Ollama multi-server fallback with in-memory blacklisting ...

- New FallbackOllamaBackend (navi/llm/fallback.py): tries servers and
  models in priority order; on LLMConnectionError blacklists the server
  for the process lifetime, on LLMModelNotFoundError blacklists the
  (server, model) pair — eliminates latency from repeated failed probes
- OllamaBackend now raises typed LLMConnectionError / LLMModelNotFoundError
  instead of bare LLMBackendError; accepts list[str] | str | None for model
- AgentProfile.model changed from str to list[str] (str auto-normalised);
  all profiles updated to ["gemma4:31b-cloud", "gemma4:26b-a4b-it-q4_K_M"]
- New config field OLLAMA_BACKENDS_FILE: path to [{host, api_key?}] JSON;
  when set, registry creates FallbackOllamaBackend instead of OllamaBackend
- ollama_backends.json template added (gitignored — contains API key)
- current_model ContextVar type widened to list[str] | str | None

Make server I/O non-blocking; update docs ...

- Wrap all heavy filesystem ops in asyncio.to_thread: filesystem tool
  (read/write/append/list/find/info/move/delete/query/smart_edit),
  image_view (read_bytes), share_file (shutil.copy2), write_tool
  (write_text, _register_user_tool), session_files (shutil.rmtree,
  iterdir), sessions upload endpoint (sync open/write → to_thread)
- Make delete_session_dir async; update its caller in sessions.py
- docs/config.md: fix wrong defaults (threshold 0.70, keep_recent 8),
  remove phantom SESSION_FILES_TTL_HOURS, add LLM timeouts, DATABASE_URL,
  PUBLIC_URL, Gmail, CONTEXT_SUMMARY_MAX_TOKENS sections
- docs/profiles.md: add missing tool_developer profile to table
- android-client: add WebView remote debugging; remove unused toolbar menu
- Remove stale helper scripts and test files

Add Android WebView client (android-client/) ...

Thin Android shell that loads the Navi web interface from a configured
server URL. All UI served from the server — no local assets, no rebuild
needed for interface updates.

Features:
- First-launch setup screen to enter server URL (stored in SharedPreferences)
- On connection error: clears saved URL so next launch re-asks
- Full-screen WebView, no toolbar
- Camera + gallery + file picker via WebChromeClient.onShowFileChooser
- HTTP cleartext enabled for local network access
- targetSdk 34 to avoid forced edge-to-edge on Android 15
- Adaptive icon: logo SVG converted to Android vector drawable

Agent improvements: mandatory planning, tool cleanup, smart_edit fixes ...

- Planning now mandatory on first message of every session (force_plan)
- RESOURCES, COMMITMENTS, ATOMICITY fields added to planning phase 1
- Todo auto-injected at iteration 0 so model tracks steps immediately
- Execution trigger injected after plan to prevent model treating plan as response
- Split developer profile: tool_developer (Navi tools) vs developer (general code)
- Simplified persona.txt: trimmed redundant content now handled by mechanics
- AIHelper.ask(): 120s timeout via asyncio.wait_for to prevent smart_edit hangs
- filesystem._smart_edit(): atomic write via temp file + os.replace()
- Removed 5 junk user tools (game project artifacts, trivial utilities)
- Removed instagram tools (to be rewritten); cleaned enabled.json

Restructure persona: concrete information gathering protocol ...

- Replace abstract CONTEXT FIRST principle with explicit numbered protocol
  (check summary → memory_search → NAVI.md → ask user)
- Move protocol to top of persona (after identity) so it has maximum weight
- NAVI.md section: remove READ instructions (now in protocol), keep only WRITE
- LONG-TERM MEMORY: remove "search proactively" line (now in protocol),
  keep only save/forget instructions
- memory_search description: remove misleading "call at start of each session"
  (summary is already auto-injected); clarify when to actually call it

Improve memory search: normalize query, AND-first, relevance scoring ...

- _normalize_query(): hyphens/underscores/slashes/dots → word boundaries,
  strip all other punctuation, lowercase — fixes comma-separated keyword bug
- Auto-dump: if ≤ 60 facts in DB, skip search and return all (no false negatives
  in a small personal memory store)
- AND-first: try matching all terms; fall back to OR only when AND returns nothing
- OR-fallback with scoring: facts matching more terms rank higher (score DESC),
  ties broken by recency

- sessions.md: add name, planning_logs fields; message flags (is_plan, is_compression,
  is_summary, thinking); set_name store op; debug endpoints section
- api.md: full rewrite — add generate-name, planning, file download endpoints;
  all missing WS events; correct message field table with is_plan/is_compression
- tools.md: update user tools list with all current tools

Add NAVI.md navigation hub and update core docs ...

NAVI.md: lightweight project entry point for Navi — server command,
key paths, doc map with query instructions, tool manual index.
All profiles read this; detailed content stays in docs/.

docs/agent.md: rewrite to cover 3-phase planning, all 10 thinking
mechanics flags, adaptive replan, anti-stall, goal anchoring.

docs/profiles.md: update AgentProfile fields (all flags), correct
profile list (secretary/server_admin/developer), JSON config format,
auto-discovery instead of manual registration.

Remove code-specific scoping rules from planning prompt ...

Keep only the universal comma test heuristic — code-specific rules
were too narrow and cluttered the prompt.

Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>

Tighten AGENT step scoping in planning prompt ...

Added comma test heuristic: if a step description lists things with
'and' or commas, each item is a separate step. Added code-specific
guidance: one step = one file or one focused feature addition, never
scaffold + logic + helpers combined. Replaced abstract good/bad
examples with concrete code implementation examples.

Fix session switch race: connect WS after REST fetch completes ...

loadSession was setting currentId before the REST fetch, which triggered
ws.connect() immediately. If WS replay arrived before the REST response,
onStreamStart() would push a streaming message, then the REST response
would overwrite messages.value entirely — leaving streamingMsg pointing
to an orphaned object no longer in the array.

Fix: move currentId and location.hash assignment to after the REST fetch
so the WS connection is established only once messages are populated.

WebSocket event replay buffer for disconnect resilience ...

On reconnect to an active agent run the server now replays all events
emitted since the turn started, then switches to live forwarding.
This eliminates the gap where tool cards, thinking blocks and stream
deltas were permanently lost after a network blip.

Server (_AgentRun):
- events: list[dict] buffers every serialised agent event
- broadcast() serialises and appends before putting in subscriber queues
- reconnect flow: subscribe → replay_count snapshot → stream_start →
  replay events[0:replay_count] → live _stream_to_client

Client:
- onStreamStart() removes the frozen ghost message instead of marking
  done=true, so replay cleanly rebuilds the message from scratch
- replayMode flag suppresses animations during replay
- onReplayStart/onReplayEnd handlers set/clear the flag and restore
  animate on the message once live events resume

Add CONTEXT FIRST principle to persona ...

Navi should proactively gather context before asking the user for
anything — credentials, preferences, environment. Strengthens the
LONG-TERM MEMORY instruction from reactive ("when referenced") to
proactive ("before asking").

Adaptive re-plan on todo step failure ...

When a todo step is newly marked failed, queue a targeted system message
for the next iteration prompting the model to revise its remaining pending
steps before continuing. Enabled by adaptive_replan_enabled flag (on by
default in developer profile). Zero overhead when no failure occurs.

Autonomous reasoning improvements: budget, anchoring, anti-stall, validation ...

- AgentProfile: per-profile thinking mechanics flags (think_enabled,
  iteration_budget_enabled, goal_anchoring, anti_stall, step_validation,
  planning_reflect, adaptive_replan) — all profiles updated in config.json
- Iteration budget: inject remaining iterations into context so model knows
  when to wrap up; urgency levels at ≤7 and ≤3 remaining
- Goal anchoring: inject original goal + todo state every N iterations to
  prevent drift on long tasks
- Anti-stall: two signals — no todo progress for N iterations, or identical
  tool calls repeated N times; warning injected into context
- Todo step validation: marking done requires a validation field describing
  how result was verified; failed gets a soft nudge with tip for re-planning
- stream_complete: add think param to base class, ollama and openai backends
- Summarizer: raise max_tokens 1024→3000, expand system prompt with
  user-preferences section and verbatim-value instructions
- Compression card: persist to session.messages (is_compression flag on
  Message), show expandable summary in webclient with markdown body
- ToolResult.to_message_content: always include output on failure so
  tracebacks and error details reach the model (fixes silent Error: None)
- Developer profile: fix subagent profile secretary→developer, add write_tool
  to subagent_tools, clarify write_tool vs filesystem in system prompt
