feat: Session Sovereignty Report Generator (#957 )

- Add src/timmy/sovereignty/session_report.py with generate_report(), commit_report(), generate_and_commit_report(), and mark_session_start() - Add session report imports to src/timmy/sovereignty/__init__.py - Wire session start/end hooks into dashboard lifespan - Add 23 unit tests in tests/timmy/test_session_report.py Fixes #957 Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
[claude] refactor: break up monolithic tools.py into a tools/ package (#1215 ) (#1221 )

+# Nexus — Scope & Acceptance Criteria
+
+**Issue:** #1208
+**Date:** 2026-03-23
+**Status:** Initial implementation complete; teaching/RL harness deferred
+
+---
+
+## Summary
+
+The **Nexus** is a persistent conversational space where Timmy lives with full
+access to his live memory. Unlike the main dashboard chat (which uses tools and
+has a transient feel), the Nexus is:
+
+- **Conversational only** — no tool approval flow; pure dialogue
+- **Memory-aware** — semantically relevant memories surface alongside each exchange
+- **Teachable** — the operator can inject facts directly into Timmy's live memory
+- **Persistent** — the session survives page refreshes; history accumulates over time
+- **Local** — always backed by Ollama; no cloud inference required
+
+This is the foundation for future LoRA fine-tuning, RL training harnesses, and
+eventually real-time self-improvement loops.
+
+---
+
+## Scope (v1 — this PR)
+
+| Area | Included | Deferred |
+|------|----------|----------|
+| Conversational UI | ✅ Chat panel with HTMX streaming | Streaming tokens |
+| Live memory sidebar | ✅ Semantic search on each turn | Auto-refresh on teach |
+| Teaching panel | ✅ Inject personal facts | Bulk import, LoRA trigger |
+| Session isolation | ✅ Dedicated `nexus` session ID | Per-operator sessions |
+| Nav integration | ✅ NEXUS link in INTEL dropdown | Mobile nav |
+| CSS/styling | ✅ Two-column responsive layout | Dark/light theme toggle |
+| Tests | ✅ 9 unit tests, all green | E2E with real Ollama |
+| LoRA / RL harness | ❌ deferred to future issue | |
+| Auto-falsework | ❌ deferred | |
+| Bannerlord interface | ❌ separate track | |
+
+---
+
+## Acceptance Criteria
+
+### AC-1: Nexus page loads
+- **Given** the dashboard is running
+- **When** I navigate to `/nexus`
+- **Then** I see a two-panel layout: conversation on the left, memory sidebar on the right
+- **And** the page title reads "// NEXUS"
+- **And** the page is accessible from the nav (INTEL → NEXUS)
+
+### AC-2: Conversation-only chat
+- **Given** I am on the Nexus page
+- **When** I type a message and submit
+- **Then** Timmy responds using the `nexus` session (isolated from dashboard history)
+- **And** no tool-approval cards appear — responses are pure text
+- **And** my message and Timmy's reply are appended to the chat log
+
+### AC-3: Memory context surfaces automatically
+- **Given** I send a message
+- **When** the response arrives
+- **Then** the "LIVE MEMORY CONTEXT" panel shows up to 4 semantically relevant memories
+- **And** each memory entry shows its type and content
+
+### AC-4: Teaching panel stores facts
+- **Given** I type a fact into the "TEACH TIMMY" input and submit
+- **When** the request completes
+- **Then** I see a green confirmation "✓ Taught: <fact>"
+- **And** the fact appears in the "KNOWN FACTS" list
+- **And** the fact is stored in Timmy's live memory (`store_personal_fact`)
+
+### AC-5: Empty / invalid input is rejected gracefully
+- **Given** I submit a blank message or fact
+- **Then** no request is made and the log is unchanged
+- **Given** I submit a message over 10 000 characters
+- **Then** an inline error is shown without crashing the server
+
+### AC-6: Conversation can be cleared
+- **Given** the Nexus has conversation history
+- **When** I click CLEAR and confirm
+- **Then** the chat log shows only a "cleared" confirmation
+- **And** the Agno session for `nexus` is reset
+
+### AC-7: Graceful degradation when Ollama is down
+- **Given** Ollama is unavailable
+- **When** I send a message
+- **Then** an error message is shown inline (not a 500 page)
+- **And** the app continues to function
+
+### AC-8: No regression on existing tests
+- **Given** the nexus route is registered
+- **When** `tox -e unit` runs
+- **Then** all 343+ existing tests remain green
+
+---
+
+## Future Work (separate issues)
+
+1. **LoRA trigger** — button in the teaching panel to queue a fine-tuning run
+   using the current Nexus conversation as training data
+2. **RL harness** — reward signal collection during conversation for RLHF
+3. **Auto-falsework pipeline** — scaffold harness generation from conversation
+4. **Bannerlord interface** — Nexus as the live-memory bridge for in-game Timmy
+5. **Streaming responses** — token-by-token display via WebSocket
+6. **Per-operator sessions** — isolate Nexus history by logged-in user
