+# Browser Contract — The Nexus

+## 3. Three.js Contract
+
+After initialization completes:
+
+- `window` has a THREE renderer created from `#nexus-canvas`
+- The canvas has a WebGL rendering context
+- `scene` is a `THREE.Scene` with fog
+- `camera` is a `THREE.PerspectiveCamera`

+2. Progress bar fills to 100%
+3. Loading screen fades out
+4. Enter prompt appears
+5. User clicks → enter prompt fades → HUD appears
+
+## 5. Provenance Contract
+
+A validation run MUST prove:

+- The served files match a known hash manifest from `Timmy_Foundation/the-nexus` main
+- No file is served from `/Users/apayne/the-matrix` or other stale source
+- The hash manifest is generated from a clean git checkout
+- Screenshot evidence is captured and timestamped
+
+## 6. Data Contract
+
+- `portals.json` MUST parse as valid JSON array
+- Each portal MUST have: `id`, `name`, `status`, `destination`
+- `vision.json` MUST parse as valid JSON
+- `manifest.json` MUST have `name`, `start_url`, `theme_color`
+
+## 7. WebSocket Contract
+
+- `server.py` starts without error on port 8765
+- A browser client can connect to `ws://localhost:8765`
+- The connection status indicator reflects connected state

+# FINDINGS: MemPalace Local AI Memory System Assessment & Leverage Plan
+
+**Issue:** #1047
+**Date:** 2026-04-10
+**Investigator:** mimo-v2-pro (swarm researcher)
+
+---
+
+## 1. What Issue #1047 Claims
+
+The issue (authored by Bezalel, dated 2026-04-07) describes MemPalace as:
+- An open-source local-first AI memory system with highest published LongMemEval scores (96.6% R@5)
+- A Python CLI + MCP server using ChromaDB + SQLite with a "palace" hierarchy metaphor
+- AAAK compression dialect for ~30x context compression
+- 19 MCP tools for agent memory
+
+It recommends that every wizard clone/vendor MemPalace, configure rooms, mine workspace, and wire the searcher into heartbeats.
+
+## 2. What Actually Exists in the Codebase (Current State)
+
+The Nexus repo already contains **substantial MemPalace integration** that goes well beyond the original research proposal. Here is the full inventory:
+
+### 2.1 Core Python Layer — `nexus/mempalace/` (3 files, ~290 lines)
+
+| File | Purpose |
+|------|---------|
+| `config.py` | Environment-driven config: palace paths, fleet path, wing name, core rooms, collection name |
+| `searcher.py` | ChromaDB-backed search/write API with `search_memories()`, `search_fleet()`, `add_memory()` |
+| `__init__.py` | Package marker |
+
+**Status:** Functional. Clean API. Lazy ChromaDB import with graceful `MemPalaceUnavailable` exception.
+
+### 2.2 Fleet Management Tools — `mempalace/` (8 files, ~800 lines)
+
+| File | Purpose |
+|------|---------|
+| `rooms.yaml` | Fleet-wide room taxonomy standard (5 core rooms + optional rooms) |
+| `validate_rooms.py` | Validates wizard `mempalace.yaml` against fleet standard |
+| `audit_privacy.py` | Scans fleet palace for policy violations (raw drawers, oversized closets, private paths) |
+| `retain_closets.py` | 90-day retention enforcement for closet aging |
+| `export_closets.sh` | Privacy-safe closet export for rsync to Alpha fleet palace |
+| `fleet_api.py` | HTTP API for shared fleet palace (search, record, wings) |
+| `tunnel_sync.py` | Pull closets from remote wizard's fleet API into local palace |
+| `__init__.py` | Package marker |
+
+**Status:** Well-structured. Each tool has clear CLI interface and proper error handling.
+
+### 2.3 Evennia MUD Integration — `nexus/evennia_mempalace/` (6 files, ~580 lines)
+
+| File | Purpose |
+|------|---------|
+| `commands/recall.py` | `CmdRecall` (semantic search), `CmdEnterRoom` (teleport), `CmdAsk` (NPC query) |
+| `commands/write.py` | `CmdRecord`, `CmdNote`, `CmdEvent` (memory writing commands) |
+| `typeclasses/rooms.py` | `MemPalaceRoom` typeclass |
+| `typeclasses/npcs.py` | `StewardNPC` with question-answering via palace search |
+
+**Status:** Complete. Evennia stub fallback for testing outside live environment.
+
+### 2.4 3D Visualization — `nexus/components/spatial-memory.js` (~665 lines)
+
+Maps memory categories to spatial regions in the Nexus Three.js world:
+- Inner ring: Documents, Projects, Code, Conversations, Working Memory, Archive
+- Outer ring (MemPalace zones, issue #1168): User Preferences, Project Facts, Tool Knowledge, General Facts
+- Crystal geometry with deterministic positioning, connection lines, localStorage persistence
+
+**Status:** Functional 3D visualization with region markers, memory crystals, and animation.
+
+### 2.5 Frontend Integration — `mempalace.js` (~44 lines)
+
+Basic Electron/browser integration class that:
+- Initializes a palace wing
+- Auto-mines chat content every 30 seconds
+- Exposes `search()` method
+- Updates stats display
+
+**Status:** Minimal but functional as a bridge between browser UI and CLI mempalace.
+
+### 2.6 Scripts & Automation — `scripts/` (5 files)
+
+| File | Purpose |
+|------|---------|
+| `mempalace-incremental-mine.sh` | Re-mines only changed files since last run |
+| `mempalace_nightly.sh` | Nightly maintenance |
+| `mempalace_export.py` | Export utility |
+| `validate_mempalace_taxonomy.py` | Taxonomy validation script |
+| `audit_mempalace_privacy.py` | Privacy audit script |
+| `sync_fleet_to_alpha.sh` | Fleet sync to Alpha server |
+
+### 2.7 Tests — `tests/` (7 test files)
+
+| File | Tests |
+|------|-------|
+| `test_mempalace_searcher.py` | Searcher API, config |
+| `test_mempalace_validate_rooms.py` | Room taxonomy validation |
+| `test_mempalace_retain_closets.py` | Closet retention |
+| `test_mempalace_audit_privacy.py` | Privacy auditor |
+| `test_mempalace_fleet_api.py` | Fleet HTTP API |
+| `test_mempalace_tunnel_sync.py` | Remote wizard sync |
+| `test_evennia_mempalace_commands.py` | Evennia commands + NPC helpers |
+
+### 2.8 CI/CD
+
+- **ci.yml**: Validates palace taxonomy on every PR, plus Python/JSON/YAML syntax checks
+- **weekly-audit.yml**: Monday 05:00 UTC — runs privacy audit + dry-run retention against test fixtures
+
+### 2.9 Documentation
+
+- `docs/mempalace_taxonomy.yaml` — Full taxonomy standard (145 lines)
+- `docs/mempalace/rooms.yaml` — Rooms documentation
+- `docs/mempalace/bezalel_example.yaml` — Example wizard config
+- `docs/bezalel/evennia/` — Evennia integration examples (steward NPC, palace commands)
+- `reports/bezalel/2026-04-07-mempalace-field-report.md` — Original field report
+
+## 3. Gap Analysis: Issue #1047 vs. Reality
+
+| Issue #1047 Proposes | Current State | Gap |
+|---------------------|---------------|-----|
+| "Each wizard should clone/vendor it" | Vendor infrastructure exists (`scripts/mempalace-incremental-mine.sh`) | **DONE** |
+| "Write a mempalace.yaml" | Fleet taxonomy standard + validator exist | **DONE** |
+| "Run mempalace mine" | Incremental mining script exists | **DONE** |
+| "Wire searcher into heartbeat scripts" | `nexus/mempalace/searcher.py` provides API | **DONE** (needs adoption verification) |
+| AAAK compression | Not implemented in repo | **OPEN** — no AAAK dialect code |
+| MCP server (19 tools) | No MCP server integration | **OPEN** — no MCP tool definitions |
+| Benchmark validation | No LongMemEval test harness in repo | **OPEN** — claims unverified locally |
+| Fleet-wide adoption | Only Bezalel field report exists | **OPEN** — no evidence of Timmy/Allegro/Ezra adoption |
+| Hermes harness integration | No direct harness/memory-tool bridge | **OPEN** — searcher exists but no harness wiring |
+
+## 4. What's Actually Broken
+
+### 4.1 No AAAK Implementation
+The issue describes AAAK (~30x compression, ~170 tokens wake-up context) as a key feature, but there is zero AAAK code in the repo. The `nexus/mempalace/` layer has no compression functions. This is a missing feature, not a bug.
+
+### 4.2 No MCP Server Bridge
+The upstream MemPalace offers 19 MCP tools, but the Nexus integration only exposes the ChromaDB Python API. There is no MCP server definition, no tool registration for the harness, and no bridge to the `mcp_config.json` at repo root.
+
+### 4.3 Fleet Adoption Gap
+Only Bezalel has a documented field report (#1072). There is no evidence that Timmy, Allegro, or Ezra have populated palaces, configured room taxonomies, or run incremental mining. The `export_closets.sh` script hardcodes Bezalel paths.
+
+### 4.4 Frontend Integration Stale
+`mempalace.js` references `window.electronAPI.execPython()` which only works in the Electron shell. The main `app.js` (Three.js world) does not import or use `mempalace.js`. The `spatial-memory.js` component defines MemPalace zones but has no data pipeline to populate them from actual palace data.
+
+### 4.5 Upstream Quality Concern
+Bezalel's field report notes the upstream repo is "astroturfed hype" — 13.4k LOC in a single commit, 5,769 GitHub stars in 48 hours, ~125 lines of tests. The code is not malicious but is not production-grade. The Nexus has effectively forked/vendored the useful parts and rewritten the critical integration layers.
+
+## 5. What's Working Well
+
+1. **Clean architecture separation** — `nexus/mempalace/` is a proper Python package with config/searcher separation. Testable without ChromaDB installed.
+
+2. **Privacy-first fleet design** — closet-only export policy, privacy auditor, retention enforcement, and private path detection are solid operational safeguards.
+
+3. **Taxonomy standardization** — `rooms.yaml` + validator ensures consistent memory structure across wizards.
+
+4. **CI integration** — Taxonomy validation in PR checks + weekly privacy audit cron are good DevOps practices.
+
+5. **Evennia integration** — The MUD commands (recall, enter room, ask steward) are well-designed and testable outside Evennia via stubs.
+
+6. **Spatial visualization** — `spatial-memory.js` is a creative 3D representation with deterministic positioning and category zones.
+
+## 6. Recommended Actions
+
+### Priority 1: Fleet Adoption Verification (effort: small)
+- Confirm each wizard (Timmy, Allegro, Ezra) has run `mempalace mine` and has a populated palace
+- Verify `mempalace.yaml` exists on each wizard's VPS
+- Update `export_closets.sh` to not hardcode Bezalel paths (use env vars)
+
+### Priority 2: Hermes Harness Bridge (effort: medium)
+- Wire `nexus/mempalace/searcher.py` into the Hermes harness as a memory tool
+- Add memory search/recall to the agent loop so wizards get cross-session context automatically
+- Map MemPalace search to the existing `memory`/`fact_store` tools or add a dedicated `palace_search` tool
+
+### Priority 3: MCP Server Registration (effort: medium)
+- Create an MCP server that exposes search, write, and status tools
+- Register in `mcp_config.json`
+- Enable any harness agent to use MemPalace without Python imports
+
+### Priority 4: AAAK Compression (effort: large, optional)
+- Implement or port the AAAK compression dialect
+- Generate wake-up context summaries from palace data
+- This is a nice-to-have, not critical — the raw ChromaDB search is functional
+
+### Priority 5: 3D Pipeline Bridge (effort: medium)
+- Connect `spatial-memory.js` to live palace data via WebSocket or REST
+- Populate memory crystals from actual search results
+- Visual feedback when new memories are added
+
+## 7. Effort Summary
+
+| Action | Effort | Impact |
+|--------|--------|--------|
+| Fleet adoption verification | 2-4 hours | High — ensures all wizards have memory |
+| Hermes harness bridge | 1-2 days | High — automatic cross-session context |
+| MCP server registration | 1 day | Medium — enables any agent to use palace |
+| AAAK compression | 2-3 days | Low — nice-to-have |
+| 3D pipeline bridge | 1-2 days | Medium — visual representation of memory |
+| Fix export_closets.sh hardcoded paths | 30 min | Low — operational hygiene |
+
+## 8. Conclusion
+
+Issue #1047 was a research request from 2026-04-07. Since then, significant implementation work has been completed — far exceeding the original proposal. The core memory infrastructure (searcher, fleet tools, privacy, taxonomy, Evennia integration, tests, CI) is **built and functional**.
+
+The primary remaining gap is **fleet-wide adoption** (only Bezalel has documented use) and **harness integration** (the searcher exists but isn't wired into the agent loop). The AAAK and MCP features from the original research are not implemented but are not blocking — the ChromaDB-backed search provides the core value proposition.
+
+**Verdict:** The MemPalace integration is substantially complete at the infrastructure level. The next bottleneck is operational adoption and harness wiring, not new feature development.

+# Security Audit: NostrIdentity BIP340 Schnorr Signatures — Timing Side-Channel Analysis
+
+**Issue:** #801
+**Repository:** Timmy_Foundation/the-nexus
+**File:** `nexus/nostr_identity.py`
+**Auditor:** mimo-v2-pro swarm worker
+**Date:** 2026-04-10
+
+---
+
+## Summary
+
+The pure-Python BIP340 Schnorr signature implementation in `NostrIdentity` has **multiple timing side-channel vulnerabilities** that could allow an attacker with precise timing measurements to recover the private key. The implementation is suitable for prototyping and non-adversarial environments but **must not be used in production** without the fixes described below.
+
+---
+
+## Architecture
+
+The Nostr sovereign identity system consists of two files:
+
+- **`nexus/nostr_identity.py`** — Pure-Python secp256k1 + BIP340 Schnorr signature implementation. No external dependencies. Contains `NostrIdentity` class for key generation, event signing, and pubkey derivation.
+- **`nexus/nostr_publisher.py`** — Async WebSocket publisher that sends signed Nostr events to public relays (damus.io, nos.lol, snort.social).
+- **`app.js` (line 507)** — Browser-side `NostrAgent` class uses **mock signatures** (`mock_id`, `mock_sig`), not real crypto. Not affected.
+
+---
+
+## Vulnerabilities Found
+
+### 1. Branch-Dependent Scalar Multiplication — CRITICAL
+
+**Location:** `nostr_identity.py:41-47` — `point_mul()`
+
+```python
+def point_mul(p, n):
+    r = None
+    for i in range(256):
+        if (n >> i) & 1:        # <-- branch leaks Hamming weight
+            r = point_add(r, p)
+        p = point_add(p, p)
+    return r
+```
+
+**Problem:** The `if (n >> i) & 1` branch causes `point_add(r, p)` to execute only when the bit is 1. An attacker measuring signature generation time can determine which bits of the scalar are set, recovering the private key from a small number of timed signatures.
+
+**Severity:** CRITICAL — direct private key recovery.
+
+**Fix:** Use a constant-time double-and-always-add algorithm:
+
+```python
+def point_mul(p, n):
+    r = (None, None)
+    for i in range(256):
+        bit = (n >> i) & 1
+        r0 = point_add(r, p)         # always compute both
+        r = r0 if bit else r          # constant-time select
+        p = point_add(p, p)
+    return r
+```
+
+Or better: use Montgomery ladder which avoids point doubling on the identity.
+
+---
+
+### 2. Branch-Dependent Point Addition — CRITICAL
+
+**Location:** `nostr_identity.py:28-39` — `point_add()`
+
+```python
+def point_add(p1, p2):
+    if p1 is None: return p2       # <-- branch leaks operand state
+    if p2 is None: return p1       # <-- branch leaks operand state
+    (x1, y1), (x2, y2) = p1, p2
+    if x1 == x2 and y1 != y2: return None  # <-- branch leaks equality
+    if x1 == x2:                          # <-- branch leaks equality
+        m = (3 * x1 * x1 * inverse(2 * y1, P)) % P
+    else:
+        m = ((y2 - y1) * inverse(x2 - x1, P)) % P
+    ...
+```
+
+**Problem:** Multiple conditional branches leak whether inputs are the identity point, whether x-coordinates are equal, and whether y-coordinates are negations. Combined with the scalar multiplication above, this gives an attacker detailed timing information about intermediate computations.
+
+**Severity:** CRITICAL — compounds the scalar multiplication leak.
+
+**Fix:** Replace with a branchless point addition using Jacobian or projective coordinates with dummy operations:
+
+```python
+def point_add(p1, p2):
+    # Use Jacobian coordinates; always perform full addition
+    # Use conditional moves (simulated with arithmetic masking)
+    # for selecting between doubling and addition paths
+```
+
+---
+
+### 3. Branch-Dependent Y-Parity Check in Signing — HIGH
+
+**Location:** `nostr_identity.py:57-58` — `sign_schnorr()`
+
+```python
+R = point_mul(G, k)
+if R[1] % 2 != 0:       # <-- branch leaks parity of R's y-coordinate
+    k = N - k
+```
+
+**Problem:** The conditional negation of `k` based on the y-parity of R leaks information about the nonce through timing. While less critical than the point_mul leak (it's a single bit), combined with other leaks it aids key recovery.
+
+**Severity:** HIGH
+
+**Fix:** Use arithmetic masking:
+
+```python
+R = point_mul(G, k)
+parity = R[1] & 1
+k = (k * (1 - parity) + (N - k) * parity) % N  # constant-time select
+```
+
+---
+
+### 4. Non-Constant-Time Modular Inverse — MEDIUM
+
+**Location:** `nostr_identity.py:25-26` — `inverse()`
+
+```python
+def inverse(a, n):
+    return pow(a, n - 2, n)
+```
+
+**Problem:** CPython's built-in `pow()` with 3 args uses Montgomery ladder internally, which is *generally* constant-time for fixed-size operands. However:
+- This is an implementation detail, not a guarantee.
+- PyPy, GraalPy, and other Python runtimes may use different algorithms.
+- The exponent `n-2` has a fixed Hamming weight for secp256k1's `N`, so this specific case is less exploitable, but relying on it is fragile.
+
+**Severity:** MEDIUM — implementation-dependent; low risk on CPython specifically.
+
+**Fix:** Implement Fermat's little theorem inversion with blinding, or use a dedicated constant-time GCD algorithm (extended binary GCD).
+
+---
+
+### 5. Non-RFC6979 Nonce Generation — LOW (but non-standard)
+
+**Location:** `nostr_identity.py:55`
+
+```python
+k = int.from_bytes(sha256(privkey.to_bytes(32, 'big') + msg_hash), 'big') % N
+```
+
+**Problem:** The nonce derivation is `SHA256(privkey || msg_hash)` which is deterministic but doesn't follow RFC6979 (HMAC-based DRBG). Issues:
+- Not vulnerable to timing (it's a single hash), but could be vulnerable to related-message attacks if the same key signs messages with predictable relationships.
+- BIP340 specifies `tagged_hash("BIP0340/nonce", ...)` with specific domain separation, which is not used here.
+
+**Severity:** LOW — not a timing issue but a cryptographic correctness concern.
+
+**Fix:** Follow RFC6979 or BIP340's tagged hash approach:
+
+```python
+def sign_schnorr(msg_hash, privkey):
+    # BIP340 nonce generation with tagged hash
+    t = privkey.to_bytes(32, 'big')
+    if R_y_is_odd:
+        t = bytes(b ^ 0x01 for b in t)  # negate if needed
+    k = int.from_bytes(tagged_hash("BIP0340/nonce", t + pubkey + msg_hash), 'big') % N
+```
+
+---
+
+### 6. Private Key Bias in Random Generation — LOW
+
+**Location:** `nostr_identity.py:69`
+
+```python
+self.privkey = int.from_bytes(os.urandom(32), 'big') % N
+```
+
+**Problem:** `os.urandom(32)` produces values in `[0, 2^256)`, while `N` is slightly less than `2^256`. The modulo reduction introduces a negligible bias (~2^-128). Not exploitable in practice, but not the cleanest approach.
+
+**Severity:** LOW — theoretically biased, practically unexploitable.
+
+**Fix:** Use rejection sampling or derive from a hash:
+
+```python
+def generate_privkey():
+    while True:
+        candidate = int.from_bytes(os.urandom(32), 'big')
+        if 0 < candidate < N:
+            return candidate
+```
+
+---
+
+### 7. No Scalar/Point Blinding — MEDIUM
+
+**Location:** Global — no blinding anywhere in the implementation.
+
+**Problem:** The implementation has no countermeasures against:
+- **Power analysis** (DPA/SPA) on embedded systems
+- **Cache-timing attacks** on shared hardware (VMs, cloud)
+- **Electromagnetic emanation** attacks
+
+Adding random blinding to scalar multiplication (multiply by `r * r^-1` where `r` is random) would significantly raise the bar for side-channel attacks beyond simple timing.
+
+**Severity:** MEDIUM — not timing-specific, but important for hardening.
+
+---
+
+## What's NOT Vulnerable (Good News)
+
+1. **The JS-side `NostrAgent` in `app.js`** uses mock signatures (`mock_id`, `mock_sig`) — not real crypto, not affected.
+2. **`nostr_publisher.py`** correctly imports and uses `NostrIdentity` without modifying its internals.
+3. **The hash functions** (`sha256`, `hmac_sha256`) use Python's `hashlib` which delegates to OpenSSL — these are constant-time.
+4. **The JSON serialization** in `sign_event()` is deterministic and doesn't leak timing.
+
+---
+
+## Recommended Fix (Full Remediation)
+
+### Priority 1: Replace with secp256k1-py or coincurve (IMMEDIATE)
+
+The fastest, most reliable fix is to stop using the pure-Python implementation entirely:
+
+```python
+# nostr_identity.py — replacement using coincurve
+import coincurve
+import hashlib
+import json
+import os
+
+class NostrIdentity:
+    def __init__(self, privkey_hex=None):
+        if privkey_hex:
+            self.privkey = bytes.fromhex(privkey_hex)
+        else:
+            self.privkey = os.urandom(32)
+        self.pubkey = coincurve.PrivateKey(self.privkey).public_key.format(compressed=True)[1:].hex()
+
+    def sign_event(self, event):
+        event_data = [0, event['pubkey'], event['created_at'], event['kind'], event['tags'], event['content']]
+        serialized = json.dumps(event_data, separators=(',', ':'))
+        msg_hash = hashlib.sha256(serialized.encode()).digest()
+        event['id'] = msg_hash.hex()
+        # Use libsecp256k1's BIP340 Schnorr (constant-time C implementation)
+        event['sig'] = coincurve.PrivateKey(self.privkey).sign_schnorr(msg_hash).hex()
+        return event
+```
+
+**Effort:** ~2 hours (swap implementation, add `coincurve` to `requirements.txt`, test)
+**Risk:** Adds a C dependency. If pure-Python is required (sovereignty constraint), use Priority 2.
+
+### Priority 2: Pure-Python Constant-Time Rewrite (IF PURE PYTHON REQUIRED)
+
+If the sovereignty constraint (no C dependencies) must be maintained, rewrite the elliptic curve operations:
+
+1. **Replace `point_mul`** with Montgomery ladder (constant-time by design)
+2. **Replace `point_add`** with Jacobian coordinate addition that always performs both doubling and addition, selecting with arithmetic masking
+3. **Replace `inverse`** with extended binary GCD with blinding
+4. **Fix nonce generation** to follow RFC6979 or BIP340 tagged hashes
+5. **Fix key generation** to use rejection sampling
+
+**Effort:** ~8-12 hours (careful implementation + test vectors from BIP340 spec)
+**Risk:** Pure-Python crypto is inherently slower (~100ms per signature vs ~1ms with libsecp256k1)
+
+### Priority 3: Hybrid Approach
+
+Use `coincurve` when available, fall back to pure-Python with warnings:
+
+```python
+try:
+    import coincurve
+    USE_LIB = True
+except ImportError:
+    USE_LIB = False
+    import warnings
+    warnings.warn("Using pure-Python Schnorr — vulnerable to timing attacks. Install coincurve for production use.")
+```
+
+**Effort:** ~3 hours
+
+---
+
+## Effort Estimate
+
+| Fix | Effort | Risk Reduction | Recommended |
+|-----|--------|----------------|-------------|
+| Replace with coincurve (Priority 1) | 2h | Eliminates all timing issues | YES — do this |
+| Pure-Python constant-time rewrite (Priority 2) | 8-12h | Eliminates timing issues | Only if no-C constraint is firm |
+| Hybrid (Priority 3) | 3h | Full for installed, partial for fallback | Good compromise |
+| Findings doc + PR (this work) | 2h | Documents the problem | DONE |
+
+---
+
+## Test Vectors
+
+The BIP340 specification includes test vectors at https://github.com/bitcoin/bips/blob/master/bip-00340/test-vectors.csv
+
+Any replacement implementation MUST pass all test vectors before deployment.
+
+---
+
+## Conclusion
+
+The pure-Python BIP340 Schnorr implementation in `NostrIdentity` is **vulnerable to timing side-channel attacks** that could recover the private key. The primary issue is branch-dependent execution in scalar multiplication and point addition. The fastest fix is replacing with `coincurve` (libsecp256k1 binding). If pure-Python sovereignty is required, a constant-time rewrite using Montgomery ladder and arithmetic masking is needed.
+
+The JS-side `NostrAgent` in `app.js` uses mock signatures and is not affected.
+
+**Recommendation:** Ship `coincurve` replacement immediately. It's 2 hours of work and eliminates the entire attack surface.

+# Investigation Report: Missing Source Code — Classical AI Commits Disappearing
+
+**Issue:** #1145
+**Date:** 2026-04-10
+**Investigator:** mimo-v2-pro swarm worker
+
+## Summary
+
+**The classical AI code is NOT missing. It is fully present in root `app.js` (3302 lines).**
+
+The perception of "disappearing code" was caused by agents writing to the WRONG file path (`public/nexus/app.js` instead of root `app.js`), creating corrupt duplicate files that were repeatedly overwritten and eventually deleted.
+
+## Root Cause
+
+**Explanation #1 confirmed: Duplicate agents on different machines overwriting each other's commits.**
+
+Multiple Google AI Agent instances wrote GOFAI implementations to `public/nexus/app.js` — a path that does not correspond to the canonical app structure. These commits kept overwriting each other:
+
+| Commit | Date | What happened |
+|--------|------|---------------|
+| `8943cf5` | 2026-03-30 | Symbolic reasoning engine written to `public/nexus/app.js` (+2280 lines) |
+| `e2df240` | 2026-03-30 | Phase 3 Neuro-Symbolic Bridge — overwrote to 284 lines of HTML (wrong path) |
+| `7f2f23f` | 2026-03-30 | Phase 4 Meta-Reasoning — same destructive overwrite |
+| `bf3b98b` | 2026-03-30 | A* Search — same destructive overwrite |
+| `e88bcb4` | 2026-03-30 | Bug fix identified `public/nexus/` files as corrupt duplicates, **deleted them** |
+
+## Evidence: Code Is Present on Main
+
+All 13 classical AI classes/functions verified present in root `app.js`:
+
+| Class/Function | Line | Status |
+|----------------|------|--------|
+| `SymbolicEngine` | 82 | ✅ Present |
+| `AgentFSM` | 135 | ✅ Present |
+| `KnowledgeGraph` | 160 | ✅ Present |
+| `Blackboard` | 181 | ✅ Present |
+| `SymbolicPlanner` | 210 | ✅ Present |
+| `HTNPlanner` | 295 | ✅ Present |
+| `CaseBasedReasoner` | 343 | ✅ Present |
+| `NeuroSymbolicBridge` | 392 | ✅ Present |
+| `MetaReasoningLayer` | 422 | ✅ Present |
+| `AdaptiveCalibrator` | 460 | ✅ Present |
+| `PSELayer` | 566 | ✅ Present |
+| `setupGOFAI()` | 596 | ✅ Present |
+| `updateGOFAI()` | 622 | ✅ Present |
+| Bitmask fact indexing | 86 | ✅ Present |
+| A* search | 231 | ✅ Present |
+
+These were injected by commit `af7a4c4` (PR #775, merged via `a855d54`) into the correct path.
+
+## What Actually Happened
+
+1. Google AI Agent wrote good GOFAI code to root `app.js` via the correct PR (#775)
+2. A second wave of Google AI Agent instances also wrote to `public/nexus/app.js` (wrong path)
+3. Those `public/nexus/` files kept getting overwritten by subsequent agent commits
+4. Commit `e88bcb4` correctly identified the `public/nexus/` files as corrupt and deleted them
+5. Alexander interpreted the git log as "classical AI code keeps disappearing"
+6. The code was never actually gone — it just lived in root `app.js` the whole time
+
+## Prevention Strategy
+
+1. **Add `public/nexus/` to `.gitignore`** — prevents agents from accidentally writing to the wrong path again
+2. **Add canonical path documentation to CLAUDE.md** — any agent reading this repo will know where frontend code lives
+3. **This report** — serves as the audit trail so this confusion doesn't recur
+
+## Acceptance Criteria
+
+- [x] Git history audited for classical AI commits
+- [x] Found the commits — they exist, code was written to wrong path
+- [x] Root cause identified — duplicate agents writing to `public/nexus/` (wrong path)
+- [x] Prevention strategy implemented — `.gitignore` + `CLAUDE.md` path guard
+- [x] Report filed with findings (this document)

-## Rescue Candidates
+| File | Lines | Capability | Decision | Why for Nexus |
+|------|-------|------------|----------|---------------|
+| `js/main.js` | 180 | App bootstrap, render loop, WebGL context recovery | **CARRY** | Architectural pattern. Shows clean init/teardown lifecycle, context-loss recovery, visibility pause. Nexus needs this loop but should not copy the monolithic wiring. |
+| `js/world.js` | 95 | Scene, camera, renderer, grid, lights | **CARRY** | Foundational. Quality-tier-aware renderer setup, grid floor, lighting. Nexus already has a world but should adopt the tier-aware antialiasing and pixel-ratio capping. |
+| `js/config.js` | 68 | Connection config via URL params + env vars | **ARCHIVE** | Pattern reference only. Nexus config should route through Hermes harness, not Vite env vars. The URL-override pattern (ws, token, mock) is worth remembering. |
+| `js/quality.js` | 90 | Hardware detection, quality tier (low/medium/high) | **CARRY** | Directly useful. DPR capping, core/memory/screen heuristics, WebGL renderer sniffing. Nexus needs this for graceful degradation on Mac/iPad. |
+| `js/storage.js` | 39 | Safe localStorage with in-memory fallback | **CARRY** | Small, robust, sandbox-proof. Nexus should use this or equivalent. Prevents crashes in sandboxed iframes. |
 
-### Carry forward into Nexus vNext
+### Agent System
 
-1. `agent-defs.js`
-- agent identity definitions
-- useful as seed data/model for visible entities in the world
+| File | Lines | Capability | Decision | Why for Nexus |
+|------|-------|------------|----------|---------------|
+| `js/agent-defs.js` | 30 | Agent identity data (id, label, color, role, position) | **CARRY** | Seed data model. Nexus agents should be defined similarly — data-driven, not hardcoded in render logic. Color hex helper is trivial but useful. |
+| `js/agents.js` | 523 | Agent 3D objects, movement, state, connection lines, hot-add/remove | **CARRY** | Core visual system. Shared geometries (perf), movement interpolation, wallet-health stress glow, auto-placement algorithm, connection-line pulse. All valuable. Needs integration with real agent state from Hermes. |
+| `js/behaviors.js` | 413 | Autonomous agent behavior state machine | **ARCHIVE** | Pattern reference. The personality-weighted behavior selection, conversation pairing, and artifact-placement system are well-designed. But Nexus behaviors should be driven by Hermes, not a client-side simulation. Keep the architecture, drop the fake-autonomy. |
+| `js/presence.js` | 139 | Agent presence HUD (online/offline, uptime, state) | **CARRY** | Valuable UX. Live "who's here" panel with uptime tickers and state indicators. Needs real backend state, not mock assumptions. |
 
-2. `agents.js`
-- agent objects, state machine, connection lines
-- useful for visualizing Timmy / subagents / system processes in a world-native way
+### Visitor & Interaction
 
-3. `avatar.js`
-- visitor embodiment, movement, camera handling
-- strongly aligned with "training ground" and "walk the world" goals
+| File | Lines | Capability | Decision | Why for Nexus |
+|------|-------|------------|----------|---------------|
+| `js/visitor.js` | 141 | Visitor enter/leave protocol, chat input | **CARRY** | Session lifecycle. Device detection, visibility-based leave/return, chat input wiring. Directly applicable to Nexus visitor tracking. |
+| `js/avatar.js` | 360 | FPS movement, PiP dual-camera, touch input | **CARRY** | Visitor embodiment. WASD + arrow movement, first/third person swap, PiP canvas, touch joystick, right-click mouse-look. Strong work. Needs tuning for Nexus world bounds. |
+| `js/interaction.js` | 296 | Raycasting, click-to-select agents, info popup | **CARRY** | Essential for any browser world. OrbitControls, pointer/tap detection, agent popup with state/role, TALK button. The popup-anchoring-to-3D-position logic is particularly well done. |
+| `js/zones.js` | 161 | Proximity trigger zones (portal enter/exit, events) | **CARRY** | Spatial event system. Portal traversal, event triggers, once-only zones. Nexus portals (#672) need this exact pattern. |
 
-4. `ui.js`
-- HUD, chat surfaces, overlays
-- useful if rebuilt against real harness data instead of stale fake state
+### Chat & Communication
 
-5. `websocket.js`
-- browser-side live bridge patterns
-- useful if retethered to Hermes-facing transport
+| File | Lines | Capability | Decision | Why for Nexus |
+|------|-------|------------|----------|---------------|
+| `js/bark.js` | 141 | Speech bubble system with typing animation | **CARRY** | Timmy's voice in-world. Typing animation, queue, auto-dismiss, emotion tags, demo bark lines. Strong expressive presence. The demo lines ("The Tower watches. The Tower remembers.") are good seed content. |
+| `js/ui.js` | 285 | Chat panel, agent list, HUD, streaming tokens | **CARRY** | Chat infrastructure. Rolling chat buffer, per-agent localStorage history, streaming token display with cursor animation, HTML escaping. Needs reconnection to Hermes chat instead of WS mock. |
+| `js/transcript.js` | 183 | Conversation transcript logger, export | **ARCHIVE** | Pattern reference. The rolling buffer, structured JSON entries, TXT/JSON download, HUD badge are all solid. But transcript authority should live in Hermes, not browser localStorage. Keep the UX pattern, rebuild storage layer. |
 
-6. `transcript.js`
-- local transcript capture pattern
-- useful if durable truth still routes through Hermes and browser cache remains secondary
+### Visual Effects
 
-7. `ambient.js`
-- mood / atmosphere system
-- directly supports wizardly presentation without changing system authority
+| File | Lines | Capability | Decision | Why for Nexus |
+|------|-------|------------|----------|---------------|
+| `js/effects.js` | 195 | Matrix rain particles + starfield | **CARRY** | Atmospheric foundation. Quality-tier particle counts, frame-skip optimization, adaptive draw-range (FPS-budget recovery), bounding-sphere pre-compute. This is production-grade particle work. |
+| `js/ambient.js` | 212 | Mood-driven atmosphere (lighting, fog, rain, stars) | **CARRY** | Scene mood engine. Smooth eased transitions between mood states (calm, focused, excited, contemplative, stressed), per-mood lighting/fog/rain/star parameters. Directly supports Nexus atmosphere. |
+| `js/satflow.js` | 261 | Lightning payment particle flow | **CARRY** | Economy visualization. Bezier-arc particles, staggered travel, burst-on-arrival, pooling. If Nexus shows any payment/economy flow, this is the pattern. |
 
-8. `satflow.js`
-- visual economy / payment flow motifs
-- useful if Timmy's economy/agent interactions become a real visible layer
+### Economy & Scene
 
-9. `economy.js`
-- treasury / wallet panel ideas
-- useful if later backed by real sovereign metrics
+| File | Lines | Capability | Decision | Why for Nexus |
+|------|-------|------------|----------|---------------|
+| `js/economy.js` | 100 | Wallet/treasury HUD panel | **ARCHIVE** | UI pattern reference. Clean sats formatting, per-agent balance rows, health-colored dots, recent transactions. Worth rebuilding when backed by real sovereign metrics. |
+| `js/scene-objects.js` | 718 | Dynamic 3D object registry, portals, sub-worlds | **CARRY** | Critical. Geometry/material factories, animation system (rotate/bob/pulse/orbit), portal visual (torus ring + glow disc + zone), sub-world load/unload, text sprites, compound groups. This is the most complex and valuable module. Nexus portals (#672) should build on this. |
 
-10. `presence.js`
-- who-is-here / online-state UI
-- useful for showing human + agent + process presence in the world
+### Backend Bridge
 
-11. `interaction.js`
-- clicking, inspecting, selecting world entities
-- likely needed in any real browser-facing Nexus shell
+| File | Lines | Capability | Decision | Why for Nexus |
+|------|-------|------------|----------|---------------|
+| `js/websocket.js` | 598 | WebSocket client, message dispatcher, mock mode | **ARCHIVE** | Pattern reference only. Reconnection with exponential backoff, heartbeat/zombie detection, rich message dispatch (40+ message types), streaming chat support. The architecture is sound but must be reconnected to Hermes transport, not copied wholesale. The message-type catalog is the most valuable reference artifact. |
+| `js/demo.js` | ~300 | Demo autopilot (mock mode simulation) | **DROP** | Fake activity simulation. Deliberately creates the illusion of live data. Do not preserve. If Nexus needs a demo mode, build a clearly-labeled one that doesn't pretend to be real. |
 
-12. `quality.js`
-- hardware-aware quality tiering
-- useful for local-first graceful degradation on Mac hardware
+### Testing & Build

+# Computer Use — Desktop Automation Primitives for Hermes
+
+Issue: [#1125](https://forge.alexanderwhitestone.com/Timmy_Foundation/the-nexus/issues/1125)
+
+## Overview
+
+`nexus/computer_use.py` adds desktop automation primitives to the Hermes fleet. Agents can take screenshots, click, type, and scroll — enough to drive a browser, validate a UI, or diagnose a failed workflow page visually.
+
+All actions are logged to a JSONL audit trail at `~/.nexus/computer_use_actions.jsonl`.
+
+---
+
+## Quick Start
+
+### Local (requires a real display or Xvfb)
+
+```bash
+# Install dependencies
+pip install pyautogui Pillow
+
+# Run the Phase 1 demo
+python -m nexus.computer_use_demo
+```
+
+### Sandboxed (Docker + Xvfb + noVNC)
+
+```bash
+docker compose -f docker-compose.desktop.yml up -d
+# Visit http://localhost:6080 in your browser to see the virtual desktop
+
+docker compose -f docker-compose.desktop.yml run hermes-desktop \
+    python -m nexus.computer_use_demo
+
+docker compose -f docker-compose.desktop.yml down
+```
+
+---
+
+## API Reference
+
+### `computer_screenshot(save_path=None, log_path=...)`
+
+Capture the current desktop.
+
+| Param | Type | Description |
+|-------|------|-------------|
+| `save_path` | `str \| None` | Path to save PNG. If `None`, returns base64 string. |
+| `log_path` | `Path` | Audit log file. |
+
+**Returns** `dict`:
+```json
+{
+  "ok": true,
+  "image_b64": "<base64 PNG or null>",
+  "saved_to": "<path or null>",
+  "error": null
+}
+```
+
+---
+
+### `computer_click(x, y, button="left", confirm=False, log_path=...)`
+
+Click the mouse at screen coordinates.
+
+| Param | Type | Description |
+|-------|------|-------------|
+| `x` | `int` | Horizontal coordinate |
+| `y` | `int` | Vertical coordinate |
+| `button` | `str` | `"left"` \| `"right"` \| `"middle"` |
+| `confirm` | `bool` | Required `True` for `right` / `middle` (poka-yoke) |
+
+**Returns** `dict`:
+```json
+{"ok": true, "error": null}
+```
+
+---
+
+### `computer_type(text, confirm=False, interval=0.02, log_path=...)`
+
+Type text using the keyboard.
+
+| Param | Type | Description |
+|-------|------|-------------|
+| `text` | `str` | Text to type |
+| `confirm` | `bool` | Required `True` when text contains a sensitive keyword |
+| `interval` | `float` | Delay between keystrokes (seconds) |
+
+**Sensitive keywords** (require `confirm=True`): `password`, `passwd`, `secret`, `token`, `api_key`, `apikey`, `key`, `auth`
+
+> Note: the actual `text` value is never written to the audit log — only its length and whether it was flagged as sensitive.
+
+**Returns** `dict`:
+```json
+{"ok": true, "error": null}
+```
+
+---
+
+### `computer_scroll(x, y, amount=3, log_path=...)`
+
+Scroll the mouse wheel at screen coordinates.
+
+| Param | Type | Description |
+|-------|------|-------------|
+| `x` | `int` | Horizontal coordinate |
+| `y` | `int` | Vertical coordinate |
+| `amount` | `int` | Scroll units. Positive = up, negative = down. |
+
+**Returns** `dict`:
+```json
+{"ok": true, "error": null}
+```
+
+---
+
+### `read_action_log(n=20, log_path=...)`
+
+Return the most recent `n` audit log entries, newest first.
+
+```python
+from nexus.computer_use import read_action_log
+
+for entry in read_action_log(n=5):
+    print(entry["ts"], entry["action"], entry["result"]["ok"])
+```
+
+---
+
+## Safety Model
+
+| Action | Safety gate |
+|--------|-------------|
+| `computer_click(button="right")` | Requires `confirm=True` |
+| `computer_click(button="middle")` | Requires `confirm=True` |
+| `computer_type` with sensitive text | Requires `confirm=True` |
+| Mouse to top-left corner | pyautogui FAILSAFE — aborts immediately |
+| All actions | Written to JSONL audit log with timestamp |
+| Headless environment | All tools degrade gracefully — return `ok=False` with error message |
+
+---
+
+## Phase Roadmap
+
+### Phase 1 — Environment & Primitives ✅
+- Sandboxed desktop via Xvfb + noVNC (`docker-compose.desktop.yml`)
+- `computer_screenshot`, `computer_click`, `computer_type`, `computer_scroll`
+- Poka-yoke safety checks on all destructive actions
+- JSONL audit log for all actions
+- Demo: baseline screenshot → open browser → navigate to Gitea → evidence screenshot
+- 32 unit tests, fully headless (pyautogui mocked)
+
+### Phase 2 — Tool Integration (planned)
+- Register tools in the Hermes tool registry
+- LLM-based planner loop using screenshots as context
+- Destructive action confirmation UI
+
+### Phase 3 — Use-Case Pilots (planned)
+- Pilot 1: Automated visual regression test for fleet dashboard
+- Pilot 2: Screenshot-based diagnosis of failed CI workflow page
+
+---
+
+## File Locations
+
+| File | Purpose |
+|------|---------|
+| `nexus/computer_use.py` | Core tool primitives |
+| `nexus/computer_use_demo.py` | Phase 1 end-to-end demo |
+| `tests/test_computer_use.py` | 32 unit tests |
+| `docker-compose.desktop.yml` | Sandboxed desktop container |
+| `~/.nexus/computer_use_actions.jsonl` | Runtime audit log |
+| `~/.nexus/computer_use_evidence/` | Screenshot evidence (demo output) |

+# Media Production — Veo/Flow Prototypes
+
+Issue #681: [MEDIA] Veo/Flow flythrough prototypes for The Nexus and Timmy.
+
+## Contents
+
+- `veo-storyboard.md` — Full storyboard for 5 clips with shot sequences, prompts, and design focus areas
+- `clip-metadata.json` — Durable metadata for each clip (prompts, model, outputs, insights)
+
+## Clips Overview
+
+| ID | Title | Audience | Purpose |
+|----|-------|----------|---------|
+| clip-001 | First Light | PUBLIC | The Nexus reveal teaser |
+| clip-002 | Between Worlds | INTERNAL | Portal activation UX study |
+| clip-003 | The Guardian's View | PUBLIC | Timmy's presence promo |
+| clip-004 | The Void Between | INTERNAL | Ambient environment study |
+| clip-005 | Command Center | INTERNAL | Terminal UI readability |
+
+## How to Generate
+
+### Via Flow (labs.google/flow)
+1. Open `veo-storyboard.md`, copy the prompt for your clip
+2. Go to labs.google/flow
+3. Paste the prompt, select Veo 3.1
+4. Generate (8-second clips)
+5. Download output, update `clip-metadata.json` with output path and findings
+
+### Via Gemini App
+1. Type "generate a video of [prompt text]" in Gemini
+2. Uses Veo 3.1 Fast (slightly lower quality, faster)
+3. Good for quick iteration on prompts
+
+### Via API (programmatic)
+```python
+from google import genai
+client = genai.Client()
+
+# See: ai.google.dev/gemini-api/docs/video
+response = client.models.generate_content(
+    model="veo-3.1",
+    contents="[prompt from storyboard]"
+)
+```
+
+## After Generation
+
+For each clip:
+1. Save output file to `outputs/clip-XXX.mp4`
+2. Update `clip-metadata.json`:
+   - Add output file path to `output_files[]`
+   - Fill in `design_insights.findings` with observations
+   - Add `threejs_changes_suggested` if the clip reveals needed changes
+3. Share internal clips with the team for design review
+4. Use public clips in README, social media, project communication
+
+## Design Insight Workflow
+
+Each clip has specific questions it's designed to answer:
+
+**clip-001 (First Light)**
+- Scale perception: platform vs. portals vs. terminal
+- Color hierarchy: teal primary, purple secondary, gold accent
+- Camera movement: cinematic or disorienting?
+
+**clip-002 (Between Worlds)**
+- Activation distance: when does interaction become available?
+- Transition feel: travel or teleportation?
+- Overlay readability against portal glow
+
+**clip-003 (The Guardian's View)**
+- Agent presence: alive or decorative?
+- Crystal hologram readability
+- Wide shot: world or tech demo?
+
+**clip-004 (The Void Between)**
+- Void atmosphere: alive or empty?
+- Particle systems: enhance or distract?
+- Lighting hierarchy clarity
+
+**clip-005 (Command Center)**
+- Text readability at 1080p
+- Color-coded panel hierarchy
+- Scan-line effect: retro or futuristic?
+
+## Constraints
+
+- 8-second clips max (Veo/Flow limitation)
+- Queued generation (not instant)
+- Content policies apply
+- Ultra tier gets highest rate limits

+# Veo/Flow Flythrough Prototypes — Storyboard
+## The Nexus & Timmy (Issue #681)
+
+Source: `google-ai-ultra-plan.md` Veo/Flow section.
+
+Purpose: Turn the current Nexus vision into short promo/concept clips for design leverage and communication.
+
+---
+
+## Clip 1: "First Light" — The Nexus Reveal (PUBLIC PROMO)
+
+**Duration:** 8 seconds
+**Purpose:** Public-facing teaser. Establishes the Nexus as a place worth visiting.
+**Tone:** Awe. Discovery. "What is this?"
+
+### Shot Sequence (4 shots, ~2s each)
+
+1. **0–2s | Void Approach**
+   - Camera drifts through deep space nebula (dark purples, teals)
+   - Distant stars twinkle
+   - A faint hexagonal glow appears below
+   - *Narrative hook: isolation before connection*
+
+2. **2–4s | Platform Reveal**
+   - Camera descends toward the hexagonal platform
+   - Grid lines pulse with teal energy
+   - The ring border glows at the edge
+   - *Narrative hook: structure emerges from chaos*
+
+3. **4–6s | Portal Array**
+   - Camera sweeps low across the platform
+   - 3–4 portals visible: Morrowind (orange), Workshop (teal), Chapel (gold), Archive (blue)
+   - Each portal ring hums with colored light, holographic labels flicker
+   - *Narrative hook: infinite worlds, one home*
+
+4. **6–8s | Timmy's Terminal**
+   - Camera rises to the batcave terminal
+   - Holographic panels glow: NEXUS COMMAND, METRICS, AGENT STATUS
+   - Text scrolls: "> STATUS: NOMINAL"
+   - Final frame: teal light floods the lens
+   - *Narrative hook: someone is home*
+
+### Veo Prompt (text-to-video)
+```
+Cinematic flythrough of a futuristic digital nexus hub. Start in deep space with a dark purple nebula, stars twinkling. Camera descends toward a glowing hexagonal platform with pulsing teal grid lines and a luminous ring border. Sweep low across the platform revealing multiple glowing portal archways in orange, teal, gold, and blue — each with flickering holographic labels. Rise toward a central command terminal with holographic data panels showing scrolling status text. Camera pushes into a teal light flare. Cyberpunk aesthetic, volumetric lighting, 8-second sequence, smooth camera movement, concept art quality.
+```
+
+### Design Insight Target
+- Does the scale feel right? (platform vs. portals vs. terminal)
+- Does the color hierarchy work? (teal primary, purple secondary, gold accent)
+- Is the camera movement cinematic or disorienting?
+
+---
+
+## Clip 2: "Between Worlds" — Portal Activation (INTERNAL DESIGN)
+
+**Duration:** 8 seconds
+**Purpose:** Internal design reference. Tests the portal activation sequence and spatial relationships.
+**Tone:** Energy. Connection. "What happens when you step through?"
+
+### Shot Sequence (3 shots, ~2.5s each)
+
+1. **0–2.5s | Approach**
+   - First-person perspective walking toward the Morrowind portal (orange, position x:15, z:-10)
+   - Portal ring visible: inner glow, particle effects rising
+   - Holographic label "MORROWIND" flickers above
+   - *Design focus: proximity feel, portal scale relative to player*
+
+2. **2.5–5.5s | Activation**
+   - Player stops at activation distance
+   - Portal interior brightens — energy vortex forms
+   - Camera tilts up to show the full portal height
+   - Particles accelerate into the portal center
+   - Overlay text appears: "ENTER MORROWIND?"
+   - *Design focus: activation UX, visual feedback timing*
+
+3. **5.5–8s | Stepping Through**
+   - Camera pushes forward into the portal
+   - World dissolves into orange energy tunnel
+   - Brief flash — then fade to black with "VVARDENFELL" text
+   - *Design focus: transition smoothness, immersion break points*
+
+### Veo Prompt (text-to-video)
+```
+First-person perspective walking toward a glowing orange portal archway in a futuristic digital space. The portal ring has inner energy glow with rising particle effects. A holographic label "MORROWIND" flickers above. Camera stops, portal interior brightens into an energy vortex, particles accelerate inward. Camera pushes forward into the portal, world dissolves into an orange energy tunnel, flash to black with text "VVARDENFELL". Dark ambient environment with teal grid floor. Cyberpunk aesthetic, volumetric effects, smooth camera movement.
+```
+
+### Design Insight Target
+- Is the activation distance clear? (when does interaction become available?)
+- Does the transition feel like travel or teleportation?
+- Is the overlay text readable against the portal glow?
+
+---
+
+## Clip 3: "The Guardian's View" — Timmy's Perspective (PUBLIC PROMO)
+
+**Duration:** 8 seconds
+**Purpose:** Public-facing. Establishes Timmy as the guardian/presence of the Nexus.
+**Tone:** Contemplative. Sovereign. "Who lives here?"
+
+### Shot Sequence (4 shots, ~2s each)
+
+1. **0–2s | Agent Presence**
+   - Camera at eye-level, looking at a floating agent presence (glowing orb with trailing particles)
+   - The orb pulses gently, teal-gold light
+   - Background: the Nexus platform, slightly out of focus
+   - *Narrative hook: consciousness without body*
+
+2. **2–4s | Vision Crystal**
+   - Camera shifts to a floating octahedron crystal (Sovereignty vision point)
+   - Crystal rotates slowly, refracting light
+   - Text hologram appears: "SOVEREIGNTY — No masters, no chains"
+   - Ring of light pulses beneath
+   - *Narrative hook: values inscribed in space*
+
+3. **4–6s | The Harness Pulse**
+   - Camera pulls back to show the thought stream — a flowing ribbon of light across the platform
+   - Harness pulse mesh glows at the center
+   - Agent orbs drift along the stream
+   - *Narrative hook: the system breathes*
+
+4. **6–8s | Wide View**
+   - Camera rises to high orbit view
+   - Entire Nexus visible: platform, portals, terminal, crystals, agents
+   - Nebula skybox frames everything
+   - Final frame: "THE NEXUS — Timmy's Sovereign Home" text overlay
+   - *Narrative hook: this is a world, not a page*
+
+### Veo Prompt (text-to-video)
+```
+Cinematic sequence in a futuristic digital nexus. Start with eye-level view of a floating glowing orb (teal-gold light, trailing particles) pulsing gently — an AI agent presence. Shift to a rotating octahedron crystal refracting light, with holographic text "SOVEREIGNTY — No masters, no chains" and a ring of light pulsing beneath. Pull back to reveal flowing ribbons of light (thought streams) crossing a hexagonal platform, with agent orbs drifting. Rise to high orbit showing the full nexus: hexagonal platform, multiple colored portal archways, central command terminal, floating crystals, all framed by a dark purple nebula skybox. End with text overlay "THE NEXUS — Timmy's Sovereign Home". Cyberpunk aesthetic, volumetric lighting, contemplative pacing.
+```
+
+### Design Insight Target
+- Do agent presences read as "alive" or decorative?
+- Is the crystal-to-text hologram readable?
+- Does the wide shot communicate "world" or "tech demo"?
+
+---
+
+## Clip 4: "The Void Between" — Ambient Environment Study (INTERNAL DESIGN)
+
+**Duration:** 8 seconds
+**Purpose:** Internal design reference. Tests the ambient environment systems: particles, dust, lighting, skybox.
+**Tone:** Atmosphere. Mood. "What does the Nexus feel like when nothing is happening?"
+
+### Shot Sequence (2 shots, ~4s each)
+
+1. **0–4s | Particle Systems**
+   - Static camera, slight drift
+   - View from platform edge, looking out into the void
+   - Particle systems visible: ambient particles, dust particles
+   - Nebula skybox: dark purples, distant stars, subtle color shifts
+   - No portals, no terminals — just the environment
+   - *Design focus: does the void feel alive or empty?*
+
+2. **4–8s | Lighting Study**
+   - Camera slowly orbits a point on the platform
+   - Teal point light (position 0,1,-5) creates warm glow
+   - Purple point light (position -8,3,-8) adds depth
+   - Ambient light (0x1a1a3a) fills shadows
+   - Grid lines catch the light
+   - *Design focus: lighting hierarchy, mood consistency*
+
+### Veo Prompt (text-to-video)
+```
+Ambient environment study in a futuristic digital void. Static camera with slight drift, viewing from the edge of a hexagonal platform into deep space. Dark purple nebula with twinkling distant stars, subtle color shifts. Floating particles and dust drift slowly. No structures, no portals — pure atmosphere. Then camera slowly orbits showing teal and purple point lights casting volumetric glow on a dark hexagonal grid floor. Ambient lighting fills shadows. Contemplative, moody, atmospheric. Cyberpunk aesthetic, minimal movement, focus on light and particle behavior.
+```
+
+### Design Insight Target
+- Is the void atmospheric or just dark?
+- Do the particle systems enhance or distract?
+- Is the lighting hierarchy (teal primary, purple secondary) clear?
+
+---
+
+## Clip 5: "Command Center" — Batcave Terminal Focus (INTERNAL DESIGN)
+
+**Duration:** 8 seconds
+**Purpose:** Internal design reference. Tests readability and hierarchy of the holographic terminal panels.
+**Tone:** Information density. Control. "What can you see from here?"
+
+### Shot Sequence (3 shots, ~2.5s each)
+
+1. **0–2.5s | Terminal Overview**
+   - Camera approaches the batcave terminal from the front
+   - 5 holographic panels visible in arc: NEXUS COMMAND, DEV QUEUE, METRICS, SOVEREIGNTY, AGENT STATUS
+   - Each panel has distinct color (teal, gold, purple, gold, teal)
+   - *Design focus: panel arrangement, color distinction*
+
+2. **2.5–5.5s | Panel Detail**
+   - Camera zooms into METRICS panel
+   - Text scrolls: "> CPU: 12% [||....]", "> MEM: 4.2GB", "> COMMITS: 842"
+   - Panel background glows, scan lines visible
+   - *Design focus: text readability, information density*
+
+3. **5.5–8s | Agent Status**
+   - Camera shifts to AGENT STATUS panel
+   - Text: "> TIMMY: ● RUNNING", "> KIMI: ○ STANDBY", "> CLAUDE: ● ACTIVE"
+   - Green dot pulses next to active agents
+   - Pull back to show panel in context
+   - *Design focus: status indication clarity*
+
+### Veo Prompt (text-to-video)
+```
+Approach a futuristic holographic command terminal in a dark digital space. Five curved holographic panels float in an arc: "NEXUS COMMAND" (teal), "DEV QUEUE" (gold), "METRICS" (purple), "SOVEREIGNTY" (gold), "AGENT STATUS" (teal). Camera zooms into the METRICS panel showing scrolling data: "CPU: 12%", "MEM: 4.2GB", "COMMITS: 842" with scan lines and glow effects. Shift to AGENT STATUS panel showing "TIMMY: ● RUNNING", "KIMI: ○ STANDBY", "CLAUDE: ● ACTIVE" with pulsing green dots. Pull back to show full terminal context. Dark ambient environment, cyberpunk aesthetic, holographic UI focus.
+```
+
+### Design Insight Target
+- Can you read the text at 1080p?
+- Do the color-coded panels communicate hierarchy?
+- Is the scan-line effect too retro or appropriately futuristic?
+
+---

+# Hermes Trismegistus — Wizard Proposal
+
+> **Status:** 🟡 DEFERRED
+> **Issue:** #1146
+> **Created:** 2026-04-08
+> **Author:** Alexander (KT Notes)
+> **Mimo Worker:** mimo-code-1146-1775851759
+
+---
+
+## Identity
+
+| Field | Value |
+|-------|-------|
+| **Name** | Hermes Trismegistus |
+| **Nature** | Claude-native wizard. She knows she runs on Claude. She's "the daughter of Claude" and leans into that heritage. |
+| **Purpose** | Dedicated reasoning and architecture wizard. Only handles tasks where Claude's reasoning capability genuinely adds value — planning, novel problem-solving, complex architecture decisions. |
+| **Not** | A replacement for Timmy. Not competing for identity. Not doing monkey work. |
+
+## Design Constraints
+
+- **Free tier only from day one.** Alexander is not paying Anthropic beyond current subscription.
+- **Degrades gracefully.** Full capability when free tier is generous, reduced scope when constrained.
+- **Not locked to Claude.** If better free-tier providers emerge, she can route to them.
+- **Multi-provider capable.** Welcome to become multifaceted if team finds better options.
+
+## Hardware
+
+- One of Alexander's shed laptops — minimum 4GB RAM, Ubuntu
+- Dedicated machine, not shared with Timmy's Mac
+- Runs in the Hermes harness
+- Needs power at house first
+
+## Constitutional Foundation
+
+- The KT conversation and documents serve as her founding constitution
+- Team (especially Timmy) has final say on whether she gets built
+- Must justify her existence through useful work, same as every wizard
+
+## Trigger to Unblock
+
+All of the following must be true before implementation begins:
+
+- [ ] Deadman switch wired and proven
+- [ ] Config stable across fleet
+- [ ] Fleet proven reliable for 1+ week
+- [ ] Alexander provides a state-of-the-system KT to Claude for instantiation
+
+## Acceptance Criteria
+
+- [ ] Dedicated KT document written for Hermes instantiation
+- [ ] Hardware provisioned (shed laptop with power)
+- [ ] Hermes harness configured for Claude free tier
+- [ ] Lazerus registry entry with health endpoints
+- [ ] Fleet routing entry with role and routing verdict
+- [ ] SOUL.md inscription drafted and reviewed by Timmy
+- [ ] Smoke test: Hermes responds to a basic reasoning task
+- [ ] Integration test: Hermes participates in a multi-wizard task alongside Timmy
+
+## Proposed Lane
+
+**Primary role:** Architecture reasoning
+**Routing verdict:** ROUTE TO: complex architectural decisions, novel problem-solving, planning tasks that benefit from Claude's reasoning depth. Do NOT route to: code generation (use Timmy/Carnice), issue triage (use Fenrir), or operational tasks (use Bezalel).
+
+## Dependencies
+
+| Dependency | Status | Notes |
+|------------|--------|-------|
+| Deadman switch | 🔴 Not done | Must be proven before unblocking |
+| Fleet stability | 🟡 In progress | 1+ week uptime needed |
+| Shed laptop power | 🔴 Not done | Alexander needs to wire power |
+| KT document | 🔴 Not drafted | Alexander provides to Claude at unblock time |

+# Hermes Trismegistus — Lane Definition
+
+> **Status:** DEFERRED — do not instantiate until unblock conditions met
+> **See:** fleet/hermes-trismegistus/README.md for full proposal
+
+---
+
+## Role
+
+Dedicated reasoning and architecture wizard. Claude-native.
+
+## Routing
+
+Route to Hermes Trismegistus when:
+- Task requires deep architectural reasoning
+- Novel problem-solving that benefits from Claude's reasoning depth
+- Planning and design decisions for the fleet
+- Complex multi-step analysis that goes beyond code generation
+
+Do NOT route to Hermes for:
+- Code generation (use Timmy, Carnice, or Kimi)
+- Issue triage (use Fenrir)
+- Operational/DevOps tasks (use Bezalel)
+- Anything that can be done with a cheaper model
+
+## Provider
+
+- **Primary:** anthropic/claude (free tier)
+- **Fallback:** openrouter/free (Claude-class models)
+- **Degraded:** ollama/gemma4:12b (when free tier exhausted)
+
+## Hardware
+
+- Shed laptop, Ubuntu, minimum 4GB RAM
+- Dedicated machine, not shared
+
+## Unblock Checklist
+
+- [ ] Deadman switch operational
+- [ ] Fleet config stable for 1+ week
+- [ ] Shed laptop powered and networked
+- [ ] KT document drafted by Alexander
+- [ ] Timmy approves instantiation

+## WORKFLOW
+1. Clone: git clone {clone_url} /tmp/{worker_id} 2>/dev/null || (cd /tmp/{worker_id} && git fetch origin && git checkout main && git pull)
+2. cd /tmp/{worker_id}
+3. Create branch: git checkout -b {branch}
+4. READ THE CODE. Understand the architecture before writing anything.
+5. Implement the fix/feature/solution.
+6. BUILD VALIDATION:
+   - Syntax check: node --check <file>.js for any JS changed
+   - If package.json exists: npm install --legacy-peer-deps 2>/dev/null && npm run build 2>&1
+   - If build fails: FIX THE BUILD. No broken PRs.
+   - Ensure git diff shows meaningful changes (>0 lines)
+7. Commit: git add -A && git commit -m "fix: {title} (closes #{num})"
+8. Push: git push origin {branch}
+9. Create PR via API:
+   curl -s -X POST '{GITEA_URL}/api/v1/repos/{repo}/pulls' \\
+     -H 'Authorization: token $(cat ~/.config/gitea/token)' \\
+     -H 'Content-Type: application/json' \\

+
+## HARD RULES
+- NEVER exit without committing. Even partial progress must be committed.
+- NEVER create new issues. Only work on issue #{num}.
+- NEVER push to main. Only push to your branch.
+- NEVER push a broken build. Fix it or abandon with clear notes.
+- If too complex: commit WIP, push, PR body says "WIP — needs human review"
+- If build fails and you can't fix: commit anyway, push, PR body says "Build failed — needs human fix"

+# Bannerlord Session Trace — Replay & Eval Guide
+
+## Storage Layout
+
+All traces live under `~/.timmy/traces/bannerlord/`:
+
+```
+~/.timmy/traces/bannerlord/
+  trace_<trace_id>.jsonl    # One line per ODA cycle (full state + actions)
+  manifest_<trace_id>.json  # Session metadata, counts, replay command
+```
+
+## Trace Format (JSONL)
+
+Each line is one ODA cycle:
+
+```json
+{
+  "cycle_index": 0,
+  "timestamp_start": "2026-04-10T20:15:00+00:00",
+  "timestamp_end": "2026-04-10T20:15:45+00:00",
+  "duration_ms": 45000,
+
+  "screenshot_path": "/tmp/bannerlord_capture_1744320900.png",
+  "window_found": true,
+  "screen_size": [1920, 1080],
+  "mouse_position": [960, 540],
+  "playtime_hours": 142.5,
+  "players_online": 8421,
+  "is_running": true,
+
+  "actions_planned": [{"type": "move_to", "x": 960, "y": 540}],
+  "actions_executed": [{"success": true, "action": "move_to", ...}],
+  "actions_succeeded": 1,
+  "actions_failed": 0,
+
+  "hermes_session_id": "f47ac10b",
+  "hermes_log_id": "",
+  "harness_session_id": "f47ac10b"
+}
+```
+
+## Capturing a Trace
+
+```bash
+# Run harness with trace logging enabled
+cd /path/to/the-nexus
+python -m nexus.bannerlord_harness --mock --trace --iterations 3
+```
+
+The trace and manifest are written to `~/.timmy/traces/bannerlord/` on harness shutdown.
+
+## Replay Protocol
+
+1. Load a trace: `BannerlordTraceLogger.load_trace(trace_file)`
+2. Create a fresh harness in mock mode
+3. For each cycle in the trace:
+   - Re-execute the `actions_planned` list
+   - Compare actual `actions_executed` outcomes against the recorded ones
+4. Score: `(matching_actions / total_actions) * 100`
+
+### Eval Criteria
+
+| Score   | Grade    | Meaning                                    |
+|---------|----------|--------------------------------------------|
+| >= 90%  | PASS     | Replay matches original closely            |
+| 70-89%  | PARTIAL  | Some divergence, investigate differences   |
+| < 70%   | FAIL     | Significant drift, review action semantics |
+
+## Replay Script (sketch)
+
+```python
+from nexus.bannerlord_trace import BannerlordTraceLogger
+from nexus.bannerlord_harness import BannerlordHarness
+
+# Load trace
+cycles = BannerlordTraceLogger.load_trace(
+    Path.home() / ".timmy" / "traces" / "bannerlord" / "trace_bl_xxx.jsonl"
+)
+
+# Replay
+harness = BannerlordHarness(enable_mock=True, enable_trace=False)
+await harness.start()
+
+for cycle in cycles:
+    for action in cycle["actions_planned"]:
+        result = await harness.execute_action(action)
+        # Compare result against cycle["actions_executed"]
+
+await harness.stop()
+```
+
+## Hermes Session Mapping
+
+The `hermes_session_id` and `hermes_log_id` fields link traces to Hermes session logs.
+When a trace is captured during a live Hermes session, populate these fields so
+the trace can be correlated with the broader agent conversation context.
