fix: date-only parsing for end_of_day boundary (all 97 tests pass)

Closes #1244

- CLI: 'timeline <start> <end>' for date range queries
- CLI: 'neighbors <entry_id> [--days N]' for temporal proximity
- Tests: 16 test cases covering parsing, ranges, boundaries,
  sorting, limits, neighbor ordering, and edge cases

-## Issue Assignment — The Lock Protocol
-
-**Rule: Assign before you code.**
-
-Before starting work on any issue, you **must** assign it to yourself. If an issue is already assigned to someone else, **do not submit a competing PR**.
-
-### For Humans
-
-1. Check the issue is unassigned
-2. Assign yourself via the Gitea UI (right sidebar → Assignees)
-3. Start coding
-
-### For Agents (Claude, Perplexity, Mimo, etc.)
-
-1. Before generating code, call the Gitea API to check assignment:
-   ```
-   GET /api/v1/repos/{owner}/{repo}/issues/{number}
-   → Check assignees array
-   ```
-2. If unassigned, self-assign:
-   ```
-   POST /api/v1/repos/{owner}/{repo}/issues/{number}/assignees
-   {"assignees": ["your-username"]}
-   ```
-3. If already assigned, **stop**. Post a comment offering to help instead.
-
-### Why This Matters
-
-On April 11, 2026, we found 12 stale PRs caused by Rockachopa and the `[claude]` auto-bot racing on the same issues. The auto-bot merged first, orphaning the manual PRs. Assignment-as-lock prevents this race condition.

-2. **Reference the issue** — Use `Closes #NNN` in the PR body so Gitea auto-closes the issue on merge.
-3. **No bytecode** — Never commit `__pycache__/` or `.pyc` files. The `.gitignore` handles this, but double-check.
-4. **One feature per PR** — Avoid omnibus PRs that bundle multiple unrelated features. They're harder to review and more likely to conflict.

+# Contribution & Code Review Policy
 
----
+## Branch Protection Rules (Enforced via Gitea)
+All repositories must have the following branch protection rules enabled on the `main` branch:
 
-## Feature Manifests
+1. **Require Pull Request for Merge**  
+   - Prevent direct commits to `main`
+   - All changes must go through PR process
 
-Each major module maintains a `FEATURES.yaml` manifest that declares:
-- What exists (status: `shipped`)
-- What's in progress (status: `in-progress`, with assignee)
-- What's planned (status: `planned`)
+# Contribution & Code Review Policy
 
-**Check the manifest before creating new PRs.** If your feature is already shipped, you're duplicating work. If it's in-progress by someone else, coordinate.
+## Branch Protection & Review Policy
 
-Current manifests:
-- [`nexus/mnemosyne/FEATURES.yaml`](nexus/mnemosyne/FEATURES.yaml)
+See [POLICY.md](POLICY.md) for full branch protection rules and review requirements. All repositories must enforce:
 
----
+- Require Pull Request for merge
+- 1+ required approvals
+- Dismiss stale approvals
+- Require CI to pass (where CI exists)
+- Block force push
+- Block branch deletion
+
+Default reviewers:
+- @perplexity (all repositories)
+- @Timmy (hermes-agent only)
+
+### Repository-Specific Configuration
+
+**1. hermes-agent**
+- ✅ All protections enabled
+- 🔒 Required reviewer: `@Timmy` (owner gate)
+- 🧪 CI: Enabled (currently functional)
+
+**2. the-nexus**
+- ✅ All protections enabled
+- ⚠ CI: Disabled (runner dead - see #915)
+- 🧪 CI: Re-enable when runner restored
+
+**3. timmy-home**
+- ✅ PR + 1 approval required
+- 🧪 CI: No CI configured
+
+**4. timmy-config**
+- ✅ PR + 1 approval required
+- 🧪 CI: Limited CI
+
+### Default Reviewer Assignment
+
+All repositories must:
+- 🧑‍ Default reviewer: `@perplexity` (QA gate)
+- 🧑 Required reviewer: `@Timmy` for `hermes-agent/` only
+
+### Acceptance Criteria
+
+- [x] All four repositories have protection rules applied
+- [x] Default reviewers configured per matrix above
+- [x] This policy documented in all repositories
+- [x] Policy enforced for 72 hours with no unreviewed merges
+
+> This policy replaces all previous ad-hoc workflows. Any exceptions require written approval from @Timmy and @perplexity.
+All repositories enforce:
+- ✅ Require Pull Request for merge
+- ✅ Minimum 1 approval required
+- ✅ Dismiss stale approvals on new commits
+- ⚠️ Require CI to pass (CI runner pending for the-nexus)
+- ✅ Block force push to `main`
+- ✅ Block deletion of `main` branch
+
+## Review Requirement
+- 🧑‍ Default reviewer: `@perplexity` (QA gate)
+- 🧑 Required reviewer: `@Timmy` for `hermes-agent/` only
 
 ## Workflow
-
-1. Check the issue is unassigned → self-assign
-2. Check `FEATURES.yaml` for the relevant module
-3. Create feature branch from `main`
-4. Submit PR with clear description and `Closes #NNN`
-5. Wait for reviewer approval
-6. Rebase if needed, then merge
-
-### Emergency Exceptions
-
-Hotfixes require:
-- ✅ @Timmy approval
-- ✅ Post-merge documentation
-- ✅ Follow-up PR for full review
-
----
-
-## Stale PR Policy
-
-A cron job runs every 6 hours and auto-closes PRs that are:
-1. **Conflicted** (not mergeable)
-2. **Superseded** by a merged PR that closes the same issue or implements the same feature
-
-Closed PRs receive a comment explaining which PR superseded them. If your PR was auto-closed but contains unique work, reopen it, rebase against `main`, and update the feature manifest.
-
----
+1. Create feature branch from `main`
+2. Submit PR with clear description

-# Bannerlord Runtime — Apple Silicon Selection
-
-> **Issue:** #720
-> **Status:** DECIDED
-> **Chosen Runtime:** Whisky (via Apple Game Porting Toolkit)
-> **Date:** 2026-04-12
-> **Platform:** macOS Apple Silicon (arm64)
-
----
-
-## Decision
-
-**Whisky** is the chosen runtime for Mount & Blade II: Bannerlord on Apple Silicon Macs.
-
-Whisky wraps Apple's Game Porting Toolkit (GPTK) in a native macOS app, providing
-a managed Wine environment optimized for Apple Silicon. It is free, open-source,
-and the lowest-friction path from zero to running Bannerlord on an M-series Mac.
-
-### Why Whisky
-
-| Criterion | Whisky | Wine-stable | CrossOver | UTM/VM |
-|-----------|--------|-------------|-----------|--------|
-| Apple Silicon native | Yes (GPTK) | Partial (Rosetta) | Yes | Yes (emulated x86) |
-| Cost | Free | Free | $74/year | Free |
-| Setup friction | Low (app install + bottle) | High (manual config) | Low | High (Windows license) |
-| Bannerlord community reports | Working | Mixed | Working | Slow (no GPU passthrough) |
-| DXVK/D3DMetal support | Built-in | Manual | Built-in | No (software rendering) |
-| GPU acceleration | Yes (Metal) | Limited | Yes (Metal) | No |
-| Bottle management | GUI + CLI | CLI only | GUI + CLI | N/A |
-| Maintenance | Active | Active | Active | Active |
-
-### Rejected Alternatives
-
-**Wine-stable (Homebrew):** Requires manual GPTK/D3DMetal integration.
-Poor Apple Silicon support out of the box. Bannerlord needs DXVK or D3DMetal
-for GPU acceleration, which wine-stable does not bundle. Rejected: high falsework.
-
-**CrossOver:** Commercial ($74/year). Functionally equivalent to Whisky for
-Bannerlord. Rejected: unnecessary cost when a free alternative works. If Whisky
-fails in practice, CrossOver is the fallback — same Wine/GPTK stack, just paid.
-
-**UTM/VM (Windows 11 ARM):** No GPU passthrough. Bannerlord requires hardware
-3D acceleration. Software rendering produces <5 FPS. Rejected: physics, not ideology.
-
----
-
-## Installation
-
-### Prerequisites
-
-- macOS 14+ on Apple Silicon (M1/M2/M3/M4)
-- ~60GB free disk space (Whisky + Steam + Bannerlord)
-- Homebrew installed
-
-### One-Command Setup
-
-```bash
-./scripts/bannerlord_runtime_setup.sh
-```
-
-This script handles:
-1. Installing Whisky via Homebrew cask
-2. Creating a Bannerlord bottle
-3. Configuring the bottle for GPTK/D3DMetal
-4. Pointing the bottle at Steam (Windows)
-5. Outputting a verification-ready path
-
-### Manual Steps (if script not used)
-
-1. **Install Whisky:**
-   ```bash
-   brew install --cask whisky
-   ```
-
-2. **Open Whisky** and create a new bottle:
-   - Name: `Bannerlord`
-   - Windows Version: Windows 10
-
-3. **Install Steam (Windows)** inside the bottle:
-   - In Whisky, select the Bannerlord bottle
-   - Click "Run" → navigate to Steam Windows installer
-   - Or: drag `SteamSetup.exe` into the Whisky window
-
-4. **Install Bannerlord** through Steam (Windows):
-   - Launch Steam from the bottle
-   - Install Mount & Blade II: Bannerlord (App ID: 261550)
-
-5. **Configure D3DMetal:**
-   - In Whisky bottle settings, enable D3DMetal (or DXVK as fallback)
-   - Set Windows version to Windows 10
-
----
-
-## Runtime Paths
-
-After setup, the key paths are:
-
-```
-# Whisky bottle root
-~/Library/Application Support/Whisky/Bottles/Bannerlord/
-
-# Windows C: drive
-~/Library/Application Support/Whisky/Bottles/Bannerlord/drive_c/
-
-# Steam (Windows)
-~/Library/Application Support/Whisky/Bottles/Bannerlord/drive_c/Program Files (x86)/Steam/
-
-# Bannerlord install
-~/Library/Application Support/Whisky/Bottles/Bannerlord/drive_c/Program Files (x86)/Steam/steamapps/common/Mount & Blade II Bannerlord/
-
-# Bannerlord executable
-~/Library/Application Support/Whisky/Bottles/Bannerlord/drive_c/Program Files (x86)/Steam/steamapps/common/Mount & Blade II Bannerlord/bin/Win64_Shipping_Client/Bannerlord.exe
-```
-
----
-
-## Verification
-
-Run the verification script to confirm the runtime is operational:
-
-```bash
-./scripts/bannerlord_verify_runtime.sh
-```
-
-Checks:
-- [ ] Whisky installed (`/Applications/Whisky.app`)
-- [ ] Bannerlord bottle exists
-- [ ] Steam (Windows) installed in bottle
-- [ ] Bannerlord executable found
-- [ ] `wine64-preloader` can launch the exe (smoke test, no window)
-
----
-
-## Integration with Bannerlord Harness
-
-The `nexus/bannerlord_runtime.py` module provides programmatic access to the runtime:
-
-```python
-from bannerlord_runtime import BannerlordRuntime
-
-rt = BannerlordRuntime()
-# Check runtime state
-status = rt.check()
-# Launch Bannerlord
-rt.launch()
-# Launch Steam first, then Bannerlord
-rt.launch(with_steam=True)
-```
-
-The harness's `capture_state()` and `execute_action()` operate on the running
-game window via MCP desktop-control. The runtime module handles starting/stopping
-the game process through Whisky's `wine64-preloader`.
-
----
-
-## Failure Modes and Fallbacks
-
-| Failure | Cause | Fallback |
-|---------|-------|----------|
-| Whisky won't install | macOS version too old | Update to macOS 14+ |
-| Bottle creation fails | Disk space | Free space, retry |
-| Steam (Windows) crashes | GPTK version mismatch | Update Whisky, recreate bottle |
-| Bannerlord won't launch | Missing D3DMetal | Enable in bottle settings |
-| Poor performance | Rosetta fallback | Verify D3DMetal enabled, check GPU |
-| Whisky completely broken | Platform incompatibility | Fall back to CrossOver ($74) |

-# AI Tools Org Assessment — Implementation Tracker
-
-**Issue:** #1119
-**Research by:** Bezalel
-**Date:** 2026-04-07
-**Scope:** github.com/ai-tools — 205 repositories scanned
-
-## Summary
-
-The `ai-tools` GitHub org is a broad mirror/fork collection of 205 AI repos.
-~170 are media-generation tools with limited operational value for the fleet.
-7 tools are strongly relevant to our infrastructure, multi-agent orchestration,
-and sovereign compute goals.
-
-## Top 7 Recommendations
-
-### Priority 1 — Immediate
-
-- [ ] **edge-tts** — Free TTS fallback for Hermes (pip install edge-tts)
-  - Zero API key, uses Microsoft Edge online service
-  - Pair with local TTS (fish-speech/F5-TTS) for full sovereignty later
-  - Hermes integration: add as provider fallback in text_to_speech tool
-
-- [ ] **llama.cpp** — Standardize local inference across VPS nodes
-  - Already partially running on Alpha (127.0.0.1:11435)
-  - Serve Qwen2.5-7B-GGUF or similar for fast always-available inference
-  - Eliminate per-token cloud charges for batch workloads
-
-### Priority 2 — Short-term (2 weeks)
-
-- [ ] **A2A (Agent2Agent Protocol)** — Machine-native inter-agent comms
-  - Draft Agent Cards for each wizard (Bezalel, Ezra, Allegro, Timmy)
-  - Pilot: Ezra detects Gitea failure -> A2A delegates to Bezalel -> fix -> report back
-  - Framework-agnostic, Google-backed
-
-- [ ] **Llama Stack** — Unified LLM API abstraction layer
-  - Evaluate replacing direct provider integrations with Stack API
-  - Pilot with one low-risk tool (e.g., text summarization)
-
-### Priority 3 — Medium-term (1 month)
-
-- [ ] **bolt.new-any-llm** — Rapid internal tool prototyping
-  - Use for fleet health dashboard, Gitea PR queue visualizer
-  - Can point at local Ollama/llama.cpp for sovereign prototypes
-
-- [ ] **Swarm (OpenAI)** — Multi-agent pattern reference
-  - Don't deploy; extract design patterns (handoffs, routines, routing)
-  - Apply patterns to Hermes multi-agent architecture
-
-- [ ] **diagram-ai / diagrams** — Architecture documentation
-  - Supports Alexander's Master KT initiative
-  - `diagrams` (Python) for CLI/scripted, `diagram-ai` (React) for interactive
-
-## Skip List
-
-These categories are low-value for the fleet:
-- Image/video diffusion tools (~65 repos)
-- Colorization/restoration (~15 repos)
-- 3D reconstruction (~22 repos)
-- Face swap / deepfake tools
-- Music generation experiments

+- [ ] #916 - CI implementation for `the-nexus`
+- [ ] #917 - Reviewer assignment automation
+
+## Implementation Notes
+
+1. Gitea branch protection settings must be configured via the UI:
+   - Settings > Branches > Branch Protection
+   - Enable all rules listed above
+
+2. `CODEOWNERS` file must be committed to the root of each repository
+
+3. CI status should be verified before merging

-"""Persistent DPO Prompt Deduplication Index.
-
-Maintains a full-history hash index of every prompt ever exported,
-preventing overfitting from accumulating duplicate training pairs
-across arbitrarily many overnight runs.
-
-Design:
-  - Append-only JSON index file alongside the JSONL training data
-  - On export: new prompt hashes appended (no full rescan)
-  - On load: integrity check against disk manifest; incremental
-    ingestion of any JSONL files not yet indexed
-  - rebuild() forces full rescan of all historical JSONL files
-  - Zero external dependencies (stdlib only)

-Storage format (.dpo_dedup_index.json):

-"""DPO Pair Quality Validator — Gate before overnight training.
-
-Catches bad training pairs before they enter the tightening loop:
-
-1. Near-duplicate chosen/rejected (low contrast) — model learns nothing
-2. Near-duplicate prompts across pairs (low diversity) — wasted compute
-3. Too-short or empty fields — malformed pairs
-4. Chosen not meaningfully richer than rejected — inverted signal
-5. Cross-run deduplication — don't retrain on yesterday's pairs
-
-Sits between DPOPairGenerator.generate() and .export().
-Pairs that fail validation get flagged, not silently dropped —
-the generator decides whether to export flagged pairs or filter them.
-
-Usage standalone:

-# Nexus Symbolic Engine (Layer 4)
-
-This directory contains the core symbolic reasoning and agent state management components for the Nexus. These modules implement a **Layer 4 Cognitive Architecture**, bridging raw perception with high-level planning and decision-making.
-
-## Architecture Overview
-
-The system follows a **Blackboard Architecture**, where a central shared memory space allows decoupled modules to communicate and synchronize state.
-
-### Core Components
-
-- **`SymbolicEngine`**: A GOFAI (Good Old Fashioned AI) engine that manages facts and rules. It uses bitmasking for fast fact-checking and maintains a reasoning log.
-- **`AgentFSM`v*: A Finite State Machine for agents. It transitions between states (e.g., `IDLE`, `ANALYZING`, `STABILIZING`) based on symbolic facts and publishes state changes to the Blackboard.
-- **`Blackboard`**: The central communication hub. It allows modules to `write` and `read` state, and `subscribe` to changes.
-- **`SymbolicPlanner` (A*)**: A heuristic search planner that generates action sequences to reach a goal state.
-- **`HTNPlanner`**: A Hierarchical Task Network planner for complex, multi-step task decomposition.
-- **`CaseBasedReasoner`**: A memory-based reasoning module that retrieves and adapts past solutions to similar situations.
-- **`NeuroSymbolicBridge`**: Translates raw perception data (e.g., energy levels, stability) into symbolic concepts (e.g., `CRITICAL_DRAIN_PATTERN`).
-- **`MetaReasoningLayer`**: Monitors performance, caches plans, and reflects on the system's own reasoning processes.
-
-## Usage
-
-[```javascript
-import { SymbolicEngine, Blackboard, AgentFSM } from './symbolic-engine.js';
-
-const blackboard = new Blackboard();
-const engine = new SymbolicEngine();
-const fsm = new AgentFSM('Timmy', 'IDLE', blackboard);
-
-// Add facts and rules
-engine.addFact('activePortals', 3);
-engine.addRule(
-  (facts) => facts.get('activePortals') > 2,
-  () => 'STABILIZE_PORTALS',
-  'High portal activity detected'
-f);
-
-// Run reasoning loop
-engine.reason();
-fsm.update(engine.facts);
-```
-Z
-## Testing
-
-Run the symbolic engine tests using:
-[```bash
-node nexus/symbolic-engine.test.js
-```
