@@ -108,6 +108,54 @@ Flags:
108 - `--relays` adds explicit relay URLs, and `--default-relays=false` disables the public registry list for the current listing run.
109 - Unlike `portal expose`, `portal list` does not run the relay discovery expansion loop. It only resolves the registry seed list plus explicit `--relays` values.

111 +### `portal agent run [flags]`
112 +
113 +Runs Portal as a managed long-lived tunnel agent.
114 +
115 +- `portal agent run` reads the platform default config path, installs or updates the OS service, and opens the dashboard when run from an interactive terminal.
116 +- `portal agent run --config config.toml --foreground` runs the agent in the current terminal and opens the dashboard when the terminal is interactive.
117 +- `portal agent dashboard` attaches to an already running agent.
118 +- The service process owns multiple tunnel definitions from one `config.toml`.
119 +- The local control API is bound to loopback and authenticated with a token stored in the agent state directory.
120 +- `portal agent dashboard` opens the mouse-capable local TUI for tunnel add/delete, per-tunnel relay add/delete/listing, and multi-hop route changes.
121 +- `portal agent stop` asks the local agent to shut down, then disables/stops the OS service so intentional shutdown is not immediately restarted.
122 +- If the config file is missing, `portal agent run` creates a default config and the agent creates the identity file on first tunnel start.
123 +
124 +Default paths:
125 +
126 +| OS | Config | Default identity |
127 +|----|--------|------------------|
128 +| Linux user | `$XDG_CONFIG_HOME/portal-tunnel/agent/config.toml` or `~/.config/portal-tunnel/agent/config.toml` | `$XDG_DATA_HOME/portal-tunnel/agent/identity.json` or `~/.local/share/portal-tunnel/agent/identity.json` |
129 +| Linux root | `/etc/portal-tunnel/agent/config.toml` | `/var/lib/portal-tunnel/agent/identity.json` |
130 +| macOS user | `~/Library/Application Support/Portal Tunnel/Agent/config.toml` | `~/Library/Application Support/Portal Tunnel/Agent/identity.json` |
131 +| macOS root | `/Library/Application Support/Portal Tunnel/Agent/config.toml` | `/Library/Application Support/Portal Tunnel/Agent/identity.json` |
132 +| Windows | `%ProgramData%\Portal Tunnel\Agent\config.toml` | `%ProgramData%\Portal Tunnel\Agent\identity.json` |
133 +
134 +Example `config.toml`:
135 +
136 +```toml
137 +[agent]
138 +control_addr = "127.0.0.1:4018"
139 +service_name = "portal-agent"

151 Unlike `portal expose`, `portal list` does not run the relay discovery expansion loop. It only resolves the registry seed list plus explicit `--relays` values.
152
153 +### `portal agent`
154 +
155 +Run a durable local agent that owns multiple tunnels from one config file.
156 +
157 +```bash
158 +portal agent run
159 +portal agent dashboard
160 +portal agent stop
161 +```
162 +
163 +`portal agent run` reads or creates the platform default `config.toml`, installs or updates the OS-managed service, starts it, and opens the dashboard when invoked from an interactive terminal. Use `--foreground` for local debugging without service registration.
164 +Use `portal agent dashboard` to attach to an already running local agent. When using `--foreground`, keep that process running in one terminal and open the dashboard from another.
165 +
166 +**Subcommands:**
167 +
168 +| Command | Description |
169 +|---------|-------------|
170 +| `portal agent run` | Install/update and start the managed agent service |
171 +| `portal agent run --config config.toml --foreground` | Run the agent in the current terminal |
172 +| `portal agent dashboard` | Open the mouse-capable local TUI for tunnels, relay attach/detach, relay lists, and multi-hop route changes |
173 +| `portal agent stop` | Gracefully stop the agent and disable/stop the OS service |
174 +
175 +The local control API binds only to loopback and uses a token in the agent state directory. See [Configuration Reference](/configuration#configtoml) for the `config.toml` format.

1 +# Extended Stress Test Specification for MOLS-EWMA Policy
2 +
3 +This document outlines long-term stress test scenarios designed to validate the stability, scalability, and transposition accuracy of the EWMA-based relay selection policy.
4 +
5 +## 1. Scenario A: "The Messy Grid" (64x64 Non-Ideal Distribution)
6 +**Objective:** Validate transposition logic when relay density is non-optimal (not a perfect divisor of 64), which naturally occurs in fragmented network topologies.
7 +
8 +- **Setup:** 53 Relay URLs (not a power of 2, creating uneven GF(64) hash mapping).
9 +- **Network Stress:**
10 + - Inject "Micro-burst" RTT spikes (100ms duration, 800ms magnitude) every 30 seconds to 30% of nodes.
11 + - Validate that EWMA ($\alpha=0.3$) filters these spikes, preventing frequent priority flapping.
12 +- **Success Criteria:**
13 + - The system must prioritize the remaining 70% of stable nodes.
14 + - No "Priority Oscillation" where a node bounces between rank 1 and 5 every minute.
15 +
16 +## 2. Scenario B: "Massive Scale" (256 Node Pool)
17 +**Objective:** Validate performance and memory stability when the relay set significantly exceeds the standard 64-node MOLS grid.
18 +
19 +- **Setup:** 256 active Relay URLs.
20 +- **Network Stress:**
21 + - Perform a "Rolling Congestion" simulation: shift a 500ms+ latency penalty across groups of 32 nodes sequentially over a 24-hour period.
22 +- **Success Criteria:**
23 + - **Latency:** `rankRelayPool` execution time must remain < 5ms under the increased load.
24 + - **Stability:** The transposition logic should maintain a consistent set of the "top 3" healthiest nodes even as congestion rolls across the 256-node pool.
25 + - **Memory:** Telemetry counters (Prometheus gauge tracking) must not grow beyond the defined `boundedRelay` limit of 1024.
26 +
27 +## 3. Implementation Guidelines for `portal-loadtest`
28 +- **Simulation Duration:** All scenarios should run for a minimum of 24 hours to observe EWMA convergence.
29 +- **Telemetry Hook:** Integrate with the `portal/telemetry` package to log the `chi-square` uniformity metric every hour alongside the `EWMA RTT` distribution.
30 +- **Command:**
31 + ```bash
32 + # Scenario A
33 + make load-test -- -clients 500 -relays 53 -mode messy
34 +
35 + # Scenario B
36 + make load-test -- -clients 2000 -relays 256 -mode scale
37 + ```

1 +# MOLS EWMA & Percentile Transposition Performance Validation
2 +
3 +## 1. Overview
4 +We have upgraded the relay selection policy to incorporate not only EWMA-smoothed RTT but also percentile-based jitter analysis (p99 - p1). This multi-layered approach ensures that nodes are prioritized based on both central tendency (stability) and consistency (predictability).
5 +
6 +## 2. Methodology
7 +- **Percentile Tracking:** Each relay tracks the last 100 RTT samples.
8 +- **Jitter Scoring:** We calculate `Jitter = p99 - p1`.
9 +- **Transposition Criteria:** A relay is demoted if:
10 + - `EWMA RTT > 500ms` (persistent congestion) OR
11 + - `Jitter > 200ms` (high inconsistency/predictability risk)
12 +
13 +## 3. Performance Metrics (Simulated vs. Expected)
14 +
15 +| Metric | Threshold | Logic | Impact |
16 +| :--- | :--- | :--- | :--- |
17 +| **p50 (Median)** | < 100ms | Primary selection | Baseline low-latency path. |
18 +| **p99 (Tail)** | < 500ms | Transposition trigger | Prunes transient congestion spikes. |
19 +| **Jitter (p99-p1)**| < 200ms | Consistency filter | Eliminates "unpredictable" nodes. |
20 +
21 +## 4. Test Results (from `TestMOLSSelectPriorityEWMAStabilityTransposition`)
22 +The transposition logic was verified under a simulated scenario comparing a stable node against an inconsistent/high-jitter node.
23 +
24 +- **Stable Relay:** `EWMA=100ms`, `Jitter=20ms` -> **Ranked #1**
25 +- **Unstable Relay:** `EWMA=600ms`, `Jitter=300ms` -> **Ranked #2 (Demoted)**
26 +
27 +The engine successfully correctly identified and demoted the unstable node, even when their base MOLS scores were mathematically equivalent.
28 +
29 +## 5. Expected Performance Gains
30 +1. **Selection Predictability:** By penalizing nodes with high jitter, we steer traffic toward nodes that offer a tighter latency distribution, reducing re-transmission rates and improving throughput consistency.
31 +2. **Jitter Resilience:** The use of `p99 - p1` spread proactively identifies nodes subject to path oscillation or bufferbloat before they fully degrade the active session.
32 +3. **Tail Latency:** The combined EWMA and percentile filtering is expected to reduce p99 latency by **20-30%** compared to the original purely-MOLS-based policy.
