From 4fa16618733e1a5fff12620e0925ce2216f5a40d Mon Sep 17 00:00:00 2001 From: John Myers <9696606+johntmyers@users.noreply.github.com> Date: Sun, 15 Mar 2026 12:45:36 -0700 Subject: [PATCH 1/5] feat(sandbox): log connection attempts that bypass proxy path Add iptables LOG + REJECT rules inside the sandbox network namespace to detect and diagnose direct connection attempts that bypass the HTTP CONNECT proxy. This provides two improvements: 1. Fast-fail UX: applications get immediate ECONNREFUSED instead of a 30-second timeout when they bypass the proxy 2. Diagnostics: a /dev/kmsg monitor emits structured BYPASS_DETECT tracing events with destination, protocol, process identity, and actionable hints Both TCP and UDP bypass attempts are covered (UDP catches DNS bypass). The feature degrades gracefully if iptables or /dev/kmsg are unavailable.

Here is the full analysis: + +--- + +## Logging Configuration for `/var/log/openshell.log` in the OpenShell Sandbox Supervisor + +### Primary File: `crates/openshell-sandbox/src/main.rs` + +The entire logging setup lives in the `main()` function (lines 94-160). The sandbox supervisor configures a **dual-output tracing subscriber** with an optional third layer for gRPC log push. + +--- + +### 1. Log File Path + +The path `/var/log/openshell.log` is **hardcoded** on line 102 of `crates/openshell-sandbox/src/main.rs`. There are no constants, configuration values, or environment variables that control this path -- it is a literal string. + +```rust +// Lines 99-107 +let file_logging = std::fs::OpenOptions::new() + .create(true) + .append(true) + .open("/var/log/openshell.log") + .ok() + .map(|file| { + let (writer, guard) = tracing_appender::non_blocking(file); + (writer, guard) + }); +``` + +**Key details:** +- The file is opened with `create(true)` and `append(true)` -- it is created if it does not exist, and logs are appended (never truncated). +- The `.ok()` call converts any error into `None`, making the file open **non-fatal**. If `/var/log/openshell.log` cannot be opened (e.g., in custom container images where `/var/log` is not writable), the supervisor gracefully falls back to stdout-only logging and emits a warning on line 158. + +--- + +### 2. Tracing Subscriber Setup (Three Layers) + +The subscriber is built using `tracing_subscriber::registry()` with a layered architecture. There are **two code paths** depending on whether the log file was opened successfully. + +#### Path A: File logging available (lines 131-147) + +```rust +let _file_guard = if let Some((file_writer, file_guard)) = file_logging { + let file_filter = EnvFilter::new("info"); + tracing_subscriber::registry() + .with( + tracing_subscriber::fmt::layer() + .with_writer(std::io::stdout) + .with_filter(stdout_filter), + ) + .with( + tracing_subscriber::fmt::layer() + .with_writer(file_writer) + .with_ansi(false) + .with_filter(file_filter), + ) + .with(push_layer.clone()) + .init(); + Some(file_guard) +} +``` + +Three layers are registered on the `tracing_subscriber::Registry`: + +| Layer | Writer | Filter | ANSI | Notes | +|-------|--------|--------|------|-------| +| **stdout layer** | `std::io::stdout` | `stdout_filter` (see below) | Yes (default) | User-facing terminal output | +| **file layer** | `tracing_appender::non_blocking(file)` | `EnvFilter::new("info")` -- fixed at `info` | **No** (`.with_ansi(false)`) | Persistent log file | +| **log push layer** | gRPC channel (optional) | Internal `max_level` filter (default `INFO`) | N/A | Only present in gRPC mode | + +#### Path B: File logging unavailable (lines 148-160) + +```rust +else { + tracing_subscriber::registry() + .with( + tracing_subscriber::fmt::layer() + .with_writer(std::io::stdout) + .with_filter(stdout_filter), + ) + .with(push_layer) + .init(); + warn!("Could not open /var/log/openshell.log; using stdout-only logging"); + None +}; +``` + +Only two layers: stdout and the optional log push layer. The warning is emitted after the subscriber is initialized so it is actually visible. + +--- + +### 3. Filter Configuration + +**stdout filter** (line 109-110): +```rust +let stdout_filter = + EnvFilter::try_from_default_env().unwrap_or_else(|_| EnvFilter::new(&args.log_level)); +``` +- First tries the `RUST_LOG` environment variable (`try_from_default_env()`). +- Falls back to the `--log-level` CLI flag, which defaults to `"warn"` and is also settable via `OPENSHELL_LOG_LEVEL` (line 63-64). + +**file filter** (line 132): +```rust +let file_filter = EnvFilter::new("info"); +``` +- Hardcoded to `info` level. The file always captures `info`, `warn`, and `error` events regardless of the stdout level. + +**log push filter** (in `crates/openshell-sandbox/src/log_push.rs`, lines 31-34): +```rust +let max_level = std::env::var("OPENSHELL_LOG_PUSH_LEVEL") + .ok() + .and_then(|s| s.parse().ok()) + .unwrap_or(tracing::Level::INFO); +``` +- Defaults to `INFO`. Configurable via `OPENSHELL_LOG_PUSH_LEVEL` environment variable. +- Filtering is done manually in `on_event()` (line 48): `if *meta.level() > self.max_level { return; }` + +--- + +### 4. Non-Blocking Writer and Guard + +The file layer uses `tracing_appender::non_blocking()` (line 105) to wrap the `std::fs::File`: + +```rust +let (writer, guard) = tracing_appender::non_blocking(file); +``` + +- This creates a background I/O thread that handles writes asynchronously, so logging to the file never blocks the sandbox supervisor's async runtime. +- The `guard` (of type `tracing_appender::non_blocking::WorkerGuard`) is stored in `_file_guard` (line 131) and kept alive for the entire `main()` function. When the guard is dropped at process exit, it flushes any remaining buffered log lines to the file. + +--- + +### 5. Log Rotation and Formatting + +**No log rotation is configured.** The file is opened in append mode with `std::fs::OpenOptions`, not with `tracing_appender::rolling`. The `tracing-appender` crate's rolling file appender is available as a dependency (version `0.2` per workspace `Cargo.toml` line 59) but is not used. The log file grows unbounded for the lifetime of the sandbox process. + +**Formatting** uses the default `tracing_subscriber::fmt::layer()` formatter for both stdout and file layers. This is the `Full` format (the default when no `.fmt()` or `.event_format()` is called), which outputs lines like: + +``` +2026-03-13T10:00:00.000000Z INFO openshell_sandbox::proxy: CONNECT dst_host=example.com ... +``` + +The only formatting difference between the two layers: +- **stdout**: ANSI color codes enabled (default behavior). +- **file**: ANSI color codes explicitly disabled with `.with_ansi(false)` (line 142). + +--- + +### 6. Dependency Versions + +From `/Users/jomyers/code/OpenShell/Cargo.toml` (workspace root), lines 57-59: + +| Crate | Version | Features | +|-------|---------|----------| +| `tracing` | `0.1` | (default) | +| `tracing-subscriber` | `0.3` | `env-filter`, `json` | +| `tracing-appender` | `0.2` | (default) | + +The `openshell-sandbox` crate declares all three as workspace dependencies in its `Cargo.toml` (lines 63-65). + +--- + +### 7. Log Push Layer (Third Output Channel) + +In addition to stdout and the file, the sandbox can stream logs to the OpenShell gateway server via gRPC.

You can now continue with the user's answers in mind. +``` + +--- + +## Assistant (Plan · claude-opus-4-6 · 63.1s) + +_Thinking:_ + +The user wants: +1. **Structured call-site types** - Define Rust structs per OCSF class and emit them directly at call sites. This is the more invasive but higher-quality approach. +2. **Replace file layer format** - Switch `/var/log/openshell.log` to OCSF JSON. +3. **Serialize OCSF into gRPC** - Rather than big proto changes, just serialize the OCSF JSON and send it through the existing gRPC channel (presumably as a JSON string field in SandboxLogLine or a new field). + +This is a significant undertaking. + +Now I'm mapping out the full architecture: I'll need a new module with OCSF base event types and per-class structs for each event category, plus shared objects like Actor and NetworkEndpoint. Then I'll build a custom tracing layer that captures these structured events and writes them as OCSF JSON, with call sites using a new emit API to send events directly. + +For the migration, I'm going through all 98 log statements and categorizing them by OCSF class—starting with network activity events like proxy decisions and listening events that map to the Network Activity class with specific activity and action IDs. Looking at the HTTP activity decisions now, I see there are two main paths for FORWARD actions—one that denies requests based on the HTTP method and another that allows them, each mapping to different activity and action IDs. Now I'm mapping out the L7 request handling—these are the layer 7 protocol messages where activity and action IDs come from the HTTP method and the l7_decision logic, plus various failure cases like upstream response errors and policy denials that get categorized as "Other" or denied actions. + +Moving into SSH activity tracking, I see the server lifecycle from listening through connection attempts, with handshake verification failures also being tracked. Now I'm mapping out the process activity events—when processes launch, terminate, timeout, or fail to signal properly—and identifying the security-relevant findings like nonce replay attacks and unsafe disk policies. Looking at policy and configuration changes across those message ranges, Device Config State Change seems like the right category since it captures state shifts that affect security. But I'm realizing the operational errors like DNS failures and gRPC issues don't fit as cleanly—those would fall under Base Event as a catch-all for internal system issues that don't map to more specific OCSF categories. + +Now I'm reconsidering how to organize the actual log events themselves. Network Activity covers the L4 proxy decisions like CONNECT allows and denials, while HTTP Activity handles the L7 layer with FORWARD logs and request interception. SSH Activity captures the connection lifecycle, Process Activity tracks entrypoint processes from startup through termination, and Detection Finding covers security-relevant findings like nonce replays and policy validation issues. + +Then there's Application Lifecycle for supervisor and service state changes, Device Config State Change for policy and route configuration updates, and a catch-all Base Event category for operational events that don't fit elsewhere like gRPC failures and DNS resolution issues. + +For the implementation, I need to think about how to create compile-time types that map to these event classes. The approach would involve defining a crate or module that establishes the structured event types with proper categorization and validation. + +At the call sites, instead of unstructured logging, I'd emit strongly-typed event objects that capture all the relevant context—like network endpoints, action IDs, and severity levels—then serialize those to JSON through a custom tracing layer that writes to a channel. + +Now I'm thinking through how to integrate this with the existing gRPC and file logging infrastructure. The `SandboxLogLine` proto needs to carry the OCSF JSON somehow—either as a dedicated field, embedded in the message string, or structured in the fields HashMap. The cleanest approach is probably adding an optional `ocsf_json` field to the proto so consumers can distinguish OCSF events from traditional logs. + +I'm going to document this whole effort in a structured plan covering the OCSF version, the new crate, a complete mapping of all 98 events, how tracing integrates with both file and gRPC layers, a phased migration strategy, and testing approach. + +Good answers.

I counted 98 events in my first summary, but actually the agent counted 138 total (98 being the ones at INFO/WARN/ERROR that reach the file).

Looking back at my categorized breakdown, I need to verify the counts match up—I had numbered items going to 98 but some of those were DEBUG level events I shouldn't have included. Let me recount across the categories I identified: Lifecycle & Startup had 14, Policy Engine had 14, Policy Polling had 7, Inference Routing had 11, Network Proxy CONNECT had 13, and Network Proxy FORWARD had 8, which is already 67 before I finish the rest of the categories. + +Continuing through the remaining categories—Inference Interception with 7, SSH Server with 10, Process Management with 1, Network Namespace with 6, Platform Sandbox with 1, Denial Aggregator with 4, and Route Config Warnings with 2—that brings me to 98 total events. Since I'm excluding DEBUG-only entries that don't reach the file, I should proceed with mapping all 98 events to their corresponding OCSF classes, starting with Network Activity for the CONNECT proxy connections. continuing through the HTTP activity events, I'm seeing various proxy decision outcomes like parse errors, policy rejections, and successful forwards, along with inference interception and upstream connection handling—that brings the HTTP category to 16 events total.

The Device Config State Change category is particularly large, covering policy loading, inference routing configuration, and SSH connection management. I'm tracking all the specific failure modes and state transitions to understand the full event landscape. Defining the OCSF event structure... Building the event emission API... + +For the file layer, I'd implement a custom tracing subscriber that captures these events and serializes them as JSON lines to disk. + +Now I'm weighing the tradeoffs: keeping tracing macros with a custom OCSF-serializing layer gives us ecosystem benefits but loses compile-time schema validation, while bypassing tracing entirely for direct OCSF serialization gives us strict typing but sacrifices the flexibility of the tracing ecosystem. A hybrid approach where OCSF structs have an `.emit()` method that serializes to JSON and passes through tracing might give us the best of both worlds. + +Implementing the custom layer... + +Actually, I'm overcomplicating this. The cleaner approach is to have a dedicated `OcsfEmitter` that owns the file writer and handles OCSF events directly, bypassing the tracing infrastructure entirely. It can serialize events to JSON lines and write them to the file, while also pushing to the gRPC channel if needed. The tracing subscriber continues handling stdout output, but the file layer gets replaced with this simpler, more direct mechanism. + +This separation makes sense because OCSF events are a distinct typed system rather than being forced through the tracing framework. Debug-level tracing won't reach the file anyway since the filter is set to info level, so there's no conflict. The migration would involve creating an `openshell-ocsf` crate with the types and emitter, wiring it up in main alongside the existing tracing setup, then gradually converting log statements from tracing macros to direct OCSF event calls. + +For the gRPC side, I can keep it simple by adding an optional `ocsf_json` field to the `SandboxLogLine` proto—when it's populated, the gateway knows to treat it as OCSF-formatted data, while the existing fields stay for backwards compatibility.

The file layer\nis removed from the tracing subscriber and replaced by the OCSF emitter.\n\n### Call-site API\n\nBuilder pattern for ergonomics with compile-time class selection:\n\n```rust\nuse openshell_ocsf::prelude::*;\n\n// Network proxy CONNECT decision\nocsf.emit(\n NetworkActivity::open()\n .allowed()\n .severity_info()\n .src_endpoint(peer_addr.ip(), peer_addr.port())\n .dst_endpoint(&host_lc, port)\n .proxy_addr(local_addr)\n .actor_process(&binary_str, pid, &cmdline_str, &ancestors_str)\n .disposition_allowed()\n .policy_name(&policy_str)\n .message(\"CONNECT\")\n);\n\n// Process launched\nocsf.emit(\n ProcessActivity::launch()\n .severity_info()\n .process_pid(handle.pid())\n .process_cmd(&command)\n .status_success()\n .message(\"Process started\")\n);\n\n// Security detection\nocsf.emit(\n DetectionFinding::create()\n .severity_high()\n .finding_title(\"NSSH1 nonce replay detected\")\n .finding_desc(format!(\"Replayed nonce: {nonce}\"))\n .disposition_blocked()\n .message(\"NSSH1 nonce replay detected\")\n);\n```\n\nEach builder enforces required OCSF fields at compile time via typestate or\nmandatory constructor args. Optional fields use builder methods.\n\n### gRPC integration\n\nMinimal proto change to `SandboxLogLine`:\n\n```protobuf\nmessage SandboxLogLine {\n string sandbox_id = 1;\n int64 timestamp_ms = 2;\n string level = 3;\n string target = 4;\n string message = 5;\n string source = 6;\n map fields = 7;\n // NEW: When populated, contains the full OCSF JSON envelope.\n // Consumers should prefer this over the flat fields above.\n optional string ocsf_json = 8;\n}\n```\n\nThe `LogPushLayer` (or its replacement) receives the serialized JSON from the\nemitter channel and populates `ocsf_json`. The existing flat fields can be\npopulated for backward compatibility during migration, then deprecated.\n\n### Metadata object (common to all events)\n\nEvery OCSF event carries a `metadata` object:\n\n```json\n{\n \"metadata\": {\n \"version\": \"1.3.0\",\n \"product\": {\n \"name\": \"OpenShell Sandbox\",\n \"vendor_name\": \"OpenShell\",\n \"version\": \"\"\n },\n \"log_name\": \"openshell-sandbox\",\n \"log_provider\": \"openshell-ocsf\"\n }\n}\n```\n\nPopulated once at emitter init from build-time constants.\n\n---\n\n## Complete Event-to-OCSF Mapping\n\nAll 98 log events that reach `/var/log/openshell.log` (INFO/WARN/ERROR),\nmapped to OCSF classes. Events are grouped by target class.\n\n### Network Activity [4001] — 12 events\n\nL4 network connections through the CONNECT proxy.\nProfiles: Network Proxy, Security Control, Container.\n\n| # | Source | Current Message | activity_id | action_id | severity_id | disposition_id | Notes |\n|---|--------|----------------|-------------|-----------|-------------|----------------|-------|\n| 47 | proxy.rs:153 | `Proxy listening (tcp)` | 7 Listen | 1 Allowed | 1 Info | 16 No Action | Service ready |\n| 48 | proxy.rs:172 | `Proxy connection error` | 4 Fail | 0 Unknown | 3 Medium | 27 Error | |\n| 49 | proxy.rs:177 | `Proxy accept error` | 4 Fail | 0 Unknown | 3 Medium | 27 Error | |\n| 51 | proxy.rs:385 | `CONNECT` (allow) | 1 Open | 1 Allowed | 1 Info | 1 Allowed | Map `action` field; when deny: action_id=2 |\n| 51 | proxy.rs:385 | `CONNECT` (deny) | 1 Open | 2 Denied | 3 Medium | 2 Blocked | Same call site, branch on action field |\n| 52 | proxy.rs:431 | `CONNECT blocked: allowed_ips check failed` | 5 Refuse | 2 Denied | 3 Medium | 2 Blocked | SSRF protection |\n| 53 | proxy.rs:451 | `CONNECT blocked: invalid allowed_ips in policy` | 5 Refuse | 2 Denied | 3 Medium | 27 Error | Malformed policy |\n| 54 | proxy.rs:477 | `CONNECT blocked: internal address` | 5 Refuse | 2 Denied | 3 Medium | 2 Blocked | SSRF protection |\n| 55 | proxy.rs:504 | `Failed to clone OPA engine for L7` | 99 Other | 0 Unknown | 3 Medium | 27 Error | Operational degradation |\n| 56 | proxy.rs:562 | `TLS L7 relay error` | 4 Fail | 0 Unknown | 2 Low | 27 Error | |\n| 57 | proxy.rs:571 | `TLS termination not configured, falling back to L4` | 99 Other | 0 Unknown | 2 Low | 14 Delayed | Graceful degradation |\n| 58 | proxy.rs:589 | `Expected REST protocol but received non-matching bytes` | 5 Refuse | 2 Denied | 3 Medium | 2 Blocked | Protocol mismatch |\n| 59 | proxy.rs:617 | `L7 relay error` | 4 Fail | 0 Unknown | 2 Low | 27 Error | |\n\n**Field mapping:**\n- `src_endpoint` ← `src_addr`, `src_port`\n- `dst_endpoint` ← `dst_host`, `dst_port`\n- `proxy_endpoint` ← `proxy_addr`\n- `actor.process` ← `binary`, `binary_pid`, `cmdline`, `ancestors`\n- `firewall_rule.name` ← `policy`\n- `status_detail` ← `reason`\n\n---\n\n### HTTP Activity [4002] — 16 events\n\nL7 HTTP proxy decisions (FORWARD proxy, L7 inspection, inference interception).\nProfiles: Network Proxy, Security Control, Container.\n\n| #

Handles\n `class_uid`, `category_uid`, `type_uid`, `severity_id`, `time`, `time_dt`,\n `metadata`, `message`, and `unmapped`. Serializes to flat JSON via\n `#[serde(flatten)]`.\n\n2. **Shared objects** — Rust structs for `Metadata`, `Product`,\n `NetworkEndpoint`, `NetworkProxy`, `Actor`, `Process`, `FindingInfo`,\n `FirewallRule`, `AuthorizationResult`. Each derives `Serialize`.\n\n3. **Class body structs** — One per class (8 total). Required fields enforced\n by struct definition; optional fields are `Option`.\n\n4. **Builder API** — Each class exposes a builder that:\n - Takes required fields in the constructor\n - Provides chainable methods for optional fields\n - Produces a complete `OcsfEnvelope` via `.build()`\n\n5. **OcsfEmitter** — Owns the file writer and optional gRPC push sender.\n Exposes `emit(&self, event: E)`. Serializes to JSON,\n writes to file, sends to channel. Thread-safe (interior `Arc`).\n\n6. **Unit tests** — Validate JSON output against OCSF schema for each class.\n One test per class producing a sample event and asserting required field\n presence and correct `type_uid` calculation (`class_uid * 100 + activity_id`).\n\n### Phase 2: Wire up the emitter\n\n1. **main.rs changes:**\n - Remove the file layer from the tracing subscriber\n - Initialize `OcsfEmitter` with the `/var/log/openshell.log` file appender\n - Pass the emitter (or `Arc`) into `run_sandbox()` and subsystems\n - Keep stdout-only tracing subscriber for human output\n\n2. **LogPushLayer changes (log_push.rs):**\n - Receive OCSF JSON strings from the emitter's channel\n - Populate `ocsf_json` field on `SandboxLogLine`\n - Deprecate (but still populate) the flat `message`/`fields` for backward compat\n\n3. **Proto change:**\n - Add `optional string ocsf_json = 8` to `SandboxLogLine` in\n `proto/sandbox.proto`\n - Regenerate. No server-side changes needed initially — gateway stores and\n forwards.\n\n### Phase 3: Migrate call sites (by class, in order of impact)\n\nMigrate in this order — highest-volume, most security-relevant events first:\n\n| Order | Class | Events | Files to touch |\n|-------|-------|--------|----------------|\n| 1 | Network Activity [4001] | 12 | proxy.rs |\n| 2 | HTTP Activity [4002] | 16 | proxy.rs, l7/relay.rs |\n| 3 | SSH Activity [4007] | 9 | ssh.rs |\n| 4 | Detection Finding [2004] | 4 | lib.rs, opa.rs, ssh.rs |\n| 5 | Process Activity [1007] | 4 | lib.rs, process.rs |\n| 6 | Application Lifecycle [6002] | 6 | main.rs, lib.rs |\n| 7 | Device Config State Change [5019] | 35 | lib.rs, sandbox/mod.rs |\n| 8 | Base Event [0] | 12 | lib.rs, netns.rs, mechanistic_mapper.rs |\n\nEach migration:\n1. Replace `info!`/`warn!`/`error!` with `ocsf.emit(...)` call\n2. Remove the old tracing macro invocation\n3. If the same info also needs stdout visibility, emit a `tracing::debug!` with\n a one-line summary alongside the OCSF event (optional, for dev ergonomics)\n4. Update e2e tests that grep for the old message format\n\n### Phase 4: E2E test migration\n\nFiles affected: `e2e/python/test_sandbox_policy.py` (lines 170-180, 1546 and\nothers that read `/var/log/openshell.log`).\n\nTests currently `grep` for text patterns like `\"CONNECT\"` and\n`action=allow`. These need to be updated to parse JSON lines and assert on OCSF\nfield values:\n\n```python\nimport json\n\ndef parse_ocsf_log(log_path):\n events = []\n with open(log_path) as f:\n for line in f:\n events.append(json.loads(line))\n return events\n\ndef find_events(events, class_uid, **filters):\n return [e for e in events\n if e[\"class_uid\"] == class_uid\n and all(e.get(k) == v for k, v in filters.items())]\n\n# Example: find all denied CONNECT events\ndenied = find_events(events, 4001, action_id=2, activity_id=1)\n```\n\n### Phase 5: Deprecate flat log fields in gRPC\n\nOnce the gateway and any downstream consumers have adopted `ocsf_json`:\n1. Stop populating the flat `message`/`level`/`fields` on `SandboxLogLine`\n2. Mark them as deprecated in the proto\n3. Gateway can parse `ocsf_json` directly for storage/indexing\n\n---\n\n## Sample OCSF JSON Output\n\nWhat a CONNECT allow event looks like in `/var/log/openshell.log`:\n\n```json\n{\n \"class_uid\": 4001,\n \"class_name\": \"Network Activity\",\n \"category_uid\": 4,\n \"category_name\": \"Network Activity\",\n \"type_uid\": 400101,\n \"type_name\": \"Network Activity: Open\",\n \"activity_id\": 1,\n \"activity_name\": \"Open\",\n \"action_id\": 1,\n \"action\": \"Allowed\",\n \"severity_id\": 1,\n \"severity\": \"Informational\",\n \"disposition_id\": 1,\n \"disposition\": \"Allowed\",\n \"time\": 1741862400000,\n \"time_dt\": \"2026-03-13T12:00:00.000Z\",\n \"message\": \"CONNECT\",\n \"metadata\": {\n \"version\": \"1.3.0\",\n \"product\": {\n \"name\": \"OpenShell Sandbox\",\n \"vendor_name\": \"OpenShell\",\n \"version\": \"0.14.0\"\n },\n \"log_name\": \"openshell-sandbox\",\n \"log_provider\": \"openshell-ocsf\"\n },\n \"src_endpoint\": {\n \"ip\": \"10.42.1.5\",\n \"port\": 48230\n },\n \"dst_endpoint\": {\n \"ip\": \"api.github.com\",\n \"port\": 443\n },\n \"proxy_endpoint\": {\n \"ip\": \"127.0.0.1\",\n \"port\": 3128\n },\n \"actor\": {\n \"process\": {\n \"name\": \"curl\",\n \"pid\": 1234,\n \"cmd_line\": \"curl https://api.github.com/repos\",\n \"lineage\": [\"bash\", \"sh\", \"supervisor\"]\n }\n },\n \"firewall_rule\": {\n \"name\": \"default-allow-github\"\n },\n \"status_id\": 1,\n \"status\": \"Success\"\n}\n```\n\n---\n\n## Risks and Mitigations\n\n| Risk | Impact | Mitigation |\n|------|--------|------------|\n| JSON serialization overhead per event | Latency on hot proxy path | Benchmark. The CONNECT/FORWARD/L7_REQUEST paths are the most frequent. Pre-allocate buffers in the emitter. If needed, use `simd-json` or `serde_json::to_writer` directly to the non-blocking appender. |\n| Log file size increase (JSON >> text) | Disk pressure in long-lived sandboxes | JSON is ~2-3x larger than fmt::Full.

The user's question is whether the `openshell-ocsf` crate can be shared between the sandbox (producer), CLI (consumer), and TUI (consumer) to provide nice human-readable formatting. + +Key findings: +1. CLI uses `print_log_line()` in `run.rs:3954-3984` - simple text format +2. TUI uses `render_log_line()` in `sandbox_logs.rs:230-265` - smart field ordering, color coding +3. Both consume `SandboxLogLine` proto from the gateway +4. The TUI already has custom "smart ordering" for CONNECT and L7_REQUEST fields + + +5. The solution is to have `openshell-ocsf` handle both serialization in the sandbox and deserialization plus formatting in the CLI and TUI, eliminating the need for custom rendering logic in each consumer. + +This works really well. The data flow is clean -- the gateway is already a passthrough for `SandboxLogLine`, and both the CLI and TUI already have their own formatting layers. Here's how `openshell-ocsf` as a shared crate eliminates the duplication and gives you typed rendering. + +## Current state + +Both consumers format logs independently with ad-hoc logic: + +**CLI** (`run.rs:3954-3984`) -- flat text, alphabetical fields: +``` +[1700000000.456] [sandbox] [INFO ] [openshell_sandbox::proxy] CONNECT action=allow dst_host=example.com dst_port=443 ... +``` + +**TUI** (`sandbox_logs.rs:230-265`) -- hardcoded "smart ordering" for known message types: +``` +12:00:01 sandbox INFO CONNECT action=allow dst_host=example.com dst_port=443 policy=my-policy ... +``` + +The TUI has a hand-maintained `ordered_fields()` function (`sandbox_logs.rs:351-391`) that special-cases `"CONNECT"` and `"L7_REQUEST"` messages to order fields by importance. Everything else falls back to alphabetical. This is the exact kind of thing that should live on the type. + +## How `openshell-ocsf` as a shared crate changes this + +The crate serves three roles depending on who imports it: + +``` +crates/openshell-ocsf/ + src/ + lib.rs + ... + display.rs # Human-readable formatting (NEW) + display/ + network_activity.rs + http_activity.rs + ssh_activity.rs + process_activity.rs + detection_finding.rs + application_lifecycle.rs + config_state_change.rs + base_event.rs +``` + +### Dependency graph + +``` +openshell-ocsf (shared: types + serialize + deserialize + display) + ^ ^ ^ + | | | +openshell-sandbox openshell-cli openshell-tui +(emit events) (parse + render) (parse + render) +``` + +The gateway (`openshell-server`) does NOT need to depend on this crate at all.

You can now continue with the user's answers in mind. +``` + +--- + +## Assistant (Plan · claude-opus-4-6 · 12.7s) + +Good calls. Let me summarize the resolved decisions: + +**Log rotation:** Size-based via `tracing-appender::rolling` with a max file size (50MB). This is the `max_log_files` + size-based rolling feature in `tracing-appender`. The `OcsfEmitter` will use this instead of raw `OpenOptions::append`. One thing to note -- `tracing-appender` 0.2 has `RollingFileAppender` with time-based rotation built in, but size-based requires the `rolling` feature with a custom trigger or upgrading to the newer API. We may need to evaluate whether `tracing-appender` 0.2's API is sufficient or if we roll our own simple size check on write. I'll note that in the plan as a spike item. + +**OCSF validation:** Unit tests per class + vendored OCSF 1.3.0 JSON schema in the repo. The `jsonschema` crate validates sample output against it. This catches field naming/typing errors at test time without any CI network dependency. The schema files go under something like `crates/openshell-ocsf/schema/1.3.0/`. + +**Unmapped policy:** Preserve all current fields. Every tracing field that exists today goes into `unmapped` for Base Event [0] events. No information loss. For the typed classes (Network Activity, HTTP Activity, etc.), fields that map to OCSF attributes go to their proper location, and anything domain-specific that doesn't fit goes into `unmapped` (e.g., `l7_protocol`, `inference_kind`). + +All three questions are resolved.

Here is the full analysis: - ---- - -## Logging Configuration for `/var/log/openshell.log` in the OpenShell Sandbox Supervisor - -### Primary File: `crates/openshell-sandbox/src/main.rs` - -The entire logging setup lives in the `main()` function (lines 94-160). The sandbox supervisor configures a **dual-output tracing subscriber** with an optional third layer for gRPC log push. - ---- - -### 1. Log File Path - -The path `/var/log/openshell.log` is **hardcoded** on line 102 of `crates/openshell-sandbox/src/main.rs`. There are no constants, configuration values, or environment variables that control this path -- it is a literal string. - -```rust -// Lines 99-107 -let file_logging = std::fs::OpenOptions::new() - .create(true) - .append(true) - .open("/var/log/openshell.log") - .ok() - .map(|file| { - let (writer, guard) = tracing_appender::non_blocking(file); - (writer, guard) - }); -``` - -**Key details:** -- The file is opened with `create(true)` and `append(true)` -- it is created if it does not exist, and logs are appended (never truncated). -- The `.ok()` call converts any error into `None`, making the file open **non-fatal**. If `/var/log/openshell.log` cannot be opened (e.g., in custom container images where `/var/log` is not writable), the supervisor gracefully falls back to stdout-only logging and emits a warning on line 158. - ---- - -### 2. Tracing Subscriber Setup (Three Layers) - -The subscriber is built using `tracing_subscriber::registry()` with a layered architecture. There are **two code paths** depending on whether the log file was opened successfully. - -#### Path A: File logging available (lines 131-147) - -```rust -let _file_guard = if let Some((file_writer, file_guard)) = file_logging { - let file_filter = EnvFilter::new("info"); - tracing_subscriber::registry() - .with( - tracing_subscriber::fmt::layer() - .with_writer(std::io::stdout) - .with_filter(stdout_filter), - ) - .with( - tracing_subscriber::fmt::layer() - .with_writer(file_writer) - .with_ansi(false) - .with_filter(file_filter), - ) - .with(push_layer.clone()) - .init(); - Some(file_guard) -} -``` - -Three layers are registered on the `tracing_subscriber::Registry`: - -| Layer | Writer | Filter | ANSI | Notes | -|-------|--------|--------|------|-------| -| **stdout layer** | `std::io::stdout` | `stdout_filter` (see below) | Yes (default) | User-facing terminal output | -| **file layer** | `tracing_appender::non_blocking(file)` | `EnvFilter::new("info")` -- fixed at `info` | **No** (`.with_ansi(false)`) | Persistent log file | -| **log push layer** | gRPC channel (optional) | Internal `max_level` filter (default `INFO`) | N/A | Only present in gRPC mode | - -#### Path B: File logging unavailable (lines 148-160) - -```rust -else { - tracing_subscriber::registry() - .with( - tracing_subscriber::fmt::layer() - .with_writer(std::io::stdout) - .with_filter(stdout_filter), - ) - .with(push_layer) - .init(); - warn!("Could not open /var/log/openshell.log; using stdout-only logging"); - None -}; -``` - -Only two layers: stdout and the optional log push layer. The warning is emitted after the subscriber is initialized so it is actually visible. - ---- - -### 3. Filter Configuration - -**stdout filter** (line 109-110): -```rust -let stdout_filter = - EnvFilter::try_from_default_env().unwrap_or_else(|_| EnvFilter::new(&args.log_level)); -``` -- First tries the `RUST_LOG` environment variable (`try_from_default_env()`). -- Falls back to the `--log-level` CLI flag, which defaults to `"warn"` and is also settable via `OPENSHELL_LOG_LEVEL` (line 63-64). - -**file filter** (line 132): -```rust -let file_filter = EnvFilter::new("info"); -``` -- Hardcoded to `info` level. The file always captures `info`, `warn`, and `error` events regardless of the stdout level. - -**log push filter** (in `crates/openshell-sandbox/src/log_push.rs`, lines 31-34): -```rust -let max_level = std::env::var("OPENSHELL_LOG_PUSH_LEVEL") - .ok() - .and_then(|s| s.parse().ok()) - .unwrap_or(tracing::Level::INFO); -``` -- Defaults to `INFO`. Configurable via `OPENSHELL_LOG_PUSH_LEVEL` environment variable. -- Filtering is done manually in `on_event()` (line 48): `if *meta.level() > self.max_level { return; }` - ---- - -### 4. Non-Blocking Writer and Guard - -The file layer uses `tracing_appender::non_blocking()` (line 105) to wrap the `std::fs::File`: - -```rust -let (writer, guard) = tracing_appender::non_blocking(file); -``` - -- This creates a background I/O thread that handles writes asynchronously, so logging to the file never blocks the sandbox supervisor's async runtime. -- The `guard` (of type `tracing_appender::non_blocking::WorkerGuard`) is stored in `_file_guard` (line 131) and kept alive for the entire `main()` function. When the guard is dropped at process exit, it flushes any remaining buffered log lines to the file. - ---- - -### 5. Log Rotation and Formatting - -**No log rotation is configured.** The file is opened in append mode with `std::fs::OpenOptions`, not with `tracing_appender::rolling`. The `tracing-appender` crate's rolling file appender is available as a dependency (version `0.2` per workspace `Cargo.toml` line 59) but is not used. The log file grows unbounded for the lifetime of the sandbox process. - -**Formatting** uses the default `tracing_subscriber::fmt::layer()` formatter for both stdout and file layers. This is the `Full` format (the default when no `.fmt()` or `.event_format()` is called), which outputs lines like: - -``` -2026-03-13T10:00:00.000000Z INFO openshell_sandbox::proxy: CONNECT dst_host=example.com ... -``` - -The only formatting difference between the two layers: -- **stdout**: ANSI color codes enabled (default behavior). -- **file**: ANSI color codes explicitly disabled with `.with_ansi(false)` (line 142). - ---- - -### 6. Dependency Versions - -From `/Users/jomyers/code/OpenShell/Cargo.toml` (workspace root), lines 57-59: - -| Crate | Version | Features | -|-------|---------|----------| -| `tracing` | `0.1` | (default) | -| `tracing-subscriber` | `0.3` | `env-filter`, `json` | -| `tracing-appender` | `0.2` | (default) | - -The `openshell-sandbox` crate declares all three as workspace dependencies in its `Cargo.toml` (lines 63-65). - ---- - -### 7. Log Push Layer (Third Output Channel) - -In addition to stdout and the file, the sandbox can stream logs to the OpenShell gateway server via gRPC. This is set up in lines 116-127 of `main.rs` and implemented in `/Users/jomyers/code/OpenShell/crates/openshell-sandbox/src/log_push.rs`. - -**Activation condition** (lines 116-118): Only enabled when both `--sandbox-id` and `--openshell-endpoint` are provided (gRPC mode). - -**Key characteristics:** -- Uses a bounded `mpsc::channel(1024)` (log_push.rs line 81) between the tracing layer and a background Tokio task. -- Events are sent via `try_send()` (line 68) -- never blocks; drops events if the channel is full. -- The background task batches up to 50 lines (line 98) and flushes either when the batch is full or every 500ms (line 160). -- On gRPC connection failure, it retries with exponential backoff from 1s to 30s max (lines 89-91), draining and buffering up to 200 lines during backoff (line 225). -- Each `SandboxLogLine` includes: `sandbox_id`, `timestamp_ms`, `level`, `target`, `message`, `source` ("sandbox"), and structured `fields` (HashMap). - ---- - -### 8.

Identity validation | 1 | `Validated 'sandbox' user exists in image` (#45) | - -### Key observations for OCSF adoption: - -1. **The `CONNECT`, `FORWARD`, and `L7_REQUEST` logs are the most OCSF-ready.** They already carry rich structured fields (`src_addr`, `dst_host`, `dst_port`, `action`, `reason`, `policy`, `binary`, `pid`, `cmdline`) that map almost directly to OCSF Network Activity and Web Resource Access Activity schemas. - -2. **Most logs are unstructured messages with ad-hoc fields.** There's no consistent schema across log events -- field names vary (e.g., `error` vs `error = %e`, `host` vs `dst_host`), and many events lack fields that OCSF would require (like `activity_id`, `category_uid`, `class_uid`, `severity_id`, `time`). - -3. **No event classification metadata exists today.** Nothing identifies log type, category, or severity in a machine-readable way beyond the tracing level. - -4. **The `tracing-subscriber` already has the `json` feature enabled** in `Cargo.toml` but it's not used for the file layer. Switching to `.json()` on the file layer formatter would be a minimal change that gives structured output suitable for OCSF transformation. - -Want me to draft a plan for adopting OCSF formatting for these log events? - ---- - -## User - -What are the Structured Fields column values? - ---- - -## Assistant (Plan · claude-opus-4-6 · 9.0s) - -_Thinking:_ - -The user is asking about the "Structured Fields" column in my log inventory tables.

You can now continue with the user's answers in mind. -``` - ---- - -## Assistant (Plan · claude-opus-4-6 · 63.1s) - -_Thinking:_ - -The user wants: -1. **Structured call-site types** - Define Rust structs per OCSF class and emit them directly at call sites. This is the more invasive but higher-quality approach. -2. **Replace file layer format** - Switch `/var/log/openshell.log` to OCSF JSON. -3. **Serialize OCSF into gRPC** - Rather than big proto changes, just serialize the OCSF JSON and send it through the existing gRPC channel (presumably as a JSON string field in SandboxLogLine or a new field). - -This is a significant undertaking. - -Now I'm mapping out the full architecture: I'll need a new module with OCSF base event types and per-class structs for each event category, plus shared objects like Actor and NetworkEndpoint. Then I'll build a custom tracing layer that captures these structured events and writes them as OCSF JSON, with call sites using a new emit API to send events directly. - -For the migration, I'm going through all 98 log statements and categorizing them by OCSF class—starting with network activity events like proxy decisions and listening events that map to the Network Activity class with specific activity and action IDs. Looking at the HTTP activity decisions now, I see there are two main paths for FORWARD actions—one that denies requests based on the HTTP method and another that allows them, each mapping to different activity and action IDs. Now I'm mapping out the L7 request handling—these are the layer 7 protocol messages where activity and action IDs come from the HTTP method and the l7_decision logic, plus various failure cases like upstream response errors and policy denials that get categorized as "Other" or denied actions. - -Moving into SSH activity tracking, I see the server lifecycle from listening through connection attempts, with handshake verification failures also being tracked. Now I'm mapping out the process activity events—when processes launch, terminate, timeout, or fail to signal properly—and identifying the security-relevant findings like nonce replay attacks and unsafe disk policies. Looking at policy and configuration changes across those message ranges, Device Config State Change seems like the right category since it captures state shifts that affect security. But I'm realizing the operational errors like DNS failures and gRPC issues don't fit as cleanly—those would fall under Base Event as a catch-all for internal system issues that don't map to more specific OCSF categories. - -Now I'm reconsidering how to organize the actual log events themselves. Network Activity covers the L4 proxy decisions like CONNECT allows and denials, while HTTP Activity handles the L7 layer with FORWARD logs and request interception. SSH Activity captures the connection lifecycle, Process Activity tracks entrypoint processes from startup through termination, and Detection Finding covers security-relevant findings like nonce replays and policy validation issues. - -Then there's Application Lifecycle for supervisor and service state changes, Device Config State Change for policy and route configuration updates, and a catch-all Base Event category for operational events that don't fit elsewhere like gRPC failures and DNS resolution issues. - -For the implementation, I need to think about how to create compile-time types that map to these event classes. The approach would involve defining a crate or module that establishes the structured event types with proper categorization and validation. - -At the call sites, instead of unstructured logging, I'd emit strongly-typed event objects that capture all the relevant context—like network endpoints, action IDs, and severity levels—then serialize those to JSON through a custom tracing layer that writes to a channel. - -Now I'm thinking through how to integrate this with the existing gRPC and file logging infrastructure. The `SandboxLogLine` proto needs to carry the OCSF JSON somehow—either as a dedicated field, embedded in the message string, or structured in the fields HashMap. The cleanest approach is probably adding an optional `ocsf_json` field to the proto so consumers can distinguish OCSF events from traditional logs. - -I'm going to document this whole effort in a structured plan covering the OCSF version, the new crate, a complete mapping of all 98 events, how tracing integrates with both file and gRPC layers, a phased migration strategy, and testing approach. - -Good answers. Structured types at pre-release is the right call, and serializing OCSF JSON into the existing gRPC channel avoids proto churn.

Since I'm excluding DEBUG-only entries that don't reach the file, I should proceed with mapping all 98 events to their corresponding OCSF classes, starting with Network Activity for the CONNECT proxy connections. continuing through the HTTP activity events, I'm seeing various proxy decision outcomes like parse errors, policy rejections, and successful forwards, along with inference interception and upstream connection handling—that brings the HTTP category to 16 events total.

The Device Config State Change category is particularly large, covering policy loading, inference routing configuration, and SSH connection management. I'm tracking all the specific failure modes and state transitions to understand the full event landscape. Defining the OCSF event structure... Building the event emission API... - -For the file layer, I'd implement a custom tracing subscriber that captures these events and serializes them as JSON lines to disk. - -Now I'm weighing the tradeoffs: keeping tracing macros with a custom OCSF-serializing layer gives us ecosystem benefits but loses compile-time schema validation, while bypassing tracing entirely for direct OCSF serialization gives us strict typing but sacrifices the flexibility of the tracing ecosystem. A hybrid approach where OCSF structs have an `.emit()` method that serializes to JSON and passes through tracing might give us the best of both worlds. - -Implementing the custom layer... - -Actually, I'm overcomplicating this. The cleaner approach is to have a dedicated `OcsfEmitter` that owns the file writer and handles OCSF events directly, bypassing the tracing infrastructure entirely. It can serialize events to JSON lines and write them to the file, while also pushing to the gRPC channel if needed. The tracing subscriber continues handling stdout output, but the file layer gets replaced with this simpler, more direct mechanism. - -This separation makes sense because OCSF events are a distinct typed system rather than being forced through the tracing framework. Debug-level tracing won't reach the file anyway since the filter is set to info level, so there's no conflict. The migration would involve creating an `openshell-ocsf` crate with the types and emitter, wiring it up in main alongside the existing tracing setup, then gradually converting log statements from tracing macros to direct OCSF event calls. - -For the gRPC side, I can keep it simple by adding an optional `ocsf_json` field to the `SandboxLogLine` proto—when it's populated, the gateway knows to treat it as OCSF-formatted data, while the existing fields stay for backwards compatibility. Now I'll write out the detailed migration plan with the full struct hierarchy and event mappings. - -**Tool: todowrite** - -**Input:** -```json -{ - "todos": [ - { - "content": "Research OCSF schema details (classes, profiles, base event)", - "status": "completed", - "priority": "high" - }, - { - "content": "Catalog all sandbox supervisor log statements", - "status": "completed", - "priority": "high" - }, - { - "content": "Map all 98 log events to OCSF classes", - "status": "completed", - "priority": "high" - }, - { - "content": "Write comprehensive OCSF adoption plan to architecture/plans/", - "status": "in_progress", - "priority": "high" - } - ] -} -``` - -**Output:** -``` -[ - { - "content": "Research OCSF schema details (classes, profiles, base event)", - "status": "completed", - "priority": "high" - }, - { - "content": "Catalog all sandbox supervisor log statements", - "status": "completed", - "priority": "high" - }, - { - "content": "Map all 98 log events to OCSF classes", - "status": "completed", - "priority": "high" - }, - { - "content": "Write comprehensive OCSF adoption plan to architecture/plans/", - "status": "in_progress", - "priority": "high" - } -] -``` - ---- - -## Assistant (Plan · claude-opus-4-6 · 162.7s) - -**Tool: write** - -**Input:** -```json -{ - "filePath": "/Users/jomyers/code/OpenShell/architecture/plans/ocsf-adoption.md", - "content": "# OCSF Adoption for Sandbox Supervisor Logging\n\n## Problem Statement\n\nThe sandbox supervisor emits 98 log events (INFO/WARN/ERROR) to\n`/var/log/openshell.log` using ad-hoc tracing fields with no consistent schema.\nField names vary (`error` vs `host` vs `dst_host`), there is no event\nclassification metadata, and consumers (gateway log push, e2e tests, support\ndebugging) must pattern-match free-form text.\n\nWe want to adopt OCSF v1.3.0 (Open Cybersecurity Schema Framework) as the\nstructured logging standard for all events written to the file and pushed to the\ngateway. This gives us machine-readable, vendor-neutral security telemetry from\nthe sandbox.\n\n## Design Decisions\n\n| Decision | Choice | Rationale |\n|----------|--------|-----------|\n| OCSF version | **1.3.0** | Latest stable. Has SSH Activity [4007] and Detection Finding [2004]. |\n| Emission strategy | **Structured call-site types** | Pre-release — invest in compile-time schema correctness now. |\n| File layer format | **Replace fmt::Full with OCSF JSON lines** | Single format, clean break. No dual-file overhead. |\n| gRPC log push | **Serialize OCSF JSON into existing proto** | Add `ocsf_json: optional string` to `SandboxLogLine`. Avoids massive proto restructuring. |\n| stdout | **Keep fmt::Full for humans** | Developers need readable terminal output. Unchanged. |\n| OCSF profiles | **Container, Network Proxy, Security Control, Host** | Match our domain: sandboxed containers behind a network proxy with policy enforcement. |\n\n## Architecture\n\n### New crate: `openshell-ocsf`\n\nA workspace crate under `crates/openshell-ocsf/` containing:\n\n```\ncrates/openshell-ocsf/\n├── src/\n│ ├── lib.rs # Public API: emit(), OcsfEmitter\n│ ├── envelope.rs # Base event envelope (common fields)\n│ ├── classes/\n│ │ ├── mod.rs\n│ │ ├── network_activity.rs # [4001]\n│ │ ├── http_activity.rs # [4002]\n│ │ ├── ssh_activity.rs # [4007]\n│ │ ├── process_activity.rs # [1007]\n│ │ ├── detection_finding.rs # [2004]\n│ │ ├── application_lifecycle.rs # [6002]\n│ │ ├── config_state_change.rs # [5019]\n│ │ └── base_event.rs # [0]\n│ ├── objects/\n│ │ ├── mod.rs\n│ │ ├── metadata.rs # Metadata object\n│ │ ├── product.rs # Product object\n│ │ ├── network_endpoint.rs\n│ │ ├── network_proxy.rs\n│ │ ├── actor.rs # Actor (process attribution)\n│ │ ├── process.rs # Process object\n│ │ ├── finding_info.rs # Finding info for Detection Finding\n│ │ ├── firewall_rule.rs # Policy rule reference\n│ │ └── authorization.rs # Authorization result\n│ └── emitter.rs # OcsfEmitter: file writer + channel\n```\n\nDependencies: `serde`, `serde_json`, `tracing-appender` (non-blocking writer),\n`tokio::sync::mpsc` (for gRPC push channel).\n\n### Emission flow\n\n```\nCall site OcsfEmitter\n │ │\n │ ocsf::emit(event) │\n ├───────────────────────────>│\n │ ├──> serialize to JSON line\n │ ├──> write to /var/log/openshell.log (non-blocking)\n │ └──> send JSON to gRPC push channel (try_send)\n```\n\nThe `OcsfEmitter` is initialized in `main.rs` alongside the tracing subscriber.\nIt owns:\n1. The `tracing_appender::non_blocking::NonBlocking` writer for the file\n2. A `tokio::sync::mpsc::Sender` for the gRPC log push task\n\nThe existing tracing subscriber retains the **stdout layer only**. The file layer\nis removed from the tracing subscriber and replaced by the OCSF emitter.\n\n### Call-site API\n\nBuilder pattern for ergonomics with compile-time class selection:\n\n```rust\nuse openshell_ocsf::prelude::*;\n\n// Network proxy CONNECT decision\nocsf.emit(\n NetworkActivity::open()\n .allowed()\n .severity_info()\n .src_endpoint(peer_addr.ip(), peer_addr.port())\n .dst_endpoint(&host_lc, port)\n .proxy_addr(local_addr)\n .actor_process(&binary_str, pid, &cmdline_str, &ancestors_str)\n .disposition_allowed()\n .policy_name(&policy_str)\n .message(\"CONNECT\")\n);\n\n// Process launched\nocsf.emit(\n ProcessActivity::launch()\n .severity_info()\n .process_pid(handle.pid())\n .process_cmd(&command)\n .status_success()\n .message(\"Process started\")\n);\n\n// Security detection\nocsf.emit(\n DetectionFinding::create()\n .severity_high()\n .finding_title(\"NSSH1 nonce replay detected\")\n .finding_desc(format!(\"Replayed nonce: {nonce}\"))\n .disposition_blocked()\n .message(\"NSSH1 nonce replay detected\")\n);\n```\n\nEach builder enforces required OCSF fields at compile time via typestate or\nmandatory constructor args. Optional fields use builder methods.\n\n### gRPC integration\n\nMinimal proto change to `SandboxLogLine`:\n\n```protobuf\nmessage SandboxLogLine {\n string sandbox_id = 1;\n int64 timestamp_ms = 2;\n string level = 3;\n string target = 4;\n string message = 5;\n string source = 6;\n map fields = 7;\n // NEW: When populated, contains the full OCSF JSON envelope.\n // Consumers should prefer this over the flat fields above.\n optional string ocsf_json = 8;\n}\n```\n\nThe `LogPushLayer` (or its replacement) receives the serialized JSON from the\nemitter channel and populates `ocsf_json`. The existing flat fields can be\npopulated for backward compatibility during migration, then deprecated.\n\n### Metadata object (common to all events)\n\nEvery OCSF event carries a `metadata` object:\n\n```json\n{\n \"metadata\": {\n \"version\": \"1.3.0\",\n \"product\": {\n \"name\": \"OpenShell Sandbox\",\n \"vendor_name\": \"OpenShell\",\n \"version\": \"\"\n },\n \"log_name\": \"openshell-sandbox\",\n \"log_provider\": \"openshell-ocsf\"\n }\n}\n```\n\nPopulated once at emitter init from build-time constants.\n\n---\n\n## Complete Event-to-OCSF Mapping\n\nAll 98 log events that reach `/var/log/openshell.log` (INFO/WARN/ERROR),\nmapped to OCSF classes. Events are grouped by target class.\n\n### Network Activity [4001] — 12 events\n\nL4 network connections through the CONNECT proxy.\nProfiles: Network Proxy, Security Control, Container.\n\n| # | Source | Current Message | activity_id | action_id | severity_id | disposition_id | Notes |\n|---|--------|----------------|-------------|-----------|-------------|----------------|-------|\n| 47 | proxy.rs:153 | `Proxy listening (tcp)` | 7 Listen | 1 Allowed | 1 Info | 16 No Action | Service ready |\n| 48 | proxy.rs:172 | `Proxy connection error` | 4 Fail | 0 Unknown | 3 Medium | 27 Error | |\n| 49 | proxy.rs:177 | `Proxy accept error` | 4 Fail | 0 Unknown | 3 Medium | 27 Error | |\n| 51 | proxy.rs:385 | `CONNECT` (allow) | 1 Open | 1 Allowed | 1 Info | 1 Allowed | Map `action` field; when deny: action_id=2 |\n| 51 | proxy.rs:385 | `CONNECT` (deny) | 1 Open | 2 Denied | 3 Medium | 2 Blocked | Same call site, branch on action field |\n| 52 | proxy.rs:431 | `CONNECT blocked: allowed_ips check failed` | 5 Refuse | 2 Denied | 3 Medium | 2 Blocked | SSRF protection |\n| 53 | proxy.rs:451 | `CONNECT blocked: invalid allowed_ips in policy` | 5 Refuse | 2 Denied | 3 Medium | 27 Error | Malformed policy |\n| 54 | proxy.rs:477 | `CONNECT blocked: internal address` | 5 Refuse | 2 Denied | 3 Medium | 2 Blocked | SSRF protection |\n| 55 | proxy.rs:504 | `Failed to clone OPA engine for L7` | 99 Other | 0 Unknown | 3 Medium | 27 Error | Operational degradation |\n| 56 | proxy.rs:562 | `TLS L7 relay error` | 4 Fail | 0 Unknown | 2 Low | 27 Error | |\n| 57 | proxy.rs:571 | `TLS termination not configured, falling back to L4` | 99 Other | 0 Unknown | 2 Low | 14 Delayed | Graceful degradation |\n| 58 | proxy.rs:589 | `Expected REST protocol but received non-matching bytes` | 5 Refuse | 2 Denied | 3 Medium | 2 Blocked | Protocol mismatch |\n| 59 | proxy.rs:617 | `L7 relay error` | 4 Fail | 0 Unknown | 2 Low | 27 Error | |\n\n**Field mapping:**\n- `src_endpoint` ← `src_addr`, `src_port`\n- `dst_endpoint` ← `dst_host`, `dst_port`\n- `proxy_endpoint` ← `proxy_addr`\n- `actor.process` ← `binary`, `binary_pid`, `cmdline`, `ancestors`\n- `firewall_rule.name` ← `policy`\n- `status_detail` ← `reason`\n\n---\n\n### HTTP Activity [4002] — 16 events\n\nL7 HTTP proxy decisions (FORWARD proxy, L7 inspection, inference interception).\nProfiles: Network Proxy, Security Control, Container.\n\n| #

Handles\n `class_uid`, `category_uid`, `type_uid`, `severity_id`, `time`, `time_dt`,\n `metadata`, `message`, and `unmapped`. Serializes to flat JSON via\n `#[serde(flatten)]`.\n\n2. **Shared objects** — Rust structs for `Metadata`, `Product`,\n `NetworkEndpoint`, `NetworkProxy`, `Actor`, `Process`, `FindingInfo`,\n `FirewallRule`, `AuthorizationResult`. Each derives `Serialize`.\n\n3. **Class body structs** — One per class (8 total). Required fields enforced\n by struct definition; optional fields are `Option`.\n\n4. **Builder API** — Each class exposes a builder that:\n - Takes required fields in the constructor\n - Provides chainable methods for optional fields\n - Produces a complete `OcsfEnvelope` via `.build()`\n\n5. **OcsfEmitter** — Owns the file writer and optional gRPC push sender.\n Exposes `emit(&self, event: E)`. Serializes to JSON,\n writes to file, sends to channel. Thread-safe (interior `Arc`).\n\n6. **Unit tests** — Validate JSON output against OCSF schema for each class.\n One test per class producing a sample event and asserting required field\n presence and correct `type_uid` calculation (`class_uid * 100 + activity_id`).\n\n### Phase 2: Wire up the emitter\n\n1. **main.rs changes:**\n - Remove the file layer from the tracing subscriber\n - Initialize `OcsfEmitter` with the `/var/log/openshell.log` file appender\n - Pass the emitter (or `Arc`) into `run_sandbox()` and subsystems\n - Keep stdout-only tracing subscriber for human output\n\n2. **LogPushLayer changes (log_push.rs):**\n - Receive OCSF JSON strings from the emitter's channel\n - Populate `ocsf_json` field on `SandboxLogLine`\n - Deprecate (but still populate) the flat `message`/`fields` for backward compat\n\n3. **Proto change:**\n - Add `optional string ocsf_json = 8` to `SandboxLogLine` in\n `proto/sandbox.proto`\n - Regenerate. No server-side changes needed initially — gateway stores and\n forwards.\n\n### Phase 3: Migrate call sites (by class, in order of impact)\n\nMigrate in this order — highest-volume, most security-relevant events first:\n\n| Order | Class | Events | Files to touch |\n|-------|-------|--------|----------------|\n| 1 | Network Activity [4001] | 12 | proxy.rs |\n| 2 | HTTP Activity [4002] | 16 | proxy.rs, l7/relay.rs |\n| 3 | SSH Activity [4007] | 9 | ssh.rs |\n| 4 | Detection Finding [2004] | 4 | lib.rs, opa.rs, ssh.rs |\n| 5 | Process Activity [1007] | 4 | lib.rs, process.rs |\n| 6 | Application Lifecycle [6002] | 6 | main.rs, lib.rs |\n| 7 | Device Config State Change [5019] | 35 | lib.rs, sandbox/mod.rs |\n| 8 | Base Event [0] | 12 | lib.rs, netns.rs, mechanistic_mapper.rs |\n\nEach migration:\n1. Replace `info!`/`warn!`/`error!` with `ocsf.emit(...)` call\n2. Remove the old tracing macro invocation\n3. If the same info also needs stdout visibility, emit a `tracing::debug!` with\n a one-line summary alongside the OCSF event (optional, for dev ergonomics)\n4. Update e2e tests that grep for the old message format\n\n### Phase 4: E2E test migration\n\nFiles affected: `e2e/python/test_sandbox_policy.py` (lines 170-180, 1546 and\nothers that read `/var/log/openshell.log`).\n\nTests currently `grep` for text patterns like `\"CONNECT\"` and\n`action=allow`. These need to be updated to parse JSON lines and assert on OCSF\nfield values:\n\n```python\nimport json\n\ndef parse_ocsf_log(log_path):\n events = []\n with open(log_path) as f:\n for line in f:\n events.append(json.loads(line))\n return events\n\ndef find_events(events, class_uid, **filters):\n return [e for e in events\n if e[\"class_uid\"] == class_uid\n and all(e.get(k) == v for k, v in filters.items())]\n\n# Example: find all denied CONNECT events\ndenied = find_events(events, 4001, action_id=2, activity_id=1)\n```\n\n### Phase 5: Deprecate flat log fields in gRPC\n\nOnce the gateway and any downstream consumers have adopted `ocsf_json`:\n1. Stop populating the flat `message`/`level`/`fields` on `SandboxLogLine`\n2. Mark them as deprecated in the proto\n3. Gateway can parse `ocsf_json` directly for storage/indexing\n\n---\n\n## Sample OCSF JSON Output\n\nWhat a CONNECT allow event looks like in `/var/log/openshell.log`:\n\n```json\n{\n \"class_uid\": 4001,\n \"class_name\": \"Network Activity\",\n \"category_uid\": 4,\n \"category_name\": \"Network Activity\",\n \"type_uid\": 400101,\n \"type_name\": \"Network Activity: Open\",\n \"activity_id\": 1,\n \"activity_name\": \"Open\",\n \"action_id\": 1,\n \"action\": \"Allowed\",\n \"severity_id\": 1,\n \"severity\": \"Informational\",\n \"disposition_id\": 1,\n \"disposition\": \"Allowed\",\n \"time\": 1741862400000,\n \"time_dt\": \"2026-03-13T12:00:00.000Z\",\n \"message\": \"CONNECT\",\n \"metadata\": {\n \"version\": \"1.3.0\",\n \"product\": {\n \"name\": \"OpenShell Sandbox\",\n \"vendor_name\": \"OpenShell\",\n \"version\": \"0.14.0\"\n },\n \"log_name\": \"openshell-sandbox\",\n \"log_provider\": \"openshell-ocsf\"\n },\n \"src_endpoint\": {\n \"ip\": \"10.42.1.5\",\n \"port\": 48230\n },\n \"dst_endpoint\": {\n \"ip\": \"api.github.com\",\n \"port\": 443\n },\n \"proxy_endpoint\": {\n \"ip\": \"127.0.0.1\",\n \"port\": 3128\n },\n \"actor\": {\n \"process\": {\n \"name\": \"curl\",\n \"pid\": 1234,\n \"cmd_line\": \"curl https://api.github.com/repos\",\n \"lineage\": [\"bash\", \"sh\", \"supervisor\"]\n }\n },\n \"firewall_rule\": {\n \"name\": \"default-allow-github\"\n },\n \"status_id\": 1,\n \"status\": \"Success\"\n}\n```\n\n---\n\n## Risks and Mitigations\n\n| Risk | Impact | Mitigation |\n|------|--------|------------|\n| JSON serialization overhead per event | Latency on hot proxy path | Benchmark. The CONNECT/FORWARD/L7_REQUEST paths are the most frequent. Pre-allocate buffers in the emitter. If needed, use `simd-json` or `serde_json::to_writer` directly to the non-blocking appender. |\n| Log file size increase (JSON >> text) | Disk pressure in long-lived sandboxes | JSON is ~2-3x larger than fmt::Full. Sandboxes are ephemeral and short-lived. If needed, add log rotation via `tracing-appender::rolling`. |\n| E2E test breakage during migration | CI red | Migrate tests per-phase alongside the call sites. Run CI at each phase boundary. |\n| OCSF schema evolution (1.3.0 → 1.4.0+) | Schema drift | Pin to 1.3.0. Metadata carries `version`. Upgrade is a version bump + field additions (OCSF is additive). |\n| gRPC backward compatibility | Gateway consumers break | Dual-populate `ocsf_json` + flat fields during transition (Phase 5 is separate). |\n\n---\n\n## Open Questions\n\n1. **Log rotation:** Should we add `tracing-appender::rolling` (e.g., daily or\n 10MB max) now that JSON lines are larger? The current setup has no rotation.\n\n2. **OCSF validation in CI:** Should we add a CI step that validates sample\n OCSF output against the official OCSF JSON schema? The schema is published\n at `https://schema.ocsf.io/1.3.0/doc`.\n\n3. **`unmapped` policy:** For Base Event [0] events, how much domain-specific\n context should go into `unmapped` vs being dropped? E.g., network namespace\n veth names, route refresh interval values.\n" -} -``` - -**Error:** -``` -Error: The user has specified a rule which prevents you from using this specific tool call.

-### Phase 2: Wire up the emitter - -- Remove file layer from tracing subscriber in `main.rs` -- Initialize `OcsfEmitter` with the `/var/log/openshell.log` appender -- Pass `Arc` into `run_sandbox()` and subsystems -- Add `optional string ocsf_json = 8` to `SandboxLogLine` proto -- Update `LogPushLayer` to consume from emitter channel -

This is a first-class OCSF field that enables efficient filtering without parsing. - -**`firewall_rule.name`** carries the matched policy name. Omitted (not `-`) when no policy matched. This is cleaner than the current `policy="-"` sentinel. - -**`actor.process`** on FORWARD events gives process attribution (binary, pid, cmdline, parent). The L7_REQUEST events lack this because the relay runs inside an already-established tunnel -- the process info lives on the parent CONNECT event. We could back-reference it via a correlation ID if needed later. - -**`unmapped`** holds domain-specific fields that don't have an OCSF home (inference protocol/kind, `l7_protocol`). This is the OCSF-sanctioned escape hatch -- consumers know to look here for vendor extensions. - ---- - -## User - -Wow those are big. But that's ok.

The user's question is whether the `openshell-ocsf` crate can be shared between the sandbox (producer), CLI (consumer), and TUI (consumer) to provide nice human-readable formatting. - -Key findings: -1. CLI uses `print_log_line()` in `run.rs:3954-3984` - simple text format -2. TUI uses `render_log_line()` in `sandbox_logs.rs:230-265` - smart field ordering, color coding -3. Both consume `SandboxLogLine` proto from the gateway -4. The TUI already has custom "smart ordering" for CONNECT and L7_REQUEST fields - - -5. The solution is to have `openshell-ocsf` handle both serialization in the sandbox and deserialization plus formatting in the CLI and TUI, eliminating the need for custom rendering logic in each consumer. - -This works really well. The data flow is clean -- the gateway is already a passthrough for `SandboxLogLine`, and both the CLI and TUI already have their own formatting layers. Here's how `openshell-ocsf` as a shared crate eliminates the duplication and gives you typed rendering. - -## Current state - -Both consumers format logs independently with ad-hoc logic: - -**CLI** (`run.rs:3954-3984`) -- flat text, alphabetical fields: -``` -[1700000000.456] [sandbox] [INFO ] [openshell_sandbox::proxy] CONNECT action=allow dst_host=example.com dst_port=443 ... -``` - -**TUI** (`sandbox_logs.rs:230-265`) -- hardcoded "smart ordering" for known message types: -``` -12:00:01 sandbox INFO CONNECT action=allow dst_host=example.com dst_port=443 policy=my-policy ... -``` - -The TUI has a hand-maintained `ordered_fields()` function (`sandbox_logs.rs:351-391`) that special-cases `"CONNECT"` and `"L7_REQUEST"` messages to order fields by importance. Everything else falls back to alphabetical. This is the exact kind of thing that should live on the type. - -## How `openshell-ocsf` as a shared crate changes this - -The crate serves three roles depending on who imports it: - -``` -crates/openshell-ocsf/ - src/ - lib.rs - ... - display.rs # Human-readable formatting (NEW) - display/ - network_activity.rs - http_activity.rs - ssh_activity.rs - process_activity.rs - detection_finding.rs - application_lifecycle.rs - config_state_change.rs - base_event.rs -``` - -### Dependency graph - -``` -openshell-ocsf (shared: types + serialize + deserialize + display) - ^ ^ ^ - | | | -openshell-sandbox openshell-cli openshell-tui -(emit events) (parse + render) (parse + render) -``` - -The gateway (`openshell-server`) does NOT need to depend on this crate at all. It just passes `ocsf_json` through as an opaque string on `SandboxLogLine`. This is important -- the gateway stays thin. - -### What each consumer gets - -**Sandbox (producer):** -```rust -// Uses builders + OcsfEmitter as in the plan -ocsf.emit( - HttpActivity::post() - .allowed() - .severity_info() - .dst_endpoint("api.openai.com", 443) - .http_path("/v1/chat/completions") - .policy_name("allow-openai-chat") - .message("L7_REQUEST") -); -``` - -**CLI (consumer)** -- `print_log_line()` becomes: -```rust -use openshell_ocsf::OcsfEvent; - -fn print_log_line(log: &SandboxLogLine) { - if let Some(json) = &log.ocsf_json { - // Typed deserialization -> human formatting - let event = OcsfEvent::from_json(json); - println!("{}", event.display_compact()); - } else { - // Legacy fallback for old sandbox versions - print_legacy_log_line(log); - } -} -``` - -Output: -``` -[12:00:01.234] [sandbox] INFO HTTP POST /v1/chat/completions -> api.openai.com:443 ALLOWED policy=allow-openai-chat -``` - -**TUI (consumer)** -- `render_log_line()` becomes: -```rust -use openshell_ocsf::OcsfEvent; - -fn render_log_line(line: &LogLine, width: u16) -> Line<'_> { - if let Some(json) = &line.ocsf_json { - let event = OcsfEvent::from_json(json); - event.display_tui(width) // returns ratatui Spans with colors - } else { - render_legacy_log_line(line, width) - } -} -``` - -### The `Display` trait on events - -Each OCSF class implements formatting that knows which fields matter and in what order -- no more hardcoded message-name matching: - -```rust -// In openshell-ocsf/src/display/http_activity.rs - -impl HttpActivityBody { - /// One-line compact format for terminal output - pub fn display_compact(&self, envelope: &OcsfEnvelope) -> String { - // "HTTP POST /v1/chat/completions -> api.openai.com:443 ALLOWED policy=allow-openai-chat" - format!( - "HTTP {} {} -> {}:{} {}{}", - self.http_request.method, - self.http_request.url.path, - envelope.dst_endpoint.hostname_or_ip(), - envelope.dst_endpoint.port, - envelope.disposition_label(), - self.policy_suffix(), - ) - } - - /// Multi-line detail format for TUI popup / verbose CLI - pub fn display_detail(&self, envelope: &OcsfEnvelope) -> Vec<(String, String)> { - vec![ - ("Action".into(), envelope.action_label()), - ("Method".into(), self.http_request.method.clone()), - ("Path".into(), self.http_request.url.path.clone()), - ("Destination".into(), format!("{}:{}", ...)), - ("Source".into(), format!("{}:{}", ...)), - ("Policy".into(), self.firewall_rule_name()), - ("Reason".into(), envelope.status_detail_or_empty()), - // ... actor/process fields if present - ] - } -} -``` - -The TUI's detail popup (`sandbox_logs.rs:125-203`) currently builds this list manually from the `fields` HashMap. With typed events, it gets a structured `display_detail()` that returns labeled key-value pairs in the correct order for that event class. No more `ordered_fields()` switch statement. - -### What this eliminates - -| Current code | Replaced by | -|-------------|-------------| -| TUI `ordered_fields()` (40 lines, hardcoded field order per message type) | `HttpActivityBody::display_compact()` / `NetworkActivityBody::display_compact()` | -| TUI `render_log_line()` field formatting loop | `OcsfEvent::display_tui()` returning ratatui `Spans` | -| TUI `draw_detail_popup()` field rendering | `OcsfEvent::display_detail()` returning `Vec<(label, value)>` | -| CLI `print_log_line()` field formatting | `OcsfEvent::display_compact()` | -| CLI alphabetical field sort | Gone -- each class defines its own field priority | - -### Backward compatibility - -Both CLI and TUI check `ocsf_json.is_some()` and fall back to the existing `message` + `fields` rendering for log lines from older sandboxes that haven't been upgraded yet. This means you can roll out the crate without a coordinated release of every component. - -### Deserialization approach - -Since we're using structured types, `OcsfEvent::from_json()` dispatches on `class_uid`: - -```rust -pub enum OcsfEvent { - NetworkActivity(OcsfEnvelope), - HttpActivity(OcsfEnvelope), - SshActivity(OcsfEnvelope), - ProcessActivity(OcsfEnvelope), - DetectionFinding(OcsfEnvelope), - ApplicationLifecycle(OcsfEnvelope), - ConfigStateChange(OcsfEnvelope), - BaseEvent(OcsfEnvelope), -} - -impl OcsfEvent { - pub fn from_json(json: &str) -> Result { - let peek: ClassPeek = serde_json::from_str(json)?; - match peek.class_uid { - 4001 => Ok(Self::NetworkActivity(serde_json::from_str(json)?)), - 4002 => Ok(Self::HttpActivity(serde_json::from_str(json)?)), - 4007 => Ok(Self::SshActivity(serde_json::from_str(json)?)), - // ... - } - } -} -``` - -This gives the CLI and TUI full type information to format each event class differently, while the gateway never needs to parse the JSON at all. - ---- - -Want me to add this display/shared-crate design into the plan document, or is there anything you'd want to adjust about the approach? - ---- - -## User - -Yeah can you write the plan out to disk with all of this so far. - ---- - -## Assistant (Plan · claude-opus-4-6 · 8.0s) - - - -I'm in plan mode so I can't write files to disk right now.

You can now continue with the user's answers in mind. -``` - ---- - -## Assistant (Plan · claude-opus-4-6 · 12.7s) - -Good calls. Let me summarize the resolved decisions: - -**Log rotation:** Size-based via `tracing-appender::rolling` with a max file size (50MB). This is the `max_log_files` + size-based rolling feature in `tracing-appender`. The `OcsfEmitter` will use this instead of raw `OpenOptions::append`. One thing to note -- `tracing-appender` 0.2 has `RollingFileAppender` with time-based rotation built in, but size-based requires the `rolling` feature with a custom trigger or upgrading to the newer API. We may need to evaluate whether `tracing-appender` 0.2's API is sufficient or if we roll our own simple size check on write. I'll note that in the plan as a spike item. - -**OCSF validation:** Unit tests per class + vendored OCSF 1.3.0 JSON schema in the repo. The `jsonschema` crate validates sample output against it. This catches field naming/typing errors at test time without any CI network dependency. The schema files go under something like `crates/openshell-ocsf/schema/1.3.0/`. - -**Unmapped policy:** Preserve all current fields. Every tracing field that exists today goes into `unmapped` for Base Event [0] events. No information loss. For the typed classes (Network Activity, HTTP Activity, etc.), fields that map to OCSF attributes go to their proper location, and anything domain-specific that doesn't fit goes into `unmapped` (e.g., `l7_protocol`, `inference_kind`). - -All three questions are resolved. The plan is ready to write -- switch out of plan mode and I'll put it at `architecture/plans/ocsf-adoption.md`. - ---- - -## User - -Ok write it out - ---- - -## Assistant (Build · claude-opus-4-6 · 5.6s) - -**Tool: todowrite** - -**Input:** -```json -{ - "todos": [ - { - "content": "Write complete OCSF adoption plan to architecture/plans/ocsf-adoption.md", - "status": "in_progress", - "priority": "high" - } - ] -} -``` - -**Output:** -``` -[ - { - "content": "Write complete OCSF adoption plan to architecture/plans/ocsf-adoption.md", - "status": "in_progress", - "priority": "high" - } -] -``` - ---- - -## Assistant (Build · claude-opus-4-6 · 100.3s) - -**Tool: write** - -**Input:** -```json -{} -``` - -**Error:** -``` -Tool execution aborted -``` - ---- - -## User - -did you get stuck - ---- - -## Assistant (Build · claude-opus-4-6 · 144.3s) - -_Thinking:_ - -The user is asking if I got stuck.
