 For info about how [API versioning](https://xrpl.org/request-formatting.html#api-versioning) works, including examples, please view the [XLS-22d spec](https://github.com/XRPLF/XRPL-Standards/discussions/54). For details about the implementation of API versioning, view the [implementation PR](https://github.com/XRPLF/rippled/pull/3155). API versioning ensures existing integrations and users continue to receive existing behavior, while those that request a higher API version will experience new behavior.
 
-The API version controls the API behavior you see. This includes what properties you see in responses, what parameters you're permitted to send in requests, and so on. You specify the API version in each of your requests. When a breaking change is introduced to the `xrpld` API, a new version is released. To avoid breaking your code, you should set (or increase) your version when you're ready to upgrade.

You specify the API version in each of your requests. When a breaking change is introduced to the `rippled` API, a new version is released. To avoid breaking your code, you should set (or increase) your version when you're ready to upgrade.
 
 The [commandline](https://xrpl.org/docs/references/http-websocket-apis/api-conventions/request-formatting/#commandline-format) always uses the latest API version. The command line is intended for ad-hoc usage by humans, not programs or automated scripts. The command line is not meant for use in production code.
 
-For a log of breaking changes, see the **API Version [number]** headings. In general, breaking changes are associated with a particular API Version number. For non-breaking changes, scroll to the **XRP Ledger version [x.y.z]** headings. Non-breaking changes are associated with a particular XRP Ledger (`xrpld`) release.

-### Additions
-
-- `server_definitions`: Added the following new sections to the response ([#6321](https://github.com/XRPLF/rippled/pull/6321)):
-  - `TRANSACTION_FORMATS`: Describes the fields and their optionality for each transaction type, including common fields shared across all transactions.
-  - `LEDGER_ENTRY_FORMATS`: Describes the fields and their optionality for each ledger entry type, including common fields shared across all ledger entries.
-  - `TRANSACTION_FLAGS`: Maps transaction type names to their supported flags and flag values.
-  - `LEDGER_ENTRY_FLAGS`: Maps ledger entry type names to their flags and flag values.
-  - `ACCOUNT_SET_FLAGS`: Maps AccountSet flag names (asf flags) to their numeric values.
-
-### Bugfixes
-
-- Peer Crawler: The `port` field in `overlay.active[]` now consistently returns an integer instead of a string for outbound peers. [#6318](https://github.com/XRPLF/rippled/pull/6318)
-- `ping`: The `ip` field is no longer returned as an empty string for proxied connections without a forwarded-for header. It is now omitted, consistent with the behavior for identified connections. [#6730](https://github.com/XRPLF/rippled/pull/6730)
-- gRPC `GetLedgerDiff`: Fixed error message that incorrectly said "base ledger not validated" when the desired ledger was not validated. [#6730](https://github.com/XRPLF/rippled/pull/6730)
+This version is supported by all `rippled` versions. For WebSocket and HTTP JSON-RPC requests, it is currently the default API version used when no `api_version` is specified.

-All code must pass `clang-tidy` checks according to the settings in [`.clang-tidy`](./.clang-tidy).
-
-There is a Continuous Integration job that runs clang-tidy on pull requests. The CI will check:
-
-- All changed C++ files (`.cpp`, `.h`, `.ipp`) when only code files are modified
-- **All files in the repository** when the `.clang-tidy` configuration file is changed
-
-This ensures that configuration changes don't introduce new warnings across the codebase.
-
-### Installing clang-tidy
-
-See the [environment setup guide](./docs/build/environment.md#clang-tidy) for platform-specific installation instructions.
-
-### Running clang-tidy locally
-
-Before running clang-tidy, you must build the project to generate required files (particularly protobuf headers). Refer to [`BUILD.md`](./BUILD.md) for build instructions.
-
-#### Via pre-commit (recommended)
-
-If you have already installed the pre-commit hooks (see above), you can run clang-tidy on your staged files using:
-
-```
-TIDY=1 pre-commit run clang-tidy
-```
-
-This runs clang-tidy locally with the same configuration/flags as CI, scoped to your staged C++ files. The `TIDY=1` environment variable is required to opt in — without it the hook is skipped.
-
-You can also have clang-tidy run automatically on every `git commit` by setting `TIDY=1` in your shell environment:
-
-```
-export TIDY=1
-```
-
-With this set, the hook will run as part of `git commit` alongside the other pre-commit checks.
-
-#### Manually
-
-Then run clang-tidy on your local changes:
-
-```
-run-clang-tidy -p build -allow-no-checks src tests
-```
-
-This will check all source files in the `src`, `include` and `tests` directories using the compile commands from your `build` directory.
-If you wish to automatically fix whatever clang-tidy finds _and_ is capable of fixing, add `-fix` to the above command:
-
-```
-run-clang-tidy -p build -quiet -fix -allow-no-checks src tests

-## What is Distributed Tracing?
-
-Distributed tracing is a method for tracking data objects as they flow through distributed systems. In a network like XRP Ledger, a single transaction touches multiple independent nodes—each with no shared memory or logging. Distributed tracing connects these dots.
-
-**Without tracing:** You see isolated logs on each node with no way to correlate them.
-
-**With tracing:** You see the complete journey of a transaction or an event across all nodes it touched.

-## Core Concepts
-
-### 1. Trace
-
-A **trace** represents the entire journey of a request through the system. It has a unique `trace_id` that stays constant across all nodes.
-
-```
-Trace ID: abc123
-├── Node A: received transaction
-├── Node B: relayed transaction
-├── Node C: included in consensus
-└── Node D: applied to ledger
-```
-
-### 2. Span
-
-A **span** represents a single unit of work within a trace. Each span has:
-
-| Attribute        | Description                      | Example                    |
-| ---------------- | -------------------------------- | -------------------------- |
-| `trace_id`       | Identifies the trace             | `event123`                 |
-| `span_id`        | Unique identifier                | `span456`                  |
-| `parent_span_id` | Parent span (if any)             | `p_span123`                |
-| `name`           | Operation name                   | `rpc.submit`               |
-| `start_time`     | When work began (local time)     | `2024-01-15T10:30:00Z`     |
-| `end_time`       | When work completed (local time) | `2024-01-15T10:30:00.050Z` |
-| `attributes`     | Key-value metadata               | `tx.hash=ABC...`           |
-| `status`         | OK, ERROR MSG                    | `OK`                       |
-
-### 3. Trace Context
-
-**Trace context** is the data that propagates between services to link spans together. It contains:
-
-- `trace_id` - The trace this span belongs to
-- `span_id` - The current span (becomes parent for child spans)
-- `trace_flags` - Sampling decisions
-

-
-## How Spans Form a Trace
-
-Spans have parent-child relationships forming a tree structure:
-
-```mermaid
-flowchart TB
-    subgraph trace["Trace: abc123"]
-        A["tx.submit<br/>span_id: 001<br/>50ms"] --> B["tx.validate<br/>span_id: 002<br/>5ms"]
-        A --> C["tx.relay<br/>span_id: 003<br/>10ms"]
-        A --> D["tx.apply<br/>span_id: 004<br/>30ms"]
-        D --> E["ledger.update<br/>span_id: 005<br/>20ms"]
-    end
-
-    style A fill:#0d47a1,stroke:#082f6a,color:#ffffff
-    style B fill:#1b5e20,stroke:#0d3d14,color:#ffffff
-    style C fill:#1b5e20,stroke:#0d3d14,color:#ffffff
-    style D fill:#1b5e20,stroke:#0d3d14,color:#ffffff
-    style E fill:#bf360c,stroke:#8c2809,color:#ffffff
-```
-
-**Reading the diagram:**
-
-- **tx.submit (blue, root)**: The top-level span representing the entire transaction submission; all other spans are its descendants.
-- **tx.validate, tx.relay, tx.apply (green)**: Direct children of tx.submit, representing the three main stages -- validation, relay to peers, and application to the ledger.
-- **ledger.update (red)**: A grandchild span nested under tx.apply, representing the actual ledger state mutation triggered by applying the transaction.
-- **Arrows (parent to child)**: Each arrow indicates a parent-child span relationship where the parent's completion depends on the child finishing.
-
-The same trace visualized as a **timeline (Gantt chart)**:
-
-```

-## Span Relationships
-
-Spans don't always form simple parent-child trees. Distributed tracing defines several relationship types to capture different causal patterns:
-
-### 1. Parent-Child (ChildOf)
-
-The default relationship. The parent span **depends on** or **contains** the child span. The child runs within the scope of the parent.
-
-```
-tx.submit (parent)
-├── tx.validate (child)     ← parent waits for this
-├── tx.relay (child)        ← parent waits for this
-└── tx.apply (child)        ← parent waits for this
-```
-
-**When to use:** Synchronous calls, nested operations, any case where the parent's completion depends on the child.
-
-### 2. Follows-From
-
-A causal relationship where the first span **triggers** the second, but does **not wait** for it. The originator fires and moves on.
-
-```
-Time →
-
-tx.receive [=======]
-                     ↓ triggers (follows-from)
-              tx.relay   [===========]   ← runs independently
-```
-
-**When to use:** Asynchronous jobs, queued work, fire-and-forget patterns. For example, a node receives a transaction and queues it for relay — the relay span _follows from_ the receive span but the receiver doesn't wait for relaying to complete.
-
-> **OpenTracing** defined `FollowsFrom` as a first-class reference type alongside `ChildOf`.
-> **OpenTelemetry** represents this using **Span Links** with descriptive attributes instead (see below).
-
-### 3. Span Links (Cross-Trace and Non-Hierarchical)
-
-Links connect spans that are **causally related but not in a parent-child hierarchy**. Unlike parent-child, links can cross trace boundaries.
-
-```
-Trace A                          Trace B
-──────                           ──────
-batch.schedule                   batch.execute
-├─ item.enqueue (span X)    ┌──► process.item
-├─ item.enqueue (span Y) ───┤    (links to X, Y, Z)
-├─ item.enqueue (span Z)    └──►
-```
-
-**Use cases:**
-
-| Pattern              | Description                                                                 |
-| -------------------- | --------------------------------------------------------------------------- |
-| **Batch processing** | A batch span links back to all individual spans that contributed to it      |
-| **Fan-in**           | An aggregation span links to the multiple producer spans it merges          |
-| **Fan-out**          | Multiple downstream spans link back to the single span that triggered them  |
-| **Async handoff**    | A deferred job links back to the request that queued it (follows-from)      |
-| **Cross-trace**      | Correlating spans across independent traces (e.g., retries, related events) |
-
-**Link structure:** Each link carries the target span's context plus optional attributes:
-
-```
-Link {
-    trace_id:   <target trace>
-    span_id:    <target span>
-    attributes: { "link.description": "triggered by batch scheduler" }
-}
-```

-## Trace ID Generation
-
-A `trace_id` is a 128-bit (16-byte) identifier that groups all spans belonging to one logical operation. How it's generated determines how easily you can find and correlate traces later.
-
-### General Approaches
-
-#### 1. Random (W3C Default)
-
-Generate a random 128-bit ID when a trace starts. Standard approach for most services.
-
-```
-trace_id = random_128_bits()
-```
-
-| Pros                        | Cons                                          |
-| --------------------------- | --------------------------------------------- |
-| Simple, standard            | No natural correlation to domain events       |
-| Guaranteed unique per trace | If propagation is lost, trace is broken       |
-| Works with all OTel tooling | "Find trace for TX abc" requires index lookup |
-
-#### 2. Deterministic (Derived from Domain Data)
-
-Compute the trace_id from a hash of a natural identifier. Every node independently derives the **same** trace_id for the same event.
-
-```
-trace_id = SHA-256(domain_identifier)[0:16]   // truncate to 128 bits
-```
-
-| Pros                                                | Cons                                                       |
-| --------------------------------------------------- | ---------------------------------------------------------- |
-| Propagation-resilient — same ID computed everywhere | Same event processed twice (retry) shares trace_id         |
-| Natural search — domain ID maps directly to trace   | Non-standard (tooling assumes random)                      |
-| No coordination needed between nodes                | 256→128 bit truncation (collision risk negligible at ~2⁶⁴) |
-
-#### 3. Hybrid (Deterministic Prefix + Random Suffix)
-
-First 8 bytes derived from domain data, last 8 bytes random.
-
-```
-trace_id = SHA-256(domain_identifier)[0:8] || random_64_bits()
-```
-
-| Pros                                        | Cons                                     |
-| ------------------------------------------- | ---------------------------------------- |
-| Prefix search: "find all traces for TX abc" | Must propagate to maintain full trace_id |
-| Unique per processing instance              | More complex generation logic            |
-| Retries get distinct trace_ids              | Partial correlation only (prefix match)  |
-
-### XRPL Workflow Analysis
-
-XRPL has a unique advantage: its core workflows produce **globally unique 256-bit hashes** that are known on every node. This makes deterministic trace_id generation practical in ways most systems can't achieve.
-
-#### Natural Identifiers by Workflow
-
-| Workflow            | Natural Identifier                | Size       | Known at Start?               | Same on All Nodes?               |
-| ------------------- | --------------------------------- | ---------- | ----------------------------- | -------------------------------- |
-| **Transaction**     | Transaction hash (`tid_`)         | 256-bit    | Yes — computed before signing | Yes — hash of canonical tx data  |
-| **Consensus round** | Previous ledger hash + ledger seq | 256+32 bit | Yes — known when round opens  | Yes — all validators agree       |
-| **Validation**      | Ledger hash being validated       | 256-bit    | Yes — from consensus result   | Yes — same closed ledger         |
-| **Ledger catch-up** | Target ledger hash                | 256-bit    | Yes — we know what to fetch   | Yes — identifies ledger globally |
-
-#### Where These Identifiers Live in Code
-
-```
-Transaction:     STTx::getTransactionID()     → uint256 tid_
-                 TMTransaction::rawTransaction → recompute hash from bytes
-
-Consensus:       ConsensusProposal::prevLedger_ → uint256 (previous ledger hash)
-                 ConsensusProposal::position_   → uint256 (TxSet hash)
-                 LedgerHeader::seq              → uint32_t (ledger sequence)
-
-Validation:      STValidation::getLedgerHash()  → uint256
-                 STValidation::getNodeID()      → NodeID (160-bit)
-
-Ledger fetch:    InboundLedger constructor      → uint256 hash, uint32_t seq
-                 TMGetLedger::ledgerHash        → bytes (uint256)
-```
-
-### Recommended Strategy: Workflow-Scoped Deterministic
-
-Each workflow type derives its trace_id from its natural domain identifier:
-
-```
-Transaction trace:   trace_id = SHA-256("tx"    || tx_hash)[0:16]
-Consensus trace:     trace_id = SHA-256("cons"  || prev_ledger_hash || ledger_seq)[0:16]
-Ledger catch-up:     trace_id = SHA-256("fetch" || target_ledger_hash)[0:16]
-```
-
-The string prefix (`"tx"`, `"cons"`, `"fetch"`) prevents collisions between workflows that might share underlying hashes.
-
-**Why this works for XRPL:**
-
-1. **Propagation-resilient** — Even if a P2P message drops trace context, every node independently computes the same trace_id from the same tx_hash or ledger_hash. Spans still correlate.
-
-2. **Zero-cost search** — "Show me the trace for transaction ABC" becomes a direct lookup: compute `SHA-256("tx" || ABC)[0:16]` and query. No secondary index needed.
-
-3. **Cross-workflow linking via Span Links** — A consensus trace links to individual transaction traces. A validation span links to the consensus trace. This connects the full picture without forcing everything into one giant trace.
-
-### Cross-Workflow Correlation
-
-Each workflow gets its own trace. Span Links tie them together:

-**Reading the diagram:**
-
-- **Transaction Trace (blue)**: An independent trace whose `trace_id` is deterministically derived from the transaction hash. Contains receive, validate, and relay spans.
-- **Consensus Trace (green)**: An independent trace whose `trace_id` is derived from the previous ledger hash and sequence number. Covers the open, propose, and accept phases.
-- **Validation (red)**: Validation spans live within the consensus trace (not a separate trace). They are created after the accept phase completes.
-- **Catch-Up Trace (purple)**: An independent trace for ledger acquisition, derived from the target ledger hash. Used when a node is behind and fetching missing ledgers.
-- **Dotted arrows (span links)**: Cross-trace correlations. Consensus links to transaction traces it included; catch-up links to the consensus trace that produced the target ledger.
-- **Solid arrow (C3 to V1)**: A parent-child relationship -- validation spans are direct children of the consensus accept span within the same trace.
-
-**How a query flows:**
-
-```
-"Why was TX abc slow?"
-  1. Compute trace_id = SHA-256("tx" || abc)[0:16]
-  2. Find transaction trace → see it was included in consensus round N
-  3. Follow span link → consensus trace for round N
-  4. See which phase was slow (propose? accept?)
-  5. If a node was catching up, follow link → catch-up trace
-```
-
-### Trade-offs to Consider
-
-| Concern                       | Mitigation                                                                                                                    |
-| ----------------------------- | ----------------------------------------------------------------------------------------------------------------------------- |
-| **Retries get same trace_id** | Add `attempt` attribute to root span; spans have unique span_ids and timestamps                                               |
-| **256→128 bit truncation**    | Birthday-bound collision at ~2⁶⁴ operations — negligible for XRPL's throughput                                                |
-| **Non-standard generation**   | OTel spec allows any 16-byte non-zero value; tooling works on the hex string                                                  |
-| **Hash computation cost**     | SHA-256 is ~0.3μs per call; XRPL already computes these hashes for other purposes                                             |
-| **Late-binding identifiers**  | Ledger hash isn't known until after consensus — validation spans use ledger_seq as fallback, then link to the consensus trace |

-## Distributed Traces Across Nodes
-
-In distributed systems like xrpld, traces span **multiple independent nodes**. The trace context must be propagated in network messages:
-
-```mermaid
-sequenceDiagram
-    participant Client
-    participant NodeA as Node A
-    participant NodeB as Node B
-    participant NodeC as Node C
-
-    Client->>NodeA: Submit TX<br/>(no trace context)
-
-    Note over NodeA: Creates new trace<br/>trace_id: abc123<br/>span: tx.receive
-
-    NodeA->>NodeB: Relay TX<br/>(trace_id: abc123, parent: 001)
-
-    Note over NodeB: Creates child span<br/>span: tx.relay<br/>parent_span_id: 001
-
-    NodeA->>NodeC: Relay TX<br/>(trace_id: abc123, parent: 001)
-
-    Note over NodeC: Creates child span<br/>span: tx.relay<br/>parent_span_id: 001
-
-    Note over NodeA,NodeC: All spans share trace_id: abc123<br/>enabling correlation across nodes
-```
-
-**Reading the diagram:**
-
-- **Client**: The external entity that submits a transaction. It does not carry trace context -- the trace originates at the first node.
-- **Node A**: The entry point that creates a new trace (trace_id: abc123) and the root span `tx.receive`. It relays the transaction to peers with trace context attached.
-- **Node B and Node C**: Peer nodes that receive the relayed transaction along with the propagated trace context. Each creates a child span under Node A's span, preserving the same `trace_id`.
-- **Arrows with trace context**: The relay messages carry `trace_id` and `parent_span_id`, allowing each downstream node to link its spans back to the originating span on Node A.
-

-
-## Context Propagation
-
-For traces to work across nodes, **trace context must be propagated** in messages.

-| Field         | Size     | Description                                             |
-| ------------- | -------- | ------------------------------------------------------- |
-| `trace_id`    | 16 bytes | Identifies the entire trace (constant across all nodes) |
-| `span_id`     | 8 bytes  | The sender's current span (becomes parent on receiver)  |
-| `trace_flags` | 1 byte   | Sampling decision (bit 0 = sampled; bits 1-7 reserved)  |
-| `trace_state` | variable | Optional vendor-specific data (typically omitted)       |
-
-### How span_id Changes at Each Hop
-
-Only **one** `span_id` travels in the context - the sender's current span. Each node:
-
-1. Extracts the received `span_id` and uses it as the `parent_span_id`
-2. Creates a **new** `span_id` for its own span
-3. Sends its own `span_id` as the parent when forwarding
-
-```
-Node A                      Node B                      Node C
-──────                      ──────                      ──────
-
-Span AAA                    Span BBB                    Span CCC
-   │                           │                           │

-├─ trace_id: abc123         ├─ trace_id: abc123         ├─ trace_id: abc123
-├─ span_id: AAA ──────────► ├─ span_id: BBB ──────────► ├─ span_id: CCC ──────►

-                          parent = AAA               parent = BBB
-```
-
-The `trace_id` stays constant, but `span_id` **changes at every hop** to maintain the parent-child chain.
-
-### Propagation Formats
-
-There are two patterns:
-
-### HTTP/RPC Headers (W3C Trace Context)
-
-```
-traceparent: 00-4bf92f3577b34da6a3ce929d0e0e4736-00f067aa0ba902b7-01
-             │  │                                │                │
-             │  │                                │                └── Flags (sampled)
-             │  │                                └── Parent span ID (16 hex)
-             │  └── Trace ID (32 hex)
-             └── Version
-```
-
-### Protocol Buffers (xrpld P2P messages)
-
-```protobuf
-message TMTransaction {
-    bytes rawTransaction = 1;
-    // ... existing fields ...
-
-    // Trace context extension
-    bytes trace_parent = 100;  // W3C traceparent
-    bytes trace_state = 101;   // W3C tracestate
-}
-```
-

-
-## Sampling
-
-Not every trace needs to be recorded. **Sampling** reduces overhead:
-
-### Head Sampling (at trace start)
-
-```
-Request arrives → Random 10% chance → Record or skip entire trace
-```
-
-- ✅ Low overhead
-- ❌ May miss interesting traces
-
-### Tail Sampling (after trace completes)
-
-```
-Trace completes → Collector evaluates:
-                  - Error? → KEEP
-                  - Slow? → KEEP
-                  - Normal? → Sample 10%
-```
-
-- ✅ Never loses important traces
-- ❌ Higher memory usage at collector

-**Reading the diagram:**
-
-- **Core Services (blue)**: The entry points into xrpld -- RPC Server handles client requests, Overlay manages peer-to-peer networking, Consensus drives agreement, and ValidatorList manages trusted validators.
-- **JobQueue (center)**: The asynchronous thread pool that decouples Core Services from the Processing and Application layers. All work flows through it.
-- **Processing Layer (green)**: Core business logic -- NetworkOPs processes transactions, LedgerMaster manages ledger state, NodeStore handles persistence, and InboundLedgers synchronizes missing data.
-- **Application Services (purple)**: Higher-level features -- PathFinding computes payment routes, TxQ manages fee-based queuing, and LoadManager tracks server load.
-- **Existing Observability (orange)**: The current monitoring stack (PerfLog, Insight, Journal logging) that OpenTelemetry will complement, not replace.
-- **Arrows (Services to JobQueue to layers)**: Work originates at Core Services, is enqueued onto the JobQueue, and dispatched to Processing or Application layers for execution.

-## 1.3 Transaction Flow Diagram
-
-Transaction flow spans multiple nodes in the network. Each node creates linked spans to form a distributed trace:
-
-```mermaid
-sequenceDiagram
-    participant Client
-    participant PeerA as Peer A (Receive)
-    participant PeerB as Peer B (Relay)
-    participant PeerC as Peer C (Validate)
-
-    Client->>PeerA: 1. Submit TX
-
-    rect rgb(230, 245, 255)
-        Note over PeerA: tx.receive SPAN START
-        PeerA->>PeerA: HashRouter Deduplication
-        PeerA->>PeerA: tx.validate (child span)
-    end
-
-    PeerA->>PeerB: 2. Relay TX (with trace ctx)
-
-    rect rgb(230, 245, 255)
-        Note over PeerB: tx.receive (linked span)
-    end
-
-    PeerB->>PeerC: 3. Relay TX
-
-    rect rgb(230, 245, 255)
-        Note over PeerC: tx.receive (linked span)
-        PeerC->>PeerC: tx.process
-    end
-
-    Note over Client,PeerC: DISTRIBUTED TRACE (same trace_id: abc123)
-```
-
-**Reading the diagram:**
-
-- **Client**: The external entity that submits a transaction to Peer A. It has no trace context -- the trace starts at the first node.
-- **Peer A (Receive)**: The entry node that creates the root span `tx.receive`, runs HashRouter deduplication to avoid processing duplicates, and creates a child `tx.validate` span.
-- **Peer A to Peer B arrow**: The relay message carries trace context (trace_id + parent span_id), enabling Peer B to create a linked span under the same trace.
-- **Peer B (Relay)**: Receives the transaction and trace context, creates a `tx.receive` span linked to Peer A's trace, then relays onward.
-- **Peer C (Validate)**: Final hop in this example. Creates a linked `tx.receive` span and runs `tx.process` to fully process the transaction.
-- **Blue rectangles**: Highlight the span boundaries on each node, showing where instrumentation creates and closes spans.
-
-### Trace Structure
-
-```
-trace_id: abc123
-├── span: tx.receive (Peer A)
-│   ├── span: tx.validate
-│   └── span: tx.relay
-├── span: tx.receive (Peer B) [parent: Peer A]
-│   └── span: tx.relay
-└── span: tx.receive (Peer C) [parent: Peer B]
-    └── span: tx.process
-```

-
-## 1.4 Consensus Round Flow
-
-Consensus rounds are multi-phase operations that benefit significantly from tracing:
-
-```mermaid
-flowchart TB
-    subgraph round["consensus.round (root span)"]
-        attrs["Attributes:<br/>xrpl.consensus.ledger.seq = 12345678<br/>xrpl.consensus.mode = proposing<br/>xrpl.consensus.proposers = 35"]
-
-        subgraph open["consensus.phase.open"]
-            open_desc["Duration: ~3s<br/>Waiting for transactions"]
-        end
-
-        subgraph establish["consensus.phase.establish"]
-            est_attrs["proposals_received = 28<br/>disputes_resolved = 3"]
-            est_children["├── consensus.proposal.receive (×28)<br/>├── consensus.proposal.send (×1)<br/>└── consensus.dispute.resolve (×3)"]
-        end
-
-        subgraph accept["consensus.phase.accept"]
-            acc_attrs["transactions_applied = 150<br/>ledger.hash = DEF456..."]
-            acc_children["├── ledger.build<br/>└── ledger.validate"]
-        end
-
-        attrs --> open
-        open --> establish
-        establish --> accept
-    end
-
-    style round fill:#f57f17,stroke:#e65100,color:#ffffff
-    style open fill:#1565c0,stroke:#0d47a1,color:#ffffff
-    style establish fill:#2e7d32,stroke:#1b5e20,color:#ffffff
-    style accept fill:#c2185b,stroke:#880e4f,color:#ffffff
-```
-
-**Reading the diagram:**
-
-- **consensus.round (orange, root span)**: The top-level span encompassing the entire consensus round, with attributes like ledger sequence, mode, and proposer count.
-- **consensus.phase.open (blue)**: The first phase where the node waits (~3s) to collect incoming transactions before proposing.
-- **consensus.phase.establish (green)**: The negotiation phase where validators exchange proposals, resolve disputes, and converge on a transaction set. Child spans track each proposal received/sent and each dispute resolved.
-- **consensus.phase.accept (pink)**: The final phase where the agreed transaction set is applied, a new ledger is built, and the ledger is validated. Child spans cover `ledger.build` and `ledger.validate`.
-- **Arrows (open to establish to accept)**: The sequential flow through the three consensus phases. Each phase must complete before the next begins.

-## 1.5 RPC Request Flow
-
-> **WS** = WebSocket
-
-RPC requests support W3C Trace Context headers for distributed tracing across services:
-
-```mermaid
-flowchart TB
-    subgraph request["rpc.request (root span)"]
-        http["HTTP Request — POST /<br/>traceparent:<br/>00-abc123...-def456...-01"]
-
-        attrs["Attributes:<br/>http.method = POST<br/>net.peer.ip = 192.168.1.100<br/>xrpl.rpc.command = submit"]
-
-        subgraph enqueue["jobqueue.enqueue"]
-            job_attr["xrpl.job.type = jtCLIENT_RPC"]
-        end
-
-        subgraph command["rpc.command.submit"]
-            cmd_attrs["xrpl.rpc.version = 2<br/>xrpl.rpc.role = user"]

-        end
-
-        response["Response: 200 OK<br/>Duration: 45ms"]
-
-        http --> attrs
-        attrs --> enqueue
-        enqueue --> command
-        command --> response
-    end
-
-    style request fill:#2e7d32,stroke:#1b5e20,color:#ffffff
-    style enqueue fill:#1565c0,stroke:#0d47a1,color:#ffffff
-    style command fill:#e65100,stroke:#bf360c,color:#ffffff
-```
-
-**Reading the diagram:**
-
-- **rpc.request (green, root span)**: The outermost span representing the full RPC request lifecycle, from HTTP receipt to response. Carries the W3C `traceparent` header for distributed tracing.
-- **HTTP Request node**: Shows the incoming POST request with its `traceparent` header and extracted attributes (method, peer IP, command name).
-- **jobqueue.enqueue (blue)**: The span covering the asynchronous handoff from the RPC thread to the JobQueue worker thread. The trace context is preserved across this async boundary.
-- **rpc.command.submit (orange)**: The span for the actual command execution, with child spans for deserialization, local validation, and network submission.
-- **Response node**: The final output with HTTP status and total duration, marking the end of the root span.
-- **Arrows (top to bottom)**: The sequential processing pipeline -- receive request, extract attributes, enqueue job, execute command, return response.

-| ------------------------- | ---------------------------------------------------------------------------- | ------------------------------------------------ |
-| **Slow RPC**              | Span showing which phase is slow (parsing, execution, serialization)         | Optimize specific code path                      |
-| **Transaction Stuck**     | Trace stops at validation; error attribute shows reason                      | Fix transaction parameters                       |
-| **Consensus Delay**       | Phase.establish taking too long; proposer attribute shows missing validators | Investigate network connectivity                 |
-| **Memory Spike**          | Large batch of spans correlating with memory increase                        | Tune batch_size or sampling                      |
-| **Network Partition**     | Traces missing cross-node links for specific peer                            | Check peer connectivity                          |
-| **Path Computation Slow** | pathfind.compute span shows high latency; cache miss rate in attributes      | Warm the RippleLineCache, check order book depth |
-| **TxQ Full**              | txq.enqueue spans show evictions; fee.escalate spans increasing              | Monitor fee levels, alert operators              |
-| **Ledger Sync Stalled**   | ledger.acquire spans timing out; peer reliability attributes show issues     | Check peer connectivity, add trusted peers       |
-| **UNL Stale**             | validator.list.fetch spans failing; last_update attribute aging              | Verify validator site URLs, check DNS            |
-
-### 1.8.5 Developer Debugging Workflow
-
-1. **Find Transaction**: Query by `xrpl.tx.hash` to get full trace
-2. **Identify Bottleneck**: Look at span durations to find slowest component
-3. **Check Attributes**: Review `xrpl.tx.validity`, `xrpl.rpc.status` for errors
-4. **Correlate Logs**: Use `trace_id` to find related PerfLog entries
-5. **Compare Nodes**: Filter by `service.instance.id` to compare behavior across nodes

-## 2.1 OpenTelemetry Components
-
-> **OTLP** = OpenTelemetry Protocol
-
-### 2.1.1 SDK Selection
-
-**Primary Choice**: OpenTelemetry C++ SDK (`opentelemetry-cpp`)
-
-| Component                               | Purpose                | Required    |
-| --------------------------------------- | ---------------------- | ----------- |
-| `opentelemetry-cpp::api`                | Tracing API headers    | Yes         |
-| `opentelemetry-cpp::sdk`                | SDK implementation     | Yes         |
-| `opentelemetry-cpp::ext`                | Extensions (exporters) | Yes         |
-| `opentelemetry-cpp::otlp_grpc_exporter` | OTLP/gRPC export       | Recommended |
-| `opentelemetry-cpp::otlp_http_exporter` | OTLP/HTTP export       | Alternative |
-
-### 2.1.2 Instrumentation Strategy
-
-**Manual Instrumentation** (recommended):
-
-| Approach   | Pros                                                            | Cons                                                    |
-| ---------- | --------------------------------------------------------------- | ------------------------------------------------------- |
-| **Manual** | Precise control, optimized placement, xrpld-specific attributes | More development effort                                 |
-| **Auto**   | Less code, automatic coverage                                   | Less control, potential overhead, limited customization |

-```
-
-**Reading the diagram:**
-
-- **xrpld Nodes (blue)**: The source of telemetry data. Each xrpld node exports spans via OTLP/gRPC on port 4317.
-- **OpenTelemetry Collector (red)**: The central aggregation point that receives spans from all nodes. Can run as a sidecar (per-node) or standalone (shared). Handles batching, filtering, and routing.
-- **Observability Backends (green)**: The storage and visualization destinations. Tempo is the recommended backend for both development and production, and Elastic APM is an alternative. The Collector routes to one or more backends.
-- **Arrows (nodes to collector to backends)**: The data pipeline -- spans flow from nodes to the Collector over gRPC, then the Collector fans out to the configured backends.
-
-### 2.2.1 OTLP/gRPC (Recommended)
-
-```cpp
-// Configuration for OTLP over gRPC
-namespace otlp = opentelemetry::exporter::otlp;
-
-otlp::OtlpGrpcExporterOptions opts;
-opts.endpoint = "localhost:4317";
-opts.useTls = true;
-opts.sslCaCertPath = "/path/to/ca.crt";
-```
-
-### 2.2.2 OTLP/HTTP (Alternative)
-
-```cpp
-// Configuration for OTLP over HTTP
-namespace otlp = opentelemetry::exporter::otlp;
-
-otlp::OtlpHttpExporterOptions opts;
-opts.url = "http://localhost:4318/v1/traces";
-opts.content_type = otlp::HttpRequestContentType::kJson;  // or kBinary

-> **TxQ** = Transaction Queue | **UNL** = Unique Node List | **WS** = WebSocket
-
-### 2.3.1 Naming Schema

-```
-
-**Examples**:
-
-- `tx.receive` - Transaction received from peer
-- `consensus.phase.establish` - Consensus establish phase
-- `rpc.command.server_info` - server_info RPC command

-
-| Category        | Attributes Collected                                                   | Purpose                      |

-
-### 2.4.4 Privacy & Sensitive Data Policy
-
-> **PII** = Personally Identifiable Information
-
-OpenTelemetry instrumentation is designed to collect **operational metadata only**, never sensitive content.
-
-#### Data NOT Collected
-
-The following data is explicitly **excluded** from telemetry collection:
-
-| Excluded Data           | Reason                                    |
-| ----------------------- | ----------------------------------------- |
-| **Private Keys**        | Never exposed; not relevant to tracing    |
-| **Account Balances**    | Financial data; privacy sensitive         |
-| **Transaction Amounts** | Financial data; privacy sensitive         |
-| **Raw TX Payloads**     | May contain sensitive memo/data fields    |
-| **Personal Data**       | No PII collected                          |
-| **IP Addresses**        | Configurable; excluded by default in prod |
-
-#### Privacy Protection Mechanisms
-
-| Mechanism                     | Description                                                               |
-| ----------------------------- | ------------------------------------------------------------------------- |
-| **Account Hashing**           | `xrpl.tx.account` is hashed at collector level before storage             |
-| **Configurable Redaction**    | Sensitive fields can be excluded via `[telemetry]` config section         |
-| **Sampling**                  | Only 10% of traces recorded by default, reducing data exposure            |
-| **Local Control**             | Node operators have full control over what gets exported                  |
-| **No Raw Payloads**           | Transaction content is never recorded, only metadata (hash, type, result) |
-| **Collector-Level Filtering** | Additional redaction/hashing can be configured at OTel Collector          |
-
-#### Collector-Level Data Protection
-
-The OpenTelemetry Collector can be configured to hash or redact sensitive attributes before export:
-
-```yaml
-processors:
-  attributes:
-    actions:
-      # Hash account addresses before storage
-      - key: xrpl.tx.account
-        action: hash
-      # Remove IP addresses entirely
-      - key: xrpl.peer.address
-        action: delete
-      # Redact specific fields
-      - key: xrpl.rpc.params
-        action: delete
-```
-
-#### Configuration Options for Privacy
-
-In `xrpld.cfg`, operators can control data collection granularity:
-
-```ini
-[telemetry]
-enabled=1
-
-# Disable collection of specific components
-trace_transactions=1
-trace_consensus=1
-trace_rpc=1
-trace_peer=0          # Disable peer tracing (high volume, includes addresses)
-
-# Redact specific attributes
-redact_account=1      # Hash account addresses before export
-redact_peer_address=1 # Remove peer IP addresses
-```
-
-> **Note**: The `redact_account` configuration in `xrpld.cfg` controls SDK-level redaction before export, while collector-level filtering (see [Collector-Level Data Protection](#collector-level-data-protection) above) provides an additional defense-in-depth layer. Both can operate independently.
-
-> **Key Principle**: Telemetry collects **operational metadata** (timing, counts, hashes) — never **sensitive content** (keys, balances, amounts, raw payloads).

-## 2.5 Context Propagation Design
-
-> **WS** = WebSocket
-
-### 2.5.1 Propagation Boundaries
-
-```mermaid
-flowchart TB
-    subgraph http["HTTP/WebSocket (RPC)"]
-        w3c["W3C Trace Context Headers:<br/>traceparent:<br/>00-trace_id-span_id-flags<br/>tracestate: xrpld=..."]
-    end
-
-    subgraph protobuf["Protocol Buffers (P2P)"]
-        proto["message TraceContext {<br/>  bytes trace_id = 1;  // 16 bytes<br/>  bytes span_id = 2;   // 8 bytes<br/>  uint32 trace_flags = 3;<br/>  string trace_state = 4;<br/>}"]
-    end
-
-    subgraph jobqueue["JobQueue (Internal Async)"]
-        job["Context captured at job creation,<br/>restored at execution<br/><br/>class Job {<br/>  otel::context::Context<br/>    traceContext_;<br/>};"]
-    end
-
-    style http fill:#0d47a1,stroke:#082f6a,color:#ffffff
-    style protobuf fill:#1b5e20,stroke:#0d3d14,color:#ffffff
-    style jobqueue fill:#bf360c,stroke:#8c2809,color:#ffffff
-```
-
-**Reading the diagram:**
-
-- **HTTP/WebSocket - RPC (blue)**: For client-facing RPC requests, trace context is propagated using the W3C `traceparent` header. This is the standard approach and works with any OTel-compatible client.
-- **Protocol Buffers - P2P (green)**: For peer-to-peer messages between xrpld nodes, trace context is embedded as a protobuf `TraceContext` message carrying trace_id, span_id, flags, and optional trace_state.
-- **JobQueue - Internal Async (red)**: For asynchronous work within a single node, the OTel context is captured when a job is created and restored when the job executes on a worker thread. This bridges the async gap so spans remain linked.
-

-
-## 2.6 Integration with Existing Observability
-
-> **OTLP** = OpenTelemetry Protocol | **WS** = WebSocket
-
-### 2.6.1 Existing Frameworks Comparison
-
-xrpld already has two observability mechanisms. OpenTelemetry complements (not replaces) them:
-
-| Aspect                | PerfLog                       | Beast Insight (StatsD)       | OpenTelemetry             |
-| --------------------- | ----------------------------- | ---------------------------- | ------------------------- |
-| **Type**              | Logging                       | Metrics                      | Distributed Tracing       |
-| **Data**              | JSON log entries              | Counters, gauges, histograms | Spans with context        |
-| **Scope**             | Single node                   | Single node                  | **Cross-node**            |
-| **Output**            | `perf.log` file               | StatsD server                | OTLP Collector            |
-| **Question answered** | "What happened on this node?" | "How many? How fast?"        | "What was the journey?"   |
-| **Correlation**       | By timestamp                  | By metric name               | By `trace_id`             |
-| **Overhead**          | Low (file I/O)                | Low (UDP packets)            | Low-Medium (configurable) |
-
-### 2.6.2 What Each Framework Does Best
-
-#### PerfLog
-
-- **Purpose**: Detailed local event logging for RPC and job execution
-- **Strengths**:
-  - Rich JSON output with timing data
-  - Already integrated in RPC handlers
-  - File-based, no external dependencies
-- **Limitations**:
-  - Single-node only (no cross-node correlation)
-  - No parent-child relationships between events
-  - Manual log parsing required
-
-```json
-// Example PerfLog entry
-{
-  "time": "2024-01-15T10:30:00.123Z",
-  "method": "submit",
-  "duration_us": 1523,
-  "result": "tesSUCCESS"
-}
-```
-
-#### Beast Insight (StatsD)
-
-- **Purpose**: Real-time metrics for monitoring dashboards
-- **Strengths**:
-  - Aggregated metrics (counters, gauges, histograms)
-  - Low overhead (UDP, fire-and-forget)
-  - Good for alerting thresholds
-- **Limitations**:
-  - No request-level detail
-  - No causal relationships
-  - Single-node perspective
-
-```cpp
-// Example StatsD usage in xrpld
-insight.increment("rpc.submit.count");
-insight.gauge("ledger.age", age);
-insight.timing("consensus.round", duration);
-```
-
-#### OpenTelemetry (NEW)
-
-- **Purpose**: Distributed request tracing across nodes
-- **Strengths**:
-  - **Cross-node correlation** via `trace_id`
-  - Parent-child span relationships
-  - Rich attributes per span
-  - Industry standard (CNCF)
-- **Limitations**:
-  - Requires collector infrastructure
-  - Higher complexity than logging
-
-```cpp
-// Example OpenTelemetry span
-auto span = telemetry.startSpan("tx.relay");
-span->SetAttribute("tx.hash", hash);
-span->SetAttribute("peer.id", peerId);
-// Span automatically linked to parent via context
-```
-
-### 2.6.3 When to Use Each
-
-| Scenario                                | PerfLog    | StatsD | OpenTelemetry |
-| --------------------------------------- | ---------- | ------ | ------------- |
-| "How many TXs per second?"              | ❌         | ✅     | ✅            |
-| "What's the p99 RPC latency?"           | ❌         | ✅     | ✅            |
-| "Why was this specific TX slow?"        | ⚠️ partial | ❌     | ✅            |
-| "Which node delayed consensus?"         | ❌         | ❌     | ✅            |
-| "What happened on node X at time T?"    | ✅         | ❌     | ✅            |
-| "Show me the TX journey across 5 nodes" | ❌         | ❌     | ✅            |
-
-### 2.6.4 Coexistence Strategy
-
-```mermaid
-flowchart TB
-    subgraph xrpld["xrpld Process"]
-        perflog["PerfLog<br/>(JSON to file)"]
-        insight["Beast Insight<br/>(StatsD)"]
-        otel["OpenTelemetry<br/>(Tracing)"]
-    end
-
-    perflog --> perffile["perf.log"]
-    insight --> statsd["StatsD Server"]
-    otel --> collector["OTLP Collector"]
-
-    perffile --> grafana["Grafana<br/>(Unified UI)"]
-    statsd --> grafana
-    collector --> grafana
-
-    style xrpld fill:#212121,stroke:#0a0a0a,color:#ffffff
-    style grafana fill:#bf360c,stroke:#8c2809,color:#ffffff
-```
-
-**Reading the diagram:**
-
-- **xrpld Process (dark gray)**: The single xrpld node running all three observability frameworks side by side. Each framework operates independently with no interference.
-- **PerfLog to perf.log**: PerfLog writes JSON-formatted event logs to a local file. Grafana can ingest these via Loki or a file-based datasource.
-- **Beast Insight to StatsD Server**: Insight sends aggregated metrics (counters, gauges) over UDP to a StatsD server. Grafana reads from StatsD-compatible backends like Graphite or Prometheus (via StatsD exporter).
-- **OpenTelemetry to OTLP Collector**: OTel exports spans over OTLP/gRPC to a Collector, which then forwards to a trace backend (Tempo).
-- **Grafana (red, unified UI)**: All three data streams converge in Grafana, enabling operators to correlate logs, metrics, and traces in a single dashboard.
-
-### 2.6.5 Correlation with PerfLog
-
-Trace IDs can be correlated with existing PerfLog entries for comprehensive debugging:
-
-```cpp
-// In RPCHandler.cpp - correlate trace with PerfLog
-Status doCommand(RPC::JsonContext& context, Json::Value& result)
-{
-    // Start OpenTelemetry span
-    auto span = context.app.getTelemetry().startSpan(
-        "rpc.command." + context.method);
-
-    // Get trace ID for correlation
-    auto traceId = span->GetContext().trace_id().IsValid()
-        ? toHex(span->GetContext().trace_id())
-        : "";
-
-    // Use existing PerfLog with trace correlation
-    auto const curId = context.app.getPerfLog().currentId();
-    context.app.getPerfLog().rpcStart(context.method, curId);
-
-    // Future: Add trace ID to PerfLog entry
-    // context.app.getPerfLog().setTraceId(curId, traceId);
-
-    try {
-        auto ret = handler(context, result);
-        context.app.getPerfLog().rpcFinish(context.method, curId);
-        span->SetStatus(opentelemetry::trace::StatusCode::kOk);
-        return ret;
-    } catch (std::exception const& e) {
-        context.app.getPerfLog().rpcError(context.method, curId);
-        span->RecordException(e);
-        span->SetStatus(opentelemetry::trace::StatusCode::kError, e.what());
-        throw;
-    }
-}

-### Key Principles
-
-1. **Minimal Intrusion**: Instrumentation should not alter existing control flow
-2. **Zero-Cost When Disabled**: Use compile-time flags and no-op implementations
-3. **Backward Compatibility**: Protocol Buffer extensions use high field numbers
-4. **Graceful Degradation**: Tracing failures must not affect node operation

-
-| Metric        | Overhead   | Notes                                            |
-| ------------- | ---------- | ------------------------------------------------ |
-| CPU           | 1-3%       | Of per-transaction CPU cost (~200μs baseline)    |
-| Memory        | ~10 MB     | SDK statics + batch buffer + worker thread stack |
-| Network       | 10-50 KB/s | Compressed OTLP export to collector              |
-| Latency (p99) | <2%        | With proper sampling configuration               |

-## 3.4 Detailed CPU Overhead Analysis
-
-### 3.4.1 Per-Operation Costs
-
-> **Note on hardware assumptions**: The costs below are based on the official OTel C++ SDK CI benchmarks
-> (969 runs on GitHub Actions 2-core shared runners). On production server hardware (3+ GHz Xeon),
-> expect costs at the **lower end** of each range (~30-50% improvement over CI hardware).
-
-| Operation             | Time (ns) | Frequency              | Impact     |
-| --------------------- | --------- | ---------------------- | ---------- |
-| Span creation         | 500-1000  | Every traced operation | Low        |
-| Span end              | 100-200   | Every traced operation | Low        |
-| SetAttribute (string) | 80-120    | 3-5 per span           | Low        |
-| SetAttribute (int)    | 40-60     | 2-3 per span           | Negligible |
-| AddEvent              | 100-200   | 0-2 per span           | Low        |
-| Context injection     | 150-250   | Per outgoing message   | Low        |
-| Context extraction    | 100-180   | Per incoming message   | Low        |
-| GetCurrent context    | 10-20     | Thread-local access    | Negligible |
-
-**Source**: Span creation based on OTel C++ SDK `BM_SpanCreation` benchmark (AlwaysOnSampler +
-SimpleSpanProcessor + InMemoryExporter), median ~1,000 ns on CI hardware. AddEvent includes
-timestamp read + string copy + vector push + mutex acquisition. Context injection/extraction
-confirmed by `BM_SpanCreationWithScope` benchmark delta (~160 ns).
-
-### 3.4.2 Transaction Processing Overhead
-
-<div align="center">
-
-```mermaid
-%%{init: {'pie': {'textPosition': 0.75}}}%%
-pie showData
-    "tx.receive (1400ns)" : 1400
-    "tx.validate (1200ns)" : 1200
-    "tx.relay (1200ns)" : 1200
-    "Context inject (200ns)" : 200
-```
-
-**Transaction Tracing Overhead (~4.0μs total)**
-
-</div>
-
-**Overhead percentage**: 4.0 μs / 200 μs (avg tx processing) = **~2.0%**
-
-> **Breakdown**: Each span (tx.receive, tx.validate, tx.relay) costs ~1,000 ns for creation plus
-> ~200-400 ns for 3-5 attribute sets. Context injection is ~200 ns (confirmed by benchmarks).
-> On production hardware, expect ~2.6 μs total (~1.3% overhead) due to faster span creation (~500-600 ns).
-
-### 3.4.3 Consensus Round Overhead
-
-| Operation              | Count | Cost (ns) | Total      |
-| ---------------------- | ----- | --------- | ---------- |
-| consensus.round span   | 1     | ~1200     | ~1.2 μs    |
-| consensus.phase spans  | 3     | ~1100     | ~3.3 μs    |
-| proposal.receive spans | ~20   | ~1100     | ~22 μs     |
-| proposal.send spans    | ~3    | ~1100     | ~3.3 μs    |
-| Context operations     | ~30   | ~200      | ~6 μs      |
-| **TOTAL**              |       |           | **~36 μs** |
-
-> **Why higher**: Each span costs ~1,000 ns creation + ~100-200 ns for 1-2 attributes, totaling ~1,100-1,200 ns.
-> Context operations remain ~200 ns (confirmed by benchmarks). On production hardware, expect ~24 μs total.
-
-**Overhead percentage**: 36 μs / 3s (typical round) = **~0.001%** (negligible)
-
-### 3.4.4 RPC Request Overhead
-
-| Operation        | Cost (ns)    |
-| ---------------- | ------------ |
-| rpc.request span | ~1200        |
-| rpc.command span | ~1100        |
-| Context extract  | ~250         |
-| Context inject   | ~200         |
-| **TOTAL**        | **~2.75 μs** |
-
-> **Why higher**: Each span costs ~1,000 ns creation + ~100-200 ns for attributes (command name,
-> version, role). Context extract/inject costs are confirmed by OTel C++ benchmarks.
-
-- Fast RPC (1ms): 2.75 μs / 1ms = **~0.275%**
-- Slow RPC (100ms): 2.75 μs / 100ms = **~0.003%**

-## 3.5 Memory Overhead Analysis
-
-> **OTLP** = OpenTelemetry Protocol
-
-### 3.5.1 Static Memory
-
-| Component                            | Size        | Allocated  |
-| ------------------------------------ | ----------- | ---------- |
-| TracerProvider singleton             | ~64 KB      | At startup |
-| BatchSpanProcessor (circular buffer) | ~16 KB      | At startup |
-| BatchSpanProcessor (worker thread)   | ~8 MB       | At startup |
-| OTLP exporter (gRPC channel init)    | ~256 KB     | At startup |
-| Propagator registry                  | ~8 KB       | At startup |
-| **Total static**                     | **~8.3 MB** |            |
-
-> **Why higher than earlier estimate**: The BatchSpanProcessor's circular buffer itself is only ~16 KB
-> (2049 x 8-byte `AtomicUniquePtr` entries), but it spawns a dedicated worker thread whose default
-> stack size on Linux is ~8 MB. The OTLP gRPC exporter allocates memory for channel stubs and TLS
-> initialization. The worker thread stack dominates the static footprint.
-
-### 3.5.2 Dynamic Memory
-
-| Component            | Size per unit  | Max units  | Peak            |
-| -------------------- | -------------- | ---------- | --------------- |
-| Active span          | ~500-800 bytes | 1000       | ~500-800 KB     |
-| Queued span (export) | ~500 bytes     | 2048       | ~1 MB           |
-| Attribute storage    | ~80 bytes      | 5 per span | Included        |
-| Context storage      | ~64 bytes      | Per thread | ~6.4 KB         |
-| **Total dynamic**    |                |            | **~1.5-1.8 MB** |
-
-> **Why active spans are larger**: An active `Span` object includes the wrapper (~88 bytes: shared_ptr,
-> mutex, unique_ptr to Recordable) plus `SpanData` (~250 bytes: SpanContext, timestamps, name, status,
-> empty containers) plus attribute storage (~200-500 bytes for 3-5 string attributes in a `std::map`).
-> Source: `sdk/src/trace/span.h` and `sdk/include/opentelemetry/sdk/trace/span_data.h`.
-> Queued spans release the wrapper, keeping only `SpanData` + attributes (~500 bytes).

-```
-
-**Notes**:
-
-- Memory increases with span rate but **plateaus at queue capacity** (default 2048 spans)
-- Batch export prevents unbounded growth
-- At queue limit, oldest spans are dropped (not blocked)
-- Maximum memory is bounded: ~8.3 MB static (dominated by worker thread stack) + 2048 queued spans x ~500 bytes (~1 MB) + active spans (~0.8 MB) ≈ **~10 MB ceiling**
-- The worker thread stack (~8 MB) is virtual memory; actual RSS depends on stack usage (typically much less)

-## 3.6 Network Overhead Analysis
-
-### 3.6.1 Export Bandwidth
-
-> **Bytes per span**: Estimates use ~500 bytes/span (conservative upper bound). OTLP protobuf analysis
-> shows a typical span with 3-5 string attributes serializes to ~200-300 bytes raw; with gzip
-> compression (~60-70% of raw) and batching (amortized headers), ~350 bytes/span is more realistic.
-> The table uses the conservative estimate for capacity planning.
-
-| Sampling Rate | Spans/sec | Bandwidth | Notes            |
-| ------------- | --------- | --------- | ---------------- |
-| 100%          | ~500      | ~250 KB/s | Development only |
-| 10%           | ~50       | ~25 KB/s  | Staging          |
-| 1%            | ~5        | ~2.5 KB/s | Production       |
-| Error-only    | ~1        | ~0.5 KB/s | Minimal overhead |
-
-### 3.6.2 Trace Context Propagation
-
-| Message Type           | Context Size | Messages/sec | Overhead    |
-| ---------------------- | ------------ | ------------ | ----------- |
-| TMTransaction          | 25 bytes     | ~100         | ~2.5 KB/s   |
-| TMProposeSet           | 25 bytes     | ~10          | ~250 B/s    |

-| Risk Level | Definition                                                       | Mitigation                         |
-| ---------- | ---------------------------------------------------------------- | ---------------------------------- |
-| **Low**    | Additive changes only; no modification to existing logic         | Standard code review               |
-| **Medium** | Minor modifications to existing functions; clear boundaries      | Comprehensive unit tests           |
-| **High**   | Changes to core logic or data structures; potential side effects | Integration tests + staged rollout |
-
-### 3.9.4 Architectural Impact Assessment
-
-| Aspect               | Impact  | Justification                                                                    |
-| -------------------- | ------- | -------------------------------------------------------------------------------- |
-| **Data Flow**        | Minimal | Read-only instrumentation; no modification to consensus or transaction data flow |
-| **Threading Model**  | Minimal | Context propagation uses thread-local storage (standard OTel pattern)            |
-| **Memory Model**     | Low     | Bounded queues prevent unbounded growth; RAII ensures cleanup                    |
-| **Network Protocol** | Low     | Optional fields in protobuf (high field numbers); backward compatible            |
-| **Configuration**    | None    | New config section; existing configs unaffected                                  |
-| **Build System**     | Low     | Optional CMake flag; builds work without OpenTelemetry                           |
-| **Dependencies**     | Low     | OpenTelemetry SDK is optional; null implementation when disabled                 |
-
-### 3.9.5 Backward Compatibility
-
-| Compatibility   | Status  | Notes                                                 |
-| --------------- | ------- | ----------------------------------------------------- |
-| **Config File** | ✅ Full | New `[telemetry]` section is optional                 |
-| **Protocol**    | ✅ Full | Optional protobuf fields with high field numbers      |
-| **Build**       | ✅ Full | `XRPL_ENABLE_TELEMETRY=OFF` produces identical binary |
-| **Runtime**     | ✅ Full | `enabled=0` produces zero overhead                    |
-| **API**         | ✅ Full | No changes to public RPC or P2P APIs                  |
-
-### 3.9.6 Rollback Strategy
-
-If issues are discovered after deployment:
-
-1. **Immediate**: Set `enabled=0` in config and restart (zero code change)
-2. **Quick**: Rebuild with `XRPL_ENABLE_TELEMETRY=OFF`
-3. **Complete**: Revert telemetry commits (clean separation makes this easy)
-
-### 3.9.7 Code Change Examples
-
-**Minimal RPC Instrumentation (Low Intrusiveness):**
-
-```cpp
-// Before
-void ServerHandler::onRequest(...) {
-    auto result = processRequest(req);
-    send(result);
-}
-
-// After (only ~10 lines added)
-void ServerHandler::onRequest(...) {
-    XRPL_TRACE_RPC(app_.getTelemetry(), "rpc.request");  // +1 line
-    XRPL_TRACE_SET_ATTR("xrpl.rpc.command", command);     // +1 line
-
-    auto result = processRequest(req);
-
-    XRPL_TRACE_SET_ATTR("xrpl.rpc.status", status);       // +1 line
-    send(result);
-}
-```
-
-**Consensus Instrumentation (Medium Intrusiveness):**
-
-```cpp
-// Before
-void RCLConsensusAdaptor::startRound(...) {
-    // ... existing logic
-}
-
-// After (context storage required)
-void RCLConsensusAdaptor::startRound(...) {
-    XRPL_TRACE_CONSENSUS(app_.getTelemetry(), "consensus.round");
-    XRPL_TRACE_SET_ATTR("xrpl.consensus.ledger.seq", seq);
-
-    // Store context for child spans in phase transitions
-    currentRoundContext_ = _xrpl_guard_->context();  // New member variable
-
-    // ... existing logic unchanged
-}
-```

-## 5.3 Application Integration
-
-### 5.3.1 ApplicationImp Changes
-
-> **Deferred identity**: The node public key (`nodeIdentity_`) is not
-> available during `ApplicationImp`'s member initializer list — it is
-> resolved later in `setup()`. The `Telemetry` object is therefore
-> constructed with an empty `serviceInstanceId` and patched via
-> `setServiceInstanceId()` once `setup()` has called `getNodeIdentity()`.
-
-```cpp
-// src/xrpld/app/main/Application.cpp (modified)
-
-#include <xrpl/telemetry/Telemetry.h>
-
-class ApplicationImp : public Application, public BasicApp
-{
-    // ... existing members (perfLog_, etc.) ...
-
-    // Telemetry — constructed in the member initializer list with
-    // an empty serviceInstanceId, patched in setup().
-    std::unique_ptr<telemetry::Telemetry> telemetry_;
-
-    // Member initializer list (excerpt):
-    // ...
-    // , telemetry_(
-    //       telemetry::make_Telemetry(
-    //           telemetry::setup_Telemetry(
-    //               config_->section("telemetry"),
-    //               "",  // Updated later via setServiceInstanceId()
-    //               BuildInfo::getVersionString()),
-    //           logs_->journal("Telemetry")))
-    // ...
-
-    bool setup(...) override
-    {
-        // ... existing setup code ...
-
-        nodeIdentity_ = getNodeIdentity(*this, cmdline);
-
-        // Inject node identity into telemetry resource attributes,
-        // unless the user already set a custom service_instance_id.
-        if (!config_->section("telemetry").exists("service_instance_id"))
-            telemetry_->setServiceInstanceId(
-                toBase58(TokenType::NodePublic, nodeIdentity_->first));
-
-        // ... rest of setup ...
-    }
-
-    void start(bool withTimers) override
-    {
-        // ... existing start code ...
-        telemetry_->start();
-    }
-
-    void run() override
-    {
-        // ... existing run/shutdown code ...
-        telemetry_->stop();
-    }
-
-    telemetry::Telemetry&
-    getTelemetry() override
-    {
-        return *telemetry_;
-    }
-};
-```
-
-### 5.3.2 ServiceRegistry Interface Addition
-
-```cpp
-// include/xrpl/core/ServiceRegistry.h (modified)
-
-namespace telemetry {
-class Telemetry;
-}  // namespace telemetry
-
-class ServiceRegistry
-{
-public:
-    // ... existing virtual methods ...
-
-    /** Get the telemetry system for distributed tracing. */
-    virtual telemetry::Telemetry&
-    getTelemetry() = 0;
-};
-```
-
-> **Note:** `Application` extends `ServiceRegistry`, so `getTelemetry()` is
-> available on both. Components that hold a `ServiceRegistry&` (e.g.
-> `NetworkOPsImp`) call `registry_.get().getTelemetry()`. Components that
-> still hold an `Application&` (e.g. `ServerHandler`, `PeerImp`,
-> `RCLConsensusAdaptor`) call `app_.getTelemetry()` directly.

-**Reading the diagram:**
-
-- **Configuration Sources**: `xrpld.cfg` provides runtime settings (endpoint, sampling) while the CMake flag controls whether telemetry is compiled in at all.
-- **Initialization**: `setup_Telemetry()` parses config values, then `make_Telemetry()` constructs the provider, processor, and exporter objects.
-- **Runtime Components**: The `TracerProvider` creates spans, the `BatchProcessor` buffers them, and the `OTLP Exporter` serializes and sends them over the wire.
-- **OTLP arrow to Collector**: Trace data leaves the xrpld process via OTLP (gRPC or HTTP) and enters the external Collector pipeline.
-- **Collector Pipeline**: `Receivers` ingest OTLP data, `Processors` apply sampling/filtering/enrichment, and `Exporters` forward traces to storage backends (Tempo, etc.).

-
-### 5.8.5 TraceQL Query Examples
-
-Common queries for xrpld traces:
-
-```
-# Find all traces for a specific transaction hash
-{resource.service.name="xrpld" && span.xrpl.tx.hash="ABC123..."}
-
-# Find slow RPC commands (>100ms)
-{resource.service.name="xrpld" && name=~"rpc.command.*"} | duration > 100ms
-
-# Find consensus rounds taking >5 seconds
-{resource.service.name="xrpld" && name="consensus.round"} | duration > 5s
-
-# Find failed transactions with error details
-{resource.service.name="xrpld" && name="tx.validate" && status.code=error}
-
-# Find transactions relayed to many peers
-{resource.service.name="xrpld" && name="tx.relay"} | span.xrpl.tx.relay_count > 10
-
-# Compare latency across nodes
-{resource.service.name="xrpld" && name="rpc.command.account_info"} | avg(duration) by (resource.service.instance.id)
-```
-
-### 5.8.6 Correlation with PerfLog
-
-To correlate OpenTelemetry traces with existing PerfLog data:
-
-**Step 1: Configure Loki to ingest PerfLog**
-
-```yaml
-# promtail-config.yaml
-scrape_configs:
-  - job_name: xrpld-perflog
-    static_configs:
-      - targets:
-          - localhost
-        labels:
-          job: xrpld
-          __path__: /var/log/rippled/perf*.log
-    pipeline_stages:
-      - json:
-          expressions:
-            trace_id: trace_id
-            ledger_seq: ledger_seq
-            tx_hash: tx_hash
-      - labels:
-          trace_id:
-          ledger_seq:
-          tx_hash:
-```
-
-**Step 2: Add trace_id to PerfLog entries**
-
-Modify PerfLog to include trace_id when available:
-
-```cpp
-// In PerfLog output, add trace_id from current span context
-void logPerf(Json::Value& entry) {
-    auto span = opentelemetry::trace::GetSpan(
-        opentelemetry::context::RuntimeContext::GetCurrent());
-    if (span && span->GetContext().IsValid()) {
-        char traceIdHex[33];
-        span->GetContext().trace_id().ToLowerBase16(traceIdHex);
-        entry["trace_id"] = std::string(traceIdHex, 32);
-    }
-    // ... existing logging
-}
-```
-
-**Step 3: Configure Grafana trace-to-logs link**
-
-In Tempo data source configuration, set up the derived field:
-
-```yaml
-jsonData:
-  tracesToLogs:
-    datasourceUid: loki
-    tags: ["trace_id", "xrpl.tx.hash"]
-    filterByTraceID: true
-    filterBySpanID: false
-```
-
-### 5.8.7 Correlation with Insight/StatsD Metrics
-
-To correlate traces with existing Beast Insight metrics:
-
-**Step 1: Export Insight metrics to Prometheus**
-
-```yaml
-# prometheus.yaml
-scrape_configs:
-  - job_name: "xrpld-statsd"
-    static_configs:
-      - targets: ["statsd-exporter:9102"]
-```
-
-**Step 2: Add exemplars to metrics**
-
-OpenTelemetry SDK automatically adds exemplars (trace IDs) to metrics when using the Prometheus exporter. This links metrics spikes to specific traces.
-
-**Step 3: Configure Grafana metric-to-trace link**
-
-```yaml
-# In Prometheus data source
-jsonData:
-  exemplarTraceIdDestinations:
-    - name: trace_id
-      datasourceUid: tempo
-```
-
-**Step 4: Dashboard panel with exemplars**
-
-```json
-{
-  "title": "RPC Latency with Trace Links",
-  "type": "timeseries",
-  "datasource": "Prometheus",
-  "targets": [
-    {
-      "expr": "histogram_quantile(0.99, rate(xrpld_rpc_duration_seconds_bucket[5m]))",
-      "exemplar": true
-    }
-  ]
-}
-```
-
-This allows clicking on metric data points to jump directly to the related trace.

-
-Phase 4a (establish-phase gap fill & cross-node correlation) adds:
-
-- **Deterministic trace ID** derived from `previousLedger.id()` so all validators
-  in the same round share the same `trace_id` (switchable via
-  `consensus_trace_strategy` config: `"deterministic"` or `"attribute"`).
-  See [Configuration Reference](./05-configuration-reference.md) for full
-  configuration options. The `consensus_trace_strategy` option will be
-  documented in the configuration reference as part of Phase 4a implementation.
-- **Round lifecycle spans**: `consensus.round` with round-to-round span links.
-- **Establish phase**: `consensus.establish`, `consensus.update_positions` (with
-  `dispute.resolve` events), `consensus.check` (with threshold tracking).
-- **Mode changes**: `consensus.mode_change` spans.
-- **Validation**: `consensus.validation.send` with span link to round span
-  (thread-safe cross-thread access via `roundSpanContext_` snapshot).
-- **Separation of concerns**: telemetry extracted to private helpers
-  (`startRoundTracing`, `createValidationSpan`, `startEstablishTracing`,
-  `updateEstablishTracing`, `endEstablishTracing`).

-**Reading the diagram:**
-
-- **CRAWL (Weeks 1-2)**: Minimal investment -- set up the SDK, instrument RPC and PathFinding/TxQ handlers, and verify on a single node. Delivers immediate latency visibility.
-- **WALK (Weeks 3-5)**: Expand to transaction lifecycle tracing, fee escalation, cross-node context propagation, and basic Grafana dashboards. This is where distributed tracing starts working.
-- **RUN (Weeks 6-9)**: Full consensus instrumentation, validator/amendment/SHAMap tracing, end-to-end correlation, and production deployment with sampling and alerting.
-- **Arrows (crawl → walk → run)**: Each phase builds on the prior one; you cannot skip ahead because later phases depend on infrastructure established earlier.
-
-### 6.9.2 Quick Wins (Immediate Value)
-
-| Quick Win                      | Value  | When to Deploy |
-| ------------------------------ | ------ | -------------- |
-| **RPC Command Tracing**        | High   | Week 2         |
-| **RPC Latency Histograms**     | High   | Week 2         |
-| **Error Rate Dashboard**       | Medium | Week 2         |
-| **Transaction Submit Tracing** | High   | Week 3         |
-| **Consensus Round Duration**   | Medium | Week 6         |
-
-### 6.9.3 CRAWL Phase (Weeks 1-2)
-
-**Goal**: Get basic tracing working with minimal code changes.
-
-**What You Get**:
-
-- RPC request/response traces for all commands
-- Latency breakdown per RPC command
-- PathFinding and TxQ tracing (directly impacts RPC latency)
-- Error visibility with stack traces
-- Basic Grafana dashboard
-
-**Code Changes**: ~15 lines in `ServerHandler.cpp`, ~40 lines in new telemetry module
-
-**Why Start Here**:
-
-- RPC is the lowest-risk, highest-visibility component
-- PathFinding and TxQ are RPC-adjacent and directly affect latency
-- Immediate value for debugging client issues
-- No cross-node complexity
-- Single file modification to existing code
-
-### 6.9.4 WALK Phase (Weeks 3-5)
-
-**Goal**: Add transaction lifecycle tracing across nodes.
-
-**What You Get**:
-
-- End-to-end transaction traces from submit to relay
-- Fee escalation tracing within the transaction pipeline
-- Cross-node correlation (see transaction path)
-- HashRouter deduplication visibility
-- Relay latency metrics
-
-**Code Changes**: ~120 lines across 4 files, plus protobuf extension
-
-**Why Do This Second**:
-
-- Builds on RPC tracing (transactions submitted via RPC)
-- Fee escalation is integral to the transaction processing pipeline
-- Moderate complexity (requires context propagation)
-- High value for debugging transaction issues
-
-### 6.9.5 RUN Phase (Weeks 6-9)
-
-**Goal**: Full observability including consensus.
-
-**What You Get**:
-
-- Complete consensus round visibility
-- Phase transition timing
-- Validator proposal tracking
-- Validator list and manifest tracing
-- Amendment voting tracing
-- SHAMap sync tracing
-- Full end-to-end traces (client → RPC → TX → consensus → ledger)
-
-**Code Changes**: ~100 lines across 3 consensus files, plus validator/amendment/SHAMap modules
-
-**Why Do This Last**:
-
-- Highest complexity (consensus is critical path)
-- Validator, amendment, and SHAMap components are lower priority
-- Requires thorough testing
-- Lower relative value (consensus issues are rarer)

-**Reading the diagram:**
-
-- **Week 1 (tasks 1-2)**: Foundation work -- integrate the OpenTelemetry SDK via Conan/CMake and build the `Telemetry` interface with `SpanGuard` and config parsing.
-- **Week 2 (tasks 3-4)**: First observable output -- instrument `ServerHandler` for RPC tracing and stand up Tempo so developers can see traces immediately.
-- **Weeks 3-5 (tasks 5-10)**: Transaction lifecycle -- add submit tracing, build the first Grafana dashboard, extend protobuf for cross-node context, instrument `PeerImp` relay, then validate with multi-node integration tests and performance benchmarks.
-- **Weeks 6-8 (tasks 11-12)**: Consensus deep-dive -- instrument consensus rounds and phases, then run full integration testing across all instrumented paths.
-- **Week 9 (tasks 13-14)**: Go-live -- deploy to production with sampling/alerting configured, and deliver documentation and operator training.
-- **Arrow chain (t1 → ... → t14)**: Strict sequential dependency; each task's output is a prerequisite for the next.

-**Reading the diagram:**
-
-- **Budget Constraints? (Yes)**: Leads to open-source options. If you already run Grafana or Elastic, pick the matching backend; otherwise default to Grafana Tempo.
-- **Budget Constraints? (No) → Prefer SaaS?**: If you want a managed service, choose between Datadog (enterprise support) and Honeycomb (developer-focused). If not, fall back to open-source.
-- **Terminal nodes (Tempo / Elastic / Honeycomb / Datadog)**: Each represents a concrete backend choice, all of which feed into the same final step.
-- **Configure Collector**: Regardless of backend, you always finish by configuring the OTel Collector to export to your chosen destination.

-
-**Reading the diagram:**
-
-- **Validator / Stock Nodes**: All xrpld nodes emit trace data via OTLP. Validators and stock nodes are grouped separately because they may reside in different network zones.
-- **Collector Cluster (DC1, DC2)**: Regional collectors receive OTLP from nodes in their datacenter, apply processing (sampling, enrichment), and fan out to multiple backends.
-- **Storage Backends**: Tempo and Elastic provide queryable trace storage; S3/GCS Archive provides long-term cold storage for compliance or post-incident analysis.
-- **Grafana Dashboards**: The single visualization layer that queries both Tempo and Elastic, giving operators a unified view of all traces.
-- **Data flow direction**: Nodes → Collectors → Storage → Grafana. Each arrow represents a network hop; minimizing collector-to-backend hops reduces latency.
-
-> **Note**: Production deployments should use multiple collector instances behind a load balancer for high availability. The diagram shows a simplified single-collector topology for clarity.

-## 7.4 Architecture Considerations
-
-### 7.4.1 Collector Placement
-
-| Strategy      | Description          | Pros                     | Cons                    |
-| ------------- | -------------------- | ------------------------ | ----------------------- |
-| **Sidecar**   | Collector per node   | Isolation, simple config | Resource overhead       |
-| **DaemonSet** | Collector per host   | Shared resources         | Complexity              |
-| **Gateway**   | Central collector(s) | Centralized processing   | Single point of failure |
-
-**Recommendation**: Use **Gateway** pattern with regional collectors for xrpld networks:
-
-- One collector cluster per datacenter/region
-- Tail-based sampling at collector level
-- Multiple export destinations for redundancy
-
-### 7.4.2 Sampling Strategy
-
-```mermaid
-flowchart LR
-    subgraph head["Head Sampling (Node)"]
-        hs[Node-level head sampling<br/>configurable, default: 100%<br/>recommended production: 10%]
-    end
-
-    subgraph tail["Tail Sampling (Collector)"]
-        ts1[Keep all errors]
-        ts2[Keep slow >5s]
-        ts3[Keep 10% rest]
-    end
-
-    head --> tail
-
-    ts1 --> final[Final Traces]
-    ts2 --> final
-    ts3 --> final
-
-    style head fill:#0d47a1,stroke:#082f6a,color:#fff
-    style tail fill:#1b5e20,stroke:#0d3d14,color:#fff
-    style hs fill:#0d47a1,stroke:#082f6a,color:#fff
-    style ts1 fill:#1b5e20,stroke:#0d3d14,color:#fff
-    style ts2 fill:#1b5e20,stroke:#0d3d14,color:#fff
-    style ts3 fill:#1b5e20,stroke:#0d3d14,color:#fff
-    style final fill:#bf360c,stroke:#8c2809,color:#fff
-```
-
-**Reading the diagram:**
-
-- **Head Sampling (Node)**: The first filter -- each xrpld node decides whether to sample a trace at creation time (default 100%, recommended 10% in production). This controls the volume leaving the node.
-- **Tail Sampling (Collector)**: The second filter -- the collector inspects completed traces and applies rules: keep all errors, keep anything slower than 5 seconds, and keep 10% of the remainder.
-- **Arrow head → tail**: All head-sampled traces flow to the collector, where tail sampling further reduces volume while preserving the most valuable data.
-- **Final Traces**: The output after both sampling stages; this is what gets stored and queried. The two-stage approach balances cost with debuggability.
-
-### 7.4.3 Data Retention
-
-| Environment | Hot Storage | Warm Storage | Cold Archive |
-| ----------- | ----------- | ------------ | ------------ |
-| Development | 24 hours    | N/A          | N/A          |
-| Staging     | 7 days      | N/A          | N/A          |
-| Production  | 7 days      | 30 days      | many years   |

-**Reading the diagram:**
-
-- **xrpld Node (three sources)**: A single node emits three independent data streams -- OpenTelemetry spans, PerfLog JSON logs, and Beast Insight StatsD metrics.
-- **Data Collection layer**: Each stream has its own collector -- OTel Collector for spans, Promtail/Fluentd for logs, and a StatsD exporter for metrics. They operate independently.
-- **Storage layer (Tempo, Loki, Prometheus)**: Each data type lands in a purpose-built store optimized for its query patterns (trace search, log grep, metric aggregation).
-- **Grafana Correlation Panel**: The key integration point -- Grafana queries all three stores and links them via shared fields (`trace_id`, `xrpl.tx.hash`, `ledger_seq`), enabling a single-pane debugging experience.
-
-### 7.7.2 Correlation Fields
-
-| Source      | Field                       | Link To       | Purpose                    |
-| ----------- | --------------------------- | ------------- | -------------------------- |
-| **Trace**   | `trace_id`                  | Logs          | Find log entries for trace |
-| **Trace**   | `xrpl.tx.hash`              | Logs, Metrics | Find TX-related data       |
-| **Trace**   | `xrpl.consensus.ledger.seq` | Logs          | Find ledger-related logs   |
-| **PerfLog** | `trace_id` (new)            | Traces        | Jump to trace from log     |
-| **PerfLog** | `ledger_seq`                | Traces        | Find consensus trace       |
-| **Insight** | `exemplar.trace_id`         | Traces        | Jump from metric spike     |
-
-### 7.7.3 Example: Debugging a Slow Transaction
-
-**Step 1: Find the trace**
-
-```
-# In Grafana Explore with Tempo
-{resource.service.name="xrpld" && span.xrpl.tx.hash="ABC123..."}
-```
-
-**Step 2: Get the trace_id from the trace view**
-
-```
-Trace ID: 4bf92f3577b34da6a3ce929d0e0e4736
-```
-
-**Step 3: Find related PerfLog entries**
-
-```
-# In Grafana Explore with Loki
-{job="xrpld"} |= "4bf92f3577b34da6a3ce929d0e0e4736"
-```
-
-**Step 4: Check Insight metrics for the time window**
-
-```
-# In Grafana with Prometheus
-rate(xrpld_tx_applied_total[1m])
-  @ timestamp_from_trace
-```

-**Reading the diagram:**
-
-- **rpc.request (blue, top)**: The entry point — every traced transaction starts as an RPC call; this root span is the parent of all downstream work.
-- **tx.validate and pathfind.request (green/teal, first fork)**: The RPC request fans out into transaction validation and, for cross-currency payments, a PathFinding branch (`pathfind.request` -> `pathfind.compute`).
-- **tx.relay -> Peer Spans (teal, middle)**: After validation, the transaction is relayed to peers A, B, and C in parallel; each `peer.send` is a sibling child span showing fan-out across the network.
-- **context propagation (dashed arrow)**: The dotted line from `peer.send Peer A` to `consensus.round` represents the trace context crossing a node boundary — the receiving validator picks up the same `trace_id` and continues the trace.
-- **consensus.round -> tx.apply -> TxQ Spans (green, lower)**: Once consensus accepts the transaction, it is applied to the ledger; the TxQ spans (`txq.enqueue`, `txq.apply`, `fee.escalate`) capture queue depth and fee escalation behavior.
-- **Validator Spans (purple, detached)**: `validator.list.fetch` and `validator.manifest` are independent workflows for UNL management — they run on their own traces and are linked to consensus via Span Links, not parent-child relationships.

-# [OpenTelemetry](00-tracing-fundamentals.md) Distributed Tracing Implementation Plan for xrpld (xrpld)
-
-## Executive Summary
-
-> **OTLP** = OpenTelemetry Protocol
-
-This document provides a comprehensive implementation plan for integrating OpenTelemetry distributed tracing into the xrpld XRP Ledger node software. The plan addresses the unique challenges of a decentralized peer-to-peer system where trace context must propagate across network boundaries between independent nodes.
-
-### Key Benefits
-
-- **End-to-end transaction visibility**: Track transactions from submission through consensus to ledger inclusion
-- **Consensus round analysis**: Understand timing and behavior of consensus phases across validators
-- **RPC performance insights**: Identify slow handlers and optimize response times
-- **Network topology understanding**: Visualize message propagation patterns between peers
-- **Incident debugging**: Correlate events across distributed nodes during issues
-
-### Estimated Performance Overhead
-
-| Metric        | Overhead   | Notes                               |
-| ------------- | ---------- | ----------------------------------- |
-| CPU           | 1-3%       | Span creation and attribute setting |
-| Memory        | 2-5 MB     | Batch buffer for pending spans      |
-| Network       | 10-50 KB/s | Compressed OTLP export to collector |
-| Latency (p99) | <2%        | With proper sampling configuration  |

-## 0. Tracing Fundamentals
-
-This document introduces distributed tracing concepts for readers unfamiliar with the domain. It covers what traces and spans are, how parent-child and follows-from relationships model causality, how context propagates across service boundaries, and how sampling controls data volume. It also maps these concepts to xrpld-specific scenarios like transaction relay and consensus.
-

-
-## 1. Architecture Analysis
-
-> **WS** = WebSocket | **TxQ** = Transaction Queue
-
-The xrpld node consists of several key components that require instrumentation for comprehensive distributed tracing. The main areas include the RPC server (HTTP/WebSocket), Overlay P2P network, Consensus mechanism (RCLConsensus), JobQueue for async task execution, PathFinding, Transaction Queue (TxQ), fee escalation (LoadManager), ledger acquisition, validator management, and existing observability infrastructure (PerfLog, Insight/StatsD, Journal logging).
-
-Key trace points span across transaction submission via RPC, peer-to-peer message propagation, consensus round execution, ledger building, path computation, transaction queue behavior, fee escalation, and validator health. The implementation prioritizes high-value, low-risk components first: RPC handlers provide immediate value with minimal risk, while consensus tracing requires careful implementation to avoid timing impacts.
-
-➡️ **[Read full Architecture Analysis](./01-architecture-analysis.md)**
-
----
-
-## 2. Design Decisions
-
-> **OTLP** = OpenTelemetry Protocol | **CNCF** = Cloud Native Computing Foundation
-
-The OpenTelemetry C++ SDK is selected for its CNCF backing, active development, and native performance characteristics. Traces are exported via OTLP/gRPC (primary) or OTLP/HTTP (fallback) to an OpenTelemetry Collector, which provides flexible routing and sampling.
-
-Span naming follows a hierarchical `<component>.<operation>` convention (e.g., `rpc.submit`, `tx.relay`, `consensus.round`). Context propagation uses W3C Trace Context headers for HTTP and embedded Protocol Buffer fields for P2P messages. The implementation coexists with existing PerfLog and Insight observability systems through correlation IDs.
-
-**Data Collection & Privacy**: Telemetry collects only operational metadata (timing, counts, hashes) — never sensitive content (private keys, balances, amounts, raw payloads). Privacy protection includes account hashing, configurable redaction, sampling, and collector-level filtering. Node operators retain full control over telemetry configuration.
-
-➡️ **[Read full Design Decisions](./02-design-decisions.md)**
-
----
-
-## 3. Implementation Strategy
-
-The telemetry code is organized under `include/xrpl/telemetry/` for headers and `src/libxrpl/telemetry/` for implementation. Key principles include RAII-based span management via `SpanGuard`, conditional compilation with `XRPL_ENABLE_TELEMETRY`, and minimal runtime overhead through batch processing and efficient sampling.
-
-Performance optimization strategies include probabilistic head sampling (10% default), tail-based sampling at the collector for errors and slow traces, batch export to reduce network overhead, and conditional instrumentation that compiles to no-ops when disabled.
-
-➡️ **[Read full Implementation Strategy](./03-implementation-strategy.md)**
-
----
-
-## 4. Code Samples
-
-C++ implementation examples are provided for the core telemetry infrastructure and key modules:
-
-- `Telemetry.h` - Core interface for tracer access and span creation
-- `SpanGuard.h` - RAII wrapper for automatic span lifecycle management
-- `TracingInstrumentation.h` - Macros for conditional instrumentation
-- Protocol Buffer extensions for trace context propagation
-- Module-specific instrumentation (RPC, Consensus, P2P, JobQueue)
-- Remaining modules (PathFinding, TxQ, Validator, etc.) follow the same patterns

-

-
-## 5. Configuration Reference
-
-> **OTLP** = OpenTelemetry Protocol | **APM** = Application Performance Monitoring
-
-Configuration is handled through the `[telemetry]` section in `xrpld.cfg` with options for enabling/disabling, exporter selection, endpoint configuration, sampling ratios, and component-level filtering. CMake integration includes a `XRPL_ENABLE_TELEMETRY` option for compile-time control.
-
-OpenTelemetry Collector configurations are provided for development and production (with tail-based sampling, Tempo, and Elastic APM). Docker Compose examples enable quick local development environment setup.

-The implementation spans 9 weeks across 5 phases:
-
-| Phase | Duration  | Focus               | Key Deliverables                                    |

-## 7. Observability Backends
-
-> **APM** = Application Performance Monitoring | **GCS** = Google Cloud Storage
-
-Grafana Tempo is recommended for all environments due to its cost-effectiveness and Grafana integration, while Elastic APM is ideal for organizations with existing Elastic infrastructure.
-
-The recommended production architecture uses a gateway collector pattern with regional collectors performing tail-based sampling, routing traces to multiple backends (Tempo for primary storage, Elastic for log correlation, S3/GCS for long-term archive).

-> **Goal**: Build a minimal end-to-end proof of concept that demonstrates distributed tracing in xrpld. A successful POC will show RPC request traces flowing from xrpld through an OTel Collector into Tempo, viewable in Grafana.
->
-> **Scope**: RPC tracing only (highest value, lowest risk per the [CRAWL phase](./06-implementation-phases.md#6102-quick-wins-immediate-value) in the implementation phases). No cross-node P2P context propagation or consensus tracing in the POC.

-## Task 0: Docker Observability Stack Setup
-
-> **OTLP** = OpenTelemetry Protocol
-
-**Objective**: Stand up the backend infrastructure to receive, store, and display traces.
-
-**What to do**:
-
-- Create `docker/telemetry/docker-compose.yml` in the repo with three services:
-  1. **OpenTelemetry Collector** (`otel/opentelemetry-collector-contrib:0.92.0`)
-     - Expose ports `4317` (OTLP gRPC) and `4318` (OTLP HTTP)
-     - Expose port `13133` (health check)
-     - Mount a config file `docker/telemetry/otel-collector-config.yaml`
-  2. **Tempo** (`grafana/tempo:2.6.1`)
-     - Expose port `3200` (HTTP API) and `4317` (OTLP gRPC, internal)
-  3. **Grafana** (`grafana/grafana:latest`) — optional but useful
-     - Expose port `3000`
-     - Enable anonymous admin access for local dev (`GF_AUTH_ANONYMOUS_ENABLED=true`, `GF_AUTH_ANONYMOUS_ORG_ROLE=Admin`)
-     - Provision Tempo as a data source via `docker/telemetry/grafana/provisioning/datasources/tempo.yaml`
-
-- Create `docker/telemetry/otel-collector-config.yaml`:
-
-  ```yaml
-  receivers:
-    otlp:
-      protocols:
-        grpc:
-          endpoint: 0.0.0.0:4317
-        http:
-          endpoint: 0.0.0.0:4318
-
-  processors:
-    batch:
-      timeout: 1s
-      send_batch_size: 100
-
-  exporters:
-    logging:
-      verbosity: detailed
-    otlp/tempo:
-      endpoint: tempo:4317
-      tls:
-        insecure: true
-
-  service:
-    pipelines:
-      traces:
-        receivers: [otlp]
-        processors: [batch]
-        exporters: [logging, otlp/tempo]
-  ```
-
-- Create Grafana Tempo datasource provisioning file at `docker/telemetry/grafana/provisioning/datasources/tempo.yaml`:
-  ```yaml
-  apiVersion: 1
-  datasources:
-    - name: Tempo
-      type: tempo
-      access: proxy
-      url: http://tempo:3200
-  ```
-
-**Verification**: Run `docker compose -f docker/telemetry/docker-compose.yml up -d`, then:
-
-- `curl http://localhost:13133` returns healthy (Collector)
-- `http://localhost:3000` opens Grafana (Tempo datasource available, no traces yet)

-## Task 1: Add OpenTelemetry C++ SDK Dependency
-
-**Objective**: Make `opentelemetry-cpp` available to the build system.
-
-**What to do**:
-
-- Edit `conanfile.py` to add `opentelemetry-cpp` as an **optional** dependency. The gRPC otel plugin flag (`"grpc/*:otel_plugin": False`) in the existing conanfile may need to remain false — we pull the OTel SDK separately.
-  - Add a Conan option: `with_telemetry = [True, False]` defaulting to `False`
-  - When `with_telemetry` is `True`, add `opentelemetry-cpp` to `self.requires()`
-  - Required OTel Conan components: `opentelemetry-cpp` (which bundles api, sdk, and exporters). If the package isn't in Conan Center, consider using `FetchContent` in CMake or building from source as a fallback.
-- Edit `CMakeLists.txt`:
-  - Add option: `option(XRPL_ENABLE_TELEMETRY "Enable OpenTelemetry tracing" OFF)`
-  - When ON, `find_package(opentelemetry-cpp CONFIG REQUIRED)` and add compile definition `XRPL_ENABLE_TELEMETRY`
-  - When OFF, do nothing (zero build impact)
-- Verify the build succeeds with `-DXRPL_ENABLE_TELEMETRY=OFF` (no regressions) and with `-DXRPL_ENABLE_TELEMETRY=ON` (SDK links successfully).

-## Task 2: Create Core Telemetry Interface and NullTelemetry
-
-**Objective**: Define the `Telemetry` abstract interface and a no-op implementation so the rest of the codebase can reference telemetry without hard-depending on the OTel SDK.
-
-**What to do**:
-
-- Create `include/xrpl/telemetry/Telemetry.h`:
-  - Define `namespace xrpl::telemetry`
-  - Define `struct Telemetry::Setup` holding: `enabled`, `exporterEndpoint`, `samplingRatio`, `serviceName`, `serviceVersion`, `serviceInstanceId`, `traceRpc`, `traceTransactions`, `traceConsensus`, `tracePeer`
-  - Define abstract `class Telemetry` with:
-    - `virtual void start() = 0;`
-    - `virtual void stop() = 0;`
-    - `virtual bool isEnabled() const = 0;`
-    - `virtual nostd::shared_ptr<Tracer> getTracer(string_view name = "xrpld") = 0;`
-    - `virtual nostd::shared_ptr<Span> startSpan(string_view name, SpanKind kind = kInternal) = 0;`
-    - `virtual nostd::shared_ptr<Span> startSpan(string_view name, Context const& parentContext, SpanKind kind = kInternal) = 0;`
-    - `virtual bool shouldTraceRpc() const = 0;`
-    - `virtual bool shouldTraceTransactions() const = 0;`
-    - `virtual bool shouldTraceConsensus() const = 0;`
-  - Factory: `std::unique_ptr<Telemetry> make_Telemetry(Setup const&, beast::Journal);`
-  - Config parser: `Telemetry::Setup setup_Telemetry(Section const&, std::string const& nodePublicKey, std::string const& version);`
-
-- Create `include/xrpl/telemetry/SpanGuard.h`:
-  - RAII guard that takes an `nostd::shared_ptr<Span>`, creates a `Scope`, and calls `span->End()` in destructor.
-  - Convenience: `setAttribute()`, `setOk()`, `setStatus()`, `addEvent()`, `recordException()`, `context()`
-  - See [04-code-samples.md](./04-code-samples.md) §4.2 for the full implementation.
-
-- Create `src/libxrpl/telemetry/NullTelemetry.cpp`:
-  - Implements `Telemetry` with all no-ops.
-  - `isEnabled()` returns `false`, `startSpan()` returns a noop span.
-  - This is used when `XRPL_ENABLE_TELEMETRY` is OFF or `enabled=0` in config.
-
-- Guard all OTel SDK headers behind `#ifdef XRPL_ENABLE_TELEMETRY`. The `NullTelemetry` implementation should compile without the OTel SDK present.

-## Task 3: Implement OTel-Backed Telemetry
-
-> **OTLP** = OpenTelemetry Protocol
-
-**Objective**: Implement the real `Telemetry` class that initializes the OTel SDK, configures the OTLP exporter and batch processor, and creates tracers/spans.
-
-**What to do**:
-
-- Create `src/libxrpl/telemetry/Telemetry.cpp` (compiled only when `XRPL_ENABLE_TELEMETRY=ON`):
-  - `class TelemetryImpl : public Telemetry` that:
-    - In `start()`: creates a `TracerProvider` with:
-      - Resource attributes: `service.name`, `service.version`, `service.instance.id`
-      - An `OtlpHttpExporter` pointed at `setup.exporterEndpoint` (default `localhost:4318`)
-      - A `BatchSpanProcessor` with configurable batch size and delay
-      - A `TraceIdRatioBasedSampler` using `setup.samplingRatio`
-    - Sets the global `TracerProvider`
-    - In `stop()`: calls `ForceFlush()` then shuts down the provider
-    - In `startSpan()`: delegates to `getTracer()->StartSpan(name, ...)`
-    - `shouldTraceRpc()` etc. read from `Setup` fields
-
-- Create `src/libxrpl/telemetry/TelemetryConfig.cpp`:
-  - `setup_Telemetry()` parses the `[telemetry]` config section from `xrpld.cfg`
-  - Maps config keys: `enabled`, `exporter`, `endpoint`, `sampling_ratio`, `trace_rpc`, `trace_transactions`, `trace_consensus`, `trace_peer`
-
-- Wire `make_Telemetry()` factory:
-  - If `setup.enabled` is true AND `XRPL_ENABLE_TELEMETRY` is defined: return `TelemetryImpl`
-  - Otherwise: return `NullTelemetry`
-
-- Add telemetry source files to CMake. When `XRPL_ENABLE_TELEMETRY=ON`, compile `Telemetry.cpp` and `TelemetryConfig.cpp` and link against `opentelemetry-cpp::api`, `opentelemetry-cpp::sdk`, `opentelemetry-cpp::otlp_grpc_exporter`. When OFF, compile only `NullTelemetry.cpp`.
-
-**Key new files**:
-
-- `src/libxrpl/telemetry/Telemetry.cpp`
-- `src/libxrpl/telemetry/TelemetryConfig.cpp`
-
-**Key modified files**:
-
-- `CMakeLists.txt` (add telemetry library target)

-
-## Task 4: Integrate Telemetry into Application Lifecycle
-
-**Objective**: Wire the `Telemetry` object into the `ServiceRegistry` / `Application` so all components can access it.
-
-**What to do**:
-
-- Edit `include/xrpl/core/ServiceRegistry.h`:
-  - Forward-declare `namespace telemetry { class Telemetry; }` inside `namespace xrpl`
-  - Add pure virtual method: `virtual telemetry::Telemetry& getTelemetry() = 0;`
-  - (`Application` extends `ServiceRegistry`, so this is automatically available on `Application` too)
-
-- Edit `src/xrpld/app/main/Application.cpp` (the `ApplicationImp` class):
-  - Add member: `std::unique_ptr<telemetry::Telemetry> telemetry_;`
-  - In the member initializer list, construct telemetry with an empty
-    `serviceInstanceId` (node identity is not yet known):
-    ```cpp
-    , telemetry_(
-          telemetry::make_Telemetry(
-              telemetry::setup_Telemetry(
-                  config_->section("telemetry"),
-                  "",  // Updated later via setServiceInstanceId()
-                  BuildInfo::getVersionString()),
-              logs_->journal("Telemetry")))
-    ```
-  - In `setup()`, after `nodeIdentity_` is resolved, inject the node
-    public key as the service instance ID:
-    ```cpp
-    if (!config_->section("telemetry").exists("service_instance_id"))
-        telemetry_->setServiceInstanceId(
-            toBase58(TokenType::NodePublic, nodeIdentity_->first));
-    ```
-  - In `start()`: call `telemetry_->start()`
-  - In `run()` (shutdown path): call `telemetry_->stop()` (to flush pending spans)
-  - Implement `getTelemetry()` override: return `*telemetry_`
-
-- Add `[telemetry]` section to the example config `cfg/xrpld-example.cfg`:
-  ```ini
-  # [telemetry]
-  # enabled=1
-  # endpoint=http://localhost:4318/v1/traces
-  # sampling_ratio=1.0
-  # trace_rpc=1
-  ```
-
-> **Access patterns**: Components holding `ServiceRegistry&` (e.g.
-> `NetworkOPsImp`) call `registry_.get().getTelemetry()`. Components
-> holding `Application&` (e.g. `ServerHandler`, `PeerImp`,
-> `RCLConsensusAdaptor`) call `app_.getTelemetry()` directly. Both
-> resolve to the same `Telemetry` instance.
-
-**Key modified files**:
-
-- `include/xrpl/core/ServiceRegistry.h`
-- `src/xrpld/app/main/Application.cpp`
-- `cfg/xrpld-example.cfg` (example config)
-
-**Reference**:

-- [03-implementation-strategy.md §3.9.2](./03-implementation-strategy.md) — File impact assessment: `Application.cpp` ~15 lines added, ~3 changed (Low risk)

-
-## Task 5: Create Instrumentation Macros
-
-**Objective**: Define convenience macros that make instrumenting code one-liners, and that compile to zero-cost no-ops when telemetry is disabled.
-
-**What to do**:
-
-- Create `src/xrpld/telemetry/TracingInstrumentation.h`:
-  - When `XRPL_ENABLE_TELEMETRY` is defined:
-
-    ```cpp
-    #define XRPL_TRACE_SPAN(telemetry, name) \
-        auto _xrpl_span_ = (telemetry).startSpan(name); \
-        ::xrpl::telemetry::SpanGuard _xrpl_guard_(_xrpl_span_)
-
-    #define XRPL_TRACE_RPC(telemetry, name) \
-        std::optional<::xrpl::telemetry::SpanGuard> _xrpl_guard_; \
-        if ((telemetry).shouldTraceRpc()) { \
-            _xrpl_guard_.emplace((telemetry).startSpan(name)); \
-        }
-
-    #define XRPL_TRACE_SET_ATTR(key, value) \
-        if (_xrpl_guard_.has_value()) { \
-            _xrpl_guard_->setAttribute(key, value); \
-        }
-
-    #define XRPL_TRACE_EXCEPTION(e) \
-        if (_xrpl_guard_.has_value()) { \
-            _xrpl_guard_->recordException(e); \
-        }
-    ```
-
-  - When `XRPL_ENABLE_TELEMETRY` is NOT defined, all macros expand to `((void)0)`

-
-## Task 6: Instrument RPC ServerHandler
-
-> **WS** = WebSocket
-
-**Objective**: Add tracing to the HTTP RPC entry point so every incoming RPC request creates a span.
-
-**What to do**:
-
-- Edit `src/xrpld/rpc/detail/ServerHandler.cpp`:
-  - `#include` the `TracingInstrumentation.h` header
-  - In `ServerHandler::onRequest(Session& session)`:
-    - At the top of the method, add: `XRPL_TRACE_RPC(app_.getTelemetry(), "rpc.request");`
-    - After the RPC command name is extracted, set attribute: `XRPL_TRACE_SET_ATTR("xrpl.rpc.command", command);`
-    - After the response status is known, set: `XRPL_TRACE_SET_ATTR("http.status_code", static_cast<int64_t>(statusCode));`
-    - Wrap error paths with: `XRPL_TRACE_EXCEPTION(e);`
-  - In `ServerHandler::processRequest(...)`:
-    - Add a child span: `XRPL_TRACE_RPC(app_.getTelemetry(), "rpc.process");`
-    - Set method attribute: `XRPL_TRACE_SET_ATTR("xrpl.rpc.method", request_method);`
-  - In `ServerHandler::onWSMessage(...)` (WebSocket path):
-    - Add: `XRPL_TRACE_RPC(app_.getTelemetry(), "rpc.ws.message");`
-
-- The goal is to see spans like:
-  ```
-  rpc.request
-    └── rpc.process
-  ```
-  in Tempo/Grafana for every HTTP RPC call.

----
-
-## Task 7: Instrument RPC Command Execution
-
-**Objective**: Add per-command tracing inside the RPC handler so each command (e.g., `submit`, `account_info`, `server_info`) gets its own child span.
-
-**What to do**:
-
-- Edit `src/xrpld/rpc/detail/RPCHandler.cpp`:
-  - `#include` the `TracingInstrumentation.h` header
-  - In `doCommand(RPC::JsonContext& context, Json::Value& result)`:
-    - At the top: `XRPL_TRACE_RPC(context.app.getTelemetry(), "rpc.command." + context.method);`
-    - Set attributes:
-      - `XRPL_TRACE_SET_ATTR("xrpl.rpc.command", context.method);`
-      - `XRPL_TRACE_SET_ATTR("xrpl.rpc.version", static_cast<int64_t>(context.apiVersion));`
-      - `XRPL_TRACE_SET_ATTR("xrpl.rpc.role", (context.role == Role::ADMIN) ? "admin" : "user");`
-    - On success: `XRPL_TRACE_SET_ATTR("xrpl.rpc.status", "success");`
-    - On error: `XRPL_TRACE_SET_ATTR("xrpl.rpc.status", "error");` and set the error message
-
-- After this, traces in Tempo/Grafana should look like:
-  ```
-  rpc.request  (xrpl.rpc.command=account_info)
-    └── rpc.process
-          └── rpc.command.account_info  (xrpl.rpc.version=2, xrpl.rpc.role=user, xrpl.rpc.status=success)

-## Task 8: Build, Run, and Verify End-to-End
-
-> **OTLP** = OpenTelemetry Protocol
-
-**Objective**: Prove the full pipeline works: xrpld emits traces -> OTel Collector receives them -> Tempo stores them for Grafana visualization.
-
-**What to do**:
-
-1. **Start the Docker stack**:
-
-   ```bash
-   docker compose -f docker/telemetry/docker-compose.yml up -d
-   ```
-
-   Verify Collector health: `curl http://localhost:13133`
-
-2. **Build xrpld with telemetry**:
-
-   ```bash
-   # Adjust for your actual build workflow
-   conan install . --build=missing -o with_telemetry=True
-   cmake --preset default -DXRPL_ENABLE_TELEMETRY=ON
-   cmake --build --preset default
-   ```
-
-3. **Configure xrpld**:
-   Add to `xrpld.cfg` (or your local test config):
-
-   ```ini
-   [telemetry]
-   enabled=1
-   endpoint=localhost:4317
-   sampling_ratio=1.0
-   trace_rpc=1
-   ```
-
-4. **Start xrpld** in standalone mode:
-
-   ```bash
-   ./rippled --conf xrpld.cfg -a --start
-   ```
-
-5. **Generate RPC traffic**:
-
-   ```bash
-   # server_info
-   curl -s -X POST http://localhost:5005 \
-     -H "Content-Type: application/json" \
-     -d '{"method":"server_info","params":[{}]}'
-
-   # ledger
-   curl -s -X POST http://localhost:5005 \
-     -H "Content-Type: application/json" \
-     -d '{"method":"ledger","params":[{"ledger_index":"current"}]}'
-
-   # account_info (will error in standalone, that's fine — we trace errors too)
-   curl -s -X POST http://localhost:5005 \
-     -H "Content-Type: application/json" \
-     -d '{"method":"account_info","params":[{"account":"rHb9CJAWyB4rj91VRWn96DkukG4bwdtyTh"}]}'
-   ```
-
-6. **Verify in Grafana (Tempo)**:
-   - Open `http://localhost:3000`
-   - Navigate to Explore → select Tempo datasource
-   - Search for service `xrpld`
-   - Confirm you see traces with spans: `rpc.request` -> `rpc.process` -> `rpc.command.server_info`
-   - Click into a trace and verify attributes: `xrpl.rpc.command`, `xrpl.rpc.status`, `xrpl.rpc.version`
-
-7. **Verify zero-overhead when disabled**:
-   - Rebuild with `XRPL_ENABLE_TELEMETRY=OFF`, or set `enabled=0` in config
-   - Run the same RPC calls
-   - Confirm no new traces appear and no errors in xrpld logs
-
-**Verification Checklist**:
-
-- [ ] Docker stack starts without errors
-- [ ] xrpld builds with `-DXRPL_ENABLE_TELEMETRY=ON`
-- [ ] xrpld starts and connects to OTel Collector (check xrpld logs for telemetry messages)
-- [ ] Traces appear in Grafana/Tempo under service "xrpld"
-- [ ] Span hierarchy is correct (parent-child relationships)
-- [ ] Span attributes are populated (`xrpl.rpc.command`, `xrpl.rpc.status`, etc.)
-- [ ] Error spans show error status and message
-- [ ] Building with `XRPL_ENABLE_TELEMETRY=OFF` produces no regressions
-- [ ] Setting `enabled=0` at runtime produces no traces and no errors

-## Task 9: Document POC Results and Next Steps
-
-> **OTLP** = OpenTelemetry Protocol | **WS** = WebSocket
-
-**Objective**: Capture findings, screenshots, and remaining work for the team.
-
-**What to do**:
-
-- Take screenshots of Grafana/Tempo showing:
-  - The service list with "xrpld"
-  - A trace with the full span tree
-  - Span detail view showing attributes
-- Document any issues encountered (build issues, SDK quirks, missing attributes)
-- Note performance observations (build time impact, any noticeable runtime overhead)
-- Write a short summary of what the POC proves and what it doesn't cover yet:
-  - **Proves**: OTel SDK integrates with xrpld, OTLP export works, RPC traces visible
-  - **Doesn't cover**: Cross-node P2P context propagation, consensus tracing, protobuf trace context, W3C traceparent header extraction, tail-based sampling, production deployment
-- Outline next steps (mapping to the full plan phases):
-  - [Phase 2](./06-implementation-phases.md) completion: [W3C header extraction](./02-design-decisions.md) (§2.5), WebSocket tracing, all [RPC handlers](./01-architecture-analysis.md) (§1.6)
-  - [Phase 3](./06-implementation-phases.md): [Protobuf `TraceContext` message](./04-code-samples.md) (§4.4), [transaction relay tracing](./04-code-samples.md) (§4.5.1) across nodes
-  - [Phase 4](./06-implementation-phases.md): [Consensus round and phase tracing](./04-code-samples.md) (§4.5.2)
-  - [Phase 5](./06-implementation-phases.md): [Production collector config](./05-configuration-reference.md) (§5.5.2), [Grafana dashboards](./07-observability-backends.md) (§7.6), [alerting](./07-observability-backends.md) (§7.6.3)

-## Next Steps (Post-POC)
-
-> **OTLP** = OpenTelemetry Protocol | **WS** = WebSocket
-
-### Metrics Pipeline for Grafana Dashboards
-
-The current POC exports **traces only**. Grafana's Explore view can query Tempo for individual traces, but time-series charts (latency histograms, request throughput, error rates) require a **metrics pipeline**. To enable this:
-
-1. **Add a `spanmetrics` connector** to the OTel Collector config that derives RED metrics (Rate, Errors, Duration) from trace spans automatically:
-
-   ```yaml
-   connectors:
-     spanmetrics:
-       histogram:
-         explicit:
-           buckets: [1ms, 5ms, 10ms, 25ms, 50ms, 100ms, 250ms, 500ms, 1s, 5s]
-       dimensions:
-         - name: xrpl.rpc.command
-         - name: xrpl.rpc.status
-
-   exporters:
-     prometheus:
-       endpoint: 0.0.0.0:8889
-
-   service:
-     pipelines:
-       traces:
-         receivers: [otlp]
-         processors: [batch]
-         exporters: [debug, otlp/tempo, spanmetrics]
-       metrics:
-         receivers: [spanmetrics]
-         exporters: [prometheus]
-   ```
-
-2. **Add Prometheus** to the Docker Compose stack to scrape the collector's metrics endpoint.
-
-3. **Add Prometheus as a Grafana datasource** and build dashboards for:
-   - RPC request latency (p50/p95/p99) by command
-   - RPC throughput (requests/sec) by command
-   - Error rate by command
-   - Span duration distribution
-
-### Additional Instrumentation
-
-- **W3C `traceparent` header extraction** in `ServerHandler` to support cross-service context propagation from external callers
-- **WebSocket RPC tracing** in `ServerHandler::onWSMessage()`
-- **Transaction relay tracing** across nodes using protobuf `TraceContext` messages
-- **Consensus round and phase tracing** for validator coordination visibility
-- **Ledger close tracing** to measure close-to-validated latency
-
-### Production Hardening
-
-- **Tail-based sampling** in the OTel Collector to reduce volume while retaining error/slow traces
-- **TLS configuration** for the OTLP exporter in production deployments
-- **Resource limits** on the batch processor queue to prevent unbounded memory growth
-- **Health monitoring** for the telemetry pipeline itself (collector lag, export failures)

-# OpenTelemetry Distributed Tracing for xrpld
-
----
-
-## Slide 1: Introduction
-
-> **CNCF** = Cloud Native Computing Foundation
-
-### What is OpenTelemetry?
-
-OpenTelemetry is an open-source, CNCF-backed observability framework for distributed tracing, metrics, and logs.
-
-### Why OpenTelemetry for xrpld?
-
-- **End-to-End Transaction Visibility**: Track transactions from submission → consensus → ledger inclusion
-- **Cross-Node Correlation**: Follow requests across multiple independent nodes using a unique `trace_id`
-- **Consensus Round Analysis**: Understand timing and behavior across validators
-- **Incident Debugging**: Correlate events across distributed nodes during issues
-
-```mermaid
-flowchart LR
-    A["Node A<br/>tx.receive<br/>trace_id: abc123"] --> B["Node B<br/>tx.relay<br/>trace_id: abc123"] --> C["Node C<br/>tx.validate<br/>trace_id: abc123"] --> D["Node D<br/>ledger.apply<br/>trace_id: abc123"]
-
-    style A fill:#1565c0,stroke:#0d47a1,color:#fff
-    style B fill:#2e7d32,stroke:#1b5e20,color:#fff
-    style C fill:#2e7d32,stroke:#1b5e20,color:#fff
-    style D fill:#e65100,stroke:#bf360c,color:#fff
-```
-
-**Reading the diagram:**
-
-- **Node A (blue, leftmost)**: The originating node that first receives the transaction and assigns a new `trace_id: abc123`; this ID becomes the correlation key for the entire distributed trace.
-- **Node B and Node C (green, middle)**: Relay and validation nodes — each creates its own span but carries the same `trace_id`, so their work is linked to the original submission without any central coordinator.
-- **Node D (orange, rightmost)**: The final node that applies the transaction to the ledger; the trace now spans the full lifecycle from submission to ledger inclusion.
-- **Left-to-right flow**: The horizontal progression shows the real-world message path — a transaction hops from node to node, and the shared `trace_id` stitches all hops into a single queryable trace.
-
-> **Trace ID: abc123** — All nodes share the same trace, enabling cross-node correlation.

-| Feature             | OpenTelemetry    | Jaeger           | Zipkin             | SkyWalking | Pinpoint   | Prometheus |
-| ------------------- | ---------------- | ---------------- | ------------------ | ---------- | ---------- | ---------- |
-| **Tracing**         | YES              | YES              | YES                | YES        | YES        | NO         |
-| **Metrics**         | YES              | NO               | NO                 | YES        | YES        | YES        |
-| **Logs**            | YES              | NO               | NO                 | YES        | NO         | NO         |
-| **C++ SDK**         | YES Official     | YES (Deprecated) | YES (Unmaintained) | NO         | NO         | YES        |
-| **Vendor Neutral**  | YES Primary goal | NO               | NO                 | NO         | NO         | NO         |
-| **Instrumentation** | Manual + Auto    | Manual           | Manual             | Auto-first | Auto-first | Manual     |
-| **Backend**         | Any (exporters)  | Self             | Self               | Self       | Self       | Self       |
-| **CNCF Status**     | Incubating       | Graduated        | NO                 | Incubating | NO         | Graduated  |
-
-> **Why OpenTelemetry?** It's the only actively maintained, full-featured C++ option with vendor neutrality — allowing export to Tempo, Prometheus, Grafana, or any commercial backend without changing instrumentation.
-
----
-
-## Slide 3: Adoption Scope — Traces Only (Current Plan)
-
-OpenTelemetry supports three signal types: **Traces**, **Metrics**, and **Logs**. xrpld already captures metrics (StatsD via Beast Insight) and logs (Journal/PerfLog). The question is: how much of OTel do we adopt?
-
-> **Scenario A**: Add distributed tracing. Keep StatsD for metrics and Journal for logs.
-
-```mermaid
-flowchart LR
-    subgraph xrpld["xrpld Process"]
-        direction TB
-        OTel["OTel SDK<br/>(Traces)"]
-        Insight["Beast Insight<br/>(StatsD Metrics)"]
-        Journal["Journal + PerfLog<br/>(Logging)"]
-    end
-
-    OTel -->|"OTLP"| Collector["OTel Collector"]
-    Insight -->|"UDP"| StatsD["StatsD Server"]
-    Journal -->|"File I/O"| LogFile["perf.log / debug.log"]
-
-    Collector --> Tempo["Tempo"]
-    StatsD --> Graphite["Graphite / Grafana"]
-    LogFile --> Loki["Loki (optional)"]

-    style Journal fill:#e65100,stroke:#bf360c,color:#fff
-    style Collector fill:#2e7d32,stroke:#1b5e20,color:#fff
-```
-
-| Aspect                         | Details                                                                                                         |
-| ------------------------------ | --------------------------------------------------------------------------------------------------------------- |
-| **What changes for operators** | Deploy OTel Collector + trace backend. Existing StatsD and log pipelines stay as-is.                            |
-| **Codebase impact**            | New `Telemetry` module (~1500 LOC). Beast Insight and Journal untouched.                                        |
-| **New capabilities**           | Cross-node trace correlation, span-based debugging, request lifecycle visibility.                               |
-| **What we still can't do**     | Correlate metrics with specific traces natively. StatsD metrics remain fire-and-forget with no trace exemplars. |
-| **Maintenance burden**         | Three separate observability systems to maintain (OTel + StatsD + Journal).                                     |
-| **Risk**                       | Lowest — additive change, no existing systems disturbed.                                                        |
-

-
-## Slide 4: Future Adoption — Metrics & Logs via OTel
-
-### Scenario B: + OTel Metrics (Replace StatsD)
-
-> Migrate StatsD to OTel Metrics API, exposing Prometheus-compatible metrics. Remove Beast Insight.
-
-```mermaid
-flowchart LR
-    subgraph xrpld["xrpld Process"]
-        direction TB
-        OTel["OTel SDK<br/>(Traces + Metrics)"]
-        Journal["Journal + PerfLog<br/>(Logging)"]
-    end
-
-    OTel -->|"OTLP"| Collector["OTel Collector"]
-    Journal -->|"File I/O"| LogFile["perf.log / debug.log"]
-
-    Collector --> Tempo["Tempo<br/>(Traces)"]
-    Collector --> Prom["Prometheus<br/>(Metrics)"]
-    LogFile --> Loki["Loki (optional)"]
-
-    style xrpld fill:#424242,stroke:#212121,color:#fff
-    style OTel fill:#2e7d32,stroke:#1b5e20,color:#fff
-    style Journal fill:#e65100,stroke:#bf360c,color:#fff
-    style Collector fill:#2e7d32,stroke:#1b5e20,color:#fff
-```
-
-- **Better metrics?** Yes — Prometheus gives native histograms (p50/p95/p99), multi-dimensional labels, and exemplars linking metric spikes to traces.
-- **Codebase**: Remove `Beast::Insight` + `StatsDCollector` (~2000 LOC). Single SDK for traces and metrics.
-- **Operator effort**: Rewrite dashboards from StatsD/Graphite queries to PromQL. Run both in parallel during transition.
-- **Risk**: Medium — operators must migrate monitoring infrastructure.
-
-### Scenario C: + OTel Logs (Full Stack)
-
-> Also replace Journal logging with OTel Logs API. Single SDK for everything.
-
-```mermaid
-flowchart LR
-    subgraph xrpld["xrpld Process"]
-        OTel["OTel SDK<br/>(Traces + Metrics + Logs)"]
-    end
-
-    OTel -->|"OTLP"| Collector["OTel Collector"]
-
-    Collector --> Tempo["Tempo<br/>(Traces)"]
-    Collector --> Prom["Prometheus<br/>(Metrics)"]
-    Collector --> Loki["Loki / Elastic<br/>(Logs)"]
-
-    style xrpld fill:#424242,stroke:#212121,color:#fff
-    style OTel fill:#2e7d32,stroke:#1b5e20,color:#fff
-    style Collector fill:#2e7d32,stroke:#1b5e20,color:#fff
-```
-
-- **Structured logging**: OTel Logs API outputs structured records with `trace_id`, `span_id`, severity, and attributes by design.
-- **Full correlation**: Every log line carries `trace_id`. Click trace → see logs. Click metric spike → see trace → see logs.
-- **Codebase**: Remove Beast Insight (~2000 LOC) + simplify Journal/PerfLog (~3000 LOC). One dependency instead of three.
-- **Risk**: Highest — `beast::Journal` is deeply embedded in every component. Large refactor. OTel C++ Logs API is newer (stable since v1.11, less battle-tested).
-
-### Recommendation

-    A["Phase 1<br/><b>Traces Only</b><br/>(Current Plan)"] --> B["Phase 2<br/><b>+ Metrics</b><br/>(Replace StatsD)"] --> C["Phase 3<br/><b>+ Logs</b><br/>(Full OTel)"]

-    style B fill:#1565c0,stroke:#0d47a1,color:#fff
-    style C fill:#e65100,stroke:#bf360c,color:#fff
-```
-
-| Phase                | Signal    | Strategy                                                       | Risk   |
-| -------------------- | --------- | -------------------------------------------------------------- | ------ |
-| **Phase 1** (now)    | Traces    | Add OTel traces. Keep StatsD and Journal. Prove value.         | Low    |
-| **Phase 2** (future) | + Metrics | Migrate StatsD → Prometheus via OTel. Remove Beast Insight.    | Medium |
-| **Phase 3** (future) | + Logs    | Adopt OTel Logs API. Align with structured logging initiative. | High   |
-
-> **Key Takeaway**: Start with traces (unique value, lowest risk), then incrementally adopt metrics and logs as the OTel infrastructure proves itself.

-| **Data**              | JSON log entries      | Counters, gauges      | Spans with context          |
-| **Correlation**       | By timestamp          | By metric name        | By `trace_id`               |
-| **Overhead**          | Low (file I/O)        | Low (UDP)             | Low-Medium (configurable)   |
-| **Question Answered** | "What happened here?" | "How many? How fast?" | **"What was the journey?"** |
-
-### Use Case Matrix
-
-| Scenario                         | PerfLog | StatsD | OpenTelemetry |
-| -------------------------------- | ------- | ------ | ------------- |
-| "How many TXs per second?"       | ❌      | ✅     | ❌            |
-| "Why was this specific TX slow?" | ⚠️      | ❌     | ✅            |
-| "Which node delayed consensus?"  | ❌      | ❌     | ✅            |
-| "Show TX journey across 5 nodes" | ❌      | ❌     | ✅            |
-
-> **Key Insight**: In the **traces-only** approach (Phase 1), OpenTelemetry **complements** existing systems. In future phases, OTel metrics and logs could **replace** StatsD and Journal respectively — see Slides 3-4 for the full adoption roadmap.

-    style Collector fill:#e65100,stroke:#bf360c,color:#fff
-```
-
-**Reading the diagram:**
-
-- **Core Services (blue, top)**: RPC Server, Overlay, and Consensus are the three primary components that generate trace data — they represent the entry points for client requests, peer messages, and consensus rounds respectively.
-- **Telemetry Module (green, middle)**: The OpenTelemetry SDK sits below the core services and receives span data from all three; it acts as a single collection point within the xrpld process.
-- **OTel Collector (orange, center)**: An external process that receives spans over OTLP/gRPC from the Telemetry Module; it decouples xrpld from backend choices and handles batching, sampling, and routing.
-- **Backends (bottom row)**: Tempo and Elastic APM are interchangeable — the Collector fans out to any combination, so operators can switch backends without modifying xrpld code.
-- **Top-to-bottom flow**: Data flows from instrumented code down through the SDK, out over the network to the Collector, and finally into storage/visualization backends.
-
-### Context Propagation
-
-```mermaid

-    participant Client
-    participant NodeA as Node A
-    participant NodeB as Node B
-
-    Client->>NodeA: Submit TX (no context)
-    Note over NodeA: Creates trace_id: abc123<br/>span: tx.receive
-    NodeA->>NodeB: Relay TX<br/>(traceparent: abc123)
-    Note over NodeB: Links to trace_id: abc123<br/>span: tx.relay
-```
-
-- **HTTP/RPC**: W3C Trace Context headers (`traceparent`)
-- **P2P Messages**: Protocol Buffer extension fields

-| Phase | Focus               | Key Deliverables                             | Effort  |
-| ----- | ------------------- | -------------------------------------------- | ------- |
-| 1     | Core Infrastructure | SDK integration, Telemetry interface, Config | 10 days |
-| 2     | RPC Tracing         | HTTP context extraction, Handler spans       | 10 days |
-| 3     | Transaction Tracing | Protobuf context, P2P relay propagation      | 10 days |
-| 4     | Consensus Tracing   | Round spans, Proposal/validation tracing     | 10 days |
-| 5     | Documentation       | Runbook, Dashboards, Training                | 7 days  |
-
-**Total Effort**: ~47 developer-days (2 developers)
-
-> **Future Phases** (not in current scope): After traces are stable, OTel metrics can replace StatsD (~3 weeks), and OTel logs can replace Journal (~4 weeks, aligned with structured logging initiative). See Slides 3-4 for the full adoption roadmap.

-| Metric            | Overhead   | Notes                                            |
-| ----------------- | ---------- | ------------------------------------------------ |
-| **CPU**           | 1-3%       | Span creation and attribute setting              |
-| **Memory**        | ~10 MB     | SDK statics + batch buffer + worker thread stack |
-| **Network**       | 10-50 KB/s | Compressed OTLP export to collector              |
-| **Latency (p99)** | <2%        | With proper sampling configuration               |
-
-#### How We Arrived at These Numbers

-**Assumptions (XRPL mainnet baseline)**:
-
-| Parameter                 | Value                  | Source                                                                                              |
-| ------------------------- | ---------------------- | --------------------------------------------------------------------------------------------------- |

-
-> **CPU overhead**: 4.0 μs / 200 μs baseline = **~2.0% per transaction**. Under high load with consensus + RPC spans overlapping, reaches ~3%. Consensus itself adds only ~36 μs per 3-second round (~0.001%), so the TX path dominates. On production server hardware (3+ GHz Xeon), span creation drops to ~500-600 ns, bringing per-TX cost to ~2.6 μs (~1.3%).

-| --------------------------------------------- | ------------------ | ------------------------------------- |

-
-> Memory plateaus once the export queue fills — the `max_queue_size=2048` config bounds growth.
-> The worker thread stack (~8 MB) dominates the static footprint but is virtual memory; actual RSS
-> depends on stack usage (typically much less). Active spans are larger than originally estimated
-> (~500-800 bytes) because the OTel SDK `Span` object includes a mutex (~40 bytes), `SpanData`
-> recordable (~250 bytes base), and `std::map`-based attribute storage (~200-500 bytes for 3-5
-> string attributes). See [Section 3.5.4](./03-implementation-strategy.md#354-performance-data-sources) for source references.
-
-**Network (10-50 KB/s) — Calculation**:
-
-Two sources of network overhead:
-
-**(A) OTLP span export to Collector:**
-
-| Sampling Rate              | Effective Spans/sec | Avg Span Size (compressed) | Bandwidth    |
-| -------------------------- | ------------------- | -------------------------- | ------------ |
-| 100% (dev only)            | ~500                | ~500 bytes                 | ~250 KB/s    |
-| **10% (recommended prod)** | **~50**             | **~500 bytes**             | **~25 KB/s** |
-| 1% (minimal)               | ~5                  | ~500 bytes                 | ~2.5 KB/s    |
-
-> The ~500 spans/sec at 100% comes from: ~100 TX spans + ~160 P2P context spans + ~23 consensus spans/round + ~50 RPC spans = ~500/sec. OTLP protobuf with gzip compression yields ~500 bytes/span average.
-
-**(B) P2P trace context overhead** (added to existing messages, always-on regardless of sampling):
-
-| Message Type  | Rate     | Context Size | Bandwidth     |
-| ------------- | -------- | ------------ | ------------- |
-| TMTransaction | ~100/sec | 29 bytes     | ~2.9 KB/s     |
-| TMValidation  | ~50/sec  | 29 bytes     | ~1.5 KB/s     |
-| TMProposeSet  | ~10/sec  | 29 bytes     | ~0.3 KB/s     |
-| **Total P2P** |          |              | **~4.7 KB/s** |
-
-> **Combined**: 25 KB/s (OTLP export at 10%) + 5 KB/s (P2P context) ≈ **~30 KB/s typical**. The 10-50 KB/s range covers 10-20% sampling under normal to peak mainnet load.
-
-**Latency (<2%) — Calculation**:
-
-| Path                           | Tracing Cost | Baseline | Overhead |
-| ------------------------------ | ------------ | -------- | -------- |
-| Fast RPC (e.g., `server_info`) | 2.75 μs      | ~1 ms    | 0.275%   |
-| Slow RPC (e.g., `path_find`)   | 2.75 μs      | ~100 ms  | 0.003%   |
-| Transaction processing         | 4.0 μs       | ~200 μs  | 2.0%     |
-| Consensus round                | 36 μs        | ~3 sec   | 0.001%   |
-
-> At p99, even the worst case (TX processing at 2.0%) is within the 1-3% range. RPC and consensus overhead are negligible. On production hardware, TX overhead drops to ~1.3%.
-
-### Per-Message Overhead (Context Propagation)
-
-Each P2P message carries trace context with the following overhead:
-
-| Field         | Size          | Description                               |
-| ------------- | ------------- | ----------------------------------------- |
-| `trace_id`    | 16 bytes      | Unique identifier for the entire trace    |
-| `span_id`     | 8 bytes       | Current span (becomes parent on receiver) |
-| `trace_flags` | 1 byte        | Sampling decision flags                   |
-| `trace_state` | 0-4 bytes     | Optional vendor-specific data             |
-| **Total**     | **~29 bytes** | **Added per traced P2P message**          |

-**Reading the diagram:**
-
-- **Original Message (gray, left)**: The existing P2P message payload of variable size — this is unchanged; trace context is appended, never modifying the original data.
-- **+ TraceContext (green, right of message)**: The additional 29-byte context block attached to each traced message; the arrow from the original message shows it is a pure addition.
-- **Context Breakdown (right subgraph)**: The four fields — `trace_id` (16 bytes), `span_id` (8 bytes), `flags` (1 byte), and `state` (0-4 bytes) — show exactly what is added and their individual sizes.
-- **Color coding**: Blue fields (`trace_id`, `span_id`) are the core identifiers required for trace correlation; orange (`flags`) controls sampling decisions; purple (`state`) is optional vendor data typically omitted.
-
-> **Note**: 29 bytes represents ~1-6% overhead depending on message size (500B simple TX to 5KB proposal), which is acceptable for the observability benefits provided.

-
-### Kill Switches (Rollback Options)
-
-1. **Config Disable**: Set `enabled=0` in config → instant disable, no restart needed for sampling
-2. **Rebuild**: Compile with `XRPL_ENABLE_TELEMETRY=OFF` → zero overhead (no-op)
-3. **Full Revert**: Clean separation allows easy commit reversion

-## Slide 9: Sampling Strategies — Head vs. Tail
-
-> Sampling controls **which traces are recorded and exported**. Without sampling, every operation generates a trace — at 500+ spans/sec, this overwhelms storage and network. Sampling lets you keep the signal, discard the noise.
-
-### Head Sampling (Decision at Start)
-
-The sampling decision is made **when a trace begins**, before any work is done. A random number is generated; if it falls within the configured ratio, the entire trace is recorded. Otherwise, the trace is silently dropped.

-| ----------------------------- | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- |
-| **Where it runs**             | Inside xrpld (SDK-level). Configured via `sampling_ratio` in `xrpld.cfg`.                                                                                                                                |
-| **When the decision happens** | At trace creation time — before the first span is even populated.                                                                                                                                        |
-| **How it works**              | `sampling_ratio=0.1` means each trace has a 10% probability of being recorded. Dropped traces incur near-zero overhead (no spans created, no attributes set, no export).                                 |
-| **Propagation**               | Once a trace is sampled, the `trace_flags` field (1 byte in the context header) tells downstream nodes to also sample it. Unsampled traces propagate `trace_flags=0`, so downstream nodes skip them too. |
-| **Pros**                      | Lowest overhead. Simple to configure. Predictable resource usage.                                                                                                                                        |
-| **Cons**                      | **Blind** — it doesn't know if the trace will be interesting. A rare error or slow consensus round has only a 10% chance of being captured.                                                              |
-| **Best for**                  | High-volume, steady-state traffic where most traces look similar (e.g., routine RPC requests).                                                                                                           |
-
-**xrpld configuration**:
-
-```ini
-[telemetry]
-# Record 10% of traces (recommended for production)
-sampling_ratio=0.1
-```
-
-### Tail Sampling (Decision at End)
-
-The sampling decision is made **after the trace completes**, based on its actual content — was it slow? Did it error? Was it a consensus round? This requires buffering complete traces before deciding.

-| **Where it runs**             | In the **OTel Collector** (external process), not inside xrpld. xrpld exports 100% of traces; the Collector decides what to keep.                                                                       |
-| **When the decision happens** | After the Collector has received all spans for a trace (waits `decision_wait=10s` for stragglers).                                                                                                      |
-| **How it works**              | Policy rules evaluate the completed trace: keep all errors, keep slow operations above a threshold, keep all consensus rounds, then probabilistically sample the rest at 10%.                           |
-| **Pros**                      | **Never misses important traces**. Errors, slow requests, and consensus anomalies are always captured regardless of probability.                                                                        |
-| **Cons**                      | Higher resource usage — xrpld must export 100% of spans to the Collector, which buffers them in memory before deciding. The Collector needs more RAM (configured via `num_traces` and `decision_wait`). |
-| **Best for**                  | Production troubleshooting where you can't afford to miss errors or anomalies.                                                                                                                          |

-| **Knows trace content?**      | No (random coin flip)                    | Yes (evaluates completed trace)                  |
-| **Overhead on xrpld**         | Lowest (dropped traces = no-op)          | Higher (must export 100% to Collector)           |
-| **Collector resource usage**  | Low (receives only sampled traces)       | Higher (buffers all traces before deciding)      |
-| **Captures all errors?**      | No (only if trace was randomly selected) | **Yes** (error policy catches them)              |
-| **Captures slow operations?** | No (random)                              | **Yes** (latency policy catches them)            |
-| **Configuration**             | `xrpld.cfg`: `sampling_ratio=0.1`        | `otel-collector.yaml`: `tail_sampling` processor |

-
-### Recommended Strategy for xrpld
-
-Use **both** in a layered approach:
-
-```mermaid
-flowchart LR
-    subgraph xrpld["xrpld (Head Sampling)"]
-        HS["sampling_ratio=1.0<br/>(export everything)"]
-    end
-
-    subgraph collector["OTel Collector (Tail Sampling)"]
-        TS["Keep: errors + slow + 10% random<br/>Drop: routine traces"]
-    end
-
-    subgraph storage["Backend Storage"]
-        ST["Only interesting traces<br/>stored long-term"]
-    end
-
-    xrpld -->|"100% of spans"| collector -->|"~15-20% kept"| storage
-
-    style xrpld fill:#424242,stroke:#212121,color:#fff
-    style collector fill:#1565c0,stroke:#0d47a1,color:#fff
-    style storage fill:#2e7d32,stroke:#1b5e20,color:#fff
-```
-
-> **Why this works**: xrpld exports everything (no blind drops), the Collector applies intelligent filtering (keep errors/slow/anomalies, sample the rest), and only ~15-20% of traces reach storage. If Collector resource usage becomes a concern, add head sampling at `sampling_ratio=0.5` to halve the export volume while still giving the Collector enough data for good tail-sampling decisions.

-## Slide 10: Data Collection & Privacy
-
-### What Data is Collected
-
-| Category        | Attributes Collected                                                                 | Purpose                     |
-| --------------- | ------------------------------------------------------------------------------------ | --------------------------- |
-| **Transaction** | `tx.hash`, `tx.type`, `tx.result`, `tx.fee`, `ledger_index`                          | Trace transaction lifecycle |
-| **Consensus**   | `round`, `phase`, `mode`, `proposers` (count of proposing validators), `duration_ms` | Analyze consensus timing    |
-| **RPC**         | `command`, `version`, `status`, `duration_ms`                                        | Monitor RPC performance     |
-| **Peer**        | `peer.id`(public key), `latency_ms`, `message.type`, `message.size`                  | Network topology analysis   |
-| **Ledger**      | `ledger.hash`, `ledger.index`, `close_time`, `tx_count`                              | Ledger progression tracking |
-| **Job**         | `job.type`, `queue_ms`, `worker`                                                     | JobQueue performance        |
-
-### What is NOT Collected (Privacy Guarantees)
-
-```mermaid
-flowchart LR
-    subgraph notCollected["❌ NOT Collected"]
-        direction LR
-        A["Private Keys"] ~~~ B["Account Balances"] ~~~ C["Transaction Amounts"]
-    end
-
-    subgraph alsoNot["❌ Also Excluded"]
-        direction LR
-        D["IP Addresses<br/>(configurable)"] ~~~ E["Personal Data"] ~~~ F["Raw TX Payloads"]
-    end

-    style E fill:#c62828,stroke:#8c2809,color:#fff
-    style F fill:#c62828,stroke:#8c2809,color:#fff
-```
-
-**Reading the diagram:**
-
-- **NOT Collected (top row, red)**: Private Keys, Account Balances, and Transaction Amounts are explicitly excluded — these are financial/security-sensitive fields that telemetry never touches.
-- **Also Excluded (bottom row, red)**: IP Addresses (configurable per deployment), Personal Data, and Raw TX Payloads are also excluded — these protect operator and user privacy.
-- **All-red styling**: Every box is styled in red to visually reinforce that these are hard exclusions, not optional — the telemetry system has no code path to collect any of these fields.
-- **Two-row layout**: The split between "NOT Collected" and "Also Excluded" distinguishes between financial data (top) and operational/personal data (bottom), making the privacy boundaries clear to auditors.
-
-### Privacy Protection Mechanisms
-
-| Mechanism                  | Description                                                   |
-| -------------------------- | ------------------------------------------------------------- |
-| **Account Hashing**        | `xrpl.tx.account` is hashed at collector level before storage |
-| **Configurable Redaction** | Sensitive fields can be excluded via config                   |
-| **Sampling**               | Only 10% of traces recorded by default (reduces exposure)     |
-| **Local Control**          | Node operators control what gets exported                     |
-| **No Raw Payloads**        | Transaction content is never recorded, only metadata          |
-
-> **Key Principle**: Telemetry collects **operational metadata** (timing, counts, hashes) — never **sensitive content** (keys, balances, amounts).

 [XRP](https://xrpl.org/xrp.html) is a public, counterparty-free crypto-asset native to the XRP Ledger, and is designed as a gas token for network services and to bridge different currencies. XRP is traded on the open-market and is available for anyone to access. The XRP Ledger was created in 2012 with a finite supply of 100 billion units of XRP.

 - Read [the levelization document](.github/scripts/levelization) to get an idea of the internal dependency graph.
 - In the big picture, the `main` function constructs an `ApplicationImp` object, which implements the `Application` virtual interface. Almost every component in the application takes an `Application&` parameter in its constructor, typically named `app` and stored as a member variable `app_`. This allows most components to depend on any other component.

+### Responsible Disclosure
+
+If you discover a vulnerability or potential threat, or if you _think_
+you have, please reach out by dropping an email using the contact
+information below.
+
+Your report should include the following:
+
+- Your contact information (typically, an email address);
+- The description of the vulnerability;
+- The attack scenario (if any);
+- The steps to reproduce the vulnerability;
+- Any other relevant details or artifacts, including code, scripts or patches.
+
+In your email, please describe the issue or potential threat. If possible, include a "repro" (code that can reproduce the issue) or describe the best way to reproduce and replicate the issue. Please make your report as detailed and comprehensive as possible.
+
+For more information on responsible disclosure, please read this [Wikipedia article](https://en.wikipedia.org/wiki/Responsible_disclosure).
+
+## Report Handling Process
+
+Please report the bug directly to us and limit further disclosure. If you want to prove that you knew the bug as of a given time, consider using a cryptographic pre-commitment: hash the content of your report and publish the hash on a medium of your choice (e.g. on Twitter or as a memo in a transaction) as "proof" that you had written the text at a given point in time.
+
+Once we receive a report, we:
+
+1. Assign two people to independently evaluate the report;
+2. Consider their recommendations;
+3. If action is necessary, formulate a plan to address the issue;
+4. Communicate privately with the reporter to explain our plan.
+5. Prepare, test and release a version which fixes the issue; and
+6. Announce the vulnerability publicly.
+
+We will triage and respond to your disclosure within 24 hours. Beyond that, we will work to analyze the issue in more detail, formulate, develop and test a fix.
+
+While we commit to responding with 24 hours of your initial report with our triage assessment, we cannot guarantee a response time for the remaining steps. We will communicate with you throughout this process, letting you know where we are and keeping you updated on the timeframe.

-We have partnered with Bugcrowd to manage this program. It is a private program, and security researchers can participate based on invitation. If you need access to the program, please email bugs@ripple.com with your Bugcrowd handle or Bugcrowd registered email, and we will get you added to the program. Once you have been added, please submit vulnerability reports through Bugcrowd, not by email. The detailed bug bounty policy is available on the Bugcrowd website.
+1. **In scope**. Only bugs in software under the scope of the program qualify. Currently, that means `rippled`, `xrpl.js`, `xrpl-py`, `xrpl4j`.
+2. **Relevant**. A security issue, posing a danger to user funds, privacy, or the operation of the XRP Ledger.
+3. **Original and previously unknown**. Bugs that are already known and discussed in public do not qualify. Previously reported bugs, even if publicly unknown, are not eligible.
+4. **Specific**. We welcome general security advice or recommendations, but we cannot pay bounties for that.
+5. **Fixable**. There has to be something we can do to permanently fix the problem. Note that bugs in other people’s software may still qualify in some cases. For example, if you find a bug in a library that we use which can compromise the security of software that is in scope and we can get it fixed, you may qualify for a bounty.
+6. **Unused**. If you use the exploit to attack the XRP Ledger, you do not qualify for a bounty. If you report a vulnerability used in an ongoing or past attack and there is specific, concrete evidence that suggests you are the attacker we reserve the right not to pay a bounty.
+
+The amount paid varies dramatically. Vulnerabilities that are harmless on their own, but could form part of a critical exploit will usually receive a bounty. Full-blown exploits can receive much higher bounties. Please don’t hold back partial vulnerabilities while trying to construct a full-blown exploit. We will pay a bounty to anyone who reports a complete chain of vulnerabilities even if they have reported each component of the exploit separately and those vulnerabilities have been fixed in the meantime. However, to qualify for a the full bounty, you must to have been the first to report each of the partial exploits.
