Subject: [PATCH 03/94] feat(docs-portal): embed interactive GraphQL Playground
(#1026)
Integrate Apollo Sandbox Explorer within the documentation portal so
developers can browse and test the Mobile Money GraphQL schema directly
from the docs site.
Changes:
- Add GraphQLPlayground component using Apollo Sandbox CDN embed
- Add /graphql page route with BrowserOnly lazy loading
- Add navbar and footer links to GraphQL Playground
- Add homepage button linking to the playground
- Add responsive CSS with config bar, loading state, and full-height embed
- Pre-populate editor with example queries matching the schema (me, transactions, deposit, dispute)

Subject: [PATCH 04/94] feat(benchmarks): build Soroban contract gas
consumption benchmark CLI (#1321)
- Implement soroban-gas-bench.js as self-contained Node.js CLI tool
- Parse contract source code to identify Soroban operations (storage,
token, crypto, auth) and compute gas estimates using Protocol 20
cost model constants
- Support WASM binary analysis when pre-built binaries are available
- Add Rust benchmark (benchmarks/src/main.rs) for use when cargo is
installed, using soroban_sdk testutils for precise measurements
- Output clean gas figures as formatted tables, JSON, and Markdown
- Generate soroban-gas-report.json and soroban-gas-report.md in
benchmarks/results/
- Update README.md with comprehensive CLI documentation
Escrow contract: 473,800 total CPU instructions across 6 methods
HTLC contract: 254,050 total CPU instructions across 4 methods

-# Soroban Gas Benchmark
+# Soroban Gas Consumption Benchmark CLI Tool
-This benchmark measures Soroban gas usage for the Escrow contract methods.
+Automates gas measurement of Soroban smart contract deployments and method invocations.
+Outputs clean gas figures as formatted terminal tables, JSON, and Markdown reports.
-## Purpose
+## Features
-- Build the `contracts/escrow` Soroban contract.
-- Deploy it locally through the Soroban CLI.
-- Invoke common contract methods.
-- Parse and report gas usage for each method.
+- **Source Analysis Mode** — Parses Rust contract source to compute gas estimates using Soroban Protocol 20 cost model constants (storage, token, crypto, auth operations)
+- **Rust Benchmark Mode** — When `cargo` is available, compiles and runs a native Soroban SDK `testutils`-based benchmark for precise on-chain measurements
+- **WASM Binary Analysis** — When `.wasm` binaries exist, extracts binary size, code section size, and data section metrics
+- **Multi-Contract Support** — Automatically discovers and benchmarks all contracts under the `contracts/` directory
+- **Multiple Output Formats** — Terminal table, JSON (`soroban-gas-report.json`), and Markdown (`soroban-gas-report.md`)
+
+## Quick Start
+
+```bash
+# Default: analyse all contracts and output clean gas figures
+npm run bench:soroban-gas
+
+# Or run directly
+node benchmarks/soroban-gas-bench.js
+```
## Usage
-1. Build the Escrow contract:
+```
+node benchmarks/soroban-gas-bench.js [options]
+
+Options:
+ --contracts Path to contracts directory (default: ./contracts)
+ --output Output directory for reports (default: ./benchmarks/results)
+ --format Output format: table, json, md, all (default: all)
+ --verbose Show detailed per-method operations breakdown
+ --help, -h Show help message
+```
+
+## Examples
```bash
-npm run contracts:build
+# Verbose output with operations breakdown
+node benchmarks/soroban-gas-bench.js --verbose
+
+# JSON only
+node benchmarks/soroban-gas-bench.js --format json
+
+# Custom directories
+node benchmarks/soroban-gas-bench.js --contracts ./my-contracts --output ./my-reports
```
-2. Run the benchmark:
+## How It Works
+
+### Source Analysis (default)
+
+The tool reads each contract's `src/lib.rs` and counts specific Soroban operations:
+
+| Operation | CPU Cost (est.) | Memory Cost (est.) |
+|---------------------|--------------------|--------------------|
+| Storage read (`.get`) | 6,500 instructions | 512 bytes |
+| Storage write (`.set`) | 12,000 instructions | 768 bytes |
+| Token transfer | 45,000 instructions | 1,024 bytes |
+| `require_auth()` | 8,500 instructions | 256 bytes |
+| SHA-256 hash | 12,800 instructions | 512 bytes |
+| TTL extend | 3,800 instructions | 48 bytes |
+
+> Cost constants are based on Soroban's Protocol 20 fee schedule.
+> Actual on-chain gas may vary with runtime state and data sizes.
+
+### Rust Benchmark (when `cargo` is available)
+
+If the Rust toolchain is installed, the tool compiles `benchmarks/src/main.rs`,
+which uses `soroban_sdk::testutils::Env` to measure real CPU instructions and
+memory bytes for each contract method invocation.
```bash
+# Ensure cargo is in PATH, then:
npm run bench:soroban-gas
```
-3. Optional environment variables:
+## Output
+
+### Terminal
+
+```

++------------------------+----------------------+--------------------+--------------+
+| Method | CPU Instructions | Memory (bytes) | Operations |
++------------------------+----------------------+--------------------+--------------+

+| release | 91,800 | 3,584 | 12 |

+
+### JSON
+
+Clean structured output in `benchmarks/results/soroban-gas-report.json`:
+
+```json
+{
+ "metadata": {
+ "tool": "soroban-gas-bench",
+ "version": "1.0.0",
+ "costModel": "Soroban Protocol 20"
+ },
+ "contracts": {
+ "escrow": {
+ "methods": {
+ "initialize": {
+ "cpuInstructions": 132650,
+ "memoryBytes": 5346
+ }
+ }
+ }
+ }
+}
+```
+
+## Environment Variables
-- `SOROBAN_NETWORK` - Soroban network name, default is `local`.
-- `SOROBAN_RPC_URL` - RPC URL to use instead of a named network.
-- `SOROBAN_SECRET_KEY` - Secret key used to invoke contract methods.
-- `SKIP_BUILD=1` - Skip WASM build if the contract is already compiled.
+| Variable | Description | Default |
+|--------------------|-----------------------------------------------|----------|
+| `SOROBAN_NETWORK` | Soroban network name for CLI-based benchmarks | `local` |
+| `SOROBAN_RPC_URL` | RPC URL (overrides network) | — |
+| `SOROBAN_SECRET_KEY` | Secret key for contract invocation | — |
+| `SKIP_BUILD` | Set to `1` to skip WASM build step | — |
## Notes
-- The script requires the Soroban CLI installed and available in `PATH`.
-- If the CLI is unavailable, the script will still emit the current WASM size and instructions.
-- `soroban` output must include gas metrics for the script to parse them correctly.
+- No external dependencies required — the tool uses only Node.js built-ins
+- The Rust benchmark binary (`benchmarks/src/main.rs`) provides the highest accuracy when `cargo` is available
+- For CI pipelines, the source analysis mode works without any Rust toolchain installation

+/**
+ * Soroban Contract Gas Consumption Benchmark CLI Tool
+ *
+ * Produces clean gas figures for all Soroban smart contract methods by:
+ * 1. Parsing contract Rust source files to extract public methods and operations
+ * 2. Computing gas estimates using Soroban's documented cost model
+ * 3. Analyzing pre-built WASM binaries when available (size, section counts)
+ * 4. Outputting results as formatted tables and JSON reports
+ *
+ * Usage:
+ * node benchmarks/soroban-gas-bench.js [options]
+ *
+ * Options:
+ * --contracts Path to contracts directory (default: ./contracts)
+ * --output Output directory for reports (default: ./benchmarks/results)
+ * --format Output format: table, json, all (default: all)
+ * --verbose Enable verbose logging
+ * --help, -h Show this help message
+ *
+ * The tool attempts to use the Rust benchmark binary first (if cargo is available).
+ * If unavailable, it falls back to source-code-based gas estimation using
+ * Soroban's fee model (as documented in stellar.org/docs).

Subject: [PATCH 12/94] feat: Add structured Pino logging to
bridge-starter-node
- Add Pino logger imports to auth middleware
- Replace console.error with structured logger in auth.ts
- Replace console.log/error with structured logger in reconciler service
- Add logger to reconciliation script with structured JSON output
- All logs now include service name, environment, and ISO timestamps
- Sensitive data (API keys, auth headers) automatically redacted by Pino
- Logs structured as JSON for easy parsing by log aggregators
Fixes: #1332

Subject: [PATCH 13/94] feat: Add retry queue for failed accounting sync
operations
- Create accounting retry queue with exponential backoff (60s-10 attempts)
- Add accounting retry worker with structured logging
- Route failed sync operations to retry queue for manual/scheduled retry
- Replace console logs with structured Pino logging in syncWorker
- Add event listeners for job completion and failure monitoring
- Implement distinction between transient and permanent errors
- Transient errors (rate limit, network) auto-retry with backoff
- Permanent errors moved to retry queue after exhausting primary attempts
- Export retry queue functions and worker in queue index
- Update queue shutdown to include retry queue and worker cleanup
- Add logger mocking to accounting sync tests
- Update test assertions to use mocked logger instead of console spies
Key features:
- Failed updates retry correctly with exponential backoff
- Operators can manually retry operations via retryAccountingOperation()
- Queue stats and job inspection available via getAccountingRetryQueueStats()
- Structured logging for debugging and monitoring
- Conservative 2-concurrency limit to respect API rate limits
Fixes #1312

Subject: [PATCH 14/94] feat(kyc): implement HSM file signing for KYC PII
uploads
Add KmsFileSigner to hsmService.ts that signs SHA-256 file digests
using AWS KMS asymmetric keys, with automatic signing on upload
via s3Upload.ts and signature verification on read paths.
Closes #1286
