Systematic Debugging

When to Use

Invoke this methodology automatically when:

A test fails and the cause isn't immediately obvious
Unexpected behavior occurs in production or development
An error message doesn't directly point to the fix
Multiple potential causes exist

Core Principles

Hypothesize before acting - Form explicit hypotheses about root cause before changing code
Test hypotheses systematically - Validate or eliminate each hypothesis with evidence
Parallelize investigation - Use subagents for concurrent readonly exploration
Preserve test integrity - Never weaken tests to make them pass

Debugging Scope Ladder

Always prefer the smallest, most reproducible scope that demonstrates the bug. Work up the ladder only when the smaller scope can't reproduce or doesn't apply:

Priority	Scope	When to Use	Command
1	Unit test	Logic errors, algorithm bugs, single-function issues	`cargo test -p freenet -- specific_test`
2	Mocked unit test	Transport/ring logic needing isolation	Unit test with `MockNetworkBridge` / `MockRing`
3	Simulation test	Multi-node behavior, state machines, race conditions	`cargo test -p freenet --test simulation_integration -- --test-threads=1`
4	SimNetwork + FaultConfig	Fault tolerance, message loss, network partitions	SimNetwork with configured fault injection
5	fdev single-process	Quick multi-peer CI validation	`cargo run -p fdev -- test --seed 42 single-process`
6	freenet-test-network	20+ peer large-scale behavior	Docker-based `freenet-test-network`
7	Real network	Issues that only manifest with real UDP/NAT/latency	Manual multi-peer test across machines

Why this order matters:

Lower scopes are faster, deterministic, and reproducible by anyone
Higher scopes require more infrastructure, time, and may not be accessible to all contributors
Gateway logs, aggregate telemetry, and production metrics are not available to every developer — don't assume access to these when designing reproduction steps

Debugging Workflow

Phase 0: Claim the Issue

If you're working on a GitHub issue, check if it's already assigned before starting. If someone else is assigned, stop and inform the user — don't duplicate effort. If unassigned, assign it to yourself so others know it's being worked on:

gh issue view <ISSUE> --repo freenet/<REPO>  # Check assignees
gh issue edit <ISSUE> --repo freenet/<REPO> --add-assignee @me

Phase 1: Reproduce and Isolate

Reproduce the failure — Confirm the bug exists and is reproducible
Use the scope ladder — Start at the smallest scope that can demonstrate the bug:
- Can you write a unit test? Try that first
- Needs multiple nodes? Use the simulation framework with a deterministic seed
- Only happens under fault conditions? Use SimNetwork with FaultConfig
- Can't reproduce in simulation? Then escalate to real network testing
Record the seed — When using simulation tests, always record the seed value for reproducibility
Gather initial evidence — Read error messages, logs, stack traces

Simulation-first approach for distributed bugs:

# Run simulation tests deterministically
cargo test -p freenet --features simulation_tests --test sim_network -- --test-threads=1

# With logging to observe event sequences
RUST_LOG=info cargo test -p freenet --features simulation_tests --test sim_network -- --nocapture --test-threads=1

# Reproduce with a specific seed
cargo run -p fdev -- test --seed 0xDEADBEEF single-process

Phase 1b: When the Bug Is Reported from the Live Network

When a bug comes from production observations (user reports, telemetry, monitoring), the goal is to translate the network observation into a local reproduction as fast as possible. Live-network debugging has the slowest feedback loop — adding telemetry, redeploying, waiting — so minimize time spent there.

The workflow:

Constrain the problem from network data — What operation type? Which peers? What hop count? What timing pattern? Use telemetry or user reports to narrow this down.
Translate constraints into simulation parameters:

Network Observation	Simulation Translation
"GET times out at hop 3"	`#[freenet_test]` with 4+ nodes, specific `node_locations` matching topology
"Peer X never responds"	Node configured to drop/delay messages via `FaultConfig`
"73% timeout rate"	`FaultConfig { message_loss_rate: 0.7, .. }` or unresponsive target node
"Works for PUT but not GET"	Test both operations — likely incomplete wiring in dispatch path
"Rapid connect/disconnect cycles"	Simulation with transport-level fault injection
"Messages dropped after acknowledgement"	`FaultConfig` with selective message loss after initial handshake

Write the simulation test — Start with #[freenet_test] or SimNetwork + FaultConfig. Use a deterministic seed.
Debug locally — Now iterate with full control: add tracing, assertions, state inspection. No redeployment needed.
Validate — Optionally confirm via telemetry that the deployed fix improves live behavior.

If a telemetry-monitor skill is available (project-local, not part of this plugin), use it to query the centralized OpenTelemetry collector for constraining the problem. But treat telemetry as input to simulation design, not as the primary debugging tool.

Resist the temptation to keep adding telemetry to find the root cause. Once you know what fails (operation type, peer pattern, timing), stop analyzing network data and reproduce locally. The simulation feedback loop is orders of magnitude faster.

Phase 2: Form Hypotheses

Before touching any code, explicitly list potential causes:

Hypotheses:
1. [Most likely] The X component isn't handling Y case
2. [Possible] Race condition between A and B
3. [Less likely] Configuration mismatch in Z

Rank by likelihood based on evidence. Avoid anchoring on the first idea.

Freenet-specific hypothesis patterns:

State machine bugs — Invalid transitions in operations (CONNECT, GET, PUT, UPDATE, SUBSCRIBE)
Ring/routing errors — Incorrect peer selection, distance calculations, topology issues
Transport issues — UDP packet loss handling, encryption/decryption, connection lifecycle
Contract execution — WASM sandbox issues, state verification failures
Determinism violations — Code using std::time::Instant::now() instead of TimeSource, or rand::random() instead of GlobalRng
Silent failure / fire-and-forget — Spawned task dies with no error propagation (check: is the JoinHandle stored and polled? what happens if the task exits?), broadcast sent to zero targets with no warning, channel overflow silently dropping messages. Look for: tokio::spawn without .await/.abort(), let _ = sender.send(), missing logging on empty target sets
Resource exhaustion — HashMap/Vec/channel entries inserted but never removed, causing unbounded memory growth or channel backpressure. Check: is there a cleanup path for every insert? Is cleanup triggered on both success AND failure/timeout? Run sustained operations and assert collection sizes stay bounded
Incomplete wiring — Feature only works for some operation types (e.g., router feedback wired for GET but not subscribe/put/update). When debugging "X doesn't work for operation Y," check all enum variants in the dispatch path — commented-out arms, _ => Irrelevant catch-alls, and missing match arms are common
TTL/timing race conditions — Two time-dependent operations where the first can expire before the second completes (e.g., transient TTL expires before CONNECT handshake, interest TTL expires before subscription renewal, broadcast fires before subscriptions complete). Check: what happens if operation A takes longer than timeout B?
Regressions from "safe" changes — A seemingly harmless change (code simplification, removing a feature flag, changing defaults) breaks an invariant that nothing tests. When a recent commit looks innocent, check what implicit behaviors it removed
Mock/test divergence — Bug can't be reproduced in tests because the mock runtime behaves differently from production. Check: does the mock skip side effects (e.g., BSC emission)? Does the test use a different code path than production (e.g., explicit subscribe vs background subscribe)? Does the mock socket behave differently from real UDP?

See Module-Specific Debugging Guide for detailed bug patterns, data collection strategies, and test approaches per module.

Phase 3: Investigate Systematically

For each hypothesis:

Identify what evidence would confirm or refute it
Gather that evidence (logs, code reading, adding debug output)
Update hypothesis ranking based on findings
Move to next hypothesis if current one is eliminated

Freenet-specific data gathering:

What You Need	How to Get It	Access
Event sequences	`RUST_LOG=info` + `--nocapture` on simulation tests	Everyone
Network message patterns	`sim.get_network_stats()` in simulation tests	Everyone
Convergence behavior	`sim.await_convergence(timeout, poll, min_contracts)`	Everyone
Virtual time state	`sim.virtual_time().now_nanos()`	Everyone
Git history of affected code	`git log --oneline -20 -- path/to/file.rs`	Everyone
Fault injection results	SimNetwork + FaultConfig, then inspect stats	Everyone
Gateway logs	Access to running gateway node	Limited — not all contributors
Aggregate telemetry	`telemetry-monitor` skill (if available) or production dashboards	Limited — core team only
Real network packet captures	Physical access to test machines	Limited — specific environments

Note on telemetry: If a telemetry-monitor skill is available in the project, use it to query network telemetry for constraining the problem (see Phase 1b). But remember: telemetry constrains, simulation reproduces. Don't spend cycles iterating on telemetry queries when you have enough information to write a simulation test.

Asserting on freenet-core logs from E2E tests: use structured fields, not wire-level markers. Modern freenet-core (0.2.6x and later) emits tracing output as structured fields — phase="update_complete", phase="relay_started", op="GET", tx="01KK70…". Legacy wire-level grep markers (UPDATE_PROPAGATION, OP_FORWARDED, etc.) that older tests and tutorials reference have been removed. An E2E test that greps for them will pass forever — the line will never appear, so the negative assertion is vacuously true, and the test gives a false green.

When writing or fixing an E2E log assertion against a freenet node:

Tail the log directly with the same RUST_LOG you'll use in CI and read what's actually emitted around the event you care about. Don't copy a grep pattern from an old test.
Match on the structured field shape — phase="<value>" is the most stable; transaction IDs (tx=) are good for following a single op across nodes.
Treat log assertions as supplementary. The authoritative check that the system reached a state is the UI assertion (Playwright sees the message in the recipient's inbox) or a contract GET vi
