Bird Troubleshooting

  Diagnose active BIRD daemon incidents across config, runtime, environment,
  sockets, logs, source, and tooling. Use when BIRD fails to start or reload,
  crashes, loses sessions/routes, behaves differently after lint passes, or
  when birdcc and bird -p disagree. Collect read-only evidence first, protect
  routing secrets, and route isolated config edits to bird-agent or pure
  implementation research to bird-source-explorer.

# BIRD Troubleshooting

Determine whether the failure is discovery, static analysis, native parsing, runtime state,
environment, or an upstream implementation defect.

## Safety

- Start read-only. Do not reload, reconfigure, restart, kill, or attach a debugger to production
  BIRD without explicit authorization.
- Redact passwords, peer IPs, private ASNs, communities, socket paths, and policy details before
  sharing output.
- Treat custom `validateCommand` values and workspace scripts as executable code. Show them before
  running in an untrusted checkout.
- Preserve exact error text and timestamps, but do not dump whole production configs or logs.

## Workflow

1. Run:

   ```bash
   uv run scripts/collect_diagnostics.py --root .
   ```

   Read [`references/troubleshooting-workflow.md`](references/troubleshooting-workflow.md) for
   interpretation.
2. Establish BIRD version/build, selected config entry, project config, binary paths, the exact
   failing command, and last known good state.
3. Reproduce at the narrowest read-only layer:
   - discovery → `birdcc init . --dry-run --json`;
   - static/cross-file → `birdcc lint <entry> --json`;
   - native parse → matching `bird -p -c <entry>`;
   - live state → user-approved read-only `birdc show ...` commands.
4. If lint fails, route the fix through `bird-agent`. If lint succeeds but native parse fails,
   compare binary version, includes, generated inputs, permissions, and environment.
5. If parsing succeeds but runtime behavior is wrong, correlate logs and live state before using
   `bird-source-explorer` on the matching source revision.
6. Present ranked hypotheses with evidence, a falsifying check, and operational risk for each.

## Completion

Confirm:

- baseline evidence and exact versions were collected;
- static, native-parse, and runtime layers were not conflated;
- the leading cause has direct evidence or is labeled a hypothesis;
- the next command is read-only or explicitly marked as mutating;
- secrets were not exposed;
- rollback or recovery impact is stated before any proposed operational change.
