Audit follow-up. After verifying the codebase, three exports of
retry-utils.ts have ZERO production callers:
- `withRetry` decorator (lines 419-440): unused
- `retryable` wrapper (lines 442-453): unused (1 self-test only)
- `RetryManager` class (lines 455-549): unused (1 self-test only)
Note: `MessageRetryManager` in messages-send.ts is a separate class,
not the same thing.
The kept exports are still used:
- `retry()` function: used by decode-wa-message.ts for Bad MAC recovery
- `RetryExhaustedError`, `RetryOptions`, `RetryContext`: used same place
- `RETRY_BACKOFF_DELAYS`, `RETRY_JITTER_FACTOR`: re-exported via Defaults
- `retryPredicates`, `retryConfigs`: helper presets (kept; small)
Removed `EventEmitter` import (was only used by the deleted RetryManager).
Removed `retryable` and `RetryManager` from test imports + their describe
blocks (5 tests removed, all targeting the deleted code).
Net: -148 lines from retry-utils.ts, -90 lines from its test file.
803 tests pass (was 809; 6 deleted tests covered the removed code).
Now the InfiniteAPI retry surface is:
- `retry-utils.ts:retry()` for Bad MAC recovery (decryption layer)
- `bounded-retry.ts:withBoundedRetry()` for socket operation retry
(uploadPreKeys), with WhatsApp Android empirical defaults
No redundancy: each helper handles a distinct concern.
Applied yarn lint --fix to auto-correct:
- Import spacing and sorting across multiple files
- Trailing commas
- Arrow function formatting
- Object literal formatting
- Indentation consistency
- Removed unused imports (BaileysEventType, jest from tests)
This commit addresses the linting errors reported in GitHub Actions:
- Fixed import ordering in libsignal.ts
- Fixed trailing commas in Defaults/index.ts
- Cleaned up formatting across 63 files
- Reduced line count by ~220 lines through formatting optimization
Note: Some lint errors remain (75 errors, 239 warnings) mainly:
- @typescript-eslint/no-unused-vars (variables assigned but not used)
- @typescript-eslint/no-explicit-any (type safety warnings)
These remaining issues are non-blocking and can be addressed incrementally.

Prometheus Metrics:
- Add METRICS_LABELS fallback for defaultLabels env config
- Separate includeSystem from collectDefaultMetrics with own env var
- Parse URL in /metrics endpoint to support querystrings and trailing slashes
- Sort keys in labelsToKey for stable/deterministic lookups
- Update documentation with all environment variables
Retry Utils:
- Remove abort listener on sleep completion to prevent memory leak
- Apply maxDelay cap AFTER jitter to guarantee max delay limit
- Validate/normalize attempt parameter in calculateDelay
- Count retries only when attempt > 1 (actual retry, not first try)
- Use metrics.retryExhausted instead of generic errors for exhausted retries
Tests:
- Add consistency tests to verify retryConfigs.rsocket matches constants
