feat(domain): add configuration audit trail with diff detection and rollback by igormorais123 · Pull Request #796 · diegosouzapw/OmniRoute

igormorais123 · 2026-03-30T03:49:32Z

Summary

Add configAudit.ts to src/domain/
Record every change to providers, combos, policies, and connections
Compute structured diffs (added/removed/changed keys)
Track change source (dashboard, API, sync, auto-healing, CLI, MCP)
Enable rollback via getRollbackState(entryId)
Support configuration snapshots for export/import

Motivation

When a routing config change causes failures, there's currently no way to:

See what changed and when
Compare current config vs. a known-good state
Rollback to a previous working configuration

This is critical after provider cleanups (disabling dead connections) or combo reordering — operations that can silently break routing.

API

// Record a change
recordChange('update', 'combo', 'coding-power', 'Coding Power', 
  { models: ['codex', 'opus'] },        // before
  { models: ['codex', 'sonnet', 'opus'] }, // after
  'dashboard',
  'Added sonnet as second fallback'
);

// Query audit log
const { entries, total } = getAuditLog({ target: 'combo', limit: 20 });

// Rollback: get state before a change
const previousState = getRollbackState(entry.id);

// Export snapshot
const snapshot = createSnapshot('v4.1', 'Before cleanup', fullConfig);

// Summary
const summary = getAuditSummary();
// → { totalEntries: 47, byTarget: { combo: 12, provider: 35 }, ... }

Issue Details (click to expand)

CRITICAL

File	Line	Issue
`src/domain/configAudit.ts`	80	ID Collision Risk: The `generateId()` function uses `idCounter++` which will eventually overflow. While the counter uses base-36 and padStart(4, "0"), there's no protection against the counter wrapping or multiple server instances generating the same IDs. Consider using `crypto.randomUUID()` or include a server-specific prefix.

WARNING

File	Line	Issue
`src/domain/configAudit.ts`	73-74	Incorrect oldest/newest timestamps in getAuditSummary(): The code returns `auditLog[0]` and `auditLog[auditLog.length - 1]` as oldest/newest, but the log is sorted by newest first when entries are added. Since entries are pushed and then sliced, the oldest entry is actually at the END of the array, not the beginning. The function should iterate to find min/max timestamps instead.

| src/domain/configAudit.ts | 161 | Missing input validation: The targetId parameter in recordChange() has no length or format validation. Consider adding bounds checking to prevent extremely long IDs from being stored.

| src/domain/configAudit.ts | 73 | In-memory storage limitation: The audit log is stored in-memory and will be lost on server restart. While this is documented in a comment, it poses a risk in production environments where audit trail persistence is critical for troubleshooting. Consider integrating with the SQLite database layer used elsewhere in the codebase.

Code Review

This pull request introduces a configuration audit trail system in src/domain/configAudit.ts to track changes to entities like providers and policies with before/after snapshots. Key feedback includes replacing the counter-based ID generation with UUIDs for better reliability, using a more robust deep comparison method instead of JSON.stringify for computing diffs, and optimizing the in-memory log bounding logic by using shift() instead of slice().

src/domain/configAudit.ts

+let idCounter = 0;
+
+function generateId(): string {
+  idCounter++;
+  const ts = Date.now().toString(36);
+  const seq = idCounter.toString(36).padStart(4, "0");
+  return `audit-${ts}-${seq}`;
+}


The current generateId implementation using a simple idCounter is not robust. It's not guaranteed to be unique across application restarts or in a concurrent environment. A better approach is to use a universally unique identifier.

I suggest using crypto.randomUUID(), which is built into modern Node.js versions (v14.17.0+). This removes the need for idCounter and is much more reliable.

Suggested change

let idCounter = 0;

function generateId(): string {

idCounter++;

const ts = Date.now().toString(36);

const seq = idCounter.toString(36).padStart(4, "0");

return `audit-${ts}-${seq}`;

}

// idCounter is no longer needed when using UUIDs.

function generateId(): string {

// Using crypto.randomUUID() for globally unique identifiers.

// This is more robust than a timestamp-based counter.

// Add `import { randomUUID } from 'node:crypto';` to file imports.

return `audit-${randomUUID()}`;

}

+      const beforeVal = before![key];
+      const afterVal = after![key];
+      if (JSON.stringify(beforeVal) !== JSON.stringify(afterVal)) {


Using JSON.stringify for object comparison can be unreliable. The order of object keys is not guaranteed in JavaScript, which can lead to different JSON strings for semantically identical objects (e.g., {a:1, b:2} vs {b:2, a:1}).

For more robust deep object comparison, consider using a library like lodash.isEqual.

src/domain/configAudit.ts

+  if (auditLog.length > 1000) {
+    auditLog = auditLog.slice(-1000);
+  }


To keep the log bounded, the current code uses auditLog.slice(-1000). This creates a new array of up to 1000 elements every time an entry is added beyond the limit, which can be inefficient. Since entries are added one by one, a more performant approach is to simply remove the oldest element using auditLog.shift().

Suggested change

if (auditLog.length > 1000) {

auditLog = auditLog.slice(-1000);

}

if (auditLog.length > 1000) {

auditLog.shift();

}

src/domain/configAudit.ts

+    before,
+    after,


Clone before/after snapshots when recording changes

recordChange stores before and after by reference, so later mutations to the original config objects rewrite historical audit entries and invalidate rollback data. This breaks the core audit-trail guarantee in common flows where callers reuse mutable config objects (e.g., update object then pass it through additional transformations). Store deep-cloned snapshots at write time so history remains immutable.

+export function getRollbackState(entryId: string): Record<string, unknown> | null {
+  const entry = getAuditEntry(entryId);
+  if (!entry) return null;
+  return entry.before;


Return a copy from rollback state access

getRollbackState returns the internal entry.before object directly, which lets callers mutate the audit log by editing the returned value. After one rollback attempt that modifies this object, future rollbacks and log inspection can be silently corrupted. Return a cloned snapshot instead of the in-memory reference.

Useful? React with 👍 / 👎.

Use structural compare instead of JSON stringify diff

Diff detection currently uses JSON.stringify equality, which is order-sensitive for object keys. Two semantically identical configs with different key insertion order will be marked as changed, producing noisy or misleading audit entries and potentially triggering unnecessary rollback decisions. Use a stable deep-equality check that ignores key ordering for plain objects.

Useful? React with 👍 / 👎.

Olá, Professor Igor! Muito obrigado pela iniciativa fenomenal! 🕵️‍♂️📝

Manter um log de auditoria (Audit Trail) contra mudanças que possam quebrar as políticas e o fluxo de proxy é uma feature muito aguardada, especialmente pensando em rollbacks de configurações falhas!

Para transformarmos este conceito genial em uma feature de produção pronta para o OmniRoute, analise as sugestões abaixo para ajustarmos este Pull Request:

Pontos de Adaptação (Padrão de Arquitetura)

O Log de Auditoria precisa sobreviver a reinícios (SQLite)
Atualmente a variável let auditLog: ConfigAuditEntry[] = []; mora unicamente em memória volátil. Devido ao ciclo de vida do proxy, configurações em runtime são perdidas quando o container/processo reinicia.
O que fazer: Crie um modulo de banco de dados (src/lib/db/audit.ts) ou integre ao banco existente gerenciado em src/lib/db/core.ts. Todas as gravações recordChange devem fazer um INSERT seguro. Isso protegerá nosso log de auditoria persistentemente.
Integração Real com o Core App
Assim como um bom livro na prateleira precisa ser lido, o seu código precisa ser usado pelo sistema. Atualmente as funções recordChange(), getAuditLog() e getRollbackState() estão perfeitamente definidas... mas não possuem nenhum apelador.
O que fazer: Integre a função recordChange nos endpoints de Update de Providers/Combos reais. (Para fins didáticos, você pode adicioná-lo dentro de src/app/api/settings/route.ts ou funções que salvam provedores no banco).
Cobertura de Testes (Faltante)
Seu checklist aponta os testes como desenvolvidos, porém nenhum arquivo .test.ts foi adicionado à remessa ou ao diff. Certifique-se de realizar o commit do seu arquivo de teste unitário.

Por favor, faça essas adições arquiteturais e atualize sua branch feat/config-audit-trail. A sua lógica de diff computation (keys modified/added/removed) é fantástica, estamos ansiosos para aplicar esse código na infraestrutura quando as integrações passarem! Um super abraço! 🤝
