INTEGRATIONS // ZERO-INSTRUMENTATION

Zero-Instrumentation Forensics.

Déjà connects to observability, source control, and audit systems to build a deterministic CHAIN_OF_CUSTODY — without agents, SDKs, or code changes. Every uplink is auditable. Every match is provable.

Verified Uplinks

Each integration is treated as a hardened perimeter connection. Status indicates readiness to ingest, fingerprint, and correlate.

Chain of Custody

Three Columns of Custody

Evidence flows from telemetry to verification to audit reporting — preserving the exact path from incident signal to verified fix.

The Core Stack

Deterministic links across your toolchain

Déjà is the deterministic bridge between systems that REPORT failures and systems that PROVE fixes.

Source control

Repository fingerprinting

Identify the exact PR / commit that resolved an incident and persist proof that survives refactors and turnover.

Observability

Real-time signals

Ingest errors and releases via webhooks. No agents. No SDKs. No runtime overhead.

Why Déjà integration is different

Hardened continuity — zero performance impact

Traditional tools require instrumentation. Déjà operates as a secure pass-through analysis layer. If Déjà is unavailable, your services keep running.

UPLINK_STABILITY: VERIFIED

Your production performance is safe.

We ingest via async webhooks + read-only APIs. No inline request interception. No agents on hosts.

LIVE_LATENCY: ~0ms (out-of-band)

Ingestion lanes

Dual-lane ingestion

> LANE_1 (historical): backfill_window = 730_days
> LANE_2 (real_time): webhook_stream = enabled
> GUARANTEE: no_runtime_hooks // no_sidecars

Permissions

Least privilege access

  • pull_requests:read
