known_gaps:
  - Memory analysis depends on garbage collector timing, retained object paths, native memory, allocator behavior, container limits, browser process boundaries, and whether the snapshot captures a steady leak or a temporary cache.
  - Heap snapshots can include sensitive data from prompts, documents, environment values, and user sessions, so sharing them requires redaction.

## TL;DR

Heap snapshots and allocation traces help agents decide whether memory growth is a leak, cache, batch-size problem, browser artifact, or runtime configuration issue.

## Core Explanation

Agent systems often process large documents, screenshots, embeddings, traces, and JSON payloads. Memory failures can appear as slowdowns, out-of-memory exits, browser tab crashes, or container restarts. A heap snapshot or allocation trace gives a stronger explanation than a single memory gauge.

Useful evidence includes runtime version, heap limit, container memory limit, snapshot time, workload, retained object classes, allocation stack, object counts, external memory, garbage collection events, and comparison against a baseline snapshot. Agents should connect the retained objects to an owner such as cache, queue, parser, browser page, vector batch, or request trace.

Memory evidence can be sensitive. Prompts, retrieved documents, tokens, and user data may be present in snapshots, so agents should summarize findings and avoid exposing raw dumps unless the workflow explicitly permits it.
