# Get Frame At

`GET /v1/sessions/{session_id}/frames/at/{captured_at_ms}`

Resolve a LOGICAL frame ref ({captured_at_ms}) to the stored frame —
the FrameSink resolver seam (docs/intent-streaming.md). Returns a 302 to
a freshly-presigned S3 URL, so references embedded in copied markdown
stay valid: the presign happens per-fetch, never baked into the artifact.
Capability-URL semantics (same as the join link). Nearest-match within
±2s tolerates the agent's capture-vs-persist timing skew.
