live-session-truth-layer

Telemetry Boundary Layer

Session truth layer showing what is directly observed, what is reducer-derived, and what remains outside current coverage.

Skill Proof Run

wf1 · proving the new visualization sketch grammar against the same brief set we will rerun later.

Live network/session topology with partial file/process coverage. Missing items are not proof of inactivity.

Coverage Breakdown

proxy

durable primary

observed

Strongest current network truth. Supplies host, request timing, and repeated-flow volume.

bridge

file attribution

partial

Provides direct file touches when available, but coverage can drop for short-lived or indirect access.

discover

context fill

reduced

Helps classify endpoint and process context, but is not always the authoritative source for session semantics.

reducer

session abstraction

inferred

Merges repeated low-level records into clusters, flows, and session-level shape.

Selected Item Evidence

Authority

Primary semantic source: `proxy`

Reducer agrees with host identity. No conflicting labels from discover.

Correlation Keys

session_id · request_id cluster · host label normalization

Known Boundary Notes

Missing does not mean safe

A missing file or process may fall outside current telemetry rather than indicating inactivity.

Reducer-derived clusters are useful, but second-order truth

Keep them visible and useful while clearly signaling that they summarize evidence rather than replace it.

Boundary language belongs near the canvas

Users should not have to hunt through documentation to understand what is and is not represented in the current session view.
