Mode 0 — Archive Replay
Surviving records are replayed with provenance and transformation history intact.
A receive-only historical observation architecture separating archive replay, reconstruction, and canonical temporal-aperture modes while preserving provenance, privacy, uncertainty, and non-interference.

The Temporal Viewer is a governed observation service, not a generic window into the past. Every session identifies whether the image is archive replay, physics-based reconstruction, or a canonical aperture observation, and every mode carries provenance, uncertainty, privacy, and causal-coupling limits.
Surviving records are replayed with provenance and transformation history intact.
Surviving signals and environmental evidence can constrain a reconstruction, but inferred content remains visibly labeled.
Fictional receive-only apertures require an authenticated event address, causal isolation, return-channel monitoring, and safe collapse.
Transforms an authenticated historical target into the active reference frame and rejects ambiguous epochs.
Prevents observation sessions from becoming communication, navigation, market, military, or warning channels.
Records raw acquisition, reconstruction versions, uncertainty masks, operator actions, session mode, and closure telemetry.


Temporal observation can defeat ordinary expectations of privacy and can expose witnesses to grief, atrocity, lost family, personal ancestry, or earlier versions of themselves. Minimum necessary observation, cultural custody, clinical safeguards, and refusal authority are therefore part of the system architecture rather than afterthoughts.
