Accept
Only local ZIP files beginning with a documented HEL-* bundle identifier, within explicit size and file-count limits.
ATLAS HELIOS
Methodology
The website accepts versioned, validated Memory Bridge exports and preserves unavailable data as unavailable.
READ-ONLY · LOCAL
Validate
Reject traversal paths, unsupported entries, malformed ZIP structures, mismatched IDs, unknown schemas, and failed SHA-256 checks.
Normalize
Map schema 1.0, 1.1, and 1.2 fields to their versioned web snapshots. Missing optional fields become null; raw source records are never published.
Render
Render only normalized local snapshots. Markdown, personal notes, canonical-state payloads, device paths, and raw records are excluded.
PERSISTED OBSERVATIONS, NOT CONTINUOUS MEASUREMENT
A Signature History record is an immutable persisted AtlasSolarState paired with its Helios Signature. Repeated signatures remain separate observations. A signature change and a phase change are counted only from exported persisted records; transition relationships come only from persisted StateTransition records. The Android model stores observation times but no explicit state duration. The website may derive an observed interval only to the next persisted evaluation, never across a gap longer than the one-hour application freshness limit, and the final record remains open-ended.
ONE-HOUR ANDROID UI LIMIT
The website applies the Android primary-screen rule: the aggregate dashboard timestamp is stale only after observation time plus 3,600 seconds. Exactly at the limit it remains fresh. The export contains one aggregate timestamp and no per-field timestamps or collection-interval setting, so the website does not claim field-level freshness.
HASH VERIFIED · SENDER SIGNATURE NOT AVAILABLE
Manifest SHA-256 checks establish consistency between the listed payload and the imported files. They do not authenticate the sender. Helios Signature is a deterministic solar-state identifier, not a cryptographic signature. Scientific values remain attributed to NOAA data carried by the Atlas Helios export.
NO NETWORK TRANSPORT
This phase does not contact NOAA, NASA, Android, Atlas Home, or a Linux VPS. A physical-phone schema 1.2 export is not created or imported in this phase.
