Time Anchoring for Offline Environments

Module

AirGap

Status

IMPLEMENTED

Description

Time anchoring module with anchor loader, token parser, staleness calculator, and sealed startup validation for air-gapped environments. Includes HLC (Hybrid Logical Clock) merge services for multi-node sync.

Implementation Details

Time module: src/AirGap/StellaOps.AirGap.Time/ -- dedicated time anchoring service
Controllers: src/AirGap/StellaOps.AirGap.Time/Controllers/ -- time anchor API controllers
Services: src/AirGap/StellaOps.AirGap.Time/Services/ -- HLC merge, staleness calculation, anchor loading
Parsing: src/AirGap/StellaOps.AirGap.Time/Parsing/ -- time anchor token parsing
Models: src/AirGap/StellaOps.AirGap.Time/Models/ -- time anchor data models
Stores: src/AirGap/StellaOps.AirGap.Time/Stores/ -- time anchor state stores
Config: src/AirGap/StellaOps.AirGap.Time/Config/ -- time anchor configuration
Hooks: src/AirGap/StellaOps.AirGap.Time/Hooks/ -- time-related event hooks
Health: src/AirGap/StellaOps.AirGap.Time/Health/ -- time health checks
Fixtures: src/AirGap/StellaOps.AirGap.Time/fixtures/ -- deterministic time test data
Tests: src/AirGap/__Tests/StellaOps.AirGap.Time.Tests/
Attestor timestamping: src/Attestor/__Libraries/StellaOps.Attestor.Timestamping/TimeCorrelationValidator.Validate.cs, TimeCorrelationStatus.cs
Source: Feature matrix scan

E2E Test Plan

Verify time anchor loading from sealed bundles
Test token parsing extracts correct anchor timestamps
Test staleness calculator produces correct durations
Verify HLC merge service handles multi-node sync correctly
Test health checks report time anchor status
