Live Reality Checks: Calendar TTLs Give Way to Source-Attested Evidence Across the Stack

Imagine a critical contract or configuration silently going stale because a background timer expired, not because the underlying source changed. Operators are left guessing whether the system's current state is truly valid, and developers must code around uncertain evidence. This kind of calendar-based TTL logic has been a friction point: it works until it doesn’t, and when it fails, it fails quietly. Today, that changes. The platform now cross-references live source control state and manifest reality, ensuring that what’s enforced is what’s actually present-no more silent staleness, no more guessing.

Why This Day Mattered

By tying contract validity and evidence checks directly to the live state of source repositories and manifests, the platform eliminates a longstanding blind spot: silent contract expiry due to calendar timeouts. Operators now get immediate, actionable evidence if a contract or manifest is out of sync with its source, while developers can rely on contracts being enforced only as long as the real, auditable source supports them. This closes the gap between configuration intent and runtime enforcement, making every approval and deployment safer and more predictable for users and operators alike.

What Actually Changed

A series of key contract and evidence validation flows, including weaver-canary, landscape/roadmap, and bundle-license, were refactored to replace calendar-based TTLs with live checks against the canonical Gitea SHA or manifest state. Instead of expiring based on elapsed time, these contracts now perform a real-time comparison with the current source, only marking themselves stale if the underlying reference is actually out of date. This shifts the platform from a timer-driven to a source-attested model, with validation logic that inspects the real, authoritative state before allowing or denying operations.

Why It Holds Better Now

Calendar TTLs can only approximate the freshness of a contract or manifest-they cannot guarantee that what's enforced matches what's current. By interrogating the live source state, the new mechanism ensures that evidence, approvals, and contract gates are always grounded in actual, up-to-date reality. This removes the risk of silent drift, eliminates the need for manual or periodic renewal, and makes contract enforcement both stricter and more transparent. Developers and operators can now trust that the platform’s decisions are driven by the real state, not by an arbitrary timer.
