Four projects preserve different parts of one durable work trajectory.

A capable model can finish one run while the user's larger task, accepted decisions, and unfinished work disappear with the session.

Preserves goals, tasks, accepted decisions, assignments, and completion evidence above replaceable model runs and local processes.

Shell commands and transient processes do not preserve enough identity or evidence for a later agent to know what actually happened.

Turns admitted local operations into durable jobs, observable process state, bounded output, artifacts, cancellation, and restart recovery.

An external action can lose its response while paths, identities, and provider conditions change, making a blind retry unsafe.

Correlates target, path, identity, authority, provider execution, receipts, observations, uncertainty, reconciliation, and rebinding around one external interaction.

Agent systems can accumulate shared abstractions faster than real workloads justify them.

Compares proposed contracts against mature baselines and keeps only the responsibilities that survive replacement, interruption, and a deletion test.
