Rewind / Workspace recovery

Keep useful checkpoints so an interrupted or failed run can resume without starting the workspace work again.

A concrete example

A long investigation fails after useful work

Input

The Athena workspace, checkpoint graph, task identity, retained branch, and authorised recovery request.

Action

Rewind selects the last useful checkpoint, restores that workspace state, and preserves the lineage.

Result

The run resumes with the retained files, context, checkpoint identity, and task record visible.

What you receive

// 01

Checkpoint graph

The retained workspace states and the lineage between them.

// 02

Restored workspace

The selected files and task context at the chosen point.

// 03

Resume record

The checkpoint identity, recovery decision, and resumed task state returned to Athena.

How it works

01
Retain useful state
Create workspace checkpoints as the task reaches points worth preserving.
02
Keep the lineage
Record how checkpoints branch and which state belongs to the current run.
03
Choose the last good point
Select the retained workspace state the authorised task should restore.
04
Resume with context
Return the restored workspace and checkpoint identity to Athena under the same task record.

Inside the mechanism

// 001

Content-addressed workspace state

Rewind retains checkpointed workspace material and metadata so the selected state can be identified and restored without replaying every earlier step.

// 002

Branch and lineage graph

The checkpoint graph records forks, parentage, and the state selected for the resumed task. Recovery therefore remains part of the same organisational account.

// 003

Measured replay boundary

The benefit depends on where an interruption occurs and how much prior workspace work a checkpoint preserves. The measured replay curve and its hard ceiling belong in the published methodology, not an unsupported headline.

What it proves

Bounded claim

Rewind can identify and restore the retained Athena workspace state represented by the selected checkpoint and preserve its lineage in the task record.

What it does not prove

Permanent boundary

Rewind restores workspace state. It does not reverse external effects. An email, payment, deployment, published commit, or other effect outside the workspace needs its own compensating action.

How it connects to Athena

Input

Workspace state, checkpoint metadata, task identity, branch graph, authority, and correlation identifier.

Output

Restored workspace reference, checkpoint identity, lineage, and resumed task state.

Shared record

Athena keeps the recovery request, selected checkpoint, restored state, resumed action, and later outcome connected.
