Handoff sequencePlan a rolling-origin task forecast evaluation
Keep each held-out outcome beyond its own fitting cutoff while matching a fixed forecast horizon.
The artifact plans repeated prospective cutoffs at a fixed horizon, rather than a single held-out split or hindsight replacement.

Put the outline to work
- Freeze each origin boundary. Check: Every prediction has its own allowed information cutoff.
- Match the evaluation horizon. Check: All three target records describe one-step predictions.
- Retain genuine origin forecasts. Check: Later fits do not overwrite the saved earlier predictions or their input boundaries.

01 · Inspect the inputs
Every record stays visible
| Forecast origin | Allowed observations | Held-out target | Horizon |
|---|---|---|---|
| Day 3 | Days 1–3 | Day 4 | One step |
| Day 4 | Days 1–4 | Day 5 | One step |
| Day 5 | Days 1–5 | Day 6 | One step |

How the case leads to a decision
There are three prospective origin/target pairs. At each origin, the target day is excluded from fitting; earlier observed targets can become allowed history at a later origin.
The bounded result
Each outcome stays beyond its own fitting cutoff while the one-step horizon remains fixed. Keep all three origins rather than letting a later fitted rule retrospectively see earlier held-out outcomes.

Make each handoff explicit
Sequence worksheetSynthetic planning case: A toy one-step forecast plan uses observations through day three to predict day four, then through day four to predict day five, and through day five to predict day six.

Filled manual planning note
Invented planning text. Adapt it to your evidence and confirmed owners.
Each outcome stays beyond its own fitting cutoff while the one-step horizon remains fixed. Keep all three origins rather than letting a later fitted rule retrospectively see earlier held-out outcomes. There are three prospective origin/target pairs. At each origin, the target day is excluded from fitting; earlier observed targets can become allowed history at a later origin. Actual features, fitting procedure and outcome timing must respect the cutoff. No native forecasting workflow is asserted.

Questions about this workflow
Can day-four observations be used at the day-four origin?
Yes once observed and allowed; they could not be used in the earlier day-three prediction of day four.
Does three-origin coverage establish future accuracy?
No. This plan defines evaluation boundaries, not a validated performance result.
Does this create tasks in the product?
No. The brief is a manual planning resource. Use the product access link to check onboarding and the workflows available in your account.
