# Release a configuration change with code dependencies

Illustrative planning brief; no automatic product import.

Illustrative planning case: A new timeout setting is read only by the new binary, but configuration would change before that binary arrives.

## Decision

Treat dependent configuration and code as a sequenced release.

## Owned work

- Identify setting consumers
  - Owner role: Release investigator
  - Acceptance evidence: Old and new binaries state how they parse the setting.
- Choose compatible first step
  - Owner role: Migration engineer
  - Acceptance evidence: The configuration remains accepted during mixed-version operation.
- Review observed activation
  - Owner role: Release reviewer
  - Acceptance evidence: New behavior begins only after matching code is present.

## Workflow

1. Record how old and new binaries parse the proposed timeout setting.
2. Choose a sequence that remains valid while both versions run, with the activation condition and reversal limits written down.
3. Confirm matching code is present before treating the new setting as active; inspect observed behavior rather than only a configuration edit.

## Judgment

Do not equate configured values with observed runtime behavior.


## Filled illustrative release coordination record

In the synthetic rollout, version 2 ignores retry_window while version 3 reads it. The setting is staged without claiming activation, then version 3 deployment is verified. The release report distinguishes configuration presence from behavior in effect. If the old binary rejects unknown keys, staging must wait or use a separately supported configuration path.
Decision: Treat dependent configuration and code as a sequenced release.
Review boundary: Do not equate configured values with observed runtime behavior.
This example uses synthetic conditions. Replace its observations with project evidence and record any changed assumptions before adopting the plan.


## Workflow questions

### Does saving configuration activate the behavior?

Only in code that reads it; confirm the consuming version and effective runtime value.

### What if old code rejects new keys?

Change the sequence or use an accepted compatibility mechanism before mixed-version rollout.

## Product connection

Use the manual work brief to discuss task ownership, review evidence and next actions in TeamBoost. Release execution remains a separate project workflow; the download performs no deployment or import.

Confirm account availability before adopting this manual outline.
