Feature delivery evidence

Read repository instructions and apply session-delivery-hygiene. This skill does not authorize publication, new dependencies, or unrelated changes. Use proportionate evidence; do not turn a small fix into a repository-wide audit.

1. Start and maintain the decision record

For every new feature, extend its existing design document/RFC or create docs/decisions/<feature-name>.md. Keep it versioned with the implementation and link it from the PR so the reasoning survives the session. Do not create duplicate records; non-feature fixes can use existing issue/PR rationale. Keep temporary logs and captures in task-owned artifact storage, not in source control; preserve concise findings and accessible evidence references in the record. Do not include secrets, personal data, or public vulnerability details.
