# Implementation Notes

**Session ID**: `phase15-session01-scheduler-config-contract` **Date**: 2026-05-31

## Summary

Implemented the scheduler config contract for Phase 15 so local scheduler settings can select only reviewed jobs and cadence values, degrade safely when config is missing or invalid, and keep status output sanitized.

## Changes

* Added a sanitized private scheduler config template under `data/`.
* Added scheduler config parsing and validation helpers in `scripts/lib/scheduler/config.ts`.
* Extended scheduler status projection types and operator-status formatting to include local config state, cadence source, and timer intent.
* Added focused config and status coverage for missing, valid, invalid, and redacted config states.
* Updated scheduler documentation and environment guidance for the private config file boundary.

## Verification

* `bun run test`
* `bun run typecheck:scripts`
* `git diff --check`

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://ai-os-and-trend-finder.gitbook.io/ai-os-and-trend-finder-docs/.spec_system/archive/sessions/phase15-session01-scheduler-config-contract/implementation-notes.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
