# Task: Phase-signals example

## Intent

A minimal brief that exercises the v5.1 phase_signals additive field with a
mix of effort levels and model overrides. Used by tests/validators to confirm
the validator accepts well-formed signals across the supported tier matrix.

## Goal

Validator returns valid: true. annotate.mjs strips phase_signals from the
rendered HTML body (frontmatter stays in source).

## Success Criteria

- Validator passes.
- annotate.mjs determinism: re-run produces byte-identical HTML.
