Read the code carefully

# Dockerfile (recap of the 5 layers):
#   1: FROM python:3.13-slim AS builder
#   2: WORKDIR /app
#   3: COPY pyproject.toml uv.lock ./
#   4: RUN --mount=type=cache,... pip install uv && uv sync --frozen --no-dev
#   5: COPY src/ ./src/
#
# Commit under test: only `src/handlers.py` changed.
# Prior CI build populated the layer cache one commit ago.
#
# For each layer 1..5, decide 'CACHED' or 'REBUILT' in order, as a Python
# list of strings.
#
# What does the predicted list look like? Type your prediction.
