# bin/filing-plan: output path A — the marker-based idempotency contract
# (FR-6.3), template rendering (FR-6.1), and repo-less degradation (FR-6.4).
#
# The load-bearing case is "run 1 files, run 2 comments". It is proved here the
# only way that means anything: run 1's ACTUAL rendered body is fed back as the
# tracker's state for run 2. Nothing is asserted about the marker by hand.
#
# tests/fixtures/gitea-issues.json is copied verbatim from real Gitea API
# responses (probe issue kotkan/claude-plugin-inference-arbitrage#9, since
# closed), so the shape this parses is the shape the API returns.
