📝 WalkthroughWalkthroughThe pull request adds an 80% line-coverage baseline, documents its warning and recovery settings, and adds tests that validate the baseline structure and alignment with repository coverage thresholds. ChangesCoverage baseline
Estimated code review effort: 2 (Simple) | ~10 minutes Merge Risk: 🟡 Moderate · up to The PR enables baseline coverage comparison, but current validation can accept commented or malformed thresholds, while the warning-drop behavior and referenced CI configuration still have unresolved correctness gaps. Merging could leave the repository exercising or validating a coverage gate different from the intended one, so owner follow-up is needed. 🚥 Pre-merge checks | ✅ 4 | ❌ 1❌ Failed checks (1 warning)

…ison path Ready's purpose is to be a fully functional repo that works with every Workflows capability while having no application use of its own. It already runs the coverage soft gate (enable-soft-gate: true, coverage-min: 80) -- but with no config/coverage-baseline.json it never exercised the BASELINE half of that pipeline: tools/coverage_trend.py reported baseline_status=absent, computed no delta, and Maint Coverage Guard had nothing to compare. So the one repo whose job is to surface fleet CI defects was silently skipping the check. That is not hypothetical -- the guard produced exactly ONE breach issue across all thirteen repos in ten months, and Ready is precisely where that silence should have been visible. Keyed `line` on purpose: coverage_trend.py and coverage_guard.py both accept `line` or `coverage` with `line` taking precedence, and exercising the precedence path is what a conformance repo is for. Set to 80 to match this repo's coverage-min and pyproject fail_under. Measured coverage is 100% of the src/my_project scaffold -- the only code Ready owns, since everything in scripts/ and tools/ is synced fleet tooling tested upstream. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>
Ready's config/coverage-baseline.json already set line: 80.0 with warn_drop and recovery_days, matching coverage-min and pyproject fail_under -- but nothing explained what those fields do or how to update the baseline when coverage intentionally changes. README.md is repo-specific (excluded from Workflows sync) and is where this belongs. Co-Authored-By: Claude Sonnet 5 <noreply@anthropic.com>
…wn design config/coverage-baseline.json's `line` key, 80.0 value, and warn_drop/recovery_days fields were set by hand with no test enforcing them -- a future edit could silently key `coverage` again (losing the precedence-path exercise) or let `line` drift from pr-00-gate.yml's coverage-min or pyproject's fail_under without anything catching it. Adds tests/test_coverage_baseline.py to assert all three agree and stay keyed `line`. Co-Authored-By: Claude Sonnet 5 <noreply@anthropic.com>

Why this belongs in Ready specifically
Ready exists to be a fully functional repo that works with every Workflows capability, while having no application use of its own. Judged against that purpose it was passing on workflows — all 33 consumer-template workflows are present — but silently failing on one pipeline.
It already runs the coverage soft gate:
But with no
config/coverage-baseline.json, it never exercised the baseline half of that pipeline.tools/coverage_trend.pyreportedbaseline_status: absent, computed no delta, and Maint Coverage Guard had nothing to compare against.So the one repo whose job is to surface fleet CI defects was quietly skipping the check.
That isn't hypothetical. The guard produced exactly one breach issue across all thirteen repos in ten months, and it turned out never to have executed to completion anywhere (see stranske/Workflows#3252). Ready is precisely where that silence should have been visible first.
