API Coverage Audit

The checked-in coverage manifest records every published API operation that the CLI does not yet expose as a first-class command. The audit traces each literal client route back to a resource-client method referenced by src/commands/, so an unused HTTP helper does not count as command coverage.

Run the deterministic tests and live audit after API, client, or command changes:

python3 -m pip install --requirement scripts/requirements-audit.txt
python3 -m unittest scripts/test_audit_api_coverage.py
python3 scripts/audit_api_coverage.py \
  --write-markdown api-coverage-report.md

The audit fails for new or stale gaps, a stale checked-in snapshot, or command routes absent from the public OpenAPI catalog unless they are explicitly marked as planned or documented extras in api-coverage.toml.

A repository-owned GitHub workflow runs every Monday and refreshes the deterministic api-coverage-report.md. When coverage changes, it opens or updates one rolling PR on chore/weekly-api-parity; the PR's CI remains blocked until the command implementation or an explicitly reviewed manifest exception reconciles the drift. A GitHub issue is used only if the automation itself fails before it can create or update that PR.

The SDK regeneration workflow can open deterministic codegen PRs because its published clients are generated from OpenAPI. The CLI command surface is still hand-written, so this repository does not present an automated audit as command generation. Repository-owned generated-model PRs are tracked separately under COVAL-2079; they require the CLI's OpenAPI type-codegen migration to be completed first.

Release Automation

CLI implementation PRs retain a human merge gate. When a merged PR changes the Cargo version, the exact main CI run must pass before Release on version bump creates the matching v* tag and calls the reusable release workflow. A merge without a version bump does not release anything.

Use the checked-in helper so Cargo.toml and Cargo.lock move together:

# New first-class commands
python3 scripts/bump_version.py minor

# Backward-compatible fixes
python3 scripts/bump_version.py patch

The release workflow validates tag/version consistency, builds all five target binaries, creates or updates the GitHub release, and updates coval-ai/homebrew-tap. A manual Release on version bump dispatch safely retries the current version without creating another tag.

Repository prerequisite:

• REGEN_PR_TOKEN: a fine-grained token with Contents and Pull requests read/write access to coval-ai/cli. The organization does not allow GITHUB_TOKEN to create pull requests.
• HOMEBREW_TAP_TOKEN: a fine-grained token or GitHub App token with Contents read/write access to coval-ai/homebrew-tap. The Homebrew update is idempotent, so retrying an already-current formula succeeds without a commit.
