+- Hardened `coverage-gate` file input handling by validating and normalizing policy/profile paths before opening files, resolving `G304` findings in `coverage-gate/parse.go`.

 - Consolidated `run-vociferate` binary and source execution flows directly into the main `run-vociferate` action to avoid nested local-action path resolution issues on strict runners.
 - Hardened workflow module hygiene by retrying `go mod verify` after a module-cache refresh (`go clean -modcache` + `go mod download`) when runners report modified cached dependency directories.

+# coveragegate
+
+Standalone coverage-threshold enforcement tool for this repository.
+
+This tool is a quality gate. It is not part of Cue runtime orchestration.
+
+## What it does
+
+- Reads a Go coverage profile (for example `_build/coverage.out`).
+- Loads package coverage policy from JSON.
+- Discovers packages under a source root using `go list ./...`.
+- Evaluates per-package statement coverage against policy thresholds.
+- Prints a package table and returns a non-zero exit code when any package fails.
+
+## Repository integration
+
+Primary repository flow:
+
+1. `just test-coverage` runs tests in `src/` and writes `_build/coverage.out`.
+2. `scripts/check-core-coverage.sh` runs this tool from `tools/coveragegate/`.
+3. The script currently passes:
+   - `--profile $ROOT_DIR/_build/coverage.out`
+   - `--policy $ROOT_DIR/docs/coverage-thresholds.json`
+   - `--src-root $ROOT_DIR/src`
+
+## Usage
+
+From repository root:
+
+```bash
+cd tools/coveragegate
+go run . \
+  --profile ../../_build/coverage.out \
+  --policy ../../docs/coverage-thresholds.json \
+  --src-root ../../src
+```
+
+Or use the repository wrapper:
+
+```bash
+bash scripts/check-core-coverage.sh
+```
+
+## Flags
+
+- `--profile`: Path to Go coverage profile.
+- `--policy`: Path to JSON policy file.
+- `--src-root`: Directory where packages are discovered with `go list ./...`.
+
+## Exit codes
+
+- `0`: All in-scope packages meet threshold.
+- `1`: Policy/profile/load failure or one or more packages below threshold.
+- `2`: Invalid CLI arguments.
+
+## Policy model (current)
+
+The tool expects a JSON object with at least:
+
+- `minimum_statement_coverage` (number)
+- `critical_packages` (array)
+
+Each critical package may include:
+
+- `package` (string)
+- `minimum_statement_coverage` (number)
+- `include` (boolean)
+- `exclusions` (array of strings)
+
+Behavior notes:
+
+- If a package has no policy override, the global minimum is used.
+- Generated/composition files are excluded by built-in rules.
+- Packages with no statements are treated as passing.
+
+## Development
+
+Run tests:
+
+```bash
+cd tools/coveragegate
+go test ./...
+```
+
+Keep code `gofmt` and `go vet` clean.
