Phase 0 closure (Path B2, post-rewrite):
addlicense sweep — adds the canonical certctl LLC copyright + BUSL-1.1
SPDX header to every production Go file. Template:
// Copyright 2026 certctl LLC. All rights reserved.
// SPDX-License-Identifier: BUSL-1.1
Coverage: 338 / 338 production Go files (cmd/ + internal/, excluding
*_test.go and **/testdata/**). Pre-sweep coverage was 22 / 338 (6.5%);
post-sweep is 338 / 338 (100%).
Normalized 22 pre-existing legacy headers (`// Copyright (c) certctl`
+ `// SPDX-License-Identifier: BSL-1.1`) and 1 file using a
`Certctl Contributors` attribution. The legacy SPDX ID `BSL-1.1`
is non-standard; the official SPDX identifier for Business Source
License 1.1 is `BUSL-1.1` (capital U). All 338 files now share the
canonical form.
Generated via:
addlicense -c "certctl LLC" -y 2026 \
-f cowork/legal/copyright-header.tpl \
-ignore '**/testdata/**' -ignore '**/*_test.go' \
cmd/ internal/
Verification:
find cmd internal -name '*.go' -not -name '*_test.go' \
-not -path '*/testdata/*' \
-exec grep -L '^// Copyright 2026 certctl LLC' {} \; | wc -l
Returns: 0
gofmt clean. Header additions are comments only, no compile impact.
