shankar0123 21aeed4f4e legal: addlicense headers + normalize legacy variants (Phase 0 RED-4)
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.

// Querier is the subset of *sql.DB and *sql.Tx that repository methods
// need. Both stdlib types satisfy it without an adapter.
//
// Repository methods that must participate in a service-layer
// transaction (audit atomicity for issuance / renewal / revocation)
// expose *WithTx variants that take a Querier; the bare methods remain
// for stand-alone use cases that do not need transactional semantics.
//
// Service code uses postgres.WithinTx to begin a tx and pass *sql.Tx
// (which satisfies Querier) into the *WithTx methods. Mock
// implementations in tests take the same Querier parameter and ignore
// it (mocks have no DB; they have in-memory state).
//
// Closes the #3 acquisition-readiness blocker from the 2026-05-01
// issuer coverage audit (Part 1.5 finding #1).

// Transactor abstracts the "begin tx, run fn, commit/rollback" lifecycle
// so service-layer code can run multi-write operations atomically without
// holding a *sql.DB directly. The postgres package provides the
// production implementation via postgres.NewTransactor; tests provide a
// mock implementation that runs fn synchronously against in-memory
// state.
//
// fn receives a Querier — either *sql.Tx (production) or a test stand-
// in. fn returns error to signal "roll back" or nil to signal "commit".
//
// This interface closes the #3 acquisition-readiness blocker from the
// 2026-05-01 issuer coverage audit: audit row + cert insert / revoke
// row + cert update must be atomic with the operation, and the
// service layer must not depend on the postgres concrete types to
// achieve that.
