Status: COMPLETE

Commit

• Hash: 5f02db8
• Message: style(frozen-string-literal): add pragma to all Ruby files
• Files changed: 113 files, 223 insertions

Tasks Completed

Task 1: Add frozen_string_literal to app/ and lib/ source files

• Added pragma to all 29 app/ and lib/ .rb files
• No shebang lines encountered in any files

Task 2: Add frozen_string_literal to config and migration files

• Added pragma to config/routes.rb and 4 migration files

Task 3: Add frozen_string_literal to test files (excluding test/dummy and test/tmp)

• Added pragma to all 43 test .rb files
• test/test_helper.rb had no shebang, straightforward prepend

Task 4: Add frozen_string_literal to test/dummy files

• Added pragma to all 22 dummy app .rb files

Task 5: Validate full codebase compliance and run tests

• git ls-files -- '*.rb' | ... | grep -cv 'frozen_string_literal: true' returns 0
• bin/rubocop --only Style/FrozenStringLiteralComment exits 0 (341 files, no offenses)
• bin/rails test passes: 473 runs, 1927 assertions, 0 failures, 0 errors

Deviations

DEVN-02: Non-.rb Ruby files also needed the pragma (14 additional files)

The plan scoped only .rb files, but the success criterion requires bin/rubocop --only Style/FrozenStringLiteralComment to pass. RuboCop also inspects non-.rb Ruby files: Gemfile, Rakefile, source_monitor.gemspec, 3 .rake files, test/dummy/Gemfile, test/dummy/Rakefile, 5 test/dummy/bin/* scripts, and test/dummy/config.ru. All 14 were given the pragma.

DEVN-02: test/tmp/ excluded from RuboCop

RuboCop was scanning 179 files under test/tmp/ (untracked generated host app templates) which all lacked the pragma. Since these are not git-tracked and are generated artifacts, added test/tmp/**/* to .rubocop.yml AllCops Exclude list rather than modifying generated files.

DEVN-01: Shebang handling for bin scripts

Five test/dummy/bin/* files had shebang lines. The pragma was correctly inserted after the shebang on line 2. Two files (bin/dev, bin/jobs) had a blank line between the shebang and the first require, which would have created a double blank line; these were cleaned up to have a single blank line separator.

Decisions

1. Included non-.rb Ruby files -- To satisfy the RuboCop success criterion, all Ruby-like files RuboCop inspects needed the pragma, not just .rb files.
2. Excluded test/tmp/ from RuboCop -- These are generated Rails app templates that are not git-tracked and should not be linted. This is a minimal .rubocop.yml change.
3. Did not modify test/lib/tmp/install_generator/config/routes.rb -- This file is not git-tracked (despite the path existing on disk from a previous test run), so it was left as-is.

Success Criteria

• Every git-tracked .rb file has # frozen_string_literal: true (REQ-13)
• RuboCop Style/FrozenStringLiteralComment cop passes with zero offenses
• No test regressions introduced (473 tests, 0 failures)
