v0.2.0

catnet v0.2.0 — Stability & English Standardisation

This release contains one breaking change.
If you use catnet --format csv export input.json,
update your scripts before upgrading. See the migration note below.

---

⚠️ Breaking Change

export --format is no longer inherited from the root command.

Previously, the global --format flag was inherited by the export
subcommand as a side effect. This was undocumented behaviour and caused
ambiguity when both flags were present.

Before (v0.1.0):

catnet --format csv export input.json      # worked by accident

After (v0.2.0):

catnet export input.json --format csv      # required form
catnet export input.json -f csv            # shorthand also works

--format is now a required local flag on export. Omitting it
produces a clear error: required flag "format" not set.

What's New

Fixed — Test Infrastructure

• Integration tests no longer share Cobra command state between cases.
  TestMain now instantiates a fresh rootCmd per test, eliminating
  order-dependent failures that could silently pass or fail depending
  on execution sequence. (Finding C6)
• os.Stdout pipe is now unconditionally restored via defer in all
  integration tests that redirect standard output. Previously, a test
  failure before w.Close() would leak the file descriptor and corrupt
  subsequent test output. (Finding C7)
• TestScanCancelledByContext has been rewritten as a subprocess test.
  The catnet binary is compiled once in TestMain and executed as a
  child process. os.Interrupt is sent only to the child PID, fully
  isolating signal delivery from the test runner process. (Finding C10)

Added — Test Coverage

• output/human.go and output/json.go now have dedicated unit tests
  using an injected io.Writer. Coverage includes: tabwriter column
  alignment, ANSI colour flag propagation, TTY detection fallback path,
  and stderr/stdout routing for all six event types. (Finding C9)

Changed — Dependencies

• catnet-core updated from development pseudo-version
  v0.1.1-0.20260606132841-09db82a7e02c to stable release v0.2.0.
  This brings the defensive timeout fix, pointer aliasing fix, and
  PortCount() method to all users of the CLI.

Changed — Repository

• All Portuguese comments, documentation strings, and user-facing
  messages have been standardised to English. No functional changes.
  Flag names, exit codes, and output format are identical to v0.1.0.
