- Route image generation and editing results through the unified output API
- Preserve complete results and task metadata in quiet mode
- Localize model notices and hide process information in JSON mode
- Preserve text-mode download progress behavior
- Add image output contract regression tests

- Route vocabulary command results through the unified output API
- Preserve complete JSON responses in quiet mode and existing text layouts
- Localize empty-list and undeployed vocabulary notes
- Add CLI output regression tests and isolate inherited proxy settings

- Route synthesis results and process messages through the unified output API
- Preserve complete results in quiet mode and existing text audio streams
- Require file output for JSON streaming and return structured voice lists
- Add binary, JSON, progress and CLI regression coverage

- Route speech recognition, memory, quota and security results through the output API
- Preserve complete JSON results in quiet mode and existing text layouts

- Route all monitor and log results through the invocation output API
- Keep activation progress out of JSON and quiet output
- Preserve tables, details, pagination, request order and no-wait behavior
- Fix colored hint spacing and add output and activation regression coverage

- Route usage and Token Plan results through the invocation output API
- Keep quota cards, seat tables and one-time key results intact under quiet
- Return a structured free-tier disable report and retain failure warnings
- Add isolated output-contract and quota-view regression coverage

- Route knowledge base, category, file and collection results through the output API
- Preserve complete results under quiet and move time-range notes to stderr
- Update JSON field parsing in dependent integration tests and command manuals
- Add isolated output-contract coverage for queries, mutations and import waits

- Integrate the new command families and current main behavior

Validation: isolated combined regression suite; normal repository pre-commit checks.

Preserve main's dynamic Token Plan quota windows and hasQuotaData while retaining invocation-scoped output.

Cover multi-window, missing, zero and reset-only quota data across text/JSON, quiet and verbose modes.

Validation: 8037 isolated tests passed, 290 gated skips; seven package builds.

- Omit the redundant normalization cause from text errors
- Preserve explicit causes, error codes, JSON details and verbose stacks
- Remove the obsolete auth debug wiring TODO
- Cover bilingual rendering and the actual CLI error boundary

- Reuse invocation sources for welcome and quick-start selection
- Preserve parsed flags, Profile selection and credential precedence
- Cover single config reads and bilingual help behavior

Preserve the official MCP SDK and AIGC auto routing from main.
Route auto results, progress and SDK diagnostics through invocation output.
Keep complete JSON results under quiet and preserve native download progress.
Update SDK fixtures and cover result, error and session cleanup behavior.
