commit 4f360e0f089890af942db99fa2cbf6ea5744f7d7
Author: Mingyu Chen (Rayner) <[email protected]>
AuthorDate: Wed Oct 14 20:46:14 2026 +0800

    fix(i18n): remove T08 token budgets and simulate draft PR flow (#4269)
    
    ## Summary
    
    - Remove T08's estimated and accumulated Codex token budgets. The
    workflow still limits successful candidates per run, document size,
    chunk size, and call duration, and records actual token usage. The
    separate T07 manual translation tool is unchanged.
    - Make one-page `validate` fail when no candidate is produced, and
    record a model call when it used tokens even if its candidate failed
    validation.
    - Normalize extra blank lines at the end of generated documents so the
    draft PR can pass `git diff --check`.
    - Add a local end-to-end simulator that runs the real selection,
    generation, translation checks, Git commit, and publish scripts against
    a local bare remote. Codex and GitHub CLI are mocked; it does not call a
    real model or create a hosted PR.
    
    ## Validation
    
    - `node --test scripts/i18n/__tests__/*.test.cjs`: 76 passed.
    - `git diff --check upstream-apache/master...HEAD`: passed.
    - Local simulator selected
    `docs/admin-manual/system-tables/information_schema/engines.md`. An
    invalid model unit made `validate` exit 1. A valid mock result reporting
    100,000 tokens produced one candidate; `check-translations.cjs` passed,
    the local remote received a draft branch containing only the Japanese
    page and state file, and the GitHub mock recorded a draft PR.
    
    ## Rollout
    
    The repository's ongoing auto-generation variables remain unset. The
    local simulation proves script integration only; OSS Codex
    authorization, real Japanese output, PAT publishing, and the resulting
    GitHub checks still need a one-page Actions validation before enabling
    ongoing generation.
