refactor(cliproxyapi): remove gitignored dotfiles auth sync logic

[shunkakinoki]

Summary

• Removed defunct dotfiles recovery/sync logic from start.sh and backup-auth.sh
• Simplified codebase by removing 48 lines of dead code
• objectstore/auths is gitignored, making git-based recovery impossible

Background

PR #472 added bidirectional R2 sync to fix "key does not exist" errors. However, it also included dotfiles recovery logic that attempts to sync auth files to/from ~/dotfiles/objectstore/auths/.

This directory is gitignored, so the recovery mechanism cannot work:

• Files in objectstore/auths won't persist in git
• Fresh clones won't have these files
• The sync is redundant since R2 backup is the source of truth

Changes

• start.sh: Removed macOS-specific dotfiles merge logic (lines 52-72)
• backup-auth.sh: Removed dotfiles recovery and sync-back logic
• Result: Cleaner, simpler code that relies solely on R2 for backup/recovery

Why This is Safe

1. R2 backup already serves as the source of truth (pulled in STEP 1)
2. start.sh now syncs local -> R2 after pulling (added in fix(cliproxyapi): sync recovered auth files to R2 on startup #472)
3. Removing gitignored directory sync has no functional impact

Summary by cubic

Removed dotfiles-based auth recovery/sync from cliproxyapi scripts and now rely solely on R2 for backup and restore. This removes dead code and avoids a non-working path since objectstore/auths is gitignored.

• Refactors
  • start.sh: removed macOS dotfiles merge; still pulls from R2 and syncs local -> R2.
  • backup-auth.sh: removed dotfiles recovery and sync-back; kept ccs auth dir sync.
  • Reason: dotfiles/objectstore/auths is gitignored, so git recovery cannot persist.

📝 Walkthrough

Summary by CodeRabbit

• Refactor
  • Simplified authentication backup scripts by removing platform-specific conditional recovery logic.
  • Streamlined authentication file synchronization flow in backup and sync operations for improved consistency across environments.

Walkthrough

The PR removes macOS-specific dotfiles-based auth file recovery logic from both backup-auth.sh and start.sh. The scripts no longer attempt to merge missing auth files from a dotfiles repository or back-sync recovered files. Instead, start.sh unconditionally syncs local auth files to R2 after pulling.

Changes

Cohort / File(s)	Summary
Removal of dotfiles-based auth recovery home-manager/services/cliproxyapi/scripts/backup-auth.sh, home-manager/services/cliproxyapi/scripts/start.sh	Removed macOS-only rsync-based merge of missing auth files from DOTFILES_AUTH_DIR in both scripts. Removed variable declarations and back-sync logic. In start.sh, replaced conditional restoration with unconditional push of local auth files to R2 after pulling.

Poem

🐰 The dotfiles fade like morning dew,
No macOS merge, no back-sync too,
Now auth files flow, direct and true,
To R2 they go—fresh and new! ✨

🔇 Additional comments (3)

home-manager/services/cliproxyapi/scripts/backup-auth.sh (1)

1-70: LGTM! Clean refactoring that simplifies the backup flow.

The removal of dotfiles-based sync logic is well-executed. The script now has a clearer flow: pull from R2, merge from CCS, then push back to both. The error handling with || true and progress messages make the script resilient and observable.

home-manager/services/cliproxyapi/scripts/start.sh (2)

52-73: LGTM! Unconditional sync prevents auth file inconsistencies.

The replacement of conditional dotfiles recovery with unconditional bidirectional sync is a solid improvement. The critical comment on line 52 clearly explains the rationale: ensuring local files always get uploaded to R2 prevents "key does not exist" errors. The redundant sync to both main and backup locations adds resilience.

---

1-151: Well-structured script with clear separation of concerns.

The script follows shell best practices: proper error handling with set -euo pipefail, defensive programming with ${VAR:-} patterns, and clear comments explaining critical sections. The refactoring successfully removes the dotfiles dependency while maintaining robust auth file synchronization.

Summary of Changes

Hello @shunkakinoki, I'm Gemini Code Assist¹! I'm currently reviewing this pull request and will post my feedback shortly. In the meantime, here's a summary to help you and other reviewers quickly get up to speed!

This pull request refactors the cliproxyapi authentication synchronization scripts by removing obsolete and non-functional dotfiles recovery logic. The changes streamline the codebase, eliminate dead code that attempted to manage gitignored authentication files, and solidify R2 as the sole, reliable source for authentication backup and recovery. This simplifies maintenance and improves the robustness of the authentication system.

Highlights

• Code Simplification: Removed approximately 48 lines of defunct dotfiles recovery/sync logic from start.sh and backup-auth.sh, simplifying the codebase.
• Auth Sync Logic Refinement: Eliminated ineffective logic that attempted to sync authentication files to/from a gitignored ~/dotfiles/objectstore/auths/ directory, which could not persist in Git.
• Centralized Backup: Consolidated the authentication backup and recovery mechanism to exclusively use R2, establishing it as the single source of truth.
• Improved Reliability: Ensured the authentication system no longer relies on a non-functional git-based recovery method for gitignored files, enhancing robustness and preventing potential issues.

Code Review

This pull request correctly removes the defunct dotfiles synchronization logic from backup-auth.sh and start.sh. The changes simplify the codebase by removing dead code, and the in-script comments have been updated accordingly. However, a significant piece of documentation, home-manager/services/cliproxyapi/README.md, has not been updated. It still describes the old architecture, which could mislead future developers. I've left a specific comment highlighting the need to update the documentation to reflect these changes.

I am having trouble creating individual review comments. Click here to see my feedback.

home-manager/services/cliproxyapi/scripts/start.sh (52-72)

While removing this dotfiles sync logic is the correct approach as it's defunct, the corresponding documentation in home-manager/services/cliproxyapi/README.md has not been updated. The README still extensively describes the dotfiles backup and recovery mechanism that is being removed here. To prevent confusion for future maintainers, please update the README to reflect that R2 is now the sole source of truth for auth file backups.
