Subject: [PATCH 01/29] fix(cliproxy): return null for unknown quota, add
 verbose diagnostics

- Change calculateAverageQuota() to return null instead of 100 when no model data
- Update callers to use null coalescing (?? 0) for health check thresholds
- Display "N/A (fetch unavailable)" for null quota values
- Add --verbose flag to quota-related functions for troubleshooting
- Add debug logging: token refresh status, API response, errors

Subject: [PATCH 04/29] fix(deps): add express-rate-limit to production
 dependencies

express-rate-limit was imported in auth-middleware.ts but only the
@types/express-rate-limit package was declared in devDependencies.
This caused "Cannot find module 'express-rate-limit'" error when
running `ccs config` after installing v7.20.0 globally.

Closes #333

Subject: [PATCH 06/29] fix(ci): expand ai-review allowedTools to prevent token
 waste

- Add more allowed bash patterns: gh issue view, gh api, git commands
- Add base tools: Edit, LS for better flexibility
- Update prompt to write pr_review.md in working dir (not /tmp/)
- Add step to Read before Write to avoid security block
- Add explicit rules about avoiding shell operators (||, &&, <<)
- Allow rm pr_review.md for cleanup

Previous run had 9 tool rejections wasting ~5000 tokens due to:
- gh issue view not allowed (only gh pr view was)
- /tmp/ outside working directory
- Write without Read blocked
- Complex shell operators blocked

             ## IMPORTANT: Posting the Review
             After completing your analysis, post the review as a PR comment.
 
-            REQUIRED METHOD (use Write tool + --body-file):
-            1. Write your review to /tmp/pr_review.md using the Write tool
-            2. Post with: gh pr comment ${{ github.event.pull_request.number || github.event.issue.number || github.event.inputs.pr_number }} --body-file /tmp/pr_review.md
+            STEP 1: First, use the Read tool to check if pr_review.md exists (it may not exist yet, that's OK)
+            STEP 2: Use the Write tool to write your review to pr_review.md in the current working directory
+            STEP 3: Post with: gh pr comment ${{ github.event.pull_request.number || github.event.issue.number || github.event.inputs.pr_number }} --body-file pr_review.md
 
-            DO NOT use inline --body with multiline content - it will fail pattern matching.
+            IMPORTANT RULES:
+            - Write to pr_review.md (in working directory), NOT /tmp/pr_review.md
+            - Do NOT use shell operators like || or && in bash commands
+            - Do NOT use heredoc (<<) syntax in bash commands
+            - Use simple, single-purpose bash commands only

Subject: [PATCH 09/29] feat(dashboard): implement full parity UX improvements

- Remove 'agy' hardcode from quota hook (multi-provider support)
- Add quota N/A badge with AlertCircle icon for fetch failures
- Add new 'backups' tab to Settings page with Archive icon
- Create BackupsSection component with list/restore UI
- Add persist backend routes (GET /api/persist/backups, POST /api/persist/restore)
- Add debug mode toggle in Settings proxy section (localStorage persisted)

Closes documentation gap for persist command dashboard parity.

Subject: [PATCH 10/29] fix(dashboard): resolve edge cases in backup restore
 and settings UI

Backend:
- Add atomic restore with mutex to prevent concurrent corruption
- Implement rollback on failure for backup restore
- Add symlink security validation

Frontend:
- Add 'backups' tab to URL validation in settings hook
- Add error boundary for lazy-loaded settings sections
- Clamp progress bar values to prevent visual bugs
- Add AbortController cleanup to prevent memory leaks
- Fix misleading debug mode description and add actual console logging

Subject: [PATCH 11/29] fix(cliproxy): move token files when pausing/resuming
 accounts

Pausing an account now physically moves the token file to auth/paused/
subdirectory, preventing CLIProxyAPI from discovering and using it.
Resume moves the file back to auth/ directory.

Changes:
- Add getPausedDir() helper for paused tokens location
- Update pauseAccount() to move token to paused/ subdir
- Update resumeAccount() to move token back to auth/
- Update syncRegistryWithTokenFiles() to check both directories
- Update removeAccount() to clean up from both directories
- Update getAccountTokenPath() to return correct path based on state

Fixes #337

Subject: [PATCH 12/29] fix(dashboard): resolve 6 critical security and UX edge
 cases

- TOCTOU symlink attack: use file descriptor for atomic read in persist-routes
- Non-atomic mutex: add RestoreMutex class with Promise queue pattern
- Restore confirmation: add AlertDialog before destructive backup restore
- Sensitive data exposure: sanitize auth_token/management_key in debug console
- Chunk retry: add lazyWithRetry wrapper with exponential backoff (3 retries)
- URL tab case sensitivity: normalize tab param with toLowerCase()

Subject: [PATCH 17/29] fix(persist): add rate limiting, tests, and code
 quality improvements

- Add express-rate-limit to restore endpoint (5 req/min)
- Add JSDoc documentation to RestoreMutex class
- Extract magic numbers to named constants in BackupsSection
- Add unit tests for persist-routes.ts (23 tests)
- Add unit tests for BackupsSection component (28 tests)

Addresses PR #339 code review feedback.

Subject: [PATCH 20/29] feat(dashboard): add project_id display for Antigravity
 accounts

Display GCP project_id for Antigravity (agy) accounts in the Dashboard:

- Add projectId field to AccountInfo interface (account-manager.ts)
- Read project_id from auth files when discovering/registering accounts
- Pass projectId through token-manager when registering new accounts
- Add projectId to OAuthAccount type (api-client.ts)
- Add projectId to AccountRow type (auth-monitor/types.ts)
- Display project_id in account-item.tsx with FolderCode icon
- Show N/A warning with amber tooltip if project_id is missing
  suggesting user remove and re-add account to fetch it

Note: project_id is read-only and respects privacy mode blur.

Subject: [PATCH 21/29] fix(dashboard): update projectId for existing accounts
 during discovery

Previously, discoverExistingAccounts skipped existing token files
entirely, so accounts created before the projectId feature never
got their projectId populated from auth files.

Now when a token file is already registered, we still check if
projectId needs to be updated for agy accounts.

Subject: [PATCH 23/29] fix(cliproxy): add try-catch for file operations in
 pause/resume

Address PR review feedback:
- Wrap fs.renameSync() in try-catch for pauseAccount/resumeAccount
- Wrap fs.mkdirSync() in try-catch for paused directory creation
- Add idempotent checks (skip if already paused/active)
- Rely on syncRegistryWithTokenFiles() for recovery on failure

Follows same error handling pattern as removeAccount().

Subject: [PATCH 26/29] fix(cliproxy): use sibling auth-paused/ dir to prevent
 token refresh loops

CLIProxyAPI's watcher uses filepath.Walk() which recursively scans
all subdirectories of auth/. Moving paused tokens to auth/paused/
subdirectory didn't hide them from CLIProxyAPI, causing token refresh
loops where paused tokens were immediately recreated.

Solution: Use auth-paused/ as a sibling directory instead of auth/paused/
subdirectory. This places paused tokens completely outside CLIProxyAPI's
scan path, preventing token discovery and refresh.

Path change:
- Before: ~/.ccs/cliproxy/auth/paused/
- After:  ~/.ccs/cliproxy/auth-paused/

Subject: [PATCH 27/29] fix(cliproxy): show clear message for paused accounts
 in Live Monitor

- Check isAccountPaused() before readAuthData() in fetchAccountQuota()
- Return "Account is paused" instead of confusing "Auth file not found"
- Improves UX by explaining why quota fetch fails for paused accounts
