## Implementation Complete ### What was implemented Added Cloudflare Access authentication to the HTTP client with the following features: 1. **`_get_cf_auth()` method** (client.py:155-192) - Priority chain: session cache → browser cookies → service tokens - Caches browser-extracted tokens for future requests - Returns auth method used for logging 2. **Modified `_make_request()`** (client.py:412-456) - Adds `Cookie: CF_Authorization=<token>` header when using cached/browser auth - Adds `CF-Access-Client-Id` + `CF-Access-Client-Secret` headers for service tokens - Logs auth method used in verbose mode 3. **`_handle_cf_auth_error()`** (client.py:194-234) - Clears cached session on 401/403 - Detects Cloudflare errors via CF-RAY header - Provides helpful error messages with remediation steps 4. **Verbose logging** - Shows `[auth: cache]`, `[auth: browser]`, `[auth: service token]`, or `[auth: none]` ### Test Results All 74 tests pass (22 new CF auth tests + 52 existing tests): - `TestGetCfAuth`: 5 tests for fallback chain - `TestMakeRequestWithCfAuth`: 4 tests for header injection - `TestHandleCfAuthError`: 5 tests for error handling - `TestAllHttpMethods`: 4 tests for GET/POST/PUT/DELETE - `TestVerboseLogging`: 4 tests for auth method logging ### Files Changed - `src/kafkactl/client.py` - Main implementation - `tests/test_client_cf_auth.py` - New test file (22 tests) ### Commit ``` 5d7b92b KAFKA-4: Implement Cloudflare authentication in HTTP client ``` Note: Could not push to remote (repository access issue), but changes are committed locally.

## Feature Triage Update **Status:** READY TO IMPLEMENT - All dependencies complete ### Previous Blocker Resolved KAFKA-2 (session cache) has been committed to git: ``` 9e8fcb1 KAFKA-2: Implement session cache with expiration tracking 31e22cf KAFKA-3: Add Cloudflare service token support to config 9ddaed5 KAFKA-1: Add browser cookie extraction for CF_Authorization ``` ### Implementation Summary | Component | Status | Location | |-----------|--------|----------| | Browser cookie extraction | ✅ | `src/kafkactl/auth.py` | | Session cache | ✅ | `src/kafkactl/session_cache.py` | | Config schema | ✅ | `src/kafkactl/config.py` | | Service token headers | ✅ Partial | `src/kafkactl/client.py:131-135` | | `_get_cf_auth()` method | ❌ | Needs implementation | | CF auth in `_make_request()` | ❌ | Needs modification | | Auth error handling | ❌ | Needs implementation | ### Key Implementation Points 1. Add `_get_cf_auth()` method with priority: cache → browser → service token 2. Modify `_make_request()` to add `Cookie: CF_Authorization=<token>` header 3. Add `_handle_cf_auth_error()` to clear cache and provide user guidance on 401/403 4. Reference impl available in verkurl (`verkurl/utils/sessions.py`) ### Complexity **Medium** - ~60-80 lines new code, ~150-200 lines tests ### Files to Modify - `src/kafkactl/client.py` - Main implementation - `tests/test_client_cf_auth.py` - New test file See full triage report: `/tmp/triage-KAFKA-4.md`

## Feature Triage Complete **Status:** BLOCKED - KAFKA-2 dependency not committed ### Summary This feature integrates Cloudflare Access authentication into the HTTP client with fallback chain: browser cookies → session cache → service tokens. ### Critical Finding: KAFKA-2 Not Committed The session cache (KAFKA-2) is marked as 'done' in trckr but **was never committed to git**. Only KAFKA-1 and KAFKA-3 appear in git history: ``` 31e22cf KAFKA-3: Add Cloudflare service token support to config 9ddaed5 KAFKA-1: Add browser cookie extraction for CF_Authorization ``` **KAFKA-2 must be re-implemented before KAFKA-4 can proceed.** ### What Currently Exists | Component | Status | |-----------|--------| | Browser cookie extraction | ✅ Done (KAFKA-1) | | Config schema (CF tokens) | ✅ Done (KAFKA-3) | | Service token headers | ✅ Done (in client.py) | | Session cache | ❌ NOT IN GIT | | CF auth integration | ❌ Not implemented | ### Implementation Location - `src/kafkactl/session_cache.py` - NEW (must complete KAFKA-2 first) - `src/kafkactl/client.py` - Add _get_cf_auth(), modify _make_request() - `tests/test_client_cf_auth.py` - NEW ### Complexity Medium - patterns established, good reference impl in verkurl ### Action Required 1. Re-open KAFKA-2 and implement+commit session cache 2. Then proceed with KAFKA-4 See full triage report: `/tmp/triage-KAFKA-4.md`
