 **Vulnerability:** Workflow CI Security Bypass / Markdown Injection
 **Learning:** The GitHub Actions workflow `opencode-review.yml` attempted to optimize performance by doing a fast-path bash string extraction. If this succeeded, it skipped the Python JSON normalizer (`opencode_review_normalize_output.py`). This is a security flaw because the bash script does not escape `<, >, &` characters, allowing attackers to inject `-->` directly in JSON strings to break out of HTML comment sections.
 **Prevention:** Removed the fast-path check entirely. We must always enforce JSON normalization via `opencode_review_normalize_output.py` because it correctly parses the JSON payload and safely escapes all characters as `\u003c`, `\u003e` and `\u0026`.
-## 2026-06-28 - Align Sensitive Log Redaction Across Languages
-**Vulnerability:** Information Disclosure / Secret Leakage
-**Learning:** The Bash CI script (`collect_failed_check_evidence.sh`) aggressively redacted a broad range of secrets like AWS keys, Slack tokens, and generic API keys. However, the Python PR review scheduler script (`pr_review_merge_scheduler.py`) only redacted a very narrow set of standard GitHub tokens (`ghp_` and `github_pat_`). This disparity left the Python-driven command logs vulnerable to exposing other high-value secrets on command failure if they were passed via environment or arguments and inadvertently caught in error tracebacks.
-**Prevention:** We must maintain parity between cross-language redaction strategies that operate on CI environments. Replicated the extensive regular expressions for secrets (e.g., Slack, AWS, password combinations, all GitHub token prefixes) to the Python error handler.
 ## 2026-06-25 - Prevent CI Logs Security Exposure and Explicit Shell Usage
 **Vulnerability:** Information Disclosure / Command Injection
-**Learning:** `subprocess.run` defaults to `shell=False`, but linters like Bandit require explicit `shell=False` to pass security checks. Furthermore, failing GitHub CLI commands or curl requests can include full command arguments and stderr in raised errors. These strings can contain GitHub PATs, Bearer/token authorizations, API keys, or specialized GitHub token prefixes such as `gho_`, `ghu_`, `ghs_`, and `ghr_`.
-**Prevention:** Always explicitly define `shell=False` when using `subprocess.run()`. Scrub sensitive tokens from both command arguments and `stderr` before including them in exceptions or logs from CI scripts, including the `gh[pousr]_` prefix family and `github_pat_`.
-## 2026-06-30 - Prevent Security Theater in Subprocess Fixes
-**Vulnerability:** Command Injection / Incomplete Fix
-**Learning:** Fixing a `shell=True` vulnerability by replacing it with `shell=False` and wrapping the command string in `["/bin/bash", "-c", command]` is security theater. If `command` contains untrusted input, passing it to `bash -c` as a single string means it is still completely vulnerable to shell injection, while misleading linters into reporting the code as secure.
-**Prevention:** When refactoring away from `shell=True`, avoid invoking shells entirely. Use `shlex.split(command)` to safely parse the string into a list of arguments and pass that list directly to `subprocess.Popen` or `subprocess.run`, ensuring untrusted input is never evaluated by a shell.
-## 2026-06-30 - Prevent SSRF and Local File Inclusion via Unvalidated URL Schemes
-**Vulnerability:** Server-Side Request Forgery (SSRF) / Local File Inclusion
-**Learning:** Functions that fetch URLs provided via user inputs (e.g., `wait_for_url` fetching `--backend-ready-url` in CI scripts) can inadvertently read local files if they do not validate the scheme. Python's `urllib.request.urlopen` supports `file://` schemes, allowing attackers to access arbitrary file contents from the host machine or sandbox if they can control the URL parameter.
-**Prevention:** Always validate URL inputs to restrict allowed schemes. Check that URLs explicitly start with `http://` or `https://` before fetching them with standard libraries like `urllib`.
