This PR successfully implements safe fetch failure diagnostics with sensitive data redaction. The implementation correctly handles HTTP responses and transport failures as verified by comprehensive tests.
Critical issues identified:
- Potential security vulnerability in redaction logic when handling special regex characters in error messages (line 39)
- Query string redaction may not fully redact URL-encoded parameter values (lines 30-33)
Additional concerns:
- Authorization header redaction pattern may not handle all edge cases (lines 17-20)
- String truncation doesn't account for multi-byte character boundaries (lines 64-67)
The core functionality works correctly, but the redaction logic should be strengthened to ensure no sensitive data leaks in edge cases before merge.

Address review findings on #174: - Redact X-Api-Key/X-Auth-Token/Proxy-Authorization and all Authorization schemes (Digest params) to end of line instead of stopping at whitespace - Redact authorization/cookie/set-cookie JSON keys and ADT XML entry attribute form (<entry key="access_token">secret</entry>) - Pass statusText through redactDiagnostic before formatting - Redact error.stack before printing (first line carries the message) - Defensive cause.message ??

Prefer parsing and reserializing JSON with sensitive keys redacted, while
retaining a text fallback for non-JSON content; add regression coverage in the
fetch tests for escaped quotes and apostrophes.

- JSON value redaction now consumes escaped quotes (\"') via

longer leaks the suffix after the escaped quote
- Convert new RegExp patterns to String.raw (addresses SonarCloud

- Add not.toContain assertions for username="u" and x=1 fixture values
- Add regression test for escaped quotes in JSON sensitive values

Inline SENSITIVE_KEY_FRAGMENT into each regex literal instead of interpolating via new RegExp(String.raw`...`). Codacy flags non-literal RegExp constructors (CWE-1333). The fragment is a hardcoded constant, not user input, so this is a lint compliance fix with no behavior change.

User description
What changed
The adt fetch command now prints safe, actionable diagnostics to stderr when a request fails:
Why
Consumers previously saw only TypeError: fetch failed, which cannot distinguish firewall, proxy, or TLS resets from an HTTP response.
Verification
Summary by cubic
Exposes safe, actionable diagnostics for failed
adt-clifetches so users can distinguish HTTP errors from transport issues without leaking secrets. Previously: a generic “TypeError: fetch failed.” Now: structured, redacted error output with bounded response excerpts and sanitized stacks.Authorizationschemes incl. Digest params,Proxy-Authorization,X-Api-Key,X-Auth-Token), cookies; sensitive JSON keys with escape‑aware value matching; ADT XML contents and<entry key="...">; query strings; statusText; error messages and stack traces.formatFetchFailure; adds tests for HTTP vs transport cases, redaction (incl. escaped‑quote JSON and Digest params), and safe truncation. Switches to regex literals to satisfy Codacy’s non‑literal‑RegExp rule (no behavior change). Successful requests are unchanged.Written for commit 5d5018b. Summary will update on new commits.
