Summary

The is_sensitive_key() function in src/cleveragents/shared/redaction.py has a _FALSE_POSITIVE_KEYS set with 13 entries that prevent legitimate non-sensitive keys from being incorrectly redacted. However, only token_count is tested as a non-sensitive key in the existing BDD scenarios. The other 12 false-positive keys (token_limit, token_usage, max_tokens, total_tokens, prompt_tokens, completion_tokens, token_estimate, hot_max_tokens, summary_max_tokens, auth_method, auth_type, auth_enabled) are completely untested.

Current State

In src/cleveragents/shared/redaction.py, the _FALSE_POSITIVE_KEYS set contains 13 entries:

_FALSE_POSITIVE_KEYS: set[str] = {
    "token_count",
    "token_limit",
    "token_usage",
    "max_tokens",
    "total_tokens",
    "prompt_tokens",
    "completion_tokens",
    "token_estimate",
    "hot_max_tokens",
    "summary_max_tokens",
    "auth_method",
    "auth_type",
    "auth_enabled",
}

The existing test in features/consolidated_security.feature ("Non-sensitive key names are not flagged" scenario outline) only covers token_count as a false-positive key. The other 12 entries are never exercised in any BDD scenario.

All 12 untested keys contain sensitive substrings (e.g., auth_method contains "auth", max_tokens contains "token", prompt_tokens contains "token"). Without tests, a refactor could accidentally remove these entries from _FALSE_POSITIVE_KEYS, causing is_sensitive_key() to return True for these keys and silently redacting legitimate non-sensitive data (e.g., LLM token counts, auth method names) in structured logs and CLI output.

Proposed Improvement

Extend the "Non-sensitive key names are not flagged" scenario outline in features/consolidated_security.feature to include all 12 missing false-positive keys:

Scenario Outline: Non-sensitive key names are not flagged
  When I check if "<key>" is a sensitive key
  Then the sensitivity check should be false

  Examples:
    | key                |
    | username           |
    | email              |
    | name               |
    | description        |
    | project_id         |
    | token_count        |
    | token_limit        |
    | token_usage        |
    | max_tokens         |
    | total_tokens       |
    | prompt_tokens      |
    | completion_tokens  |
    | token_estimate     |
    | hot_max_tokens     |
    | summary_max_tokens |
    | auth_method        |
    | auth_type          |
    | auth_enabled       |

This ensures that any future refactor that accidentally removes a false-positive key will be caught immediately by the test suite.

Expected Impact

Adds 12 new scenario outline rows to an existing test, covering the _FALSE_POSITIVE_KEYS branch in is_sensitive_key() for all 13 entries. This closes a security-critical coverage gap in the redaction utility used throughout CLI output, structlog processors, and error detail formatting.

## Summary The `is_sensitive_key()` function in `src/cleveragents/shared/redaction.py` has a `_FALSE_POSITIVE_KEYS` set with 13 entries that prevent legitimate non-sensitive keys from being incorrectly redacted. However, only `token_count` is tested as a non-sensitive key in the existing BDD scenarios.

Issue: [AUTO-INF-2] Coverage gap: shared/redaction.py is_sensitive_key() missing tests for 12 of 13 _FALSE_POSITIVE_KEYS entries
Type: Task (Test Coverage / Security)
Priority: Medium
MoSCoW: Should Have

Rationale

The _FALSE_POSITIVE_KEYS set prevents legitimate non-sensitive keys (token counts, auth method names) from being incorrectly redacted in logs and CLI output. Only 1 of 13 entries is tested. A refactor that accidentally removes entries would silently redact valid data — a security-adjacent correctness issue. The fix is minimal: extend an existing scenario outline with 12 additional rows.

Marking as Should Have — the redaction utility is used throughout the system and its correctness is security-relevant. Closing this gap is important but not blocking.
