MODIFIED Requirements

Requirement: Operational and historical authority is preserved

Keyword retirement SHALL stop future discovery and SHALL permit existing unfenced pending/deferred targets attributed to retired exact queries to enter an audited, reversible cold state without deleting or rewriting historical authority.

Scenario: Dedicated source sentinels remain

• WHEN archive and gist source rotations are loaded
• THEN gharchive, gharchive-files, and gists SHALL remain as their sole configured query tokens

Scenario: Persisted rotation index remains valid

• WHEN an existing query index exceeds a shortened query list
• THEN normal modulo-based rotation SHALL select a valid configured query without a state-file edit

Scenario: Existing backlog is preserved but held

• WHEN a previously admitted unfenced target is attributed to a retired exact query and selected by reviewed policy
• THEN its queue row SHALL remain present with all attribution, retry, deduplication, scan, reservation, and coverage history preserved while its status becomes unclaimable cold

Scenario: Historical records remain unchanged

• WHEN a stale-query cold transition is applied
• THEN existing target scans, findings, credentials, keycheck results, completed queue rows, and coverage records SHALL NOT be deleted or rewritten
