Sub-ticket of MARS-373 Solo-agent push-gate lints (WARN-tier): archive-context PRESENCE (flag INSERT/UPDATE/DELETE on an audited table in src/ with no setArchiveContext in the same fn - the real blind spot; today's lint only validates the reason string IF setArchiveContext exists) + soft-delete-filter (flag FROM/JOIN on a soft-deletable table without deletedAt IS NULL / active-view). Both are grep/AST heuristics = high false-positive -> ship WARN-tier with curated audited-table + soft-delete-table maps + allowlist-comment escape; hard-fail only once maps curated. isUuid-guard presence deliberately NOT a static lint (too many query shapes, fragile) - left to auditsolo negative-assertion.
