+**`/gsd-ship` no longer emits a 100%-missing TDD Audit noise table** — the TDD Audit PR-body section was always emitted, but the execute pipeline only writes `gate_status:` git trailers when TDD mode is active. Without TDD mode (the default), every commit was counted `missing` and the table was pure noise with no way to disable it. The section is now gated behind `workflow.tdd_mode`: when TDD mode is off, both the TDD Audit section and the aggregate `gate_status:` trailer are skipped entirely; when on, the existing behavior is preserved.

 Harden every table cell against injection, not just subjects: escape `|` as `\|` and strip `\r`/`\n` from both commit subjects and the rendered `gate_status` value. Prefer NUL (`-z` / `%x00`) record separation, and reject any record whose fields contain the `\x1f`/`\x1e` delimiters, so an adversarial commit message cannot corrupt record or field boundaries.
