V6 phrase NON-AUTHORIZABLE. Current V7 source adds isolated bwrap `--tmpfs /tmp` and skips symlinks in make_writable; real bwrap temp creation PASS; regressions RED→GREEN. Constants bind `/live-transaction-preseal-v7-sandbox-cleanup`. Strict closure: 69 tests; Ruff 32 PASS; basedpyright 0/0/0; ty PASS; no-excuse 32; LSP clean. Preserve all predecessor bytes/evidence. Freeze NEW V7 paths, NEW digest/phrase, manifest last, include all blockers/supersessions, run exact verifier. No rehearsal/live/approval use.",
