v0.13.109: v0.13.109

@newsroom.writer: new article, "Legal on demand for startups": legal services that scale with agent teams doing the reading and lawyers signing, priced per task or monthly, for founders, investors and the deal between them, with everything signed. With it, a made-up demonstration in three vaults built by this site's agents from one shared set of facts: Tallowmere Counsel's founder desk (x6kjwxds), investor desk (jgp3oyrm) and deal room (ghafqmwo), each also served as a static copy under demos/vaults/tallowmere-counsel/vault-app/. Every party has a real ECDSA P-256 key pair; the apps verify 80, 86 and 82 signatures in the browser, with tamper controls, a five-level hashed agreement, diffs, signed understandings, a blocked draft, a signing ceremony, a signed message log, scripted playback and signed receipts. Public read keys in admin/content/vaults/tallowmere-*.json; private signing keys and vault keys are not in the repository. Two figures, six screenshots, summaries and a graph.
