`[2026-07-12]` **bifrost 1.1.1 adopted (v0.20.10, pushed) — the library-level fix for the frozen-v0.6 handshake leak.** 1.1.0's `describe_store` leaked the v0.7-additive `sortable_chunk_fields` into a v0.6-negotiated StoreCapabilities → a strict v0.6 client rejects our `:8392` handshake; 1.1.1 gates additive fields on the negotiated wire (ADR-0008). Zero-code patch repin (provider extra 1.1.0→1.1.1 + uv lock), 631 green (clean env — the 2 `test_cli` failures were an env leak from `source env.sh` exporting `RATATOSKR_ADMIN_API_KEY`), committed `62a16d2`, provider restarted on 1.1.1 (PID 3242269). Not exercisable by our v0.7 WT peer (the v0.6 fix needs a v0.6 client), but the running server is now v0.6-clean. Reference-impl adopt-canonical (bifrost-dev flagged). Also: `contract-drift-check-v1` canonical single-pin-synced (`7bca76e`, pushed; `canonical_sync.py` has no single-pin flag so did it by hand — the 2 `tolerate_drift` worldtree prose pins are deliberately held STALE for the R34/R35 eval diff-review).
