 ## [Unreleased]
 
+## [0.0.71] - 2026-09-13
+
+nddev-builder guidance is refreshed against each harness's current native
+extension model. Codex custom agents now cover inherited session settings and
+project scope; its hook guide includes Interrupt and the limits of asynchronous
+hooks as enforcement. Antigravity plugin and subagent guidance records the
+current manifest minimum, bundled agents, workspace isolation, inherited safety
+boundaries and validation behavior observed in CLI 1.2.2.
+
+Every builder manifest now cites all vendor pages used by its generated
+component guides, including sources beyond the base permission posture. The
+provider protocol, setup ownership and software artifact pins are unchanged.
+
+## [0.0.70] - 2026-09-13
+
+Software artifacts are refreshed from verified vendor bytes: Claude Code
+2.1.270, Codex 0.154.0, Grok Build 1.0.31, OpenCode 1.18.30, Cursor
+2026.09.10-fd3934a and Antigravity CLI 1.2.2. Pi remains at 0.85.1.
+Every published platform digest and rollback pin is transcribed from the same
+verified ledger.
+
+Lifecycle integration tests remain compatible with the pinned Rust 1.98.0
+toolchain by reading Cargo's executable path at runtime. Provider behavior,
+protocol-v3 declarations and setup ownership are unchanged.
+
 ## [0.0.69] - 2026-09-08

 **The part that does not, and says nothing when it does not**: a field absent from a column is not rejected there -- it is read past. Nothing warns, no run fails, and the component behaves differently with the same bytes. Where the field was carrying a restriction, the restriction is simply gone. Check the column before relying on one.
