v0.12.2

Fixed

• Claude Code meta-bridge installs on the supported 2.1.x floor. Claude's plugin validator is a closed schema whose accepted marketplace keys differ by patch level; 0.12.1's root-level marketplace.json description passed on Claude 2.1.195 but failed on the floor host's 2.1.97 with Unrecognized key: "description". The marketplace manifest now keeps only the minimal root keyset confirmed on the floor (name, owner, plugins), leaving explanatory text in installer/docs comments rather than in closed-schema JSON.
• Installed meta-bridge MCP wiring no longer bakes pnpm store paths. On npm/pnpm-installed hosts, the user-scope Claude MCP entry now points at the stable entwurf-bridge bin instead of $REPO/mcp/entwurf-bridge/start.sh, whose $REPO can be a .pnpm/@junghanacs+entwurf@.../node_modules/... hash path that goes stale on version or peer changes. Development clones still pin to that clone's start.sh; both branches preserve the external Claude sender env (ENTWURF_BRIDGE_EXTERNAL_AGENT_ID=external-mcp/claude-code, ENTWURF_BRIDGE_REQUIRE_META_SENDER=1).

Added

• check-meta-manifest-schema — a CLI-version-independent meta-bridge manifest guard. The new deterministic gate pins the Claude marketplace/plugin/hooks manifests to the minimal keysets used by the meta-bridge, including the load-bearing hook event names (SessionStart, CwdChanged, UserPromptSubmit, FileChanged) and hook command keys. It also asserts meta-bridge-state.py::desired_mcp() chooses the installed-vs-clone MCP wiring without invoking a real Claude CLI. The gate is wired into pnpm check so future decorative closed-schema keys fail before release.

Verification

• pnpm check passes with the new check-meta-manifest-schema static guard included.
• ./run.sh smoke-meta-install-state passes, proving the state manager/doctor consumers still follow desired_mcp() without drift.
• Installed-location regression probe passes: running scripts/check-meta-manifest-schema.py from a synthetic node_modules/@junghanacs/entwurf package no longer self-fails.
• Claude Code 2.1.97 floor validation passed on hejdev6 after removing the root marketplace description; current Claude 2.1.195 validation also passes with warnings only.
• LIVE=1 ./run.sh release-gate /tmp/psa-release-gate-0.12.2.NLGhet passed on 2026-06-29 with MUST: PASS=17 FAIL=0 SKIP=0 and BEHAVIOR: PASS=1 FAIL=0; log /tmp/entwurf-release-gate-0.12.2-20260629T205339.log.
