v0.12.3

Changed

• Claude ACP dependency lane refreshed for Sonnet 5. The ACP runtime pins now use @agentclientprotocol/claude-agent-acp@0.54.1 with @agentclientprotocol/sdk@1.1.0, while keeping the direct @anthropic-ai/sdk@0.100.1 peer-resolution pin. The pi adapter floor is now @earendil-works/pi-* >=0.80.3 <0.81, matching the runtime catalog that exposes claude-sonnet-5.
• Curated Claude surface moves from Sonnet 4.6 to Sonnet 5. claude-sonnet-5 replaces claude-sonnet-4-6 across the ACP provider, demo/default smoke targets, pi target registry, and release docs. The Sonnet-specific 200K cap was removed; Sonnet 5 now surfaces the verified 1M context window like the Opus anchor, with a 1M ceiling guard to prevent silent future inflation.
• Release and backend docs are version-neutral where the repo shape is stable. The README now describes the durable repository shape instead of a point-in-time 0.12.x state, and the clean-host/demo/verification docs reflect the current pi floor and Sonnet 5 defaults.
• Cortex and fresh-spawn planning docs realigned to the 0.12 substrate. The ACP backend rail documentation and NEXT/ROADMAP planning notes now describe the as-built adapter seam and the mux-visible fresh-sibling lane without re-centering old v1/fat-bridge assumptions.

Fixed

• Live ACP smoke timeout cleanup no longer leaves stale timers after PASS. Raw-turn, overlay, memory-containment, and session-reuse live smokes now clear their timeout handles when the awaited operation wins, so a successful live check exits promptly instead of lingering until the old timeout expires.
• Session-reuse live smoke now preserves its success evidence. The two-turn reuse smoke no longer calls process.exit(0) on success, allowing the turn-2/PASS log and cleanup to drain naturally while the retained ACP child is still handled by the backend exit cleanup.
• Claude Code meta-bridge install state also disables workflow surfaces. enableWorkflows and workflowKeywordTriggerEnabled are now managed false alongside the existing auto-memory, compaction, prompt-suggestion, progress, and auto-mode settings.
• Unsupported ACP Codex targets are not advertised. The target registry keeps Codex on the native openai-codex provider only; entwurf/gpt-5.4 and entwurf/gpt-5.5 are removed until an ACP Codex backend exists.

Verification

• pnpm check passed on 2026-07-01 after the dependency/model/doc updates; prep log /tmp/pi-tmux-entwurf-prep-check-0123.log ended with EXIT=0.
• LIVE=1 ./run.sh smoke-acp-raw-turn-live passed with claude-sonnet-5 and exited promptly after PASS.
• LIVE=1 ./run.sh smoke-acp-provider-live passed with claude-sonnet-5 through the pi provider path.
• LIVE=1 ./run.sh smoke-acp-session-reuse-live passed with a two-turn reused ACP child; turn 2 recalled the turn-1 codeword from delta-only prompt scope.
• LIVE=1 ./run.sh release-gate /tmp/psa-release-gate-0.12.3.ZcRc8w passed on 2026-07-01 with MUST: PASS=17 FAIL=0 SKIP=0 and BEHAVIOR: PASS=1 FAIL=0; log /tmp/pi-tmux-entwurf-release-gate-0123.log.
