v3.1.2

Added

• Session-start lean lifecycle — rai session open composite call replaces the manual check sequence; ensure_session_lifecycle auto-upgrade restored; orientation ledger wired to session start.
• rai scm pre-review — pre-submission SCM review command that validates branch state before MR creation.
• Truthful execution — agent execution correctness improvements; false-positive execution claims eliminated.
• Gate skip signal quality — gate skip events now carry structured skip-reason signals; coverage gaps in skip-acceptance path closed.
• Portfolio freshness detector — rai session open evaluates freshness of all portfolio cartridges at startup, not just the primary one.

Fixed

• MCP envelope status propagation — MCP tool responses defer to payload status field instead of unconditionally reporting success.
• Session worktree resolved by newest lease — cwd-binding lease read routes through SqliteLeaseStore ordering by newest heartbeat; stale leases no longer shadow the active worktree.
• rai scm merge-mr no SCM default — falls back correctly when no SCM adapter is configured.
• Story-close merges itself — self-merge guard prevents a story branch from being merged into itself when branch names collide.
• find_epic_scope_file wrong epic — scopes file lookup to the correct epic directory instead of the first match.
• Fanout snapshot frozen — pipeline fanout no longer uses a stale snapshot after force_refetch; scope re-parsed on advance.
• MCP is_error false positive — is_error field in MCP envelope no longer triggers false-positive error detection on successful tool responses.
• Jira transition fallback state name — transition by state name falls back to case-insensitive match when exact match fails.
• Artifact emit MCP-only — raise_artifact_emit now correctly routes through MCP tool path; CLI fallback removed.
• Ledger stale on retry — ledger entries are refreshed on pipeline retry; stale cost data no longer accumulates.
• foreach-child-skill-loss — foreach phase no longer loses child skill reference after the first iteration.
• Graph semantic search degraded — embedding index rebuilt correctly after graph prune; semantic search restored.
• Graph depth-expand crash — --depth N expansion no longer panics on nodes with missing edge targets.
• Backlog bug nodes missing fields — bug-type nodes now include all required fields in the graph index.
• Graph build orphan nodes — orphan nodes pruned correctly on incremental rai graph build.
• Fleet dispatch tier resolution — fleet subagent dispatch resolves the correct tier from manifest instead of defaulting to community.
• ADR SCM status hygiene — rai scm status no longer writes ADR entries for non-SCM operations.
• Kimi model routing — Kimi runtime routes to the correct model endpoint; provider map lookup fixed.
• Governance trail CI — regression tests added for governance-trail gate path.
• Merge signal surface — rai session open surfaces pending merge signals in the drift check output.
• Squash-abort restore corruption — squash-abort no longer corrupts the working tree when restore fails mid-operation.
• Gate catalog regenerated — gate catalog refreshed; stale gate violations resolved.
• 10 additional bugfixes and reliability improvements.
