[suprie]

Queued runs interrupted mid-phase currently start a fresh implementation session, while repository-local runtime YAML can differ between worktrees. This change saves run plans and execution snapshots in per-user SQLite and continues unfinished work in the retained worktree.

Changes

• Import legacy runtime YAML once from the canonical main checkout; preserve the original files.
• Share operational records across linked worktrees and check execution revisions inside a write transaction.
• Save provider session checkpoints before a final response exists. Continue unfinished phases with native resumption or recovery instructions, without requeuing completed phases.
• Add “Continue unfinished loop” controls and shared ASD-STE100 writing guidance for Claude and Codex.
• Document the migration boundary and update project memory.

Validation

Validated after integration with current main (b6f72fa, including the handoff changes):

• 766 Rust unit tests passed; 9 live-provider tests ignored.
• 34 frontend tests passed.
• Frontend production build, formatting, strict Clippy, and staged secret scan passed.
• Documentation-test harness passed with an isolated build directory.
• Recovery tests cover retained worktree edits, shared state, stale writes, provider checkpoints, and missing Codex-thread fallback before task dispatch.

Scope and follow-up

This is the first migration slice. Interactive “Start next loop” still starts a fresh conversation. Transcripts, multi-agent manifests, and delivery/handoff records retain their existing file storage. Live-provider interruption/resumption still needs a manual smoke test.

The SQLx dependency required cached transitive dependency resolution updates in Cargo.lock. Pre-existing runtime YAML edits and unrelated PRD checkbox changes are excluded.
