What

Two changes to the detect -> adopt ("port") flow, plus fixes surfaced by review.

Interactive port (open the provider's own CLI)

Porting a detected session used to only run the target provider headless as a hidden child of the daemon, so nothing visibly happened except events in the dashboard. Adopt can now instead open the provider's own CLI in a terminal — in the adopted project directory, under the chosen account's config dir, seeded with a prompt that reads the full brief — then step back and let the developer drive it.

• Desktop drawer: the old "Start running it immediately" checkbox is now a mode toggle, Open in (default) vs Run in background (the previous headless path).
• New relay detect --open flag for the same from the CLI.
• POST /api/detect/adopt gains an interactive field.

Richer handoff context

The transcript reader already read every turn and kept only the first/last prompt. The brief now also carries a redacted, verbatim tail of the last 16 user/assistant turns, rendered as a "Recent conversation" section, so a port moves real recent context rather than a one-line summary. Every turn passes through the redactor before it can cross the boundary.

Fixes (from an adversarial review of the above)

• Desktop handOffSession now surfaces daemon body-level adopt errors instead of reporting false success and dismissing the panel.
• Interactive launch re-applies the persisted active account after a config reload, so it never opens the wrong account's config dir.
• POSIX env values and command args are shell-quoted (a config dir with a space, e.g. the canonical macOS path, no longer breaks the launch).
• truncate is rune-safe, so a carried turn is never split mid-character.

Tests

• New recent_turns_test.go (turn capture, window, rune-safe truncate) and an opt-in launch_smoke_test.go that spawns a real terminal via the production launcher and asserts cwd + env crossed to the child.
• Full suite: go build, go vet, gofmt, 151 Go tests, npm run typecheck, and electron-vite build all pass.

Scope

Electron desktop (packages/desktop) only; the legacy Rust egui UI is intentionally not mirrored.
