Everyday-use refinement roadmap: connection, command loop, sessions, transcripts

[R055LE]

Everyday-use refinement roadmap

Why

Threadline's remaining Phase 5 exit criterion in #2 was a ten-user, two-week technical alpha. The owner has chosen to supersede that criterion with a focused everyday-use track. This does not claim the old criterion passed. Signed builds continue through invited sharing until the new flows are accepted.

Delivery order

1. Faster connection: reusable identities, opt-in saved SSH passwords, and direct connection from Home.
2. Smoother command loop: manual replies to running commands, durable completed turns, honest shell recovery, and automatic persistent/isolated routing.
3. Multiple sessions: up to three independent live SSH sessions with switching and one aggregate notification.
4. Transcript polish and acceptance: saved-history search, large-output navigation, and a combined minified, installed, and invited-tester check.

Product boundaries

• Unknown host keys still require confirmation; changed keys remain blocked.
• Saved SSH passwords require device approval per use on Android 11+. Older devices keep session-only passwords. Imported-key passphrases and privilege-prompt replies remain session-only.
• Replies to running commands are user-initiated. A masked local field cannot prevent a remote program from echoing a secret into output.
• Automatic command routing is deterministic and best effort. Mixed or risky ambiguous input asks before sending, and an accessible override remains.
• Process death or network loss never claims to resume a remote shell. Reconnect starts a fresh verified shell.
• No cloud backend, analytics, public prerelease, or permanent signing key in CI is part of this track.

Acceptance gates

• Connection: a trusted saved host with a ready identity starts connecting from one Home tap, plus device approval when using a saved password.
• Command loop: ordinary persistent state survives, isolated strict failures do not close the shell, and manual masked replies bypass local history and diagnostics.
• Sessions: three independent connections can coexist; switching never moves input or drafts between them; closing one does not close another.
• Release: relevant JVM, Android, fixture, minified, installed-update, and owner-device checks pass; invited tester feedback covers the new task paths.
