2026-01-31 - M4: Sharing UX Polish - All Stories Complete

Summary

Verified that all M4 (Sharing UX Polish) features were already implemented in the codebase. The milestone focused on making normal controls work during sharing, blocking deletion of shared sessions, and removing legacy sharing key handlers.

Verification Results

Story 1: Remove restrictive sharing key handler

✅ No sharing_state.is_active() check blocking normal controls
✅ Tests verify: navigation (j/k), view (Enter), copy path (c), open folder (o), refresh (r), help (?), search (/) all work while sharing
Tests: test_sharing_navigation_still_works, test_sharing_view_session_works, test_sharing_help_works, test_sharing_search_works

Story 2: Block deleting shared sessions with message

✅ is_session_shared() helper exists in ShareManager (sharing.rs:221)
✅ Delete handler checks if session is shared (app.rs:459-471)
✅ Shows "Cannot delete: session is being shared" message
Tests: test_handle_key_d_blocked_when_session_is_shared, test_handle_key_d_allowed_when_different_session_is_shared

Story 3: Escape no longer kills shares

✅ Esc in main view clears search or quits (does not stop shares)
✅ Shares only stopped via Shares Panel (Shift+S → d to stop individual share)
✅ Shares panel Esc closes panel without stopping shares
Tests: test_sharing_esc_does_not_stop_sharing, test_shares_panel_esc_closes

Story 4: Clean up legacy sharing state

✅ handle_sharing_key() function removed from codebase
✅ No dead code warnings from clippy
✅ All 600 tests pass

2026-01-30 - M2 Story 1: Session scanner trait and Claude implementation

Summary

Implemented the session scanner abstraction for discovering sessions without full parsing. This is the first story of Milestone 2 (TUI Browser).

Changes

Created src/scanner/mod.rs:

- SessionScanner trait with scan_directory() and default_roots() methods
- ScanError enum for directory/file/metadata errors
- Builder pattern for SessionMeta with with_message_count() and with_first_prompt_preview()
Created src/scanner/claude.rs:
- ClaudeScanner struct implementing SessionScanner trait
- scan_directory() scans ~/.claude/projects/ for JSONL files
- scan_session_file() extracts metadata quickly without full parsing:
  - Reads first user prompt (truncated to ~100 chars)
  - Counts user + assistant messages
  - Gets session ID from filename
  - Uses file mtime for updated_at
- Filters out meta messages, command messages, and tool results
- truncate_prompt() helper truncates at word boundaries
- default_roots() returns ~/.claude/projects/
Updated src/lib.rs:
- Added pub mod scanner; to export the scanner module

2026-01-29 - Story 10: Tailscale serve implementation

Summary

Implemented the TailscaleTunnel provider with full spawn() functionality that creates Tailscale serve tunnels for sharing within a tailnet.

Changes

Updated src/tunnel/tailscale.rs:
- Implemented is_logged_in() method that checks tailscale status --json for BackendState: "Running"
- Implemented parse_logged_in_status() to parse JSON status and verify connection state
- Updated is_available() to check both binary existence AND logged-in status
- Implemented get_hostname() to retrieve the machine's tailscale DNS name
- Implemented parse_hostname_from_status() to extract Self.DNSName from status JSON
- Implemented construct_serve_url() to build HTTPS URL from hostname
- Implemented full spawn() method:
  - Verifies tailscale binary exists and user is logged in
  - Retrieves machine hostname from tailscale status --json
  - Spawns tailscale serve --bg=false --https=<port> http://localhost:<port>
  - Uses foreground mode so process can be killed to stop serving
  - Returns TunnelHandle with URL https://<hostname>
- Added stop_serve() public method for explicit cleanup via tailscale serve off
- Added comprehensive unit tests for:
  - Hostname parsing (with/without trailing dot, missing fields, invalid JSON)
  - Login status parsing (Running, Stopped, NeedsLogin, Starting states)
  - URL construction

Validation

cargo build          ✓
cargo test           ✓ (128 tests passed - 121 unit, 7 integration)
cargo clippy         ✓ (no warnings)
cargo fmt --check    ✓

Acceptance Criteria

TailscaleTunnel implements TunnelProvider
is_available() checks for tailscale binary and logged-in status
spawn() runs tailscale serve <port> and constructs URL from hostname
Properly cleans up serve on drop (process kill stops foreground serve)

Notes

Tailscale serve only shares within your tailnet (private network), not publicly on the internet
The serve uses HTTPS on port 443 by default, regardless of the local port being proxied
Using --bg=false keeps the serve in foreground mode, so killing the process stops the serve

2026-01-29 - Story 9: ngrok tunnel implementation

- Implemented full spawn() method:
  - Spawns ngrok http <port> command
  - Supports auth token via NGROK_AUTHTOKEN environment variable
  - Attempts to read URL from stdout (newer ngrok versions)
  - Falls back to querying ngrok's local API at http://localhost:4040/api/tunnels
  - Prefers HTTPS tunnels over HTTP
  - Handles timeout and process exit errors
  - Returns TunnelHandle with running process and public URL
- Added comprehensive unit tests for URL parsing from both stdout and API
