* feat(desktop): auto-discover Honcho instances on localhost
First-launch and on-demand discovery of running Honcho instances on
127.0.0.1:8000-8100. Desktop-only — the browser can't port-scan due to
CORS, so the scan runs in the Tauri Rust shell.
- New Rust command `discover_honcho_instances(start_port?, end_port?)`
in src-tauri/src/discover.rs: parallel TCP probe of each port with
150ms connect timeout + 250ms total request budget, looking for a
/health endpoint returning `{"status":"ok"}`.
- New TS helper `discoverHonchoInstances()` in src/lib/discovery.ts:
detects Tauri runtime; web build degrades to an empty result.
- `suggestNameForInstance()` fetches the first workspace and derives a
friendly name from its id ("neo-personal" -> "Neo"). Used to seed the
Name field for each discovered instance.
- `DiscoveredInstances` component: list of found instances with
editable suggested names + per-row checkbox + "Add N instances"
button. Rows are pre-checked by default and filter out already-
configured baseUrls.
- Wired into `InstancesManager`:
- First launch (no instances): renders above the connection-type
chooser with autoRun=true. User sees results immediately.
- With instances: adds a "Discover instances" button to the list
view that opens the discovery flow on demand.
- Both paths gate on `isTauri()`; the web build keeps its existing
behaviour unchanged.
Adds tokio (with net + io-util + time + rt + macros) and futures to
the Tauri shell to get async TCP + join_all.
Tests:
- deriveNameFromWorkspaceId handles hyphenated, multi-segment, and
no-hyphen ids
* test(desktop): add probe tests including live Hermes stack integration
- rejects_inverted_port_range
- ignores_ports_with_no_listener
- finds_live_hermes_stacks (#[ignore]d; opt-in with --ignored)
The ignored test exercises discover_honcho_instances against ports
8000-8010, expecting exactly [8001, 8002, 8003, 8004, 8005]. Verified
locally — the probe finds all 5 stacks in <10ms.
