Two enhancements requested after live-validating PR #430 against a real
llama.cpp server:
1. Model picker dialog. Picking a Run-menu Custom Endpoints entry used to
apply the endpoint's defaultModelId (or the first discovered model)
silently. Now, via the new selectCustomModelEntry() (session-ui.js):
- exactly one discovered model launches straight away, same as before
- two or more open a new #customModelPickModal listing every discovered
model; defaultModelId (if set) is marked but never auto-chosen, since
the point of asking is letting ONE launch deliberately differ from
the saved default, not just confirming it
The endpoint is re-fetched at click time rather than trusting anything
cached from the dropdown's own render, since the model list can have
changed (the sweep below, or a settings-panel edit) since it opened.
runCustomModelEntry() itself — the actual launch, routed through run()
for the in-flight lock, snapshot-guarded against applying to the wrong
session — is unchanged; it now just always receives an explicit model
id from one of these two paths instead of computing one itself.
2. Periodic re-discovery. Every saved endpoint's models now refresh
automatically every 5 minutes in the background
(CUSTOM_MODEL_REDISCOVER_INTERVAL_MS, server.ts, registered the same way
as the Codex plan-usage poll it sits beside — this.cleanup.setInterval,
off under testMode), so a model the server starts or stops serving shows
up without another manual "Discover" click. The manual POST
.../discover-models route and the new refreshAllCustomModelHosts()
sweep (custom-model-routes.ts) now share one pure merge step
(applyDiscoveredModels: stamps lastDiscoveredAt, drops a defaultModelId
that no longer appears) rather than two copies that could drift. The
sweep is best-effort per host — one endpoint being unreachable on a
cycle never blocks the others — and re-reads the store before each
host's write, keyed by id, so a concurrent edit or delete from the
settings panel always wins over a sweep that started before it.
Tests: test/custom-model-endpoint-rediscovery.test.ts is a new, dedicated
file for the sweep (kept separate from custom-model-routes.test.ts because
that file's data dir is shared across every test in it — one temp HOME per
FILE, not per test — which would make a sweep-touches-every-host assertion
meaningless there). test/custom-model-run-menu-ui.test.ts gained a new
describe block driving the real picker modal through JSDOM: single-model
bypass, multi-model dialog with the default marked-not-chosen, picking a
row closes the modal and launches with that exact model, the endpoint
re-fetch, and the two "vanished by click time" toast paths.
Docs: docs/custom-model-endpoints.md, docs/wiki/Custom-Model-Endpoints.md,
docs/api-reference.md and CLAUDE.md's dense feature paragraph all updated
— the last of these also caught up two sentences that had gone stale after
the draft-review fixes landed (the picker routes through run() now, not a
raw run*() call).
