Audit findings 4.1-4.6.
- spawnFor: a rejected configure/start no longer leaks a registered runtime
with a live Pi child (identity-checked teardown + rethrow); every later
start used to hit "session runtime already active".
- ThtRunner.run: default 60s timeout on every tht child (SIGKILL backstop),
120s for DWH-touching calls (sql preview/export, search pack); a dropped
VPN mid-call no longer wedges the HTTP request forever.
- configArg: a NAMED workspace whose yaml is missing now throws instead of
silently falling back to the default config (operations were silently
targeting the wrong workspace).
- resume: the finalized/archived 409 is evaluated BEFORE the alreadyActive
fast-path — the manifest is the truth even with a lingering runtime.
- ollamaEnsure: exit-0 with non-JSON stdout is a failed check, not ok:true.
- SessionBridge.respond: only the response matching the pending descriptor
is forwarded to Pi; stale/duplicate submissions return 409 instead of
being sent with the current gate's RPC id.

New session now refuses to spawn a Pi runtime that would only die in bootstrap
retrieval when the DWH/vector host is unreachable (e.g. a dropped VPN). Before
`session new`, POST /sessions probes the DWH via `tht db ping`; if it is down it
returns 503 {code:"dwh_unreachable"} with a clear message and creates nothing.
- Gated behind the THT_DWH_PRECHECK flag (default off), enabled only by the local
dev launcher (run-stack.sh) — containers/CI never pay the probe, and existing
tests that don't set it are unaffected.
- ThtRunner.dbPing() runs `tht db ping` with a 10s timeout (run() gains an optional
timeout that SIGKILLs a hung child).
- Frontend: apiFetch throws a typed ApiError (status + parsed payload); the new-
session composer shows the specific alert on `dwh_unreachable` instead of the
generic retry hint, keeping the question for retry.
Verified live on an isolated backend (precheck on + broken DWH host → 503
dwh_unreachable, no session created) and via unit tests (backend 228, frontend 308).

Opening an in-progress session that has a live Pi runtime now reconnects to
its pending gate instead of the empty landing screen that read as "stopped".
Cold/completed sessions keep the read-only documents panel with its explicit
Resume, so a mere click never spawns a runtime. Backend GET /sessions now
reports a per-session `active` flag (live runtime bound) to drive this.
Also:
- "New session" now closes any open session detail panel (left box).
- The model-activity separator can be dragged to a full 50/50 split
(was capped at 576px); central-min still guards narrow viewports.
Test fixes uncovered along the way:
- Node 25 ships an experimental global localStorage that shadows jsdom's and
lacks clear(), failing every jsdom test at setup; install a spec-compliant
in-memory Storage (feature-detected, inert on CI/LTS).
- Fix 4 pre-existing session-mgmt tests that used an ambiguous getByText for a
session shown in both nav and header; target the nav item by test id.

workspace/provider/model/thinking now come from getSettings() injected into
sessionRoutes; the request body supplies only question+name. Also teaches
fake_pi_rpc to respond to set_model and set_thinking_level RPC commands so
tests that pass real model settings don't hang.

POST /sessions no longer silently drops `workspace`. ThtRunner.run/json
take an optional workspace; configArg() selects workspaces/<ws>.yaml when
it exists under harnessDir, else falls back to default configPath.
sessionNew threads workspace through. Route forwards b.workspace with an
MVP note (gate/Pi side still single-workspace via symlinked config/tht.yaml).
19/19 tests pass, tsc clean.

Make buildApp injectable (deps.thtRunner + deps.spawnFn); create
src/routes/sessions.ts with all 7 session routes under authPreHandler;
wire bridge.onClientEvent→hub.publish before returning {id} from POST
/sessions; SSE subscribes with pendingWidget safety net.
18/18 tests pass, tsc clean.
