Backend: GET /health/dwh (unauthenticated) calls tht db ping with a 5s
timeout. Frontend: checkDwhHealth() races a 5s timer against the fetch;
on failure a non-dismissable Dialog with Retry appears immediately.

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).

Live end-to-end surfaced a 500 on every tht call: ThtRunner prepended
'-c <config>' before the subcommand, but tht has no global -c option
('No such option: -c'). --config/-c is a per-command option, so it must be
appended AFTER the subcommand. Extracted buildArgv() and fixed the unit test
that had codified the wrong (prepended) order.

Harness:
- preview_cmd FILE positional arg made optional; when omitted with --session,
path is derived via _session_sql_file (mirrors export_cmd) — fixes the
deferred Task-5 bug where the backend passed sessions/<id>/sql_final.sql
relative to harnessDir, which broke for workspace-dependent paths.
- New pytest: test_preview_session_no_file_resolves_sql_final
Backend:
- ThtRunner.sqlPreview: drop positional file arg; use --session only
- New routes/sql.ts: POST /sessions/:id/sql/preview + /export
- New routes/meta.ts: GET /workspaces (yaml scan) + GET /models (injectable
seam + graceful fallback to {models:[]})
- app.ts: register sqlRoutes + metaRoutes; add listModels to BuildAppDeps
- tht-runner.test.ts: add sqlPreview argv assertion (no file path)
- test/routes-sql-meta.test.ts: 9 tests (sql preview/export + meta routes)
Tests: harness 233 passed; backend 29 passed; build clean.

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.
