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).

Unisce gli internals di Codex (secret-bundle, provider-credentials, auth upstream,
security hardening, CI multiarch) mantenendo le fix portal-specific:
- backend: configPath da THT_CONFIG (fix sessioni) + dataRoot di Codex; authMode 'upstream'
- Docker/compose: TENUTO il mio (verificato live: omics_network+alias, env_file, pi npm-g)
perche' il compose/Dockerfile/entrypoint di Codex sono accoppiati al suo modello
secret-bundle (tht doctor inesistente, secret-policy.sh). Adottabile in futuro.
- config.test.ts: preso Codex (superset)
Verificato: tsc clean, 132/132 vitest.
