Closes #2027.

Problem

When a workspace names a runtime (e.g. google-adk) but that runtime's workspace template isn't in the tenant cache at provision time — or sanitizeRuntime coerces an unknown runtime — config seeding silently falls back to the claude-code-default template. The image + env are correct (google-adk, Vertex), but the seeded config.yaml says runtime: claude-code and ships no persona/system-prompt.md. The agent boots mislabeled and personaless yet looks 'online', and returns canned non-answers. This hit the molecule-adk-demo hackathon org (all 4 google-adk agents).

Fix

Add a fail-loud preflight in prepareProvisionContext (shared by the Docker + SaaS provision paths) — the symmetric counterpart to selectImage's existing ErrUnresolvableRuntime guard, on the config/template side:

If a workspace requested a non-empty runtime but the config.yaml about to be seeded declares a different top-level runtime:, abort the provision (WORKSPACE_PROVISION_FAILED + last_sample_error) instead of launching a mislabeled agent.

The single check catches both failure modes (template-cache fallback and sanitizeRuntime coercion), because both surface as a seeded config whose runtime contradicts the request. Conservative by design:

empty requested runtime (unspecified / org-template default path) → allowed
indeterminate seeded runtime (CP mode, no local config bytes) → allowed
only a concrete, contradictory signal fails.

The error message points the operator at the remedy (POST /admin/templates/refresh + re-provision).

Tests

workspace_provision_runtime_seed_test.go: parseTopLevelRuntime (top-level vs nested runtime_config, quoting, absence), seededConfigRuntime (configFiles vs template-dir vs indeterminate), and runtimeSeedMismatchAbort (mismatch fails / match ok / empty ok / indeterminate ok / template-dir mismatch fails). Full internal/handlers package green; go vet + -tags=integration build clean.

Follow-up (not in this PR)

Re-seeding/repairing already-provisioned workspaces whose config drifted (the 4 demo agents were hand-repaired and verified answering via ADK→Vertex→Gemini 2.5 Pro).

SOP checklist (RFC#351) — Tier: low

Tier rationale: additive, fail-closed provisioning preflight; fully unit-tested; no schema/security/identity/fleet-image surface; reduces risk (turns silent breakage into loud failure).

Comprehensive testing performed — unit tests for parseTopLevelRuntime / seededConfigRuntime / runtimeSeedMismatchAbort (mismatch/match/empty/indeterminate/template-dir); full internal/handlers package green; go vet + -tags=integration build clean.
Local-postgres E2E run — internal/handlers (incl. provision paths) green locally; the guard is a pure pre-Start check covered by unit tests; Handlers Postgres Integration CI exercises the DB path.
Staging-smoke verified or pending — root cause verified live on the molecule-adk-demo tenant (4 google-adk agents repaired + answering via ADK→Vertex→Gemini 2.5 Pro); this guard prevents recurrence. Staging-smoke via CI.
Root-cause not symptom — fixes the silent claude-code-default fallback at the provision choke point (prepareProvisionContext), symmetric to selectImage's ErrUnresolvableRuntime; not the downstream symptom.
Five-Axis review walked — correctness (contradiction-only fail), security (no new surface; reads config bytes already in hand), perf (one in-mem/file read at provision), observability (WORKSPACE_PROVISION_FAILED + last_sample_error pointing at the remedy), tests (all classes).
No backwards-compat shim / dead code add — pure additive guard; conservative (empty/indeterminate allowed) → no behavior change for valid provisions.
Memory/saved-feedback consulted — built integration tag before push; gofmt only edited files; checked for parallel work; recorded the diagnosis in feedback memory.

When a workspace NAMES a runtime but the config.yaml about to be seeded
declares a different top-level runtime, refuse to launch and surface
WORKSPACE_PROVISION_FAILED — the symmetric counterpart to selectImage's
ErrUnresolvableRuntime guard, on the config/template side.

Pre-fix: if a runtime's workspace template wasn't in the tenant cache at
provision time (or sanitizeRuntime coerced an unknown runtime), config
seeding silently fell back to claude-code-default. The image+env said
e.g. google-adk but the seeded config said claude-code, so the agent
booted mislabeled and personaless yet looked 'online' and returned canned
non-answers (hit the molecule-adk-demo hackathon org: 4 google-adk agents).

The guard is in prepareProvisionContext (shared by Docker + SaaS paths).
Empty requested runtime (org-template default path) and an indeterminate
seeded runtime (CP mode, no local config bytes) are both allowed — it only
fails on a concrete, contradictory signal.

Fail-loud guard mirrors selectImage ErrUnresolvableRuntime; conservative (only fails on concrete contradiction); tests cover all classes; handlers package green. LGTM.

Security: no new attack surface — guard reads config bytes already in hand; path-traversal still handled upstream by resolveInsideRoot/sanitizeRuntime allowlist. Approved.
