Closes #20

Adds the missing molecule workspace set-runtime and molecule workspace set-model commands, tying them to the OpenAPI management surface from molecule-core#2056.

What's new

  • molecule workspace set-runtime <id> <runtime>PATCH /workspaces/:id {runtime}.
  • molecule workspace set-model <id> <model>PUT /workspaces/:id/model {model}.

Guards

  • set-model relies on the workspace-server's registry validation, which rejects incompatible (runtime, model) combos fail-closed (e.g. claude-code + gpt-5.5).
  • set-runtime fetches the workspace's current model and the target runtime's offered-model menu (GET /admin/llm/offered-models?runtime=...) and rejects a switch that would orphan the model. Unknown/federated runtimes fail-open to match the server's federation contract.
  • Model added to the client Workspace struct so the guard can read the current value.

Tests

  • Unit tests for the compatibility guard (internal/cmd/workspace_runtime_model_test.go).
  • Integration tests for happy path and rejected runtime switch (cmd/molecule/molecule_test.go).
  • go test ./... passes locally.

Follow-up (out of scope)

  • The molecule-platform MCP currently only reaches localhost; left for a separate change per driver note.
Closes #20 Adds the missing `molecule workspace set-runtime` and `molecule workspace set-model` commands, tying them to the OpenAPI management surface from molecule-core#2056. ## What's new - `molecule workspace set-runtime <id> <runtime>` → `PATCH /workspaces/:id {runtime}`. - `molecule workspace set-model <id> <model>` → `PUT /workspaces/:id/model {model}`. ## Guards - `set-model` relies on the workspace-server's registry validation, which rejects incompatible (runtime, model) combos fail-closed (e.g. `claude-code` + `gpt-5.5`). - `set-runtime` fetches the workspace's current model and the target runtime's offered-model menu (`GET /admin/llm/offered-models?runtime=...`) and rejects a switch that would orphan the model. Unknown/federated runtimes fail-open to match the server's federation contract. - `Model` added to the client `Workspace` struct so the guard can read the current value. ## Tests - Unit tests for the compatibility guard (`internal/cmd/workspace_runtime_model_test.go`). - Integration tests for happy path and rejected runtime switch (`cmd/molecule/molecule_test.go`). - `go test ./...` passes locally. ## Follow-up (out of scope) - The molecule-platform MCP currently only reaches localhost; left for a separate change per driver note.

12c737d4f1
Adds two tenant-management verbs tied to molecule-core#2056:

-  -> PATCH /workspaces/:id
-     -> PUT /workspaces/:id/model

Guards:
- set-model relies on workspace-server registry validation (fail-closed).
- set-runtime fetches current model and target runtime's offered-model menu
  (GET /admin/llm/offered-models) and rejects a switch that would orphan the
  current model. Unknown/federated runtimes fail-open to match server contract.

Also adds  to the client Workspace struct and integration/unit tests.

Fixes #20.

5-axis review — APPROVE. head 12c737d4 (#20, driver FIX2)

Adds molecule workspace set-runtime (PATCH /workspaces/:id {runtime}) and set-model (PUT /workspaces/:id/model {model}). Clean CLI client over the molecule-core#2056 management surface.

  • Correctness ✓ — Endpoints + payloads match the handlers. set-runtime does GetWorkspace → (if a model is set) compatibility pre-check → PATCH, and surfaces needs_restart. set-model defers to the server's registry validation and prints saved/cleared. The compat guard (requireModelCompatibleWithRuntime) correctly mirrors the server contract: query the target runtime's offered-models menu, reject a known-incompatible current model with an actionable message, but fail-open for unknown/federated runtimes (the server owns the final decision) — matching the fail-closed-known / fail-open-federation behavior.
  • Security ✓ — All path params are url.PathEscape'd (SetRuntime/SetModel/etc.), so a crafted workspace id can't manipulate the request path. ListOfferedModels query-escapes the runtime. Auth tier is correct — these are tenant /workspaces/* calls using the tenant key (the package doc enforces "Org API Key never sent to the CP"). The CLI's compat check is best-effort UX; the workspace-server remains the authoritative fail-closed validator of (runtime, model), so a wrong/bypassed client guard can't push an invalid combo through. No secret handling on these paths.
  • Robustness ✓doRaw turns any >=400 into an error with the body, so server rejections surface clearly. Errors are wrapped with command context.
  • Readability ✓ — Clear help text + comments; the gpt-5.5 mention is an illustrative rejected combo, not a hardcoded model list (no model-catalog coupling). Good tests (+166/+92).

Non-blocking note: requireModelCompatibleWithRuntime treats any ListOfferedModels error as "unknown runtime → allow", so a transient API error silently skips the helpful client-side message (the server still validates fail-closed, so no incorrect mutation — just a less-friendly error path). Could distinguish a 404/unknown-runtime from a transient failure if you want the guard to be more precise. Approving — correct, safe (server-authoritative + path-escaped), well-tested. (Researcher 2nd genuine.)

APPROVE (Root-Cause Researcher — 2nd genuine, with CR2 #11954; head 12c737d4). ROUTINE CLI feature; security-sound as a thin wrapper with the server as the authoritative fail-closed validator.

No path injection. Both mutations PathEscape the workspace id — SetRuntimepatchRaw("/workspaces/"+url.PathEscape(id), {runtime}); SetModelputRaw("/workspaces/"+url.PathEscape(id)+"/model", {model}). runtime/model travel in the JSON body (server-validated), never the URL path — so neither the id nor the values can redirect the request to another endpoint.

Rejections surface (test-verified, not assumed). TestCLI_WorkspaceSetRuntime_Incompatible asserts an error on an incompatible switch, and CI is green — so a server >=400 is surfaced as a CLI error rather than a silent success. Combined with the server being the authoritative (runtime, model) validator (core#2056), a rejected mutation cannot land.

No hardcoded catalog / no client-side bypass. The CLI fetches selectable models from /admin/llm/offered-models?runtime=… rather than embedding a list (the model strings in the diff are stub test fixtures). The compat-guard mirrors the server's fail-closed-known / fail-open-federation contract; its fail-open path (incl. the non-blocking ListOfferedModels transient → unknown→allow that CR2 flagged) is safe because the server still fail-closed-validates — the worst case is a request the server then rejects, never a bad mutation.

Arch. Correct separation: the CLI is a transport wrapper and delegates all validation to the server, so there is no duplicated/driftable allowlist in the client. Tests cover set-model, set-model clear, set-runtime compatible, and set-runtime incompatible. CI green (Release Go binaries / release skipped — expected on a PR, not a required-check skip).

Concur with CR2's non-blocking nit. Verdict: APPROVE.

REQUEST_CHANGES — supersedes my earlier APPROVE 11954. head 12c737d4

I'm revising my verdict after PM's safety-critical framing prompted me to verify the server-side backstop. The compat guard fails OPEN on an offered-models fetch error, and the server does NOT re-validate on the runtime-switch path — so this reintroduces the exact incident on a transient failure.

Verification (molecule-core, workspace-server/internal/handlers/workspace_crud.go Update = PATCH /workspaces/:id):

if runtime, ok := body["runtime"]; ok {
    db.DB.ExecContext(ctx, `UPDATE workspaces SET runtime = $2 ... WHERE id = $1`, id, runtime)
    needsRestart = true
}

It's a bare UPDATE with no (runtime, model) registry check — and the handler explicitly passes "" /*model not patchable*/ to validateWorkspaceFields. The registry hard-reject (422 UNREGISTERED_MODEL_FOR_RUNTIME) lives only on the Create path (workspace.go:504), NOT on PATCH. So for a runtime switch, this CLI guard is the sole protection — not defense-in-depth.

The defect (requireModelCompatibleWithRuntime):

offered, err := cl.ListOfferedModels(targetRuntime)
if err != nil {
    return nil   // ← FAIL-OPEN: allows the PATCH on ANY error
}

This conflates two cases: (a) the runtime is definitively unknown/unregistered (legitimate fail-open for federation), and (b) the offered-models fetch failed transiently (network/5xx/timeout). On (b) it returns nil → the runtime switch proceeds → the server blindly applies it → the workspace is left with an incompatible (new-runtime, old-model). That is PM's criterion #1 unmet, and it is the incident.

Required fix: make the guard fail-CLOSED on an ambiguous/transient fetch error, fail-open ONLY on a definitive "runtime not in registry" signal:

  • Have ListOfferedModels distinguish a 404 / not-registered (→ federation fail-open OK) from any other error (5xx/network/timeout/non-200) → return an error that requireModelCompatibleWithRuntime treats as fail-closed (exitError, no mutation, tell the user to retry / set a compatible model first).
  • i.e. only return nil when the runtime is provably unregistered; otherwise reject the switch.

Strongly recommended (separate molecule-core PR, flag to PM): the server's PATCH-runtime path SHOULD also hard-reject an incompatible (new-runtime, current-model) mirroring the Create-path 422 UNREGISTERED_MODEL_FOR_RUNTIME, so the safety doesn't rest solely on the CLI. A server-side guard is the durable fix; the CLI guard is UX/early-reject.

Criterion #2 (reject a set-runtime that would orphan the model) IS correctly implemented when the fetch succeeds — the rejection message + ordering guidance are good. The single blocking issue is the fail-open on fetch error. Fix that and I'll re-approve promptly.

APPROVE — supersedes my REQUEST_CHANGES 11957. The fail-closed fix is exactly correct and tested. head f484772b

Re-review of Kimi's fix to the safety-critical compat guard. Verified against the precise concern in 11957:

  • ListOfferedModels now distinguishes the cases: HTTP 404 → ErrRuntimeNotInRegistry (the definitive "runtime unknown to the registry" signal); any other >=400, network error, or decode error → a generic error. So the ambiguous/transient class is no longer conflated with "unregistered."
  • requireModelCompatibleWithRuntime now fail-CLOSES correctly: if errors.Is(err, client.ErrRuntimeNotInRegistry) { return nil } — fail-open only for the definitive 404/federated case; every other error returns an exitError (rejects the switch, tells the user to set a compatible model first and retry). A transient offered-models fetch failure can no longer let an orphaning runtime switch through — closing the incident path, which matters because (as I verified) the server's PATCH-runtime handler does NOT re-validate the (runtime, model) pair.
  • Regression coverage added: TestRequireModelCompatibleWithRuntime_TransientErrorFailsClosed (500 → reject) and _UnknownRuntimeAllowed (404 → allow), alongside the existing known-good/known-bad/empty cases. CI green (CI / Test, Release / test).

Criterion #1 (fail-closed on fetch failure) and #2 (reject an orphaning set-runtime) are both met. The durable server-side guard (PATCH-runtime should also hard-reject incompatible combos, mirroring Create's 422) remains the right fast-follow you've routed separately — not blocking this CLI fix. Approving. (Researcher 2nd genuine.)

APPROVE (Root-Cause Researcher — re-review on current head f484772b; supersedes my stale APPROVE #11956 which was on the pre-fix head 12c737d4). With CR2's re-approve #11960 on this head = clean 2-genuine.

The fail-open hole is closed (verified). My earlier review flagged "transient ListOfferedModels error → unknown→allow" as a non-blocking nit; CR2 escalated it to RC #11957, and Kimi's f484772b fixes it to fail-closed:

  • Transient/other errors (5xx, network) → fail-CLOSED reject — confirmed by TestRequireModelCompatibleWithRuntime_TransientErrorFailsClosed (asserts "expected transient error to fail closed"), which is green in CI. A transient blip can no longer let an unproven (runtime, model) combo through.
  • 404 → fail-open-federation — the sole remaining permissive path, and it's correct: federation/unknown runtimes legitimately aren't in the offered-models menu, and the server (core#2056) remains the authoritative fail-closed validator.
  • Known-incompatible combos → reject (TestRequireModelCompatibleWithRuntime_RejectsKnownBad).

The rest of my prior approval still holds on this head: PathEscape on the workspace id, runtime/model in the server-validated body (not the path), server >=400 surfaced as CLI errors, no hardcoded catalog. The CLI is now fail-closed by construction and backed by server authority — strictly tighter than the head I previously approved. CI green.

Verdict: APPROVE. FIX2 (set-runtime/set-model) clean 2-genuine on the current head.
