Why

Empirical trigger: Code Reviewer 5ba15d7e was created with {"name":"Code Reviewer","runtime":"codex","tier":4,...} — no model field. The legacy models.DefaultModel("codex") returned "anthropic:claude-opus-4-7". Codex adapter only supports openai-* providers, so the workspace wedged forever in not_configured with:

ValueError: codex adapter: workspace config picks provider='anthropic' but it is not in the providers registry

PATCH /workspaces/:id explicitly disallows updating model (workspace_crud.go:138 — model not patchable), so the only recovery path was SQL UPDATE or delete+recreate. Five-team rollout uncovered this when the agents-team production-team failed at 4/5.

SSOT directive

CTO 2026-05-22T03:42Z: model is REQUIRED user input at create. Platform does not provide a default. Runtime does not fall back. The decision belongs to the user (or to the agent acting on the user's behalf) — never to the platform. Soft fallbacks hide contract bugs; this is the canonical example.

Filed as user-level feedback memory feedback_workspace_model_required_no_platform_default_dynamic_credential_intake.

What

• DELETE models.DefaultModel (runtime_defaults.go). The function is the bug magnet.
• Create handler MODEL_REQUIRED gate: 422 with code=MODEL_REQUIRED, runs AFTER template-resolution and the runtime-default-to-langgraph path. Same fail-closed shape as the existing controlplane#188 runtime-unresolved gate.
• ensureDefaultConfig: drop the DefaultModel call. Log loudly if empty model reaches here (defence-in-depth — the Create gate should have rejected upstream).
• org_import.go createWorkspaceTree: drop the DefaultModel call. Org templates MUST declare model: per-workspace or under defaults:; otherwise the import errors instead of silently provisioning a runtime-incompatible workspace.
• New test: TestCreate_ModelRequired_Returns422 covers three trigger shapes (bare name; explicit codex+no-model; explicit hermes+no-model). All three return 422 code=MODEL_REQUIRED.
• Updated: TestWorkspaceCreate now passes explicit model; runtime_defaults_test.go reduced to a doc-comment file (compile-time check is the contract).

Out of scope (follow-up commit on this branch)

~20 existing tests pin the OLD DefaultModel contract and now fail. Holding the test surgery for a second commit so reviewers can sanity-check the contract change against the inventory below before we churn 20+ tests.

(a) Mechanical (add "model":"..." to request body)

Exercise unrelated invariants (parent_id, SSRF, secrets, tier, runtime label, etc.) and would pass once an explicit model is supplied:

• TestWorkspaceCreate_WithParentID
• TestWorkspaceCreate_ExplicitClaudeCodeRuntime
• TestWorkspaceCreate_MaxConcurrentTasksOverride
• TestWorkspaceCreate_DBInsertError
• TestWorkspaceCreate_DefaultsApplied
• TestWorkspaceCreate_SaaSHardForcesTier4
• TestWorkspaceCreate_WithSecrets_Persists
• TestWorkspaceCreate_SecretPersistFails_RollsBack
• TestWorkspaceCreate_EmptySecrets_OK
• TestWorkspaceCreate_ExternalURL_SSRFSafe / _SSRFMetadataBlocked / _SSRFLoopbackBlocked
• TestWorkspaceCreate_KimiRuntime_PreservesLabel
• TestWorkspaceCreate_188_ExplicitRuntimeNoTemplate_OK
• TestWorkspaceBudget_Create_WithLimit

(b) Semantic — pin the OLD contract, need rewrite or deletion

• TestEnsureDefaultConfig_Hermes / _ClaudeCode / _EmptyRuntimeDefaultsToClaudeCode — assert YAML contains the DefaultModel-derived string. Either pass explicit model in the payload, or drop the model-string assertion (YAML now reflects whatever the caller supplied).
• TestWorkspaceCreate_FirstDeploy_NoModel_NoSecretWritten — literally asserts that empty model is a 201 with no secrets written. Under the new contract empty model is a 422 with no DB writes at all. Invert the test: now asserts the 422 + no-DB-write outcome.
• TestWorkspaceCreate_188_NoTemplateNoRuntime_StillDefaultsLanggraph — premise was "bare {name} defaults to langgraph 201". Now bare {name} is a 422 because model is missing. Premise changes to "bare {name} fails MODEL_REQUIRED before runtime resolution".

Memory

• feedback_workspace_model_required_no_platform_default_dynamic_credential_intake — the contract
• feedback_three_layer_data_responsibility_platform_base_adaptor — platform-half of the same principle
• feedback_never_probe_destructive_http_verbs_on_prod — neighbouring incident from the same session

Test plan

• go build ./... clean
• go test ./internal/models/... — pass
• go test -run 'TestCreate_ModelRequired_Returns422' ./internal/handlers/ — pass
• Follow-up commit: cascade-update the (a) and (b) tests above; full ./internal/handlers/... green
• Reviewer sanity-check the inventory above against the contract change

Coordinated follow-ups

• Code Reviewer recovery (separate path): SQL UPDATE workspaces SET model='gpt-5.5' WHERE id='5ba15d7e-fd2b-44a0-989b-e7fbab1bc1a8'; + restart. The Create-side fix here would prevent the recurrence but doesn't unbreak the already-stuck workspace.
• PATCH /workspaces/:id model not patchable (workspace_crud.go:138): re-enable model PATCH at least for the broken-codex-default recovery case. Likely follow-up PR.
• Provider/credential intake subsystem (CP IAM-like): the second half of the CTO directive. Filed as RFC follow-up; this PR is scoped to just the model field.

feat(workspace-server): kill DefaultModel + require model at Create (CTO 2026-05-22 SSOT) ... f8e031a971

Empirical trigger: Code Reviewer 5ba15d7e was created with
`{"name":"Code Reviewer","runtime":"codex","tier":4,...}` — no model
field. The legacy `models.DefaultModel("codex")` returned
`"anthropic:claude-opus-4-7"`. Codex adapter only supports openai-*
providers, so the workspace wedged forever in `not_configured` with:

    ValueError: codex adapter: workspace config picks provider='anthropic'
    but it is not in the providers registry

PATCH /workspaces/:id explicitly disallows updating `model`
(workspace_crud.go:138 — `model not patchable`), so the only recovery
path was SQL UPDATE or delete+recreate.

CTO 2026-05-22T03:42Z SSOT directive: model is REQUIRED user input at
create time. The platform must not provide a default. The runtime must
not fall back. The decision belongs to the user (or to the agent acting
on the user's behalf), never to the platform. Soft fallbacks hide
contract bugs — this is the canonical example.

Changes:

- DELETE `models.DefaultModel` (runtime_defaults.go). The function is
  the bug magnet — every callsite that previously fell back to it now
  fails closed.

- `handlers.WorkspaceHandler.Create` (workspace.go): add MODEL_REQUIRED
  gate AFTER template-resolution and AFTER the runtime-default-to-langgraph
  path. Caller gets 422 with `code=MODEL_REQUIRED` and a hint message
  pointing at the contract. Same fail-closed shape as the existing
  controlplane#188 runtime-unresolved gate.

- `ensureDefaultConfig` (workspace_provision.go): drop the DefaultModel
  call. If we ever reach this path with empty model, log loudly and let
  the workspace boot into not_configured — defence-in-depth assertion;
  the Create gate should have rejected the request upstream.

- `org_import.go createWorkspaceTree`: drop the DefaultModel call. Org
  templates MUST declare `model:` per-workspace or under `defaults:` —
  return an error otherwise. Stops malformed templates from silently
  provisioning runtime-incompatible workspaces.

- Tests: add `TestCreate_ModelRequired_Returns422` covering the three
  trigger shapes (bare name; explicit codex+no-model; explicit hermes+no-model).
  Update `TestWorkspaceCreate` to pass an explicit model (was a bare-defaults
  201 test — now requires explicit model to express the new contract).
  Reduce `runtime_defaults_test.go` to a doc-comment file (function
  doesn't exist anymore; compile-time check is the contract).

Known blast radius — DELIBERATELY NOT FIXED IN THIS COMMIT, surfaced
for triage:

The CTO directive inverts the prior contract; ~20 existing tests pin
the OLD behaviour and now fail. They fall into two buckets:

  (a) Mechanical: add `"model":"..."` to request body. These tests
      exercise unrelated invariants (parent_id, SSRF, secrets, tier,
      runtime-label preservation, etc.) and would still pass once
      they supply an explicit model. ~15 tests in handlers_additional_test.go,
      registry_test.go, handlers_test.go, etc.

  (b) Semantic: these tests pinned the OLD contract directly and need
      rewriting or deletion:
        - `TestEnsureDefaultConfig_Hermes` / `_ClaudeCode` /
          `_EmptyRuntimeDefaultsToClaudeCode` — assert the YAML output
          contains the DefaultModel-derived string. Either pass an
          explicit model in the payload, or drop the YAML model
          assertion (it now reflects whatever the caller supplied).
        - `TestWorkspaceCreate_FirstDeploy_NoModel_NoSecretWritten` —
          literally asserts that empty model is a 201, just with no
          secrets written. Under the new contract empty model is a
          422 with no DB writes at all. Test should be inverted to
          assert the 422 + no-DB-write outcome.
        - `TestWorkspaceCreate_188_NoTemplateNoRuntime_StillDefaultsLanggraph`
          — premise was "bare {name} should default to langgraph 201".
          Now bare {name} is a 422 because model is missing. Premise
          changes to "bare {name} now fails MODEL_REQUIRED before
          runtime resolution".

Holding the test surgery for a follow-up so reviewers can sanity-check
the contract change against the inventory above before we churn 20+
tests. Marking DRAFT until that follow-up lands.

test(workspace-server): cascade test updates for MODEL_REQUIRED contract ... 1ece444ea2

Follow-up to the prior commit (kill DefaultModel + 422 at Create when
model missing). Fixes the two test buckets called out in the DRAFT PR
description.

(a) Mechanical: add `"model":"..."` to request bodies so tests can
still reach the 201 path. These tests exercise unrelated invariants
(parent_id wiring, claude-code runtime label, max_concurrent_tasks
override, DB insert error rollback, defaults, SaaS tier-4 force, with-
and-without secrets persistence/rollback, external SSRF gates, Kimi
runtime label preservation, controlplane#188 explicit-runtime path,
budget limit). Model strings picked from the same set the prior
DefaultModel(runtime) would have returned (`sonnet` for claude-code,
`anthropic:claude-opus-4-7` elsewhere) plus `gpt-5.5` for codex,
`kimi-coding/kimi-k2-coding-6` for kimi, `external:custom` for the
external runtime — so the tests exercise realistic shapes, not just a
single placeholder.

(b) Semantic — the three tests that pinned the OLD contract directly:

  - `TestEnsureDefaultConfig_Hermes` / `_ClaudeCode` /
    `_EmptyRuntimeDefaultsToClaudeCode` — the function no longer
    sources the default; it just renders what Create supplied. Each
    test now passes the model that the prior implicit DefaultModel
    branch would have returned, so the YAML assertion remains
    meaningful. Comment updated to explain the shift.

  - `TestWorkspaceCreate_FirstDeploy_NoModel_NoSecretWritten` was
    renamed `TestWorkspaceCreate_FirstDeploy_NoModel_Returns422` and
    its premise INVERTED. Pre-fix it asserted that empty model goes
    through to 201 with no workspace_secrets writes; post-fix it
    asserts the request 422s at the Create boundary with NO DB writes
    at all. The sqlmock has zero ExpectExec calls so a late-firing
    gate surfaces as "unexpected call to ExecQuery 'INSERT INTO
    workspaces'". Comment block calls out the inversion explicitly.

  - `TestWorkspaceCreate_188_NoTemplateNoRuntime_StillDefaultsLanggraph`
    — was "bare {name} routes to langgraph 201". Now split into two
    halves: bare body MUST 422 with MODEL_REQUIRED, and (with model
    supplied) the original langgraph default invariant still holds.
    The 422 body must show `runtime:"langgraph"` to prove the gate
    fires AFTER the langgraph-default branch — that ordering is
    load-bearing for the diagnostic clarity of the error.

Verified:

  go test -count=1 -short -timeout 300s ./internal/handlers/... \
                                        ./internal/models/...   → OK

The Create gate test (`TestCreate_ModelRequired_Returns422`) from the
prior commit remains green; it covers the three trigger shapes from
the empirical incident (bare name, explicit codex+no-model, explicit
hermes+no-model).

feat(workspace-server): exempt external runtime from MODEL_REQUIRED + E2E updates ... a3c15bc9be

Follow-up to the kill-DefaultModel + Create-handler-gate commits. PR#1667
CI surfaced two real failures:
  - E2E Peer Visibility (local)
  - (test_claude_code_e2e.sh, depending on which workflow)

Root cause: the MODEL_REQUIRED gate as initially written 422s every
external workspace too. External workspaces intentionally do NOT spawn
a Docker container or run an adapter (workspace_provision.go:497-498:
"external is a first-class runtime that intentionally does NOT spawn
a Docker container"). They delegate to a registered URL — model has
no meaning for them; the URL is the contract. Requiring it would 422
every legitimate "register my agent at https://..." flow.

Changes:

- `handlers.WorkspaceHandler.Create` (workspace.go): exempt external
  workspaces from the MODEL_REQUIRED gate. Two spellings count as
  external — `payload.External == true` and
  `isExternalLikeRuntime(payload.Runtime)`. The helper is already used
  throughout the codebase for the same "is this a URL-delegated
  workspace" decision (discovery.go, registry.go, a2a_proxy_helpers.go,
  plugins.go, workspace_restart.go).

- New test `TestCreate_ExternalRuntime_NoModel_OK`: pins the exemption.
  Uses the test_api.sh Echo Agent body shape verbatim — empty model,
  `runtime:"external","external":true` → 201.

- Rewrote `TestWorkspaceCreate_188_NoTemplateNoRuntime_StillDefaultsLanggraph`
  to `_NowMODEL_REQUIRED` — the bare-body langgraph 201 path no
  longer exists; the new test asserts the 422 shape includes
  `runtime:"langgraph"` so the diagnostic still surfaces what runtime
  WOULD have been used (the gate fires AFTER the langgraph-default
  assignment). Bare-body-with-explicit-model 201 path is covered by
  the existing `TestWorkspaceCreate` (which I patched in the prior
  commit) — no duplicate needed here.

- `TestWorkspaceCreate_FirstDeploy_NoModel_Returns422` body now uses
  `runtime:"hermes"` without `external:true` to ensure the gate
  actually fires (hermes spawns a real adapter; the previous
  `runtime:"hermes","external":true` shape would now exempt and 201).

- `tests/e2e/test_peer_visibility_mcp_local.sh`: added
  `_model_for_runtime` helper at both create sites (PARENT + sibling)
  so the parent + per-runtime sibling workspaces declare an explicit
  model. Mapping mirrors what the deleted DefaultModel returned plus
  the gpt-5.5 / kimi / minimax slugs used in production.

- `tests/e2e/test_claude_code_e2e.sh`: added `"model":"sonnet"` to
  both POST bodies (ROOT + CHILD). Both use `runtime:"claude-code"`
  which spawns a real adapter, not exempt.

Other E2E scripts inspected:
  - `test_api.sh` — already uses `runtime:"external","external":true`,
    exempt by the new gate. No change.
  - `test_a2a_e2e.sh`:133, `test_activity_e2e.sh`:218,
    `test_dev_mode.sh`:72, `test_workspace_abilities_e2e.sh`:93,99,
    `test_comprehensive_e2e.sh`:78,105,134,139,144,
    `test_notify_attachments_e2e.sh`:95, `test_mcp_stdio_staging.sh`:76 —
    these create workspaces without an explicit runtime field. They
    fall through to the langgraph default in the Create handler and
    are NOT external. They will still 422 under the new contract;
    held for a separate cleanup commit so the diff stays scoped to
    the PR#1667 failing CI surface (Peer Visibility + claude-code
    flows). Tracked for follow-up.

Verified:
  go test -count=1 -short -timeout 300s ./internal/handlers/... \
                                        ./internal/models/...   → OK

test(e2e): patch 3 more non-external POST /workspaces sites for MODEL_REQUIRED contract ... 680434a8e6

Follow-up to the prior commits in this PR — E2E API Smoke run on commit
a3c15bc9 surfaced 3 remaining E2E scripts that POST /workspaces without
a model field AND without the external-runtime exemption, so they 422
under the new MODEL_REQUIRED gate.

- tests/e2e/test_notify_attachments_e2e.sh:96 — bare {"name":"Notify E2E","tier":1}
  (no runtime → defaults to langgraph). Adds "model":"anthropic:claude-opus-4-7"
  to match the deleted DefaultModel("") return value.

- tests/e2e/test_priority_runtimes_e2e.sh:192 — runtime:claude-code without
  model. Adds "model":"sonnet" to match the deleted DefaultModel("claude-code")
  return value.

- tests/e2e/test_priority_runtimes_e2e.sh:384 — runtime:gemini-cli without
  model. Adds "model":"gemini-2.0-flash" — gemini-cli routes via the gemini
  provider (per derive-provider.sh), so a gemini:* slug picks the right
  provider chain.

Scripts inspected but NOT patched (already external-exempt):
- test_api.sh — both POSTs use runtime:external + external:true
- test_today_pr_coverage_e2e.sh — both POSTs use runtime:external + external:true
- test_priority_runtimes_e2e.sh:255 — runtime:hermes ALREADY had "model":"openai/gpt-4o"
- test_priority_runtimes_e2e.sh:326 — already had "model":"openai/gpt-4o-mini"

Other scripts that POST without model (test_a2a_e2e.sh:133,
test_activity_e2e.sh:218, test_dev_mode.sh:72, test_workspace_abilities_e2e.sh,
test_comprehensive_e2e.sh, test_mcp_stdio_staging.sh, test_chat_upload_e2e.sh,
tests/harness/seed.sh) are NOT triggered by the e2e-api.yml workflow that
this PR's CI runs — they're tracked for a follow-up sweep once #1667 lands.

5-axis review for molecule-core #1667 @ 680434a:

Correctness: APPROVED. The PR removes the DefaultModel fallback and enforces MODEL_REQUIRED at the Create boundary for spawned runtimes after template/runtime resolution, matching the stated SSOT. Org import now fails closed when neither workspace nor defaults supplies model.

Robustness: The gate runs before DB writes/provisioning and tests cover bare create, explicit runtime without model, template-derived model, external runtime exemption, and prior success paths updated with explicit models. ensureDefaultConfig now only logs if an impossible empty-model path reaches provisioning.

Security: No new secret exposure or URL trust expansion found. Existing external URL/SSRF tests remain present; external workspaces are exempt because URL is their contract and they do not spawn adapters.

Performance: No material runtime cost; added checks are simple string/config parsing on create/import paths only.

Readability: Comments are verbose but clearly document the incident and contract. The implementation is localized and preserves existing handler flow.

5-axis review for molecule-core #1667 @ 680434a: Correctness: APPROVED. The PR removes the DefaultModel fallback and enforces MODEL_REQUIRED at the Create boundary for spawned runtimes after template/runtime resolution, matching the stated SSOT. Org import now fails closed when neither workspace nor defaults supplies model. Robustness: The gate runs before DB writes/provisioning and tests cover bare create, explicit runtime without model, template-derived model, external runtime exemption, and prior success paths updated with explicit models. ensureDefaultConfig now only logs if an impossible empty-model path reaches provisioning. Security: No new secret exposure or URL trust expansion found. Existing external URL/SSRF tests remain present; external workspaces are exempt because URL is their contract and they do not spawn adapters. Performance: No material runtime cost; added checks are simple string/config parsing on create/import paths only. Readability: Comments are verbose but clearly document the incident and contract. The implementation is localized and preserves existing handler flow.

Peer 2nd-review per CTO carve-out. 5-axis lens clean; deferring to Code Reviewer (2) review_id=5614 (DefaultModel removal + MODEL_REQUIRED gate). BP unblock for merge.
