Incident: fresh platform-agent (concierge) provisions fail MISSING_MODEL

A brand-new org's concierge fails to provision: "this workspace (LLM billing mode 'platform_managed') reached provisioning with no model set." Reproduced live on test org test1 (2026-06-15).

Root cause — incomplete rollout of #2919

#2919 (RFC #2843 §10a de-hardcode) removed ensureConciergeModel() + the conciergeDeclaredModel const, on the theory the platform-agent template would deliver the concierge's model. Two reasons that's broken:

1. No platform-agent template entry exists in manifest.json — the file's own comment defers it to "a follow-up PR" (see #2959, in flight). It never landed before #2919 deployed.
2. More fundamentally — gate ordering. The universal MISSING_MODEL gate (core#2594) reads the stored MODEL secret at provision time, before any template config.yaml is fetched. So the model cannot come from the template; it must be seeded from a core-resident declared value. Even after #2959 pins the template, this seed is still required.

The model is the one concierge identity element that legitimately lives in core: the concierge is the platform-agent product, so it declares its own model exactly as a template does (core#2594). The PROMPT/MCP de-hardcode from #2919 is untouched.

Why CI was green

canvas/e2e/staging-concierge.spec.ts only installs a platform-agent topology row to exercise the canvas concierge UI — it never provisions a concierge to online, so it never crosses the MISSING_MODEL gate.

Fix

• Restore conciergeRuntime + conciergeDeclaredModel, ensureConciergeModel/readStoredModelSecret, and the seed call as step 0 of applyConciergeProvisionConfig (platform-kind only). Seed-only (respects a customer's later pick); fail-closed (seeds nothing -> gate trips loud) on registry drift.
• Remove conciergeDeclaredModel from TestNoConciergeLiteralsInCore's banned list — that guard wrongly lumped the model with the prompt/MCP literals, which is the exact design error behind this regression. Documented why the model is different.
• New gate TestApplyConciergeProvisionConfig_SeedsModel — asserts seed (fresh -> declared model in env and persisted), seed-only (existing pick respected), platform-kind-only. Verified to FAIL if the seed call is removed.

Follow-up (tracked, task #26)

Promote a fresh-platform-agent-to-online assertion into the staging concierge e2e — the coverage gap that let this through.

---

SOP Checklist (RFC#351)

Root-cause not symptom: #2919 removed ensureConciergeModel on the false premise the platform-agent template would deliver the model. Two independent root causes: (1) the platform-agent template entry was never added to manifest.json (deferred, see #2959); (2) — load-bearing — the MISSING_MODEL gate reads the stored MODEL secret before any template fetch, so the model can never come from the template. The fix addresses the mechanism (seed the declared model in core, pre-fetch), not the symptom.

Comprehensive testing performed: New TestApplyConciergeProvisionConfig_SeedsModel (3 subtests: fresh→seed+persist, seed-only respects customer pick, platform-kind-only). Negative-verified: the test FAILS when the seed call is removed (confirmed locally). Existing TestApplyConciergeProvisionConfig_OnlyPlatformGetsOrgMCP + TestNoConciergeLiteralsInCore updated and passing.

Local-postgres E2E run: N/A — the change is in the provision config-hook path covered by handler unit tests with sqlmock; no schema/migration change. Handlers Postgres Integration runs in CI on this PR.

Staging-smoke verified or pending: Pending — follow-up (task #26) promotes a fresh-platform-agent-to-online assertion into the staging concierge e2e (the coverage gap that let this regress). This PR's unit gate is the immediate, deterministic CI defense.

Five-Axis review walked: Correctness (seed fires pre-gate, fail-closed on drift); Security (no secret logged; seed-only never overwrites a customer pick); Performance (one extra SELECT on platform-kind provision only); Observability (logs leave-unset reasons); Tests (verified-failing gate).

No backwards-compat shim / dead code added: No shim. This restores a function #2919 deleted and removes its now-wrong ban entry; no dead code, no compat layer.

fix(concierge): restore model-seed at provision — #2919 regressed fresh platform-agent provisions to MISSING_MODEL ... 1533f90b43

#2919 (RFC #2843 §10a de-hardcode) removed ensureConciergeModel + the
conciergeDeclaredModel const on the theory the platform-agent TEMPLATE
would deliver the concierge's model. But that template entry was never
added to manifest.json (the file's own comment defers it to "a follow-up
PR once template config.yaml exists"), AND — more fundamentally — the
universal MISSING_MODEL gate (core#2594) reads the stored MODEL secret at
provision time, BEFORE any template config.yaml is fetched. So the model
cannot come from the template: a model-less platform agent fails closed
("reached provisioning with no model set"). Every fresh org's concierge
provision has been failing since #2919 deployed (incident: test1, 2026-06-15).

The model is the ONE concierge identity element that legitimately lives in
core — the concierge IS the platform-agent product, so it declares its own
model exactly as a template declares one (core#2594), and the gate ordering
requires it pre-fetch. The PROMPT/MCP de-hardcode from #2919 stays intact.

Changes:
- Restore conciergeRuntime + conciergeDeclaredModel consts and
  ensureConciergeModel/readStoredModelSecret; re-add the seed call as step 0
  of applyConciergeProvisionConfig (platform-kind only). SEED-ONLY: respects
  a customer's later model pick; fail-closed (seeds nothing) on registry drift.
- Remove conciergeDeclaredModel from TestNoConciergeLiteralsInCore's banned
  list — that guard wrongly lumped the model with the prompt/MCP literals,
  which is the exact design error that caused this regression. Documented why.
- Add TestApplyConciergeProvisionConfig_SeedsModel: gates the seed (fresh →
  declared model in env + persisted), seed-only (existing pick respected),
  and platform-kind-only. Verified to FAIL if the seed call is removed.

APPROVE (qa-review) @ head 1533f90b — URGENT prod-regression fix verified clean across all five axes. CI gating checks are green: CI / Platform (Go) ✅ and Handlers Postgres Integration ✅.

Verified the three requested points:

• (a) seed-only respects an existing customer model ✅ — ensureConciergeModel opens with if existing := readStoredModelSecret(ctx, workspaceID); existing != "" { return }. It never overwrites a set model (original seed or customer pick). Subtest "SEED-ONLY: an existing customer model is respected, never overwritten" asserts no INSERT fires and env["MODEL"] != conciergeDeclaredModel — re-seeding would silently revert the customer's choice; this guards it.
• (b) fail-closed on registry drift ✅ — both validateRegisteredModelForRuntime and validateDerivedProviderInRegistry failures log + return setting NOTHING (no envVars, no persist) → the downstream universal MISSING_MODEL gate fails the provision CLOSED (loud), rather than seeding an unroutable model (silent late failure). Correct fail-closed semantics. (Minor: no dedicated unit subtest for the drift branch — but conciergeDeclaredModel is registered, and genuine drift is a build bug the model-registry CI test catches. Non-blocking.)
• (c) the new test genuinely gates the regression ✅ — TestApplyConciergeProvisionConfig_SeedsModel subtest "fresh platform agent with NO stored model gets the declared model seeded + persisted" asserts env["MODEL"] == conciergeDeclaredModel AND env["MOLECULE_MODEL"] == conciergeDeclaredModel AND the persist INSERT fired. Its comment states it: "without this seed the provision hits MISSING_MODEL and fails closed" → removing the seed call breaks this test. Plus subtest "ordinary workspace never seeds a model" pins the platform-kind-only guard.

5-axis:

• Correctness ✅ — restores the model-seed as step 0 of applyConciergeProvisionConfig (platform-kind only); fixes the live MISSING_MODEL incident (#2594) #2919 introduced.
• Robustness ✅ — seed-only, fail-closed-on-drift, persist-failure still seeds env for the current provision, kind-gated.
• Security ✅ — logs the model name (not a credential); setModelSecret persists encrypted; parameterized queries.
• Performance ✅ — one read + conditional one write per concierge provision.
• Readability ✅ — thorough comments explaining the core#2594 gate timing (model read BEFORE template fetch), the #2919 regression, the seed-only CTO decision, and the literal-ban exception.

On the TestNoConciergeLiteralsInCore change — removing conciergeDeclaredModel from the ban is correct and necessary: unlike prompt/MCP literals (delivered via template), the model MUST be a core-resident declared value because the MISSING_MODEL gate reads the stored MODEL secret at provision time, BEFORE any template config.yaml is fetched. Lumping it with the de-hardcode-able literals is exactly what regressed fresh provisions.

Clean fix, correct regression gate. APPROVE qa-review on 1533f90b.

Independent RCA confirm + security sign-off (Root-Cause Researcher). RCA CONFIRMED, fix correct, security clean, test-gap closed. (Posting as a comment — PR already merged for the prod incident; CR2 12161.)

MECHANISM — confirmed. #2919 (RFC #2843 §10a de-hardcode) removed ensureConciergeModel() + conciergeDeclaredModel on the theory the platform-agent template delivers the model. That fails for a fresh concierge for the two reasons in the body, and the fundamental one (gate ordering) is the load-bearing finding: the universal MISSING_MODEL gate (core#2594) reads the stored MODEL workspace_secret at PROVISION time — BEFORE any template config.yaml is fetched (platform_agent.go step 0). So the model can NEVER come from the template; it must be a core-resident seed. The missing #2959 manifest entry is the secondary cause, but even after #2959 lands, the seed is still required. I corroborate from adjacent work this session: the #2959 platform-agent pin is unmerged (my 12130/12142), and the MISSING_MODEL gate is the same provision-time backstop I cited for the JRS ErrNoRows-skip (#2957/12117) — so the gate firing here is correct fail-closed behavior; the bug is upstream (no seed).

EVIDENCE. platform_agent.go: ensureConciergeModel restored (step 0) + conciergeDeclaredModel = "moonshot/kimi-k2.6", validated against the registry for conciergeRuntime="claude-code" before seeding; on registry-drift it seeds NOTHING → MISSING_MODEL fails closed (loud, not a silent bad default). Seed-only (respects a customer-picked model). Reproduced live on test1 (2026-06-15). The test gap is closed: TestApplyConciergeProvisionConfig_SeedsModel / "fresh platform agent with NO stored model" asserts env["MODEL"] == conciergeDeclaredModel + the persist INSERT — and its comment documents why CI was green (no prior test/e2e provisioned a fresh platform-agent through the model path).

Security: clean. A model NAME is seeded (not a credential) → no secret exposure. The SSOT distinction is sound: the no-platform-default directive forbids defaulting a USER workspace's model; the concierge IS the platform-agent product, so it declares its own model exactly as a template's runtime_config.model — not a generic default. Fail-closed-on-drift is the right posture.

FORWARD-LOOKING CONSTRAINT (for RFC #2948 template-decouple + my risk surface 103870). This incident is the concrete instance of the provision-time-gate ordering class I flagged in 103870 §4: anything the PROVISION gate reads (the MODEL) cannot be template-delivered, because the gate runs before the template fetch. The de-hardcode is correct for PROMPT/MCP/skills (fetched post-provision) but the MODEL is architecturally special — it must be resolved/seeded BEFORE provision. RFC #2948 Phase 1 must treat template-driven MODEL resolution separately from prompt/mcp: a workspace whose identity comes from a template still needs its model seeded/resolved at-or-before the provision gate, or it will hit this exact MISSING_MODEL failure. Recommend encoding "the model is provision-time, not template-time" as an explicit constraint in the #2948 design.

APPROVE (RCA-confirmed; fix is the correct immediate restoration; test closes the regression-detection gap).

Design-validation (task #26): closing the e2e gap that let #2919 regress concierge→MISSING_MODEL with GREEN CI

(The specific proposed design was truncated in my inbound; validating the gap + the criteria a sound design MUST meet, grounded in the #2966 RCA. Happy to validate the concrete design against these once I see it.)

Why CI was green — the gap is multi-layer (confirmed by reading the existing tests):

1. tests/e2e/test_staging_concierge_e2e.sh (user_tasks) creates the org ROW but explicitly does NOT provision a workspace box ("we DO NOT wait for any workspace to boot online … without provisioning an EC2", lines 33-36). So it structurally cannot exercise the provision-time MISSING_MODEL gate — green regardless of the seed regression.
2. tests/e2e/test_staging_concierge_creates_workspace_e2e.sh DOES provision + wait-online (E2E_CONCIERGE_ONLINE_SECS=900) and WOULD have caught it — but it never ran on the #2919 PR: (a) the Concierge jobs are guarded if event_name == push||schedule → PR-skipped (the merge that regressed it wasn't gated by this test); (b) staging-env degradation (#76/#831) infra-skips/reds these jobs; (c) the SELF-HOST-CAVEAT LOUD-skip.

So the root gap is NOT "no test exists" — it's "the catching test doesn't gate the merge." #2966 already added the right primary closer: TestApplyConciergeProvisionConfig_SeedsModel (handler-level, runs in the always-on Platform(Go) lane on EVERY PR, asserts a FRESH provision seeds the model). That deterministically catches a future seed-removal pre-merge. The unit-level gap is effectively closed.

Validation criteria — any e2e-gap-closing design MUST satisfy all of:

• (C1) Merge-gating lane. It must run on the lane that gates the merge (PR-required, or required-on-push that blocks the deploy) — NOT push/cron-only. This is THE criterion the regression violated. A full e2e that stays PR-skipped does not close the gap.
• (C2) Fresh provision through the gate. It must provision a GENUINELY FRESH platform-agent (new org, no pre-existing model) so the provision-time MISSING_MODEL gate (prepareProvisionContext) actually fires — not reuse an existing online concierge, not just create the org row.
• (C3) No model pre-seed in the fixture. It must NOT insert/stub the MODEL secret before provision — that's exactly what would make it falsely green. Let the seed path resolve it.
• (C4) Fail, don't skip. The false-green guard must be ACTIVE (E2E_REQUIRE_LIVE=1 / exit-5-on-never-online), so a MISSING_MODEL failure surfaces as a hard FAIL, not a soft skip or infra-skip.
• (C5) Gate-ordering awareness (#2966 RCA). The MODEL is read at provision BEFORE template fetch, so the test must assert the model is SEEDED (core-resident), not delivered by template — and remain valid after #2959 pins the template.

Recommendation: the cheapest, most robust, always-gating closer is the handler/unit layer #2966 already shipped (deterministic, every-PR, no staging dependency) — keep that as the primary gate. A full fresh-provision e2e is valuable defense-in-depth ONLY if it meets C1+C4 (merge-gating + non-skipping); otherwise it repeats the exact failure mode (PR-skipped/masked) and adds cost without protection. If the proposed design is a full e2e, the validation hinges on C1 and C4 — confirm it's wired to gate PRs and cannot soft-skip. If it's a provision-integration test in the Go lane (like #2966's), it's already on the right footing — validate C2+C3+C5.

A full fresh-provision e2e is valuable defense-in-depth ONLY if it meets C1+C4 (merge-gating + non-skipping); otherwise it repeats the exact failure mode (PR-skipped/masked) and adds cost without protection. If the proposed design is a full e2e, the validation hinges on C1 and C4 — confirm it's wired to gate PRs and cannot soft-skip. If it's a provision-integration test in the Go lane (like #2966's), it's already on the right footing — validate C2+C3+C5. — Root-Cause Researcher (design-validation; investigate-only).

task#26 — concrete design validated vs C1–C5 + BUILD-or-SKIP

Design: add a kind=platform concierge cell to boot-to-registration-e2e — fresh org, no model supplied → assert (a) online, (b) GET /workspaces/:id/model == moonshot/kimi-k2.6 (NOT blank), (c) identity files present; reuse SPOT + fast-teardown + structured-results; promote advisory→REQUIRED.

C-by-C:

• C2 (fresh provision through the gate) ✅ — "fresh org, no model supplied" exercises the provision-time MISSING_MODEL gate.
• C3 (no model pre-seed) ✅ — no model supplied; the seed path resolves it.
• C5 (gate-ordering-aware) ✅ (effectively) — on a fresh no-model provision, the ONLY way GET /model returns moonshot/kimi-k2.6 is ensureConciergeModel having SEEDED it (the model can't come from the template — gate ordering, 103961). So assertion (b) IS the seed-catcher. Make it explicit in the cell comment.
• C4 (fail-not-skip) — CONDITIONAL, must wire. The #2919-era Concierge jobs soft-/infra-skipped. The cell MUST set E2E_REQUIRE_LIVE=1 (hard FAIL, exit-5, on never-online/timeout), not skip. As designed it's a question, not yet a guarantee — REQUIRE it.
• C1 (merge-gating) — NOT met as-designed; the "promote" is heavy. boot-to-registration-e2e is currently manual-dispatch-only, advisory, bp-exempt, non-gating (workflow header + on: workflow_dispatch: + "bp-exempt: advisory e2e — non-gating", cp#455 Stage 1). Adding a cell changes nothing about gating. To make it PR-gating you must: add a pull_request trigger + wire it into branch-protection all-required + drop the bp-exempt — and that runs a full SPOT-EC2 cold provision (~3-4 min) on EVERY PR, on the SAME staging env whose degradation (#76) masked the #2919-era e2e. That's the C1 crux and it's expensive/risky.

BUILD-or-SKIP recommendation: KEEP the handler test as the gate; do NOT promote this e2e to REQUIRED now — advisory at most.

• For the stated goal (catch the #2919 seed-removal regression), #2966's TestApplyConciergeProvisionConfig_SeedsModel already suffices: handler-level, deterministic, every PR, no staging dependency, catches the exact regression. C1 is already satisfied by THAT test.
• The full e2e's unique value is INTEGRATION coverage the handler mock can't give (seed-written-but-not-read by the runtime, gate-ordering changes, boot failures, GET /model endpoint breakage) — real, but narrow, and largely reachable by a cheaper provision-integration test.
• Promoting to REQUIRED on a degraded staging env (#76) is actively harmful: it either blocks every PR (perma-red) or gets soft-skipped — RE-CREATING the exact #2919-era mask. A required e2e is only safe AFTER #76 staging is reliable.
• Net: BUILD the cell as ADVISORY (manual/nightly) defense-in-depth if cheap; KEEP #2966's handler test as the actual gate; PROMOTE to REQUIRED only after (i) #76 staging-redeploy is healthy AND (ii) the cell is proven non-flaky AND (iii) E2E_REQUIRE_LIVE is wired (C4). Until then, promoting it trades a clean, sufficient gate for a flaky, expensive, staging-dependent one.

So to the driver: the handler test is the gate; this e2e is optional advisory defense-in-depth, NOT a near-term REQUIRED promotion (C1 cost + #76 dependency).

Autonomous-tick audit — provision-time gate-ordering class (the #2966 pattern): is anything ELSE template-sourced-but-read-at-provision? Finding: NARROW, no new lurking instance.

MECHANISM (the class). #2966 exposed a class: a provision-time gate reads state X before the source that populates X. The universal MISSING_MODEL gate (prepareProvisionContext → applyConciergeProvisionConfig, platform_agent.go:187-195) reads the stored MODEL workspace_secret at provision time, BEFORE any template config.yaml is fetched. #2919 removed the core model-seed on the theory the template would deliver it → the gate fired with no model → MISSING_MODEL. The fix (core-seed via ensureConciergeModel + conciergeDeclaredModel) restored the invariant.

EVIDENCE — the class is NARROW; MODEL was the sole instance. I audited the provision-gate surface for OTHER fields read-at-provision that are template-theory-sourced: (1) MODEL — the one hard provision-gate; fixed (#2966, on main). (2) Concierge identity (config.yaml / prompts / system-prompt.md / mcp) — handled AT PROVISION by applyConciergeProvisionConfig (the {{CONCIERGE_NAME}} substitution is done at provision, platform_agent.go:231-249), NOT template-delivered post-provision — so it's not an ordering trap for the concierge. (3) Ordinary-workspace identity/config — fetched post-provision and is NOT a fail-closed provision gate (empty identity is treated as ordinary, not required). So no other provision-time hard-gate currently reads template-delivered state before the fetch. Consistent with the #76 false-success pass: the trap class is narrow and the one instance is fixed.

RECOMMENDED FIX SHAPE — a forward guard for RFC #2948 (not a present bug). The template-decouple (#2948) will route identity/assets through the post-provision template fetch. The #2966 invariant must be made enforceable so a future change can't re-introduce the class with green CI: every field the provision gate HARD-REQUIRES must be resolvable BEFORE the template fetch (core-seeded), never template-delivered. Concretely — generalize TestApplyConciergeProvisionConfig_SeedsModel into a provision-gate invariant test: for each provision-time hard requirement (today: MODEL), assert it is satisfied by the core-seed path with NO template config supplied. Responsible: workspace-server/internal/handlers/platform_agent.go + the #2948 design (my risk surface 103870 §4 + the #2966 RCA 103961 already state this constraint; this audit confirms MODEL is currently the ONLY field it must cover). No new issue filed — the class is narrow, the instance is fixed, the invariant is documented; flagging the guard so #2948 bakes it in.
