test(e2e): add google-adk arm to priority-runtimes e2e (registration + BYOK)

google-adk (a shipped runtime; providers.yaml runtimes block, registered cp#568 / core#2327) had ZERO serving/runtime e2e (core#2332 P0.1). Add a google-adk arm to the priority-runtimes e2e with a two-part contract: 1. REGISTRATION (always, no live creds): assert google-adk is present in the deployed manifest.json workspace_templates — the SSOT the Create-handler's runtime allowlist is derived from (runtime_registry.go::loadRuntimesFromManifest). Absence would 422 RUNTIME_UNSUPPORTED, so this is the precondition for any serving and is now gated even on a key-less CI run. (Does not bump VALIDATED.) 2. LIVE arm (REQUIRED-when-keyed, LOUD-skip-when-absent): with E2E_GOOGLE_API_KEY set, provision the AI-Studio BYOK path (bare gemini-2.5-pro + GOOGLE/GEMINI key) end-to-end (online + non-error A2A). A miss is a HARD fail() (fail-closed-if-present) — same idiom as the claude-code/hermes/openai arms, NOT a best-effort/fail-open arm. Without the key the live portion is a LOUD skip(). The keyless-Vertex PROD path needs a platform WIF identity CI lacks, so it is deliberately NOT driven (no fail-open arm). Wired into the E2E_RUNTIMES dispatcher, `all`, the default WANT set, and the header/usage docs. bash -n + shellcheck clean (no new findings vs origin/main); test_require_live_priority_gate_unit.sh still 7/7 green.

+# Bug (fixed in fix/sop-tier-authz-no-org-fallback):
+#   sop-tier-check.sh probed team membership at /teams/{id}/members/{user}.
+#   If EVERY team probe failed (e.g. 403 — token lacks read:organization, or
+#   any visibility/flakiness gap), it FELL BACK to /orgs/{org}/members/{user}
+#   and credited that org member as a member of EVERY queried team. The
+#   evaluator then treated those synthetic memberships as real, so a plain
+#   NON-CEO org member satisfied tier:high (ceo). A visibility/auth gap became
+#   a real highest-tier authorization PASS — privilege escalation.
+#
+# Fix (fail-closed authorization):
+#   - The org-member ⇒ "member of all teams" fallback is REMOVED. Org
+#     membership is never credited as team membership.
+#   - A team probe that returns anything other than 200/204 (member) or 404

+/**
+ * Staging canvas E2E — REAL desktop take-control path (core#2261 "Gap 1").
+ *
+ * This is the live-e2e gate that the existing staging-tabs.spec.ts does NOT
+ * provide. staging-tabs only opens the 13 declared workspace-panel tabs
+ * (TAB_IDS at staging-tabs.spec.ts:24-38 — `display` is NOT among them) and
+ * asserts they render without a "Failed to load" toast. It never acquires
+ * display control, never opens the noVNC WebSocket, and never asserts a
+ * framebuffer frame arrives. The companion unit test
+ * canvas/src/components/tabs/__tests__/DisplayTab.test.tsx mocks the RFB
+ * constructor (vi.mock("@novnc/novnc"), see its lines 8/20-39) so NO real
+ * WebSocket is ever opened there either. Result: a broken take-control path
+ * (acquire → noVNC WS upgrade → ws-proxy → EIC → websockify → x11vnc → Xvfb)
+ * ships GREEN. This spec closes that gap by exercising the REAL wire path
+ * end to end against a live, desktop-capable staging workspace.
+ *
+ * What it asserts (the real path, no mocks):
+ *   1. POST /workspaces/<id>/display/control/acquire returns 200 with a
+ *      session_url that carries the signed token in its `#token=` fragment
+ *      (mirrors workspace_display_control.go:signedDisplaySessionURL).
+ *   2. Opening the noVNC WebSocket at session_url with the subprotocols
+ *      ["binary", "molecule-display-token.<token>"] (exactly what the canvas
+ *      sends — DisplayTab.tsx:339) UPGRADES (onopen fires, readyState===OPEN,
+ *      no immediate 1006 abnormal close). A 1006 / 403 means the handshake
+ *      failed somewhere in the proxy chain.
+ *   3. At least one BINARY framebuffer message arrives on that socket — a
+ *      real frame off x11vnc, not just a panel mount. RFB sends a
+ *      ProtocolVersion banner ("RFB 003.00x\n") as the first server message,
+ *      which proves the upstream VNC server is live behind the EIC tunnel.
+ *
+ * Auth model (important): the WS upgrade is gated by workspace-server
+ * middleware.AdminAuth. A browser WebSocket CANNOT set an Authorization
+ * header, so in production the canvas WS upgrade passes AdminAuth via the
+ * same-origin-canvas path (wsauth_middleware.go:isSameOriginCanvas, which
+ * keys off the Origin header the browser sets automatically on a same-origin
+ * WS upgrade). We therefore open the socket from inside the browser page via
+ * page.evaluate AFTER navigating to the tenant origin — so the browser sends
+ * `Origin: https://<slug>.staging.moleculesai.app`, exactly as production
+ * does. The acquire POST (which CAN carry a header) uses the per-tenant admin
+ * bearer set on the context. This is the faithful production handshake, not a
+ * synthetic one.
+ *
+ * Gate / cost: this test only runs when STAGING_DISPLAY_WORKSPACE_ID points
+ * at a STANDING desktop-capable workspace (compute.display.mode ==
+ * "desktop-control"). We deliberately do NOT provision one in the shared
+ * staging-setup.ts: a desktop AMI boots in ~12-15 min and would tax the
+ * existing tabs harness on every run. Standing that workspace up is a cost
+ * item for the CTO (one always-on desktop EC2 on staging). Until that exists,
+ * the test SKIPS loud. When the env IS present, any failure in
+ * provision/acquire/upgrade is a HARD error — fail-closed, never silently
+ * green (no "flaky" disposition: a 1006 names a broken proxy hop).

+ * PROMOTION-READINESS — staging canvas E2E → HARD merge-gate
+ * ----------------------------------------------------------
+ * NOW RELIABLE (deterministic; these no longer flap on timing):
+ *   - Every wait is condition-based (toBeVisible / toHaveAttribute /
+ *     expect.poll). There is NO fixed waitForTimeout / sleep in the spec;
+ *     the only setTimeout is the bounded poll-interval inside
+ *     staging-setup.ts waitFor(), which has a hard deadline.
+ *   - Tabs are asserted on REAL settled content (non-empty, non-spinner),
+ *     not just "container is visible" — an empty or stuck-loading panel now
+ *     fails instead of shipping green.
+ *   - The ErrorBoundary ("Something went wrong") is asserted absent at app
+ *     hydration AND per tab — a React subtree crash can no longer pass.
+ *   - Visible error alerts inside a panel fail non-degraded tabs (was a
+ *     weak [role=alert]:has-text("Failed to load")-only check that missed
+ *     both other error phrasings and role-less error divs).
+ *   - The driven tab list is parity-checked against the live DOM, so a new
+ *     SidePanel tab can't ship un-tested and a removed one fails loud.
+ *   - Click→activation is confirmed (aria-selected) before asserting the
+ *     panel, removing a wrong-panel race.
+ *   - The suite is fail-closed: CANVAS_E2E_STAGING=1 with no tenant state
+ *     hard-errors (never skips→green); CANVAS_E2E_STAGING unset cleanly
+ *     skips (operator did not request staging).
+ *
+ * STILL BLOCKS PROMOTION-TO-REQUIRED (do NOT flip continue-on-error here —
+ * CTO-owned, RFC internal#219 §1):
+ *   - INFRA DEPENDENCY: each run provisions a real staging EC2 tenant
+ *     (12-20 min cold boot). Required-gate latency + AWS/Cloudflare/CP
+ *     availability become merge-blockers. A staging outage would freeze
+ *     main even though the code is fine — unacceptable for a required check
+ *     until staging has an SLA or this runs against a warm pre-provisioned
+ *     pool.
+ *   - SHARED-RESOURCE FLAKE SURFACE: TLS/DNS/ACME propagation on a shared
+ *     staging zone (staging-setup TLS_TIMEOUT_MS) is outside this repo's
+ *     control. Deterministic here ≠ deterministic upstream.
+ *   - SECRET DEPENDENCY: CP_STAGING_ADMIN_API_TOKEN must be present on the
+ *     runner. The workflow's skip-if-absent (core#2225) keeps a missing
+ *     secret from painting red — correct for non-gating, but a REQUIRED
+ *     check must instead guarantee the secret is always present, else it
+ *     skip-greens the very thing it is supposed to enforce.
+ *   - SINGLE-WORKSPACE COVERAGE: one hermes/platform_managed workspace that
+ *     does NOT boot an agent on staging (no CP LLM proxy env, workspace-
+ *     server #2162). Tabs render, but agent-dependent content paths (live
+ *     chat round-trip, traces from a real run) are not exercised.
+ *
+ * PROMOTION CHECKLIST (when CTO signs off on making this required):
+ *   1. Warm pre-provisioned tenant pool OR a staging SLA bounding boot time.
+ *   2. Guarantee CP_STAGING_ADMIN_API_TOKEN on the gating runner; turn the
+ *      skip-if-absent into a hard error for the required path.

 # Admin Authentication Runbook

+## Auth is fail-CLOSED in every environment — `ADMIN_TOKEN` is the bootstrap credential
+
+Per the CTO "nothing should be fail-open" directive, **every** auth path on the
+workspace-server fails closed — there is no dev-mode / zero-token / DB-outage
+hatch that grants access. This includes:
+
+- `AdminAuth` and `WorkspaceAuth` (admin + per-workspace routes),
+- `CanvasOrBearer` (the cosmetic `PUT /canvas/viewport` route), and
+- `validateDiscoveryCaller` (`/registry/:id/peers`, `/registry/discover/:id`).
+
+Consequence for **bootstrap**: a brand-new self-hosted / dev install has **no
+DB-backed tokens yet**, and there is no longer a fail-open that lets the first
+request through. The **only** way to reach admin routes (and to mint the first
+workspace token via `POST /admin/workspaces/:id/tokens`) is to set `ADMIN_TOKEN`
+in the platform environment and present it as the bearer. This is the "local
+mimics production" principle: there is no zero-config bootstrap.
+
+- **Local dev:** `scripts/dev-start.sh` provisions a deterministic
+  `ADMIN_TOKEN` into `.env` (and exports the matching `NEXT_PUBLIC_ADMIN_TOKEN`
+  so the canvas authenticates with it). See `docs/quickstart.md`.
+- **Self-hosted / SaaS:** set `ADMIN_TOKEN` to a strong random secret
+  (`openssl rand -base64 32`) in the platform env and bake the matching

+exit) and **fail closed** (treat inability-to-verify as **FAILURE**, never as a
+pass). An unverifiable check is a red check, full stop.
+
+This is the same family of bug as the no-flakes rule (§ *No flakes*): a green
+that isn't real. A flake is a green/red that flips for an unnamed reason; a
+fail-open gate is a green that was never earned. Both let unverified code reach
+`main`, and both are merge-blocking.
+
+### Applies to
+
+Required / hard gates on **protected contexts**: pushes to `main`, internal
+protected branches, and **same-repo** PRs (`pull_request_target`). On these
+contexts the *cause* of an unverifiable run is **irrelevant** — every one of the
+following MUST fail closed:
+
+- auth failure (401 / 403),
+- missing token or identity,
+- under-scoped credential,
+- unreachable dependency (network, Infisical, control-plane, registry),
+- a required test file that is absent or collects zero tests,
+- any transient error the check cannot prove was benign.
+
+"I couldn't check" is reported and scored exactly like "the check failed." A
+gate that can be silently defanged by removing a secret is not a gate.
+
+### The one allowed exception — explicit trust-boundary split
+
+Legitimate degradation is permitted **only** where the secret genuinely cannot
+exist — e.g. **fork PRs**, which by design have no access to repo secrets. Such
+degradation is allowed **only** when it is:
+
+1. gated behind an **explicit** fork / advisory branch in the workflow logic
+   (an intentional trust-boundary split, not an incidental `if: secrets...`),
+2. **clearly marked advisory** in its name and output, and
+3. **NOT counted as a passing REQUIRED context** — it may inform, it may not
+   satisfy the gate.
+
+Silent degradation that satisfies a required gate is **forbidden**. If a fork PR
+needs the real check, it must run via a maintainer-triggered same-repo path
+(where the secret exists and the check therefore fails closed), not by quietly
+passing the required context with no verification.
+
+### Auth-failure vs. genuine-absence — do not conflate
+
+Distinguish the two so a real finding is never masked and a masked finding is
+never mistaken for real:
+
+- **`403` (or 401) on a protected context → fail closed.** You could not verify;
+  that is a check failure, not a finding about the resource.
+- **A real `404` from a read made *with a valid, sufficiently-scoped token* →
+  the real finding.** The resource is genuinely absent; report it as such.
+
+A `403` reported as "resource not found" is itself a fail-open bug.
+
+### Required practice
+
+Every gate that depends on a token, an identity, or an external read MUST ship
+with a test or workflow-lint covering the **absent-identity / unauthorized /
+missing-file path** that asserts the gate **FAILS** (not skips, not passes).
+Add or update that coverage in the **same PR** that adds or changes the gate.
+A gate without a proven failure path is not yet a gate.
+
+### Violations seen in this codebase (all merge-blocking if reintroduced)
+
+- **serving-e2e** reporting vacuously GREEN when the Infisical identity is
+  absent (no per-(provider × auth) completion was actually exercised).
+- **branch-protection / BP-drift lints** returning `0` on a `403` instead of
+  failing closed on the unverifiable response.
+- **verify-template-models** run without `-strict`, so a drift it could not
+  confirm passed silently.
+- A **referenced-but-absent pytest file** that collects zero tests and reports
+  green — silent pass with no assertions executed.
+
+Each of these is a fail-open gate and is a merge blocker until it fails loud and
+closed on protected contexts. See also the production fail-closed defaults in
+`runbooks/sop-production-cicd.md` (*Production Defaults*), which apply the same
+principle to deploy-time gates.

+# now fail-CLOSED in EVERY environment, dev included. There is NO dev-mode

 #
-#   MOLECULE_ENV=development AND ADMIN_TOKEN unset
+# The clean way to keep the canvas working locally is to provision a
+# deterministic ADMIN_TOKEN and hand the matching NEXT_PUBLIC_ADMIN_TOKEN to
+# the canvas bundle. The canvas already attaches `Authorization: Bearer
+# $NEXT_PUBLIC_ADMIN_TOKEN` on every platform call (canvas/src/lib/api.ts),
+# and next.config.ts warns if the pair is half-set. We set BOTH here.
 #
-# That makes middleware.isDevModeFailOpen() return true and lets the

-# would BREAK the canvas (it has no way to read that token in dev).

+# History: this file used to assert the local-dev fail-open escape hatches
+# (GET /workspaces 200 with NO bearer, /workspaces/:id/activity 200 with no
+# bearer) added in fix/quickstart-bugless. Under the CTO "nothing should be

+# auth is fail-CLOSED in EVERY environment, local dev included. This suite now
+# pins the inverse contract — bearer-less admin/workspace requests 401, and the
+# SAME requests with the dev ADMIN_TOKEN bearer succeed.
 #
-# Requires: platform running on :8080 with MOLECULE_ENV=development and

+# What it verifies:
+#   1. GET /workspaces 401s with NO bearer once tokens exist (was: 200 via the

+#   2. GET /workspaces/:id/activity (and /delegations, /approvals/pending) 401
+#      with no bearer (was: 200 via the WorkspaceAuth hatch); 200 WITH bearer.
+#   3. GET /org/templates returns the curated set populated by clone-manifest.sh
+#      (unauth-readable bootstrap surface — unchanged).
+#
+# Requires: platform running on :8080 with MOLECULE_ENV=development AND

+# `E2E API Smoke Test` merge gate pass without exercising a single
+# runtime (false-green).
+#
+# Fix: a real "validated arm" counter (VALIDATED) tracks runtimes that
+# actually ran AND produced a non-error A2A reply. With E2E_REQUIRE_LIVE=1:
+# if zero arms validated, the run exits NON-zero with a loud message.
+# Without it (E2E_REQUIRE_LIVE unset/0), a fully-skipped run stays a LOUD
+# skip + exit 0 for dev convenience.
+#
+# This zero-validated→RED decision is the load-bearing logic. It is factored
+# into evaluate_require_live_gate() (a pure function of $FAIL/$VALIDATED/
+# $E2E_REQUIRE_LIVE, defined before any platform I/O) and is REGRESSION-GATED
+# on every PR by tests/e2e/test_require_live_priority_gate_unit.sh, which
+# sources this file (E2E_PRIORITY_UNIT_SOURCE=1), sets the counters, and
+# asserts the gate's exit code — no platform, no provisioning, no network.
+# So the false-green can't silently come back: a revert of the guard fails CI.
+#
+# CI POSTURE (REQUIRE-LIVE ON — see .gitea/workflows/e2e-api.yml):
+# The live e2e-api job SETS E2E_REQUIRE_LIVE=1. The `mock` arm is the
+# CI-provisionable live-completion arm: it org-imports a mock workspace
+# (→online→canned A2A reply) with NO external secret. The only thing that
+# previously blocked it in CI was admin auth — POST /org/import and POST
+# /admin/workspaces/:id/tokens are AdminAuth-gated, and the job set no admin
+# token, so every admin call 401'd ("admin auth required"). The job now sets
+# ADMIN_TOKEN on the platform AND exports the matching MOLECULE_ADMIN_TOKEN
+# the scripts send, so mock validates end-to-end and VALIDATED>=1 holds on a
+# healthy platform — the REQUIRED `E2E API Smoke Test` gate now HONESTLY
+# validates a runtime. If the mock plumbing or the admin-auth wiring breaks,
+# the gate goes RED (not false-green). The zero-validated→RED decision is also
+# regression-gated WITHOUT provisioning by the bash unit test above, so a
+# revert of that logic still fails CI.
+#
+# LIVE ARMS (run when their prerequisite is present; opportunistic):
+#   - `mock` (run_mock) is the no-key REQUIRE-LIVE backbone: a virtual
+#     workspace (no container, no EC2, no provider) whose org-import path
+#     short-circuits to status='online' with a canned A2A reply. It validates
+#     in CI now that the e2e-api job wires an admin token (org-import + token
+#     mint are AdminAuth-gated), so it is the guaranteed >=1 validation.
+#   - MiniMax (E2E_MINIMAX_API_KEY, from MOLECULE_STAGING_MINIMAX_API_KEY) is
+#     an OPPORTUNISTIC best-effort real-LLM arm: registry-fragile in CI (422
+#     UNREGISTERED_MODEL_FOR_RUNTIME — see run_minimax header), so a miss is
+#     a best-effort MISS via bestfail() and does NOT red the gate.
+# The CI e2e-api job sets E2E_REQUIRE_LIVE=1: mock guarantees a validation, so
+# the REQUIRED gate is honest (RED if the mock plumbing/admin-auth breaks). The
+# zero-validated→RED logic is also regression-gated by the bash unit test above.
+#

+# MiniMax live arm — OPPORTUNISTIC (best-effort) real-LLM arm.
+####################################################################
+# NOTE: this is now a BEST-EFFORT arm, not the REQUIRE-LIVE backbone.
+# mock (run_mock above) is the guaranteed, no-key validation that keeps
+# the gate honest. This arm uses the BARE registered BYOK id `MiniMax-M2.7`
+# (NOT the colon `minimax:MiniMax-M2.7`): on claude-code the colon form is
+# INTENTIONALLY unregistered — the claude-code adapter cannot strip the
+# `minimax:` prefix, so DeriveProvider rejects it 422
+# UNREGISTERED_MODEL_FOR_RUNTIME before any provisioning (provider-registry
+# SSOT, internal#718; pinned by derive_provider_matrix_test.go's
+# colon-vs-slash-vs-bare triple, and observed on real staging job 295075).
+# The bare id is in claude-code's `minimax` arm (registry_gen.go:88
+# Models=[MiniMax-M2,MiniMax-M2.7,MiniMax-M2.7-highspeed,MiniMax-M3]) and
+# derives provider=minimax (BYOK via MINIMAX_API_KEY), so create-validation
+# accepts it. This arm stays BEST-EFFORT (bestfail, non-gating) for transient
+# MiniMax provisioning / backend issues — mock carries the REQUIRED gate; if
+# MiniMax DOES come up it validates as a bonus real-LLM check.
+# Drives the claude-code runtime against MiniMax (BYOK) using the
+# already-present Gitea secret MOLECULE_STAGING_MINIMAX_API_KEY,
+# surfaced into the env as E2E_MINIMAX_API_KEY (same name + secret the
+# staging-smoke / continuous-synth canaries use — see staging-smoke.yml
+# and continuous-synth-e2e.yml). NO new credential is introduced.
+#
+# Why this is the arm that keeps the REQUIRED gate honest:
+#   - claude-code's `minimax` provider (providers.yaml / registry_gen.go)
+#     is third_party_anthropic_compat: it reads MINIMAX_API_KEY at boot
+#     and routes ANTHROPIC_BASE_URL → api.minimax.io/anthropic. So the
+#     ONLY tenant secret needed is {"MINIMAX_API_KEY": <key>} — exactly
+#     the SECRETS_JSON branch test_staging_full_saas.sh uses.
+#   - Model id is the BARE `MiniMax-M2.7`, the registered BYOK arm for
+#     claude-code (registry_gen.go:88 Runtimes["claude-code"]["minimax"]
+#     Models). DeriveProvider routes bare → provider=minimax (BYOK). The
+#     colon-namespaced `minimax:MiniMax-M2.7` is UNREGISTERED on claude-code
+#     (the adapter can't strip `minimax:`; internal#718) and 422s create —

+# Fail-direction / load-bearing proof for the E2E_REQUIRE_LIVE zero-validated
+# gate in test_priority_runtimes_e2e.sh (the REQUIRED `E2E API Smoke Test`).
+#
+# WHY (harden/enforce-ci-gates-core-v2, PR #2286): the priority-runtimes E2E's
+# only historical exit gate was `[ "$FAIL" -eq 0 ]`. When every runtime SKIPs
+# because no live secret is present — exactly what the CI step did — PASS=0
+# FAIL=0 and the script exited 0 (GREEN) while validating ZERO runtimes. The
+# REQUIRED merge gate was therefore false-green: passing without exercising a
+# single runtime. The fix adds a VALIDATED counter and makes a zero-validated
+# run RED when E2E_REQUIRE_LIVE is set.
+#
+# That zero-validated→RED decision lives in evaluate_require_live_gate() in
+# test_priority_runtimes_e2e.sh. CI cannot prove it via a live arm — the CI
+# substrate can't provision ANY runtime end-to-end (MiniMax 422, mock org-
+# import create fails, claude-code needs a key CI lacks), so the live e2e-api
+# job does NOT force E2E_REQUIRE_LIVE (that would red the required gate for
+# everyone). This UNIT test is the regression coverage instead: it drives the
+# REAL evaluate_require_live_gate() function — not a copy — in isolation by
+# sourcing the script with E2E_PRIORITY_UNIT_SOURCE=1 (which stops before any
+# platform I/O), setting the counters, and asserting the gate's return code.
+#
+# Because it exercises the actual function, a future revert of the zero-
+# validated→RED logic in test_priority_runtimes_e2e.sh fails THIS test on
+# every PR — so the false-green can't silently come back.
+#

+# HERMES_CUSTOM_API_KEY/_BASE_URL, etc. A bare vendor key in the CREATE payload
+# does NOT auto-derive byok: at create time no auth-env is present yet, so the
+# resolver derives platform_managed and the write is rejected. The resolver's
+# org rung was retired (internal#718 P2-B) — ResolveLLMBillingMode now ignores
+# the org default — so the ONLY way to opt a workspace into byok is an explicit
+# per-workspace override via PUT /admin/workspaces/:id/llm-billing-mode.
+#
+# Real evidence — staging job 295385 (main f1558b54), AFTER #2311/#2312 made
+# bare `MiniMax-M2.7` registry-valid: parent-create passed model validation but
+# FAILED with
+#   {"error":"direct vendor key writes are blocked for platform-managed
+#    workspaces; ... or set this workspace's billing mode to 'byok' via
+#    /admin/workspaces/:id/llm-billing-mode","key":"MINIMAX_API_KEY"}
+# That 400 is INTENDED product behavior, not a product bug. The e2e must mirror
+# the real BYOK user flow: opt the workspace into byok FIRST, then write the key.
+#
+# Mechanism: per-workspace override (NOT org-default), because the org rung is
+# retired — an org-create billing field could not satisfy this gate even if
+# /cp/admin/orgs accepted one. So for any arm that ships strip-listed keys we:
+#   1. create the workspace WITHOUT those keys (create succeeds platform_managed),
+#   2. PUT billing-mode=byok on that workspace id (per-tenant admin token),
+#   3. write the deferred strip-listed keys (now allowed by the gate),
+# then continue. The #1994 byok-routing guard (8c) then sees a LEGITIMATELY
+# byok workspace (explicit override) and still validates real routing — NOT
+# masked.
+#
+# The PLATFORM path (E2E_LLM_PATH=platform) produces SECRETS_JSON='{}', so it
+# carries NO strip-listed key → CREATE_SECRETS_JSON stays '{}' and no opt-in
+# fires. It remains platform_managed (the moonshot/kimi NOT_CONFIGURED
+# regression guard) — deliberately untouched.

+// a2a_full_body_delivery_guard_test.go — regression guard for core#2175.
+//
+// core#2175 RCA: the long-believed "A2A truncation" was a MISDIAGNOSIS.
+// A2A message delivery preserves the FULL body on every agent-facing path.
+// Only HUMAN-facing DISPLAY previews are capped (activity title 80 runes,
+// broadcast 120, delegation summary 80, canvas response_preview 200 bytes).
+// Those caps live on display/broadcast fields, NOT on the bytes an agent
+// reads off the wire.
+//
+// This file locks in the correct behaviour so a FUTURE change cannot
+// silently reintroduce REAL truncation on the agent-facing delivery paths:
+//
+//   1. DequeueNext (a2a_queue.go) — the drain/read path does
+//      `SELECT ... body::text ...` and returns item.Body. The delivered
+//      body MUST equal the enqueued body byte-for-byte.
+//
+//   2. toolCheckTaskStatus (mcp_tools.go) — reads activity_logs.response_body
+//      and surfaces result["result"] = extractA2AText(responseBody). The
+//      returned text MUST be the COMPLETE response text, not a preview.
+//
+// Both bodies used here are WELL over 200 chars (> the largest preview cap,
+// canvas response_preview at 200 bytes) so a regression that wired any
+// display cap into a delivery path would fail loudly.
+//
+// Style: matches the sibling a2a_queue_test.go / mcp_tools_test.go — sqlmock,
+// no integration build tag. These paths are deterministically exercisable
+// against the mock because the truncation guard is about what the Go code
+// does with the row value, not about Postgres-side text handling. CI's
+// real-PG integration arm (a2a_*_integration tests) additionally exercises
+// the live `body::text` round-trip.

-// `ADMIN_TOKEN` and rebuilds the Canvas bundle with a matching
-// `NEXT_PUBLIC_ADMIN_TOKEN`. That's too much friction for a local smoke
-// test — hence the hatch.

+//     (127.0.0.1) in local dev. This is strictly *safer* than binding all
+//     interfaces and is unrelated to whether a request is authenticated.
+//
+// Local dev now stays AUTHENTICATED, not open: scripts/dev-start.sh

+//     "one id, two auth arms" codex/anthropic shape) — so a newly-added model is
+//     AUTO-COVERED and a misrouted one fails RED naming the mismatch.
+//   - NAME-ONLY arms (a runtime ref with zero Models — pure prefix-routing BYOK):

+//
+// Every asserted (runtime, model) is ALSO checked for registration-validity
