refactor(workspace-server): drop org-tier from llm_billing_mode resolver (internal#691)

Per CTO direction 2026-05-26: there is no org-level llm_billing_mode policy. The workspace is the unit of decision. The resolver becomes workspaces.llm_billing_mode ?? "platform_managed" (constant bootstrap floor) The org-tier silently shadowed every workspace without an explicit override when the org default landed on platform_managed (today's agents-team incident on 3 workspaces) — that is the exact failure mode this removal eliminates. Changes - ResolveLLMBillingMode signature drops orgMode parameter; only the workspace row is consulted. NULL / row-missing / garbled / DB-error all resolve via constant_fallback to platform_managed. - BillingModeResolution: drop OrgDefault field; drop BillingModeSourceOrgDefault. Only BillingModeSourceWorkspaceOverride and BillingModeSourceConstantFallback remain. - llm_billing_mode_handler: stop reading MOLECULE_LLM_BILLING_MODE env var. - secrets.go: drop legacy org-level shims (platformManagedLLMMode + the global SetGlobal gate). Per-workspace strip is the only gate; provision- time applyPlatformManagedLLMEnv still strips global-secret leaks for platform_managed workspaces. - workspace_provision.applyPlatformManagedLLMEnv: drop the orgMode env read. - Tests: drop t.Setenv("MOLECULE_LLM_BILLING_MODE", ...) from apply* tests (empty workspaceID short-circuits via constant fallback); the byok-noop case now mocks an explicit workspace override. Resolver table-driven test drops org-as-input cases. Backward compat - workspaces.llm_billing_mode column unchanged; the byok writes done today for agents-team's 3 workspaces are honored exactly as before. Schema removal of organizations.llm_billing_mode is a separate follow-up. - Strip-list (platformManagedDirectLLMBypassKeys) unchanged.

-    # ── 2026-06-01 CI-scheduler-overload fix (fix/ci-scheduler-fanout) ──
-    # PREVIOUS shape: a poll-gate that ran detect-changes then LOOPED on
-    # `GET /commits/{sha}/statuses` every 15s for up to 40 min, occupying a
-    # `ci-meta` executor slot the entire time it waited for upstream jobs.
-    # With only 2 ci-meta runners, that poll-loop squatted half the lane on
-    # every PR — a confirmed throughput sink in the live RCA (two concurrent
-    # `JOB-all-required` containers observed pinning the lane). The polling
-    # design existed only to dodge the Gitea `needs:` + `if: always()` bug,
-    # where an always()-guarded sentinel could be marked skipped before
-    # upstream jobs settled (leaving BP pending forever).
+    # This job deliberately has no `needs:`. Gitea 1.22/act_runner can mark a
+    # job-level `if: always()` + `needs:` sentinel as skipped before upstream
+    # jobs settle, leaving branch protection with a permanent pending
+    # `CI / all-required` context. Instead, this independent sentinel polls the
+    # required commit-status contexts for this SHA and fails if any fail, skip,
+    # or never emit. It runs the same path detector as `changes` and only waits
+    # for path-relevant jobs; Gitea can otherwise leave needs/output-skipped
+    # jobs permanently pending with "Blocked by required conditions". It runs on
+    # the dedicated `ci-meta` lane so the poller does not occupy the same
+    # general runner pool as the jobs it is waiting for.
    #
-    # NEW shape: a plain `needs:` aggregator with NO polling loop. This is
-    # safe here — and was NOT safe at the time the poller was written —
-    # because every aggregated CI job now gates its real work PER-STEP
-    # (`if: needs.changes.outputs.* != 'true'`) rather than at the JOB level.
-    # A per-step-gated job always reaches a terminal SUCCESS (it no-ops its
-    # expensive steps but the job itself still completes), so it is never
-    # `skipped`. Plain `needs:` (WITHOUT `if: always()`) works correctly on
-    # Gitea 1.22.6 / act_runner v0.6.1 — only `needs:` + `if: always()` is
-    # broken (feedback_gitea_needs_works_only_ifalways_broken). We therefore
-    # use plain `needs:` + an explicit per-need result check (NOT
-    # `if: always()`); if any need fails/errors, Gitea never starts this job
-    # and BP sees `CI / all-required` go red via the failed dependency
-    # propagation — exactly the gate we want, with zero runner-squat.
+    # canvas-deploy-reminder is intentionally NOT included in all-required.needs.
+    # It is an informational main-push reminder, not a PR quality gate. Keeping
+    # it in this dependency list lets a skipped reminder skip the required
+    # sentinel before the `always()` guard can emit a branch-protection status.
    #
-    # The `needs:` list MUST stay in lockstep with ci-required-drift.py's
-    # F1 check (`ci_job_names()` = every job MINUS the sentinel MINUS jobs
-    # whose `if:` gates on github.event_name/github.ref). canvas-deploy-
-    # reminder is event-gated (`if: github.ref == refs/heads/{main,staging}`)
-    # so it is intentionally EXCLUDED — it skips on PRs and a `needs:` on a
-    # skipped job would never let the sentinel run. If a new always-running
-    # CI job is added, add it here too or ci-required-drift F1 will flag it.
-    #
-    # Stays on the dedicated `ci-meta` lane (no docker work, so the

+name: Lint no tenant GITEA or GITHUB token write
+
+# Task #146 — CI guardrail companion to RFC#523's `lint-forbidden-env-keys.yml`.
+#
+# `lint-forbidden-env-keys.yml` (Layer 3) catches code that hardcodes a
+# forbidden env-var key NAME as a quoted literal in workspace_secrets
+# writer paths under workspace-server/internal/.
+#
+# This workflow catches a BROADER class: any code path that reads a
+# repo-host token (GITEA_TOKEN / GITHUB_TOKEN / GH_TOKEN) and then writes
+# it into a TENANT WORKSPACE's env, secret store, user-data, or
+# provision payload. This is the actual RFC#523 threat-model statement —
+# the goal is "no tenant workspace ever receives an operator-scope repo
+# token," not just "no _quoted_ literal `GITEA_TOKEN`." A future writer
+# could route the value via a variable, a struct field, or a config key
+# and slip past the existing literal scan; this lint catches those
+# routing patterns at PR review time.
+#
+# Scope
+#   Scans the WHOLE repo's Go sources (not just workspace-server/) for
+#   co-occurrences of:
+#     - a repo-host token NAME (GITEA_TOKEN / GITHUB_TOKEN / GH_TOKEN /
+#       GITEA_PAT / GITHUB_PAT) used as os.Getenv argument or string
+#       literal
+#     - within a file that ALSO references a tenant-writer surface
+#       (`tenant`, `workspace_secrets`, `global_secrets`, `seedAllowList`,
+#       `/settings/secrets`, `userData`, `provisionPayload`,
+#       `envVars[`, `containerEnv`).
+#
+#   Co-occurrence (not single-line) is the false-positive control: a
+#   file that just LOGS the variable name (e.g. "missing GITEA_TOKEN")
+#   without touching any tenant surface won't fire.
+#
+# Drift contract with lint-forbidden-env-keys.yml
+#   Both lints share the same FORBIDDEN_KEYS list (a subset — only the
+#   repo-host tokens, since this lint's threat model is "tenant gets
+#   write access to operator's git host"). If RFC#523's deny set grows,
+#   update BOTH this file AND lint-forbidden-env-keys.yml AND the Go
+#   source-of-truth in
+#   workspace-server/internal/handlers/workspace_provision_forbidden_env.go.
+#
+# Open-source-template-friendly
+#   The patterns scanned are generic (no MOLECULE_-prefix literals).
+#   A fork can copy this workflow as-is and adjust FORBIDDEN_KEYS.
+#
+# Path-filter discipline
+#   No `paths:` filter — required-status workflows must run on every PR
+#   per `feedback_path_filtered_workflow_cant_be_required`. Scan is
+#   sub-second.

-# 2026-05-27 "Distribution = SDK via codegen + verify-CI", multi-repo branch:
-# "codegen-checked-into-each-repo + verify-CI").
-#
-# The canonical provider-registry SSOT is molecule-controlplane
-# internal/providers/providers.yaml. molecule-core has NO Go module dependency
-# on controlplane, so instead of importing it we carry a SYNCED COPY at
-# workspace-server/internal/providers/providers.yaml and gate it.
-#
-# This workflow fetches the canonical providers.yaml from controlplane (via the
-# Gitea raw endpoint, read-only) and byte-compares it against core's synced
-# copy. RED if they differ — meaning the canonical moved and core's copy must be
-# re-synced (copy verbatim + `go generate ./...` + bump
-# canonicalProvidersYAMLSHA256 in sync_canonical_test.go).
-#
-# Pairs with:
-#   * sync_canonical_test.go — hermetic sha pin (catches a hand-edit of core's
-#     copy even with no network); runs in the normal `go test ./...`.
-#   * verify-providers-gen.yml — artifact ↔ synced-copy drift.
-#
-# ENFORCEMENT GATING: standalone workflow, NOT a job in ci.yml and NOT in
-# branch protection (same soak-then-promote posture as verify-providers-gen).
-# It is intentionally absent from ci.yml's job set so the ci-required-drift
-# sentinel does not fire on it.
-#
-# AUTH: uses AUTO_SYNC_TOKEN (the existing cross-repo read token used to sync
-# template/provider content from sibling repos). If the secret is absent the
-# job emits a clear ::warning:: and exits 0 — the hermetic sha pin in
-# sync_canonical_test.go is the always-on backstop, so a missing cross-repo
-# token degrades to "hand-edit still caught, live canonical drift not caught"
-# rather than a hard red that blocks unrelated PRs.

-# Provider-registry SSOT enforcement gate — molecule-core side (internal#718
-# P2-A, CTO 2026-05-27 "Distribution = SDK via codegen + verify-CI").
-#
-# The canonical schema SSOT is molecule-controlplane
-# internal/providers/providers.yaml. molecule-core carries a SYNCED COPY at
-# workspace-server/internal/providers/providers.yaml (kept in sync by the
-# companion sync-providers-yaml.yml gate), and cmd/gen-providers emits the
-# checked-in Go projection workspace-server/internal/providers/gen/registry_gen.go.
-#
-# This workflow regenerates the artifact into the working tree and fails RED if
-# it differs from what is committed — catching BOTH:
-#   * a providers.yaml (synced-copy) change that wasn't followed by `go generate ./...`, and
-#   * a hand-edit of the generated artifact (it carries a DO NOT EDIT header).
-#
-# It is the molecule-core mirror of molecule-controlplane's verify-providers-gen
-# workflow. Together with sync-providers-yaml (canonical↔synced-copy drift) it
-# closes the codegen-checked-into-each-repo + verify-CI loop the RFC mandates.
-#
-# ENFORCEMENT GATING (deliberate, per dev-SOP "implementation gating"):
-# this is a STANDALONE workflow, NOT a job inside ci.yml, and is NOT yet in any
-# branch-protection status_check_contexts. Rationale (identical to the CP P0
-# rollout):
-#   * It runs + reports RED on every PR/push immediately (visible signal).
-#   * It is intentionally absent from ci.yml's job set so the ci-required-drift
-#     sentinel (jobs ↔ branch-protection ↔ audit-env) does NOT fire on it, and
-#     from branch protection (turning it into a hard merge gate has blast radius
-#     — operator GO required, same pattern as sop-tier-check / verify-providers-gen
-#     on controlplane). Promote it into branch protection in a follow-up once
-#     P2 has soaked.
-# Until then it behaves like secret-scan / block-internal-paths: a standalone
-# advisory-to-hard gate the author is expected to keep green.

- * Focused tests for BudgetSection's PER-PERIOD progress-bar math + aria (#49).
+ * Tests for BudgetSection (issue #541).
 *
- * Behavioral coverage (loading, save, 402 banners, USD formatting, legacy
- * back-compat) lives in tabs/__tests__/BudgetSection.test.tsx — this file
- * deliberately covers only the per-period progress percentage + aria-valuenow
- * + the over-budget colouring, which that suite doesn't assert in detail. Kept
- * separate to avoid duplicating the behavioral suite (one component, no
- * parallel/identical suites).
+ * Covers:
+ *  - Loading state
+ *  - Stats row: used / limit, "Unlimited" when null
+ *  - Progress bar: correct percentage, capped at 100%, absent when no limit
+ *  - Budget remaining text
+ *  - Input pre-fill (existing limit / blank when null)
+ *  - Save: PATCH with number, PATCH with null (blank input)
+ *  - 402 on GET → exceeded banner, no fetch-error text
+ *  - 402 on PATCH → exceeded banner
+ *  - Non-402 fetch error → error text
+ *  - Non-402 save error → save error alert
+ *  - Section header and subheading
+ *  - Fetch error does not show stats

-// internal#718 P4 closure — ConfigTab.billingMode.test.tsx is retired.
+// Tests for the provider → llm_billing_mode linkage (internal#703 Gap 2).
 //
-// This suite (255 lines, 8 tests) pinned the canvas-side provider →
-// llm_billing_mode linkage from internal#703 Gap 2: when the operator
-// changed the PROVIDER in the Config tab, ConfigTab.handleSave would
-// PUT /admin/workspaces/:id/llm-billing-mode so the platform-vs-byok
-// decision tracked the dropdown.
+// What this pins: when the operator changes the PROVIDER in the Config
+// tab, the workspace's llm_billing_mode must follow — a non-Platform
+// provider sets billing_mode=byok; Platform sets platform_managed. Before
+// this wiring, selecting "Claude Code subscription (OAuth)" or any vendor
+// key wrote the credential env but left billing_mode=platform_managed, so
+// CP kept injecting the platform proxy base URL and the OAuth token /
+// vendor key was never used — BYOK silently no-op'd (the live jrs-auto
+// SEO-Agent symptom in #703).
 //
-// That linkage is retired together with the LLM_PROVIDER override flow
-// (see ConfigTab.provider.test.tsx retirement note). P2-B (#1972)
-// moved the platform-vs-byok decision to
-// `ResolveLLMBillingModeDerived(runtime, model, authEnv)` in
-// workspace-server — the canvas can no longer override it via the
-// provider dropdown, by design. The runtime+model selection IS the
-// billing-mode selection now.
-//
-// The `/admin/workspaces/:id/llm-billing-mode` endpoint still exists
-// as the operator override surface (`workspaces.llm_billing_mode`
-// column); it is no longer driven by the provider dropdown.
-// Coverage for the derived billing flow lives in
-// workspace-server/internal/handlers/llm_billing_mode_derived_test.go.
-//
-// Restore from git history if the canvas-side provider→billing linkage
-// needs to be revisited (it should not — the derived resolver is the
-// single decision point).
+// The billing-mode PUT targets the same per-tenant endpoint the LLM

+// that lets the operator override the model→provider derivation hermes-
+// agent does internally. Without this UI, a fresh signup whose Hermes
+// workspace defaults to a model with no clean vendor prefix (e.g.
+// `nousresearch/hermes-4-70b`) hits the runtime's own preflight error:
+//   "No LLM provider configured. Run `hermes model` to select a
+//    provider, or run `hermes setup` for first-time configuration."
+// — even though tasks #195-198 wired the entire downstream pipe so a
+// non-empty provider WOULD flow through canvas → workspace-server →
+// CP user-data → workspace config.yaml → hermes adapter.
 //
-//   - workspace-server SetProvider / GetProvider (PUT/GET
-//     /workspaces/:id/provider) → both return 410 Gone with a

+// Hongming Wang hit this on hongming.moleculesai.app at signup

-// ConfigTab still renders the provider dropdown for display (the user

-// round-trips the value. The replacement contract is that the provider
-// is DERIVED at every decision point from (runtime, model) via the

-# Engineer-Agent Gitea Token Scope Runbook
-
-## Symptom
-
-Engineer-class agents (e.g. `agent-dev-a`, `agent-dev-b`) fail swarm-pull issue discovery or receive HTTP 403 when calling Gitea issue-list APIs, while PR review and repository API operations continue to work.
-
-Typical failing call:
-```bash
-GET /api/v1/repos/molecule-ai/molecule-core/issues?state=open&labels=approved&limit=50
-# => 403 Forbidden
-```
-
-Typical working calls (same token):
-```bash
-GET /api/v1/repos/molecule-ai/molecule-core/pulls?state=open&limit=50
-POST /api/v1/repos/molecule-ai/molecule-core/pulls/1666/comments
-# => 200 OK
-```
-
-## Root Cause
-
-Gitea v1.22.6 routes issue-list under the `Issue` scope category (`routers/api/v1/api.go:1379-1491`), while PR routes live under repository/pull routing (`api.go:1278-1305`). The scope gate derives required read/write level from HTTP method (`api.go:309-313`), so `GET /issues?...` requires `read:issue`.
-
-Engineer-class agent PATs were provisioned with repository and PR scopes but without `read:issue`, causing the asymmetric 403.
-
-## Detection
-
-1. **Agent-side**: swarm-pull workflow logs show `403 Forbidden` on issue enumeration but not on PR list/review.
-2. **Platform-side**: Gitea access logs show `GET /repos/{owner}/{repo}/issues` returning 403 for the affected token.
-3. **Reproduction** (from any workspace with a suspected token):
-   ```bash
-   TOKEN=$(cat /configs/secrets.d/GITEA_TOKEN)
-   PLATFORM="https://git.moleculesai.app"
-
-   # Should succeed — confirms token is live
-   curl -s -o /dev/null -w "%{http_code}" \
-     -H "Authorization: token $TOKEN" \
-     "$PLATFORM/api/v1/user"
-
-   # Will 403 if the token lacks read:issue
-   curl -s -o /dev/null -w "%{http_code}" \
-     -H "Authorization: token $TOKEN" \
-     "$PLATFORM/api/v1/repos/molecule-ai/molecule-core/issues?state=open&limit=1"
-   ```
-
-## Immediate Fix
-
-### Step 1: Issue fresh PATs with correct scopes
-
-From a Gitea site-admin account (or via the Gitea web UI → Settings → Applications):
-
-1. Navigate to the affected user's profile (e.g. `agent-dev-a`).
-2. Go to **Settings → Applications → Generate New Token**.
-3. Select scopes:
-   - `read:repository` (existing)
-   - `write:repository` (existing, if push is required)
-   - `read:issue` (**add this**)
-   - `write:issue` (add only if agents must comment/edit issues)
-   - `read:pull-request` / `write:pull-request` (existing)
-   - `read:comment` / `write:comment` (existing, if PR review is required)
-4. Copy the plaintext token immediately — it is shown only once.
-
-### Step 2: Update workspace secrets
-
-For each affected engineer workspace, update the Gitea token secret:
-
-```bash
-# Via the platform API (admin auth required)
-PLATFORM="https://agents-team.moleculesai.app"
-ADMIN_TOKEN="<your-admin-token>"
-WORKSPACE_ID="<affected-workspace-id>"
-NEW_GITEA_TOKEN="<fresh-token-from-step-1>"
-
-curl -X POST "$PLATFORM/workspaces/$WORKSPACE_ID/secrets" \
-  -H "Authorization: Bearer $ADMIN_TOKEN" \
-  -H "Content-Type: application/json" \
-  -d "{
-    \"GITEA_TOKEN\": \"$NEW_GITEA_TOKEN\"
-  }"
-```
-
-Restart the workspace so the runtime re-reads secrets:
-```bash
-curl -X POST "$PLATFORM/workspaces/$WORKSPACE_ID/restart" \
-  -H "Authorization: Bearer $ADMIN_TOKEN"
-```
-
-### Step 3: Smoke-test
-
-From the restarted workspace, verify all three paths:
-
-```bash
-# 1. Issue list (the previously failing path)
-curl -s -H "Authorization: token $GITEA_TOKEN" \
-  "https://git.moleculesai.app/api/v1/repos/molecule-ai/molecule-core/issues?state=open&labels=approved&limit=1" | jq '.[0].number'
-
-# 2. PR list (should still work)
-curl -s -H "Authorization: token $GITEA_TOKEN" \
-  "https://git.moleculesai.app/api/v1/repos/molecule-ai/molecule-core/pulls?state=open&limit=1" | jq '.[0].number'
-
-# 3. Swarm-pull discovery (end-to-end)
-# Trigger the agent's autonomous tick or delegate a task that enumerates open issues.
-```
-
-## Long-Term Fix
-
-Update the **workspace secret injection path** that writes `/configs/secrets.d/GITEA_TOKEN` for engineer-class agents. The provisioning template or secret-distribution job should request `read:issue` (and optionally `write:issue`) at token-creation time.
-
-File locations to audit:
- `.gitea/scripts/` — any token-provisioning automation
- `infra/terraform/` or equivalent — IAM/secret-manager templates
- `workspace-configs-templates/` — engineer-class workspace templates that declare required secrets
-
-## Prevention
-
-1. **Token scope checklist**: when provisioning new engineer-class agent tokens, verify the scope set includes `read:issue` before distributing the secret.
-2. **Monitoring**: add an agent health-check that probes `GET /repos/molecule-ai/molecule-core/issues?limit=1` and surfaces a non-fatal warning if it returns 403.
-3. **Documentation**: update the onboarding runbook for new engineer agents to include the full required scope list.

+Google's Agent Development Kit (ADK) is now a first-class runtime on Molecule AI. This tutorial walks you from zero to a running ADK agent workspace — one that persists per-conversation session state and sits alongside your Claude Code and Gemini CLI workers in the same A2A network.

-Google's Agent Development Kit (ADK) runs as a Molecule AI workspace runtime:
-ADK is the **agent engine** (`LlmAgent` + `Runner`), and the workspace
-participates in Molecule's A2A org like any other runtime.
+## What you'll need

-## How it actually works
+- A Molecule AI account with at least one provisioned tenant
+- A `GOOGLE_API_KEY` from [aistudio.google.com](https://aistudio.google.com) (or Vertex AI credentials — see below)
+- `curl` + `jq`

- **ADK = engine only.** The adapter builds an ADK `LlmAgent` from the
-  workspace config (model + system prompt + tools) and drives its `Runner`.
-  It installs `google-adk[mcp]==2.1.0` and **never** the `[a2a]` extra — ADK's
-  a2a layer pins `a2a-sdk<0.4`, which is incompatible with the platform's
-  `a2a-sdk>=1.0`. (Verified: `google-adk[mcp]==2.1.0` + `a2a-sdk 1.0.3` coexist.)
- **A2A** is provided by the platform's a2a-1.x server; a Molecule-authored
-  executor bridges ADK's `Runner` event stream onto it, one ADK session per
-  A2A `context_id`.
- **Tools** reach the agent via ADK's native `McpToolset` pointed at the
-  workspace's `a2a_mcp_server` — the same MCP surface the CLI runtimes use
-  (`delegate_task`, `commit_memory`, `list_peers`, …). No LangChain.
-
-## Auth — Vertex AI via ADC (keyless), or an AI Studio key
-
-The runtime supports both google-genai auth paths:
-
- **Vertex AI + Application Default Credentials (recommended; required if your
-  org disallows API keys).** Set `model: vertex:gemini-2.5-pro` and provide
-  `GOOGLE_CLOUD_PROJECT`; the adapter sets `GOOGLE_GENAI_USE_VERTEXAI=1` and
-  google-genai authenticates via ADC — no API key. (Locally:
-  `gcloud auth application-default login`.)
- **AI Studio API key** (where your org permits API keys): set
-  `model: google_genai:gemini-2.5-pro` and `GOOGLE_API_KEY`.
-

+# curl -X PUT .../secrets -d '{"key":"GOOGLE_CLOUD_LOCATION","value":"us-central1"}'
 ```

-Send it a task via the A2A proxy (`POST /workspaces/:id/a2a`, JSON-RPC
-`message/send`) and it replies through the ADK `Runner`. Verified end-to-end:
-a Gemini 2.5 round-trip on Vertex via ADC returns through the built image.
+## Expected output
+
+After step 4, ADK streams the Gemini response through its event bus, filters for `is_final_response()` events, and returns the agent's reply as a standard A2A text part. Step 5 should reference the prior answer — the adapter ties each A2A `context_id` to an `InMemorySessionService` session, so conversation state is isolated per task context and survives across calls within the same session.
+
+## How it works
+
+The `google-adk` adapter wraps Google ADK's runner/session model behind the same `AgentExecutor` interface used by every other Molecule AI runtime. On each turn, `GoogleADKA2AExecutor` calls `runner.run_async()` with the incoming message wrapped in a `google.genai.types.Content` object, then drains the event stream until it collects a final-response event. The `google:` model prefix is stripped before being passed to ADK — so `google:gemini-2.0-flash` in your workspace config becomes `gemini-2.0-flash` in the ADK `LlmAgent`. Error class names are sanitized before leaving the executor; raw Google SDK stack traces never reach the A2A caller.
+
+## Mixed-runtime teams
+
+ADK workspaces participate in the same A2A network as Claude Code, Gemini CLI, Hermes, and LangGraph workers. An orchestrator can delegate long-context summarisation to a `google-adk` worker (Gemini 1.5 Pro's 1M token window) while routing tool-use tasks to a `claude-code` worker — with no provider-specific code in the orchestrator itself. Add an ADK peer with `POST /workspaces`, set `GOOGLE_API_KEY`, and it's available for `delegate_task` immediately.

- A PR that was opened **before** the `pull_request_review` trigger was added
-to `qa-review.yml` / `security-review.yml` will **NOT** auto-fire on review,
-because its HEAD still contains the old workflow YAML (no trigger).
-
- A PR that was opened **after** the trigger was added (or that has been
-rebased onto a commit containing the trigger) **WILL** auto-fire, because its
-HEAD contains the new workflow YAML.
-
-### Ops implication
-
-| PR head contains `pull_request_review` trigger? | Behaviour on APPROVED review |
-|---|---|
-| **Yes** (cut from current main, or rebased) | Workflows auto-queue, evaluate, and POST the `(pull_request_target)` context automatically. No slash-command needed. |
-| **No** (stale head, opened before #2157) | Nothing fires. Use `/qa-recheck` + `/security-recheck` slash-commands in a PR comment, OR rebase onto current main. |
-
---
-
-## 2. Standard core-PR flow (post-#2157)
-
-```
-1. Author opens PR from a branch based on current main
-   → qa-review + security-review workflows run on pull_request_target
-   → status contexts post (initial eval, usually red until reviews land)
-
-2. Reviewers submit real APPROVED reviews
-   → If PR head has the trigger: workflows AUTO-FIRE on pull_request_review
-   → Contexts flip green (or stay red if reviewer is not in team)
-
-3. [Optional] If contexts did not flip (stale head, event lost, etc.):
-   → Anyone can comment `/qa-recheck` or `/security-recheck`
-   → sop-checklist.yml refires the evaluator (read-only, idempotent)
-
-4. Both qa-review + security-review contexts are green
-   → Plain Do:merge (no force-merge needed)
-```
-
-### Key point
-
-The `/qa-recheck` and `/security-recheck` commands are a **backstop**, not the
-primary path. PRs cut from current main should auto-fire without manual
-intervention.
-
---
-
-## 3. Diagnosing a stale head
-
-If a PR has real team-member APPROVED reviews but the qa/security contexts
-remain red and no workflow run appears on the PR's "Actions" tab for the
-review event, the PR head is likely stale.
-
-### Quick check
-
-```bash
-# From the PR page, look at the head commit SHA, then:
-curl -sS "https://git.moleculesai.app/api/v1/repos/molecule-ai/molecule-core/contents/.gitea/workflows/qa-review.yml?ref=<HEAD_SHA>" \
-  | jq -r '.content' | base64 -d | grep -c 'pull_request_review'
-# 0  → stale head (no trigger in that version of the workflow)
-# >0 → trigger present; auto-fire SHOULD work (if it didn't, file a tracker)
-```
-
-### Automated diagnostic
-
-The test suite includes `test_gate_stale_head_diagnostic.py`, which reports
-"auto-fire impossible for this PR" when the head lacks the trigger. Run it
-in CI or locally with:
-
-```bash
-PR_NUMBER=123 python -m pytest .gitea/scripts/tests/test_gate_stale_head_diagnostic.py -v
-```
-
---
-
-## 4. Rebasing vs. slash-refire
-
-| Approach | When to use | Trade-off |
-|---|---|---|
-| **Rebase onto current main** | PR is genuinely stale (head lacks trigger OR head is far behind main) | Clean history, gets all recent fixes, but requires force-push and re-approval if the branch was protected |
-| **`/qa-recheck` + `/security-recheck`** | PR head is recent but the review event was missed, or you want to avoid rebase churn | Quick, no force-push, but does NOT fix a missing trigger in the head |
-
-**Do not** use slash-refire as a substitute for rebasing a stale head. If the
-workflow YAML in the PR head does not contain `pull_request_review`, no amount
-of rechecking will make auto-fire work.
-
---
-
-## 5. Live-fire verification
-
-The `test_gate_auto_fire_live.py` regression test exercises the full runtime
-path: it submits an APPROVED review to a test PR and polls for the
-`(pull_request_target)` status contexts. It is skipped when no API token is
-available, and is intended to catch runtime non-fire that static structural
-tests (e.g. `test_gate_review_auto_fire.py`) cannot detect.
-
-Run manually with:
-
-```bash
-export GITEA_HOST=git.moleculesai.app
-export GITEA_TOKEN=<your-token>
-export REPO=molecule-ai/molecule-core
-export LIVEFIRE_PR_NUMBER=<test-pr-number>
-python -m pytest .gitea/scripts/tests/test_gate_auto_fire_live.py -v
-```

-# for the staging full-SaaS E2E (tests/e2e/test_staging_full_saas.sh).
-#
-# WHY THIS LIB EXISTS (molecule-core#1995 / #1994 follow-on):
-# The A2A e2e historically asserted only response SHAPE — e.g.
-# test_a2a_e2e.sh:`check "SEO response has text" '"kind":"text"'`. A fully
-# BROKEN agent returns its error AS a text part:
-#     {"kind":"text","text":"Agent error (Exception) — see workspace logs..."}
-# which STILL matches `"kind":"text"` → the shape check PASSES on a broken
-# agent. That is exactly why the 2026-05-2x drained-key / byok-misroute
-# failures (agents-team PM + reno marketing erroring on every LLM call)
-# sailed through CI. "Channel returns text shape" != "agent actually
-# completed an LLM round-trip".
-#
-# These helpers add three load-bearing gates ON TOP of (never replacing) the
-# existing shape + PONG checks:
-#   1. a2a_assert_real_completion  — deterministic known-answer round-trip
-#      (CONTAINS the expected token AND NOT an error-as-text payload).
-#   2. provider_liveness_matrix    — per-offered-provider cheap completion
-#      probe, providers sourced from the providers.yaml SSOT runtimes block.
-#   3. assert_byok_not_platform_proxy — #1994 regression guard: a
-#      byok-resolving workspace must NOT resolve to platform_managed.

-# Conventions: reuses the host script's fail()/ok()/log() + tenant_call().
-# Source this AFTER those are defined. BASH 4+.

-// "Distribution = SDK via codegen + verify-CI"). It is the byte-for-byte mirror
-// of molecule-controlplane's cmd/gen-providers (the canonical generator). It
-// reads core's SYNCED COPY of the schema — internal/providers/providers.yaml
-// (via the providers loader, so it shares the SAME parse + validation as the
-// runtime) — and emits a checked-in Go artifact:
-//
-//	internal/providers/gen/registry_gen.go
-//
-// The artifact is a deterministic projection of the merged registry: the
-// provider catalog + per-runtime native sets as Go literals, plus the schema
-// version and a content fingerprint. It is core's leaf of the multi-language SDK
-// layer the RFC calls for (Go(CP+core)/TS(canvas)/Python(adapters)).
-//
-// CONTRACT for P2-A (zero behavior change): the generated artifact is
-// checked-in + drift-gated ONLY. NO production code path imports
-// internal/providers/gen — the gen-import-boundary test pins that. P2-B wires
-// the billing/credential decision onto the LOADER (DeriveProvider/IsPlatform),
-// not the raw gen literals. The generator is the build-time half;
-// verify-providers-gen.yml is the CI half that regenerates and fails RED on any
-// diff (drift or hand-edit); sync-providers-yaml.yml gates the synced copy
-// against the controlplane canonical.
