fix(handlers): add $6 placeholder for 'pending' in insertMCPDelegationRow

The INSERT has 8 column names but the VALUES clause only had 5 positional placeholders ($1-$5). The 'pending' status was passed as a raw string literal instead of a placeholder, and pq's internal arg count then misaligned all subsequent args. Before (broken): VALUES ($1...$5, 'pending') with 6 args → pq error After: VALUES ($1...$6) with 6 args → correct Also adds sqlmock coverage for insertMCPDelegationRow (success + DB error) and updateMCPDelegationStatus (success + error detail + DB error logged-not-returned), bringing both from 0% to 100% coverage.

-# RFC#523 Layer 3 (task #146): scan workspace_secrets-writer Go code
-# under workspace-server/ for new code that hardcodes a forbidden
-# operator-scope env var NAME (GITEA_TOKEN, CP_ADMIN_API_TOKEN,
-# RAILWAY_TOKEN, INFISICAL_OPERATOR_TOKEN, MOLECULE_OPERATOR_*, …).
-#
-# Catches the class "a new writer accidentally widens the propagation
-# set" — e.g. a future env-mutator plugin that sets envVars["GITEA_TOKEN"]
-# directly. Today the L1 runtime guard would abort the provision, but
-# this lint surfaces the offending code at PR review time instead of
-# at first provision attempt.
-#
-# Companion layers:
-#   - L1: workspace-server/internal/handlers/workspace_provision_forbidden_env.go
-#         (fail-closed abort at provision time)
-#   - L2: workspace/entrypoint.sh top-of-file env-grep + exit 1
-#
-# Open-source-template-friendly: the deny pattern is generic. A fork
-# can copy this workflow and replace OPERATOR_KEY_PATTERN with its
-# own operator-scope key names.
-#
-# Path-filter discipline:
-#   This workflow runs on every PR (no paths: filter — see
-#   feedback_path_filtered_workflow_cant_be_required). The scan itself
-#   targets workspace_secrets-writer paths via grep -r; it's fast
-#   (sub-second) so unconditional run is fine.

+# Runs the canary smoke suite against the staging canary tenant fleet

+# the prod tenant fleet's 5-minute auto-updater picks up the verified

+# prod is untouched.
+#
+# Registry note (2026-05-10): This workflow previously used GHCR
+# (ghcr.io/molecule-ai/platform-tenant) — that registry was retired
+# during the 2026-05-06 Gitea suspension migration when publish-
+# workspace-server-image.yml switched to the operator's ECR org
+# (153263036946.dkr.ecr.us-east-2.amazonaws.com/molecule-ai/
+# platform-tenant). The GHCR → ECR migration was never applied to
+# this file, so canary-verify was silently smoke-testing the stale
+# GHCR image while the actual staging/prod tenants ran the ECR image.
+# Result: smoke tests could not catch a broken ECR build. Fix:
+#   - Wait step: reads SHA from running canary /health (tenant-
+#     agnostic, works regardless of registry).
+#   - Promote step: calls CP redeploy-fleet endpoint with target_tag=
+#     staging-<sha>, same mechanism as redeploy-tenants-on-main.yml.
+#     No longer attempts GHCR crane ops.
+#
+# Dependencies:
+#   - publish-workspace-server-image.yml publishes :staging-<sha>
+#     to ECR on staging and main merges.
+#   - Canary tenants are configured to pull :staging-<sha> from ECR
+#     (TENANT_IMAGE env set to the ECR :staging-<sha> tag).

+# Users see stale code indefinitely.
+#
+# This workflow closes the gap by calling the control-plane admin

+# Registry: ECR (153263036946.dkr.ecr.us-east-2.amazonaws.com/

+# Runtime ordering:
+#   1. publish-workspace-server-image completes → new :staging-<sha> in ECR.

+# Mirror of redeploy-tenants-on-main.yml, with the staging-CP host and
+# the :staging-latest tag. Sister workflow exists for prod (rolls
+# :latest after canary-verify). Both share the same shape — just
+# different CP_URL + target_tag + admin token secret.
+#
+# Why this workflow exists: publish-workspace-server-image now builds
+# on every staging-branch push (PR #2335), pushing
+# platform-tenant:staging-latest to GHCR. Existing tenants pulled
+# their image once at boot and never re-pull, so the new image just
+# sits unused until the tenant is reprovisioned.
+#
+# This workflow closes the gap by calling staging-CP's
+# /cp/admin/tenants/redeploy-fleet, which performs a canary-first,
+# batched, health-gated SSM redeploy across every live staging tenant.
+# Same endpoint shape as prod CP — only the host differs.
+#
+# Runtime ordering:
+#   1. publish-workspace-server-image completes on staging branch →
+#      new :staging-latest in GHCR.
+#   2. This workflow fires via workflow_run, waits 30s for GHCR's CDN
+#      to propagate the new tag.
+#   3. Calls redeploy-fleet with no canary (staging IS canary; we don't
+#      need a sub-canary inside it). Soak still applies to the first
+#      tenant in case of bad-deploy detection.
+#   4. Any failure aborts the rollout and leaves older tenants on the
+#      prior image — safer default than half-and-half state.
+#
+# Rollback path: re-run with workflow_dispatch + target_tag=staging-<sha>

- *  workspace's runtime. Decision: per-runtime default (Hongming
- *  2026-05-15, internal#425 Decisions §2).
- *
- *  - openclaw → `/agent-home` (the agent's identity/state — the
- *    user-facing interesting files for that runtime live in
- *    `~/.openclaw/` inside the container, which `/agent-home` maps to
- *    via the Phase 2b docker-exec backend).
- *  - everything else (claude-code, hermes, external-like, undefined)
- *    → `/configs` (the legacy default — managed config that flows
- *    through the per-runtime indirection in
- *    workspace-server/internal/handlers/template_files_eic.go).
- *
- *  When the runtime is undefined (legacy callers that don't thread
- *  `data` through, or a workspace whose runtime field hasn't loaded
- *  yet) the default is `/configs` — matches today's behaviour, no
- *  surprise.
- *
- *  Note on `/agent-home` pre-Phase-2b: the backend short-circuits
- *  with HTTP 501 and the canonical "implementation pending" body.
- *  The tab renders empty + the error banner explains. This is by
- *  design — lets us land the canvas UX before the backend ships,
- *  per the RFC's phased rollout. The 501 is graceful: it doesn't
- *  poison error toasts or generate "workspace not found" noise.
- *
- *  Adding a new runtime that should default to `/agent-home`: add it
- *  to the agentHomeDefaultRuntimes set below. Adding a runtime that
- *  should default to a different root: extend this function. */

-/**
- * ChatErrorBanner — error-state banner rendered under the chat
- * message list when an agent turn fails or the workspace is offline.
- *
- * internal#212 closes the "see workspace logs for details" pointer-to-
- * nowhere defect:
- *
- *   - The banner now renders the actionable, secret-safe failure
- *     reason that ws-server places on `ACTIVITY_LOGGED.error_detail`
- *     (provider HTTP status + error code + provider's own human
- *     message). The hook (`useChatSocket`) forwards this through
- *     `onSendError`, which the ChatTab routes into this banner's
- *     `message` prop. No hardcoded opaque text in this component.
- *
- *   - A "View activity log" button navigates the user to the Activity
- *     tab where the full row (request body, response body, timing,
- *     full error_detail) lives. Until internal#212, the banner
- *     mentioned "workspace logs" with no link — there is no separate
- *     Logs tab in the side panel; the Activity tab IS the workspace-
- *     logs surface. Routing through the existing tab makes the
- *     reference real instead of dangling.
- *
- *   - The existing Restart button (shown only when the workspace is
- *     offline) is preserved unchanged so the recovery affordance the
- *     old banner offered does not regress.
- *
- * Pure presentational — no socket subscription, no state machine. Easy
- * to unit-test in isolation and easy to compose into the ChatTab.

-# Shared peer-visibility assertion core — runtime/backend-AGNOSTIC.
-#
-# WHY THIS FILE EXISTS
-# --------------------
-# The peer-visibility gate (PR #1298) was staging-only. Per the standing
-# rule that the local prod-mimic stack must run a MANDATORY local-Postgres
-# E2E BEFORE staging E2E (memory: feedback_local_must_mimic_production,
-# feedback_mandatory_local_e2e_before_ship, feedback_local_test_before_
-# staging_e2e), peer-visibility must also run against the local stack.
-#
-# The ASSERTION must be byte-identical between local and staging — only
-# provisioning differs. So the literal MCP `list_peers` call + every
-# anti-proxy / anti-native-fallback guarantee lives HERE, sourced by both
-# tests/e2e/test_peer_visibility_mcp_staging.sh (staging/CP backend) and
-# tests/e2e/test_peer_visibility_mcp_local.sh (local docker-compose
-# backend). If this assertion ever diverges between the two, that is the
-# bug — keep it in one place.
-#
-# THIS IS NOT A PROXY. pv_assert_runtime issues the byte-for-byte
-# JSON-RPC `tools/call name=list_peers` envelope to `POST
-# /workspaces/:id/mcp` using the workspace's OWN bearer token, through
-# the real WorkspaceAuth + MCPRateLimiter middleware chain — the exact
-# call mcp_molecule_list_peers makes from a canvas agent. It does NOT
-# read a registry row, /health, the heartbeat table, or
-# GET /registry/:id/peers.

-# tests/e2e/test_peer_visibility_mcp_staging.sh (PR #1298) codified the
-# literal user-facing peer-visibility path — but staging-only. The
-# standing rule is that the local prod-mimic stack runs a MANDATORY
-# local-Postgres E2E BEFORE staging E2E (memory:
-# feedback_local_must_mimic_production, feedback_mandatory_local_e2e_
-# before_ship, feedback_local_test_before_staging_e2e,
-# feedback_real_subprocess_test_for_boot_path). A staging-only gate means
-# regressions are caught late and expensively on EC2. This is the LOCAL
-# backend: same byte-identical assertion, local docker-compose stack.
-#
-# THE ASSERTION IS NOT A PROXY and is BYTE-IDENTICAL to staging — it is
-# the SAME tests/e2e/lib/peer_visibility_assert.sh::pv_assert_runtime that
-# the staging script calls. It issues the byte-for-byte JSON-RPC
-# `tools/call name=list_peers` envelope to `POST /workspaces/:id/mcp`

-# + MCPRateLimiter middleware chain — the exact call
-# mcp_molecule_list_peers makes from a canvas agent. It does NOT read a
-# registry row, /health, the heartbeat table, or GET /registry/:id/peers.
-#
-# Only PROVISIONING differs from staging:
-#   - staging: POST /cp/admin/orgs (cold EC2 tenant) + per-tenant admin
-#     token + each workspace's auth_token from the POST /workspaces resp.
-#   - local:   POST /workspaces directly against the local stack
-#     (BASE, default http://localhost:8080), MCP bearer minted via
-#     GET /admin/workspaces/:id/test-token (e2e_mint_test_token —
-#     deterministic, gated by MOLECULE_ENV != production). Same model
-#     every other local E2E (test_priority_runtimes_e2e.sh,
-#     test_api.sh) already uses; no new credential/provision flow.
-#
-# It is written to FAIL on today's broken Hermes/OpenClaw behavior and go
-# green only when the in-flight root-cause fixes (Hermes-401 #162,
-# OpenClaw-never-online/MCP-wiring #165) actually land — same gate
-# semantics + exit codes as the staging script. NON-required by design
-# until then (flip-to-required tracked at molecule-core#1296), and NOT
-# masked with continue-on-error (feedback_fix_root_not_symptom).

-// (registry.go: `agent_card = EXCLUDED.agent_card`), so the stored card
-// served at /.well-known/agent-card.json and returned to peers via
-// agent_card_url ends up with name = UUID, description = "", role = null.
-//
-// Fix shape (deliberately minimal, no contract weakening): when the

-// (the placeholder the runtime had no better value for), the PLATFORM —
-// not the agent — substitutes the friendly value from the trusted
-// workspaces row. Identity stays platform-controlled: the agent never
-// gains the ability to self-set its own name/role; the platform sources
-// it from the operator-controlled DB column. We only ever FILL gaps
-// (empty / UUID-placeholder); a card that already carries a real

-// The fallback pair GITEA_USER / GITEA_TOKEN is ALSO set — GITEA_USER
-// survives the denylist (it's an identity, not a credential) and
