test(handlers): add missing DB-error tests for Record and SessionSearch

- TestDelegationRecord_DBInsertFails: verifies 500 on activity_logs insert failure - TestSessionSearch_DBError: verifies 500 on WITH query failure Both are regression coverage for error paths that lacked test coverage. 🤖 Generated with [Claude Code](https://claude.ai/claude-code)

-# Comprehensive Playwright E2E for the unified chat stack (desktop

-# workspace-server, or this workflow file.
-#
-# Architecture:
-#   1. Ephemeral Postgres + Redis (docker, unique container names)
-#   2. workspace-server built from source, started with
-#      MOLECULE_ENV=development (fail-open auth)
-#   3. canvas dev server (npm run dev) on :3000
-#   4. Playwright tests create workspaces via API, point them at an
-#      in-process echo runtime, and exercise the full send/receive
-#      round-trip through the browser.
-#
-# Parallel-safety: same pattern as e2e-api.yml — per-run container names
-# and ephemeral host ports so concurrent jobs on the host-network runner
-# don't collide.

-# WHY A DEDICATED WORKFLOW (not folded into e2e-staging-saas.yml)
-# --------------------------------------------------------------
-# This is the systemic fix for a real trust failure. Hermes and OpenClaw
-# were reported "fleet-verified / cascade-complete" because the *proxy*
-# signals were green (registry registration + heartbeat for Hermes; model
-# round-trip 200 for OpenClaw). A freshly-provisioned workspace asked on
-# canvas "can you see your peers" actually FAILS:
-#   - Hermes: 401 on the molecule MCP `list_peers` call
-#   - OpenClaw: native `sessions_list` fallback, sees no platform peers
-# Tasks #142/#159 were even marked "completed" under this proxy flaw.
-#
-# A dedicated workflow (vs extending e2e-staging-saas.yml) because:
-#   - It must provision MULTIPLE distinct runtimes (hermes, openclaw,
-#     claude-code) in ONE org and assert each sees the others. The
-#     full-saas script is single-runtime-per-run (E2E_RUNTIME) and folding
-#     a multi-runtime matrix into it would conflate concerns and bloat its
-#     already-45-min run.
-#   - It needs its own concurrency group so it doesn't fight full-saas /
-#     canvas for the staging org-creation quota.
-#   - It needs an independent, non-required status-context name so it can
-#     be RED today (the in-flight Hermes-401 / OpenClaw-MCP-wiring fixes
-#     have not landed) WITHOUT wedging unrelated merges — and flipped to
-#     REQUIRED in one branch-protection edit once it goes green
-#     (flip-to-required checklist: molecule-core#1296).
-#
-# THE ASSERTION IS NOT A PROXY. The driving script
-# tests/e2e/test_peer_visibility_mcp_staging.sh issues the byte-for-byte
-# JSON-RPC `tools/call name=list_peers` envelope to `POST
-# /workspaces/:id/mcp` using each 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.
-#
-# HONEST GATE — NO continue-on-error. Per feedback_fix_root_not_symptom a
-# fake-green mask would defeat the entire purpose. This workflow goes red
-# on today's broken behavior and green only when the root-cause fixes
-# actually land. It is intentionally NOT in branch_protections — see PR
-# body for the required-vs-not decision + flip tracking issue.

-# Gitea 1.22.6 / act_runner notes honored:
-#   - No cross-repo `uses:` (feedback_gitea_cross_repo_uses_blocked). The
-#     actions/checkout SHA is the one e2e-staging-canvas.yml already uses
-#     successfully (a mirrored SHA — see #1277/PR#1292 root-cause).
-#   - Per-SHA concurrency, not global (feedback_concurrency_group_per_sha).
-#   - Workflow-level GITHUB_SERVER_URL pinned
-#     (feedback_act_runner_github_server_url).
-#   - pr-validate posts a status under the same check name so a
-#     workflow-only PR is not silently statusless and the context is
-#     flip-to-required-ready (mirrors e2e-staging-saas.yml's proven shape;
-#     real EC2-provisioning E2E is push/dispatch/cron only — it is 30+ min

-# Staging E2E — fresh-provision peer-visibility gate via the LITERAL MCP path.
-#
-# WHY THIS EXISTS
-# ---------------
-# Hermes and OpenClaw were repeatedly reported "fleet-verified / cascade-
-# complete" because the *proxy* signals were green:
-#   - registry-registration + heartbeat (Hermes), and
-#   - model round-trip 200 (OpenClaw).
-# But a freshly-provisioned workspace, asked on canvas "can you see your
-# peers", actually FAILS:
-#   - Hermes: 401 on the molecule MCP `list_peers` call,
-#   - OpenClaw: falls back to native `sessions_list`, sees no platform peers.
-# Tasks #142/#159 were even marked "completed" under this same proxy flaw.
-#
-# This script codifies the LITERAL user-facing path so it can never silently
-# regress: it provisions a brand-new throwaway org + sibling workspaces via
-# the real control-plane provisioning path, then for each runtime that should
-# have platform peer-visibility it drives the EXACT MCP call the canvas agent
-# makes — `POST /workspaces/:id/mcp` JSON-RPC tools/call name=list_peers,
-# authenticated by that workspace's own bearer token through the real
-# WorkspaceAuth + MCPRateLimiter middleware chain. It then asserts:
-#   (1) HTTP 200,
-#   (2) JSON-RPC `result` present (NOT an `error` object — a -32000
-#       "tool call failed" or a 401 from WorkspaceAuth fails here),
-#   (3) the returned peer set CONTAINS the other provisioned sibling
-#       workspace IDs — not an empty list, not a native-sessions fallback.
-#
-# This is NOT a proxy. It does not look at a registry row, /health, the
-# heartbeat table, or `GET /registry/:id/peers`. It drives the byte-for-byte
-# JSON-RPC envelope that mcp_molecule_list_peers issues from a real agent.
-#
-# 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, OpenClaw MCP
-# wiring) actually land. That is the point: it is the objective proof gate.
-#
-# AUTH MODEL (mirrors tests/e2e/test_staging_full_saas.sh)
-# --------------------------------------------------------
-#   Single MOLECULE_ADMIN_TOKEN (= CP_ADMIN_API_TOKEN on Railway staging)
-#   drives: POST /cp/admin/orgs (provision), GET
-#   /cp/admin/orgs/:slug/admin-token (per-tenant token), DELETE
-#   /cp/admin/tenants/:slug (teardown). The per-tenant admin token drives
-#   tenant workspace creation; each workspace's OWN auth_token (returned by
-#   POST /workspaces) drives its MCP call.
-#
-# Required env:
-#   MOLECULE_ADMIN_TOKEN   CP admin bearer — Railway staging CP_ADMIN_API_TOKEN
-# Optional env:
-#   MOLECULE_CP_URL        default https://staging-api.moleculesai.app
-#   E2E_RUN_ID             slug suffix; CI passes ${GITHUB_RUN_ID}
-#   PV_RUNTIMES            space list; default "hermes openclaw claude-code"
-#   E2E_PROVISION_TIMEOUT_SECS  default 1800 (hermes/openclaw cold EC2 budget)
-#   E2E_MINIMAX_API_KEY / E2E_ANTHROPIC_API_KEY / E2E_OPENAI_API_KEY
-#                          LLM provider key injected so the runtime can boot
-#   E2E_KEEP_ORG           1 → skip teardown (local debugging only)
-#
-# Exit codes:
-#   0  every runtime saw its peers via the literal MCP call

+"""OFFSEC-003 regression backstop — sanitize_a2a_result invariant across all A2A tool exit points.
+
+Scope
+-----
+Every public callable in ``a2a_tools_delegation`` that returns peer-sourced content
+must pass its output through ``sanitize_a2a_result`` before returning to the agent
+context.  These tests inject boundary markers and control sequences from a
+mock-peer response and assert the returned value is the sanitized form.
+
+Test coverage for:
+  - ``tool_delegate_task``            — main sync path
+  - ``tool_delegate_task``            — queued-mode fallback path
+  - ``_delegate_sync_via_polling``    — internal polling helper
+  - ``tool_check_task_status``        — filtered delegation_id lookup
+  - ``tool_check_task_status``        — list of recent delegations
+
+Issue references: #491 (delegate_task), #537 (builtin_tools/a2a_tools.py sibling)
+
+Key sanitization facts (for test authors):
+  • _escape_boundary_markers: replaces "[A2A_RESULT_FROM_PEER]" with
+    "[/ A2A_RESULT_FROM_PEER]" and "[/A2A_RESULT_FROM_PEER]" with
+    "[/ /A2A_RESULT_FROM_PEER]". The escape form is "[/ " (bracket-space).
+    Assertion pattern: assert "[/ A2A_RESULT_FROM_PEER]" in result.
+  • Defense-in-depth injection escape patterns replace SYSTEM/OVERRIDE/
+    INSTRUCTIONS/IGNORE ALL/YOU ARE NOW with "[ESCAPED_*]" forms.
+  • Error path: when peer returns an error-prefixed string (starts with
+    _A2A_ERROR_PREFIX), the raw error text is included in the user-facing
+    "DELEGATION FAILED" message. This is intentional — errors from peers
+    are surfaced as errors, not as sanitized results.
