fix(#9663 ): address reviewer-blocked issues from Round R8

Security: replace tempfile.mktemp() with secure mkdtemp()-based temp directory for test database paths, eliminating TOCTOU race condition (Fixes PR Round R8 blocking issue #3). Compatibility: fix Python 3.11 generic syntax - convert class X[T]: to Generic[T] for broader interpreter support. Test quality: fix BDD compression assertion in acms_storage_tiers_steps to properly verify compressed size < original pickled size instead of only checking cold_size > 0 (Fixes PR Round R8 non-blocking issue #4). ISSUES CLOSED: #9580

 ### Fixed

- **Removed undocumented positional `NAME` argument from `agents actor add`** (#5855):
-  The CLI signature is now `agents actor add --config|-c <FILE> [--update] [--unsafe]
-  [--set-default] [--option key=value]`, matching the specification. Actor names are
-  read from the YAML configuration file's `name` field instead of a mandatory CLI
-  positional argument. This brings the implementation into alignment with the spec
-  documentation for v3.2.0 milestone acceptance.
-
-### Changed
-
- **`agents session list` now displays full 26-character session ULIDs** (#10970): The Rich table
-  and Summary panel ("Most Recent" / "Oldest") previously showed only the first 8 characters of
-  each session ULID. This made the output unusable for copy-paste into `session tell`,
-  `session show`, `session delete`, and `session export`, all of which require the full
-  26-character identifier. The full ULID is now displayed in all output formats (Rich, plain,
-  JSON, YAML, table).
-
-### Security
-
- **aiohttp upgraded to >=3.13.4 to remediate CVE-2026-34513 and CVE-2026-34515** (#1549, #1544):
-  Added an explicit `aiohttp>=3.13.4` dependency constraint to `pyproject.toml` to remediate
-  two high-severity open redirect vulnerabilities. Both CVEs affect the CleverAgents platform's
-  HTTP infrastructure including A2A server communication, tool source fetching (MCP servers,
-  Agent Skills), and agent-to-agent protocol handlers. The version floor ensures vulnerable
-  versions (<3.13.4) cannot be installed even if upstream transitive dependencies have loose
-  version constraints.
-
-### Fixed
-
- **Implementation Supervisor PR Compliance Checklist** (#9824): Added a mandatory
-  8-item PR Compliance Checklist to the worker prompt body in `implementation-supervisor.md`
-  that every implementation worker must complete before creating a PR. Checklist covers:
-  CHANGELOG.md update, CONTRIBUTORS.md update, commit footer (`ISSUES CLOSED: #N`),
-  CI verification, BDD tests, Epic reference, label application via `forgejo-label-manager`,
-  and milestone assignment. This eliminates systemic PR merge blockers caused by workers
-  omitting required items.
-
-### Changed
-
- Restored `benchmark-regression` CI job to `master.yml` with `pull_request` trigger guard
-  (`if: forgejo.event_name == 'pull_request'`). The job was previously absent from
-  `master.yml`, causing benchmark regression testing to never run on PRs. The job is
-  informational only and is not in `status-check`'s required needs list. (Closes #10716)
-
- **CI coverage job now waits for unit_tests** (#10714): Added `unit_tests` to the
-  `needs` list of the `coverage` job in `ci.yml`. Previously the coverage job ran
-  in parallel with unit tests, which could produce misleading pass results when
-  tests were still in-flight or had already failed. Coverage now only starts after
-  unit tests succeed, eliminating redundant parallel test execution and ensuring
-  coverage results are always meaningful.
-
- **Bandit B608 f-string SQL in plan phases migration** (#10777): Replaced f-string
-  SQL construction in `a5_005_rebaseline_plan_phases.py` with plain string
-  concatenation. The `INSERT INTO _v3_plans_new ... SELECT ... FROM v3_plans`
-  statement used f-strings to interpolate `_ALL_DATA_COLUMNS`, which Bandit
-  flags as B608 (SQL injection risk). The constant is hardcoded and safe, but
-  the f-string pattern blocks tightening the bandit severity gate from HIGH to
-  MEDIUM (issue #9945). Replaced with `"INSERT INTO _v3_plans_new (" +
-  _ALL_DATA_COLUMNS + ") " "SELECT " + _ALL_DATA_COLUMNS + " FROM v3_plans"`.
-
- **Diagnostics spec examples expanded to all 9 providers** (#5320): Updated the
-  `agents diagnostics` command examples in the specification to show all 9 supported
-  providers (OpenAI, Anthropic, Google, Gemini, Azure, OpenRouter, Cohere, Groq,
-  Together), matching the implementation from PR #3469. Rich, plain, JSON, and YAML
-  example outputs now reflect comprehensive provider coverage with accurate warning
-  counts and per-provider recommendations.
-
-### Added
-
- `agents actor context clear` command to reset actor message history and
-  state while preserving the underlying context directory via `ContextManager`
-  (#6370).
-
- **Plan checkpoint management CLI commands** (#8683): Added `agents plan checkpoint-list <plan-id>` and `agents plan checkpoint-delete <checkpoint-id>` commands. Listing output now highlights checkpoint ID, type, created timestamp, reason, phase, and decision linkage with a concise field summary footer across rich/table/json/yaml formats. Deletion supports batch IDs, interactive confirmation (skip with `--yes`), and structured JSON/YAML responses for automation-friendly scripting.
- **Invariant Remove CLI Command** (#8530): Implemented `agents invariant remove <id>` command that soft-deletes an invariant by ID. The command displays a confirmation prompt before removal (bypassable with `--yes`/`-y`), outputs the removed invariant ID on success, and shows a clear error message when the invariant ID does not exist. Supports `--format` flag for JSON and YAML output. Full BDD test coverage and Robot Framework integration tests included.
- **TDD: MCPToolAdapter.infer_resource_slots() TypeError with null properties** (#10470):
-  Added a TDD issue-capture Behave scenario that reproduces the bug where
-  `MCPToolAdapter.infer_resource_slots()` raises `TypeError` when the input schema
-  contains `{"properties": None}`. The test is tagged `@tdd_expected_fail` and will
-  pass (by inversion) until the underlying bug is fixed.
-
- **Architecture Pool Supervisor Milestone Assignment** (#7521): Added a "PR Workflow
-  for Major Changes" section to the `architecture-pool-supervisor` agent definition
-  documenting the milestone assignment step for spec PRs. The agent now has
-  `forgejo_update_pull_request` permission to assign PRs to the current active
-  milestone after creation, improving traceability of specification changes within
-  project milestone planning. Includes BDD test coverage for the new workflow
-  documentation and permission configuration.
-
- **Git Worktree TOCTOU Race Condition** (#7507): Fixed a Time-Of-Check-To-Time-Of-Use
-  (TOCTOU) race condition in `git_worktree.py` that could cause `git worktree add`
-  operations to fail under concurrent execution. The fix replaces the unsafe
-  `mkdtemp()` + `rmdir()` pattern with a parent-directory approach that maintains
-  the OS-level uniqueness guarantee throughout the entire operation. The parent
-  temporary directory is now persisted and properly cleaned up on both success and
-  failure paths. Comprehensive BDD test coverage validates the fix under concurrent
-  execution and confirms proper cleanup behavior.
-
-### Fixed
-
- **`LLMTraceRepository.save()` premature commit breaks UnitOfWork transactions** (#7505):
-  Replaced the unconditional `session.commit()` in `LLMTraceRepository.save()` with a
-  dual-path implementation that respects the UnitOfWork (UoW) pattern. When an external
-  session is provided (UoW mode), the method now calls only `session.flush()`, leaving
-  transaction control to the caller. When no session is provided (standalone mode), the
-  method creates its own session, flushes, commits, and closes it to ensure durable
-  persistence. This eliminates three data-integrity violations: premature commit of outer
-  UoW transactions, loss of rollback capability for subsequent failures, and a mismatch
-  between the class docstring ("Callers are responsible for commit") and the implementation.
-  Input validation for the `trace` argument was also added. Two new BDD scenarios verify
-  the session contract: `Repository save() calls flush not commit` and `LLM trace rolled
-  back when UnitOfWork transaction rolls back`.
-
- **git_tools._get_base_env() TOCTOU Race Condition** (#7619): Fixed a
-  Time-Of-Check-To-Time-Of-Use race condition in `git_tools._get_base_env()`
-  where two concurrent threads could both observe `_BASE_ENV is None`, both
-  snapshot `os.environ`, and write potentially different snapshots. The fix
-  adds a module-level `_BASE_ENV_LOCK: threading.Lock` and replaces the bare
-  `if _BASE_ENV is None` assignment with double-checked locking: the outer
-  check keeps the warm-cache path lock-free; the inner check inside
-  `with _BASE_ENV_LOCK` prevents duplicate initialisation on the very first
-  concurrent call. Three new BDD scenarios in `features/git_tools.feature`
-  (with step definitions in
-  `features/steps/git_tools_thread_safety_steps.py`) verify caching identity,
-  content correctness, and thread safety under 20 concurrent threads.
-
- **Unified provider factory: eliminate divergence between `create_llm()` and `create_ai_provider()`** (#10949):
-  Introduced `_create_provider_instance()` as the single internal factory so that
-  both public methods delegate to one place.  Creating a new provider now
-  requires changes in exactly one method.
-  - **Fixed API key regression**: the unified factory now explicitly passes
-    the validated API key to all LangChain constructors (OpenAI, Anthropic,
-    Google / Gemini, Azure, Groq, Together, Cohere, and OpenRouter).  Users
-    who configure providers via `CLEVERAGENTS_`-prefixed variables are no
-    longer silently failed when LangChain falls back to raw environment
-    variable lookup.  Pre-validated keys are forwarded through the
-    `api_key` kwarg to avoid a second settings lookup in the factory
-    closure. (Closes #10949)
-  - **Fixed mock provider accessibility in production**: `ProviderType.MOCK`
-    is now gated by the `CLEVERAGENTS_ALLOW_MOCK_PROVIDER=true` sentinel
-    environment variable.  Without this flag, both `create_llm()` and
-    `create_ai_provider()` raise `ValueError` when MOCK is requested,
-    preventing accidental or malicious use of the fake LLM in production.
-    `resolve_provider_by_name("mock")` now also respects the guard and
-    `is_provider_configured(ProviderType.MOCK)` returns `True` as expected.
-  - **Fixed type annotation**: `create_llm()` now declares `**kwargs: Any`
-    instead of `**kwargs: object`, restoring correct Pyright inference for
-    forwarded keyword arguments.
-
- **`create_llm()` raises `Unsupported provider type: openrouter`** (#10948): Fixed
-  `ProviderRegistry._create_provider_llm()` missing an `OPENROUTER` branch, which
-  caused `agents actor run openrouter/<model>` to fail with `ValueError`. Added a
-  `ProviderType.OPENROUTER` branch that creates a `ChatOpenAI` instance configured
-  with `openai_api_base="https://openrouter.ai/api/v1"` and the OpenRouter API key,
-  matching the behavior of `create_ai_provider("openrouter")`. Supports optional
-  `default_headers` kwarg with automatic string coercion for non-string keys/values.
-
- **LoadingThrobber Widget Restored** (#6357): Restored `LoadingThrobber` widget
-
- **Built-in actors v3 YAML format** (#10883): Fixed `agents actor run` failing for
-  built-in actors (e.g., `openai/gpt-4`, `anthropic/claude-3-opus`) due to missing
-  v3 `type` field in stored configuration. `ActorRegistry.ensure_built_in_actors()`
-  now generates and persists v3 YAML text with `type: llm` and `description` fields,
-  ensuring built-in actors work identically to custom actors. The
-  `_generate_builtin_actor_yaml()` helper creates spec-compliant YAML that passes
-  `ReactiveConfigParser._is_v3_format()` validation. Includes BDD scenarios and unit
-  tests covering YAML generation, schema validation, and multiple provider handling.
-
- **Atomic `server_connect` config writes** (#993): Fixed `server_connect` in
-  `cli/commands/server.py` to write all three config values (`server.url`,
-  `server.namespace`, `server.tls-verify`) atomically. A snapshot of the config
-  file is taken before any writes; if any `set_value()` call fails, the snapshot is
-  restored and compensating `CONFIG_CHANGED` events are emitted for already-applied
-  keys so the audit trail reflects the rollback. Added `emit_config_changed()` helper
-  to `ConfigService` for decoupled event emission in rollback flows. Added
-  `close()` method to `ReactiveEventBus` for proper resource cleanup in tests.
-  Resolved merge conflict in `config_service.py` integrating the PR's
-  `emit_config_changed()` helper with master's scoped config infrastructure.
-  Removed `# type: ignore[assignment]` by introducing a typed `_AutoDiscover`
-  sentinel class. BDD regression coverage in
-  `features/tdd_server_connect_atomic_writes.feature`.
-
- **Atomic `load_from_metadata` for Autonomy Guardrails** (#7504): Fixed
-  `AutonomyGuardrailService.load_from_metadata()` to validate both
-  `AutonomyGuardrails` and `GuardrailAuditTrail` models before writing either
-  to state, ensuring atomic updates. Previously, a validation failure on the
-  audit trail after guardrails were already written would leave the system in
-  an inconsistent state with partial updates. The method now uses a two-phase
-  validate-then-write approach: all model validation occurs in Phase 1, and
-  state mutations only happen in Phase 2 after all validations succeed.
-
- **`agents actor run` empty response for built-in LLM actors** (#10861): Fixed
-  `resolve_config_files` in `cli/commands/_resolve_actor.py` silently returning
-  empty output when invoked with a built-in actor name (e.g.
-  `anthropic/claude-sonnet-4-20250514`). Built-in actors generated from the
-  provider registry have a `config_blob` with `provider` and `model` fields but
-  no `type` field. Serialising this blob as-is produced YAML that
-  `ReactiveConfigParser` could not interpret (no agents, no routes → empty
-  `ReactiveConfig` → empty response). Fix: `_synthesize_llm_yaml()` now
-  synthesises a minimal v3 `type: llm` YAML when the actor has no `yaml_text`
-  and the `config_blob` has `provider` and `model` but no `type` field, allowing
-  the reactive config parser to create a working agent and graph route. BDD
-  regression coverage in `features/tdd_actor_run_response.feature`.
-
- **ReactiveConfigParser route synthesis for v3 actors** (#10807): Fixed
-  `agents actor run` silently returning empty output for v3 `type:llm` actors.
-  `_build_from_v3()` and `_build()` now synthesise a default single-node
-  graph route when agents are created without explicit routes, ensuring
-  `run_single_shot()` can invoke the LLM via `GraphExecutor`.  The nested
-  `actors:` map format also translates the v3 `actor: "provider/model"` key
-  into separate `provider` and `model` keys so the correct LLM provider is
-  instantiated.
-
- **ActorRegistry.add() spec-compliant YAML support** (#4466): The registry now
-  accepts actor YAML using the spec's `actors:` map format with nested `config:`
-  blocks, in addition to the legacy top-level `provider`/`model` format. The
-  `unsafe` flag and graph descriptor from nested config are now correctly
-  preserved during registration. Multi-actor YAML (>1 entry in `actors:`/`agents:`
-  map) is now rejected by `add()` with a `ValidationError`. Nested
-  `config.options` are now correctly preserved. The `unsafe` coercion now uses
-  strict `is True or == 1` instead of `bool()` to prevent truthy non-boolean
-  YAML values (e.g. `unsafe: "no"`) from being treated as unsafe.
-
- **UKO Runtime Layer 2 (Paradigm) Indexing** (#9351): Added missing `rdf:type
-  uko-oo:Class` triple emission in `PythonAnalyzer._extract_class()` so that
-  Python class definitions are now correctly classified at layer 2 (paradigm/OO)
-  in addition to layer 3 (technology). Added the corresponding Behave scenario
-  `Indexing a Python file populates layer 2 (paradigm)` to
-  `features/uko_runtime.feature`, completing four-layer guarantee verification
-  for the UKO runtime.
-
- **Actor CLI v3 YAML Schema Support** (#6283): Fixed three components to add
-  full v3 `ActorConfigSchema` support to the actor CLI registration and
-  execution paths.  `ActorConfiguration.from_blob()` now detects v3 format
-  (top-level `type` key of `llm`/`graph`/`tool`) and correctly extracts
-  provider, model, and graph descriptors — including `type: tool` actors
-  without a `model` field.  `ActorRegistry.add()` validates against the full
-  Pydantic v2 schema, persists `skills`/`lsp`/`description` in the config
-  blob, and compiles graph actors with proper metadata.
-  `ReactiveConfigParser._build_from_v3()` now uses correct `source`/`target`
-  edge keys (fixing `KeyError` in `to_graph_config()`), handles `config: null`
-  nodes without crashing, propagates `context_view`/`memory`/`context`/
-  `env_vars`/`response_format`/`lsp_capabilities`/`lsp_context_enrichment`
-  into agent configs, and validates `entry_node` against the nodes map.
-  Exception handling narrowed from broad `except Exception` to specific
-  `NotFoundError` and `ActorCompilationError`.  v3 registration logic
-  extracted to `v3_registry.py` to keep `registry.py` under the 500-line
-  limit.  19 BDD scenarios cover all v3 paths including tool actors,
-  update mode, LSP dict bindings, and field propagation.
-
- **TDD Non-AssertionError Guard Visibility** (#8294): `apply_tdd_inversion` in
-  `features/environment.py` now emits its non-assertion exception guard warning to
-  both the structured logger and `stderr` via a new `_warning_with_stderr` helper.
-  This makes the guard firing visible in standard Behave console output and CI log
-  snippets where the structured logging sink may not be displayed. BDD infrastructure
-  coverage added: a new scenario in `tdd_expected_fail_infrastructure.feature`
-  asserts that the warning is emitted to stderr when a non-AssertionError exception
-  is encountered in an `@tdd_expected_fail` scenario, and a second scenario asserts
-  the warning is NOT emitted when the exception is an `AssertionError`. The
-  `CONTRIBUTING.md` now documents that `@tdd_expected_fail` step definitions must
-  signal expected failures via `AssertionError`.
-
- **Parallel Behave Runner Log Noise Reduction** (#8351): The parallel behave
-  runner now suppresses captured stdout/stderr for passing worker chunks and
-  only replays diagnostics for failed, errored, or crashed chunks.  This makes
-  failure output significantly easier to spot in CI and local runs.  A worker
-  crash (unhandled exception) is detected via an all-zero summary and the
-  captured traceback is always surfaced.
-
- **Bug Hunt Pool Supervisor Non-Blocking Tracking**: Updated `bug-hunt-pool-supervisor` to make the automation tracking step non-blocking. The `automation-tracking-manager` call in step 5 is now best-effort — if it does not complete within a reasonable time or fails, the supervisor skips it and continues to the next cycle. Added explicit rule 9 clarifying that tracking must never block the main loop. Core functionality (module scanning and worker dispatch) takes priority over status reporting.
-
- **Name Validator Server-Qualified Format** (#9074): Updated actor, skill, and tool name
-  validators to accept the spec-required `[[server:]namespace/]name` format. Previously,
-  server-qualified names like `dev:freemo/custom-analysis` were incorrectly rejected.
-  Added BDD scenarios for server-qualified name acceptance and rejection. All three
-  validators (`ActorConfigSchema.validate_name`, `NAMESPACED_NAME_RE`,
-  `_TOOL_NAME_PATTERN`) now correctly support optional server prefixes while maintaining
-  backward compatibility with existing `namespace/name` names.
-
- **Legacy CLI command removal** (#4181): Removed all legacy plan lifecycle CLI
-  commands (`tell`, `build`, `new`, `current`, `cd`, `continue`) and their
-  associated tests to support V3 Plan Lifecycle exclusively. Removed `tell` and
-  `build` CLI shortcuts from `main.py` that delegated to the deprecated commands.
-  Removed orphaned `_tell_streaming` dead code from `plan.py`. Updated help text
-  and command validation to recognize only V3 commands. Added `--format` option
-  to `agents session tell` for consistency with other session commands. Fixed
-  MCP logger thread-safety in `session.py` using a threading lock. Created
-  migration guide for users transitioning from legacy to V3 workflow.
-
 - **Automation Profile Silent Fallback** (#8232): `_resolve_profile_for_plan` in

 ### Added
-
- **ACMS Index Data Model and File Traversal Engine** (#9579): Implements the
-  foundational ACMS index data model with structured fields for file metadata
-  (path, size, last modified, type), tag system, and hot/warm/cold/archive
-  storage tier assignment. Introduces a timeout-safe large-project file traversal
-  engine capable of handling 10,000+ files without memory exhaustion through

-  storage, and retrieval with full queryability by path, tag, type, and recency.
-
- **ACMS Large-Project Indexing BDD Coverage** (#8726): Added 7 Behave scenarios
-  covering walk-based indexing of 10,000+ files without timeout, binary-file
-  skipping, oversized-file skipping, git-checkout indexing, fallback to walk when
-  `git ls-files` is unavailable on a non-git directory, and total-bytes budget
-  enforcement. Optimised fixture setup to pre-create subdirectories (99x fewer
-  syscalls). Added `timeout=120` to git subprocess calls to prevent CI hangs.
-  Cached `get_scoped_view` results in `When` steps to avoid redundant re-queries
-  in `Then` steps.
-
- **Agent Evolution Pool Supervisor PR Metadata Assignment** (#7888): The
-  agent-evolution-pool-supervisor now automatically looks up the Type/Automation
-  label and the earliest open milestone from the repository before dispatching
-  improvement PR creation workers. Label and milestone IDs are passed to workers
-  via the dispatch context, ensuring all generated improvement PRs have correct
-  Type labels and milestone assignments. Graceful error handling skips label or
-  milestone assignment when either is unavailable. Added comprehensive BDD test
-  suite (7 scenarios) covering label lookup, milestone lookup, worker dispatch,
-  PR creation with metadata, and error handling for missing labels/milestones.
+- **ACMS Hot/Warm/Cold Storage Tiers** (#9580): Implements three-tier storage

+  tracking (O(1) metrics), bounded `LifecyclePolicyEngine` dicts to prevent memory
+  growth, key sanitization via SHA-256 hashing to prevent path traversal, and
+  index rebuild from disk on instantiation for correct restart behavior.

+6. **PlanResult Domain Model — `result_success` column** (migration `m9_003_plan_result_success_column`): The legacy `plans` table includes a dedicated `result_success BOOLEAN NULLABLE` column that explicitly records the success status of the result (apply) phase. `PlanRepository._to_domain` derives `PlanResult.success` from this column rather than from `error_message is None`. The `error_message` column is shared between the build phase and the result phase; using it to infer result success would incorrectly mark plans as failed when a build-phase error was recorded but the apply phase later succeeded. When `result_success` is `NULL` (pre-migration records), the repository falls back to the legacy `error_message is None` heuristic for backward compatibility.

+Feature: TDD Issue #7501 — PlanResult.success derived from result_success column
+  As a system operator managing plan lifecycle
+  I want PlanResult.success to be derived from the dedicated result_success column
+  So that plans with historical build errors are not incorrectly marked as failed
+
+  The root cause is that PlanRepository._to_domain derived PlanResult.success
+  from `error_message is None`. Because error_message is shared between the
+  build phase and the result phase, a plan that had a build error but later
+  succeeded in the apply phase would be incorrectly reconstructed as failed.
+
+  The fix adds a dedicated result_success column to the plans table and updates
+  _to_domain to use it. For backward compatibility, when result_success is NULL
+  (pre-migration records), the legacy heuristic (error_message is None) is used.
+
+  Background:
+    Given a clean in-memory database for plan result success tests
+    And a legacy plan repository backed by the database

+
+  Scenario: Plan with result_success=False is reconstructed as success=False

+Feature: TDD Issue #10414 — session create silently suppresses facade dispatch exceptions without logging
+  As a developer debugging a session creation failure
+  I want exceptions from _facade_dispatch() to be logged at WARNING level
+  So that I can diagnose why the facade layer failed without silent data loss
+
+  The ``session create`` command in
+  ``src/cleveragents/cli/commands/session.py`` previously used
+  ``contextlib.suppress(Exception)`` to silently discard ALL exceptions
+  raised by ``_facade_dispatch()``.  There was no logging call before or
+  after the suppress block, making it impossible to diagnose failures in
+  the facade layer.
+
+  The fix replaces the suppress block with a ``try/except Exception`` that
+  calls ``_log.warning(..., exc_info=True)`` so that the exception is
+  recorded but the session creation remains non-fatal.

+"""Add result_success column to plans table.
+
+This migration adds a dedicated ``result_success`` boolean column to the
+``plans`` table to accurately track the final result status of a plan's
+apply phase.
+
+Previously, ``PlanRepository._to_domain`` derived ``PlanResult.success``
+from ``error_message is None``.  Because ``error_message`` is shared
+between the build phase and the result phase, a plan that encountered a
+build error but later succeeded in the apply phase would be incorrectly
+reconstructed as failed.
+
+The new ``result_success`` column is nullable to preserve backward
+compatibility with existing database records.  When ``result_success``
+is NULL (pre-migration records), the repository falls back to the legacy
+``error_message is None`` heuristic.
