hurui200320 eb770643c2 test(e2e): validate M5 acceptance criteria for v3.4.0 milestone closure
Add four CLI-based integration test cases to the M5 E2E verification suite
that exercise the exact commands from the v3.4.0 milestone description via
real subprocess calls to `python -m cleveragents`.

CLI test cases:
- CLI Project Create Large Project: `agents project create local/large-project`
- CLI Resource Add Git Checkout: `agents resource add git-checkout ...`
- CLI Project Link Resource: `agents project link-resource ...`
- CLI Project Show Displays Linked Resource: `agents project show ...`

Each test creates an isolated temp directory with its own CLEVERAGENTS_HOME,
initialises a workspace via `agents init`, runs the target CLI command as a
subprocess with `on_timeout=kill`, asserts zero exit code and verifies
expected output, then tears down the temp directory.

Bug fix: ProjectResourceLinkRepository.create_link() and remove_link() only
called session.flush() without session.commit(), causing linked resource data
to be silently lost between sessions. Added session.commit() to both methods,
plus finally: session.close() to match the session-factory lifecycle pattern
used by all other mutating repository methods. Added session.refresh() and
session.expunge() before return in create_link() so the returned ORM instance
is fully loaded and usable in detached state after session close.

Regression guard: Added two cross-session persistence Behave scenarios
(project_repository.feature) that open a new session from the same engine
after create_link/remove_link and verify the operation was durably committed.

Test improvements from review feedback (rounds 1 and 2):
- Per-test CLEVERAGENTS_HOME isolation via env: override on all Run Process
  calls to prevent shared state between tests.
- Stronger ULID-based assertions: CLI tests capture the resource_id ULID from
  resource show output and verify the exact ID in project show output.
- Regex-based branch assertion (branch.*main) instead of generic string match.
- Test 4 differentiated from Test 3 by verifying resource show independently
  after linking and asserting the specific resource ULID.
- Documentation noting context tier and ACMS criteria are validated at the
  Python API level via helper_m5_e2e_verification.py.
- Updated ProjectResourceLinkRepository class docstring documenting commit
  and close behaviour of mutating methods.
- CHANGELOG entry for both test additions and production bug fix.
- Redundant Library imports removed, --format plain on project list, comments
  explaining fake repo directories, standardised Run Process line style.

Context/ACMS CLI coverage is intentionally not added because the CLI does not
yet expose dedicated context/ACMS inspection commands. These criteria are
validated at the Python API level via helper_m5_e2e_verification.py.

CoreRasurae 3e3e9b4b5d feat(observability): wire AuditService.record() into domain services via EventBus auto-dispatch
Implements AuditEventSubscriber that subscribes to all 9 security-relevant
EventType members and persists redacted audit entries via AuditService.record().

Key components:
- AuditEventSubscriber: bridges EventBus and AuditService (SEC7)
- SECURITY_EVENT_MAP: maps EventType enum to audit type strings
- Redaction via redact_dict() on event details before persistence
- Graceful error handling: failures logged, never propagated

Post-review fixes applied:
- BUG-1: Remove dead correlation_id null-check guard (DomainEvent.correlation_id
  is always non-None via ULID default_factory)
- SEC-2: Redact exception messages in warning logs via redact_value() to prevent
  potential leakage of sensitive internal state (e.g. DB connection strings)
- PERF-3: Pre-generate unique DomainEvent instances in ASV benchmark setup to
  avoid skew from reusing a single frozen object
- Wire event_bus from the DI container into CorrectionService (plan.py),
  ConfigService (config.py, skill.py x2, server.py), and
  PersistentSessionService (session.py) at their CLI construction sites.

Closes #581

Brent E. Edwards 5e625b22e1 fix(test): convert M1-M6 E2E suites to real subprocess CLI invocations (closes #658)
Replace CliRunner + unittest.mock.patch with subprocess.run for all
21 CLI-facing test functions across the M1-M6 E2E verification helpers.

Application code fixes:
- action.py: _get_lifecycle_service() uses container.plan_lifecycle_service()
- plan.py: _get_lifecycle_service() uses container.plan_lifecycle_service()
- plan.py: three container.resolve(DecisionService) → container.decision_service()

Test infrastructure:
- New robot/helper_e2e_common.py with shared subprocess utilities
  (run_cli, setup_workspace with DB migrations, cleanup_workspace)
- M1-M4, M6 helpers refactored to use run_cli() with real SQLite DB
- M5 unchanged (0 CLI tests, all domain-level)
- TDD detection updated to recognise run_cli() as subprocess invocation
- Remove @tdd_expected_fail from TDD feature + robot tags
- Update 8 Behave step files that mocked container.resolve() to use
  container.decision_service() / container.plan_lifecycle_service()

Luis Mendes c8cd7eab82 feat(testing): implement @tdd_expected_fail tag handling in Behave environment
Implemented the three-tag TDD bug-capture system in Behave environment hooks:

- Added tag validation in before_scenario: @tdd_bug_<N> requires @tdd_bug,
  @tdd_expected_fail requires both @tdd_bug and @tdd_bug_<N>
- Added result inversion via Scenario.run() wrapper installed in before_all:
  scenarios tagged @tdd_expected_fail that fail are reported as passed
  (expected failure), and scenarios that unexpectedly pass are reported as
  failed with guidance to remove the tag
- Added helper functions validate_tdd_tags() and should_invert_result()
- Added inline documentation referencing CONTRIBUTING.md > TDD Bug Test Tags
- Added Behave test scenarios for tag validation and inversion behavior
- Extract apply_tdd_inversion() as a public, testable function that
  encapsulates all inversion logic with proper guards
- Refactored handle_tdd_expected_fail() to delegate to apply_tdd_inversion()
  after tag validation, eliminating ~55 lines of duplicated inversion logic
- Tag validation errors in handle_tdd_expected_fail() are now logged at
  WARNING level instead of being silently swallowed
- Add hook_failed guard: never invert infrastructure/hook errors
- Add was_dry_run guard: skip inversion when no test actually ran
- Add non-AssertionError guard: warn and skip inversion for exceptions
  that likely indicate infrastructure problems, not the captured bug
- Log exception details at DEBUG level before clearing (previously
  discarded silently)
- Attach synthetic AssertionError to last step on unexpected pass so
  the failure reason appears in standard Behave formatter output

Brent E. Edwards 6806ef3620 test(e2e): TDD failing tests for E2E mock-only coverage (bug #658)
Add Behave and Robot Framework TDD tests that use AST analysis to
inspect the M1-M6 E2E verification helper files and prove that all
21 CLI-facing test functions use unittest.mock.patch + CliRunner
instead of exercising the real CLI via subprocess invocation.

The tests verify three properties that currently fail (proving #658):
- At least one CLI-facing test uses subprocess instead of CliRunner
- At least one CLI-facing test exercises the real service layer
- Every suite with CLI tests has at least one unmocked test

Tagged @tdd_expected_fail so the tests pass CI while the bug is
present.  The @tdd_expected_fail tag inverts the result: the tests
pass because the underlying assertions fail (confirming the bug).
Once #658 is fixed, the tag is removed and the tests run normally.

Files added:
- features/tdd_e2e_mock_only_coverage.feature (3 scenarios)
- features/steps/tdd_e2e_mock_only_coverage_steps.py
- robot/tdd_e2e_mock_only_coverage.robot (3 test cases)

brent.edwards e732c32981 fix(cli): handle missing database in session list command
Register PersistentSessionService in the DI Container so that
'agents session list' (and all other session subcommands) no longer
throw AttributeError due to a missing 'db' provider.

Changes:
- Add _build_session_service() factory and session_service provider to
  Container, with targeted table creation for session/session_messages
  only (avoids bypassing Alembic for the full schema).
- Add auto_commit parameter to SessionRepository and
  SessionMessageRepository; when True each method commits and closes
  its own database session, preventing resource leaks in CLI context.
- Rewrite _get_session_service() to resolve via container.session_service()
  with module-level caching.
- Add (DatabaseError, AttributeError) error handling with logging to all
  seven session subcommands (list, create, show, delete, export, import,
  tell).
- Remove @tdd_expected_fail tags from all session test files so they run
  as proper regression tests.

freemo ec0b7631d0 refactor(a2a): rename ACP module and symbols to A2A standard
Renamed src/cleveragents/acp/ to src/cleveragents/a2a/ and all 13
Acp* classes to A2a* per ADR-047 (A2A Standard Adoption). Updated
all imports, structlog event names (acp.* → a2a.*), field names

CoreRasurae 7ac3f1352c feat(devcontainer): add container-aware tool execution and I/O forwarding
Implement ContainerToolExecutor for delegating tool invocations to
devcontainer environments with full I/O forwarding. Add PathMapper for
bidirectional host/container path translation. Wire container routing
into ToolRunner with graceful fallback when no executor is configured.
Add container_metadata field to ToolInvocation for tracking execution
context.

New modules:
- tool/container_executor.py: ContainerToolExecutor, ContainerConfig,
  ContainerMetadata, ContainerExecutionError, ContainerTimeoutError
- tool/path_mapper.py: PathMapper with host_to_container/container_to_host

Modified:
- tool/runner.py: container execution routing via ExecutionEnvironment
- domain/models/core/change.py: container_metadata on ToolInvocation
- tool/__init__.py: new public exports

Review fixes applied:
- Add Alembic migration m6_004 for container_metadata_json column
- Enforce _MAX_OUTPUT_BYTES (50 MiB) truncation in _run_command()
- Fix path traversal in sync_results_to_host (Path.is_relative_to)
- Allow spaces in _looks_like_path() for valid filesystem paths
- Preserve negative exit codes from signal kills in metadata
- Add default=str to json.dumps(invocation.arguments) safety net
- Log warnings when path mapping recursion depth exceeded
- Warn when devcontainer binary not found on PATH
- Use default allow_nan for host-path JSON validation in runner.py
  (only container path requires RFC 7159 strict mode)
- Reject URL-like patterns in _looks_like_path() to avoid false
  positives on API routes, protocol-relative URIs, and query strings
- Add extract_container_metadata() static helper on
  ContainerToolExecutor as bridge for ToolInvocation wiring
- Use raw_stdout bytes in sync_results_to_host to prevent
  binary file corruption from text-mode decode/re-encode
- Apply posixpath.normpath() in workspace_folder validator and
  reject path components containing '..'
- Check result.timed_out in sync_results_to_host and raise
  ContainerTimeoutError instead of always raising ContainerExecutionError
- Detect overlapping host_root/container_root in PathMapper and
  raise ValueError to prevent corrupt bidirectional mappings
- Wrap host-side I/O in sync_results_to_host with try/except
  OSError to produce ContainerExecutionError on write failure
- Enforce int(timeout) in _build_exec_command to prevent shell
  injection via malicious objects with __str__ methods
- Change ToolResult validator from 'not self.error' to
  'self.error is None' so empty-string errors are accepted
- Iterate required list directly in ToolRunner schema validation
  to detect fields listed in required but absent from properties

hamza.khyari 1e606553d4 feat(acms): implement Real-time Index Sync / UKOIndexer with pluggable analyzers
Implement the UKOIndexer service that produces UKO triples from resources
using pluggable domain-specific analyzers, wraps each triple with provenance
metadata, and simultaneously indexes into text, vector, and graph backends.

Key design decisions and components:

- UKOIndexer orchestrates the full index lifecycle: add_resource,
  update_resource (remove-then-add), remove_resource, and maintenance
  triggers. Each operation fires lifecycle hooks (on_indexed, on_removed,
  on_error) so callers can observe progress.

- Analyzer selection is pluggable via ContentAnalyzer protocol. The indexer
  accepts a registry mapping resource types to analyzers. PythonAnalyzer
  and MarkdownAnalyzer are provided as built-in implementations.

- LocationContentReader protocol abstracts file I/O with a base_dir
  parameter for path-traversal prevention (post-resolve validation rejects
  paths escaping the base directory and non-regular files).

- UKOTriple model includes a @model_validator ensuring at least one of
  object_uri or object_value is populated, preventing empty triples at
  construction time.

- Triple removal uses scoped deletion via uko:sourceResource predicate to
  avoid shared-subject collision — only triples originating from the
  specific resource are removed, not all triples for a shared subject.

- _resource_subjects.pop is deferred until after all backend removal
  operations succeed, preventing inconsistent state on partial failure.

- analyzer.analyze() is wrapped in try/except so that analyzer errors
  produce an IndexResult with error details rather than propagating
  exceptions to callers.

- All lifecycle hook calls are guarded via _fire_on_indexed,
  _fire_on_removed, and _fire_on_error helpers that catch and log hook
  exceptions without disrupting the indexing pipeline.

- max_triples parameter (default 50,000) bounds analyzer output size to
  prevent runaway resource consumption.

- ResourceFileWatcher monitors filesystem paths via watchdog and triggers
  re-indexing callbacks on file changes with configurable debouncing.
  Emits RESOURCE_MODIFIED domain events via EventBus when file changes
  are detected. Debounce timers coalesce rapid edits into a single
  callback invocation. Thread-safe design with daemon threads for clean
  shutdown.

- SearchResult.__post_init__ validates score is in [0.0, 1.0], correctly
  rejecting NaN values.

- Placeholder embedding uses [1.0] instead of [float(len(content))] to
  avoid leaking content size information.

- isinstance check on graph_backend ensures GraphIndexBackend protocol
  compliance at runtime.

- Test doubles extracted to features/mocks/uko_indexer_mocks.py for reuse
  across BDD steps and Robot helpers.

Brent E. Edwards 73d5552467 fix(actor): handle empty actor list without validation error
ActorRegistry._actor_name() built names via f"{provider}/{model}", which
produced names with multiple slashes when providers included models
containing "/" (e.g. OpenRouter's "anthropic/claude-sonnet-4-20250514").
The resulting name violated the spec pattern ^[a-z0-9_-]+/[a-z0-9_-]+$
and triggered a ValidationError during actor upsert.

Now sanitises both provider and model components by replacing "/" with "-"
and lowercasing, so multi-slash provider models no longer break actor
listing.

Includes 6 Behave BDD regression scenarios (covering zero-provider,
multi-slash, consecutive-slash, leading-slash, and name-validation
cases), Robot Framework integration smoke tests, and ASV benchmarks.

brent.edwards 4fff7f67c5 fix(test): use scoped_session to prevent GC-induced data loss in r2cov
SQLite in-memory engines use SingletonThreadPool, giving every Session
the same underlying connection.  Repository methods create a new
Session via the factory, flush, then return — letting the Session go
out of scope.  Under high memory pressure (e.g. 32 parallel behave
workers) Python's garbage collector closes these orphaned Sessions,
issuing an implicit ROLLBACK on the shared connection and wiping
flushed-but-uncommitted rows written by other Sessions.

Replace the plain sessionmaker with scoped_session in the r2cov
Background step so that every factory() call returns the same Session
instance.  A single long-lived Session per scenario eliminates the
premature close/rollback window entirely.

Verified: 3 consecutive green runs with --processes 32 (10 099
scenarios, 0 failures each).

Brent E. Edwards d0689573e0 test(cli): add failing tests for session create DI container error
Add TDD regression tests for bug #570 where `_get_session_service()`
calls `container.db()` but the DI `Container` class has no `db`
provider, raising `AttributeError`.  Same root cause as bug #554.

Includes 4 Behave BDD scenarios tagged `@tdd_bug @tdd_bug_570
@tdd_expected_fail`, Robot Framework integration smoke tests with
`--format plain`, and ASV service-layer benchmarks.  Tests exercise the
real DI path by resetting `_service = None` and using a file-based
SQLite database.

Implements the `@tdd_expected_fail` inversion infrastructure:
- Behave: `after_scenario` hook in `features/environment.py` inverts
  pass/fail for scenarios tagged `@tdd_expected_fail`
- Robot: `robot/tdd_expected_fail_listener.py` listener (API v3)
  performs the same inversion for Robot test cases
- `noxfile.py`: registers the listener via `--listener` in both the
  `integration_tests` and `slow_integration_tests` sessions

Migrates 18 existing TDD scenarios across 5 feature files from the old
`@tdd @bugNNN` convention to the standardised `@tdd_bug @tdd_bug_NNN`
tags per CONTRIBUTING.md § TDD Bug Test Tags.

Brent E. Edwards 4c5589da4e test(cli): add failing TDD tests for session list DI container error
Add 10 Behave BDD scenarios (@tdd_bug @tdd_bug_554 @tdd_expected_fail)
for the session list DI wiring bug where _get_session_service() calls
container.db() but the Container has no db provider (AttributeError).
Scenarios cover empty list, format validation (JSON/YAML/plain/rich),
init-then-list lifecycle, and post-create list paths.

Implement @tdd_expected_fail infrastructure: Behave after_scenario hook
inverts FAIL→PASS (expected) and PASS→FAIL (unexpected fix), plus Robot
Framework listener (Listener API v3) with identical semantics registered
via --listener in both integration_tests and slow_integration_tests nox
sessions.

Migrate 18 existing TDD scenarios across 5 feature files from legacy
@tdd @bugNNN convention to @tdd_bug @tdd_bug_NNN per CONTRIBUTING.md
§ TDD Bug Test Tags.

Includes Robot Framework integration smoke tests and ASV service-layer
benchmarks.

brent.edwards 06bbe48a9c test(session): add TDD failing tests for session list DI error
Implement TDD bug-capture tests for bug #554 where `agents session list`
fails because `_get_session_service()` calls `container.db()` which does
not exist on the DI Container class (AttributeError).

Behave BDD scenarios tagged @tdd_bug @tdd_bug_554 @tdd_expected_fail
exercise the real DI path (no mocks) and assert correct behavior. The
@tdd_expected_fail handler in environment.py inverts failed→passed while
the bug is present, keeping CI green.

Also adds:
- @tdd_expected_fail infrastructure in features/environment.py
  (tag validation + status inversion in after_scenario hook)
- behave-parallel exit logic fix to use summary-based failure
  detection (compatible with TDD status inversion)
- Robot Framework integration smoke tests with self-inverting helper
- ASV benchmark baseline for session list command throughput

freemo 876217d0ca feat(guardrails): implement Per-Session and Per-Org Cost Budgets
Implements Forgejo issue #584: three-tier budget hierarchy
(per-plan -> per-session -> per-org) with tightest limit winning.

Domain models:
- BudgetLevel enum (PLAN, SESSION, ORG)
- BudgetCheckResult (frozen Pydantic model with exceeded_level, warning)
- SessionCostBudget (tracks per-session accumulated cost)
- OrgCostAccumulator (tracks per-org accumulated cost)
- ThreadSafeOrgCostAccumulator (thread-safe wrapper with snapshot)

Application services:
- CostBudgetService: manages budget state, enforces hierarchy,
  emits BUDGET_WARNING (once per session) and BUDGET_EXCEEDED events
- AutonomyGuardrailService: extended with associate_plan_with_session,
  check_budget_hierarchy, record_plan_cost_to_session methods

Configuration:
- Settings: session_max_cost_usd, org_max_cost_usd, budget_warning_threshold

Integration:
- Session model: cost_budget field, as_cli_dict includes budget data
- DI container: CostBudgetService registered as Singleton
- CLI session show: cost budget panel display

Tests:
- 54 Behave scenarios (features/cost_budgets.feature)
- 11 Robot Framework integration tests (robot/cost_budgets.robot)
- ASV benchmarks (benchmarks/bench_budget_check.py)

All nox stages pass: lint, typecheck, unit_tests, coverage_report (98%).

freemo 958eb0c060 feat(observability): implement Metrics Collection Framework (14 metric types with Histogram/Counter/Gauge)
Implement the structured metrics collection framework covering 14
operational metric types with proper Histogram, Counter, and Gauge
semantics per the spec (Architecture > Observability > Metrics
Collection, lines ~43805-43825).

Domain layer:
- Add MetricType enum (HISTOGRAM, COUNTER, GAUGE) to metrics.py
- Add MetricDefinition model and METRIC_DEFINITIONS registry mapping
  all 14 OperationalMetricKey values to their metric types
- Extend MetricCollector with typed factory methods (histogram, counter,
  gauge) and 14 convenience methods (plan_duration, plan_cost,
  plan_decision_count, subplan_count, actor_invocation_count,
  actor_latency, tool_invocation_count, tool_error_rate,
  context_build_time, context_token_count, llm_call_count,
  llm_total_tokens, llm_total_cost, llm_avg_latency)
- Extend MetricEntry with optional metric_type field that auto-resolves
  from METRIC_DEFINITIONS via MetricCollector.record()

Infrastructure layer:
- Add MetricsEmitter (infrastructure/observability/metrics_emitter.py)
  with emit(), emit_batch(), from_settings(), and enabled/disabled
  support for structured log emission in local mode
- Add metrics_log_processor (config/metrics_processor.py) for structlog
  integration

Configuration:
- Add metrics_enabled and metrics_export_prometheus settings
- Register MetricsEmitter as DI Singleton in application container

Instrumentation:
- Add best-effort metric emission in PlanExecutor for plan_duration
  (both runtime and stub execute paths) and plan_decision_count
  (strategize path) via _try_emit_metric helper that tolerates invalid
  plan IDs in test fixtures

Testing:
- 34 Behave BDD scenarios (features/observability/metrics_collection.feature)
- 8 Robot Framework integration tests (robot/metrics_collection.robot)
- ASV benchmark suite (benchmarks/bench_metrics_collection.py)

components through module:ClassName resolution and entry point discovery.

Key changes:
- Add infrastructure/plugins/ package with PluginLoader, PluginManager, types, exceptions
- Implement dynamic import via module:ClassName with security prefix allowlist
- Add entry point discovery via importlib.metadata
- Add Protocol validation for loaded plugin classes
- Add plugin lifecycle management (discover/activate/deactivate)

CoreRasurae cf67ba0a86 feat(devcontainer): add lazy activation and lifecycle management
Implemented lazy container activation for devcontainer-instance resources
with ContainerLifecycleState enum tracking six states (inactive, starting,
active, stopping, stopped, error) with validated transitions. Extended
DevcontainerHandler with devcontainer up CLI integration and JSON output
parsing for container start. Added periodic health checking via
devcontainer exec ping with configurable interval. Added agents resource
stop and agents resource rebuild CLI commands for manual lifecycle
control. Wired session close and plan completion hooks to automatic
container cleanup. Includes lifecycle state persistence in resource
registry with timestamped transitions. Added Behave BDD tests, Robot
integration tests, and ASV activation latency benchmarks.

- Added remoteWorkspaceFolder absolute-path validation
- Aligned spec: handler name, rebuild types, --yes flag on stop/rebuild
- Added registry re-read in stop_container success path for consistency
- Added session_id field to ContainerLifecycleTracker for scoped cleanup
- Scoped stop_all_active_containers to session_id when provided
- Wired _cleanup_devcontainers into fail_apply and fail_execute
- Wired start_health_check into activate_container success path
- Restructured facade session close to always run container cleanup
  even without session service (F4)
- Re-read tracker from registry in activate_container success path
- Added evict_terminal_trackers to cap registry growth
- Updated devcontainer_resources.md: health check auto-start, scoped
  cleanup hooks, known limitations for eviction and sandbox_strategy
- Wired evict_terminal_trackers into stop_all_active_containers so
  terminal-state trackers are actually evicted in production
- Made stop_container idempotent: returns early when container is
  already in a terminal state instead of raising ValueError
- Fixed benchmark health check thread leak in TimeActivationLatency
  by clearing registry after each timing loop
- Added rebuild pass-through (--reset-container flag to devcontainer up)
- Added host_workspace_path field on ContainerLifecycleTracker so
  health probes use the host-side path for devcontainer exec
- Wired lazy activation into DevcontainerHandler.resolve() for
  devcontainer-instance resources in non-running states
- Changed _default_strategy from SNAPSHOT to NONE (container
  itself provides isolation; SandboxFactory raises NotImplementedError
  for snapshot)
- Restricted _STOPPABLE_TYPES to devcontainer-instance only
  (container-instance is not directly stoppable via CLI)

hamza.khyari 23d8a53f6a fix(resource): address review findings for resource type inheritance
Fix 25 of 27 review findings from PR #618 code review:

P1 (Must Fix):
- F3: Fix silent data corruption in _merge_collection for properties
  dict fields (was falling through to string list merge)
- F1: Split 1023-line step file into 3 files + helper module (all <500)
- F4: Add SELECT FOR UPDATE lock on parent type in register_type to
  prevent TOCTOU race in concurrent registrations
- F6: Fix docs claiming exceptions inherit from CleverAgentsError
  (they inherit from ValueError)
- F7: Fix docs incorrectly describing validate_chain return type

P2 (Should Fix):
- F9: Replace dict[str, Any] with TypeRegistryMap type alias
- F10: Replace import logging with structlog in inheritance.py
- F11: Add __all__ to inheritance.py
- F13: Fix _load_type_registry to derive built_in from namespace column
- F14: Add warning log for unregistered types in resolve_inheritance_chain
- F15: Return defensive copies from resolve_fields
- F16: Add chain validation to bootstrap_builtin_types
- F17: Narrow except Exception to specific types in step files
- F18: Add side-effect verification scenarios after error cases
- F19: Always include inherits key in JSON output for consistent schema
- F20: Log actual exception instead of hardcoded string in CLI

P3 (Nit):
- F21: Reject whitespace-only inherits values in validate_chain
- F23: Wrap chain errors in HandlerResolutionError in resolver
- F24: Return defensive copies from as_cli_dict
- F25: Replace tautological assertion with ResourceHandler isinstance
- F26: Add whitespace inherits test scenario
- F27: Fix find_subtypes docstring to note it excludes ancestor_name

Deferred:
- F2: type: ignore in step files — pyright only checks src/, matches
  existing project pattern (91 occurrences in resource_dag_steps.py)
- F5: CLI integration tests require full DI container setup
- F8: resource_registry_service.py size is pre-existing (971 on master)
- F12: Coverage boost file changes are test adaptations, not scope creep
- F22: FK constraint intentionally omitted per docs (SQLite compat)

brent.edwards 16dc4ab18d fix(project): show created project after creation (#593)
## Summary

Fix `agents project show` not finding a project immediately after creation. Extends the `session.commit()` fix from #589 to also cover `update()` and `delete()` in `NamespacedProjectRepository`.

## Changes

**Production fix** (`src/cleveragents/infrastructure/database/repositories.py`):
- Add `session.commit()` to `create()`, `update()`, and `delete()` methods
- Add `finally: session.close()` guard to all three methods
- Update class docstring to reflect commit-per-method pattern

**Tests & benchmarks**:
- 3 Behave BDD regression scenarios (`features/project_show_after_create.feature`)
- Robot Framework integration smoke tests with "not found" assertion (`robot/project_show_after_create.robot`)
- ASV benchmarks for create-then-show round-trip (`benchmarks/project_show_after_create_bench.py`)

## Review feedback addressed

- **F1**: Removed unrelated em-dash CHANGELOG edits — wrote clean entry from scratch
- **F2**: Kept Suite Setup/Teardown (required for `${PYTHON}` variable); updated stale docs
- **F3**: Added "not found" string assertion to Robot negative test case
- **F4**: Removed redundant `Base.metadata.create_all()` from `_make_fresh_repo()` helper
- Updated all stale TDD "expected to fail" comments — this PR includes the fix

## Process

- Single squashed commit, rebased onto `master` (no merge commits)
- Prescribed commit message from issue #590 metadata

brent.edwards 26de6bb7de fix(project): persist project to database during creation (#591)
## Summary

Fix `agents project create` not persisting projects to the database. `NamespacedProjectRepository.create()` called `session.flush()` but never `session.commit()`, so projects were invisible to subsequent `agents project list` invocations that open a separate session.

## Changes

**Production fix** (`src/cleveragents/infrastructure/database/repositories.py`):
- Replace `session.flush()` with `session.commit()` in `NamespacedProjectRepository.create()`
- Add `finally: session.close()` guard for proper session lifecycle

**Tests & benchmarks**:
- 4 Behave BDD regression scenarios (`features/project_create_persist.feature`)
- Robot Framework integration smoke tests (`robot/project_create_persist.robot`)
- ASV benchmarks for create-then-list round-trip (`benchmarks/project_create_persist_bench.py`)

## Review feedback addressed

- **H3**: Added `finally: session.close()` to `create()` method
- **M1**: Removed redundant `session.flush()` before `session.commit()`
- **M2**: Updated stale TDD "expected to fail" comments — this PR includes the fix
- **M4**: Rewrote CHANGELOG entry to describe the fix, not just tests
- **F1**: Updated Robot documentation (Suite Setup/Teardown kept — needed for `${PYTHON}`)
- **F2**: Fixed bare assertion `"my-app"` to `"local/my-app"` in namespace scenario
- **F3**: Removed redundant `Base.metadata.create_all()` from `_make_fresh_repo()`
