Add 3 deferred virtual resource types (remote, submodule, symlink) with
equivalence metadata for physical-to-virtual resource linking.
Depends on: #662 (child_types reference types introduced by #662)
- Type definitions extracted to _resource_registry_virtual_deferred.py
for consistency with _resource_registry_virtual.py (#329)
- YAML configs with equivalence criteria per spec, spec reference comments
- Bootstrap registration via BUILTIN_TYPES spread, hidden from
resource add scaffolding (user_addable: false)
- Equivalence structural validation in ResourceTypeSpec model validator:
criteria must be a non-empty list of non-empty strings; virtual types
must have sandbox_strategy=none, user_addable=false, handler=None,
all capabilities false
- Behave tests (52 scenarios), Robot tests (7), ASV benchmarks
- DB roundtrip tests verifying virtual types survive bootstrap persistence
- Negative tests: missing equivalence/name/kind, manual add rejection
for all 3 virtual types (register_resource guard), invalid criteria
elements (non-string, empty string)

_get_plan_executor() created a second PlanLifecycleService Factory
instance with its own in-memory _plans cache. After the executor's
run_strategize() advanced the plan to execute/queued (via
auto_progress), the CLI handler's separate service instance returned
stale strategize/queued state from its cache, causing spurious
"Plan is not in an executable state" errors.
Fix: _get_plan_executor() now accepts an optional lifecycle_service
parameter; the plan execute handler passes its own service instance so
both share the same cache.
Also addressed review feedback:
- Improved type safety: lifecycle_service parameter typed as
PlanLifecycleService | None instead of Any | None.
- Added BDD regression test verifying the lifecycle service is shared
between the CLI handler and the executor.
- Updated reference documentation to reflect the type annotation change.

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

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

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

Closes#313
Restructure the TUI specification from a nested subsection under
"Behavior > UI / Interaction Model" to a top-level "## TUI" section,
giving it equal standing with Core Concepts, Behavior, Configuration,
and Architecture. All headings within the TUI section are promoted one
level (#### → ###, ##### → ####).
Fix mkdocs build nav warnings by adding ADR-044/045/046 to the
mkdocs.yml nav and registering three missing reference pages
(acms_fusion, context_indexing, resource_type_inheritance) in the
gen_ref_pages.py nav builder.
Add the complete TUI (Terminal User Interface) specification section to
docs/specification.md, covering architecture, layout, navigation, persona
system, reference picker, slash commands, shell mode, session management,
and keyboard shortcuts. The section includes 18 HTML-styled ASCII mockup
diagrams using the Dracula color palette that render with actual colors
in MkDocs.
Key specification areas:
- MainScreen layout with right-side collapsible sidebar (3 states:
hidden, visible, fullscreen cycled by shift+tab)
- Direct-to-chat launch with first-run actor selection overlay
- Persona system bundling actor + arguments + project/plan scope,
cycled with tab; argument presets cycled with ctrl+tab
- @ reference picker with fuzzy search for projects/plans/resources
- / slash commands mirroring CLI noun:verb patterns (session:new,
plan:list, project:show, actor:switch, etc.)
- ! shell mode for direct command execution
- Multi-session tabs with independent personas and conversations
- Escape-cascading navigation back to main screen
- Plan detail view with decision tree navigation
- Project detail view with resource DAG
- Permission approval workflow with diff view
- Complete keyboard shortcut reference table
New ADR files:
- ADR-044: TUI Architecture and Framework (Textual >= 1.0)
- ADR-045: TUI Persona System
- ADR-046: TUI Reference and Command System (CLI-aligned commands)
Also adds TUI mockup CSS classes to docs/stylesheets/extra.css for
Dracula-palette diagram rendering (.tui-primary, .tui-secondary,
.tui-success, .tui-warning, .tui-error, .tui-dim, .tui-bold,
.tui-bold-primary, .tui-bold-warning, .tui-primary-u, .tui-rainbow).
Temporal metadata fields (validFrom, validUntil, isCurrent, isRevisionOf)
on UKO InformationUnit nodes enable revision chain tracking: when code
changes, old nodes are marked historical and new revision nodes are
created with back-links. Three storage tiers (hot/warm/cold) filter
nodes by temporal scope (current/recent/all) with configurable retention
(warm_retention_hours default 24h, cold_retention_days default 90d).
Includes TemporalMetadata, TemporalNode, RevisionChain, TierQueryResult,
TierRetentionConfig frozen domain models, TemporalBackend protocol,
InMemoryTemporalBackend stub, TemporalService with structlog and DI,
BackendSet.temporal typing upgrade from object|None to TemporalBackend|None.
67 Behave scenarios, 8 Robot Framework tests, ASV benchmarks, and
reference documentation.

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.

Three-pronged fix for intermittent pabot-parallel race condition in
M4 validation integration tests:
1. Composable Setup Database Isolation keyword in common.resource
gives each suite a unique CLEVERAGENTS_DATABASE_URL so concurrent
pabot workers never contend on the same SQLite file.
2. Per-suite CLEVERAGENTS_HOME directories prevent shared temp
directory cleanup from racing between workers.
3. Centralised reset_global_state() in robot/helpers_common.py clears
Settings singleton, DI container, provider registry, and engine
cache between chained CLI invocations in helper processes.
Also:
- Setup Test Environment now accepts optional mock_ai and
auto_apply_migrations arguments (default TRUE) for backward
compatibility while allowing suites to opt out.
- Added Suite Teardown to cli_plan_context_commands.robot.
- Fixed _COMMANDS typing in two helpers to eliminate type: ignore.
- Updated docs/development/testing.md to reflect helpers_common
delegation pattern.
- Added timeout=30s to all Run Process calls in
m4_e2e_verification.robot.

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)

Core domain types (FragmentProvenance, ContextFragment, ContextBudget,
ContextPayload) now extend their CRP counterparts via Pydantic v2
inheritance, ensuring isinstance compatibility across the model
hierarchy.
Key changes:
- CRP base types made frozen=True (no consumer mutates them)
- CRP AssembledContext fields changed from list to tuple (frozen consistency)
- Core types extend CRP bases: FragmentProvenance(CRPFragmentProvenance),
ContextFragment(CRPContextFragment), ContextBudget(CRPContextBudget),
ContextPayload(CRPAssembledContext)
- Removed duplicate ContextFragment dataclass from skeleton_compressor
- Updated project_context.py to pass tuples to frozen AssembledContext
- Added Behave tests (10 scenarios), Robot integration tests (3 cases),
and ASV benchmarks for the unified hierarchy
- Updated Known Limitations table in docs/reference/acms.md
ISSUES CLOSED: #569
- Add AsyncJob domain model with status state machine and Pydantic validation
- Add AsyncWorker service with configurable concurrency and job store
- Add CancellationToken, WorkerHealthReport, InMemoryJobStore
- Add AsyncJobModel SQLAlchemy model and Alembic migration (m6_003)
- Add 5 async config keys to Settings (worker_id, concurrency, poll_interval, max_retries, timeout)
- Add _check_async_worker_health diagnostic check in system.py
- Add comprehensive Behave BDD tests (~60 scenarios) with full step definitions
- Add Robot Framework integration tests (6 smoke tests)
- Add ASV benchmark suite for async execution
- Add architecture documentation
- Update vulture_whitelist with new public API symbols
- All quality gates pass: lint, typecheck, unit_tests, integration_tests, coverage_report (97%)
1. Wire async job creation into PlanLifecycleService:
- Add optional job_store parameter to __init__
- Add _maybe_enqueue_async_job() helper that checks settings.async_enabled
and job store presence before creating and enqueuing an AsyncJob
- Call helper from execute_plan() (phase="execute") and apply_plan()
(phase="apply") after phase transitions
- When async is disabled or no job store is configured, behaviour is
unchanged (silent no-op)
2. Redact secrets in failed job error messages:
- Apply shared.redaction.redact_value() to the error string before
persisting to AsyncJob.error_message, preventing accidental secret
leakage (e.g. API keys in exception text) into the audit trail
Documentation:
- S1: Added specification reconciliation note (ADR-style) to
