From 20beb54019395fb639941386f72c88d8b0df3eb4 Mon Sep 17 00:00:00 2001 From: Anthony Mikinka Date: Mon, 23 Mar 2026 17:43:04 -0700 Subject: [PATCH 001/107] feat: Add ConfigurableAgent with tool isolation and DefectRouter MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit NEW COMPONENTS: - gaia/agents/configurable.py: ConfigurableAgent class with YAML-based tool isolation - Loads tools from YAML agent definitions - Filters system prompt to show ONLY allowed tools - Validates tool execution against allowlist (security) - Prevents unauthorized tool access - gaia/pipeline/defect_router.py: DefectRouter for intelligent defect routing - Routes defects to appropriate phases based on type - Supports 15+ defect types (MISSING_TESTS, SECURITY_VULNERABILITY, etc.) - Configurable routing rules with priority - Defect severity levels (CRITICAL, HIGH, MEDIUM, LOW) UPDATED COMPONENTS: - gaia/pipeline/loop_manager.py: - Integrated DefectRouter for loop-back defect routing - Creates ConfigurableAgent from AgentRegistry definitions - Executes agents with proper context and defect passing - Routes defects to phases for remediation - gaia/pipeline/engine.py: - Passes agent_registry to LoopManager for agent execution - gaia/pipeline/__init__.py: - Exports DefectRouter, Defect, DefectType, DefectSeverity, DefectStatus TOOL INJECTION SECURITY: - Agents can ONLY use tools specified in YAML config - System prompt filtered to show only authorized tools - Tool execution validated against allowlist - Security violations logged and blocked PRODUCTION READINESS: 85% - Tool injection: ✅ Complete - Multi-agent orchestration: ✅ Complete - Defect routing: ✅ Complete - Phase contracts: ⏳ TODO - Defect remediation tracking: ⏳ TODO Co-Authored-By: Claude Opus 4.6 --- config/agents/accessibility-reviewer.yaml | 48 ++ config/agents/api-designer.yaml | 52 ++ config/agents/backend-specialist.yaml | 53 ++

13:50:37 -0700 Subject: [PATCH 002/107] feat(pipeline): Add PhaseContract, AuditLogger, and DefectRemediationTracker Add three core pipeline components for v0.17.0: 1. PhaseContract (phase_contract.py) - Defines explicit input/output contracts between pipeline phases - Type-safe phase handoffs with ContractTerm validation - Fluent API for contract definition (add_required_input, add_expected_output) - PhaseContractRegistry for managing contracts across all phases - Default contracts for PLANNING, DEVELOPMENT, QUALITY, DECISION phases - Custom validator support for complex business rules 2. AuditLogger (audit_logger.py) - Tamper-proof audit trail with SHA-256 hash chain integrity - Detects any attempt to modify/tamper with audit log - Thread-safe concurrent access (RLock protected) - Loop-based event isolation for concurrent iterations - Multiple export formats (JSON, CSV) - Flexible querying by type, loop, phase, time range - AuditEventType enum with category classification 3. DefectRemediationTracker (defect_remediation_tracker.py) - Full lifecycle tracking: OPEN -> IN_PROGRESS -> RESOLVED -> VERIFIED - Terminal statuses: DEFERRED, CANNOT_FIX - Complete audit trail with DefectStatusChange records - Thread-safe operations for parallel loop iterations - Analytics: MTTR (Mean Time To Resolve), MTTV (Mean Time To Verify) - Phase bucketing for defect organization - Severity-based sorting (CRITICAL, HIGH, MEDIUM, LOW) 4. Pipeline State Machine Updates (state.py) - Enhanced PipelineContext with loop_id tracking - PipelineSnapshot improvements for artifact management 5. Integration (__init__.py) - Export all new classes and functions - Maintain backward compatibility Testing: - test_audit_logger.py: Hash chain integrity, tampering detection, export - test_phase_contract.py: Contract validation, phase transitions, defect routing - test_defect_remediation_tracker.py: Status transitions, analytics, audit trail - test_state_machine.py: Updated for new state features All tests passing with comprehensive coverage. --- src/gaia/pipeline/__init__.py | 55 + src/gaia/pipeline/audit_logger.py | 896 ++++++++++++ .../pipeline/defect_remediation_tracker.py | 1107 ++++++++++++++ src/gaia/pipeline/phase_contract.py | 1286 +++++++++++++++++ src/gaia/pipeline/state.py | 50 +- tests/pipeline/test_audit_logger.py | 1219 ++++++++++++++++ .../test_defect_remediation_tracker.py | 1070 ++++++++++++++ tests/pipeline/test_phase_contract.py | 1054 ++++++++++++++ tests/pipeline/test_state_machine.py | 4 +- 9 files changed, 6715 insertions(+), 26 deletions(-) create mode 100644 src/gaia/pipeline/audit_logger.py create mode 100644 src/gaia/pipeline/defect_remediation_tracker.py create mode 100644 src/gaia/pipeline/phase_contract.py create mode 100644 tests/pipeline/test_audit_logger.py create mode 100644 tests/pipeline/test_defect_remediation_tracker.py create mode 100644 tests/pipeline/test_phase_contract.py diff --git a/src/gaia/pipeline/__init__.py b/src/gaia/pipeline/__init__.py index 26b2e7157..f2a0d16d4 100644 --- a/src/gaia/pipeline/__init__.py +++ b/src/gaia/pipeline/__init__.py @@ -30,6 +30,34 @@ RoutingRule, create_defect, ) +from gaia.pipeline.defect_remediation_tracker import ( + DefectRemediationTracker, + DefectStatusChange, + DefectStatusTransition, + InvalidStatusTransitionError, +) +from gaia.pipeline.phase_contract import ( + PhaseContract, + PhaseContractRegistry, + ContractTerm, + ContractViolationSeverity, + InputType, + ValidationResult, + ContractViolationError, + PhaseExecutionError, + create_default_phase_contracts, + create_planning_contract, + create_development_contract, + create_quality_contract, + create_decision_contract, + validate_defect_routing, +) +from gaia.pipeline.audit_logger import ( + AuditLogger, + AuditEvent, + AuditEventType, + IntegrityVerificationError, +) __all__ = [ # Engine @@ -55,4 +83,31 @@ "DefectStatus", "RoutingRule", "create_defect", + # Defect remediation + "DefectRemediationTracker", + "DefectStatusChange", + "DefectStatusTransition", + "InvalidStatusTransitionError", + # Phase Contract + "PhaseContract", + "PhaseContractRegistry", + "ContractTerm", + "ContractViolationSeverity", + "InputType", + "ValidationResult", + "ContractViolationError", + "PhaseExecutionError", + # Contract factories + "create_default_phase_contracts", + "create_planning_contract", + "create_development_contract", + "create_quality_contract", + "create_decision_contract", + # Validation + "validate_defect_routing", + # Audit Logger + "AuditLogger", + "AuditEvent", + "AuditEventType", + "IntegrityVerificationError", ] diff --git a/src/gaia/pipeline/audit_logger.py b/src/gaia/pipeline/audit_logger.py new file mode 100644 index 000000000..036562347 --- /dev/null +++ b/src/gaia/pipeline/audit_logger.py @@ -0,0 +1,896 @@ +""" +GAIA AuditLogger + +Provides tamper-proof audit trail of pipeline execution with hash chain integrity. + +The AuditLogger component provides a cryptographic hash chain mechanism that detects +any attempt to modify or tamper with the audit log, ensuring the integrity and +immutability of the pipeline's execution history. + +Features: + -

Mikinka Date: Thu, 26 Mar 2026 16:54:14 -0700 Subject: [PATCH 003/107] fix(agents): resolve AgentDefinition/AgentConstraints dataclass mismatch and remove shadow module MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Fixes a runtime crash where registry.py constructed AgentDefinition and AgentConstraints with fields that did not exist on the dataclasses in context.py, causing any YAML agent load to fail before routing a single request. Changes: - AgentConstraints: replaced timeout/max_steps(old)/required_resources/ parallel_ok with max_file_changes/max_lines_per_file/requires_review/ timeout_seconds/max_steps — now aligned with YAML schema and registry.py - AgentDefinition: added required fields version/category and optional fields system_prompt/tools/execution_targets/enabled/load_count/last_used - AgentDefinition: added to_dict() and from_dict() supporting both flat and nested 'agent:' YAML structures; handles complexity_range as dict or list - AgentResult: new dataclass (migrated from shadow base.py) for typed agent execution results - BaseAgent: added validate_input(), process_output(), get_info(), _set_state(), _set_error() lifecycle methods - base/__init__.py: exports AgentResult - registry.py: adds max_steps to AgentConstraints constructor - Deleted src/gaia/agents/base.py — a shadow module never imported at runtime (package always wins); all unique content migrated into base/ Upcoming work on this branch: - Quality review pass: run quality-reviewer agent over all modified files to confirm no remaining field mismatches or import issues - software-program-manager oversight pass across all pipeline work - RoutingAgent refactor: replace hardcoded CodeAgent creation (routing/agent.py:491,553) with AgentRegistry.select_agent() + agent instantiation map for all 10 agent types - AgentOrchestrator: thin wrapper over AgentRegistry adding route(), delegate(), chain() — builds on this foundation - Capability vocabulary standardization across all 17 YAML configs - Integration tests: verify AgentRegistry loads all 17 YAML agents without error after this fix Co-Authored-By: Claude Sonnet 4.6 --- src/gaia/agents/base.py | 391 ------------------------------- src/gaia/agents/base/__init__.py | 2 + src/gaia/agents/base/context.py | 163 ++++++++++++- src/gaia/agents/registry.py | 1 + 4 files changed, 160 insertions(+), 397 deletions(-) delete mode 100644 src/gaia/agents/base.py diff --git a/src/gaia/agents/base.py b/src/gaia/agents/base.py deleted file mode 100644 index b337c4700..000000000 --- a/src/gaia/agents/base.py +++ /dev/null @@ -1,391 +0,0 @@ -""" -GAIA Base Agent -

This commit makes the engine fully functional and reproducible on any system. BUG FIXES (src/gaia/): - hooks/production/quality_hooks.py: Replace HookResult.failure_result(metadata=...) calls with direct HookResult(...) constructors — metadata= is not accepted by the class method, causing TypeError on every PHASE_EXIT hook and halting the pipeline after PLANNING on every run. - pipeline/engine.py: Wire AgentRegistry into LoopManager at initialize() time so real ConfigurableAgent instances are dispatched instead of stub results. - pipeline/engine.py: Auto-resolve agents_dir to config/agents/ via Path(__file__) so 17 YAML agent definitions are discovered without any caller configuration. - pipeline/engine.py: Phase failure now transitions to PipelineState.FAILED instead of silently reaching COMPLETED. - agents/registry.py: Add CATEGORY_ALIASES = {"quality": "review"} so pipeline template phase keys ("quality") resolve to YAML category ("review") correctly. Result: pipeline now runs end-to-end producing real artifacts and quality_score=0.9095. PACKAGING (setup.py): - Declare 8 new packages missing from setup.py: gaia.pipeline, gaia.hooks, gaia.hooks.production, gaia.metrics, gaia.quality, gaia.quality.templates_pkg, gaia.quality.validators, gaia.agents.definitions. Without this, `pip install .` (non-editable) silently omits the entire pipeline engine — critical for reproducibility on other systems. CLI (src/gaia/cli.py): - Register `gaia pipeline` subcommand as a programmatic-only stub that prints SDK usage instructions and documentation links. Prevents "invalid choice" errors when users attempt the command. DOCUMENTATION (docs/): - docs/guides/pipeline.mdx (NEW): Full user guide — quickstart, template comparison, demo acts, failure mode, AMD/NPU tuning, troubleshooting. - docs/sdk/infrastructure/pipeline.mdx (NEW): Complete SDK reference for all public classes and methods (PipelineEngine, AuditLogger, DefectRouter, etc.) - docs/spec/pipeline-engine.mdx (NEW): Architecture specification covering state machine, phase contracts, audit hash chain, concurrency model. - docs/reference/cli.mdx: Added gaia pipeline section + Pipeline card in See Also. MetricsCollector import guarded with try/except. - docs/docs.json: Registered all three new pages in correct nav groups. EXAMPLES (examples/): - pipeline_quickstart.py: Minimum viable pipeline run, standalone. - pipeline_with_registry.py: Registry inspection and agent selection by phase. - pipeline_enterprise.py: Enterprise template with artifact and chronicle analysis. - pipeline_custom_hook.py: BaseHook subclass (PhaseTimingHook) injection pattern. - pipeline_batch.py: Bounded batch execution with execute_with_backpressure(). - pipeline_custom_agent.py: Programmatic AgentDefinition registration pattern. All examples: standalone runnable, asyncio.run() wrapped, agents_dir resolved via Path(__file__), no hardcoded system paths. TESTS (tests/unit/): - test_pipeline_smoke.py (NEW): 19 smoke tests across 5 classes covering all public imports, PipelineContext construction, PipelineState enum, AuditLogger chain integrity, and the full quickstart async pattern end-to-end. Test results: 699 passed + 19 passed, 15 skipped, 0 failures.

Each +thought corresponds to one gap identified in the quality review. + +**Thought 1 — Template namespace collision (CRITICAL)** +The original plan used `"STANDARD"`, `"RAPID"`, and `"ENTERPRISE"` as template names in +`PipelineEngine` initialization snippets. These names belong to `QualityTemplate` +(`quality/templates.py`) and are only valid when calling `get_template()` from the quality +scoring subsystem. The `PipelineEngine.initialize()` method reads the template name and passes +it to `get_recursive_template()` (`pipeline/recursive_template.py`), which only recognizes +`"generic"`, `"rapid"`, and `"enterprise"` (all lowercase). Every engine code snippet in the +original plan was therefore broken at the import boundary. Correction: all engine snippets must +use `"generic"`, `"rapid"`, or `"enterprise"`. A dedicated explainer section is required. + +**Thought 2 — Async execution context missing (CRITICAL)** +All snippets containing `await` were presented as bare top-level Python, which raises a +`SyntaxError` outside of an async context. Demo attendees running these in a terminal or +plain script would see immediate failures. Correction: wrap every engine snippet in +`async def main(): ... asyncio.run(main())` and annotate Jupyter cell usage explicitly. + +**Thought 3 — AMD/hardware audience absent (HIGH)** +The original plan made no mention of how this system benefits AMD Ryzen AI NPU users. +`concurrent_loops` and `worker_pool_size` in `PipelineEngine.__init__` map directly to +bounded concurrency on NPU worker threads. Local execution means zero cloud data egress, +which is a first-order concern for enterprise AMD deployments. Correction: add a dedicated +AMD/hardware section with two talking points and at least one code reference. + +**Thought 4 — Failure/error mode not demonstrated (HIGH)** +The original plan showed only happy-path scenarios. A quality score of 0.99 is very difficult +to satisfy with minimal artifacts, guaranteeing `LOOP_BACK`. This scenario must be shown +explicitly so that audiences understand the self-correcting nature of the pipeline. Correction: +add Act 7 Scenario B with `quality_threshold=0.99` forcing the `LOOP_BACK` decision and +displaying the chronicle entry. + +**Thought 5 — Documentation file list absent (HIGH)** +The original plan referenced documentation without specifying exact file paths or `docs.json` +placement. Correction: enumerate the four required MDX files with exact paths and their +`docs.json` navigation section. + +**Thought 6 — Prerequisites section absent (MEDIUM)** +Attendees arriving at Act 1 without context could hit import errors or confusion about +`agents_dir`. Correction: add a prerequisites box before Act 1. + +**Thought 7 — Single demo ordering (MEDIUM)** +Engineering audiences want to walk through the system bottom-up. Executive/stakeholder +audiences need the "so what" first. Correction: provide two named orderings. + +**Thought 8 — Decision framework: three-audience structure** +Use a three-track audience model (Engineering, Product/Leadership, AMD/Hardware) to structure +talking points across all eight acts. Each act carries context-appropriate annotation. + +--- + +## Decision Framework: Audience-Driven Demo Strategy + +| Criterion | Engineering Track | Product/Leadership Track | AMD/Hardware Track | +|---|---|---|---| +| Primary question | "How does it work?" | "What does it deliver?" | "Why on-device?" | +| Entry point | Act 1 — Architecture | Act 7 — Live run | AMD section | +| Success metric | Code compiles, tests pass | Pipeline completes autonomously | Zero egress confirmed | +| Key risk addressed | State machine correctness | Delivery velocity | Data sovereignty | +| Recommended depth | All 8 acts, 90 min | 4 acts, 30 min | 20 min standalone | + +--- + +## Prerequisites + +Before running any code snippet in this plan, verify the following: + +**Python version:** 3.11 or higher (required for `asyncio.TaskGroup` compatibility used +internally by `LoopManager`). + +**Installation:** +```bash +cd /path/to/gaia +uv venv && uv pip install -e ".[dev]" +``` + +**`agents_dir` behavior:** When `agents_dir=None` (the default), `AgentRegistry` scans +`.claude/agents/` relative to the working directory. Pass an explicit path only if running +from outside the repository root. For the demo, `agents_dir=None` is always correct when +the shell's current directory is the repository root. + +**Lemonade server:** NOT required for pipeline orchestration demos. The `PipelineEngine` +does not call an LLM backend during these acts.

The two template systems (System A and System B) are intentionally separate. System A + lives in `gaia.quality` and is consumed by `QualityScorer`. System B lives in + `gaia.pipeline` and is consumed by `PipelineEngine`. They share vocabulary but not + objects. + +2. `PipelineContext` is a frozen dataclass. Once created, it cannot be mutated. All mutable + state lives in `PipelineSnapshot` inside the `PipelineStateMachine`. + +3. `DecisionEngine.evaluate()` applies a fixed priority order: critical defects first + (PAUSE), then quality threshold check (COMPLETE/CONTINUE), then iteration cap (FAIL), + then default (LOOP_BACK). + +4. `AuditLogger` builds a SHA-256 hash chain. Any post-hoc modification to an event's + `data` dict is detectable via `verify_integrity()`. + +5. The `PipelineEngine` does not require Lemonade server. It is an orchestration layer. + LLM calls happen inside individual agents, which are invoked by the `LoopManager`. + +6. `worker_pool_size` controls the inner semaphore that throttles `ThreadPoolExecutor` + access. `max_concurrent_loops` controls the outer semaphore. Both are set at engine + construction time and are fixed for the lifetime of the engine instance. + +### Product / Leadership Track + +1. Pipeline execution is fully autonomous. The system selects agents, evaluates quality, + and decides whether to proceed or loop back — without human intervention. + +2. Every execution produces a tamper-proof chronicle. This is the foundation for delivery + velocity metrics, quality trend analysis, and compliance reporting. + +3. The `quality_threshold` is a first-class configuration parameter, not a hardcoded + value. Product teams can raise or lower it per project without touching code. + +4. Self-correction (LOOP_BACK) is not a failure mode — it is a deliberate design. The + pipeline's job is to ensure output meets the threshold before marking completion. + +5. The three engine templates (`generic`, `rapid`, `enterprise`) represent pre-built + tradeoffs between speed and rigor. Product teams select the template; the system + handles the rest. + +### AMD / Hardware Track + +1. Zero cloud data egress. All quality evaluation, agent orchestration, and audit logging + runs in-process on the local machine. No data leaves the Ryzen AI device. + +2. `worker_pool_size` is the primary tuning knob for NPU alignment.

Overview + +The GAIA Pipeline Orchestration engine implements a **quality-gated recursive iteration** pattern. A user goal enters the system and is worked on through four ordered phases. After each full pass, a `DecisionEngine` evaluates the quality score against a configurable threshold and either approves the result or routes it back to `PLANNING` for another iteration. + +### 1.1 Design Goals + +- **Self-improving**: Quality scores drive automatic loop-back until the threshold is met or iterations are exhausted. +- **Tamper-proof**: SHA-256 hash-chained `AuditLogger` detects any post-hoc modification of the event log. +- **Bounded concurrency**: Dual `asyncio.Semaphore` prevents runaway parallelism under load. +- **Type-safe data flow**: `PhaseContract` and `PhaseContractRegistry` validate inputs and outputs at phase boundaries. +- **Local-first**: All quality scoring, audit logging, defect tracking, and metrics storage run in-process with no external I/O required. + +### 1.2 Component Map + +``` +PipelineEngine + ├── PipelineStateMachine (state transitions, chronicle) + │ └── PipelineSnapshot (mutable state view) + ├── LoopManager (concurrent loop lifecycle) + ├── DecisionEngine (pass/fail/loop-back verdict) + ├── QualityScorer (27 validators, 6 dimensions) + ├── AgentRegistry (agent discovery and selection) + ├── RoutingEngine (defect-to-agent routing) + ├── HookRegistry + HookExecutor (pre/post phase hooks) + └── RecursivePipelineTemplate (phase and agent config) +``` + +--- + +## 2. State Machine + +### 2.1 States + +| State | Description | Terminal | +|-------|-------------|:--------:| +| `INITIALIZING` | Engine is being configured | No | +| `READY` | `initialize()` completed successfully | No | +| `RUNNING` | Executing pipeline phases | No | +| `PAUSED` | Awaiting external resume signal | No | +| `COMPLETED` | All phases passed quality gate | Yes | +| `FAILED` | Unrecoverable error or iterations exhausted | Yes | +| `CANCELLED` | Cancelled by caller | Yes | + +### 2.2 Valid Transitions + +``` +INITIALIZING --> READY (initialize() succeeded) +INITIALIZING --> FAILED (initialize() error) +READY --> RUNNING (start() called) +READY --> CANCELLED (cancel() before start) +RUNNING --> PAUSED (pause() called) +RUNNING --> COMPLETED (final phase passed) +RUNNING --> FAILED (exception or iterations exhausted) +PAUSED --> RUNNING (resume() called) +PAUSED --> CANCELLED (cancel() while paused) +``` + +Terminal states have no outgoing transitions. `PipelineStateMachine.transition()` raises `InvalidStateTransition` for any attempt to leave a terminal state. + +### 2.3 Thread Safety + +`PipelineStateMachine` uses a `threading.RLock` (reentrant) for all state reads and writes. This allows the same thread to acquire the lock multiple times without deadlocking during nested calls. + +--- + +## 3. Phase Execution Model + +### 3.1 Phase Sequence + +Each call to `engine.start()` executes phases in order: + +``` +PLANNING -> DEVELOPMENT -> QUALITY -> DECISION +``` + +Each phase entry and exit fires hooks via `HookExecutor`. A hook result with `halt_pipeline=True` stops the pipeline immediately. + +### 3.2 Loop-Back Mechanism + +The `DecisionEngine` inspects the quality score after the `DECISION` phase: + +```python +if quality_score >= quality_threshold: + return DecisionType.COMPLETE +elif iteration < max_iterations: + return DecisionType.LOOP_BACK # -> back to PLANNING +else: + return DecisionType.FAIL +``` + +A `LOOP_BACK` decision does not transition to a new `PipelineState` — it resets the phase pointer and increments `iteration_count`. The `LoopManager` creates a new `LoopConfig` for each iteration. + +### 3.3 Phase Artifacts + +Each phase writes named artifacts to `PipelineSnapshot.artifacts`: + +| Phase | Artifact Key | Content | +|-------|-------------|---------| +| `PLANNING` | `planning_agent` | Selected agent ID | +| `DEVELOPMENT` | `implementation` | Implementation output | +| `QUALITY` | `quality_report` | Full `QualityReport` dict | +| `DECISION` | `decision` | `Decision.to_dict()` output | +| `DECISION` | `routing_decisions` | Defect routing results (if defects present) | + +--- + +## 4. Phase Contracts + +### 4.1 Purpose + +`PhaseContract` defines the required input and output schema for each phase. The `PhaseContractRegistry` validates actual data against contracts before phase execution begins. + +### 4.2 Structure + +```python +@dataclass +class PhaseContract: + phase_name: str + required_inputs: List[str] # Keys that must be present in input dict + required_outputs: List[str] # Keys that must be present in output dict + input_schema: Dict[str, type] # Type mapping for inputs + output_schema: Dict[str, type] # Type mapping for outputs +``` + +### 4.3 Registry + +The `PhaseContractRegistry` provides contract lookup by phase name and validates data dicts against the contract schema. Missing required keys or type mismatches raise validation errors before any phase work begins. + +--- + +## 5. Audit Logger + +### 5.1 Hash Chain Structure + +The `AuditLogger` maintains an ordered list of `AuditEvent` frozen dataclasses. Each event carries: + +- A UUID-based `event_id` +- The `current_hash`: SHA-256 of all fields including `previous_hash` +- The `previous_hash`: `current_hash` of the preceding event (or 64 zeros for the genesis) + +Any modification to an event after the fact changes its `compute_hash()` result but not its stored `current_hash`, which `verify_integrity()` detects as `HASH_MISMATCH`. Removal of an event creates a `BROKEN_CHAIN` error where the next event's `previous_hash` no longer matches the prior event's `current_hash`. + +### 5.2 Loop Isolation + +When events are logged with a `loop_id`, the logger maintains a `_loop_buckets` dict mapping each `loop_id` to its event IDs. This enables efficient retrieval of all events for a specific iteration via `get_events_by_loop()`. + +### 5.3 Concurrency + +All `AuditLogger` operations acquire a `threading.RLock`. The sequence counter (`_sequence_counter`) and hash chain (`_events`) are modified atomically within the lock. + +--- + +## 6. Defect Routing Engine + +### 6.1 RoutingRule Priority System + +`DefectRouter` holds a list of `RoutingRule` objects sorted by `priority` (ascending; lower number = higher priority). When `route_defect()` is called, rules are evaluated in priority order and the first match wins. Unmatched defects default to `"DEVELOPMENT"`. + +### 6.2 21 Defect Types + +The 21 `DefectType` values map to four default target phases: + +- **DEVELOPMENT** (14 types): `CODE_STYLE`, `CODE_COMPLEXITY`, `MISSING_DOCSTRING`, `DUPLICATE_CODE`, `MISSING_TESTS`, `INSUFFICIENT_COVERAGE`, `FLAKY_TESTS`, `SECURITY_VULNERABILITY`, `INJECTION_RISK`, `AUTHORIZATION_ISSUE`, `EDGE_CASE_NOT_HANDLED`, `PERFORMANCE_ISSUE`, `MEMORY_LEAK`, `INEFFICIENT_ALGORITHM` +- **PLANNING** (5 types): `MISSING_REQUIREMENT`, `INCORRECT_IMPLEMENTATION`, `ARCHITECTURE_VIOLATION`, `CIRCULAR_DEPENDENCY`, `TIGHT_COUPLING` +- **Default fallback**: `UNKNOWN` -> `DEVELOPMENT` + +### 6.3 RoutingEngine + +`RoutingEngine` wraps `DefectRouter` and integrates with `AgentRegistry` to resolve defect routing decisions to specific agent IDs rather than just phase names. It is invoked by `PipelineEngine._execute_decision()` when defects are present in the snapshot. + +--- + +## 7. Quality Scoring + +### 7.1 27 Validators Across 6 Dimensions + +The `QualityScorer` runs all validators asynchronously using a `ThreadPoolExecutor`. Each validator returns a `ValidationResult` with a `score` (0–100), defect list, and detail dict. + +| Dimension | IDs | Validator Count | +|-----------|-----|:--------------:| +| Code Quality | CQ-01 — CQ-06 | 6 | +| Requirements Coverage | RC-01 — RC-05 | 5 | +| Testing | TE-01 — TE-05 | 5 | +| Security | SE-01 — SE-04 | 4 | +| Performance | PE-01 — PE-04 | 4 | +| Architecture & Compliance | AC-01 — AC-03 | 3 | + +### 7.2 Score Normalization + +The `QualityReport.overall_score` is `0–100`. The pipeline engine normalizes it: `quality_score = quality_report.overall_score / 100`. This normalized value is compared against `PipelineContext.quality_threshold` (0–1). + +### 7.3 Pluggable Weight Profiles + +Dimension weights are carried by `RecursivePipelineTemplate.quality_weights`. The `QualityWeightConfigManager` provides built-in profiles and a `merge_weights` method for partial overrides. + +--- + +## 8. Concurrency Model + +### 8.1 Dual Semaphore Design + +`PipelineEngine` creates two semaphores at construction: + +```python +self._semaphore = asyncio.Semaphore(max_concurrent_loops) +self._worker_semaphore = asyncio.Semaphore(worker_pool_size) +``` + +`execute_with_backpressure` acquires both in sequence: + +```python +async with self._semaphore: # Outer cap: total concurrent pipelines + async with self._worker_semaphore: # Inner cap: parallel worker threads + result = await self.execute(workload) +``` + +This prevents both total concurrency explosion and local thread pool saturation. + +### 8.2 LoopManager + +The `LoopManager` manages the lifecycle of `LoopConfig` instances. Each phase creates a loop, which the manager tracks. The manager exposes `start_loop()`, `cancel_loop()`, and `get_all_loops()`. On `engine.cancel()`, all active loops are cancelled. + +--- + +## 9. Hook System + +### 9.1 Default Production Hooks + +Eight hooks are registered by default when `enable_hooks=True` (the default): + +| Hook Class | Event | Purpose | +|-----------|-------|---------| +| `PreActionValidationHook` | `PHASE_ENTER` | Validate inputs before phase runs | +| `PostActionValidationHook` | `PHASE_EXIT` | Validate outputs after phase completes | +| `ContextInjectionHook` | `PHASE_ENTER` | Inject additional context into snapshot | +| `OutputProcessingHook` | `PHASE_EXIT` | Post-process phase outputs | +| `QualityGateHook` | `PHASE_EXIT` | Apply quality gate rules | +| `DefectExtractionHook` | `PHASE_EXIT` | Extract defects from quality report | +| `PipelineNotificationHook` | `PHASE_EXIT` | Send notifications | +| `ChronicleHarvestHook` | `PHASE_EXIT` | Persist chronicle entries | + +### 9.2 Hook Result + +A hook returning `halt_pipeline=True` stops phase execution immediately. The engine checks this result after both `PHASE_ENTER` and `PHASE_EXIT` hook batches. + +--- + +## 10. Template System Reference + +### 10.1 RecursivePipelineTemplate Registry + +| Name | Threshold | Max Iter | Planning Agents | Quality Agents | +|------|:---------:|:--------:|-----------------|----------------| +| `generic` | 0.90 | 10 | `planning-analysis-strategist` | `quality-reviewer` | +| `rapid` | 0.75 | 5 | `planning-analysis-strategist` | `quality-reviewer` | +| `enterprise` | 0.95 | 15 | `planning-analysis-strategist`, `solutions-architect` | `quality-reviewer`, `security-auditor`, `performance-analyst` | + +### 10.2 QualityTemplate Registry (System B) + +The `gaia.quality.templates` module maintains a separate registry for `QualityTemplate` objects. These are used internally by `QualityScorer` to apply auto-pass/auto-fail bands and select agent sequences for quality evaluation. + +| Name | Threshold | Auto-Pass | Auto-Fail | +|------|:---------:|:---------:|:---------:| +| `STANDARD` | 0.90 | 0.95 | 0.85 | +| `RAPID` | 0.75 | 0.80 | 0.70 | +| `ENTERPRISE` | 0.95 | 0.98 | 0.90 | +| `DOCUMENTATION` | 0.85 | 0.90 | 0.80 | + +These names are **uppercase** and accessed via `gaia.quality.templates.get_template("STANDARD")`. They are distinct from the lowercase names used by `get_recursive_template()`. + +--- + +## 11. Error Handling and Recovery + +### 11.1 Exception Hierarchy + +All pipeline-specific exceptions inherit from a common base in `gaia.exceptions`: + +- `PipelineNotInitializedError` — operation called before `initialize()` +- `PipelineAlreadyRunningError` — duplicate `initialize()` or concurrent `start()` +- `InvalidQualityThresholdError` — threshold outside `[0, 1]` +- `InvalidStateTransition` — state machine transition violation +- `QualityScoringError` — failure in quality evaluation subsystem +- `ValidatorNotFoundError` — requested validator not in registry + +### 11.2 Phase Error Isolation + +Exceptions within a phase are caught by `PipelineEngine._execute_pipeline()`. The engine logs the exception, transitions to `PipelineState.FAILED`, sets `snapshot.error_message`, and signals the `_completion_event` before re-raising control. Callers receive the `FAILED` snapshot from `start()` rather than a bare exception. + +### 11.3 Backpressure Failures + +`execute_with_backpressure()` uses `asyncio.gather(..., return_exceptions=True)`. Any exception from a bounded execution is captured as an exception object in the results list. Callers must inspect each result and check `isinstance(result, Exception)`. + +--- + +## 12. Metrics and Observability + +### 12.1 MetricsCollector + +SQLite-backed time-series storage. Records named metrics with phase and iteration context. All data written to a local `.db` file — no network I/O. + +### 12.2 MetricsAnalyzer and BenchmarkSuite + +`MetricsAnalyzer` reads collected metrics and computes trend direction (`"improving"`, `"declining"`, `"stable"`). `BenchmarkSuite` provides repeatable performance benchmarks for pipeline throughput measurement. + +### 12.3 Chronicle + +The `PipelineStateMachine` maintains `snapshot.chronicle`: a list of dicts representing every state transition and custom event. Accessible via `engine.get_chronicle()`. Each entry contains at minimum: `event`, `timestamp`, `pipeline_id`, `phase`, and transition-specific keys. + +--- + +## Related Documents + +- [guides/pipeline](/guides/pipeline) - User guide with quickstart and AMD tuning +- [sdk/infrastructure/pipeline](/sdk/infrastructure/pipeline) - Class API reference +- [spec/orchestrator](/spec/orchestrator) - CodeAgent orchestration (separate system) +- [sdk/core/agent-system](/sdk/core/agent-system) - Base Agent class + +--- + + + +**License** + +Copyright(C) 2024-2026 Advanced Micro Devices, Inc.

Anthony Mikinka Date: Tue, 31 Mar 2026 09:36:56 -0700 Subject: [PATCH 009/107] feat(pipeline): complete metrics dashboard, template management, and comprehensive testing MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Pipeline Metrics Dashboard (Phase 1 & 2 Complete): - Backend: metrics_collector.py, metrics_hooks.py with TPS, TTFT, phase timing - Frontend: React components (MetricsDashboard, PhaseTimingChart, QualityOverTimeChart) - API: 10 metrics endpoints in pipeline_metrics.py router - Zustand store: metricsStore.ts with 5s auto-polling - Pydantic schemas: metrics.py with 16 deprecation warnings fixed Pipeline Template Management: - Service: template_service.py for YAML template CRUD operations - API: 7 template endpoints in pipeline_templates.py router - Frontend: PipelineTemplateManager, TemplateCard, TemplateEditorDialog - Zustand store: templateStore.ts for template state management - Config: generic.yaml, rapid.yaml, enterprise.yaml templates Code Quality & Fixes: - Fixed Pydantic V2 migration (Config → ConfigDict) in 16 schema classes - Fixed datetime.utcnow() → datetime.now(timezone.utc) in 18 locations - Fixed TimingHookWrapper exception handling to record failure timing - Fixed API path duplication bug in api.ts (/api/api/v1 → /api/v1) - Added js-yaml for proper YAML template parsing in editor New Frontend Dependencies: - recharts (^2.12.0) - For metrics charts (PhaseTimingChart, QualityOverTimeChart) - @monaco-editor/react (^4.6.0) - For YAML template code editor - date-fns (^3.3.1) - REMOVED (added but unused, cleaned up post-commit) - zustand (^4.5.0) - Pre-existing, used by 10 stores (follows existing pattern) Test Coverage: - Integration: test_metrics_dashboard.py (35 tests), test_template_ui.py (22 tests) - Unit: test_pipeline_metrics.py (46 tests), test_template_service.py (16 tests) - Frontend: metricsStore.test.tsx, templateStore.test.tsx, component tests - All pipeline engine tests: test_pipeline_engine.py (60 tests) Documentation: - docs/pipeline-handoff-phase1.md - Phase 1 completion report - docs/pipeline-phase1-summary.md - Comprehensive feature summary - docs/pipeline-ui-test-plan.md - UI testing strategy - docs/pipeline-validation-report.md - Validation results Files: 40 new, 71
