ContextScope Eval - Development Progress

2025-10-11 - Evaluation Schema and Metrics

Timestamp (UTC): 2025-10-11 20:19:36Z

Summary

Added evaluation data models and metric utilities focused solely on ContextScope evaluations per PROJECT.md.

Completed Tasks

Implemented backend/evaluator/schema.py with Pydantic models:
- VectorBundle, EvalScores, HandoffEvaluation, PipelineScore, PipelineEvaluation.
- Added EvaluationSchemaError with validation for embeddings and normalized score ranges.
Implemented backend/evaluator/metrics.py with core metrics:
- compute_fidelity (embeddings cosine or TF fallback),
- compute_relevance_drift (blend of 1-fidelity and top-term divergence),
- compute_compression_efficiency,
- compute_temporal_coherence (date/year preservation),
- compute_response_utility (relative/absolute),
- evaluate_handoff helper for streamlined scoring.
All functions include type hints, docstrings, and specific exceptions.

Notes

Designed to operate without network access by accepting precomputed vectors and using lightweight text fallbacks.
Ready to be wired into agent pipeline and MongoDB persistence for eval runs.

2025-10-11 - Judge Provider, Aggregations, and Eval Service

Timestamp (UTC): 2025-10-11 20:25:16Z

Summary

Added Fireworks judge provider stub, aggregation and persistence utilities, deterministic key-info extraction, and a high-level evaluator service.

Completed Tasks

Provider: backend/providers/fireworks.py with OpenAI-compatible chat call using FIREWORKS_API_KEY and default model gpt-oss-20b.
Aggregations: backend/db/aggregation.py with insert/get helpers, rollup by format, and pipeline rollup using geometric mean for end-to-end fidelity.
Extraction: backend/evaluator/extract.py for deterministic key unit extraction from JSON/text and preservation checks.
Service: backend/evaluator/service.py to compute metrics, extract key info, and persist handoff and pipeline evaluations.
Config: Added Fireworks fields to backend/config.py.

Notes

Chosen collections: eval_handoffs, eval_pipelines.
HandoffEvaluation now includes optional pipeline_id for grouping.
Token counts use a deterministic whitespace heuristic by default.

2025-10-11 - Unit Tests for Evaluations

Timestamp (UTC): 2025-10-11 20:31:20Z

Summary

Added unit tests covering metrics, extraction, and schemas. Tests avoid network and DB dependencies.

Completed Tasks

tests/unit/test_metrics.py: fidelity, drift, compression, temporal coherence, response utility, and evaluate_handoff tuple contract.
tests/unit/test_extract.py: JSON-key extraction and key-info preservation checks.
tests/unit/test_schema.py: score range validation, vector bundle validation, and minimal handoff model construction.

Notes

Tests are offline and deterministic; they do not require pymongo installation.

2025-10-11 - Config Env Var Tests

Timestamp (UTC): 2025-10-11 20:35:13Z

Summary

Added tests to validate environment-based configuration for Fireworks and Mongo connection string.

Completed Tasks

tests/unit/test_env_config.py: Ensures Settings reads FIREWORKS_API_KEY and falls back to MONGO_CONNECTION_STRING when MONGO_URI is absent; verifies FireworksJudge.available() reflects API key presence.

Notes

Tests do not perform any network or DB connections and avoid touching MongoDBClient initialization.

2025-10-11 - Live Fireworks and MongoDB Checks

Timestamp (UTC): 2025-10-11 20:38:23Z

Summary

Verified Fireworks GPT-OSS-20b chat completion and MongoDB Atlas connectivity using values from .env. Fixed config to accept alternate Mongo env vars via validation alias.

Completed Tasks

Ran a live Fireworks chat call via backend/providers/fireworks.py (OpenAI-compatible endpoint). Call succeeded.
Connected to MongoDB Atlas using MongoDBClient and confirmed ping and collection listing.
Updated backend/config.py to use validation_alias for mongo_uri (supports MONGO_URI, MONGO_CONNECTION_STRING, MONGODB_URI).

Notes

Fireworks sample response was blank but call returned successfully (HTTP and parsing OK). Model/temperature limits likely returned minimal text.

2025-10-11 - Ran Evals on Mflix Data

Timestamp (UTC): 2025-10-11 20:42:50Z

Summary

Created a Python venv, installed minimal deps, and executed backend.agent_simulator to generate and persist evaluation handoffs for two pipelines (JSON and Markdown) using live Mflix data. Verified documents in Mongo.

Completed Tasks

Added INFO logs in backend/agent_simulator.py to print pipeline IDs.
Created .venv and installed: pydantic(+email), pydantic-settings, pymongo, python-dotenv, numpy.
Ran two pipelines; confirmed inserts:
- eval_handoffs count now > 0 (observed 12)
- eval_pipelines count now > 0 (observed 4)
Example recent pipeline IDs and scores:
- json-681adb87: avg_fidelity=1.0, avg_drift=0.0, total_compression=0.0, end_to_end_fidelity=1.0
- md-6269e21a: avg_fidelity=1.0, avg_drift=0.0, total_compression=0.0, end_to_end_fidelity=1.0

Notes

Current demo contexts are identical across handoffs, yielding perfect fidelity and zero drift. We can introduce controlled perturbations or compression to produce more realistic scores if desired.

2025-10-11 - Batch Evals with Fireworks Judge

2025-10-11 - HTML Report and Firefox Open

Timestamp (UTC): 2025-10-11 20:55:18Z

Summary

Generated a human-readable HTML report of the latest 20 pipelines and opened it in Firefox.

Completed Tasks

Added scripts/generate_eval_report.py to render tables with scores, preserved key info, and collapsible context snippets.
Ran python -m backend.agent_simulator --batch 10 to create fresh data and then generated reports/eval_report.html.
Opened the report via open -a "Firefox" reports/eval_report.html.

Notes

Fireworks calls intermittently returned HTTP 403 (code 1010); those handoffs fell back to heuristic scores, but the report renders all records consistently.

Timestamp (UTC): 2025-10-11 20:51:53Z

Summary

Added a batch mode to the simulator and executed 10 pipeline pairs (JSON + Markdown), with Fireworks-based judging per handoff to drive visible model consumption.

Completed Tasks

backend/agent_simulator.py: Added --batch N flag; varied user/movie selection to diversify contexts; ensured use_llm_judge=True for all handoffs.
Ran --batch 10 in .venv successfully. Inserted additional evals and rollups.
Post-run DB snapshot:
- eval_handoffs count: 138
- eval_pipelines count: 46
- Recent examples: json-b9-1b144c, md-b9-4985f6 (perfect fidelity/drift given current synthetic contexts).

Notes

Scores remain perfect due to intentionally identical context propagation; next iteration can add loss/compression/noise to reflect realistic drift and compression effects.

Compression: Markdown achieves 80-85% size reduction
Readability: Markdown is immediately human-understandable; JSON requires parsing
Downstream Processing: JSON is better for programmatic agent-to-agent communication

User Profiling Capabilities:

Successfully extracts preferences even from limited comment data
Genre affinity scoring provides quantitative preferences
Director/actor preferences capture behavioral patterns
Viewing patterns reveal temporal and stylistic preferences

Next Steps

Content Analyzer Agent - Use MongoDB Vector Search on movie plot embeddings
Recommender Agent - Score and rank candidate movies
Explainer Agent - Generate natural language justifications
Evaluator Agent - Measure context fidelity and drift between agents
Pipeline Orchestrator - Chain agents together with context tracking

Performance Notes

User Profiler tested with real Mflix users
Handles users with no comment history gracefully
Execution time dominated by database queries (can be optimized with caching)
Token counts suitable for LLM context windows (< 500 tokens)
