Project-independent foundations for reading, validating and extending ZIP case packages. The authoritative design is docs/architecture.md. The implemented v1 contract is documented in docs/package-format-v1.md. Job state, checkpoints and inbox admission are documented in docs/lifecycle-v1.md. Generic case construction and its input contracts are documented in docs/case-builder-v1.md. Vcore imports for wowdiag/wowsrc are documented in docs/vcore-adapters-v1.md.

Requires Python 3.11 or newer.

python -m venv .venv
.\.venv\Scripts\python.exe -m pip install -e ".[test]"

The lifecycle foundation supports one-pass inbox processing, resumable package checkpoints and a deterministic generic CaseBuilder. An async LLM gateway and CaseInterpreter provide interpretation and bounded initial hypothesis generation, with durable per-hypothesis budget accounting. An LLM-driven investigation controller connects read-only queries, durable evidence and asynchronous test handoffs. Final evaluation produces traceable diagnoses or human review. Confirmed diagnoses can produce policy-bound Change Requests, with final output validation and atomic local outbox/review publication. Opt-in operational telemetry observes the existing APIs. A continuous worker remains a future milestone.

A bounded single-case command-line trial now connects import, analysis and local delivery with telemetry: first real LLM trial. Use python -m viano_bug_analysis.trial --help. Only its run command makes LLM requests; prepare and check do not contact model services.

Expected-behavior resolution and the read-only provider contract: expected-behavior-v1.md.

Configurable LLM transport, failover and durable retries: llm-gateway-v1.md, with example configuration.

The first domain LLM phase and its source-reference contracts: case-interpretation-v1.md.

Initial hypotheses, revision-wide creation limits and equal budget allocations: hypothesis-builder-v1.md, with analysis configuration.

Durable investigation budget accounting, configurable costs/rewards and stopping rules: budget-manager-v1.md, with budget configuration.

Case-local asynchronous test requests, confirmed feedback and budget-preserving event-driven resume: async-tests-v1.md. Web UI and external bot/client adapters are future integrations.

Read-only packaged source/database queries and the strict tool allowlist: investigation-tools-v1.md.

Portable evidence records, provenance, case-wide IDs and novelty-aware budget integration: evidence-store-v1.md.

Resumable, bounded LLM investigation cycles and their controller contracts: investigation-loop-v1.md, with investigation configuration.

Final hypothesis evaluation, traceable diagnoses and controlled human review: diagnosis-builder-v1.md, with diagnosis configuration.

Policy-bound coding requests and validated, resumable local output delivery: change-request-v1.md, with change request configuration.

Opt-in operational logs, safe error chains, metrics, heartbeat/progress and passive queue diagnostics: telemetry-v1.md, with telemetry configuration.
