It implements no hypotheses, root-cause +diagnosis, Investigation Tools, patches or Change Requests. Architecture.md is unchanged. + +## API and prerequisites + +```python +from viano_bug_analysis.analysis import CaseInterpreter +from viano_bug_analysis.llm import GatewayConfig, LLMGateway + +gateway = LLMGateway(GatewayConfig.load("config/llm.local.toml")) +interpreter = CaseInterpreter(store, gateway) +result = await interpreter.interpret(case_id, package_id) +``` + +CaseBuilder must already have confirmed the current analysis revision. The interpreter +verifies its checkpoint, manifest pointer, identities and current raw-input fingerprint +before preparing a request. It does not silently build an absent case. Changed raw inputs +require a new analysis revision. No identity or state is inferred from the ZIP filename. + +The API returns COMPLETED, RETRY_PENDING, DEFERRED, BLOCKED or ERROR. Storage/input problems +raise InterpretationError with a diagnostic code; concurrent dispatches raise LockBusy. +The async API supports independent cases while a provider awaits its response. It is not +a continuously running worker daemon; the caller schedules due retries. + +## Versioned prompt and bounded context + +`llm/prompts/case_interpretation_v1.txt` is independent of provider and model. The domain +PromptBuilder deterministically serializes a projection of the canonical case. The +system prompt treats reports, comments, filenames, URLs and source excerpts as untrusted +data. It forbids root-cause assertions, new causal hypotheses, implementation guidance +and tool execution. There is no tool/command execution interface in this phase. + +The context contains a reference catalogue whose entries retain their canonical JSON +pointers and original data/provenance: + +| IDs | Contents | +| --- | --- | +| O / C / T / E / F / R | Existing observations, comments, tester hypotheses, expectations, facts and reproductions | +| B | Report titles and summaries | +| S | Explicit reproduction steps | +| N | Canonical entities | +| D | Data-quality issues | +| Q0001 | Expected-behavior completeness | +| X | Metadata for unread runtime, source, database and research references | + +Aliases B/S/N/D/Q/X are scoped to this exact context and case hash. Existing record IDs +remain unchanged. Large raw payloads, original archives, arbitrary unclassified files +and source/database file contents are not loaded into the prompt. Facts represented +only by value_ref remain unread references. Inline facts and explicit expectations +retain their source authors/timestamps and any original-data or external-source provenance. + +InterpretationLimits defaults are 8 MiB for the canonical case, 512 KiB context, 2048 +catalogue entries, and 2 MiB each for accepted output and Markdown. They are configurable +operational safeguards, not permanent format bounds. Gateway/package limits also apply. +For cases built with custom CaseBuilderLimits, pass those as case_limits to CaseInterpreter. + +## Output contract and validation + +`case-interpretation-output-v1.schema.json` contains precisely these required sections: +observed_behavior, expected_behavior, tester_assumptions, confirmed_technical_facts, +behavior_gap, first_known_divergence, failure_stage, contradictions, unknowns, +relevant_entities, investigation_direction and interpretation_summary. + +Statements contain text and source_ids. Gaps, divergence and failure stage may be null; +collections may be empty. Extra keys—including identities, root_cause, hypotheses, patch +or tool requests—are rejected. The controller supplies identities, analysis revision, +case/context hashes, actual LLM outcome reference and metadata in the persisted wrapper. +The model cannot overwrite those authoritative fields. + +After gateway schema validation, the interpreter validates the whole response against +the actual reference catalogue: + +- Every cited source exists, and every relevant entity is a real unique N alias. +- Intended behavior cites E records only; tester assumptions cite T/C records. +- Confirmed technical facts cite only inline F facts. Tester assumptions and external + expectations cannot become local technical proof. +- A gap/divergence cites both intended behavior and an observation/report/comment; + a reproduction step alone does not establish a divergence. +- Contradictions need at least two distinct supplied sources and cannot use unread payloads. +- Incomplete/missing/conflicting intended behavior remains an unknown citing Q0001. + With no E records, an invented expectation or justified gap cannot pass validation. + +Completeness and tester/external_research/combined provenance are copied from the case, +not decided by the model. External intended behavior remains distinct from local +implementation evidence. An invalid response is rejected atomically: no interpretation +pointer or summary is published. Its raw gateway outcome and a separate rejection report +remain available for audit. The phase stays INTERPRETING_CASE; invalid output is not +misclassified as unreachable infrastructure or exhausted diagnostic investigation. + +Schema/reference validation cannot prove that free-text paraphrases are true, detect +every hidden causal assertion, or prevent all semantic prompt injection. The prompt and +typed source constraints bound the task; actual model adherence must be evaluated with +real providers and known cases. No heuristic word blacklist pretends to provide that proof. + +## Durable lifecycle and package preservation + +Normal progression is three atomic package generations after a built case: + +1. Enter INTERPRETING_CASE and preserve context.json with a case-interpreting checkpoint. +2. CaseLLMRunner records a gateway round using the existing failover/retry policy. +3. Publish accepted case_interpretation.json and case_interpretation.md together with a + case-interpreted completion checkpoint and manifest pointers. + +The completed phase stays INTERPRETING_CASE. The future Hypothesis Builder will explicitly +start GENERATING_HYPOTHESES. No later phase is executed in this milestone. + +Phase artifacts live under `analysis/interpretations/NNNN/`: context.json, accepted JSON, +deterministic Markdown and immutable errors/.json reports. This phase-specific +layout allows later phases to append their artifacts without changing PackageWriter's +existing rule that analysis/revisions/NNNN namespaces are frozen once present. All artifact +files remain immutable and carry their analysis revision. Existing original/ data, old +analysis and unknown files remain byte-identical. package_id stays stable; only package_generation +advances within a revision. + +Manifest pointers are interpretation_context, case_interpretation and +case_interpretation_summary. The JSON result is authoritative; the Markdown is a pure +escaped rendering with no additional interpretation. Both case and context SHA-256 +bindings identify the exact canonical JSON serialization produced by CaseBuilder. + +The default stable operation uses attempt_id="default". Retries share that ID, request +and configuration fingerprints. A completed phase is validated and reused independently +of a later provider/config change. A confirmed gateway result is also reused if a crash +occurred before phase publication; publication/index crashes are recovered through +checkpoint replay. Only an unconfirmed remote call may need repeating. Cancellation +releases operation locks and keeps confirmed preparation for resumption. + +A deliberately changed provider configuration or a corrected response after rejection +can use a new attempt_id. Rejections stay in the same analysis revision without replacing +old records. An exhausted BLOCKED operation needs explicit lifecycle resumption and a +new attempt_id, as described in llm-gateway-v1.md. Underlying case changes still require +a new analysis revision rather than another attempt against a stale canonical case. + +## Verification scope + +Tests cover structured/reference rejection, missing expectations, provenance separation, +bounded context, immutable output, escaped summaries, retry/defer/block behavior, +portable replay, cancellation, concurrency and crash recovery. A real local HTTP server +exercises the bundled adapter with the domain schema and prompt. The optional BUG-20 +regression now includes interpretation publication and byte-for-byte preservation of +the supplied packages using a fixture provider. + +These are offline integration checks, not proof that a model can explain or solve BUG-20. +No real LLM endpoint, cloud credentials, live research or known fix is supplied in these +tests.
