Architecture.md remains unchanged. + +## API and configuration + +```python +from viano_bug_analysis.analysis import HypothesisBuilder, HypothesisConfig + +policy = HypothesisConfig.load("config/analysis.local.toml") +builder = HypothesisBuilder(store, gateway, policy) +result = await builder.build(case_id, package_id) +``` + +Copy analysis.example.toml to the ignored analysis.local.toml. Defaults are +min_hypotheses=3, max_hypotheses=5 and initial_budget=100. Counts and budget must be +positive integers, and minimum cannot exceed maximum. Five is a configurable policy +default, not an immutable package-format restriction. + +The interpreter must have confirmed the current analysis revision. The builder reuses +and verifies that interpretation against its original case, raw inputs, sources, +summary and model outcome before generating anything. It does not silently start the +earlier LLM phase. Missing observations prevent unsupported hypothesis generation. +Package filenames play no functional role. + +## Prompt and source contracts + +The versioned hypotheses_v1.txt prompt is independent of model/provider. It receives +the interpretation's canonical case catalogue, the accepted interpretation statements +as I aliases with JSON pointers, the frozen generation policy and prior generations' +initial proposals. Historical proposals are labelled as untested initial proposals; +future investigation results will require their own contracts. No raw source/database +payloads are loaded into the prompt, and input text is untrusted data. + +Every candidate provides title, mechanism, rationale, distinction, case source_ids, +interpretation_ids, expected_evidence, falsifying_evidence and open_questions. All +references must exist in this exact context. The first candidate must cite human +observation/report/comment data and the first known divergence, otherwise the failure +stage, otherwise reported behavior. Alternatives may rely more on explicit technical +facts, but cannot be grounded solely in unconfirmed assumptions, external expectations +or unread implementation references. + +The controller rejects normalized duplicate titles/mechanisms, including differences +only in Unicode presentation, case, punctuation or whitespace. This cannot prove +semantic diversity or factual quality. Model adherence, plausible alternatives and +useful falsification criteria must be evaluated later with actual models and known +bugs. A nonblank distinction is not proof that mechanisms really differ. + +No IDs, priorities, statuses, confidence values, budgets, patch instructions or tool +requests are accepted from the model. Each record is controller-labelled H1, H2, ..., +positioned in returned order, status=new and confidence=unassessed. H1 is marked +tester_primary; the rest are alternatives. Percent confidence is not part of the +contract. Hypotheses are possible causes, never a confirmed root cause. + +## Budget and revision-wide cap + +Policy is saved before the first gateway request and pinned for that analysis revision. +Changing counts or initial budget during a pending/rejected attempt is rejected rather +than resetting limits. A completed generation is reused regardless of later runtime +config or attempt_id; another call cannot create a second batch or refill allocations. +New policy values take effect with a new analysis revision. + +Every accepted hypothesis receives budget_allocation.initial=initial_budget in abstract +integer investigation_units. It is independent of tokens, money, priority and model +confidence. This is an immutable creation allocation, not a live remaining balance; +budget_accounting is explicitly not_started. Future BudgetManager accounts must be +keyed by case/package identity, analysis revision and H ID and consume each allocation +once, using their persisted accounting state on resumption. + +The immutable registry records max_hypotheses, created_count, remaining_slots, next_id +and every creation's ID, origin artifact/hash/JSON pointer and allocated budget. Count +is based on creations, not active hypotheses. Rejected, abandoned or budget-exhausted +statuses cannot remove a creation or restore capacity. Only one initial batch is +published per revision; a future hypothesis.create operation must extend this durable +creation history and enforce the same saved cap. That operation is not implemented here. + +Invalid model responses are rejected atomically: no H IDs or budget allocations are +created, and no partial registry is published. Raw proposals may remain in gateway audit +artifacts, but are not accepted diagnostic hypotheses. Correcting an invalid answer uses +an explicit new attempt_id and the same frozen policy. + +New analysis revisions can allocate fresh budgets, with IDs scoped as (analysis_revision, +H ID). Old declarations, allocations and history remain unchanged in the case package. +No repeated call within the same revision can impersonate reopening or silently discard +an existing registry by removing manifest pointers. +Declared current-revision hypotheses or registries without supported creation history +are rejected rather than silently forgotten and replaced with a fresh allocation. + +BudgetManager will later enforce positive action costs, reward < cost, no reward for +duplicates, low-information termination and exhaustion. This milestone does not run any +autonomous research loop, so it does not yet debit/refund budgets or claim to enforce +investigation iteration limits. The loop must not be added before those accounting rules. + +## Durable phase and failure handling + +The normal path is three atomic generations after interpretation: + +1. Enter GENERATING_HYPOTHESES and store policy.json and context.json. +2. CaseLLMRunner records a gateway round with configured ordered failover and retries. +3. Publish hypotheses.json, registry.json and deterministic escaped hypotheses.md together, + setting manifest pointers hypotheses, hypothesis_registry and hypotheses_summary. + +hypothesis_context and hypothesis_policy also identify the saved inputs. Artifacts live +under analysis/hypotheses/NNNN/; errors/.json retains rejected attempts. +Accepted JSON, registry and summary are checked together. All original and unknown files +are preserved byte-for-byte. package_generation increases; package_id and analysis_revision +stay stable within the phase. + +The completed phase remains GENERATING_HYPOTHESES. The future investigation controller +will explicitly start INVESTIGATING_HYPOTHESES. No BudgetManager or investigation actions +are invoked here. + +Results are COMPLETED, RETRY_PENDING, DEFERRED, BLOCKED or ERROR. Unavailability uses the +existing configurable ten-round policy, persisted due times and explicit block after +exhaustion; it never sleeps inside a dispatch. Invalid answers are distinct from unreachable +infrastructure. Failures are logged with GENERATING_HYPOTHESES as the actual phase. + +Checkpoints bind policy/context/case/interpretation/model inputs and outputs by hash and +reference. Confirmed model responses survive a crash before final publication, and final +publication/index crashes replay without new hypotheses or allocations. Nonblocking +case locks prevent duplicate dispatches; generation checks reject concurrently stale +results. A remote call that never reached a durable checkpoint may repeat after cancellation +or a crash, as with the existing gateway. A successful batch cannot be regenerated by +another attempt ID, pointer deletion or terminal status markers. + +HypothesisLimits default to 1 MiB context, 32 prior generation documents and 2 MiB each +for output and summary. These are configurable operational defaults, independent of +format contracts. Underlying interpreter, gateway and ZIP limits still apply. History +is not silently truncated when a configured limit is reached. + +## Tests and remaining scope + +Offline tests cover budget equality, model-field rejection, count caps, pinned policies, +duplicate/reference rejection, registry consistency, retry/blocking, portable replay, +crash recovery, concurrent changes, reopening and preserved old allocations. A local +HTTP server tests the domain schema over the actual adapter. The optional wowdiag/wowsrc +pair regression now reaches hypothesis generation using a fixture provider and verifies +full preservation of the prior package and both original archives. + +No real model, paid endpoint or known fix is used. These tests prove contracts and package +lifecycle, not that generated candidates explain BUG-20. Investigation Tools, EvidenceStore, +budget accounting and the investigation loop are the subsequent planned milestones. diff --git a/src/viano_bug_analysis/analysis/__init__.py
