Callers can explicitly bound a dispatch through `max_steps`. +`PROGRESSED`, `REJECTED`, `YIELDED`, `RETRY_PENDING`, `DEFERRED`, `BLOCKED` and +`COMPLETED` describe scheduling outcomes. Unsafe input, stale state, exceeded +operational limits or changed policies raise a controlled `InvestigationError`; +duplicate concurrent dispatch raises the existing nonblocking `LockBusy`. +The server worker/scheduler remains a separate integration: no continuous daemon, +sleeping retry loop or UI is introduced. + +Input must have an accepted current-revision interpretation and hypothesis batch. +The Investigator verifies the existing budget origins and canonical case freshness; +it does not silently build missing earlier phases or reopen changed raw inputs. +Existing pending actions without a controller-owned plan/last evidence binding +are rejected explicitly. Existing initialized budgets are reused, not refilled. +When no budget config is explicitly supplied, the stored effective budget policy +is adopted automatically for subsequent accounting. An explicit changed config +still follows BudgetManager's policy-change rejection rules. + +## Deterministic cycle + +1. Select an eligible hypothesis in numeric-ID round-robin order. No selected + cause terminates the case early; alternatives remain scheduled. +2. Build a bounded context from canonical case, accepted interpretation, current + hypothesis states, questions, notes, budget policy/balances, current-revision + stored evidence and the previous result. First iteration has no prior result. +3. Persist that context and its hash before the model call. `investigation_v1` + prompt and `investigation-output-v1` schema define the model contract. +4. Execute one eligible LLM round through the existing persisted failover/retry + gateway. No global worker lock spans the external call. +5. Validate the whole reply: schema, references, confidence, question updates, + assessment binding, tool scope/arguments and projected affordability/status. +6. Persist the accepted decision as an execution plan before applying effects. +7. Settle the previous evidence's bounded semantic assessment, if present; then + reserve the next action and perform exactly one allowed query or test handoff. +8. Persist raw reply and normalized evidence, then account its deterministic + novelty through `record_evidence`. Semantic assessment occurs in a later + model iteration, not on the result's publication step. +9. Publish the updated hypothesis state and advance the round-robin cursor. + +Validation simulates settlement and reservation with the same deterministic budget +rules used by execution. A valid assessment with an invalid next action is wholly +rejected: it receives neither a refund nor partial question/confidence updates. +Local preflight reads bounded snapshots but does not dispatch query handlers or +perform external work. Runtime failures after a valid plan are recoverable from +that plan; they are distinct from technically invalid model replies. + +## Model/controller contract + +Each reply has exactly `assessment`, `update` and `next`: + +- `assessment`: null on first iteration; otherwise integer semantic score 0–100, + concrete reason and valid evidence IDs including the previous result. +- `update`: qualitative confidence (`unassessed`, `weak`, `plausible`, `supported`, + `strongly_supported`, `weakened`), known evidence IDs, existing open questions + to resolve, new nonduplicate questions and an audit note. +- `next`: one existing tool operation/arguments, an external human/automated test + descriptor, or `finish`/`reject` with a reason. + +Evidence citations must exist in the supplied current-revision context. Supported +confidence requires nonempty stored findings. Resolved questions require evidence +and cannot be unknown or already resolved. A strong-support update combined with +rejection is inconsistent and rejected. These checks establish technical grounding, +not scientific proof that the model's causal assessment is correct. + +The controller assigns action/request IDs, deadlines, checkpoint IDs, question +IDs, costs, refunds and balances. They are not model-controlled output fields. +The first loop controller works over the accepted initial hypotheses. Dynamic +`hypothesis.create`, cross-hypothesis mutation and arbitrary controller commands +are not exposed; creation limits and immutable birth records remain unchanged. +Adding replacement hypotheses requires a dedicated creation/budget/registry +contract rather than granting a model extra allocations through this schema. + +All source, database, human feedback and prior model notes are untrusted data. +Symbol occurrences and partial/empty queries retain their existing scope warnings. +No conclusions about current live server behavior are inferred from old snapshots. +The context includes current-revision evidence rather than silently dropping +history. If the configured byte bound is exceeded, dispatch rejects explicitly; +operators must align context, gateway request and artifact limits. + +## Budget and stopping + +Every investigation query/test uses a positive configured cost. Refunds remain +strictly below cost; deterministic novelty and semantic utility must both justify +them. Empty/duplicate findings earn no novelty reward, overlaps receive the +existing item-based cap, and low-information/exhausted accounts are terminal. +Model token usage and monetary metrics remain separate from investigation units. + +The new additive BudgetManager `complete` operation marks budget eligibility as +`investigation_finished`, preserves the balance and does not label a supported +hypothesis as factually rejected. Pending actions must first be assessed/closed. +The original hypothesis birth artifact is immutable; current qualitative states +live in the controller's versioned snapshots. + +Logical defaults, frozen per analysis revision: + +| Config | Default | Meaning | +| --- | --- | --- | +| `max_iterations_per_hypothesis` | 50 | Maximum research-producing model iterations; one final assessment/closure is permitted | +| `max_invalid_responses` | 3 | Consecutive rejected replies before abandoning that hypothesis's controller attempt | +| `max_questions_per_hypothesis` | 30 | Bound on accumulated question records | +| `test_deadline_seconds` | 21600 | Controller-owned external test deadline | +| `max_steps_per_dispatch` | 8 | Fair scheduler yield boundary | + +An invalid reply changes only retry/audit bookkeeping. A following prompt includes +its safe rejection code. Repeated invalid replies cause a recorded +`invalid_responses` disposition, not a factual rejection. If a previous result +cannot be assessed within that limit, it is deterministically closed with zero +reward before ending that controller attempt. Existing credit is not refilled. +The same initial hypotheses cannot be regenerated to reset their limits. + +The iteration cap prevents free model-only research loops even when credit is +large. The final extra iteration can assess a pending result but may not start +another action. Questions, earlier notes and evidence remain in immutable history. + +Once all accounts/dispositions are terminal, the case enters `BUILDING_DIAGNOSIS` +with final investigation state and deterministic `summary.md`. It does not create +a diagnosis, select a root cause or route a Coding-Agent task. The summary reports +balances, confidence, dispositions, evidence and outstanding questions. Its +countercheck marker records actions on alternatives; it is not semantic proof +that an alternative was meaningfully disproved. The later evaluator must still +consider uncertainty, evidence quality and missing counterchecks. + +## Provider failures and external tests + +Unreachable providers use existing ordered failover, configured delay and attempt +count (default 10). Pending retries return immediately with `retry_not_before`. +Exhaustion returns `BLOCKED`, preserving budgets, pending evidence and the frozen +context. Known credential, HTTP configuration, privacy/adapter and unexpected +provider failures also block the case rather than abandon its hypotheses. + +After the external problem is fixed and the due blocked case is explicitly +resumed through the lifecycle, a caller can supply a stable `retry_id` to `step` +or `run`. This opens a new transport operation for an exhausted/configuration- +failed call; it does not reset investigation iterations, credit or evidence. +It cannot override an ordinary provider backoff or reset model-invalid counters. +Saved successful execution plans are completed without another model call, even +when transport configuration changes after their publication. + +Human/automated test descriptors require explicitly configured action costs. +The controller freezes a deadline, reserves credit, stores the exact request and +delegates to `AsyncTestCoordinator`. The case returns +`BLOCKED/AWAITING_TEST_FEEDBACK` without parking a worker. No time-based charges +are applied. Authenticated, confirmed feedback resumes the same revision; the +loop imports it as evidence and later evaluates it. Web delivery/authentication, +bot steering, claims/cancellation and deadlines' notifications remain external +future adapters. See [async-tests-v1.md](async-tests-v1.md). + +## Persistence and recovery + +Context and state files are appended under `analysis/investigation/NNNN/`. +`manifest.artifacts.investigation_state` and `investigation_summary` are pointers. +Each state checkpoint has monotonically increasing sequence, parent ref and hash +binding; context hashes, identity and selected hypothesis are checked on replay. +Accepted plans are additionally bound to the original successful LLM call, +operation, saved request, prompt/schema/context and exact output document. + +Reservation, result publication, evidence accounting, assessment and final state +publication are separately idempotent. After a crash, an accepted plan resumes +those steps; existing evidence is reused, not queried again or assigned new IDs. +Repeated completion repairs/validates stored output without new provider calls. +Pointer deletion or changed policy cannot silently restart the investigation. +CaseAssembler excludes only checkpoint-declared investigation artifacts, so +expected controller work does not make the accepted case stale. + +`InvestigationLimits` are independent operational defaults: 1 MiB context, +4 MiB JSON artifact and 10,000 state checkpoints. They are adjustable safety +bounds, not permanent format limits. Compiled static schema validators are reused. +CheckpointStore caches validated generations only behind a newly computed full +archive-byte hash and unchanged limits. PackageReader additionally takes a bounded +immutable ZIP snapshot and reuses detached validation metadata for identical +snapshot hashes/limits, with a bounded entry/metadata cache. No timestamp-based +trust, extraction, skipped changed-file validation or raw archive retention in +the cache is introduced. Static bundled schema changes require process restart. + +Tests exercise round-robin investigations, real read-only queries, semantic +assessment/novelty, bounded failures, limits, reference validation, questions, +provider retries/config errors, actual local HTTP transport, portable resume, +crashes after evidence publication, external test confirmation and byte-preserving +output. The BUG-20 integration uses actual wowdiag/wowsrc data and simulated model +decisions; it tests orchestration, not real model reasoning or discovery of the +known fix. No paid/cloud model is called by these tests. diff --git a/src/viano_bug_analysis/analysis/__init__.py b/src/viano_bug_analysis/analysis/__init__.py index e15ec53..c54314f 100644 --- a/src/viano_bug_analysis/analysis/__init__.py +++ b/src/viano_bug_analysis/analysis/__init__.py @@ -8,3 +8,17 @@ from .hypothesis_summary import render_hypotheses __all__ = ["CaseInterpreter", "InterpretationResult", "InterpretationLimits", "InterpretationError", "render_interpretation", "HypothesisBuilder", "HypothesisBuildResult", "HypothesisConfig", "HypothesisError", "HypothesisLimits", "render_hypotheses"] + +__all__ += ["Investigator","InvestigationResult","InvestigationConfig","InvestigationLimits","InvestigationError"] + + +def __getattr__(name): + # Budget imports hypothesis contracts through this package.
