Missing earlier +phases are rejected without invoking their models. The builder replays/verifies +the diagnosis, investigation, budget, evidence and raw-input freshness before +request generation and again before publication. An inconclusive diagnosis +returns INCONCLUSIVE without calling a model or creating a coding request. + +The new `change_request_v1` prompt supplies the canonical case, accepted +interpretation, exact diagnosis, current-revision evidence, hashed local source +and database references, immutable bugfix policy and frozen retry policy. +All report, source, feedback and previous model text are untrusted data. + +The model proposes only status, problem_summary, affected_scope, required_change, +implementation_intent, implementation_guidance, constraints, preserve, +forbidden_changes, do_not_fix_by, validation_requirements, missing_information +and reason. Each affected scope entry has a source/database kind, declared safe +source_ref and evidence IDs; the findings must actually reference that local +artifact. A ready request requires scope related to stored root-cause evidence, +nonempty validation requirements and no missing information. Unknown paths, +IDs, duplicated scopes, incorrect roles and model policy/task injections are +rejected as a whole. Partial/empty results do not establish an available API. + +The controller supplies task.type=bugfix, case/package identity, a case-scoped +CR-NNNN ID, analysis revision, diagnosis pointer/hash, unchanged root cause, +unchanged observed/expected interpretation statements, prompt/context/model-call +bindings and selected project_context_refs with source hashes/sizes. +`change-request-v1` wraps the accepted model-specific fields under `request`; +controller-owned fields are top-level. The fixed policy is recreated by code, +verified on replay and explicitly has precedence over case-specific guidance: + +- Smallest practically sufficient fix; no new features or unnecessary refactoring. +- Preserve behavior outside the diagnosed defect and avoid unrelated file/row changes. +- Do not invent APIs, schemas or symbols; use only verified local context. +- Report missing implementation context instead of guessing. +- No deployment, restarts or production access. + +Prose guidance still requires semantic review; reference/schema validation cannot +prove the causal diagnosis or detect every invented identifier in natural language. +Offline tests verify orchestration and contracts, not real-model bugfix quality. + +## Waiting, rejection and review + +Each build dispatch performs at most one eligible provider round, through the +existing durable gateway/failover logic. There is no sleeping worker or new +investigation debit. Unreachable/configuration-failed providers return retry +metadata or BLOCKED and preserve budgets. After explicit lifecycle resume, a +stable retry_id may reopen an exhausted/configuration-failed transport; it cannot +bypass normal backoff or reset invalid reply counts. + +`max_invalid_responses` defaults to 3 and is frozen per analysis revision. Omitted +configuration on resume adopts the stored policy; explicit changes are rejected. +Invalid replies append audit errors and return REJECTED with no partial request. +After the limit, a deterministic review decision records validation exhaustion. +A valid insufficient_context response also creates a failure_report.json and +moves to FAILED_TO_ANALYZE/review. The confirmed diagnosis remains preserved: +a cause can be known while its verified implementation context is insufficient. +No change_request artifact is created in either review branch. + +Context, decisions and errors live under analysis/change-requests/NNNN/. +A ready request and deterministic human summary live under +handoffs/coding/CR-NNNN/change_request.json and .md. Manifest pointers are +change_request_context, change_request, change_request_summary and failure_report. +The diagnosis replay accepts only a checkpoint-declared later CR failure report; +it still verifies the original diagnosis. All review data is checked against the +frozen decision and original hypothesis/question state. + +## Final validation and local delivery + +OutputValidator.validate is read-only: absent diagnosis/CR completion checkpoints +are rejected, so it cannot initiate missing LLM phases. Package bytes and semantic +budgets stay unchanged; existing replay mechanisms may repair reconstructible +service indices/runtime metadata. It checks package integrity, +checkpoint history, raw-input freshness, current revision, evidence provenance, +exact diagnosis/request/model bindings, fixed policy, deterministic summaries, +local context hashes and manifest pointers. Review cases require FAILED_TO_ANALYZE, +review routing, a valid failure report and no coding request. + +finalize validates first, appends analysis/output/NNNN/validation.json and advances +a successful case to OUTPUT_READY/outbox. The validation report binds identity, +revision, source generation and diagnosis/request hashes. Ready cases without a +matching validation checkpoint/report are rejected. Repeated finalization validates +the same completed generation, without another model call or budget adjustment. + +publish revalidates and atomically copies the immutable ZIP snapshot into local +outbox/ or review/. Identity hashes, revision and generation form a bounded +service-owned filename; the filename remains functionally irrelevant to readers. +Copy publication flushes/fsyncs a temporary file, uses a same-directory hard link +that cannot overwrite an existing destination, and removes the temporary name. +The destination filesystem must support hard links; unsupported filesystems fail +with a controlled storage error rather than a non-atomic fallback. Existing +identical bytes are an idempotent success; differing bytes or symlinks are rejected. +A crash before export can retry the already-finalized generation. A crash after +publication reuses the identical file. Export does not increment package generation +because it copies the exact validated bytes rather than creating another package. + +Local outbox availability is not acknowledgment by a coding agent. publish does +not set HANDED_OFF, send remote messages or count a coding handoff. A future +recipient acknowledgment/worker integration owns that transition. A case already +marked HANDED_OFF is validated but not exported again. Review exports +retain their original failure checkpoint/report; successful outputs additionally +carry the final validation artifact. + +Reopened revisions preserve all old CRs/reports and reset current output pointers. +Each new revision receives its own CR ID and validation report. Unknown input files +and all immutable older artifacts remain unchanged. The CaseAssembler excludes +only checkpoint-declared generated output paths, never arbitrary unknown files. + +ChangeRequestLimits defaults to 2 MiB context and 4 MiB JSON/summary artifacts. +These are adjustable safety defaults, not permanent package-format boundaries; +align them with gateway request and package limits. Oversized input is rejected, +never silently truncated. No secrets are deliberately introduced into output. + +Tests cover confirmed and review outputs, fixed policy/provenance, full byte +preservation, budgets, malformed replies, exhaustion, provider block/resume, +crash recovery, portable replay, conflicting export files, missing validation and +reopened revisions. The real BUG-20 archive pair reaches validated local review +with simulated model replies and no seeded known solution. + +Next milestone: continuous worker/scheduler with service-wide structured logs, +metrics, heartbeat and status diagnostics. Web feedback and bot/client adapters +remain future integrations. diff --git a/src/viano_bug_analysis/analysis/__init__.py b/src/viano_bug_analysis/analysis/__init__.py index b15c700..c6c766d 100644
