The JSON-schema artifact validator enforced `required` keys but not array
contents, so a model could emit `"requirements": []` (or `"steps": []`,
`"components": []`) and pass — a misread brief sailing through as a valid
artifact. That empty-list gap is the hole under role-reliability §3's
keystone ("force the analyst to define done; verifiability propagates
downstream").
- JsonSchemaProperty gains `minItems` and `items` (recursive), letting a
schema declare a required-non-empty / element-typed array.
- JsonSchemaValidator checks array length >= minItems and each element's
declared item type (with index in the message). Pure + deterministic;
single-return to stay within the detekt ReturnCount budget.
- Role-pipeline schemas tightened: analysis.requirements, design.components,
impl_plan.steps → minItems 1 + items string. Prompt-free — these arrays
were already `required`; this only forbids them being empty.
§4 (force a non-empty `alternativesConsidered` on the architect) is
deliberately NOT taken: it contradicts the standing "don't raise
alternatives unnecessarily" preference the architect prompt already encodes.
Live QA audit of role_pipeline against a sample repo surfaced and fixed a
chain of defects that prevented any tool+artifact workflow from running
end-to-end. The pipeline now completes cleanly with a real, validated,
reviewed file change.
- F-008 workflow: propagate stage token_budget -> generationConfig.maxTokens
(TomlWorkflowLoader) so large stages stop truncating at the 2048 default.
- F-009 tools/kernel: file_read missing-file is recoverable; recoverable tool
errors feed back into the loop instead of aborting the stage.
- F-010/F-018 kernel: reject premature stage_complete and nudge the model to
emit the owed artifact / invoke a write tool (bounded by MAX_TOOL_ROUNDS).
- F-011 schemas: list-typed artifact fields string -> array (analysis/design/
impl_plan) to match model output.
- F-012 kernel: strip an outer markdown code fence from LLM artifacts.
- F-013 validation: payload-validation failures are retryable; structural
failures stay terminal (wires the invariant-#7 reject+retry contract).
- F-014 tools: file_edit schema matches its real params; edits emit a diff.
- F-015 kernel: record tool-execution events + materialise a real file_written
artifact from the on-disk write; gate validation so a no-write stage cannot
be rubber-stamped (no more false-success runs).
- F-016 server: raise stageTimeoutMs 60s -> 180s for slow local models.
- F-019 artifacts/kernel: file_written artifact carries the unified diff so the
reviewer can verify the change (shared DiffUtil; file_write emits a diff too).
- F-020 tools: model-correctable file_edit failures are recoverable + steer
toward replace/file_write over the fragile patch op.
