+# Enforce resolved tool argument constraints before every dispatch
+
+- **Status**: Todo
+- **Kind**: Bug
+- **Authors**: jp
+- **Date**: 2026-08-21
+
+Tool-call validation checks missing and unknown names, but does not enforce
+parameter types, enums, array item schemas, or nested value constraints.
+It runs only for local tools; MCP and built-in tools bypass it.
+
+The recorded provider fixtures already contain invalid calls that pass through
+the test harness, including Cerebras arrays with numeric items, Google values
+outside the declared enum, and llama.cpp JSON-looking strings where an array was
+intended.
+
+`conversation.tools.<name>.parameters` documents enums as allowed-value
+constraints and supports forcing a value.
+Those constraints must be enforced by JP rather than treated only as model
+guidance.
+
+Open PR \#998 validates resolved schema definitions but does not validate
+argument instances at dispatch time.
+
+Acceptance criteria:
+
+- Validate required fields, unknown fields, JSON types, complete-value enums,
+  `items`, and nested `properties` against the resolved tool schema.
+- Apply the same validation before local, MCP, and built-in dispatch.
+- Normalize strict-provider `null` placeholders back to omission or the
+  configured default before validation.
+  Optional nullable values must not leak into a tool whose source schema does
+  not accept `null`.
+- Return the existing invalid-arguments tool response without invoking the
+  target.
+- Add tests using invalid calls taken from the Cerebras, Google, and llama.cpp
+  fixtures.
+- Add tests proving MCP and built-in parameter overrides are enforced.

+# Exercise recorded provider tool rounds through a production-shaped loop
+
+- **Status**: Todo
+- **Kind**: Chore
+- **Authors**: jp
+- **Date**: 2026-08-21
+
+`TestRequest::tool_call_response` creates a fresh `ChatQuery` with no tools.
+Production keeps the full tool list on every streaming cycle and resets a forced
+choice to `Auto` after execution.
+
+The mismatch is visible in the fixtures: Ollama says no tool is defined after JP
+sends a result, and some Google forced-tool follow-ups contain no assistant
+message.
+These tests do not cover repeated tool calls or continued tool availability.
+
+Acceptance criteria:
+
+- Add a recorded-provider test path that retains tool definitions across the
+  post-result request, matching `run_turn_loop`.
+- Use a fake executor so the recorded response is produced by the same request,
+  execute, append-result, request cycle used in production.
+- Cover a second tool call after the first result.
+- Cover parallel calls where the provider supports them.
+- Assert that forced choice becomes `Auto` while tools remain declared.
+- Keep lower-level provider serialization tests where useful, but name them as
+  such.

+# Make provider cassette tests assert semantic outcomes and consumed interactions
+
+- **Status**: Todo
+- **Kind**: Chore
+- **Authors**: jp
+- **Date**: 2026-08-21
+
+The provider VCR tests snapshot whatever happened but usually have no semantic
+assertion.
+`Vcr::cassette` also discards the `MockSet` returned by `playback_async`, so
+recorded interactions are not checked for exactly one use.
+Optional tool follow-ups can be silently skipped and leave stale cassette
+entries without failing.
+
+Current green examples include empty llama.cpp model details, malformed Ollama
+structured output, invalid tool arguments, and empty Google post-tool responses.
+
+Acceptance criteria:
+
+- Assert every cassette interaction is consumed exactly once during playback.
+- Fail on unexpected requests and unused recorded responses.
+- Require request-kind invariants: forced tool name, tool argument conformance,
+  structured schema conformance, nonempty or explicitly empty post-tool outcome,
+  requested model ID, and nonempty model lists.
+- Remove no-op assertion defaults where the request kind has a meaningful
+  contract.
+- Make skipped `ToolCallResponse` requests explicit in the test declaration
+  rather than controlled by a boolean that silently returns `None`.
+- Add a harness regression test with an intentionally unused second cassette
+  interaction.

+# Make provider fixtures deterministic and sanitize recorded machine data

+- **Status**: Todo

+- **Authors**: jp
+- **Date**: 2026-08-21
+
+Several fixtures contain avoidable nondeterminism or local machine data:

+- The common tool prompt asks the model to provide arbitrary arguments.
+- `banana.jpg` depicts an apple and the test uses a substring assertion.

+  turns in one cassette on the same identity.
+- Extend fixture post-processing to normalize user paths, host names, device
+  UUIDs, process IDs, and timestamps when those values are not under test.
+- Add a fixture lint test that rejects common absolute home-directory patterns
+  and known secret header/query fields.

+
+The llama.cpp fixture requests `llamacpp/qwen3.5:9b`, while `/v1/models` reports
+`unsloth/Qwen3.5-9B-GGUF`.
+`map_model` strips the vendor prefix to `Qwen3.5-9B-GGUF`, so

+- **Status**: Todo
+- **Kind**: Bug
+- **Authors**: jp
+- **Date**: 2026-08-21
+
+The Ollama structured-output cassette returns plain text despite receiving the
+title JSON schema.
+`EventBuilder` wraps the parse failure in `Value::String` and emits
+`ChatResponse::Structured`, so the background title task treats it as structured
+data, extracts no title, and returns success without updating the title.
+
+Evidence:
+
+- `crates/jp_llm/tests/fixtures/ollama/test_structured_output.yml`
+- `crates/jp_llm/tests/fixtures/ollama/test_structured_output.snap`
+- `crates/jp_llm/src/event_builder.rs`
+- `crates/jp_task/src/task/title_generator.rs`
+
+Acceptance criteria:
+
+- Malformed JSON cannot be represented as a successful
+  `ChatResponse::Structured`.
+- Parsed JSON is checked against the schema attached to the request.
+- A malformed or nonconforming response produces a typed failure that the retry
+  layer or caller can handle.
+- Background title generation reports the failure rather than silently
+  succeeding without a title.
+- Provider fixture tests assert schema conformance, including the existing
+  Ollama cassette.
+- Cover valid JSON with the wrong shape, wrong field types, and wrong array
+  cardinality.

+- **Authors**: jp
+- **Date**: 2026-08-21
+
+Provider model-list fixtures are too large to review and several model-details
+cassettes duplicate the full catalog byte for byte.
+OpenRouter has two identical 29,699-line cassettes plus a 10,111-line model

+  coverage is useful.
+- Test model mapping, sorting, deduplication, deprecation, capability inference,
+  and lookup with small curated static responses.
+- Reuse one cassette response for `models` and `model_details` when both
+  production methods call the same endpoint.
+- Replace full-catalog snapshots with exact assertions over selected
+  representative records and list invariants.
+- Keep a test proving an unknown requested model returns the intended fallback.
