## Description
|
|
|
|
Review 002's deployment-knob coverage gaps — production code paths
|
|
dark in **all** binaries:
|
|
|
|
- **`with_ws_idle_timeout`** (`server/adapter.rs:228-242`): the WS-13
|
|
server-side knob is called by no test — a regression silently
|
|
disables the idle timer on the default surface while tungstenite
|
|
unit tests stay green. Add: integration test building via
|
|
`HttpAdapter::new(...).with_ws_idle_timeout(Some(small))` → connect
|
|
a WS client → assert server closes with 1001 ≈ at the knob; plus a
|
|
`None` variant (session survives a long silence). NOTE: the
|
|
progress-semantics change from review-002-ws13-idle-progress lands
|
|
first — the 1001 assert must reflect final semantics (progress-based).
|
|
- **`call_tool` production dispatch** (`to_mcp.rs:459-468`): all four
|
|
tools + unknown-name are tested via `invoke_tool`, which **bypasses**
|
|
`call_tool` — the rmcp-entered routing shell (what production runs)
|
|
has never executed. Test: in `from_mcp_integration.rs`'s live-server
|
|
harness, one client-side `peer.call_tool("search"|"batch"|"schema"|
|
|
"call"|unknown)` round-trip through the real rmcp protocol.
|
|
- **Small dark arms (COV-12)**, one test each: `to_mcp`
|
|
missing-argument validation for `schema` (None args) and `batch`
|
|
(empty/no calls) tools (:175, :221); `from_mcp` non-object tool
|
|
arguments wrapped as `{"value": …}` (:405-408); `routes.rs` first-
|
|
line-invalid-JSON `/publish` 400 (:263-266); `decoy.rs`
|
|
directory→index.html resolution (:133-138);
|
|
`openapi_spec.rs` array-of-`$ref` resolution (:428-433 — the arm the
|
|
coverage pass initially mis-flagged; the *code is correct*, add the
|
|
test) and `style: simple` + `explode: true` rejection (:561-566).
|
|
|
|
## Acceptance Criteria
|
|
|
|
- [ ] Idle-knob integration test (Some(small) → 1001 per final
|
|
semantics; None → survives) in ws_upgrade_session.rs
|
|
- [ ] One rmcp-protocol `call_tool` round-trip test per tool + unknown
|
|
(feature `mcp`)
|
|
- [ ] Each small arm test lands (list above; skip any proven
|
|
unreachable during implementation — document which and why)
|
|
- [ ] `cargo llvm-cov --all-features` re-run: http_client.rs function
|
|
%, adapter.rs 228-242, to_mcp.rs call_tool no longer dark
|
|
- [ ] `cargo test --all-features`, `cargo clippy --all-features
|
|
--all-targets -- -D warnings`, `cargo fmt --check` pass
|
|

- src/server/adapter.rs:228-242, src/adapters/to_mcp.rs:459-468, tests/ws_upgrade_session.rs, tests/from_mcp_integration.rs
|
|
- tasks/websocket/review-002-ws13-idle-progress.md (lands the semantics this asserts)
|
|
- tasks/adapters/review-002-oai11-ref-memoization.md (owns the array-$ref behavior; this adds only its test if not already added there)
|
|
|
|
## Notes
|
|
|
|
Sequence after ws13 (the idle-knob assert must match final semantics).
|
|
The array-`$ref` test is coverage-only insurance — if
|
|
review-002-oai11-ref-memoization already added it, check the box and
|
|
skip. The from_mcp/`{"value": …}` wrap test goes in
|
|
from_mcp_integration.rs (real wire behavior).
|
|
|
|
## Summary
|
|
|
|
COV-11b/12 closed: rmcp production call_tool round-trip for all 4 gateway tools, mcp schema/batch dark arms, /publish first-line JSON arm (updated to 422), decoy index.html, array-$ref + style:simple-import-arm pins. COV-11b idle-knob already covered by ws13's tests. Test-only.
