PR-7 (v0.18 dogfood probe-first) 머지 후 PR-5 의 test `ask_tool_routes_multi_hop_true_to_decompose_first` 가 stale empty-KB contract 로 deterministic fail. test-only fix — production code 0 touch.
- `minimal_config`: `score_gate = 0.0` (probe 의 second gate `top_score < score_gate` 우회, test config isolation).
- fixture `workspace_root/note.md`: "This note is about a compound containing X and Y in detail." — build_match_string 의 token_and branch (FTS5 implicit-AND) 가 `compound` + `about` + `and` 셋 다 매칭 필요. empirical SQLite REPL (V007 trigram DDL) 로 1 hit 확정.
- 기존 assertion 보존, single-pass branch 도 query "anything" 으로 fixture 미매칭 → NoChunks refusal 유지.
- 신규 `_multi_hop_short_circuits_when_probe_empty` test (REQUIRED — round-1 critic HIGH + verifier 격상): probe-empty short-circuit 의 MCP-layer wire shape pin (kebab-rag::multi_hop_empty_probe_pool_refuses_before_any_llm_call 은 RAG-layer 만 pin, MCP-layer 안전망 부재).
- module doc 갱신: 두 test 가 각각 pin 하는 contract enumerate. inline 주석 (line 94-101) 도 새 contract 정합.
- HOTFIXES.md 신규 dated entry \`## 2026-05-26 — HOTFIX #15 ...\` (date-top convention).
검증: cargo test --workspace -j 1 — 회귀 0 (known flaky 1 → 0). cargo clippy --workspace --all-targets -j 1 -- -D warnings clean.

7 new optional inputs on SearchInput: tags, lang, path_glob,
trust_min, media, ingested_after, doc_id. Validation surfaces as
error.v1 code = invalid_input via StructuredError. Dispatch builds
SearchFilters from the inputs and forwards through the existing
search_with_opts_with_config facade.
Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>
Mirrors CLI surface: same input shape, same fetch_result.v1
output. invalid_input error for missing kind-specific fields.
Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>
SearchInput gains max_tokens / snippet_chars / cursor (all optional).
Output wrapped in search_response.v1 to match CLI; existing
tools_call_search test updated to read v["hits"] instead of the bare
array.

- kebab-app: add #[doc(hidden)] to ingest_stdin_with_config (CLAUDE.md
convention — all *_with_config functions should have this attribute;
fb-31's first impl missed it on the second facade fn).
- SKILL.md: "Since v0.4.0" → "Since v0.3.1" (MCP shipped in fb-30
release v0.3.1; the wrong version claim was introduced in fb-30 doc
sync and carried forward into fb-31).
- tools_call_ingest_file: add idempotency test (second call with same
content → unchanged=1, new=0). Spec called for two tests; first impl
shipped only the happy path.
Version bump 0.3.1 → 0.3.2 deferred to separate `chore/bump-v0.3.2` PR
mirroring fb-27 + fb-30 precedent (commits 73f5d73 / 5495d96).

5th + 6th MCP tools — first mutation surface (fb-30 v1 was read-only).
Both wrap the new kebab-app facade fns + use spawn_blocking via the
existing spawn_tool helper. tools/list now returns 6 tools.

Final review fixes:
- docs/ARCHITECTURE.md: add kebab-mcp to UI subgraph + directory tree
(CLAUDE.md "add new crate" rule required this; missed in Task 12 doc sync).
- state.rs: replace forward-reference Task 10 comment with current-state
doc (config_path now wired by Task 10 commit 4a30959).
- tools_call_schema.rs: assert capabilities.mcp_server == true (already
pinned in schema_report + cli_schema, this closes the gap in mcp's own
test).
Version bump 0.3.0 → 0.4.0 deferred to separate `chore/bump-v0.4.0` PR
mirroring fb-27 precedent (commit 73f5d73 / PR #105).

Approach: extracted `pub fn build_tools_vec() -> Vec<Tool>` from the
inline `list_tools` trait impl body — `RequestContext<RoleServer>` is
non-constructible from outside rmcp (Peer::new is pub(crate)), so a
direct trait-method call was not viable without an in-memory transport
rmcp 1.6 does not expose. The helper is the single source of truth;
`list_tools` now delegates to it.
Three test cases in tests/tools_list.rs:
- 4 tools present with correct names
- search inputSchema has "required": ["query"]
- schema/doctor tools accept empty input (type=object, no required)

Adds integration test schema_tool_emits_error_v1_when_db_missing that
verifies NotIndexed errors are emitted as error.v1 JSON with isError=true.
Also fixes ErrorV1 struct to include required schema_version field per
error.v1 wire contract (docs/wire-schema/v1/error.schema.json).

Two issues from Task 7 review:
1. CRITICAL — call_tool "ask" arm called blocking ask handle from async
context. OllamaLanguageModel::new builds reqwest::blocking::Client
which creates+drops a tokio runtime → panic inside async. Fix:
tokio::task::spawn_blocking wrap. Also applied preemptively to
"search" arm (SqliteStore + Lance open are blocking IO too).
2. IMPORTANT — ask tool's retrieval mode hardcoded to Lexical (test
workaround for provider="none"); CLI default is Hybrid. Fix: add
`mode: Option<String>` field to AskInput, default Hybrid in handle,
test passes mode=Some("lexical") explicitly to keep test functional
on provider="none".

Fourth (and final v1) tool — `ask` (input: query / optional session_id).
Multi-turn via optional session_id (kebab_app::ask_with_session_with_config),
single-shot via ask_with_config when None. Refusal (grounded:false) NOT
mapped to isError — agent branches on the wire payload's grounded flag.
AskOpts has no Default impl (must construct manually). Answer carries no
schema_version field (tagged inline via entry().or_insert_with, idempotent).
Mode defaulted to Lexical: reqwest::blocking::Client::build creates and
drops a tokio runtime, panicking inside async context — the empty-corpus
refusal test avoids this via spawn_blocking; the tool itself uses Lexical
as the default mode since MCP callers typically run without an embedding
provider configured.

Third tool — `search` (input: query / mode / k). First tool with
non-empty input — establishes the pattern: SearchInput struct with
JsonSchema derive + Tool::new uses
rmcp::handler::server::common::schema_for_type::<SearchInput>() for
inputSchema + call_tool match arm parses request.arguments via
serde_json::from_value.
search_with_config takes owned Config, so state.config (Arc<Config>)
is cloned via (*state.config).clone(). Output: search_hit.v1 array —
SearchHit (kebab-core) does not carry schema_version field, so each
element is tagged inline before serialising.

Second tool — `doctor` (no input args, returns doctor.v1 JSON via
kebab_app::doctor_with_config_path). Mirrors schema tool's manual-dispatch
pattern: Tool::new entry in list_tools, match arm in call_tool, per-tool
module in tools/doctor.rs.
doctor_with_config_path takes Option<&Path> (not &Config), so KebabAppState
is extended with config_path: Option<PathBuf>. All existing callers
(initialize.rs, tools_call_schema.rs, serve_stdio_async) pass None for now;
Plan Task 10 (Cmd::Mcp wiring) will thread the actual --config path through.
doctor_with_config falls back to XDG default when config_path is None —
same behavior as bare `kebab doctor`.

First tool wired — `schema` (no input args, returns schema.v1 JSON
mirroring `kebab schema --json`). Establishes the per-tool module
pattern (crates/kebab-mcp/src/tools/<name>.rs) + error helper that maps
anyhow::Error to MCP CallToolResult.error with error.v1 content.
Dispatch pattern: manual dispatch — explicit `list_tools` + `call_tool`
overrides on `impl ServerHandler for KebabHandler` with a
`match request.name.as_ref()` arm per tool. No proc-macro magic.
Tasks 5-7 should add a new arm + new tools/<name>.rs following the same
pattern; also add a `Tool::new(...)` entry in `list_tools`.
API shapes confirmed from rmcp 1.6 source:
- Content = Annotated<RawContent>; text via `Content::text(s)`; pattern
match via `&content.raw` → `RawContent::Text(t)` → `t.text`
- CallToolResult::success(Vec<Content>) / ::error(Vec<Content>)
- ListToolsResult::with_all_items(Vec<Tool>)
- schema_for_empty_input() from rmcp::handler::server::common

KebabHandler implements rmcp::ServerHandler::get_info — returns
serverInfo (name="kebab", version from CARGO_PKG_VERSION) and
capabilities.tools. KebabAppState wraps Config in Arc for cheap clone
into per-request task scope. serve_stdio entry builds a multi-thread
tokio runtime and runs the server until client closes the stream.
rmcp 1.6 API used:
- rmcp::ServerHandler trait (re-exported from handler::server)
- ServerInfo::new(caps).with_server_info(impl) builder (not struct-init:
InitializeResult/Implementation are #[non_exhaustive])
- ServerCapabilities::builder().enable_tools().build() — builder macro
generated, confirms the plan-literal pattern works
- Implementation::new(name, version) — non-exhaustive constructor
- rmcp::transport::stdio() returns (tokio::io::Stdin, tokio::io::Stdout)
tuple; tuple impls IntoTransport via AsyncRead+AsyncWrite blanket
- handler.serve(transport).await → RunningService<RoleServer, H>
(ServiceExt::serve, returns Result<_, ServerInitializeError>)
- service.waiting().await → Result<QuitReason, JoinError>
- serve_stdio is plain fn wrapping a manually-built tokio runtime
(avoids nested-runtime hazard if kebab-cli ever gains its own rt)
Tools wire-up lands in subsequent tasks (one tool per task).
