backends/ollama.rs implements the Backend trait against Ollama's
POST /api/chat (messages + tools arrays, message.tool_calls response) --
never mesh/listener/assist.rs::call_ollama's older single-shot prompt
endpoint, which has no tool-calling support at all. Ollama's per-call
tool-call ids (absent on the wire) are synthesized; its already-parsed
function.arguments object is passed through without a second string-parse
(the OpenAI-shape normalization would be wrong here). Every request sets
an explicit generation-length cap and runs non-streaming.
model_supports_tools queries Ollama's /api/show and caches the answer for
the process lifetime, turning AI-SPEC's [ASSUMED] note about
qwen2.5-coder's tool capability into a runtime fact: a non-tool-capable or
unreachable Ollama falls through to Claude with a logged reason, never a
silent tools-free degrade.
select_backend (backends/mod.rs) is now async and reuses the existing
detect_ollama() probe (mesh::assistant, bumped to pub(crate) for this
reuse) rather than re-probing. A new FallbackChain wraps the Ollama leg so
a transport error mid-turn falls through to Claude for that same call
instead of failing the turn outright.
13 new tests under assistant::backends::{ollama,}::tests::, exercised
against a local hyper-based HTTP stub (no mock-HTTP crate exists in this
workspace). Full assistant:: suite: 42/42 (29 baseline + 13 new).

Executor stopped deliberately for a session restart (bypass-permissions relaunch).
Executor's final report: 'cargo test assistant confirm-gate suite 28/28 green,
individual nonce test passes; committing Task 1 next — first verify the
tools.rs/grants.rs/backends diffs are formatting-only.'
Task 1 (D-07/D-11 confirm gate, backend) is implemented and test-green but this
checkpoint is verbatim-uncommitted-state, NOT the reviewed atomic Task 1 commit:
continuation executor should verify diffs, then reset --soft or commit-on-top
into proper feat(13-08) task commits. Task 2 (ToolConfirmModal.vue trusted
chrome, Chat.vue + contextBroker.ts wiring) is partially built, tests written.

D-01/D-02/D-06 tracer slice: a new crate::assistant module (CallerScope,
PermissionCategory, ToolExecCtx, chat()) runs a multi-turn tool-calling loop
(run_loop/execute_tool, MAX_TURNS=8) against a curated single-tool registry
(system_disk_status, hand-written JSON Schema — no schemars) via a Claude
Messages API backend. execute_tool is the single choke point: unknown tools
are refused not ignored, D-16 category grants are re-checked even though the
system prompt already omits ungranted tools, and every real tool dispatches
through the SAME handle_system_disk_status RPC handler every other
authenticated caller uses (assistant_dispatch_tool bridge in
api/rpc/assistant_chat.rs) — never an AI-only backdoor.
assistant.chat is registered in dispatcher.rs as a single guarded
`m if m.starts_with("assistant.")` arm reached only after the existing
session-cookie + CSRF + role.can_access() gate in api/rpc/mod.rs — asserted
directly by assistant_methods_require_session against the live
UNAUTHENTICATED_METHODS list (visibility only widened to pub(crate) for that
assertion; the list's contents are untouched, per the Phase-10 hard
constraint).
Key read from data_dir/secrets/claude-api-key — the same path
mesh/rpc/mesh/assistant.rs already probes — never a second key location.
