This task lets the model call it (M5c spec, section 9): + +- **The schema.** `ask_memory_schema()` in `crates/loopd/src/memory.rs`, beside + `recall_schema()`. It asks for exactly what `bxcore::AskMemoryArgs` reads: `question` + (required, a string) and `workspaces` (optional, an array of at most 2 strings). Its text is + short, because every core schema counts toward the baseline's 3,000-token budget: 378 + characters as the request carries it, against `recall`'s 403 and `memory`'s 868. +- **The registry.** `Registry::m5c()` is `m5a()`'s entries with `ask_memory`, core, after + `memory`. `loopd serve` (`main.rs`) uses `m5c()`. `m5a()` stays as it is, so the tests that use + it keep passing unchanged. +- **The system prompt.** `config/system.md`'s last sentence names both tools whose text comes + back from memory. +- **The wait on `brokerd`.** `BrokerPort` waits `[broker] timeout_ms` (120 s by default) for any + call. An `ask_memory` answer can take up to 170 s in `brokerd` (task 03), so `ask_memory` gets + `ASK_MEMORY_WAIT` = 180 s, or the configured timeout if that is longer. It replaces the + timeout for that call only, everywhere the call uses it: the first deadline, the write + timeout, and the extension after a pending frame. It is a constant; the tests shorten it with + `with_ask_wait`, as they shorten the pending cap with `with_pending_cap`. + +**Only new sessions see it.** A session saves its baseline (system prompt, memory block, tools +array) when it starts and sends that on every request (spec, section 9). Sessions started before +this is deployed keep their baseline and their cache, and never see `ask_memory` or the new +sentence; sessions started after it get both.

The given test compares the whole schema, byte for byte. +- **`maxItems`** is JSON Schema's limit on an array's length. `brokerd` refuses a third name + anyway, with a sentence telling the model to ask again (task 01). +- **Where `ask_memory` goes.** It is a core tool, but not one `loopd` answers itself: like + `recall`, a call is sent to `brokerd` as a `ToolRequest` whose `tool` is `"ask_memory"` + (`crate::tools::dispatch`, unchanged). So `BrokerPort::call` sees the tool's name in + `request.tool`. +- **How `BrokerPort` waits** (unchanged except for which value it uses): the whole call has one + deadline, `until`, set from the timeout before connecting; each frame read may take only what + is left of it. After a pending frame (an approval asked of the owner), `until` becomes the + expiry (capped) plus the timeout. The write timeout is the timeout too. Edits P5 to P7 put the + call's own `timeout` in those three places. +- **Struct update syntax.** `BrokerPort { ask_timeout, ..self }` takes `ask_timeout` from the + argument and every other field from `self`, as `with_pending_cap` does. +- **`Duration::max`**: `a.max(b)` is the longer of two `Duration`s (`Ord::max`). +- **`main.rs` needs no other change**: `BrokerPort::new` gives every port `ASK_MEMORY_WAIT`. +- **The given tests.** + - `ask_memory_tool.rs` (6 tests): the schema exactly, and shorter than `recall`'s; its + properties, required field and `maxItems` against `bxcore`'s `MAX_WORKSPACES`, and two + examples that `AskMemoryArgs` accepts; `m5c()`'s core tools in order, `m5a()` unchanged; + a baseline assembled from `m5c()` holding `ask_memory`; `main.rs` naming `Registry::m5c()` + and no other registry (no test runs `loopd serve` through a turn without a device and a + `memoryd`, so this test reads the source); the sentence in `config/system.md`. + - `broker_port_ask_wait.rs` (4 tests, about 5 s): the wait for each tool, the default, the + longer of the two; a fake `brokerd` that answers after 1.5 s reaching `ask_memory` with a + 20 s wait and not `recall` or `read_file` with a 300 ms timeout; a configured timeout + longer than `ask_memory`'s own wait kept; and the same after a pending frame. + - `device.rs`: one line changes: `the_baseline_fits_the_token_budget` assembles the baseline + from `Registry::m5c()`, not `m5a()`. It is an ignored test; the gate does not run it. The + design model runs it on the device (`make verify-device`). +- The items the edits use.
