+# M5c-2 task 04: `loopd` declares `ask_memory` and waits 180 s for it
+
+**Branch:** `m5c2`. Check it: `git branch --show-current` prints `m5c2` and `git status --short`
+is empty; otherwise stop. Never switch branch.
+**Commit subject:** `loopd: ask_memory as a core tool, and a wait of its own on brokerd`
+**Log row:** the Task cell is `M5c2/04-loopd-ask-memory`.
+
+## Goal
+
+Tasks 01 to 03 gave `bxcore` the arguments of `ask_memory` and taught `brokerd` to decide it and
+hand it to `memoryd`. 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. No epoch code is needed.
+
+## Every place that changes
+
+This is the complete list.
+
+| Place | What happens there |
+|---|---|
+| `crates/loopd/src/memory.rs` | `ASK_MEMORY`; `ask_memory_schema()` (edits S1, S2) |
+| `crates/loopd/src/tools.rs` | `Registry::m5c()`; `m5a()`'s comment no longer says `loopd serve` uses it (edits T1, T2) |
+| `crates/loopd/src/main.rs` | `Registry::m5c()` instead of `Registry::m5a()` (edit N1) |
+| `config/system.md` | the last sentence (edit Y1) |
+| `crates/loopd/src/broker_port.rs` | `ASK_MEMORY_WAIT`; the field `ask_timeout`; `with_ask_wait`; `timeout_for`; `call` uses `timeout_for` (edits P1 to P7) |
+| `crates/loopd/tests/ask_memory_tool.rs`, `broker_port_ask_wait.rs` | new, given |
+| `crates/loopd/tests/device.rs` | new version, given: the token-budget check measures the `m5c()` baseline |
+| everything else | **no change**: not `baseline.rs`, not `turn.rs`, not the other tests, no `Cargo.toml` |
+
+## Files
+
+- Copy, from `docs/plans/M5c2/files/` (the same path under it): the new tests
+  `crates/loopd/tests/ask_memory_tool.rs` and `crates/loopd/tests/broker_port_ask_wait.rs`, and a
+  **new version** of `crates/loopd/tests/device.rs` (it replaces the file in the tree).
+- Modify: `crates/loopd/src/memory.rs`, `crates/loopd/src/tools.rs`, `crates/loopd/src/main.rs`,
+  `crates/loopd/src/broker_port.rs`, `config/system.md`, `docs/implementer-log.md`.
+- Do not touch: any other file.
+
+## Facts you need
+
+- **`bxcore::memory::ASK_MEMORY`** is `"ask_memory"` (task 01). `loopd`'s own `ASK_MEMORY` is
+  defined as that constant (edit S1), so the two cannot differ; `loopd` depends on `bxcore`
+  already.
+- **The schema's JSON.** `serde_json::json!` sorts object keys (the crate is built without
+  `preserve_order`), so the request carries the keys in alphabetical order whatever order the
+  source writes them in. 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. This table is complete; nothing from a crate's source (the Cargo
+  registry, `~/.cargo/registry`) is needed or allowed.
+
+  | Item | Where |
+  |---|---|
+  | `serde_json::json!` | S2, as in `recall_schema` |
+  | `crate::llama::ToolSchema { name, description, parameters }` | S2, as in `recall_schema` |
+  | `Entry { schema, core }`, `Vec::insert(index, value)` | T2, as in `m5a` |
+  | `Duration::max(self, other) -> Duration` | P4 |
+  | `str == &str` | P4: `tool == crate::memory::ASK_MEMORY` |
+
+## The edits, exactly
+
+Nothing else in these files changes. Each quoted "before" block occurs exactly once in its file
+when its turn comes (make them in order). Keep the fields in the order shown.

+
+## Steps
+
+- [ ] **1. Copy the given tests.** From the repository root, three commands:
+
+  ```sh
+  cp docs/plans/M5c2/files/crates/loopd/tests/ask_memory_tool.rs crates/loopd/tests/
+  cp docs/plans/M5c2/files/crates/loopd/tests/broker_port_ask_wait.rs crates/loopd/tests/
+  cp docs/plans/M5c2/files/crates/loopd/tests/device.rs crates/loopd/tests/
+  ```
+
+  Then `git status --short` lists `crates/loopd/tests/device.rs` as modified and the two other
+  files as new.
+- [ ] **2. See them fail.** `cargo build --tests --keep-going -p loopd`, with a shell timeout of
+  600000 ms: three test targets do not compile, with 14 errors in all, each about a name this
+  task adds:
+  - `ask_memory_tool`, 4: one `E0432` (``unresolved imports `loopd::memory::ASK_MEMORY`,
+    `loopd::memory::ask_memory_schema` ``) and three `E0599` (``no associated function or
+    constant named `m5c` found for struct `Registry` ``);
+  - `broker_port_ask_wait`, 9: one `E0432` (``unresolved import
+    `loopd::broker_port::ASK_MEMORY_WAIT` ``), five `E0599` (``no method named `timeout_for` ``)
+    and three `E0599` (``no method named `with_ask_wait` ``);
+  - `device`, 1: the same `E0599` for `m5c`.
+  Every other target compiles.
+- [ ] **3. The edits.** Make edits S1, S2, T1, T2, N1, Y1 and P1 to P7, in order. `cargo check
+  -p loopd` prints no error and no warning. Then
+  `grep -n 'self.timeout' crates/loopd/src/broker_port.rs` prints three lines: two in
+  `timeout_for`, and P5's `let timeout = self.timeout_for(&request.tool);`.
+- [ ] **4. The tests.** With a shell timeout of 600000 ms, every test passes: 6 in
+  `ask_memory_tool`, 4 in `broker_port_ask_wait`, and the others as before (15 in `broker_port`, 2
+  in `broker_port_bad`, 2 in `broker_port_cap`, 4 in `memory`, 6 in `turn_broker`):
+
+  ```sh
+  cargo test -p loopd --test ask_memory_tool --test broker_port_ask_wait --test memory \
+    --test broker_port --test broker_port_cap --test broker_port_bad --test turn_broker
+  ```
+- [ ] **5. Check.** Two commands:
+  - `git diff --stat` lists exactly the five files of "Modify" (not the log yet) and
+    `crates/loopd/tests/device.rs`.
+  - `git diff config/system.md | grep -c '^[-+]You are'` prints `2`: one line removed, one added.
+- [ ] **6. Run the gate.** `cargo fmt --all`, then `make gate`, with a shell timeout of 600000 ms.
+  Expected last line: `gate: ok`. The test count is the passed total of `cargo test --workspace`
+  plus one, for the ignored `end_to_end` test that the gate runs on its own: **1394** after this
+  task, 1384 before it; the 10 new ones are the tests of `ask_memory_tool.rs` (6) and
+  `broker_port_ask_wait.rs` (4). To count, add up the `N passed` of every `test result:` line
+  the gate's `cargo test --workspace` printed, and add 1. Never run the gate again only to count.
+- [ ] **7. Log and commit.** Add your row to `docs/implementer-log.md`; its Task cell is
+  `M5c2/04-loopd-ask-memory`. `git status --short` lists the five edited files, `device.rs` and
+  your log as modified, and the two new tests. Stage with
+  `git add crates/loopd config/system.md docs/implementer-log.md Cargo.lock`, then commit as
+  `AGENTS.md` says. `Cargo.lock` does not change in this task; the `git add` is harmless.
+
+## Done when
+
+- `make gate` prints `gate: ok` with 1394 tests.
+- `git diff HEAD~1 --stat` lists only the five edited files, the three test files of step 1 and
+  `docs/implementer-log.md`.
+
+## Stop and report if
+
+- The branch check at the top fails.
+- A "before" block is not in its file exactly as shown when its turn comes, or is there more
+  than once. P3's and P4's blocks differ in their last lines (`log: Box::new(...)` and `log,`):
+  each is in the file once.
+- Step 2 shows a different result: other targets failing, or other errors.
+- `cargo check` in step 3 prints an error or a warning, or the `grep` prints other lines. Quote
+  them, and stop.
+- A test fails in step 4. Do not change a test: stop, and give the failing tests' names and
+  their messages.
+- The fix seems to need a change anywhere else: `baseline.rs`, `turn.rs`, `config.rs`, a
+  configuration key, a test other than the three given. It does not; stop and say why you think
+  so.
+- A test outside the given files fails in the gate: check once whether it fails without your
+  change (`git stash -u`, run it, `git stash pop`), then stop and report both results.
+- The gate passes with a count other than 1394.
+- A comment in an edit does not fit the code under it. Quote it and stop.
+
+## What the given tests pin
+
+Each of these changes to the finished code makes at least one given test fail (19 tried, all
+caught): `ask_memory` in another place in `m5c()`, or not core; `main.rs` using `m5a()`; the
+schema's `maxItems` changed or left out, a `reasoning` property added, `workspaces` required,
+or its description changed; `system.md`'s old sentence; `ASK_MEMORY_WAIT` changed; the timeout
+ignored for `ask_memory`, or the shorter of the two used; `timeout_for` ignoring the tool, or
+giving every tool `ask_memory`'s wait; the first deadline or the extension after a pending
+frame using the configured timeout instead of the call's; `with_ask_wait` doing nothing; `new`
+or `with_log` giving `ask_memory` the configured timeout by default.
