Added `pub mod memory;` after `pub mod llama;` in `lib.rs`. In `config.rs` added `#[serde(default)] pub memory: Memory,` after `pub broker: Broker,` in `Config`, the `Memory` struct (empty socket means the default under `home`) after `struct Config`, and `memory_socket()` before `channel_socket`. In `baseline.rs` changed the module comment ("the memory block and core tool schemas"), removed the `Core(PathBuf, io::Error)` variant and its Display arm (the `#core-memory-unreadable` one), and replaced `assemble` whole with `assemble` (calls `assemble_with(cfg, registry, "")`) and `assemble_with` (system trimmed, then a blank line and the trimmed block when non-empty). In `tools.rs` added `m5a()` before `core_schemas`: `m3a().entries` with `recall` (id 1) and `memory` (id 2) inserted as core. In `channel.rs` added `use crate::memory::MemorySource;`, the `memory: Box` field on `Context` and a last `memory` param on `Context::new`; in `handle` replaced the `Baseline::assemble` call with `ctx.memory.block().and_then(|block| Baseline::assemble_with(...))`, and after `drop(held)` in step 5 added the best-effort `ctx.memory.updated(&turn.session)` for a finished turn. In `main.rs` imported `MEMORY_WAIT, MemoryPort` and built `MemoryPort::new(cfg.memory_socket(), MEMORY_WAIT)` with `Registry::m5a()`. Appended the memory sentence to `config/system.md`. Filled the three `todo!()`s in `memory.rs`: `MemoryPort::ask` (connect, set read and write timeouts to `self.wait`, write the final id-1 envelope, read it — `Ok(its msg)`; every error `format!("memoryd at {}: {e}; {UNAVAILABLE}", socket)`); `block` (`MemoryBlock(Empty)` -> `MemoryBlockReply.reply.text`; `Error` -> `memoryd: {detail}; {UNAVAILABLE}`; else `wrong message; {UNAVAILABLE}`); `updated` (`SessionUpdated` -> `Ok(())`; `Error` -> `memoryd: {detail}`; else `wrong message`). `cargo fmt --all`; `memory` 4 and `pointers` 7 passed, the full loopd suite green; `make gate` printed `gate: ok` on the first run. No new dependency, so `Cargo.lock` is unchanged. | ? | | M5a/12-brokerd-memory-port | 2026-09-24 | done | 2 | fail | none | Copied the skeleton `crates/brokerd/src/memory_port.rs` and the test `crates/brokerd/tests/memory_port.rs` into place, a new `support/rig.rs` (its `Config` literal gains `memory: Default::default()`), and appended the `memoryd-unreachable` runbook entry. Added `pub mod memory_port;` after `pub mod ledger;` in `lib.rs`. In `policy/mod.rs` added the private `state` field to `Decision`, the `state()` accessor after `request()`, and threaded `state` through the `decide`/`redecide` literals (both already take it as a parameter). In `runner.rs` widened the `use` to `::{Decision, Label, SessionState}`; `RunSpec` gained a `state` field and `state()`; `Runtime` gained a default `run_labelled` that calls `run` and returns no label so existing runtimes are unchanged; `run` now calls `run_labelled` and keeps the stricter of the found label and the grant's (higher class via `.max`, untrusted if either). In `container.rs` added the `IN_MEMORYD` const and a `run` guard that refuses a memory tool before spawning. In `config.rs` added the `Memory` struct before `default_podman`, the `memory` field on `Config`, and `memory_socket()` before `audit_dir`. In `main.rs` imported `MemoryPort`/`Routed`/`MEMORY_WAIT` and wrapped the runtime in `Routed { memory: MemoryPort::new(cfg.memory_socket(), MEMORY_WAIT), other }`. Filled `MemoryPort::ask` (build the `MemoryCall` with the spec's session/call/tool/canonical arguments and the state's taint/untrusted, connect, set read and write timeouts to `wait`, write the final envelope, read it — `Some` only on a `Message::ToolResponse`, else `None`); `MemoryPort::run_labelled` (`Result` -> `Ok((output, Some(label)))`, `Failed` -> `Failed`, anything else or `None` -> `Unreachable`); `Routed::run_labelled` (memory tools to `memoryd`, everything else to `other`). `cargo fmt --all`; `memory_port` 5 passed and the full brokerd suite green; `make gate` printed `gate: ok` on the second run — the first failed on rustfmt import order in `memory_port.rs`, fixed by re-running `cargo fmt --all`. No new dependency, so `Cargo.lock` is unchanged. | ? | | M5a/11-brokerd-memory-tools | 2026-09-24 | done | 2 | pass | none | Copied the skeleton `crates/brokerd/src/builtin.rs` and the tests `crates/brokerd/tests/memory_tools.rs` and a new `grants.rs` (the empty-directory test now asserts `matchable()` sees the two built-ins rather than comparing to an empty set), and added `pub mod builtin;` after `pub mod broker;` in `lib.rs`. Filled `builtin::grants`, the only `todo!()`: for each `(id, text)` of `[("builtin-memory", MEMORY), ("builtin-recall", RECALL)]`, `toml::from_str::` and `sha256(text.as_bytes())` each error as a `GrantProblem { file: id, line: None, problem: e }`, then a `LoadedGrant { id, grant, sha256 }`, collected into `Result, GrantProblem>` (first error wins); the tests failed on the `todo!()` first, then passed. In `args.rs` added `use proto::{MemoryArgs, RecallArgs}`; the `Recall`/`Memory` variants of `ToolName` with their `parse`/`as_str` arms, the `is_memory` method, and the `Recall`/`Memory` variants of `ToolArgs` with their `tool`/`canonical_json`/`parse` arms. In `grants.rs` added the `builtin` field to `GrantSet`, the `builtin` join at the end of `from_grants` (only when the set passed), `matchable`, Rule 2b for ids starting `builtin-`, and the built-in sentence for a memory tool in `check_grant`. In `policy/matching.rs` matched against `matchable()` and gave the memory tools a constraint-free `covers` arm; in `runner.rs` routed them to no mounts/egress; in `config.rs` gave them the read_file time limit. `cargo fmt --all`; `memory_tools` 4 and `grants` 17 passed; the full brokerd suite green; `make gate` printed `gate: ok` on the first run.

Filled the functions the skeleton left as `todo!()`: `start` (open the loop, broker and admin sockets, a `Running { listeners, memoryd }` and a sender that prints the three addresses to stdout); `Running::run` (spawn an accept thread per listener, each clone the shared `memoryd` and the sender, loop `incoming()`, spawn a connection thread per stream and log a spawn failure as "memoryd: cannot start a thread: ", an incoming error sends "a listener failed: " and returns); `connection` (read the first frame, match on `MemoryCommand` — `Block` -> `block`, `SessionUpdated` -> `session_updated`, `Call` -> `call`, any other kind, a closed connection, a parse error or a frame past `MAX_FRAME` refused with the right sentence); `block` (session must not be `Refused`, `journal::block` the count, return the reply or the refusal as `Block`); `session_updated` (session must not be `Refused`, `journal::log` the new content, return the reply); `call` (session must not be `Refused`, build the `Context` from session/call/taint/untrusted, `Memory::call` the tool, `ToolResponse::Result` with the class and untrusted flags and text cut to `TOOL_RESPONSE_MAX` chars, `ToolResponse::Failed` with the sentence); `memory` (session must not be `Refused`, `memory::render` the file, the reply with the class and untrusted, or the refusal); `index_notes` (session must not be `Refused`, `index::index_notes` the text, log a `Reindexed` with the counts and problems, return the reply); `reindex` (caller must be the owner, `index::rebuild` the index, log a `Reindexed`, return the reply); `admin` (caller must be the owner, the tool `index`/`recall`/`memory` routed to `index::index`, `index::session_logs`/`index::logs`, or the memory file, every other tool "memoryd runs only recall and memory", a count parsed as usize with the "not a number" and "too large" errors). `cargo fmt --all`; the eight `serve` tests passed; `make gate` printed `gate: ok` on the second run — the first failed on rustfmt import order in the `use proto::{..}` line and a trailing semicolon, fixed by re-running `cargo fmt --all`.
