From 82b7898e842ae7fb8ec2ce5c89877ff2813578b6 Mon Sep 17 00:00:00 2001 From: Kyle Isom Date: Sun, 27 Sep 2026 23:22:37 -0700 Subject: [PATCH] M5c-1 plan: task 01, the speaker, SessionUpdated's turn, the session-state messages Task 01 changes bxcore's wire and log types for M5c-1: Turn.speaker and LogRecord::User.speaker (optional, skipped when None, so old frames and logs keep their bytes), SessionUpdated.turn (required, refused when missing), and the new SessionState / SessionStateReply messages. The other crates only construct the new fields (speaker: None, turn: 0) and brokerd's kind() names the two new kinds; later tasks give them values. 20 given files. Checks, against a reference at 7b40686 with its own build directory: - every "before" block found exactly once at 7b40686 (and at master, which changed no crate since); - step 2's failures as the task names them: two strict tests, fifteen test targets with E0559/E0560/E0432/E0599 only; - make gate: gate: ok, 1130 tests (1122 + 8); /tmp unchanged around it; - replay from the task text in a fresh worktree of 7b40686 with its own target/: crates/ byte-identical to the reference, gate ok, 1130; removed; - 23 mutations: 21 caught; the two that drop `default` from an Option field cannot change behaviour (serde reads a missing Option as None); - no chat-template tag whole in the task or the given files; lines over 100 characters only in tables, fixtures and verbatim strings.

It works the same on a field of a + struct (`Turn`) and on a field of a variant of an internally tagged enum (`LogRecord::User`); + `ToolResponse::Denied`'s `detail` already uses it. (`serde` reads a missing `Option` field as + `None` even without `default`; the attribute says so in so many words, as `detail`'s does.) +- **Why `speaker` is optional.** A missing speaker means "not synced", which is the safe way to + be wrong. And `loopd` replays each session's log byte for byte to the inference server: a log + written before M5c must read as it is, and a record without a speaker must be written with the + bytes it had before. The given `neutralise_replay.rs` and `session.rs` check those bytes. +- **Why `turn` is required.** A `u64` field without `#[serde(default)]` is required: decoding a + `session_updated` without it fails with ``missing field `turn` ``. A default would read a + missing turn as turn 0, and `memoryd` would later record the wrong turn. `loopd` and `memoryd` + are built from this one workspace and deployed together, and `SessionUpdated` refuses unknown + fields, so an older reader refuses the new frame anyway. So: no `#[serde(default)]`, no + `skip_serializing_if`. The same holds for `SessionStateReply`'s `class` and `untrusted`: a + default would read a missing field as a clean session. `PROTOCOL_VERSION` does not change. +- **The kinds.** `Message` is `#[serde(tag = "kind", content = "body", rename_all = + "snake_case")]`, so the variants `SessionState` and `SessionStateReply` are written as + `"kind":"session_state"` and `"kind":"session_state_reply"` with no attribute of their own. +- **No checks on the name.** `bxcore` does not check a speaker's name. `memoryd` checks it + against Honcho's pattern in a later task (M5c spec, section 3). A given test sends + `first.last` and expects it back as it is. +- **Two types named `SessionState`.** `brokerd` has its own `brokerd::policy::SessionState` + (`taint`, `untrusted`). The new `bxcore::SessionState` is a message. They do not meet in this + task: `broker.rs` names the new one only as the pattern `Message::SessionState(_)`, which needs + no import. Do not add `SessionState` to any `use` line in `brokerd`. +- **Placeholders.** `turn: 0` in `loopd` is harmless until task 02: `memoryd` answers + `SessionUpdated` by reading the session's log, and nothing reads `turn` before task 09. +- The calls and attributes the edits use: + + | Item | What it does | + |---|---| + | `#[serde(default, skip_serializing_if = "Option::is_none")]` | on `speaker` (W3, L1): missing reads as `None`; `None` is not written | + | `#[serde(deny_unknown_fields)]` | on each new struct (M1): an unknown key is refused, as on every message | + | `LogRecord::User { time, content, .. }` | a pattern that ignores the fields it does not name (I1) | + +## The edits, exactly + +Nothing else in these files changes.

Run the gate.** `cargo fmt --all`, then `make gate`, with a shell timeout of 600000 ms. + Expected last line: `gate: ok`, with 1130 tests: 1122 before this task, plus 8 new ones (two + in `bxcore/tests/turn_wire.rs`, three in `memory_wire.rs`, one in `records.rs`, one in + `strict.rs`, one in `brokerd/tests/broker.rs`; the other new versions keep their counts). +- [ ] **7. Log and commit.** Add your row to `docs/implementer-log.md`; its Task cell is + `M5c1/01-wire-speaker-state`. `git status --short` lists the ten sources, the sixteen replaced + test files and your log as modified, and the four new fixtures. Stage with + `git add crates/bxcore crates/brokerd crates/gatewayd crates/bxctl crates/loopd crates/memoryd 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 1130 tests. +- `git diff HEAD~1 --stat` lists only the ten source files of "Modify", the twenty copied files + and `docs/implementer-log.md`. + +## Stop and report if + +- A "before" block of any edit is not in its file exactly as shown, or is there more than once. +- Step 2 shows a different result: other tests failing in `strict`, other test targets, or an + error of another kind. +- Step 4's build fails anywhere other than the six places it names. +- After step 3 or 4, a test fails. Do not change a test or a fixture: stop, and give the failing + tests' names and their messages. +- The fix seems to need a change anywhere else: another source file, a test under + `crates/gatewayd/tests`, a default for `turn`, `class` or `untrusted`, or a check on the + speaker's name. It does not; stop and say why you think so. +- A test in `inferproxy` or `toolkit` fails in the gate: check once whether it fails without your + change, then stop and report both results. +- The gate passes with a count other than 1130. +- A comment in an edit does not fit the code under it.
