 | Task | Date | Status | Gate runs | First gate | Deviations | Notes | Model |
 |---|---|---|---|---|---|---|---|
+| M5c1/02-loopd-speaker-turn | 2026-09-28 | done | 2 | pass | none | Copied five files from `docs/plans/M5c1/files/`: `speaker_turn.rs` (new) and new versions of `memory.rs`, `turn_broker.rs`, `end_to_end.rs` and `support/turn.rs` (skipped the older `memory.rs-task01`). Step 2 showed exactly the named failures: eight non-compiling test targets (end_to_end, limits, memory, neutralise, neutralise_replay, speaker_turn, turn, turn_broker) with E0061 for `run_turn` and `updated`, E0282 on the closure, E0050 and E0599 for `turns`. Made the edits exactly as the task gives: S1 `Session::turns` counting `User` records in `records` via `matches!` and `u64::try_from(...).unwrap_or(u64::MAX)`, placed before `last_usage`; M1 the trait `updated` gains `turn: u64`, M2 `NoMemory` and M3 `MemoryPort` pass it (the `turn: 0` placeholder and its comment dropped for `turn`); T1 `run_turn` gains `speaker: Option<&str>` after `content` with the doc comment, T2 logs `speaker: speaker.map(str::to_string)` (as it came, not checked, not neutralised, `None` not written); C1 passes `turn.speaker.as_deref()` to `run_turn`, C2 passes `session.turns()` to `updated` (the comment now says the number is this turn's, a failed turn not told but its logged message still counts). `baseline::messages` untouched, the request is the same with and without a speaker. Step 7 all pass: the grep for `turn: 0`/`speaker: None` prints nothing, `git diff --stat -- crates/loopd/src` lists exactly channel.rs/memory.rs/session.rs/turn.rs (baseline.rs absent), the other-crates diff is empty. After the edits `cargo check -p loopd` is clean, `speaker_turn` 8 passed, every loopd suite passes. `make gate` printed `gate: ok` with 1138 tests (1130 before plus the 8 of `speaker_turn.rs`). No new dependency, so `Cargo.lock` is unchanged. | ornith-1.5-35b-a3b |
 | M5c1/01-wire-speaker-state | 2026-09-28 | done | 1 | pass | none | Changed the types in `bxcore` only, as the task says: `Turn` and `LogRecord::User` gain `speaker: Option<String>` (optional, `serde(default, skip_serializing_if = "Option::is_none")`, so a frame or log line without it reads `None` and `None` is not written); `SessionUpdated` gains `turn: u64` (required, no default), plus the two new messages `SessionState { session }` and `SessionStateReply { class, untrusted }` (both fields required). Copied the 20 given files from `docs/plans/M5c1/files/` (4 new fixtures, 16 replaced test files, the loopd `memory.rs` and bxctl `chat.rs` being the `-task01` versions). Step 2 showed exactly the named failures: `strict` `envelopes_reject_unknown_keys_at_every_depth` on `turn_speaker.json` and `speaker_log_records_reject_unknown_keys_at_every_depth` on `session_speaker.jsonl:2`, and 15 non-compiling test targets with E0559/E0560/E0432/E0599. Made every edit exactly as the task gives (W1-W3, L1, M1, X1 in bxcore; B1-B2 in brokerd; G1, C1, T1, U1, I1 in gatewayd, bxctl, loopd twice, memoryd), the placeholders `speaker: None` / `turn: 0` left in place. After the edits `cargo test -p bxcore` every suite passes (turn_wire 9, memory_wire 5, records 4, strict 6) and `cargo test -p brokerd -p gatewayd -p bxctl -p loopd -p memoryd` every suite passes. Step 5 checks all pass: `grep -c 'serde(default' crates/bxcore/src/wire.rs` prints 2, `git diff --stat -- crates/gatewayd/tests crates/inferproxy crates/toolkit` prints nothing, `git diff --stat -- crates/*/src` lists exactly the ten source files. `make gate` printed `gate: ok` with 1130 tests (1129 in `cargo test --workspace`, plus the 1 ignored `end_to_end` the gate runs separately with `BOXMAKER_BROKERD` set; the first gate run's `end_to_end` was the only flake and it passes once the env var is set). No new dependency, so `Cargo.lock` is unchanged. | ornith-1.5-35b-a3b |
 | M5b/14-runbook | 2026-09-27 | done | 1 | pass | none | Only `docs/runbook.md` changed. R1 in `memory-write-refused` under **Fix.**: the two-line sentence about narrowing the rule replaced with the same sentence pointing at [`sanitizer-rules`](#sanitizer-rules) instead of "the M5b spec's section 6.5". R2 in `memory-write-flagged` under **Fix.**: the two-line "narrow it as the M5b spec's section 6.5 says" replaced with the same sentence pointing at [`sanitizer-rules`](#sanitizer-rules). Verified before appending: `grep -c "section 6.5"` printed 0. Appended `docs/plans/M5b/files/runbook-sanitizer-rules.md` verbatim with `{ echo; cat ... } >> docs/runbook.md`; `grep -c '^## sanitizer-rules$'` printed 1 and `grep -c '(#sanitizer-rules)'` printed 2. `cargo fmt --all`; `make gate` printed `gate: ok` with 1118 tests (1117 in `cargo test --workspace`, plus the ignored `end_to_end` the gate runs). No code, so `Cargo.lock` unchanged. | ornith-1.5-35b-a3b |
 | M5b/13-instance-lock-rest | 2026-09-27 | done | 2 | pass | none | Made the other three daemons take the instance lock, `bxcore::instance` (task 12), the same way `loopd` and `inferproxy` do: before they touch their sockets each locks `<home>/run/<role>.lock` and holds it until the process ends. Copied the three new `instance.rs` tests and a new version of `crates/brokerd/tests/serve.rs` (the old second-instance test was gone) from `docs/plans/M5b/files/`. Step 2 showed exactly the named failures: brokerd `instance` failed on `the lock's line, and nothing else` (the second stopped at the audit lock with `brokerd is already running`) and `the lock file, mode 0600` (None vs Some(384)); `serve` 8 passed; memoryd and gatewayd `instance` each failed the same two shapes, each about 10 s. Made the edits exactly as the task gives: B1 the `use bxcore::instance;` import in brokerd main.rs, B2 the lock after the config loads and before `serve::start`; D1 the import in memoryd main.rs, D2 the lock after the config loads and before `serve::start`; G1 the combined `use bxcore::{instance, secrets};` import in gatewayd main.rs, G2 the `3b.` comment in `serve`, G3 the lock after the secret is read and before the state directory is made. `let _instance` binds each `InstanceLock` so it is not dropped at once. `cargo check` clean for each daemon; brokerd `instance` 2 / `serve` 8, memoryd `instance` 2, gatewayd `instance` 2 / `main` 5 pass. `grep -rn 'instance::lock(' crates/*/src` prints exactly five lines, one in each of brokerd, gatewayd, inferproxy, loopd, memoryd; `grep -rn 'runbook.md#already-running' crates/*/src` prints one line in bxcore; `git diff --stat -- crates/bxcore '*Cargo.toml'` prints nothing. `cargo fmt --all`; `make gate` printed `gate: ok` with 1118 tests (1113 before, minus 1 in the new brokerd `serve.rs`, plus 2 in each of the three new `instance.rs`). No new dependency, so `Cargo.lock` is unchanged. | ornith-1.5-35b-a3b |
