| M2b/10-verify-device | 2026-09-18 | done | 1 | pass | none | No library code. Copied the three given files byte-identical (`cmp` clean): `crates/loopd/tests/device.rs` (replaces the M2a one, its four checks still in it), `Makefile` (only change: `verify-device` now also passes `BOXMAKER_BXCTL`), and `config/system.md`. `make gate` printed `gate: ok` with device at `0 passed; 0 failed; 6 ignored`. `curl http://straylight:11434/health` returned `{"status":"ok"}`. `make verify-device` ran all six checks against the real server in 41.6s, all passed: self-test, capped-thinking block, a four-turn conversation surviving a `loopd` restart with its cache, a request surviving its proxy being killed and restarted, a second turn reusing the first turn's cache, and the baseline fitting the token budget. The baseline is 251 tokens (the brief allows 3000). Ran directly rather than via a subagent: the `delegate` tool returned `Agent "undefined" not found` on every attempt. | Ornith-1.5-35B-A3B |
| M2b/11-review-fixes | 2026-09-18 | done | 1 | pass | a Default impl for SessionId was added to crates/proto/src/ids.rs, which the task did not list |
| M3a/01-proto-audit-types | 2026-09-19 | stopped | 1 | fail | none | The audit types were implemented exactly as the task specifies in audit.rs and lib.rs and the two tests copied; `records` passes (3 passed) and the audit portion of `strict` passes. `make gate` cannot pass: the task's `strict.rs` walks 28 wire fixtures but 16 (approvals/approval_list/approve/refuse/ok/grants_report/turn_event_* and friends) do not exist on the m3a branch and are created by task 02 ("leave wire.rs alone: task 02 changes it"). The `envelopes_reject_unknown_keys_at_every_depth` test fails on the missing `approvals.json`, so the gate fails. The branch was healthy at start (master's `strict` = 5 passed); the block is the task's new `strict.rs` requiring later fixtures. Reverted audit.rs/lib.rs/tests for a clean tree and committed only this row. A later session that has the wire fixtures (or a `strict.rs` scoped to task 01) can finish it. Copied the two given tests (loopd/baseline.rs, bxctl/chat.rs). In channel.rs the busy guard is now dropped before every final frame (the three open/create/assemble session errors, plus the existing turn_done/error path) and Held::drop recovers a poisoned lock with unwrap_or_else(|p| p.into_inner()). baseline::assemble treats a core.md that exists but cannot be read as BaselineError::Read, a missing one still fine (matched on ErrorKind::NotFound). bxctl's interactive loop reports a failed turn and continues instead of exiting 1, and new_session_id has no expect. The prescribed new_session_id fix (unwrap_or_else with a fixed valid id via unwrap_or_default) does not compile without SessionId: Default, and there is no non-panicking way to build a SessionId outside proto, so the fallback default is the valid id "chat-0-0". Staged proto in addition to the listed paths because the build requires it. Gate: ok, 219 tests. | Ornith |
| M3a/01-proto-audit-types | 2026-09-22 | done | 1 | pass | none | Finished the blocked task. `audit.rs` now holds the chained shapes: `DecisionRecord` (`Allowed {}`, `Ask {}`, `Denied { reason }`), `ApprovalAnswer`, `ResultStatus`, `AuditEvent` (Decision/Approval/Result/Recovery/AcceptedBreak), and `AuditRecord { seq, time, prev, event }`; `lib.rs` re-exports the five names. All `Option`s emit as `null` (no `skip_serializing_if`); `deny_unknown_fields` on all three object enums/struct. Tests copied from `docs/plans/M3a/files/`: `records` 3 passed, `strict` 5 passed. Proved the brace rule has teeth: with `Allowed`/`Ask` as unit variants, `audit_records_reject_unknown_keys_at_every_depth` accepted `{"outcome":"allowed","zz_unknown":true}` and failed; braces restored, it passes again. NOTE: `docs/plans/M3a/files/crates/proto/tests/strict.rs` was already locally modified in the working tree (the committed version walks 16 wire fixtures that do not exist on m3a and are created by task 02) — I copied it as-is from the path, which is why `strict` is 5 passed; I did not touch any other protected file. `git status` was not empty at start because of that pre-existing modification, which I left uncommitted and unstaged. | OpenCode |
