 |---|---|---|---|---|---|---|---|
+| M5d1/02-loopd-session-epochs | 2026-10-02 | done | 1 | pass | none | Copied the given test `crates/loopd/tests/session_epochs.rs` (new). Step 2 (`cargo build --tests --keep-going -p loopd`) showed exactly the named failures: `session_epochs` with E0599 (`no method named epoch` / `carry` / `slot`) and E0433 (`NoCarry`); every other target compiled and the existing `session` tests still compiled. Made S1 (module doc naming `<epoch>.baseline.json` / `<epoch>.jsonl` and epochs after compaction), S2 (`SessionError` gains `NoCarry { path: PathBuf }`), S3 (its Display arm naming the damaged-log runbook pointer), S4 (`Session` gains `epoch`, `slot`, `carry`, `prior_users`, `prior_untrusted` in that order), S5 (`create` inits the five new fields, `slot` from the argument), S6 (whole `open`: `complete_epochs` picks the highest epoch with both files, `records` is the current log, `priors` walks every earlier complete epoch for user/untrusted counts and the epoch-1 carry, `max_call` over every epoch for `next_call`, `live_slot` from the current `SessionStart`), S7 (accessors `epoch` / `slot` / `carry`), S8 (`untrusted` = `prior_untrusted || any_untrusted`, `turns` = `prior_users.saturating_add(count_users)`), S9 (`log_path` to the current epoch's file plus helpers `complete_epochs`, `load_records`, `priors`, `carry_from`, `count_users`, `any_untrusted`, `max_call`, `live_slot`). `cargo check -p loopd` clean, no error or warning. `wc -l crates/loopd/src/session.rs` prints 402. `cargo test -p loopd --test session_epochs --test session` passes: 9 in `session_epochs`, 7 in `session`. `git diff --stat` lists only `session.rs`; `cargo fmt --all` changed nothing. `make gate` printed `gate: ok` with 1473 tests (1472 in `cargo test --workspace`, plus the 1 ignored `end_to_end`; the +9 over the 1464 before is exactly the tests of `session_epochs.rs`). No new dependency, so `Cargo.lock` unchanged. | ornith-1.5-35b-a3b |
 | M5d1/01-loopd-compact-config | 2026-10-02 | done | 1 | pass | none | Copied the given test `crates/loopd/tests/config_compact.rs` (new). Step 2 (`cargo build --tests --keep-going -p loopd`) showed exactly the named failures: `config_compact` with E0609 (`no field \`compact\` on type \`Config\``), E0599 (`no method named \`compact_prompt\``) and E0433 (`no variant or associated item named \`default\` for \`Compact\``); every other target compiled. Made the edits exactly as the task gives: C1 (new `Compact` struct after `Memory`, `#[derive(Debug, Clone, PartialEq, Deserialize)]` plus `#[serde(deny_unknown_fields, default)]`, fields in order `threshold: f64`, `summary_chars: usize`, `summarise: Vec<String>`, and `Default` = threshold `0.85`, `summary_chars` `4_000`, `summarise` `vec!["http_fetch".to_string()]`); C2 (`Config` gains `#[serde(default)] pub compact: Compact` after `memory`); C3 (`compact_prompt` after `channel_socket`, `self.baseline.system.with_file_name("compact.md")`). `cargo check -p loopd` clean, no error or warning. `cargo test -p loopd --test config_compact --test config` passes: 8 in `config_compact`, 11 in `config`. `git diff --stat` lists only `config.rs`; `cargo fmt --all` changed nothing. `make gate` printed `gate: ok` with 1464 tests (1463 in `cargo test --workspace`, plus the 1 ignored `end_to_end`; the +8 over the 1456 before is exactly the tests of `config_compact.rs`). No new dependency, so `Cargo.lock` unchanged. | ornith-1.5-35b-a3b |
 | M5c2/12-memoryd-serve-ask-memory | 2026-09-29 | done | 1 | pass | none | Copied the given test `crates/memoryd/tests/honcho_ask_serve.rs` (new). Step 2 (`cargo test --no-fail-fast -p memoryd --test honcho_ask_serve`) showed exactly the six named failures: every `ask_memory` answered with `memoryd runs only recall and memory`, and the hang test after its 10 s deadline (`the chat was never sent`). Made A1 (`ask.rs`: `NOT_CONFIGURED` before `NO_ANSWER`, the sentence letter for letter), E1 (`use bxcore::AskMemoryArgs;`), E2 (`use crate::honcho::ask;`), E3 (`call` gains the third arm `bxcore::memory::ASK_MEMORY => self.ask_memory(&call)` and the unknown-tool sentence becomes `memoryd runs only recall, memory and ask_memory`), E4 (new `ask_memory`: decode `AskMemoryArgs`, `args.check()?`, the `[honcho]`-less branch returns `NOT_CONFIGURED` labelled private and trusted, else `ask::ask` then `ask::answer`). `cargo check -p memoryd` clean, no error or warning. `cargo test` passes: 6 in `honcho_ask_serve`, 10 in `honcho_ask`, 4 in `honcho_recall_serve`, 4 in `serve_admin`, 8 in `serve`. Step 5 all pass: `git diff --stat` lists only `ask.rs` and `serve.rs`; `wc -l crates/memoryd/src/serve.rs` prints 456. `make gate` printed `gate: ok` with 1454 tests (1453 in `cargo test --workspace`, plus the 1 ignored `end_to_end`; the +6 over the 1448 before is exactly the tests of `honcho_ask_serve.rs`). No new dependency, so `Cargo.lock` unchanged. | ornith-1.5-35b-a3b |
 | M5c2/11-memoryd-serve-admin | 2026-09-29 | done | 1 | pass | none | Copied the given test `crates/memoryd/tests/serve_admin.rs` (new) and the new module `crates/memoryd/src/serve/admin.rs` (given whole, `reindex` and `admin` moved unchanged from `serve.rs`, `fn` becoming `pub(super) fn`). Step 1 (`cargo test -p memoryd --test serve_admin`) passed all 4 before the move. Made E1 (dropped `MemoryAdminReply`, `MemoryCommand`, `Reindexed` from the `bxcore` use in `serve.rs`), E2 (dropped `use crate::honcho::report;`), E3 (added `mod admin;` after `use crate::{journal, recall, review};`), E4 (deleted `reindex` and `admin` from the end of `index_notes` to the end of the file). `cargo check -p memoryd` clean, no error or warning. `cargo test -p memoryd` passes: 4 in `serve_admin`, every other suite as before. Step 5 all pass: `wc -l crates/memoryd/src/serve.rs` prints 433; the `diff` of the moved `reindex` (the deleted one in `serve.rs` vs the `pub(super) fn` in `admin.rs`, `pub(super)` normalised) prints nothing; `git diff --stat` lists only `serve.rs` and `git status --short` shows `serve/` and `serve_admin.rs` as new. `make gate` printed `gate: ok` with 1448 tests (1447 in `cargo test --workspace`, plus the 1 ignored `end_to_end`; the +4 over the 1444 before is exactly the tests of `serve_admin.rs`). No new dependency, so `Cargo.lock` unchanged. | ornith-1.5-35b-a3b |
