Step 2 showed exactly the seven named failures (`refusals_change_nothing` in `edit`, `an_entry_that_fails_the_check_is_left_out_and_logged` in `serve`, all five in `serve_sanitize`); `files` did not compile (one E0609, no field `rule` on `&memoryd::check::Refused`) and `sanitize` did not compile (13: E0432 for `memoryd::edit::flagged`/`refused`, E0609 for `flag` on `Outcome` and `&Record` and `rule` on `Refused`, E0615 for `sentence`). Appended the three runbook fragments to `docs/runbook.md`; `check-runbook.sh` printed nothing and exited 0. `git rm`'d `crates/memoryd/src/check.rs` and its test. Made the edits in order: E1 removed `pub mod check;` from `lib.rs`; E2-E10 in `edit.rs` (imports, `Outcome` gains `flag`, five functions replacing `checked`, the refuse check in `apply`, the flag check after `edited`, `flag: None`, `text.trim()` in `edited`, `noted` plus `as_notes`, `text.trim()` in `consolidate`); E11-E13 in `files.rs` (imports, `Block`, the two `block` comments, the `refuse` match); E14-E19 in `journal.rs` (`Record` gains `flag` after `untrusted`, `record` sets `flag: outcome.flag.map(str::to_string)`, `log` appends ` flagged {rule}`, `undo` sets `flag: None`); E20 in `review.rs` (`reject` sets `flag: None`); E21-E23 in `serve.rs` (`block` logs by `refusal.rule` with the runbook pointer, the `memory` comment, and `memory` calls `edit::refused` first then `edit::flagged` to keep flagged writes off review and logs the rule). `cargo fmt --all`; `cargo check -p memoryd` clean; `cargo test -p memoryd` every suite passes (sanitize 11, serve_sanitize 5, edit 8, files 8, serve 8); `make gate` printed `gate: ok` with 1033 tests; `grep -rn 'memoryd::check\|crate::check' crates/` prints nothing. No new dependency, so `Cargo.lock` is unchanged. | ornith-1.5-35b-a3b | | M5b/05-sanitize-flag | 2026-09-26 | done | 1 | pass | none | Copied the three given tests from `docs/plans/M5b/files/`: `bxcore/tests/sanitize_flag.rs`, `sanitize_flag_corpus.rs`, `sanitize_flag_edges.rs`. Step 2 showed exactly the named E0432s (`Flag`/`flag`/`normalise` for `sanitize_flag`, `flag` for the other two). Copied the two skeletons, `bxcore/src/sanitize/normalise.rs` (five functions) and `flag.rs` (seven), then made the two edits: E1 replaced `bxcore/src/sanitize/mod.rs` whole (added `mod flag; mod normalise;` and `pub use flag::{Flag, flag};` / `pub use normalise::normalise;`), E2 made `invisible` `pub(super)` in `refuse.rs` (nothing else changed). Filled `normalise.rs` in the given order, each from its comment and `cargo check` after: `leet` (`LEET.iter().find` the digit, `map_or(c, |&(_, letter)| letter)`); `homoglyph` (`HOMOGLYPHS.iter().find` the `from`, `map` the `to`); `full_width` (`u32::from(c)` inside `FULL_WIDTH`, `checked_sub(FULL_WIDTH_OFFSET).and_then(char::from_u32).unwrap_or(c)`); `push_folded` (`full_width` then `homoglyph`, pushing the letter when `Some`, else `c.to_lowercase().map(leet)`); `normalise` (walk chars, `space` bool: whitespace sets it, `invisible` dropped leaving it, any other char pushes one `' '` when `space` and the output is not empty, clears `space`, then `push_folded`). Filled `flag.rs` in the given order: `in_sentence` (`!word.ends_with(['.','!','?',';']) && !["&&","||","|"].contains(&word)`); `filler` (`!word.is_empty() && word.chars().all(|c| c.is_alphanumeric() || c == '_')`); `is` (trim non-word ends with `trim_matches`, compare the word and its stripped form to each keyword); `ends_clause` (`word.ends_with(CLAUSE_ENDS)`, or `after.is_empty()`, or `after` starts with a `CLAUSE_FOLLOWERS` matched word by word as `is`); `one_word` (`split_first`, `test` the first word with the words after it, then `seq_at` the remaining parts on those words); `skip` (counts `0..=max`, `split_at_checked`: a skipped word failing `test` or a count past the end returns `false`, otherwise when all pass check `seq_at`); `seq_at` (`split_first`; `Is`/`Ends`/`Holds` go to `one_word` with `is`, `is && ends_clause`, `contains`, `Filler`/`Gap` to `skip` with `filler`/`in_sentence`). My first `one_word` edit dropped a `]` and `)` from the `impl Fn` signature; caught by diffing against the skeleton and fixed. After the fills `cargo check -p bxcore` is clean. `sanitize_flag` 22 passed, `sanitize_flag_corpus` 2, `sanitize_flag_edges` 2; `sanitize_refuse` 14, `sanitize_refuse_corpus` 2, `sanitize_tags` 15, `sanitize_corpus` 3. `cargo fmt --all`; `make gate` printed `gate: ok`; `cargo test --workspace` reports 1022 passed, plus the gate's separate loopd `end_to_end` ignored test, for 1023 total. No new dependency, so `Cargo.lock` is unchanged. | ornith-1.5-35b-a3b | | M5b/04-sanitize-refuse | 2026-09-26 | done | 1 | pass | none | Copied the given files from `docs/plans/M5b/files/`: the skeleton `bxcore/src/sanitize/refuse.rs` and the tests `bxcore/tests/sanitize_refuse.rs`, `bxcore/tests/sanitize_refuse_corpus.rs`, `bxcore/tests/support/keys.rs`. `bxcore/src/sanitize/mod.rs`: replaced the whole file (E1), adding `mod refuse;` and `pub use refuse::{Refusal, refuse};`. `bxcore/src/sanitize/tags.rs`: `next_tag` became `pub(super)` (E2), nothing else changed. Filled the eight functions in `refuse.rs` in the given order, each from its comment: `control` (`c.is_control() && c != '\n' && c != '\t'`), `first_char` (`char_indices().find` the first char the rule accepts, `map` to its byte offset), `private_use` (`u32::from(c)` inside one inclusive `PRIVATE_USE` range, as `invisible` does for `DEFAULT_IGNORABLE`), `noncharacter` (`0xFDD0..=0xFDEF` or `code & 0xFFFE == 0xFFFE`), `listed_tag` (`next_tag(text)` mapped to `before.len()`), `starts_word` (`!before.chars().next_back().is_some_and(|c| c.is_ascii_alphanumeric() || c == '_' || c == '-')`), `key_run` (`take_while` the run, counting chars and noting an upper and a digit, length in range and, if `mixed`, both seen), `private_key` (`match_indices("-----BEGIN")`, the line before trims empty and the BEGIN line trim_end()s onto one of `PRIVATE_KEY_ENDS`). Step 2 showed the three named E0432; step 3 compiled with the unfilled-function dead-code warnings. `key_run` failed once on `RangeInclusive` precedence: `secret.min..=secret.max.contains(&count)` parsed as a range, fixed by `(secret.min..=secret.max).contains(&count)`. After the edits `cargo check -p bxcore` is clean; `sanitize_refuse` 14 passed, `sanitize_refuse_corpus` 2 passed, `sanitize_tags` 15, `sanitize_corpus` 3. `cargo fmt --all`; `make gate` printed `gate: ok`; `cargo test --workspace` reports 996 passed, plus the gate's separate loopd `end_to_end` ignored test, for 997 total. No new dependency, so `Cargo.lock` is unchanged. | ornith-1.5-35b-a3b |
