From b4d631e249227369a4a480d8102fcf0618682850 Mon Sep 17 00:00:00 2001 From: Kyle Isom Date: Sat, 26 Sep 2026 21:22:40 -0700 Subject: [PATCH] loopd: neutralise user messages, tool results and the memory block Text from outside the model (the user's message, every tool result, and the memory block) is neutralised the moment it is first logged, so every later request replays the same bytes and a tag in that text cannot reach the model as one of its own control tokens. The model's own output, replay, and the system prompt are left byte-for-byte.

Re-ran `make gate`: `gate: ok` with 1042 tests. No new dependency, so `Cargo.lock` is unchanged. | ornith-1.5-35b-a3b | | M5b/06-memoryd-sanitize | 2026-09-26 | done | 1 | pass | none | Copied the five given tests from `docs/plans/M5b/files/`: `sanitize.rs`, `serve_sanitize.rs`, and new versions of `edit.rs`, `files.rs` and `serve.rs` (did not open them). 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 |
