Then `edit.rs`: `noted` (checked text, a Noted note labelled by the session's taint and untrusted flag, appended to notes.md, answer "noted" or "noted (untrusted)"), `consolidate` (walk the lines, each old matched by `position` and each place named once or "twice", Keep/rename to after, Move/Drop to notes, New checked, a missing name reported), `edited` (add/replace/remove/consolidate with the duplicate, stale and not-an-identity-edit refusals, the Note arm returning an error the comment says `apply` never reaches), and `apply` (check, take the file, route an untrusted Add to `noted` with SAVED_AS_NOTE and every other untrusted action to `untrusted_refusal`, then before/after via `edited`, the duplicate check, the limit, write then append the moved notes). Added `pub mod edit;` after `pub mod config;` and `pub mod notes;` after `pub mod files;` in `lib.rs`. `cargo fmt --all`; `notes` 3 and `edit` 8 passed on the third run; `make gate` printed `gate: ok` — the first run failed on rustfmt import order, the second on clippy `manual_contains` (fixed by `before.contains(&text)`). No new dependency, so `Cargo.lock` is unchanged. | ? |

Filled the seven functions the skeleton left as `todo!()`: `grouped` (walk the digits' chars with their index, before each char where i > 0 and `(len - i)` is a multiple of 3 push a comma), `init` (recursive `DirBuilder` at 0700 then `set_permissions` to 0700, then `soul.md` from the starter when missing, then each of memory/user/notes empty when missing, nothing existing changed), `create` (`create_new` at 0600 so an existing file errors and is never overwritten), `entries` (read through `fail`, then `entries::parse`), `write_entries` (remove any stale temp, `create` the rendered list at 0600, then rename over the file), `append` (append+create at 0600, one write), and `block` (soul read and trimmed, over SOUL_LIMIT errors, the two identity files each: over limit errors, entries checked with `check` and the refused ones pushed onto `left_out`, the size counting the whole file). `cargo fmt --all`; `files` 8 passed; `make gate` printed `gate: ok` on the second run — the first failed on clippy `useless_format`, fixed by using `.to_string()` for the empty-soul line.

Added `pub mod check;` before `pub mod config;` and `pub mod entries;` after it in `lib.rs`, so the modules now list `check`, `config`, `entries`, `socket`. Filled the four functions of `entries.rs`: `parse` (walk `text.lines()`, a line whose trim() equals SEPARATOR ends an entry through `push` then clears `current`, any other line is pushed onto `current`, and `push` runs once more after the last line), `push` (join the lines with "\n", trim(), push as a String only when non-empty), `render` ("" for an empty list, otherwise the entries joined by "\n§\n" with a trailing newline), and `size` (render without its final newline, counted in chars via `chars().count()`).

Added `"crates/memoryd",` to the workspace `members` after `"crates/gatewayd",` and `rusqlite = { version = "0.40.2", features = ["bundled"] }` to `[workspace.dependencies]`. Added `Zlib` to the `deny.toml` allow list (for `foldhash`, a `rusqlite` dependency) and the `rusqlite` row to `docs/dependencies.md`. Appended the `memoryd-start-failed` runbook entry. Filled `Config::load` (`read_to_string` -> `ConfigError::Read`, `Config::parse` -> `ConfigError::Parse`, then a relative `soul_starter` resolved next to the config file via `path.parent().unwrap_or_else(|| Path::new("."))`); `Config::socket` (an empty `set` means `self.paths.home.join(default)`, otherwise the path as given); and `listen` (the same five steps as brokerd's `serve.rs::listen` — directory at 0700, symlink_metadata refusal, `set_permissions`, stale socket removed, bind then 0600 — with every error a `String` via `format!("{}: {e}", path.display())`). `cargo fmt --all`; the first `cargo build -p memoryd` compiled SQLite from source; `cargo deny check` reported the four "ok"s; `config` 4 passed and `socket` 2 passed; `make gate` prints `gate: ok` on the first run. | ? |
