This task +**decides** each journalled edit into the ledger (task 07); the worker sends them in task 13. +With `[honcho]` only: without it nothing changes. + +- **When.** Right after `journal::record` (the memory tool, and a reviewed write when the owner + accepts it) and after `journal::undo` (`bxctl memory undo`), in the same call, under the index + lock those calls already hold. So edits are decided in the journal's order. +- **Items.** `Item::Edit { id: , part }`, one part per Honcho action, numbered + from 0 in the order they must be sent. The outbox's order is then the send order. +- **The mapping** (spec section 4's table, as journal records show it): + + | The journal record | The actions, in order | + |---|---| + | an identity edit (`file` is `memory.md` or `user.md`): add, replace, remove, consolidate, and an undo | each entry dropped: `Unconclude`; then each entry added: `Conclude` about the owner (`user.md`) or the agent (`memory.md`) | + | entries `consolidate` moved to notes (`§ moved` notes of the record) | nothing: not counted as dropped | + | a write saved as notes (`file` is none) with a flag rule (`flag` set) | one `Skip { why: "flagged: " }` | + | the same, untrusted (`untrusted`), not flagged | each `noted` note: `Fleet` | + | the same, trusted, not flagged | each `noted` note: `Conclude` about the agent | + | anything else (a rejection) | nothing | + + "Dropped" and "added" are the multiset difference of the entries before and after, by text: a + replace is one of each (part 0 the `Unconclude` of the old, part 1 the `Conclude` of the new), + a reorder is none, and one of two equal entries removed is one dropped. An undo's `before` is + the file as it was, its `after` what the undo restored, so the same difference is its inverse: + the conclusions its edit made are deleted, and any it deleted are made again. +- **The session.** A `Conclude` or `Fleet` carries the Boxmaker session id of the write, as + task 07's schema has it (which Honcho session that is sent into is task 13's). The owner's undo + is journalled with the session `owner`: its conclusions carry the undone edit's session instead, + following `undoes` back (through an undo of an undo). With no session at all, a part that needs + one is a `Skip { why: "the edit has no Boxmaker session" }`; a deletion needs none. +- **Text.** Kept as journalled; the worker neutralises it when it sends (task 13). +- **Nothing to send:** an edit whose mapping is empty gets no line. A flagged write gets its + `Skip` line, so that `bxctl memory sync` (task 14) can show that it stayed local. +- **Retractions.** An undo never touches a note (notes are append-only: `journal::undo` refuses + them), so nothing here ever decides `Action::Retract`; it stays in the ledger's schema unused. + +**The locks.** A walk (task 09) holds `TurnSync`'s lock while it asks `brokerd`, up to 5 s. A +memory write must not wait for that: it is the model's tool call. So this task gives the ledger a +lock of its own, held only to read or append (edits T1 to T8): the walk takes it briefly for each +check and append, the worker for each read and append, and a memory write for its appends. The +order is always index → ledger, or walk → ledger, and the ledger's lock is never held while +another is taken. A given test holds a walk on a silent `brokerd` and makes a memory call. + +## Interfaces + +In `crates/memoryd/src/honcho/mirror.rs` (the module `memoryd::honcho::mirror`): + +```rust +pub const OWNER: &str = "owner"; +pub const NO_SESSION: &str = "the edit has no Boxmaker session"; +pub fn diff(before: &[String], after: &[String]) -> (Vec, Vec); // (dropped, added) +pub fn session_of(record: &journal::Record, records: &[journal::Record]) -> Option; +pub fn actions(record: &journal::Record, session: Option<&SessionId>, agent: &str, owner: &str) + -> Vec; +pub struct Mirror { /* private */ } +impl Mirror { + pub fn new(ledger: Arc>, agent: &str, owner: &str) -> Mirror; + pub fn journalled(&self, store: &Store, id: Option<&str>, now: Timestamp, log: &dyn Fn(&str)); +} +``` + +`TurnSync` (task 09): its ledger is an `Arc>`; `ledger()` returns the locked +ledger (a `MutexGuard`, which the existing calls use as before), and `shared_ledger()` the lock +itself. `worker::Opened` gains `mirror()`, and `Memoryd` a `mirror: Option` and a +private `mirror(&self, id)`. + +## Every place that changes + +This is the complete list. + +| Place | What happens there | +|---|---| +| `crates/memoryd/src/honcho/mod.rs` | `pub mod mirror;` (edit H1) | +| `crates/memoryd/src/honcho/mirror.rs` | new: a skeleton you copy, then fill 7 bodies | +| `crates/memoryd/src/honcho/turns.rs` | the ledger's own lock (edits T1 to T8) | +| `crates/memoryd/src/honcho/worker.rs` | the worker reads and appends under the ledger's lock; `Opened::mirror` (edits W1 to W9) | +| `crates/memoryd/src/serve.rs` | `Memoryd.mirror`, and the two calls (edits S1 to S7) | +| everything else (`journal.rs`, `edit.rs`, `review.rs`, `ledger.rs`, tests of earlier tasks) | **no change** | + +## Files + +- Copy, from `docs/plans/M5c1/files/` (the same path under it): the new tests + `crates/memoryd/tests/honcho_mirror.rs` and `crates/memoryd/tests/honcho_mirror_serve.rs`, and + the skeleton `crates/memoryd/src/honcho/mirror.rs`. +- Modify: the files of edits H1 to S7, `docs/implementer-log.md`. +- Do not touch: any other source file, any other test or support file, any `Cargo.toml`, and in + the skeleton anything but the 7 `todo!()` bodies. + +## Facts you need + +- **A journal record** (`memoryd::journal::Record`, M5a): `id`, `session`, `action`, `file` (the + identity file's name, or `None` when the write was saved as notes), `before` and `after` (the + file's entries), `notes` (each note appended, rendered: a header line and its text), `untrusted`, + `flag` (the flag rule a write matched), `undoes` (for an undo, the edit it reverted).
