Never switch branch. +**Commit subject:** `memoryd: Honcho's results as recall items, kept, labelled and interleaved` +**Log row:** the Task cell is `M5c2/06-memoryd-honcho-recalled`. + +## Goal + +From task 07 on, `recall` searches other agents' Honcho workspaces and the fleet's beside the +local index (M5c spec, section 8). This task writes the pure part: what `recall` makes of +Honcho's results. A new module, `crates/memoryd/src/honcho/recalled.rs`, turns one source's +results into items, interleaves the sources' items after the local hits, and labels the answer. +It does no I/O; nothing calls it until task 07. + +- **The inputs, per source**: its `Label` (task 05); the messages Honcho's workspace search + returned (`roncho::Message`); and for another agent's workspace, the conclusions of two + queries, about that agent's peer and then about the owner's (`roncho::Conclusion`). The fleet + has no conclusions: both lists are empty. +- **Relevance.** Honcho's search has no relevance cutoff: a query that matches nothing still gets + the nearest messages (recorded from rift, fixture 31). So a result is kept only when it shares + a whole word with the query (spec 8, amended), as the local index's full-text match requires. + Words are runs of alphanumeric characters (`char::is_alphanumeric`), lowercased; `tea` does + not match `steam` or `teatime`. +- **Duplicates.** Within one source, a result whose cleaned text equals an earlier kept one's is + dropped. Fixture 30 holds the same message twice. +- **Each item**: a header in the local format, `[n] {tag} · {from} · {class}`, then its text. + - `tag` is the source's (`memory` when the owner trusts it, else `memory-tainted`), `class` its + class, written as the local index writes one (`index::class_name`). + - `from` is `{name}: {peer} said, {when}` for a message and `{name}: a conclusion about + {peer}, {when}` for a conclusion. `{name}` is the source's name (the agent's, or `fleet`), so + a fleet hit reads `fleet: boxmaker2 said, …`, naming the peer that wrote it. `{peer}` is the + message's `peer_id` or the conclusion's `observed_id`, and `{when}` its `created_at` as a + local hit shows a time (`2026-09-28 23:19 UTC`, `recall::when`). + - The text is `neutralise`d, every control character (line breaks among them) and Unicode line + or paragraph separator becomes a space, and it is cut to its first 600 characters + (`recall::SNIPPET`), as a local snippet is cut: no mark is added. + - The text goes on the line after the header, indented by two spaces. So every line that + starts with `[` is a real header: a text shaped like a header (`[1] memory · …`, or a line + break and then one) can never begin a line (tip T37). Local items keep their own format. +- **Order within a source**: messages, then the conclusions about the agent's peer, then those + about the owner's, each in Honcho's order. +- **Interleaving to `k`.** The local index's hits come first, as today. Honcho's items fill what + is left of `k`: each source's first, in `recall_sources()` order, then each source's second, + and so on. **If the local hits alone fill `k`, no Honcho item is shown**: this is the spec's + "local index first". Honcho's items are numbered after the local ones. +- **The label** of the answer's Honcho part: the highest class of the items shown, `private` at + the least, and untrusted when any shown item is. An item dropped as irrelevant, as a duplicate, + or because `k` was full labels nothing (T58). +- **`{name}: unavailable`**: one line per source that did not answer, after the items. Task 07 + decides which did not. + +## Every place that changes + +This is the complete list. + +| Place | What happens there | +|---|---| +| `crates/memoryd/src/honcho/recalled.rs` | new: a skeleton you copy, then fill 3 bodies | +| `crates/memoryd/src/honcho/mod.rs` | `pub mod recalled;` (edit H1) | +| `crates/memoryd/src/recall.rs` | `when` becomes `pub(crate)`, for `recalled.rs` (edit R1) | +| `crates/memoryd/tests/honcho_recalled.rs` | new, given | +| everything else | **no change**: not `serve.rs`, not `recall`'s own function, no `Cargo.toml` | + +## Files + +- Copy, from `docs/plans/M5c2/files/` (the same path under it): the new test + `crates/memoryd/tests/honcho_recalled.rs`, and the skeleton + `crates/memoryd/src/honcho/recalled.rs`. +- Modify: `crates/memoryd/src/honcho/mod.rs`, `crates/memoryd/src/recall.rs`, + `docs/implementer-log.md`. +- Do not touch: any other file, and in the skeleton anything but its three `todo!()` bodies. + +## Facts you need + +- **The skeleton** is written except three bodies: `items`, `interleave` and `label`.
