+**Commit subject:** `memoryd: recall's local items on one indented line, as Honcho's`
+**Log row:** the Task cell is `M5c2/07-memoryd-recall-form`.
+
+## Goal
+
+Task 06 gave Honcho's `recall` items one form: a header, then the text on one line indented by
+two spaces, with every line break made a space. So a text shaped like a header (`[2] identity ·
+…`) can never begin a line of the answer, where the model would read it as a real item (tip T37).
+The local index's items still keep a hit's line breaks, and put its text at the start of the
+line after the header. A page fetched in a session is not indexed, but what the owner and the
+assistant said about it is, and a note can hold anything: a forged header there begins a line
+today.
+
+This task gives local items the same form, with one pair of functions that both kinds of item
+use (M5c spec, section 8):
+
+- **`recall::snippet(text)`**: `neutralise`d, every control character and Unicode line or
+  paragraph separator a space, cut to its first 600 characters (`SNIPPET`) with no mark. Local
+  hits were cut the same way before, without the other two steps; the local index holds text
+  `loopd` has neutralised already, so neutralising again changes nothing there.
+- **`recall::item(header, text)`**: the header, a line break, two spaces and the text.
+- `recalled.rs` (task 06) keeps `clean` and `Item::render`, but they now call these two, so there
+  is one copy of the rule.
+
+And for task 08, which puts Honcho's items after the local ones:
+
+- **`recall::local(...)`**: what `recall` does, up to the items: the search, the recall log,
+  then `Local { items, class, untrusted }`, the rendered items numbered from 1 and their label
+  (`private` and trusted when there are none).
+- **`recall::recall(...)`** answers from `local`, as before: the items joined by line breaks, or
+  `(no matches for "…")` when there are none. Only the items' form changes.
+
+Nothing else reads `recall`'s answer as text: `loopd` passes it to the model, and `bxctl`,
+`gatewayd` and the device tests do not parse it (checked). Two assertions of `memoryd`'s own
+`recall` test pinned the old form; the test gets a new version.
+
+## Every place that changes
+
+This is the complete list.
+
+| Place | What happens there |
+|---|---|
+| `crates/memoryd/src/recall.rs` | `snippet`, `item`, `Local`, `local`; `recall` answers from `local` (edits R1 to R5) |
+| `crates/memoryd/src/honcho/recalled.rs` | `clean` and `Item::render` call `snippet` and `item`; two `use` lines (edits H1 to H4) |

+| `crates/memoryd/tests/recall.rs` | new version, given: two assertions follow the new form |
+| everything else | **no change**: not `serve.rs`, not `index.rs`, no other test, no `Cargo.toml` |
+
+## Files
+
+- Copy, from `docs/plans/M5c2/files/` (the same path under it): the new test
+  `crates/memoryd/tests/recall_form.rs`, and a **new version** of
+  `crates/memoryd/tests/recall.rs` (it replaces the file in the tree).
+- Modify: `crates/memoryd/src/recall.rs`, `crates/memoryd/src/honcho/recalled.rs`,
+  `docs/implementer-log.md`.
+- Do not touch: any other file. `docs/plans/M5a/files/` keeps its own older copy of `recall.rs`;
+  do not copy from there.
+
+## Facts you need
+
+- **`recall.rs` today**: `recall(index, store, args, session, now) -> Result<Recalled, String>`
+  checks the arguments, searches, logs the recall, then either answers `(no matches for "…")` or
+  builds one item per hit (`format!("{}\n{text}", hit.header(i + 1))`, the text cut to `SNIPPET`
+  characters) and joins them. Edits R3 to R5 split it: the body up to the items becomes `local`,
+  and `recall` calls `local` and joins. The search, the log line and the headers do not change.
+- **`recalled.rs` today** (task 06): `clean` holds the same rule as the new `snippet`, and
+  `Item::render` the same layout as the new `item`. Edits H3 and H4 make them call the new
+  functions; `neutralise` and `SNIPPET` are then no longer used there, so edits H1 and H2 change
+  its `use` lines.
+- **`neutralise`** (`bxcore::sanitize::neutralise(&str) -> Cow<str>`) writes each chat-template
+  tag's angle brackets as `&lt;` and `&gt;`; text with none is returned as it is.
+- **The given tests.**
+  - `recall_form.rs` (4 tests): `snippet` and `item`, and that `recalled::clean` gives what
+    `snippet` does; three forged headers in indexed text (after a line break, at the start, after
+    a CRLF), each kept inside its own item, with only real headers beginning a line; a tainted
+    hit (said after an untrusted tool result) forging a trusted `memory` header, shown under its
+    own `memory-tainted` header, the answer untrusted; `local`'s items and label, `recall`'s
+    answer made from them, and the `(no matches …)` answer as before.
+  - `recall.rs`: two assertions change, `hits_are_tagged_and_labelled` (the text follows `\n` and
+    two spaces) and `long_hits_are_cut` (the body is what follows `\n` and two spaces).
+- The items the edits use. This table is complete.
+
+  | Item | Where |
+  |---|---|
+  | `bxcore::sanitize::neutralise` | R2 (moved from `recalled.rs`) |
+  | `char::is_control`, `Iterator::map`, `Iterator::take`, `Iterator::collect` | R2 (moved from `recalled.rs`) |

+## Steps
+
+- [ ] **1. Copy the given tests.** From the repository root, two commands:
+
+  ```sh
+  cp docs/plans/M5c2/files/crates/memoryd/tests/recall_form.rs crates/memoryd/tests/
+  cp docs/plans/M5c2/files/crates/memoryd/tests/recall.rs crates/memoryd/tests/
+  ```
+
+  Then `git status --short` lists `crates/memoryd/tests/recall.rs` as modified and
+  `recall_form.rs` as new.
+- [ ] **2. See them fail.** Two commands, each with a shell timeout of 600000 ms:
+  - `cargo build --tests --keep-going -p memoryd`: one test target, `recall_form`, does not
+    compile: `E0432`, ``unresolved imports `memoryd::recall::Local`, `memoryd::recall::item`,
+    `memoryd::recall::local`, `memoryd::recall::snippet` ``. Every other target compiles.
+  - `cargo test --no-fail-fast -p memoryd --test recall`: two tests fail,
+    `hits_are_tagged_and_labelled` and `long_hits_are_cut`.
+- [ ] **3. The edits.** Make edits R1 to R5 and H1 to H4, in order. `cargo check -p memoryd`
+  prints no error and no warning.
+- [ ] **4. The tests.** With a shell timeout of 600000 ms, every test passes: 4 in
+  `recall_form`, 6 in `recall`, 11 in `honcho_recalled`, and 2 in `forgery`, as before:
+
+  ```sh
+  cargo test -p memoryd --test recall_form --test recall --test honcho_recalled --test forgery
+  ```
+- [ ] **5. Check.** `git diff --stat -- crates/memoryd/src` lists exactly
+  `crates/memoryd/src/honcho/recalled.rs` and `crates/memoryd/src/recall.rs`.
+- [ ] **6. Run the gate.** `cargo fmt --all`, then `make gate`, with a shell timeout of 600000 ms.
+  Expected last line: `gate: ok`. The test count is the passed total of `cargo test --workspace`
+  plus one, for the ignored `end_to_end` test that the gate runs on its own: **1418** after this
+  task, 1414 before it; the 4 new ones are the tests of `recall_form.rs`. To count, add up the
+  `N passed` of every `test result:` line the gate's `cargo test --workspace` printed, and add
+  1. Never run the gate again only to count.
+- [ ] **7. Log and commit.** Add your row to `docs/implementer-log.md`; its Task cell is
+  `M5c2/07-memoryd-recall-form`. Stage with
+  `git add crates/memoryd docs/implementer-log.md Cargo.lock`, then commit as `AGENTS.md` says.
+  `Cargo.lock` does not change in this task; the `git add` is harmless.
+
+## Done when
+
+- `make gate` prints `gate: ok` with 1418 tests.
+- `git diff HEAD~1 --stat` lists only `recall.rs`, `recalled.rs`, `recall_form.rs`, the test
+  `recall.rs` and `docs/implementer-log.md`.
+
+## Stop and report if
+
+- The branch check at the top fails.
+- A "before" block is not in its file exactly as shown when its turn comes, or is there more
+  than once. H1 to H4 quote the parts of `recalled.rs` that task 06's skeleton gave, not the
+  bodies you filled.
+- Step 2 shows a different result: other targets failing, other errors, or other tests failing.
+- `cargo check` in step 3 prints an error or a warning. Quote it, and stop.
+- A test fails in step 4. Do not change a test: stop, and give the failing tests' names and
+  their messages.
+- The fix seems to need a change anywhere else: `serve.rs`, `index.rs`, another test, a copy
+  from `docs/plans/M5a/files/`. It does not; stop and say why you think so.
+- A test outside the given files fails in the gate: check once whether it fails without your
+  change (`git stash -u`, run it, `git stash pop`), then stop and report both results.
+- The gate passes with a count other than 1418.
+- A comment in an edit does not fit the code under it. Quote it and stop.
