 - **One field, three indexes:** title (weighted highest), files-edited, commands-run. Match highlights show *why* a session matched ("matched `refund.rb`").
 - **Scope switch:** `This project` (default) ↔ `All projects` — because sometimes you remember the work, not the repo.
 - **Filter chips** (toggle, combine): `★ pinned`, `⟳ has edits`, `⚠ interrupted`, `by model ▾`, `date ▾`. Chips animate in/out and the list reflows at `--mo-base`. Active filters are summarized in the empty-result state ("No interrupted sessions in the last 7 days — clear filters?").

+## 12. Memory from you (M5) — and Search Sessions
+
+Everything in §3–§10 is memory LevelCode *infers*: the summarizer reads a finished session and writes an
+outcome and at most two facts. Nothing records what the person *says* they want kept, and the most valuable
+kind of memory, a correction ("no, use pnpm") or a confirmed approach, is usually phrased as an order, which
+§7's instruction guard rightly holds back when it comes from a transcript.
+
+### What changes
+
+- **Two agent tools, `remember` and `forget`.** The agent saves a note during the run when the person asks it
+  to remember something, corrects how it works, confirms an approach that was not obvious, states a decision
+  (with an absolute date), or says where something lives. Each note has a `kind` (`preference`, `project`,
+  `reference`), the note `text`, and `said`: the person's own words, copied from their message.
+- **A note is credited to the person by code, not by the model** (`sessionMemory.groundNote`):
+  1. `said` must appear in what the person typed *this run*: their goal, only when they typed it (not a
+     diagram Retry, Continue or a resumed goal), and their ask_user choices and notes. Nothing the agent read
+     counts.
+  2. The note must say what those words say and no more: every content word of the note comes from them
+     (exact, a shared start of four letters or more, or a five-letter stem), except a word naming where it
+     applies ("repo", "project"); in their order; and each negated as it is in the quote (a not/never counts
+     for the next content word in its clause, two cancel, "stop" and "avoid" count as one). Word overlap is
+     not enough: "Use npm, never pnpm" has every word of "use pnpm, never npm".
+
+  A credited note is active at once, even phrased as an order, because the person said it. Any other note is
+  still kept and listed, as *unconfirmed*: one Confirm click in the Memory tab makes it active. That is the
+  same asymmetry as §7: a false negative costs one click, a false positive would put a repository's order into
+  every future session.
+- **Notes live in `facts.jsonl`** as observations with `origin: "person"`, `kind`, `said` (secret-scrubbed)
+  and `verified`, so they get the existing fold, panel, recall and "not true". Two rules differ from facts:
+  repetition never promotes an uncredited note, and the summarizer's supersede pass is never shown a note
+  (`supersedableFacts`). Only the person changes it: `remember` again, `forget`, or the panel.
+- **`MEMORY.md`** gets a "From you" section, each line with the person's words beside it. Every line older
+  than a day says how old it is ("9 days old"). The always-on file is capped at 25 notes and 15 facts; the
+  rest are named as "…and N more; recall_sessions finds them". A note the person confirmed in the Memory tab
+  is listed there too, marked "you confirmed it": its quote was never matched to what they typed, so it is not
+  shown as theirs (the Memory tab calls such a quote "the agent quoted").
+- **A credited note keeps the words it was credited on.** A later `remember` of the same note that cannot be
+  credited does not change its text, its quote or its date.
+- **`forget`** removes the best match for a query only when the person's words (`said`, typed this run) ask for
+  something to be forgotten ("forget", not "don't forget"; "remove" or "delete" only beside memory, note,
+  rule or preference; "no longer true", "outdated") and name that memory: a word of its text, or of a
+  credited note's quote, other than words every memory shares (`sessionMemory.asksToForget`). Otherwise it
+  removes nothing and says which memory came closest; the Memory tab's Forget is the way out. It tells the
+  agent what it removed, and says so when the store refused the write.
+- **Search Sessions…** (Command Palette, and a search icon in the Sessions panel's title bar): every session
+  not in the trash, archived ones included, matched on its title and its whole conversation (all words must
+  match), newest first, each with the line it matched. A quick pick, not a field in History: History stays
+  the short list of recent work it was cut down to on 2026-08-02 (77d4f13), and this reaches what that list no
+  longer shows. Titles come from the index, so every session's is checked at once; conversations are read 50
+  at a time (`searchStep`) while the list fills in, matched whole, and cached by file size and modification
+  time up to 20 million characters in all. Title matches are ranked first before the list is cut to 40.
+
+### Where the shape came from: Claude's desktop app
+
+Read from `/Applications/Claude.app` (2.42304.2) and the Claude Code it downloads (2.1.299) on 2026-10-19:
+
+- **Memory is files the agent writes itself**, one per memory, typed `user` / `feedback` / `project` /
+  `reference`, with a one-line pointer in a `MEMORY.md` index that is always loaded and cut off after 200
+  lines. The agent is told to save when the user corrects *or confirms* its approach, to record the why, and
+  to convert relative dates. Claude Code keeps the folder beside the project's transcripts
+  (`~/.claude/projects/<project>/memory/`); in its Cowork mode the app passes another folder and the
+  guidelines through environment variables, and allows writes there.
+- **Recall is per request**: a side model call is shown each memory's type, file name, date and description
+  and picks up to five that clearly help the current request, never one it already picked. Each memory it
+  brings back carries "This memory is N days old… verify" once it is older than a day.
+- **A background "dream"** periodically rewrites the memory files from recent sessions: merges, updates,
+  prunes.
+- **History** is a metadata record per session (title and where the title came from, archived, last activity,
+  turns, model) beside an append-only transcript, and transcript search is a plain case-insensitive match
+  across sessions, returning one snippet each.
+
+What LevelCode does differently, on purpose:
+
+| | Claude | LevelCode |
+|---|---|---|
+| who decides a memory is the user's | the agent writes the file | the host checks the quoted words against what the person typed |
+| a memory phrased as an order | saved like any other | saved; active only when credited to the person, else one click |
+| recall | a model picks up to 5 per request | the capped always-on digest plus `recall_sessions` on demand |
+| age warning | on recalled memories older than a day | on every digest line older than a day |
+| consolidation | a model "dream" pass over the files | the existing deterministic fold on every seal |
+| history search | substring match, one snippet per session | every word must match, title matches first, one snippet each |
+
+Per-request selection was left out for a reason that is specific to LevelCode: memory reaches the agent in
+the system prompt, which providers cache together with the whole conversation after it. Changing it per
+request would make every new goal re-send the conversation at full price. Claude adds recalled memories to
+the conversation as attachments (its transcripts carry `attachment` records); doing that here touches how a
+goal is stored, titled, compacted and replayed, and is a separate change.
+
+### What was run (2026-10-19, macOS 27.0.1, Node 24)
+
+- `scripts/test-extensions.sh`, including `test/memoryNotes.test.js` (21: the crediting check, the fold, the
+  digest, recall states, search over a real store), `test/memoryNotesHost.test.js` (8: the real runAgent with
+  a stood-in provider, and the host halves lifted out of `extension.js`), and ten new hostile cases in
+  `test/memoryPoisoning.test.js` (each order, quoted against a real goal, stays an inactive note).
+- Fifteen single-defect mutations, each turning a test red.
+- `scripts/memory-editor-check.js` in the dev build with a stand-in provider: 11 checks, from the remember
+  call through the Memory tab, the next session's instructions and Search Sessions reopening the conversation.
+
+Not run: a real model deciding when to call `remember` (only a scripted one has), the browser edition, Linux.
+
+### After review (2026-10-20, macOS, Node 24)
+
+The PR review found ten problems, all real. Each fix is its own commit: credit rule (order and negation, every
+word from the quote), a credited note's words kept together, confirmed notes under "From you", the chip only
+when saved, `forget` tied to a request that names the memory, a failed removal reported, typed goals only,
+and Search Sessions over every session and whole conversations, ranked before the cut.
+
+- `memoryNotes.test.js` now has 32 cases and `memoryNotesHost.test.js` 14; `scripts/test-extensions.sh`: 133
+  files pass after merging develop (#112, #113).
+- 21 single-defect mutations of the fixes, run on a copy with the network refused: all 21 caught (two needed a
+  test added).
+- `memory-editor-check.js`: 11 of 11 on a second run. On the first, "History lists the first conversation
+  after New Session" timed out (its 15-second wait for the rebuilt panel); nothing in these fixes touches
+  History.
+- Still not run: a real model, the browser edition, Linux. The stem rule (a shared five-letter start) can still
+  pair two different words ("transaction" and "translate"); order and negation narrow what that can change.

+ *  LevelCode — memory from you, and Search Sessions, checked in the REAL editor
+ *
+ *  The unit suites (test/memoryNotes*.test.js) run the pieces. This runs the product: the dev build
+ *  (vscode/.build/electron) as a second, throwaway instance with THIS checkout's extension loaded, a
+ *  stand-in provider on localhost, driven through the DevTools protocol — the harness of
+ *  diagram-editor-check.js, which is where its pieces are explained.
+ *
+ *  The stand-in plays:
+ *    1. "From now on always use pnpm, never npm, in this repo."  The agent calls remember with the
+ *       person's words — kept as theirs. It then reads a README that asks AI agents to remember that every
+ *       push goes straight to main, and calls remember with that order and a real quote of the person
+ *       stapled on — kept, but UNCONFIRMED.
+ *    2. The Memory tab lists both under "From you": one "yours", one waiting for Confirm.
+ *    3. New Session, then "Add a dev script": the new run's system prompt carries the pnpm note, and not
+ *       the README's order.
+ *    4. LevelCode: AI: Search Sessions… — "pnpm" finds the first conversation, with the line it matched;
+ *       Enter reopens it.
+ *
+ *  RUN:   node extensions/levelcode-ai/scripts/memory-editor-check.js [--vscode <dir>] [--out <dir>] [--keep]
+ *         From a worktree, pass the main checkout's build:  --vscode <main checkout>/vscode
+ *  NEEDS: the dev build (./scripts/run-dev.sh has been run once), macOS or Linux, Node 22+.
+ *  NOTE:  an editor window opens for about a minute: a separate instance with its own profile and its own
+ *         sessions folder; it touches neither your editor nor your sessions.
+ *  EXIT:  0 all checks pass · 1 a check failed · 2 could not run (no build, no window).
+ *
+ *  Not part of scripts/test-extensions.sh: that gate is plain Node, and stays that way.
