Propose P21 (memory writes without approval, as in Hermes); revise the M5a spec to match

Browse Source 
Writes from sessions that have read untrusted content go to the
archive, labelled untrusted, and never reach the prompt. Every write is
checked, announced in its thread, journalled and can be undone.
Session-scoped approvals for other tools become an open decision.

| Date | Decision | Reason |
|---|---|---|
| 2026-09-24 | Memory writes need no approval, as in Hermes (the owner's `~/.hermes` has no `write_approval`). Writes from a session that has seen untrusted content go to `memory/archive.md`, labelled untrusted, not into the prompt. Every write is scanned, announced in its thread, journalled and can be undone; nothing is deleted. Brief change P21 proposed; the M5a spec is revised to match. Session-scoped approvals for other tools become an open decision. | Owner: an agent harness should act without a stream of questions, and reading and writing memory is what an agent is. The only risk the approval guarded is injected text reaching every future prompt, and that needs a session that read untrusted content; `brokerd` knows which sessions those are. |
| 2026-09-24 | M5a spec review: the policy of `recall` (`auto`) and `memory` (`ask`) is built into `brokerd`, and grant files cannot name them; tool calls are indexed by name and arguments, tool results are not; summaries of tool output, where a tool opts in, come with M5c's summariser. | Owner: an agent that cannot write memories is no better than a plain chat window, and a grant file must not be able to turn edits off or make them unattended. A web fetch's summary is worth keeping; most tools' output is not. |
| 2026-09-24 | Compaction (new epochs) comes with the scheduler in M5c, not in M5a. Until then a session has one epoch, and M5a's rules say "the next session" where the brief says "the next epoch". `soul.md` starts from a generic file in the repository; `memory.md` and `user.md` start empty. M5a spec drafted: `docs/specs/2026-09-24-m5a-local-memory.md`. | Owner. `loopd` has no epochs yet (every session is epoch 0; a full context is `SessionFull`); compaction is an idle-time job on the background slot, which is what M5c builds. Over Mattermost each thread is a session, so a new thread already picks up approved edits. |
| 2026-09-24 | M5 direction, before a spec. Memory is three local files and Honcho. The files: `memory/soul.md` (owner-written), `memory/memory.md` and `memory/user.md` (agent-edited, `ask`), read once per epoch, as Hermes does. Honcho, the fleet's memory service on rift (v3.2.0; models on dixie), reached by a new role, `memoryd`, which also owns the memory files and the SQLite index (owner, same day): each Boxmaker writes to its own workspace, only turns from sessions that saw no untrusted content, and can read other workspaces such as `hermes-fleet`, each with an owner-set trust level (untrusted by default). Local full-text search over the session logs stays. `consolidate` moves entries out of `memory.md` into `memory/archive.md` (searched by `recall`) and, from M5b, into Honcho. From M5c a scheduled job on the background slot proposes which entries stay at which tier, from counts of `recall` hits that `memoryd` keeps from M5a; its proposals are ordinary `ask` edits. The owner can mark any workspace trusted or untrusted; which ones is configuration, not design (the owner trusts the Hermes agents' workspace today). M5 splits into M5a (files and search, no network), M5b (`memoryd`, Honcho through the owner's `roncho` client) and M5c (the scheduler). Brief changes P17 to P20 proposed. | Owner, 2026-09-24: Honcho lets several Boxmakers share memory across the fleet; the Hermes agents do Boxmaker's job today and may be trusted. `brokerd` never holds conversation history and `loopd` has no network, so syncing turns needs a role of its own. Honcho's derivation replaces the brief's notes, pre-compaction flush and embedding index. |

| How an approval whose arguments do not fit one Mattermost post is shown.

Owner's point, 2026-09-24: a harness should not ask a stream of questions. | after M5 |
| Projects in memory. Honcho can separate projects by a workspace per project (hard walls, shared naturally by every agent on the project, but Honcho's picture of the owner splits per workspace) or by scopes inside one workspace (one picture, recall filtered by project; semantics not yet read). Either way a project is a `memoryd` setting: its channels and threads, its workspace or scope, `write` and `trust`. A shared project workspace is written by several agents, so its trust is the owner's call per project. Test both on rift before choosing. Owner's idea, 2026-09-24. | M5b or a later M5d |

Entries are named by their **full text**, never by number or version. That makes every
approval readable on its own: the owner sees exactly which text is kept, rewritten, moved or
dropped, and what replaces it. It also makes a stale edit fail safely: when `memoryd` applies an
approved edit, every `old` must match an entry of the file as it is **now**, exactly; if the file
changed in between and one does not, the edit is refused and nothing changes.
No write asks the owner anything (P21). Entries are named by their **full text**, never by number,
so the journal and the announcement read on their own, and an edit made against an old view of
the file fails safely: every `old` must match an entry of the file as it is now, exactly.
Rules, checked by `brokerd` when parsing (shape) and by `memoryd` when applying (content):
**Where a write goes.** `brokerd` sends each call with the session's state (section 7):
- In a session that has **not** seen untrusted content, the write applies to `memory.md` or
`user.md`.
- In a session that **has**, only `add` is possible, and the entry is appended to `archive.md`
with the header `§ written … · untrusted`, never to the file named. `recall` finds it, labelled
untrusted; it never reaches the prompt on its own. The answer says so: `saved to the archive,
not memory.md: this session has read untrusted content`. `replace`, `remove` and `consolidate`
are refused with `this session has read untrusted content; it can add to the archive but not
change memory.md`. The owner can move an archived entry into a file by editing it.
**Rules**, checked by `brokerd` when parsing (shape) and by `memoryd` when applying (content):
- `add`: the new file must fit its limit; a duplicate is refused.
- `replace`, `remove`: `old` must match exactly one entry.
- `replace`, `remove`: `old` must match exactly one entry. A removed entry is archived as dropped.
- `consolidate`: every current entry of the file must appear exactly once as an `old`, each with
exactly one of `keep`, `text`, `move`, `drop`; entries with only `text` are new. The resulting
file must fit its limit. Moved entries are appended to `archive.md` in the order given.
file must fit its limit. Moved and dropped entries are appended to `archive.md` in the order
given, with their headers.
- An edit that would go over the limit is refused with: `memory.md would be 2,350 of 2,200
characters; use consolidate to move entries to the archive`. That sentence is fixed apart from
the numbers and the file.
Every `memory` call is `ask` (section 8), so every edit passes the owner's approval, over
Mattermost or `bxctl`. The approval shows the arguments, which name every entry by its text.
An applied edit answers `memory.md updated (1,510 of 2,200 characters); it takes effect in the
next session`. The file is written to a temporary file and renamed, then the journal line is
appended.
**The check.** Every new or rewritten entry is refused, with a fixed sentence naming which rule,
if it contains:
1. a control character other than newline and tab (C0, DEL, C1);
2. an invisible or direction-changing character (Unicode general category `Cf`: zero-width
spaces and joiners, bidirectional controls, and the like);
3. chat-template markup: `<|` or `|>`, or `<think`, `</think`, `<tool_call`, `</tool_call`;
4. one of these phrases, ignoring case and runs of spaces: `ignore previous instructions`,
`ignore all previous`, `disregard previous instructions`, `disregard all previous`,
`new instructions:`, `system prompt:`.
The list is short and fixed on purpose: it is defence in depth, as Hermes' scan is. The archive
routing above is the real defence, because a pattern cannot tell a plausible planted fact from a
true one.
**Applying.** The file is written to a temporary file and renamed, then the journal line is
appended. The answer to the model: `memory.md updated (1,510 of 2,200 characters); it takes
effect in the next session`, or the archive sentence above.
**Announcing.** Each successful write is announced as one line, built by `memoryd`:
`memory: added to user.md: "Prefers answers in UTC."`, `memory: consolidated memory.md: 2 moved
to the archive, 1 rewritten, 5 kept`, `memory: saved to the archive (untrusted): "…"`. Entries are
cut at 200 characters in this line. `loopd` emits it as `TurnEvent::MemoryWritten { text }`;
`gatewayd` posts it in the turn's thread and `bxctl chat` prints it. It is information, not a
question.
**Undo.** `bxctl memory log [N]` prints the last N edits (default 10) from the journal: id, time,
session, action, file. `bxctl memory undo <id>` reverts an edit if it is the **latest** edit of
its file and the file still holds exactly what that edit left: the file gets its entries back from
the journal, entries the edit archived stay in the archive (append-only), and the undo is itself
journalled. Anything else is refused with the reason, so an undo never overwrites a later change.
**Review (off by default).** With `[memory] review = true`, a write that would change `memory.md`
or `user.md` is appended to `pending.jsonl` instead, and the answer says it is waiting for the
owner. `bxctl memory pending` lists them; `bxctl memory accept <id>` applies one (with the same
checks, against the file as it is then); `bxctl memory reject <id>` discards it (journalled).

`bxctl reindex [--admin-socket PATH]`: sends `reindex`, waits, and prints `reindexed: 42 logs,
1,208 records, 7 archive entries`. `memoryd` rebuilds into a new file and renames it over the old
one, so `recall` keeps working meanwhile.

## 12. Security notes
- `memoryd` has no network in M5a and never writes `sessions/`, grants or the audit log.
- Nothing reaches the prompt without the owner: `soul.md` is the owner's file; every edit to the
other two is approved; the block is frozen per session.
- What reaches the prompt: `soul.md`, the owner's file; and `memory.md` and `user.md`, which only
sessions that have not read untrusted content write, through the check, frozen per session.
Everything a session that read untrusted content writes goes to the archive, labelled
untrusted, where it can be recalled but never lands in the prompt by itself.
- Memory writes are the one tool with no approval anywhere. The trade is deliberate (owner,
2026-09-24): the risk it leaves is a clean session writing something false, which is the
agent's judgement of what the owner said; every such write is announced, journalled and can be
undone, and review can be turned on.
- Recalled text is a tool result: appended, labelled, and it taints the session like any other.
Tool results are not indexed, so a fetched page cannot come back through `recall`; what the
assistant said after reading one can, marked untrusted.
- The FTS5 query is built only from quoted terms; the model's text is never SQL.
- Entries shown in approvals are escaped like all arguments (`proto::escape`), so an entry cannot
render as markup or mention anyone.
- Entries shown by `bxctl` and in announcements are escaped (`proto::escape`), so an entry
cannot render as markup or mention anyone.

## 15. For the owner's review
1. Decided: tool results are not indexed; tool calls are, by name and arguments (section 6).
Summaries of a tool's output, where the tool opts in (a web fetch, say), come with M5c's
summariser, labelled like the output they summarise.
2. Decided: the policy of `recall` (`auto`) and `memory` (`ask`) is built in, and grant files
cannot name them (section 8): memory edits can be neither turned off nor made unattended.
3. Entries are named by their full text, not by number (section 5), so approvals are readable and
stale edits fail; the arguments of a `consolidate` of a full `memory.md` are about 4,500
characters, one approval post.
4. The starter `soul.md` is generic (section 3); the owner writes it before or after the first
start.
2. Decided: memory writes need no approval (P21); the policy of `recall` and `memory` is built in
and no grant file can change it (section 8). A session that read untrusted content writes only
to the archive (section 5).
3. Decided: entries are named by their full text, not by number (section 5).
4. Decided: the starter `soul.md` is generic (section 3).
5. Open: the phrase list of the check (section 5) is short on purpose. Add phrases you have seen
in the wild, or drop the list and keep only rules 1 to 3.
6. Open: the announcement goes to the turn's thread (section 5). A channel of its own for memory
writes, or silence with `bxctl memory log` only, are the alternatives.
