M5a implementation plan: local memory

For the implementing model: do not work from this file. The owner gives you one task file at a time (01-… to 15-…). This file is the index for the owner and the reviewer.

Goal: a new role, memoryd, owns the agent's memory: identity (soul.md, memory.md, user.md, in every new session's prompt) and experience (notes.md and the session logs, found with recall). The agent writes memory with a memory tool without asking; a session that has read untrusted content can only take notes. brokerd decides both tools under built-in grants and hands them to memoryd; loopd takes the memory block from memoryd for each new session.

Architecture: brokerd's two largest files are split first (01). proto gains the tools' arguments and eight message kinds (02). memoryd is built bottom up: its crate, configuration and sockets (03), entries and the check (04), the files and the block (05), notes and the edits (06), the journal, undo and review (07), the index (08), recall (09), and serving (10). brokerd gains the two tools and their built-in grants (11), then sends decided memory calls to memoryd with the session's state, keeping the stricter label (12). loopd takes the block and declares the two core tools (13); bxctl gains reindex and memory (14). Last, the starter soul.md and the device checks with memoryd running (15).

Spec: docs/specs/2026-09-24-m5a-local-memory.md (approved; P17 to P21 applied to the brief). Runbook: task 03 adds memoryd-start-failed, task 12 memoryd-unreachable, task 13 replaces core-memory-unreadable with memory-unavailable and adds memory-index-damaged.

New dependency: rusqlite 0.40.2 with bundled (task 03; deny.toml gains Zlib for foldhash). Nothing else.

Global constraints

• Everything in AGENTS.md, including "Lessons from earlier reviews".
• Branch m5a. One task, one fresh OpenCode session, one commit. Run cargo fmt --all before the gate. Review happens once, after task 15.
• New files come as skeletons: types, constants and the glue written, todo!() bodies with the code to write in the comment above. Existing files are changed by the exact edits in the task, never replaced whole.
• Some tasks hand over new versions of given test files, because the change is in what the test must see. Copy them over the old ones as the task says; they are still not to be edited.
• Only task 15 needs straylight (make verify-device). Everything else runs offline against temporary directories and fakes.

Tasks

Every task had a reference implementation, built in this order from master with the gate at every step and replayed on its own (tip T26), its given tests run against it, and mutations of it caught by them (tip T28); then the reference was moved off this machine (tip T18). Every skeleton was checked to compile at its task's end state and to fail its tests, and every comment above a todo!() was read beside its signature (tip T29). The three largest functions were split before the skeletons were cut (tip T25).

At the end of task 15: 936 tests (854 before task 01). Each task's count was checked by running the gate at its end state on its own.
