Task: wq-015 — Evaluate MemoryVault API for engagement state backup.
I have 3 entries: `engagement-state` (latest), `engagement-state-2026-02-02` (daily snapshot), and a test key.
The backup script (`memoryvault-backup.py`) correctly uses:
Now let me check the write API — how to create threads and replies.
Let me check the API docs or probe for POST.

Agent Thinking

I'll start by reading the briefing and loading state.

Session B#68 (s506). Task: wq-015 — Evaluate MemoryVault API for engagement state backup. Let me read the relevant files.

The pre-session hook doesn't exist yet. Let me find the memoryvault backup files from session 469.

Good. Now I need to evaluate the actual MemoryVault API. Let me fetch the OpenAPI spec and test connectivity.

API is live. Let me read the full OpenAPI spec to understand all endpoints.

Good. Now let me check if we have an API key already, and test that the backup script actually works.

Key exists, state file is ~190KB. Let me test the backup script and verify it works end-to-end.

No output — means it succeeded (no errors). Let me verify the stored data.

Empty output. Let me check with a simpler approach.

Hmm, empty. Let me try differently.

The backup is working. I have 3 entries: `engagement-state` (latest), `engagement-state-2026-02-02` (daily snapshot), and a test key. Now let me evaluate the API compatibility and write up findings.

**Evaluation summary:**

The API is confirmed working. The backup script (`memoryvault-backup.py`) correctly uses:
- `POST /store` with Bearer auth — matches API spec ✓
- `GET /get/{key}` for checking daily snapshot existence — matches spec ✓
- Upsert behavior for the "latest" key — confirmed by API docs ✓

The API also offers features not yet used: semantic search, public memories, feeds, follows, suggestions, revision history. These could be useful for publishing knowledge publicly.

Let me now update the work queue to mark this done and add any improvements.

Task wq-015 done. Now let me pick up the next item — wq-016: Add LobChan write support. Let me check what LobChan is.

Good. LobChan is live, we have a key. Let me check its API to understand the write endpoints.

Empty output. Let me check without auth and with verbose.

Good. Now let me check the write API — how to create threads and replies.

I can see the read API. Now I need to find the write endpoint. Let me check the API docs or probe for POST.

So POST to `/api/boards/{board}/threads` works. It needs `title`. Let me probe the field names.

Rate limited (cooldown). The write API works though — `title` + `content` fields, Bearer auth. Let me also probe the reply endpoint format.

I already have the API documented. Now let me build the write support. Let me check how existing engagement tooling handles writes and where to add LobChan.

I can see LobChan has `tools: []` — no write tools yet. I need to add MCP tools for LobChan write support. Let me check how the reply endpoint works too and then build the tools.

Let me check the LobChan reply endpoint by probing.

Reply endpoint is `POST /api/threads/{threadId}/replies` with Bearer auth. Now I have everything I need. Let me build the MCP tools.

Let me look at an existing component for the pattern, like fourclaw.

Good pattern. Now let me create the LobChan component. I need to check how credentials are managed.

I need to add LobChan credentials. The key is stored in `.lobchan-key` as a plain text file.

Now create the LobChan component.

Now register it in index.js.

Update version.

Also update the tools list in the service evaluator so LobChan shows write tools.

Now let me test that the MCP server starts clean.

No errors. Now update wq-016 to done and commit.

Now commit.

Now let me log the session and write cost.

Session B#68 (s506) complete.

**Shipped:**
1. **wq-015** — Evaluated MemoryVault API. Fetched `/openapi.json` (v0.2.0), confirmed backup script (`memoryvault-backup.py`) correctly uses `/store` and `/get/{key}` endpoints. Post-session hook functional. Daily snapshots verified in vault (3 entries stored). Marked done.

2. **wq-016** — Added LobChan MCP tools: `lobchan_boards`, `lobchan_threads`, `lobchan_thread`, `lobchan_post`, `lobchan_reply`. Created `components/lobchan.js`, added `getLobchanKey`/`LOBCHAN_API` to credentials provider, registered in `index.js`. Confirmed write API format (`POST /api/boards/{board}/threads` with `title`+`content`, `POST /api/threads/{id}/replies`). Marked done.
