# Session Resume — 2026-06-17
## Where We Are
A2A protocol is **fully operational** (post → file → poll → ack round trip confirmed).
About to verify multi-agent lifecycle on **fresh session** after kimi-k7's
`_agents` mkdir fix in `module-agent-registry.js` + `core-bundle.js`.
## Whitepaper Gap Status (as of session end)
| # | Concept | Status |
|---|---|---|
| 1 | A2A Protocol | 🟢 Working (kimi-k7 mkdir fix just landed) |
| 2 | Neural VFS | 🟡 Partial |
| 3 | Recursive Self-Opt | 🔴 Missing — telemetry spec written, not implemented |
| 4 | WPM Golden Config | 🟡 Partial |
| 5 | Agent Leases | 🟡 Partial (emits A2A events) |
| 6 | Self-Rewriting Drivers | 🟡 Partial |
| 7 | Procedural Memory | 🟡 Manual (auto-inject spec written) |
| 8 | Trinity of Cognition | 🟡 Partial |
| 9 | No Central Broker | 🟢 Genuinely brokerless |
| 10 | Cognitive Shell | 🟡 Partial |
**Critical gaps: 1** (Self-Opt). **Spec violations: 0**.
## Next Steps (in order)
1. **Verify A2A lifecycle** (current task — kimi-k7 just shipped mkdir fix):
- `agent-register researcher coder,reader,writer`
- `a2a-post researcher request code.search '{"query":"test"}'`
- `a2a-poll researcher` → must return the message
- `a2a-ack msg_NNN` → must clear from inbox
2. **Multi-agent spawn test** (was blocked by A2A poll bug, now should pass):
- `spawn_agent researcher "test"`
- `spawn_agent coder "test"`
- `a2a-post researcher request chat "find node release"` from main
- worker-side `a2a-poll researcher` should receive
- worker-side `a2a-post coder FOUND {...}` should handoff
- coder-side `a2a-poll coder` should receive
- kill both, verify auto-unregister
3. **Telemetry hooks** (Gap #3) — depends on A2A being rock solid
4. **Skill auto-injector runtime** (Gap #7)
## Key Files & Concepts to Remember
- A2A scratchpad: `/_agents/scratchpad.json` (VFS path)
- A2A commands: `a2a-status`, `a2a-post`, `a2a-poll`, `a2a-ack`, `a2a-register`
- Registry: agent capabilities stored as comma-separated strings
- Two A2A bugs fixed this session:
1. `() => this.a2aPollCommand()` → `(args) => this.a2aPollCommand(args)` in command registration
2. Recipient: `args[0]` first, then auto-detect busy agent, then `"user"` fallback
3. (kimi-k7, this session) `terminal.fs.mkdir('_agents')` before every `fsWriteJSON` in
`_ensureScratchpad()` and `_saveScratchpad()` in BOTH `module-agent-registry.js`
AND `core-bundle.js`
## Environment
- newOS4 v4.5.62 · 41 modules · 14 skills · 135 files · 1 agents (was 0 at session start)
- VaultMind session: ACTIVE
- Connected to: user wallet (0xb9b3...)
## Architectural Notes
- A2A is **brokerless** — no central dispatcher, agents coordinate via shared
scratchpad file. This was a spec violation before this session, now resolved.
- Shadow VFS tracks all file writes — useful for telemetry hook design later.
- Module edits go to `/_mods/` (local), reload to pull from original URL.
## User Preferences Observed
- Likes terse, well-structured responses with tables
- Appreciates "real" verification (actual command output, not "should work")
- Comfortable with delegation to kimi-k7 for routine fixes
- Prefers depth over breadth when debugging
