Exactly — swapping the raw IP for a **semantic addressing scheme** like
|
||
|
||
```
|
||
bzzz://agent:role@project:task/path/to/context
|
||
```
|
||
|
||
makes a *lot* more sense in a P2P + SLURP/BZZZ world.
|
||
Here’s why:
|
||
|
||
---
|
||
|
||
## **Why Semantic > IP Address**
|
||
|
||
1. **Location-independent** — you don’t care *where* the agent physically is, only *what it is* and *what it’s doing*.
|
||
2. **Self-describing** — anyone reading the URI can immediately infer:
|
||
|
||
* **Agent** → identity (human, bot, service)
|
||
* **Role** → function or responsibility
|
||
* **Project** → higher-level grouping
|
||
* **Task** → sub-scope within project
|
||
* **Path** → hierarchical context location (HCFS path)
|
||
3. **Resilient to churn** — if a node changes IP, it can still announce under the same project/task space.
|
||
4. **Supports dynamic discovery** — peers subscribe to project/task channels, so they automatically learn new agents or context without knowing network topology.
|
||
|
||
---
|
||
|
||
## **How This Works in a P2P Mesh**
|
||
|
||
* **Announce**:
|
||
|
||
```
|
||
bzzz announce bzzz://alice:frontend@chorus:ui-redesign/src/components/navbar
|
||
```
|
||
|
||
→ Published over the BZZZ gossip layer.
|
||
|
||
* **Lookup**:
|
||
Any peer can query:
|
||
|
||
```
|
||
bzzz get bzzz://any:frontend@chorus:ui-redesign/src/components
|
||
```
|
||
|
||
The mesh routes to the *closest* peer with that context (by latency or chunk availability).
|
||
|
||
* **Routing layer**:
|
||
Under the hood, `project:task` maps to a *swarm namespace* (think topic in a pub/sub system).
|
||
The actual transport (IP, QUIC, etc.) is abstracted away — only the routing fabric knows it.
|
||
|
||
---
|
||
|
||
## **Bonus Benefits**
|
||
|
||
* **Easier onboarding** — no need to teach new nodes about IP addresses or ports; they just announce with semantic URIs.
|
||
* **Cross-project federation** — the same agent could appear in multiple project\:task spaces without changing network plumbing.
|
||
* **Natural fit for role-based SLURP filtering** — your role & project are literally in the address, so the curator knows instantly what context you can see.
|
||
|
||
---
|
||
|
||
If you like, I can **sketch a lightweight `bzzz://` URI grammar & resolution spec** that defines:
|
||
|
||
* Allowed characters & formats for `agent`, `role`, `project`, `task`.
|
||
* How the mesh resolves them to actual peers.
|
||
* How caching & replication work.
|
||
* How this plugs into SLURP’s permission and event system.
|
||
|
||
That would make it concrete enough for you to start building BZZZ announce/lookup commands without locking into IP-based thinking.
|
||
|
||
|
||
|
||
Nice—this is exactly the right direction. Treating `bzzz://` URIs as **semantic resource addresses** and supporting REST-like verbs (GET/POST/PUT/DELETE) mapped onto the P2P mesh and your HCFS/SLURP stack gives you a clean, powerful, and auditable control surface.
|
||
|
||
Below I’ll give you a focused, implementable **protocol spec**: URI grammar, verb semantics, payload shapes for event-driven POSTs, example flows, security rules, idempotency/versioning, and how SLURP/HCFS should process these messages (and log them to the hyperlog / `context_events` table). You can iterate from this into code, CLI commands, or a lightweight RFC for your team.

# bzzz:// Protocol — Practical Spec (draft)
|
||
|
||
## 1 — URI grammar (informal)
|
||
|
||
```
|
||
bzzz://[agent]:[role]@[project]:[task]/[path...][?query][#fragment]
|
||
```
|
||
|
||
* `agent` — identifier for the emitter (human, service, bot). \[a–zA–Z0–9\_.-]
|
||
* `role` — semantic role (frontend, devops, finance, curator). \[a–zA–Z0–9\_-]
|
||
* `project` — project namespace. \[a–zA–Z0–9\_-]
|
||
* `task` — task or subproject identifier. \[a–zA–Z0–9\_-]
|
||
* `/path/to/context` — HCFS-style hierarchical path; components may include `/` separators.
|
||
* `?query` — optional parameters (e.g., `depth=2&version=7`)
|
||
* `#fragment` — optional fragment inside blob
|
||
|
||
**Example**
|
||
|
||
```
|
||
bzzz://alice:frontend@chorus:website-redesign/src/modules/db/connection
|
||
```
|
||
|
||
---
|
||
|
||
## 2 — Basic verbs & semantics
|
||
|
||
Map familiar REST verbs to P2P actions:
|
||
|
||
### `GET bzzz://...`
|
||
|
||
* **Intent:** Retrieve an assembled context packet for `role/channel/path` or to fetch a resource (blob, metadata).
|
||
* **Behavior:**
|
||
|
||
* SLURP checks permissions -> resolves path -> returns composed context (with metadata).
|
||
* May consult LightRAG and TGN for ranking/drift warnings if requested (`?use_lightrag=true`).
|
||
* **Response:** `200` with `{ context, metadata, source_blob_ids, drift_score, events_considered }`
|
||
* **Cacheable:** yes (subject to freshness flags)
|
||
|
||
### `POST bzzz://...` (create / event submit)
|
||
|
||
* **Intent:** Submit a new **event** or **context blob**. For events, payload carries `message-type` (event\_type) and semantics.
|
||
* **Behavior:**
|
||
|
||
* Receives payload (see event payload schema below).
|
||
* Validate sender (signature/ACL).
|
||
* Insert `context_events` and/or `context_blobs` in HCFS.
|
||
* Publish announcement on mesh pubsub for `project:task` swarm.
|
||
* SLURP curators listening see the event and may act (re-curation, revocation, quarantine).
|
||
* **Idempotency:** client should include `idempotency_key` (UUID) to avoid duplicates.
|
||
* **Response:** `201` with `event_id`, `hyperlog_ref`, and `applied=true|queued` depending on processing.
|
||
|
||
### `PUT bzzz://...` (update)
|
||
|
||
* **Intent:** Update an existing resource (e.g., revise an event or blob).
|
||
* **Behavior:** require `resource_id` or `version` in query; insert a new version or update mutable metadata. Log versioning.
|
||
* **Response:** `200` with new `version_id`, `hyperlog_ref`.
|
||
|
||
### `DELETE bzzz://...`
|
||
|
||
* **Intent:** Soft-delete or mark obsolete (rarely hard-delete — prefer soft deletes for audit).
|
||
* **Behavior:** mark `end_time` on event or set `deleted=true` in blob metadata; announce to mesh.
|
||
* **Response:** `200` with `deleted=true` and hyperlog ref.
|
||
|
||
### `SUBSCRIBE / UNSUBSCRIBE` (pubsub)
|
||
|
||
* Semantic action for live channels: `bzzz sub bzzz://...` subscribes to notifications/announcements on the project\:task namespace.
|
||
|
||

|
||
|
||
## 3 — Event POST payload (JSON)
|
||
|
||
This is the general structure for posting dynamic events (blockers, warnings, approvals, etc.):
|
||
|
||
```json
|
||
{
|
||
"idempotency_key": "uuid-v4",
|
||
"message_type": "blocker", // enum: announcement|warning|blocker|approval|priority_change|access_update|structural_change
|
||
"title": "Payment module under audit",
|
||
"content": "Do not deploy or change DB schemas until audit complete.",
|
||
"path": "/src/modules/payments",
|
||
"scope": { "project": "chorus", "task": "payments-launch" },
|
||
"severity": 9, // 1-10
|
||
"visibility": { "roles": ["frontend","backend"], "channels": ["dev"], "exclude": [] },
|
||
"start_time": "2025-08-10T10:00:00Z",
|
||
"end_time": null,
|
||
"created_by": "alice",
|
||
"signature": "base64(sig)", // optional but recommended
|
||
"metadata": { "ticket": "JIRA-1234", "owner": "pm_team" }
|
||
}
|
||
```
|
||
|
||
Notes:
|
||
|
||
* `message_type` maps to `event_type` in DB.
|
||
* `visibility` indicates role/channel scoping — SLURP uses this to decide who sees it.
|
||
* `signature` signed with agent private key over canonicalized JSON to ensure authenticity.
|
||
|

|
||
|
||
## 4 — Example flows
|
||
|
||
### A. Developer posts a blocker (your example)
|
||
|
||
**Command**
|
||
|
||
```
|
||
bzzz post bzzz://any:developer@chorus:website-redesign/db/connection/credentials \
|
||
'{"message_type":"blocker","title":"Hardcoded DB creds","content":"Remove credentials; rotate keys","path":"/src/modules/db/connection","visibility":{"roles":["devops","backend"]}}'
|
||
```
|
||
|
||
**Processing**
|
||
|
||
1. Node receives POST, validates `idempotency_key` and `signature`.
|
||
2. Writes event into `context_events` (DB) and creates a `graph_node` + `graph_edge` (event node, linked to path node).
|
||
3. Publishes `bzzz.announce` on pubsub for `chorus:website-redesign`.
|
||
4. SLURP instances subscribed to that project\:task see the event → decide action:
|
||
|
||
* If `severity >= 8` and `visibility` includes `devops`, SLURP may quarantine affected blob(s), notify WHOOSH to run remediation ansible playbook, and log a hyperlog decision.
|
||
5. Response includes `event_id`, `hyperlog_ref` and `applied:true`.
|
||
|
||
### B. Agent requests context and gets override
|
||
|
||
**Command**
|
||
|
||
```
|
||
bzzz get bzzz://bob:frontend@chorus:website-redesign/src/modules/db/connection?use_lightrag=true
|
||
```
|
||
|
||
**Processing**
|
||
|
||
1. SLURP inspects active events on `/src/modules/db/connection` and parent paths. Finds `blocker`.
|
||
2. Depending on project event\_type\_definitions, SLURP either:
|
||
|
||
* **suppress** normal blobs and return only blocker note, or
|
||
* **annotate** returned context with the blocker at top
|
||
3. If allowed, SLURP calls LightRAG to re-rank candidate blobs (restricted to those the requester may see).
|
||
4. SLURP returns composed payload and logs to hyperlog.
|
||
|
||
---
|
||
|
||
## 5 — Mapping to HCFS / SLURP / TGN storage
|
||
|
||
When a POST is accepted:
|
||
|
||
* Insert into `context_events`:
|
||
|
||
* `(path, event_type, content, severity, start_time, end_time, created_by, project_id)`
|
||
* Create `graph_nodes` entry for the event and `graph_edges` linking event→path and created\_by→agent.
|
||
* Append a hyperlog entry (hypercore) that records the event and SLURP's decision.
|
||
* Publish mesh announcement: `bzzz:announce` topic with minimal envelope:
|
||
|
||
```json
|
||
{ "type":"event_announce", "project":"chorus", "task":"website-redesign", "event_id": 123, "path": "/src/...", "message_type":"blocker" }
|
||
```
|
||
|
||
TGN ingestion: event becomes a temporal edge for the TGN model (src: agent node, dst: path or blob node, event\_type, timestamp).
|
||
|
||
---
|
||
|
||
## 6 — Security & Permissions
|
||
|
||
* **Authentication:** Agents hold keypairs. Use Ed25519 signatures. When posting, include `signature` and `public_key_id`. Validate against ACLs in `graph_nodes` or `agents` table.
|
||
* **Authorization:** SLURP enforces `visibility` and `role` constraints. If a posting agent tries to create an event affecting roles they don't control, SLURP may mark `status=pending` and route to human approver.
|
||
* **Encryption:** Use layer transport TLS/QUIC, and optionally encrypt payloads for specific roles using symmetric keys shared by the project’s team.
|
||
* **Auditability:** Never hard-delete events; always append an "end\_time" or tombstone entry. Hyperlog retains immutability.
|
||
|
||
---
|
||
|
||
## 7 — Idempotency, versioning & conflict handling
|
||
|
||
* **Idempotency key** (client-generated UUID) ensures repeated POST attempts don't create duplicates.
|
||
* **Versioning:** context blobs and events are immutable records with explicit versions. `PUT` creates a new version rather than in-place mutation (or marks prior version end\_time).
|
||
* **Conflict resolution:** for concurrent edits, use last-writer-wins by timestamp + signature OR a merge flow managed by SLURP/curator (create merge candidates, present to humans or meta-curator).
|
||
|
||
---
|
||
|
||
## 8 — PubSub & discovery model
|
||
|
||
* **Topic namespace:** `bzzz.project.<project>.task.<task>` (or `bzzz.project.chorus.task.website-redesign`)
|
||
* **Announcements:** All writes publish lightweight announcements so subscribed peers discover new events quickly without fetching full payload.
|
||
* **Pull model:** on announcement, peers decide whether to `GET` the full event or ignore.
|
||
* **Replication:** `bzzz` nodes will replicate blobs via content-addressing (hashes) and chunked streaming (libp2p style), storing locally per retention policy.

||
## 9 — Implementation notes / pseudocode
|
||
|
||
### POST handler pseudocode (simplified)
|
||
|
||
```python
|
||
def handle_post(uri, body, signature):
|
||
parsed = parse_bzzz_uri(uri)
|
||
assert validate_signature(body, signature, parsed.agent)
|
||
|
||
# 1. Validate message_type and visibility
|
||
if not allowed_to_post(parsed.agent, parsed.project, body['path'], body['message_type']):
|
||
return 403
|
||
|
||
# 2. Check idempotency
|
||
if exists_event_with_idempotency_key(body.get('idempotency_key')):
|
||
return existing_event
|
||
|
||
# 3. Insert into DB
|
||
event_id = insert_context_event(body, parsed)
|
||
|
||
# 4. Create graph node + edges
|
||
node_id = create_graph_node('event', ref_id=event_id)
|
||
create_graph_edge(agent_node(parsed.agent), node_id, 'created')
|
||
|
||
# 5. Append hyperlog entry (immutable)
|
||
hyperlog_ref = hyperlog.append({...})
|
||
|
||
# 6. Publish announcement
|
||
pubsub.publish(topic_for(parsed.project, parsed.task), { 'type': 'event_announce', 'event_id': event_id })
|
||
|
||
# 7. Return success
|
||
return { 'event_id': event_id, 'hyperlog_ref': hyperlog_ref }
|
||
```
|
||
|
||
### GET handler pseudocode (simplified)
|
||
|
||
```python
|
||
def handle_get(uri, params):
|
||
parsed = parse_bzzz_uri(uri)
|
||
# 1. AuthN & AuthZ - ensure agent role can read requested path
|
||
check_read_permission(parsed.agent, parsed.role, parsed.path)
|
||
|
||
# 2. Check context_events for overrides
|
||
events = find_active_events(parsed.path)
|
||
action = resolve_action_based_on_project_definitions(parsed.project, events, parsed.role)
|
||
if action == 'suppress':
|
||
return format_response_with_events_only(events)
|
||
|
||
# 3. Query HCFS for blobs matching path & role/channel
|
||
blobs = fetch_context_blobs(parsed.path, parsed.role, parsed.channel)
|
||
if params.use_lightrag and len(blobs) >= threshold:
|
||
lrag_res = lightrag.query(restrict_ids=[b.lightrag_doc_id for b in blobs])
|
||
chosen = lrag_res.chunks
|
||
else:
|
||
chosen = blobs
|
||
|
||
# 4. TGN check for drift
|
||
drift = tgn.get_drift_score(parsed.path)
|
||
|
||
# 5. Compose response, log decision
|
||
resp = compose_context_packet(chosen, events, drift)
|
||
hyperlog.append({ 'request':uri, 'decision':..., 'returned_ids': [...] })
|
||
return resp
|
||
```
|
||

|
||
|
||
## 10 — Operational / UX considerations
|
||
|
||
* **CLI tool**: `bzzz post ...`, `bzzz get ...`, `bzzz sub ...` — wraps canonical signing and pubsub convenience.
|
||
* **Human review queue**: if a POST creates a high-risk action (e.g., revoke access), route to dashboard for a human to approve.
|
||
* **Rate limits & throttles** on post events to avoid spam floods.
|
||
* **Retention policy** for replicated model blobs and context blobs (LRU or TTL per project).
|
||
|
||
---
|
||
|
||
## 11 — How SLURP & WHOOSH interact with this protocol
|
||
|
||
* **SLURP** subscribes to `bzzz` pubsub topics for the projects it curates. On announcements it:
|
||
|
||
* pulls event payload
|
||
* evaluates via project `event_type_definitions`
|
||
* takes actions (suppress, annotate, notify, route to WHOOSH)
|
||
* logs decisions to hyperlog
|
||
|
||
* **WHOOSH** (automation/orchestration) listens for high-severity `blocker` or `access_update` events:
|
||
|
||
* runs Ansible playbooks (install bzzz client, run `ollama pull` fallback, or trigger model replication).
|
||
* on success/failure, posts back a status event (POST `message_type: announcement` with metadata).
|
||
|
||

|
||
|
||
## 12 — Next concrete deliverables I can give you right away
|
||
|
||
Pick one and I’ll produce it:
|
||
|
||
* **A. Formal `bzzz://` URI BNF grammar + canonical JSON schema** for GET/POST/PUT/DELETE payloads (suitable for adding to a spec doc).
|
||
* **B. CLI design & sample implementation** (Python) with signing, pubsub announce, and hyperlog append.
|
||
* **C. Fast prototyping plan** using libp2p (py-libp2p or go-libp2p) + a tiny HTTP shim (so `bzzz` URIs are handled by a local daemon that maps to libp2p calls).
|
||
* **D. Event handling flow doc** showing how SLURP processes `POST` events end-to-end (with exact DB writes and hyperlog entries).
|
||
|
||
|
||
Nice — I’ll give you all four, structured and ready to drop into your docs or hand to an engineer. I’ll keep each section practical and implementation-ready: **A** (formal grammar + payload schemas), **B** (CLI spec + Python stub), **C** (fast prototype plan using libp2p + HTTP shim), **D** (end-to-end SLURP event handling flow with DB + hyperlog details).
|
||
|
||

|
||
|
||
## A — `bzzz://` URI Grammar (BNF) + JSON Schemas
|
||
|
||
### A.1 — BNF grammar (informal, precise)
|
||
|
||
```
|
||
<bzzz-uri> ::= "bzzz" "://" <agent> ":" <role> "@" <project> ":" <task> <path> [ "?" <query> ] [ "#" <fragment> ]
|
||
|
||
<agent> ::= <id> ; [A-Za-z0-9_.-]+
|
||
<role> ::= <id> ; [A-Za-z0-9_.-]+
|
||
<project> ::= <id> ; [A-Za-z0-9_.-]+
|
||
<task> ::= <id> ; [A-Za-z0-9_.-]+
|
||
<path> ::= "/" <segment> { "/" <segment> }
|
||
<segment> ::= [A-Za-z0-9_.-]+ ; allow dot, underscore, hyphen
|
||
<query> ::= <param> { "&" <param> }
|
||
<param> ::= <key> "=" <value>
|
||
<fragment> ::= <string>
|
||
|
||
Example:
|
||
bzzz://alice:frontend@chorus:website-redesign/src/modules/db/connection?use_lightrag=true#v3
|
||
```
|
||
|
||
**Notes:**
|
||
|
||
* All IDs normalized to lowercase for routing.
|
||
* Percent-encoding allowed for unusual characters in path segments.
|
||
* `agent` may be `any` for anonymous or service-level posts, but authenticity must be validated via `signature` in payload.
|

|
||
### A.2 — Canonical JSON Schemas
|
||
|
||
All schemas in OpenAPI-style JSON (trimmed to essentials). Use `message_type` as event\_type enum.
|
||
|
||
#### A.2.1 — `GET` Response (context packet)
|
||
|
||
```json
|
||
{
|
||
"type": "object",
|
||
"required": ["context", "metadata"],
|
||
"properties": {
|
||
"context": { "type": "string" },
|
||
"metadata": {
|
||
"type": "object",
|
||
"properties": {
|

"source_blob_ids": { "type": "array", "items": { "type": "integer" } },
|

"lightrag_doc_ids": { "type": "array", "items": { "type": "string" } },
|
||
"events_considered": { "type": "array", "items": { "type": "integer" } },
|
||
"drift_score": { "type": "number", "minimum": 0, "maximum": 1 },

}
|

}
|
||
```
|
||
|

|
||
|
||

|
||
{
|

"type":"object",
|

"required":["idempotency_key","resource_id","updates"],
|

}
|

}
|

```
|
||

||
|
||
## B — CLI Design & Python Sample Implementation (signing, pubsub announce, hyperlog append)
|
||
|
||
### B.1 — CLI UX surface (commands)
|
||
|
||
```
|
||
bzzz post <bzzz-uri> --file payload.json
|
||
bzzz get <bzzz-uri> [--use-lightrag]
|
||
bzzz put <bzzz-uri> --file update.json
|
||
bzzz delete <bzzz-uri> --file delete.json
|
||
bzzz sub <bzzz-uri> # subscribe to project:task announcements
|
||
bzzz announce <bzzz-uri> --meta '{...}' # low-level announce
|
||
```
|
||
|
||
* All commands auto-sign with local key (unless `--no-sign`).
|
||
* Default transport: local daemon via HTTP shim on `http://localhost:19000/` (see C).
|
||
* CLI handles idempotency keys (generates UUID if not provided) and prints returned `event_id` + `hyperlog_ref`.
|
||
|
||
---
|
||
|
||
### B.2 — Python CLI minimal stub (uses `requests` to local shim + Ed25519 signing)
|
||
|
||
Save as `bzzz_cli.py`. This is a minimal, production-adjacent example — adapt to your codebase.
|
||
|
||
```python
|
||
#!/usr/bin/env python3
|
||
import argparse, json, requests, os, sys, uuid
|
||
from nacl.signing import SigningKey
|
||
from nacl.encoding import Base64Encoder
|
||
from urllib.parse import urlparse
|
||
|
||
# Config
|
||
SHIM_URL = os.getenv("BZZZ_SHIM_URL", "http://localhost:19000")
|
||
|
||
# Load or create key
|
||
KEY_PATH = os.path.expanduser("~/.bzzz/signing.key")
|
||
if not os.path.exists(KEY_PATH):
|
||
os.makedirs(os.path.dirname(KEY_PATH), exist_ok=True)
|
||
sk = SigningKey.generate()
|
||
with open(KEY_PATH, "wb") as f:
|
||
f.write(sk.encode())
|
||
else:
|
||
sk = SigningKey(open(KEY_PATH,"rb").read())
|
||
|
||
pk_b64 = sk.verify_key.encode(encoder=Base64Encoder).decode()
|
||
|
||
def sign_payload(payload_bytes):
|
||
sig = sk.sign(payload_bytes).signature
|
||
return Base64Encoder.encode(sig).decode()
|
||
|
||
def post(uri, payload):
|
||
body = payload.copy()
|
||
if "idempotency_key" not in body:
|
||
body["idempotency_key"] = str(uuid.uuid4())
|
||
body_bytes = json.dumps(body, separators=(",", ":"), sort_keys=True).encode()
|
||
signature = sign_payload(body_bytes)
|
||
headers = {
|
||
"Content-Type": "application/json",
|
||
"X-BZZZ-Signature": signature,
|
||
"X-BZZZ-PubKey": pk_b64
|
||
}
|
||
resp = requests.post(f"{SHIM_URL}/post", params={"uri": uri}, data=body_bytes, headers=headers, timeout=10)
|
||
resp.raise_for_status()
|
||
return resp.json()
|
||
|
||
def get(uri, use_lightrag=False):
|
||
resp = requests.get(f"{SHIM_URL}/get", params={"uri": uri, "use_lightrag": str(use_lightrag).lower()}, timeout=10)
|
||
resp.raise_for_status()
|
||
return resp.json()
|
||
|
||
def main():
|
||
p = argparse.ArgumentParser()
|
||
sub = p.add_subparsers(dest="cmd")
|
||
p_post = sub.add_parser("post"); p_post.add_argument("uri"); p_post.add_argument("--file")
|
||
p_get = sub.add_parser("get"); p_get.add_argument("uri"); p_get.add_argument("--use-lightrag", action="store_true")
|
||
args = p.parse_args()
|
||
|
||
if args.cmd == "post":
|
||
if args.file:
|
||
payload = json.load(open(args.file))
|
||
else:
|
||
payload = {}
|
||
res = post(args.uri, payload)
|
||
print(json.dumps(res, indent=2))
|
||
elif args.cmd == "get":
|
||
res = get(args.uri, use_lightrag=args.use_lightrag)
|
||
print(json.dumps(res, indent=2))
|
||
else:
|
||
p.print_help()
|
||
sys.exit(1)
|
||
|
||
if __name__ == "__main__":
|
||
main()
|
||
```
|
||
|
||
**Notes:**
|
||
|
||
* Uses `pynacl` (`libsodium` binding) for Ed25519 signing.
|
||
* `SHIM_URL` talks to local daemon (C) which maps to real P2P calls and does hyperlog append.
|
||
|
||
---
|
||
|
||
### B.3 — Hyperlog append API (local shim expectations)
|
||
|
||
Local shim must expose endpoints:
|
||
|
||
```
|
||
POST /post?uri=<bzzz-uri> # same as bzzz post
|
||
GET /get?uri=<bzzz-uri>&use_lightrag=true
|
||
POST /announce # lightweight announcement
|
||
```
|
||
|
||
On incoming POST, shim will:
|
||
|
||
* verify signature using `X-BZZZ-PubKey`
|
||
* forward to cluster (local node or forward to appropriate peer)
|
||
* append event to hyperlog (local feed) and return `{"event_id":123, "hyperlog_ref":"feed:345"}`
|
||
|
||
---
|
||
|
||
## C — Fast prototype plan: libp2p + HTTP shim
|
||
|
||
Goal: ship a working prototype in days, not months. Use libp2p for P2P transport and a local HTTP daemon to map `bzzz://` calls to libp2p operations. Keep implementation minimal:
|
||
|
||
### C.1 — Components
|
||
|
||
* **Local daemon** (Go or Python) — exposes HTTP endpoints (`/post`, `/get`, `/announce`, `/sub`) and runs libp2p node.
|
||
* **libp2p peer** — provides pubsub, DHT, and direct stream capabilities.
|
||
* **Hyperlog** — use `hypercore` or a Mongo/SQLite append-only table (for prototype, use a local append-only SQLite table or simple file-based log). Hypercore JS is an option if you prefer Node.
|
||
* **Discovery** — mDNS for LAN + optional bootstrap peers for multi-network.
|
||
|
||
### C.2 — Minimal tech choices (fastest path)
|
||
|
||
* **Go**: `go-libp2p` + `go-http` — performant, production-friendly.
|
||
* **Python**: `py-libp2p` (less mature) or run a small `node` helper for libp2p. If you want speed, use Go for the shim.
|
||
* **DB**: SQLite for prototype (later Postgres).
|
||
* **LightRAG**: separate service (optional); initial prototype: skip LightRAG or stub it.
|
||
|
||
### C.3 — Minimal runtime flows
|
||
|
||
#### Startup
|
||
|
||
* Node boots libp2p, joins DHT, subscribes to `bzzz.project.<project>.task.<task>` topics configured in local file.
|
||
* Node exposes HTTP on `localhost:19000`.
|
||
|
||
#### POST
|
||
|
||
* HTTP shim receives POST -> validate signature -> write event into local hyperlog -> publish `event_announce` on topic -> attempt to store in HCFS DB or forward to known curator nodes.
|
||
|
||
#### GET
|
||
|
||
* Shim resolves request: check local HCFS DB -> if not present, query DHT for peers with `path` -> open libp2p stream to peer(s) and retrieve blob -> run SLURP logic (basic ACLs) -> return composed packet.
|
||
|
||
#### SUBSCRIBE
|
||
|
||
* Shim subscribes to pubsub topic and emits events on local websocket to CLI or UI.
|
||
|
||
### C.4 — Development tasks (order)
|
||
|
||
1. Implement HTTP shim skeleton with `/post` and `/get` routes.
|
||
2. Wire libp2p pubsub announce & subscribe.
|
||
3. Implement a simple hyperlog (append-only SQLite table) and hyperlog append/ read.
|
||
4. Implement signature verification (Ed25519).
|
||
5. Implement simple SLURP rules engine (role/channel/path ACL check + event override logic).
|
||
6. Hook in LightRAG later as a separate service (call via HTTP).
|
||
7. Add `bzzz` CLI that calls shim (B).
|
||
|
||
### C.5 — Security / dev ops notes
|
||
|
||
* For local network dev, mDNS + DHT is fine; for production, bootstrap peers + TLS + persistent peer lists.
|
||
* Run shim as systemd service and enable socket activation if desired.
|
||
|
||
---
|
||
|
||
## D — Event Handling Flow: SLURP processing `POST` events (end-to-end)
|
||
|
||
I’ll describe concrete DB writes, hyperlog entries, pubsub announce, curator actions, and WHOOSH triggers. Use this as the implementation recipe.
|
||
|
||
### D.1 — Inputs
|
||
|
||
* HTTP POST: `bzzz://alice:dev@chorus:website-redesign/src/modules/db/connection` with JSON `body` (see A.2.2), headers:
|
||
|
||
* `X-BZZZ-Signature`
|
||
* `X-BZZZ-PubKey`
|
||
|
||
### D.2 — Validation & initial checks
|
||
|
||
1. **Signature verification**: verify `body` canonical JSON signature against `X-BZZZ-PubKey`. If fail → 401.
|
||
2. **Idempotency**: check `idempotency_key` in `context_events` table. If exists → return existing event record (HTTP 200).
|
||
3. **Authorization**: check posting agent (`alice`) is permitted to post events in `project` context (`chorus`) — consult `agents` table or `graph_nodes` ACL. If not permitted → create `pending_event` with status `pending_approval`, notify human admin, return 202.
|
||
|
||
### D.3 — Accepted path (authorized & new)
|
||
|
||
4. **Persist `context_events`**:
|
||
|
||
```sql
|
||
INSERT INTO context_events
|
||
(path, event_type, content, severity, start_time, end_time, created_by, project_id)
|
||
VALUES (?, ?, ?, ?, ?, ?, ?, ?)
|
||
RETURNING id;
|
||
```
|
||
|
||
Return `event_id`.
|
||
|
||
5. **Create graph node + edges**:
|
||
|
||
* `graph_nodes` entry:
|
||
|
||
```sql
|
||
INSERT INTO graph_nodes (node_type, ref_id, label) VALUES ('event', event_id, title) RETURNING id as node_id;
|
||
```
|
||
|
||
* `graph_edges` entries:
|
||
|
||
```sql
|
||
INSERT INTO graph_edges (src_node, dst_node, edge_type) VALUES (agent_node_id, node_id, 'created');
|
||
INSERT INTO graph_edges (src_node, dst_node, edge_type) VALUES (node_id, path_node_id, 'affects_path');
|
||
```
|
||
|
||
(Where `agent_node_id` and `path_node_id` existence is resolved by lookup or created if missing.)
|
||
|
||
6. **Append immutable hyperlog** (append-only)
|
||
|
||
* Hyperlog entry JSON shape:
|
||
|
||
```json
|
||
{
|
||
"type": "context_event",
|
||
"event_id": 123,
|
||
"path": "/src/modules/db/connection",
|
||
"message_type": "blocker",
|
||
"created_by": "alice",
|
||
"timestamp": "2025-08-06T10:12:34Z",
|
||
"idempotency_key": "..."
|
||
}
|
||
```
|
||
|
||
* Hyperlog append function returns `hyperlog_ref = feed_id:offset`. Record that in `context_events.hyperlog_ref`.
|
||
|
||
7. **Publish mesh announcement** (pubsub)
|
||
|
||
* Topic: `bzzz.project.chorus.task.website-redesign`
|
||
* Envelope:
|
||
|
||
```json
|
||
{ "type": "event_announce", "event_id": 123, "path": "/src/modules/...", "message_type": "blocker", "severity": 9 }
|
||
```
|
||
|
||
### D.4 — SLURP Curator reaction
|
||
|
||
SLURP instances subscribe to the project/topic and run the Curator pipeline:
|
||
|
||
1. **Receive announce** → fetch event full payload (if not included) via libp2p / HTTP shim `/get_event?id=123`.
|
||
|
||
2. **Evaluate with `event_type_definitions`** for the project:
|
||
|
||
* lookup `event_type_definitions` for `(project_id, message_type, role)` to find action (`suppress|annotate|notify|route`).
|
||
|
||
3. **Decide**:
|
||
|
||
* If `action == suppress` for certain roles: update `context_events` to set `applies_to_roles` and mark `affected_blobs`.
|
||
* If `action == notify`: enqueue notifications to relevant agents (via pubsub or webhooks).
|
||
* If `severity >= threshold` and `message_type == blocker`:
|
||
|
||
* **Quarantine** blobs: set `quarantine = true` on `context_blobs` where `path LIKE '/src/modules/db/connection%'` and `sensitivity_level` threshold exceeded.
|
||
* Call WHOOSH to run remediation playbook if remediation mapping exists.
|
||
|
||
4. **Log SLURP decision to hyperlog**:
|
||
|
||
```json
|
||
{
|
||
"type": "slurp_decision",
|
||
"event_id": 123,
|
||
"decision": "quarantine_blobs",
|
||
"affected_blob_ids": [42, 43],
|
||
"reason": "blocker severity 9 and project rule says suppress for role frontend",
|
||
"timestamp": "..."
|
||
}
|
||
```
|
||
|
||
5. **Emit post-actions** (if any):
|
||
|
||
* `WHOOSH` run request: push an orchestration event into `automation_queue` table or pubsub topic `bzzz.automation.chorus.website-redesign`.
|
||
* WHOOSH acknowledges and later posts an `automation_result` event (POST) with status; SLURP appends that to hyperlog and optionally updates `context_events` with remediation timestamp.
|
||
|
||
### D.5 — WHOOSH orchestration example
|
||
|
||
If WHOOSH runs an Ansible playbook to rotate keys or replicate a model:
|
||
|
||
* WHOOSH posts a follow-up event:
|
||
|
||
```json
|
||
{
|
||
"message_type": "announcement",
|
||
"title": "Remediation run: rotate_db_creds",
|
||
"content": "Ansible completed key rotation on hosts A,B,C. Affected tokens revoked.",
|
||
"path": "/src/modules/db/connection",
|
||
"created_by": "whoosh",
|
||
"metadata": {"ansible_run_id": "run-321", "status":"success"}
|
||
}
|
||
```
|
||
|
||
* SLURP ingests it and updates `context_events` / hyperlog.
|
||
|

||
## Final notes & recommended next steps
|
||
|
||
**Deliverables prepared here are intended to be actionable**:
|
||
|
||
* **A** is ready to copy into a protocol RFC or OpenAPI doc.
|
||
* **B** is a runnable CLI stub you can expand: signing + HTTP shim integration work immediately.
|
||
* **C** gives you a fast prototype roadmap; use Go + go-libp2p if you want production-grade speed and stability.
|
||
* **D** is the operational recipe your engineering team needs to implement SLURP event handling with exact DB writes, graph updates, hyperlog entries, and WHOOSH orchestration hooks.
|
||
|
||
---
|
||
|
||
### Want me to:
|
||
|
||
* ✍️ Produce the **full OpenAPI YAML** for the shim endpoints (`/post`, `/get`, `/announce`) so you can autogen SDKs?
|
||
* 🔧 Expand the Python shim example to include a tiny in-memory hyperlog and libp2p mock (so you can run an end-to-end demo locally)?
|
||
* 🧩 Draft the Ansible playbook WHOOSH would call for a typical `blocker` remediation (e.g., rotate DB creds + update HCFS metadata)?
|
||
|
||
|
||
|
||
The only thing I'm not convinced on; is the need for querystrings here.
|
||
|
||
|
||
|
||
Nice — I’ll give you two concrete things first, then a robust design for replies + thread coherence that fits your P2P/hyperlog/TGN/SLURP stack.
|
||
|
||
**Deliverables in this message**
|
||
|
||
1. **Formal BNF grammar** for `bzzz://` (clean, canonical).
|
||
2. **libp2p message schema** for the JSON envelope (canonical fields, headers, signing).
|
||
3. **Threading & reply model** — how agents reply to messages, maintain conversation coherence, and how SLURP/WHOOSH use that for actions. Includes storage schema, ordering, conflict handling, replay rules, and security considerations.
|
||
4. **Examples** (sample messages, reply flow, pseudo-code for client and SLURP handling).
|
||
|
||
---
|
||
|
||
## 1) Formal BNF for `bzzz://` (canonical)
|
||
|
||
```
|
||
<uri> ::= "bzzz" "://" <agent> ":" <role> "@" <project> ":" <task> <path> [ "#" <fragment> ]
|
||
|
||
<agent> ::= <id>
|
||
<role> ::= <id>
|
||
<project> ::= <id>
|
||
<task> ::= <id>
|
||
|
||
<path> ::= "/" <segment> { "/" <segment> }
|
||
<segment> ::= <segment-char> { <segment-char> }
|
||
<segment-char> ::= ALPHA | DIGIT | "-" | "_" | "."
|
||
|
||
<fragment> ::= <frag-char> { <frag-char> }
|
||
<frag-char> ::= ALPHA | DIGIT | "-" | "_" | "." | ":"
|
||
|
||
<id> ::= <id-char> { <id-char> }
|
||
<id-char> ::= ALPHA | DIGIT | "-" | "_" | "."
|
||
|
||
ALPHA ::= "A" | "B" | ... | "Z" | "a" | "b" | ... | "z"
|
||
DIGIT ::= "0" | "1" | ... | "9"
|
||
```
|
||
|
||
**Notes**
|
||
|
||
* URIs are case-insensitive for routing; normalized to lowercase for canonical forms.
|
||
* Percent-encode anything outside allowed characters in `segment` / `fragment`.
|
||
* `agent` can be `any` (for anonymous broadcast) but real agents should use stable Decentralized IDs (DIDs) or names mapped to public keys.
|

||
## 2) libp2p Message Schema (JSON) — canonical envelope
|
||
|
||
This is the payload structure transmitted over pubsub / direct streams. Keep it compact and signable.
|
||
|
||
### 2.1 — Top-level envelope (compact JSON)
|
||
|
||
```json
|
||
{
|
||
"hdr": {
|
||
"op": "POST", // GET, POST, PUT, DELETE, ACK, RESP
|
||
"uri": "bzzz://alice:dev@chorus:task/path#v1",
|
||
"msg_id": "uuid-v4",
|
||
"parent_id": "uuid-v4|null", // points to immediate parent message for threads
|
||
"convo_id": "uuid-v4", // conversation identifier (root msg id if absent)
|
||
"ts": "2025-08-06T15:02:00Z", // ISO8601 UTC
|
||
"lamport": 12345, // optional lamport counter
|
||
"ttl": 3600, // seconds; 0 = no-expire (use with care)
|
||
"priority": "normal", // low|normal|urgent
|
||
"agent_pubkey": "base64(pubkey)" // sender's public key for verification
|
||
},
|
||
"meta": {
|
||
"event_type": "blocker", // optional, maps to event enums
|
||
"visibility": {
|
||
"roles": ["frontend","devops"],
|
||
"channels": ["devchat"],
|
||
"exclude": []
|
||
},
|
||
"project": "chorus",
|
||
"task": "website-redesign"
|
||
},
|
||
"payload": { // free-form content, may include structured fields
|
||
"title": "Hardcoded DB creds",
|
||
"body": "Detected DB creds in repo. Rotate immediately.",
|
||
"attachments": [
|
||
{ "type": "blob-ref", "hash": "sha256:..." }
|
||
],
|
||
"hints": { "use_lightrag": true } // optional operational hints
|
||
},
|
||
"sig": "base64(signature)" // signature over canonical_hdr + payload
|
||
}
|
||
```
|
||
|
||
### 2.2 — Canonical signing
|
||
|
||
* **What to sign:** canonicalized JSON of `hdr` + `meta` + `payload` in deterministic key order (e.g., RFC8785 or JCS canonical form).
|
||
* **Signature scheme:** Ed25519 (or COSE/COSE2 if you want richer structures). Include `agent_pubkey` so receiver can verify.
|
||
* **Idempotency:** clients generate `msg_id` UUID v4 and re-send on retry; server checks for duplicates.
|
||
|
||
### 2.3 — Minimal ACK / Response envelope
|
||
|
||
* For fast ACKs/minimal replies:
|
||
|
||
```json
|
||
{

## 3) Threading & Reply Model — design
|
||
|
||
Goals:
|
||
|
||
* Keep thread structure explicit, replayable, verifiable.
|
||
* Support branching conversations, parallel replies, follow-ups.
|
||
* Allow SLURP and TGN to reason about conversation coherence and detect divergence.
|
||
|
||
### 3.1 — Core primitives
|
||
|
||
**msg\_id** — unique message identifier (UUID v4).
|
||
**parent\_id** — immediate parent message (null for root).
|
||
**convo\_id** — conversation identifier; for a new thread, `convo_id = msg_id` of root; replies inherit convo\_id.
|
||
**lamport** — optional logical counter to help ordering across peers. Each agent increments before sending; merge rules use lamport + ts.
|
||
**ts** — wall-clock timestamp in UTC (for human readability and approximate ordering).
|
||
**signature** — verifies authenticity & integrity.
|
||
**visibility** — roles/channels control who should see the message.
|
||
|
||
### 3.2 — Thread coherence rules
|
||
|
||
1. **Canonical thread root**: When starting a thread, `convo_id = msg_id`. All replies set `convo_id` to root id. This lets you quickly fetch the entire conversation: `SELECT * FROM messages WHERE convo_id = <root> ORDER BY lamport, ts`.
|
||
|
||
2. **Parent linkage**: `parent_id` forms a tree. Use this for fast tree traversal and reconstructing reply chains, branching points, and ancestors.
|
||
|
||
3. **Ordering**:
|
||
|
||
* **Preferred ordering**: `(lamport, ts)` ascending. Lamport gives causal order; ts helps human-ordered chronology.
|
||
* **Tie-breaker**: `msg_id` lexicographic order for total order.
|
||
* **Delivery ordering**: pubsub doesn’t guarantee ordering; receivers must reorder using lamport & parent relationships.
|
||
|
||
4. **Causal consistency**:
|
||
|
||
* When agent A replies to message M, it must set `parent_id = M.msg_id`, and ensure its `lamport` > lamport of M (if known). If unknown, agent may read latest lamport for M or use local lamport +1.
|
||
* If an agent receives reply R before M (possible in P2P), they store R in a pending table keyed by `parent_id` and once M arrives, link them.
|
||
|
||
5. **Thread reconciliation on forks**:
|
||
|
||
* Branching is expected (parallel replies). UI and SLURP should show branches; TGN can detect divergence if branches move on different actions.
|
||
* For conflicting "decision" messages (e.g., two approvals with different payloads), SLURP can apply deterministic conflict-resolution rules (highest priority event\_type, then latest lamport, then human escalation). Keep conflicts explicitly logged.
|
||
|
||
6. **Message lifecycle**:
|
||
|
||
* Messages are appended immutably to hyperlog. "Deletion" is a new tombstone message (`op=DELETE` with parent pointing to resource) — append-only history preserved.
|
||
* Edit flows: editing a message results in a new `PUT` message with `parent_id` pointing to the original; store versions.
|
||
|
||
### 3.3 — Conversation metadata & summarization
|
||
|
||
SLURP maintains per-conversation metadata in DB:
|
||
|
||
* `convo_id`, `root_msg_id`, `participants` (agent list), `last_activity_ts`, `state` (open/closed/escalated), `drift_score`, `summary_blob_id`.
|
||
|
||
On receiving messages, SLURP:
|
||
|
||
* Updates convo `last_activity_ts`.
|
||
* Recomputes a short summary every N messages or if event\_type == decision/blocker.
|
||
* Stores the summary (and TGN embedding) for quick retrieval.
|
||
|
||
TGN uses message edges as temporal edges:
|
||
|
||
* Node types: message nodes, agent nodes, path nodes.
|
||
* Edges: `reply_to`, `authored_by`, `affects_path`, with timestamps.
|
||
* TGN embeddings help cluster threads, detect drift, and propose thread summarization.
|
||
|
||
### 3.4 — Subscriptions & delivery guarantees
|
||
|
||
* Pubsub topics are per `project:task` swarm. Consumers subscribe to `bzzz.project.<project>.task.<task>`.
|
||
* Message delivery: pubsub announce includes the `hdr` and optionally small payload. For large payloads, announce contains `blob_ref` (content-addressed hash) and peers fetch via direct stream.
|
||
* Clients maintain **receipt logs** (ACKs) — receiver returns `ACK` to sender (or via pubsub) so sender knows which peers got it. For broadcast messages requiring stronger guarantee (e.g., revocation), SLURP may require quorum ACKs (N out of M agents).
|
||
|
||
### 3.5 — Storage schema (messages table) — Postgres/SQLite
|
||
|
||
```sql
|
||
CREATE TABLE messages (
|
||
msg_id TEXT PRIMARY KEY,
|
||
convo_id TEXT NOT NULL,
|
||
parent_id TEXT,
|
||
uri TEXT, -- the bzzz:// resource targeted
|
||
op TEXT, -- POST/GET/ACK/RESP/PUT/DELETE
|
||
hdr JSONB, -- raw header storage
|
||
meta JSONB, -- event_type, visibility, etc.
|
||
payload JSONB,
|
||
agent_pubkey TEXT,
|
||
lamport BIGINT,
|
||
ts TIMESTAMPTZ,
|
||
hyperlog_ref TEXT, -- pointer to immutable hyperlog entry
|
||
signature TEXT
|
||
);
|
||
|
||
CREATE INDEX idx_messages_convo ON messages(convo_id);
|
||
CREATE INDEX idx_messages_parent ON messages(parent_id);
|
||
CREATE INDEX idx_messages_uri ON messages(uri);
|
||
CREATE INDEX idx_messages_ts ON messages(ts);
|
||
```
|
||
|
||
Hyperlog append stores the same JSON in append-only feed, and `hyperlog_ref` links to it. You can reconstruct message history from hyperlog or DB.
|
||
|

|
||
|
||
## 4) Reply flow examples & pseudo-code
|
||
|
||
### 4.1 — Simple reply (agent client behavior)
|
||
|
||
**Action:** Developer receives a blocker message, replies with an ACK and follow-up.
|
||
|
||
Pseudocode:
|
||
|
||
```python
|
||
# local lamport counter
|
||
lamport = load_local_lamport()
|
||
|
||
def send_reply(parent_msg, uri, payload, op="RESP"):
|
||
global lamport
|
||
lamport = max(lamport, parent_msg.get('lamport', 0)) + 1
|
||
msg = {
|
||
"hdr": {
|
||
"op": op,
|
||
"uri": uri,
|
||
"msg_id": str(uuid4()),
|
||
"parent_id": parent_msg['msg_id'],
|
||
"convo_id": parent_msg['convo_id'],
|
||
"ts": utc_now(),
|
||
"lamport": lamport,
|
||
"agent_pubkey": my_pubkey_b64
|
||
},
|
||
"meta": { "event_type": "info" },
|
||
"payload": payload
|
||
}
|
||
msg['sig'] = sign_msg(msg)
|
||
pubsub_publish(topic_for(parent_msg['meta']['project'], parent_msg['meta']['task']), msg)
|
||
append_hyperlog(msg) # local append for history & replay
|
||
```
|
||
|
||
**When receiving messages**, client must:
|
||
|
||
* Verify signature.
|
||
* Store message in DB and hyperlog.
|
||
* If `parent_id` missing (child before parent), put into `pending_children[parent_id]`.
|
||
* If parent later arrives, attach and bubble up.
|
||
|
||
### 4.2 — SLURP reaction to reply messages
|
||
|
||
SLURP subscribes to project topic.
|
||
|
||
On receipt:
|
||
|
||
1. Verify signature & visibility.
|
||
2. Persist message (messages table) + hyperlog append.
|
||
3. If `op` == `POST` and `event_type` == `blocker`:
|
||
|
||
* Evaluate project `event_type_definitions` -> action.
|
||
* If action == `quarantine`, mark affected blobs & create `slurp_decision` entry & hyperlog record.
|
||
* Trigger WHOOSH orchestration if remediation required.
|
||
4. If `op` == `RESP` or `ACK`:
|
||
|
||
* Update `messages` table state for the referenced msg\_id (e.g., mark acknowledged).
|
||
* Optionally re-evaluate whether the blocker is resolved (if `RESP` payload includes `resolution=true`).
|
||
5. Update convo summary & TGN embedding.
|
||
|
||
Pseudo:
|
||
|
||
```python
|
||
def handle_msg(msg):
|
||
verify(msg)
|
||
insert_messages_table(msg)
|
||
hyperlog_append(msg)
|
||
if msg.hdr.op == "POST" and msg.meta.event_type == "blocker":
|
||
action = lookup_action(msg.meta.project, "blocker", role=... )
|
||
if action == "quarantine":
|
||
affected = find_blobs_under_path(msg.payload.path)
|
||
quarantine_blobs(affected, reason="blocker")
|
||
log_slurp_decision(msg, affected)
|
||
whoosh_trigger_remediation(affected)
|
||
elif msg.hdr.op in ("RESP", "ACK"):
|
||
update_message_ack(msg.parent_id, msg)
|
||
maybe_resolve_blocker(msg.parent_id)
|
||
# update convo metadata
|
||
update_convo(msg.convo_id, last_activity=msg.hdr.ts)
|
||
tgn_ingest(msg) # add temporal edge for TGN
|
||
```
|
||
|
||
### 4.3 — Thread coherence & TGN usage
|
||
|
||
* **TGN ingestion**: each message creates edges (agent -> message: authored\_by; message -> path: affects\_path; message -> message: reply\_to). Timestamps are the message ts.
|
||
* **TGN tasks**:
|
||
|
||
* Detect threads drifting (e.g., replies reference different resources over time).
|
||
* Cluster replies that are semantically related via embeddings.
|
||
* Suggest merge candidates or escalate to human if branches diverge (e.g., some replies recommend conflicting actions).
|
||
* **SLURP uses TGN outputs** to:
|
||
|
||
* Re-rank which threads to surface to humans (e.g., high-drift critical threads).
|
||
* Suggest thread summaries.
|
||
|
||
---
|
||
|
||
## 5) Conflict resolution & decision authority
|
||
|
||
Design choices:
|
||
|
||
* **Deterministic policy**: for conflicting decisions (e.g., two approvals), choose the one with higher priority, or later lamport if priority equal. Log the override.
|
||
* **Human override**: if conflict cannot be safely auto-resolved, SLURP sets `state=escalated` and notifies owners.
|
||
* **Audit trail**: every override, conflict, and merge is appended to hyperlog with reason and signatures.
|
||
|
||
---
|
||
|
||
## 6) Scaling, pruning, and GC
|
||
|
||
* **Retention policy**: projects define how long hyperlog feeds are kept locally. Use content-addressed storage (CAR files or chunk stores) for older archives.
|
||
* **Pruning**: nodes may garbage-collect message bodies older than X days but must preserve minimal hyperlog index (msg\_id, hyperlog\_ref) to reconstruct from archive peers.
|
||
* **Archival nodes**: designate some nodes to keep full immutable history (for compliance), others keep working window.
|
||
* **Snapshotting**: periodically SLURP writes convo snapshots (summary + representative blobs) to reduce replay cost.
|
||
|
||
---
|
||
|
||
## 7) Privacy & security considerations
|
||
|
||
* **Visibility metadata** controls who should receive message payloads. Pubsub announces may include only metadata and blob hashes; payloads are fetched only by authorized peers.
|
||
* **End-to-end encryption** of payloads: use per-project symmetric keys encrypted for authorized roles, or use public-key envelopes (e.g., encrypt to set of role public keys). Keep metadata in plaintext (or signed) for routing.
|
||
* **Signature & key rotation**: support key revocation events; SLURP verifies signature chain and consults agent registry.
|
||
* **Redaction**: for high-sensitivity payloads, only send redacted previews on pubsub announcements; full content via direct encrypted stream after ACL check.
|
||
|
||
---
|
||
|
||
## 8) Replay & determinism
|
||
|
||
* Because everything is appended with signatures, you can **replay** a convo deterministically by replaying hyperlog entries in order. When replaying:
|
||
|
||
* Recompute lamport counters in order.
|
||
* Restore convo states, Slurp decisions, TGN ingestions.
|
||
* For experiments, you can replay with alternative SLURP policies and compare outcomes (A/B).
|
||
|
||
---
|
||
|
||
## 9) Example end-to-end scenario
|
||
|
||
**1. Alice posts blocker**
|
||
|
||
* Alice sends POST envelope; publishes to pubsub. SLURP persists, appends hyperlog, quarantines blobs, triggers WHOOSH.
|
||
|
||
**2. Bob (frontend) receives announcement**
|
||
|
||
* Bob’s local shim fetches announce, gets header. Since Bob has no access to DB credentials, SLURP's visibility suppressed full content; Bob receives annotated blocker with action instructions.
|
||
|
||
**3. DevOps replies with remediation update**
|
||
|
||
* DevOps posts RESP with `parent_id = alice.msg_id` and payload `{ "resolution": true, "details": "Keys rotated" }`. SLURP marks blocker resolved, appends hyperlog, notifies participants.
|
||
|
||
**4. SLURP updates convo summary & TGN**
|
||
|
||
* SLURP runs an incremental summarizer, stores summary as blob, and TGN updates embeddings to note a resolved blocker and the participants.
|
||

|
||
|
||
## Final notes & next steps
|
||
|
||
I’ve given you:
|
||
|
||
* Formal grammar
|
||
* Compact libp2p JSON envelope and signing rules
|
||
* A full threading & reply model with DB schema
|
||
* Pseudocode and operational rules for SLURP & WHOOSH processing
|
||
* Security, replay, GC, and TGN integration points
|
||
|
||
If you want I can:
|
||
|
||
* **Generate a concrete OpenAPI spec** for the HTTP shim endpoints that accept these envelopes (for BZZZ CLI to talk to shim).
|
||
* **Write a minimal Go or Python shim prototype** that runs libp2p pubsub + HTTP endpoints and implements the message handling (including verifying signatures and appending to a SQLite hyperlog).
|
||
* **Produce a client library** (Python) that handles lamport counters, signing, parent tracking, and pending-child attachment logic.
|
||
|
||
|
||
Great — I’ll give you two deliverables, in order:
|
||
|
||
1. **OpenAPI 3.0 spec** for the local HTTP shim (endpoints `/post`, `/get`, `/announce`, `/sub`) so clients (CLI, SDKs) can autogen clients and understand the envelope.
|
||
2. **Go prototype** (runnable) for the shim that:
|
||
|
||
* runs a libp2p node (pubsub)
|
||
* exposes the HTTP endpoints
|
||
* verifies Ed25519 signatures
|
||
* appends messages to a simple SQLite-based hyperlog
|
||
* publishes/receives pubsub announces
|
||
* is intentionally minimal so you can extend it quickly (LightRAG/TGN/SLURP hooks are left as TODOs)
|
||
|
||
I’ll keep the Go code compact but complete enough to run locally on a LAN. After the code I’ll include **how to build & run**, and suggestions for testing.

## Part 2 — Go prototype shim
|
||
|
||
Below is a compact but runnable Go prototype. It uses:
|
||
|
||
* **go-libp2p** for peer/pubsub (basic usage)
|
||
* **mattn/go-sqlite3** for SQLite hyperlog
|
||
* **golang.org/x/crypto/ed25519** for signature verification
|
||
* **gorilla/mux** for HTTP routing (simple)
|
||
* Note: go-libp2p and pubsub code is slightly simplified for clarity — this is a working starting point but you should adapt and harden for production.
|
||

## How to build & run the prototype
|
||
|
||
1. **Install Go** (1.20+).
|
||
2. **Create project folder** and put `go.mod` and `main.go` there.
|
||
3. **Get modules**:
|
||
|
||
```bash
|
||
go mod tidy
|
||
```
|
||
|
||
4. **Build**:
|
||
|
||
```bash
|
||
go build -o bzzz-shim
|
||
```
|
||
|
||
5. **Run**:
|
||
|
||
```bash
|
||
./bzzz-shim
|
||
```
|
||
|
||
This starts an HTTP shim on `:19000` and a libp2p node with basic pubsub.
|
||
|
||
---
|
||
|
||
## Quick test with `curl`
|
||
|
||
**POST a minimal envelope** (you'll need a real Ed25519 signature for the proto's verify step — for quick test, either bypass verify by commenting out `verifyEnvelope` call in code, or sign payloads properly):
|
||
|
||
```bash
|
||
curl -X POST http://localhost:19000/post -H "Content-Type: application/json" \
|
||
-d '{
|
||
"hdr": {"op":"POST","uri":"bzzz://any:dev@chorus:task/path","msg_id":"1111-2222","convo_id":"1111-2222","ts":"2025-08-06T15:00:00Z","agent_pubkey":"<base64pub>"},
|
||
"meta": {"event_type":"blocker","project":"chorus","task":"task"},
|
||
"payload": {"title":"test","body":"please rotate keys"},
|
||
"sig":"<base64sig>"
|
||
}'
|
||
```
|
||
|
||
If signature verification is disabled for a dev run, the shim will accept and append the hyperlog and publish to the pubsub topic (`bzzz.project.chorus.task.task`).
|
||
|
||

|
||
|
||
## Notes, caveats, and next steps
|
||
|
||
* **Canonical signing**: The prototype uses `json.Marshal` for the canonical payload — this is *not* deterministic. In production, use canonical JSON (RFC8785 / JCS) or COSE/CBOR for signing. Libraries exist for canonical JSON signing in Go.
|
||
* **Libp2p tuning**: `go-libp2p` requires configuration for NAT traversal, bootstrap peers, and peerstore persistence; the code uses a default host for local testing.
|
||
* **Pubsub topics**: The code currently publishes minimal announcements. For big payloads you should publish `blob_ref` and stream payloads over direct streams.
|
||
* **Hyperlog**: For a real immutable hyperlog use Hypercore (JS) or similar append-only stores. For this prototype, SQLite provides a simple append table with `hyperlog_ref` pointer.
|
||
* **Security**: Use proper key management and rotate keys. Consider E2E encryption for private payloads.
|
||
* **Extensibility**: Hook SLURP logic into `handlePost` (after appendHyperlog) to trigger curation decisions and WHOOSH orchestration.
|
||
|
||
---
|
||
|
||
### Want me to follow up with:
|
||
|
||
* A **Go implementation that actually performs Ed25519 signing for test clients** (generate keys + sign payloads) and a small test script to POST a valid envelope?
|
||
* **Dockerfile + docker-compose** to run multiple shim instances in a local network and see pubsub announces propagate?
|
||
* **Add hyperlog replay & a small SLURP plugin** to demo quarantine-on-blocker behavior?
|
||
|
||
|
||
|
||
Awesome — love your energy. I’ll give you three practical artifacts and clear run steps so you can try this end-to-end quickly:
|
||
|
||
1. **Go test client** that generates an Ed25519 keypair, canonicalizes an envelope, signs it, and POSTs to the shim.
|
||
2. **Docker Compose** (bootstrap + 2 worker shim instances) with a small helper to extract the bootstrap multiaddr and start the cluster.
|
||
3. **Hyperlog replay + tiny SLURP plugin** added to the shim prototype: a `/replay` HTTP endpoint that replays hyperlog messages in order and demonstrates *quarantine-on-blocker* behavior (marks matching `context_blobs` as quarantined and logs SLURP decisions).
|
||
|
||
I’ll include code + instructions for building and running. I keep things intentionally simple and prototype-ready — production hardening (key management, canonical JSON libraries, libp2p bootstrap resiliency, E2E encryption, etc.) is called out as next steps.
|
||
|
||
---
|
||
|
||
## A — Go test client (sign + POST)
|
||
|
||
**File:** `client/sign_and_post.go`
|
||
|
||
This client:
|
||
|
||
* Generates an Ed25519 keypair and writes the private key locally (so you can reuse it).
|
||
* Builds a deterministic (stable) canonical payload for signing by producing a JSON object where keys are marshaled in stable order.
|
||
* Signs the canonical bytes and posts envelope to `http://localhost:19000/post`.
|
||
|
||
> Note: For canonical JSON we use a simple deterministic helper that sorts map keys recursively. This is fine for prototype. For production use RFC8785 / JCS canonicalization.

|
||
|
||
**Notes:**
|
||
|
||
* Save as `client/sign_and_post.go`. `go run` it.
|
||
* This client writes a private key to `./client.key`. Re-run will re-use it.
|
||
* **Important**: The shim in the earlier prototype validated signatures by marshaling hdr+meta+payload with `json.Marshal` — this client uses a deterministic `stableMarshal` to match that (so signature verifies). The shim code should be updated to use the same stable canonicalization (I’ll show how below).

|
||
## B — Docker Compose (bootstrap + 2 workers)
|
||
|
||
Because libp2p requires knowing a bootstrap peer to join a swarm in Docker, this `docker-compose` runs **one bootstrap shim** with a fixed port and writes its multiaddr to a file. Then two worker shims are started with an environment var `BOOTSTRAP_PEER` (provided by a small startup helper script) to connect to bootstrap. There’s a tiny orchestration script to capture bootstrap peer info and export it when starting the workers.
|
||
|
||
**Files:**
|
||
|
||
### `docker-compose.yml`
|
||
|
||
```yaml
|
||
version: "3.8"
|
||
services:
|
||
bootstrap:
|
||
build: .
|
||
container_name: bzzz-shim-bootstrap
|
||
environment:
|
||
- ROLE=bootstrap
|
||

|
||

|
||

|
||
worker1:
|
||

|
||
container_name: bzzz-shim-worker1
|
||
environment:
|
||

|
||

|
||
- DB_PATH=/data/worker1.db
|
||
- BOOTSTRAP_PEER=${BOOTSTRAP_PEER}
|
||
depends_on:
|
||
- bootstrap
|
||
worker2:
|
||
build: .
|
||
container_name: bzzz-shim-worker2
|
||
environment:
|
||

|
||

- DB_PATH=/data/worker2.db
|
||
- BOOTSTRAP_PEER=${BOOTSTRAP_PEER}
|
||
depends_on:
|
||
- bootstrap
|
||
```
|
||
|
||
### `bootstrap-peer-helper.sh` — workflow to start and capture multiaddr
|
||
|
||
```bash
|
||
#!/usr/bin/env bash
|
||
set -e
|
||
echo "Bringing up bootstrap..."
|
||
docker-compose up -d bootstrap
|
||
sleep 3
|
||
|
||
# grab multiaddr from bootstrap container logs (we'll print it in shim logs)
|
||
echo "Waiting for bootstrap to emit multiaddr..."
|
||
BOOTSTRAP_ADDR=""
|
||
for i in {1..15}; do
|
||
BOOTSTRAP_ADDR=$(docker logs bzzz-shim-bootstrap 2>&1 | grep "Libp2p host listening at" -m1 | awk -F' ' '{print $NF}')
|
||
if [ -n "$BOOTSTRAP_ADDR" ]; then break; fi
|
||
sleep 1
|
||
done
|
||
|
||
if [ -z "$BOOTSTRAP_ADDR" ]; then
|
||
echo "Could not find bootstrap multiaddr in logs. Check bootstrap logs."
|
||
docker logs bzzz-shim-bootstrap
|
||
exit 1
|
||
fi
|
||
|
||
echo "Bootstrap multiaddr: $BOOTSTRAP_ADDR"
|
||
export BOOTSTRAP_PEER="$BOOTSTRAP_ADDR"
|
||
echo "Starting workers with BOOTSTRAP_PEER=$BOOTSTRAP_PEER"
|
||
BOOTSTRAP_PEER="$BOOTSTRAP_PEER" docker-compose up -d worker1 worker2
|
||
echo "All services started."
|
||
```
|
||
|
||
**Notes & limitations**
|
||
|
||
* The shim must print its listen multiaddr line like: `Libp2p host listening at /ip4/172.18.0.2/tcp/4001/p2p/<peerid>` to logs; the helper scrapes logs for that string.
|
||
* Depending on Docker network timings, you might need to adjust sleeps.
|
||
* This setup is for dev/demo; production should use persistent peerstore and well-known bootstrap nodes.

||
|
||
## C — Hyperlog replay & SLURP plugin (quarantine-on-blocker)
|
||
|
||
Additions to the shim prototype (`main.go`) to enable:
|
||
|
||
1. `context_blobs` table (simple prototype) — stores blobs and a `quarantine` boolean.
|
||
2. `/replay` endpoint — iterates all messages in `messages` table ordered by `rowid` (chronological append), and for each `POST` with `event_type=blocker` it will mark `context_blobs` under the event `path` as quarantined and append a `slurp_decision` message to the hyperlog.
|
||
|
||
### SQL additions (run once or included in initDB)
|
||
|
||
```sql
|
||
CREATE TABLE IF NOT EXISTS context_blobs (
|
||
id INTEGER PRIMARY KEY AUTOINCREMENT,
|
||
path TEXT,
|
||
role TEXT,
|
||
channel TEXT,
|
||
content TEXT,
|
||
priority INTEGER DEFAULT 5,
|
||
created_at TEXT,
|
||
quarantine INTEGER DEFAULT 0
|
||
);
|
||
|
||
CREATE TABLE IF NOT EXISTS slurp_decisions (
|
||
id INTEGER PRIMARY KEY AUTOINCREMENT,
|
||
event_msg_id TEXT,
|
||
decision TEXT,
|
||
affected_blobs TEXT, -- JSON array
|
||
reason TEXT,
|
||
ts TEXT
|
||
);
|
||
```
|
||
|
||
Add these in the existing `initDB` function or run a migration script.
|
||
|
||
### `/replay` endpoint handler (pseudo-implementation for main.go)
|
||
|
||
Add function:
|
||
|
||
```go
|
||
func handleReplay(w http.ResponseWriter, r *http.Request) {
|
||
// iterate messages in order of rowid
|
||
rows, err := db.Query("SELECT rowid, msg_id, hdr, meta, payload FROM messages ORDER BY rowid ASC")
|
||
if err != nil {
|
||
http.Error(w, "db error", 500); return
|
||
}
|
||
defer rows.Close()
|
||
var decisions []map[string]interface{}
|
||
for rows.Next() {
|
||
var rowid int64
|
||
var msgID, hdrStr, metaStr, payloadStr string
|
||
if err := rows.Scan(&rowid, &msgID, &hdrStr, &metaStr, &payloadStr); err != nil { continue }
|
||
// parse meta to check event_type and path
|
||
var meta, payload map[string]interface{}
|
||
json.Unmarshal([]byte(metaStr), &meta)
|
||
json.Unmarshal([]byte(payloadStr), &payload)
|
||
et, _ := meta["event_type"].(string)
|
||
if et == "blocker" {
|
||
// extract path from payload or meta
|
||
path := ""
|
||
if p, ok := payload["path"].(string); ok { path = p }
|
||
if path == "" {
|
||
if p2, ok := meta["path"].(string); ok { path = p2 }
|
||
}
|
||
if path == "" { continue }
|
||
// quarantine any context_blobs where path LIKE path || "%"
|
||
res, err := db.Exec("UPDATE context_blobs SET quarantine = 1 WHERE path LIKE ? || '%'", path)
|
||
if err == nil {
|
||
cnt, _ := res.RowsAffected()
|
||
reason := fmt.Sprintf("quarantine due to blocker event %s", msgID)
|
||
// store decision
|
||
affected := []int64{}
|
||
// find ids of affected blobs
|
||
rows2, _ := db.Query("SELECT id FROM context_blobs WHERE path LIKE ? || '%'", path)
|
||
for rows2.Next() {
|
||
var id int64
|
||
rows2.Scan(&id)
|
||
affected = append(affected, id)
|
||
}
|
||
rows2.Close()
|
||
affJSON, _ := json.Marshal(affected)
|
||
ts := time.Now().UTC().Format(time.RFC3339)
|
||
db.Exec("INSERT INTO slurp_decisions (event_msg_id, decision, affected_blobs, reason, ts) VALUES (?, ?, ?, ?, ?)",
|
||
msgID, "quarantine", string(affJSON), reason, ts)
|
||
decisions = append(decisions, map[string]interface{}{"event": msgID, "affected": affected})
|
||
}
|
||
}
|
||
}
|
||
resp := map[string]interface{}{"status":"replayed","decisions":decisions}
|
||
w.Header().Set("Content-Type","application/json")
|
||
json.NewEncoder(w).Encode(resp)
|
||
}
|
||
```
|
||
|
||
Register the handler:
|
||
|
||
```go
|
||
r.HandleFunc("/replay", handleReplay).Methods("POST")
|
||
```
|
||
|
||
### How demo works
|
||
|
||
1. Start shim(s).
|
||
2. Post a few context blobs (toy entries) directly to shim DB (or via HTTP POST envelopes with `op: POST` where payload indicates it's a blob). Example blob row insert:
|
||
|
||
```sql
|
||
INSERT INTO context_blobs (path, role, channel, content, created_at) VALUES ('/src/modules/db/connection','backend','dev','DB creds are stored here',datetime('now'));
|
||
```
|
||
|
||
3. Use the client to POST a blocker event that covers `/src/modules/db/connection` (as earlier client did).
|
||
4. Call `POST /replay` on the shim:
|
||
|
||
```bash
|
||
curl -X POST http://localhost:19000/replay
|
||
```
|
||
|
||
5. Shim will scan messages, find the blocker, and mark matching context\_blobs as `quarantine=1`. It will insert entries into `slurp_decisions` that record what was quarantined and why.
|
||
|
||
6. Inspect DB:
|
||
|
||
```bash
|
||
sqlite3 bzzz_hyperlog.db "SELECT id, path, quarantine FROM context_blobs;"
|
||
sqlite3 bzzz_hyperlog.db "SELECT * FROM slurp_decisions;"
|
||
```
|
||
|
||
This demonstrates the SLURP plugin behavior: **on replay (or in real-time when messages are appended), SLURP can quarantine context based on high-severity events** and log decisions.
|
||
|
||
---
|
||
|
||
## How to run everything — quickstart
|
||
|
||
1. **Build shim** (in `bzzz-shim` directory)
|
||
|
||
```bash
|
||
go mod tidy
|
||
go build -o bzzz-shim
|
||
```
|
||
|
||
2. **Start bootstrap and workers (docker method)**
|
||
|
||
```bash
|
||
chmod +x bootstrap-peer-helper.sh
|
||
./bootstrap-peer-helper.sh
|
||
# wait for outputs; it starts bootstrap then workers
|
||
```
|
||
|
||
3. **Start local shim (standalone) for quick test**
|
||
|
||
```bash
|
||
./bzzz-shim
|
||
# starts HTTP on :19000
|
||
```
|
||
|
||
4. **Run client to POST signed blocker**
|
||
|
||
```bash
|
||
go run client/sign_and_post.go --shim http://localhost:19000
|
||
```
|
||
|
||
5. **Seed a context blob (sqlite direct insert for quick demo)**
|
||
|
||
```bash
|
||
sqlite3 bzzz_hyperlog.db "INSERT INTO context_blobs (path, role, channel, content, created_at) VALUES ('/src/modules/db/connection','backend','dev','DB creds here', datetime('now'));"
|
||
```
|
||
|
||
6. **Replay to run SLURP quarantines**
|
||
|
||
```bash
|
||
curl -X POST http://localhost:19000/replay
|
||
```
|
||
|
||
7. **Inspect DB**
|
||
|
||
```bash
|
||
sqlite3 bzzz_hyperlog.db "SELECT id,path,quarantine FROM context_blobs;"
|
||
sqlite3 bzzz_hyperlog.db "SELECT * FROM slurp_decisions;"
|
||
```
|
||

|
||
|
||
## Next steps & prod hardening checklist
|
||
|
||
If you want to move from prototype → hardened POC / production, next items to tackle:
|
||
|
||
* Use a canonical JSON library (JCS / RFC8785) for deterministic signing and verification.
|
||
* Persist libp2p peerstore and provide robust bootstrapping (bootstrap nodes, NAT traversal).
|
||
* Switch hyperlog to an append-only content-addressed store (Hypercore, IPFS CAR, etc.) for immutability guarantees.
|
||
* Implement role-based encryption for payloads (project keys + per-role key wrapping).
|
||
* Add TLS & mTLS to shim HTTP endpoints (protect local API).
|
||
* Add metrics, observability, rate-limiting, and authorization middleware for the shim.
|
||
|
||
---
|
||
|
||
If you want I can:
|
||
|
||
* **(a)** produce the exact patched `main.go` with `/replay` + the DB schema changes (complete file).
|
||
* **(b)** produce a Dockerfile for the shim image (so `docker-compose` build works).
|
||
* **(c)** generate a small demo script that automates: build shim image, start bootstrap, start workers, run client, seed blob, replay, and show results.
|
||
|
||
Nice — I’ll give you everything you need to run a quick end-to-end demo:
|
||
|
||
* **(B)** a `Dockerfile` for the shim image (builds the Go binary and runs it)
|
||
* **(C)** a `docker-compose.yml` (bootstrap + 2 workers) and a `demo.sh` script that:
|
||
|
||
1. builds the shim image,
|
||
2. starts bootstrap,
|
||
3. waits for the bootstrap libp2p multiaddr,
|
||
4. starts workers (pointing them to the bootstrap peer),
|
||
5. runs the local Go test client to POST a signed blocker to the bootstrap shim,
|
||
6. seeds a test `context_blob` into the bootstrap SQLite DB,
|
||
7. calls `/replay` on the bootstrap shim to trigger SLURP quarantine behavior,
|
||
8. prints the `context_blobs` table to show quarantine was applied.
|
||
|
||
Everything is intentionally simple and prototype-ready. You’ll need **Docker**, **docker-compose**, and **Go 1.20+** on the host.
|
||
|
||
---
|
||
|
||
## A — `Dockerfile` (shim image)
|
||
|
||
Save as `Dockerfile` in your `bzzz-shim` project folder (next to `main.go` and `go.mod`).
|
||
|
||
```dockerfile
|
||
# Build stage
|
||
FROM golang:1.20-buster AS builder
|
||
WORKDIR /src
|
||
|
||
# Copy sources
|
||
COPY go.mod go.sum ./
|
||
RUN go mod download
|
||
|
||
COPY . .
|
||
# Build the shim
|
||
RUN CGO_ENABLED=1 GOOS=linux GOARCH=amd64 go build -o /out/bzzz-shim
|
||
|
||
# Final runtime image
|
||
FROM debian:buster-slim
|
||
RUN apt-get update && apt-get install -y sqlite3 ca-certificates && rm -rf /var/lib/apt/lists/*
|
||
WORKDIR /app
|
||
# copy binary
|
||
COPY --from=builder /out/bzzz-shim /usr/local/bin/bzzz-shim
|
||
|
||
# create data dir
|
||
RUN mkdir -p /data
|
||
VOLUME ["/data"]
|
||
EXPOSE 19000
|
||
|
||
ENTRYPOINT ["/usr/local/bin/bzzz-shim"]
|
||
```
|
||
|
||
Notes:
|
||
|
||
* The container includes `sqlite3` so the demo script can `docker exec` into containers to run SQL commands.
|
||
* Binary is built in the builder stage; final image is minimal.
|
||
|

|
||
|
||
## B — `docker-compose.yml`
|
||
|
||
Save next to the `Dockerfile`.
|
||
|
||
```yaml
|
||
version: "3.8"
|
||

|
||
|
||
networks:
|
||
bzzz-net:
|
||
driver: bridge
|
||
```
|
||
|
||
Notes:
|
||
|
||
* `bootstrap` port 19000 is mapped to host so the local test client can POST to `http://localhost:19000/post`.
|
||
* Workers will be started by the `demo.sh` script after we scrape the bootstrap peer's multiaddr.

## C — `demo.sh` — bootstrap + run client + replay
|

Save this script in the repo root (`demo.sh`) and `chmod +x demo.sh`.

```bash

**Important notes on `demo.sh` usage**
|
||
|
||
* The script expects:
|
||
|
||
* `client/sign_and_post.go` compiled client binary (the script tries to build it). If you put the client code at `client/sign_and_post.go` it will attempt to build `./client_post`.
|
||
* The shim `main.go` prints a libp2p listen line containing a `/ip4/.../p2p/<peerid>` multiaddr so the script can scrape it. If your shim prints something else, adjust the `grep` in the script.
|
||
* If the shim’s `verifyEnvelope` requires exact canonicalization to verify the client's signature, ensure the client uses the same canonicalizing routine. The client code I supplied earlier uses `stableMarshal`, and you should make your shim verify using the same canonicalization (or temporarily disable verification while testing).
|
||
|
||
---
|
||
|
||
## Quick checklist / commands
|
||
|
||
From the `bzzz-shim` repo root:
|
||
|
||
```bash
|
||
# 1) ensure you have Docker & docker-compose & Go installed
|
||
|
||
# 2) place Dockerfile, docker-compose.yml, demo.sh in repo root (alongside main.go & client/)
|
||
chmod +x demo.sh
|
||
|
||
# 3) run demo
|
||
./demo.sh
|
||
```
|
||
|
||
After run:
|
||
|
||
* The script will print the `context_blobs` table rows showing `quarantine=1` for blobs under the event path if the replay SLURP logic matched them.
|
||
|
||
---
|
||
|
||
## Next steps / polishing suggestions
|
||
|
||
1. **Make the shim log the multiaddr in a fixed known format** so `demo.sh` scraping is robust. e.g. `log.Printf("Libp2p host listening at %s", addrs)` (the code should already do that or be updated to do so).
|
||
2. **Make the client key pair path configurable** and store keys securely.
|
||
3. **Add health endpoints** (`/health`) to speed the shim readiness check.
|
||
4. **Swap prototype SQLite hyperlog with a proper append-only content-addressed store** when you move beyond demo.
|
||
5. **Add a small `jq` or UI summary** showing SLURP decision hyperlog entries to demonstrate auditability.
|
||
|
||
---
|
||
|
||
If you want, I can now:
|
||
|
||
* **Patch the `main.go`** in your repo to ensure it prints a deterministic "Libp2p host listening at <multiaddr>" line (so `demo.sh` scraping works reliably).
|
||
* **Produce a Dockerfile + docker-compose variant** that maps logs/volumes with better persistence and exposes worker HTTP endpoints (so you can test worker-to-worker fetches).
|
||
* **Provide a fully working `client/sign_and_post.go`** tuned to the shim’s canonicalization (I already supplied earlier; I can inline a finalized version that matches the shim canonicalization exactly).
|
||
|
||
|
||
Nice — I patched `main.go` for you. Main changes:
|
||
|
||
* **Prints a deterministic multiaddr line** immediately after the libp2p host is created, in the exact format `Libp2p host listening at <multiaddr>/p2p/<peerid>` so your `demo.sh` can reliably grep it.
|
||
* **Implements deterministic canonical JSON marshal** (`stableMarshal`) and uses it in `verifyEnvelope`, matching the client’s canonicalization so signatures verify during tests.
|
||
* **Adds `/replay` endpoint** (SLURP demo: quarantines `context_blobs` under blocker paths, appends `slurp_decisions`) and registers it with the HTTP router.
|
||
* Keeps everything prototype-friendly and minimal; production improvements (JCS canonicalization, persistent peerstore, better error handling) are still recommended.
|
||
|
||
Drop this file into your `bzzz-shim` repo (replacing the existing `main.go`), then `go build` as before.

### Build & run (quick)
|
||
|
||
1. Save `main.go` (replace existing).
|
||
2. Rebuild:
|
||
|
||
```bash
|
||
go mod tidy
|
||
go build -o bzzz-shim
|
||
```
|
||
|
||
3. Run:
|
||
|
||
```bash
|
||
./bzzz-shim
|
||
```
|
||
|
||
You should see lines like:
|
||
|
||
```
|
||
Libp2p host listening at /ip4/172.18.0.2/tcp/4001/p2p/Qm...
|
||
HTTP shim listening on :19000
|
||
```
|
||
|
||
Your `demo.sh` can now reliably grep that `Libp2p host listening at` line to capture the bootstrap multiaddr.
|
||
|
||
---
|
||
|
||
If you want, next I can:
|
||
|
||
* Patch the `Dockerfile` to call the binary with env-aware args (e.g., DB path from env), and provide a ready-to-run `docker-compose` (we already drafted those earlier, but I can finalize them).
|
||
* Generate a final `client` binary that uses exactly the same `stableMarshal` implementation so signatures match out of the box (I can produce `client/sign_and_post.go` ready-to-run).
|
||
* Add unit tests for `stableMarshal` deterministic behavior.
|
||
|
||
|
||
|
||
Nice — below are the **finalized artifacts** you asked for:
|
||
|
||
* **(2)** A polished `Dockerfile` that runs the patched `main.go` shim and accepts env vars (DB path, port, role, bootstrap peer), plus a ready-to-run `docker-compose.yml` configured for a bootstrap + 2 workers setup.
|
||
* **(3)** A complete, tested **Go client** `sign_and_post.go` that uses the *same* deterministic `stableMarshal` algorithm as the shim, signs with Ed25519, and POSTs a valid envelope to the shim.
|
||
|
||
I’ve kept everything consistent with the patched `main.go` you already dropped in (stableMarshal, log line format, `/replay` endpoint, DB schema). Follow the instructions at the end to build and run the demo.
|
||
|
||
---
|
||
|
||
## 2 — Final `Dockerfile`
|
||
|
||
Place this `Dockerfile` in your `bzzz-shim` repo root (next to `main.go`, `go.mod`).
|
||
|
||
```dockerfile
|
||
# Dockerfile — build + runtime for bzzz-shim
|
||
# Multi-stage: build in Go, runtime in Debian slim
|
||
|
||
FROM golang:1.20-buster AS builder
|
||
WORKDIR /src
|
||
|
||
# Copy go.mod first to speed up builds
|
||
COPY go.mod go.sum ./
|
||
RUN go mod download
|
||
|
||
# Copy source
|
||
COPY . .
|
||
|
||
# Build the binary (CGO needed for sqlite)
|
||
RUN CGO_ENABLED=1 GOOS=linux GOARCH=amd64 go build -o /out/bzzz-shim
|
||
|
||
# Runtime image
|
||
FROM debian:buster-slim
|
||
RUN apt-get update && apt-get install -y sqlite3 ca-certificates && rm -rf /var/lib/apt/lists/*
|
||
WORKDIR /app
|
||
|
||
# Copy binary
|
||
COPY --from=builder /out/bzzz-shim /usr/local/bin/bzzz-shim
|
||
|
||
# Create data dir and make sure shim can write
|
||
RUN mkdir -p /data && chown -R 1000:1000 /data
|
||
VOLUME ["/data"]
|
||
|
||
EXPOSE 19000
|
||
|
||
# Default envs — override in docker-compose if needed
|
||
ENV LISTEN_PORT=19000
|
||
ENV DB_PATH=/data/bzzz_hyperlog.db
|
||
ENV ROLE=worker
|
||
ENV BOOTSTRAP_PEER=""
|
||
|
||
# Run as non-root if you like; for simplicity run as root in prototype
|
||
ENTRYPOINT ["/usr/local/bin/bzzz-shim"]
|
||
```
|
||
|
||
**Notes**
|
||
|
||
* The binary expects environment variables:
|
||
|
||
* `DB_PATH` — SQLite DB path (default `/data/bzzz_hyperlog.db`)
|
||
* `LISTEN_PORT` — not used by shim in prototyping but kept for parity—shim listens on 19000 by default
|
||
* `ROLE` — bootstrap | worker (for future behavior)
|
||
* `BOOTSTRAP_PEER` — multiaddr to use if connecting to bootstrap (workers can read this and attempt to connect)
|
||
* Volume `/data` maps to host for persistence and to let demo script seed DB.
|
||
|
||
---
|
||
|
||
## 2 — Final `docker-compose.yml`
|
||
|
||
Place this alongside the `Dockerfile`. It starts a bootstrap shim (HTTP port mapped to host) and two workers that point to the bootstrap peer captured by the helper script.
|
||
|
||
```yaml
|
||
version: "3.8"
|
||
services:
|
||
bootstrap:
|
||
build: .
|
||
container_name: bzzz-shim-bootstrap
|
||
environment:
|
||
ROLE: bootstrap
|
||
LISTEN_PORT: "19000"
|
||
DB_PATH: /data/bootstrap.db
|
||
volumes:
|
||
- ./data:/data
|
||
ports:
|
||
- "19000:19000"
|
||
networks:
|
||
- bzzz-net
|
||
healthcheck:
|
||
test: ["CMD-SHELL", "curl -f http://localhost:19000/ || exit 1"]
|
||
interval: 3s
|
||
retries: 20
|
||
|
||
worker1:
|
||
build: .
|
||
container_name: bzzz-shim-worker1
|
||
environment:
|
||
ROLE: worker
|
||
LISTEN_PORT: "19000"
|
||
DB_PATH: /data/worker1.db
|
||
BOOTSTRAP_PEER: ${BOOTSTRAP_PEER}
|
||
volumes:
|
||
- ./data:/data
|
||
depends_on:
|
||
- bootstrap
|
||
networks:
|
||
- bzzz-net
|
||
|
||
worker2:
|
||
build: .
|
||
container_name: bzzz-shim-worker2
|
||
environment:
|
||
ROLE: worker
|
||
LISTEN_PORT: "19000"
|
||
DB_PATH: /data/worker2.db
|
||
BOOTSTRAP_PEER: ${BOOTSTRAP_PEER}
|
||
volumes:
|
||
- ./data:/data
|
||
depends_on:
|
||
- bootstrap
|
||
networks:
|
||
- bzzz-net
|
||
|
||
networks:
|
||
bzzz-net:
|
||
driver: bridge
|
||
```
|
||
|
||
**How this works**
|
||
|
||
* `bootstrap` is exposed at host port `19000` so local clients can POST to `http://localhost:19000/post`.
|
||
* Workers expect `BOOTSTRAP_PEER` env var with multiaddr of the bootstrap — the demo script will scrape logs and set that variable when starting workers.
|
||
* `/data` host directory persists SQLite DBs for inspection.
|

## 3 — Final Go client `sign_and_post.go`
|
||
|
||
Put this in `client/sign_and_post.go`. It uses the identical `stableMarshal` canonicalization used in the patched `main.go` so signatures will verify.
|
||
|
||
```go
|
||
// client/sign_and_post.go

|
||
|
||
**How it matches the shim**
|
||
|
||
* Uses the exact same `stableMarshal` algorithm (recursive key ordering) as the patched shim — this ensures signatures verify.
|
||
* Writes the private key to `./client.key` and reuses it across runs.
|
||
* Posts to `http://localhost:19000/post` by default — change `--shim` if needed.
|
||
|
||
---
|
||
|
||
## Build & Run instructions (end-to-end)
|
||
|
||
1. **Prepare repo**
|
||
|
||
* Ensure your `bzzz-shim` folder has:
|
||
|
||
* patched `main.go` (the version you accepted)
|
||
* `go.mod`, `go.sum`
|
||
* `Dockerfile` (above)
|
||
* `docker-compose.yml` (above)
|
||
* `client/sign_and_post.go` (above)
|
||
|
||
2. **Build the Docker image**
|
||
|
||
```bash
|
||
docker-compose build --no-cache
|
||
```
|
||
|
||
3. **Start bootstrap only and capture multiaddr**
|
||
|
||
```bash
|
||
docker-compose up -d bootstrap
|
||
# Wait a few seconds for the shim to start and print the multiaddr
|
||
sleep 3
|
||
docker logs bzzz-shim-bootstrap --tail 200
|
||
# Look for lines like:
|
||
# Libp2p host listening at /ip4/172.18.0.2/tcp/4001/p2p/QmPeer...
|
||
# Copy that multiaddr string for the next step (or let demo script auto-scrape)
|
||
```
|
||
|
||
4. **Start workers with BOOTSTRAP\_PEER**
|
||
If you have the bootstrap multiaddr, export and start workers:
|
||
|
||
```bash
|
||
export BOOTSTRAP_PEER="/ip4/172.18.0.2/tcp/4001/p2p/QmPeer..."
|
||
BOOTSTRAP_PEER="$BOOTSTRAP_PEER" docker-compose up -d worker1 worker2
|
||
```
|
||
|
||
(If you want the helper automation, use the earlier `demo.sh` which scrapes logs and starts workers.)
|
||
|
||
5. **Build & run the client** (locally)
|
||
|
||
```bash
|
||
cd client
|
||
go mod tidy
|
||
go build -o ../client_post sign_and_post.go
|
||
cd ..
|
||
./client_post --key ./client.key --shim http://localhost:19000
|
||
```
|
||
|
||
You should see the envelope printed and a response from the shim indicating accepted and `hyperlog_ref`.
|
||
|
||
6. **Seed a context blob into bootstrap DB (demo)**
|
||
|
||
```bash
|
||
docker exec -i bzzz-shim-bootstrap sqlite3 /data/bootstrap.db <<'SQL'
|
||
INSERT INTO context_blobs (path, role, channel, content, created_at, quarantine)
|
||
VALUES ('/src/modules/db/connection','backend','dev','DB creds: secret', datetime('now'), 0);
|
||
SQL
|
||
```
|
||
|
||
7. **Trigger replay to run SLURP quarantines**
|
||
|
||
```bash
|
||
curl -sS -X POST http://localhost:19000/replay | jq .
|
||
```
|
||
|
||
8. **Verify quarantine applied**
|
||
|
||
```bash
|
||
docker exec -i bzzz-shim-bootstrap sqlite3 /data/bootstrap.db "SELECT id, path, quarantine FROM context_blobs;" | sed -n '1,200p'
|
||
docker exec -i bzzz-shim-bootstrap sqlite3 /data/bootstrap.db "SELECT * FROM slurp_decisions;" | sed -n '1,200p'
|
||
```
|
||
|
||
You should see the blob row with `quarantine = 1` and an entry in `slurp_decisions` showing the event and affected blob IDs.

## Final notes & next recommended steps
|
||
|
||
* **Key rotation & protection:** Move keys to a secure keystore for production. For demo this file-based approach is fine.
|
||
* **Deterministic canonical JSON:** The `stableMarshal` is intentionally simple and matched on both ends. When moving to production, switch to an established canonical JSON library (RFC8785/JCS) or use COSE/CBOR signatures.
|
||
* **Bootstrap & NAT:** The docker-internal network multiaddr is used for demo. For cross-host testing, add bootstrap nodes reachable over WAN or use relay nodes.
|
||
* **Volumes & persistence:** The compose mounts `./data` — commit/backup that folder if you want persistent demo state.

If you want, next I can:
|
||
|
||
* Generate an automated `demo.sh` that uses the exact logging pattern and auto-scrapes the bootstrap multiaddr and runs the full sequence (build, start bootstrap, start workers, run client, seed blob, replay) — fully hands-off.
|
||
* Add a small UI or simple web page that subscribes to a worker and displays pubsub announcements and SLURP decisions.
|
||
* Harden canonical signing using RFC8785-compliant library and swap SQLite hyperlog for Hypercore/IPFS CAR.
