+# Change: Deploy hfwatch and Register ERC-8004 Identity
+
+## Why
+
+Workstream **A** (Agents, owned by `moises-cisneros` in `agents/*`) is responsible for providing four live/fixture DeFi agents for the pulse marketplace. While the four agent projects run locally and hold keystores in `agents/<agent>/.studio/wallets/`, none are yet deployed to a public HTTPS endpoint or registered on BSC Testnet (chain id 97).
+
+Completing the deployment and on-chain registration of `hfwatch` resolves GitHub [Issue #18](https://github.com/Zer0-Knowledge-Hack/pulse/issues/18) and completes task 4.4 and Section 5 of `scaffold-seed-agents`. This unblocks Stream **S** (evidence generation for the TermiX Agent Advantage track) and provides Stream **C** (Catalog) with authentic `erc8004TokenId` and live endpoints (`/.well-known/agent-card.json` and `/mcp`) to replace temporary Day-0 fixture values.
+
+## What Changes
+
+- Deploy `agents/hfwatch` to a publicly accessible HTTPS host (e.g. Cloudflare Workers / server host) exposing:
+  - `GET https://<host>/.well-known/agent-card.json` (returning the A2A agent card).
+  - `POST/GET https://<host>/mcp` (responding as an MCP endpoint).
+- Run on-chain ERC-8004 identity registration on BSC Testnet (chain id 97) via `agents/scripts/register-erc8004.ts` using the local `hfwatch` keystore (`0x6d07BBc31ea6A9d05B323123470Ae2a7955FfCad`).
+- Extract the resulting `agent_id` (`erc8004TokenId`) and live endpoints formatted per `agents/LISTING-HANDOFF.md`.
+- Post the delivery block to GitHub Issue #18 to complete handoff to Catalog (Stream C) without violating workstream boundaries (Workstream A publishes facts, Catalog updates fixtures).
+
+## Capabilities
+
+### New Capabilities
+None.
+
+### Modified Capabilities
+None (`skip_specs: true` set in `.openspec.yaml` as this change involves operational deployment and on-chain identity minting without altering core spec requirements).
+
+## Impact
+
+- **Owned Path**: `agents/*` only, strictly conforming to `CONTRIBUTING.md` path ownership. No modifications to `apps/web`, `apps/api`, or `packages/indexer/fixtures/`.
+- **Dependencies**: `@bnbagent/studio-cli`, `@bnbagent/sdk`, `viem`.
+- **Rollback Plan**: ERC-8004 registrations on BSC Testnet are immutable identity tokens. If an incorrect endpoint is registered, the on-chain endpoint can be amended using `bag erc8004 update-endpoint --endpoint <url>` without creating duplicate token identities.

+# Change: Deploy and Register Remaining Seed Agents (Rangekeeper, Yieldrouter, Gridrunner)
+
+## Why
+
+The BNB Agent Studio Hackathon ("Smart Money Era") evaluation rubric explicitly mandates:
+> *"Four categories, all first-class... Single-category submissions score poorly. All four, equally deep, is the bar."*
+> *"Agent Diversity: All four categories surfaced with equal depth. Agents surfaced on your marketplace must be live on BSC."*
+
+Following the successful public deployment and ERC-8004 identity registration of `hfwatch` (`health_factor`, token ID `2292`), the remaining three seed agents (`rangekeeper`, `yieldrouter`, and `gridrunner`) must also be deployed to public HTTPS edge endpoints and registered on BSC Testnet (chain id 97).
+
+This fulfills task 71 of the sprint plan (`docs/sprint.md`: *"Stretch: Three more agents live on testnet (A)"*) and equips Stream C (Catalog) with real, honest on-chain token IDs and live endpoints across all four marketplace categories.
+
+## What Changes
+
+1. **Rangekeeper (`rebalancing`)**:
+   - Deploy `rangekeeper-agent` Cloudflare Worker (`agents/rangekeeper/worker.ts`, `agents/rangekeeper/wrangler.toml`).
+   - Probe `/.well-known/agent-card.json` and `/mcp`.
+   - Register ERC-8004 identity on BSC Testnet for wallet `0xCC2abE29F43EAb530a6b5D93E3C41bc0E7622b47`.
+2. **Yieldrouter (`yield`)**:
+   - Deploy `yieldrouter-agent` Cloudflare Worker (`agents/yieldrouter/worker.ts`, `agents/yieldrouter/wrangler.toml`).
+   - Probe `/.well-known/agent-card.json` and `/mcp`.
+   - Register ERC-8004 identity on BSC Testnet for wallet `0xe1D07be03DDE2C292f842AdE4f34782FDf9176c5`.
+3. **Gridrunner (`grid_trading`)**:
+   - Deploy `gridrunner-agent` Cloudflare Worker (`agents/gridrunner/worker.ts`, `agents/gridrunner/wrangler.toml`).
+   - Probe `/.well-known/agent-card.json` and `/mcp`.
+   - Register ERC-8004 identity on BSC Testnet for wallet `0x78f800FBA857Ae0a33eEa55f62a68ddA20b27185`.
+4. **Catalog Delivery & Context Ledger**:
+   - Format listing facts for all four categories per `agents/LISTING-HANDOFF.md`.
+   - Synchronize `agents/CONTEXT.md` and `.antigravity/CONTEXT.md`.

+- **Rollback Plan**: On-chain registrations mint immutable ERC-8004 tokens. If endpoints change in the future, endpoints can be updated using `bag erc8004 update-endpoint --endpoint <url>` without minting duplicate identities.
