Bitflow Hodlmm Zest Yield Loop

Bitflow HODLMM-Zest Yield Loop

What it does

bitflow-hodlmm-zest-yield-loop is a composed controller for the #471 yield-routing path. It coordinates caller-owned sBTC capital between Bitflow HODLMM and Zest by planning route legs, calling accepted primitive skill CLIs, and saving checkpoint state after each confirmed leg.

This is not a primitive deposit, primitive withdrawal, leverage loop, borrow skill, or generic multi-protocol executor. HODLMM write mechanics stay inside bitflow-hodlmm-withdraw, bitflow-hodlmm-deposit, and hodlmm-move-liquidity.

Why agents need it

Agents need a sequencing layer above atomic primitives. A route from HODLMM to Zest or from Zest back to HODLMM may require multiple writes, fresh reads, confirmation between legs, and resume/cancel behavior when a route stops after a partial completion.

Safety notes

• This is a composed write skill and can move funds.
• Mainnet only.
• run and write-capable resume require --confirm=ROUTE.
• Every delegated write leg must also use its primitive-specific confirmation token and return a txid. The controller persists the txid before checking Hiro so interrupted confirmation can be recovered with resume --txid, then marks the leg confirmed only after Hiro verifies tx_status=success.
• It refuses a new route when unresolved checkpoint state exists.
• It shells out to primitive CLIs and only trusts a single JSON object from each primitive.
• It does not import source from other skill directories.
• It composes the accepted HODLMM selected-bin primitives from #551 and #556, as required by the #559 PRD.
• It only treats existing registry surfaces as dependencies when they are named by the PRD and listed in the AIBTC skills directory.
• First-time HODLMM position creation in an existing sBTC pool is valid. A wallet with no prior pool bins must not be rejected when the pool metadata check passes.
• Zest write legs block unless the installed Zest surface reads positions through v0-1-data.get-user-position, converts suppliedShares to asset units for economic checks, and produces a confirmed transaction result that the controller can verify.
• It does not borrow, create leverage, repay, or unwind debt.

Commands

doctor

Checks dependency presence, wallet gas/mempool state, saved checkpoint state, and primitive readiness.

bun run bitflow-hodlmm-zest-yield-loop/bitflow-hodlmm-zest-yield-loop.ts doctor --wallet <stacks-address> --pool-id <pool-id>

status

Reads current route posture without broadcasting.

bun run bitflow-hodlmm-zest-yield-loop/bitflow-hodlmm-zest-yield-loop.ts status --wallet <stacks-address> --source idle --target hodlmm --pool-id <pool-id> --amount-sats <amount>

plan

Builds an ordered route plan by calling primitive read-only previews where available.

bun run bitflow-hodlmm-zest-yield-loop/bitflow-hodlmm-zest-yield-loop.ts plan --wallet <stacks-address> --source idle --target hodlmm --pool-id <pool-id> --amount-sats <amount>

plan includes economicCheck, freshness, and state fields. When comparable HODLMM/Zest route data is unavailable, the controller reports the missing read instead of silently choosing a weaker route.

run

Executes the selected route only after explicit route confirmation. Every delegated write leg must return a txid, and Hiro must verify that txid as tx_status=success before the controller marks the leg confirmed or starts another leg.

bun run bitflow-hodlmm-zest-yield-loop/bitflow-hodlmm-zest-yield-loop.ts run --wallet <stacks-address> --source idle --target hodlmm --pool-id <pool-id> --amount-sats <amount> --confirm=ROUTE

resume

Continues only from supported saved checkpoints after explicit confirmation. If a delegated primitive broadcast succeeded but the controller stopped before checkpoint advancement, pass the confirmed txid so the controller can verify it on Hiro and complete the saved route without rebroadcasting.

bun run bitflow-hodlmm-zest-yield-loop/bitflow-hodlmm-zest-yield-loop.ts resume --wallet <stacks-address> --confirm=ROUTE
bun run bitflow-hodlmm-zest-yield-loop/bitflow-hodlmm-zest-yield-loop.ts resume --wallet <stacks-address> --confirm=ROUTE --txid <confirmed-txid>

cancel

Marks unresolved saved state as operator-cancelled.

bun run bitflow-hodlmm-zest-yield-loop/bitflow-hodlmm-zest-yield-loop.ts cancel --wallet <stacks-address>

Output contract

Every command prints exactly one JSON object to stdout.

{
  "status": "success|blocked|error",
  "action": "doctor|status|plan|run|resume|cancel",
  "data": {},
  "error": null
}

Known constraints

• This controller is the #471 HODLMM-Zest yield router surface, not the #473 leverage stack.
• The differentiation from stacks-alpha-engine is the primitive-only composition contract: this skill sequences HODLMM + Zest primitives with checkpoints, while stacks-alpha-engine is a broader multi-protocol executor and five-stage safety pipeline.
• The dependency list is constrained to the #559 PRD: #551/#556 for accepted HODLMM entry/exit, hodlmm-move-liquidity for HODLMM rebalance, and the existing AIBTC-listed Zest surface for Zest-side reads/writes.
• Cross-venue Zest write routes require the Zest dependency to return canonical position reads and confirmed transaction evidence. If it only returns a handoff, non-broadcast plan, direct suppliedShares value without conversion, or non-canonical market-contract read, this controller blocks instead of claiming execution.
• Borrowing is intentionally outside scope. This skill does not call Zest borrow helpers; any future borrow composition would need a separate PRD update and mainnet-proofed helper version.
• Checkpoints live at the standard AIBTC runtime state path for this skill: ~/.aibtc/state/bitflow-hodlmm-zest-yield-loop/<wallet>.json.
• Resume never blind-retries a write leg. It only advances a saved route from a supplied txid after Hiro confirms tx_status=success and the tx sender matches --wallet.
• Auto-selection is conservative. When the route is ambiguous or comparable EV/freshness data is unavailable, the controller reports hold/blocked route context and requires explicit --source and --target instead of guessing.
• --mempool-depth-limit 0 is intentional: no pending sender transactions are allowed before a route write.
• Mainnet proof belongs in the PR body, not in this generic skill description.
