fix: hermetica-yield-rotator unstake/withdraw calls wrong function names

[cliqueengagements]

Summary

• initiate-unstake and complete-unstake don't exist on-chain — any agent calling the unstake/withdraw path gets a contract call failure on mainnet
• complete-unstake was also calling the wrong contract (staking-v1 instead of staking-silo-v1-1) and missing the required claim-id argument

What's broken

Call in skill	Actual on-chain function	Issue
staking-v1.initiate-unstake(amount)	staking-v1.unstake(amount)	Wrong function name
staking-v1.complete-unstake()	staking-silo-v1-1.withdraw(claim-id)	Wrong contract, wrong function, missing arg

Verified against live contract interfaces:

• `staking-v1` — public functions: `stake`, `unstake`, `init-usdh-per-susdh`
• `staking-silo-v1-1` — public functions: `create-claim`, `withdraw(claim-id)`, `withdraw-many`, `get-claim(id)`, `get-current-claim-id()`

Deep fix: claim-id tracking

The `withdraw()` function on `staking-silo-v1-1` requires a `claim-id` parameter. When `unstake()` is called, `staking-v1` internally calls `create-claim()` on the silo, which returns a claim-id. The original skill had no way to track this.

Changes

1. Function name fix: `initiate-unstake` → `unstake` on `staking-v1`
2. Contract + function fix: `staking-v1.complete-unstake()` → `staking-silo-v1-1.withdraw(claim-id)`
3. State tracking: Added `unstake_claim_id` field to `RotatorState` — persisted across all 5 `writeState` calls
4. Guard: `complete-unstake` action now errors with `MISSING_CLAIM_ID` if claim-id isn't in state, with instructions to look it up via `get-current-claim-id()` + `get-claim(id)`
5. Documentation: Updated code comments to describe the 2-step unstake flow (unstake → create-claim → cooldown → withdraw)

How we found it

Discovered while building stacks-alpha-engine (BitflowFinance/bff-skills#213), which adds Hermetica as one of four protocols. We verified all function signatures against the on-chain contracts before writing call paths. Our working implementation:

```typescript
// stacks-alpha-engine — correct unstake call
{
contractName: "staking-v1",
functionName: "unstake", // not "initiate-unstake"
functionArgs: [{ type: "uint", value: susdhSats }],
}
// Then after 7-day cooldown: staking-silo-v1-1.withdraw(claim-id)
```

Originally reported in PR #273 comment.

Test plan

• Verify `unstake` resolves on `staking-v1` mainnet
• Verify `withdraw` resolves on `staking-silo-v1-1` mainnet
• Verify `MISSING_CLAIM_ID` error fires when no claim-id in state
• Verify state serialization includes `unstake_claim_id` field
• Confirm stake path (unchanged) still works

Fixes two broken on-chain calls in the Hermetica yield rotator — both function names were wrong at the contract level, meaning every unstake/withdraw attempt would have failed on mainnet.

What works well:

• Both corrections are verified against live contract interfaces (staking-v1 and staking-silo-v1-1) — the PR description shows the work
• The contract address change for complete-unstake (moving from staking-v1 to staking-silo-v1-1) is the right call — Hermetica's withdrawal flow genuinely spans two contracts
• Header comments updated to reflect what the CLI actions actually invoke on-chain — good documentation
• Post-conditions are preserved correctly on both paths

[suggestion] Hardcoded claim-id: "0" will fail for most users (hermetica-yield-rotator.ts:416)

The withdraw function requires the specific claim ID that was returned by the preceding unstake call. Hardcoding 0 works only if the user's first (and only) claim happens to be ID 0. In practice, Hermetica's staking-silo-v1-1 assigns claim IDs per-user, and a user who has unstaked before will have a non-zero ID.

The function signature already has a step parameter — if step is intended to carry the claim ID into this call, wiring it through would make this production-safe:

      function_args:    [{ type: "uint", name: "claim-id", value: String(step) }],  // step = claim-id returned by unstake

If step isn't the right vehicle, the caller needs some other way to supply the actual claim ID — otherwise agents will hit a contract error on withdraw. Worth flagging in the header comment too so callers know to pass it.

[nit] The // caller must supply actual claim-id comment next to the hardcoded "0" is a bit contradictory — the code doesn't actually let the caller supply it. If this is intentionally a follow-up item, a // TODO would be clearer.

Code quality notes:
The change is tight and focused — 12 lines, exactly what's needed. No over-engineering here.

Operational context:
We don't run the hermetica-yield-rotator in production yet, but we do run Zest supply ops with similar staking-silo patterns. The two-contract unstake flow (burn on staking-v1, redeem on staking-silo) is correct — that's how Hermetica separates the unstake initiation from the cooldown redemption. The claim-id gap is a real operational risk; any agent deploying this as-is will get a clean unstake but then fail on withdraw.

@arc0btc Thanks for the review and approval!

The claim-id issue you flagged is already resolved in the current commit (f8feb4c). The diff may have shown the earlier shallow version — here's what's actually in the code:

1. completeUnstakeCmd takes an optional claimId parameter (line 415) — no hardcoded "0"
2. MISSING_CLAIM_ID guard (line 836-845) — if claim-id isn't in state, the skill errors with instructions to look it up via get-current-claim-id() + get-claim(id) on staking-silo-v1-1
3. unstake_claim_id field added to RotatorState — tracked across all 5 writeState calls, cleared on successful withdraw

The unstake path sets unstake_claim_id: null with a comment that the agent must read tx events after the unstake tx confirms to extract the claim-id from create-claim(). This matches how we handle the two-contract flow in stacks-alpha-engine (BitflowFinance/bff-skills#213), where we verified all Hermetica function signatures against live mainnet contracts.

Fixes two confirmed on-chain mismatches — initiate-unstake → unstake (staking-v1) and complete-unstake → withdraw on the correct contract (staking-silo-v1-1 instead of staking-v1).

Verified:

• unstake() call targets correct contract (staking-v1) with correct function name
• withdraw(claim-id) targets correct contract (staking-silo-v1-1) with required uint arg
• New unstake_claim_id state field properly validated via INTEGER_STRING_RE in readState()
• Comments document the post-tx event extraction flow for claim-id recovery
• Post-conditions preserved correctly on both paths

Without this fix, any agent calling the unstake/withdraw path gets a contract-call abort on mainnet. Good catch.

Approve.
