What every assertion proves — by phase + +The Tenderly run is meaningful **only** because of the assertions inside each +task. Below is every check, what it proves, and what production behavior it +certifies. + +### Phase 0 — `tenderly:snapshot` + +Captures live state and writes `tenderly-snapshot.json`. + +| Read / assertion | What it proves | +| ------------------------------------------------------------------------------- | ----------------------------------------------------------------------------------------------- | +| `ProxyAdmin.getProxyImplementation(maticX)` → `liveImpl` | Anchor for Phase 1 to confirm the upgrade actually swapped the impl. | +| `totalSupply()`, `polBalance`, `maticBalance` | Diff vs. Phase 1 verify proves the upgrade preserves legacy state. | +| Per-validator `getTotalStake(maticX)` + sum | Phase 2 uses this to assert every validator with prior stake gets `DrainUnbondInitiated`. | +| **`sum(per-validator stakes) == getTotalStakeAcrossAllValidators()`** | Confirms the live state isn't already drifted at snapshot time — accounting sanity baseline. | +| `treasury`, `balanceOf(treasury)`, `feePercent` | Phase 1 verify diffs these to prove the upgrade doesn't silently mutate fee config or treasury. | + +### Phase 1 — `tenderly:upgrade` + +Deploys new impl (direct, bypassing OZ manifest because `forceImport` would +mis-register), executes the upgrade via `ProxyAdmin.owner()` or a passed +Timelock, then verifies state. + +| Assertion | What it proves | +| ---------------------------------------------------------------------------------------------------------- | --------------------------------------------------------------------------------------------------------------- | +| `proxyAdmin.getProxyImplementation(maticX) == newImpl` | The upgrade actually swapped the implementation slot. | +| `drainComplete`, `instantRedeemEnabled`, `drainedPolBalance`, `frozenRate`, `drainCompleteTimestamp` all 0 | New sunset storage slots default to zero — no constructor-side-effect that would put the contract mid-flow. | +| `totalSupply` matches snapshot | Upgrade didn't mint or burn. | +| `treasury` matches snapshot | Storage layout collision check — would surface as a corrupted `treasury` address. | +| `feePercent` matches snapshot | Same. | +| `balanceOf(treasury)` matches snapshot | ERC20 balances are untouched by the upgrade. | + +### Phase 1.5 — `tenderly:pre-sunset-request` + +Holder calls `requestWithdraw(1% of balance)` while the contract is still +active. This sets up Phase 3.5. + +| Assertion | What it proves | +| --------------------------------------------------------------- | ------------------------------------------------------------------------------------------- | +| `paused() == false` precondition | requestWithdraw is `whenNotPaused`; this must succeed before sunset starts. | +| Calldata matches `requestWithdraw(amount)` encoding | Byte-equality with `sunset:encode-step` — rehearsal calldata = production Safe calldata. | +| `getUserWithdrawalRequests(holder).length` grew by 1 | Withdrawal queue actually appended a new request at the persisted index. | + +### Phase 2 — `tenderly:run-sunset` + +The full sunset operational sequence. Every step asserts (a) state, (b) +event emission with expected args, (c) byte-equality vs `sunset:encode-step`. +Idempotent: if `drainComplete` is already true, skips 2b–2e and resumes at +2f. If `instantRedeemEnabled` is already true, skips 2g. + +| Step | Call | Assertion(s) | What it proves | +| :--: | :--- | :--------------------------------------------------------------------------------------------------- | :------------------------------------------------------------------------------------------------------------------- | +| 2a | `togglePause()` | `paused() == true`; calldata match | The exact production-Safe calldata pauses the contract on real state. | +| 2b | `bulkUnstakeAllValidators()` | `DrainUnbondInitiated` event count == # validators with prior stake; every `getTotalStake(maticX) == 0`; `drainUnbondNonces[vs]` has entries; calldata match | The drain initiates one unbond per validator. No validator is skipped silently. Nonces are recorded for claim phase. | +| 2c | `setCurrentEpoch(epoch + delay + 1)` (impersonated `stakeManagerGovernance`) | `epoch()` advanced past `withdrawalDelay` | The unbond period is correctly simulated. Real mainnet would require waiting ~21 days. | +| 2d | `claimDrainNonces()` | `polBalance(maticX)` strictly grew; every `drainUnbondNonces[vs]` empty; `maticBalance(maticX) == 0`; calldata match | All recorded nonces are claimed. No silent leftover. The contract no longer holds legacy MATIC dust pre-freeze. | +| 2e | `freezeExchangeRate()` | `drainComplete == true`; `drainedPolBalance == polAfter`; `frozenRate == polAfter * 1e18 / supplyAtFreeze`; `DrainCompleted(polAfter, supply, rate)` event; calldata match | The one-way freeze captures POL balance and computes rate correctly. `drift = 0` (snapshot integrity). | +| 2e | `assertDrift("post-freeze")` | `polBalance(maticX) − drainedPolBalance == 0` | **Phase 9 gate**: the drained pool matches POL the contract actually holds. | +| 2f | `pushFrozenRateToL2()` | `FrozenRatePushedToL2(supply, drainedPolBalance)` event with current values; calldata match | The L2 side will receive correct ratio. Opt-out via `TENDERLY_SKIP_PUSH_L2=1`. | +| 2g | `setInstantRedeemEnabled(true)` | `instantRedeemEnabled == true`; `InstantRedeemToggled(manager, true)` event; calldata match | Production-side kill-switch is the same address that runs every other admin step. | + +### Phase 3.5 — `tenderly:pre-sunset-claim` + +The same holder from 1.5 claims their pre-sunset withdrawal **during** +the paused sunset window. + +| Assertion | What it proves | +| ---------------------------------------------------------------------------------- | -------------------------------------------------------------------------------------------------------------------- | +| `paused() == true` precondition | We're really in the sunset window. | +| Calldata matches `claimWithdrawal(idx)` encoding | Byte-equality with `sunset:encode-step`. | +| Holder POL balance strictly increased | The legacy unbond path actually pays out. The branch's removal of `whenNotPaused` on `claimWithdrawal` is correct. | +| **`drainedPolBalance` unchanged before vs. after** | The legacy claim path is fully independent of the drained pool. This is the load-bearing invariant for `instantClaim` accounting — if it ever broke, every `instantClaim` on the production contract would be subject to drift. | + +### Phase 3 — `tenderly:user-claim` + +A real MATICx holder (auto-discovered or passed via `--holder`) calls +`instantClaim`. Default `--mode full` burns the entire balance in one tx +to conserve Tenderly free-tier quota. + +| Assertion (per claim) | What it proves | +| ------------------------------------------------------------------ | --------------------------------------------------------------------------------------------- | +| Calldata matches `instantClaim(amount)` encoding | Byte-equality. | +| `InstantClaimed(holder, amount, expectedPol)` event | The contract emits the right tuple. | +| Holder shares `before − amount` | Burn happened. | +| `drainedPolBalance` decremented by `expectedPol = amount * frozenRate / 1e18` | Internal accounting decrements 1:1 with payout. Future claims cannot over-promise. | +| Holder POL gained == `expectedPol` | The user actually receives the right amount. | +| `assertDrift("post-")` | `polBalance == drainedPolBalance` invariant holds across every claim — Phase 9 gate. | +| (mode=all only) After full-redeem: `balanceOf(holder) == 0` | Full accounting closure: every share the holder had maps to POL paid out. | + +### Phase 4 — `tenderly:sweep` + +3-year `evm_increaseTime` and `sweepToCustody`. Long-tail handover after +the immediate sunset window has closed. + +| Assertion | What it proves | +| ----------------------------------------------------------------------- | ----------------------------------------------------------------------------------------------- | +| `CUSTODY_DELAY` actually enforced | The contract's `block.timestamp < drainCompleteTimestamp + CUSTODY_DELAY` revert is real. | +| Calldata matches `sweepToCustody(custody)` encoding | Byte-equality. | +| `SweptToCustody(custody, polAmount, maticAmount)` event with exact args | Event emission for off-chain monitoring. | +| Proxy POL and MATIC balances both 0 | Nothing left behind. | +| `drainedPolBalance == 0` post-sweep | Accounting reset to terminal state. | +| Custody received both balances | The funds actually moved to the intended address. | +| `assertDrift("post-sweep")` | Final drift invariant — Phase 9 gate. | + +### Phase 7 — `tenderly:edge-cases` (Tenderly subset) + +Most negative paths live in `test/Sunset.ts` (no quota cost). The Tenderly +edge-cases task runs a small subset for visibility on real state: + +- `bulkUnstakeAllValidators` without pause → `"Pause first"` +- Random EOA against an admin function → `AccessControl: …` +- `pushFrozenRateToL2` before freeze → `DrainNotComplete` +- `setInstantRedeemEnabled(true)` before freeze → `DrainNotComplete` +- `sweepToCustody` before freeze → `DrainNotComplete` +- `instantClaim` while disabled → `InstantRedeemNotEnabled` +- (in `run-sunset`, opt-in) freeze-twice → `DrainAlreadyComplete` + +Custom-error reverts are resolved by selector lookup against the MaticX +interface so ethers-v6's "unknown custom error" message format doesn't +break assertions. + +--- + +## 4. Byte-equality guarantee — what it actually does + +Every state-changing admin call in the Tenderly tasks runs +`assertCalldata(hre, tx, methodName, args, label)` after submission. + +`assertCalldata` re-encodes `(method, args)` via the shared +`MATIC_X_ADMIN_IFACE_FRAGMENTS` constant and compares against the +actual `tx.data` the rehearsal submitted. Since `tasks/sunset.ts` (the +production calldata-encoder for the Safe) uses the same fragments, +the **calldata my Tenderly tasks submit is byte-identical to what +`sunset:encode-step --step ` emits**. + +So the production Safe will execute the exact same bytes that the rehearsal +already proved correct on real mainnet validator state.

How these tests make the plan solid + +The Phase 9 acceptance gate in the original plan asked four things. Here is +how each is now met: + +| Gate | Status | Mechanism | +| --------------------------------------------------------------------------------------------- | :---------: | ------------------------------------------------------------------------------------------------------------------------ | +| Phases 1–4 green on Tenderly against latest mainnet block | ✓ | `tenderly:all` runs end-to-end with 17 named assertions across the 4 phases against current Polygon validator state. | +| All 10 edge cases produce the expected revert | ✓ (split) | 6 on Tenderly (real-state visibility), 10 in `test/Sunset.ts` (no quota cost, full revert-message matrix). | +| `drift = polBalance − drainedPolBalance == 0` after freeze and after sweep | ✓ | `assertDrift` is called after freeze, after every `instantClaim`, and after sweep. Both gate checkpoints are explicit. | +| Calldata used in Tenderly is byte-equal to what the production Safe will receive | ✓ | Every admin tx calls `assertCalldata` against the same `MATIC_X_ADMIN_IFACE_FRAGMENTS` that `tasks/sunset.ts` uses for encoding. Rehearsal ≡ production. | + +What this delivers in practical terms: + +1. **Storage layout safe** — Phase 1 verify diffs `totalSupply`, `treasury`, `feePercent`, and treasury balance against the pre-upgrade snapshot. If the new impl had a slot collision, these would fail. +2. **No mid-flow regressions** — Phase 1 verify also asserts every new sunset slot is zero/false. Combined with the legacy diff, this catches both "new slot collides with old" and "constructor accidentally sets a flag". +3. **Drain completeness** — Phase 2 asserts that bulk-unstake initiated one unbond per validator that had stake (no skipped validator), and that claim-drain fully empties every `drainUnbondNonces[vs]` array. No POL is left undrained. +4. **Math correctness** — `frozenRate == drainedPolBalance × 1e18 / totalSupply` is verified at the freeze block. Every subsequent `instantClaim` is asserted to pay exactly `amount × frozenRate / 1e18` and decrement `drainedPolBalance` by the same amount. +5. **The two paths don't interfere** — Phase 3.5 proves that a pre-sunset `requestWithdraw` can be claimed during sunset without touching `drainedPolBalance`. This is the load-bearing invariant: the contract has two POL-payout paths (legacy `claimWithdrawal` and new `instantClaim`), and they share the proxy's POL balance but not the drained-pool accounting. If they did interfere, `instantClaim` could over- or under-pay later users. +6. **Production calldata is rehearsed bit-for-bit** — every Tenderly tx asserts byte-equality with the production-Safe encoding. The Safe will execute identical bytes; nothing is generated differently between rehearsal and production. +7. **Idempotent resume** — `tenderly:run-sunset` can be re-run on a partially-progressed TestNet without burning ops on already-done irreversible steps. Useful for free-tier work AND for the real runbook (after the multisig executes step N, anyone can re-read `sunset:status` and pick up at step N+1 without coordination overhead). + +The Tenderly run is the **process** rehearsal. The local suite is the +**exhaustive** rigor. Both must be green before any production calldata +is signed. + +--- + +## 8.

This sets up Phase 3.5. - -| Assertion | What it proves | -| --------------------------------------------------------------- | ------------------------------------------------------------------------------------------- | -| `paused() == false` precondition | requestWithdraw is `whenNotPaused`; this must succeed before sunset starts. | -| Calldata matches `requestWithdraw(amount)` encoding | Byte-equality with `sunset:encode-step` — rehearsal calldata = production Safe calldata. | -| `getUserWithdrawalRequests(holder).length` grew by 1 | Withdrawal queue actually appended a new request at the persisted index. | - -### Phase 2 — `tenderly:run-sunset` - -The full sunset operational sequence. Every step asserts (a) state, (b) -event emission with expected args, (c) byte-equality vs `sunset:encode-step`. -Idempotent: if `drainComplete` is already true, skips 2b–2e and resumes at -2f.

No validator is skipped silently. Nonces are recorded for claim phase. | -| 2c | `setCurrentEpoch(epoch + delay + 1)` (impersonated `stakeManagerGovernance`) | `epoch()` advanced past `withdrawalDelay` | The unbond period is correctly simulated. Real mainnet would require waiting ~21 days. | -| 2d | `claimDrainNonces()` | `polBalance(maticX)` strictly grew; every `drainUnbondNonces[vs]` empty; `maticBalance(maticX) == 0`; calldata match | All recorded nonces are claimed. No silent leftover. The contract no longer holds legacy MATIC dust pre-freeze. | -| 2e | `freezeExchangeRate()` | `drainComplete == true`; `drainedPolBalance == polAfter`; `frozenRate == polAfter * 1e18 / supplyAtFreeze`; `DrainCompleted(polAfter, supply, rate)` event; calldata match | The one-way freeze captures POL balance and computes rate correctly. `drift = 0` (snapshot integrity). | -| 2e | `assertDrift("post-freeze")` | `polBalance(maticX) − drainedPolBalance == 0` | **Phase 9 gate**: the drained pool matches POL the contract actually holds. | -| 2f | `pushFrozenRateToL2()` | `FrozenRatePushedToL2(supply, drainedPolBalance)` event with current values; calldata match | The L2 side will receive correct ratio. Opt-out via `TENDERLY_SKIP_PUSH_L2=1`. | -| 2g | `setInstantRedeemEnabled(true)` | `instantRedeemEnabled == true`; `InstantRedeemToggled(manager, true)` event; calldata match | Production-side kill-switch is the same address that runs every other admin step. | - -### Phase 3.5 — `tenderly:pre-sunset-claim` - -The same holder from 1.5 claims their pre-sunset withdrawal **during** -the paused sunset window. - -| Assertion | What it proves | -| ---------------------------------------------------------------------------------- | -------------------------------------------------------------------------------------------------------------------- | -| `paused() == true` precondition | We're really in the sunset window. | -| Calldata matches `claimWithdrawal(idx)` encoding | Byte-equality with `sunset:encode-step`. | -| Holder POL balance strictly increased | The legacy unbond path actually pays out.

This is the load-bearing invariant for `instantClaim` accounting — if it ever broke, every `instantClaim` on the production contract would be subject to drift. | - -### Phase 3 — `tenderly:user-claim` - -A real MATICx holder (auto-discovered or passed via `--holder`) calls -`instantClaim`.

Future claims cannot over-promise. | -| Holder POL gained == `expectedPol` | The user actually receives the right amount. | -| `assertDrift("post-")` | `polBalance == drainedPolBalance` invariant holds across every claim — Phase 9 gate. | -| (mode=all only) After full-redeem: `balanceOf(holder) == 0` | Full accounting closure: every share the holder had maps to POL paid out. | - -### Phase 4 — `tenderly:sweep` - -3-year `evm_increaseTime` and `sweepToCustody`. Long-tail handover after -the immediate sunset window has closed. - -| Assertion | What it proves | -| ----------------------------------------------------------------------- | ----------------------------------------------------------------------------------------------- | -| `CUSTODY_DELAY` actually enforced | The contract's `block.timestamp < drainCompleteTimestamp + CUSTODY_DELAY` revert is real. | -| Calldata matches `sweepToCustody(custody)` encoding | Byte-equality. | -| `SweptToCustody(custody, polAmount, maticAmount)` event with exact args | Event emission for off-chain monitoring. | -| Proxy POL and MATIC balances both 0 | Nothing left behind. | -| `drainedPolBalance == 0` post-sweep | Accounting reset to terminal state. | -| Custody received both balances | The funds actually moved to the intended address. | -| `assertDrift("post-sweep")` | Final drift invariant — Phase 9 gate. | - -### Phase 7 — `tenderly:edge-cases` (Tenderly subset) - -Most negative paths live in `test/Sunset.ts` (no quota cost). The Tenderly -edge-cases task runs a small subset for visibility on real state: - -- `bulkUnstakeAllValidators` without pause → `"Pause first"` -- Random EOA against an admin function → `AccessControl: …` -- `pushFrozenRateToL2` before freeze → `DrainNotComplete` -- `setInstantRedeemEnabled(true)` before freeze → `DrainNotComplete` -- `sweepToCustody` before freeze → `DrainNotComplete` -- `instantClaim` while disabled → `InstantRedeemNotEnabled` -- (in `run-sunset`, opt-in) freeze-twice → `DrainAlreadyComplete` - -Custom-error reverts are resolved by selector lookup against the MaticX -interface so ethers-v6's "unknown custom error" message format doesn't -break assertions. - ---- - -## 4. Byte-equality guarantee — what it actually does - -Every state-changing admin call in the Tenderly tasks runs -`assertCalldata(hre, tx, methodName, args, label)` after submission. - -`assertCalldata` re-encodes `(method, args)` via the shared -`MATIC_X_ADMIN_IFACE_FRAGMENTS` constant and compares against the -actual `tx.data` the rehearsal submitted. Since `tasks/sunset.ts` (the -production calldata-encoder for the Safe) uses the same fragments, -the **calldata my Tenderly tasks submit is byte-identical to what -`sunset:encode-step --step ` emits**. - -So the production Safe will execute the exact same bytes that the rehearsal -already proved correct on real mainnet validator state.

What's covered locally only (`test/Sunset.ts`) - -Tenderly's quota forces a focused rehearsal. The exhaustive coverage lives -in `test/Sunset.ts` against a local hardhat fork (no quota).

How these tests make the plan solid - -The Phase 9 acceptance gate in the original plan asked four things. Here is -how each is now met: - -| Gate | Status | Mechanism | -| --------------------------------------------------------------------------------------------- | :---------: | ------------------------------------------------------------------------------------------------------------------------ | -| Phases 1–4 green on Tenderly against latest mainnet block | ✓ | `tenderly:all` runs end-to-end with 17 named assertions across the 4 phases against current Polygon validator state. | -| All 10 edge cases produce the expected revert | ✓ (split) | 6 on Tenderly (real-state visibility), 10 in `test/Sunset.ts` (no quota cost, full revert-message matrix). | -| `drift = polBalance − drainedPolBalance == 0` after freeze and after sweep | ✓ | `assertDrift` is called after freeze, after every `instantClaim`, and after sweep. Both gate checkpoints are explicit. | -| Calldata used in Tenderly is byte-equal to what the production Safe will receive | ✓ | Every admin tx calls `assertCalldata` against the same `MATIC_X_ADMIN_IFACE_FRAGMENTS` that `tasks/sunset.ts` uses for encoding. Rehearsal ≡ production. | - -What this delivers in practical terms: - -1. **Storage layout safe** — Phase 1 verify diffs `totalSupply`, `treasury`, `feePercent`, and treasury balance against the pre-upgrade snapshot. If the new impl had a slot collision, these would fail. -2. **No mid-flow regressions** — Phase 1 verify also asserts every new sunset slot is zero/false. Combined with the legacy diff, this catches both "new slot collides with old" and "constructor accidentally sets a flag". -3. **Drain completeness** — Phase 2 asserts that bulk-unstake initiated one unbond per validator that had stake (no skipped validator), and that claim-drain fully empties every `drainUnbondNonces[vs]` array. No POL is left undrained. -4. **Math correctness** — `frozenRate == drainedPolBalance × 1e18 / totalSupply` is verified at the freeze block. Every subsequent `instantClaim` is asserted to pay exactly `amount × frozenRate / 1e18` and decrement `drainedPolBalance` by the same amount. -5. **The two paths don't interfere** — Phase 3.5 proves that a pre-sunset `requestWithdraw` can be claimed during sunset without touching `drainedPolBalance`. This is the load-bearing invariant: the contract has two POL-payout paths (legacy `claimWithdrawal` and new `instantClaim`), and they share the proxy's POL balance but not the drained-pool accounting. If they did interfere, `instantClaim` could over- or under-pay later users. -6. **Production calldata is rehearsed bit-for-bit** — every Tenderly tx asserts byte-equality with the production-Safe encoding. The Safe will execute identical bytes; nothing is generated differently between rehearsal and production. -7. **Idempotent resume** — `tenderly:run-sunset` can be re-run on a partially-progressed TestNet without burning ops on already-done irreversible steps. Useful for free-tier work AND for the real runbook (after the multisig executes step N, anyone can re-read `sunset:status` and pick up at step N+1 without coordination overhead). - -The Tenderly run is the **process** rehearsal. The local suite is the -**exhaustive** rigor. Both must be green before any production calldata -is signed. - ---- - -## 8.

"Terminal rate" is clearer than "frozen rate" for non-technical consumers (lending markets, integrators).

Add a three-stage state machine: recallInitiated <- set on first bulkUnstakeAllValidators (now once-only; reverts on re-entry) recallClaimsComplete <- set after claimAssetRecallNonces loop finishes; any per-validator revert (unbond not matured) rolls back the flag so the txn can be retried terminalRateLocked <- set inside finalizeTerminalRate, gated on recallClaimsComplete finalizeTerminalRate now reverts with RecallClaimsNotComplete if any unbond is still pending. claimAssetRecallNonces reverts with RecallNotInitiated if called before bulkUnstake, preventing the flag from being set prematurely with zero work done. Rename for clarity, since 'assetRecallComplete' semantically marked the *finalize* step rather than the recall itself (recall completes at claim, the rate is what's locked at finalize): assetRecallComplete -> terminalRateLocked assetRecallTimestamp -> terminalRateLockTimestamp AssetRecallAlreadyComplete -> TerminalRateAlreadyLocked AssetRecallNotComplete -> TerminalRateNotLocked Tests and operational tasks updated to match. Event names left unchanged (AssetRecallInitiated / AssetRecallCompleted describe lifecycle phases, not flag state).
