## MR description (from the author, untrusted)

```markdown
Swap, liquidity, refund, and vault transitions can violate financial obligations even when each individual output looks valid. This change adds seeded property campaigns under a new `AccountingPropertySuite` in `x/thorchain`. Each campaign checks pool, Reserve, pending, paid, and vault balances against an independent accounting oracle.

The campaigns cover:
- **Pool flow:** random add, split-arrival, and withdraw sequences, ending with a full 10,000-bps withdrawal that checks the basis-point cap and gas kept in the pool. An add with a mismatched asset address must be rejected without changing state. A withdrawal that rounds to zero may be rejected only if state is untouched. The campaign fails on any add rejection other than dust that rounds to zero LP units. It also fails if the run never did an add, a split completion, and a withdrawal, so a handler that rejects every deposit cannot pass.
- **Swap flow:** swaps in both directions and three-part sub-swap sequences, checking that pool balances plus the RUNE fee sent to Reserve are conserved and that LP units do not change. The sub-swaps call the swapper directly, so they cover pool arithmetic and streaming event counters only. A swap to the same asset must be rejected with no pool, event, or outbound change.
- **Persisted streaming swap:** a V2 RUNE→ETH stream driven block by block through the advanced swap queue. Each block, the stored `State.In`/`State.Out` must match the pool and Reserve deltas. There must be no early outbound, exactly one final outbound of the released asset to the destination, and no repeat payout after the stream completes.
- **Pending liquidity refund:** a staged deposit is a refundable liability, and repeating the withdrawal must not pay it twice.
- **Native deposit pending conservation:** a native RUNE `ADD` moves exactly the deposit from the account to Asgard and records it as pending on both the pool and the LP. A deposit with a bad memo must leave balances, pool, LP, and events unchanged.
- **Vault funds transfer persistence:** coins debited from a retiring Asgard record and credited to an active one keep the same total after a keeper round-trip, and the pool stays unchanged. This checks bookkeeping only; it does not schedule or observe a migrate outbound.
- **Refund outbound obligation:** a refund creates one bounded outbound across the whole `TxOutDelayMax` scheduling window. Retrying the same inbound must not create a second liability, and the vault's coin stays put until the outbound is observed.
- **Seed 15 regression:** a 1-bps withdrawal of 664 units that rounds to zero must be rejected without changing state.
- **Oracle self-check:** a one-unit change to any ledger term must be detected.

Seeds come from `THORNODE_ACCOUNTING_SEED` (a single seed) or `THORNODE_ACCOUNTING_SEEDS` (1–256). The default is four seeds, one of which is seed 15. `scripts/test-accounting-property.sh` runs a `fast` (4 seeds) or `campaign` (32 seeds) pass. A new scheduled-only `accounting-properties-deep` CI job runs the campaign pass and keeps its log as an artifact.

Validation: The four-seed fast and 32-seed campaign runs passed locally; the integrated root unit job passed. This topic is also included in draft !5181. This MR will run its own CI against `develop`; review and merge coordination should avoid landing the same change twice.
```

## What changed (AI summary)

- **Ledger oracle**: pool + pending + paid + Reserve fee = in; ±1 unit breaks it.
- **Pool flow**: 24 seeded add / stage / withdraw steps; only dust rejections tolerated.
- **Swap flow**: Pool + Reserve fee conserved both ways; LP units fixed.
- **Persisted stream**: V2 stream via the advanced queue; State.In/Out reconciled each block.
- **Pending liabilities**: Staged deposit refunds once; native ADD lands as pending.
- **Refund obligation**: One bounded outbound across the whole TxOutDelayMax window.
- **Vault transfer**: Retiring + active Asgard total survives keeper round-trips.
- **Seeds + CI**: Seeds 1,2,3,15 by default; 32-seed scheduled deep job.

## Review flags (AI, verify them)

- [verify] scripts/test-accounting-property.sh:20 Deep run lacks mocknet tag and -run filter: No -tags=mocknet: the deep job uses mainnet constants (EnableAdvSwapQueue 0), unlike unit-tests, and runs the package's other top-level tests.
- [careful] x/thorchain/handler_accounting_property_test.go:271 Min-slip cap never binds: 10 bps on 1000 RUNE allows 10-18 sub-swaps, above the 3-5 requested; the agent's probe passed with the mimir at 0.
- [careful] x/thorchain/handler_accounting_property_test.go:408 Seed-15 regression accepts any error: Only NotNil; today it is the 'LP units cannot increase' sanity check. The repeat refund at line 378 is the same.
- [careful] x/thorchain/handler_accounting_property_test.go:577 Single LP hides unfair shares: One LP owns every unit and payouts are withdraw()'s own returns, so this proves conservation, not per-LP fairness.
- [careful] x/thorchain/handler_refund_accounting_property_test.go:53 Refund sweep bound skips MaxTxOutOffset: CalcTxOutHeight can schedule past height+TxOutDelayMax; no probed refund was delayed in either build, so the sweep is untested.
- [look] x/thorchain/handler_accounting_property_test.go:97 Seed 15 forced only when N is 4: Only seed 15 of 1-32 reaches the rounded withdrawal; SEEDS=5..14 drops it and nothing asserts the path ran.
- [look] x/thorchain/handler_accounting_property_test.go:335 Final outbound checked on dummy txout store: NewTxStoreDummy skips outbound fees and height scheduling, so exact State.Out equality is not real TxOutStore behaviour.
- [look] x/thorchain/handler_accounting_property_test.go:715 Gas retention check is a lower bound: Only pool asset ≥ returned gas after the sole LP leaves; a wrong retained gas amount still passes.

## Checked and fine (AI)

- No production code changes: no consensus, migration, proto or mimir side effects.
- Each seed builds a fresh MemDB manager; the suite has no shared fields, so no state leaks between seeds.
- Persisted stream runs AdvSwapQueueMgr.EndBlock once per block and reconciles State.In/Out against bank-observed pool and Reserve deltas.
- Suite passes with mocknet tags (4 seeds, 0.6 s) and untagged (32 seeds), in a local build during this review.
- CI job mirrors the existing scheduled jobs: schedule-only rule, shared flock lock, exit-code capture, log artifact; go1.26.9 matches go.mod.

## Explainer narration (AI)

### Intro

This merge request adds seeded accounting property tests to THORNode. It changes no production code. Each campaign drives real handlers with random inputs, then checks balances against an independent ledger.

### The ledger oracle

The oracle is one equation: pool balance, plus pending deposits, plus paid out, plus the fee sent to Reserve, must equal everything that came in. A self-check moves each term by one unit and expects the ledger to break. Expected values come only from observed inputs and payouts, so the test never asks the code under test for its own answer.

### Pool flow campaign

The pool flow campaign runs twenty-four seeded steps: balanced adds, split arrivals that stage RUNE and complete with the asset, partial withdrawals, and adds with a mismatched asset address. A mismatched add must fail without touching state. Dust that rounds to zero LP units, or a withdrawal that rounds to nothing, may fail only if state is untouched. Any other rejection fails the campaign, and the first deposit into the empty pool must always mint. Each seed must also mint, complete a staged add, and withdraw at least once, so a handler that rejects everything cannot pass. It ends with a full withdrawal and checks the pool keeps the gas it returned.

### Swap flow

The swap flow keeps pool plus the RUNE fee sent to Reserve equal to starting depth plus inputs minus outputs, and LP units never move. Twelve swaps alternate direction, and every third is split into three sub-swaps. Those sub-swaps call the swapper directly, so they cover pool arithmetic and streaming event counters, not the queue or an outbound. A swap to the same asset must be rejected with no pool write, event, or outbound.

### Persisted streaming swap

A V2 market stream from RUNE to ETH is queued through the AdvSwapQueueMgr, with a ten basis point minimum slip so the deposit cap runs. Each block, the stored State.In and State.Out must match the pool and Reserve deltas, and no outbound may appear early. On the last block the item leaves the queue, and exactly one outbound of the released ETH goes to the destination. One more block must not pay again. An earlier revision drove a V1 message through the legacy queue, which production never writes while the advanced queue is on.

### Pending liabilities

A staged deposit has minted no units, but it is still owed: a full withdrawal refunds exactly the staged RUNE, and repeating it pays nothing and changes nothing. A native RUNE add moves exactly the deposit from the account to Asgard, and records it as pending on both pool and LP. A bad memo moves nothing. Seed fifteen found a one basis point withdrawal of six hundred sixty four units that rounds to zero. It is now pinned as a regression: rejected, with no state change.

### Refund outbound obligation

A DOGE inbound is refunded, and the refund must create one outbound, no larger than what came in. Because an outbound can be delayed, the test scans every height in the TxOutDelayMax window, not just the first one with items. Retrying the same refund must not add a second outbound or a second action on the inbound voter. And the vault keeps its DOGE until the outbound is observed.

### Vault funds transfer

The vault test moves coins in twelve random steps from a retiring Asgard record to an active one, saving both through the keeper each time. The two balances must always add up to the starting amount, dust included, and the pool must not change. It checks bookkeeping only. No migrate outbound is scheduled or observed, and the test was renamed to say so.

### Seeds and CI

By default the suite runs four seeds: one, two, three and fifteen. THORNODE_ACCOUNTING_SEED pins one seed to reproduce a failure, and THORNODE_ACCOUNTING_SEEDS runs seeds one to N, up to two hundred fifty six. The script runs four or thirty two. A new scheduled CI job runs the thirty two seed campaign in the long test stage, and keeps its log as an artifact. The default four seeds also run in the normal unit test job.

### In short

In short: an independent ledger, checked after every step. Real code paths where it matters: the advanced swap queue, the deposit handler, and the refund path. Every rejection must leave no trace. And the comments state the limits: the sub-swaps skip the queue, and the vault test is bookkeeping, not churn.

## Line-by-line walkthrough (AI)

Each step: the head lines it covers, its flag if any, and what the narration says.

### Suite and seeded identities: x/thorchain/handler_accounting_property_test.go

- L1-19: The file sits in package thorchain, so it can call package-private handlers such as addLiquidity, withdraw and refundTx directly, under gocheck.
- L21-26: The header comment states the design: the ledger lives outside Pool and LP. The oracle only adds observed inputs and payouts; it never calls the pool, swap or withdrawal maths to derive an answer.
- L28-33: Vault public keys come from a fixed secret per label, so vault A is the same key in every run.
- L35-47: Transaction IDs and signers are cut from a sha256 of the seed and a label, so each seed replays with identical identities.
- L49-60: Thor and ETH addresses come from the same digest. The ETH helper panics on a bad address, which cannot happen for twenty fixed bytes.

### Ledger oracle: x/thorchain/handler_accounting_property_test.go (accountingLedgerBalanced)

- L62-65: accountingLedgerBalanced is the whole oracle. On the RUNE side, pool plus pending plus paid plus the Reserve fee must equal everything in; the asset side is the same without a fee term.
- L67-75: The self-check builds one balanced ledger, then bumps a single term by one unit per row, and every bumped row must fail. It bumps four of the nine terms: RUNE pool, RUNE pending, asset paid and the fee. The equation is linear, so the rest follow, but the claim says any term.

### Seed selection: x/thorchain/handler_accounting_property_test.go (accountingPropertySeeds)

- L77-84: A single seed in THORNODE_ACCOUNTING_SEED wins outright, which is how a failing trace is reproduced. A bad value panics the test.
- L85-92: Otherwise THORNODE_ACCOUNTING_SEEDS sets a count, four by default, and anything outside one to two hundred fifty six panics.
- L93-101 [careful: seed 15 only swaps in at N=4]: Seeds run from one to N. When exactly four are asked for, the fourth becomes seed fifteen, the one that once reached a rounded-to-zero withdrawal. The fast script mode gets the same set.

### Pool flow: setup and check: x/thorchain/handler_accounting_property_test.go (accountingPoolFlow)

- L104-108: TestPoolFlowConservation runs the pool campaign once per seed.
- L526-538: Each seed gets a fresh manager and its own random source. One LP has a RUNE address, an asset address, and a second asset address for the mismatch case.
- L539-545: The pool starts empty, available, at eight decimals, and the add handler and constants are built once.
- L546-551: The ledger tracks in and paid per side, counters track which transitions happened, and every failure prints the full step trace.
- L552-557 [careful: matches error message text]: The only tolerated add rejection is dust that rounds to zero LP units, recognised by its error text. Anything else fails, even if state is untouched; before this change any unchanged-state rejection passed.
- L558-566: The check reloads the pool and the LP.
- L567-573: The pool's balances plus its pending inbound plus what was paid out must equal what came in. Liquidity moves have no fee term.
- L574-579 [careful: single LP: shares untested]: With one LP, its pending RUNE and asset must equal the pool's pending, and its units must equal all pool units. One LP owning everything means this proves conservation, not that each LP gets a fair share.

### Pool flow: twenty-four steps: x/thorchain/handler_accounting_property_test.go (accountingPoolFlow)

- L581-590: The amount menu runs from one unit to a hundred RUNE. Each step reloads the pool and LP as the before picture.
- L591-608: Every sixth step, once units exist, adds with a different asset address. It must fail, and the pool's balances, pending, units and event count must not move. The comment also promises no outbound change, which this branch does not check.
- L609-614: Every fourth step withdraws one, three thousand three hundred thirty three, five thousand or nine thousand nine hundred ninety nine basis points.
- L615-627 [careful: rounding rejection = sanity-check text]: A withdrawal error is only allowed if it is the LP units cannot increase sanity check, which is how a withdrawal that rounds to zero fails. Then pool, LP, events and returned amounts must be exactly as before.
- L628-632: A successful withdrawal adds its RUNE and asset to paid, and counts one withdrawal.
- L634-640: Otherwise two random amounts are drawn. The very first deposit into the empty pool is forced to one RUNE and one ETH, and must mint.
- L641-650: On every third step the deposit arrives split: RUNE is staged first, which must always succeed, and the check then sees it as pending.
- L651-669: The asset leg completes it. Dust may be rejected, but never on the seeding deposit, and a rejection must leave pool, LP and events untouched. The staged RUNE stays pending, so the ledger still balances.
- L670-689: The other steps add both sides at once, under the same rejection rule, and count a mint.
- L690-692: Both success paths add the asset to in, and run the check.

### Pool flow: vacuity guard and full withdrawal: x/thorchain/handler_accounting_property_test.go (accountingPoolFlow)

- L693-702: The guard added in this change: each seed must have minted, completed a staged add, and withdrawn. A handler that rejected every deposit used to pass with withdrawals skipped.
- L703-711: The LP must still hold units, and a ten thousand basis point withdrawal must succeed.
- L712-719: Its payout goes to paid, and the pool must keep at least the gas it reported, since the full withdrawal holds back the outbound gas. That only bounds the gas from above; a wrong gas amount would still pass.

### Swap flow: twelve swaps: x/thorchain/handler_accounting_property_test.go (accountingSwapFlow)

- L110-120: The comment is explicit about scope: sub-swaps here call the swapper directly with a fresh StreamingSwap and no destination, so they test pool maths and event counters only.
- L122-136: Each seed builds a 1000 by 1000 ETH pool with a dummy outbound store.
- L137-143: The Reserve balance is captured, and in starts at the pool's own depth.
- L144-159 [careful: fee = whole Reserve delta]: The check feeds the oracle the pool, the outputs as paid, and the Reserve growth as the fee. Reserve may never shrink, and LP units must not change.
- L160-168: Twelve steps alternate direction: even steps swap RUNE for ETH, odd steps ETH for RUNE, each from its own address.
- L169-179: Amounts are one to one point eight coins. Every third step is cut into three parts, and the last part takes the remainder.
- L180-193: ETH inbounds carry one unit of gas. Multi-part swaps set quantity and count, then the swapper runs against the no-op address.
- L194-203: The swap must use exactly its input, emit one event whose amount matches the output, and add to the event manager. Split parts must report their count.
- L204-212: Inputs go to in, outputs to paid, and the ledger is checked after every part.

### Swap flow: same-asset rejection: x/thorchain/handler_accounting_property_test.go (accountingSwapFlow)

- L214-220: Before the bad swap, it snapshots the pool, the event count and the outbound items.
- L221-229: An ETH to ETH swap is built and must be rejected.
- L230-236: The pool must deep-equal its snapshot, with no new event and no new outbound, and the ledger check runs once more.

### Stream: queue a V2 swap: x/thorchain/handler_accounting_property_test.go (accountingPersistedStream)

- L238-248: This test is new in this change. The advanced queue keeps a V2 stream's running in and out in its state, and settleSwap pays the out once, at the end.
- L250-265: Same 1000 by 1000 pool and dummy outbound store, with the Reserve captured.
- L267-273 [careful: cap runs, never binds]: L1SlipMinBps is set to ten basis points so admission runs the streaming cap. But one RUNE per sub-swap allows ten to eighteen sub-swaps, above the three to five asked for, so the cap is computed and never binds. Setting it to zero still passes.
- L274-284: The output leg is ETH, an L1 chain, so the dummy store records it. The message is a V2 market swap with that quantity and interval one.
- L285-289: AddSwapQueueItem admits it, and the stored item must keep the requested quantity, so the stream was not collapsed into one swap.

### Stream: block by block: x/thorchain/handler_accounting_property_test.go (accountingPersistedStream)

- L291-301: outbounds filters the scheduled items to this stream's inbound hash.
- L302-313: released derives, from balances only, the RUNE the pool and Reserve absorbed and the ETH the pool gave up. It also asserts Reserve never shrinks and LP units are fixed.
- L315-318: Each loop advances one block, runs the queue's EndBlock, and observes.
- L319-327: Before the last block, the item must still be queued with the right count and no failed swaps. Its State.In and State.Out must equal what the balances say, and no outbound may exist yet.
- L328-336: On the last block the item is gone, the RUNE consumed equals the deposit, and exactly one ETH outbound, to the destination, equals what the pool released. The outbound lands in the dummy store, which skips outbound fees and delay, so exact equality holds only before the real store's behaviour.
- L338-342: One more block runs, and there must still be only one outbound.

### Pending liquidity refund: x/thorchain/handler_accounting_property_test.go

- L344-356: A staged deposit has minted no units but is still owed. Each seed starts with an empty ETH pool.
- L357-367: A random amount of RUNE is staged, and the pool must show it as pending with zero balance.
- L368-375: A full withdrawal must return exactly the staged RUNE, no asset, units or gas, and leave the pool with nothing pending.
- L376-383: Repeating the same withdrawal must fail, pay nothing, and leave the pool and the event count unchanged. Any error is accepted here.

### Seed 15 regression: x/thorchain/handler_accounting_property_test.go

- L386-400: The seed fifteen case, minimised: a one-coin pool where one LP holds all six hundred sixty four units.
- L401-405: It snapshots pool, LP and events.
- L406-409 [careful: accepts any error]: A one basis point withdrawal rounds to zero units, so it must fail and return nothing. Only a non-nil error is required. Today it is the LP units cannot increase sanity check; any other error would pass too, as long as state holds.
- L410-416: Pool and LP must deep-equal their snapshots, with no new events.

### Native deposit pending: x/thorchain/handler_accounting_property_test.go

- L418-427: Each seed sets distinct transaction bytes on the context, and adds an active node with its bond funded, which the deposit handler needs.
- L428-443: A 100 by 100 ETH pool, a signer funded with twice the deposit, and the account, Asgard and event counts captured.
- L444-451: A native ADD deposit runs through the real deposit handler. The account must drop by exactly the amount, and Asgard grow by it.
- L452-459: The pool records it as pending RUNE without touching balances, the LP records the same pending, and events were emitted.
- L461-473: A BOGUS memo must fail and leave pool, LP, both balances and the event count exactly as they were.

### Vault funds transfer: x/thorchain/handler_accounting_property_test.go

- L477-484: The comment, rewritten in this change, limits the claim: this is vault bookkeeping and persistence only. No migrate outbound is scheduled or observed, so it cannot catch a churn that misses a credit.
- L485-505: A retiring and an active Asgard vault are created, and the retiring one gets a hundred ETH plus random dust.
- L506-513: Twelve times, a random slice is debited from retiring, must leave no deficit, is credited to active, and both are saved.
- L514-521: Reloaded from the keeper, the two balances must sum to the start, and the pool must be unchanged. The test moves the coins itself, so the sum holds by construction.

### Refund outbound obligation: x/thorchain/handler_refund_accounting_property_test.go

- L1-15: The second file adds the refund campaign. A refund is a bounded outbound liability, and the vault keeps the coin until the outbound is observed.
- L16-36: Each seed uses a fresh handler wrapper, a DOGE pool, an active vault holding the inbound amount, and a network fee for DOGE.
- L37-45: A withdraw memo inbound from another key to the vault is observed at height one thousand twenty four.
- L46-63 [careful: bound skips MaxTxOutOffset]: The outbound collector now scans every height from now to TxOutDelayMax ahead, about seventeen thousand blocks, because CalcTxOutHeight may delay an item. Before, it stopped at the first height with items, so a later duplicate went unseen. CalcTxOutHeight can still land past this bound, by up to the max outbound offset, and no probed refund was delayed at all.
- L64-68: actions reads the inbound voter's recorded refund actions.
- L69-79: The first refund must create one DOGE outbound, above zero and at most the inbound, leave the vault balance intact, and record one action.
- L80-89: A retry must leave exactly one outbound of the same amount, one action of the same amount, and the vault still full.

### Runner script: scripts/test-accounting-property.sh

- L1-11: The runner takes fast, four seeds, or campaign, thirty two. Anything else prints usage and exits two.
- L13-17: It runs from the repo root, pins the go toolchain, caches builds under the temp dir, and caps GOMAXPROCS at four. An explicit THORNODE_ACCOUNTING_SEEDS still overrides the mode.
- L19-20 [verify: no -tags mocknet, no -run]: It waits up to ten minutes for the shared test-quality build lock, then filters gocheck to AccountingPropertySuite in the thorchain package. There is no mocknet tag, so the deep run uses mainnet constants, with the advanced queue off, unlike the unit job. And without a run filter, the package's other top-level tests run too.

### Scheduled CI job: .gitlab-ci.yml

- L1127-1136: The new job runs on the small runner, only in scheduled pipelines, in the long-test stage after unit tests if present, with a thirty minute timeout.
- L1137-1142: It installs util-linux for F lock, then the usual private Go auth and stable mtimes.
- L1143-1145: The script logs the campaign to a file, prints it, and exits with the runner's code, the same shape as the security fuzz job.
- L1146-1149: The log is kept as an artifact, pass or fail.

## Glossary (AI)

- **Accounting oracle**: accountingLedgerBalanced: pool + pending + paid + Reserve fee must equal everything that came in, per side. Built from observed balances, never from the code's own maths. [handler_accounting_property_test.go](https://gitlab.com/thorchain/thornode/-/blob/33516874aac5bb77abd195ddac72c06bd4b812c0/x/thorchain/handler_accounting_property_test.go)
- **Advanced swap queue**: The swap queue used while EnableAdvSwapQueue is on. A V2 stream's running input and output live in msg.State until settleSwap pays one outbound. [docs/swap-guide/advanced-swap-queue.md](https://gitlab.com/thorchain/thornode/-/blob/33516874aac5bb77abd195ddac72c06bd4b812c0/docs/swap-guide/advanced-swap-queue.md) [streaming-swaps.md](https://gitlab.com/thorchain/thornode/-/blob/33516874aac5bb77abd195ddac72c06bd4b812c0/docs/swap-guide/streaming-swaps.md)
- **Asgard vault**: A TSS-controlled vault holding L1 coins. A retiring one hands funds to the active one during churn; the vault test only checks the bookkeeping. [types/type_vault.go](https://gitlab.com/thorchain/thornode/-/blob/33516874aac5bb77abd195ddac72c06bd4b812c0/x/thorchain/types/type_vault.go)
- **Basis points (bps)**: Hundredths of a percent. A withdrawal of 10,000 bps takes the whole position; 1 bps of 664 units rounds to zero.
- **gocheck**: The gopkg.in/check.v1 test framework. AccountingPropertySuite is a gocheck suite, selected with -check.f, and runs inside go test ./x/thorchain. [pkg.go.dev](https://pkg.go.dev/gopkg.in/check.v1)
- **L1SlipMinBps**: Mimir for the minimum slip per streaming sub-swap. Set to 10 here so admission runs the deposit cap on stream quantity. [docs/mimir.md](https://gitlab.com/thorchain/thornode/-/blob/33516874aac5bb77abd195ddac72c06bd4b812c0/docs/mimir.md)
- **LP units**: A liquidity provider's share of a pool. Swaps must not change them; withdrawals burn them in proportion to the basis points asked for. [docs/concepts/math.md](https://gitlab.com/thorchain/thornode/-/blob/33516874aac5bb77abd195ddac72c06bd4b812c0/docs/concepts/math.md) [withdraw.go](https://gitlab.com/thorchain/thornode/-/blob/33516874aac5bb77abd195ddac72c06bd4b812c0/x/thorchain/withdraw.go)
- **Pending inbound**: RUNE or asset staged by one leg of a split (asymmetric-arrival) liquidity add. It mints no LP units yet but is still owed to the depositor. [handler_add_liquidity.go](https://gitlab.com/thorchain/thornode/-/blob/33516874aac5bb77abd195ddac72c06bd4b812c0/x/thorchain/handler_add_liquidity.go)
- **Reserve**: The protocol's RUNE module account. Swap fees in RUNE go there, so the oracle counts its growth as the fee term. [docs/concepts/economic-model.md](https://gitlab.com/thorchain/thornode/-/blob/33516874aac5bb77abd195ddac72c06bd4b812c0/docs/concepts/economic-model.md)
- **Seed**: The math/rand source for one campaign run. THORNODE_ACCOUNTING_SEED pins one; THORNODE_ACCOUNTING_SEEDS runs 1..N (default 4, with seed 15 as the fourth). [scripts/test-accounting-property.sh](https://gitlab.com/thorchain/thornode/-/blob/33516874aac5bb77abd195ddac72c06bd4b812c0/scripts/test-accounting-property.sh)
- **TxOutDelayMax**: Most blocks an outbound may be delayed (17,280 by default). The refund test scans every height in that window for duplicate outbounds. [docs/mimir.md](https://gitlab.com/thorchain/thornode/-/blob/33516874aac5bb77abd195ddac72c06bd4b812c0/docs/mimir.md)
