Now that add-liquidity and pool creation submit via addLiquidity / createPool,
the legacy submitNewPosition path is dead. Remove it end to end.
App backend (AmmUiBackend):
- Drop the submitNewPosition slot/method and its newPositionError helper.
Module (AmmModuleImpl):
- Drop submitNewPosition, the m_requestPending guard, and the now-orphaned
nowMs/parseU64 helpers (+ the <chrono> include).
FFI (amm_ffi) — the plan op only submitNewPosition called:
- Delete plan.rs; remove amm_plan (extern + regenerated header), api::plan,
and PlanRequest.
- Remove the plan-only machinery it fed: QuoteBranch, NewPositionPlan,
EvaluatedQuote.plan/quote_hash, and AccountPlan's wallet_args /
requires_fresh_lp / contains / validate_ready, plus the plan construction
in quote.rs.
- Tests: drop the plan-only tests/helpers; keep quote coverage by trimming
the mixed tests to their quote assertions.
QML tests (tst_LiquidityPage):
- Remove the two legacy-submit tests (base58-only success) + the
submitNewPosition mock and its now-unused fixtures. Keep the
finishSubmitFailure test (unchanged behaviour).
quoteNewPosition and its machinery (amm_quote, buildQuoteInput, PairSnapshot,
AccountPlan preview/sources, commitment) stay — they retire with the legacy
quoting in the quote-migration vertical.
Add per-side account selectors to the create-pool form, sourced from the
wallet's token holdings, so a user holding a token in several accounts chooses
which funds each deposit. A single holding auto-selects.
Mirrors the swap card: the selector lives inside the token input card, below
the token button. AmmTokenAmountSurface gains an optional footer slot (unchanged
when unset, so add-liquidity renders as before); TokenAmountInput fills it with a
ProgramAccountSelector filtered on the token's base58 definitionId.
- LiquidityPage fetches backend.tokenHoldings(), refetching when the wallet opens
- NewPositionForm routes the chosen holdings into submissionSnapshot's createPool
call; canConfirm now requires both holdings when creating a pool (add-liquidity
is untouched — it enumerates holdings server-side)
- create-pool.mjs selects the funding account for each side before submitting
Route pool creation through the redesigned createPool op and retire the old
create-flow machinery. Add-liquidity stays on the legacy submitNewPosition.
Module (amm_module):
- createPool becomes a single-param envelope: it reads the caller-provided
lpHoldingId from the request (a new pool has no pre-existing LP holding),
dropping the requires-fresh-lp handshake — the module never creates wallet
accounts. Returns { status, error, transactionId }; unlike the swaps, a
submit failure carries a code so the UI can explain why.
Backend (AmmUiBackend):
- Expose liquidityQuote (read-only preview) and createPool slots. createPool
guards on the app's wallet-open state, forwards the request, and refreshes
balances on success. No account creation here.
UI (liquidity flow/form):
- NewPositionFlow.confirm() branches on the missing-pool signal: create ->
createPool (mint a fresh public LP account via createAccountPublic, then
submit); add -> unchanged submitNewPosition. Hex transactionId accepted.
- submissionSnapshot supplies canonical-order holdingAId/holdingBId.
- (liquidityQuote is wired to the backend but the create preview still rides
the legacy quote for now.)
Cleanup: the pool-creation confirmation poll is orphaned now that create no
longer submits via submitNewPosition. It polled the pool account by re-quoting
until poolStatus flipped to active_pool — a stopgap for the missing
transactionStatus/poll_tx on the lez module. Removed pendingPoolProbes,
poolPoller, watchPoolCreation, pollPendingPool, finishPoolProbe,
rotate/removePendingPool, pairKey, matchesSelectedPair,
selectedPoolCreationPending, poolActivated, the poolCreationPending state,
acceptPoolActivation, and their now-obsolete tests.
The add-liquidity flow stamped a `new-position.v1` schema tag on every
request and response and validated it across all three layers — the QML
plugin, the amm_module core module, and the amm_client Rust crate. It was a
cross-version compatibility guard, but these artifacts always ship together,
so the contract is honored implicitly, and the swap view already works fine
without one. Dropping it makes the liquidity view consistent with swap and
removes a layer of ceremony.
- amm_client: remove PositionRequest.schema and the unsupported_schema check
in compute_quote; drop QuoteCommitment.schema (changes quoteHash, which is
internal-only) and every "schema" response stamp; delete the SCHEMA /
NEW_POSITION_SCHEMA constants and the public export.
- amm_module: remove the SCHEMA constant and its four response stamps.
- AmmUiBackend: remove its local NEW_POSITION_SCHEMA and the stamps in
loadingContext() / newPositionError().
- QML: drop the "schema" fields from the request/envelope builders and relax
the validity gates to check status / canSubmit instead (the sole check in
NewPositionFlow now guards on a missing `status`); strip the now-dead
schema fields from the liquidity QML test fixtures.
- Also removes the last stale comment references to the deleted *Runtime
classes.
Keep wallet assets as token choices without automatically selecting a pair. Keep pool-probe amounts internal so active-pool quotes do not populate the form before user input.
Add a "Create Pool" flow to the AMM app that lets a user open a new
liquidity position — seeding a pool's initial liquidity — from token
selection and amount entry, through a confirmation dialog, to on-chain
submission.
- client crate (apps/amm/client): pure, testable protocol logic — account
decoding, pair/position modelling, and quote/plan computation — exposed to
the app over a C ABI (config/networks.json drives network selection).
- C++ runtime + backend: AmmClient, ActiveNetwork, and NewPositionRuntime,
wired into AmmUiBackend (new resolve/quote/submit slots).
- QML flow: NewPositionForm, NewPositionFlow state, NewPositionConfirmation-
Dialog, TokenSelectorModal, and reusable Amm* presentational components
(theme, surfaces, buttons) + AmountMath.js.
- tests: C++ (NewPositionRuntimeTest, ActiveNetworkTest) and QML
(tst_NewPositionForm, tst_LiquidityPage, tst_TokenAmountInput, …).
