Consolidate wallet account decoding and portfolio handling around the shared Rust IDL decoder. Simplify AMM wallet integration, remove obsolete caches and network plumbing, and cover account selection and live flows.
Add-liquidity minted a fresh LP account every time, fragmenting a position
across holdings. The New position form now has an LP-destination selector (the
same Input-mode component as the token funding rows): add-liquidity preselects
the wallet's existing LP holding so deposits consolidate, while create-pool has
none and mints a fresh one.
- addLiquidityQuote returns lpDefinitionId (base58) so the form matches holdings
- createPool/addLiquidity submit into the chosen holding, else create-fresh
- e2e: add-liquidity waits for the preselect; create-pool asserts fresh-account
The `*Raw` suffix on the module's amount/price/balance/LP fields was
redundant — every such field is already a base-unit integer, and there was
no formatted sibling to disambiguate from. Drop it across the whole wire
contract in lockstep: the amm_ffi request/response fields (snake_case
`amount_in_raw` → `amount_in`, serde `rename_all="camelCase"` keeps the JSON
keys mapped), the C++ module API, the QtRO `.rep`, the QML/app that consumes
it, the mjs tests, and the module README.
Examples: expectedOutRaw→expectedOut, minReceivedRaw→minReceived,
maxInRaw→maxIn, requiredInRaw→requiredIn, priceRaw→price, reserve{A,B}Raw→
reserve{A,B}, amount{In,Out}Raw→amount{In,Out}, expectedLpRaw→expectedLp,
lpAmountRaw→lpAmount, {max,min,minimum,actual}Amount{A,B}Raw, minimumLpRaw,
minLpRaw, selectedBalance*Raw, totalSupplyRaw, quote*Raw. This also unifies a
pre-existing inconsistency where resolvePoolAccount already emitted `reserveA`
and resolveTokens already emitted `balance`.
Kept where a formatted UI sibling of the same base name exists, so `Raw`
still disambiguates the base-unit value: amountARaw / amountBRaw (vs the
user-input `amountA`/`amountB`), balanceRaw (vs display `balance`), and
initialPriceRaw (vs formatted `initialPrice`). Also kept the format-boundary
helpers formatRaw / rawLpText / probeRaw / displayRaw / displayQuoteRaw /
boundRaw.
BREAKING: the `amm_module` public API field names change (logoscore /
Basecamp / QtRO consumers must update).
Token discovery is an app concern, not module business — same rationale as
poolList reading AMM_POOLS_CONFIG. Drop tokenList() from amm_module and have the
app read the config itself.
Expose the two TWAP oracle-setup instructions as module ops so a pool's price feeds
can be seeded from the app. Both chain into the configured oracle, seeded from
validated pool state (initial tick read on-chain) — nothing is caller-priced, and
each window is a distinct feed account.
Expose the authority-only UpdateConfig as a module op so the admin can transfer
AMM ownership. The guest change (UpdateConfig restricted to the current admin) is
already shipped; this is the module wrapper.
Return the pool's full derived state from one read instead of just existence +
reserves, so callers get the derived accounts (for future account views / oracle
setup) without re-deriving.
FFI resolve_pool: drop the `exists` boolean — the presence of data is the signal.
An existing pool returns { status:"ok", ..., poolId, defAHex, defBHex, vaultAId,
vaultBId, lpDefinitionId, reserveA, reserveB, liquiditySupply, feeBps }; a missing /
uninitialized pool is the { status:"error", error:"no_pool", poolId } error (still
carrying the derived poolId for address derivation).
Module: resolvePool -> resolvePoolAccount — { status:"error", error } envelope for
hard failures, and orient reserves + defs + vaults to the caller's requested order.
Backend + QML: rename the slot; SwapCard and NewPositionFlow switch the existence
check from pool.exists to pool.status === "ok" (reserve field names unchanged, so
no other consumer edits). no_pool still routes to create-pool; hard errors still
surface.
The liquidity token surface moved app-side (resolveTokens + custom tokens),
leaving the whole newPositionContext path dormant. Delete it end to end and
point the swap methods at the same lean program-id helper everything else uses.
Move the liquidity token selector off the module's stateful newPositionContext
onto a lean, app-owned surface, and let users add unlisted tokens by id.
FFI: new stateless `resolve_tokens` op — the app passes an explicit id set and
gets uniform selector rows `{ definitionId (base58), name, totalSupply, holdingId,
balance }`, held tokens first, unresolvable/non-fungible ids omitted. Reuses the
per-token definition/holding logic from `context`, without the network/status
envelope. Unit-tested.
Module: `resolveTokens(request, wallet_open)` reads the definitions + wallet and
calls the op (ids wrapped in a map — the universal-module glue only marshals
map/scalar inputs, not bare lists).
Backend: the app owns the id set — configured tokens (TOKENS_CONFIG) plus the
user's persisted custom ids. Held-but-unlisted tokens are NOT auto-listed (the
list mirrors the swap side); a token you hold still shows its balance once listed.
`addCustomToken` validates a pasted id by resolving its on-chain definition, then
persists it to CUSTOM_TOKEN_CONFIG (defaulting to the per-user app-data store, with
a HOME fallback so persistence never silently no-ops on an empty path).
QML: NewPositionForm/LiquidityPage take tokens/walletReady/loadingTokens as inputs
and drive selection + custom-token resolution through the backend; dropped all
newPositionContext reads and the selectable/status/code row fields.
Tests: custom-token.mjs creates token D on-chain (left out of the token config)
and verifies pasting its id resolves, selects, and persists it across a reload.
The setup script mints token D and initializes/prints the isolated
CUSTOM_TOKEN_CONFIG store
The liquidity form's fee-tier selector was fed from the module's
newPositionContext, which hardcoded an empty list — leaving the selector
blank. Source the tiers from the program instead so the UI can never
drift from what the guest accepts.
Add amm_core::SUPPORTED_FEE_TIERS: the canonical ascending list of raw
bps ([1, 5, 30, 100]), built from the existing FEE_TIER_BPS_* constants.
is_supported_fee_tier's match is left unchanged and the new const is
unused on-chain, so the guest ImageID is unaffected; a drift-guard test
locks the list to the check (every entry accepted, neighbours rejected,
ascending/deduped).
Wire it through the stack:
- FFI: amm_fee_tiers op reading SUPPORTED_FEE_TIERS -> { feeTiers: [...] }
(empty FeeTiersRequest, cbindgen header regenerated).
- Module: LogosList feeTiers() unwrapping the list, like tokenHoldings.
- Backend: QVariantList feeTiers() QtRO slot forwarding to the module.
- QML: LiquidityPage fetches backend.feeTiers() once (wallet-independent)
and injects it into NewPositionForm, which wraps each int into a
{ feeBps } row for the existing delegate. Drop the now-dead feeTiers
key from the flow's loadingContext().
Two naming cleanups on the create-pool quote, aligning it with the add / remove
counterparts (per modules/amm/INTERFACE.md). Pure renames — no behavior change.
- `liquidityQuote` → `createPoolQuote` across the stack: the FFI op
(`liquidity_quote` → `create_pool_quote`, `LiquidityQuoteRequest` →
`CreatePoolQuoteRequest`, `amm_liquidity_quote` → `amm_create_pool_quote`,
cbindgen header regenerated), the module method, the AmmUiBackend slot, and the
QML call site. It really is the create-pool quote — `addLiquidityQuote` /
`removeLiquidityQuote` are the other branches — so the old name misled.
- `initialPriceRealRaw` → `priceRaw` (request field `initial_price_real_raw` →
`price_raw`): drops the legacy "Real" and unifies the price key with the add /
remove quotes, which already return `priceRaw`. Create, add, and remove quotes
now all speak `priceRaw`; the create-vs-add routing in NewPositionFlow keys on
`request.priceRaw`.
A permissionless keeper op that refreshes a pool's stored reserves to the live
vault balances (and its TWAP tick). Same lean pattern as the other plans, but
minimal: SyncReserves is a unit instruction — no quote, no user inputs (no
amounts/slippage/deadline/holdings), and nothing signs.
FFI (modules/amm/ffi):
- sync_reserves_plan: encodes SyncReserves over the fixed 6-account IDL order
(config, pool, vault_a, vault_b, current_tick, clock), all non-signing.
config/pool/current_tick/clock are order-independent PDAs from derive_pair;
the vaults come from the pool's stored ids in pool_data (read-only, but the
guest still asserts them — a non-canonically-stored pool would otherwise
mismatch). Fails closed: same_token_pair, config_unavailable, no_pool.
- Wired through mod.rs / ffi.rs (cbindgen header regenerated). Tests cover the
stored-vault + zero-signer + unit-instruction layout and the fail-closed
paths. amm_ffi: 43 tests pass, clippy clean. (lib.rs is a cargo fmt re-wrap.)
C++ module (modules/amm/src):
- syncReserves reads config + pool server-side, calls the plan, and submits.
request is just { tokenAId, tokenBId } — no holdings/amounts/deadline. Public
method → auto-exposed via the universal-module dispatch.
The remove-liquidity counterpart of the add ops, following the same lean
pattern: pure Rust FFI pricing/plan + thin C++ orchestration, hex ids end to
end, the token pair oriented to the pool's stored order server-side. No UI yet.
FFI (modules/amm/ffi):
- remove_liquidity_quote: burning lpAmountRaw returns the proportional share of
each reserve — withdraw = floor(reserve·lp/supply), the guest's own math —
plus the slippage-floored minimumAmount{A,B}Raw the submit enforces and the
pool's spot price, all in the caller's display order. Guards: same_token_pair,
invalid_slippage, no_pool, insufficient_pool_liquidity (burn exceeds the
supply unlocked above MINIMUM_LIQUIDITY), pair_mismatch, amount_too_low,
minimum_amount_zero.
- remove_liquidity_plan: encodes RemoveLiquidity over the fixed 10-account IDL
order, orienting (min_amount, holding) to the pool's stored order like the add
plan — but only user_holding_lp signs (it is burned) and there is no fresh
holding: the existing token a/b holdings receive the withdrawal.
- Wired through mod.rs / ffi.rs (cbindgen header regenerated). Unit tests cover
the guest-formula pricing + display orientation, the guard set, the plan's
account/signer layout, and fail-closed. amm_ffi: 41 tests pass, clippy clean.
C++ module (modules/amm/src):
- removeLiquidityQuote / removeLiquidity mirror addLiquidityQuote / addLiquidity:
read the pool server-side, call the ops, submit. removeLiquidity takes no fresh
account (the LP holding already exists) and threads the caller-provided
deadlineMs like the other submits. Public methods → auto-exposed via the
universal-module dispatch.
Both liquidity branches now quote through the lean ops (liquidityQuote /
addLiquidityQuote), so quoteNewPosition and the heavy amm_quote machinery it
drove are unreachable. Remove them end to end.
FFI (modules/amm/ffi):
- Drop the amm_quote entry point and the whole quote-evaluation graph:
api/{accounts,commitment,funding,position}.rs, the QuoteRequest /
PositionRequest / PairSnapshot request types, quote_error::fatal_quote, and
api/clock.rs (its decode_clock was quote-only). quote.rs keeps only the shared
opening-deposit math (minimum_opening_pair + helpers) that liquidity_quote
reuses.
- Trim the fields the quote path was the sole reader of: SelectedHolding.account
and PairIds.{token_program,twap_program}.
- Drop the quote-path unit tests; keep the math / pair / context / holding /
swap ones (37 pass, clippy clean).
Module (modules/amm/src):
- Remove AmmModuleImpl::quoteNewPosition and its buildQuoteInput snapshot helper.
App (apps/amm):
- Remove the AmmUiBackend quoteNewPosition slot (.rep/.h/.cpp) and the dead QML
backend mock + obsolete fresh-quote test.
- finishSubmitFailure no longer keeps a submit-returned re-quote (the lean submit
ops never return one); it always re-quotes on failure.
- submissionSnapshot drops the always-empty quoteHash and derives the confirm
dialog's action from the resolved pool state instead of the dead
quotePayload.instruction (restores the "Create pool" / "Add liquidity" label).
Both liquidity branches now quote through the lean composable ops. The create
path joins the add path (already on addLiquidityQuote) by reworking
liquidity_quote into a dual-mode create quote and wiring the form to it via
the resolvePool pool read. quoteNewPosition/amm_quote are no longer reached
from the UI.
FFI (modules/amm/ffi):
- liquidity_quote is dual-mode: price-only (initialPriceRealRaw, no amounts)
returns the minimum opening deposit via minimum_opening_pair; supplied
amounts return the actual deposit with the price derived from them. Emits
actual/minimum amounts, expectedLp, lockedLp and the Q64.64 price.
- LiquidityQuoteRequest gains initial_price_real_raw (Option<String>, needed
only in price-only mode).
Module (modules/amm/src):
- liquidityQuote forwards initialPriceRealRaw to the op.
UI (apps/amm/qml):
- Route create-vs-add on the pool read (resolvePool -> poolExists); create
quotes via liquidityQuote, assembled into the missing-pool shape the form
already consumes.
- poolStatus moves off the quote onto the flow's poolExists; the form derives
activePool/missingPool from it. Trim the vestigial quote fields (canSubmit,
requiresFreshLp, warnings, errors[], accountPreview, the "Pool" row) and drop
the account-plan panel for parity with the swap view.
- Fix a real bug: a pair change now resets poolExists (resetPoolExistence) so
resetPairDraft re-resolves the pool like a fresh selection. Otherwise an
active pool kept stale (cleared) reserves with no re-quote, and the deposit
ratio-fill silently no-op'd.
Tests (apps/amm/tests):
- Read activePool instead of the removed poolStatus. The add test waits for the
reset's active-pool quote to settle (reserves reloaded) before the ratio-fill;
the create test resets the draft to clear leftover cross-run amounts and the
stale submitted transactionId.
The add-liquidity quote now takes slippageBps and returns minimumLpRaw =
floor(delta_lp * (10000 - slippage) / 10000) — the LP floor the submit passes as
min_amount_liquidity, mirroring the swap quotes' minReceivedRaw. Computing it in
Rust keeps the u128 slippage math out of the UI. Adds invalid_slippage (>= 100%)
and minimum_lp_zero (slippage leaves no floor) errors; the module's
addLiquidityQuote forwards slippageBps.
resolvePool now normalizes base58-or-hex ids (the liquidity view passes base58,
the swap card hex) and orients the returned reserves to the caller's requested
token order — reserveA is the requested tokenA's reserve — instead of the pool's
stored order, which needn't be canonical (e.g. a pool created outside the FFI,
like the testnet setup's). Callers read reserveA/reserveB directly; the swap card
is unaffected (it reads the reserves for display only and never oriented them
itself).
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.
Introduce the add-liquidity vertical mirroring the swap + createPool patterns,
for depositing into an existing pool via the AddLiquidity instruction.
FFI (amm_ffi):
- add_liquidity_quote — decode poolData, orient the caller's max amounts to the
pool's canonical order, run the guest's exact ideal->actual->delta_lp math, and
return { amountARaw, amountBRaw, expectedLpRaw, priceRaw } in display order.
Slippage-free like create's quote; the min-LP floor is applied at submit.
- add_liquidity_plan — canonicalize (token, max-amount, holding) as one unit,
take vaults + LP definition from poolData, emit the 10-account AddLiquidity
order (only the user holdings a/b/LP sign). Takes minLpRaw directly, like
swap_exact_in_plan takes min_out.
Shared with createPool: extract canonical_triples (the pair/amount/holding
canonical swap) and plan_response (the tx-submission envelope); both the create
and add plans now use them.
A thin source for the account selector: an amm_ffi op that decodes the wallet's
fungible TokenHoldings (owned by the configured token program) into
[{ accountId (hex), accountType:\"TokenHolding\", definitionId (base58),
definitionIdHex (hex), balanceRaw }] — one row per holding account, every token,
including zero-balance holdings; narrowing to a specific token is the selector's
job. Exposed via AmmModuleImpl::tokenHoldings and the AmmUiBackend tokenHoldings()
slot, both gated on wallet-open.
Bring pool creation onto the redesigned lean module surface
mirroring the shipped swap vertical.
FFI (amm_ffi):
- amm_liquidity_quote: a pure create-pool preview from the two deposit
amounts — expectedLpRaw / initialPriceRaw / lockedLpRaw via the shared
amm_core opening-LP math (isqrt_product, MINIMUM_LIQUIDITY,
spot_price_q64_64), so the preview equals what new_definition mints. No
chain reads, no quoteHash, and no fee input (the fee is neither part of the
pool PDA nor the pricing — one pool per pair).
- amm_create_pool_plan: canonicalizes the pair, moving amounts and user
holdings as one unit so each (vault, holding, amount) triple names the same
token, then emits the fixed 11-account NewDefinition plan (only the user
a/b and fresh LP holdings sign).
Module (AmmModuleImpl):
- liquidityQuote(request): thin preview wrapper, normalizes ids to hex.
- createPool(request, fresh_lp_id): a new pool always needs a fresh LP
holding, so an empty fresh_lp_id returns requiresFreshLp without
submitting; otherwise builds the plan and submits, returning a hex
transactionId.
Server-side SwapExactOutput submission, mirroring the exact-in path. The
swap_exact_out_plan FFI op resolves the pool via the shared derive_pair,
encodes amm_core::Instruction::SwapExactOutput { exact_amount_out,
max_amount_in, deadline }, and returns the same four tx-submission fields as
swap_exact_in_plan (programId, accountIds, signingRequirements, instruction)
in the identical fixed 8-account IDL order — only the user's input holding
signs. Recoverable domain failures (same_token_pair, config_unavailable) go
through the FFI envelope as Err. C export amm_swap_exact_out_plan (cbindgen
header regenerated).
The module swapExactOutput(defA, defB, userIn, userOut, amountOut, maxIn,
deadline) method reads the AMM config, calls the op, and submits the plan via
send_generic_public_transaction, returning the tx hash (empty string on
failure). Same argument conventions and I/O-free split as swapExactInput.
Not yet wired into AmmUiBackend/QML — the SwapCard rewire is a follow-up. The
existing swap UI path is untouched, so nothing breaks.
The plan op is internal plumbing — its only consumer is the module's
swapExactInput, which just forwards the four tx-submission fields to the
wallet. Collapse its response onto the FFI envelope: return { programId,
accountIds, signingRequirements, instruction } directly and route the
recoverable domain failures (same_token_pair, config_unavailable) through
Err -> { ok: false, error } instead of a nested { status, code } object.
Also drop the deadlineMs echo — it's unused (the deadline is already encoded
in the instruction bytes). swapExactInput now treats any non-ok plan as a
failure. No behavior change for the UI: the plan JSON never crosses the
module boundary.
The swap-submission plan derived the pool's vaults from the canonical token
order (compute_vault_pda(pool, canonical_token_a/b) via derive_pair), but the
guest asserts the provided vaults against the pool's stored vault_a_id /
vault_b_id, which are in the pool's *creation* order. compute_pool_pda_seed
canonicalizes, so the pool address is order-independent, but NewDefinition
stores def_a/def_b (and their vaults) as created — so for a pool created in
non-canonical order, the plan put vault_b in the vault_a slot and the guest
panicked with "Vault A was not provided", reverting the swap.
Read the pool account in swapExactInput and pass its data to
swap_exact_in_plan, which now uses pool.vault_a_id / pool.vault_b_id verbatim
for the vault slots (pool / current_tick / clock stay from derive_pair, since
those are order-independent). This restores the order-agnostic behavior the
original swap client had before it was rewired onto the canonical derive_pair
in 737b2f6.
Adds a regression test that builds a non-canonically-created pool (stored
def_a = the smaller-valued token) and asserts the plan emits the pool's stored
vaults, guarding that they differ from the canonical derivation.
Rename the swap-submission planning op for symmetry with the exact-in/exact-out
split already applied to the quote ops (swap_exact_in_quote /
swap_exact_out_quote): swap_plan -> swap_exact_in_plan, SwapPlanRequest ->
SwapExactInPlanRequest, and the C export amm_swap_plan -> amm_swap_exact_in_plan
(cbindgen header regenerated). The module's swapExactInput call site and trace
are updated to match.
Server-side SwapExactOutput preview. The swap_exact_out_quote FFI op orients
the pool reserves to the requested in/out direction, prices via the shared
amm_core::swap_exact_out_amounts (so requiredIn matches the chain), and
derives the slippage ceiling: { requiredInRaw, maxInRaw, priceImpactBps }.
no_pool and output_exceeds_liquidity (amount_out >= reserve) are returned as
errors. Read-only — no quoteHash; the on-chain max_amount_in is the real
guard.
The module swapExactOutQuote(tokenIn, tokenOut, amountOut, slippageBps)
method derives the pool via the config-free pool_id op, reads it, and wraps
the op in the { status, error, ... } envelope. Mirrors swapExactInQuote.
Not yet consumed by the QML swap view, so nothing breaks. Lets the buy field
stay editable when the SwapCard is rewired in a follow-up.
Server-side SwapExactInput preview. The swap_exact_in_quote FFI op orients the pool reserves to the requested in/out direction, prices via the shared amm_core::swap_exact_in_amounts (so expectedOut matches the chain), and derives the slippage floor: { expectedOutRaw, minReceivedRaw, priceImpactBps }. no_pool is returned as an error; pool metadata (reserves/fee) comes from resolve_pool, so it isn't echoed. Read-only — no quoteHash; the on-chain min_amount_out is the real guard.
The module swapExactInQuote(tokenIn, tokenOut, amountIn, slippageBps) method derives the pool via the config-free pool_id op, reads it, and wraps the op in the { status, error, ... } envelope; call() now surfaces the op error code so no_pool propagates.
The QML swap view still uses the old path, so nothing breaks. Will make the QML consume it in a follow-up.
After the amm_module refactor, this crate is linked only by the module (the
UI delegates to modules().amm_module and links nothing), so its home under
apps/amm/ and the name "client" were both misnomers: it's the AMM business
logic the module wraps, reached across an FFI boundary — the same relationship
logos_execution_zone has with wallet_ffi. Co-locate it with the module that
owns it and name it for that role.
The FFI surface is unchanged — the exported functions are already amm_* (not
amm_client_*) — so only the crate, directory, generated header, dylib, and
package names move. The module's call sites are untouched; it just includes the
renamed header.
- apps/amm/client → modules/amm/ffi (git-tracked rename; history preserved)
- crate amm_client → amm_ffi: package name, include/amm_ffi.h, libamm_ffi.dylib,
AMM_FFI_H guard, build.rs output path, tests/public_api.rs import
- workspace member path + Cargo.lock
- flake.nix: pname, -p, header-copy path, dylib install_name, packages.amm_ffi,
ammModuleOutputs externalLibInputs, DYLD wrapper
- modules/amm: metadata external_libraries, CMakeLists EXTERNAL_LIBS, impl
#include + comments, README, flake note
- apps/amm/flake.nix: drop the now-dead amm_client external-lib input (the UI
links no external lib of its own)
Resulting layout:
modules/amm/
src/ # C++ module (amm_module_impl.{h,cpp})
ffi/ # Rust crate amm_ffi (Cargo.toml, src/, include/amm_ffi.h)
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.
Introduce modules/amm — the AMM business logic as a universal core Logos module,
consumed identically by the QML UI (via modules().amm_module) and headlessly
(logoscore call amm_module ...). The module is a thin transport adapter: the
domain math lives in the Rust amm_client crate (the transport-independent JSON
FFI), and the module sequences those pure ops with chain I/O delegated to the
logos_execution_zone wallet module. It reaches the same shared wallet instance
the UI opened (Basecamp loads core modules as singletons; standalone the
LogosAPI client cache dedups the connection), so it never opens a second wallet.
The module owns the full AMM surface — not just swaps:
- resolvePool / swapExactInput / tokenList (the swap path)
- newPositionContext / quoteNewPosition / submitNewPosition (add-liquidity)
apps/amm: delete the app-side orchestration (SwapRuntime, NewPositionRuntime,
AmmClient/BundledAmmClient) and the amm_client link. AmmUiBackend now owns only
wallet-session lifecycle and forwards every AMM slot to modules().amm_module.
The one wallet-keyset mutation add-liquidity needs — creating a fresh LP holding
— stays in the backend (via its wallet provider, keeping the account model and
on-disk storage coherent): the module returns "requires_fresh_lp" without
submitting, the backend creates the account and resubmits with its id.
flake.nix / CMakeLists / metadata: the module links the amm_client crate; the UI
links no external lib and depends on amm_module (injected into the UI builder's
flakeInputs so the dependency resolves).
- amounts/deadline declared nlohmann::json so the generated dispatch accepts a
JSON number (bare small ints on the CLI) or a string (exact u128 from the UI,
or a quote-wrapped big value on the CLI); JSON floats are rejected rather than
submit a silently-rounded amount.
- AMM_DEBUG-gated tracing for the swap path.
- Drop tests/cpp/NewPositionRuntimeTest.cpp with the class it covered
(module-level tests to follow).
- modules/amm/README.md: architecture, headless prerequisites, logoscore recipe.
