ENG-685: chore(graphql): regenerate public schema and hooks from API main

[islandbitcoin]

Problem

app/graphql/public-schema.graphql was last copied on 2026-09-25. It was byte-identical to lnflash/flash@362c9725a0 (ENG-608, #515). Since then the API's main gained ENG-653 payment splits (lnflash/flash#526). Codegen cannot see fields the snapshot lacks, so ENG-684 Phase 1 would cite and generate against a stale schema. This is Phase 0 of ENG-684 (spec in #769, docs/ai-assistant-tool-registry.md §10 step 0). No behavior change.

Closes #765, which schema-drift-check filed on 2026-10-12 for exactly the 11 changes below. The workflow never closes its own issue: on a match it exits 0, and on the next drift it comments on whichever tracking issue is still open. Left open, #765 would bury that next drift under a body describing this one.

Change

• Source commit: lnflash/flash main at 374e5b90f300bdbe9c6d3296530672d3518d5691 (ENG-660, ENG-660: reject and disable payment splits to inactive destination accounts flash#527, 2026-10-12). The last commit there to touch src/graphql/public/schema.graphql is aeef6b75f8ce0024e60043a2fadb67d3ec853c15 (ENG-653, [Enhancement] - Refactor map screen #526). ENG-660 did not change the public schema.
• Refresh step: the repo's own, as printed by schema-drift-check (.github/workflows/schema-drift.yml):
  curl -fsSL https://raw.githubusercontent.com/lnflash/flash/main/src/graphql/public/schema.graphql -o app/graphql/public-schema.graphql, then yarn dev:codegen.
  The fetched file (sha256 558e8793…4767) is byte-identical to the same path fetched at the pinned commit through raw.githubusercontent and through the GitHub contents API, and flash main did not move during the fetch.
• Generated output: app/graphql/generated.ts is exactly what codegen emitted, with no hand edits. app/graphql/generated.gql did not change.

What changed in the schema

All additive. graphql-inspector diff (old snapshot vs new) reports 11 changes, no breaking changes.

Kind	Added
Field	splits: [WalletSplit!]! on the Wallet interface and on UsdWallet, UsdtWallet and BTCWallet (always empty on BTC)
Mutation	walletSplitsSet(input: WalletSplitsSetInput!): WalletSplitsSetPayload!
Mutation	walletSplitDelete(input: WalletSplitDeleteInput!): SuccessPayload!
Type	WalletSplit { id, destinationWalletId, percent, enabled, createdAt }
Type	WalletSplitsSetPayload { errors, splits }
Input	WalletSplitInput { destination, percent }, WalletSplitsSetInput { walletId, splits }, WalletSplitDeleteInput { walletId, splitId }

Removed: none. Renamed: none. No screen or operation is affected.

generated.ts gains the new types plus MutationWalletSplitsSetArgs and MutationWalletSplitDeleteArgs. It does not gain useWalletSplitsSetMutation or useWalletSplitDeleteMutation: codegen emits hooks only for operations the app declares, and no app document uses these mutations yet. The hooks appear when the first PR that needs them adds the gql document. Every added export is export type, so nothing changes at runtime.

How it was tested

In a fresh worktree after yarn install --frozen-lockfile (Node 24.18.0, yarn 1.22.22):

• yarn check-code: pass. tsc, check:translations, check:codegen (regeneration reproduces the committed generated.ts byte-for-byte), graphql-check ("All documents are valid").
• yarn tsc:check: pass (735 app files, 177 test files, including generated.ts).
• yarn test: pass. 182 suites passed, 1 skipped (card-topup-cardsim, env-gated); 2365 tests passed, 6 skipped.
• yarn check:translation-drift: pass. No locale changes.
• BASE_SHA=<merge-base> node scripts/ci/lint-changed.mjs (the CI Lint gate): pass, no ESLint errors on changed lines.
• typos --config typos.toml: pass.
• graphql-inspector diff <old snapshot> <new snapshot>: 11 additions, no breaking changes.
• yarn eslint:check: fails with 1297 problems (1187 errors, 110 warnings) in 212 files. The report is identical with origin/main's copies of the two changed files, none of the problems are in them, and CI runs the changed-lines gate above instead.
• Prettier: not applied. Both files are generated byte copies and Prettier 2.8.8 reformats them on origin/main too. Formatting them would break check:codegen and the strict schema-drift-check.

No tests added: no behavior changes. The additions are erased TypeScript types. check:codegen, graphql-check and schema-drift-check already guard the snapshot, and idempotency-support.spec.ts, which reads it, still passes.

Follow-ups

• Re-point docs: Flash AI Assistant tool registry + action-card spec (design v0.2) #769's schema:N citations after this merges and before docs: Flash AI Assistant tool registry + action-card spec (design v0.2) #769 merges. docs/ai-assistant-tool-registry.md cites 40 distinct lines of the 2026-09-25 snapshot, and this PR's six insertions move 35 of them onto other text: fygaroCheckoutCreate schema:1748 would land on createInvite, UsdWallet schema:2515 on LIVENESS_FRAME, and interface Wallet schema:2828-2836 on a blank line. Shift by old line: 1-387 none, 388-1879 +3, 1880-2527 +15, 2528-2575 +20, 2576-2839 +25, 2840-2889 +28 (nothing is cited past 2889). No cited range straddles an insertion, so each range moves whole. The table below lists all 35, each checked line by line against both snapshots. Citing by symbol instead would survive the next weekly refresh. The same pass updates the spec preamble (regenerated 2026-09-25, commit ce85783bd) to 2026-10-13 and this PR's commit on main (branch head ea22f81e0; the merge gives it a new sha), marks §10 step 0 done, and can cite walletSplitsSet (schema:1894) and walletSplitDelete (schema:1887) in the declined-for-v1 list.
• ENG-697 tracks that re-point and the same one for the Phase 1 briefs. ENG-687's and ENG-688's briefs and plans cite the 2026-09-25 line numbers too (ENG-686's cite none). After this merges, ENG-688's CashoutOffer schema:786 would land on ROLLED_BACK and ENG-687's realtimePrice schema:2177 on globals: Globals. Merging this PR moves ENG-685 to Done, which clears ENG-687's blocked-by, so ENG-697 is blocked by ENG-685 and blocks ENG-687 and ENG-688. Its remap covers the table below plus three ranges only the plans cite.
• Splits UI, when built, adds walletSplitsSet / walletSplitDelete documents; their hooks generate then.
