-# PLAN — monetization implementation
-
-Technical, step-by-step implementation of the monetization domain. Business mechanics and
-the rationale for every rule live in [`docs/PAYMENTS.md`](docs/PAYMENTS.md) (RU mirror
-[`docs/PAYMENTS_ru.md`](docs/PAYMENTS_ru.md)); this file is the *how*. Each stage is written
-to be self-sufficient: returning to it gives full context — goal, exact touch-points,
-tests, done-criteria, and current status — without re-deriving decisions.
-
-## How to use this file
-
-- **Stage granularity (E0–E9) is fixed.** Do not split or merge stages. Plan each stage
-  densely enough to execute whole.
-- **Never leak stage ids into the product.** Code, comments, commit messages, PR
-  titles/descriptions must read as finalized feature copy — never "E5", "stage 3", etc.
-  Stage ids exist only in this file.
-- **Deviations are allowed** when new unknowns surface, but the plan is then edited **whole
-  and in agreement** (not piecemeal), keeping it coherent, and `docs/PAYMENTS.md` updated in
-  step.
-- **Status marks:** each stage header carries `Status: TODO | WIP | DONE`. When a stage
-  lands, flip it to DONE and note the PR. The **Progress** table is the at-a-glance index.
-- **Per-change discipline** (repo `CLAUDE.md`): update tests at the layers `docs/TESTING.md`
-  calls out, bake doc updates into the same PR, run local full verification before pushing,
-  feature branch → PR into `development`.
-
-## Progress
-
-| Stage | Title | Release | Status |
-|-------|-------|---------|--------|
-| E0 | Payments data foundation | 1 | DONE |
-| E1 | Trusted platform signal | 1 | DONE |
-| E2 | Currency + benefit core | 1 | TODO |
-| E3 | Wallet UI | 1 | TODO |
-| E4 | Durability (PITR) | 2 | TODO |
-| E5 | Payment intake | 2 | TODO |
-| E6 | Ads | 2 | TODO |
-| E7 | Admin & reports | 2 | TODO |
-| E8 | Guest limits | — | TODO |
-| E9 | Tournament fee | future | TODO |
-
-**Release 1** = full mechanics with no real money, exercised via `admin_grant` (E0→E1→E2→E3).
-**Release 2** = money (E4→E5→E6→E7). E8 is standalone (game-behaviour change, can run in
-parallel). E9 is future.
-
----
-
-## Architecture baseline (applies to all stages)
-
-Read once; individual stages assume it.
-
-### Schema & isolation
-
-- The payments domain owns its **own Postgres schema `payments`** in the shared instance
-  (`scrabble` DB). All payments tables are `payments.*`. `backend` schema is untouched
-  except for the deprecation of two legacy columns (E2).
-- **DB role.** A dedicated **NOLOGIN** role holds ALL privileges on `payments.*` and
-  **nothing** on `backend` — grant-based confinement, asserted by a `SET ROLE` isolation
-  test. The application still connects on its single (superuser) pool, so these grants are a
-  stepping-stone to a real separate login/process, not the runtime wall. The **runtime wall
-  is code-level**: only the `internal/payments` package imports the payments jet code and
-  issues `payments.*` SQL (an **import-boundary test** enforces it); every other domain
-  reaches payments through the narrow Go interface.
-- **No cross-schema link at all.** There is **no** foreign key from `payments.*` to
-  `backend.accounts`: `account_id` is a plain `uuid`, kept referentially honest in code and
-  joined to the tombstoned account / `retained_identities` dossier by the stable id. This
-  keeps the spend transaction (ledger INSERT + balance UPDATE + benefit UPDATE) fully
-  **within `payments`** and the domain extractable into its own database later. Benefits move
-  **into** `payments` (they no longer live on `accounts` — see E2); game code reads them
-  through the payments **Go interface**, never via SQL.
-- **Money.** Monetary amounts are a single **`bigint` in the currency's minor units** (RUB
-  kopecks; Votes/Stars/chips are whole units, scale 1) carried in Go by the `payments.Money`
-  value type — the sole constructor/formatter/arithmetic, so **no `float64` ever touches an
-  amount** and a whole-unit currency structurally cannot hold a fraction. `chip_rate` is not a
-  table: a chip pack is a product, so its per-method rate **is** `product_price`.
-
-### Domain boundary
-
-- New package `backend/internal/payments/` — `payments.go` (types + `Service`),
-  `store.go` (`type Store struct{ db *sql.DB }`, go-jet against `internal/postgres/jet/
-  payments`), following the `ads` domain shape (`backend/internal/ads/{ads,service,store}.go`).
-- Wired in `backend/cmd/backend/main.go` `run()` (construct after `account`, before
-  `server.New`), handed into `server.Deps` (`server.go`), routes registered in
-  `registerRoutes` gated `if s.payments != nil`, admin section in `registerConsole` gated
-  `if s.payments != nil`.
-- Game/other domains depend on payments only through a **narrow interface** (e.g.
-  `AdFree(ctx, account, platform) bool`, `SpendHint(ctx, account, platform) error`,
-  `Balances(ctx, account, platform) …`). Keep the surface small; this is the seam that lets
-  payments become a separate process later without touching callers.
-
-### Migrations & codegen
-
-- Migrations: same goose dir `backend/internal/postgres/migrations/`, sequential
-  `0000N_*.sql`, `-- +goose Up/Down`, schema-qualified, **expand-contract mandatory**
-  (image rollback must stay DB-safe). First payments migration does `CREATE SCHEMA IF NOT
-  EXISTS payments`, creates the role, grants.
-- **jetgen** (`backend/cmd/jetgen/main.go`) is currently hardwired to `schema=backend`.
-  Extend it to also generate `schema=payments` into `internal/postgres/jet/payments/
-  {model,table}` (committed). Regenerate only after a payments migration; revert unrelated
-  `backend`-schema churn (jetgen may reorder untouched tables — commit only intended diffs).
-- Transactions: reuse the local `withTx(ctx, db, fn)` idiom. Balance/benefit mutations are
-  guarded single-row atomic UPDATEs (mirror `account.SpendHint`); the ledger INSERT +
-  materialized-cache UPDATE go in one `withTx`. Default Read-Committed is sufficient given
-  the guarded updates + unique idempotency keys; do not reach for Serializable without a
-  demonstrated need.
-
-### Transport
-
-- client ↔ gateway: Connect-RPC + FlatBuffers (h2c). gateway ↔ backend: REST/JSON +
-  `X-User-ID` via `gateway/internal/backendclient`. Any user-facing payments call needs the
-  full chain: backend REST handler (`u := s.user` group) → `backendclient` method →
-  Connect-RPC method + transcode (`gateway/internal/transcode/`) → FlatBuffers schema
-  (`pkg/fbs/…`, regen with `make -C pkg fbs` + `pnpm -C ui codegen`).
-- Provider webhooks (Robokassa/VK) do NOT use the Connect path — model on the existing
-  public HMAC-signed route `s.public.GET("/dl/:id/:kind", …)` (`handlers.go`): a public
-  route with signature verification, proxied by the gateway/Caddy `@gateway` matcher
-  (`deploy/caddy/Caddyfile` — a new edge route MUST be added there or it falls to the
-  landing catch-all).
-
-### Testing layers (`docs/TESTING.md`)
-
-- **unit** (Go `_test.go`, TS vitest): gate-by-context, no-ads stacking, priority draw,
-  rate math, idempotency keys, catalog snapshotting. UI logic must be extracted out of
-  `.svelte` into `ui/src/lib/*` to be unit-testable.
-- **integration** (`backend/internal/inttest/`, `//go:build integration`, Postgres-backed):
-  atomic chip↔benefit spend, callback idempotency, order-flow, TG outbox delivery, merge/
-  unlink of segments.
-- **UI** (Playwright mock e2e, Chromium+WebKit): Wallet screen, warnings, guest-hidden, GP
-  stub. Mock e2e bypasses codec — wire bugs need codec unit tests.
-- Local full verification before push: integration (`-tags=integration` + DAWG sibling +
-  Ryuk-off), UI check/test/build, codegen (`make -C pkg proto fbs`, `pnpm -C ui codegen`).

-## E0 — Payments data foundation
-
-**Status:** DONE · **Release 1** · depends on: none · mechanics: PAYMENTS §14, §7, §11.
-
-**Goal.** Stand up the `payments` schema, its confinement role, the jetgen target, the domain
-package skeleton and all core tables — nothing wired to real money yet. This is the substrate
-every later stage builds on.
-
-**Migration `00010_payments_foundation.sql` (`payments` schema).**
-
-- `CREATE SCHEMA payments`; an idempotent `DO $$` block creates a **NOLOGIN** `payments` role;
-  `GRANT USAGE` + `GRANT ALL ON ALL TABLES` (+ `ALTER DEFAULT PRIVILEGES … GRANT ALL`) confine it
-  to `payments.*` with nothing on `backend`. No `REFERENCES` grant (there is no cross-schema FK).
-- `payments.ledger` — append-only. `ledger_id` (uuid PK, app-generated v7), `account_id` (plain
-  `uuid`, **no FK**), `kind` (`fund|spend|admin_grant|refund`), `source`/`origin` (nullable,
-  `vk|telegram|direct`), `chips_delta` (signed int, 0 for a grant), `product_id` (nullable
-  FK→product), `order_id` (nullable FK→orders), `provider` + `provider_payment_id` (nullable),
-  `snapshot` (jsonb, written from E2), `created_at`. Immutability is a **`BEFORE UPDATE OR DELETE`
-  trigger** (a superuser bypasses a privilege REVOKE). Unique **partial** index on `(provider,
-  provider_payment_id) WHERE provider_payment_id IS NOT NULL` — the idempotency key.
-- `payments.balances` — `(account_id, source)` PK, `chips int CHECK (>=0)`, `updated_at`. Created
-  **lazily** on first fund (up to three rows/account, absent = zero).
-- `payments.benefits` — `(account_id, origin)` PK, `ads_paid_until timestamptz` null,
-  `ads_forever bool`, `hints int CHECK (>=0)`, `updated_at`. Created lazily.
-- `payments.catalog_atom` — `atom_type` PK (`chips|hints|noads_days|tournament`); the four atoms
-  are **seeded** here (the `tournament` atom is provisioned for E9).
-- `payments.product` (`product_id` PK, `title`, `active bool` soft-delete, timestamps);
-  `payments.product_item` (`(product_id, atom_type)` PK → `quantity`); `payments.product_price`
-  (`(product_id, COALESCE(method,''), currency)` unique → `amount bigint` minor units): a chip
-  pack carries a money price per `method` (`vk|telegram|direct`), a value carries one
-  `currency='CHIP', method=NULL` row. `currency ∈ {RUB, VOTE, XTR, CHIP}`; `amount CHECK (>=0)`.
-- `payments.config` — a single typed row (`only_row bool PK CHECK`): `rewarded_payout_chips`,
-  `cooldown_global_seconds` (300), `cooldown_vs_ai_seconds` (1800), `cooldown_hint_seconds` (60),
-  `order_ttl_seconds` (1800). No `chip_rate` table — the pack rate is `product_price`.
-- `payments.orders` — `order_id` (uuid PK), `account_id`, `platform`, `product_id` (FK),
-  `expected_amount bigint` + `currency`, `origin`, `status` (`pending|paid|expired`), `provider`,
-  `provider_payment_id` (nullable), timestamps. Index `(status, created_at)` for the pending sweep.
-- `payments.payment_events` — `event_id` (uuid PK), `account_id`, `order_id` (nullable FK), `type`
-  (`succeeded|failed|refunded`), `payload jsonb`, `created_at`, `dispatched_at` (nullable, partial
-  index for the dispatch queue).
-- Full `-- +goose Down` (DROP SCHEMA CASCADE + DROP OWNED BY + DROP ROLE); expand-contract, proven
-  reversible by an integration test.
-
-**Backend.**
-
-- `backend/internal/payments/{payments,service,store}.go` — the `Money` value type + `Currency`
-  (bigint minor units, exact, no float); `Store{db *sql.DB}` with a `Ping` health read via jet;
-  `Service` over the store. (`withTx` arrives with E2's first transaction.)
-- `cmd/jetgen` generates the `payments` schema into `internal/postgres/jet/payments/` (a second
-  `GenerateDB` call); committed. Constructed in `cmd/backend/main.go` and passed to `server.Deps`
-  (`Payments`) with a boot-time reachability check; its routes are registered from E2.
-
-**Legacy deprecation (expand phase only).** A `--` header note marks `accounts.hint_balance` and
-`accounts.paid_account` deprecated; they are **not** dropped (the DROP is the contract phase after
-E2 flips reads and after Release 2). Reads still use the old columns until E2.
-
-**Tests.**
-
-- integration (`inttest`): schema + role + seeds present; `SET ROLE payments` cannot read
-  `backend.accounts` (grant confinement); ledger rejects UPDATE/DELETE (trigger); idempotency
-  partial index holds (NULL-keyed rows repeat); balance/benefit/amount/enum CHECKs bite; migration
-  applies forward **and backward** on a throwaway PG.
-- unit: `Money` — exact round-trip, per-currency scale, no-float parse rejecting a fraction for a
-  whole-unit currency, arithmetic, formatting. Import-boundary test: only `internal/payments`
-  imports the payments jet code.
-
-**Done-criteria (met).** Migrations apply forward+backward on a throwaway PG 17; `go build
-./backend/...` + `go vet` + `gofmt -l .` clean; committed `jet/payments/`; all tests green; no
-behaviour change for users.
-
-**Notes.** jetgen regenerates the whole `backend` schema; its committed jet had drifted from the
-migrations (`robot_blocks`, `robot_friend_requests`, the `feedback_messages` `app_version` /
-`browser_tz` columns, and `UseSchema` gaps), so this change also **regenerates and commits
-`jet/backend`** to bring it back in sync (additive only — all suites stay green). The `payments`
-role creation is idempotent (`DO $$` / `IF NOT EXISTS`) for fresh volumes.

-
-## E1 — Trusted platform signal
-
-**Status:** DONE · **Release 1** · depends on: none (parallel to E0) · mechanics: PAYMENTS §8.
-
-**Goal.** Make the server know the execution platform from a trusted, unforgeable source,
-carried on the session. This is the foundation the gate (E2) stands on; without it the gate is
-meaningless. Signal plumbing only — no user-visible change.
-
-**Model.** `platform = {kind: vk|telegram|direct, subtype: ios|android|web}` is a property of
-the **session**, captured at creation. `kind` is always trusted — the gateway derives it from
-the validated establish path (VK launch / TG initData / a web-native session), never a client
-field. `subtype` is **cryptographically trusted only for VK** (it rides inside the signed
-`vk_platform` launch param); for telegram and direct it is client-reported best-effort, and the
-gate never relies on it (only the VK-iOS-frozen case is compliance-critical, and VK subtype is
-trusted). VK/TG re-mint a session on **every cold start**, so their platform is re-captured each
-launch; web/direct/email reuse the stored token, so their platform is captured once at creation
-(`direct` needs no signature).
-
-**Validation stays at the gateway.** Both wrapper verifiers already live there and the backend
-cannot import either (separate modules under `internal/`, and the VK app secret is gateway-only):
-VK launch params via the in-process `gateway/internal/vkauth.Verify` (HMAC-SHA256 over the signed
-`vk_*` params under `GATEWAY_VK_APP_SECRET`, extended here to expose the signed `vk_platform` →
-a trusted `Subtype()`), TG `initData` via the validator RPC. The gateway hands the derived
-platform to the backend at establish; the backend persists it and returns it on resolve.
-
-**Backend.**
-
-- `backend.sessions` gains nullable `platform_kind` + `platform_subtype` columns (migration
-  `00011`, CHECK-constrained, jet regenerated). A `session.Platform` value type + `session.Create`
-  captures it; `Session` carries it through the store and the warm cache.
-- `handleResolveSession` → `resolveResponse` (`dto.go`) returns the platform; the establish
-  handlers set `kind` from their own endpoint (`/sessions/telegram|vk|guest|email/*`) and
-  `subtype` from the request (VK: gateway-extracted from the signed params; TG/direct: the client
-  best-effort field, defaulting web). The account-merge session mint (`link.merge`) inherits the
-  caller's platform from the request context.
-- Middleware (`middleware.go`) parses the gateway-injected `X-Platform` into the request context
-  on the `s.user` group; `platform(c)` exposes it. Absent ⇒ untrusted (fail-closed).
-
-**Gateway.**
-
-- `backendclient.WithPlatform(ctx, "<kind>/<subtype>")` + `do`/`getRaw` inject `X-Platform` on
-  every authenticated backend call; `connectsrv.Execute` enriches the request context from the
-  resolved session's platform (carried through the gateway session cache + `ResolveSession`).
-  Never from a client request body.
-
-**Client (`ui/`).** `platformSubtype()` (`ui/src/lib/platform.ts`) supplies a best-effort device
-subtype on the `auth.telegram` / `auth.guest` / `auth.email.login` requests (new FBS `subtype`
-field): Telegram's `WebApp.platform` inside a Mini App, else the Capacitor/web channel. VK sends
-nothing (the gateway derives the trusted subtype from the signed launch params).
-
-**Tests.**
-
-- unit (Go): `vkauth` exposes the signed `vk_platform` and maps iPhone/iPad → ios (the frozen
-  case); the `X-Platform` middleware round-trips + reports untrusted when absent; the backend
-  client injects `X-Platform` from the context and omits it when untrusted.
-- integration: a session carries its platform through create + a cold-cache (DB) resolve for each
-  kind; an unattributed session is untrusted; the CHECK constraints bite; migration `00011`
-  applies forward **and backward** on a throwaway PG.
-- UI: subtype normalization (vitest) + the new `subtype` field on the wire (codec unit test).
-
-**Done-criteria (met).** A VK/TG session resolves to a trusted `{kind, subtype}`; a forged body
-cannot change `kind` (nor the VK subtype); `direct` sessions resolve to `direct`; the untrusted
-path is reachable and observable via `platform(c)`. No user-visible change; all layers green.
-
-**Notes/risks.** High blast-radius (auth/session table + broad gateway header threading): additive
-migration, no mixed-in refactors, `X-Platform` inert until E2 consumes it. **Sessions minted before
-E1 carry no platform → untrusted (view-only) until re-login**; VK/TG self-heal on the next
-cold-start re-mint, direct/email do not (accepted: Release 1 has no money, sessions cycle by
-Release 2). TG/direct subtype is not cryptographically trusted — E2 must keep the gate on `kind`
-+ the trusted VK subtype only.

-
-## E2 — Currency + benefit core
-
-**Status:** TODO · **Release 1** · depends on: E0, E1 · mechanics: PAYMENTS §2–§6, §11.
-
-**Goal.** The full internal money mechanic, exercisable end-to-end **without real money**
-via `admin_grant`: chip balances, spend→benefit atomically, the compliance gate by context,
-benefit application (no-ads stacking, hints per-origin), the legacy migration, and the
-`SpendHint` rewrite. This is the heart.
-
-**Payments service (Go).**
-
-- `Balances(ctx, account, platform)` → the segments spendable in the platform's context
-  (VK→vk; TG→tg; direct→direct+vk+tg; VK-iOS→frozen/view; untrusted→none).
-- `Spend(ctx, account, platform, productID)` → gate-checked purchase of a value with chips:
-  resolve spendable segments by context, draw by priority (direct→vk→tg on web), write a
-  `spend` ledger row + decrement balance + apply benefit (extend `ads_paid_until[origin]`
-  from `max(now,end)` / set `ads_forever` / add hints) **in one tx**, stamping `origin` =
-  platform context. Refuse if untrusted (fail-closed) or funds insufficient.
-- `Grant(ctx, account, origin, atoms)` → `admin_grant` ledger row (price 0, concrete values
-  only, never chips), same benefit application; origin chosen by the admin (E7 UI; here the
-  service method + an internal/admin entrypoint).
-- `AdFree(ctx, account, platform)` / `HintsAvailable(ctx, account, platform)` /
-  `SpendHint(ctx, account, platform)` → apply the one-directional origin rule: in context P,
-  usable origins = {P} plus, when P is web/native, {vk,tg} (relaxation outward); in VK only
-  vk; in TG only tg.
-- `Merge` / `Unlink` hooks: extend `accountmerge` to merge segments+benefits by origin
-  (same-origin add, different coexist), and make segment availability follow identity
-  presence (unlink → sleep, re-link → wake). Warn-before-unlink is a UI concern (surface the
-  balance via the interface).
-
-**Backend wiring & migration.**
-
-- Deprecate-and-flip `accounts.hint_balance` / `accounts.paid_account`: E0 added the tables;
-  here, move reads/writes to `payments.benefits`. `SpendHint` (`game/service.go` ~:1147) and
-  `ads.Eligible` (`ads/ads.go` :107) call the payments interface instead of the account
-  columns. Legacy values were never set in prod → zero them; the DROP is the contract phase
-  (guarded, after Release 2 — keep columns until then for rollback safety).
-- `vs_ai` hints stay free/unlimited (unchanged 30-min gate); only online-game hint spend
-  routes through the segmented, context-aware path.
-
-**API (user-facing, Connect chain).** Read-only wallet view + spend:
-`GET /api/v1/user/wallet` (balances+benefits for the context), `POST /api/v1/user/wallet/
-buy` (spend chips on a product). Add the backend handlers (`u := s.user`), `backendclient`
-methods, Connect methods + transcode + FBS. Admin grant is internal/admin (E7 UI).
-
-**Tests.**
-
-- unit (Go): gate-by-context matrix (every row of PAYMENTS §4); priority draw; no-ads
-  stacking (`+=` from max(now,end)) + forever override; per-origin hint applicability;
-  merge/unlink segment math.
-- integration: atomic spend (ledger+balance+benefit in one tx; failure rolls all back);
-  admin_grant credits values not chips; legacy migration zeroes and flips reads; merge/
-  unlink over Postgres.
-- UI: none new (E3 builds the screen); wallet DTO covered by codec unit tests.
-
-**Done-criteria.** With chips seeded via `admin_grant`, a user can buy no-ads/hints; the gate
-blocks cross-context spend and cross-origin application; ads gate reads the new benefit;
-`SpendHint` uses segments; all layers green; **compliance regression** (a `direct` benefit
-never activates inside VK/TG) is a named test.
-
-**Notes/risks.** This is the high-blast-radius core (money semantics + a live path
-`SpendHint`/`ads.Eligible`). Minimize surface, keep the interface narrow, no mixed-in
-refactors. The legacy flip is expand-contract: reads move first, DROP much later.

-## E3 — Wallet UI
-
-**Status:** TODO · **Release 1** · depends on: E2 · mechanics: PAYMENTS §1, §7, §6, §13, §4.
-
-**Goal.** The user-facing "Кошелёк" (Wallet) section: balances + active benefits + the
-catalog storefront, honouring guest-hidden, GP-stub, and the web-spend warning.
-
-**UI (`ui/`).**
-
-- New `'wallet'` tab in `ui/src/screens/SettingsHub.svelte` — `SettingsTab` union, tab
-  button **between Friends (:65) and About (:66)**, body branch in the `:42-51` switch,
-  `'wallet'` route in `ui/src/lib/routeparse.ts` + `ui/src/App.svelte`. Reuse the hub's
-  guest/offline gating.
-- `Wallet.svelte` screen: **minimal** — context-available chip balances + active benefits
-  (no-ads until date, hints count). **No history feed** (PAYMENTS §11 — noise). Storefront:
-  products from the configurable catalog, prices in chips (values) / per-method (chip packs).
-- **Guest:** section hidden entirely (durable-only).
-- **GP build:** purchase CTA replaced by a stub ("install the RuStore build to make
-  purchases"); rewarded + spending earned chips still work. Detect the GP native build.
-- **Web-spend warning:** before spending vk/tg chips in a web/native (direct) context, show
-  an own `Modal` (not `showPopup` — that eats the user-activation gesture) warning the value
-  will be web/native-only.
-- Extract all logic into `ui/src/lib/*` (unit-testable); keep `.svelte` thin.
-
-**Tests.**
-
-- unit (vitest): storefront/price formatting, context-available-segment selection, warning
-  trigger condition.
-- UI (Playwright mock, Chromium+WebKit): Wallet renders between Friends/About; guest hides
-  it; GP stub; warning modal on web vk/tg spend. Mock overlay must stay instant under
-  `MODE==='mock'` (or it intercepts taps).
-
-**Done-criteria.** Owner can review the Wallet on the deployed test contour (visual sign-off
-is on the contour, not local); balances/benefits/storefront correct per context; guest/GP/
-warning paths verified. Release 1 is now demonstrable end-to-end via `admin_grant`.
-
-**Notes/risks.** No global `.btn`/`.ghost` in `ui/` — style per-component with scoped CSS +
-tokens (mirror NewGame `.invite` for a CTA). Svelte whitespace/`$state` naming gotchas
-apply. iOS WebView download/gesture caveats are irrelevant here (no file delivery).

-## E4 — Durability (PITR)
-
-**Status:** TODO · **Release 2** · depends on: E0 (schema exists) · mechanics: PAYMENTS §14.
-
-**Goal.** Continuous WAL archiving with point-in-time recovery, armed **before the first
-real money** is accepted (E5 prod). Protects both money and game data.
-
-**Work.**
-
-- Add WAL archiving to the prod Postgres (pgBackRest or WAL-G): base backups + continuous
-  WAL to a second host or object storage. Wire into `deploy/` (compose/prod overlay +
-  ansible `deploy/ansible/`), config + secrets under the `PROD_` prefix.
-- Restore runbook in `deploy/README.md`: base + WAL replay to a timestamp; test the restore
-  on a scratch target.
-- Keep the existing migration-time `pg_dump` (`deploy/prod-deploy.sh`) as belt-and-braces.
-
-**Mandatory pre-prod assessment (owner-required, gates the Release 2 prod rollout).**
-Before the first money goes live, produce and record here:
-
-1. **Disk-storage cost estimate** for the WAL archive + base backups (retention window ×
-   WAL volume; account for both hosts / object-storage pricing). This can change hosting
-   sizing.
-2. **PG performance-degradation assessment** from continuous archiving (write amplification,
-   archive_command latency, backup I/O contention) on the prod-sized instance.
-
-Neither blocks building the plan, but both **must** be completed and reviewed before the
-prod release — surface the numbers to the owner (they may change host settings).
-
-**Tests.** Restore drill on a scratch instance (base + WAL → target timestamp) documented
-and passing. No app-level tests.
-
-**Done-criteria.** WAL archiving live on prod PG; a timed restore verified; cost + perf
-assessment recorded and owner-reviewed; runbook in `deploy/README.md`.
-
-**Notes/risks.** The tg host is weak (1 vCPU) — if the archive lands there, watch
-contention. Migrations stay expand-contract so image rollback remains DB-safe alongside PITR.

-## E5 — Payment intake
-
-**Status:** TODO · **Release 2** · depends on: E0, E1, E2, E4 · mechanics: PAYMENTS §9, §12.
-
-**Goal.** Accept real money on all three rails into the payments domain: order-flow,
-verified provider callbacks, idempotency, the TG bot SQLite outbox, the event dispatcher,
-receipts, and refunds.
-
-**Order-flow & intake (single writer).**
-
-- `POST /api/v1/user/wallet/order` → create `order(pending)` (account/platform/product/
-  expected amount/origin), return the provider-specific launch payload with `order_id`
-  threaded in (Robokassa `InvId` / TG `invoice_payload` / VK `item`).
-- Robokassa + VK **public webhooks**: new edge routes (add to `deploy/caddy/Caddyfile`
-  `@gateway` matcher — or they fall to the landing catch-all), signature/HMAC verified,
-  proxied into a payments intake handler. Match by `order_id`, verify amount, credit
-  (ledger `fund` + balance UPDATE in one tx), mark order `paid`, emit `payment_event`.
-  Idempotent by `(provider, provider_payment_id)`.
-- **Pending sweep:** background reaper expires pending orders after the configured timeout
-  (~30 min). Expiry is cosmetic — a later valid callback still credits (revive/honour).
-
-**TG bot outbox (`platform/telegram/`).**
-
-- The bot receives `successful_payment` (and `pre_checkout_query`) via Bot API. Add a
-  **SQLite** store on the bot's disk: on receipt, persist → ack the Telegram update → forward
-  to a backend payments-intake endpoint (internal, authenticated over the existing reverse
-  mTLS bot-link) → on backend ack, mark `forwarded`. Retries with backoff; re-drive
-  undelivered on restart. Backend intake dedups by `telegram_payment_charge_id`.
-- Provide the invoice creation path (Stars) from the Mini App via the bot as needed.
-
-**Events & notifications.**
-
-- `payment_events` dispatcher: `succeeded`/`failed`/`refunded` → live gRPC stream if the
-  user is connected, else `botlink` push / email relay (existing). "failed" = an active
-  provider decline (not an abandoned pending) surfaced to the user; "succeeded" hook
-  (email/bot message).
-
-**Receipts (§12).** Robokassa self-employed НПД receipt on payment (provider config); VK
-handles Votes tax itself; TG Stars — no receipt.
-
-**Refunds (§9).** ToS non-refundable; admin manual refund (ties to `accountdelete`); external
-`refunded` events honoured — best-effort benefit revoke (never negative; record loss + abuse
-flag if spent), ledger `refund` row. Ledger export-ready (reconciliation not built).
-
-**Tests.**
-
-- unit: signature/HMAC verifiers per rail; order-id matching; idempotency-key dedup.
-- integration: full order→callback→credit per rail; duplicate callback credits once; expired
-  order still honoured on late callback; TG outbox store→forward→ack→cleanup + restart
-  re-drive; refund revoke best-effort/never-negative.
-- UI: purchase flow reaches the provider launch (mock); success/failure surfaced.
-
-**Done-criteria.** A real (sandbox) payment on each rail credits chips exactly once; a
-replayed callback does not double-credit; the TG outbox survives a bot restart mid-flight;
-failed/succeeded events reach the user; refund path exercised. **PITR (E4) armed and the
-cost/perf assessment reviewed before this goes to prod.**
-
-**Notes/risks.** Manual `docker run -p` boot tests fail from the shell — verify the runnable
-artifact via the testcontainers integration suite. Distroless services run UID 65532;
-bind-mounted secrets must be 0644. Edge routes silently fall through if not added to the
-Caddyfile — add a CI probe. The prod rolling deploy skips caddy on config-only changes —
-force-recreate when the Caddyfile changes.

-## E6 — Ads
-
-**Status:** TODO · **Release 2** · depends on: E2 (chips), E5 (rewarded credits via intake) ·
-mechanics: PAYMENTS §10.
-
-**Goal.** VK video ads: the post-move interstitial (frequency-gated) and the rewarded video
-(credits chips via server verify), plus extending the existing banner suppression to
-per-origin.
-
-**Work.**
-
-- **Provider abstraction:** a small ads-network interface (VK impl now) so a future network
-  for other platforms slots in without rework. VK integration via `ui/src/lib/vk.ts`.
-- **Rewarded:** voluntary view → the network's **server verify callback** → payments intake
-  credits chips to the `vk` segment (client not believed, like a payment). On-launch
-  anti-fraud = provider verify only (no own daily cap; abstraction allows later).
-- **Interstitial** (post-move fullscreen), configurable server values (from `payments`
-  config): global per-user cooldown across all games (default 5 min); `vs_ai` 30 min; a hint
-  application triggers a post-move interstitial independently with its own 1-min cooldown;
-  offline banner-only; respect VK's own frequency caps. Cooldown state tracked server-side
-  (per user) or client-mirrored from a server value — pick and document at implementation.
-- **Banner suppression:** extend `ads.Eligible` (`backend/internal/ads/ads.go` :107) to gate
-  on the **origin benefit applicable in the current context** (E2 interface) instead of the
-  single legacy flag. No-ads suppresses banner + interstitial; rewarded never suppressed.
-
-**Tests.**
-
-- unit: cooldown logic (global 5m / vs_ai 30m / hint-trigger 1m independence); rewarded
-  credit path; banner eligibility per context.
-- integration: rewarded verify → credit exactly once (idempotent like a payment).
-- UI: interstitial shows/respects cooldown (mock); rewarded button; no-ads hides banner +
-  interstitial; rewarded still available under no-ads.
-
-**Done-criteria.** VK rewarded credits chips once per verified view; interstitial respects
-all cooldowns incl. the hint trigger; no-ads suppresses banner+interstitial but not
-rewarded; offline shows banner only.
-
-**Notes/risks.** Crypto-payout networks stay rejected. Rewarded-without-payout is pointless —
-only enable where the network pays (VK). Keep the interstitial frequency as server config so
-it tunes without a store release.
-
----
-
-## E7 — Admin & reports
-
-**Status:** TODO · **Release 2** · depends on: E2 (ledger/grant), E5 (payments/refunds) ·
-mechanics: PAYMENTS §11.
-
-**Goal.** The admin console financial surface: per-user report, admin grant UI, manual
-refund UI, ledger export.
-
-**Work (`/_gm`, `backend/internal/server/handlers_admin_console.go` + `adminconsole/`).**
-
-- **Per-user financial panel** on the existing user card (`consoleUserDetail` :343,
-  `UserDetailView`): segment balances, payments, spends, grants, refunds, full history —
-  read from the append-only ledger + materialized cache.
-- **Admin grant** action (mirror the existing `POST /_gm/users/:id/grant-hints`): grant
-  concrete values (no-ads days / hints), **origin picker**, **never chips**; writes an
-  `admin_grant` ledger row (E2 `Grant`).
-- **Manual refund** action: admin-initiated refund of a specific order (ties to the refund
-  path); records a `refund` ledger row; best-effort benefit revoke.
-- **Ledger export**: CSV/JSON export of the ledger for tax reporting + future Robokassa
-  reconciliation (export-ready schema; reconciliation itself not built).
-- Auth unchanged: gateway Basic-Auth in front of `/_gm` + backend same-origin CSRF on POSTs.
-
-**Tests.**
-
-- unit: report view assembly; grant refuses chips; export shape.
-- integration: grant/refund write correct ledger rows; report reflects balances+history.
-
-**Done-criteria.** An operator can see a user's full financial picture, grant concrete
-values (origin-picked, never chips), issue a manual refund, and export the ledger.
-
-**Notes/risks.** `/_gm` per-user detail already surfaces `PaidAccount`/`HintBalance` — replace
-those with the segmented view as the legacy columns retire.
-
----
-
-## E8 — Guest limits
-
-**Status:** TODO · **standalone** (game-behaviour change; can run in parallel) · depends on:
-none · mechanics: PAYMENTS §6.
-
-**Goal.** A registration funnel: cap what a guest can do, enforced **server-side** (today the
-gating is UI-only).
-
-**Finding (verified).** The friend/invitation paths do **not** check `is_guest` on the
-server — only the UI hides them: `social/friends.go:50` `SendFriendRequest`,
-`robotfriends.go:41` `RequestInGame`, `friendcodes.go:67` `RedeemFriendCode`,
-`lobby/invitations.go:208` `CreateInvitation`. A guest with a valid `X-User-ID` can call them
-in the UI's stead.
-
-**Work.**
-
-- **Server guest gate** on friend-request / redeem-code / invitation-create: refuse when the
-  caller `is_guest` (add an `ErrGuestForbidden`-style guard, as `feedback` already has).
-- **Active-game limits** for guests: at most **1 random-opponent game + 1 vs_ai** concurrently
-  (enforce on game/invitation creation in `lobby`/`game`; today no such limit exists).
-- Keep the existing UI gating; this adds the server as the source of truth.
-
-**Tests.**
-
-- integration: guest is refused friend/redeem/invitation server-side; guest blocked from a
-  2nd random / 2nd vs_ai; durable account unaffected.
-- UI: guest sees the funnel (existing hides + any new messaging).
-
-**Done-criteria.** Guests are server-limited to 1 random + 1 vs_ai and cannot friend/invite;
-durable accounts unchanged; regression that this does not break existing durable flows.
-
-**Notes/risks.** This changes existing game behaviour — its own tests, its own PR, no
-mixed-in payments changes. Decide whether a guest may finish an already-started game (limit
-on creation, not mid-game) at implementation and record it here.
-
----
-
-## E9 — Tournament fee (future)
-
-**Status:** TODO · **future** · depends on: E0 (atom provisioned), tournament feature ·
-mechanics: PAYMENTS §5, §7.
-
-**Goal.** Charge a chip entry fee for tournaments. The `tournament` atom + a catalog product
-are provisioned in E0/E7; the spend mechanic reuses E2 (`Spend`). The actual tournament
-feature and its coupling to entry are out of scope until the tournament feature exists.
-
-**Done-criteria.** Deferred — revisit when tournaments are built.
-
----
-
-## Verification & CI (all stages)
-
-- Per-stage tests at the layers above; **compliance-gate regression is mandatory** (a
-  `direct` benefit must never activate inside VK/TG) and runs from E2 onward.
-- Local full verification before every push: `go build/vet ./backend/... && gofmt -l .`,
-  integration (`-tags=integration` + DAWG sibling + Ryuk-off), `pnpm -C ui check/test:unit/
-  build`, Playwright mock e2e, codegen (`make -C pkg proto fbs`, `pnpm -C ui codegen`).
-- Contour: each PR into `development` auto-deploys the test contour; owner does visual sign-
-  off there (not local). Keep a multi-PR batch a linear stack (one shared contour,
-  last-deploy-wins).
-- Prod (Release 2): expand-contract migrations only (image rollback DB-safe); PITR armed +
-  the E4 cost/perf assessment reviewed **before** the first money; new edge routes added to
-  the Caddyfile with a CI probe; caddy force-recreated on config-only changes.
-- Release framing: **shipped docs/code/commits/PRs carry no stage ids** — finalize copy for
-  the release, not the plan.

--- Payments data foundation: a self-contained `payments` schema for the in-game
--- currency, wallets, benefits, catalog, orders and the append-only operations
--- ledger. Nothing is wired to real money yet — this is the substrate the rest of
--- the payments domain builds on. Mechanics live in docs/PAYMENTS.md.
---
--- Isolation. The schema is confined to a dedicated NOLOGIN role that holds ALL
--- privileges on `payments.*` and none on `backend.*`; the backend application
--- keeps its single (superuser) pool, so the DB grants are a stepping-stone to a
--- future separate login/process rather than a runtime wall. The runtime wall is
--- code-level: only the payments package reaches these tables (an import-boundary
--- test guards it). There is deliberately NO cross-schema foreign key to
--- `backend.accounts`: `account_id` is a plain uuid, kept referentially honest in
--- code and joined to the tombstoned account / retained-identities dossier by the
--- stable account id — which keeps the domain extractable into its own database.
---
--- The ledger is append-only, enforced by a trigger (a superuser bypasses table
--- privileges, so a REVOKE would not bind the application). Money is stored as an
--- integer amount in the currency's minor units (RUB kopecks; Votes/Stars/chips
--- are whole units, scale 1), never a float — integer-currency integrality is
--- therefore structural.
---
--- Legacy note: backend.accounts.hint_balance and backend.accounts.paid_account
--- are superseded by the segmented model here and are DEPRECATED. They are NOT
--- dropped in this expand phase — reads still use them until the currency core
--- flips them, and the DROP is a later contract-phase migration (image rollback
--- must stay DB-safe). Neither was ever set in production.
---
--- Expand-contract: everything here is additive in its own schema, so a backend
--- image rollback stays DB-safe (older code simply ignores the new schema).

-adoption and profile fetch that would otherwise hang with no network, and lands straight in the

-# PAYMENTS — monetization mechanics
-
-Authoritative specification of the monetization domain: the in-game currency, wallets,
-benefits, store-compliance rules, payment intake, ads, catalog, ledger, and reporting.
-English is authoritative; [`PAYMENTS_ru.md`](PAYMENTS_ru.md) mirrors it in plain Russian
-(mirror every point edit in the same PR, like `FUNCTIONAL.md`/`FUNCTIONAL_ru.md`).
-
-Read this before changing any payments behaviour. The technical implementation plan lives
-in [`../PLAN.md`](../PLAN.md).
-
-> Status: specification approved; implementation staged (see `PLAN.md`). Nothing here is
-> live yet.
-
-## 1. Overview
-
-The game earns through two orthogonal channels:
-
-- **Purchases** of the in-game currency **Фишка** (chips) with real money, then spending
-  chips on **values** (benefits).
-- **Ads** — a rewarded video tops chips up; an interstitial and a house banner monetize by
-  impression.
-
-The currency is **two-tier**:
-
-```
-money (VK Votes / TG Stars / RUB via Robokassa)  ─┐
-                                                  ├─►  Фишки (chips)  ──►  values
-rewarded ad view                                 ─┘                         (no-ads, hints,
-                                                                             tournament fee)
-```
-
-Chips are the single storefront unit. Money and rewarded views **fund** chips; chips
-**buy** values. There is no path that spends money directly on a value — always through
-chips.
-
-## 2. Currency model
-
-**One chip is one chip everywhere** — the unit is uniform. The difference between payment
-methods lives entirely in the **purchase rate**: a chip pack costs *X* Votes / *Y* Stars /
-*Z* RUB, and the rate absorbs each store's commission. Value prices are fixed **in chips**
-and identical across methods.
-
-The chip balance is **segmented by `source`** — the platform where the chips were funded:
-
-| `source`   | Funded by                        |
-|------------|----------------------------------|
-| `vk`       | VK Votes purchase, VK rewarded ad |
-| `telegram` | TG Stars purchase                |
-| `direct`   | Robokassa purchase (web / native)|
-
-A single account holds all three segments simultaneously: `balance = (account_id, source)`,
-up to three rows — a row is materialised lazily on the segment's first funding, and an absent
-segment reads as zero. Segmentation is **not** per-identity — see §6.
-
-Why segmented, not one pooled balance: store rules forbid activating value that was paid
-for outside the store's own cash desk. Chips funded inside VK (Votes) may only be spent in
-the VK context; Stars only inside Telegram; Robokassa-funded (`direct`) chips only outside
-the stores. See §4.
-
-## 3. Three operations, kept distinct
-
-Do not conflate these — they use different keys:
-
-1. **Fund chips** — money/ad → chip `source` segment, keyed by the **execution context**.
-2. **Spend chips = buy a value** — segment → benefit, keyed by context with the gate (§4).
-   This is where a benefit is **born** and stamped with its `origin`.
-3. **Apply a benefit** over time (e.g. "no-ads until *T*") — governed by the origin rule
-   (§5).
-
-`source` (where chips were funded) and `origin` (where a value was bought) share the same
-value set `{vk, telegram, direct}` but mean different things. On the web they can diverge:
-web spending may draw `vk` chips (`source=vk`) into a `direct` purchase (`origin=direct`).
-
-## 4. Store-compliance gate
-
-The compliance wall is **one-directional**. The dangerous direction — activating externally
-paid value *inside* a store wrapper — is blocked; the safe direction (a store benefit
-leaking out to the open web) is allowed.
-
-**Spend context → which segments/benefits are usable:**
-
-| Execution context   | Spendable chip segments | Spend priority     |
-|---------------------|-------------------------|--------------------|
-| Inside VK (Android) | `vk`                    | —                  |
-| Inside VK (iOS)     | none — frozen (view only)| —                 |
-| Inside Telegram     | `telegram`              | —                  |
-| Web / native (Direct)| `direct` + `vk` + `telegram` | direct → vk → tg |
-
-- Inside VK/TG only the same-named segment is usable; everything else (chiefly `direct`) is
-  invisible-as-spendable there.
-- On the web the store has no jurisdiction, so all attached segments are spendable, drained
-  by priority direct → vk → tg.
-- **VK iOS** is frozen for spending (Apple forbids spending virtual currency on digital
-  goods outside IAP inside VK on iOS): the balance is shown as a number, but no purchase or
-  spend is possible. A previously bought benefit still *applies* there.
-
-The account is **single** (identities merge, one profile/friends/stats). The gate is
-**logical**: in a VK/TG context the server activates only the same-named segment. It rests
-on a **trusted platform signal** (§8) — the client is never believed. When the platform
-cannot be trusted, the gate is **fail-closed**: spends/purchases are denied, view only.
-
-### One-directional benefit application
-
-A benefit carries `origin` = the **purchase context** (not "what it was paid with"). Buying
-on the web with `vk` chips still yields `origin=direct`.
-
-| `origin`         | Where the benefit applies                          |
-|------------------|----------------------------------------------------|
-| `vk` / `telegram`| **Everywhere** — inside its store *and* out on web/native |
-| `direct`         | **Only** web/native — never inside VK/TG (= store ban) |
-
-Before a web spend draws `vk`/`telegram` chips, the UI **warns** the user that the value
-will be available here (web/native) only, because of VK/TG restrictions.
-
-## 5. Benefits
-
-Three distinct entities, do not merge:
-
-- **Chips** — currency. Segment by `source`.
-- **Hints** — consumable, bought with chips. Segment by `origin`. Spent one-per-hint in
-  online games; `vs_ai` hints stay free/unlimited (30-min idle gate, not counted). A hint
-  spent in a game is drawn from an `origin` applicable to the current context (same
-  one-directional relaxation as above).
-- **No-ads** — a duration benefit, bought with chips. Segment by `origin`.
-
-**No-ads stacking.** Buying a term extends `paid_until[origin] += term` from
-`max(now, current end)` — the remainder is never lost ("terms add up"). **Forever** is a
-separate perpetual flag that overrides terms. "Ads off in context *P*" ⇔ some `origin`
-applicable in *P* has `paid_until > now` (on the web take the max over direct/vk/tg; in VK
-only vk; in TG only tg).
-
-**What no-ads suppresses:** the top banner **and** the post-move fullscreen interstitial.
-The voluntary **rewarded** view (for chips) is never suppressed — it is the user's choice.
-
-**Tournament fee** — a future value type; the atom is provisioned but the mechanic ships
-later.
-
-## 6. Wallet lifecycle
-
-**Segment availability rule.** A segment is spendable ⇔ the account has an identity of that
-`source` (for `direct`: a durable identity/email). This makes unlink/merge fall out
-naturally.
-
-**Unlink (vk/tg).** Allowed even with a non-zero balance/active benefit. The segment is not
-burned — it **sleeps** (no identity ⇒ unavailable in VK *and*, lacking the attachment,
-unavailable as an attached web segment); re-linking wakes it. The user is warned before
-unlinking ("N chips will be unavailable until you re-link"). The last identity cannot be
-unlinked (existing `ErrLastIdentity`).
-
-**Merge.** Segments and benefits merge **by origin**: same-origin segments add (chips sum,
-benefit terms extend per origin), different origins coexist. This extends the current
-account-merge (`hint_balance +=`, `paid_account OR=`) so origin is preserved and nothing
-leaks across platforms.
-
-**Guest.** A guest account has **no wallet at all** — the Wallet section is hidden, no
-purchases, no balance, by design. Balances belong only to durable accounts. The guest
-reaper therefore deletes guests freely (no money can exist there). In `direct`, email is
-required **before the first purchase** as a recovery anchor (in VK/TG the vk/tg identity is
-already the anchor); the existing email flow (request code → confirm → clear guest →
-durable) is reused.
-
-## 7. Catalog and pricing
-
-The catalog is **configurable** — products, prices, purchase rates, and rewarded payout
-live in the database and are edited in the admin console, no release required.
-
-- **Base values (atoms):** chips, hints, no-ads days, tournament entry.
-- **Product = a set of atoms + a price.** Sold singly or as a combo (e.g. "250 hints + 30
-  no-ads days").
-- **Chip pack** (funds chips) — priced **per method** (multi-currency Votes/Stars/RUB) as a
-  single product.
-- **Value** (bought with chips) — priced **in chips** (uniform across methods).
-
-**Deactivation, not deletion.** Products are soft-deleted (deactivated). A completed
-purchase stores a **snapshot** of what was sold (atom composition + price at the time) into
-an archive, so history/receipts/tax are independent of later catalog edits.
-
-## 8. Trusted platform signal
-
-The gate (§4) needs a **trusted, unforgeable** platform context on the server. The client is
-never the source of truth.
-
-- The platform is a **property of the session**, captured when the session is created. VK and
-  Telegram wrappers re-mint (and so re-validate the launch signature — VK launch-params `sign`
-  / Telegram `initData`) on **every cold start**, so their platform is re-confirmed each launch;
-  a `direct` session captures it once, established by the fact of a web/native session's creation
-  (no external signer, and none needed — reaching vk/tg segments in a direct context still
-  requires a real attachment, §6).
-- The platform carries **kind** (`vk`/`telegram`/`direct`) **plus subtype**
-  (`ios`/`android`/`web`). `kind` is always trusted — the server derives it from the validated
-  launch, never a client field. The **subtype is trusted only for VK**: it rides inside the
-  signed launch parameters, which is what makes the **VK iOS freeze** enforceable; for Telegram
-  and direct the subtype is client-reported and best-effort, so the gate never keys off it.
-- The gateway resolves the session and passes `platform` to the backend (alongside the existing
-  `X-User-ID`), sourced from the session — never the client request body.
-- **Fail-closed:** an untrusted platform — a session with no recorded platform, one predating
-  this feature or one the gateway could not attribute — denies spends/purchases and applying any
-  foreign origin (view only). A VK/TG session recovers on its next cold-start re-mint; a reused
-  direct/email session on re-login.
-
-## 9. Payment intake
-
-**Server callback only.** Chips are credited solely on a **verified** (signature/HMAC)
-provider callback — Robokassa webhook / TG `successful_payment` / VK callback. A client "I
-paid" is ignored.
-
-**Single writer.** One payments domain is the only writer of the ledger. Public webhooks
-(Robokassa/VK) terminate at the edge (Caddy/gateway) and proxy into payments; TG
-`successful_payment` reaches the bot, which forwards into payments. One place credits and
-dedupes.
-
-**Order-flow.** The server pre-creates an `order(pending)` with account / platform / pack /
-expected amount / origin. The `order_id` is threaded to the provider (Robokassa `InvId` / TG
-`invoice_payload` / VK `item` — confirm the exact VK field at integration). The callback
-matches by `order_id` (never by amount, so equal-amount collisions cannot happen), verifies
-the amount, credits, marks `paid`. **Idempotency:** dedup by `(provider, provider_payment_id)`.
-
-**Pending is invisible** to the user; it auto-expires on a timeout (~30 min, DB hygiene). A
-valid callback is **always** honoured, even on an expired order (`expired` ≠ cancellation —
-the money is real, the chips are owed). The user sees only successful purchases.
-
-**TG bot outbox.** `successful_payment` reaches the bot only (Bot API, not the Mini App), and
-the bot host is weak and can lose connectivity, so the bot is a durable link. Store-and-
-forward on **SQLite** on the bot's disk: receive → store → ack the Telegram update → forward
-to payments (idempotent, dedup by `telegram_payment_charge_id`) → ack → mark `forwarded`.
-Retries with backoff; re-drives undelivered on restart. At-least-once delivery + idempotent
-intake = credited exactly once.
-
-**Events.** The payments domain writes `payment_events` (succeeded / failed / refunded); a
-dispatcher fans out over channels — the live gRPC stream if the user is in-app, else the
-existing `botlink` push / email relay. "Payment failed" (an **active** provider decline, not
-an abandoned pending) is surfaced to the user; "payment succeeded" is a hook (email / bot
-message).
-
-**Refunds.** ToS is **non-refundable** — we do not offer refunds to the user. An admin may
-issue a **manual** refund (edge case: a user demands one shortly after paying / closes their
-account — tie into `accountdelete`, which already preserves messages). **External** refunds
-(chargeback / store decision / TG / VK) are honoured: the system takes the `refunded` event,
-**best-effort** revokes the benefit (never going negative; if chips were already spent, it
-records the loss + an abuse flag), and writes to the ledger. The ledger is **export-ready**
-for future tax reporting and Robokassa reconciliation (reconciliation itself is not built
-yet; the schema stays compatible).
-
-## 10. Ads
-
-**Launch scope: VK only** for video (rewarded payout in RUB, ОРД automatic, API ready).
-web/native/TG keep the existing house **text banner** only; video is deferred until a
-ruble-paying in-app network exists. The ad provider is behind an **abstraction** so a future
-network for other platforms slots in without rework. Crypto-payout networks (AdsGram/AdMob)
-are rejected — no legal ruble income for a self-employed (НПД) developer.
-
-**Rewarded** (voluntary video for chips) credits chips through payments on the network's
-**server verify callback** (client not believed, like a payment). On-launch anti-fraud is
-the provider's verify only (no own daily cap yet; the abstraction allows adding caps later).
-
-**Interstitial** (post-move fullscreen), configurable server-side values:
-
-- Global cooldown **per user, across all games**, default **5 min**.
-- **`vs_ai` — 30 min** (aligned with the hint cooldown, so it does not scare casual players).
-- Applying a **hint** triggers a post-move interstitial **independently** of the main
-  cooldown, with its own **1-min** cooldown.
-- Offline — banner only.
-- Respect VK's own frequency caps.
-
-**No ads offline** beyond the house banner. The `no-ads` benefit suppresses the banner via
-the existing `ads.Eligible` (`backend/internal/ads/ads.go`), which is extended to gate on
-the **origin benefit applicable in the current context** rather than one global flag.
-
-## 11. Admin, audit, reporting
-
-**Append-only ledger + materialized balance.** The operations ledger is **INSERT-only**
-(never UPDATE/DELETE — full audit). Segment balances `(account, source)` and benefits
-`(account, origin)` are a fast **materialized** cache, updated **in the same transaction** as
-the ledger write, and recomputable from the ledger for reconciliation.
-
-**Admin rewards.** An admin grants **concrete values only** (no-ads / hints) — **never
-chips** (a gifted currency balance = a store cash-desk bypass). The admin **picks the
-origin** at grant time (compliance is on them: `origin=vk` point-wise/low-volume = low risk,
-`origin=direct` = safe). A grant is a ledger transaction of type `admin_grant`, price 0
-chips — full audit of rewards.
-
-**Per-user financial report** in the admin console `/_gm` — segment balances, payments,
-spends, grants, refunds, full history — as an extension of the existing user card
-(`UserDetailView`, `handlers_admin_console.go`). Plus a ledger export.
-
-## 12. Taxes and compliance
-
-Receipts are automatic **through the provider**, and differ by rail:
-
-- **Robokassa** (direct) — self-employed НПД receipt on payment.
-- **VK** — VK processes Votes through the tax authority itself; nothing to do.
-- **TG Stars** — no tax side (for a RU self-employed, Stars are not legally withdrawable = not
-  НПД income; accepted, no receipt issued).
-
-**ОРД** (ad marking) for VK ads is handled on VK's side. (Not legal advice — the owner
-confirms the exact НПД scheme with a tax advisor.)
-
-## 13. Distribution (native Android)
-
-- **RuStore** — Robokassa/external gate allowed (0%); native = clean `direct` context.
-- **Google Play** — direct purchases are **hidden**; the Wallet shows a stub ("install the
-  RuStore build to make purchases"). Rewarded ads and spending already-earned chips still
-  work. Confirm Google's current in-app-currency rules before the GP release.
-
-## 14. Data model (schema `payments`)
-
-The payments domain lives in its **own schema `payments`** in the shared Postgres instance,
-with its own DB role (rights limited to `payments`) and a domain package behind a hard
-interface. There is **no cross-schema foreign key** to `backend.accounts` — an account id is a
-plain value here, kept consistent in code and joined to the tombstoned account /
-retained-identities dossier by the stable id. That keeps the chip↔benefit spend atomic
-**within `payments`** and the domain extractable into its own database. Durability is **PITR**
-(continuous WAL archive), independent of DB topology.
-
-Core tables (final names/columns fixed in `PLAN.md`):
-
-- **ledger** — append-only operations: fund / spend / `admin_grant` / refund; `(provider,
-  provider_payment_id)` unique for idempotency; export-ready.
-- **balances** — materialized `(account_id, source) → chips`.
-- **benefits** — materialized `(account_id, origin)` → no-ads `paid_until`/`forever` +
-  hints count.
-- **catalog** — atoms + products (soft-deletable), per-method prices, chip-purchase rates,
-  rewarded payout.
-- **orders** — pending purchases, `order_id`, expected amount, origin, status
-  (pending/paid/expired).
-- **payment_events** — succeeded/failed/refunded for the dispatcher.
-
-Legacy `accounts.hint_balance` and `accounts.paid_account` are **deprecated** in favour of the
-segmented model and dropped in a later **contract-phase** migration (expand-contract, after the
-currency core flips reads and Release 2 — image rollback stays DB-safe); neither was ever set in
-prod (no purchase flow existed), so legacy values are zeroed.

-## 15. Glossary
-
-- **Фишка / chip** — the in-game currency; uniform unit, segmented by `source`.
-- **source** — where chips were funded (`vk`/`telegram`/`direct`).
-- **origin** — where a value was bought; governs where the benefit applies.
-- **value / benefit** — what chips buy (no-ads, hints, tournament fee).
-- **gate** — the one-directional store-compliance rule (§4).

-# PAYMENTS — механики монетизации
-
-Русское зеркало [`PAYMENTS.md`](PAYMENTS.md) (английская версия — основная). Описывает
-домен монетизации: игровую валюту, кошельки, ценности, правила комплаенса сторов, приём
-платежей, рекламу, каталог, журнал операций и отчёты. Каждую правку `PAYMENTS.md` зеркалим
-сюда в том же PR (как `FUNCTIONAL.md`/`FUNCTIONAL_ru.md`).
-
-Читать перед любым изменением платёжного поведения. Технический план внедрения —
-[`../PLAN.md`](../PLAN.md).
-
-> Статус: спецификация утверждена; внедрение поэтапно (см. `PLAN.md`). В проде пока ничего
-> из этого нет.
-
-## 1. Обзор
-
-Игра зарабатывает двумя независимыми каналами:
-
-- **Покупки** игровой валюты **«Фишка»** за реальные деньги, затем трата Фишек на
-  **ценности** (бенефиты).
-- **Реклама** — ролик за награду пополняет Фишки; полноэкранный ролик и наш баннер
-  зарабатывают показами.
-
-Валюта **двухуровневая**:
-
-```
-деньги (Голоса VK / Stars TG / рубли через Robokassa)  ─┐
-                                                        ├─►  Фишки  ──►  ценности
-просмотр ролика за награду                             ─┘                (без рекламы,
-                                                                          подсказки,
-                                                                          турнирный взнос)
-```
-
-Фишки — единая единица витрины. Деньги и просмотры **пополняют** Фишки; Фишки **покупают**
-ценности. Прямой оплаты ценности деньгами нет — всегда через Фишки.
-
-## 2. Модель валюты
-
-**Одна Фишка равна одной Фишке везде** — единица единая. Разница между методами оплаты
-целиком в **курсе покупки**: пакет Фишек стоит *X* Голосов / *Y* Stars / *Z* рублей, и курс
-учитывает комиссию каждого стора. Цены ценностей фиксированы **в Фишках** и одинаковы для
-всех методов.
-
-Баланс Фишек **сегментирован по «источнику» (`source`)** — платформе, где Фишки пополнены:
-
-| `source`   | Чем пополняется                    |
-|------------|------------------------------------|
-| `vk`       | Покупка за Голоса VK, ролик за награду в VK |
-| `telegram` | Покупка за Stars TG                |
-| `direct`   | Покупка через Robokassa (web / native) |
-
-Один аккаунт держит все три сегмента одновременно: `баланс = (account_id, source)`, до трёх
-записей — запись материализуется лениво при первом пополнении сегмента, отсутствующий сегмент
-читается как ноль. Сегментация **не** по привязке (identity) — см. §6.
-
-Почему сегментировано, а не один общий баланс: правила сторов запрещают активировать
-ценность, оплаченную мимо их кассы. Фишки, пополненные внутри VK (Голоса), тратятся только
-в контексте VK; Stars — только внутри Telegram; Фишки от Robokassa (`direct`) — только вне
-сторов. См. §4.
-
-## 3. Три операции, которые нельзя путать
-
-Не смешивать — у них разные ключи:
-
-1. **Пополнить Фишки** — деньги/реклама → сегмент `source` Фишек, по **контексту
-   исполнения**.
-2. **Потратить Фишки = купить ценность** — сегмент → бенефит, по контексту с гейтом (§4).
-   Здесь бенефит **рождается** и помечается своим `origin`.
-3. **Применить бенефит** во времени (напр. «без рекламы до *T*») — по правилу `origin`
-   (§5).
-
-`source` (где пополнены Фишки) и `origin` (где куплена ценность) используют одно множество
-значений `{vk, telegram, direct}`, но значат разное. В вебе они расходятся: покупка в вебе
-может списать `vk`-Фишки (`source=vk`) в `direct`-покупку (`origin=direct`).
-
-## 4. Гейт комплаенса сторов
-
-Стена комплаенса **односторонняя**. Опасное направление — активация оплаченной снаружи
-ценности *внутри* обёртки стора — заблокировано; безопасное (бенефит стора действует
-наружу, в открытом вебе) — разрешено.
-
-**Контекст траты → какие сегменты/бенефиты доступны:**
-
-| Контекст исполнения  | Тратимые сегменты Фишек   | Приоритет траты    |
-|----------------------|---------------------------|--------------------|
-| Внутри VK (Android)  | `vk`                      | —                  |
-| Внутри VK (iOS)      | нет — заморожено (только просмотр) | —          |
-| Внутри Telegram      | `telegram`                | —                  |
-| Web / native (Direct)| `direct` + `vk` + `telegram` | direct → vk → tg |
-
-- Внутри VK/TG доступен только одноимённый сегмент; всё остальное (в первую очередь
-  `direct`) там невидимо как тратимое.
-- В вебе у стора нет юрисдикции, поэтому доступны все привязанные сегменты, списываются по
-  приоритету direct → vk → tg.
-- **VK iOS** заморожен для траты (Apple запрещает тратить виртуальную валюту на цифровые
-  товары мимо IAP внутри VK на iOS): баланс показывается числом, но покупка/трата
-  невозможны. Ранее купленный бенефит там всё равно *действует*.
-
-Аккаунт **единый** (привязки сливаются, один профиль/друзья/статистика). Гейт
-**логический**: в контексте VK/TG сервер активирует только одноимённый сегмент. Держится на
-**доверенном сигнале платформы** (§8) — клиенту не верим. Когда платформу нельзя доверенно
-установить, гейт **fail-closed**: траты/покупки запрещены, только просмотр.
-
-### Одностороннее применение бенефита
-
-Бенефит несёт `origin` = **контекст покупки** (не «чем оплачено»). Покупка в вебе за
-`vk`-Фишки всё равно даёт `origin=direct`.
-
-| `origin`         | Где действует бенефит                              |
-|------------------|----------------------------------------------------|
-| `vk` / `telegram`| **Везде** — внутри своего стора *и* наружу в web/native |
-| `direct`         | **Только** web/native — никогда внутри VK/TG (= бан) |
-
-Перед тратой в вебе `vk`/`telegram`-Фишек интерфейс **предупреждает**, что ценность будет
-доступна только здесь (web/native) из-за ограничений VK/TG.
-
-## 5. Ценности
-
-Три разные сущности, не смешивать:
-
-- **Фишки** — валюта. Сегмент по `source`.
-- **Подсказки** — расходник, покупается за Фишки. Сегмент по `origin`. Тратятся по одной в
-  онлайн-играх; в `vs_ai` подсказки бесплатны/безлимитны (30-мин кулдаун, не в счёт).
-  Подсказка в игре списывается из `origin`, применимого в текущем контексте (то же
-  одностороннее послабление).
-- **Без рекламы** — срок-бенефит, покупается за Фишки. Сегмент по `origin`.
-
-**Складывание «без рекламы».** Покупка срока продлевает `paid_until[origin] += срок` от
-`max(сейчас, текущий конец)` — остаток не теряется («сроки плюсуются»). **Навсегда** —
-отдельный вечный флаг, перекрывает сроки. «Реклама выключена в контексте *P*» ⇔ есть
-применимый в *P* `origin` с `paid_until > сейчас` (в вебе берём максимум по direct/vk/tg; в
-VK только vk; в TG только tg).
-
-**Что гасит «без рекламы»:** верхний баннер **и** полноэкранный ролик после хода.
-Добровольный **ролик за награду** (за Фишки) не гасится — это выбор пользователя.
-
-**Турнирный взнос** — будущий тип ценности; атом заложен, механика позже.
-
-## 6. Жизненный цикл кошелька
-
-**Правило доступности сегмента.** Сегмент тратим ⇔ на аккаунте есть привязка этого
-`source` (для `direct` — устойчивая привязка/email). Отсюда unlink/мерж выводятся
-естественно.
-
-**Отвязка (vk/tg).** Разрешена даже при ненулевом балансе/активном бенефите. Сегмент не
-сжигается — он **засыпает** (нет привязки ⇒ недоступен в VK *и*, без привязки, недоступен
-как подтянутый веб-сегмент); повторная привязка будит. Перед отвязкой предупреждение
-(«N Фишек станут недоступны до повторной привязки»). Последнюю привязку отвязать нельзя
-(существующий `ErrLastIdentity`).
-
-**Мерж.** Сегменты и бенефиты сливаются **по origin**: одноимённые складываются (Фишки
-суммируются, сроки бенефита продлеваются по origin), разные сосуществуют. Это расширяет
-текущий мерж аккаунтов (`hint_balance +=`, `paid_account OR=`), так что origin сохраняется и
-ничего не протекает между платформами.
-
-**Гость.** У гостевого аккаунта **вообще нет кошелька** — раздел «Кошелёк» скрыт, покупок
-нет, баланса нет, by design. Балансы — только у durable-аккаунтов. Поэтому чистильщик
-гостей удаляет их свободно (денег там быть не может). В `direct` email обязателен **перед
-первой покупкой** как якорь восстановления (в VK/TG якорь — сама vk/tg-привязка);
-переиспользуем существующий флоу email (запрос кода → подтверждение → снятие флага гостя →
-durable).
-
-## 7. Каталог и цены
-
-Каталог **конфигурируемый** — продукты, цены, курсы покупки и награда за ролик живут в базе
-и правятся в админке, без релиза.
-
-- **Базовые ценности (атомы):** Фишки, подсказки, дни без рекламы, участие в турнире.
-- **Продукт = набор атомов + цена.** Продаётся по одной или комбо (напр. «250 подсказок +
-  30 дней без рекламы»).
-- **Пакет Фишек** (пополняет Фишки) — цена **per-метод** (мультивалютная Голоса/Stars/руб)
-  одним продуктом.
-- **Ценность** (за Фишки) — цена **в Фишках** (единая для всех методов).
-
-**Деактивация, не удаление.** Продукты деактивируются (soft-delete). Состоявшаяся покупка
-хранит **снимок** проданного (состав атомов + цена на момент) в архиве, чтобы
-история/чеки/налоги не зависели от последующих правок каталога.
-
-## 8. Доверенный сигнал платформы
-
-Гейту (§4) нужен **доверенный, неподделываемый** контекст платформы на сервере. Клиент —
-никогда не источник правды.
-
-- Платформа — **свойство сессии**, фиксируется при создании сессии. Обёртки VK и Telegram
-  пересоздают сессию (и потому заново проверяют подпись запуска — VK launch-params `sign` /
-  Telegram `initData`) на **каждом холодном старте**, поэтому их платформа переподтверждается
-  при каждом запуске; `direct`-сессия фиксирует платформу один раз, самим фактом создания
-  веб/native-сессии (внешней подписи нет и не нужно — доступ к vk/tg-сегментам в direct-контексте
-  всё равно требует реальной привязки, §6).
-- Платформа несёт **kind** (`vk`/`telegram`/`direct`) **плюс подтип** (`ios`/`android`/`web`).
-  `kind` доверенный всегда — сервер выводит его из проверенного запуска, не из клиентского поля.
-  **Подтип доверенный только у VK**: он лежит внутри подписанных параметров запуска, что и делает
-  **заморозку VK iOS** выполнимой; у Telegram и direct подтип сообщает клиент, он best-effort, и
-  гейт на него не опирается.
-- Гейтвей резолвит сессию и передаёт `platform` в бэкенд (рядом с существующим `X-User-ID`),
-  беря его из сессии — не из тела клиентского запроса.
-- **Fail-closed:** недоверенная платформа — сессия без записанной платформы, созданная до этой
-  функции или которую гейтвей не смог атрибутировать — запрещает траты/покупки и применение
-  любого чужого origin (только просмотр). VK/TG-сессия восстанавливается на следующем холодном
-  старте (пересоздание), переиспользуемая direct/email-сессия — при повторном входе.
-
-## 9. Приём платежей
-
-**Только серверный колбэк провайдера.** Фишки начисляются лишь по **проверенному**
-(подпись/HMAC) серверному колбэку — Robokassa webhook / TG `successful_payment` / VK
-callback. Клиентское «я оплатил» игнорируется.
-
-**Единственный писатель.** Один платёжный домен — единственный, кто пишет в журнал операций.
-Публичные вебхуки (Robokassa/VK) терминируются на краю (Caddy/gateway) и проксируются в
-платёжный домен; TG `successful_payment` приходит боту, тот форвардит в платёжный домен.
-Одно место начисляет и защищает от повторов.
-
-**Флоу заказа.** Сервер заранее создаёт `order(pending)` с account / платформой / пакетом /
-ожидаемой суммой / origin. `order_id` прокидывается провайдеру (Robokassa `InvId` / TG
-`invoice_payload` / VK `item` — точную форму VK уточнить при интеграции). Колбэк матчится по
-`order_id` (никогда по сумме, поэтому коллизии одинаковых сумм невозможны), сверяет сумму,
-начисляет, помечает `paid`. **Защита от повторов:** дедуп по `(провайдер,
-provider_payment_id)`.
-
-**Pending невидим** пользователю; авто-истекает по таймауту (~30 мин, гигиена базы).
-Валидный колбэк исполняется **всегда**, даже на истёкшем заказе (`expired` ≠ отмена —
-деньги реальны, Фишки должны быть выданы). Пользователь видит только успешные покупки.
-
-**Outbox TG-бота.** `successful_payment` приходит только боту (Bot API, не Mini App), а
-хост бота слабый и может терять связь, поэтому бот — durable-звено. Store-and-forward на
-**SQLite** на диске бота: получил → сохранил → подтвердил апдейт Telegram → форвардит в
-платёжный домен (идемпотентно, дедуп по `telegram_payment_charge_id`) → ack → пометил
-`forwarded`. Ретраи с backoff; дореталивает недоставленное при рестарте. Доставка
-at-least-once + идемпотентный приём = начисление ровно один раз.
-
-**События.** Платёжный домен пишет `payment_events` (succeeded / failed / refunded);
-диспетчер рассылает по каналам — live gRPC-стрим, если пользователь в аппе, иначе
-существующий пуш `botlink` / email. «Оплата не прошла» (**активный** отказ провайдера, не
-брошенный pending) доводится до пользователя; «оплата прошла» — хук (письмо / сообщение в
-бота).
-
-**Возвраты.** ToS — **невозвратно**, пользователю возврат не предлагаем. Админ может сделать
-**ручной** возврат (крайний случай: пользователь требует вскоре после оплаты / закрывает
-аккаунт — связано с `accountdelete`, где уже сохраняются сообщения). **Внешние** возвраты
-(чарджбек / решение стора / TG / VK) обрабатываются: система принимает событие `refunded`,
-**по возможности** отзывает бенефит (в минус не уходим; если Фишки уже потрачены —
-фиксирует убыток + флаг защиты от злоупотреблений), пишет в журнал. Журнал операций
-**спроектирован экспортопригодным** для будущей налоговой отчётности и сверки с Robokassa
-(саму сверку пока не строим; схема остаётся совместимой).
-
-## 10. Реклама
-
-**Охват на старте: только VK** для видео (награда в рублях, ОРД автоматом, API готов).
-web/native/TG держат только существующий наш **текст-баннер**; видео отложено до появления
-рублёвой in-app сети. Рекламный провайдер за **абстракцией**, чтобы будущая сеть для других
-платформ встроилась без переделки. Крипто-сети (AdsGram/AdMob) отвергнуты — нет легального
-рублёвого дохода самозанятому (НПД).
-
-**Ролик за награду** (добровольное видео за Фишки) начисляет Фишки через платёжный домен по
-**серверному verify-колбэку** сети (клиенту не верим, как платежу). Антифрод на старте — только
-verify провайдера (своего дневного потолка пока нет; абстракция позволит добавить лимиты
-позже).
-
-**Полноэкранный ролик** (после хода), конфигурируемые серверные значения:
-
-- Глобальный кулдаун **на пользователя, сквозь все партии**, дефолт **5 мин**.
-- **`vs_ai` — 30 мин** (соосно кулдауну подсказок, чтобы не отпугивать казуалов).
-- Применение **подсказки** триггерит ролик после хода **независимо** от основного кулдауна,
-  со своим кулдауном **1 мин**.
-- Оффлайн — только баннер.
-- Уважать собственные лимиты частоты VK.
-
-**Оффлайн без рекламы**, кроме нашего баннера. Бенефит `без рекламы` гасит баннер через
-существующий `ads.Eligible` (`backend/internal/ads/ads.go`), который расширяется до гейта по
-**origin-бенефиту, применимому в текущем контексте**, а не по одному глобальному флагу.
-
-## 11. Админ, аудит, отчётность
-
-**Неизменяемый журнал операций + материализованный баланс.** Журнал операций **только на
-INSERT** (никогда UPDATE/DELETE — полный аудит). Балансы сегментов `(account, source)` и
-бенефиты `(account, origin)` — быстрый **материализованный** кэш, обновляется **в той же
-транзакции**, что и запись журнала, и пересчитывается из журнала для сверки.
-
-**Награждение админом.** Админ начисляет **только конкретные ценности** (без рекламы /
-подсказки) — **никогда не Фишки** (подаренный баланс валюты = обход кассы стора). Админ
-**выбирает origin** при выдаче (ответственность за комплаенс на нём: `origin=vk`
-точечно/малый объём = низкий риск, `origin=direct` = безопасно). Грант — транзакция журнала
-типа `admin_grant`, цена 0 Фишек — полный аудит наград.
-
-**Финансовый отчёт по пользователю** в админке `/_gm` — балансы сегментов, платежи, траты,
-гранты, возвраты, полная история — расширение существующей карточки (`UserDetailView`,
-`handlers_admin_console.go`). Плюс экспорт журнала.
-
-## 12. Налоги и комплаенс
-
-Чеки формируются автоматически **на стороне провайдера** и отличаются по каналу:
-
-- **Robokassa** (direct) — чек НПД самозанятого при оплате.
-- **VK** — VK сам процессит Голоса через налоговую; делать нечего.
-- **TG Stars** — налоговой стороны нет (для РФ-самозанятого Stars легально невыводимы = не
-  доход НПД; принимаем, чек не формируем).
-
-**ОРД** (маркировка рекламы) по VK-рекламе — на стороне VK. (Не юридическая консультация —
-владелец сверяет точную схему НПД с налоговым консультантом.)
-
-## 13. Дистрибуция (native Android)
-
-- **RuStore** — Robokassa/внешний гейт разрешён (0%); native = чистый контекст `direct`.
-- **Google Play** — direct-покупки **скрыты**; «Кошелёк» показывает заглушку («установите
-  версию из RuStore для покупок»). Ролик за награду и трата уже накопленных Фишек работают.
-  Перед GP-релизом свериться с актуальными правилами Google по внутренней валюте.
-
-## 14. Модель данных (схема `payments`)
-
-Платёжный домен живёт в **своей схеме `payments`** в общем инстансе Postgres, со своим
-DB-ролём (права только на `payments`) и доменным пакетом за жёстким интерфейсом.
-**Cross-schema внешнего ключа** к `backend.accounts` **нет** — идентификатор аккаунта здесь
-обычное значение, согласуемое в коде и связываемое с tombstone-аккаунтом / досье
-retained-identities по стабильному id. Это держит трату «Фишки↔бенефит» атомарной **внутри
-`payments`** и делает домен извлекаемым в свою базу. Сохранность — **PITR** (непрерывный
-WAL-архив), независимо от топологии базы.
-
-Основные таблицы (финальные имена/колонки — в `PLAN.md`):
-
-- **журнал операций (ledger)** — append-only операции: пополнение / трата / `admin_grant` /
-  возврат; `(провайдер, provider_payment_id)` уникален для защиты от повторов;
-  экспортопригоден.
-- **балансы** — материализованные `(account_id, source) → Фишки`.
-- **бенефиты** — материализованные `(account_id, origin)` → «без рекламы»
-  `paid_until`/`forever` + счётчик подсказок.
-- **каталог** — атомы + продукты (деактивируемые), цены per-метод, курсы покупки Фишек,
-  награда за ролик.
-- **заказы (orders)** — pending-покупки, `order_id`, ожидаемая сумма, origin, статус
-  (pending/paid/expired).
-- **payment_events** — succeeded/failed/refunded для диспетчера.
-
-Legacy `accounts.hint_balance` и `accounts.paid_account` **устаревают** в пользу
-сегментированной модели и удаляются в отдельной **contract-миграции** (expand-contract, после
-того как валютное ядро переключит чтения, и после Release 2 — откат образа остаётся безопасным
-для БД); ни то, ни другое в проде никогда не выставлялось (потока покупки не было), поэтому
-legacy-значения обнуляются.
-
-## 15. Словарь
-
-- **Фишка** — игровая валюта; единая единица, сегментирована по `source`.
-- **source (источник)** — где пополнены Фишки (`vk`/`telegram`/`direct`).
-- **origin (происхождение)** — где куплена ценность; определяет, где действует бенефит.
-- **ценность / бенефит** — то, что покупается за Фишки (без рекламы, подсказки, турнирный
-  взнос).
-- **гейт** — одностороннее правило комплаенса сторов (§4).
-- **журнал операций (ledger)** — неизменяемая запись всех операций с деньгами/ценностями.
-- **платёжный канал / рельса** — платёжный провайдер (Robokassa / Голоса VK / Stars TG).

 **SPA** at `/app/` (web), `/telegram/` (the Telegram Mini App) and `/vk/` (the VK Mini App) — the single-origin model.
-The web SPA is an installable **PWA**: it serves `manifest.webmanifest` (unhashed from `ui/public/`,
-with the `.webmanifest` MIME type registered in-process — the distroless image has no
-`/etc/mime.types`) and the app-shell `sw.js` (built from `ui/src/sw.ts` by vite-plugin-pwa, which
-precaches the shell + assets so an installed PWA cold-launches offline).
 Hash-named `/assets/*` are served `immutable`; the HTML shells are `no-cache`. It can also serve the
 backend's admin console at `/_gm` behind HTTP Basic-Auth for a local non-caddy run;
 in the deployed contour the front caddy owns `/_gm` (see
