 # SWEAT the TOKEN
 
-#### 📦 Dependencies
+The SWEAT fungible token (NEP-141 / NEP-148) for the Sweat Economy move-to-earn
+protocol. Tokens are minted by trusted Oracles in proportion to user steps, using
+a decaying issuance formula tied to the global step count since the Token
+Generation Event (TGE).
+
+## What the contract does
+
+- **Deferred minting.** Oracles submit batches of `(account, steps)` via
+  `defer_batch`. For each batch the contract computes the SWEAT payout using
+  the issuance formula in `math.rs`, splits it **95% user / 5% Oracle fee**,
+  and performs an XCC to the configured **holding contract**
+  (`holding_account_id`). On a successful callback (`on_record`), the user
+  portion is minted to the holding contract and the fee to the calling Oracle.
+  On failure, the `steps_since_tge` counter is rolled back. End users later
+  claim from the holding contract — see
+  [sweat-claim](https://github.com/sweatco/sweat-claim).
+- **Denylist.** A `DenylistManager` role can mark accounts as restricted via
+  `set_restricted`. Restricted accounts cannot send, receive, or burn tokens.
+- **Pausability.** `PauseManager` / `UnpauseManager` roles can pause/unpause
+  groups of methods. Two pause groups are defined: `minting` (covers
+  `defer_batch`) and `token` (covers transfers and `burn`).
+- **Access control.** All privileged roles (`Oracle`, `DenylistManager`,
+  `PauseManager`, `UnpauseManager`, plus the Super Admin) are managed by the
+  [`near-plugins`](https://github.com/aurora-is-near/near-plugins)
+  `AccessControllable` plugin. Use `acl_grant_role` / `acl_revoke_role`.
+- **NEP-141 / NEP-145 / NEP-148.** Standard FT core, storage management, and
+  metadata are implemented. Transfers add denylist + pause checks on top of
+  the standard.
+
+See `recon-report.md` for a deeper architectural walkthrough.
+

-./sweat/build.sh
-//The wasm file will be at `res/sweat.wasm`
+- Rust toolchain (see `rust-toolchain.toml`) — `rustup target add wasm32-unknown-unknown`
+- [`cargo-near`](https://github.com/near/cargo-near) for building the contract
+- [`near-cli-rs`](https://github.com/near/near-cli-rs) for deployment / interaction
+  (the legacy JS `near-cli` is **not** what the commands below use — install via
+  `cargo install near-cli-rs` or the install script in that repo)
+- Docker (only if you want reproducible builds via `make dock`)

+## Vendored `near-contract-standards`
 
-## Usage
+`vendors/near-contract-standards/` is a vendored copy of upstream
+[`near-contract-standards`](https://crates.io/crates/near-contract-standards)
+with local modifications (notably `LookupMapAdapter` for the SWEAT account-id
+storage layout). **The vendored directory is the source of truth** — edit it
+directly and commit. There is no separate patch file to keep in sync.
+
+To refresh the vendor from upstream — for example after bumping `near-sdk` in
+the workspace `Cargo.toml`:
 
 ```bash
-export TOKEN_ACCOUNT_ID=your-token-account-id
+make sync
 ```
 
-Deploy and initialize the contract:
+The script reads the currently vendored version, diffs it against pristine
+upstream to capture local changes, replaces the vendor with the target
+upstream version (from `[workspace.dependencies] near-sdk`), and re-applies
+the captured diff. If a hunk fails, `*.rej` files are written and the script
+aborts — resolve manually and commit; the next `make sync` will derive a
+fresh diff from the resolved state.
+
+## Build, lint, test
+
+All common tasks are wired through the `Makefile`:
 
 ```bash
-near deploy --accountId=$TOKEN_ACCOUNT_ID --wasmFile=res/sweat.wasm --initArgs '{"postfix": ".u.sweat.testnet"}' --initFunction new
+make help              # list all targets
+make install           # npm i near-cli && cargo build
+make build             # local contract build (./scripts/build.sh)
+make build-integration # contract build with `integration-test` feature
+make build-stub        # build the holding-contract stub
+make dock              # reproducible build in Docker
+make test              # cargo test --package contract
+make int               # integration tests (builds with integration-test feature first)
+make int-log           # same, with logs streamed serially (override RUST_LOG)
+make cov               # cargo llvm-cov coverage report
+make fmt               # cargo +nightly fmt --all
+make lint              # clippy
 ```
 
-Add an oracle
+## Deploy & initialize
+
+All examples below use `near-cli-rs`. Swap `network-config testnet` for
+`network-config mainnet` as appropriate.
 
 ```bash
-export ORACLE_ACCOUNT_ID=your-oracle-account-id
+export TOKEN_ACCOUNT_ID=your-token-account-id
+export HOLDING_ACCOUNT_ID=your-holding-account-id
+
+near contract deploy $TOKEN_ACCOUNT_ID \

+    prepaid-gas '100.0 Tgas' \
+    attached-deposit '0 NEAR' \
+  network-config testnet \
+  sign-with-keychain \
+  send
 ```
 
+The deploying account becomes the **Super Admin** and can grant any role.
+
+## Granting roles
+
+Roles are managed through `near-plugins` ACL. Replace `Oracle` with
+`DenylistManager`, `PauseManager`, or `UnpauseManager` as needed.

+//! Deferred minting via the holding account.
+//!
+//! Newly minted user rewards are **not** credited to end-user accounts at mint
+//! time. End users must **actively claim** their rewards from a separate
+//! protocol-owned contract — the *holding account* — which is the only party
+//! (besides the Oracle fee) that this contract ever mints user-portion tokens
+//! to.
+//!
+//! # Roles
+//!
+//! - **This contract** owns the supply and controls minting. It never keeps a
+//!   per-user ledger of unclaimed rewards.
+//! - **Holding account** ([`Contract::holding_account_id`]) is a separate,
+//!   protocol-owned smart contract. It is trusted by this contract (which is
+//!   why [`crate::core::InternalDeposit::internal_deposit`] is allowed to skip
+//!   storage registration for it — see the doc-comment there). The holding
+//!   contract maintains the per-user ledger of unclaimed rewards and releases
+//!   tokens on claim.
+//! - **End user** earns steps. After a batch is recorded, the user calls the
+//!   holding contract to claim their accumulated balance; the holding contract
+//!   then performs a standard NEP-141 `ft_transfer` from itself to the user.
+//!
+//! # Batch lifecycle: from steps to a claimable balance
+//!
+//! 1. An [`Role::Oracle`] grantee calls [`SweatDefer::defer_batch`] with a
+//!    `Vec<(AccountId, steps)>`.
+//! 2. This contract computes `(amount, fee)` per `(user, steps)` pair, sums
+//!    them, advances `steps_since_tge`, and packs the per-user breakdown into
+//!    `amounts: Vec<(AccountId, U128)>`.
+//! 3. It calls `record_batch_for_hold({ amounts })` on the holding account.
+//!    This is the hand-off point: the holding account persists the per-user
+//!    accounting (so it knows exactly how much each user is owed) *before* any
+//!    tokens exist.
+//! 4. The [`FungibleTokenTransferCallback::on_record`] callback:
+//!    - **on success** mints `total_effective` (the user portion) to
+//!      [`Contract::holding_account_id`] and `total_fee` to the Oracle that
+//!      submitted the batch, and emits two [`FtMint`] events. The user portion
+//!      now sits in the holding account's NEP-141 balance on this contract,
+//!      earmarked in the holding contract's own storage for the individual
+//!      users recorded in step 3.
+//!    - **on failure** rolls back `steps_since_tge` and mints nothing. The
+//!      holding account is expected to treat its own `record_batch_for_hold`
+//!      call as transactional and not credit users for a batch whose mint did
+//!      not land.
+//! 5. Later, an end user calls a claim method on the **holding contract** (out
+//!    of scope of this crate — it is a separately deployed contract). The
+//!    holding contract decrements that user's internal ledger and issues a
+//!    standard `ft_transfer` from `holding_account_id` to the user.
+//!
+//! # Invariants
+//!
+//! - `ft_balance_of(holding_account_id)` represents the pool of unclaimed user
+//!   rewards plus any residual rounding dust. The holding account custodies
+//!   this balance for users; it does not own it economically.
+//! - There is no path on this contract by which a user receives newly minted
+//!   rewards directly. Every reward path for end users goes through the
+//!   holding contract's claim flow, which uses ordinary NEP-141 transfers and
+//!   is therefore subject to the standard denylist and pause checks in
+//!   [`crate::core`].
+//! - This contract has no visibility into per-user pending balances. "What
+//!   does Alice still have unclaimed?" must be answered by reading the holding
+//!   contract's state, not this one.
+//! - The trust assumption is explicit: a compromised or buggy holding contract
+//!   could mis-credit users or fail to release claims, but it cannot mint
+//!   additional supply — minting authority remains with the Oracle role and is
+//!   gated by [`SweatDefer::defer_batch`].

+# Re-vendor near-contract-standards from upstream, preserving local modifications.

+# Source of truth is the vendor directory itself (`vendors/near-contract-standards/`).
+# Local modifications are derived on the fly by diffing the live vendor against the
+# pristine upstream tarball at the version it was based on. After the target upstream
+# version is dropped in, that diff is re-applied.
+#
+# Workflow:
+#   1. Read CURRENT version from vendor's Cargo.toml.
+#   2. Download pristine CURRENT from crates.io and diff against live vendor — this
+#      captures every local modification, regardless of who made it or when.
+#   3. Read TARGET version from workspace [workspace.dependencies] near-sdk.
+#   4. Download TARGET from crates.io and replace the vendor directory.
+#   5. Re-apply the captured diff.
+#
+# If a hunk fails (upstream changed near our modification site), `patch` writes .rej
+# files and aborts. Inspect, resolve manually, and commit the resolved state.
+# The next `make sync` will re-derive a fresh diff from your resolved vendor.
