Rather than only asserting "authorized +succeeds / unauthorized fails", each test inspects `env.auths()` after the call and pins +**which address the host actually required an authorization from**. + +This catches two regressions a pass/fail test misses: a `require_auth` silently dropped +(auth set becomes empty), and an auth subject rebound to the wrong argument. + +Writing the suite surfaced three real authorization defects and a set of pre-existing build +breakages that stopped the crate compiling at all. Both are fixed here so the suite can run. + +## Changes + +**Tests** + +- `tests/auth_snapshot.rs` (new) — 24 tests: committed-snapshot assertions for 13 + entrypoints, auth-boundary assertions for 3, read-only entrypoints pinned to *no auth*, + plus edge cases (wrong-subject binding, subject tracking across users, non-admin + rejection, `#[should_panic]` no-auth traps). The fixture registers a real Stellar Asset + Contract so stake transfers commit. +- `Cargo.toml` — registered the `auth_snapshot` test target. + +**Authorization fixes** + +Soroban rejects a second `require_auth` on an already-authorized frame +(`Error(Auth, ExistingValue)`). Three paths authorized the same address twice — entrypoint +*and* inner manager — so they could **never succeed on-chain**: + +- `fees.rs` — redundant `admin.require_auth()` in `FeeManager::collect_fees`. It was + `#[cfg(not(test))]`-gated, so unit tests masked it while production builds hit it. +- `disputes.rs` — redundant `user.require_auth()` in `DisputeManager::dispute_market`. +- `rate_limiter.rs` — redundant `user.require_auth()` in `rate_limit_voting` / + `rate_limit_disputes`. + +Auth strength is unchanged: each is still enforced by the calling entrypoint +(`require_primary_admin` for admin paths, `user.require_auth()` for user paths). + +**Build restoration** + +The crate did not compile on `master`: `e5db2d8` collapsed `lib.rs` to a "minimal working +version" and later PRs re-added call sites without restoring their definitions. + +- `lib.rs` — restored 14 dropped `mod` declarations; the `initialize` / `deposit` / + `withdraw` / `get_balance` entrypoints; the admin-auth helpers (`stored_primary_admin`, + `require_primary_admin{,_or_panic}`, `require_initialized_admin_root`, + `require_admin_permission`); the `SYM_*` / `PERCENTAGE_DENOMINATOR` constants and the + `resolution_timeout_reached` / `automatic_oracle_result_unavailable` helpers. Removed + duplicate imports, fixed 7 invalid `Address` derefs, repointed `capabilities()`. +- `resolution.rs` — repaired a mis-merge that spliced a payout-distribution body into + `impl ResolutionOutcomeCache` and into `determine_outcome_from_oracle_data`; restored the + cache methods 6 modules call, `ResolutionAnalytics` / `MedianResolutionResult`, and the + `OracleResolutionManager` impl boundary. +- `market_id_generator.rs` — restored the clean file from `28c8db4`. +- `err.rs` — removed a duplicate `ReplayedOverride`; added 6 declared-nowhere variants; + catch-all arms on `description()` / `code()`. +- `storage.rs` — removed a duplicate `AdminOverrideNonce`; added `PlaceBetsIdem` and + `AntiGriefFloor`. +- `gas.rs` — `Env::budget()` is test-only, so `BudgetGuard` degrades to a no-op outside + tests; fixed an oversized `symbol_short!` and an invalid `Default` derive. +- `upgrade_manager.rs` — fixed a `u32`/`u64` branch mismatch. + +## Auth matrix + +| Entrypoint | Subject | Verified by | +|---|---|---| +| `create_market`, `resolve_market_manual`, `collect_fees`, `set_platform_fee`, `set_treasury`, `set_global_claim_period`, `set_market_claim_period`, `extend_deadline` | admin | committed snapshot | +| `sweep_unclaimed_winnings` | admin | auth boundary | +| `vote`, `place_bet`, `cancel_bet` | user | committed snapshot | +| `claim_winnings`, `dispute_market` | user | auth boundary | +| `get_market`, `get_market_bet_stats` | none | committed snapshot | + +*Committed snapshot* — the call is driven through a fully satisfied happy path and the auth +is read back from `env.auths()`. *Auth boundary* — the host rolls back recorded auths when a +call traps or returns `Err`, so entrypoints needing state the fixture does not build assert +instead that an authorized call gets *past* `require_auth` while an unauthorized one traps. + +## API / visible changes + +None.
