Subject: [PATCH] feat: credit staleness, bounded recompute, price oracle,
 budget regression baselines
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Closes #1186 — credit score staleness reporting: track computed_at_ledger
in persistent storage, fill is_stale/ledger_age in get_credit_breakdown.

Closes #1185 — bounded paginated credit recompute: dense CreatorIndex for
O(page) iteration, recompute_credit_scores_page with 50-entry page cap.

Closes #1184 — price oracle interface: OraclePrice type, set/remove/fetch
helpers using try_invoke_contract for graceful degradation, cache fallback.

Closes #1194 — gas/budget regression tests: committed baselines in
budget_baselines.toml, 10% tolerance assertions, CI step for delta report.

+//! Price oracle interface for cross-token XLM normalisation (issue #1184).
+//!
+//! ## Design
+//!
+//! Ranking and leaderboard logic requires a common unit. Without prices, a
+//! 1 000-unit tip in a worthless token outranks 10 XLM. This module defines an
+//! oracle interface so an admin can register an on-chain price source per token.
+//!
+//! ## Staleness & safety
+//!
+//! Prices carry a `updated_at` timestamp. Any price older than
+//! [`ORACLE_PRICE_MAX_AGE_SECS`] is rejected. When no oracle is configured, or
+//! when the oracle reverts, or when the price is stale, the function returns
+//! `None` and callers fall back to counting only the native asset toward
+//! rankings. **Oracle failure must never block tipping**, only ranking.
+//!
+//! ## Admin flow
+//!
+//! ```text
+//! admin → set_token_oracle(token, oracle_contract)
+//!      → on tip: fetch_oracle_price(token) → cache → convert → leaderboard
+//! ```

+//! Budget regression tests against committed baselines (issue #1194).
+//!
+//! Each test re-runs an operation from `test_budget.rs`, compares the measured
+//! CPU and memory cost against the baselines in `budget_baselines.toml`, and
+//! **fails if either metric exceeds `baseline × (1 + tolerance)`**.
+//!
+//! ## Updating baselines
+//!
+//! When a deliberate change raises the cost of an entry point:
+//!
+//! 1. Set `TIPZ_UPDATE_BASELINES=1` in your shell.
+//! 2. Run `cargo test --features testutils 2>&1 | grep -E "BASELINE|budget"`.
+//! 3. Copy the printed values into `budget_baselines.toml`.
+//! 4. Commit both the code change and the updated `budget_baselines.toml` in one
+//!    PR, with a comment explaining the cost increase.
+//!
+//! ## Tolerance
+//!
+//! The default tolerance is 10% above baseline (see `budget_baselines.toml`).
+//! That is wide enough to absorb ledger-to-ledger noise in the test VM but
+//! tight enough to catch a 2× regression immediately.
