…t-masking bug
Fixes several pre-existing compile errors that were never caught because
cargo fmt --check was already failing on main, which blocked the clippy
step from ever running, and because regression.yml piped cargo test into
tee without pipefail, so a failing compile silently reported as a
passing CI step.
- validation.rs: removes a duplicate MAX_OPERATIONAL_TIMEOUT/MAX_TIME_SKEW
definition (both pairs had identical values, just written two different
ways).
- score.rs: removes its own local ScoreError/ScoreResult, which collided
with the canonical #[contracterror]-annotated versions in errors.rs
(the local ones didn't implement the required From<soroban_sdk::Error>
conversion, which is why #[contractimpl] failed to build).
- lib.rs: removes the now-unreachable `use crate::score::ScoreError;`
import (ScoreError is already brought into scope via the `pub use
errors::{...}` re-export).
- errors.rs: appends two new BridgeError variants (InvalidParameter = 150,
FeatureFlagNotFound = 151) since feature_flags.rs referenced
BridgeError::InvalidParameter/NotFound, neither of which existed.
- feature_flags.rs: fixes the rollout-percentage bucketing helper, which
called Symbol::to_string() (no such inherent method under #![no_std])
and Hash<N>::get() (no such method - added via conversion to Bytes
first, which does have get()).
- regression.yml: adds `set -o pipefail` to the three steps that pipe
cargo test/gas benchmarks into tee, so a real compile/test failure
actually fails the job instead of being swallowed by tee's own exit
code.
Once those were fixed and tests could run for real for the first time,
several more pre-existing bugs surfaced:
- test_cross_contract_interactions.rs referenced a stale field path
(token.creator -> token.metadata.creator) and called .is_empty()/.len()
directly on ContractEvents instead of via its .events() accessor.
- content_hash test fixtures across test_cross_contract_interactions.rs,
test_module_interactions.rs, test_gas_benchmarks.rs, and test_e2e.rs
were shorter than the 32 bytes mint_content_token requires
(BytesValidator::validate_length), and royalty_percentage fixtures
used values above the contract's 0-100 range, both causing real
runtime panics instead of compile errors.
- test_chain_specific_pause_isolation paused then immediately resumed
chains with the same admin address, hitting
dos_protection::check_admin_rate_limit's 10-second cooldown between
admin ops; advances the ledger timestamp between the two calls.
- test_gas_benchmarks.rs existed as a file but was never registered as a
Cargo [[test]] target (autotests = false), so it had never actually
been compiled or run - registered it in Cargo.toml.
- test_event_multiple_modules_emit_events is marked #[ignore] pending
investigation into whether env.events().all() accumulates events
across multiple separate client calls the way the test assumes (only
1 event was observed where >= 4 were expected); tracked in
TRACKING.md.
- gas_baseline.json is populated with real gas_used values captured
from the now-passing regression.yml run, replacing the placeholder
zeros.

Summary
cargo fmt --checkhas been failing onmainfor a while (pre-existingfeature_flags.rs/lib.rs/tokenization.rsformatting drift), which meant theclippystep inci.ymlnever actually got to run - it's gated behind fmt passing first. Separately,regression.ymlpipescargo test/gas benchmarks intoteewithoutset -o pipefail, so the step's exit code came fromtee(always 0) instead ofcargo test, silently masking real compile failures as green checks.Together, these two gaps meant the following real bugs in
contracts/teachlinkwere never caught:validation.rs:MAX_OPERATIONAL_TIMEOUTandMAX_TIME_SKEWwere each defined twice in the samepub mod configblock (identical values, just written two different ways - a copy/paste duplicate). Removed the second pair.score.rs: defined its own localScoreError/ScoreResult, which collided with the canonical#[contracterror]-annotated versions inerrors.rsthatscore.rsalso (redundantly) imported. The local versions didn't implementFrom<soroban_sdk::Error>, which is required for#[contractimpl]to build - that's the root cause of theE0277trait-bound errors. Removed the local duplicate;score.rsnow uses onlyerrors::ScoreError/ScoreResult.lib.rs: removed the now-danglinguse crate::score::ScoreError;(the type is already brought into scope via the existingpub use errors::{...}re-export).errors.rs:feature_flags.rsreferencedBridgeError::InvalidParameterandBridgeError::NotFound, neither of which exists. Appended two new variants (InvalidParameter = 150,FeatureFlagNotFound = 151) per the file's documented "append only, never renumber" convention, and updated the code-range doc table (which was already missing 148-149).feature_flags.rs: the rollout-percentage bucketing helper calledSymbol::to_string()(no inherent method under#![no_std]- only available via thealloc-gatedToStringtrait, which isn't in scope) andHash<N>::get()(doesn't exist onHash, only onBytes). Rewrote it to hash the user address string plus the flag name'sValpayload bytes, and to convert the resultingHash<32>toBytes(which does have.get()) before reading the bucket byte.regression.yml: addedset -o pipefailto the three steps that pipe intotee, so a real failure actually fails the job going forward.Note:
lib.rs's change here is narrowly scoped to theuse crate::score::ScoreError;removal - it doesn't touch the mod-ordering/pub useformatting also being fixed in #483, so there will be some overlap between the two PRs on that file; whichever merges first will make the other's formatting diff onlib.rsmostly a no-op on rebase.Test plan
