WalkthroughThe PR adds a feature-gated deterministic fault oracle for storage publication and restart behavior. It models durable filesystem state, crash phases, torn metadata, authority resolution, minimized histories, native agreement, and contract coverage evidence. ChangesStorage fault oracle
Estimated code review effort: 4 (Complex) | ~45 minutes Merge Risk: 🟡 Moderate · up to This PR adds a durability fault oracle and contract coverage, but current behavior can misclassify recovery failures, model power-loss outcomes incorrectly, and report native agreement without comparing native results; the contract gate also does not run the cited Rust tests. These gaps could create false confidence in crash-recovery guarantees, so merge should wait for correction. Sequence Diagram(s)sequenceDiagram

Preserve distinct recovery error classes in the contract evidence. classify_resolution currently maps every Err(_) to AuthorityClass::Corrupt, so torn_current_and_manifest_fail_closed also passes for unrelated failures. This makes the matrix's required_authority stronger than the test proves. Match ProjectErrorCode::ProjectCorrupt explicitly and treat other errors as unexpected, or return the error for callers to assert directly; the phase sweep should reject unexpected outcomes.

native_agreement_table compares a value to itself.
native is computed as if phase.is_linearized() { NewGeneration } else { PriorGeneration }. expected_authority (Lines 742-748) has the same body. Both tuple elements are therefore always equal, and the assertion in native_and_simulated_results_agree_at_shared_phase_boundaries (Lines 1216-1221) cannot fail.
The doc comment states that this compares simulated outcomes to native subprocess-kill authority classes, and the linked issue requires agreement with native results at shared phase boundaries. Nothing in this function reads a native result. Derive the native column from the native matrix expectations, for example from the per-failpoint required_authority values in tests/contracts/durability-isolation-matrix.json, or from a shared table that project_recovery.rs also consumes.
The second loop of that test (Lines 1223-1230) is meaningful, because it exercises resolve_project_generation through simulate_all_phases. Keep it.

Assert against the actual temporary root, not fixed substrings.
!encoded.contains("/Users/") and !encoded.contains("password") are proxies. Neither catches a Linux or Windows absolute path, and neither proves that the report omits host paths. Simulation runs inside a tempfile::tempdir(), so assert that no component of that path appears in the encoded report. That requires simulate_crash to expose the root, or a variant that accepts a caller-supplied root. A simpler check that holds today: assert the encoded report contains no /tmp/ or platform separator prefix and that every trace path starts with a known project-relative prefix.
