-""":descr: 5/6 validator_quorum, 4/6 participant_aligned (tier 2), recovery
-
-Requires node_count: 6 (see suite.yml) — the smallest NON-degenerate Tier 2
-size. At n=6: tier2 floor = 4, validator quorum = 5, validation quorum = 5. So
-  6/6, 5/6 present -> validator_quorum  (EntropyTier=3)
-  4/6 present      -> participant_aligned (EntropyTier=2, count 4)   <-- the band
-  3/6 present      -> consensus_fallback (EntropyTier=1)
-n=5 has NO tier-2 band (tier2 == quorum == 4), which is why the existing
-degradation smoke at 5 nodes only ever sees tier 3 / fallback.
-
-KEY: the 4/6 window is BELOW the 80% validation quorum (5). The 4 survivors
-keep CLOSING ledgers that carry tier-2 entropy, but those ledgers do NOT
-validate until the network recovers — exactly the transition window Tier 2
-serves. So validated_ledger_index() stalls; we instead inspect a surviving
-node's CLOSED ledger (its LCL) directly, and cross-check the injection from the
-cohort's logs.

 ## XAH
+
 XAH is the public, counterparty-free asset native to Xahau and functions primarily as network gas. Transactions submitted to the Xahau network must supply an appropriate amount of XAH, to be burnt by the network as a fee, in order to be successfully included in a validated ledger. In addition, XAH also acts as a bridge currency within the Xahau DEX. XAH is traded on the open-market and is available for anyone to access. Xahau was created in 2023 with a supply of 600 million units of XAH.

 The server software that powers Xahau is called `xahaud` and is available in this repository under the permissive [ISC open-source license](LICENSE.md). The `xahaud` server software is written primarily in C++ and runs on a variety of platforms. The `xahaud` server software can run in several modes depending on its configuration.

 # Antithesis C++ SDK
 
 This library provides methods for C++ programs to configure the [Antithesis](https://antithesis.com) platform. It contains three kinds of functionality:
-* Assertion macros that allow you to define test properties about your software or workload.
-* Randomness functions for requesting both structured and unstructured randomness from the Antithesis platform.
-* Lifecycle functions that inform the Antithesis environment that particular test phases or milestones have been reached.
+
+- Assertion macros that allow you to define test properties about your software or workload.
+- Randomness functions for requesting both structured and unstructured randomness from the Antithesis platform.
+- Lifecycle functions that inform the Antithesis environment that particular test phases or milestones have been reached.

-# xahau_consensus
-
-Lean proofs for small Xahau consensus invariants.
-
-This package is intentionally narrow. It does **not** try to verify the C++
-implementation directly. It mirrors small formulas and decision ladders from
-the consensus-extension code so the safety arguments can be checked as theorems
-instead of repeatedly re-derived in review notes.
-
-Current modules:
-
-- `XahauConsensus.Threshold`
-  - mirrors `calculateParticipantThreshold`
-  - proves the Tier-2 intersection inequality:
-    `count + floor(count / 5) < 2 * participantThreshold count`
-  - proves the threshold is minimal for that strict inequality
-  - proves the original-view threshold remains safe when nUNL shrinks the
-    effective view
-  - includes the `original=10`, `effective=8` regression example showing why
-    using the effective view for the Tier-2 floor is forkable
-  - proves `participantThreshold count <= quorumThreshold count` for
-    non-empty views
-  - distinguishes raw formula helpers from the live safety-wrapped gate
-    thresholds used by `ConsensusExtensions`
-- `XahauConsensus.ThresholdFacts`
-  - records small-network values and band-empty/band-present examples
-  - proves exact multiple-of-five behavior
-  - proves threshold monotonicity facts
-- `XahauConsensus.SixtyPercent`
-  - defines a naive `ceil(60%)` threshold
-  - proves naive 60% is unsafe at exact multiples of five
-  - proves the live derived floor is one higher there and restores strict
-    intersection safety
-- `XahauConsensus.Intersection`
-  - proves the abstract cardinality argument behind quorum intersection
-  - shows two threshold-sized cohorts must overlap above the fault bound
-    whenever `n + f < 2t`
-  - specializes that argument to the live participant threshold, including
-    nUNL-shrunk effective views
-- `XahauConsensus.HonestOverlap`
-  - bridges overlap arithmetic to the consensus claim that two cohorts share at
-    least one honest validator
-  - specializes that bridge to the participant threshold and `floor(n/5)` fault
-    bound
-- `XahauConsensus.ViewUniverse`
-  - proves original-view anchoring remains safe under nUNL shrink
-  - separates strict safety from threshold reachability
-  - defines cross-view participant-band presence/absence
-  - shows effective-view thresholds can be unsafe against the original fault
-    bound
-  - shows trusted-superset counting universes erode the intersection margin
-- `XahauConsensus.NunlCap`
-  - models the protocol's ceil-25% nUNL disablement cap
-  - proves 8/6 and 10/8 band collapse examples
-  - records that 10 at max cap has effective view 7, below the original
-    participant floor
-  - records the important counterexample: original `20`, effective `15` does
-    **not** make validator quorum meet the original participant floor
-- `XahauConsensus.SidecarAlignment`
-  - models aligned participant counting for sidecar hashes
-  - proves non-active peers and non-active local publication cannot pad the
-    alignment count
-  - proves changing nonmember reports cannot change quorum alignment
-- `XahauConsensus.EntropySelector`
-  - models the tier-label ladder from `ConsensusExtensions::selectEntropy`
-  - proves non-UNLReport views select fallback
-  - proves the quorum / participant / fallback bands select the expected tier
-- `XahauConsensus.SelectorDeterminism`
-  - models labeled digest output
-  - proves digest payload bytes do not affect the label when consensus metadata
-    is fixed
-  - records examples where changing view provenance or view sizes changes labels
-- `XahauConsensus.ExportGate`
-  - models export's quorum-aligned success rule
-  - models export's sidecar-gate outcome as `proceed` or `retryOrExpire`, with
-    no deterministic fallback signature set
-  - proves missing minority observation does not block a quorum-aligned export
-  - proves `fullObservation` alone cannot change the export decision
-- `XahauConsensus.ExportQuorum`
-  - proves two 80% export quorums overlap above the standard Byzantine bound
-    in nonempty active universes
-  - proves export quorum overlap remains above the original-view Byzantine
-    bound when nUNL shrinkage is within the protocol cap
-  - proves Byzantine validators at the standard bound cannot veto quorum
-  - records concrete overlap margins for 5/10/20-validator universes
-- `XahauConsensus.FinsetIntersection`
-  - uses Mathlib finite sets to prove the cardinality premise behind the
-    arithmetic intersection theorems
-  - specializes that bridge for Tier-2 cohorts, nUNL-shrunk cohorts, and export
-    80% quorums
-- `XahauConsensus.Invariants`
-  - restates cross-module design contracts in one place
-  - pins the live safety-wrapped threshold relationship
-  - proves the cross-view entropy gate is exactly the selector's non-fallback
-    boundary
-  - pins non-UNLReport fallback and export full-observation independence
-
-Run:
-
-```sh
-~/.elan/bin/lake build
-```
-
-## Optional C++ cross-checks
-
-The xahaud CMake build can also compile a Lean-backed unit-test path, but it is
-off by default and is not part of normal release builds:
-
-Install Lean through `elan` first. The CMake integration intentionally keeps the
-tooling rule simple: when `formal_verification=ON`, it looks for `lake` on
-`PATH` or in `~/.elan/bin`, asks that Lake environment to run `lean --version`,
-verifies the exact version specified by this package's `lean-toolchain`, then
-asks Lake for `LEAN_SYSROOT` and checks that `lean.h` and `libleanshared`
-exist.
-
-```sh
-conan install . --output-folder=build-formal --build=missing \
-  -s build_type=Release \
-  -o '&:tests=True' \
-  -o '&:xrpld=True' \
-  -o '&:formal_verification=True'
-
-cmake -S . -B build-formal-cmake \
-  -DCMAKE_TOOLCHAIN_FILE=$PWD/build-formal/build/generators/conan_toolchain.cmake \
-  -Dtests=ON \
-  -Dxrpld=ON \
-  -Dformal_verification=ON
-
-cmake --build build-formal-cmake --target rippled
-./build-formal-cmake/rippled --unittest=LeanConsensus
-```
-
-This path currently supports native test builds only. It builds
-`XahauConsensus:static`, links the resulting Lean archive and runtime into the
-test binary, and runs C++ drift tests over selected scalar formulas and helper
-predicates. Some checks compare directly to named production helpers; others are
-review-oriented safety predicates computed from those helpers. The exported
-surface is intentionally scalar and reviewable:
-
-- Byzantine bound, participant threshold, and validator quorum threshold.
-- The safety-wrapped zero-view thresholds used by the live gates.
-- The cross-view entropy gate threshold, with effective and original view
-  denominators kept separate.
-- The entropy tier selector policy for `(fromUNLReport, participantCount,
-  effectiveView, originalView)`.
-- Sidecar aligned-participant counting, full-observation, quorum-aligned
-  predicates, and active-view mask-counting samples.
-- Export's quorum-only sidecar-gate proceed predicate, where `fullObservation`
-  is diagnostic rather than success-gating; a small final-apply snapshot model
-  makes explicit that gate proceed is not the same as closed-ledger
-  `Export::doApply` success.
-- NegativeUNL cap/effective-view arithmetic.
-- View-universe safety predicates and naive-60% regression anchors.
-
-This is still a model-to-code cross-check, not a proof that the C++ implements
-the Lean model. Its value is narrower and practical: if a production formula,
-decision ladder, or helper predicate changes without the formal model changing
-too, the gated unit test fails. The formal CMake target invokes Lake on each
-formal-enabled `rippled` build and lets Lake decide whether its own artifacts
-are current; CMake does not trust an existing source-tree archive by timestamp.
-Lake still writes build artifacts under the Lean workspace's `.lake/`
-directory, and the Conan recipe intentionally excludes that directory from
-exported sources, so keep this option as a local/CI confidence build rather
-than a release packaging input. The Conan recipe rejects
-`formal_verification=True` unless `tests=True` and `xrpld=True`, and refuses to
-package formal-enabled builds.

-# Xahau Lean Roadmap
-
-This package should stay focused on invariants that are compact enough to be
-reviewable and stable enough to mirror from C++.
-
-Good targets:
-
-1. Threshold arithmetic
-   - Tier-2 participant threshold formula
-   - quorum threshold relation
-   - nUNL original-view anchoring
-   - small-network boundary examples
-2. Sidecar alignment
-   - active-view-only counting
-   - quorum-aligned predicate
-   - full-observation as diagnostic vs success precondition where applicable
-3. Entropy selector
-   - non-UNLReport fallback
-   - tier ladder from agreed participant count
-   - no local pending-state dependency in the tier decision
-4. Export gate
-   - quorum-aligned success without full observation
-   - no deterministic fallback value
-   - retry/expire as liveness behavior, not ledger-content substitution
-
-Poor targets for this package:
-
-- direct verification of C++ implementation details
-- wall-clock timing and network scheduling liveness
-- full ledger execution semantics
-
-Those belong in C++ tests, CSF/testnet scenarios, or a dedicated temporal model.

-Nat-cardinality arithmetic for export sidecar quorum uniqueness.
-
-The model deliberately stays at the level used by `Intersection.lean`:
-
-* `n` is the active validator universe size.
-* `a` and `b` are the numbers of validators supporting two export sidecar
-  hashes in that same universe.
-* `overlap` is the size of the intersection between those two support sets.
-* `faultyOverlap + honestOverlap = overlap` splits that intersection.
-
-No `Finset` structure is needed here; callers supply the usual
-inclusion-exclusion cardinality inequality `a + b <= n + overlap`.
