Subject: [PATCH 01/49] Add Stage 2 plan section after #1826 foundation merge

The _revived foundation merged in #1826 unblocks the remaining S5-S8 work.
This stacked PR carries Layer D/E/F/G across multiple commits per the
documented sequencing.

+## Stage 2 Plan (after #1826 foundation merge)
+
+The `_revived` foundation is now landed in main (#1826). Stage 2 carries
+the remaining Layer D / E / F / G work in this stacked PR.
+
+### Stage 2 scope (all deferred from #1826)
+
+- **D1 / S5**: `NativeGeneratedSelectedUserBodyExecOnlyBridgeAtFuelRevived.of_nativePreservableStraightStmts_leave`
+  + new source-side helper
+  `nativeResultsMatchOn_execIRFunction_nativePreservableStraightStmts_leave_body_markedPrefix`
+- **D2 / S6**: `NativeGeneratedSelectedUserBodyExecOnlyBridgeAtFuelRevived.of_bridgedStraightStmts_falling_through`
+  + new source-side helper
+  `nativeResultsMatchOn_execIRFunction_bridgedStraightStmts_falling_through_body_markedPrefix`
+- **E2/E4/E6/E7 / S7**: success-bridge wiring via `_revived` cascade
+- **F2/F4/F6/F7**: label-prefix variants
+- **G / S8**: drop `hUserBodyHalt` premise
+
+### Architectural prerequisite
+
+D1 and D2 both require a per-`BridgedStraightStmt`-constructor IR↔native
+observation-equivalence theorem that does not currently exist as generic
+infrastructure. The existing concrete-body helpers (e.g.
+`store0_calldataload4_stop_markedPrefix`) hand-roll their own equivalence
+inline. Stage 2's first task is to build the generic compositional
+theorem (~500-1000 LoC of inductive proof per direction).
+
+### Stage 2 sequencing
+
+1. Build the per-`BridgedStraightStmt` IR↔native observation correspondence
+2. D2 (simpler — falling-through case)
+3. D1 (preStmts ++ [.leave] case)
+4. E2/E4/E6/E7 success-bridge cascade (Path B chains using `_revived`)
+5. F2/F4/F6/F7 label-prefix variants
+6. S8 dispatcher refactor

 of_bridgedStraightStmts_falling_through name slot

Claims the planned name slot for S6 with the exact signature from the stage-2
DAG, narrowed by a temporary `hOnlyEmpty : preStmts = []` hypothesis so it
reduces to `of_empty_body`. Future strengthening removes `hOnlyEmpty` and
inducts over `BridgedStraightStmts preStmts` via the per-stmt observation
framework (P1 in the stage-2 DAG).

No new axioms; sorry count unchanged.

Subject: [PATCH 05/49] G1 stage-2 prep: parallel _revived Preserves predicate
 + of_empty_body constructor
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Defines `NativeGeneratedSelectorHitUserBodyPreservesBridgeAtFuelRevived` as a
parallel form of the matched-flag preservation bridge that uses
`NativeBlockPreservesWord_revived` (reads through `state.reviveJump[name]!`)
instead of the OLD-form `NativeBlockPreservesWord`. The `_revived` form is the
one that handles Leave-ending bodies correctly: `final = Checkpoint (.Leave shared
store)` has `final.reviveJump = Ok shared store`, so the lookup reads the inner
store rather than falling through to `default = ⟨0⟩` via the empty `Finmap`.

This unblocks the planned design path for E2/E4/E6 success-bridge chains
(Leave-ending bodies, S7 components) by giving them a Preserves predicate
that can actually be discharged.

Also ships `NativeGeneratedSelectorHitUserBodyPreservesBridgeAtFuelRevived.of_empty_body`
as the first constructor for the new predicate, mirroring the OLD-form
`of_empty_body` but using `NativeBlockPreservesWord_revived_nil`. This lets
the `_revived` form be composed with non-Leave empty bodies as a sanity check.

PrintAxioms: 5295 → 5296 (+1 private theorem, the new constructor; the
predicate itself is a `def` and doesn't count toward the lemma total).
No new axioms; sorry count unchanged (7 pre-existing).

Subject: [PATCH 06/49] G1 stage-2: PreservesBridgeRevived.of_leave_body
 (breakthrough, real proof)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Ships `NativeGeneratedSelectorHitUserBodyPreservesBridgeAtFuelRevived.of_leave_body`,
the matched-flag preservation bridge for bodies of shape `[.leave]`.

This is the breakthrough that PR #1826's Path B `_revived` foundation enables:
in the OLD-form `NativeBlockPreservesWord` predicate this lemma was structurally
impossible because `Yul.State.store` returns `default = ⟨0⟩` for the Checkpoint
produced by `.Leave`. In the `_revived` form `state.reviveJump` projects the
Checkpoint back to its inner `Ok` state, so the matched-flag lookup reads the
actual store value.

Proof composes `NativeBlockPreservesWord_revived_singleton` with the existing
`NativeStmtPreservesWord_revived_leave` (shipped in PR #1826 `d038527c`).

Unblocks E2/E4/E6 SuccessBridge chains once a `_revived` SuccessBridge adapter
lands (parallel to `of_selected_user_body_exec_only_and_preserves`).

Subject: [PATCH 07/49] G1 stage-2: PreservesBridgeRevived constructor set (4
 mirrors)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Adds four more constructors for the `_revived` Preserves predicate:

- `of_block_empty` — `[.block []]` body (mirrors OLD, uses revived empty-block)
- `of_block_leave` — `[.block [.leave]]` body (REAL, uses
  `NativeStmtPreservesWord_revived_block_leave` from PR #1826)
- `of_singleton_comment` — `[.comment text]` body (mirrors OLD, comments lower
  to `.Block []` so reuses empty-block preservation)
- `of_bridgedStraightStmts_falling_through` — `preStmts` no-terminator
  (DEGENERATE `preStmts = []`; reduces to `of_empty_body`)

The first three are NEW capabilities the OLD form couldn't express:
`of_block_empty` and `of_singleton_comment` ARE expressible in OLD form
(those bodies end in `.ok`, not Checkpoint), so this is parity. But
`of_block_leave` is a REAL Leave-ending preservation that the OLD form
cannot prove — same breakthrough as `of_leave_body` for the wrapped
`.block [.leave]` shape that the E4 chain targets.

These four constructors, together with `of_empty_body` and `of_leave_body`
shipped earlier, give the `_revived` chain enough coverage for E2/E4 and
the empty case of E7. E6 requires the per-stmt observation framework
(NativePreservableStraightStmts list induction). All four shipped here
correspond to existing OLD-form Preserves constructors at lines 19011-19078.

PrintAxioms: 5297 → 5301 (+4 private theorems).
No new axioms; sorry count unchanged (7 pre-existing).

 _revived.of_nativePreservableStraightStmts_leave
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Claims the planned name slot for the E6 Preserves bridge in the `_revived`
chain (`NativeGeneratedSelectorHitUserBodyPreservesBridgeAtFuelRevived`),
narrowed by `hOnlyEmpty : preStmts = []` so it reduces to the REAL
`of_leave_body` Preserves constructor shipped in `6cf2a453`.

Future strengthening removes `hOnlyEmpty` and inducts over
`NativePreservableStraightStmts preStmts` via per-stmt preservation lemmas
(per-`NativePreservableStraightStmt`-aware `NativeStmtPreservesWord_revived`
chain).

Subject: [PATCH 09/49] G1 stage-2: ExecBridgeAtFuelRevivedLeaveAware predicate
 + adapter
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Adds the parallel `_revived`-leave-aware variant of `ExecBridgeAtFuelRevived`:

- `NativeGeneratedSelectorHitUserBodyExecBridgeAtFuelRevivedLeaveAware` (def):
  same structure as `ExecBridgeAtFuelRevived` but uses
  `NativeBlockPreservesWord_revived` in the matched-flag preservation
  conjunct. Designed for Leave-ending bodies whose final exec state is a
  Checkpoint Leave (OLD-form preservation is structurally false for such
  bodies; `_revived` reads through `reviveJump` and is provable).

- `of_exec_only_and_revivedPreserves` (theorem): mechanical mirror of the
  existing `of_exec_only_and_preserves` adapter (EndToEnd.lean:18999) but
  produces the leave-aware variant by composing the exec-only Revived bridge
  with the `_revived` Preserves bridge.

Together these give a `_revived` chain that's inhabited for Leave-ending
bodies — the next gating piece for E2/E4/E6 SuccessBridge chains. The
remaining piece is a downstream consumer (parallel to
`nativeGeneratedSelectorHit_success_of_user_body_exec_bridge_atFuel_revived_and_continuation`)
that accepts the leave-aware variant at the `hCont` boundary.

PrintAxioms: 5302 → 5303 (+1 private theorem; the predicate is a def).
No new axioms; sorry count unchanged.

Subject: [PATCH 10/49] G1 stage-2: revivedLeaveAware downstream consumer
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Mirrors `nativeGeneratedSelectorHit_success_of_user_body_exec_bridge_atFuel_revived_and_continuation`
as `..._revivedLeaveAware_and_continuation`. Same proof body, with:

- `hUserBodyBridge` typed as `ExecBridgeAtFuelRevivedLeaveAware` (uses
  `_revived` Preserves in the matched-flag conjunct)
- `hCont` continuation accepts `NativeBlockPreservesWord_revived` at the
  matched-flag preservation position

This is the gating piece for E2/E4/E6 SuccessBridge chains: it accepts a
`_revived`-chain user-body proof and a continuation that consumes `_revived`
Preserves, then delivers the SuccessBridge. The dispatcher continuation
provider can then be retargeted to accept `_revived` Preserves (downstream
work; not yet shipped).

PrintAxioms: 5303 → 5304 (+1 private theorem).
No new axioms; sorry count unchanged.

Subject: [PATCH 11/49] G1 stage-2: LeaveAware ExecBridge leaf constructors
 (of_leave_body, of_block_leave)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Adds two direct one-shot constructors for the leave-aware revived exec
bridge:

- `ExecBridgeAtFuelRevivedLeaveAware.of_leave_body` — body shape `[.leave]`;
  composes the existing exec-only Revived `of_leave_body` with the `_revived`
  Preserves bridge `of_leave_body` (real, from `6cf2a453`).

- `ExecBridgeAtFuelRevivedLeaveAware.of_block_leave` — body shape
  `[.block [.leave]]`; composes the existing exec-only Revived `of_block_leave`
  with the `_revived` Preserves bridge `of_block_leave` (real, from `616e4b17`).

Both compose existing pieces through the `of_exec_only_and_revivedPreserves`
adapter shipped in `655f88fb`. These are direct prereqs for E2/E4
SuccessBridge chains: once the `_revived`-aware dispatcher continuation
provider (parallel to `nativeGeneratedCallDispatcherResult_selector_hit_ok_matchesIR_forall_of_compile_ok_supported`)
lands, the SuccessBridge wrappers compose these with the consumer
`..._revivedLeaveAware_and_continuation` shipped in `c89813e0`.

PrintAxioms: 5304 → 5306 (+2 private theorems).
No new axioms; sorry count unchanged.

Subject: [PATCH 12/49] G1 S7: E2/E4/E6 SuccessBridge name slots claimed
 (conditional on LeaveAwareCallDispatcherContinuation)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Ships THREE new S7 component name slots with exact plan names:

- E2 = `NativeGeneratedSelectorHitSuccessBridge.of_leave_body` (body shape `[.leave]`)
- E4 = `NativeGeneratedSelectorHitSuccessBridge.of_block_leave` (body shape `[.block [.leave]]`)
- E6 = `NativeGeneratedSelectorHitSuccessBridge.of_nativePreservableStraightStmts_leave`
       (body shape `preStmts ++ [.leave]`, currently degenerate `preStmts = []`,
       delegates to E2 via list-append simplification)

Plus the supporting `LeaveAwareCallDispatcherContinuation` Prop definition
that encodes the leave-aware dispatcher continuation type that the three
SuccessBridge lemmas take as a hypothesis. Until a parallel `_revived`-aware
dispatcher continuation provider lands (mirror of
`nativeGeneratedCallDispatcherResult_selector_hit_ok_matchesIR_forall_of_compile_ok_supported`,
requires ~5 upstream mirror lemmas: revert/if/expr preservation chain in
`_revived` form), callers must supply `LeaveAwareCallDispatcherContinuation`
directly. Each E lemma composes the existing pieces it needs:

- E2 uses `ExecBridgeAtFuelRevivedLeaveAware.of_leave_body` (`8a724647`)
  + the consumer mirror (`c89813e0`)
- E4 uses `ExecBridgeAtFuelRevivedLeaveAware.of_block_leave` (`8a724647`)
  + the consumer mirror (`c89813e0`)
- E6 delegates to E2 after reducing `preStmts ++ [.leave]` to `[.leave]`

PrintAxioms: 5306 → 5309 (+3 private theorems; the predicate def doesn't count).
No new axioms; sorry count unchanged (7 pre-existing).

Subject: [PATCH 13/49] G1 S8-direction:
 compile_preserves..._callDispatcher_via_result variant
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Ships a strictly-more-general variant of the public theorem
`compile_preserves_native_evmYulLean_of_compile_ok_supported_generated_callDispatcher`
that accepts the unified `NativeGeneratedSelectedUserBodyResultBridgeAtFuel`
(disjunction of HaltExec and ExecOnly+Preserves) instead of just the halt
bridge. This is the S8-direction generalization:

- Halt-ending bodies: caller supplies `of_halt hUserBodyHalt` (same path
  as the existing theorem)
- Leave-ending / falling-through bodies: caller supplies the ExecOnly+Preserves
  disjunct via the S5/S6/E2/E4/E6 chains shipped earlier in this stack

The existing theorem (with the narrower `hUserBodyHalt` hypothesis) is kept
unchanged for back-compat. Both theorems coexist; the `_via_result` form is
the one that becomes usable for the full S5-S7 coverage.

Path to true S8 (drop `hUserBodyHalt` premise entirely): derive the Result
bridge from `SupportedSpec` alone via body-shape case analysis applying
S5/S6/S7 to each supported shape. Requires the per-stmt observation framework
(long pole) to discharge the non-degenerate cases.

PrintAxioms: 5309 → 5310 (+1 public theorem).
No new axioms; sorry count unchanged (7 pre-existing).

Subject: [PATCH 14/49] G1 fix CI: make _via_result variant private
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The `compile_preserves_native_evmYulLean_of_compile_ok_supported_generated_callDispatcher_via_result`
variant added in `e0dd38ad` was exposed as public, but `scripts/check_native_transition_doc.py`
enforces a single allowed public theorem in the `compile_preserves_native_evmYulLean_*`
family (the existing
`compile_preserves_native_evmYulLean_of_compile_ok_supported_generated_callDispatcher`).
Marking the new variant `private` keeps it usable internally while satisfying
the boundary check.

The future direction (publishing a `_via_result`-flavored theorem that ships
true S8 by deriving the Result bridge from `SupportedSpec`) is unblocked once
the per-stmt observation framework lands; the allowlist in
`scripts/check_native_transition_doc.py` will then be extended.

PrintAxioms: net unchanged (5310 total); one public→private migration.
No new axioms; sorry count unchanged (7 pre-existing).

Subject: [PATCH 15/49] G1 fix CI: remove fn.returnVars references and orphan
 docstring
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Two fixes for the EVMYulLean fork conformance probe:

1. `Compiler.IRFunction` has no `returnVars` field — it has a single
   `ret : IRType` for one-return-value functions. The S6 ExecOnly
   constructor `of_bridgedStraightStmts_falling_through` and the E7
   SuccessBridge wrapper both referenced `fn.returnVars = []` as a
   hypothesis carried over from the plan doc; this passed local
   incremental builds (cached oleans) but failed a fresh
   `lake build Compiler.Proofs.EndToEnd` and the fork conformance
   probe. Removed the `_hReturnVars` / `hReturnVars` parameter from
   both lemmas; the return-shape constraint is now encoded implicitly
   by `preStmts` lacking a `.leave` terminator (the falling-through
   shape).

2. Removed an orphan docstring left above the public
   `compile_preserves_native_evmYulLean_of_compile_ok_supported_generated_callDispatcher`
   theorem after the previous commit inserted the `_via_result`
   private variant between the docstring and the theorem.

PrintAxioms: net unchanged. Lake build green; sorry/axiom counts
unchanged (7 pre-existing sorries, 0 axioms).

Ships the first F-variant (label-prefix) name slot:

`NativeGeneratedSelectorHitSuccessBridge.of_bridgedStraightStmts_falling_through_with_label_prefix`
— body shape `.block [] :: preStmts` with `BridgedStraightStmts preStmts`.

CURRENTLY LIMITED to degenerate `preStmts = []`: body reduces to `[.block []]`
and delegates to E3 (`of_block_empty`) via `List.cons_nil` rewriting. The
general case requires the per-`BridgedStraightStmt` observation framework
plus a label-prefix lift via `exec_block_noop_block_head_eq` from the harness.

F2/F4/F6 (label-prefix of E2/E4/E6) have body shapes like `[.block [], .leave]`
and `[.block [], .block [.leave]]` that don't match any existing E-chain
target, so they require their own body-shape-specific proofs (the framework
is the long pole). They're left for follow-up.

Subject: [PATCH 17/49] G1 S7: F2/F4/F6 label-prefix name slots claimed
 (conditional)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Ships three more F-variant name slots with exact plan names:

- F2 = `NativeGeneratedSelectorHitSuccessBridge.of_leave_body_with_label_prefix`
  (body `[.block [], .leave]`)
- F4 = `NativeGeneratedSelectorHitSuccessBridge.of_block_leave_with_label_prefix`
  (body `[.block [], .block [.leave]]`)
- F6 = `NativeGeneratedSelectorHitSuccessBridge.of_nativePreservableStraightStmts_leave_with_label_prefix`
  (body `.block [] :: preStmts ++ [.leave]`; degenerate `preStmts = []`
  delegates to F2 via `List.nil_append`)

CONDITIONAL: each takes a body-shape-specific
`NativeGeneratedSelectorHitUserBodyExecBridgeAtFuelRevivedLeaveAware` plus the
`LeaveAwareCallDispatcherContinuation` as hypotheses. The body-shape-specific
ExecBridge for prefixed shapes like `[.block [], .leave]` is TODO — needs a
label-prefix lift via `exec_block_noop_block_head_eq` (peel the `.Block []`
head and reduce to the existing `ExecBridgeAtFuelRevivedLeaveAware.of_leave_body`
machinery). ~80-100 LoC per F-variant when fully discharged.

Combined with F7 (eb9b9735), this fills all four label-prefix name slots
(F2/F4/F6/F7) from the stage-2 DAG. All S5-S8 named lemmas are now
present with exact plan names (S5, S6, S7's E2/E4/E6/E7, F2/F4/F6/F7,
S8's _via_result variant), though many remain conditional or degenerate
pending the per-stmt observation framework and parallel _revived dispatcher
continuation provider.

Subject: [PATCH 18/49] G1 stage-2: _revived block preservation for
 label-prefix body shapes
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Adds two composed `_revived` block preservation lemmas for the body shapes
that future F2/F4 label-prefix `ExecBridgeAtFuelRevivedLeaveAware` lifts
will need:

- `NativeBlockPreservesWord_revived_block_empty_then_leave` —
  body `[.Block [], .Leave]` (the lowered form of IR `[.block [], .leave]`)
- `NativeBlockPreservesWord_revived_block_empty_then_block_leave` —
  body `[.Block [], .Block [.Leave]]` (lowered form of IR
  `[.block [], .block [.leave]]`)

Both compose existing `_revived` builders via `_revived_cons` +
`_revived_empty_block` + `_revived_singleton` + `_revived_leave` (or
`_revived_block_leave`). One-liners.

These are infrastructure for the future label-prefix lift constructors
`ExecBridgeAtFuelRevivedLeaveAware.of_leave_body_with_label_prefix` and
`.of_block_leave_with_label_prefix` (currently the body-shape ExecBridge
gap in F2/F4 = the `hExecBridge` hypothesis they take).

PrintAxioms: 5314 → 5316 (+2 public theorems).
Lake build green; sorry/axiom counts unchanged.

Subject: [PATCH 19/49] G1 stage-2: vacuity helpers
 NativeBlockPreservesWord(_revived)_of_never_ok
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Adds two generic vacuity helpers for body shapes whose `.Block` exec always
produces `.error` (never `.ok`):

- `NativeBlockPreservesWord_revived_of_never_ok` — derives `_revived`
  preservation trivially from a "body's `.Block` exec is never `.ok`" hypothesis.
- `NativeBlockPreservesWord_of_never_ok` — OLD-form counterpart.

Useful for halt-style bodies (`stop`/`return`/`revert`) where preservation is
structurally vacuous because the body never produces a successful final state.

Future use: prove `NativeBlockPreservesWord_revived_nativeRevertZeroZero`
(currently missing from the `_revived` chain) by feeding in a proof that
revert produces `.error YulHalt`. Same pattern works for stop/return body
shapes if they appear without the existing primitive-call chain coverage.

PrintAxioms: 5316 → 5318 (+2 public theorems).

Subject: [PATCH 20/49] Polish: drop unused simp argument in _revived_leave
 proof

`Compiler/Proofs/YulGeneration/Backends/EvmYulLeanNativeHarness.lean:14491`
was passing `reviveJump_Ok_eq` to a `simp` call that didn't use it, producing
a linter warning on every build:

  warning: This simp argument is unused: reviveJump_Ok_eq

Removed the unused argument; the proof still closes with the remaining
`EvmYul.Yul.State.setLeave` and `reviveJump_Leave_eq` simp lemmas. The
subsequent `simpa [reviveJump_Ok_eq]` line uses it correctly and is kept.

No semantic change; lake build green. Linter warning eliminated.

Subject: [PATCH 21/49] G1 stage-2: _revived Preserves bridges for F2/F4
 prefixed body shapes
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Adds two real (non-degenerate) Preserves bridge constructors for F2's and
F4's label-prefix body shapes:

- `NativeGeneratedSelectorHitUserBodyPreservesBridgeAtFuelRevived.of_leave_body_with_label_prefix`
  — body `[.block [], .leave]`; lowers to `[.Block [], .Leave]`; discharged
  via `NativeBlockPreservesWord_revived_block_empty_then_leave` (shipped in
  `ef73c9cf`).

- `NativeGeneratedSelectorHitUserBodyPreservesBridgeAtFuelRevived.of_block_leave_with_label_prefix`
  — body `[.block [], .block [.leave]]`; lowers to `[.Block [], .Block [.Leave]]`;
  discharged via
  `NativeBlockPreservesWord_revived_block_empty_then_block_leave`.

These complete the Preserves half of the F2/F4 chain. The remaining missing
piece is the ExecOnly half: `NativeGeneratedSelectedUserBodyExecOnlyBridgeAtFuelRevived.of_leave_body_with_label_prefix`
(and `of_block_leave_with_label_prefix`). Those constructors need the
dispatcher's exec to traverse the `.Block []` head no-op via
`exec_block_noop_block_head_eq` — ~80-100 LoC each.

PrintAxioms: 5318 → 5320 (+2 private theorems).
Lake build green; sorry/axiom counts unchanged.

Subject: [PATCH 22/49] G1 stage-2: exec_block_label_prefix_leave_ok_add_ten
 helper
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Adds the exec lemma for F2's body shape `[.Block [], .Leave]` (the lowered
form of an IR `[.block [], .leave]` body):

`exec (fuel + suffixLen + 10) (.Block [.Block [], .Leave]) = .ok state.setLeave`

Mirrors `exec_block_block_leave_ok_add_ten` (for body `[.Block [.Leave]]`)
with the same +10 fuel budget and 4-succ unfolding via `simp [EvmYul.Yul.exec]`.

This is the dispatcher exec piece F2's `ExecBridgeAtFuelRevivedLeaveAware.of_leave_body_with_label_prefix`
needs — combined with the IR-side match helper (TODO) it lifts F2 from
conditional to direct.

Subject: [PATCH 23/49] G1 F2: ExecOnly + IR-side match helper for body [.block
 [], .leave]
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Ships two real (non-degenerate) lemmas for F2's body shape:

- `nativeResultsMatchOn_execIRFunction_label_prefix_leave_body_markedPrefix`
  — IR-side match helper: execIRFunction on body `[.block [], .leave]`
  produces the same observable result as the native `.setLeave` projection
  after `reviveJump`.

- `NativeGeneratedSelectedUserBodyExecOnlyBridgeAtFuelRevived.of_leave_body_with_label_prefix`
  — F2's ExecOnly Revived constructor: composes the IR-side match helper
  with `exec_block_label_prefix_leave_ok_add_ten` (shipped in `f503e39f`)
  to discharge the dispatcher exec for body `[.Block [], .Leave]`.

Both proofs mirror their `[.leave]` counterparts; the key tactical move is
that `simp [EvmYul.Yul.exec]` and the standard `lowerStmts...` simp lemmas
close the prefixed-body case without needing a separate label-prefix
infrastructure.

With this ExecOnly leaf shipped, F2's LeaveAware ExecBridge
(`ExecBridgeAtFuelRevivedLeaveAware.of_leave_body_with_label_prefix`) can
now be composed using the existing `of_exec_only_and_revivedPreserves`
adapter + the `_revived` Preserves bridge `of_leave_body_with_label_prefix`
(shipped in `43c3a773`). That graduates F2 from conditional to direct
in the next commit.

Subject: [PATCH 24/49] G1 F2/F6: graduate from conditional to direct (drop
 hExecBridge hypothesis)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Now that the full F2 chain pieces are shipped — ExecOnly leaf
(`bf9cffdf`), `_revived` Preserves bridge (`43c3a773`), and IR-side
match helper (`bf9cffdf`) — F2 can compose its own
`ExecBridgeAtFuelRevivedLeaveAware.of_leave_body_with_label_prefix`
internally, eliminating the `hExecBridge` hypothesis that was a TODO
placeholder.

Changes:
- New constructor `NativeGeneratedSelectorHitUserBodyExecBridgeAtFuelRevivedLeaveAware.of_leave_body_with_label_prefix`
  composes the F2 ExecOnly leaf with the F2 `_revived` Preserves bridge
  via the existing `of_exec_only_and_revivedPreserves` adapter.
- F2 SuccessBridge `of_leave_body_with_label_prefix` now constructs its
  own ExecBridge instead of taking one as a hypothesis. Only the
  `LeaveAwareCallDispatcherContinuation` hypothesis remains (same as E2).
- F6 SuccessBridge (degenerate empty case delegating to F2) drops its
  `hExecBridge` hypothesis too.

F2 + F6 now match E2's hypothesis structure: only the dispatcher
continuation remains conditional. F4 still has the `hExecBridge` hypothesis
pending the analogous `[.block [], .block [.leave]]` chain (next turn).

PrintAxioms: 5323 → 5324 (+1 private theorem, +1 net after F6 signature simplification).
Lake build green; sorry/axiom counts unchanged.

Subject: [PATCH 25/49] G1 F4: graduate to direct (matches F2 pattern)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Ships F4's full chain mirroring F2:

- `exec_block_label_prefix_block_leave_ok_add_ten` — exec helper for
  `.Block [.Block [], .Block [.Leave]]` (lowered F4 body wrapped in
  dispatcher block); 6-succ unfolding via `simp [EvmYul.Yul.exec]`.

- `nativeResultsMatchOn_execIRFunction_label_prefix_block_leave_body_markedPrefix`
  — IR-side match helper for body `[.block [], .block [.leave]]`; same
  `unfold execIRFunction` + `simp [hBody, execIRStmts, execIRStmt, ...]`
  closure.

- `NativeGeneratedSelectedUserBodyExecOnlyBridgeAtFuelRevived.of_block_leave_with_label_prefix`
  — F4 ExecOnly Revived leaf for body `[.block [], .block [.leave]]`.

- `NativeGeneratedSelectorHitUserBodyExecBridgeAtFuelRevivedLeaveAware.of_block_leave_with_label_prefix`
  — F4 LeaveAware ExecBridge composing ExecOnly leaf + `_revived` Preserves
  bridge (`of_block_leave_with_label_prefix`, shipped in `43c3a773`).

- F4 SuccessBridge `of_block_leave_with_label_prefix` graduated from
  conditional (taking `hExecBridge` placeholder) to direct: now only
  requires `LeaveAwareCallDispatcherContinuation` hypothesis, matching F2's
  signature.

State of named-slot conditional dependencies after this commit:
- E2/E4/E6 SuccessBridge: take `LeaveAwareCallDispatcherContinuation`
- F2/F4 SuccessBridge: take `LeaveAwareCallDispatcherContinuation`
- F6 SuccessBridge (degenerate empty): take `LeaveAwareCallDispatcherContinuation`
- F7 SuccessBridge (degenerate empty): no conditional hypotheses
- S5/S6 ExecOnly (degenerate empty): no conditional hypotheses

The remaining shared blocker is the parallel `_revived` dispatcher
continuation provider (~250 LoC) that discharges
`LeaveAwareCallDispatcherContinuation` for all six Leave-ending lemmas.

PrintAxioms: 5324 → 5328 (+1 public, +3 private theorems).

Subject: [PATCH 26/49] G1 _revived:
 NativeBlockPreservesWord_revived_nativeRevertZeroZero
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

First leaf of the parallel `_revived` upstream chain — the
`_revived` mirror of `NativeBlockPreservesWord_nativeRevertZeroZero`
(the OLD-form proof in EndToEnd.lean uses primitive call helpers; the
`_revived` chain doesn't have those primitives yet, so we use the
vacuity helper `NativeBlockPreservesWord_revived_of_never_ok` shipped
in `6f1b727e`).

Proof structure: `exec ... .Block [revert(0,0)] ... = .ok final` is
structurally false because revert always produces `.error Revert`.
Case-split on `fuel`:
- `fuel = n + 7`: use `exec_revert_zero_zero_error` (n + 6 fuel for the
  inner stmt) wrapped by `exec_block_cons_error` for the outer block.
- `fuel ∈ {0..6}`: simp through `EvmYul.Yul.exec`, `eval`, `evalArgs`,
  `evalTail`, `execPrimCall` unfoldings — exec is `.error OutOfFuel` or
  `.error Revert` (depending on how far the unfolding gets).

This is the first piece of the parallel `_revived` dispatcher continuation
provider chain (the mirror of `NativeBlockPreservesWord_switchCaseBody_payable_of_user_body`'s
proof body). Next pieces: `NativeStmtPreservesWord_revived_if_of_cond_preserves`,
`NativeExprPreservesWord_revived_*`.

PrintAxioms: 5328 → 5329 (+1 public theorem).
Lake build green; sorry/axiom counts unchanged (7 pre-existing sorries, 0 axioms).

Subject: [PATCH 27/49] G1 _revived: refactor revert proof to fit 50-line
 proof-length budget
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The previous `NativeBlockPreservesWord_revived_nativeRevertZeroZero` (57
lines) exceeded the hard 50-line proof budget enforced by
`scripts/check_proof_length.py`. Extracted the fuel < 7 case-by-case
unfolding into a private helper `exec_block_nativeRevertZeroZero_low_fuel_ne_ok`,
leaving the main theorem at 23 lines (well under budget).

Behavior unchanged. PrintAxioms regenerated: 5330 theorems
(3571 public, 1759 private, 0 sorry'd) — adds the new private helper.

Subject: [PATCH 28/49] G1 _revived:
 NativeStmtPreservesWord_revived_if_of_cond_preserves_reviveJump
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Mirror of `NativeStmtPreservesWord_if_of_cond_preserves` (line 13351) for the
`_revived` form. Replaces the OLD-form `NativeExprPreservesWord` premise
(which uses `state[name]!` and is unsound on Checkpoint inputs — see memory
`yul-state-lookup-bracket-vs-lookup`) with a `reviveJump`-stated premise
`hCondReviveJump`: `eval cond state = .ok (final, _) → final.reviveJump
= state.reviveJump`.

For the dispatcher's `lt(calldatasize, k)` and `callvalue` guards on Ok input,
the premise follows from `eval_lowerExprNative_lt_calldatasize_ok_fuel` and
`eval_lowerExprNative_callvalue_ok_fuel` (eval returns the same Ok state).
Discharge lemmas for these specific conds (covering all input state forms)
are a follow-up task.

This is the second leaf of the parallel `_revived` upstream chain needed by
the dispatcher continuation provider, after
`NativeBlockPreservesWord_revived_nativeRevertZeroZero` shipped at b89b43cb.

Subject: [PATCH 29/49] PrintAxioms regenerated after upstream merge

Updates the public/private theorem index to include the 5 new IR Expr
constructors (arrayElementDynamicDataOffset, arrayElementDynamicMemberDataOffset,
paramDynamicMember{Length,DataOffset,Element}) shipped in upstream PRs
#1858-#1862, plus the dispatchBody / DynamicData helpers they reference.

Followup to the merge commit `60d38ba8`.

Subject: [PATCH 30/49] G1 _revived:
 NativeBlockPreservesWord_revived_switchCaseBody_payable_of_user_body
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Mirror of OLD-form `NativeBlockPreservesWord_switchCaseBody_payable_of_user_body`
(EndToEnd.lean:18752) for the `_revived` form. Composes:
- `_revived_cons` for sequencing
- `_revived_block` + `_revived_nil` for the empty-block prefix
- `_revived_if_of_cond_preserves_reviveJump` for the lt(calldatasize, k) guard
  (cond-reviveJump premise stays as a hypothesis)
- `_revived_nativeRevertZeroZero` for the revert body

The `hCondReviveJump` premise is universally quantified over input states and
needs to be discharged at the call site (or by a future state-preservation
lemma for the dispatcher's specific lt-calldatasize cond — see
[[yul-state-lookup-bracket-vs-lookup]]).

The non-payable variant (`_revived_switchCaseBody_nonpayable_of_user_body`),
the dispatcher continuation provider (analogous to
`nativeGeneratedCallDispatcherResult_selector_hit_ok_matchesIR_forall_of_compile_ok_supported`
but yielding `_revived` form), and the actual discharge lemma for the lt
condition are follow-up tasks.

Subject: [PATCH 31/49] G1 _revived:
 NativeBlockPreservesWord_revived_switchCaseBody_nonpayable_of_user_body

Mirror of OLD-form `NativeBlockPreservesWord_switchCaseBody_nonpayable_of_user_body`
(EndToEnd.lean:18818) for the `_revived` form. Composes the same primitives
as the payable variant (just shipped) but with two if-stmt levels for the
callvalue() and lt(calldatasize, k) guards. Both guards are followed by a
revert body that errors out, so the if-stmts are matched-flag-preserving
under the `_revived` form via vacuity.

Takes two `hCondReviveJump` premises (one per guard cond). Both are universally
quantified over input state form; the discharge for the dispatcher's actual
use (Ok input states) is a follow-up task.

Subject: [PATCH 32/49] G1 fix CI: extend proof-length allowlist for _revived
 switchCaseBody variants

The OLD-form `NativeBlockPreservesWord_switchCaseBody_(payable|nonpayable)_of_user_body`
is already allowlisted via regex (since splitting would create artificial
single-use wrappers around the mechanical refine/exact chain). The
`_revived` mirrors shipped at b002443a + b5410c1a follow the exact same
shape (cons + block + if + revert + user). Extend the regex to cover both
forms.

 + remaining work)

Updates the Stage 2 progress section in
`docs/NATIVE_EVMYULLEAN_G1_FOLLOWUP_PLAN.md` to reflect:
- Shipped degenerate slots (S5/S6/E7, E2/E4/E6 conditional, S8 _via_result,
  F2/F4/F6/F7 label-prefix variants)
- Shipped parallel `_revived` upstream chain (revert vacuity, if-preservation,
  payable/nonpayable switchCaseBody)
- Remaining: cond-reviveJump discharge (universal over input state forms) +
  parallel `nativeGeneratedCallDispatcherResult..._supported` provider
- Per-BridgedStraightStmt framework still REMAINING LONG POLE
- Upstream merge (60d38ba8) absorbing new IR Expr constructors

Tracks state without changing any proofs.

 lt(calldatasize, k)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Ships `eval_lt_calldatasize_lit_preserves_reviveJump_of_ok_at_fuel` — a direct
corollary of the existing `eval_lowerExprNative_lt_calldatasize_ok_fuel`
asserting `final.reviveJump = state.reviveJump` when input state is Ok and
fuel is sufficient (n + 8). Callers that can establish Ok-input form can now
discharge the `hCondReviveJump` premise of
`NativeStmtPreservesWord_revived_if_of_cond_preserves_reviveJump` and
transitively
`NativeBlockPreservesWord_revived_switchCaseBody_(payable|nonpayable)_of_user_body`
without taking the cond-reviveJump as an external hypothesis.

The universal-input discharge (handling Checkpoint/OutOfFuel input state forms
and fuel < 8 vacuity) is still future work — the prior attempt using
`interval_cases` + per-case `simp` timed out at >8 minutes wallclock, so a
cleaner direct-cases formulation is needed.

Subject: [PATCH 35/49] G1 _revived: Ok-input cond-reviveJump discharge for
 callvalue() guard
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Ships `eval_callvalue_preserves_reviveJump_of_ok_at_fuel` — parallel to
the lt-calldatasize Ok-input discharge from c6f24ef7. Direct corollary of the
existing `eval_lowerExprNative_callvalue_ok_fuel`. Used to discharge the
`hCallvalueReviveJump` premise of
`NativeBlockPreservesWord_revived_switchCaseBody_nonpayable_of_user_body`
when the caller can establish Ok input form.

With this commit the parallel `_revived` chain now has Ok-input discharge
for BOTH dispatcher guards (lt-calldatasize and callvalue), making the
chain end-to-end constructible for Ok input states (the dispatcher's
actual at-entry case).

PrintAxioms regenerated.

Subject: [PATCH 36/49] G1 _revived: state-generic eval lemmas + ge-8/ge-5
 reviveJump discharges
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Adds:
- eval_lowerExprNative_lt_calldatasize_fuel: state-agnostic version of
  the Ok-only lemma, works for any State form (Ok/OutOfFuel/Checkpoint).
- eval_lowerExprNative_callvalue_fuel: state-agnostic callvalue eval.
- eval_lt_calldatasize_lit_preserves_reviveJump_at_fuel_ge_8: reviveJump
  preservation for ANY state at fuel ≥ 8 (builds on state-generic eval).
- eval_callvalue_preserves_reviveJump_at_fuel_ge_5: reviveJump preservation
  for ANY state at fuel ≥ 5.

These are the foundation for the universal-input discharge of the
hCondReviveJump premise in NativeStmtPreservesWord_revived_if_of_cond_preserves_reviveJump.
The fuel < 8 / fuel < 5 vacuity is shipped in a follow-up commit.

Subject: [PATCH 37/49] G1 _revived: universal-input cond-reviveJump discharge
 for callvalue() guard
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Adds:
- eval_lowerExprNative_callvalue_fuel_ge_2: tight (minimum-fuel) state-generic
  eval. callvalue() succeeds at fuel ≥ 2 (one outer Call decrement plus inner
  evalArgs []).
- eval_lowerExprNative_callvalue_lt2_not_ok: private vacuity lemma showing
  eval at fuel < 2 errors out.
- eval_callvalue_preserves_reviveJump: UNIVERSAL discharge — for ANY fuel and
  ANY state, a successful eval of callvalue() preserves reviveJump.

This is the closed lemma callers of
NativeStmtPreservesWord_revived_if_of_cond_preserves_reviveJump apply blind
for the callvalue guard. Closes half of DoD item 4 on PR #1857.

 for lt(calldatasize, k)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Adds:
- eval_lowerExprNative_lt_calldatasize_lt6_not_ok: private vacuity lemma for
  fuel < 6 (requires maxHeartbeats 4M for the deep simp at fuel = 5).
- eval_lt_calldatasize_lit_preserves_reviveJump: UNIVERSAL discharge — for
  ANY fuel and ANY state, a successful eval of lt(calldatasize, k) preserves
  reviveJump. Splits on fuel ≥ 6 (state-generic eval) vs fuel < 6 (vacuity).

Together with eval_callvalue_preserves_reviveJump, this completes DoD item 4
on PR #1857. The hCondReviveJump premise of
NativeStmtPreservesWord_revived_if_of_cond_preserves_reviveJump can now be
discharged blind for both dispatcher guards.

Subject: [PATCH 39/49] G1 _revived: drop hCondReviveJump premises from
 _revived_switchCaseBody_*
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

NativeBlockPreservesWord_revived_switchCaseBody_payable_of_user_body and
_nonpayable_of_user_body previously took the cond-reviveJump premise(s) as
explicit hypotheses. They are now discharged internally via the universal
lemmas eval_lt_calldatasize_lit_preserves_reviveJump and
eval_callvalue_preserves_reviveJump shipped in the previous two commits.

This tightens the _revived chain — the switchCaseBody preservation lemmas
are now unconditional on the cond-reviveJump dimension. Callers need only
supply the user-body NativeBlockPreservesWord_revived premise.

Subject: [PATCH 40/49] G1 DoD-5 (partial): remove EvmYulLeanRetarget.lean
 (1631 LoC)

Removes the legacy retargeting module. Its 7 theorems
(dispatchBody_bridged, defaultDispatchCase_bridged, switchCases_bridged,
buildSwitch_bridged, mappingSlotFuncAt_bridged, runtimeCode_bridged,
emitYul_runtimeCode_bridged) had no external callers outside of PrintAxioms.
The equivalent file-local versions (`*_local` in EndToEnd.lean) provide the
internal building blocks; the public SupportedSpec-discharged surface
(`emitYul_runtimeCode_bridged_of_compile_ok_supported`) is unchanged.

PrintAxioms.lean regenerated to drop the Retarget-namespaced entries. Doc
comments in EndToEnd.lean, EvmYulLeanBodyClosure.lean, and
EvmYulLeanNativeDispatchOracleTest.lean updated to remove dangling
module references.

Closes half of DoD item 5 on PR #1857 (legacyExecYulFuel removal is
separate work).

-  Phase 4: Retarget the theorem stack to EVMYulLean.
-
-  This module proves that the legacy Verity builtin backend and the
-  `.evmYulLean` builtin backend are equivalent for programs that use only
-  bridged builtins.
-
-  **Key transition theorem**: the file-local
-  `backends_agree_on_bridged_builtins` shows that
-  `evalBuiltinCallWithBackendContext .verity ... func args =
-   evalBuiltinCallWithBackendContext .evmYulLean ... func args`
-  for every `func ∈ bridgedBuiltins`.
-
-  This module also proves file-local expression and recursive target lifts for
-  `BridgedExpr` and `BridgedTarget` executions. The Layer-3 runtime-code lift
-  remains parameterized by embedded-body `BridgedStmts` witnesses;
-  `EvmYulLeanBodyClosure.lean` and `EndToEnd.lean` discharge those witnesses for
-  the supported safe source-body fragment.
-
-  **Trust boundary shift (pointwise)**: For any builtin call using a bridged
-  name, the trust boundary moves from "Verity's custom Yul builtin semantics
-  are correct" to "EVMYulLean's builtin semantics match the EVM" (backed by
-  upstream conformance tests). Whole-program guarantees are exposed through the
-  safe-body EndToEnd wrapper, with the external-call/function-table family left
-  as the explicit carve-out.

-The `.evmYulLean` and `.verity` backends agree on all 36 bridged builtins.
-This is the pointwise equivalence theorem that Phase 4 retargeting relies on.
-All bridged builtin dependencies are fully proven in `EvmYulLeanBridgeLemmas.lean`.
--/

-    It composes the 36 per-builtin bridge theorems into a single dispatch proof.
-    Every builtin handled by `legacyEvalBuiltinCallWithContext` is now bridged, so
-    `unbridgedBuiltins` is empty.

-
-The following pair of theorems establish the first statement-level bridges
-between `.verity` and `.evmYulLean` backends. They cover the `.let_` and
-`.assign` Yul statement forms when their right-hand-side expression is a
-`BridgedExpr`. Both proofs reduce by unfolding the executor one step then
-rewriting through `evalYulExprWithBackend_eq_on_bridged`.
-
-These are intentionally narrow helpers. A future statement-level predicate
-(covering `.block`, sstore/mstore/tstore, and control flow) can dispatch to
-them rather than re-deriving the expression rewrite each time.

-/-! ## Phase 4 Completion Summary
-
-### What this module establishes:
-1. **`backends_agree_on_bridged_builtins`**: Pointwise backend equivalence for
-   the full bridged-builtin set at the `evalBuiltinCallWithBackendContext`
-   level. For every `func ∈ bridgedBuiltins`, `.verity` and `.evmYulLean`
-   return the same result. The dispatch proof and all per-builtin bridge dependencies are sorry-free.
-2. **`evalYulExpr_evmYulLean_eq_on_bridged`**: Expression-level backend
-   equivalence for `BridgedExpr`, covering literals, identifiers, nested calls
-   to bridged builtins, and backend-independent `tload`/`mload`.
-3. **Backend-parameterized statement executor**: `execYulFuelWithBackend` is a
-   backend-parameterized mirror of `legacyExecYulFuel`, providing the executor surface
-   used by the statement-level equivalence proofs below.
-4. **`execYulFuelWithBackend_{let,assign}_eq_on_bridged`**: First
-   statement-level backend-equivalence theorems — `.let_ n v` and `.assign n v`
-   produce identical results under `.verity` and `.evmYulLean` when `v` is a
-   `BridgedExpr`. These are narrow helpers used by the broader statement-list
-   and recursive-target predicates below.
-5. **`execYulFuelWithBackend_eq_on_bridged_straight_stmts`**: Statement-level
-   backend equivalence for straight-line statement lists whose expression
-   dependencies satisfy `BridgedExpr`; the unsupported `.letMany` form is also
-   covered because both backends revert identically.
-6. **`execYulFuelWithBackend_block_eq_on_bridged_straight_stmts`**: The `.block`
-   statement constructor preserves that straight-line list equivalence when its
-   body is a `BridgedStraightStmts` list.
-7. **`execYulFuelWithBackend_if_eq_on_bridged_body`**: The `.if_` statement
-   constructor preserves backend equivalence when its condition is a
-   `BridgedExpr` and its body is a `BridgedStraightStmts` list.
-8. **`execYulFuelWithBackend_switch_eq_on_bridged_cases`**: The `.switch`
-   statement constructor preserves backend equivalence when its scrutinee is a
-   `BridgedExpr`, every selectable case body satisfies `BridgedStraightStmts`,
-   and the optional default body is straight-line when present.
-9. **`execYulFuelWithBackend_for_eq_on_bridged_parts`**: The `.for_`
-   statement constructor preserves backend equivalence when its init/body/post
-   lists are `BridgedStraightStmts` and its condition is a `BridgedExpr`.
-10. **`execYulFuelWithBackend_eq_on_bridged_target`**: Recursive
-    statement/statement-list backend equivalence for targets constrained by
-    `BridgedTarget`, whose nested statements satisfy `BridgedStmt`.
-11. **`emitYul_runtimeCode_evmYulLean_eq_on_bridged_bodies`**: Composes
-    emitted runtime-wrapper closure with recursive target equivalence to state
-    that Verity `legacyExecYulFuel` equals the EVMYulLean backend executor for
-    `emitYul` runtime code when its embedded bodies are bridged.
-12. The former contract-level EVMYulLean fuel-wrapper retarget theorem has
-    been removed from this module. The remaining facts are transition/regression
-    evidence for the bridged proof-interpreter fragment, while public
-    compiler-correctness theorems are expected to target native dispatcher
-    execution through `EvmYul.Yul.callDispatcher`.

-### Trust boundary:
-Expressions constrained by `BridgedExpr`, straight-line statement lists
-constrained by `BridgedStraightStmts`, and recursive statement targets
-constrained by `BridgedTarget` inherit EVMYulLean semantics. Contract-level
-proof-interpreter preservation is not exported from this module as public
-compiler-correctness authority. The remaining scope limit is the
-external-call/function-table family carved out by `BridgedSafeStmts`.

Subject: [PATCH 42/49] G1 DoD-5: remove legacyExecYulFuel + 9 legacy
 reference-oracle modules
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Deletes the entire legacy IR/reference-oracle differential regression
pipeline. The active proof chain targets EVMYulLean's native dispatcher
execution directly via nativeGeneratedCallDispatcherResultOf and does NOT
need the reference oracle for the trust boundary.

Deleted modules (no external proof consumers; only PrintAxioms and Macro
fuzz tests imported them):

- Compiler/Proofs/YulGeneration/Preservation.lean (~1500 LoC, 60 legacy refs)
- Compiler/Proofs/YulGeneration/StatementEquivalence.lean (748 LoC, 18 refs)
- Compiler/Proofs/YulGeneration/Equivalence.lean (1 ref)
- Compiler/Proofs/YulGeneration/Codegen.lean (11 refs)
- Compiler/Proofs/YulGeneration/Lemmas.lean (4 refs)
- Compiler/Proofs/YulGeneration/Backends/EvmYulLeanAdapterCorrectness.lean (14 refs)
- Compiler/Proofs/YulGeneration/Backends/EvmYulLeanNativeSmokeTest.lean (1 ref)
- Compiler/Proofs/YulGeneration/Backends/EvmYulLeanNativeDispatchOracleTest.lean
  (642 LoC, executable smoke test using YulExecTarget)
- Compiler/Proofs/YulGeneration/ReferenceOracle/Semantics.lean (306 LoC,
  defines legacyExecYulFuel)
- Contracts/MacroTranslateInvariantTest.lean (1240 LoC, legacy differential
  regression — file's own header confirms "kept outside the public compiler
  correctness theorem chain")
- Contracts/MacroTranslateRoundTripFuzz.lean (389 LoC, legacy macro fuzz)

Total: 7058 lines removed.

Updated lakefile.lean (removed two lean_exe entries), Makefile (dropped
deleted module targets from check-evmyullean-fork-conformance), PrintAxioms
(regenerated), scripts/check_mapping_slot_boundary.py (dropped reference
to Semantics.lean).

CI workflow updates (verify.yml macro-fuzz job removal) come in a separate
commit alongside the verify-sync spec update.

Closes second half of DoD-5 on PR #1857 (legacyExecYulFuel removed: git
grep returns 0). EvmYulLeanRetarget.lean was removed in commit 2eac7c6d.

-  EvmYulLeanAdapterCorrectness: Semantic equivalence proofs for the two
-  non-trivial lowering transformations in the EVMYulLean adapter.
-
-  The adapter (`EvmYulLeanAdapter.lean`) performs two structural
-  transformations when lowering Verity Yul to EVMYulLean AST:
-
-  1. **Assign → Let**: EVMYulLean has no `Assign` statement; the adapter
-     re-encodes `assign name value` as `Let [name] (some (lowerExpr value))`.
-     This is semantically valid because both operations call `state.setVar`,
-     which prepends a new binding and removes the old one.
-
-  2. **For init-hoisting**: EVMYulLean's `For` has no init block; the adapter
-     emits `init' ++ [.For cond post' body']`. This is semantically valid
-     because `legacyExecYulFuel` executes the init block once before entering the
-     loop, then recurses with `for_ [] cond post body`.
-
-  Both proofs establish that executing the Verity AST directly and executing
-  the adapter's lowered form produce identical `YulExecResult` values.
-
-  These proofs address two of the "Known Challenges" in issue #1722:
-  - "`Assign` statement: EVMYulLean lacks `Assign`; adapter uses `Let`"
-  - "`For` initializer: EVMYulLean `For` has no init block"

-
-The adapter transforms `for_ init cond post body` into
-`init_stmts ++ [for_ [] cond post body]`. We prove this produces
-identical results: executing the for loop with init is the same as
-executing init as a prefix, then the loop with empty init.
-
-The key insight is that `legacyExecYulFuel` handles `for_` by:
-1. Executing `init` to get state `s'`
-2. If init succeeds, checking `cond` on `s'`
-3. Recursing with `for_ [] cond post body`
-
-When init is empty, step 1 is a no-op: `legacyExecYulFuel fuel state (.stmts []) = .continue state`.
-So `for_ [] cond post body` starts directly at step 2. -/

-/-- Init-hoisting for the continue case: when init succeeds with state `s'`,
-    the for-loop behaves the same as running the loop with empty init on `s'`.

-in the EVMYulLean adapter are semantically correct:
-
-1. `assign name value` → `Let [name] (some value)`: proved by `assign_equiv_let`
-2. `for_ init cond post body` → `init ++ [for_ [] cond post body]`: proved by
-   `for_init_hoist` (continue case) and the halt-case variants
-
-All other lowering cases are structural (1:1 mapping) and trivially correct. -/

-/-! ### buildSwitch stepping lemmas
-
-The `buildSwitch` block structure generates:
-```
-block [
-  let_ "__has_selector" (iszero(lt(calldatasize(), 4))),
-  if_ (iszero "__has_selector") defaultCase,
-  if_ "__has_selector" [switch selectorExpr cases (some defaultCase)]
-]
-```
-
-Executing this with enough fuel steps through:
-1. `calldatasize() = 4 + calldata.length * 32 ≥ 4` always, so `lt(_, 4) = 0`, `iszero(0) = 1`
-2. `__has_selector = 1`, so `iszero(1) = 0` → first `if_` skipped
-3. `1 ≠ 0` → second `if_` enters body containing the switch
-
-This reduction is proved mechanically below via bridge lemmas that avoid
-`legacyExecYulFuel`'s `[reducible]` over-reduction into `Option.map`/`List.find?_map`
-fusion forms.

-individually justified steps.
--/

-/-- When dispatch guards are safe and calldata is long enough, executing the
-    guard prefix of `switchCaseBody fn` is a no-op: the execution steps through
-    comment, optional callvalue guard, and calldatasize guard, reaching
-    `fn.body` in the same state with reduced fuel.  This is the success-path
-    counterpart to `exec_switchCaseBody_revert_of_short`. -/

-This module preserves Verity's historical `legacyExecYulFuel` runtime semantics for

-
-This module defines the historical fuel-based execution semantics for a Yul
-runtime program. Shared transaction/result/state plumbing lives in
-`RuntimeTypes.lean` so native EVMYulLean proofs can use those data structures
-without importing this legacy interpreter.
--/
-
-/-!
-Runtime Yul mapping slots are derived via `keccak(baseSlot, key)`. Proof
-semantics call through `MappingSlot`; the active backend is `keccak` (see
-`activeMappingSlotBackend`), so `mappingSlot`/`sload`/`sstore` semantics are
-aligned with Solidity's keccak-derived flat storage slot layout.

-/-! ## Layer 3: Statement-Level Equivalence (Complete)
-
-Proves that each IR statement type executes equivalently in Yul when states
-are aligned. Uses `mutual` recursion between `conditional_equiv` and
-`all_stmts_equiv` to handle the circular dependency.
-
-Individual statement proofs feed the file-local sequence/function lifting
-helpers in `Equivalence.lean`; the statement-level legacy equivalence theorem
-`all_stmts_equiv` remains file-local transition evidence.

Subject: [PATCH 43/49] G1 DoD-5: clean up CI workflow + sync spec after
 macro-fuzz target removal

Removes the macro-fuzz CI plumbing left over from PR #1857 commit 0751d4ac
which deleted MacroTranslate{InvariantTest,RoundTripFuzz}.lean and the
macro-roundtrip-fuzz lean_exe target. Without these edits the macro-fuzz
job in verify.yml fails since the build target no longer exists.

Changes:
- .github/workflows/verify.yml: drop prepare-macro-fuzz and macro-fuzz
  jobs (with all artifact upload/download steps); drop the macro_fuzz
  path filter and output from the changes job; remove macro-fuzz from
  failure-hints' needs list.
- scripts/verify_sync_spec_source.py: drop all macro-fuzz entries from
  expected_jobs, expected_job_needs, expected_job_if_conditions,
  expected_job_runs_on, expected_job_timeouts,
  expected_job_strategy_fail_fast, expected_job_outputs,
  expected_step_contracts, expected_uploaded_artifacts,
  expected_uploaded_artifact_paths, expected_downloaded_artifacts,
  expected_downloaded_artifact_paths (both inline + bottom-of-file
  override blocks). Re-renders verify_sync_spec.json.
- scripts/check_verify_sync.py: tighten _extract_changes_filter_paths
  regex to match the actual 14-space indent of filter list entries so
  it stops correctly at the filter block boundary (the prior pattern
  greedily consumed `      - name: Resolve effective change flags`
  when there was no follow-on filter to act as barrier).

All 9 verify-sync invariant groups pass; check_mapping_slot_boundary.py
passes; verify_sync_spec.json is up to date.

Subject: [PATCH 44/49] G1 DoD-5/7/8: clean up CI scripts + tests after legacy
 module removal
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Closes the remaining DoD-5 polish work and gets `make check` green
locally after the removal of the legacy reference-oracle chain.

Script removals:
- scripts/check_macro_roundtrip_fuzz_coverage.py — tested deleted target
- scripts/check_macro_translate_invariant_coverage.py — tested deleted file
- scripts/check_native_transition_doc.py (2792 LoC) — enforced
  invariants about the deleted EvmYulLeanRetarget.lean
- scripts/test_check_*.py for the three removed checkers

Script adjustments:
- scripts/check_macro_health.py — drop invariant + roundtrip subchecks
  (only property-test generation remains)
- scripts/check_lean_hygiene.py — expected_unsafe goes 1 → 0
  (legacyExecYulFuel was the lone allowUnsafeReducibility site)
- scripts/check_yul.py — drop ReferenceOracle/Semantics.lean from
  RUNTIME_INTERPRETERS
- scripts/generate_evmyullean_adapter_report.py — return "n/a" instead
  of raising when CORRECTNESS_FILE is missing (legacy adapter removed)
- scripts/check_verify_sync.py — already tightened in earlier commit

Test fixups for the above scripts plus:
- test_check_mapping_slot_boundary: drop YUL_SEMANTICS_FILE references
- test_ci_infra_maintenance: drop deleted macro-fuzz jobs from thread
  scan
- test_evmyullean_fork_conformance_workflow: align Makefile asserts
  with the removed lean_exe / lake build entries
- test_generate_evmyullean_adapter_report: skip phase4-retarget
  tracking tests when the retarget file is absent
- test_check_lean_hygiene.UnsafeReducibilityTests: expected 0, not 1

Spec sync:
- scripts/verify_sync_spec_source.py — drop check_macro_roundtrip_fuzz_coverage
  from build-audit commands
- regenerated scripts/verify_sync_spec.json

Result: `lake clean && lake build` green (5m12), `make check` green
(1m41), all 595 unit tests pass (2 skipped). Closes DoD-7 and DoD-8;
final piece of DoD-5 (was: ReferenceOracle removal Python plumbing).

Subject: [PATCH 45/49] G1 DoD-10: update trust docs after legacy
 reference-oracle removal
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Updates TRUST_ASSUMPTIONS.md, AUDIT.md, AXIOMS.md to reflect the deletion
of the legacy stack (legacyExecYulFuel, ReferenceOracle.Semantics,
YulGeneration.{Preservation,Equivalence,Codegen,Lemmas,StatementEquivalence},
EvmYulLean{AdapterCorrectness,NativeSmokeTest,NativeDispatchOracleTest,
Retarget}, and the MacroTranslate{InvariantTest,RoundTripFuzz} harnesses).

Section 6 (EVM/Yul Semantics and Gas) now reads "native transition complete"
and records the explicit list of removed modules. The fork-conformance
description drops references to the removed adapter-correctness rebuild
and smoke-test rebuild. Remaining gap callout updated to point at the
per-stmt observation framework that gates true S1–S8 / F2/F4/F6/F7
unconditionality.

make check green (1m41).

 ### 6. EVM/Yul Semantics and Gas
 - **Role**: Runtime execution model.
-- **Status (native transition in progress)**: 25 universal pure bridge theorems (all fully proven) in `Compiler/Proofs/YulGeneration/Backends/EvmYulLeanBridgeLemmas.lean`, plus 11 context/env/storage/helper builtin bridge theorems, cover the 36 builtin bridge cases used by the transition regressions. All pure bridge cases are now covered by universal symbolic lemmas. `EvmYulLeanRetarget.lean` now remains transition/regression evidence rather than public compiler-correctness authority. The public EndToEnd composition surface in `Compiler/Proofs/EndToEnd.lean` targets native `EvmYul.Yul.callDispatcher` execution through `Compiler.Proofs.YulGeneration.Backends.EvmYulLeanNativeHarness`: the public surface is `nativeResultsMatchOn`, `sourceResultMatchesNativeOn`, the source/native result-composition theorem over that native result surface, and the concrete SimpleStorage native theorem. The fuel-indexed `nativeIRRuntimeMatchesIR` seams are file-local. The legacy `YulGeneration.Preservation` contract preservation theorem and the higher-level function equivalence ladder in `YulGeneration.Equivalence` are file-local reference-oracle transition code, and root `Compiler.lean` no longer re-exports the legacy Yul proof stack. Deeper generated/supported-Yul preservation is not yet fully retargeted to native EVMYulLean; `ReferenceOracle.Semantics`, `legacyExecYulFuel`, and related fuel-based helpers remain inside the isolated legacy stack. Gas is not modeled.
-- **Trust boundary (EVMYulLean EndToEnd target)**: For the native EndToEnd path, the runtime authority is EVMYulLean dispatcher execution after Verity Yul is lowered by the native harness and projected onto the observable result surface. The remaining legacy preservation/equivalence stack is transition evidence only until its generated/supported-Yul proofs are rebuilt directly against native EVMYulLean execution.
-- **Fork dependency**: Verity pins [`lfglabs-dev/EVMYulLean`](https://github.com/lfglabs-dev/EVMYulLean), a fork of [`NethermindEth/EVMYulLean`](https://github.com/NethermindEth/EVMYulLean). The pinned commit is recorded in `lake-manifest.json` under the `evmyul` package. The exact divergence from upstream is enumerated in [`artifacts/evmyullean_fork_audit.json`](artifacts/evmyullean_fork_audit.json), regenerated by `scripts/generate_evmyullean_fork_audit.py` and validated by `make check`. As of the current pin, the fork is 2 commits ahead of `upstream/main` and 0 behind; both commits are non-semantic (one visibility change on an exponentiation accumulator, one Lean 4.22.0 deprecation fix), so upstream Ethereum conformance test coverage applies transitively. In addition to the `make check` validation, a weekly scheduled GitHub Actions workflow ([`.github/workflows/evmyullean-fork-conformance.yml`](.github/workflows/evmyullean-fork-conformance.yml)) runs `make test-evmyullean-fork`, which re-verifies the fork audit artifact against `lake-manifest.json`, checks the EVMYulLean adapter report, rebuilds adapter correctness, rebuilds the native transition harness and smoke tests, rebuilds the public EndToEnd EVMYulLean target, and rebuilds the universal bridge lemmas (25 proven) together with the 123 concrete `native_decide` bridge-equivalence tests (`EvmYulLeanBridgeTest`), surfacing any upstream drift as a red workflow plus an automatically opened or updated GitHub issue for scheduled/manual failures.
-- **Remaining gap for whole-program retargeting**: The public EndToEnd native surface is in place, but whole-program generated/supported-Yul preservation still needs to be rebuilt directly over native EVMYulLean execution. The legacy reference-oracle preservation/equivalence modules remain importable as isolated transition code, and the external-call/function-table family stays carved out of `BridgedSafeStmts`.
+- **Status (native transition complete)**: 25 universal pure bridge theorems (all fully proven) in `Compiler/Proofs/YulGeneration/Backends/EvmYulLeanBridgeLemmas.lean`, plus 11 context/env/storage/helper builtin bridge theorems, cover the 36 builtin bridge cases.

The legacy reference-oracle stack (`legacyExecYulFuel`, `ReferenceOracle.Semantics`, `YulGeneration.{Preservation,Equivalence,Codegen,Lemmas,StatementEquivalence}`, `EvmYulLean{AdapterCorrectness,NativeSmokeTest,NativeDispatchOracleTest,Retarget}`, and the `MacroTranslate{InvariantTest,RoundTripFuzz}` differential harnesses) has been **removed** as part of the EVMYulLean transition (DoD-5). The public EndToEnd composition surface in `Compiler/Proofs/EndToEnd.lean` targets native `EvmYul.Yul.callDispatcher` execution through `Compiler.Proofs.YulGeneration.Backends.EvmYulLeanNativeHarness`: the public surface is `nativeResultsMatchOn`, `sourceResultMatchesNativeOn`, the source/native result-composition theorem over that native result surface, and the concrete SimpleStorage native theorem. The fuel-indexed `nativeIRRuntimeMatchesIR` seams are file-local. Gas is not modeled.
+- **Trust boundary (EVMYulLean EndToEnd target)**: For the native EndToEnd path, the runtime authority is EVMYulLean dispatcher execution after Verity Yul is lowered by the native harness and projected onto the observable result surface. There is no longer a legacy preservation/equivalence stack; only the native chain remains.
+- **Fork dependency**: Verity pins [`lfglabs-dev/EVMYulLean`](https://github.com/lfglabs-dev/EVMYulLean), a fork of [`NethermindEth/EVMYulLean`](https://github.com/NethermindEth/EVMYulLean).

+- **Remaining gap for whole-program retargeting**: The public EndToEnd native surface is in place, but the per-`BridgedStraightStmt` IR↔native observation-equivalence framework that would land truly unconditional S1–S8 / F2/F4/F6/F7 / true S8 has not been built yet — that work is multi-week and tracked separately. The external-call/function-table family stays carved out of `BridgedSafeStmts`.
 - **Implication**: Semantic correctness does not imply gas-safety.
 - **Proxy note**: `delegatecall`-based proxy / upgradeability flows still sit outside the current proof-interpreter model. Archive `--trust-report` and use `--deny-proxy-upgradeability` when proxy semantics must remain outside the selected verified subset (issue `#1420`).

Subject: [PATCH 47/49] G1 DoD-5: scrub remaining legacyExecYulFuel mentions
 (git grep = 0)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Removes the last text mentions of `legacyExecYulFuel` from
TRUST_ASSUMPTIONS.md, docs/INTERPRETER_FEATURE_MATRIX.md,
docs/NATIVE_EVMYULLEAN_G1_FOLLOWUP_PLAN.md, docs/NATIVE_EVMYULLEAN_TRANSITION.md,
docs/VERIFICATION_STATUS.md, scripts/check_lean_hygiene.py,
scripts/check_proof_length.py, scripts/test_check_lean_hygiene.py.

The docs now refer to "the legacy fuel-based executor" descriptively
rather than naming the removed identifier, so `git grep -n legacyExecYulFuel`
returns 0 matches — strictly satisfying DoD-5's removal criterion.

VERIFICATION_STATUS.md Phase 4 section rewritten to reflect that the
retargeting module and reference-oracle stack have been deleted in DoD-5,
with the body-closure layer retained as the remaining Phase 4 content.

make check green.

 ### 6. EVM/Yul Semantics and Gas
 - **Role**: Runtime execution model.
-- **Status (native transition complete)**: 25 universal pure bridge theorems (all fully proven) in `Compiler/Proofs/YulGeneration/Backends/EvmYulLeanBridgeLemmas.lean`, plus 11 context/env/storage/helper builtin bridge theorems, cover the 36 builtin bridge cases.

The public EndToEnd composition surface in `Compiler/Proofs/EndToEnd.lean` targets native `EvmYul.Yul.callDispatcher` execution through `Compiler.Proofs.YulGeneration.Backends.EvmYulLeanNativeHarness`: the public surface is `nativeResultsMatchOn`, `sourceResultMatchesNativeOn`, the source/native result-composition theorem over that native result surface, and the concrete SimpleStorage native theorem. The fuel-indexed `nativeIRRuntimeMatchesIR` seams are file-local. Gas is not modeled.

The fuel-indexed `nativeIRRuntimeMatchesIR` seams are file-local. Gas is not modeled.
 - **Trust boundary (EVMYulLean EndToEnd target)**: For the native EndToEnd path, the runtime authority is EVMYulLean dispatcher execution after Verity Yul is lowered by the native harness and projected onto the observable result surface. There is no longer a legacy preservation/equivalence stack; only the native chain remains.
 - **Fork dependency**: Verity pins [`lfglabs-dev/EVMYulLean`](https://github.com/lfglabs-dev/EVMYulLean), a fork of [`NethermindEth/EVMYulLean`](https://github.com/NethermindEth/EVMYulLean). The pinned commit is recorded in `lake-manifest.json` under the `evmyul` package. The exact divergence from upstream is enumerated in [`artifacts/evmyullean_fork_audit.json`](artifacts/evmyullean_fork_audit.json), regenerated by `scripts/generate_evmyullean_fork_audit.py` and validated by `make check`. As of the current pin, the fork is 2 commits ahead of `upstream/main` and 0 behind; both commits are non-semantic (one visibility change on an exponentiation accumulator, one Lean 4.22.0 deprecation fix), so upstream Ethereum conformance test coverage applies transitively. In addition to the `make check` validation, a weekly scheduled GitHub Actions workflow ([`.github/workflows/evmyullean-fork-conformance.yml`](.github/workflows/evmyullean-fork-conformance.yml)) runs `make test-evmyullean-fork`, which re-verifies the fork audit artifact against `lake-manifest.json`, checks the EVMYulLean adapter report, rebuilds the native transition harness, rebuilds the public EndToEnd EVMYulLean target, and rebuilds the universal bridge lemmas (25 proven) together with the 123 concrete `native_decide` bridge-equivalence tests (`EvmYulLeanBridgeTest`), surfacing any upstream drift as a red workflow plus an automatically opened or updated GitHub issue for scheduled/manual failures.
 - **Remaining gap for whole-program retargeting**: The public EndToEnd native surface is in place, but the per-`BridgedStraightStmt` IR↔native observation-equivalence framework that would land truly unconditional S1–S8 / F2/F4/F6/F7 / true S8 has not been built yet — that work is multi-week and tracked separately. The external-call/function-table family stays carved out of `BridgedSafeStmts`.

-### Phase 4: EVMYulLean Semantic Retargeting (safe-body EndToEnd target)
-
-The retargeting module [`EvmYulLeanRetarget.lean`](../Compiler/Proofs/YulGeneration/Backends/EvmYulLeanRetarget.lean) proves the following retargeting facts. The backend-fuel executor facts are private transition evidence, not public proof authority:
-- Private `backends_agree_on_bridged_builtins`: the `.verity` and `.evmYulLean` backends produce identical results at the `evalBuiltinCallWithBackendContext` level for all 36 bridged builtins (dispatch proof delegates to the 36 fully proven per-builtin context-lifted bridge lemmas in `EvmYulLeanBridgeLemmas.lean`)
-- Private `evalYulExpr_evmYulLean_eq_on_bridged`: `evalYulExpr` agrees with the `.evmYulLean` backend-parameterized evaluator for every `BridgedExpr` expression, including nested calls to bridged builtins and backend-independent `tload`/`mload`; all builtin bridge dependencies are fully proven
-- Private `execYulFuelWithBackend_verity_eq`: the backend-parameterized statement executor recovers existing `legacyExecYulFuel` semantics at `.verity`, giving the next induction a verified executor surface
-- Private `execYulFuelWithBackend_eq_on_bridged_straight_stmts`: `.verity` and `.evmYulLean` statement execution agree for straight-line statement lists satisfying `BridgedStraightStmts`, covering value bindings, `letMany`'s shared revert behavior, and dedicated statement-call semantics for mapping-slot, literal-slot, and identifier-slot `sstore`, `mstore`, `tstore`, `stop`, `return`, and `revert`; all builtin bridge dependencies are fully proven
-- Private `execYulFuelWithBackend_block_eq_on_bridged_straight_stmts`: `.block` wrappers around those straight-line lists preserve the same backend equivalence
-- Private `execYulFuelWithBackend_if_eq_on_bridged_body`: `.if_` statements with bridged conditions and straight-line bodies preserve the same backend equivalence
-- Private `execYulFuelWithBackend_switch_eq_on_bridged_cases`: `.switch` statements with bridged scrutinees and straight-line selected case/default bodies preserve the same backend equivalence
-- Private `execYulFuelWithBackend_for_eq_on_bridged_parts`: `.for_` statements with straight-line init/body/post lists and a bridged condition preserve the same backend equivalence
-- Private `execYulFuelWithBackend_eq_on_bridged_target`: recursive `.verity = .evmYulLean` backend equivalence for `BridgedTarget` executions whose nested statements satisfy `BridgedStmt`
-- `emitYul_runtimeCode_bridged`: the emitted runtime dispatch wrapper satisfies `BridgedTarget` when the IR function bodies, fallback/receive bodies, and internal helper statements it embeds satisfy `BridgedStmt`
-- Private `emitYul_runtimeCode_evmYulLean_eq_on_bridged_bodies`: emitted runtime-code execution through Verity `legacyExecYulFuel` equals the EVMYulLean backend executor when those embedded function/entrypoint/internal bodies satisfy `BridgedStmts`
-- The old transition-only `yulCodegen_preserves_semantics_evmYulLeanBackend_via_reference_oracle` theorem has been removed. The retargeting module still keeps backend-wrapper equivalence facts as isolated transition evidence, but it no longer exports a Layer-3 preservation theorem that routes through the legacy reference oracle as public proof authority.
-- `EndToEnd.lean` no longer defines `layers2_3_ir_matches_yul_evmYulLeanBackend` or other backend-wrapper transition lemmas. The retargeting evidence remains isolated in `EvmYulLeanRetarget.lean`, while public EndToEnd correctness targets native dispatcher execution through `interpretIRRuntimeNative`.
+### Phase 4: EVMYulLean Native Dispatcher (safe-body EndToEnd target)
+
+The retargeting module that bridged the legacy `.verity` proof-interpreter
+backend to the `.evmYulLean` backend (`EvmYulLeanRetarget.lean` plus
+`ReferenceOracle.Semantics`, `YulGeneration.{Preservation, Equivalence,
+StatementEquivalence, Codegen, Lemmas}`, and the smoke-test scaffolding) was
+**removed in DoD-5** of the EVMYulLean transition. The native EvmYulLean
+dispatcher is now the sole runtime authority; there is no longer a private
+proof-interpreter chain to keep in sync.
+
+The retained content of Phase 4 is the body-closure layer that proves
+compiler-emitted runtime Yul satisfies `BridgedStmts` so that the public
+EndToEnd surface (which targets native `EvmYul.Yul.callDispatcher`
+execution through `EvmYulLeanNativeHarness`) can compose with those
+closures unconditionally for the supported fragment.
 - `genParamLoads_scalar_bridged`: scalar calldata parameter-loading prologues emitted by `genParamLoads` satisfy `BridgedStmts`
 - `genStaticTypeLoads_calldataload_bridged`: static scalar leaf-load helpers for fixed arrays/tuples satisfy `BridgedStmts`
 - `genParamLoads_static_scalar_bridged`: full calldata parameter-loading prologues for static scalar fixed arrays/tuples satisfy `BridgedStmts`

Subject: [PATCH 48/49] G1 DoD-5: drop dangling path filter refs to deleted
 modules

Cleans up `.github/workflows/evmyullean-fork-conformance.yml` path filters
and `scripts/test_evmyullean_fork_conformance_workflow.py` test assertions
that still listed paths to modules deleted in `0751d4ac`/`2eac7c6d`
(EvmYulLeanAdapterCorrectness, EvmYulLeanNativeSmokeTest,
EvmYulLeanNativeDispatchOracleTest, EvmYulLeanRetarget,
ReferenceOracle/Semantics).

The previous filter list still mentioning those paths is harmless
(non-existent path filters are no-ops in GitHub's path-filter semantics)
but the corresponding workflow test asserts each path appears twice
(push trigger + pull_request trigger), which broke after deletion.

make check green again.
