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. Co-Authored-By: Claude Opus 4.7 <noreply@anthropic.com>
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.
…eave name slot Claims the planned name slot for S5 with the exact signature from the stage-2 DAG, narrowed by a temporary `hOnlyEmpty : preStmts = []` hypothesis so it reduces to `of_leave_body` via `[] ++ [.leave] = [.leave]`. Future strengthening removes `hOnlyEmpty` and inducts over `NativePreservableStraightStmts preStmts` via the per-stmt `NativeStmtPreservesWord_revived` framework (P1 in the stage-2 DAG). Also regenerates PrintAxioms.lean to include the new S5 + S6 (from `7b9c2e86`) constructor entries; total 5293 lemmas (3564 public, 1729 private, 0 sorry'd). No new axioms; sorry count unchanged.
…ough SuccessBridge chain Claims two more planned name slots for the E7 S7 component with exact signatures from the stage-2 DAG, narrowed by `hOnlyEmpty : preStmts = []`: - NativeGeneratedSelectorHitUserBodyPreservesBridgeAtFuel.of_bridgedStraightStmts_falling_through - NativeGeneratedSelectorHitSuccessBridge.of_bridgedStraightStmts_falling_through Both reduce to the existing `of_empty_body` chain. Future strengthening removes `hOnlyEmpty` and inducts over `BridgedStraightStmts preStmts` via the per-stmt observation framework (P1 in the stage-2 DAG). PrintAxioms: total 5295 lemmas (3564 public, 1731 private, 0 sorry'd). No new axioms; sorry count unchanged.
…y constructor 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).
…proof) 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`). PrintAxioms: 5296 → 5297 (+1 private theorem). No new axioms; sorry count unchanged.
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).
…mts_leave 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). PrintAxioms: 5301 → 5302 (+1). No new axioms; sorry count unchanged.
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.
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.
…f_block_leave) 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.
…eAwareCallDispatcherContinuation)
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).
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).

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).
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).
…ough_with_label_prefix) 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. PrintAxioms: 5310 → 5311 (+1 private theorem). No new axioms; sorry count unchanged (7 pre-existing).
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 (eb9b973), 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. PrintAxioms: 5311 → 5314 (+3 private theorems). Lake build green; make check green; sorry/axiom counts unchanged.
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.
…er_ok 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). Lake build green; sorry/axiom counts unchanged.
`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.
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.
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. PrintAxioms: 5320 → 5321 (+1 public theorem). Lake build green; sorry/axiom counts unchanged.
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. PrintAxioms: 5321 → 5323 (+2 private theorems). Lake build green; sorry/axiom counts unchanged.
…hesis) 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.
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.

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_*`.

…iveJump 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 b89b43c.

paramDynamicMember{Length,DataOffset,Element}) shipped in upstream PRs
#1858-#1862, plus the dispatchBody / DynamicData helpers they reference.
Followup to the merge commit `60d38ba8`.
…of_user_body 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. PrintAxioms regenerated.
…le_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. PrintAxioms regenerated.
…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 b002443 + b5410c1 follow the exact same shape (cons + block + if + revert + user). Extend the regex to cover both forms.
…ork) 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 (60d38ba) absorbing new IR Expr constructors Tracks state without changing any proofs.
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. PrintAxioms regenerated.
Ships `eval_callvalue_preserves_reviveJump_of_ok_at_fuel` — parallel to the lt-calldatasize Ok-input discharge from c6f24ef. 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.

Summary
Stacked follow-up to merged #1826 (which shipped the Path B `_revived` foundation + upstream Expr cascade fix). This PR carries the remaining G1 S5-S8 work:
Approach
D1/D2 require a per-`BridgedStraightStmt`-constructor IR↔native observation-equivalence theorem that does not yet exist as generic infrastructure (each existing concrete-body helper hand-rolls its own equivalence inline). Stage 2's first task is to build that compositional theorem, then D2 (simpler — falling-through), then D1 (preStmts ++ [.leave]), then the E/F/G chains.
See `docs/NATIVE_EVMYULLEAN_G1_FOLLOWUP_PLAN.md` Stage 2 section for detailed sequencing.
Status
Currently scaffolding — only the Stage 2 plan section is committed. Implementation work to follow across multiple commits.
