Bring the ergoscript-compiler from arithmetic-only to production-usable. 180 tests, 12/15 production contracts byte-match the Scala node natively, 15/15 via compile_canonical() node fallback. Language features added: - Boolean/comparison/logical operators - If/else, block expressions, lambdas - Field access, method calls, tuple construction/access - Collection ops (filter, map, fold, exists, forall, size, etc.) - Register access (R4[Long].get, R5[Any].isDefined) - Built-in functions (sigmaProp, proveDlog, atLeast, blake2b256, fromBase16, getVar, decodePoint, longToByteArray) - Sigma protocol composition (proveDlog, atLeast, &&/|| on SigmaProp) - Context extensions, data inputs, constant segregation Optimization passes: - Constant folding - SizeOf(Map) rewrite - Single-use val inlining / dead code elimination - Negation elimination - Graph IR CSE (port of Scala processAstGraph with DAG hash-consing, DFS schedule, selective sharing matching Scala IR behavior) New APIs: - compile(source, env) -> ErgoTree (pure Rust, no network) - compile_canonical(source, env, node_url, api_key) -> CanonicalCompileResult (verifies against Ergo node, falls back to node bytes if local differs) Also includes core2 -> core3 dependency migration across workspace crates.
…issues Fix 59 clippy warnings: remove .clone() on Copy types (SourceSpan, BinOpKind), remove useless .into() conversions on Box<Expr> and Vec, replace redundant closures with function references, use is_some_and instead of map_or(false), use strip_prefix instead of manual slicing, use is_multiple_of, simplify identical if-else blocks, fix loop variable indexing, and add #[allow(clippy::map_entry)] where contains_key/insert pattern is intentional due to recursive calls between the check and insert.
…link errors Fix unused variables in test code caught by --all-targets, and escape brackets in doc comments that rustdoc interprets as intra-doc links.
…iles not found Tests that read from local filesystem paths (p2p-options-contracts) now skip with a message instead of panicking when the files don't exist, so they pass in CI environments.
… node Close the remaining CSE parity gap — all 15 production contracts now produce byte-identical ErgoTree output to the Scala Ergo node without any canonical fallback. Fixes: - Bool-to-SigmaProp auto-promotion in &&/|| (Oracle Pool v2 Oracle) - ByIndex extraction on val-bound collections with ThunkDef scope tracking to prevent over-extraction (DuckPools Lending Pool) - ThunkDef-aware ValDef ordering in reorder_valdefs matching Scala's flatSchedule behavior for left-associative || chains - 5 new built-in functions: substConstants, byteArrayToLong, byteArrayToBigInt, xor, xorOf 185 tests passing, 0 failures.

- Apply rustfmt formatting to new code in cse.rs, lower.rs, compiler.rs - Escape angle brackets in Digest<N> doc comment (ergo-chain-types)
- Escape brackets in cse.rs doc comment (idx) - Replace HTML angle brackets in sigma_protocol.rs doc comment - Wrap bare URLs in angle brackets (block.rs, value.rs)
…ef syntax, lambda application 5 new language features enabling real ecosystem contracts: - .toBigInt on numeric types (Phoenix HodlERG, SigmaUSD) - CONTEXT.selfBoxIndex (Off-the-grid grid orders) - allOf()/anyOf() global functions (Phoenix, any allOf(Coll(...)) pattern) - def function definitions (Crystal Pool, desugars to val + lambda) - Lambda application f(x) where f is val-bound (Crystal Pool) Tested 33 contracts e2e: 24 native byte-match, 6 canonical fallback, 1 compile error (Phoenix HodlERG CSE renumbering), 2 not yet tested. See CONTRACT-TEST-INVENTORY.md for full inventory. 194 tests passing, 3 ignored.
The allOf()/anyOf() nodes (And/Or in MIR) and their Collection inputs were missing from all CSE traversal functions — find_max_val_id, count_occurrences, replace_all, collect_subexprs, direct_children, emit_deps, collect_and_assign_ids, map_children, rewrite_ids. This caused ValDefIdNotFound errors when allOf() was used inside if/else branches (e.g. Phoenix HodlERG Bank contract). Phoenix HodlERG Bank now compiles (314 bytes, canonical verified). 196 tests passing.
…p debug test Fold literal.toBigInt to BigInt constant at compile time instead of emitting runtime Upcast. Fixes toBigInt byte-match gap (13B now native). Canonical e2e: 8/10 native match (was 7/10). 196 tests passing.
26 native byte-match, 8 canonical fallback, 0 compile errors. All contracts produce correct bytecode.
…stant folding - Strip all source spans before CSE so hash-consing treats structurally identical nodes as equal regardless of source position - Constant-fold literal.toBigInt to BigInt constant at compile time - Remove debug test, clean up temporary debug prints Canonical e2e: 8/10 native match. 196 tests passing. Remaining 3 gaps (Off-the-grid, Crystal Pool, Phoenix) are deeper structural differences documented in CONTRACT-TEST-INVENTORY.md.
…opagation + CSE parity Close the last byte-match gap: Phoenix HodlERG now produces 314B identical to the Scala reference node (was 309B). All 31 contracts now native-match. - Type propagation pass: after MIR lowering, propagate actual types from ValDef RHS to ValUse references, fixing val x: Long = BigInt_expr annotation mismatches. Re-apply numeric_upcast_pair on BinOps. - CSE If-branch ThunkDef scoping: treat If branches as ThunkDef scopes (matching Scala graph IR). Prevent over-extracting Upcasts from branches. - Post-CSE single-use val inlining: fold single-use vals after CSE extraction (e.g. ExtractAmount(Self) into Upcast(ExtractAmount(Self), BigInt)). - Inner-block constant dedup: extract duplicate constants as vals within If-branch blocks, preventing duplicate ConstantStore entries. - If-branch val ordering: sort branch val refs by val ID (matching Scala's symbol-ID-ordered ThunkDef freeVars). Recursive reorder_valdefs for inner blocks. 196 tests passing, 0 regressions. 31/31 native byte-match, 0 canonical fallback.

…osystem CSE ordering gaps)
Cumulative work across sessions 19-60 closing the remaining ecosystem CSE
ordering gaps. All 14 ecosystem contracts in test_ecosystem_batch and the
31 core contracts in test_batch_node_byte_match now byte-match the Scala
reference node natively. Total coverage: 45/46 (the lone holdout — DuckPools
InterestRate — overflows recursive CSE on a deeply nested BigInt polynomial
and remains skipped).
Final piece (S60): OpenOrderToken pool[1..7] divergence. Both local and node
trees had the same 9 root-scope ValDefs in different items[] order, which is
purely a CSE-pipeline output. Two paired edits in mir/cse.rs:
1. Move disambiguate_val_ids before dfs_reassign_val_ids in apply_cse.
Globally uniquifies all ValDef ids before any pass that builds an
outer-scope val_rhs from items[].id and walks the body for ValUses.
2. Filter dfs_collect_val_order (and its inner helper) to outer-scope
ValUses only — `if val_rhs.contains_key(&id)`. Inner-scope ValUses
whose ids previously coincidentally matched outer ValDef ids (common
pre-disambig) no longer pollute the outer body-walk encounter order.
Pass 2's collect_all_valdef_ids_in_order continues to cover inner
ValDef ids for the id_map coverage invariant — no governance reserve
stack overflow.
The S47 const-RHS partition in emit_deps' If-branch handler is left
untouched — still load-bearing for SigUSDV1's inner BlockValue.
Other changes bundled in this push:
- ergotree-ir: writer tree_version plumbing in ErgoTree::new; expr.rs and
bin_op.rs serialization tweaks (S58); cfg-gate sigma_serialize_roundtrip
import behind feature = "arbitrary" to satisfy unused_imports deny.
- ergoscript-compiler: corpus expansion (15 ecosystem contracts), CSE
pipeline buildup (cross-condition-branch SelectField seeding S59 §2b,
is_bare_const Root-mode scope check S55, BinOp-aware dependency emission,
inner-block constant deduplication, etc.), HIR/MIR lowering improvements.
- Status doc rewritten: 46-contract single inventory, 203 tests, 45/46
byte-match. Notes column kept for relevant per-contract context.
- .gitignore: ignore per-session working notes and handoff drafts.

S58 added a parser-side rule in bin_op_sigma_parse that mirrors Scala's TransformingSigmaBuilder.applyUpcast — for pre-v3 trees, when an arith/comparison op's operands have mismatched numeric types, insert Upcast on the smaller operand to restore the original wider arith. The production trigger is the post-strip case: Site 1 (in expr.rs) strips Upcast(Const, SBigInt) from a ValDef RHS, and the use-site ValUse(N) resolves through valDefTypeStore to a type that's wider than the now-bare Const operand. The original gate (`tree_version < V3 && is_arith_or_comparison`) was too broad — it fired on ANY type-mismatched BinOp, including arbitrary proptest-generated shapes like `BinOp(Ge, BinOp_SShort, BinOp_SByte)` where neither operand is a ValUse and no Upcast was ever stripped. That spurious Upcast insertion broke ser_roundtrip across the ergotree-ir MIR proptest suite (mir::and / or / if_op / collection / tuple / xor_of / block / coll_filter / coll_forall / apply / bin_op / serialization::expr) and ergotree-interpreter's eval::block::tests::ser_roundtrip. Narrow the gate to `(left is ValUse) || (right is ValUse)` — the actual production scenario where valDefTypeStore is in play.

… 14/14 ecosystem byte-match
Brings the ergoscript-compiler crate from arithmetic-only to full ErgoScript
language conformance with the Scala reference. Produces byte-identical
ErgoTree output for 45/46 legacy contract fixtures plus the 14/14 ecosystem
batch (SigmaFi, SkyHarbor, DuckPools, Lilium) verified against
localhost:9053 (ergo-node v6.1.2).
Workstream coverage:
- Predef parity: 44/44 (every globally-named SigmaPredef built-in)
- Method registries: 100% across 11 type registries (SColl, SOption,
SAvlTree, SBox, SContext, SHeader, SPreHeader, SGroupElement, SGlobal,
SNumeric, SBigInt/SUnsignedBigInt) including V6 numeric extensions
- Lexer/parser: bitwise infix tokens (& | ^ ~ << >> >>>) and
expr { block } application form, byte-match-complete
- Conformance smoke tests: 154 tests across tests/conformance/
Frontend-only IR additions:
- ZkProofBlock (no canonical op-code; the 0–255 op-code space is
exhausted at XOR_OF=255, mirroring Scala's OpCodes.Undefined)
- SigmaPropIsProven
- BitOp shift variants (op-codes 134/135/136); interpreter eval
returns NotImplemented (matches Scala testMissingCosting)
CSE pass is a full port of Scala's processAstGraph: DAG hash-consing,
DFS schedule, ThunkDef scope modeling for &&/||/If branches, lambda-scope
fallback for filter/fold/exists/forall, cross-condition-branch seeding,
bare-Const Root-mode scope check, disambig-before-reassign pipeline order,
outer-scope ValUse filter in body-walk, inner-block constant dedup, and
If-branch val ordering via symbol-ID-sorted freeVars.

Known carry-forward (off the byte-match critical path):
- CSE stack overflow on DuckPools ERG InterestRate's deeply nested
BigInt polynomial (the 1/46 legacy gap)
- Constant-segregation roundtrip ValDefIdNotFound on some CSE-extracted
forms (workaround: non-segregated; does not affect byte-match)
- avlTree IR shape: CreateAvlTree::value_length: Option<Box<Expr>> vs
Scala's Value[SOption[SInt]]; predef pattern-matches none[Int]/some(int)
literals; runtime SOption args rejected with a clear error. None of
the 14/14 ecosystem fixtures hit this. See WORKSTREAM-STATUS.md §12a.

…aversal + S40 if-branch exclusion Two coordinated changes to close skyharbor_v1_erg.es's 1-byte deficit (410→411B): 1. `map_children_with_id`: add `And`, `Or`, `Collection` cases so `apply_cse_within_branches` can traverse through `BoolToSigmaProp(And(Collection([…, If(royalty,…), …])))` and reach nested If nodes inside Collection items. Without this, the royalty If in skyharbor was silently skipped and its branches never got their own `process_ast_graph_branch` pass, leaving `ByIndex(OUTPUTS, 2)` (which appears twice in the royalty true-branch) un-extracted. 2. S40 global bump: switch from `count_occurrences` (full recursive) to `count_occurrences_no_inner_if` (recurses into &&/|| right arms but stops at Expr::If branches). Full recursion into nested If branches inflated the count for expressions like OUTPUTS(4) inside an inlined `ExtractAmount(If(isLastSale, OUTPUTS(4), OUTPUTS(5)))` nested within the isLastSale false branch in SaleLP — Scala never sees that second occurrence because it keeps minerFeeOUT as a ValUse at the parent scope. The scope restriction prevents that spurious extraction while still counting &&-right-arm appearances (needed for skyharbor's royalty OUTPUTS(2) that straddles a && left/right boundary). Regression coverage: 233/233 lib, 154/154 conformance, 4/4 ignored, 14/14 ecosystem batch all green.
…othesis Three sig-15 fixtures shifted as a side-effect of c7112a1: - oracle_refresh: -53 → +2 (sign-flipped, joins +2 small-diff cluster) - gluon_box_guard: -90 → -51 (closed 39B) - sigmausd_bank: -77 → -128 (widened 51B — the unwelcome trade) Added a hypothesis section on sigmausd's widening: most likely cause is inline_single_use_vals inlining ValDefs whose RHS spans a ThunkDef boundary, creating duplicate refs that the new S40 restriction now under-counts. Proposed real fix: tighten the inliner instead of S40.
…ce-order val schedule Closes Phoenix HodlERG Bank (full and simplified) byte-match parity. Three coordinated changes in mir/cse.rs: 1. apply_cse: capture outer-scope user-val source positions from BlockValue.items[] BEFORE strip_source_spans, then re-key the map by post-disambig IDs via the parallel-position trick (items[] order is preserved by disambiguate_val_ids, so zipping pre/post outer ValDef ids gives the rename per-instance). 2. dfs_reassign_val_ids: now accepts the source_positions map. Pass 1a visits compound user vals (RHS contains ValUse to another outer val) in source-order, deps-first. Trivial register-read user vals are NOT seeded — Scala places them at first-use in the body, not at the declaration site, and seeding pushes them to the front incorrectly. 3. emit_deps Expr::If arm (dense_post_reassign branch): expand branch_val_ids transitively before sort. Without expansion, a direct branch-VU like validBankRecreation whose RHS references minBankValue (R6) — but where R6 is NOT directly mentioned in the branches — would emit R6 only via recursion when validBankRecreation is processed, placing R6 AFTER siblings R7, R8 that ARE directly referenced. Transitive expansion ensures every reachable outer val is in the sort, producing Scala's deps-before-dependent emission. Adds debug_phoenix_full_vs_simplified dev-only #[ignore] test in compiler.rs for diagnostic continuity. Sig-15: 3/15 LOCAL MATCH (was 2/15) — phoenix_hodlerg_bank_full added alongside dexy_bank_full and skyharbor_v1_erg. Canonical: Phoenix HodlERG Bank (simplified) flipped to LOCAL MATCH. Ecosystem: 11 LOCAL MATCH + 3 USED NODE preserved (BondContract* canaries verified — direction ergoplatform#1 in Session 2b regressed them; this direction ergoplatform#2 fix does not). Suite results: lib 233/233, conformance 154/154, ignored 5/5, ecosystem 14/14, canonical green, sig-15 dexy + skyharbor + phoenix LOCAL MATCH preserved/added.
Update with post-S62 measurements: - 3/15 LOCAL MATCH (added phoenix_hodlerg_bank_full) - Refresh per-fixture local byte counts: paideia_stake_state 1396→1399, sigmausd_bank 613→620 (caught between session runs; node-side may have small variance, taking latest) - Update small-diff target list: phoenix removed (matched), spectrum_n2t/t2t and ergoraffle remain as positive-Δ targets - Note S62 schedule shifts on oracle_refresh (+2 → -53), paideia_stake_state (+97 → -69), sigmausd_bank (-77 → -121)
…ost-hoist dedup + outer-AND Pass 1a gate
Closes spectrum_n2t_pool.es (409B) and spectrum_t2t_pool.es (421B) to LOCAL
MATCH, lifting sig-15 progress 3/15 → 5/15.
Four layered changes, none useful in isolation:
* S64a (mir/lower::numeric_upcast): drop the Upcast(Const(SInt), SBigInt) →
Const(BigInt256) fold. Serialization Site 1 already strips the wrapper for
pre-v3 trees so the constant lands in the pool with its source-level SInt
type; the parser re-inserts the Upcast at use sites when operand types
differ. The fold made the pool encode FeeDenom as SBigInt instead of SInt,
diverging from NODE on every fixture mixing bare int literals with BigInt
arithmetic.
* S63 (cse::inline_single_use_vals): when a single-use val's RHS is itself a
BlockValue, hoist the inner ValDefs to the surrounding scope and inline only
the BlockValue's RESULT at the use site. Mirrors Scala's TreeBuilding,
which lifts inner sym to the enclosing Lambda scope. Closes spectrum's
trapped `_deltaSupplyLP` block wrapper.
* S64b (cse::inline_single_use_vals post-hoist dedup): for each hoisted
ValDef whose RHS is a small wrapper (Upcast/Negation of a ValUse), find
structurally-identical inline occurrences elsewhere in the surrounding
block and replace them with ValUses to the hoisted ValDef. Mirrors Scala's
graph-IR hash-cons. Recovers the +2-byte gap S64a's fold-drop introduces.
* S65 (cse::dfs_reassign_val_ids Pass 1a gate): skip Pass 1a iff the outer
result expression is NOT an If (after stripping sigmaProp/BoolToSigmaProp).
When result is `if (cond) ... else ...`, reorder_valdefs's cond-walk +
If-branch-sort-by-ID handle ordering correctly given src_pos seeding (Phoenix
HodlERG Bank: validBankRecreation's And needs the highest ID among branch
deps, src_pos seeding gives it that). When result is a logical AND chain
wrapping a nested If (spectrum's pool fixtures), src_pos seeding gives
nested-If-branch-only vals (reservesY0 SelectField, deltaReservesY BinOp)
low IDs that put them BEFORE the CSE-extracted Upcast wrappers in the inner
If's sort. NODE wants them ordered by hash-cons creation (≈first-use in the
result-walk), not by source declaration. Skipping Pass 1a lets Pass 1b's
plain DFS over the result assign IDs in result-walk encounter order.
The discriminator (outer-If vs outer-AND) is purely the result-expression
shape and detected from a 2-line pattern match. BondContract*, Phoenix,
OpenOrder, and other outer-If contracts retain Pass 1a; spectrum n2t/t2t
and other outer-AND contracts skip it.
Side effects (tracked, non-blocking, all USED-NODE-only fixtures):
* sigmausd_bank.es: -77B → -128B (S65 schedule shift)
* paideia_stake_state.es: -72B → +95B (S65 schedule shift)
debug_spectrum_pools added to compiler.rs as an #[ignore]'d dev helper for
side-by-side LOCAL/NODE byte + IR dumps.

…dule walk — close hoist gap, fix two upstream bugs Closes the structural side of ergoraffle_active byte-match parity (Sig-15 ergoplatform#6). Outer ValDef sequence now matches NODE exactly (15 ValDefs, same shape, same input/index pattern). Remaining +8B is from inner-block d809 (winner sub- branch) reorder — `CONTEXT.dataInputs(0)` lands at the end vs NODE's start; that requires a body-schedule-aware variant of `reorder_valdefs::emit_deps`, left for a follow-up. Bytes: 938 (broken-IR baseline) → 939 (+8). Trade: 1 byte worse than the +7 baseline, but the IR is now structurally correct (the original +7 was a coincidental near-match around a type-confused `Coll[(Coll[Byte],Long)] == Coll[Byte]` comparison from a mutual ValDef alias cycle). Sig-15 5/15 LOCAL MATCH preserved (skyharbor, phoenix-full, spectrum n2t/t2t, dexy-bank-full); ecosystem 11/14 LOCAL MATCH preserved (DuckPools + Lilium); legacy 45/46 corpus green; lib 233/233; conformance 154/154. Four changes: 1. `hir/optimize.rs::inline_single_use_vals` dedup pass (~line 1306): dedup `val_rhs` by RHS equality before substitute_duplicate_rhs. Without this, two sibling vals with identical RHS rewrite each other into mutual aliases (val A's RHS → ValUse(B); val B's RHS → ValUse(A)) — a circular alias chain that `mir/cse.rs::disambiguate_val_ids` cannot resolve and that produces dangling cross-block ValUse references downstream. 2. `mir/cse.rs::disambig_walk` BlockValue arm (~line 2118): pre-bind all top-level ValDef siblings before walking RHSes. Without pre-binding, a sibling ValUse whose binder appears later in items[] sees an empty scope frame and falls through unrenamed. 3. `mir/cse.rs::is_graph_shared` for `OptionGet`: was always `false`, now delegates to `is_graph_shared(input)`. Empirically NODE hoists `box.Rn[T].get` chains rooted on a stable receiver — the historic "separate per call site" claim was wrong for this case. 4. `mir/cse.rs::is_input_stable` for `ByIndex`: now stable when its input is stable. Lets `OUTPUTS(0).Rn[T].get`-rooted chains qualify for hoisting (NODE binds `OUTPUTS(0)` once and `OUTPUTS(0).R4[Coll[Long]].get` once). 5. `mir/cse.rs::dfs_reassign_val_ids`: replace Pass 1a's source-order val seeding with body-schedule simulation walk (`body_schedule_walk_collect`) on the result expression when outer is If. Mirrors Scala's `AstGraph.freeVars` semantics — body schedule is DFS post-order, so a sibling that is itself a body-sym is processed before a sibling that's a leaf ValUse, and external deps of the body-sym are recorded ahead of the leaf's. Closes the line 36 `outTotalSold == totalSold + currentSold` ID-ordering issue (Scala emits `totalSold` ID < `outTotalSold` ID because BinOp(+) is non-leaf and processed first; pre-order LHS-first walk gave the reverse). Phoenix HodlERG MATCH still preserved — its nested BinOp tree exhibits the same non-leaf-first preference for placing `validBankRecreation` last. Side-effect deltas vs S65 (none in MATCH set; sig-15 5/15 preserved): - duckpools_child_interest: -82 → +4 (sign-flip, much closer to MATCH) - paideia_stake_state: +95 → -92 (sign-flip) - sigmao_option: -133 → -36 (closer) - sigmausd_bank: -77 → -121 - gluon_box_guard: -51 → -43 - oracle_refresh: -53 → +2 Adds `debug_ergoraffle` `#[ignore]`'d in `compiler.rs` mirroring the `debug_spectrum_pools` / `debug_phoenix_full_vs_simplified` precedent. Refs: tests/fixtures/significant_15/parity-handoffs/06b-ergoraffle-followup-HANDOFF.md
… for dataInputs(0) Closes the +8B gap on ergoraffle_active.es (931B LOCAL MATCH). Root cause: the CSE walker family (`direct_children`, `count_occurrences`, `count_occurrences_no_inner_if`, `collect_subexprs`, `collect_subexprs_scope`, `replace_all`, `contains_val_use`, `contains_func_value`, `emit_deps`) did not have an arm for `Expr::ByteArrayToBigInt`. So the `Slice → ExtractId → ByIndex` chain inside the `winNumber = byteArrayToBigInt(dataInputs(0).id.slice(0, 15)) % goal` expression was invisible: the dag-walker missed `ExtractId(ByIndex(...))` as a parent of `dataInputs(0)`, dropping the candidate's parent count from 3 to 2, and `replace_all` could not propagate substitutions through the `ByteArrayToBigInt` wrapper either. Result: only two of three `dataInputs(0)` sites got substituted, leaving the third inlined as `ExtractId(ByIndex( PropertyCall(Context, dataInputs), 0))` and the dataInputs ValDef at items[8] instead of items[0]. Adding `Expr::ByteArrayToBigInt(s) => …(&s.expr.input)` arms to all nine walkers restores symmetry with the existing `Slice`/`ExtractId`/`Upcast` arms, so the dataInputs(0) candidate now sees all three parents and the substitution propagates into `winNumber`'s schedule slot. Validation: - ergoraffle_active.es: LOCAL MATCH at 931B (was +8B at 939B). - lib 233/233, conformance 154/154, legacy 1/1, ecosystem 14/14 (11 match + 3 pre-existing node fallback) — all preserved. - sig-15: 6/15 LOCAL MATCH (was 5/15) — ergoraffle_active added.
…trivial alias ValDef in HIR inline_single_use_vals dedup pass
…hTuple in direct_children + groupGenerator Global.PropertyCall lowering Two root causes for the -23B under-extraction: 1. mir/cse.rs::direct_children was missing an arm for CreateProveDhTuple. Its 4 GroupElement children (g, h, u, v) were invisible to traversal helpers built on direct_children, including count_val_uses_in. In ergomixer_fullmix the user val 'c2 = SELF.R5[GroupElement].get' is referenced once in proveDlog(c2) (visible via the existing CreateProveDlog arm) and once in proveDHTuple(g, c1, gX, c2) (hidden). inline_single_use_vals therefore saw count==1 and dropped the ValDef while leaving stale ValUse references — the post-CSE renumber emitted ValUse(4) with no matching ValDef. Adding the arm matches Scala's structural model (CreateProveDHTuple(gv, hv, uv, vv) — confirmed via Metals on sigmastate-interpreter) and lets all c2 usages count correctly. Closes 20B. 2. mir/lower.rs lowered 'groupGenerator' as the standalone GlobalVars::GroupGenerator opcode (1 byte). NODE v6.1.x emits PropertyCall(Global, GROUP_GENERATOR_METHOD) (4 bytes). Switched the lowering to PropertyCall to match. Closes the remaining 3B.

…on class in segregation roundtrip Root cause: replace_all() at mir/cse.rs:5735+ was missing an Expr::Append arm. When inline_single_use_vals substituted ValUse(N) → rhs at use sites nested inside an Append, the substitution silently failed to recurse, leaving a stale ValUse(N) that referenced an inlined-and-removed ValDef. Subsequent renumber assigned the dangling ValUse's id to a slot that collided with an unrelated val's id, producing a ValUse whose stored type didn't match the ValDef it now resolved to. For chaincash_reserve.es this manifested as ValUse(13, SColl(SByte)) inside the `aBytes ++ message ++ ownerKey.getEncoded` Append chain, with ValDef(13) actually being `history: SAvlTree`. The constant-segregation roundtrip's Append parser then failed type-checking with `Expected Append input param to be a collection; got input=SAvlTree`, triggering the silent fallback at compiler.rs:91 to non-segregated ErgoTree (header 0x00 instead of 0x10). Adding the Append arm completes the missing recursion. Per WS-E methodology: replace_all arm additions are monotonic (they complete a recursion that was failing — cannot introduce regressions assuming the recursion logic itself is sound), unlike direct_children arm additions (which alter usage counting and CAN regress, as confirmed by the prior falsified -77 result on the speculative GroupElement-arm hypothesis). Effect: - chaincash_reserve.es: 549B (RT-ERR fallback, type collision) → 550B (RT-ERR fallback, ValDefIdNotFound(26) — different missing arm, deferred to S70). Δ=-62 → -61. Type-collision class CLOSED for this fixture; remaining gap is in another not-yet-covered walker variant. - SigmaFi OpenOrderToken: flipped from RT-ERR fallback (573B) to RT-OK segregation-on (641B). Still USED NODE (node 638B) but with a different underlying state. - All 8 prior sig-15 LOCAL MATCH fixtures unchanged (skyharbor, phoenix-full, spectrum-n2t, spectrum-t2t, dexy_bank_full, ergoraffle, duckpools, ergomixer). - 11/14 ecosystem batch LOCAL MATCH unchanged. Validation: - lib 233/233, conformance 154/154, lib-ignored 10/10, batch_node_byte_match 1/1 - ecosystem batch 11/14 LOCAL MATCH (unchanged) - sig-15: 8/15 LOCAL MATCH (unchanged) Sig-15 progress: 8/15 (S69 partial — Append arm; chaincash deferred). Known-future-arms catalogued in MANIFEST §"Smallest diffs" — each requires its own concrete failure trace per WS-E methodology before addition.
…alUse buried in Exponentiate.right Closes the second replace_all gap in chaincash's segregation roundtrip. After S69's Append arm, a dangling ValUse(26, SColl(SByte)) remained in the IR — buried as Exponentiate.right via ByteArrayToBigInt → CalcBlake2b256 → Append-chain. The recursion in replace_all bottomed out at `other => other.clone()` for Exponentiate (not in the match arms), so inline_single_use_vals never substituted the inner ValUse. Adding the Exponentiate arm completes the recursion. chaincash's segregation roundtrip now advances past `ValDefIdNotFound(26)` to a new failure class (`UnknownMethodId(MethodId(4), 7)` — GroupElement.multiply absent from the METHOD_DESC registry at sgroup_elem.rs:32). That's an S71 entry point, captured in the local handoffs. Validation: 233 lib + 154 conformance + 10 lib-ignored + 1 batch_node_byte_match green; 11/14 ecosystem LOCAL MATCH preserved; 8/15 sig-15 LOCAL MATCH preserved (chaincash still on no-seg fallback at 551B, was 550B pre-S70 — same fallback path, +1B structural drift from the now-correct substitution). Sig-15: 8/15 unchanged. Per WS-E methodology, replace_all arm additions are monotonic-safe (complete a missing recursion → cannot regress correctly-structured logic).
…eplace_all MultiplyGroup arm — chaincash flips to with-segregation Two coupled changes to close chaincash's segregation roundtrip: 1. lower.rs: switch SGroupElement.multiply(other) lowering from MethodCall(MULTIPLY_METHOD, [other]) to canonical Expr::MultiplyGroup, mirroring the existing `.exp` → Exponentiate pattern two arms above. The MethodCall path is rejected by the deserializer because GroupElement.multiply (MethodId 4) is defined at sgroup_elem.rs:71 but never appended to METHOD_DESC at sgroup_elem.rs:32 (only getEncoded + negate are registered). MultiplyGroup is the canonical opcode form — same as Exponentiate for `.exp`. 2. cse.rs: add MultiplyGroup arm to replace_all. Switching the lowering alone re-exposes ValDefIdNotFound(26) — the dangling ValUse(26, Coll[Byte]) that S70's Exponentiate arm closed is now buried inside MultiplyGroup.right (was previously inside MethodCall.args[0], which IS in replace_all's match arms). MultiplyGroup wasn't, so inline_single_use_vals' replacement walk bottomed out at the `other => other.clone()` fallthrough. Result: chaincash flips from no-seg fallback (header 0x00) to with-segregation (header 0x10), 550B → 613B local vs 611B node (+2B residual, deterministic across 3 runs — separate constants- segment encoding drift at byte 12, S72-class). Validation: 233 lib + 154 conformance + 10 lib-ignored + 1 batch_node_byte_match green; 11/14 ecosystem LOCAL MATCH preserved; 8/15 sig-15 LOCAL MATCH preserved (chaincash still in USED NODE since +2B from exact match, but structural class is closed).
…ft, not constants encoding — defer to S73
S72 falsified the constants-segment encoding hypothesis. Both LOCAL and NODE pools have
identical multisets of 32 constants in different order; segment length is byte-equal.
The +2B is in the body — specifically a CSE inlining-decision divergence in the inner
action==0 block:
- LOCAL extracts 3 ValDefs that NODE inlines:
zBytes (1x), noteTokenId (1x), receiptOut.R6[Int].get (2x CSE'd)
- LOCAL inlines 1 ValDef that NODE extracts:
positionBytes = longToByteArray(position) (2x)
Body breakdown: LOCAL inner 138B vs NODE 121B (+17), LOCAL trailing 263B vs NODE 278B
(-15), net +2.
HIR's has_shared_field_in_clean_scope anchors zBytes (value.slice shared with aBytes)
and noteTokenId (noteInput.tokens shared with noteValue) so MIR CSE can see and extract
the shared FieldAccess. By the end of MIR's CSE pipeline both anchors are dead (count==0,
verified via tree-walk after sequential_renumber). MIR's inline_single_use_vals only
handles count==1, so dead anchors ride through to serialization as redundant wrapper
bytes.
Naive fix (add count==0 drop to inline_single_use_vals) orphans the Const literals
inside the dropped RHSs, breaking chaincash's segregation roundtrip and falling back to
no-seg at 493B. Reverted; deferred to S73-class joint solve with SkyHarbor SigUSDV1
(+15, with-seg, RT-OK, anchor vals dead at end of CSE — same shape).
… MIR has redundant anchors — chaincash 613B → 609B with-seg, RT-OK
…eArray, ByteArrayToLong, DecodePoint, MultiplyGroup, Exponentiate) — chaincash positionBytes preserved as ValDef
…k rescue mode — chaincash receiptOut.R6 over-extraction closed (12 inner items match NODE)
…ng arms + AvlTree.get MethodCall lowering
emit_deps had no recursion arms for Exponentiate / MultiplyGroup / DecodePoint /
LongToByteArray / ByteArrayToLong, so DFS over chaincash's properSignature
conjunct fell through `_ => {}` and never reached its inner ValUses. value /
aBytes / positionBytes / maxValueBytes were tail-appended out of order,
displacing receiptOut to inner item ergoplatform#6 instead of ergoplatform#12 (NODE's position).
Adding the five arms makes emit_deps walk the full c4 body, emitting deps in
post-order and putting receiptOut last — matches NODE's depthFirstOrderFrom
schedule exactly, so the constants pool order also matches byte-for-byte.
Residual 3B in the body was the AvlTree.get encoding: dedicated TreeLookup
opcode (0xb7) vs Scala's MethodCall(GET_METHOD) (0xdc 0x64 0x0a). Switched the
HIR→MIR lowering at mir/lower.rs to emit MethodCall(GET_METHOD); only chaincash
uses AvlTree.get so the change is fixture-isolated.
chaincash_reserve: 608B → 611B = NODE (LOCAL MATCH). Sig-15 9/15.
Ecosystem 11/14 (preserved). All 233 lib + 154 conformance + 10 ignored tests pass.

Brings the
