Exit code 0, empty stderr. Reported upstream as gHashTag/t27#2508. The triggers are ordinary, correct t27: an `if` whose condition is not parenthesised, `match` in any position, `let x = if ...`. And an implicit tail return lowers to `expr;` WITH a semicolon, so the function returns (). Measured before and after, 91 functions across the seven specs: declared in specs 91 -> 91 emitted 86 -> 91 (5 were being deleted outright) unimplemented!() 14 -> 0 artifact matches a fresh gen-rust: 7 of 7 Five functions were not stubs. They were absent - four in m3_multihop, one in production_deployment - which is worse than a stub, because a stub at least announces itself. `unimplemented!()` turns out to be the empty-body fallback, so counting stubs understates the damage. Each spec was rewritten into the subset the parser accepts - parenthesised conditions, explicit returns - and its artifact REGENERATED, never hand edited. `gen/` is generated and this repository's own law forbids touching it; a proposed patch that edited gen/rust/adaptive_retry.rs directly was rejected for that reason before any of this landed. Equivalence was proven by execution, not argument. adaptive_retry was compared against a transcription of the pre-change source over its complete input space - 132,096 comparisons, run twice, once with overflow checks on and once off - with a census confirming 63,521 of those inputs actually panic under checks, so the panic-domain comparison is not vacuous. Every existing overflow and wrap point is preserved exactly, including two latent ones in adaptive_retry that are real bugs and were deliberately left alone: changing them would change behaviour, which is not what this commit is for. Two exceptions, disclosed rather than buried: pattern_predictor is the one genuine spec bug, not a workaround. Its source line read `return ((array >> 64) & 0xFFFFFFFFFFFFFFFF;` - unbalanced parentheses, and a `>> 64` on a u64. Repairing it changed get_sample_array_lower from u32 to u64, which IS a behaviour change with no prior caller: exhaustive 8-slot pack-and-read round trips go from 1020 of 2048 failing to 0 of 2048, with no cross-talk. The old accessor was wrong. olsr_routing still fails bare rustc, and every one of its 25 errors is on a line this commit did not touch: the spec declares u32 while its own expressions treat an entry as 64 bits and the table as 256. Constant shifts past the type width are a hard error. Widening it is a real change to the data model and is left for someone who can decide it rather than guess. m3_multihop's remaining rustc failure is only `serde` not being passed as an extern; the crate already declares that dependency and the file builds under cargo.

Nine were gone - not stubbed, gone - and nothing anywhere reported it: exit 0, empty stderr, and a `t27c parse` that cheerfully returns 12 FnDecl nodes. The cause is a single character. Line 80 read if (index == 6) { { return ((array >> 8) & 0xFFFFFFFF) as u32; } with one brace too many, and line 316 carried a stray `}` after the module's own closing brace which balanced the token count. So the file looked clean. The parser's `recover_to_stmt_boundary` then swallowed the whole remainder of the module into that one failed statement, taking every function declared after line 80 with it. That is the shape of gHashTag/t27#2508: a real typo, silently amplified into nine deletions by a recovery that reports nothing. The typo is ours. The silence is the compiler's. Verified per function rather than assumed: eight of the nine were extracted VERBATIM into a probe and lower perfectly; the ninth does too. None of them contained a rejected construct. They were collateral, all of it. Two further defects, found while restoring them and fixed here because they were compile blockers: - line 67 used `||` between two u64 shift chains where the other seven slots use `|`. It lowered to a Rust logical-or on u64 and produced two of the three E0308 errors in the old artifact. - line 154 called `get_tr_score_value`, a name that exists nowhere in this submodule. t27c lowers a call to an undefined function without complaint, so it only became visible once the function was no longer deleted. Four token edits, no logic rewritten. The artifact was regenerated by redirecting the compiler, never hand-edited, and is byte-identical across three consecutive generations. Equivalence proven by execution: 55.9 billion differential comparisons against an oracle transcribed independently from the spec text, 0 mismatches. The first run finished in 8 seconds because LLVM proved both sides equal and deleted the loop bodies - a false pass, caught and rebuilt with black_box on every input and every result, which took it to 225 seconds. Coverage is exhaustive where the domain allows: all 2^32 inputs against each of the eleven single-argument functions, all 256^4 tuples against both packers. Independently audited: the four token edits applied mechanically to HEAD reproduce the delivered spec exactly, comment for comment.

All four predate that commit. Reproduced before changing anything: 232, 57, 3, false. Nothing in the repository consumes this layout yet - gen/rust/ is excluded from compilation in src/lib.rs, and no file outside the spec and its artifact names trust_manager - so each of these was cheap now and expensive later. The three directions were confirmed with the operator, not guessed. verified is 8 bits and stays 8 bits. create_trust_relationship masks `verified & 0xFF` and the witness was 1000, stored as 232. The test now passes 200. Widening the field would have made last_verified a real timestamp at the cost of a u64 return type and the 4x8 layout every other packed word in this module uses. The trust array is 8-bit lanes, in both directions. create_trust_array packs at shifts 56..0 - byte lanes - while its callers handed it 32-bit create_trust_score words, so the score byte was shifted out before any OR happened and only the negative-interaction byte reached the slot. get_trust_score then extracted `& 0xFFFFFFFF` from lanes eight bits wide, splicing neighbours together. Three edits, chosen as one: - create_trust_array masks each argument `& 0xFF`. Its contract is now a bare score value rather than a packed word, and the comment says so. - get_trust_score masks `& 0xFF`, matching the lane it reads. - find_most_trusted (8 sites) and should_route_via_node call get_trust_score directly. The old get_trust_score_value(get_trust_score(...)) shifted a value at most 8 bits wide right by 16 and always read zero. MAX_NODES stays 8. The alternative - two 32-bit slots - would have cut the trust table to two nodes and deleted six of find_most_trusted's eight branches, against the spec's own "8-node trust storage". update_trust_score_increases asserted >= 60 from interaction counts that give 57. Five positive and five negative start at 50; adding three and one gives 8 of 14. The bound is now > 50, mirroring update_trust_score_decreases' < 50. The arithmetic was right and the test was wrong. should_route_via_node_false was passing for the wrong reason: it read garbage from an overlapping slot that happened to fall under 90. It now passes because 75 >= 90 is false. Verified rather than assumed. A function count alone cannot catch a statement dropped inside a test block, so the AST was counted too: fn declared / pub fn emitted 21 / 21 FnDecl / TestBlock / assert 21 / 17 / 23, matching the spec rustc --crate-type lib exit 0, 0 errors spec test assertions 23 pass, 0 fail (was 4 fail) cargo check --all-targets exit 0 The artifact was regenerated by redirecting the compiler, never hand edited: generated to a temporary file, validated there, then produced again by the prescribed command and confirmed byte-identical, so a failing generator could not have truncated it in place. One pre-existing violation left alone. Line 2 of all 68 files under gen/rust/ carries a non-ASCII em dash in t27c's own header, against L3 PURITY. It is the compiler's header, not this change, and it is committed at HEAD already; fixing it means editing t27c, which L0b assigns elsewhere.

Two more specs is a modest number and it is the honest one: most of what was left is not the specs' fault. Two separate causes were separated rather than lumped together. Stale artifacts. Much of gen/rust/ was output from a July compiler and had drifted badly from its own spec - cache_management carried `let;` fragments and a type-erased `Vec<>` where the spec says `[u32; MAX_ENTRIES]`, and failed with 27 errors that no longer exist. Simply regenerating with the current t27c, changing no spec at all, took cache_management 27 -> 6 and bandwidth_allocator 15 -> 2. All 18 artifacts here are byte-identical to a fresh `t27c gen-rust`, checked file by file; none was hand-edited, which this submodule's own law forbids. Genuine spec faults, in eight specs: a wrong-arity call, a call to a name that exists nowhere, an integer literal outside its declared type. Those were repaired. What was deliberately NOT repaired, and this is the substance of the change: every remaining failure was attributed, and the ones belonging to the backend were left alone. The largest is one defect - t27c's gen-rust never emits `mut` on a function PARAMETER, although `collect_mutable_names` already computes the exact set of names that need it and the StmtLocal arm already consults that set for locals. gen_fn simply never asks. Eight errors across cache_management and bandwidth_allocator are that one omission; scratch copies with nothing but the `mut` token added compile clean. Renaming a parameter or adding a shadow local would have silenced it while hiding a one-line fix from its author and putting dead bindings into the source of truth. Same reasoning for `create_packet_color(type: u32, ...)` in traffic_animator: `type` is legal in t27 and the backend must escape it as `r#type`. Renaming it would change the module's public interface to suit a broken tool. Three specs carry non-ASCII characters, which L3 forbids. Pre-existing, counts unchanged by this commit, and no line added here is non-ASCII - recorded as standing debt rather than swept in.
