t27b: a module var written at the top of a test is a write to module state (Closes #6911) - #6965

Conversation
…state Since #6295 the reference (block_fresh_binding in bootstrap/src/compiler.rs) no longer binds a top-level write to a module `var` in a test as a fresh `const`; gen-zig prints the plain write, and t27c test-report passes it. t27b still refused it as StmtAssign(module var in test). The refusal is removed; the write takes the module-var store path a fn body already uses. Dogfood spec first: specs/tri/t27b/conformance/module_var_in_test.t27 (reference: 6 pass, 0 vacuous). A test-local `var` that shadows a module var and a write inside an invariant stay refused. Rust edit under the owner's approval on epic #6063 (label owner-approved-foreign); files listed in tools/policy/foreign-exceptions.txt. Closes #6911 Refs #6063 Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
The test that wrote a test-local var twice also hit StmtAssign(reference redeclares), a separate family; it now writes only module state. On the lab: reference 6 pass, 13 runtime asserts, 0 vacuous; t27b 6 pass, 13 runtime asserts; three mutants (wrong value, leaked state, sign) fail.

Lab run on 8aa626c (mismatch 0, reference_disagree 0): formal_tb and vcd_trace_tb move from blocked to pass, and module_var_in_test passes with 13 runtime asserts. Scoped hand edit of the ledger; cap 57 -> 55. The #6911 approval note joins the existing #6864 block in foreign-exceptions.txt instead of repeating the paths.

Lab check of the merged head 86b4a6b, which carries #6900's code as well as this PR's. Everything was built on the Railway lab (aarch64, qemu): cargo test -p t27b gives 108 passed, 0 failed, 14 suites. Both conformance specs pass with runtime asserts: module_var_in_test 6/6 with 13 asserts, brace_invariant 1/1 with 14. formal_tb passes 10/10 and vcd_trace_tb 6/6. The 9 specs #6900 unlocked all still pass. |

…s, ties toward zero, NaN 0xFE01, exponent mask (#6940) (#6969) * fix(spec-guards): ring-096 and specs/numeric/formats.t27 agree on f32, as the gf16 SSOT says (Closes #6887) check_ring_spec_drift.py reported the pair DRIFTED (5 of 6 shared signatures differ) and failed spec-guards on master and every PR. Both sides disagreed with specs/numeric/gf16.t27 (L6): - spec: gf16_to_f32, ternary_to_f32 and quantize_value returned gf16 (lowered to u16); the SSOT decoder gf16_decode_to_f32 returns f32. Now f32; tests/invariants compare the f32 directly. Two false test claims fixed: 1.0 is 0x3E00 under bias 31 (not 0x3C00), and -0.5/0.5 are not fixed points of ternary quantize/dequantize. - ring: the public API used f64 where spec and SSOT say f32. Now f32; the f64 arithmetic stays private (narrowing is exact for GF16 values). 42/42 crate tests pass (rustc 1.99, t27c Railway lab). The Rust edit is an owner-approved-foreign exception scoped to #6887. Refs #6488 Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> * seal(numeric/formats): reseal after the f32 return types (Refs #6887) Resealed on the t27c Railway lab with master 75cf4e5 t27c (t27c seal specs/numeric/formats.t27 --save; tri seals sync-twins). spec_hash matches the local spec (sha256 b5fed047...b088). Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> * fix(numeric/formats): shift constants are u8, as in the gf16 SSOT (Refs #6887) ExpShift and SignShift read u5 and u4; specs/numeric/gf16.t27 declares EXP_SHIFT and SIGN_SHIFT as u8. gen-rust passed u5/u4 through verbatim, so the generated Rust did not compile and the spec-guards differential step could not even build its harness for ring-096. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> * seal(numeric/formats): reseal after the u8 shift constants (Refs #6887) Resealed on the t27c Railway lab with master 75cf4e5 t27c. spec_hash matches the local spec (sha256 51e4a456...a417a831). Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> * numeric/formats: implement the codec bodies; ring-096 encodes denormals The six functions in specs/numeric/formats.t27 had empty bodies, so the generated Rust could not run and ring-096 had nothing to be compared with. They now have bodies built from the numeric SSOT (GF16 [S|E6|M9], bias 31, specs/numeric/gf16.t27 and FORMAT-SPEC-001.json): - gf16_to_f32 decodes zero, denormals, normals, +/-Inf and NaN exactly. - f32_to_gf16 rounds to nearest with ties away from zero, as gf16_encode_f32 does; overflow goes to +/-Inf, NaN to 0x7F01. - f32_to_ternary / ternary_to_f32 / format_bytes / quantize_value. Eight new tests, including an exhaustive decode-then-encode round trip over all 65536 codes. Trit members are spelled Trit::pos because gen-rust only learns an enum's name when it emits the enum, and a `use`-imported enum is emitted after the functions. ring-096 encoded every denormal at twice its value and 2^-31 as +0: its scale-down loop ran to e = 0 instead of stopping at e = 1. Fixed, with the same exhaustive round-trip test on the ring side (#6887 foreign exception). Refs #6893 #6488 Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> * spec-guards: published figures follow the corpus; harness learns enums and floats published_figures.py: the pins had not moved since 5b2f8e4 (#5613), where every figure still equals its pin. Eight drifted as merges landed. Each new pin names the merges that moved it, counted per merge with the file's own regexes; no matcher, exit code or self-check changed (#6899). ring_spec_differential.py (#6893): - enum parameters and returns, with variants paired by name across case; an enum that does not pair one to one is refused; - an f32/f64 input grid (both zeros, ties, denormals, the GF16 overflow edge, +/-Inf, NaN), with floats compared by {:?}; - a producer that panics on one side only is counted as a disagreement instead of killing the harness. Three new negative controls in --self-check. Both Python files are listed in tools/policy/foreign-exceptions.txt under owner-approved-foreign issues #6893 and #6899. Refs #6893 #6899 #6488 Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> * numeric/formats: build the decoded NaN through a typed local gen-zig typed `(pos_inf() - pos_inf()) as f32` as an integer-to-float cast (@floatFromInt of an f64), so the seal reported the Zig tests as blocked. With a typed f64 local all 34 tests and the comptime invariants compile and pass under zig 0.16.0 on the lab. Refs #6893 Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> * reseal formats.t27 after NaN typed-local fix (lab, 34/34) Refs #6893 Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> * published figures: test blocks 15611 -> 15614 after master merged #6892 and #6880 #6892 added one test block and #6880 added two; counted per merge with the checker's own regex. No matcher changed. Refs #6899 Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> * fix(numeric): settle the four gf16.t27 self-contradictions against FORMAT-SPEC-001 (#6940) D1 no subnormals: FORMAT-SPEC-001 value_formula has no subnormal clause, so E=0, M!=0 is normal and |x| < 2^-31 flushes to signed zero (as gf16_v2_mul.v flushes underflow). D2 round to nearest, ties toward zero: frozen_silicon_anchor.rounding_mode is "ties-to-zero (frozen)". D3 canonical NaN 0xFE01 (gf16_v2_mul.v emits 16'hFE01); every E=63, M!=0 code is NaN. D4 extract_exponent is (x & EXP_MASK) >> EXP_SHIFT. gf16.t27 now compiles and its 201 tests run; compiling exposed three wrong bodies (fmod sign, exp overflow, negate of zero) that are fixed with it. formats.t27 and ring-096 follow the same decisions; ties, overflow tie, no-subnormal and NaN cases are pinned with concrete bit patterns. Closes #6940 Refs #6488 Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> * seal: reseal gf16 and Formats on the t27c lab after #6940 gf16.t27 now compiles: its seal records tests 201/201 instead of "blocked: does not compile". Formats 34/34. check_seal_currency on the lab: STALE generated-code hash 0, ring/spec drift CONVERGED 3, differential ring-096 vs formats.t27 138/138 agree. Refs #6940 Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> * published figures: re-pin after master moved to 33e61b3 (Refs #6899) spec-guards was red on the PR head because master merged under it. Counted per merge with the file's own regexes, 2838800..33e61b3: - test blocks 15614 -> 15714: #6966 +16, #6943 +6, #6938 +6, #6828 +38, #6749 +6, #6900 +1, #6747 +27 (= +100).

The census gate passes on the merge: the quiet census move (159 -> 160) that failed cli-tri was re-blessed on master by #6924, so nothing is re-blessed here. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> * published figures: test blocks 15714 -> 15720 after master merged #6965 (Refs #6899) #6965 added specs/tri/t27b/conformance/module_var_in_test.t27 (+6 test blocks). Master alone measures 15712 at 38a6e30; + 8 from this PR = 15720. x.len field reads unchanged at 2149. Census gate passes.

OTP's restriction is kept: child_spec_valid refuses a significant permanent child and any significant child under AUTO_NEVER. auto_shutdown_after_exit counts only a child that is not restarted (should_restart) and that ended on its own: a child its supervisor stopped never ends the supervisor.

Every call now carries its chain: one bit per slot of the callers blocked on it (this caller included) and their count. call_admit refuses a callee already on the chain with CALL_CYCLE before any send, alias or monitor, and a depth past CALL_MAX_DEPTH (8) with CALL_TOO_DEEP. A cycle is named before the depth. Prior art, read for this commit: Erlang's gen_server:call refuses only a call to self (calling_self) and leaves longer cycles to the 5000 ms timeout; Orleans deadlocks a non-reentrant cycle until the call times out; Dapr refuses a call back into the chain unless reentrancy is on and bounds a reentrant chain at maxStackDepth 32. Choices beyond the issue, stated in the spec: - The slot, not the pid, is on the chain: a runtime blocked on a chain is alive, so its slot is not reused while the chain lasts. A caller that dies and whose slot is reused makes a call to the new owner read as a cycle; that chain's reply goes to a dead alias, so nothing is lost. - The model tracks slots 0..63 (CHAIN_SLOTS, one u64). A slot past it is never on the chain: a call to it is admitted unchecked, and a cycle through it waits out the timeout, as in Erlang. An invariant checks the Queen's 23 processes (control.t27's 4 domains of 4 agents, as literals per the owner rule) fit, given a runtime that hands out the lowest free slot. - CALL_MAX_DEPTH 8 is chosen, not measured; Dapr's 32 is for a reentrant chain. - A send carries no chain: it waits for nothing, so it closes no cycle.

A child being stopped counts until its EXIT. children_after_exit keeps a restarted child's place, so a restart never asks the bound. The issue asked for a per-domain MAX_CHILDREN constant. It is not added: control.t27 already owns DOMAIN_CAP and placement's P_WAIT, so a second constant would be a second home for one number. The bound is a parameter the Queen fills from DOMAIN_CAP; a refused start leaves control.t27's P_WAIT (the task stays unleased), never a drop. Prior art: Elixir DynamicSupervisor checks max_children in handle_call, does not check it on restart, and deletes a terminated child only after its exit; a Temporal worker with no free slot stops polling. Mutants: tool 8 of 8 killed (start_answer 4, children_after_exit 4); hand 8 of 8 killed. Without the new invariant, START_OK 0 -> 1 and START_MAX_CHILDREN 1 -> 0 both survive, so the invariant is what pins them. 59 pub fn, 14 invariants, 26 tests, 26 passed, 0 vacuous. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> * docs(now): actors max children -- counts and whole-file run after #7005 (Refs #7005) 59 pub fn, 14 invariants, 26 tests; whole file 304 mutants, 298 killed, the same 6 equivalents. The "35 mutants added since" line is replaced by a claim the survivor lines check: none sits on a line #7002-#7005 added. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> * spec(queen): an effects journal so a new lease holder does not repeat what the old one did (Refs #7006) A fence stops the old holder's writes, not what it already did outside: a crash after a push but before the next journal write left the new holder to push again, open a second pull request or post a second comment. control.t27 section 7 adds the journal's contract: - an entry per effect, intent written before it and done after it, at the holder's fence; the key is (task, kind, target), not the position (a model turn is not deterministic, so Temporal/Restate's replay by position does not apply) and not the fence (every retry must see the same key, as Temporal's run id + activity id leaves the attempt out); - effect_action: a stale fence does nothing; no entry runs; done skips; an open intent looks the effect up at GitHub where it can (push, pull request, comment) and runs again where it cannot (a model call repeats once per crash that leaves its intent open); - look_wait_seconds: after a DOWN, a look waits out GitHub's 10 s request limit, so a request the old holder sent cannot land after the look; an invariant keeps that wait under the first heartbeat; - effect_may_repeat: a push (leased) and a pull request (one per head, 422) are refused by the receiver; a comment can still repeat behind a partition, and the journal's marker only makes the copy detectable. actors.t27 reclaim_wait_seconds points at the journal (doc only; the spec does not import control.t27, T7). Counts printed by commands: control.t27 42 pub fn, 8 invariants, 15 tests, 15/15 zig, 0 vacuous; actors.t27 59/14/26 unchanged, 26/26. tri mutate spec --fn on the 7 new functions (lab, #7043 build): 36 of 36 killed after one gap: dropping `seconds_since_down > LIMIT` survived (at 11 s both paths return 0); asserts at 12 s and 3600 s now kill it (the u32 subtraction underflows). Hand constant mutants 16/16 killed; without the_effect_codes_are_distinct the four DO_* mutants survive, so that invariant is what pins the action codes. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> * docs(now): control.t27 effects journal -- design, counts and mutation run (Refs #7006) The entry now closes #7006 too: the journal key, effect_action, look_wait_seconds and effect_may_repeat, the answer to the issue's Restate question, and the counts and mutation results printed by commands in the same tick (control.t27 42/8/15, 36 of 36 tool mutants after one gap, 16 hand constant mutants). Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> * spec(queen): name the assumption under the journal's look wait (Refs #7006) GitHub documents that it terminates a request after 10 s; it does not document that a write it terminated is never applied later. The look wait rests on that assumption, so the doc now says so, and says what fails if it is wrong: a comment can repeat even after a DOWN, and its marker shows the copy. Doc only; 15/15 tests unchanged.

Closes #6108 Co-Authored-By: Claude Opus 5 <noreply@anthropic.com> * fix(codegen): gen-rust enum order and gen-zig float-call cast (Closes #6941) gen-rust recorded an enum's name only when it emitted the enum. `use` splices an imported enum after the functions, so every function lowered `Trit.pos` as a field access (E0423) and a switch arm `.neg` as a binding that matches every value (E0170). The names are now collected before the first function is emitted. gen-zig's is_float_expr had no arm for calls, so `(half() - quarter()) as f32` and `half() as f32` were lowered to `@floatFromInt`, which Zig refuses on an f64. A call to a function the spec declares with a float return type is now a float expression. Regression specs: specs/compiler/rust_enum_order.t27 and specs/compiler/zig_float_call_cast.t27. Eleven seals resealed on the t27c lab; their generated output changed in the same two ways. FROZEN_HASH moved. Owner exception: label owner-approved-foreign on #6941.

Both sides disagreed with specs/numeric/gf16.t27 (L6): - spec: gf16_to_f32, ternary_to_f32 and quantize_value returned gf16 (lowered to u16); the SSOT decoder gf16_decode_to_f32 returns f32. Now f32; tests/invariants compare the f32 directly. Two false test claims fixed: 1.0 is 0x3E00 under bias 31 (not 0x3C00), and -0.5/0.5 are not fixed points of ternary quantize/dequantize. - ring: the public API used f64 where spec and SSOT say f32.

They now have bodies built from the numeric SSOT (GF16 [S|E6|M9], bias 31, specs/numeric/gf16.t27 and FORMAT-SPEC-001.json): - gf16_to_f32 decodes zero, denormals, normals, +/-Inf and NaN exactly. - f32_to_gf16 rounds to nearest with ties away from zero, as gf16_encode_f32 does; overflow goes to +/-Inf, NaN to 0x7F01. - f32_to_ternary / ternary_to_f32 / format_bytes / quantize_value. Eight new tests, including an exhaustive decode-then-encode round trip over all 65536 codes. Trit members are spelled Trit::pos because gen-rust only learns an enum's name when it emits the enum, and a `use`-imported enum is emitted after the functions. ring-096 encoded every denormal at twice its value and 2^-31 as +0: its scale-down loop ran to e = 0 instead of stopping at e = 1.

OTP's restriction is kept: child_spec_valid refuses a significant permanent child and any significant child under AUTO_NEVER. auto_shutdown_after_exit counts only a child that is not restarted (should_restart) and that ended on its own: a child its supervisor stopped never ends the supervisor. The supervisor exits with X_SHUTDOWN (AUTO_SHUTDOWN_REASON). One rule beyond the issue, from OTP's own warning: auto_shutdown_sticks says a supervisor with auto_shutdown must not be a permanent child of its parent, or the shutdown is undone at once.

Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> * spec(queen): a call into its own chain is refused at once, and the chain is bounded (Refs #7004) A runtime runs one turn at a time and a caller blocks, so a call cycle (A calls B, B calls A) left both sides waiting out their timeouts and looking like two hung turns (#6990). Every call now carries its chain: one bit per slot of the callers blocked on it (this caller included) and their count. call_admit refuses a callee already on the chain with CALL_CYCLE before any send, alias or monitor, and a depth past CALL_MAX_DEPTH (8) with CALL_TOO_DEEP. A cycle is named before the depth. Prior art, read for this commit: Erlang's gen_server:call refuses only a call to self (calling_self) and leaves longer cycles to the 5000 ms timeout; Orleans deadlocks a non-reentrant cycle until the call times out; Dapr refuses a call back into the chain unless reentrancy is on and bounds a reentrant chain at maxStackDepth 32. Choices beyond the issue, stated in the spec: - The slot, not the pid, is on the chain: a runtime blocked on a chain is alive, so its slot is not reused while the chain lasts. A caller that dies and whose slot is reused makes a call to the new owner read as a cycle; that chain's reply goes to a dead alias, so nothing is lost. - The model tracks slots 0..63 (CHAIN_SLOTS, one u64). A slot past it is never on the chain: a call to it is admitted unchecked, and a cycle through it waits out the timeout, as in Erlang. An invariant checks the Queen's 23 processes (control.t27's 4 domains of 4 agents, as literals per the owner rule) fit, given a runtime that hands out the lowest free slot. - CALL_MAX_DEPTH 8 is chosen, not measured; Dapr's 32 is for a reentrant chain. - A send carries no chain: it waits for nothing, so it closes no cycle. Counts, printed by commands: 57 pub functions (54 before), 13 invariants (11), 25 tests (24); all 25 pass, vacuous passes 0 of 25; parse, typecheck, gen-rust, gen-verilog, gen-c exit 0. tri mutate spec --fn (lab build of #6993 + #7022, --jobs 8): chain_has 6 of 6 killed, chain_add 5 of 5, call_admit 4 of 4.

A child being stopped counts until its EXIT. children_after_exit keeps a restarted child's place, so a restart never asks the bound. The issue asked for a per-domain MAX_CHILDREN constant. It is not added: control.t27 already owns DOMAIN_CAP and placement's P_WAIT, so a second constant would be a second home for one number. The bound is a parameter the Queen fills from DOMAIN_CAP; a refused start leaves control.t27's P_WAIT (the task stays unleased), never a drop. Prior art: Elixir DynamicSupervisor checks max_children in handle_call, does not check it on restart, and deletes a terminated child only after its exit; a Temporal worker with no free slot stops polling. Mutants: tool 8 of 8 killed (start_answer 4, children_after_exit 4); hand 8 of 8 killed.

Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> * spec(queen): an effects journal so a new lease holder does not repeat what the old one did (Refs #7006) A fence stops the old holder's writes, not what it already did outside: a crash after a push but before the next journal write left the new holder to push again, open a second pull request or post a second comment. control.t27 section 7 adds the journal's contract: - an entry per effect, intent written before it and done after it, at the holder's fence; the key is (task, kind, target), not the position (a model turn is not deterministic, so Temporal/Restate's replay by position does not apply) and not the fence (every retry must see the same key, as Temporal's run id + activity id leaves the attempt out); - effect_action: a stale fence does nothing; no entry runs; done skips; an open intent looks the effect up at GitHub where it can (push, pull request, comment) and runs again where it cannot (a model call repeats once per crash that leaves its intent open); - look_wait_seconds: after a DOWN, a look waits out GitHub's 10 s request limit, so a request the old holder sent cannot land after the look; an invariant keeps that wait under the first heartbeat; - effect_may_repeat: a push (leased) and a pull request (one per head, 422) are refused by the receiver; a comment can still repeat behind a partition, and the journal's marker only makes the copy detectable. actors.t27 reclaim_wait_seconds points at the journal (doc only; the spec does not import control.t27, T7). Counts printed by commands: control.t27 42 pub fn, 8 invariants, 15 tests, 15/15 zig, 0 vacuous; actors.t27 59/14/26 unchanged, 26/26. tri mutate spec --fn on the 7 new functions (lab, #7043 build): 36 of 36 killed after one gap: dropping `seconds_since_down > LIMIT` survived (at 11 s both paths return 0); asserts at 12 s and 3600 s now kill it (the u32 subtraction underflows). Hand constant mutants 16/16 killed; without the_effect_codes_are_distinct the four DO_* mutants survive, so that invariant is what pins the action codes. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> * docs(now): control.t27 effects journal -- design, counts and mutation run (Refs #7006) The entry now closes #7006 too: the journal key, effect_action, look_wait_seconds and effect_may_repeat, the answer to the issue's Restate question, and the counts and mutation results printed by commands in the same tick (control.t27 42/8/15, 36 of 36 tool mutants after one gap, 16 hand constant mutants). Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> * spec(queen): name the assumption under the journal's look wait (Refs #7006) GitHub documents that it terminates a request after 10 s; it does not document that a write it terminated is never applied later. The look wait rests on that assumption, so the doc now says so, and says what fails if it is wrong: a comment can repeat even after a DOWN, and its marker shows the copy. Doc only; 15/15 tests unchanged.

What
t27b now treats a top-level write to a module
varinside atestas a write to module state. That is what the reference does: since #6295,t27c gen-zigno longer binds such a write as a freshconst(block_fresh_bindinginbootstrap/src/compiler.rs). Before this PR, t27b refused it asStmtAssign(module var in test), which was rank 1 intri t27b next. The refusal is removed, and the write takes the store path that a fn body already uses.Still refused (unchanged):
varthat shadows a module varvar. That isStmtAssign(reference redeclares). It is also stale since t27c gen (Zig): test bindings shadow module vars, redeclare locals, and inherit param renames #6295, but it is a family of its own and is left for its own PR.Dogfood spec first
