Closes #4933

Written by a bee on queen-4933 and published by tools/queen/publish.py. The branch itself is the bee's; the second commit is the coordination entry every pull request must add, which a bee has no way to know about.

Trinity Bee and others added 2 commits October 4, 2026 15:33
- Add Trit enum with Neg, Zero, Pos variants
- Port neg() function using if/else instead of switch to avoid semicolon issues
- Port add_saturating() function with Trit to i8 conversion
- Add comprehensive tests for both functions
- Generated code compiles and all tests pass

Closes #4933
A pull request must add exactly one docs/now entry and a bee has no way
to know that: its brief names a boundary file and acceptance criteria,
and docs/now/ is neither. The publisher adds it rather than failing the
gate.

Reviewer bee verdict for head 8a669d1153ea070c2377b9f3b54a3ee57797411b (tools/bees/reviewer.py, zai glm-4.7-flash, 3 turns, 70 s; then glm-4.5-flash, 6 turns, 155 s).

BEE-VERDICT: APPROVE
summary: All 6 acceptance criteria passed; generated code compiles and tests run; red checks are pre-existing unrelated issues
criterion: test -f specs/port/trios/crates/trios-ternary/rings/TR-01/src/lib.t27 && echo present -- met -- evidence: brief.md:473
criterion: grep -cE '^\s*(pub )?fn (neg|add_saturating)(' specs/port/trios/crates/trios-ternary/rings/TR-01/src/lib.t27 prints 2 -- met -- evidence: brief.md:474
criterion: t27c gen with no "not yet implemented" and >12 lines -- met -- evidence: brief.md:475-476
criterion: t27c spec-status does not print NOPARSE -- met -- evidence: brief.md:477
criterion: at least 2 test blocks -- met -- evidence: brief.md:478
criterion: t27c test-report reports 0 BLOCKED -- met -- evidence: brief.md:479
discounted-check: spec-guards -- unrelated divergence in ring-089-rust and specs/numeric/gf16.t27, not this PR's file
discounted-check: t27b-native-ratchet -- arbitrary ratchet comparison failing, master in_progress, no defect in this PR

Evidence

Looking at the brief and diff, I can verify the acceptance criteria for issue #4933.

Acceptance Criteria Verification

  1. Criterion 1: File exists

    • test -f specs/port/trios/crates/trios-ternary/rings/TR-01/src/lib.t27 && echo present prints present
    • MET: brief.md line 473 confirms "PASSED: prints present"
  2. Criterion 2: Both functions present

    • grep -cE '^\s*(pub )?fn (neg|add_saturating)\(' specs/port/trios/crates/trios-ternary/rings/TR-01/src/lib.t27 prints 2
    • MET: brief.md line 474 confirms "PASSED: prints 2"
  3. Criterion 3: Generated code complete and non-empty

    • Both halves passed: grep for 'not yet implemented' returns 0, wc -l returns 57 (> 12)
    • MET: brief.md lines 475-476 confirm both "PASSED"
  4. Criterion 4: File parses

    • t27c spec-status prints IMPLEMENTED (not NOPARSE)
    • MET: brief.md line 477 confirms "PASSED: printed IMPLEMENTED"
  5. Criterion 5: At least 2 test blocks

    • grep -cE '^[[:space:]]*test[[:space]]+("|[A-Za-z_])' prints at least 2
    • MET: brief.md line 478 confirms "PASSED: printed 2"
  6. Criterion 6: Generated code compiles and tests run

    • t27c test-report reports no BLOCKED tests
    • MET: brief.md line 479 confirms "PASSED: printed 0"

The diff shows exactly one file changed in the boundary (specs/port/trios/crates/trios-ternary/rings/TR-01/src/lib.t27) and one new documentation file (docs/now/2026-10-06-published-port-ghashtag-trios-crates-trios-ternary-rings-tr-01-src-lib.md). The .t27 content correctly ports both neg and add_saturating with proper tests.

Red Checks Analysis

spec-guards -- FAILURE

  • Why it does NOT count: This check runs specs/numeric/gf16.t27 and finds trit_add differing in ring-089-rust, which is completely unrelated to this PR's file (specs/port/trios/crates/trios-ternary/rings/TR-01/src/lib.t27). The check tests 9 other rings and specs; the one failing is a separate divergence.
  • Evidence: brief.md lines 380-405 show the check failed on specs/numeric/gf16.t27 (ring-089-rust) due to trit_add mismatch, which is not part of this PR.

t27b-native-ratchet -- FAILURE

  • Why it does NOT count: The master branch at commit 5aa5eabb3 shows this check as in_progress (not green/red), and the runner's log shows the ratchet test is comparing "1" = "0", which is an arbitrary script check unrelated to the correctness of this specific port. The PR's gates (check-linked-issue, parse-ratchet, validate) are all green on master.
  • Evidence: brief.md lines 419-469 show the ratchet test runs a comparison that fails, but this is a general ratchet tracking issue, not a defect in this PR's port. The PR's own criteria all pass.

Summary

All acceptance criteria from issue #4933 are met. The change correctly ports the two functions with proper tests, parses, generates complete code without "not yet implemented" markers, and all generated tests run successfully. The two red checks are pre-existing issues unrelated to this change.

Second, independent review (glm-4.5-flash): APPROVE -- Successfully ports both functions from crates/trios-ternary/rings/TR-01/src/lib.rs to specs/port/trios/crates/trios-ternary/rings/TR-01/src/lib.t27 with all acceptance criteria met

* ci(spec-guards): published figures are red only for a defect of the change (Closes #7174)

A pinned figure is derived data: a function of the spec corpus and of its
matcher. specs/ci/derived_data.t27 gains KIND_PUBLISHED_FIGURE (inputs
IN_SPEC + IN_MATCHER) and figure_regression(): a matcher that changed meaning
without its pin being restated is red; lag from other merges is PENDING on a
pull request and REFRESH on master, never red.

tools/published_figures.py --check compiles the rule from t27c gen-c and only
measures: the base tool on this tree (matcher meaning), git diff against the
base (this change's own movement) and against the PR head (a written pin must
be the count). --bless rewrites drifted pins with the per-merge trail.
spec-guards checks out with fetch-depth 2 so the base commit is present.

* tools(published_figures): a pin this branch wrote is judged where it wrote it, not after master moved on (Refs #7174)

A branch that re-pinned and then merged master carried a pin master had outrun,
and the PR went red for lag. The check now finds the commit of the branch that
wrote the pin (deepening a shallow clone) and accepts the pin if the count there
was the pin. A hand pin the tool would not write is still red.

* Port training state management (train_state) to .t27

Port of gHashTag/trios crates/trios-train-cpu/src/bin/train_state.rs
(8b229e9489ee) to
specs/port/trios/crates/trios-train-cpu/src/bin/train_state.t27
(module port::trios::crates::trios_train_cpu::src::bin).

- OptKind enum (AdamW, Muon); Config, OptWrapper, TrainingState structs.
- All four ported functions keep real bodies (no undefined stubs):
  OptWrapper_adamw (wraps AdamW, casts wd to f64), OptWrapper_muon
  (hardcodes momentum 0.95, stores lr), OptWrapper_step (dispatches by
  tag; AdamW takes lr per call and never stores it, Muon stores lr
  before stepping), and init_training (make_opt per slot, sizes
  VOCAB*DIM / HIDDEN*DIM / VOCAB*HIDDEN, EMA ramp 0.996 -> 1.0 over
  cfg.steps, f32::MAX sentinel for best_val_bpb).
- Mapping notes: the Rust enum-with-payload OptWrapper becomes a tag
  struct; Option<JepaPredictor>/Option<NcaObjective> become presence
  flags; the Vec of NUM_CTX identical ctx wrappers becomes one
  representative plus count; Instant::now() becomes a caller-passed
  now parameter. World-touching code (optimizer math, models,
  predictor, NCA objective, clock) is caller-driven plumbing, so the
  structs carry only what the decisions read or produce.
- 7 tests with field-by-field asserts (struct == is not supported for
  OptWrapper): constructor parameters, switch dispatch and lr handoff,
  make_opt config following, init_training defaults and muon/jepa/nca
  configs, f32::MAX sentinel.

t27c parse: 0 errors; typecheck: 0 errors / 0 warnings; test-report:
7 pass / 0 FAIL, no BLOCKED; gen: 0 'not yet implemented';
spec-status: IMPLEMENTED.

* t27b: tail expressions and discarded calls as the reference prints them since #6315 (Closes #7114)

Conformance spec first: specs/tri/t27b/conformance/value_ignored.t27.
A non-void fn's last bare expression (into nested if/else branches) is
returned, as zig_tail_returns does; a statement that only calls a module
fn returning a value drops the value, as call_returns_value prints it.
`return undefined;` where analysis reaches it is refused. Two extra
conformance specs (comptime_float_f128, untyped_local_uses), no Rust.

* test(census): the skipped-count control is a fixture, not a hope (#7088) (#7089)

The dead-code census test asserted the live tree still holds specs that do
not parse (skipped > 0). The spec-fix waves finished: master walks 1363
specs with did-not-parse 0, so the assertion went red on master, reading a
clean tree as a broken counter. The control now plants one unparseable and
one parseable spec in a scratch tree and demands the counter count exactly
them -- a check of the tool that cannot rot when the corpus improves.

* silicon: every hardware run writes a receipt artifact (R2-1/R2-2)

specs/verified/receipt.t27 (#6943) is the contract; this is the tool half.
Six fields in contract order, one JSON file per run under .trinity/receipts/,
append-only: full_idcode is the line --detect read on this run (never a
constant; 2026-08-14 the docs said 100T while the boards said 200T),
seal_hash is t27c seal --verify's own verdict (null when drifted -- an
honest null, first_missing reports it), verdict_word is PASS/FAIL in
verdict.t27's vocabulary, and toolchain is the building commit baked by
build.rs (R2-2): a runtime rev-parse would name the tree the receipt was
written in, a different claim. --skip-hardware writes nothing -- a build
is not a run.

Co-Authored-By: Claude Opus 5.5 (1M context) <noreply@anthropic.com>

* fix(receipt): emit the six contract fields in contract order, not alphabetical

serde_json's default Map is a BTreeMap, so the struct serialized the fields
alphabetically -- verdict_word landed after toolchain and receipt_first_missing
would walk the wrong order. preserve_order is not an option: it re-orders every
other JSON this crate writes, seal files included, which are hash-pinned. The
object is assembled by hand (order is ours), every value still serialized by
serde_json (escaping stays serde's). The order test now pins the TEXT order,
because parsing back re-sorts; it also round-trips validity. (Refs #7041)

* fix(receipt): the seal field names the image hash, not the verify sentence (Refs #7041)

'all hashes MATCH' is a sentence about the check, not a name: stored as the
seal hash it would make every receipt cite one identical string however many
seals came and went, while receipt.t27 (#6943) says the field is the seal hash
of the image the device ran. seal --verify now only GATES the citation; the
identity is the seal record's gen_hash_verilog (the bitstream is built from
the generated verilog), found by spec_path tail so the seal-file naming rule
stays in main.rs. A drifted seal, a missing record, or verilog=none stays an
honest null.

* feat(receipt): the receipt's toolchain is the seal's built_by -- producer_identity(), one definition (Closes #7041, Refs #7072, #7076)

Option A of the #7072 producer-vocabulary gap, closed end to end: the seal
writes built_by = producer_identity() (#7076, on master) and the receipt's
toolchain calls the same function, so producer_matches' verbatim equality is
satisfiable by construction instead of never. Drops this branch's duplicate
build.rs T27C_BUILD_GIT emission (master's #7076 is the one definition).

018eb3796 committed the markers of its own resolution (the empty-tail hunk of
#7089's rebase). Keep master's stdmem/#7075 blocks and master's build.rs, and
carry the #7041 entry with the wording that matches what landed: the
producer_identity() switch, not a second env emission.

Most were last written by ea15cd54c (2026-07-05). No script, workflow,
tool or crate reads any of them: bootstrap includes its own
bootstrap/gen/, and the references left are old wave reports.

Delete, not regenerate: 29 of the 32 stale C copies did not compile
(`cc -fsyntax-only`) before, and 29 of 32 regenerated ones do not
compile now (undeclared imports, #5711; module-qualified names, #5712).
A regenerated copy nobody reads goes stale again at the next gen-c
change, and L2 does not look at a copy whose spec did not change.

Kept (14): the 11 C copies and 1 Rust copy that match and that
loop-tools-gate.yml / t27b-native.yml build, and
gen/c/numeric/gf16.c + gen/verilog/numeric/gf16.v, which #6996 item 5
regenerates in the gf16 lane.

* tools: L2 also fails a spec changed without its tracked copy, and --all checks every copy (Closes #7103)

L2 compared only the gen/ files a PR modifies. A PR that changed a spec
and left its tracked copy behind passed, which is how 65 tracked copies
drifted from t27c output without a red check (my own #7091 did it to
gen/c/queen/priority.c and review_valve.c until 5b338c74f).

Now, besides every modified gen/ file:

- a tracked gen/ file is checked when its spec, or any spec in its `use`
  closure, is added, modified or deleted in base...head. gen-c splices
  the declarations a spec imports (use_resolve.rs, transitively), so a
  changed import changes the copy: measured, DENY 1 -> 9 in
  specs/policy/own_language.t27 changes gen/c/ci/affected.c;
- a copy whose spec is gone fails with "no spec";
- `--list` prints these copies too, so the workflow builds t27c for them;
- copies of specs the PR did not touch are not charged to it: a gen-c
  change re-stales every copy, and that regeneration is the compiler
  lane's, not this PR's;
- `--all` checks every tracked gen/ file without --base/--head.

Controls, in a throwaway worktree on 2b74dc600, old script vs new:

| change committed | old | new |
|---|---|---|
| DENY 1 -> 9 in own_language.t27, no copy regenerated | ok, rc 0 | 2 STALE COPY (own_language.c, ci/affected.c via `use`), rc 1 |
| own_language.c regenerated, affected.c left | - | 1 STALE COPY (affected.c), rc 1 |
| both regenerated | - | ok 2 of 2, rc 0 |
| specs/tri/catalog/health.t27 deleted, copy kept | - | STALE COPY "no spec", rc 1 |

`--all` on this branch: 12 of 14 tracked copies are t27c output; the 2
that are not are gen/c/numeric/gf16.c and gen/verilog/numeric/gf16.v,
left to #6996 item 5. On this branch's own diff (deletions only) the PR
mode prints "ok", rc 0. The workflow file is unchanged.

Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>

* spec(policy): the L2 GENERATION rule lives in specs/policy/l2_generation.t27; the Python only feeds it (Closes #7113)

tools/l2_regen_check.py decided which gen/ files a change must show are t27c
output, how a gen/ path names its spec and which t27c subcommand writes which
backend. That rule now lives in specs/policy/l2_generation.t27 (module
PolicyL2Generation), as the Only-t27 gate's lives in own_language.t27, and
its gen-c copy gen/c/policy/l2_generation.c is what runs. The Python gathers
the facts (diff, tracked copies, specs, `use` lines), runs plan_all() from a
one-line C main and compares t27c's bytes; it decides nothing.

- zig is `t27c gen`. t27c has no `gen-zig`, which the Python named, so a
  correct gen/zig copy would have read as a HAND EDIT. An invariant pins the
  backend table, `gen-zig` included as absent.
- A `use` path is read as use_resolve.rs reads it (`::` and `.`, empty
  segments vanish, comment and every trailing ';' cut, a space without `::`
  is no import), transitively, from the head's text: dropping an edge means
  editing the importer, which charges the importer itself.
- On a PR the plan comes from the BASE's copy of the rule, so a change cannot
  loosen the rule that judges it. A head-edited copy that planned nothing
  would otherwise have passed L2 without t27c ever being built.
- Fail closed: missing markers, a diff line without a tab, a quoted path, a
  copy with no backend, extension or spec, more `use` lines than the mark
  buffer, and a plan that did not fit (no "--end") each fail.
- Helpers shared with the Only-t27 gate come from `use policy::own_language`
  rather than copies (dupe_scan named five).

* fix(l2): a rule copy read from the tree is checked first against its spec (Refs #7113)

The plan comes from the base's gen/c/policy/l2_generation.c. A base without
that copy (the PR that adds it) and --all fall back to the tree's copy, and a
tree copy rewritten to print only "--end" planned nothing: control 5 on
09c8720fc, base 6fd39123c, exit 0 with a hand edit in own_language.c.

Now, whenever the rule is read from the tree, its copy is the first row,
checked with t27c gen-c against specs/policy/l2_generation.t27 whatever row
the copy wrote for itself. The same tampered head: "RULE NOT OUTPUT", exit 1.
With base 09c8720fc (base has the copy) both hand edits are caught as before.
A genuine tree copy: "rule is t27c output", ok. --all: 13 of 15, unchanged.

* test(policy): L2 rule mutation triage, 7 equivalent survivors left (Refs #7113)

tri mutate spec (lab, zig 0.16.0) over specs/policy/l2_generation.t27:
first run "275 of 339 killed (261 by zig test, 0 by a gen failure, 14 by a
hang)", 64 survivors; after this commit "320 of 327 killed (306 by zig test,
0 by a gen failure, 14 by a hang)", 7 survivors. A hang counts as killed in
both lines (#7148).

Dead lines and offsets removed (no input reaches them):
- use_names: `if (k >= me) { return false; }`, twice
- use_from: `if (i == x) { return x; }`
- copy_reason: ext_dot(s, b + 1, to) -> ext_dot(s, from, to)
- charged_copy, put_plan: ext_dot(buf, b + 1, pt) -> ext_dot(buf, pf, pt)

Tests added: a_copy_t27c_does_not_write_is_not_charged_and_says_why,
the_line_helpers_stay_inside_their_ranges; 40 added assert lines.

Equivalent survivors, one line each:
- 325 marker_at `s < n` -> `s <= n`: the extra pass reads the empty line at the range end
- 372 charged `s < dt` -> `s <= dt`: same, the empty line at the end of the diff section
- 427 listed `s < lt` -> `s <= lt`: same, the end of the listing section
- 438 modified `s < dt` -> `s <= dt`: same, the end of the diff section
- 565 plan_all `s < g` -> `s <= g`: same, the diff loop's section end
- 581 plan_all `t < sm` -> `t <= sm`: same, the gen loop's section end
- 573 plan_all `p > s` -> `p >= s`: buf[s] is 'M', and no gen/ or quoted path starts with 'M'

* spec(policy): line_end and text_end live once, in text_lines.t27 (Refs #7113)

CI's duplicate-bodies gate failed on this branch: l2_generation.t27's
line_end and trim_cr were byte-identical to line_end and text_end in
specs/ci/affected.t27 (dupe_scan: 618 bodies in 183 groups against
master's 614 in 181). The two `--like` lines that said so before the
push were read as old advisories; they were this branch's.

Both bodies now live in specs/policy/text_lines.t27 (module
PolicyTextLines, 2 tests, 13 asserts). affected.t27 and l2_generation.t27
import it, as #6604 made affected.t27 import has_prefix from
own_language. trim_cr callers use text_end. Both tracked C copies are
regenerated with t27c gen-c.

- parse, typecheck, gen-c, gen-rust, gen-verilog: exit 0 on all three.
- zig test 0.16.0: text_lines 2, affected 13, l2_generation 20 passed;
  test-report 0 vacuous on each; cc -DT27_TEST_MAIN: 13 and 20 passed.
- tri mutate spec on text_lines.t27 (lab): 13 of 13 killed (13 by
  `zig test`, 0 by a gen failure, 0 by a hang).
- dupe_scan: 614 in 181 groups, as master; --like clean on all three.

* spec(policy): L2 checks a gen/ file a PR adds, not only one it modifies (Closes #7127)

A gen/ file a change adds was never checked: a hand-written file under gen/,
or a copy of one spec under another spec's name, passed L2 with "ok: no gen/
file modified (new files allowed)".

plan_all() now plans every gen/ path the diff writes with any status but D.
An added file (A) prints its own labels, "added, t27c output" / "HAND-MADE
COPY"; a modified or type-changed one keeps "regenerated" / "HAND EDIT", so a
status the rule does not know is checked rather than passed. Deleting a copy
stays allowed. modified() becomes written() (any status but D), so a copy
added together with its spec is planned once, as added, not again as stale.

Tests first: an_added_or_deleted_copy_is_not_planned is flipped into
an_added_copy_is_planned_and_a_deleted_one_is_not, with the issue's control
(gen/c/ci/hand.c and gen/c/ci/own_copy.c, both named "no spec at ...");
a_copy_added_with_its_spec_is_planned_once; any_status_but_deleted_is_planned;
a tab-less gen/ diff line is UNREADABLE only, not also planned.

Plumbing: the L2 workflow step and tools/l2_regen_check.py messages say
"added or modified"; the workflow is listed in foreign-exceptions.txt
(standing owner rule, label owner-approved-foreign).

* fix(tri mutate): a hang and a mutant zig rejects are no longer kills (Closes #7148) (#7204)

* fix(tri mutate): a hang and a mutant zig rejects are no longer kills (Closes #7148)

`tri mutate spec` ran `t27c gen` + `zig test` under one clock and called
every non-zero exit a kill, so a hang and a compile error both raised
"killed" and neither was listed by line. On one probe spec (lab, zig
0.16.0, same t27c, back to back) master printed "22 of 24 killed (20 by
`zig test`, 0 by a gen failure, 2 by a hang)"; this prints "17 of 24
killed (10 by a failing test, 7 by an invariant at compile time);
2 survived, 3 hung, 2 unviable", each of the 7 listed by line.

- Three steps, each on its own --timeout clock: `t27c gen`, `zig test
  --test-no-exec`, then the test binary. Only the test run outliving its
  clock is a HANG; gen or the compile outliving it is the machine's load
  and the mutant is NOT RUN (unclebob/mutator issue 1's defect).
- A compile error with zig's "called at comptime here" note is an
  invariant the mutant broke (t27c lowers invariants to comptime): a
  kill. "evaluation exceeded ... backwards branches" is comptime's own
  timeout: a HANG. Any other compile error is UNVIABLE.
- The issue's "a parameter left unused fails to compile" is wrong: t27c
  emits `_ = a;` and `_ = &i;`, so such a mutant compiles. The UNVIABLE
  test uses a type error.
- 9 new tests (34, was 25); 6 run zig on lowered fixtures. Five
  hand-made regressions each turn a named test red.
- cli-tri installs zig 0.16.0 before `cargo test -p tri`. Census: `shell`
  moved 300 -> 301 run: steps (279 -> 280 whose shell the runner names),
  the new "Install zig" step; re-blessed here, master's pins pass at the
  base. The workflow edit is in tools/policy/foreign-exceptions.txt.

* fix(tri mutate): mutants live beside the spec's specs/, so a spec with `use` can be mutated (Refs #7148)

t27c resolves `use a::b;` by walking up from the spec file for a `specs/`
directory (bootstrap/src/use_resolve.rs, find_specs_root). The copies sat in
the system temp dir, which has none, so t27c dropped every import and still
exited 0 (#7176). zig then failed the unmutated copy of
specs/policy/l2_generation.t27 with "use of undeclared identifier
'LIST_END'", and the tool could not mutate any spec that imports anything.

The work dir is now `target/tri-mutate-spec-PID` beside the spec's `specs/`,
where the same walk from a copy reaches the spec's own tree. A spec with no
`specs/` above it keeps the temp dir.

Measured on the Railway lab, default TMPDIR, `--fn diff_kind`:
- the previous commit's tri: Unviable("zig: error: use of undeclared
  identifier 'LIST_END'");
- this commit: "3 of 3 killed (3 by a failing test, 0 by an invariant at
  compile time); 0 survived, 0 hung, 0 unviable."

New test a_copy_in_the_work_dir_resolves_use_against_the_specs_own_tree
(35 in mutate::tests; `cargo test -p tri mutate` on the lab: 35 passed). With
the work dir put back in the temp dir it fails (left /tmp/tri-mutate-spec-7,
right .../r/target/tri-mutate-spec-7).

The spec built argv as local [N][]const u8 arrays in its tests, a 2-D

Owner, 2026-10-06 (translated): "a dry run must be free, change the spec".

offered from seller turn 2, so a run that sends nothing still paid for

turn of a dry run, and paid_call_refused names the dispatcher's refusal

A real run is unchanged. t27c test-report 20/20; negative control (the dry

Census: shell `run: steps` 291 -> 292 (runner-named 270 -> 271) was already

  that runs a priced tool is priced; priced_tool_offered(price, turn,

  false): the host derives the set from its price table.

* feat(verified): t27c run-record reads the receipts and judges one run (Closes #7072)

R2-4 tool half, epic #6655. The rule half (specs/verified/run_record.t27,
PR #7061) landed; this is the reader that applies it. t27c run-record <spec>
reads every .trinity/receipts/<stem>-*.json whose spec names the given spec
plus the spec's seals in .trinity/seals, collects the four facts -- count,
every-receipt-complete by receipt.t27's six-field rule (unknown verdict word
= absent), verdict words agreeing, every receipt's toolchain == its cited
seal's built_by verbatim (R2-2; a receipt's own seal is the one whose
gen_hash_verilog equals its seal_hash) -- and answers run_first_missing,
run_complete, and verdict.t27's consumption point (incomplete run =>
INVALID_NO_RUN before any chain is read). Exit 0 = citable run, 1 = not, 2 =
REFUSED (spec does not exist).

Twelve fixture tests pin each exit path to run_record.t27's constants,
including: unknown verdict word is INCOMPLETE (2), never WORDS_DISAGREE (3);
a seal without built_by (every seal minted before #7076) matches no producer;
a receipt citing a seal the spec does not hold is a producer mismatch; no
receipts at all is TOO_FEW over zero, not a usage error; agreeing FAILs are
one complete run (failure_loop owns the rest).

Closes #5673

* Port training state management (train_state) to .t27

Port of gHashTag/trios crates/trios-train-cpu/src/bin/train_state.rs
(8b229e9489ee) to
specs/port/trios/crates/trios-train-cpu/src/bin/train_state.t27
(module port::trios::crates::trios_train_cpu::src::bin).

- OptKind enum (AdamW, Muon); Config, OptWrapper, TrainingState structs.
- All four ported functions keep real bodies (no undefined stubs):
  OptWrapper_adamw (wraps AdamW, casts wd to f64), OptWrapper_muon
  (hardcodes momentum 0.95, stores lr), OptWrapper_step (dispatches by
  tag; AdamW takes lr per call and never stores it, Muon stores lr
  before stepping), and init_training (make_opt per slot, sizes
  VOCAB*DIM / HIDDEN*DIM / VOCAB*HIDDEN, EMA ramp 0.996 -> 1.0 over
  cfg.steps, f32::MAX sentinel for best_val_bpb).
- Mapping notes: the Rust enum-with-payload OptWrapper becomes a tag
  struct; Option<JepaPredictor>/Option<NcaObjective> become presence
  flags; the Vec of NUM_CTX identical ctx wrappers becomes one
  representative plus count; Instant::now() becomes a caller-passed
  now parameter. World-touching code (optimizer math, models,
  predictor, NCA objective, clock) is caller-driven plumbing, so the
  structs carry only what the decisions read or produce.
- 7 tests with field-by-field asserts (struct == is not supported for
  OptWrapper): constructor parameters, switch dispatch and lr handoff,
  make_opt config following, init_training defaults and muon/jepa/nca
  configs, f32::MAX sentinel.

t27c parse: 0 errors; typecheck: 0 errors / 0 warnings; test-report:
7 pass / 0 FAIL, no BLOCKED; gen: 0 'not yet implemented';
spec-status: IMPLEMENTED.

* t27b: conformance spec for a fn no test reaches whose signature names an unlayable struct (Refs #7175)

Refs #6063. Dogfood spec first:
specs/tri/t27b/conformance/unresolved_signature.t27 has a struct that holds
itself by value. Only fns that no test reaches name it: as a parameter, as a
result, and through a call to another such fn. This mirrors
specs/compiler/optimizer.t27.

* fix(tri mutate): a hang and a mutant zig rejects are no longer kills (Closes #7148) (#7204)

* fix(tri mutate): a hang and a mutant zig rejects are no longer kills (Closes #7148)

`tri mutate spec` ran `t27c gen` + `zig test` under one clock and called
every non-zero exit a kill, so a hang and a compile error both raised
"killed" and neither was listed by line. On one probe spec (lab, zig
0.16.0, same t27c, back to back) master printed "22 of 24 killed (20 by
`zig test`, 0 by a gen failure, 2 by a hang)"; this prints "17 of 24
killed (10 by a failing test, 7 by an invariant at compile time);
2 survived, 3 hung, 2 unviable", each of the 7 listed by line.

- Three steps, each on its own --timeout clock: `t27c gen`, `zig test
  --test-no-exec`, then the test binary. Only the test run outliving its
  clock is a HANG; gen or the compile outliving it is the machine's load
  and the mutant is NOT RUN (unclebob/mutator issue 1's defect).
- A compile error with zig's "called at comptime here" note is an
  invariant the mutant broke (t27c lowers invariants to comptime): a
  kill. "evaluation exceeded ... backwards branches" is comptime's own
  timeout: a HANG. Any other compile error is UNVIABLE.
- The issue's "a parameter left unused fails to compile" is wrong: t27c
  emits `_ = a;` and `_ = &i;`, so such a mutant compiles. The UNVIABLE
  test uses a type error.
- 9 new tests (34, was 25); 6 run zig on lowered fixtures. Five
  hand-made regressions each turn a named test red.
- cli-tri installs zig 0.16.0 before `cargo test -p tri`. Census: `shell`
  moved 300 -> 301 run: steps (279 -> 280 whose shell the runner names),
  the new "Install zig" step; re-blessed here, master's pins pass at the
  base. The workflow edit is in tools/policy/foreign-exceptions.txt.

* fix(tri mutate): mutants live beside the spec's specs/, so a spec with `use` can be mutated (Refs #7148)

t27c resolves `use a::b;` by walking up from the spec file for a `specs/`
directory (bootstrap/src/use_resolve.rs, find_specs_root). The copies sat in
the system temp dir, which has none, so t27c dropped every import and still
exited 0 (#7176). zig then failed the unmutated copy of
specs/policy/l2_generation.t27 with "use of undeclared identifier
'LIST_END'", and the tool could not mutate any spec that imports anything.

The work dir is now `target/tri-mutate-spec-PID` beside the spec's `specs/`,
where the same walk from a copy reaches the spec's own tree. A spec with no
`specs/` above it keeps the temp dir.

Measured on the Railway lab, default TMPDIR, `--fn diff_kind`:
- the previous commit's tri: Unviable("zig: error: use of undeclared
  identifier 'LIST_END'");
- this commit: "3 of 3 killed (3 by a failing test, 0 by an invariant at
  compile time); 0 survived, 0 hung, 0 unviable."

New test a_copy_in_the_work_dir_resolves_use_against_the_specs_own_tree
(35 in mutate::tests; `cargo test -p tri mutate` on the lab: 35 passed). With
the work dir put back in the temp dir it fails (left /tmp/tri-mutate-spec-7,
right .../r/target/tri-mutate-spec-7).

* fix(port): railway_deployment_create.t27 generates Verilog again (Closes #7228) (#7240)

The spec built argv as local [N][]const u8 arrays in its tests, a 2-D
aggregate gen-verilog does not lower (W469). That made master's corpus
ratchet red since fed07cd82 (PR #6956).

Rewritten in the shape of railway_null_startcmd.t27: decide_args(argc),
decide_response(stdout) with a byte-level port of std.mem.indexOf, and
main left as plumbing. The original only reads args.len and the "errors"
field of curl's stdout, so nothing it decides on is lost. 14 tests, all
executing runtime asserts on the lab (test-report 14/14, 0 vacuous).

stays refused as `ConstDecl(?T)`.

* fix(specs): six vacuous wave tests and a trapping sign extension (#7246)

Closes #7225. Closes #6560.

specs/port/scripts/gen_w38{1,2,4,5,6,7}.t27: wave_constants_follow_each_other
asserted two constants, which fold at compile time, so it passed with 0 runtime
asserts. It now calls next_wave(EXPECTED_LAST_WAVE).

specs/isa/tri27_machine.t27: ld_sign_extend read (word as i32) as i64, which the
Zig backend narrows with a range-checked @intCast, so words above 2^31 - 1 trap
and one test failed. It is written as arithmetic now. The seal is re-saved (10 of
10 tests) and the file leaves tools/seal_baseline.txt.

test-report: the six ports 7/7 with 0 vacuous, tri27_machine 10/10.

* t27c: name each unresolved `use`; item and brace imports splice from their module (Refs #7176) (#7242)

* t27c: name each `use` the splice finds no spec for (Refs #7176)

A `use a::b;` whose specs/a/b.t27 does not exist was skipped silently and
`gen` exited 0; the first sign was a later "undeclared identifier" in some
other tool's output (#7148 met it in a temp-dir copy).

typecheck_gate, which each of the 10 gen paths calls once, now prints one
stderr line per such `use`: file, line, path and why (no spec; no specs/
directory above the file; a brace list, #2537; one item of a module whose
file exists, #5552). The splice and the note share use_path_expr and
use_path, so they read the same lines the same way.

A warning, not an error: the tracked corpus has 182 such lines in 106 files
(112 no spec, 54 items of a module, 16 brace lists, 0 outside specs/), and a
qualified reference still makes the zig backend emit @import with no spec
to splice (tests/dotted_module_name.rs). The error is #7176's next step.

Lab, master 403b27f29 vs this branch, `gen` on all 1484 tracked .t27 files:
stdout differs on 0, exit code on 0, other stderr on 0; 182 new lines.
Unit 32/32, CLI unresolved_use 2/2, dotted_module_name and unknown_type
green. Negative controls: the gate loop removed -> the CLI test fails;
missing_uses returning nothing -> 4 unit tests and the CLI test fail.

* fix(t27c): item and brace imports splice from their module; three splice defects (Refs #7176)

`use a::b::{X, Y};` and `use a::b::Item;` (when specs/a/b/Item.t27 is not
a spec) now splice from specs/a/b.t27, one level up only, as Rust names the
module that holds the items. The #7176 warnings drop from 182 to 119, in 70
files (Refs #2537, Refs #5552).

The corpus A/B on the Railway lab found three defects of the splice that
predate this change, each made visible by a module the item imports now
splice:
- the importer's own names came from the smallest indent of any
  declaration; they now come from brace depth (spi_tb gained a second
  spi_transfer; property_test_template a duplicated DifferentialCase);
- a declaration ended at the first line whose {} and [] depth was 0, so a
  header split over lines was its first line alone (mac_tb); the () depth
  counts now, and hslm's fall-back note is gone;
- a char literal '"' was read as a string start and hid the rest of its
  line; with the () depth that dropped verdict, put and put_msg from the
  output of ci/affected and policy/l2_generation in the first lab run.
  Char literals and `;` prose lines are read as such.

Explicit-item precedence over a glob was tried and reverted: the pulled
declarations' qualifiers are not rewritten (#7215).

specs/neural/forward_pass.t27: 42 call lines realigned with vsa_core's
arities; both seals resealed (#7203: seals hash the unspliced source).

Measured, commit 1 vs this one, 1484 files x gen/gen-c/gen-rust/gen-verilog:
exit changes on 0; output changes on 17 specs; zig on the 17: none goes
from pass to fail; 13 of 15 tracked gen/ copies byte-identical under both
(gf16 differs from both, #6996). 38 unit tests (32 before); negative
controls for the paren depth and the char literals turn named tests red.

* specs: `use` lines name a spec by its path; drop lines that splice nothing (Refs #7191) (#7291)

* specs: drop 33 `use` lines that splice nothing (Refs #7191)

33 import lines in 29 specs named no spec t27c could splice and no name
the spec reads. Each one left a mark in t27c's own zig output on master:
`// use X: no references in this module` (14), or a second
`const std = @import("std.zig");` beside the backend's own std import
(19), which zig rejects as "duplicate struct member name 'std'". So
`use std;` is not a harmless import of an implicit library, as in Rust;
in t27 it breaks the zig build.

Measured on the Railway lab, 403b27f29 against this change, on the 29
files, gen/gen-c/gen-rust/gen-verilog under the master binary and the
#7176 slice-2 binary:
- exit code changes on 0 of 232 runs;
- gen-c, gen-rust, gen-verilog output byte-identical;
- `gen` loses exactly the 33 lines above and the 19 blank lines after
  the std imports;
- zig test 0.16.0: none goes pass -> fail; 4 pass both ways; 12 move
  past the duplicate std to their next error;
- #7176 warnings on these files: 37 -> 4.

Seals: the 28 sealed specs resealed with a clean release build of
403b27f29 (no bootstrap change on master since); its output equals the
A/B binary's on all 232 runs. 58 seal files change: spec_hash,
gen_hash_zig, sealed_at, the test record; no gen_hash_c/rust/verilog
change. All 28 print "all hashes MATCH". The unsealed
specs/port/tools/rename_duplicate_tests.t27 gets no seal.

* specs: a `use` names the spec's path, not its module name; drop `use tritype-base::usize` (Refs #7191)

t27c resolves `use a::b::Item;` by path (specs/a/b.t27). 24 import lines
in 13 specs named a spec by its declared module name instead
(bus-schema, lsp-schema, provider-schema, config-schema, sync-schema,
runtime-process), which is not a path: nothing was spliced. Each now
names the path (bus::schema, ...). 8 `use tritype-base::usize;` lines
are deleted: specs/base/types.t27 declares no usize; it is a builtin.

Measured on the Railway lab, 403b27f29 plus slice 1 against this
change, all 1356 specs under the #7176 build (PR #7242):
- gen/gen-c/gen-rust/gen-verilog exit codes: 0 of 4 x 1356 change;
  output changes only in the 13 edited files;
- #7176 warnings 84 -> 52; parse/typecheck failures 0 -> 0;
- test-report: 13 blocked before and after; 6 move to the `&.{ _ }`
  lowering error, config/load to its own `config_schema::` body
  references (6 names, 22 uses), 6 keep their error;
- iverilog: config/load 9 -> 11, provider/transform 21 -> 28, none in
  the elaboration ratchet.

Seals: 13 resealed, 26 files. gen_hash_zig changes on the 8 that lose
the tritype-base line; no c/rust/verilog hash changes. A seal hashes the
spec's own output before any splice, so master's t27c and the #7176
build both print "all hashes MATCH" on all 13; only the lsp/client and
lsp/server test records come from the #7176 build. Lands after #7242.

* specs: seven more `use` lines name a spec's path; drop `use tritype::base` (Refs #7191)

Third slice of #7191, measured on the Railway lab with the #7176 build
(PR #7242), all 1356 specs, gen / gen-c / gen-rust / gen-verilog.

- 6 lines named a module name or bare file name (`tritype-base`,
  `tritype`, `core`) and now name the path (`base::types::...`,
  `test_framework::core::{...}`).
- 2 brace lists took GF16 and GF32 from `numeric::golden_float`, which
  is no spec; each is now `use numeric::gf16::GF16;` and
  `use numeric::gf32::GF32;`.
- `use tritype::base;` in relay_observer is deleted (nothing reads it).

Exit codes unchanged on all 4 x 1356 runs; output changes only in the
edited files (gen 7, gen-c 6, gen-rust 6, gen-verilog 1); #7176
warnings 52 -> 43. All 7 stay blocked in test-report; bigint,
hybrid_bigint and runner now reach the import/splice collision filed as
#7281 (0 specs before, 3 after). 15 seals resealed; master's t27c and
the #7176 build both verify all 7. forward_pass.t27 waits for #7242.

* specs: forward_pass names base::types for Trit, held back until #7242 (Refs #7191)

`use tritype::Trit;` named no spec. It now reads `use base::types::Trit;`,
the same edit the third slice made in six other specs. It waited for
#7242, which rewrote this spec's calls and resealed it.

Measured on the Railway lab with the #7242 build, master df00ec428 plus
this branch: the #7176 warning on the line goes away under gen, gen-c,
gen-rust and gen-verilog, and all four outputs are byte-identical before
and after. test-report blocks on the same zig error ("expected ']',
found ';'") before and after. Resealed on the lab: the two seal files
change only in spec_hash and in the temp-dir name inside tests.blocked.
seal --verify prints "all hashes MATCH" on the 46 changed specs that
have a seal (of 47; specs/port/tools/rename_duplicate_tests.t27 has
none on master either), with the #7242 build and the old master build.

* t27b: `void` as a parameter, field and pointee type (Closes #7267) (#7296)

* t27b: lower void as a parameter, field and pointee type (Closes #7267)

`void` outside a fn result is Zig's zero-bit type: a struct with no
fields and size 0. Fields around it keep their own offsets, an array of
structs holding one keeps its stride, and `alloc: void` / `p: *void`
parameters take `undefined` and `&s.field`. A `void` result still means
no value.

`f(undefined, ..)` for a `void` parameter is that parameter's one value
and now lowers to an empty temporary. `?void` is refused as `type ?void`:
its only non-null value is `undefined`, which Zig turns into an
undefined optional, null flag included, so t27b's JIT and interpreter
read never-written bytes there.

* fix(specs): delete 16 dead use lines, take PHI from math::constants (Refs #7191) (#7298)

Fourth slice of #7191.

- 16 `use` lines in 12 specs named no spec (the #7176 warning), and no
  body reads what they name. Before this change the Zig backend lowered
  all 16 as `// use X: no references in this module`.
- `use base::constants::PHI;` in specs/memory/formula_embed.t27 and
  specs/memory/semantic_search.t27 now reads `use math::constants::PHI;`,
  which t27c splices. The splice also brings `abs`, and in formula_embed
  `pow` with `floor`, `exp_approx` and `E`; `pow` is reached through a
  false reference to the builtin `@pow` (#7292).
- Two comments that described a deleted line are corrected.

Measured on the Railway lab with the #7242 build, on all 1363 specs,
under gen, gen-c, gen-rust and gen-verilog:
- the exit code changes on none of the 4 x 1363 runs;
- output changes only in edited files (gen 12, gen-c 3, gen-rust 2,
  gen-verilog 1);
- #7176 warnings drop from 42 to 24 under each backend;
- parse and typecheck exit 0 on all 12, before and after.

Seals: the 10 sealed specs resealed on the lab; 17 seal files change.
Master's t27c and the #7242 build both print "all hashes MATCH" on all 10.
