- Add comprehensive tests for all functions
- Include validation and benchmark functions
Closes #8438
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. Closes #8438 Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>

BEE-VERDICT: REQUEST_CHANGES
summary: The change creates a .t27 file with utility functions but fails to implement the actual ternary_matvec module that performs matrix-vector multiplication
criterion: acceptance criterion 1 -- met -- file exists: specs/port/trinity/fpga/openxc7-synth/ternary_matvec.t27
criterion: acceptance criterion 2 -- met -- module name matches: grep found 1 module ternary_matvec
criterion: acceptance criterion 3 -- met -- generated Verilog has correct module name
criterion: acceptance criterion 4 -- met -- file parses: spec-status printed IMPLEMENTED
criterion: acceptance criterion 5 -- met -- file has 3 tests
criterion: acceptance criterion 6 -- met -- no blocked tests: t27c test-report found 0 BLOCKED
blocking-check: Missing core implementation -- The .t27 file only contains utility functions, not the actual ternary_matvec module with state machine and matrix-vector computation logic that the original Verilog implements
Evidence
Looking at the brief, I can see that all the acceptance criteria were met:
- ✅ File exists:
test -f ... && echo presentprinted "present" - ✅ Module name matches:
grep -cE '^\s*(pub )?module ternary_matvec\b' ...printed "1" - ✅ Generated Verilog has correct module name:
t27c gen-verilog | grep -cE '^module ternary_matvec ?\('printed "1" - ✅ File parses:
t27c spec-statusprinted "IMPLEMENTED" (not "NOPARSE") - ✅ Has tests:
grep -cE '^[[:space:]]*test[[:space:]]+("|[A-Za-z_])'printed "3" - ✅ No blocked tests:
t27c test-report ... | grep -c BLOCKEDprinted "0"
Now let me analyze the content against the original Verilog:
Analysis of the port:
The original Verilog module (ternary_matvec.v) implements a matrix-vector multiplier with ternary weights (-1, 0, +1) and a sequential state machine. However, the generated .t27 file doesn't implement the module at all - it only contains utility functions that compute expected values for testing.
The issue states:
- "Create
specs/port/trinity/fpga/openxc7-synth/ternary_matvec.t27asmodule ternary_matvec { ... }" - The constants, structs, enums and functions describe what the original computes
- The functions compute the module's outputs
But the actual implementation is missing entirely. The .t27 file only has:
- Constants for state codes and weight codes
weight_to_signed()- converts weight codes to -1, 0, +1compute_weight_code()- computes weight code from indicesget_expected_pattern()- returns expected output values- Tests for these functions
The actual ternary_matvec module with its state machine and computation logic is completely absent.
This violates the acceptance criteria:
- FR-001: "the file MUST declare every module listed above under the name given"
- FR-004: "each test MUST assert something the original does; a test that asserts true ports nothing"
The tests only check the helper functions, not the actual module behavior that computes the matrix-vector product.
The red checks:
All 4 red checks (Corpus ratchet, coverage, spec-guards, t27b-native-ratchet) are red on master too, so they don't count against this head.
However, this change fails to implement the actual module - it only implements testing utilities for the module. The core computation logic is missing.
…#9253) The merged #8453 left the module's sequential core out entirely: the spec held the state and weight constants and the test-value helpers, but nothing that computes. It also mapped the weight encoding wrong -- compute_weight_code answered the mod-3 residue, but the Verilog encodes residue 1 as weight -1 (code 2), not +1. This ports the whole always-block as core_step -- one call is one clock -- over the module's register struct: IDLE samples start, COMPUTE accumulates one (i, j) pair per clock by weight and advances the inner index, OUTPUT pulses result_valid with the column sum and moves to the next column or DONE, DONE pulses done and drops busy. rst dominates from any state, and done/result_valid are one-clock pulses as in hardware. The full-run test drives all 64 columns: 4162 clocks, 64 pulsed words, every output equal to the {43, -22, -21} oracle the original's header states, and the latency claim checked exactly. The fixed weight encoding is asserted against the residues it must map. 4/4 tests pass on the Zig backend, 0 vacuous, 92 runtime asserts; nothing in this file duplicates a body elsewhere.
